Abstract

The utility model discloses a wire holder, which is characterized in that a clamping plate is also arranged in a clamping point at the lower end of a holder body, a spring is arranged in the clamping plate, a screw is a special-shaped screw, and the special-shaped screw is composed of a screw, an elastic pad and a special-shaped plate. Owing to the clamping plate arranged in the clamping point at the lower end of the holder body of the utility model, the holder can be conveniently dismounted from and mounted on a guide way under the action of the clamping plate and the spring, and a screw rod of the screw penetrates through the upper plate of the special-shaped pad. Even when the screw is separated from conductive components, the screw can not drop, and the utility model is an ideal electric wire holder.

Description

A kind of junction block

The utility model relates to a kind of junction block that is used for electric wiring.

Mostly there is the inconvenient and caducous deficiency of screw of dismounting in junction block of the prior art, the junction block of some imports is installed on the guide rail also more convenient, but then be difficult to junction block is pulled down from guide rail if run into fault, when wiring, screw is unscrewed from the electric-conductor of junction block, accidentally screw will fall, not only be difficult to seek, also may impact safety.

The purpose of this utility model is to provide a kind of improved junction block, and it can carry out dismounting from guide rail comparatively easily, and can guarantee that screw can not fall when wiring.

The technical solution of the utility model is achieved in that a kind of junction block, it mainly comprises pedestal, be located at insulating part, electric-conductor on the pedestal, the screw that can be connected with electric-conductor, be located at the clip that the pedestal lower end can engage with guide rail, it is characterized in that: the clip place in the pedestal lower end also is provided with clamp, and spring is housed in clamp, screw is a special-shaped screw, and this special-shaped screw is made up of screw, bullet pad and profiled spacer.

The utility model is owing to also be provided with clamp at the clip place of pedestal lower end; spring is housed in clamp; under the effect of clamp and spring; junction block can carry out dismounting from guide rail easily; and the screw rod of screw from profiled spacer last slice pass; even screw separates with electric-conductor, screw can not split away off yet, and has set up mark lid and dividing plate in addition; mark sheet is protected; so that the user presses the mark wiring, can not get wrong, can prevent that the workman from operating that mistiming is bumped or foreign matter falls into junction block; and can reduce dust and enter junction block inside; this junction block novel structure, safe and reliable, easy to use.
