Further, the curb plate is the C type, and is equipped with one on the curb plate and tears the opening, it further buckles and extends to tear the opening on the bottom plate, just it is equipped with the welding foot that downwardly extending to tear in the mouth.

Further, the convex ring part protrudes forwards from the front end face of the annular base part, and the convex ring part is also annular but smaller than the annular base part in size.

Further, the collar portion is formed on an inner ring edge of the annular base portion.

Further, the mounting portion extends horizontally rearward from a top edge of the annular base portion and is integrally formed with the annular base portion.

Further, the installation portion only covers a part of the opening, and the installation portion is fixedly connected with the top plate.

Furthermore, a splicing seam is arranged on the bottom plate.

Compared with the prior art, the utility model discloses USB electric connector passes through the setting of beaded finish, makes its peripheral complete parcel of formation cover all around at metal casing's butt joint frame mouth, has increased metal casing's intensity, has improved USB electric connector's reliability and security, and the beaded finish also can be filled or reduced the butt joint frame mouth all around and the gap between the computer casing in addition, can avoid inside the entering computer of dust foreign matter etc. makes the product whole more pleasing to the eye.

Detailed Description

Referring to fig. 1 to 2, the present invention provides a USB electrical connector, which includes: the connector comprises an insulating body 10, a conductive terminal 20 accommodated in the insulating body 10, a metal shell 30 coated on the surface of the insulating body 10, and a reinforcing ring 40 mounted on the metal shell 30.

The insulating body 10 has a mating tongue 11 protruding forward to connect with a mating end electrical connector, and a plurality of conductive terminals 20 are distributed on the upper and lower surfaces of the mating tongue 11.

The metal shell 30 is provided with a top plate 31, a bottom plate 32 and a pair of side plates 33, the top plate 31, the bottom plate 32 and the side plates 33 together enclose a plug cavity 34 and a pair of frame interfaces 341, and the plug cavity 34 is used for accommodating the mating tongue plate 11 and is used for inserting a mating end electrical connector. The metal shell 30 is formed by integral punching, the top plate 31 is provided with an opening 35, the opening 35 penetrates through the plug cavity 34 downwards, and a spring plate protruding downwards is arranged in the opening 35 and used for abutting against the butt joint end electric connector to increase the plug force. A splicing seam 36 is arranged on the bottom plate 32, and the splicing seam 36 is positioned right below the butt tongue plate 11. In the preferred embodiment of the present invention, the USB electrical connector is a Type C USB electrical connector, the side plate 33 is C-shaped, and a tearing opening 37 is opened on the side plate 33, the tearing opening 37 is further bent and extended to the bottom plate 32, and a welding foot 38 extending downward is provided in the tearing opening 37 for welding to a circuit board.

The reinforcing ring 40 is preferably an annular metal member, which surrounds the docking frame opening 341 and is welded and fixed to the top plate 31 of the metal shell 30 by spot welding, the reinforcing ring 40 reinforces the strength of the docking frame opening 341, and at the same time, due to the existence of the reinforcing ring 40, after the power connector is mounted on the notebook computer, the gap between the power connector and the computer case is filled or reduced by the reinforcing ring 40, thereby effectively preventing foreign matters from entering the inside of the case.
