Power supply groove 21, the aft bulkhead center of the sliding shoe 3 is provided with the conductive projection 31 being engaged with the power supply groove 21, the cunning
It is located in motion block 3 and slot 34 of the opening towards front end is set at symmetrical axle, the slot 34 is located in the sliding shoe 3 left
Right both sides are respectively arranged with left horizontal concrete chute 38 and right horizontal concrete chute 39, and the left horizontal concrete chute 38 is connected with right horizontal concrete chute 39
And the slot 34 is orthogonal to, left cursor slide 32 and the right side are slidably fitted with the left horizontal concrete chute 38 and right horizontal concrete chute 39 respectively
Cursor slide 33, the left cursor slide 32 and right cursor slide 33 are protruding away from one end of the slot 34 and are provided with extruding inclined-plane, institute
State extruding inclined-plane to be engaged with corresponding skewed slot 23, telescopic chute of the opening towards right cursor slide 33 is provided with the left cursor slide 32
320, it is additionally provided with stopper slot 30, the He of left cursor slide 32 in the front and rear end wall of the left horizontal concrete chute 38 and right horizontal concrete chute 39
Spacing protrusion 36 is provided with the front/rear end of right cursor slide 33, the spacing protrusion 36 is installed in the stopper slot 30, and institute
State spacing protrusion 36 and the stopper slot 30 is also equipped with top pressure spring 37, the top between the inner end wall of the slot 34
Pressing spring 37 is used to the left cursor slide 32 and the top pressure down fold 23 of right cursor slide 33；The rear end face of the plug 1 be provided with it is described
The arcuate conducting prong elements 11 that slot 34 is engaged, and the groove 12 excessively of cross direction profiles is provided with the arcuate conducting prong elements 11.
Valuably or exemplarily, wherein, the left horizontal concrete chute 38 and right horizontal concrete chute 39 are in same level,
And the groove width of the left horizontal concrete chute 38 is more than the groove width of the right horizontal concrete chute 39.
Valuably or exemplarily, wherein, the groove width of the telescopic chute 320 is equal with the width of the right cursor slide 33, from
And the right cursor slide 33 can be made to extend into the telescopic chute 320.
Valuably or exemplarily, wherein, the left hand end wall of the slot 34 is provided with electroconductive elastic sheet 35 positioned at rear end, described
Electroconductive elastic sheet 35 is connected with the conductive projection 31 by electric wire, and the power supply Cao21Yu cities are electrically connected, so as to be led described
