Problems solved by technology

[0002] Existing USB plugs such as figure 1 As shown, there is no dust cover at the USB interface, and its DIP pin is S-shaped, so it can only be assembled by hand, and SMT operation cannot be performed. The terminal and the base of the existing USB plug are assembled by press-fit interference fit of a jig. , which is not conducive to the improvement of production efficiency and the extension of service life. The existing USB plugs are all simple frame shapes without any special design, which is easy to damage the PCB board during use.

Embodiment Construction

[0011] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] like figure 2 As shown, a USB plug has a shell 1, the front end of the shell 1 has a USB interface, and the shell 1 is located at the USB interface and is equipped with a dust cover for covering the front opening of the USB interface. figure 2 The middle dust cover is not shown, the rear end of shell 1 has DIP pin 2, DIP pin 2 is in-line, the base is installed in the shell 1, and the terminal is installed on the base, the terminal and the base adopt internal Assembled in a molded manner.

[0013] The USB interface is in the shape of a covered frame. There is a certain distance between the rear edge of the USB interface and the front edge of DIP pin 2. The rear edge of the USB interface has a convex plate extending backward. Bent barb plate 3, the extension direction of the barb plate 3 is the same as the extension direction of the D...

Abstract

The invention discloses a USB (Universal Serial Bus) plug. The USB plug comprises a shell, wherein the front end part of the shell is provided with a USB interface; the shell is provided with a dust cover used for covering an opening positioned on the front end surface of the USB interface in the position of the USB interface; the rear end part of the shell is provided with a DIP (Dual In-line Package) pin; the DIP pin is in an in-line type; the shell is internally provided with a base; a terminal is arranged on the base; the terminal and the base are assembled by adopting an internal forming mode; the rear end edge of the USB interface is provided with a backwards extending convex plate; the convex plate is connected with a reversed hook plate with a back bent; and the extending direction of the reversed hook plate is the same as the extending direction of the DIP pin. The USB plug disclosed by the invention has the advantages of no interference in assembling processes, SMT (Surface Mount Technology) type convenient welding mode, dust prevention, convenience for assembly and production and effective prevention of PCB (Printed Circuit Board) scratch in producing and using processes.

Description

technical field [0001] The invention relates to a USB plug. Background technique [0002] Existing USB plugs such as figure 1 As shown, there is no dust cover at the USB interface, and its DIP pin is S-shaped, so it can only be assembled by hand, and SMT operation cannot be performed. The terminal and the base of the existing USB plug are assembled by press-fit interference fit of a jig. , It is not conducive to the improvement of production efficiency and the extension of service life. The existing USB plugs are all simple frame shapes without any special design, which is easy to damage the PCB board during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a USB plug, which is convenient for assembly and production. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a USB plug with a shell, the front end of the shell has a USB inter...
