Abstract
The utility model discloses a small circuit breaker contact device which comprises a bracket. One end of the bracket is a clamping part which is internally embedded with a current carrier. The resistivity of the current carrier material is smaller than 2.510-8 omegam at a temperature of 20 degrees. According to the small circuit breaker contact device, through the bracket which provides supporting and force transduction effects, the clamping part of the bracket is embedded with the current carrier, the respective material requirement of the bracket and the current carrier is satisfied respectively, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of electric equipment, is specifically related to a kind of miniature circuit breaker contact apparatus.
Background technology
Contact device for circuit breaker comprises power transmitting portions and the current-carrying part of one each other.The power transmitting portions plays a part to support and the power conduction; Current-carrying part plays conduction current, and its conductivity directly determines the conducting function of contact.For making contact have good conducting function and mechanical function, current-carrying part need adopt the material that conductivity is strong, the power transmitting portions need adopt the material of good mechanical property, under prior art, due to the power transmitting portions of contact device for circuit breaker and current-carrying part one each other, cause the material of the contact device for circuit breaker good mechanical property again that should conduct electricity very well, cause the raising of production cost.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of miniature circuit breaker contact apparatus, to reach the purpose reduced production costs.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of miniature circuit breaker contact apparatus, comprise support, and an end of described support is clamping part, is equipped with carrying object in described clamping part, and the resistivity of described carrying object material is 20 to be less than 2.5*10 while spending in temperature
-8Ω/m.
Preferably, the described carrying object material selection purity copper that is greater than 99%.
By technique scheme, the utility model, by the support of support and power conduction is provided, is set carrying object on the clamping part of support, meets respectively support and carrying object material demand separately, greatly reduces production cost.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
Fig. 1 is the structural representation of the disclosed a kind of miniature circuit breaker contact apparatus support of the utility model embodiment;
Fig. 2 is the structural representation of the disclosed a kind of miniature circuit breaker contact apparatus carrying object of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Fig. 1 and Tu, a kind of miniature circuit breaker contact apparatus, comprise support, and an end of support is clamping part 1, and 1 li of clamping part is equipped with carrying object, and according to actual needs, the material of carrying object is that 20 resistivity while spending are less than 2.5*10 in temperature
-8Ω/m, and the actual copper of selecting purity to be greater than 99% of carrying object material.
Of the present utility model effect of erecting support and power conduction, carrying object electrifies and spreads the effect of leading, actual when selecting material, above-mentioned two-part material does not need to have both simultaneously all good advantages of electric conductivity and mechanical performance, support only need be selected the material of good mechanical property, carrying object only need to be selected the material conducted electricity very well, and has so just reduced greatly production cost.
Above-described is only the preferred implementation of a kind of miniature circuit breaker contact apparatus disclosed in the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
