Description

Improved structure of multi-port audio socket

Technical field

The utility model provides an improved structure of a multi-port audio socket, in particular relates to an improved structure of an audio socket capable of providing good interference protection effect.

Background technique

Since the transmission of electrical connector signals is affected by external or internal signals, there will be signal interference. Therefore, current electrical connectors are generally equipped with grounding devices for reducing signal interference, such as in the insulating shell of electrical connectors. The body is covered with a metal shell, or the grounding terminal of the electrical connector is plugged with the mating electrical connector to form a ground loop. They can all be used to reduce noise interference, and the metal shell adopts a separate structure. It is conducive to the stable size and convenient assembly of the pressure during manufacturing. As shown in FIG. There are cylindrical protrusions 11, storage chambers 12, buckle grooves 13, slots 14 and fixing pieces 15, and several conductive terminals 2, 21 are installed in the storage chamber 12 of the insulating shell 1, when a plug of a male socket is inserted into When plugging in, it can be used to contact and conduct with the plug to transmit signals. Several sleeve covers 4 are inserted into the cylindrical protrusion 11 of the above-mentioned insulating housing 1 to prevent the user from inserting it by mistake when inserting the male seat (not marked); A grounding piece 3, which is provided with a sleeve hole 31, a slot 32 and a grounding piece 33, the sleeve hole 31 of the grounding piece 3 is inserted into the cylindrical protrusion 11 of the insulating shell 1, and the grounding piece 33 passes through the insulating shell 1 The slot 14 is inserted into the circuit board (not marked) to guide signal transmission; several cylindrical shells 5 have two pins 51, and the two pins 51 pass through the jack 32 of the grounding piece 3 and are inserted into the buckle of the insulating shell 1. The groove 13 is connected to the insulating shell 1 and the grounding piece 3, and when a male socket is inserted, the signal transmission of the grounding piece 33 is facilitated. The disadvantages are: because the grounding element 3 and the cylindrical shell 5 are of a separate structure, there is a gap when they are inserted, so that the contact between the two cannot be firmly sealed, so there will be poor contact, which will affect the grounding effect. Therefore above shortcoming needs to be improved.

Contents of the invention
