Description

Heavy-current electrified jack box

Technical Field

The utility model relates to a heavy current electrified jack box.

Background

Modern high-rise buildings and large workshops need huge electric energy, and safe and reliable conduction equipment needs to be selected in the face of the huge load needing hundreds of thousands of amperes of strong current, so that a bus system is a good choice. The bus duct system is a power distribution device for efficiently transmitting current, and particularly meets the requirements of economic and reasonable wiring of higher and higher buildings and large-scale factories. The Bus duct is a new circuit type developed by the united states and called "Bus-Way-System" and is a new conductor formed by using copper or aluminum as a conductor, using a non-olefinic insulating support, and then being installed in a metal groove.

Nowadays, the wiring system is indispensable for electrical equipment and power systems in high-rise buildings, factories, and the like. Due to the needs of various building electric powers of buildings, factories and the like, when the electric energy in the bus duct needs to be taken, the electric energy in the bus duct needs to be led out by using the jack box. Moreover, the jack box is often heavy, so that the jack box needs to be locked in the bus duct, but the traditional locking mode is not simple and convenient enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and providing a large-current electrified jack box.

A high-current live jack box comprises a plug-in type jack box arranged at the upper end of a bus duct; the top end of the bus duct is provided with an L-shaped live connection box, the left end of the plug-in type jack box is provided with a connection port matched with the live connection box, and two sides of the top end of the bus duct are provided with L-shaped bulges; the bottom of the plug-in type plug-in box is provided with a plurality of transverse chutes which are symmetrically arranged, pulley blocks are arranged in the chutes, and each pulley block comprises a baffle and an L-shaped main frame; the L-shaped main frame is matched with the L-shaped bulges, the cross section of the top of the L-shaped main frame is matched with the sliding groove, two sides of the top end of the L-shaped main frame are respectively connected with a sliding block protruding outwards, the sliding groove is provided with a sliding rail matched with the sliding block, the bottom of the L-shaped main frame is connected with a pulley, and the outer wall of the pulley is abutted against the side wall of the bus duct; the baffle is connected to the opening of the sliding groove, the baffle is screwed with a locking screw through threads, the tail end of the locking screw abuts against the side wall of one side of the L-shaped main frame, and the side wall of the other side of the L-shaped main frame abuts against a return spring.

Preferably, the number of the locking screws is two.

Preferably, the number of pulley blocks is 4.

Preferably, the pulley is made of hard aluminum alloy, and a silica gel protective layer is coated on the surface of the pulley.

Preferably, the locking screw is embedded in the sliding groove.

Has the advantages that:

different from the traditional jack box, the device adopts a pulley block form, on one hand, the jack box is ensured not to slide off the bus duct by matching the L-shaped main frame with the L-shaped bulges; on the other hand, through the form of assembly pulley, reduce the frictional force between jack box and the bus duct for the removal of jack box is more laborsaving.

When the plug-in type plug-in box is used, power failure is not needed, the locking screws are firstly loosened, the L-shaped main frame slides outwards under the action of the reset springs until the distance between the pulleys is greater than the width of the L-shaped protrusions, and the plug-in type plug-in box is placed into the bus duct in the vertical direction at the moment. And then the L-shaped main frame is pushed inwards in a mode of rotating the locking screws until the pulleys are abutted against the side wall of the bus duct, and the connection between the plug-in type jack box and the bus duct is completed at the moment.

And pushing the plug-in type jack box along the position of the live connection box until a connector inside the plug-in type jack box is clamped with the live connection box, and finishing the whole installation of the plug-in type jack box at the moment.
