    CONNECTION HOUSING AND CONNECTION SYSTEM
    FIELD OF THE INVENTION
    The present invention relates to a terminal housing comprising a rigid housing body for receiving a device connection, and a cable guide for receiving a connected at a transition with a cable lug cable end of a cable, wherein the lug for establishing an electrical connection between the cable and the device port, preferably in a connected to the cable end state in the rigid housing body is inserted.
    In addition, the invention relates to a connection system comprising a connection housing according to the invention, a cable and a cable lug.
    STATE OF THE ART
    Connection housing and connection systems for a means of a cable lug with a device connection, in particular a positive pole on the starter of a motor, connected cable are basically known.
    Such known connection housing in this case comprise a rigid housing body, within which the device connection is received. In order to connect the cable to the device connection, a cable lug connected to the cable can be inserted into the housing body in order to be connected to the device connection there. The connection point between the cable and the housing body is sealed by means of an additional sealing element. Although this makes it possible to achieve the desired sealing of the electrical connection against external force, splash water, contamination, etc., the fact that the cable lug in particular has been completely accommodated within a dimensionally stable part of the connection housing has considerable disadvantages with regard to the flexibility and economy of such connection housing connected.
    These disadvantages are based on the fact that the cable connected to the device connection is usually at certain distances from others
    Device connection must surround surrounding components - for example, a motor - and therefore must usually protrude from the device connection at a certain angle. In order to guarantee such sticking, it is common for a contacting element of a cable lug which is angularly shaped to form a transition - a location where the cable is crimped or otherwise connected to the cable lug - projecting towards the device terminal. While one portion of this contacting element is connected to the device port for the purpose of providing an electrically conductive connection, the other portion directly adjoins the transition, thereby defining the angle at which a cable end nearest the device port protrudes from the device port.
    Since the same generic known connection housing are rigid, the use of differently shaped cable lugs, however, makes each differently shaped connector housing necessary, which are adapted to the particular shape of the cable lug used and thus the particular output direction in which the cable end of the device connection.
    That this is associated with considerable disadvantages in terms of the installation and the efficiency of said connection housing, is obvious. In particular, a separate connection housing must be developed and provided for each individual cable lug, which results in a large number of different housing variants.
    In addition, other concepts, such as that of DE 202012011484 U1, are also known for sealing said electrical connections. In this case, a cable lug is first connected to a cable end of a cable. Subsequently, a screw is inserted into an opening of the cable lug and screwed with a sleeve. The screw fastened by means of the sleeve to the cable lug protrudes over the sleeve in sections and thus offers the possibility of connecting the cable to a device connection - for example by clamping the device connection between the sleeve and a nut screwed onto the projection of the screw. For the purpose of sealing, the assembly made of cable lug, screw and sleeve is overmoulded with plastic in order to create a housing, from which, however, the lug can only be removed if the housing is destroyed.
    It is obvious that even such housing bring significant disadvantages in terms of their adaptation to differently shaped cable lugs, such housing must be made but each for a particular cable lug.
    OBJECT OF THE INVENTION
    It is therefore an object of the present invention to overcome the drawbacks of the prior art described above and to provide a terminal housing which has the advantages of a compact and rigid connection housing according to the prior art and at the same time an adaptation to various
    Outgoing directions of the cable from the device connection allows. The same connection housing according to the invention should therefore be able to be used in conjunction with differently shaped cable lugs.
    Another object of the present invention is to provide therein a terminal system comprising a terminal housing, a cable and a cable lug having the aforementioned advantages.

Thus, cables whose cable ends are to protrude in different outgoing directions from the device connection, in conjunction with the same invention
    Terminal housing can be used. A vote of each used connection housing on the specific cable lug used by the fitter is no longer necessary and takes place in the course of installation of the connection housing automatically by the cable management adapts to the shape of the mounted cable lug.
    The desired protection against external force, moisture and contamination, which could already be achieved by known from the prior art connection housing is ensured even in the connection housing according to the invention. Thus, in fact, the device connection itself can be sealingly received in the rigid housing body. The rigid housing body protects the device connection itself against external forces, moisture and dirt. The cable guide, within which the cable end of the cable, which is to be connected to the device port, can be arranged, is connected by means of its first end portion tightly connected to the housing body or connected. The second end portion of the cable guide is used to seal the recorded in the cable guide end of the cable cable and / or determining the position of the cable end, in particular a penetration depth with which the cable end protrudes into the cable guide.

It is advantageous, in the context of the connection process, in particular, to bring an opening provided in the contacting element of the cable lug into engagement either with a fastening bolt of the device connection if the device connection is already arranged inside the rigid housing body, or at least into one of the openings Making the electrical connection to bring favorable position. In both operations, the second end portion of the cable guide can be used for the corresponding positioning of the cable lug, since the specification of the penetration depth of the cable end in the cable guide for a particular cable lug also determines the position occupying the opening of the contacting within the rigid housing part, as soon as the cable management is connected to the rigid housing body.
    In a further preferred embodiment of the connection housing according to the invention, it is provided that the middle part is at least partially formed as a bellows.

    WAYS FOR CARRYING OUT THE INVENTION
    1 shows a connection system according to the invention in a first embodiment, wherein the connection system comprises a connection housing 1 according to the invention, a cable 2 and a cable lug 7.
    The terminal housing 1 comprises a housing body 4, which is rigid and for receiving a device connection 3, for example a magnetic switch of a motor starter, with which device terminal 3, the cable 2 is to be electrically connected, is used. Preferably, the housing body 4 is made of a thermoplastic to protect the device port 3 and any other housed inside the housing body 4 parts from external force, pollution and liquid entry.
    Furthermore, the terminal housing 1 comprises a cable end of the cable 2 receiving cable guide 5 with a first end portion 8, which serves to connect the cable guide 5 with the housing body 4, a second end portion 10, which serves to seal the connection point between the cable 2 and connector housing 1 and preferably also for fixing the penetration depth of the cable end can be used within the cable guide 5, and with the first end portion 8 and the second end portion 10 interconnecting middle part 9. The middle part 9 is flexible, to a deflection of the central part 9 relative to the housing body 4 and / or with respect to the first end portion 8 to allow.
    As can be seen from Fig. 1, the central part 9 of the cable guide 5 bellows may be formed. The bellows, which is preferably made of a permanently elastic material, particularly preferably made of an elastomer, gives the central part 9 the necessary flexibility and makes it possible to adapt the cable guide 5 to certain requirements of the electrical connection between the cable 2 and the device connection 3.
    In particular, it is possible by the flexible design of the central part 9, the same cable guide 5 - and thus the same housing 1 - to use for such electrical connections between a device port and a cable, which is with respect to an angle at which the cable end of the device port 3, and thus differ from each other in terms of a direction of departure of the cable end of the device connection to comply with predetermined distances from other components - such as a motor -.
    In order to connect the cable guide 5 safely and splash-tight with the housing body 4, the first end portion 8 of the cable guide 5, a first rigid fastener 11, which may have a hollow cylindrical shape. On an inner side of the first rigid fastening element 11, a first seal 12 is provided, which in an operating state of the system, in which the cable guide 5 is connected to the housing body 4 and the cable 2 is electrically connected to the device connection 3, at a connection part 21 of Housing body 4 rests and surrounds this circumference. In order to achieve a particularly reliable sealing of the joint between the cable guide 5 and the housing body 4, the first seal 12 on its side facing away from the first rigid fastener 11 outside at least one, preferably a plurality of sealing projections 15, which between the first rigid fastener 11 and the connecting part 21st can be clamped and can be designed as sealing rings to surround the connection part 21 of the housing body 4 in the operating state of the system full-scale side. A clear inner diameter of the first rigid fastening element 11 and a clear inner diameter of the preferably likewise hollow cylindrical first seal 12 are matched to the connecting part 21 such that an optimal distribution of that contact pressure can be achieved with which contact pressure the first seal 12 through the fastening element 11 is pressed against the connecting part 21 when the cable guide 5 is connected to the rigid housing body 4.
    The first rigid fastener 11 may be in order to create a secure and reliable connection between
    Cable guide 5 and housing body 4 may be provided with locking elements 22 which can be brought into engagement with the housing body 4 with retaining elements 23 of the connecting part 21 when connecting the cable guide 5 (see FIGS. 2 and 4). Also conceivable are various other locking mechanisms, which serve to fix the relative position between the housing body 4 and cable guide 5. For example, at least one latching element could be provided on the connecting part 21 of the housing body 4, which is provided with at least one retaining element arranged on the first rigid fastening element 11
    Active connection can be brought.
    Analogous to the first end section 8, the second end section 10 of the cable guide 5 also has a second rigid fastening element 13 and a second seal 14. As a result, at least one seal of the connection point between the housing 1 and cable 2 and, moreover, in a preferred embodiment of the invention, a fixation of the penetration depth of the cable end into the cable guide 5 is achieved. In order to accommodate and hold cables 2 different diameter, it may be advantageous if sealing projections 15 of the second seal 14 have a greater amplitude than those of the first seal 12. This allows differences in cable diameters are compensated, provided the clear inner diameter of the second rigid Fastening element 13 is designed such that the - preferably also designed as sealing rings sealing projections 15 of the second seal 14 even when using a cable with a minimum diameter provided still with sufficient contact pressure against the cable 2 - preferably against insulation of the cable 2 - are pressed.
    In this case, the first seal 12 and / or the second seal 14 can be realized by an extension of the bellows whose central longitudinal section forms the central part 9 of the cable guide 5. In this case, an extension of the bellows in the first end portion 8 of the cable guide 5 and another extension of the bellows in the second end portion 10 of the cable guide 5 protrude, so that an extension of the bellows at least partially rigid with the first
    Fastener 11 is brought to coincide and the other extension of the bellows is brought at least partially with the second rigid fastener 13 to cover. In this case, therefore, the first seal 12 and / or the second seal 14 is formed integrally with the bellows. Preferably, the second seal 14 has a higher thickness than the first seal 12.
    The cable lug 7, which is connected to the cable end at a transition 6 between the cable 2 and the cable lug 7, has a contacting element 16 projecting from the transition 6 in the direction of the housing body 4. This contacting element 16 has an opening 24, by means of which the cable lug 7 can be brought into engagement with a fastening bolt 25 of the device connection 3 in order to establish the electrical connection between the cable 2 and the device connection 3.
    A first longitudinal section 17 of the contacting element 16 directly adjoins the transition 6 and closes with a second longitudinal section 18 of the contacting element 16 an angle 19, which can assume a value in the range of 90 ° to 270 °. In the embodiment shown in Fig. 1, the angle 19 is about 200 °.
    The housing body 4 comprises two substantially cylindrical parts, wherein a first cylindrical part 28 has a receiving volume for the fastening bolt 25 of the device connector 3 and a first receiving portion for a cover 26 of the housing body 4 and a second receiving portion for the device port 3. Both the first receiving portion and the second receiving portion of the first cylindrical portion 28 is provided with at least one seal with sealing projections to allow a splash-tight connection between the lid 26 and the device port 3 and the housing body 4.
    A second cylindrical part 29 of the housing body 4 closes in the region of the receiving volume for the fastening bolt 25 to the first cylindrical part 2 8 and has on its side facing away from the receiving volume side, the connecting part 21 of
    Housing body 4 on. This second cylindrical part 29 of the housing body 4 is used exclusively for attaching the cable guide 5 to the housing body 4 and is therefore formed with the shortest possible longitudinal extent. Preferably, the longitudinal extension of the second cylindrical part 29 is smaller than or equal to the longitudinal extension of the second longitudinal section 18 of the contacting element 16 and / or smaller than the diameter of an opening of the connecting part 21 facing the cable guide.
    By means of a screw nut 27, the second longitudinal section 18 of the contacting element 16 can be connected to the fastening bolt 25 and subsequently the connection system to the device connection 3.
    Fig. 2 shows the system of Fig. 1 in a perspective view.
    Fig. 3 shows the system of Fig. 1 and 2, wherein the cable guide 5 is already connected to the housing body 4. The first seal 12 of the first end section 8 of the cable guide 5 encloses at least one longitudinal section of the connecting part 21 of the housing body 4 on the full circumference and is clamped between the connecting part 21 and the first rigid fastening element 11 of the first end section 8 of the cable guide 5.
    In this state, which is also the state in which the system according to the invention is delivered to the customer, the opening 24 of the second longitudinal section 18 of the contacting element 16 is arranged in the receiving volume for the fastening bolt 25 such that the entire connection system according to the invention only on the device connection 3 must be postponed to position the fastening bolt 25 directly in the opening 24 of the contacting element 16 of the cable lug 7 and thus to establish the electrical connection between the cable 2 and device port 3.
    4 shows the connection system from FIG. 3 in a perspective view. In this case, the latching element 22 of the cable guide 5 is brought into engagement with the retaining element 23 arranged on an outer side of the second cylindrical part 2 9 of the housing body 4.
    FIGS. 5 and 6 show the connection system from FIGS. 3 and 4 in an operating state in which the cable 2 is connected to the device connection 3 in an electrically conductive manner. For this purpose, the connection system of Fig. 3 and 4 is placed on the device port 3 and the contacting element 16 is fixed by means of the nut 27 to the mounting bolt 25 of the device port 3.
    By tightening the nut 27 on the one hand, the permanent electrical connection between the cable 2 and device connection 3 ensures and simultaneously pressed the seal of the second receiving portion of the housing body 4 against a conically extending in cross-section outer wall of the device port 3, whereby the desired seal between the housing 1 and device connection 3 takes place. In addition, the cover 26 of the housing body 4 is placed on the first receiving portion of the housing body 4 and fixed to the housing body 4, preferably by means of a bayonet lock. This attachment causes the seal of the first receiving portion is pressed against a cross-section also conically extending sealing surface of the lid 26, whereby the desired sealing of the housing 1 in the region of the lid 26 is achieved.
    In the operating state of the connection system in which the electrical connection between the cable 2 and the device connection 3 is made, the transition 6 is completely arranged within the flexible part 9 of the cable guide 5 which is designed in accordance with the invention. As a result, the cable guide 5 adapts to different cable lugs 7 whose contacting elements 16 each have different angles 19.
    Thus, the same connection housing 1 according to the invention can also be used in conjunction with a cable 2, the cable end is connected, for example by means of the cable lug 7 shown in Fig. 7 with the device port 3. While the angle 19, which the first longitudinal section 17 and the second longitudinal section 18 of the contacting element 16 of this embodiment form with one another, is approximately 180 °, and the cable lug 7 used thus differs from that of the embodiment variant illustrated in FIGS the cable guide 5 due to the positioning of the transition 6 within the flexibly formed middle part 9 and the shape of the cable lug 7 of this embodiment.
    FIG. 9 shows a further embodiment of the connection system according to the invention, wherein the angle 19, which the first longitudinal section 17 and the second longitudinal section 18 enclose, is approximately 225 °. Even at such a cable lug 7, the housing 1, in particular the cable guide 5, easily adapt, since that middle part 9 of the cable guide 5, within which the transition 6 is arranged in the operating state of the connection system, is flexible and therefore relative to the housing body 4 and / or the first end portion 8 is deflected.
    11 again shows another embodiment variant of the connection system according to the invention, wherein the angle 19, which the first longitudinal section 17 and the second longitudinal section 18 enclose, is approximately 135 °.
    Characterized in that the flexible central part 9 of the cable guide 5 relative to the housing body 4 is deflected, the present invention allows the use of the same terminal housing 1 according to the invention in connection with different outgoing directions causing cable shoes 7, wherein the respective cable lugs 7 with respect to their length and angulation of each other can distinguish.
