Abstract:
1. An audio jack connector adapted for soldering on a circuit board and engaging with an audio plug connector, comprising: an insulating housing having a main body, and an insertion portion connecting with one side of the main body, the insertion portion defining an insertion hole extending along a front-to-rear direction to penetrate through a front face and a rear face of the insertion portion for receiving the audio plug connector therein, the main body defining a plurality of terminal grooves with bottoms thereof passing through a bottom surface of the main body, the insulating housing defining a plurality of mouths communicating between the insertion hole and the terminal grooves; and a plurality of terminals disposed in the terminal grooves of the main body of the insulating housing, each terminal having a contact portion forming at one side thereof projecting into the insertion hole of the insulating housing through the mouth to electrically contact with the audio plug connector, and a soldering portion forming at a bottom thereof received in the bottom of the terminal groove to be soldered on the circuit board; wherein the terminal grooves are designated as a plurality of first terminal grooves, a second terminal groove and a third terminal groove, the terminals are designated as a plurality of first terminals disposed to the first terminal grooves respectively, a second terminal disposed to the second terminal groove and a third terminal disposed to the third terminal groove, the mouths are designated as a plurality of first mouths, a second mouth and a third mouth, the first mouths communicate between the insertion hole and the first terminal grooves respectively, the second mouth communicates between the insertion hole and the second terminal groove, and the third mouth communicates between the insertion hole and the third terminal groove, each of the first terminal grooves includes a locating groove vertically penetrating through the main body, two fastening slots concaved oppositely from two bottoms of two opposite inner sidewalls of the locating groove, and a receiving groove recessed inward in the bottom surface of the main body and communicating with the locating groove, the first mouth penetrates through a sidewall of the locating groove adjacent to the insertion hole, each of the first terminals has a first base portion, a bottom of the first base portion bends towards a direction perpendicular to the first base portion to form a first soldering portion received in the receiving groove, a top of the first base portion bends towards the same direction as the bend direction of the first soldering portion, and then is inclined downward and away from the first base portion to form a first elastic portion, an outer face of a free end of the first elastic portion is arched outward to form a first contact portion projecting into the insertion hole through the first mouth, a middle of the first base portion and the first elastic portion are located in the locating groove, and two opposite sides of the first base portion are fastened in the fastening slots.
