Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a forward and reverse junction box applied to an electromagnetic propulsion system. Background Art

[0002] The junction box is one of the electrical auxiliary materials that protects and connects wires in home decoration. The wires used for decoration pass through the wire tube, and the junction box is generally used as a transition at the joint of the wire (for example, the line is long, or the wire tube needs to turn a corner). However, due to the structural deficiencies of the traditional junction box, the winding is complicated when wiring in the forward and reverse directions, and it is easy to leak electricity and get water in. It is neither convenient nor safe, and the efficiency and life of the use are greatly reduced.

[0003] It can be seen that wiring efficiency and sealing are two extremely important factors that limit the development of junction boxes. Whether the problems of low wiring efficiency and weak sealing of junction boxes can be effectively solved has become the key to making the junction boxes more convenient to use, with a wider range of applications and a longer service life.

[0004] Therefore, improving the wiring efficiency and sealing of the junction box is of great significance to achieving efficient use of the junction box. According to a circuit-breaking safety junction box provided by publication number: CN208046562U, the proposed circuit-breaking structure can make the junction box safer to rescue in case of danger, but it does not take into account that it can only facilitate one-way wiring. When wiring in reverse, the wiring space will be larger, and the installation and use efficiency will be lowered. Utility Model Content

There is one forward wiring hole and one reverse wiring hole on the box body, which can facilitate the wiring when forward wiring or reverse wiring, reduce space, and lock the wires, greatly improving the use efficiency.

[0010] Furthermore, the sealing member is a sealing ring, and the sealing ring is arranged on the card slot.

[0011] Furthermore, the surfaces of the box body and the box cover are coated with waterproof and anti-corrosion coatings.
