Problems solved by technology

[0002]Lighting busway is a power distribution device for high-efficiency transmission of current, mainly used in high-rise buildings, hotels, shopping malls, offices, schools, hospitals and other small and medium loads but with many branches The lighting system and the place where the electricity is used. The plug box is a part of the bus duct. Generally, the two elastic inserts used for the pins of the bus duct are fixed on both sides of the main insert by multiple bolts. The stability is poor. The two elastic The inserts are easy to shift and skew relatively, and it is easy to cause a short circuit due to excessive temperature rise of the pins, poor stability, and even cause the device to burn out in severe cases

Abstract

The invention relates to a pin for an illuminating bus duct plug box. The pin comprises an elastic part, a supporting column and a base. An elastic base of the elastic part is fixed in an elastic part clamping groove of the supporting column in a clamping mode, and the supporting column is fixed in a supporting column clamping groove of the base in a clamping mode. The elastic part, the supporting columns and the base are fixed into a whole through bolts. The pin for the illuminating bus duct plug box is simple in structure, good in stability, firm in plugging, safer and more reliable. Meanwhile, cost is further lowered.

Description

technical field [0001] The invention relates to a pin used for a plug-in box of a bus duct, which belongs to the technical field of power transmission. Background technique [0002] Lighting busway is a power distribution device for high-efficiency transmission of current. It is mainly used in high-rise buildings, hotels, shopping malls, offices, schools, hospitals and other lighting systems with small and medium loads but many branches. One part, the two elastic inserts that are generally used for the pins of the bus duct are fixed on both sides of the main insert by multiple bolts, the stability is poor, and the two elastic inserts are easy to shift and skew relative to each other, and it is easy to cause the temperature rise of the pins to exceed the standard It will lead to short circuit, poor stability, and even burn out the equipment in severe cases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plug p...
