Problems solved by technology
[0002] At present, audio and video connectors, assembled or welded intermediate pin conductors are either solid or hollow with closed front ends. The material cost of solid pin conductors is too high, while the cost of materials for hollow pin conductors with closed front ends is low, but the cost of electroplating is too high and the quality is not easy to control. At present, the middle needle conductor is solid or hollow with a closed front end. During injection molding, the air in the mold body is not easy to discharge, and the air is wrapped in the needle conductor to form a bulge, resulting in an unstable appearance.

The invention discloses an audio and video plug with a front-end-opened needle conductor, which comprises an inner needle conductor, an outer metal tube and an insulated rubber core; the outer metal tube is sleeved on the outer wall of the insulated rubber core; furthermore, the inner needle conductor is electrically connected with the core wire of a cable; the outer metal tube is electrically connected with the ground wire of the cable; an injection molding cavity is arranged in the inner needle conductor; the front end of the inner needle conductor is a closed end; a discharge hole communicated with the injection molding cavity is formed in the closed end; the rear end of the inner needle conductor is an opened end; the opened end is inserted into the insulated rubber core; an injection molding body used for enabling the inner needle conductor, the outer metal tube and the insulated rubber core to be insulated, and fixing and holding the inner needle conductor, the outer metal tube and the insulated rubber core into an integral body is arranged among the inner needle conductor, the outer metal tube and the insulated rubber core. According to the audio and video plug, the bulge phenomenon of the inner needle conductor is avoided in the injection molding process; the attractive degree and the stability of the appearance of the inner needle conductor are improved; simultaneously, the cost is reduced.
Description
technical field [0001] The invention relates to an audio and video plug with a front hole pin conductor and belongs to the technical field of audio and video connectors. Background technique [0002] At present, audio and video connectors, assembled or welded intermediate pin conductors are either solid or hollow with closed front ends. The material cost of solid pin conductors is too high, while the cost of materials for hollow pin conductors with closed front ends is low, but the cost of electroplating is too high and the quality is not easy to control. At present, the middle needle conductor is solid or hollow with a closed front end. During injection molding, the air in the mold body is not easy to discharge, and the air is wrapped in the needle conductor to form a bulge, resulting in an unstable appearance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide an audio an...
