a wiring foot rest for a bus duct jack box comprises two mounting foot pieces which are symmetrically arranged with each other, and an elastic sheet, a contact plate, a middle partition plate and a ceramic baffle plate which are sequentially arranged between the two mounting foot pieces and are extruded and fixed by the two mounting foot pieces; the contact plate comprises a contact plate body, a first bending part is arranged towards the elastic piece from the lower side of the contact plate body, a second bending part is arranged from the first bending part to one side of the ceramic baffle plate, a semicircular contact point is bent from the second bending part, and finally a third bending part is bent outwards from the contact point and is convenient to contact with a bus duct copper bar, and an elastic butt joint end is punched through numerical control on the second bending part.

Preferably, the upper end of the contact plate body is punched with a mounting hole and a wiring hole through numerical control.

Preferably, the number of the mounting holes is four.

Preferably, the elastic sheet comprises an elastic sheet body with the middle part protruding outwards, and a ceramic filler strip is arranged at the protruding part of the elastic sheet body.

Preferably, the ceramic filler strip is provided with a screw hole.

Preferably, the length of the intermediate partition is half of the length of the ceramic baffle.

The utility model discloses technical effect mainly embodies in following aspect: this wiring foot rest has first kink, second kink, contact point and third kink through bending the lower extreme of contact plate body in proper order, when the grafting bus duct copper bar, can cooperate the shell fragment to carry out the first contact through contact point and bus duct copper bar, treat that the bus duct copper bar gets into inside back, cooperate elasticity butt end and bus duct copper bar again and carry out the second contact, be favorable to avoiding because of the unable circumstances of circular telegram of contact point and bus duct copper bar contact failure.
