Therefore, be necessary to design a kind of novel socket connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of socket connector, and it can be connected with multiple voice plug, and is compatible good, is convenient to make, and can reduce cost, and higher economic and practical is arranged.

For achieving the above object, the utility model socket connector comprises two identical main bodys and back plug, and wherein, two main bodys can be inserted in the plug of back side by side, and each main body comprises insulating body and is contained in conducting terminal in the insulating body.

Compared with prior art, the utility model socket connector, it can be connected with multiple voice plug, and is compatible good, is convenient to make, and can reduce cost, and economical with materials has higher economic and practical.。

[embodiment]

Below in conjunction with the drawings and specific embodiments electric connector of the present utility model is described further.

See also Fig. 1 to Fig. 6, the utility model socket connector is used for and docks electronic building brick (as electronic building bricks such as butt joint voice plugs) and cooperate, comprise two identical main bodys 1 and back plug 2, metal shell 3, wherein two main bodys 1 can be inserted in the back plug 2 side by side, and each main body 1 comprises insulating body 10 and is contained in the row of three in the insulating body 10 conducting

terminal

11,12,13, cap 14, earth terminal 15.

Wherein, metal shell 3 comprises front 30, and end face 31, left surface 32 and the right flank 33 that extend 30 top, the left and right sides from the front, and end face, left surface and right flank are all perpendicular to the front.Front 30 is provided with six holes 34, and face lower end, left and right sides extension downwards respectively is provided with pin 35, to insert circuit board (not drawing among the figure).

Insulating body 10 front surfaces form three inside recessed square potholes 100 side by side, and each pothole substantial middle position extends internally and forms a circular spliced eye 101, insert for butt joint voice plug, circular spliced eye upside is connected with a square aperture 102, and each pothole roughly corner location is provided with insertion mouth 103.

Cap 14, comprise a square plate body 140 and the protuberance 141 that extends forward from square plate body, protuberance roughly is hollow cylindrical, its hollow part forms a circular butt hole 142, run through square plate body, the relative side with protuberance of square plate body is provided with four raised lines 143, and the end with the insertion mouth that inserts insulating body is fixed in cap 14 on the insulating body; And protuberance is provided with a little insulator 144, this little insulator roughly is strip, and its end is provided with abutting part, and little insulator can insert in the square aperture, this butt joint electronic building brick can compress by the abutting part with little insulator, touches another conducting terminal after forcing a conducting terminal to move.Certainly, fixing also available other form of cap and insulating body realizes, as establishing button hook by raised line, or realizes that by interference engagement between interference engagement between raised line and the insertion mouth or plate body and the pothole at this moment, raised line can play guiding.

Above-mentioned three groups of conducting

terminals

11,12,13 all insert in the insulating body 10, and first group of conducting terminal 11 comprises the signal terminal 110 that is positioned at the left and right sides and be positioned at the contact chip 111 of top.Second group of conducting terminal 12, comprise two roughly L-shaped conducting terminals, comprise that contact site 120 reaches and the perpendicular connecting portion 121 of contact site, wherein contact site 120 is positioned at the top of the contact chip 111 of first group of corresponding with it conducting terminal 11, when moving on the contact chip 111, can be conducted with contact site 120.The 3rd group of conducting terminal 13 also comprises two roughly L-shaped conducting terminals, is positioned at the outside of the signal terminal 110 of first group of corresponding with it conducting terminal 11, and contacts with it; The 3rd group of conducting terminal 13 be arranged in the accepting groove of insulating body 10 and with it the outside of corresponding signal terminal 110 contact, electrically conduct with formation.
