Abstract
The utility model discloses a kind of miniature circuit breaker, it is related to electrical equipment, the crescent disc type design of the miniature circuit breaker can be effectively increased miniature circuit breaker and installing plate contact surface, can improve the installation steadiness of miniature circuit breaker.Adjacent breaker body can be caught in the arc notch of circuit breakers body, then be fixed breaker body on a mounting board when needing multiple breakers to be mounted side by side by bolts through bolt holes, can connected the miniature circuit breaker being mounted side by side and more fasten.
Description
Technical field
The utility model is related to electrical equipment, relates in particular to a kind of miniature circuit breaker.
Background technology
Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition, and miniature circuit breaker is mainly used in industry, business, height
The various places such as layer and residential houses.Existing miniature circuit breaker is designed to long and narrow vertical bar shape mostly, causes miniature open circuit
Device and installing plate contact surface are too small and install unstable, and the miniature circuit breaker that same row installs connects not tight enough each other
Gu, come off so as to cause breaker can be easily separated.
Utility model content
The utility model increases the installation of miniature circuit breaker mainly solving the technical problems that provide a kind of miniature circuit breaker
Steadiness, connects the miniature circuit breaker being mounted side by side and more fastens.
To achieve the above object, the utility model provides following technical scheme：A kind of miniature circuit breaker, its feature exists
In：The miniature circuit breaker includes the breaker body of crescent, and breaker body side is provided with arc notch, and arc notch
Diameter it is equal with the diameter of breaker body, breaker body front be provided with switchblade knife, if breaker body is surrounded by
Dry screw hole.
Beneficial effect using above technical scheme is：The crescent disc type design of the miniature circuit breaker can be effectively increased
Miniature circuit breaker and installing plate contact surface, can improve the installation steadiness of miniature circuit breaker.When the multiple breakers of need are mounted side by side
Adjacent breaker body can be caught in the arc notch of circuit breakers body, then by bolts through bolt holes by open circuit
Device body is fixed on a mounting board, can connect the miniature circuit breaker being mounted side by side and more fasten.
Brief description of the drawings
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation of miniature circuit breaker of the utility model；
Fig. 2 is a kind of constitutional diagram of miniature circuit breaker of the utility model.
Wherein, 1- breaker bodies, 2- arc notch, 3- switchblade knives, 4- screw holes.
Embodiment
Describe a kind of preferred embodiment of miniature circuit breaker of the utility model in detail below in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2 show a kind of embodiment of miniature circuit breaker of the utility model：The miniature circuit breaker includes the moon
The breaker body 1 of thread form, the side of breaker body 1 is provided with arc notch 2, and the diameter and breaker body 1 of arc notch 2
Diameter it is equal, the front of breaker body 1 is provided with switchblade knife 3, and breaker body 1 is surrounded by some screw holes 4.This is miniature
Breaker is applied to exchange 50/60Hz rated voltage 230/400V, the overload and short-circuit protection of rated current to 63A circuits it
With, can also under normal circumstances as circuit infrequently operation conversion be used.
With reference to Fig. 1 and Fig. 2, the crescent disc type design of the miniature circuit breaker can be effectively increased miniature circuit breaker and installation
Plate contact surface, can improve the installation steadiness of miniature circuit breaker.Can be by adjacent breaker when needing multiple breakers to be mounted side by side
Body 1 is caught in the arc notch 2 of circuit breakers body 1, then is fixed breaker body 1 by bolts through bolt holes 4
On a mounting board, because the diameter of arc notch 2 is equal with the diameter of breaker body 1, breaker body 1 can be closely caught in
In the arc notch 2 of adjacent miniature circuit breaker, it can connect the miniature circuit breaker being mounted side by side and more fasten.
The above is only preferred embodiment of the present utility model, it is noted that for one of ordinary skill in the art
For, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
