The working principle of the socket in the embodiment 1 is as follows: first, during the insertion of the plug 1 into the receptacle 2, the first and second introduction arcs 2311 and 2321 may guide the plug 1 (one first introduction arc 2311 and two second introduction arcs 2321 located at one end of the receptacle insulator 21 constitute a three-sided rounded introduction structure, the first introduction arc 2311 guides the sixth introduction arc 1314, and the second introduction arc 2321 guides the fifth introduction arc 1325), so that the plug 1 can be smoothly inserted into the receptacle 2. The first socket fixing portion 231, the second socket fixing portion 232, the third socket fixing portion 233, the first introduction arc 2311, and the second introduction arc 2321 are provided on the surface of the socket insulator 21, thereby preventing the surface of the socket insulator 21 from directly contacting the plug 1 and preventing the socket insulator 21 from being crushed.

Next, as shown in fig. 13, when the plug 1 is inserted into the socket 2 while being tilted, the engagement portions 23123 of the bump arms 2312 can guide the plug 1 (the third introducing arcs 1311) so that the protrusions 212 can be smoothly accommodated in the second grooves 111; the engaging portion 23123 is also provided on the surface of the bump 212, and can prevent the end of the bump 212 from being crushed.

The working principle of the plug 1 in embodiment 1 is as follows: first, during the insertion of the plug into the receptacle 2, the third and fourth introduction arcs 1311 and 1323 may guide the protrusion 212 (the third introduction arc 1311 guides the engagement portion 23123, and the fourth introduction arc 1323 guides both sides of the end of the protrusion 212) so that the protrusion 212 can be smoothly received in the second groove 111. And the first plug fixing portion 131, the second plug fixing portion 132, the third introduction arc 1311, and the fourth introduction arc 1323 are provided on the surface of the plug insulator 11, thereby preventing the surface of the plug insulator 11 from being in direct contact with the projection 212 and preventing the plug insulator 11 from being crushed.

Next, the fifth introduction arc 1325 and the sixth introduction arc 1314 may guide the plug (the sixth introduction arc 1314 guides the first introduction arc 2311, and the fifth introduction arc 1325 guides the second introduction arc 2321), so that the plug 1 can be smoothly inserted into the socket 2. And the first plug fixing part 131, the second plug fixing part 132, the fifth introduction arc 1325 and the sixth introduction arc 1314 are provided on the surface of the plug insulator 11, thereby preventing the surface of the plug insulator 11 from being in direct contact with the socket 2 and preventing the plug insulator 11 from being crushed.

Since the gap 1324 is provided between the first connecting body 1321 and the solder leg 1322 in the socket 2, the first connecting body 1321 and the solder leg 1322 are independent from each other, and when the solder leg 1322 and the external electronic component are soldered by soldering, the solder ball does not adhere to the first connecting body 1321 (since the size of the plug metal holder 13 itself is small, the solder ball easily adheres to the first connecting body 1321 during soldering, which affects the connection between the solder leg 1322 and the external electronic component).

Example 2:

as shown in fig. 14, the connector according to embodiment 2 of the present invention is modified from that of embodiment 1. Specifically, in the connector of embodiment 2, the second guiding-in arc 2321 is disposed above the contact spring arm 2331, that is, in the process of inserting the plug 1 into the socket 2, the second guiding-in arc 2321 can protect the contact spring arm 2331, so as to prevent the surface of the socket from directly striking the contact spring arm 2331, so that the contact spring arm 2331 is damaged (the contact spring arm 2331 is used as a connecting member for connecting the socket with the plug, the connecting member on the existing socket lacks protection, and in the process of inserting the plug into the plug, the plug directly strikes the connecting member to cause the damage of the connecting member, so that the plug cannot be stably connected with the plug). Meanwhile, the first, second, third, fourth, fifth and sixth introduction arcs 2311, 2321, 1311, 1323, 1325 and 1314 cooperate to allow the plug to be inserted into the receptacle along a correct path, thereby preventing the contact latch 2331 from being damaged when the plug is not inserted into the receptacle along the correct path (e.g., when the plug is inserted into the receptacle near one contact latch 2331, the contact latch 2331 on that side is damaged due to an excessive pressure).

Example 3:

as shown in fig. 15 and 16, the connector according to embodiment 3 of the present invention is modified from that of embodiment 2. Specifically, the socket metal holder 23 and the plug metal holder 13 of the connector in embodiment 3 are different. In the socket metal fitting 23 of embodiment 3, the first introduction arc 2311 and the two second introduction arcs 2321 are integrally formed, and thus the overall strength of the first introduction arc 2311 and the two second introduction arcs 2321 is higher after the arrangement. No snap groove 23124 is provided in extension 23121 of receptacle metal retainer 23. Meanwhile, the third connection body 2322 fitted into the socket insulator 21 is further provided to the second socket fixing portion 232, and the third connection body 2322 is fitted into the socket insulator 21, so that the connection stability between the second socket fixing portion 232 and the socket insulator 21 can be improved.
