Example 2:

the connector in embodiment 2 of the present invention is improved on the basis of embodiment 1. Specifically, in the connector of embodiment 2, the fourth guiding arc 22121 is disposed above the contact elastic arm 22132, that is, in the process of inserting the plug into the socket, the fourth guiding arc 22121 can protect the contact elastic arm 22132, so as to prevent the surface of the plug from directly striking the contact elastic arm 22132 to damage the contact elastic arm 22132 (the contact elastic arm 22132 is used as a connector of the socket to connect the plug, the connector on the existing socket lacks protection, and in the process of inserting the plug into the plug, the plug directly strikes the connector to damage the connector, which results in the unstable connection between the plug and the plug). Meanwhile, in the process of connecting the socket and the plug, the first lead-in arc 1213 contacts with the third lead-in arc 221112211, and the second lead-in arc 1214 contacts with the fourth lead-in arc 22121, so as to guide the socket and the plug together, so that the plug can be inserted into the socket according to a correct path, and damage to the contact elastic arm 22132 caused when the plug is not inserted into the socket according to the correct path is avoided (for example, when the plug is inserted into the socket near one side of the contact elastic arm 22132, the contact elastic arm 22132 on the side is damaged due to excessive pressure).

Embodiment 2 the rest of the structure and the operation principle are the same as those of embodiment 1.

Example 4:

as shown in fig. 22 and 23, the connector according to embodiment 4 of the present invention is modified from that of embodiment 3. The socket of embodiment 4 further includes two connecting arms 222, the two connecting arms 222 are respectively disposed on both sides of the socket insulator, and the end portions of the connecting arms 222 are connected to the second socket fixing portions 2212 in the socket fixing member 221. As shown in fig. 22, the two socket fixing members 221 and the two connecting arms 222 together form a shielding cover 22, and the adjacent socket fixing members 221 and the connecting arms 222 are connected to each other, the shielding cover 22 is integrally formed, and the shielding cover 22 is sleeved on the socket insulator 21. The shield 22 is a metal frame strip, and when the shield 22 is grounded, the shield 22 can shield the external signal interference received by the receptacle signal terminal.

Example 4 the rest of the structure and the operation principle are the same as those of example 3.

Example 5:

as shown in fig. 24 and 25, the connector according to embodiment 5 of the present invention is modified from that of embodiment 4. Specifically, the first socket fixing portion 2211 of the connector according to embodiment 5 is further provided with an anti-collision arm 2214, one end of the anti-collision arm 2214 is fastened to an end portion of the boss 216, the anti-collision arm 2214 is made of a metal material, and the end portion of the boss 216 can be protected by fastening the anti-collision arm 2214 to the end portion of the boss 216.

Example 5 the rest of the structure and the operation principle are the same as those of example 4.

Example 6:

the embodiment 6 of the utility model discloses an electronic equipment, this electronic equipment include embodiment 1 to embodiment 5 arbitrary connector.

Utility model embodiment 6 after electronic equipment adopted above-mentioned structure, when the plug among the electronic equipment welded with electronic component, welding arm 1221 was equipped with storage solder groove 1224 with circular arc welding section 1223's junction, and the solder ball that the welding formed can be saved in storage solder groove 1224 to avoid the solder ball to the influence of plug leg size, guarantee plug and socket can normally be connected.

The connector and the electronic device provided by the present invention are described in detail above, and the principle and the implementation of the present invention are explained by applying specific examples, and the description of the above examples is only used to help understanding the method and the core idea of the present invention; meanwhile, to the general technical personnel in this field, according to the utility model discloses an idea, all can have the change part on concrete implementation and application scope, to sum up, this description content only is the utility model discloses an embodiment, does not consequently restrict the utility model discloses a patent scope, all utilize the equivalent structure or the equivalent flow transform that the content of the description and the attached drawing did, or directly or indirectly use in other relevant technical fields, all the same reason is included in the utility model discloses a patent protection scope. And should not be construed as limiting the invention.
