Description
Technical field
The invention belongs to breaker of plastic casing technical field, and in particular to a kind of plug-in type miniature circuit breaker.
Background technology
In the prior art, miniature circuit breaker typically uses standard clamp rail mounting means, specifically the bottom of miniature circuit breaker
Portion is installed in standard clamp rail.Breaker respectively has wire frame up and down, is compressed with mains side, load-side by wire attachment screw.
When product break down, it is necessary to when repairing or changing, first have to deenergization, then remove wire, product is torn open from clamp rail
Under, then new product is installed, then wiring, then the power supply that switches on power.This clamping mode is simple and easy to do, is made extensively
With being main flow instantly.But in this installation process, line powering is discontinuous, power-off time is longer, is not suitable in data
The heart, communication power supply etc. require the industry installation of power supply continuity, remove and repair.Clamped additionally, due to using, though its steadiness
So preferably, but in the case where vibrating more violent environment, or easily it is shifted over or comes off.
Existing plug-in type miniature circuit breaker, all it is the built-in electrical connector socket in the socket of base, in plug-pull type breaker
Evagination is set in module connects electric socket board, and this structure is disadvantageous in that：When carrying out powered hot plug, if producing electricity
Electrical connector socket in chassis interior, easy scaling loss base then substantially occurs for arc spark, and because base is usually that fixation is set
Put, the operation inconvenience of its disassembling, assembling and replacing.
The content of the invention
It is an object of the invention to provide it is a kind of prevent hot plug when electrical arc erosion base plug-in type miniature circuit breaker.
Realizing the technical scheme of the object of the invention is：A kind of plug-in type miniature circuit breaker, including base and plug-in open circuit
Device module；Base includes base housing and two connecting terminal components provided with socket, and the plug-pull type breaker module can insert
That pulls out is arranged in the socket；Plug-pull type breaker module includes module housing, enters electrical socket, goes out electrical socket and for leading to
Break into electrical socket and go out the opening/closing operation mechanism of circuit between electrical socket；Each connecting terminal components include metal framework, wiring
Screw, electrical terminals and connect electric socket board；Electrical terminals include being located at the clamp plate portion of socket both sides and connecing below socket
Electroplax portion；Clamp plate portion and metal framework clamping form clamp hole；The bottom for connecing electric socket board is fixed on and connect in electroplax portion, connects electric mortiser
The top of plate stretches out base housing and in socket；Enter electrical socket and go out electrical socket to be respectively positioned in module housing, enter electrical socket
Electric socket board adaptation each and described in one is connect with electrical socket is gone out.
Such scheme is further preferably：Enter electrical socket provided with one and connect electric socket board adaptation enter electrical slot, go out electricity
Socket be provided with one and connect electric socket board adaptation go out electrical slot.
The present invention has advantages below：（1）It is arranged on by the way that electric socket board will be connect in the socket of base, electrical socket will be entered and gone out
Electrical socket is arranged in plug-pull type breaker module, the structure of traditional plug-in type miniature circuit breaker is improved, now during hot plug
Electric arc substantially base exterior carry out, will not scaling loss base；If electrical arc erosion plug-pull type breaker module, due to its appearance
Easily change, it is also more convenient to safeguard.（2）Plug-pull type breaker module can directly be plugged from the socket of base and installed more
Change, effectively shorten power-off time.
