Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and drawings.

Please refer to FIG. 1 , the speaker connector 1 of the present invention includes an insulating body 10 and two conductive terminals 20 .

Please refer to FIG. 1 , FIG. 2 and FIG. 4 , the insulating housing 10 has a substantially cylindrical base 11 . Two ribs 12 in the shape of square columns extend downward from the bottom of the base 11 . The top surface of the base 11 is an inclined surface, and four symmetrically arranged protrusions 13 extend upward from the top surface. A groove 111 is defined downwards in the middle of the top surface of the base 11 . Both sides of the bottom wall of the groove 111 are downwardly provided with terminal grooves 112 penetrating through the base 11 and the rib 12 . Between the two terminal grooves 112 , a boss 113 extends upwards from the bottom wall of the groove 111 , and the top surface of the boss 113 defines two locking grooves 114 downwards. A resisting arm 121 protrudes from a lower end of the protruding rib 12 toward the terminal slot 112 .

Please refer to FIG. 2 again, the conductive terminal 20 includes a holding portion 21 in the shape of a vertical plate. The upper end of the holding portion 21 is bent and extended to one side, and then bent and extended in the opposite direction to form a “U”-shaped elastic compression portion 22 . A front end of the elastic compression portion 22 is bent downwards to extend a buckle 23 , and a side edge of the elastic compression portion 22 is bent outwards to extend a first contact portion 24 . The end of the first contact portion 24 is bent upward and then downward to form the first contact head 241 .

A resilient portion 25 extends from a lower end of the holding portion 21 along a back and forth bend. A second contact portion 26 in the shape of a strip extends downward from the lower end of the end of the elastic portion 25 . The end of the second contact portion 26 forms an arc-shaped second contact head 261 .
