    Title of the invention: Device for disconnecting from the power supply circuit [0001] Background to the invention
    1. Field of the invention The present invention relates to a device for disconnecting an electrical supply circuit.
    2. Description of the Related Art [0003] For example, a vehicle such as an electric vehicle or a hybrid vehicle is provided with a device for disconnecting the electrical supply circuit, called a service outlet, configured to disconnect the Power supply between an electrical power supply unit and a load in order to ensure operational safety during the maintenance of an electrical system thereof. In such a power supply circuit disconnect device, a device is configured to provide a delay between on and off of a power supply circuit switch and a signal circuit switch and to prevent the generation of sparks and arcing from the remaining current after the signal circuit switch is turned off (see document JP-A-2013-62043).
    The related connector described in JP-A-2013-62043 includes a latch subunit configured to turn off a signal circuit switch before an electrical power circuit switch is turned off by engaging a lever, which is actuated to rotate during the fixing and detachment of the housings, in the middle of the rotation.
    However, a latch release portion formed on the lever and configured to release the latch by the latch sub-unit is usually exposed outside in the connector. Consequently, when the lever is rotated to separate the housings, the lever can be rotated while actuating the exposed latch release portion, and sufficient delay may not be ensured to turn the switch on and off of the power supply circuit and the signal circuit switch.
    Summary of the invention The present invention is made in view of the above circumstances, and an object thereof is to provide a device for disconnecting the electrical supply circuit in which a delay between on and off d 'a main switch unit and a switch sub-unit is reliably ensured, and the occurrence of sparks, arcs or the like resulting from a residual current after the sub-unit switch is off can be favorably prevented.
    In order to achieve the object described above, a device for disconnecting an electrical supply circuit according to the present invention is characterized by the following elements (1) to (4).
    - Power supply circuit disconnection device including: [0008] a first connector housing;
    A second connector housing configured to be adjusted to, and separate from, the first connector housing;
    A lever supported in rotation on the second connector housing and configured to, by being rotated between a separation operating position and a final adjustment operating position, bring the first connector housing and the second housing connector in a separable state of possible separation from each other and a final adjusted state of complete adjustment to each other;
    A latch subunit configured to lock the lever on the second connector housing in a temporary adjusted state in which the lever is disposed in a temporary adjustment operating position between the adjustment operating position final and the separation operation position and a part of the second connector housing is adjusted to the first connector housing;
    A main switch unit configured to be turned on in the final adjusted state and the temporary adjusted state, and off in the separable state;
    A switch subunit configured to be turned on in the final adjusted state, and off in the temporary adjusted state and the separable state; and a latch release portion formed on the lever and configured to release the latch from the lever by the latch sub-unit, in which the latch release portion is covered and not exposed to the outside. in the final adjusted state.
    - Device for disconnection of the electrical supply circuit according to (1), in which the latch release portion is provided on a front side of the lever in a direction of rotation towards the final adjustment operation position of the lever, and wherein the first connector housing has a receiving portion in which the latch release portion is received when the lever is disposed in the final adjustment operating position.
    - Device for disconnecting the electrical supply circuit according to (1) or (2), in which the lever includes a pair of arm portions, the ends of which are supported in rotation on the side surfaces of the second connector housing , and a connection portion which connects the other ends of the pair of arm portions;
    Wherein the latch sub-unit includes a latch sub-claw formed on the second connector housing, and an engaging claw formed on the connection portion configured to engage with the sub-claw lock in the temporary adjustment operating position and configured to be separated from the lock sub-shoe by pressing the lock release portion; and in which the lock release portion is:
    Formed on a second connector housing side on the connection portion, arranged in an opposite position and close to another side surface of the second connector housing when the lever is disposed in the operating position final adjustment, and disposed on an upper surface side of the second connector housing when the lever is disposed in the position of temporary adjustment operation.
    - Device for disconnecting the power supply circuit according to any one of (1) to (3), further including:
    A main lock unit configured to lock the lever disposed in the final adjustment operating position on the second connector housing.
    According to the electrical supply circuit disconnection device configured as (1), when the lever in the final adjustment operating position is turned towards the separation operating position, the lever is locked by the lock sub-unit in the temporary adjustment operation position and is rotationally restricted. Consequently, after the switch sub-unit is turned off, the main switch unit cannot be turned off unless the latch by the latch sub-unit is released and the lever in the position of temporary adjustment operation is rotated to the separation operation position. As a result, the occurrence of arcs, sparks or the like resulting from the remaining current generated by the main switch unit which is turned off immediately after the switch subunit is turned off is prevented.
    In the power supply circuit disconnect device according to the present invention, the latch release portion configured to release the latch by the latch subunit is covered and not exposed to the outside in the state final adjusted. As a result, the lever in the final adjustment operating position can be rotated without actuating the latch release portion, so that the rotation of the lever can be reliably restricted in the temporary adjustment operating position by the lock sub-unit. As a result, the delay between on and off of the main switch unit and the switch subunit is reliably ensured, and the occurrence of sparks, arcs or the like resulting from a current remaining after the switch sub-unit is turned off can be favorably prevented.
    According to the electrical supply circuit disconnection device configured as (2), the latch release portion can be easily received in the reception portion provided in the first connector housing when the lever is rotated for disposition in the final adjustment operation position. Furthermore, since the lock release portion is received in the reception portion, contact with the lock release portion in the final adjusted state can be further reliably prevented, and the delay between on and off the main switch unit and the switch subunit is more reliably ensured.
    According to the electrical supply circuit disconnection device configured as (3), the latch release portion is disposed in an opposite position and close to a side surface of the second connector housing by the lever which is disposed in the final adjustment operating position, so that contact with the latch release portion in the final adjusted state can be further reliably prevented. Further, the latch release portion is disposed on an upper surface side of the second connector housing by the lever which is disposed in the temporary adjustment operating position, so that the latch release portion can be pressed in the temporary adjusted state to separate the engaging claws from the lock sub-claws and release the lock easily.
    According to the electrical supply circuit disconnection device configured as (4), a neglected rotation of the lever is restricted since the main lock unit is provided, so that the final adjusted state can be maintained in which the first connector housing 10 and the second connector housing 20 are completely adjusted to each other.
    Effect of the invention [0031] According to the present invention, it is possible to propose a device for disconnecting the electrical supply circuit in which a delay between on and off of a main switch unit and of a switch sub-unit is reliably ensured, and the occurrence of sparks, arcs or the like resulting from a residual current after the switch sub-unit is turned off can be favorably prevented.

Figure 4 is a perspective view of the disconnection device of the power supply circuit in which the first connector housing and the second connector housing are in a temporary adjusted state.
    As shown in Figures 1 to 4, a device for disconnecting the power supply circuit 1 according to the present embodiment includes a first connector housing 10 and a second connector housing 20. The second connector housing 20 is configured to be adjusted to, and separated from, the first connector housing 10. The second connector housing 20 includes a lever 40. The lever 40 is rotated on the second connector housing 20, and applies, by rotation of the lever 40, an adjustment force and a separation force between the second connector housing 20 and the first connector housing 10. By rotation of the lever 40, the first connector housing 10 and the second connector housing 20 are moved along an insertion-removal direction A to be adjusted to one another and separated from each other.
    The electrical supply circuit disconnection device 1 is, for example, a so-called service outlet configured to disconnect the energy supply between an electrical supply unit and a load for the purpose ensure operational safety when servicing an electrical system in a vehicle such as an electric vehicle or a hybrid vehicle. Specifically, the power supply between the power supply unit and the load is allowed when the second connector housing 20 is fitted to the first connector housing 10, and the power supply between the power supply unit and the load is disconnected when the second connector housing 20 is separated from the first connector housing 10.
    The first connector housing 10 is formed from an insulating synthetic resin. The first connector housing 10 has a flange portion 10a projecting towards an external periphery, and is mounted on an electrical supply device or the like by fixing the flange portion 10a to a housing. In addition, at one end side of the first connector housing 10, a receiving portion 19 is formed in the flange portion 10a.
    The first connector housing 10 includes a tubular receiving portion 12 having an open top surface. The tubular receiving portion 12 is rectangular in plan view. Furthermore, side wall portions 11 rest on the two side portions of the tubular reception portion 12 of the first connector housing, and support protrusions 11a are formed on the side wall portions 11 near the other end of the first connector housing 10.
    The second connector housing 20 is formed of an insulating synthetic resin, and includes an external peripheral tubular portion 21 and an adjustment portion 22 on an internal side of the external peripheral tubular portion 21. The second connector housing 20 is provided with a pair of support shafts 23 protruding from the two side surfaces of the outer peripheral tubular portion 21. A pair of main latch protrusions 28 is formed near one end on the two side surfaces of the outer peripheral tubular portion 21 of the second connector housing 20. In addition, a pair of latch sub-claws 29 is formed at one end of the outer peripheral tubular portion 21 of the second connector housing 20. The latch sub-claws 29 project outwardly from an upper portion of the second connector housing 20.
    The adjustment portion 22 of the second connector housing 20 is oval in shape in a slightly smaller plan view than the external shape of the tubular receiving portion 12 of the first connector housing 10. The second housing connector 20 is adjusted from an upper side of the tubular receiving portion 12 so that the adjustment portion 22 is adjusted to the tubular receiving portion 12 of the first connector housing 10. Next, the tubular portion reception 12 enters between the adjustment portion 22 and the external peripheral tubular portion 21 by adjusting the adjustment portion 22 in the reception tubular portion 12.
    Figures 5A and 5B are views showing an internal structure of the power supply circuit disconnect device, in which Figure 5A is a sectional view taken along a direction of the width of the circuit disconnect device d power supply, and Figure 5B is a partial sectional view taken in a direction along the length of the disconnection device of the power supply circuit.
    As shown in Figure 5A, the first connector housing 10 is provided with a pair of main terminals 13 in the tubular receiving portion 12. The main terminal 13 is configured by an L-shaped bus bar in side view formed from a conductive metal material. In the main terminal 13, one end portion is a male terminal portion 14, and the other end portion extending in a direction orthogonal to the male terminal portion 14 is a connection portion 16. The portions of male terminal 14 of the respective main terminals 13 are arranged so as to sandwich a portion of insulating plate 17 formed from a part of the first connector housing 10. The connection portions 16 of the main terminals 13 are connected to lines d power supply 2 from an electrical power supply device or the like.
    A main busbar 24 formed of a conductive metal material is formed inside the second connector housing 20. The main busbar 24 is substantially U-shaped in the side view having a pair of portions of contact plate 25. The pair of male terminal portions 14 of the main terminals 13 of the first connector housing 10 is inserted between the contact plate portions 25 of the main busbar 24. When the male terminal portions 14 of the terminals main 13 are inserted between the contact plate portions 25 of the main busbar 24, the power supply lines 2 connected to the main terminals 13 are electrically connected to each other via the main busbar 24.
    As shown in Figure 5B, the first connector housing 10 is provided with a pair of sub-terminals 18 formed of female terminals inside the tubular receiving portion 12. The sub-terminals 18 are connected to signal lines 3.
    A busbar 26 formed of a conductive metal material is formed inside the adjustment portion 22 of the second connector housing 20. The busbar 26 includes a pair of terminal portions male 27. The male terminal portions 27 of the bus sub-bar 26 can be connected to the sub-terminals 18 of the first connector housing 10 respectively. When the male terminal portions 27 of the bus sub-bar 26 are connected to the sub-terminals 18, the signal lines 3 connected to the sub-terminals 18 are electrically connected to each other via the bus sub-bar 26.
    As described above, the device for disconnecting the electrical supply circuit 1 includes a main switch unit MSw configured by the main terminal 13 and the contact plate portion 25 of the main busbar 24, and a switch sub-unit SSw configured by the sub-terminal 18 and the male terminal portion 27 of the bus sub-bar 26. In an electrical supply device including the device for disconnecting the electrical supply circuit 1, a power supply circuit is formed when the main switch unit MSw is turned on and the power supply lines 2 are electrically connected to each other, and a signal circuit is formed when the switch subunit SSw is on and signal lines 3 are electrically connected to each other. In the power supply device including the power supply circuit disconnect device 1, even if the main switch unit MSw is turned on and the power supply circuit is formed, the power supply circuit n is not brought into a connected state until the switch sub-unit SSw is turned on and the signal circuit is formed. Namely, only when the main switch unit MSw and the switch subunit SSw are both on, the power supply circuit is brought into the connected state.
    As shown in Figures 1 to 4, the lever 40 is formed of a synthetic resin and includes a pair of arm portions 41 and a connection portion 42. Ends of the arm portions 41 are connected by the portion connection 42, and each of the arm portions 41 includes a shaft receiving hole 44 near the other end. The support shafts 23 of the second connector housing 20 are inserted into the shaft receiving holes 44 of the arm portions 41, so that the lever 40 is supported in rotation relative to the second connector housing 20. The other end of the arm portion 41 of the lever 40 is a pressing portion 46 having a curved surface 45.
    The lever 40 rotatably supported by the second connector housing 20 rotates between a separation operation position (position shown in Figures 1 and 2) along the direction of insertion-removal A and a position d 'final adjustment operation (position shown in Figure 3) along a direction orthogonal to the direction of insertion-removal A.
    Figures 6A and 6B are views showing a lever lock mechanism, in which Figure 6A is a partial sectional view taken in the direction of the width of the disconnection device of the power supply circuit in the final adjusted state showing the main lock unit, and Fig. 6B is a side view of the power supply circuit disconnect device in the temporary adjusted state in which the lever is seen in section.
    As shown in Figure 6A, main latch parts 51 are formed on the second connector housing side 20 in respective arm portions 41 of the lever 40. The main latch parts 51 are formed in an extension direction arm portions 4L The main latch parts 51 engage with the main latch protrusions 28 of the second connector housing 20 in a state where the lever 40 is disposed in the final adjustment operating position. Accordingly, the lever 40 is locked in the final adjustment operation position by the main lock pieces 51 engaging with the main lock protrusions 28. In addition, the main lock protrusion 28 and the work piece master lock 51 configure a master lock unit MR.
    As shown in Figure 6B, a latch plate sub-portion 60 is integrally formed with the connection portion 42 in the lever 40. The latch plate sub-portion 60 includes a latch release portion 61 and a pair of engaging claws 62. The latch plate sub-portion 60 is provided to project forward in a direction of rotation from the separation operation position to the adjustment operation position end of the lever 40. The engagement claws 62 are formed on both sides of the latch release portion 61 and are formed on a side opposite to the connection portion 42. When the lever 40 in the operating position d final adjustment is turned to the separation operation position, the engagement claws 62 of the latch plate sub-portion 60 engage with the latch sub-claws 29 formed on the second connector housing 20 in the middle of rotation. As a result, the lever 40, which is rotated from the final adjustment operating position to the separation operating position, is temporarily locked in the middle of the rotation. A position where the lever 40 is locked in the middle of the rotation is a temporary adjustment operation position (position shown in Figure 4). The latch sub-claw 29 and the engagement claw 62 configure a latch sub-unit SR. The latch plate sub-portion 60 is elastically deformed by pressing the latch release portion 61, the engagement claws 62 are spaced from the latch sub-claws 29 and the engagement state is released, if although the lever lock 40 in the temporary adjustment operation position is released.
    Figure 7 is a partial sectional view taken in the direction of the length of the disconnection device of the power supply circuit in the final adjusted state.
    As shown in Figure 7, in a state where the lever 40 is disposed in the final adjustment operation position, the bolt plate sub-portion 60 comprising the latch release portion 61 and the claws engaging 62 of the latch subunit SR is received in a receiving portion 19 formed in the flange portion 10a of the first connector housing 10. Consequently, in the final adjusted state, the subunit SR lock is in a state that the lock release portion 61 configured to be pressed so as to release the lock enters the interior of the electrical power circuit disconnect device 1 and cannot be in contact.
    Subsequently, in the electrical supply circuit disconnection device 1 including the main lock unit MR and the lock sub-unit SR, will be described cases where the second connector housing 20 is adjusted to , and separated from the, first connector housing 10.
    Adjustment case In order to adjust the second connector housing 20 to the first connector housing 10, the second connector housing 20 in which the lever 40 is disposed in the separation operating position is brought near the first connector housing 10. Next, the adjustment portion 22 of the second connector housing 20 is adjusted in the tubular receiving portion 12 of the first connector housing 10 in the state of fixing or detachment (see the figure 2).
    In the state of fixation or detachment, the lever 40 in the separation operating position is turned towards the final adjustment operating position. Then, the curved surface 45 of the pressure portion 46 of the lever 40 abuts the support protrusion 11a formed on the side wall portion 11 of the first connector housing 10 and slides on the curved surface 45. As a result, a an adjustment force is applied between the first connector housing 10 and the second connector housing 20, and the second connector housing 20 is pulled into the first connector housing 10.
    When the lever 40 reaches the final adjustment operation position, the first connector housing 10 and the second connector housing 20 are ultimately adjusted to each other in the final adjusted state (see figure 3). In the final adjusted state, the main lock pieces 51 of the lever 40 engage with the main lock protrusions 28 of the second connector housing 20, and neglected rotation of the lever 40 is restricted. Namely, the main latch unit MR maintains the final adjusted state in which the first connector housing 10 and the second connector housing 20 are ultimately adjusted to each other.
    In the final adjusted state, the contact plate portions 25 of the main bus bar 24 are connected to the male terminal portions 14 of the main terminals 13. Namely, the main switch unit MSw is on, and the power supply lines 2 connected to the main terminals 13 are electrically connected to each other via the main bus bar 24. In addition, the male terminal portions 27 of the bus sub-bar 26 are connected to the sub-terminals 18 Namely, the switch sub-unit SSw is on, and the signal lines 3 connected to the sub-terminals 18 are electrically connected to each other via the bus sub-bar 26.
    Separation case In order to separate the second connector housing 20 from the first connector housing 10, the lever 40 disposed in the final adjustment operating position is grasped and pulled up. Then, the main lock piece 51 of the lever 40 is moved away from the main lock protrusions 28 of the second connector housing 20, the lock of the lever 40 is released by the main lock unit MR configured to maintain the final adjusted state, and the lever 40 is turned to the separation operation position.
    When the lever 40 is turned towards the separation operating position, the pressure portion 46 of the lever 40 abuts and slides on a surface of the flange portion 10a of the first connector housing 10 as the lever 40 turned. As a result, a separating force is applied between the first connector housing 10 and the second connector housing 20. As a result, the second connector housing 20 in the final adjusted state to the first connector housing 10 is pulled away from the first connector housing 10 and moved to a separation direction.
    When the rotary lever 40 reaches the temporary adjustment operation position, the engaging claws 62 of the latch plate sub-portion 60 engage with the latch sub-claws 29 of the second connector housing 20 to operate as the SR lock sub-unit, so that the lever 40 is locked in the temporary adjustment operation position and rotation is restricted. As a result, the first connector housing 10 and the second connector housing 20 are in the temporary adjusted state (see Figure 4).
    In the temporary adjusted state, the male terminal portion 27 of the bus sub-bar 26 is extracted by pulling the sub-terminal 18. Namely, the switch sub-unit SSw is off, and the electrical connection between signal lines 3 is released. In the temporary adjusted state, the contact plate portion 25 of the main busbar 24 is maintained in the state of connection to the male terminal portion 14 of the main terminal 13. Namely, the switch unit main MSw is kept on, and the electrical connection between the power supply lines 2 is maintained.
    From the temporary adjusted state, the latch release portion 61 of the latch plate subportion 60 of the latch subunit SR is pressed. Then, the latch plate sub-portion 60 is elastically deformed by pressing the latch release portion 61, the engagement claws 62 are moved away from the latch sub-claws 29 and the engagement state is released , so that the lever lock 40 by the lock sub-unit SR in the temporary adjustment operation position is released.
    Once the latch by the latch subunit SR is released, the rotary lever 40 is again turned to the separation operating position. Then, the separation force is applied between the first connector housing 10 and the second connector housing 20 again by rotation of the lever 40, and the second connector housing 20 is pulled away from the first connector housing 10, so that the first connector housing 10 and the second connector housing 20 are in a separable state (see Figure 2).
    As described above, when the second connector housing 20 is moved from the temporarily adjusted state with the first connector housing 10 towards the separation direction and becomes the separable state, the contact plate portion 25 from the main busbar 24 is moved away from the male terminal portion 14 of the main terminal 13. As a result, the main switch units MSw are turned off, and the electrical connection between the power supply lines 2 is released.
    Then, when the second connector housing 20 is removed by traction from the first connector housing 10, the adjustment portion 22 of the second connector housing 20 is extracted by traction from the tubular reception portion 12 of the first housing connector 10, and the second connector housing 20 is separated from the first connector housing 10 (see Figure 1).
    As described above, in the electrical supply circuit disconnection device 1 described above, the main switch unit MSw is turned on in the final adjusted state locked by the main lock unit MR as well as in the temporary adjusted state locked by the SR lock sub-unit; the switch sub-unit SSw is switched on in the final adjusted state locked by the main lock unit MR, and is switched off in the temporary adjusted state locked by the lock sub-unit SR. Therefore, in the disconnection device of the power supply circuit 1, after the switch sub-unit SSw is switched off and the electrical connection between the signal lines 3 is released, if the lock by the sub-unit SR lock is not released, the main switch unit MSw is turned off, and the electrical connection between the power supply lines 2 cannot be released. Consequently, the occurrence of arcs, sparks or the like resulting from a remaining current generated by releasing the connection between the power supply lines 2 immediately after releasing the connection between the signal lines 3 can be prevented.
    However, if the latch release portion 61 configured to release the latch by the latch subunit SR is usually exposed to the outside, when the lever 40 in the final adjustment operation position is rotated towards the separation operating position, the lever 40 can be rotated while actuating the latch release portion 61 exposed to the outside. In this case, the lever 40 is not restricted in rotation by the latch sub-unit SR in the position of temporary adjustment operation and is turned from the position of final adjustment operation to the position of separation operation, which can cause the first connector housing 10 and the second connector housing 20 in the final adjusted state to be suddenly brought into the separable state. For this reason, a sufficient delay between on and off of the main switch unit MSw and the switch subunit SSw is not guaranteed, and the occurrence of arcs, sparks or the like resulting of a residual current may not be sufficiently prevented.
    However, according to the electrical supply circuit disconnection device 1 of this embodiment, the latch release portion 61 configured to release the latch by the latch subunit SR is covered by the first housing of connector (in particular by the receiving portion 19) and not exposed to the outside in the final adjusted state. Accordingly, the lever 40 in the final adjustment operating position can be rotated without actuating the latch release portion 61, so that the rotation of the lever 40 can be reliably restricted in the operating position d 'temporary adjustment by the SR lock sub-unit. Therefore, the delay between on and off of the main switch unit MSw and the switch subunit SSw is reliably ensured, and the occurrence of sparks, arcs or the like resulting from a current remaining after the switch sub-unit SSw is turned off can be favorably prevented.
    In the disconnection device of the power supply circuit 1 according to the present embodiment, the latch release portion 61 can be easily received in the reception portion 19 formed in the first connector housing 10 by making turn the lever 40 to be placed in the final adjustment operation position. Furthermore, since the latch release portion 61 is received in the reception portion 19, contact with the latch release portion 61 in the final adjusted state can be more reliably prevented, and the delay between on and off the main switch unit MSw and the switch sub-unit SSw is even more reliably ensured.
    In addition, according to the electrical supply circuit disconnection device 1 of this embodiment, the latch release portion 61 is arranged in an opposite position and close to a side surface of the second connector housing. By arranging the lever 40 in the final adjustment operation position, so that contact with the latch release portion 61 in the final adjusted state can be more reliably prevented. Furthermore, the latch release portion 61 is disposed on an upper surface side of the second connector housing 20 by placing the lever 40 in the temporary adjustment operating position, so that the latch release portion 61 can be pressed in the temporary adjusted state to separate the engaging claws 62 from the lock sub-claws 29 and easily release the lock.
    The invention is not limited to the above embodiment, and can be modified appropriately, improved or the like. In addition, materials, shapes, dimensions, reference numbers, arrangement locations or the like of component parts in the embodiment described above are optional and are not limited as long as the object of the present invention can be achieved .
