Description

plastic junction box

technical field

The utility model relates to a plastic junction box, in particular to a plastic junction box used for power supply wiring of an elevator traction machine.

Background technique

At present, the power supply of the elevator traction machine needs to be wired in an insulated junction box, but the junction box currently applicable is composed of an ordinary box body and a box cover. Since the box body volume cannot be made too large, so It is not particularly convenient to carry out the wiring operation in the box body, which greatly reduces the wiring work efficiency of the traction machine.

Utility model content

The purpose of the utility model is to provide a plastic junction box. Its structure is more convenient for wiring operation, which can improve the working efficiency of wiring.

The technical scheme of the utility model: a plastic junction box, which is characterized in that it includes a bottomless box body and a box cover made of plastic; the bottom of the bottomless box body is provided with two lugs distributed on both sides; Notches are provided on the side walls where the two long sides of the bottom box body are located, and ribs corresponding to the notches are provided on the box cover; Wire holes; the four corners of the bottomless box body are provided with first screw holes, and the box cover is provided with second screw holes corresponding to the positions of the first screw holes.

In the plastic junction box above, the lugs are provided with a box body fixing hole and a connection terminal fixing hole, and the connection terminal can be fixed across the two lugs.

In the aforementioned plastic junction box, corresponding limit notches are provided on the gaps of the ribs and the bottomless box body, which can prevent misalignment of the bottomless box body and the box cover during installation.

Compared with the prior art, the utility model provides a larger operating space when the box cover is opened by providing a gap on the bottomless box body, so the operation is more convenient and the efficiency of the wiring work is correspondingly improved. Moreover, the utility model has the advantages of simple structure, convenient installation, good heat dissipation effect, and comparatively saving raw materials.
