Description
Technical Field
[0001] The utility model relates to terminal field technology, in particular to a plug-in structure with high current, high clamping force and fast power supply. Background Art
[0002] Connectors, also known as connectors in China, are also called joints and sockets. They generally refer to electrical connectors. These are devices that connect two active components, transmitting current or signals. The male and female terminals, when in contact, can transmit information or current, and are also called connectors. The basic performance of connectors can be categorized into three main categories: mechanical, electrical, and environmental. Another important mechanical performance characteristic is the mechanical life of the connector. Terminals are the essential medium for connecting connectors.
[0003] Existing connectors, used in certain products, need to transmit high currents, requiring a stable connection between the male and female terminals. To maintain clamping force, existing terminals employ an elastic clamping plate attached to the female terminal surface. This structure provides a holding force to the entire outer surface of the female terminal when clamping the male terminal, but it fails to maintain sufficient holding force at the contact point between the female and male terminals, nor does it guarantee a stable connection between the male and female terminals. Furthermore, this structure requires a fixed connection between the clamping plate and the female terminal, complicating overall assembly. Therefore, further improvements to existing terminal structures are necessary. Utility Model Content

[0030] Please refer to Figures 1 to 4As shown, it shows the specific structure of a preferred embodiment of the present invention, which includes a female end 10, a male end 20 and a steel clip 30.
[0031] The female connector 10 includes an integrally formed first main body 11 and two first elastic portions 12 extending forward from the front end of the first main body 11. The two first elastic portions 12 are arranged vertically, and the front ends of the two first elastic portions 12 are each bent inward to form a contact portion 13. The two contact portions 13 are brought closer together under the action of the two first elastic portions 12. In this embodiment, the front ends of the contact portions 13 are bent outward to form a guide portion 131. The first elastic portion 12 includes four elastic members 121 arranged laterally and spaced apart, each of which is provided with a contact portion 13. The arrangement of the four elastic members 121 ensures that the contact portions 13 on the four elastic members 121 maintain contact with the male connector 20 during the plugging process, even if a certain degree of twisting or vibration occurs, further ensuring a stable plugging process. The outer side of the contact portion 13 is recessed with a retaining groove 101. The female connector 10 is provided in multiple laterally spaced apart arrangements, and the multiple female connectors 10 are fixedly mounted on a bracket 14. The bracket 14 is provided with a plurality of first positioning holes 102 arranged at intervals in a transverse direction, and the first main body 11 is provided with second positioning holes 103 corresponding to the first positioning holes 102 , so that the female end 10 and the bracket 14 can be positioned and fixed together through external fixing parts.
[0032] The male end 20 includes a plug connector 21 that mates with the two contact portions 13. In this embodiment, the upper and lower surfaces of the outer ends of the plug connector 21 are provided with guide surfaces 211 that mate with the guide portions 131. The cooperation between the guide surfaces 211 and the guide portions 131 facilitates the plugging process between the male end 20 and the female end 10 while increasing the clamping force. The male end 20 is provided with multiple plug connectors 21 arranged in a transversely spaced arrangement, each plug connector 21 being pluggable and connected to a corresponding female end 10.
[0033] The steel clip 30 is detachably mounted on the female end 10. The steel clip 30 includes an integrally formed second main body 31 and two second elastic portions 32 extending forward from the front end of the second main body 31. The two second elastic portions 32 are arranged vertically and located outside the corresponding first elastic portion 12. Each second elastic portion 32 has a clamping portion 33 at its front end. The clamping portion 33 on each second elastic portion 32 corresponds to the position of the corresponding contact portion 13 and clamps onto the outside of the corresponding contact portion 13. Under the action of the second elastic portion 32, the clamping portion 33 clamps the two contact portions 13 together. The clamping force provided by the clamping portion 33 directly acts on the contact portions 13, thereby ensuring that the contact portions 13 provide sufficient holding force for the plug connector 21 of the male end 20 and preventing the male end 20 from falling off the female end 10. The clamping force provided by the second elastic portion 32 can also be used to clamp the steel clip 30 to the female end 10, eliminating the need for additional fixing structures and making the assembly process more convenient.
[0034] In this embodiment, the second main body portions 31 are two vertically extending portions, one located on the left and right sides of the first main body portion 11. The two second elastic portions 32 are also symmetrically arranged in two groups. The second elastic portions 32 of each group extend forward from the upper and lower ends of the corresponding two second main body portions 31. The two second main body portions 31 are clamped and fixed to the left and right sides of the first main body portion 11 under the action of the second elastic portions 32; so that they can be clamped and fixed to the female end 10 through their own elastic force, without the need for additional fixing structures, and the overall structure is simpler. The clamping portion 33 cooperates with the limiting groove 101, and the limiting groove 101 is used to position the clamping portion 33, ensuring that the force of the clamping portion 33 fully acts on the contact portion 13.
[0035] The design focus of this utility model is that the steel clip is detachably mounted on the female end, eliminating the need for fixing it to the female terminal, making the assembly process more convenient. Furthermore, each second elastic portion has a clamping portion at the front end. The clamping portion on each second elastic portion corresponds to the position of the corresponding contact portion and is tightened on the outside of the corresponding contact portion. Under the action of the second elastic portion, the clamping portion clamps the two contact portions together, directly clamping the clamping portion on the outside of the contact portion, thereby applying the full clamping force to the contact portion, ensuring sufficient clamping force. This also ensures a stable connection between the male and female ends during high current transmission.
[0036] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
