[0001] The present invention relates to the technical field of parts for conductive connection devices, and in particular to a connector busbar connection structure. Background Art

[0002] Connectors are often needed in new energy vehicles to achieve power supply connections between cables and devices. Existing implementation methods include Figure 1-3 As shown, a socket 3 is often installed on the device panel 1. The socket 3 includes a socket housing 30 fixedly connected to the device panel 1 by mounting bolts. The socket housing 30 has an inner housing 31 that passes through the through-hole on the device panel 1 and extends into the inner side of the device panel 1. An insulating component 32 is installed in the inner housing 31, and the contact of the socket is installed in the insulating component 32. The outer end of the contact is in the socket housing 30, and the inner end is in the inner side of the device panel 1. The inner end of the contact is fixedly connected to the busbar 2 in the device by connecting bolts. The plug 4 is plugged and connected to the socket 3, and the contact of the plug 4 is conductively connected to the contact of the socket 3, and realizes conduction with the busbar 2.

[0003] In the traditional connection structure between the connector and the busbar, the socket contact and the busbar are connected by connecting bolts, which is not only inconvenient to connect, but also requires a certain amount of operating space to be reserved in the device, which puts certain requirements on the size of the device and is not conducive to the miniaturization of the device. In addition, when the socket fails and needs to be repaired, it is necessary to open the housing of the device, remove the connecting bolts to separate the busbar and the socket contact, and then remove the socket from the device panel. The operation process is cumbersome and inefficient. Summary of the invention

[0004] The object of the present 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 subsequent disassembly and maintenance of the connector.

[0005] The connector busbar connection structure of the present invention includes a socket for installation on a device panel, the socket includes a socket shell and a contact installed in the socket shell, the end of the contact facing the inner side of the device panel has a busbar connection structure, and the busbar connection structure is an insertion structure for plugging connection with a busbar.

[0006] Furthermore, an insulating component installed in the socket housing is provided with an elastic snap-fit ​​structure for hooking with the busbar, and the insulating component has an extension section that extends beyond the busbar connection structure in the direction toward the busbar, and the inner cavity of the extension section is for the busbar to extend into and be plugged into the busbar connection structure, and the elastic snap-fit ​​structure is arranged on the extension section.

[0007] Furthermore, the elastic snap-fit ​​structure is arranged at a position corresponding to the edge of the busbar in the width direction, so as to be hooked and matched with the edge of the busbar in the width direction.

[0008] Furthermore, the elastic snap-fit ​​structure is arranged at a position corresponding to the side surface of the busbar in the thickness direction, so as to be hooked and matched with the side surface of the busbar. Furthermore, the elastic clamping structure is an elastic clamping hook arranged toward the busbar, and a clamping groove is provided on the busbar.

[0009] Furthermore, the elastic snap-fitting structures are provided on the extension section 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 matched with the elastic snap-fitting structures.

[0010] Furthermore, the outer end surface of the claw of the elastic hook and / or the edge of the front end surface of the busbar corresponding to the elastic hook is provided with a guiding inclined surface to facilitate the insertion of the busbar.

[0011] Furthermore, the inner end surface of the claw of the elastic hook and / or the groove wall of the groove cooperating with the inner end surface of the claw is a slip-off inclined surface, so that the busbar is forcibly separated from the elastic snap-fit ​​structure under the action of an external pulling force.

[0012] Furthermore, the elastic hook is arranged on the inner wall of the end of the extension section facing away from the socket housing.

[0013] Furthermore, the plug-in structure is a clip-type plug-in structure.

[0014] The connector busbar connection structure of the present invention is an invention of element change type. By setting a conductive connection method of plug-in connection between the busbar and the socket contact, compared with the existing connection bolt connection, there is no need to separately connect the socket contact and the busbar when installing the socket, which simplifies the installation process. At the same time, there is no need to reserve operating space inside the equipment, which helps to achieve miniaturization of the equipment. When disassembling the socket, there is no need to separately disassemble the socket contact and the busbar. Only the mounting bolts of the socket need to be removed to directly pull the socket out of the equipment panel, which makes it more convenient to repair and replace the socket later.

[0017] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0018] The connector busbar connection structure of the present invention is a conductive method of plug-in connection between the busbar inside the device and the socket contact of the socket installed on the device panel, so that when the socket is installed on the device panel, the socket contact and the busbar can be directly plugged in. When the socket is removed from the device panel, the socket contact and the busbar can be directly pulled apart, thereby greatly reducing the difficulty of disassembly and assembly, and facilitating the later maintenance and replacement of the socket.

[0019] Based on the above concept, the present invention provides various embodiments of connector busbar connection structures for illustration.

[0020] In a more basic embodiment, Figure 4 , 6 As shown in Figures 7 and 8, the connector busbar connection structure includes a socket 3 installed on the equipment panel 1 and a busbar 2 installed in the equipment housing and located on the inner side of the equipment panel 1. The socket 3 includes a socket housing 30. The edge of the socket housing 30 is equipped with mounting bolts. The equipment panel 1 is provided with mounting holes. The socket housing 30 is fixedly mounted on the equipment panel 1 by mounting bolts. The portion of the socket housing 30 located on the outer side of the equipment panel 1 is the same as the structure of the existing socket housing 30. The inner housing 31 of the socket housing 30 is the same as the prior art. It also extends into the inner side of the equipment panel 1 through the through hole on the equipment panel 1, which will not be described in detail in this embodiment. The difference is that the busbar connection structure of the socket contact 5 installed in the inner housing 31 at the end facing the busbar 2 is a plug-in structure for plug-in connection with the busbar 2. From Figure 7It can be clearly seen that the socket contact 5 in this embodiment has a middle fixed 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 and connected with the plug contact 41, and the other end is plugged and connected with the busbar 2. The clip-type plug-in structure 50 is a commonly used plug-in structure in the prior art, and its structure is not described in detail in this article. In different embodiments, the way the socket contact 5 is connected to the plug contact 41 can be changed, as long as the busbar connection structure of the socket contact 5 connected to the busbar 2 is a plug-in structure.

[0021] On the basis of the above embodiments, in one embodiment, the inner housing 31 exceeds the plug-in structure in the direction toward the busbar 2, that is, the plug-in structure is entirely inside the inner housing 31, and the insulating component 32 installed in the inner housing 31 has an extension section that exceeds the plug-in structure in the direction toward the busbar 2, the inner cavity of the extension section is for the busbar 2 to extend into and plug with the busbar connection structure, and an elastic clamping structure is provided on the extension section, and the elastic clamping structure is hooked and connected with the busbar 2. In this scheme, by means of the elastic deformation of the elastic clamping structure, it is ensured that the busbar 2 can be inserted into the inner cavity of the extension section and plugged with the plug-in structure of the socket contact 5, and at the same time, the hooking connection between the elastic clamping structure and the busbar 2 can ensure that the busbar 2 and the socket contact 5 are prevented from falling off in the plugging direction when the equipment is in normal use, and when the socket 3 fails and needs to be disassembled and repaired, after the mounting bolts are removed, the socket housing 30 is pulled out by external force, which can overcome the elastic retaining force of the elastic clamping structure and release the hooking connection between the elastic clamping structure and the busbar 2, thereby facilitating the disassembly of the socket 3. Of course, in some embodiments, no hook connection structure may be provided between the socket 3 and the busbar 2, especially when the busbar 2 is already fixedly connected inside the device. Figure 3 On the basis of the prior art shown, an inserting structure is provided at the end of the socket contact 5 extending out of the socket housing 30 , and is directly plugged and connected to the busbar 2 via the inserting structure.

[0022] On the basis of the above-mentioned embodiments, there are different implementations for the specific setting of the elastic snap-fit ​​structure. In one implementation, the side surface in the thickness direction of the busbar 2, that is, the plate surface, is provided with a ridge extending in the width direction, and an elastic arm is provided on the insulating component 32 at a position corresponding to the ridge, and a hooking groove adapted to the ridge is provided on the elastic arm. When the busbar 2 is inserted into the plug-in structure, the ridge is snapped into the hooking groove. Or in one implementation, the elastic snap-fit ​​structure is provided at a position corresponding to the edge in the width direction of the busbar 2 to hook and cooperate with the edge in the width direction of the busbar 2. Since the width of the busbar 2 is larger than the thickness of the busbar 2, the elastic snap-fit ​​structure is provided here, which can increase the depth of the hooking and cooperation between the busbar 2 and the elastic snap-fit ​​structure without changing the size of the busbar 2, thereby improving reliability. On this basis, in one embodiment, a barb structure can be provided at the edge of the busbar 2 in the width direction, an elastic arm can be provided on the insulating component 32, and a hook groove can be provided on the elastic arm. When the busbar 2 is inserted, the barb structure pushes the elastic arm to deform to avoid the barb structure. When the barb structure moves to a position corresponding to the hook groove, the elastic arm is reset to make the hook groove hook on the barb structure. Figure 4-5 In the embodiment shown, the elastic snap-fit ​​structure is an elastic snap-fitting structure 33 disposed on the insulating component 32 and disposed toward the busbar 2. A snap-fitting slot 20 is disposed at the edge of the busbar 2 in the width direction. After the busbar 2 and the socket contact 5 are plugged into place, the elastic snap-fitting hook 33 snaps into the snap-fitting slot 20 and is hooked and connected to the busbar 2. Specifically, in one embodiment, an elastic cantilever extends from the end face of the insulating component 32 on the side facing the busbar 2, and the end of the elastic cantilever has a hook claw, thereby forming the elastic snap-fitting hook 33. In the embodiment shown in FIG. Figure 5 In the embodiment shown, a groove is provided on the inner cavity 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, which is cantilevered into the groove, and a claw is provided at the end of the elastic cantilever, thereby forming the elastic hook 33. In this way, the elastic hook 33 is arranged in the extension section, which can play a certain protective effect on the elastic hook 33.

[0023] On the basis of the above embodiments, in one embodiment, the elastic snap-in structure is only arranged at a position corresponding to one side edge of the busbar 2 in the width direction. In another embodiment, the elastic snap-in structure is arranged at positions corresponding to both side edges in the width direction of the busbar 2, so that the hooking force acting on the busbar 2 can be symmetrical.

[0024] On the basis of the above embodiments, in a more preferred embodiment, in order to facilitate the insertion of the busbar 2, the outer end surface of the claw of the elastic hook 33 and / or the edge of the front end surface of the busbar 2 corresponding to the elastic hook 33 are provided with a guiding bevel; in order to facilitate the separation of the busbar 2 from the socket contact 5, the inner end surface of the claw of the elastic hook 33 and / or the groove wall of the groove 20 that cooperates with the inner end surface of the claw are provided with a sliding bevel.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
