Abstract
The utility model relates to a breaker, in particular to an active contact for a small breaker, comprising a contact body and a contact point, characterized in that: the other piece of a conductive metal is arranged at the contact position between the contact body and the static contact to form a contact point. The utility model has the advantages that: an contact end of the contact is provided with another conductive metal to improve conductive function, which can have better protection result when current is in a short circuit; in addition, the contact end face of the contact point is shown as an arch shape, which improves contact function, lowers temperature rising and has strong controlling arch.
Description
Technical field:
The utility model relates to a kind of circuit breaker, relates in particular to a kind of active contact of miniature circuit breaker.
Background technology:
The active contact of present miniature circuit breaker comprises contact body and contact; contact body and contact generally are copper materials; its maximum rated current 63A commonly used of miniature circuit breaker; the about 6000A of maximum short-circuit protection breaking current; the miniature circuit breaker of numerous manufacturer production is failed to reach 6000A and is required index for over ten years at present; electric current excessively is not very smooth in the dynamic/static contact contact; the arc spark that produces is big; circuit breaker occurring through regular meeting burns and trips; easily cause fire; electric conductivity is bad, can not play a very good protection.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of contact performance good, conducts electricity, and effectively controls the active contact of the strong miniature circuit breaker of temperature and arc extinguishing ability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the conducting metal that has been sticked in addition on contact body and fixed contact position contacting constitutes the contact.
Further setting of the present utility model is: described contact contact end face is curved.
Useful technique effect of the present utility model is: the conducting metal that has been sticked in addition on contact body and fixed contact position contacting constitutes the contact; improved electric conductivity; can when short circuit current, play the better protection effect like this; secondly; the curved such contact performance that improved of contact contact end face; temperature rise reduces, and the arc extinguishing ability is strong.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is the structural representation of the active contact of the utility model miniature circuit breaker
Fig. 2 is the cross-sectional view of Fig. 1
Embodiment:
As shown in Figure 1, the active contact of miniature circuit breaker, the contact body 1 that copper spare forms by punching press, on contact body 1 and fixed contact position contacting, be provided with and contact the curved conductive metal contact 2 of end face 21 by chimeric, some seam, riveted split, the conductivity of contact is better than the conductivity of copper, but the present ordinary circumstance of the electric conducting material that is sticked is silver material, certainly in this practicality, also can be the conducting metal of other materials, as golden material, though the electric conductivity of gold is good, but consider production cost, ordinary circumstance does not adopt.
Claims (2)
1, a kind of active contact of miniature circuit breaker comprises contact body and contact, it is characterized in that: the conducting metal that has been sticked in addition on contact body and fixed contact position contacting constitutes the contact.
2, the active contact of miniature circuit breaker according to claim 1 is characterized in that: described contact contact end face is curved.
