[0029] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Combined with Figure 1 and attached Figure 2 As shown, a wiring harness male and female socket assembly includes a male connector 10 and a female socket 20 that matches the male connector 10.

[0031] Combined with Figure 2 , Attachment Figure 4 To Attachment Figure 8As shown, the male connector 10 includes a connector housing 11, a first terminal group, and a first connector 12. The first connector 12 is fixedly installed on the connector housing 11. The first connector 12 is provided with a connecting mouth 121. The connecting mouth 121 is provided with a tooth portion 122. The tooth portions 122 are specifically provided at three locations and are equidistantly distributed in a circle.

[0032] Combined with Figure 5 , Attachment Figure 6 and attached Figure 8 As shown, the first terminal group is arranged between the connector housing 11 and the first connector 12, and the first terminal group includes a first terminal frame 13, and a plurality of male terminals 14 fixedly arranged at the first terminal frame 13, and a circular electrical connection cavity 131 is opened at the first terminal frame 13, and the first contact end 141 of the male terminal 14 is conical and exposed on the inner wall of the electrical connection cavity 131;

[0033] Combined with Figure 1 and attached Figure 3 As shown, the female connector 20 includes a second connector 21 and a second terminal group. The second connector 21 is provided with a connection opening 211 for connecting with the connection mouth 121 of the male connector 10. The second terminal group is fixedly mounted on the connection opening 211 of the second connector 21. The connection opening 211 is provided with a tooth groove 212 for matching with the tooth portion 122 of the connection mouth 121. The number of the tooth grooves 212 corresponds to the number of the tooth portions 122. The tooth grooves 212 are also specifically three and are equidistantly distributed in a circumferential manner. The lower side of the tooth groove 212 is provided with an inner wall annular groove 213.

[0034] Combined with Figure 1 To Attachment Figure 3 As shown, the second terminal group includes a second terminal frame 22, and a plurality of female terminals 23 fixedly arranged at the second terminal frame 22, and the second contact end 231 of the female terminal 23 is fixedly arranged at the cylindrical outer wall of the second terminal frame 22. When the male connector 10 is connected to the female socket 20, the male connector 10 is rotated, and the first contact end 141 of the male terminal 14 contacts and is electrically connected with the second contact end 231 of the female terminal 23.

[0035] As attached Figure 3 As shown, a limit spring fastener 24 is fixedly arranged around the second connecting member 21 of the female socket 20, and a radial opening 214 is opened in the inner wall annular groove 213, and a spring head 241 of the limit spring fastener 24 is movably arranged in the radial opening 214. Figure 1As shown, the spring head 241 of the position-limiting spring fastener 24 is elastically arranged in the inner wall annular groove 213. When the male connector 10 is connected to the female connector 20, the male connector 10 is rotated, and the spring head 241 of the position-limiting spring fastener 24 is driven to rebound when the male connector 10 rotates, and a rebound sound is emitted, generating a rotating hand feeling. After the spring head 241 of the position-limiting spring fastener 24 rebounds, it will limit the male connector 10, preventing the male connector 10 from spontaneously rotating during use and causing it to fall off from the female connector 20.

[0036] The inner cavity of the connector housing 11 of the male connector 10 is fixedly provided with a built-in connector 16, and the first connector 12 is buckled with the built-in connector 16. The first connector 12 is provided with a positioning protrusion 123 between the two latching teeth 122, and the second connector 21 is provided with a positioning straight groove 215 that matches the positioning protrusion 123. When the male connector 10 is connected to the female connector 20, the positioning protrusion 123 of the first connector 12 matches the positioning straight groove 215 of the second connector 21 to play a positioning role, ensuring that the connection mouth 121 of the male connector 10 is correctly inserted into the connection mouth 211 of the female connector 20.

[0037] The first terminal group also includes a first terminal plate 15, a first contact end 141 is provided at the lower side of the male terminal 14, a first pin 142 is provided at the upper side of the male terminal 14, the first pin 142 is inserted into the first terminal plate 15, and the first terminal plate 15 is snap-connected with the first terminal frame 13. Figure 8 As shown, the first pin 142 is exposed from the first terminal plate 15, which is convenient for connecting with the wire 17. The female socket 20 includes a second terminal plate 25, a second contact end 231 is arranged on the upper side of the female terminal 23, and a second pin 232 is arranged on the lower side of the female terminal 23, and the second pin 232 is inserted into the second terminal plate 25.

[0038] When the male connector 10 and the female connector 20 are blindly connected, the male connector 10 is rotated relative to the female connector 20. Figure 1 and attached Figure 2 As shown, when the positioning protrusion 123 of the male connector 10 and the positioning straight groove 215 of the female seat 20 are aligned with each other, the tooth portion 122 of the male connector 10 is smoothly inserted into the tooth groove 212 of the female seat 20, and the connecting mouth 121 of the male connector 10 can be smoothly inserted into the connecting mouth 211 of the female seat 20; then the male connector 10 is rotated again, and the tooth portion 122 of the male connector 10 performs a circular motion at the annular groove 213 on the inner wall of the female seat 20. During the rotation, the male connector 10 drives the spring head 241 of the limiting spring fastener 24 to rebound, making a rebound sound, generating a rotating feel, and serving as a prompt that the male connector and the female seat have been connected. At this time, the first contact end 141 of the male connector 10 is in contact with the second contact end 231 of the female seat 20, thereby realizing the electrical connection between the male connector 10 and the female seat 20.

[0039] The present invention adopts a rotational connection method between the male connector 10 and the female connector 20. Compared with the existing snap-on connection method, the present invention has better connection tightness, and the male connector 10 is not easy to fall off from the female connector 20; moreover, the male connector 10 and the female connector 20 can be blindly connected. When the positioning protrusion 123 of the male connector 10 is just aligned with the positioning straight groove 215 of the female connector 20, the tooth portion 122 of the male connector 10 is directly and smoothly inserted into the tooth groove 212 of the female connector 20, and the operation is simple and convenient.
