Voice socket

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of voice socket that is used for phonetic entry/output especially.

[background technology]

The United States Patent (USP) the 6th that on November 12nd, 2002 was announced, 478, disclosed a kind of existing voice socket for No. 629, this voice socket comprises insulating body and terminal group, insulating body one end is provided with the docking section, the docking section is provided with a spliced eye along axis direction, and insulating body inside also is provided with the plug receiving space that is communicated with spliced eye, and terminal group comprises some flexible terminals that are contained in insulating body.During use, banjo inserts receiving space along spliced eye, and flexible terminal is squeezed and each section of elastic deformation and banjo takes place closely contacts, and simultaneously plug is immobilizated in the insulating body.Yet because the elastic force size that insulating body two-side elastic terminal elastic arm is produced is unequal, lateral shift takes place in banjo easily in receiving space, the plastic cement inwall generation of banjo tail end and receiving space rubs slotting, after repeatedly pegging graft, the plastic cement inwall can be worn, and the plug skew is even more serious, and it is loosening to cause plug to take place in receiving space, with the forward contact force deficiency of flexible terminal, thereby the machinery and the electric property of voice socket have been influenced.

[utility model content]

The purpose of this utility model is to provide a kind of to be had big contact engaging and separating force and can prevent the voice socket that the plastic liner seat decreases.

For achieving the above object, the utility model voice socket comprises insulating body, is contained in the terminal group and the retaining piece of insulating body, insulating body one end is provided with the docking section, the docking section is provided with a spliced eye along axis direction, insulating body inside is provided with the plug receiving space that is communicated with spliced eye, and the insulating body end is provided with the plug receiving space and is connected in order to accommodate the retaining piece slot.

Compared to prior art, the utility model voice socket is provided with retaining piece, when the banjo connector inserts the plug receiving space by spliced eye, the corresponding contact site interference of retaining piece and pin connector tail end, prevent the plastic cement inner wall abrasion of plug receiving space, increase contact engaging and separating force, make it be immobilizated in insulating body, closely contact with the terminal in being contained in insulating body, thus the machinery and the electrical characteristic of raising voice socket.
