Anti-interference USB plug

Abstract

The invention relates to an anti-interference USB plug. The plug comprises a rubber core assembly, a plugging shell and a wire wrapping shell, the plugging shell is integrally formed, and the wire wrapping shell is formed by detachably connecting a first wire hooping piece and a second wire hooping piece; and the front ends of the first wire hooping piece and the second wire hooping piece form a connecting port, the rear end of the plug-in shell is provided with a connecting part adaptively coated by the connecting port, and the rear end of the connecting part is provided with a first limiting protrusion. A second limiting protrusion matched with the first limiting protrusion is arranged at the front end of the wire wrapping shell, a second accommodating cavity for accommodating the first limiting protrusion is formed in the inner side of the second limiting protrusion, and the front end and the rear end of the second limiting protrusion are of opening structures; through cooperation of the first limiting protrusion and the second limiting protrusion, the positioning effect is achieved, the first wire hooping piece and the second wire hooping piece are assembled more accurately, the fixing structure of the wire wrapping shell and rubber wrapping can be enhanced during rubber wrapping, degumming is prevented, in addition, machining and production of automatic equipment are facilitated, and the production efficiency is high.

Description

【Technical field】 [0001] The invention relates to the technical field, in particular to an anti-jamming USB plug. 【Background technique】 [0002] The USB plug in the prior art mainly includes an upper shell, a lower shell, and a rubber core assembly. During production, it is necessary to first assemble the wire with the upper shell and the lower shell, and then weld the core wire of the wire to the rubber core assembly, and finally the glue The core assembly is pushed into the shell and encapsulated; this structure has the following problems: [0003] 1. It is not only difficult to disassemble during repair and disassembly, but also easy to damage the rubber core components, and the scrap rate is high; [0004] 2. The upper shell and the lower shell are only connected by a buckle structure, and there are gaps, which may easily cause electromagnetic wave leakage and external interference to video signals; [0005] 3. There is no fixed structure between the upper shell and t...

Problems solved by technology

[0003] 1. It is not only difficult to disassemble during repair and disassembly, but also easy to damage the rubber core components, and the scrap rate is high;

[0004] 2. The upper shell and the lower shell are only connected by a buckle structure, and there are gaps, which may easily cause electromagnetic wave leakage and external interference to video signals;

[0005] 3. There is no fixed structure between the upper shell and the lower shell and the lagging, which is prone to serious degumming
