A kind of intelligent miniature circuit breaker
This utility model relates to a kind of switchgear, particularly a kind of intelligent miniature circuit breaker.
Along with chopper is to intelligent, the development of automation direction, add on/off switch intelligent electric on existing miniature circuit breaker and drive module, and intelligent driver module needs, at miniature circuit breaker enterprising line end power taking (obtaining power supply by electrical connection) or the electrical quantity of detection voltage, to negate feedback signal etc. at leading-out terminal；Existing conventional small chopper, it is original design not in view of the problem of above-mentioned connecting lead wire.
Intelligent driver module electricity-fetching method mainly has three kinds at present:
First method, outside turnover line end from miniature circuit breaker, intelligent driver module is accessed to wire, thin electric wire need to be locked one by one when this method is tested when plant produced, during to user side, main loop cabling need to together be accessed little disconnected crimp type terminal together with thin electric wire by user, assembles loaded down with trivial details, actually used middle may get the fault of existing intelligent driver module because of terminal block reason；
Second method, inside miniature circuit breaker, spot welding or soldering from its electric-conductor, thin electric wire is passed from shell, then accessing intelligent driver module, this kind of method needs thin wire through shell, and efficiency of assembling is low, maintenance after final assembly completes is inconvenient, and the effect of intrinsic advantage modularized design is had a greatly reduced quality；
The third method, its representative is the overvoltage/undervoltage miniature circuit breaker of ABB AB, elastic spring is utilized end of incoming cables and the leading-out terminal of miniature circuit breaker to be electrically connected with intelligent driver module respectively, solve the subproblem of above two method, but its elastic spring gets too close to binding post, user is inconvenient when carrying out installing main loop cabling, is in the position of binding post test fixture due to its elastic spring again, after final assembly, miniature circuit breaker can not carry out adjustment again.
In view of this, the present inventor's especial manufacture go out a kind of can be by the intelligent miniature circuit breaker of intelligent driver module Yu miniature circuit breaker modularization assemble, its dismounting is more convenient, and circuit is simple, the wiring of intelligent driver module does not affect the cable of other parts of chopper and installs, and this case thus produces.
Utility model content
The purpose of this utility model is to provide a kind of intelligent miniature circuit breaker, realize intelligent driver module and miniature circuit breaker modularization assemble, the wiring of intelligent driver module is simpler, dismounts more convenient, it is to avoid the problem that the cable of effect of connection other parts of chopper of intelligent driver module is installed.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of intelligent miniature circuit breaker, including breaker body and intelligent driver module, intelligent driver module is arranged on breaker body side, it is respectively mounted input terminal and outlet terminal inside described breaker body two ends, with formation inner groovy outside the breaker body corresponding to input terminal and outlet terminal, jack is offered below inner groovy, the internal wiring end of elastic spring inserts inside breaker body from jack, and the internal wiring end elasticity of elastic spring connects inlet wire cross-talk and outlet terminal, elastic spring external terminal extend out to inner groovy from jack, intelligent driver module connects elastic spring external terminal by a thin wire along inner groovy.
Each installation one case on the inner groovy at described breaker body two ends.
Forming grab inside described case, inner groovy cell wall forms draw-in groove, and case snaps in draw-in groove by grab and fastens in breaker body.
The internal wiring end of described elastic spring is the elastic joint part at least provided with an elastic bumps, and the external terminal of elastic spring is bending connecting portion.
Described input terminal and outlet terminal have the elastic joint part with elastic spring and coordinate hole or the pit of location.
Described breaker body is 2 poles or 2 above choppers, each breaker unit is the most assembled, the inner groovy of all breaker units connects into an elongated cavity, one wiring board is installed in elongated chamber body, on wiring board, connecting hole is offered in the position of corresponding each inner groovy jack, the elastic spring of each breaker unit is plugged on the connecting hole of wiring board respectively
Described elastic spring external terminal is inserted and is welded on the connecting hole of wiring board.
After using such scheme, this utility model offers inner groovy at the breaker body two ends of driver, elastic spring is arranged in the jack below inner groovy, thin wire is utilized to connect elastic spring external terminal, thus realize intelligent driver module and input terminal and the wiring of outlet terminal, the interference of adjustment holder contacts position below elastic spring and intelligent driver module pair of connecting wires is avoided with this, do not affect the adjustment of chopper, and, elastic spring of the present utility model is connected with input terminal and outlet terminal elasticity, quick detachable, intelligent driver module is the most quick detachable with elastic spring, make intelligent driver module, can quick-assembling and fractionation between elastic spring and breaker body structure, realize modularization assembling.
