Description of the Invention: [Technical Field] The present invention relates to a connecting device that electrically connects at least two battery cells (especially high voltage (Hv) cells) via at least two connecting members, such The connecting members each have a contact portion designed to be connectable to battery contacts of the battery cells, and at least partially bridge the battery contacts at least in one of the mounting states of the connecting device The electrical conductors are spaced apart and connected together. Furthermore, the present invention relates to a connecting member of a connecting device which is connectable via a contact portion to a battery contact, the contact portion being designed to be connected to the battery contact and to hold an electrical conductor One of the connection points. · . Furthermore, the invention relates to a battery unit having at least one battery contact. Finally, the invention relates to the use of a contact element for a conductor rod or a backing plate. 70 [Prior Art] In the automotive industry, HV batteries are increasingly used to store the energy of electric vehicle propulsion systems. Since the electric drive requires a large flow in a short time, the t-connecting device between the battery cells must have a conductivity equivalent to that. In addition, the connecting device must compensate for manufacturing tolerances between the battery cells. In addition, when the vehicle vibrates, the connecting device must be able to:: Touch the battery contacts 'that is completely uninterrupted'. Although the physical requirements for the connecting device are high, the connecting device should be easy to install and make the production as cheap as possible. 2156I33.doc 201222941 We actually know the connection means for electrically connecting the battery cells, the connecting parts of the connecting devices, the battery contacts and the contact elements. Usually, the end of the electric mirror connection device has Tightening to the connection parts of the battery contacts. Due to the flexibility of the cable, it ensures the compensation of the manufacturing tolerances of the battery. However, the cable connection is expensive to produce and install. The electric magic can be welded or crimped to the connecting parts, which leads to the production f The use of the increase and the frequent occurrence of faults in the contact area between the cable and the contact element. The "quick lock" system provided by the applicant is called the connection part of the nail to the contact - in place of the m system, the contact element is inserted Plug into a contact (designed as a pin or stub) of an electrical device. In the mounting position the contact element can be flashed to the pin. The yoke is concavely compressed along the cross section. One of the contact members of the contact member for the stub shaft is inserted into the "quick lock" system, and the connecting member or the contact member accommodated therein also has a cable. So far, we have not understood the use of the "quick lock" system in one of the HV battery connectors or battery bridges. SUMMARY OF THE INVENTION In view of the above-discussed deficiencies of the prior art, it is an object of the present invention to provide a reliable connection device for a battery unit that compensates for tolerances and makes handling and production as simple as possible.

For connection components involving the foregoing, the object is achieved such that the electrical conductor is designed as a pin contact by 156133.doc 201222941. In a battery unit relating to the foregoing, the object is achieved such that at least one of the battery contacts is designed to be complementary to at least one of the connecting members of the connecting device according to the invention. For the use of contact elements known per se in the context described above, the contact element is used as a means for displaceably accommodating an electrical conductor (designed as one) in a connection device for electrically connecting two battery contacts Pin connector) - The connection component allows one of the socket contacts to achieve the purpose. The solution according to the invention may be further supplemented and improved as desired by the following additional embodiments which each have their own advantages. In accordance with the invention, the first advantageous embodiment of the connecting device makes it possible to displaceably accommodate the electrical conductor on the connecting part in such a way that the electrical conduction and the connecting component form at least one connection. . For connection. (M cattle may, for example, have connection portions for connecting electrical conductors, etc., which are designed to be fitted together with one of the plug-in members and the mating plug members in one of the spacing directions of the connecting means. The spacing direction may be The direction parallel to the center line of one of the two battery contacts to be coupled, the ', ', or the battery contact. The specific ^ can be at least connected by the connecting portion including the electrical conductor In one simple way, the connection is produced in a simple manner. For this purpose, the connection or the contact element and the electrical conductor are included, for example, to form a body. According to another possible sound of the connection device, V 1 According to the embodiment, at least the group of the connecting member or the connecting portion thereof (as a socket contact) can be one, ra ^. The core connecting component and the electric conductor are easily assembled. For this, one of the connecting ports The connection contact can be configured as a socket contact according to another advantageous embodiment of the connection device. According to another advantageous embodiment of the connection device, at least one of the connection members can have a fastening element by which the at least one connection component can be secured element And locking on one of the battery contacts. For example, the secure element can be a push-bolt or a latching element that can engage one of the bolting or flash lock auxiliary devices on the battery contacts. Alternatively, the connecting device can be non-detachably and detachably fastened to the battery in a simple manner. At least m of the connecting member has a secure element engageable with at least one of the electrical points and at least in a secure state of the connecting member or the connecting device Medium (in one projection along the connection direction of the connection device) may at least partially overlap with the respective battery contact. According to another possible embodiment, the connection "production" can better compensate for tolerances and compensate for beta vibrations such that at least The mounting & middle conductance system is guided in an elastically movable manner. According to another advantageous embodiment, it is possible to simply "form (4) == move and hold" so that at least in the mounted state - at least the spring member Disposed at least between the electrical conductor and the connecting portion to at least one of the connecting members and the respective battery contacts and/or the respective battery contacts are elastically movable The type of holding 2>--connecting parts is divided. Therefore, the electrical conductor or the connection/set-current transmission line part compensates for tolerance and compensation _ installation and allows for a fixed resistance value. Vibration, which means continuous The contact has a blame 156133.doc 201222941 According to another possible embodiment, the electrical portion can be protected from contact' such that the straps are connected at the respective devices and the housing is duplicated. The female dressing state can be implemented in a simple manner. Positioning the two to each other. Therefore, the housings can be compensated for tolerances relative to each other. The device is sealed, but the solution according to the invention is still improved with respect to the connecting parts of the foregoing, == a first pass One of the connecting members of the connecting member is connected to the real part of the connecting member (4), and the connecting portion of the connecting member is perpendicular to the staggering direction specified by the connecting portion. The winding direction of the winding roll can be extended parallel to the direction between the connecting devices. Therefore, the or-electric conductors are connected to the battery contacts to some extent; the holding-battery contacts are displaceably held, whereby (the "bridge direction is poor". In this case, if the contact portion is set It is advantageous to compensate for the public. Therefore, the connecting member can be easily plugged into the battery contact of a pin contact. The connecting member can be easily and quickly installed by plugging the connecting member to electricity: == Including one of the connecting members, a mounting method is conceivable in which the connecting portion of the connecting member can be connected in a conductor to connect the two battery elements, and in each case the L-part of the device (which is combined with the connecting portion - The start-up = connection to the respective battery contact 'and in each case the connection portion of the conductance system relative to i is at least displaceably accommodated in at least one of the connection portions in the spacing direction. 156133.doc 201222941 [Embodiment] The invention is explained in more detail by way of example with reference to several embodiments of the accompanying drawings, which illustrate only possible configurations in which individual features as described above can be taken and omitted independently of one another In the description of the embodiments, the same features and elements have the same element symbols for the sake of simplicity.

In each case, the connecting members 2, 2b each have a first contact portion outside the second contact portion and each have a first connection The connecting portion 4a and the second connecting portion can be connected via the contact portions 3a, 3b in the connecting direction Z, and the hole is plugged to the battery contact HH. At the connecting portion 4a' 4b, the connecting member h, 沘They can be assembled together in the spacing direction X. An electrical conductor 5 protrudes from the plug portion 6b of one of the second connecting member holes in the spacing direction X. The plug portion 6b is formed to be one with the first connecting member 156133 .doc -10- 201222941 Socket core filler material 2a forms a plug element 7a in the connecting portion 且 and the second connecting member 21) forms a mating plug element 7b in the connecting portion. In addition, the 1-connecting member 2a The contact ^3a is designed to be capable of bonding the battery contacts 101 to the secure element 83. Similarly, the contact portion 3b of the second connecting member 2b is provided with a securing member 8b designed to be engageable with the battery contact (8). Fig. 3 shows the connecting device 处于 in an assembled state B in which the mating plug member 7b is broken into the plug member, so that the plug member 7b is no longer visible from the outside. It is prepared to push the connecting device 1 in the assembled state 8 to the battery contact 1 0 1 in the connecting direction 2. The battery contact 101 protrudes from the battery unit 沿 in the opposite direction to the connecting direction Z and has a cylindrical cross section. In the transition between the peripheral surface 1 〇 2 of one of the battery contacts 1 〇 1 and the end face 1 〇 3, the battery contact 1 具有 1 has a plug 1 for facilitating the plugging of the connecting device 1 to the battery contact 101 〇 4. A plate-shaped fastening aid D is further provided with a 〇 5 projecting from the end face 103 of the battery contact 1 〇 1 in the opposite direction of the connecting direction z and designed to cooperate with the fastening member 8a and the rib. Fig. 4 shows the connecting device 1 in the mounted state c, wherein the connecting device 1 is plugged onto the battery contact 101 and spans an interval X1 之间 between the battery cells 100 which can be varied according to respective manufacturing tolerances. Fig. 5 shows the connecting device 1 shown in Fig. 4 along the section line d_d shown in Fig. 4 in the mounted state c. The connecting member 2a includes a contact member 9a' which forms a hollow cylindrical battery contact socket l〇a in the contact portion 3a. One of the cylindrical spring members 丨i is folded along the cross section and is 156133.doc 201222941 placed in the battery contact socket 1 〇a. The spring member 11 in the battery contact socket i〇a of the contact portion 3a is elastically movable to secure the battery contact 丨〇1' in the spacing direction X and in the lateral direction γ and is displaceably movable in the connecting direction Z Firm battery contact 101. Therefore, the spring member j i in the battery contact jack 1 促a contributes to the compensation of the tolerances in the spacing direction X, the lateral direction γ, and the connecting direction Z. The contact member 9a forms one of the connection portions 12a of the connecting portion 4a of the connecting member 2a. One of the socket contacts is connected to the contact socket 13a (in which another spring member 11 is disposed) formed on the connection contact i h . In addition, the spring member i丨 (which is also cylindrical and concavely constricted in cross section) encloses the electrical conductor 5, so that in the connecting portion 4a of the connecting member 2a, the electric conductor 5 is displaceably displaced in the spacing direction It is accommodated and accommodated in a laterally movable direction γ and a connecting direction 以 in an elastically movable manner. The electric conductor 5 is formed as a connection plug contact 13b or a pin contact which is formed on one of the connection contacts ib of one of the coupling members 2b. A battery contact socket l〇b (which is also a hollow cylindrical shape) is formed on the mating contact member 9b. Another spring member u, which is cylindrical and concave in both directions in cross section, is disposed in the battery contact socket 1b, which radially engages around the battery contact 1〇1 on the inner side thereof and is Supported radially outward in the battery contact socket l〇b. Due to the arrangement of the contact elements 9a and the mating contact elements shown in Figure 5, the electrical conductors 5 at least partially bridge the gap between the centerline rivers of the battery contacts 1〇1. In the respective contact sockets 1a, i〇b or 13a, the battery contacts 101 are displaceably held in the connecting direction 2, and are designed as a plug-in I56I33.doc 12 201222941 pin contacts are connected The electric conductor 5 in the form of the plug contact 13b is displaceably held in the spacing direction X. The compensation of the tolerance is ensured by the displaceable holding, and the spring member 11 compensates for the tolerance and compensates for the respective contacts 1〇1 and 13b. Vibration caused by elastic engagement around. In addition, the spring members 11 of the respective contact sockets 〇, i, b and 13a elastically introduce the contact force to the battery contact socket 10a by the contact elements % or the connection contacts 14a, 14b outside the contact elements. , 10b. Therefore, the spring member 11 not only performs a mechanical support and sliding function, but also forms part of a current transmission path via the spring element 1 in the battery contact socket 10a, via the contact element, in the connection contact socket 13a The spring element u, the connection plug contact nb 'the electric conductor $, the spring member disposed in the battery contact socket 10b, and the battery contact i Q i accommodated in the battery contact socket 10 a are connected to the battery Between the battery contacts 1 〇1 in the point socket i 〇b. Further, the contact member 9a and the mating contact member are housed in a casing 15a or 15b, respectively. The @body 15a forms the socket 6ae and the housing 15b forms the plug portion 6b. In the assembled state B and in the mounted state c of the connection, the socket 6a and the plug portion 6b form an overlap region 16, wherein the casing ... and (5) are partially displaced in the connecting direction ZfM. Therefore, the housings ... and _ are first compensated for tolerances in the spacing direction and then protected from contact by sealing all of the live parts (i.e., the battery contacts 101 and the contact elements % and the mating contact elements 9b). In addition, it is clearly shown in FIG. 5 that in each case, the fastening element is displaceably held in the spacing direction X and guided in the holes of the housing (5) and the i56133.doc -13 - 201222941 - respectively. In piece m or (7). In each case, the secure elements 8a, 8b have access elements 18a and 18b. The splicing element core, (10) is designed to engage one of the battery contacts 1 〇 1 of the battery-shaped contact auxiliary device 1 〇 5 and the end surface 103 of the battery contact 101. The secure element 8a is in an unplugged position u in which the secure element 8a is disengaged from the weighted bar 1 〇6. One of the engagement profiles 19a of the bolting element 1 of the secure element 8a is designed to complement the cylindrical shank 1 〇 7 of one of the battery contacts 101 holding the secure auxiliary device 1〇5. The bolting element 8b is in a bolted position 1 in which the bolting element 8b engages the bolted socket 1〇6. Therefore, the invisible joint profile 19b on the bolting element i8b of the secure element at least partially encloses the shank 1〇7 between the end face 1〇3 of the battery contact 1〇1 and the secure auxiliary device 105, and thus ensures The fastening element 8b and the fastening aid 105 are in one of the projections in the opposite direction of the connecting direction B or the fastening element 8b and the end face 103 are overlapped in the maximum possible area in one of the projections in the connecting direction z. This ensures that the connecting device is firmly held on the battery contact 且 且 and the connecting device 1 is non-detachably held on the battery contact 1 〇 1 'but the blade is parallel to the connection direction Z measured by the bolted socket 1 One of the heights of the crucible 6 is such that it exceeds the height of one of the inspection elements 18 a, 18b measured in the connection direction Z and thus allows a certain gap to be present, which promotes the compensation of the tolerances in the connection direction Z. Deviations from the above embodiments may fall within the scope of the invention. Therefore, the connecting portions 4a, 4b do not necessarily have a socket 6a or a plug portion 6b as long as the connecting members 2a, 2b can be advantageously assembled. The electrical conductor 5 is not necessarily integral with the mating contact element 9b. Alternatively, for example, 156133.doc 24 201222941 uses a pin or stub shaft as an electrical conductor 5 that is displaceably held in two connection contact sockets 13a that open toward each other, In each case, the connection contact socket 13a is provided by a contact element 9a or can be accommodated in a displaceable manner without a plug mechanism. The connection contacts 14a, 14b do not necessarily have a battery contact socket I〇a or lb, respectively, but can be designed, for example, as pin contacts, which can be designed to be plugged to correspond It is designed as a battery contact 101 for the pin contact jack. Moreover, the battery contacts J i and the battery contact sockets 1 〇a, ^ (10) may have other alternatives as long as they are designed to complement each other and allow for compensation and along the connection direction of the connecting members 2 & and 2b It can be installed in a displaceable manner. It is also conceivable to latch or pin the connecting parts 2&, 2b to the battery contacts ι〇ι in place of the bolting of the auxiliary devices of the splicing elements 18a, 18b. In each case, the housings 15a, 15b are designed so as not to enclose the contact element % or the mating contact 70 piece 9b, but may be composed of a plurality of parts. Thus, for example, it is contemplated that a contact protection is achieved by at least partially encapsulating the contact elements.
