[0022] The features and performance of the utility model are further described in detail in the following combined with the embodiment.

[0023] The utility model's connector busbar connection structure changes the traditional design idea, and the contact piece in the traditional socket is omitted, one end of the busbar fixedly installed in the device plays the role of the socket contact piece, the busbar accommodating cavity is arranged in the socket shell, one end of the busbar fixedly installed in the device can be inserted into the busbar mounting cavity, and the conductive connection end that is in contact with the contact piece of the adaptive plug is formed, when the socket shell is installed on the device panel, one end of the busbar is inserted into the busbar accommodating cavity, when the socket shell is removed from the device panel, the end of the busbar is withdrawn from the busbar accommodating cavity, and the dismounting and maintenance of the connector are more convenient.

[0024] Based on the above idea, the following provides various embodiments of the connector busbar connection structure for illustration.

[0025] In a more basic embodiment, as Figures 4-5As shown, the connector female busbar 2 connecting structure comprises a socket shell 3 and a female busbar 2 fixedly installed in the equipment. The socket shell 3 is fixedly installed on the equipment panel 1 by mounting bolts and is provided with an adapter plug 4. The relevant structure of the socket shell 3 is the same as that of the socket shell 3 introduced in the background art, and will not be described in detail in this embodiment. Like the prior art, the socket shell 3 also has a receiving cavity for accommodating a conductor in conductive communication with the contact of the adapter plug 4, but unlike the prior art, the receiving cavity is a female busbar 2 receiving cavity. The female busbar 2 receiving cavity has an opening towards the inside of the equipment panel 1, which forms an access passage for the end of the female busbar 2 to enter and exit the female busbar 2 receiving cavity. When the socket shell 3 is installed on the equipment panel 1, the end of the female busbar 2 is inserted into the female busbar 2 receiving cavity from the opening and forms a conductive connection end 20 for contact communication with the contact of the adapter plug 4. When the socket shell 3 is removed from the equipment panel 1, the end of the female busbar 2 exits the female busbar 2 receiving cavity from the opening. In this way, when the socket is inserted and maintained, it is not necessary to contact the connection between the socket and the female busbar 2 as in the prior art, and the disassembly and maintenance of the connector is more convenient.

[0026] On the basis of the above-mentioned embodiments, the conductive communication between the conductive connection end 20 and the contact of the adapter plug 4 can be different in different embodiments. For example, in one embodiment, the conductive connection end 20 is the side of one end of the main body of the female busbar 2, and the cavity wall of the female busbar 2 receiving cavity is provided with a relief gap for the conductive connection end 20 to protrude. When the adapter plug 4 is inserted into the socket shell, the contact of the adapter plug 4 extends into the relief gap and is in contact with the side of the female busbar 2 for conductive communication. In order to ensure reliable contact, a wire pressing screw can be provided to lock and connect the two together. In one embodiment, the conductive communication between the conductive connection end 20 and the contact of the adapter plug 4 is achieved by plug-in contact, for example, one of them is a contact spring arm structure, and after they are plugged together, the contact spring arm structure ensures reliable conductive communication between them. At this time, the female busbar 2 receiving cavity is provided with a plug-in opening on the side opposite to the opening, and the conductive connection end 20 is a contact spring arm provided at the end of the main body of the female busbar 2. The contact spring arm is inside the female busbar 2 receiving cavity and opposite to the plug-in opening. The plug-in opening is for the contact of the adapter plug 4 to be inserted and in contact with the conductive connection end 20. Alternatively, in a similar embodiment, the conductive connection end 20 is a conductive jack structure for the conductive pin of the adapter plug 4 to be inserted.

[0027] In one embodiment, the front end of the main body of the female busbar 2 is fixedly provided with a sheet contact, which constitutes the conductive connection end 20 and is used for plug-in conductive communication with the contact of the adapter plug 4. This structure is similar to the structure of the socket contact in the prior art, and the existing parts can be used universally, minimizing changes to the existing structure and reducing manufacturing costs.

[0028] In an embodiment, in order to ensure the reliable insertion of the socket and the adapter plug 4, the sheet contact is a clamping sheet contact, and the insertion space 23 for the contact of the adapter plug 4 is formed between the opposite clamping sheets 22 and is opposite to the insertion port. The clamping sheet contact is common in the prior art, such as the contact disclosed in the Chinese Utility Model Patent Application with the application publication number CN111564720A or CN116031683A. In the utility model, in order to adapt to the connection between the main body of the busbar 2, in an embodiment, as shown in Figure 6 CN116031683A, the main body is arranged in pairs and fixed together, the end portions of the main body are opposite to each other and form elastic overhanging sections 200, and the space between the two elastic overhanging sections 200 constitutes the insertion space 23. In another embodiment, as shown in Figure 7 CN111564720A, the fixed ends of the two clamping sheets 22 are respectively connected to the two side surfaces of the main body, and the insertion space 23 is formed between the elastic overhanging sections 200 of the two clamping sheets 22. When this mode is adopted, the end portion of the main body is preferably provided with a connecting notch 21 on each side surface, the fixed end of the clamping sheet 22 is respectively inserted into the connecting notch 21 and is welded and fixedly connected to the main body, the insertion space 23 is formed between the overhanging sections of the two clamping sheets 22, the depth of the connecting notch 21 is equal to the thickness of the clamping sheet 22, and the outer side surface of the clamping sheet 22 is flush with the side surface of the main body.

[0029] In addition, similar to the prior art, the busbar 2 is arranged in pairs, and the busbar 2 accommodating cavities in the socket shell are arranged in pairs and arranged in the thickness direction of the busbar 2. Of course, in other embodiments, the busbar 2 accommodating cavities can also be arranged side by side in the width direction of the busbar 2.

[0030] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, the patent protection scope of the utility model is subject to the claims, and any equivalent structural changes made by referring to the contents of the specification and drawings of the utility model should also be included in the protection scope of the utility model.
