DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-6 shown in the schematic diagram.

[0026] A high-current connector includes a male head 10 and a female seat 20. The male head 10 is composed of a male head insulating matrix 11, at least one male head positive terminal 12, at least one male head negative terminal 13, and at least one male head signal terminal 14. The male head insulating matrix 11 is provided with an insertion interface 15. The male head positive terminal 12, the male head negative terminal 13, and the male head signal terminal 14 are respectively arranged in the insertion interface 15. The insertion interface 15 is divided into two groups. The male head positive terminal 12 and the male head negative terminal 13 are one group, and the male head signal terminal 14 is the other group. After the insertion interface 15 of the male head 10 is matched and connected with the insertion part 26 of the female seat 20, a tight sealing structure is formed to prevent moisture from penetrating into the connector interior, having better environmental resistance; the insertion interface 15 is a hard insulator to protect the terminals in the male head 10 from colliding with other objects during use, thus causing the terminals to bend and deform.

[0027] The female seat 20 is composed of a female seat insulating matrix 21, at least one female seat positive terminal 22, at least one female seat negative terminal 23, and at least one female seat signal terminal 24. The female seat insulating matrix 21 is provided with an insertion slot 25 that matches the insertion interface 15. Insertion parts 26 are respectively formed in the insertion slot 25. The insertion part 26 further includes terminal slots 27. The female seat positive terminal 22, the female seat negative terminal 23, and the female seat signal terminal 24 are respectively installed in the terminal slots 27 that match the insertion part 26. The insertion part 26 is divided into two groups. The female seat positive terminal 22 and the female seat negative terminal 23 are one group, and the female seat signal terminal 24 is the other group. When the male head 10 and the female seat 20 are plugged and fixed for use, it is possible to avoid the large-current magnetic field interference of the positive and negative terminals on the signal transmission of the signal terminals, thereby transmitting signals more stably.

[0028] Any one of the male head signal terminal 14 and the female seat signal terminal 24 is an elastic metal part 30. When the male head 10 and the female seat 20 are misaligned and connected, the elastic metal part 30 effectively avoids the bending and deformation of the signal terminals and excessive damage to the insertion part 26.

[0029] As Figure 5As shown, the elastic metal part 30 is a spring pin. When the male head 10 is connected to the female seat 20, the spring pins pop out and are respectively connected to the corresponding signal terminals, which is more stable in use and avoids poor contact.

[0030] As Figures 5-6 shown, the male head signal terminal 14 is a spring pin structure, and the female seat signal terminal 24 is a solid pin 31 structure. The spring pins in the male head 10 can apply pressure to the solid pins 31 in the female seat 20, which can prevent the connection parts of the signal terminals from loosening and disconnecting, thus ensuring higher connection stability.

[0031] As Figures 5-6 shown, the female seat signal terminal 24 is a spring pin structure, and the male head signal terminal 14 is a solid pin 31 structure. The spring pins in the female seat 10 can apply pressure to the solid pins 31 in the male head 10, which can prevent the connection parts of the signal terminals from loosening and disconnecting, thus ensuring higher connection stability. The spring pins and the solid pins 31 can be respectively swapped and arranged in the male head 10 and the female seat 20, and the function remains unchanged after the positions are swapped.

[0032] Furthermore, the number of the male head signal terminals 14 is 6PIN, which has high mechanical strength, thus ensuring the reliability and stability of the connection.

[0033] Furthermore, the number of the female seat signal terminals 24 is 6PIN, which has high mechanical strength, thus ensuring the reliability and stability of the connection.

[0034] Furthermore, the female seat 20 extends along the parallel and symmetrical two sides at one end of the connection port with the male head 10. The extended part also includes mounting holes 28, and the female seat 20 is fixedly installed through the mounting holes 28.

[0035] The working principle of the present utility model: When the male head 10 and the female head 20 are connected and used, by utilizing the characteristic that the spring pins can expand and contract under resistance, it avoids the bending deformation of the signal terminals and the excessive force damage of the insertion part 26. The spring pins apply pressure to the solid pins 31, making the connection between the spring pins and the solid pins 31 tighter, which can prevent the connection parts of the signal terminals from loosening and disconnecting, thus making the connection between the terminals more firm and stable, with a longer service life and higher safety.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
