Above-mentioned insulating body 10 is provided with the two relative up and down

fishplate bars

11,12 that separate in its front end face, for forming a Plug Division, such relative up and down

fishplate bar

11,12 default location notchs, for the row's of inserting terminal 40 and row's terminal 50 respectively down, and make the

terminal pin

41,51 of such terminal prepare the location by the rear end drawdown; Then be provided with a central indentation 13 along its end face, entreat the body end face of recess 13 both sides to be provided with guide groove 14 hereinto near place, the back side; Its front end face and Plug Division intersection then are provided with recessed rail 15 in both sides, and the lower fastening groove 17 that central slot 16 and two separates on; The back side of whole insulating body 10 then forms a recessed space 100, as shown in Figure 4, two corners, interior top in this recessed space 100 are provided with jack 18, and hypomere with each on row's terminal 40 and down row's terminal 50 each relative anchor point then be provided with interval in a row folder ditch 19.

20 of metal-backs are made as hollow bushing-like in above-mentioned, for being sleeved on above-mentioned relative up and down

fishplate bar

11,12 formed Plug Divisions, shell fragment 21 is preset in its both sides, and upper end inserted sheet 22 is inserted in central slot 16 on the body later on, and its posterior end then is connected to body lower fastening groove 17 with grounding leg 23.
