Abstract
The utility model discloses a kind of explosion-proof wiring box, comprise casing and case lid; Described casing is provided with several binding posts and ground connection label, and in casing, middle part is provided with earthing bar, and in casing, afterbody is provided with fixed via, and fixed via both sides are provided with coil block, and in casing, the remaining space of afterbody is filled with epoxy resin; The junction of described casing and described case lid is flameproof joint, flameproof joint is provided with sealing strip.The utility model, by optimizing overall structure, ensures electrical characteristic and the explosion-resistance characteristic of explosion-proof wiring box, can adapt to compare rugged environment condition, have stronger stability.
Description
Technical field
The utility model relates to technical field of electric control, is specifically related to a kind of explosion-proof wiring box.
Background technology
Explosion-proof wiring box is a kind of range of application electric elements more widely, can be used for, in 380 and following circuit, being used as various electrical apparatus interstar connection, separated time.Existing explosion-proof wiring box install inconvenient, use limitation comparatively large, mechanical performance is poor, can not adapt to comparatively rugged environment condition.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the utility model provides a kind of explosion-proof wiring box, ensures electrical characteristic and the explosion-resistance characteristic of explosion-proof wiring box, can adapt to compare rugged environment condition, have stronger stability.
Technical scheme: explosion-proof wiring box described in the utility model, comprises casing and case lid; Described casing is provided with several binding posts and ground connection label, and in casing, middle part is provided with earthing bar, and in casing, afterbody is provided with fixed via, and fixed via both sides are provided with coil block, and in casing, the remaining space of afterbody is filled with epoxy resin; The junction of described casing and described case lid is flameproof joint, flameproof joint is provided with sealing strip.Fixed via and coil block are set, are beneficial to and are connected with control element; Filling epoxy resin, there is good physics, chemical property, to the surface of metal and nonmetallic materials, there is excellent adhesive strength, dielectric property are good, satisfactory mechanical property, ensure electrical characteristic and the explosion-resistance characteristic of explosion-proof wiring box, can adapt to compare rugged environment condition, there is stronger stability; Earthing bar the reliability that can ensure casing ground connection is set.
Improve technique scheme further, described flameproof joint is also provided with antirust oil coating.Antirust oil coating is set, the mechanical damage of flameproof joint can be reduced, improve stability.
In order to ensure being fixedly connected with of wire, described binding post adopts the inside spin self-locking type connecting terminal of 2.5 ~ 3.5mm specification.
Described binding post is 5, and wherein on described casing, both sides arrange 2 respectively, is provided with 1 at described bottom half.The position of binding post, number, direction all can be arranged according to user's request, are not limited to the preferred version that the utility model provides.
One or two in described binding post are provided with closure plate.Untapped binding post uses closure plate to seal, and guarantees overall explosion-proof performance.
Described casing and case lid adopt stainless steel to make, each other by being weldingly connected.
Described sealing strip adopts acrylonitrile-butadiene rubber to make.Adopt the sealing strip that acrylonitrile-butadiene rubber is made, oil resistant, ageing resistace are good.
Beneficial effect: compared with prior art, advantage of the present utility model: the utility model, by optimizing overall structure, ensures electrical characteristic and the explosion-resistance characteristic of explosion-proof wiring box, can adapt to compare rugged environment condition, have stronger stability; The reliability that earthing bar ensures integral ground is set; Binding post has good mechanical features, and can arrange according to user's request.
Accompanying drawing explanation
