Abstract
The utility model relates to a junction box, and particularly relates to an explosion-proof junction box. The explosion-proof junction box comprises a casing body and a cover body which is arranged on the casing body. An outer thread is arranged on the peripheral wall of the upper end of the casing body. An inner thread which is matched with the outer thread is arranged on the inner wall of the cover body. According to the utility model, the outer thread is skillfully arranged on the casing body and the inner thread is arranged on the cover body; a joint face can be hidden beneath the cover body; a waterproof effect is realized; and the protection performance is improved.
Description
Technical field
The utility model relates to a kind of terminal box, relates in particular to a kind of anti-explosion terminal box.
Background technology
The existing product structure has 3 kinds: 1, plane explosion separation structure; 2, seam explosion separation structure; 3, threaded flame-proof type structure (housing is internal thread, and lid is external screw thread).Though above-mentioned 3 kinds of constructed products can both satisfy requirement of explosion proof, barrier propterty (dustproof, waterproof) exists not enough, easily intakes as the rainy day.Existing product threaded flame-proof type structure (housing is internal thread, and lid is external screw thread), outside flameproof joint is exposed to, easily water inlet.
Summary of the invention
In order to address the above problem, the utility model provides a kind of structure relative advantages of simple, the anti-explosion terminal box that barrier propterty is good.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of anti-explosion terminal box, comprise housing and the lid that is arranged on the housing, described housing upper end periphery wall is provided with external screw thread, and described cover body is provided with the internal thread that is complementary with described external screw thread.
As preferably, the upper surface of above-mentioned housing is provided with sealing ring.
The utility model is provided with external screw thread and is provided with internal thread at lid at housing cleverly, its composition surface can be hidden in the lid below, has reached the effect of difficult water inlet, has improved barrier propterty.
