Description
Connector busbar connection structure Technical Field
[0001] This invention relates to the technical field of components for conductive connection devices, and more particularly to connector busbar connection structures. Background Technology
[0002] In new energy vehicles, connectors are frequently required to establish power connections between cables and equipment. Existing implementations, as shown in Figures 1-3, typically involve mounting a socket 3 on the equipment panel 1. The socket 3 includes a socket housing 30 fixed to the equipment panel 1 by mounting bolts. The socket housing 30 has an inner housing 31 extending through a through-hole into the inside of the equipment panel 1. An insulating component 32 is installed within the inner housing 31, and the socket's contact is installed within the insulating component 32. The outer end of the contact is located within the socket housing 30, and the inner end is located inside the equipment panel 1. The inner end of the contact is fixedly connected to a busbar 2 inside the equipment by connecting bolts. A plug 4 is inserted into the socket 3, and the contacts of the plug 4 are electrically connected to the contacts of the socket 3, achieving conductivity with the busbar 2.
[0003] In traditional connector-busbar connection structures, the socket contacts are connected to the busbar via bolts. This is not only inconvenient but also requires reserved operating space within the equipment, which imposes certain requirements on the equipment's size and hinders miniaturization. Furthermore, when the socket malfunctions and requires repair, the equipment casing must be opened, the bolts removed to separate the busbar and socket contacts, and only then can the socket be detached from the equipment panel. This process is cumbersome and inefficient. Summary of the Invention
[0004] The purpose of this invention is to provide a connector busbar connection structure to solve the problem that the existing connection method between the connector and the busbar in the equipment is not conducive to the disassembly and maintenance of the connector in the later stage.
[0005] The connector busbar connection structure of the present invention includes a socket for mounting on a device panel. The socket includes a socket housing and a contact element mounted inside the socket housing. One end of the contact element facing the inside of the device panel has a busbar connection structure, which is a mating structure for plugging into a busbar.
[0006] Furthermore, the insulating component installed inside the socket housing is provided with an elastic snap-fit structure for hooking and engaging with the busbar. The insulating component has an extension section that extends beyond the busbar connection structure in the direction toward the busbar. The inner cavity of the extension section allows the busbar to extend into and engage with the busbar connection structure. The elastic snap-fit structure is provided on the extension section.
[0007] Furthermore, the elastic snap-fit structure is located at a position corresponding to the edge of the busbar in the width direction, so as to hook and engage with the edge of the busbar in the width direction.
[0008] Furthermore, the elastic snap-fit structure is located at a position corresponding to the side of the busbar in the thickness direction, so as to hook and cooperate with the side of the busbar. Furthermore, the elastic snap-fit structure is an elastic hook facing the busbar, and the busbar is provided with a snap-fit groove.
[0009] Furthermore, the extension section is provided with the aforementioned elastic snap-fit structure at positions corresponding to the two edges in the width direction of the busbar, and the two edges in the width direction of the busbar are hooked and engaged with the elastic snap-fit structure.
[0010] Furthermore, the outer end face of the hook claw of the elastic hook and / or the edge of the front end face of the busbar corresponding to the elastic hook are provided with guide bevels to facilitate the insertion of the busbar.
[0011] Furthermore, the inner end face of the hook claw of the elastic hook and / or the groove wall that mates with the inner end face of the hook claw are sliding slopes, so that the busbar can be forcibly separated from the elastic locking structure under the action of external pull-out force.
[0012] Furthermore, a resilient latch is located on the inner wall of one end of the extension section facing away from the socket housing.
[0013] Furthermore, the mating structure is a clip-type mating structure.
[0014] The connector busbar connection structure of this invention is an invention with modified elements. By setting the conductive connection between the busbar and the socket contact in a plug-in connection, compared with the existing connection bolt connection, it is not necessary to connect the socket contact and the busbar separately when installing the socket, which simplifies the installation process. At the same time, it is not necessary to reserve operating space inside the equipment, which helps to realize the miniaturization of the equipment. When disassembling the socket, it is not necessary to disassemble the socket contact and the busbar separately. Simply remove the mounting bolts of the socket, and the socket can be directly pulled out from the equipment panel. The socket is more convenient for later maintenance and replacement.

[0017] The features and performance of the present invention will be further described in detail below with reference to embodiments.
[0018] The connector busbar connection structure of the present invention uses a plug-in conductive method to connect the internal busbar of the device to the socket contact of the socket installed on the device panel. When the socket is installed on the device panel, the socket contact can be directly plugged into the busbar. When the socket is removed from the device panel, the socket contact can be directly pulled out from the busbar, which greatly reduces the difficulty of disassembly and assembly and facilitates the later maintenance and replacement of the socket.
[0019] Based on the above concept, the present invention provides embodiments of various connector busbar connection structures for illustration.
[0020] In a basic embodiment, as shown in Figures 4, 6, and 7, the connector busbar connection structure includes a socket 3 mounted on the device panel 1 and a busbar 2 installed inside the device housing and located on the inner side of the device panel 1. The socket 3 includes a socket housing 30, the edge of which is fitted with mounting bolts. The device panel 1 has mounting holes, and the socket housing 30 is fixedly mounted on the device panel 1 by the mounting bolts. The portion of the socket housing 30 located on the outer side of the device panel 1 is the same as the existing socket housing 30 structure. The inner housing 31 of the socket housing 30 is also the same as in the prior art, extending into the inner side of the device panel 1 through the through-hole on the device panel 1, which will not be described in detail in this embodiment. The difference is that the socket contact 5 installed in the inner housing 31 has a plug-in connection structure at the end facing the busbar 2, which is a plug-in connection structure with the busbar 2. As can be clearly seen from Figure 7, the socket contact 5 in this embodiment has a central fixing section 51 for assembly with the socket housing 30, and both ends are clip-type plug-in structures 50, that is, one end is plugged into the plug contact 41 for conduction, and the other end is plugged into the busbar 2 for conduction. The clip-type plug-in structure 50 is a commonly used plug-in structure in the prior art, and its structure will not be described in detail here. In different embodiments, the way the socket contact 5 is connected to the plug contact 41 can vary, as long as the busbar connection structure connecting the socket contact 5 to the busbar 2 is a plug-in structure.
[0021] Based on the above embodiments, in one embodiment, the inner housing 31 extends beyond the insertion structure in the direction towards the busbar 2, that is, the entire insertion structure is located inside the inner housing 31. The insulating component 32 installed inside the inner housing 31 has an extension section extending beyond the insertion structure in the direction towards the busbar 2. The inner cavity of the extension section allows the busbar 2 to extend into and insert with the busbar connection structure. The extension section is provided with an elastic snap-fit structure, which is hooked to the busbar 2. In this scheme, by means of the elastic deformation of the elastic snap-fit structure, the busbar 2 can be inserted into the inner cavity of the extension section and inserted with the insertion structure of the socket contact 5. At the same time, the hook-fit connection between the elastic snap-fit structure and the busbar 2 can ensure that the busbar 2 and the socket contact 5 are not dislodged in the insertion direction when the equipment is in normal use. When the socket 3 malfunctions and needs to be disassembled for maintenance, after removing the mounting bolts, the socket housing 30 can be pulled by external force to overcome the elastic holding force of the elastic snap-fit structure, release the hook-fit connection between the elastic snap-fit structure and the busbar 2, thereby facilitating the disassembly of the socket 3. Of course, in some embodiments, a hook connection structure may not be provided between the socket 3 and the busbar 2, especially when the busbar 2 is already fixedly connected inside the equipment. For example, based on the prior art shown in Figure 3, an insertion structure is provided at the end of the socket contact 5 that extends out of the socket housing 30, and the socket contact 5 is directly inserted and connected to the busbar 2 through the insertion structure.
[0022] Based on the above embodiments, there are different implementation methods for the specific arrangement of the elastic snap-fit structure. In one embodiment, the side surface of the busbar 2 in the thickness direction, i.e., the plate surface, is provided with a protruding ridge extending in the width direction. The insulating component 32 is provided with an elastic arm at a position corresponding to the protruding ridge, and the elastic arm is provided with a hook groove adapted to the protruding ridge. When the busbar 2 is inserted into the insertion structure, the protruding ridge snaps into the hook groove. Alternatively, in another embodiment, the elastic snap-fit structure is provided at a position corresponding to the edge of the busbar 2 in the width direction, so as to hook and engage with the edge of the busbar 2 in the width direction. Since the width of the busbar 2 is larger than its thickness, setting the elastic snap-fit structure here can increase the depth of the hook engagement between the busbar 2 and the elastic snap-fit structure without changing the size of the busbar 2, thereby improving reliability. Based on this, in one embodiment, a barb structure can be provided on the edge of the busbar 2 in the width direction, and an elastic arm is provided on the insulating component 32. The elastic arm has a hook groove. When the busbar 2 is inserted, the barb structure pushes the elastic arm to deform and avoid the barb structure. When the barb structure moves to the position corresponding to the hook groove, the elastic arm resets and the hook groove hooks onto the barb structure. In the embodiment shown in Figures 4-5, the elastic snap-fit structure is an elastic snap hook 33 provided on the insulating component 32 facing the busbar 2. The edge of the busbar 2 in the width direction has a slot 20. After the busbar 2 and the socket contact 5 are inserted into place, the elastic snap hook 33 is snapped into the slot 20 and hooked to the busbar 2. Specifically, in one embodiment, an elastic cantilever extends from the end face of the insulating component 32 facing the busbar 2. The end of the elastic cantilever has a claw, thereby forming the elastic snap hook 33. In the embodiment shown in Figure 5, a groove is provided on the inner wall of the end of the extension section facing the busbar 2, and an elastic cantilever is provided on the inner wall of the extension section, extending into the groove. The end of the elastic cantilever has a hook, thereby forming the elastic hook 33. This arrangement of the elastic hook 33 within the extension section provides a certain degree of protection.
[0023] Based on the above embodiments, in one embodiment, the elastic snap-fit structure is only provided at the position corresponding to one side edge of the busbar 2 in the width direction. In another embodiment, the elastic snap-fit structure is provided at the positions corresponding to both sides edge of the busbar 2 in the width direction, so that the hooking force on the busbar 2 is symmetrical.
[0024] Based on the above embodiments, in a more preferred embodiment, in order to facilitate the insertion of the busbar 2, the outer end face of the hook claw of the elastic hook 33 and / or the edge of the front end face of the busbar 2 corresponding to the elastic hook 33 are provided with a guiding slope; in order to facilitate the disengagement of the busbar 2 from the socket contact member 5, the inner end face of the hook claw of the elastic hook 33 and / or the groove wall of the slot 20 that cooperates with the inner end face of the hook claw is a sliding slope.
[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
