Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1 to Figure 3, the utility model provides a technical solution:

A protection device for a charging interface, comprising a mobile phone 1 and a charging plug 2. The mobile phone 1 is provided with a charging socket 11, and the charging plug 2 is provided with a charging insert 21. When the mobile phone 1 is charging, the charging insert 21 is plugged into the charging port. In the socket 11, the mobile phone 1 on both sides of the charging socket 11 is symmetrically fixed with a fixed frame 12, and the charging plug 2 is provided with an auxiliary fixing protection mechanism for the charging interface, and the auxiliary fixing protection mechanism for the charging interface includes a guide plate 22 and a U-shaped connection. There are two guide plates 23 and auxiliary fixing plate 3, which are symmetrically fixed on both sides of the charging plug 2. The distance between the end faces of the guide plate 22 away from the end of the charging plug 2 is smaller than that between the two fixing frames 12. The distance between them, the surface of guide plate 22 is smooth without burrs in addition.

Both sides of the charging plug 2 are symmetrically fixed with a U-shaped connecting piece 23, the U-shaped connecting piece 23 is at the end far away from the charging insert 21, the guide plate 22 is located between the charging insert 21 and the U-shaped connecting piece 23, and the U-shaped connecting piece 23 is located at the end far away from the charging insert 21. The type connecting piece 23 has certain elasticity.

The U-shaped connecting piece 23 is fixedly provided with an auxiliary fixing plate 3, and the auxiliary fixing plate 3 is provided with a guide fitting hole 31, and the guide fitting hole 31 is inserted with a guide insertion plate 22, and the inner surface of the guide fitting hole 31 is smooth and free of burrs. And the inner wall of the guide fitting hole 31 is in contact with the side wall of the guide plate 22 .

One end of the auxiliary fixing plate 3 away from the U-shaped connecting piece 23 is integrally formed with an auxiliary fixing block 32. When the mobile phone 1 is charging, the auxiliary fixing block 32 is plugged into the fixing frame 12. In addition, the number of auxiliary fixing blocks 32 can be determined according to The actual use requirements are set, and the length of the auxiliary fixing block 32 is equal to the distance from the inner end surface of the fixing frame 12 away from the mobile phone 1 to the mobile phone 1, and when the auxiliary fixing block 32 is plugged into the fixing frame 12, it is far away from the end of the mobile phone 1 The end surface of the fixed frame 12 is in contact with the end surface away from the end of the mobile phone 1 .
