Description

Technical Field

[0001] The invention relates to terminal field technology, in particular to a plug-in structure with high current, high clamping force and fast power extraction. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. Terminals are an important medium for plugging connectors.

[0003] Existing connectors need to transmit large currents in certain products. During the transmission of large currents, the stability of the connection process between the male end and the female end needs to be ensured. In order to ensure the clamping force, the existing terminals choose to fit and fix elastic clamping plates on the surface of the female end. When clamping the male end, this structure provides a holding force to the entire outer surface of the female terminal, which cannot guarantee the holding force of the contact part between the female end and the male end, and cannot guarantee the stability of the connection process between the male end and the female end. At the same time, this structure requires the clamping plate and the female end to be fixedly connected together, making the overall assembly method more complicated. Therefore, it is necessary to make further improvements to the existing terminal structure. Summary of the invention

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-current, high-clamping-force, fast-power-taking plug-in structure comprises a female end, a male end and a rigid clip; the female end comprises an integrally formed first main body and two first elastic parts extending forward from the front end of the first main body, the two first elastic parts are arranged up and down, and the front ends of the two first elastic parts are respectively bent inwardly to form contact parts, and the two contact parts are close to each other under the action of the two first elastic parts; the male end comprises a plug connector that cooperates with the two contact parts; the rigid clip is detachably arranged on the female end, the rigid clip comprises an integrally formed second main body and two second elastic parts extending forward from the front end of the second main body, the two second elastic parts are arranged up and down and are located on the outside of the corresponding first elastic part, the front end of each second elastic part has a clamping part, the clamping part on each second elastic part corresponds to the position of the corresponding contact part and is clamped on the outside of the corresponding contact part, and the clamping part causes the two contact parts to be clamped under the action of the second elastic part.

[0007] As a preferred solution, the front end of the contact portion is integrally bent outward to form a guide portion, and the upper and lower surfaces of the outer end of the plug connector are provided with guide surfaces that cooperate with the guide portion.

[0008] As a preferred solution, the second main body parts are two extending up and down, and the two second main body parts are respectively located on the left and right sides of the first main body part, and the two second elastic parts are also two groups symmetrically arranged on the left and right sides. The second elastic parts of each group are respectively extended forward as a whole from the upper and lower ends of the corresponding two second main body parts, and the two second main body parts are clamped and fixed on the left and right sides of the first main body part under the action of the second elastic parts.

[0009] As a preferred solution, the first elastic portion includes four elastic members arranged in a transverse manner and spaced apart from each other, and the contact portion is provided on each elastic member.

[0010] As a preferred solution, a limiting groove is recessed on the outer side of the contact portion, and the clamping portion cooperates with the limiting groove.

[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0014] The rigid clip is detachably arranged on the female end, so that it does not need to be fixed together with the female terminal, and the assembly process is more convenient; and the front end of each second elastic part is provided with a clamping part, and the clamping part on each second elastic part corresponds to the position of the corresponding contact part and is tightened on the outside of the corresponding contact part.

[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 rigid clip 30.

[0031] The female end 10 includes an integrally formed first main body 11 and two first elastic parts 12 extending forward from the front end of the first main body 11. The two first elastic parts 12 are arranged up and down, and the front ends of the two first elastic parts 12 are respectively bent inwardly to form a contact part 13. The two contact parts 13 are close to each other under the action of the two first elastic parts 12. In this embodiment, the front end of the contact part 13 is integrally bent outward to form a guide part 131. The first elastic part 12 includes four elastic members 121 arranged in a transverse interval, and each elastic member 121 is provided with the contact part 13. The arrangement of the four elastic members 121 ensures that the contact parts 13 on the four elastic members 121 are in continuous contact with the male end 20 during the plug-in process, even if a certain angle of twisting or a certain degree of vibration occurs, the stability of the plug-in process is further ensured. A limiting groove 101 is recessed on the outer side of the contact part 13. The female end 10 is arranged in a plurality of transverse intervals, and the plurality of female ends 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 by an external fixing member.

[0032] The male end 20 includes a plug connector 21 that cooperates with the two contact portions 13; in this embodiment, the upper and lower surfaces of the outer end of the plug connector 21 are provided with guide surfaces 211 that cooperate with the guide portion 131; through the cooperation between the guide surface 211 and the guide portion 131, the plugging process of the male end 20 and the female end 10 is facilitated when the clamping force is increased. The male end 20 is provided with a plurality of plug connectors 21 arranged in a transverse interval, and each plug connector 21 is plugged and connected with the corresponding female end 10.

[0033] The steel clip 30 is detachably arranged on the female end 10. The steel clip 30 includes an integrally formed second main body 31 and two second elastic parts 32 integrally extending forward from the front end of the second main body 31. The two second elastic parts 32 are arranged up and down and are located on the outer side of the corresponding first elastic part 12. The front end of each second elastic part 32 has a clamping part 33. The clamping part 33 on each second elastic part 32 corresponds to the position of the corresponding contact part 13 and is clamped on the outer side of the corresponding contact part 13. The clamping part 33 causes the two contact parts 13 to be clamped under the action of the second elastic part 32; the clamping force provided by the clamping part 33 directly acts on the contact part 13, thereby ensuring that the contact part 13 provides sufficient holding force for the plug connector 21 of the male end 20, and preventing the male end 20 from falling off from the female end 10. At the same time, the steel clip 30 can also be clamped and fixed on the female end 10 by the clamping force provided by the second elastic part 32, without the need for an additional fixing structure, making the assembly process more convenient.

[0034] In this embodiment, the second main body 31 is two extending up and down, and the two second main body 31 is respectively located on the left and right sides of the first main body 11, and the two second elastic parts 32 are also two groups symmetrically arranged, and each group of second elastic parts 32 is respectively extended forward from the upper and lower ends of the corresponding two second main body 31, and the two second main body 31 is clamped and fixed on the left and right sides of the first main body 11 under the action of the second elastic parts 32; so that it can be clamped and fixed on the female end 10 by its own elastic force, without the need for an additional fixing structure, and the overall structure is simpler. The clamping part 33 cooperates with the limiting groove 101, and the position of the clamping part 33 is positioned by the limiting groove 101 to ensure that the force of the clamping part 33 acts completely on the contact part 13.

[0035] The design focus of the present invention is: the rigid clip is detachably arranged on the female end, so that it does not need to be fixed together with the female terminal, and the assembly process is more convenient; and the front end of each second elastic part is provided with a clamping part, and the clamping part on each second elastic part corresponds to the position of the corresponding contact part and is tightened on the outside of the corresponding contact part. Under the action of the second elastic part, the clamping part causes the two contact parts to be clamped, so that the clamping part is directly clamped on the outside of the contact part, so that the entire clamping force acts on the contact part, ensuring sufficient clamping force. During the process of large current transmission, the stability of the connection process between the male end and the female end can also be guaranteed.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight 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.
