A gap is formed between the locking part 13 and the inserting part 11, the locking groove 131 is not communicated with the guiding groove 111, even if the butt connector 200 cannot completely seal the gap when being buckled with the locking groove 131, because the locking groove 131 is not communicated with the guiding groove 111, water vapor is not easy to directly enter the guiding groove 111 through the gap and further enter the electric connection slot 121.

The socket body 1 further comprises a connecting portion 14 located between the base portion 12 and the inserting portion 11, the locking portion 13 protrudes forward from the connecting portion 14, and the base portion 12, the inserting portion 11, the connecting portion 14 and the locking portion 13 are all integrally formed.

In addition, since the electrical connector 100 is first installed on the electronic device, and the panel 300 is installed on the electronic device along the front-back direction, in order to facilitate the installation of the panel 300 and the connection portion 14, the installation process should be free of other obstacles, so as to prevent the locking portions 13 and the insertion portions 11 from having protruding portions to block the engagement between the panel 300 and the connection portion 14. Therefore, the projected outlines of the locking portions 13 and the mating portions 11 are located within the projected outline of the connecting portion 14, as viewed in the front-rear direction.

The waterproof part 6 is sleeved on the outer side surface of the connecting part 14, in order to enable the waterproof part 6 to be installed more stably, a first groove 141 is formed in the outer side surface of the connecting part 14, and the waterproof part 6 is embedded in the first groove 141.

In order to enhance the waterproof effect when the electrical connector 100 is mated with the mating connector 200, a sealing member 7 is sleeved outside the mating part 11, and the sealing member 7 is partially located in a gap between the locking part 13 and the mating part 11. By the arrangement of the sealing member 7, moisture is not easily introduced into the guiding groove 111 and further into the electrical connection slot 121 by being blocked by the sealing member 7, and thus, the signal of the electrical connector 100 is not easily affected and the electrical connector 100 is not easily damaged. In order to make the installation of the sealing member 7 more stable, the sealing member 7 is disposed at one end of the insertion part 11 close to the connecting part 14, and a second groove 142 is disposed on a front end surface of the connecting part 14 for embedding the sealing member 7 therein, and the sealing member 7 is embedded in the second groove 142, but in other embodiments, the second groove 142 may also be disposed on the insertion part 11. Of course, in other embodiments, the sealing member 7 may be provided in plurality, and the more the sealing member 7 is provided, the better the waterproof effect is. When the sealing member 7 is provided with a plurality of grooves, the second grooves 142 can be correspondingly provided, so that the sealing member 7 is embedded therein, the stability of the sealing member 7 is facilitated, and the waterproof effect is improved.
