Audio socket connector

The present invention relates to a connector, and more particularly to an audio jack connector.

According to the conventional audio jack connector, an insulative housing and a plurality of conductive terminals are included. A circular insertion hole is formed in the middle of the front surface of the insulative housing, and a plurality of terminal slots are arranged on the two sides of the bottom surface of the insulative housing, and the terminal slots are respectively communicated with the insertion holes from the left and right sides. Each of the plurality of conductive terminals has a holding portion, and a contact portion is connected to one edge of each of the holding portions, and a welded portion is connected to the other side of each of the holding portions. The holding portions are respectively fixed in a terminal slot, and the ends of the contact portions are respectively elastically protruded into the insertion holes from the terminal slots, and the soldering portions are all soldered to a circuit board.

However, after the conventional audio socket connector is repeatedly inserted and removed with the docking audio plug, the elastic force of the contact portion is gradually weakened, so that the insertion and extraction force of the audio socket connector is weakened, and the audio plug is easily detached. In addition, when the audio plug is inserted into the audio jack connector, the audio plug is prone to a risk of a momentary break when it is shaken left and right in the plug hole.

Therefore, it is necessary to provide an audio jack connector that is strong in insertion and extraction force and that does not easily weaken the insertion and extraction force. When the docked audio plug is shaken left and right in the plug hole, the risk of a momentary break is not likely to occur.

The purpose of this creation is to provide an audio socket that is not easy to break the risk when the docking audio plug is shaken left and right in the plug hole for the defects and deficiencies of the prior art. Connector.

In order to achieve the above object, the present audio socket connector is soldered to a circuit board for docking with an audio plug, and includes a main body portion, a plurality of conductive terminals and a reinforcing column; and a front surface of the front portion of the main body portion is opened inwardly. a circular insertion hole, a rear side of the bottom surface of the main body portion defines a holding hole, and the fixing hole communicates with the insertion hole; the plurality of conductive terminals are fixed in the main body portion and are respectively disposed on two sides of the insertion hole, and each of the conductive terminals The ends of the reinforcing holes are respectively inserted into the insertion holes from the two sides of the insertion holes; the reinforcing columns are fixed in the fixing holes, and the side walls of the reinforcing columns extend into the insertion holes.

As described above, the creative audio jack connector has a retaining hole formed in a rear portion of the bottom surface of the main body portion, and the retaining hole communicates with the plug hole, and a reinforcing post is fixed in the retaining hole, and the side wall of the reinforcing post is inserted into the plug. In the hole, the rear portion of the insertion hole is slightly narrowed, so that the audio plug can be restrained from swinging left and right in the insertion hole and providing an insertion force, and the insertion force is not easily weakened, so that the risk of a short break is less likely to occur.
