    Field of the invention
    The present invention relates to a conductor module.
    Description of Related Art
    A conventional conductor module is applied to a battery module including a plurality of battery cells. The driver module includes, for example, a plurality of bus bars and a status detector. The bus bar is electrically connected to one of two electrode terminals of a battery cell and to the electrode terminals of two battery cells which are adjacent to each other. The state detector includes a detection conductor for detecting the voltage of each battery cell (see, for example, Japanese Patent No. 5,223,607).
    The conductor module further includes a connection portion which electrically connects each bus bar to the detection conductor by, for example, soldering or welding the detection conductor to the bus bar on which the detection conductor is disposed. In certain conductive modules, the bus bar to which the detection conductor is connected is received in a reception space defined in a reception unit before being connected to the electrode terminal.
    When the bus bar is to be fixed in the docking box, a locking portion for locking the bus bar is formed in a wall portion which defines the docking space to prevent the bus bar from moving relative to the reception box in a direction opposite to a direction in which the bus bar is inserted in the reception space. Since the locking portion is elastically deformed when the bus bar is inserted, the locking portion is extended in the direction in which the bus bar is inserted to thereby make the locking portion elastically deformable. The foregoing requirement requires a length in the direction of insertion, specifically, a height of the docking box so that the locking portion for locking the bus bar is formed. Specifically, fixing the bus bar in the reception box is an obstacle to reducing the height of the reception box.

The Z direction is a vertical direction in the conductor module and is orthogonal to the layout direction and the width direction.
    This conductive module 1 according to the embodiment must be assembled, as illustrated in FIG. 1, with a battery module 100. The battery module 100 has a modular configuration which includes, for example, a plurality of battery elements 101, such as secondary batteries, arranged in the direction of arrangement. The battery module 100 is mounted on, for example, an electric vehicle (EV) or a hybrid vehicle (HC, PHV) and used to power a rotary electric machine serving as a source of training in electrical energy and for storing (charging) electrical energy generated by the rotary electric machine. The battery module 100, for example, includes a plurality of cell elements 101 connected in series with each other to thereby provide high battery output corresponding to vehicle output requirements. The battery cells 101 consist of two rows of groups of electrode terminals 103 which are spaced apart from each other in the width direction and which include electrode terminals 102 (a positive electrode terminal and a d 'negative electrode) arranged on respective ends in the width direction. The electrode terminal groups 103 each consist of a plurality of electrode terminals 102 arranged in the direction of arrangement in the battery module 100. In the battery module 100, a conductive module 1 is associated and assembled to each of the electrode terminal groups 103 and the conductive module 1 connects the electrode terminals 102 (the positive electrode terminals and the negative electrode terminals) of the battery cells 101 in series with each other.
    The battery cells 101 according to the embodiment are arranged such that the electrode terminal 102 of a first battery cell 101 has a polarity opposite to the polarity of the electrode terminal 102 of a second battery cell battery 101 adjacent to the first battery member 101 in the direction of arrangement. In addition, the two groups of electrode terminals 103 are configured as follows. Specifically, in a first group of electrode terminals 103, the electrode terminal 102 on a first end of both ends in the direction of arrangement is defined as the termination electrode terminal and, in a second group of terminals d electrode 103, the electrode terminal 102 on a second end of both ends in the direction of arrangement is defined as the termination electrode terminal having a polarity opposite to the polarity of the termination electrode terminal of the first group of electrode terminals 103. The two termination electrode terminals are electrically connected to each other, for example, by an inverter. This establishes an electrical connection of the battery module 100 with an external device.
    The driver module 1 must connect at least a plurality of battery cells (101) in series with each other. As illustrated in Figures 1 to 5, the conductor module 1 includes a bus bar 2, a power cable terminal 3, a docking box 4, a fixing member 5, a fixing member 6, a terminal 7, a status detector 8 and a power cable 9. The conductor module 1 electrically connects the bus bar 2, the power cable terminal 3 and the detection terminal 7 to the electrode terminal 102 as a connection target.
    Bus bar 2 is a connection conductor. As illustrated in FIGS. 1 to 5, the bus bar 2 is electrically connected to a first of the two electrode terminals 102 of the battery element 101.

The bus bar 2 is made of an electrically conductive material, such as metal, in the form of a flat plate. According to the embodiment, the bus bar 2 is formed in the form of a rectangular plate having a longitudinal direction extending in the direction of arrangement as seen in the vertical direction. The bus bar 2 has terminal holes 21 and through holes 22.
    The electrode terminals 102 are inserted into the terminal holes 21. The terminal holes 21 each pass through from a first conductor surface 2a to a second conductor surface 2b which are opposite to each other in the vertical direction. According to the embodiment, the bus bar 2 has two terminal holes 21 associated with respective electrode terminals 102 which must be connected to the bus bar 2. The two terminal holes 21 are spaced from one another in the layout direction. Note that the bus bar 2 is fixed to the electrode terminals 102 as follows. Specifically, for example, in a condition in which the electrode terminals 102 are inserted into the terminal holes 21 of the bus bar 2, nuts not shown are threaded with threaded grooves in the leading ends of the terminals electrode 102 protruding from the side of the first conductor surfaces 2a of the terminal holes 21.
    Fixing lugs 52, to be described below, of the fixing member 5 are inserted into the through holes 22. The through holes 22 each pass from the first conductor surface 2a to the second conductor surface 2b which are opposite to each other in the vertical direction. According to the embodiment, the bus bar 2 has two through holes 22 associated with two respective fixing holes 43 to be described below. The through holes 22 are spaced from each other in the arrangement direction. It is noted that the two through holes 22 are formed on a part of the detection terminal 7 disposed on the bus bar 2 in the direction of arrangement. In addition, the two through holes 22 are arranged, in the width direction, on the side closer to a third reception space 4c, to be described below, than are the terminal holes 21.

According to the embodiment, the cable terminal d supply 3 constitutes a third connection conductor which is different from the bus bar 2 as the first connection conductor and from the detection terminal 7 as the second connection conductor. The power cable terminal is directly and electrically connected to the termination electrode terminal among the electrode terminals 102 of the electrode terminal group 103. The power cable terminal 3 is made of a material electrically conductive, such as metal, in the form of a flat plate. According to the embodiment, the power cable terminal 3 is formed in the form of a rectangular plate having a longitudinal direction extending in the width direction as seen in the vertical direction.

The cylinder portion 32 is curved so that the crimped portions 32a and 32b have leading ends approaching one another, thereby crimping the supply conductors 91 on the cable terminal supply 3.
    The terminal hole 33 receives the electrode terminal 102 as a terminating electrode terminal inserted therein. The terminal hole 33 passes through a first conductor surface 3a to a second conductor surface 3b which are opposite to each other in the vertical direction.

In addition, the battery module control unit 200 can output the voltage information acquired on a battery ECU which controls the battery module 100. The battery ECU performs charge and discharge control of the battery module 100 based on the voltage information. The state detector 8 includes the detection conductor 81 and the insulator 82. According to the embodiment, the state detector 8 is a wire corresponding to the bus bar 2 and is molded in one piece so as to cover the detection conductor 81 in the insulation 82.
    The detection conductor 81 electrically connects the detection terminal 7 to the battery module control unit 200. The detection conductor 81 is electrically conductive and deformable and consists of a plurality of wires made, for example of copper or aluminum, stranded together. The detection conductor 81 has a first end directly and electrically connected to the first conductor surface 7a and a second end electrically connected to the battery module control unit 200 via a connector not shown. A portion of the insulation 82 covering the first end of the detection conductor 81 is peeled off in advance to cause the first end of the detection conductor 81 to be exposed to the outside from a leading end of the insulation 82 .
    The insulator 82 covers the detection conductor 81. The insulator 82 is electrically insulating and elastically deformable. The insulator 82 consists, for example, of a synthetic resin. The insulator 82 is formed to extend in the arrangement direction. The insulator 82 is folded from the arrangement direction in the width direction and disposed on the first conductor surface 7a.
    The following describes an assembly procedure for the conductor module 1. It is noted that the following assembly procedure assumes that the power cable 9 is electrically connected to the power cable terminal 3 in advance and that the detection terminal 7 is electrically connected to the state detector 8 in advance. As illustrated in FIG. 3, an assembly operator first places the busbar 2 relative to the reception box 4 so that the second conductor surface 2b faces the first fixing body surface 41a in the first reception space 4a and such that the through holes 22 in the bus bar 2 are aligned with the respective fixing holes 43 in the vertical direction. The assembly operator brings the bus bar 2 near the reception box 4, causing the second conductor surface 2b to be in contact with the first fixing body surface 41a. At this time, the through holes 22 communicate with the respective fixing holes 43. The assembly operator then places the detection terminal 7 on the first conductor surface 2a of the bus bar 2 so that part of the detection terminal 7 is disposed between the through holes 22 At this time, the detection terminal 7 is received in the first reception space 4a and the state detector 8 is received in the third reception space 4c. The assembly operator then arranges the fixing member 5 relative to the busbar 2 so that the opposite surface 51a faces the first conductor surface 2a and so that the fixing lugs 52 of the 'fixing member 5 are aligned with the respective through holes 22 of the bus bar 2 in the vertical direction. At this time, the first conductor surface 7a of the detection terminal 7 placed on the first conductor surface 2a of the bus bar 2 faces the opposite surface 51a. The assembly operator then brings the fixing member 5 near the bus bar in the vertical direction. At this time, the fixing tabs 52 are inserted into the respective through holes 22 from the first conductor surface side 2a and into the respective fixing holes 43, thereby protruding from the second surface side of the fixing body 41b. In addition, the main body 51 is in contact with the detection terminal 7 in a condition in which the main body 51 presses the detection terminal 7 and the bus bar 2 against the first surface of the fixing body 41a. Then, the power cable terminal and the receiving box 4 are arranged so that the power cable terminal 3 is disposed between the fixing holes 44 and so that the second conductive surface 3b makes facing the first fixing body surface 41a in the second reception space 4b. Then, the assembly operator brings the power cable terminal 3 close to the reception box 4 so that the second conductor surface 3b is in contact with the first fixing body surface 41a. Then, the assembly operator arranges the fixing member 6 relative to the receiving housing 4 so that the opposite surface 61a faces the first surface of the fixing body 41a and so that the tabs of fixing 62 of the fixing member 6 are aligned with the fixing holes 44 in the vertical direction. Then, the assembly operator brings the fixing member 6 near the reception box 4 in the vertical direction. At this time, the fixing tabs 62 are inserted into the respective fixing holes 44 from the first surface side of the fixing body 41a and protrude from the second surface side of the fixing body 41b. In addition, the main body 61 is in contact with the power cable terminal 3 in a condition in which the main body 61 presses the power cable terminal 3 against the first fixing body surface 41a. Then, the assembly operator applies an external force towards the reception box side 4 in the vertical direction, while heating the fixing lugs 52 and 62 projecting from the second fixing body surface 41b of the housing. home 4. For example, in a condition in which a mold, in which is formed in advance a transfer surface identical to the shapes of the leading ends 52a and 62a in the fixed condition, is heated, the operator of assembly presses the leading ends 52a and 62a before the condition fixed towards the reception box side 4 in the vertical direction. The previous step causes the leading ends 52a and 62a of the fixing lugs 52 and 62 to deform elastically so as to surround the circumferences of the fixing holes 43 and 44. When they are then cooled, the leading ends 52a and 62a maintain the distorted conditions at room temperature. The electrode terminals 102 are then inserted into the terminal holes 21, 33 and 73 exposed on the outside of the reception box 4 through the openings 4d, 4e, and are electrically connected to the bus bar 2, at the power cable terminal 3 and detection terminal 7, respectively, to thereby assemble the conductive module 1 to the battery module 100. This completes the assembly of the conductive module 1 and the fixed condition is reached, in which the bus bar 2, the power cable terminal 3 and the detection terminal 7 are fixed to the reception unit 4 by the fixing members 5 and
    6.
    As described above, the conductor module 1 according to the embodiment incorporates the fixing members 5 and 6 for fixing the bus bar 2, the power cable terminal 3 and the detection terminal 7 to the reception unit 4 in the condition set.
    in place of the housing
    Specifically, the conductive module 1 fixes the bus bar 2, the power cable terminal 3 and the detection terminal 7 to the reception box using another reception element 4. Thus, when the bus bar 2, the terminal of power cable 3 and the detection terminal 7 must be fixed by the reception box 4, the reception box 4 does not require a function to fix the bus bar 2, the power cable terminal 3 and the detection terminal 7. Thus, the conductive module 1 is only necessary to form, in the reception unit 4, a space (the first reception space 4a and the second reception space 4b) of a total length in the vertical direction of the connection conductors (the bus bar 2, the power cable terminal 3 and the detection terminal 7) and the fixing members 5 and 6, so that a reduction in the height of the housing Host 4 can be favored. The previous characteristic allows the driver module 1 to carry out the size reduction.
    In the conductor module 1 according to the reduction module, the bus bar 2 is fixed by the fixing member 5 to the reception unit 4 in a condition in which the fixing lugs 52 are inserted in the respective through holes 22 of the bus bar 2. Thus, the conductor module 1 allows the bus bar 2 to be reliably fixed to the reception box 4, with respect to which the bus bar 2 is to a housing in fixed to the reception box 4 by the fixing member 5 through a part of the bus bar 2 which is simply sandwiched between the fixing lugs 52. In addition, the bus bar 2 cannot move relative to the reception box 4 in the layout direction and in width direction, so that the bus bar 2 can be reliably positioned relative to the docking box 4.
    In the conductor module 1 according to the embodiment, the bus bar 2 and the detection terminal 7 are simultaneously fixed to the reception box 4 by the fixing member 5. Thus, the conductor module 1 allows a plurality of conductors of different connection laminates on top of each other to be fixed to the reception box 4 by fixing 5. Thus, the module has a greater number of connection conductors 2, 3 and 7 to be fixed to the reception box 4 by a smaller number of fixing members 5 and 6.
    In the conductor module 1 according to the mode of the bus bar 2 and the detection terminal 7 to be fixed to a single electrode terminal 102 are fixed to the reception unit 4 by a single fixing member 5. This arrangement allows the bus bar 2 and to the detection terminal 7 fixed to the reception unit 4 to establish an electrical connection with an adjacent electrode terminal 102 and to establish an electrical connection between the electrode terminal 102 and the battery module control 200.
    The conductor module 1 according to the embodiment has been described for a case in which a set of a single conductor member 1 allows production, of the bus bar 2 and of the detection terminal 7 is received in the reception unit 4. The case is nevertheless only illustrative and not limiting. The reception box 4 can include a plurality of first reception spaces 4a defined therein and arranged in the direction of arrangement. Each of the first reception spaces 4a can then accommodate a bus bar 2 and a detection terminal 7, and the bus bar 2 and the detection terminal 7 can then be fixed to the reception box 4 by the fixing member 5 .
    The conductor module 1 according to the embodiment has been described for a case in which the bus bar 2 and the detection terminal 7 are fixed to the reception unit 4 by the fixing member 5. The case is however only illustrative and not limiting. The first reception space 4a can accommodate only the bus bar 2, and only the bus bar 2 can then be fixed to the reception box 4 by the fixing member 5. In this case, the opposite surface 51a of the fixing member 5 is in contact with the first conductor surface 2a of the bus bar 2.
    In the conductive module 1 according to the embodiment, the fixing members 5 and 6 have each been described to be made of a synthetic resin capable of undergoing plastic deformation by an external force. The material is nevertheless only illustrative and not limiting. A metal capable of undergoing plastic deformation, such as aluminum or iron having electrical conductivity, can be used to form the fixing members 5 and 6. In this case, the fixing lugs 52 and 62 are each bent in directions to approach each other when looking in the width direction in the fixed condition, to thereby come into contact with the second fixing body surface 41b. Specifically, the mounting tabs 52 and 62 may have the respective leading ends 52a and 62a bent inward.
    In the conductor module 1 according to the embodiment, the reception box 4 has been described as a fixing body. The arrangement is however only illustrative and not limiting, and a flexible flat cable (FFC) or a flexible printed wiring board (FPC) can be used.
    The conductor module according to the aspect of this embodiment includes the fixing member for fixing the connection conductor to the fixing body. Thus, the fixing body does not require a function to fix the bus bar. The aspect of the present embodiment can thus achieve an effect consisting in promoting the reduction in size.
    Although the invention has been described with respect to the specific embodiment for a complete and clear description, the appended claims should not be so limited but should be interpreted as encompassing all modifications and other constructions which may appear to man of the profession and which fall precisely into the basic education exposed here.
