[embodiment]

See also Fig. 1 to Figure 11, the utility model socket connector 1 is to be used for and to dock voice plug 2 and cooperate, and this butt joint voice plug 2 comprises preceding contact site 3, middle contact site 4 and back contact site 5.This socket connector 1 comprises metal shell 10, cap 20, insulating body 30, first group of conducting terminal 40, second group of conducting terminal 50, the 3rd group of conducting terminal 60, and structures such as earth terminal 70 and back plug 80.

Wherein, metal shell 10 comprises front 11, and end face 12, left surface 13 and the right flank 14 that extend 11 top, the left and right sides from the front, and end face 12, left surface 13 and right flank 14 are all perpendicular to front 11.Front 11 is provided with three holes 15, and left and right sides face 13,14 lower ends extension downwards respectively are provided with pin 16, to insert circuit board (not drawing among the figure), in addition, metal shell 10 outer surfaces are provided with some concave points 17, to reduce or to eliminate its surface stress, and after making plating, has outward appearance preferably.

Insulating body 30 front surfaces form three inside recessed square potholes 31 side by side, and each pothole 31 substantial middle position extends internally and forms a circular spliced eye 32, insert for butt joint voice plug 2, circular spliced eye 32 upsides are connected with a square aperture 33, and each pothole 31 roughly corner location is provided with insertion mouth 34.

Cap 20, comprise a square plate body 21 and the protuberance 22 that extends forward from square plate body 21, protuberance 22 roughly is hollow cylindrical, its hollow part forms a circular spliced eye 23, run through square plate body 21, square plate body 21 is provided with four raised lines 24 with protuberance 22 relative sides, and the end with the insertion mouth 34 that inserts insulating body 30 is fixed in cap 20 on the insulating body 30; And protuberance 22 is provided with a little insulator 25, and this little insulator 25 roughly is strip, and its end is provided with elastic portion 250, and this elastic portion 250 roughly takes the shape of the letter U, and little insulator 25 can insert in the square aperture 33.Certainly, fixing also available other form of cap 20 and insulating body 30 realizes, as establishing button hook by raised line, or realizes that by interference engagement between interference engagement between raised line and the insertion mouth 34 or plate body and the pothole at this moment, raised line can play guiding.
