Background technology

Use the circuit breaker of band plug-in type annex (also known as plug-in system) commonplace in the market, its structure is simple, has easy for installationly become the principal element that user selects it.But, the serviceability of circuit breaker is affected with plug-in type annex easily makes the temperature of circuit breaker raise fast, in order to reduce the temperature rise of band plug-in type annex circuit breaker, generally adopt fall appearance namely reduce electric current use way solve, the method not only reduces the cost performance of product, product price is obviously increased, and the volume of product obviously increases, be unfavorable for the requirement of circuit breaker to miniaturization.

In prior art, as Chinese utility model patent Authorization Notice No. CN204155799U discloses one " breaker of plastic casing of band heat sinking function ", it comprises breaker body and plug-in type annex, feature is: described breaker body or plug-in type annex are equipped with heat abstractor, described heat abstractor comprises heat radiation row and at least one fin, and fin is that pectination is contained on heat radiation row side by side.This external plug-in type heat abstractor, the area of dissipation of circuit breaker is increased by the heat-conducting effect of external fin, to arrive the object of cooling, although structure is simpler, but cost is very high, and owing to having added fin, the installing space of circuit breaker is increased, so add use limitation undoubtedly when reality uses.It can thus be appreciated that the volume because of heat abstractor increases and directly causes the increase as plug-type low-pressure plastic shell circuit breaker volume, and this and current circuit breaker more and more trend towards miniaturized developing direction and run counter to.

In view of above-mentioned prior art, how radiating effect excellent with find rational balance point to become industry to pay close attention between the overall volume effectively reducing heat abstractor and expect the technical problem that solves.For this reason, the applicant has made actively good try, and find a way to resolve the problem, technical scheme described below produces under this background.

Summary of the invention

Top priority of the present utility model is to provide a kind of structure simply, conveniently to install, is easy to the plug-in system with radiating effect of realization, it effectively can reduce the temperature of Plug Division, guarantee the serviceability of circuit breaker internal parts, be conducive to again remarkable reduced volume to meet the requirement of circuit breaker miniaturization simultaneously.

Another task of the present utility model is also to provide a kind of circuit breaker, this circuit breaker can ensure there is radiating effect plug-in system described in comprehensive embodiment of technique effect.

For completing top priority, technical scheme provided by the utility model is, a kind of plug-in system with radiating effect, comprise plug in support, connector assembly and case, described connector assembly comprises plug and to be fixedly installed in described plug in support and can the socket of inserting with described plug, described plug in support all offers binding post chamber in Plug Division, arbitrary pole, line two ends, described binding post chamber offers open slot respectively at the two ends of length direction, described socket is contained in described binding post chamber, described case snaps in binding post chamber downwards from the top of plug in support, this case offers the through hole for communicating with binding post chamber at the crown center of short transverse, described case is also formed with radiator structure respectively on the side, two ends of length direction, this radiator structure communicates with the open slot at two ends, binding post cavity length direction.

In a specific embodiment of the present utility model, described radiator structure is directly be opened in the gas outlet on side, case length direction two ends, and there is multiple and interruption-like distribution described gas outlet.

In another specific embodiment of the present utility model, the shape of described gas outlet is strip, poroid or arc shape.

In another specific embodiment of the present utility model, described case has bayonet socket on the side, at least side at length direction two ends, and described base is corresponding in binding post chamber the draw-in groove be provided with for engaging with described bayonet socket.

For completing another task, technical scheme provided by the utility model is, a kind of circuit breaker, comprises and has the plug-in system with radiating effect recited above, and comprising the breaker body patching with this plug-in system and coordinate, described plug is arranged on described breaker body.

The utility model is due to after employing said structure, the beneficial effect had: after fuser belt plug-in system, temperature rise mainly concentrates on the junction of socket and plug, the technical program by arranging radiator structure on case, both degree of protection requirement can be met, effectively reduce again the temperature rise using plug-in system to bring, guarantee that circuit breaker internal parts can normally use, this radiator structure can not increase the volume of plug-in system simultaneously, the requirement of circuit breaker miniaturization can be met, compared with prior art improvement effect is obvious, and structure is simple, easy for installation, be easy to realize.
