A kind of cubicle handcart

Abstract

The utility model discloses a kind of cubicle handcart, the cubicle handcart includes chassis car, the chassis car is equipped with several solid seal pole, the upper and lower of the solid seal pole is equipped with upper movable contact, lower movable contact respectively, the upper movable contact, lower movable contact is fixed with the clamping assembly for clamping movable contact, the clamping assembly includes the support frame of opposite setting, limiting heat-conducting plate, the both sides of the support frame are equipped with the clamping piece movable to two sides direction, the clamping piece is equipped with several equidistant grooves at the part of departing from clamping portion. Through limiting heat-conducting plate card and set embedded clamping piece, increase contact area, improve heat conduction efficiency;Heat-conducting part is embedded into groove, further strengthen heat exchange, reduce clamping piece temperature rise, guarantee stable operation under high return circuit current, prevent insulation performance deterioration;Optimize its heat distribution and reduce local overheating through structure, prolong the life of movable contact and related components, improve the overall reliability of equipment.
