Embodiment Construction

[0018] Such as figure 1 As shown, the present invention mainly includes a junction box seat 1, a junction box cover 2 installed above the junction box seat 1, a first explosion-proof threaded hole 3 is provided at the front end of the junction box, and an explosion-proof grenade is arranged at the first explosion-proof threaded hole 3. The head 4 is used as a cable joint, and the inner cavity of the junction box is a square structure with a large space, which has a large space for cable turning. Compared with the previous circular cavity junction box, the connection space is increased by about 20-30%.

[0019] combine figure 2 and image 3 , the junction box base 1 and the molded plastic plate 6 that is poured into it together form an integral wiring device 7, the junction box also includes a connecting bolt 5 passing through the integral wiring device 7, and the connecting bolt 5 is provided with a nut for fixing the user's cable , flat pads and spring pads, the junction b...

Abstract

The invention discloses an explosion-proof type junction box. The explosion-proof type junction box comprises a junction box seat and a junction box cover mounted on the upper part of the junction box seat, wherein a first explosion-proof threaded hole is formed in the front end of the junction box. The junction box also comprises a cable joint mounted at the position of the first explosion-proof threaded hole and a junction bolt mounted on the junction box seat, and a component for fixing a user cable is arranged on the junction bolt. The explosion-proof type junction box is characterized in that an integral junction device is formed by the junction box seat together with a mold plastic plate integrally poured with the junction box seat; and the junction bolt passes through the integral junction device. According to the explosion-proof type junction box, the mold plastic plate is integrally poured with the junction box seat to form the integral junction device, so that the quantity and area of explosion-proof joint surfaces are reduced, and the explosion-proof effect is good.

Description

technical field [0001] The invention relates to the technical field of accessories for explosion-proof motors, in particular to an explosion-proof junction box that can be used in an explosive gas environment. Background technique [0002] In the prior art, the junction box used for the main power supply of an explosion-proof motor generally adopts a junction bolt and a terminal cover to set a flameproof joint surface, and leads out through a hard connection to meet the requirements of the flameproof, but in this structure, the terminal sleeve is placed on the junction box seat. The fixing on the top often produces more joint surfaces, and the explosion-proof effect is not ideal. And limited by the cavity size of the junction box, the operating space is small and the manufacturability is relatively poor. [0003] The Chinese patent with the application number 201610451424.9 discloses a large-space four-stage explosion-proof junction box. Although this patent application sol...
