Description

A kind of improved breaker plastic casing

Technical field

The utility model belongs to breaker technical field, is related to a kind of plastic casing, and in particular to a kind of improved open circuit Device plastic casing.

Background technology

Breaker（English name：circuit-breaker）It is to refer to close, carry and cut-off under normal loop condition Electric current, and can close, the switching device of the electric current under abnormal loop condition, breaker are carried and cut-off within the defined time It can be used to distribute electric energy, infrequently start asynchronous motor, the implementations such as power circuit and motor are protected, when they occur When serious overload or short circuit and the failure such as under-voltage can automatic shutdown circuit, its function equivalent to Fuse switch with it is excessively deficient The combination of electrothermal relay etc., and it is latter in disjunction fault current as need not change parts, obtained at present extensive Using.

As shown in Fig. 6, Fig. 7 and Fig. 8, a kind of breaker plastic casing 10 of prior art, including incoming line 101, inlet wire Terminal 102, operation handle 103, outlet terminal 104 and line outlet, wherein incoming line 101, input terminal 102 and line outlet, go out Line terminals 104 are distribution symmetrical above and below, and the inner side of input terminal 102 being entered in enter line side tie-in line insertion incoming line 101 during use In line cavity 40, the incoming line 101 of breaker is fixed on by continuing the tight input terminal 102 of inside sidespin by enter line side tie-in line In, similarly in outgoing line side leading-out wire insertion line outlet in the outlet cavity of the inner side of outlet terminal 104, by continuing inside sidespin Outgoing line side leading-out wire is fixed in the line outlet of breaker by tight outlet terminal 104, is then controlled manually by operation handle 104 The upward combined floodgate and downward separating brake of breaker, realize that breaker can be closed, carried and the beginning is normal or abnormal loop Function.

But found in actual use, incoming line and line outlet usually have the exposure of part metals line because of handling bad Outside, potential safety hazard be present, while input terminal and outlet terminal screw because being metal and must be hidden in plastic casing Needed with when screwing out by supporting instrument, using upper inconvenient, there is also using not in dark surrounds for operation handle in addition Just.

Utility model content

The purpose of this utility model is for overcome the deficiencies in the prior art, and is provided outside a kind of improved breaker plastics Shell, its property esy to use, safe and reliable are high.

What the purpose of this utility model was realized in：A kind of improved breaker plastic casing, including plastic casing sheet Body, the plastic casing body include incoming line, input terminal, operation handle, outlet terminal and line outlet, the incoming line and The outside of line outlet is provided with integrally formed guide wire, the guide wire be along the hole wall of the incoming line and line outlet outward Extend the pipeline configuration that forms, be connected with elastic handle on the outside of the input terminal and outlet terminal, in the operation handle Coated with fluorescent material.

The pipeline configuration is the cylindrical structure that outer end has bell shape.

The length of the pipeline configuration is at least 5mm.

The inner of the elastic handle has cross projection, and the outer end of the input terminal and outlet terminal has relatively The cross groove answered, the elastic handle pass through the cross projection and the mutually nested and inlet wire of cross groove Terminal and outlet terminal link together.

The external diameter of the elastic handle center section is consistent with the external diameter of the input terminal and outlet terminal, described elastic The side of handle outer end portion is provided with anti-skid structure.

The beneficial effects of the utility model are：（1）Guide wire is added in incoming line and line outlet, only need to be by metal during wiring Line inserts connection jaws and line outlet along guide wire, easy to use, while the guide wire with certain altitude can be hidden Outer part metals line may be exposed to, eliminates potential safety hazard, security reliability is high；（2）In input terminal and outlet terminal Outside add elastic handle, only need to screw and outward winding elastic handle during use, it is more square without instrument, use Just；（3）Fluorescent material is coated in operation handle, is convenient for people to easily operate under dark surrounds, it is easy to use and safe.

Embodiment

The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings.

Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of improved open circuit provided by the utility model Device plastic casing, including plastic casing body 10, plastic casing body 10 include incoming line 101, input terminal 102, manipulator Handle 103, outlet terminal 104 and line outlet, above is the existing structure of breaker, incoming line 101 is corresponding up and down with line outlet, uses In the introducing of enter line side tie-in line and outgoing line side leading-out wire, input terminal 102 and outlet terminal correspond to about 104, for inlet wire The fixation of side tie-in line and outgoing line side leading-out wire, operation handle 3 are used for the combined floodgate and separating brake of breaker.Incoming line 101 and outlet The outside of mouth is provided with integrally formed guide wire 20, and guide wire 20 is to extend outward along the hole wall of incoming line 101 and line outlet The pipeline configuration formed, the insertion for guiding enter line side tie-in line and outgoing line side leading-out wire and breaker connect.Input terminal 102 and the outside of outlet terminal 104 be connected with elastic handle 30, for screwing and outwarding winding input terminal 102 and outlet terminal 104, so as to realize the fixation after the insertion connection to guiding enter line side tie-in line and outgoing line side leading-out wire and breaker.Manipulator Fluorescent material is coated with handle 103, is convenient for people to the operating breaker under dark surrounds.

Further, pipeline configuration is the cylindrical structure that outer end has bell shape, more facilitates enter line side tie-in line Insertion with outgoing line side leading-out wire and breaker connects.

Further, the length of pipeline configuration is 5mm, and the guide wire 20 with certain altitude can be hidden and may be exposed to Outer part metals line, eliminates potential safety hazard, improves the security reliability of breaker.
