Abstract
The invention relates to a breaker, in particular to a handle of a breaker. The handle of the breaker w comprises a handle body (1) and a lever assembling groove (2) which is formed in the middle of the lower end face of the breaker. The handle of the breaker is characterized in that the lever assembling groove (2) comprises a left limit side wall and a right limit side wall, a left clamping protruding block (4) is arranged on the left limit side wall, a right clamping protruding block (5) is arranged on the right limit side wall, when a lever (3) is arranged in the lever assembling groove (2) in a plug-in mounting mode, a left limit side wall body and a right limit side wall body are respectively connected with the left clamping protruding block (4) and the right clamping protruding block (5) in a clamping mode, and the handle body (1) is connected with the lever (3) in a clamping mode. The handle of the breaker is simple in structure and low in cost. Due to the fact that the handle body is tightly connected with the lever in a clamping mode, assembling is simple and quick, and the breaking speed of the breaker is improved.
Description
Technical field
The present invention relates to the functional unit of circuit breaker especially circuit breaker, is a kind of handle of circuit breaker specifically.
Background technology
Existing circuit breaker, its functional unit is the handle exposed, realize closing a floodgate and sub-switching operation by reciprocating handle, as shown in Figure 1, described handle comprises one handle main body 1, and its end face being positioned at circuit breaker is provided with lever fitting recess 2, is that accessory alive connects between handle main body 1 and lever 3, handle is only rely on the upper cover of circuit breaker to realize spacing to it, and such connected mode has following defect:
1, circuit breaker is in assembling process, because handle main body is connected with lever not tight, easily comes off, affects assembling speed and production efficiency;
2, in debug process, because handle main body is connected with lever not tight, easily makes operator touch light current, make uncomfortable;
3, circuit breaker in use, closely do not have loosening, to make in on/off switch process easily and breaker upper cover friction, affect service behaviour and breaking speed because handle main body is connected with lever.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of handle of circuit breaker, structure is simple, with low cost, and handle main body and lever compact engaging, assembling simple and fast, improves the breaking speed of circuit breaker.
For reaching above object, the technical scheme that the present invention takes is:
A handle for circuit breaker, comprises handle main body 1, is provided with a lever fitting recess 2, it is characterized in that in the middle part of its lower surface being positioned at circuit breaker:
Described lever fitting recess 2 comprises left limit sidewall and right limit sidewall, and left limit sidewall is provided with left clamping projection 4, is provided with right clamping projection 5 at right limit sidewall,
When lever 3 is inserted in this lever fitting recess 2, its left and right wall body split engages with left clamping projection 4, right clamping projection 5, and clamping between handle main body 1 and lever 3 is connected.
On the basis of technique scheme, be provided with a locating convex block 6 in lever fitting recess 2, the end face that lever 3 is positioned at lever fitting recess 2 is provided with the detent 7 with locating convex block 6 adaptation.
On the basis of technique scheme, the width on the limit, left side 8 on the left of detent 7 is less than the width of the right edge 9 on the right side of detent 7,
The width on the spacing between locating convex block 6 and left limit sidewall and limit, left side 8 is adaptive,
The width of the spacing between locating convex block 6 and right limit sidewall and right edge 9 is adaptive.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are Split type structure, and the two is plugged in together.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are formed in one structure.
The handle of circuit breaker of the present invention, structure is simple, with low cost, and handle main body and lever compact engaging, assembling simple and fast, improves the breaking speed of circuit breaker.
The handle of circuit breaker of the present invention, does not need breaker upper cover just can locate, and in debug process, because handle is connected closely with lever, the personnel avoided in experiment touch the sense of discomfort that light current causes.
Accompanying drawing explanation
The present invention has following accompanying drawing:
The structural representation of the handle of the existing circuit breaker of Fig. 1,
The structural representation of the handle of Fig. 2 circuit breaker of the present invention,
The structural representation of handle main body in Fig. 3 Fig. 2,
The structure vertical view of lever in Fig. 4 Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 2,3, 4, the handle of circuit breaker of the present invention, comprising:
Handle main body 1, is provided with a lever fitting recess 2 in the middle part of its lower surface being positioned at circuit breaker,
Described lever fitting recess 2 comprises left limit sidewall and right limit sidewall, and left limit sidewall is provided with left clamping projection 4, is provided with right clamping projection 5 at right limit sidewall,
When lever 3 is inserted in this lever fitting recess 2, its left and right wall body split engages with left clamping projection 4, right clamping projection 5, and clamping between handle main body 1 and lever 3 is connected.
On the basis of technique scheme, be provided with a locating convex block 6 in lever fitting recess 2, the end face that lever 3 is positioned at lever fitting recess 2 is provided with the detent 7 with locating convex block 6 adaptation.
When lever 3 is inserted in this lever fitting recess 2, locating convex block 6 inserts detent 7, and lever 3 can be accurately positioned in lever fitting recess 2.
On the basis of technique scheme, the width on the limit, left side 8 on the left of detent 7 is less than the width of the right edge 9 on the right side of detent 7, the width on the spacing between locating convex block 6 and left limit sidewall and limit, left side 8 is adaptive, and the width of the spacing between locating convex block 6 and right limit sidewall and right edge 9 is adaptive.Different by the width of both sides, achieve fool-proof design, lever 3 cannot oppositely insert in lever fitting recess 2 by assembly crewman, improve fail safe, and make assembling process simpler, accurately, high efficiency.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are Split type structure, and the two is plugged in together.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are formed in one structure.Such as: integrated injection molding.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
