Abstract
The utility model discloses an electric leakage breaker, comprising a housing, the upper and lower both ends of casing are provided with the wiring bolt, the casing constitute by well frame and the end cover concatenation that is arranged in the frame left and right sides respectively, it is equipped with the boss to correspond wiring bolt position on the preceding terminal surface of casing, the boss by the intermediate mass and the limit piece that lies in the intermediate mass left and right sides respectively constitute, intermediate mass integrated into one piece on the preceding terminal surface of well frame, limit piece integrated into one piece on the preceding terminal surface of end cover, the cooperation of pegging graft of intermediate mass and limit lump formation, the through -hole that supplies the wiring bolt to pass is offered to intermediate mass and the junction of limit piece, intermediate mass and limit piece outward still the interference cover protective sheath is equipped with, and the preceding terminal surface of protective sheath seal and constitute right coveing of through -hole. Through adopting the structure mentioned above, the utility model provides a connect more firm, the safer electric leakage breaker of use.
Description
Technical field
This utility model is related to a kind of RCCB.
Background technology
RCCB mainly includes housing, and the upper and lower ends of described housing are provided with connection bolt, connection bolt from
The front end face insertion of housing, and be tightened on housing, simultaneously described housing is located at a middle frame left side typically by middle frame and respectively
The end cap of right both sides is spliced to form, and connection bolt is usually located between middle frame and end cap, but because described housing is plastics system
One-tenth, and usual thinner thickness, therefore connection bolt if firmly excessive during wiring turn, be then easily caused housing and open
Split, additionally, after connection bolt screws, the head of connection bolt still can be exposed, so not only easy and other wires or thing
Body is swiped, and external dust also the easily through hole by being matched with connection bolt is entered in chopper, thus affecting
The safe handling of chopper.
Content of the invention
For the deficiencies in the prior art, it is more firm, disconnected using safer electric leakage that this utility model provides a kind of connection
Road device.
For achieving the above object, this utility model provides a kind of RCCB, includes housing, described housing upper
Lower two ends are provided with connection bolt, and described housing is located at the end cap of the middle frame left and right sides and be spliced to form by middle frame and respectively, institute
The position stating on the front end face of housing corresponding connection bolt is provided with boss, and described boss is located at by intermediate mass and respectively
Between the side block of the block left and right sides constitute, intermediate mass is integrally formed on the front end face of middle frame, and side block is integrally formed before end cap
On end face, intermediate mass and side block form grafting cooperation, and intermediate mass is offered for leading to that connection bolt passes through with the joint of side block
Hole, going back interference outside described intermediate mass and side block has protective case, and the front end face closure of protective case constituting to described logical
The covering in hole.
The beneficial effects of the utility model are：Using said structure, due to wiring spiral shell corresponding on the front end face of described housing
The position of bolt is provided with boss, therefore passes through to arrange boss, can greatly reinforce the intensity of housing, and be prevented effectively from connection bolt
Housing is led to ftracture because exerting oneself excessive during wiring turn.Meanwhile, because described boss is by intermediate mass and difference position
Side block in the intermediate mass left and right sides is constituted, and intermediate mass is integrally formed on the front end face of middle frame, and side block is integrally formed in end cap
Front end face on, intermediate mass and side block form grafting cooperation, therefore pass through the grafting cooperation of intermediate mass and side block, can make middle frame with
It is more firm that end cap connects.Additionally, going back interference outside described intermediate mass and side block have protective case, and the front end of protective case
Face closure simultaneously constitutes covering to described through hole, therefore passes through to arrange protective case, not only can be prevented effectively from the head of connection bolt
And through hole exposes, and can also make intermediate mass and side block combination more firm, thus in improving further frame is with end cap even
The fastness connecing.
This utility model can be further arranged to described intermediate mass and be provided with inserting column, described side block is correspondingly provided with
Described inserting column constitutes the jack of grafting cooperation；Or described side block is provided with inserting column, described intermediate mass is correspondingly provided with
Described inserting column constitutes the jack of grafting cooperation.
Brief description
Fig. 1 is structure chart of the present utility model；
Fig. 2 is structure decomposition figure of the present utility model；
Fig. 3 is the one of which profile of boss in this utility model；
Fig. 4 is another kind of profile of boss in this utility model.
Specific embodiment
Give a kind of RCCB as Figure 1-4, include housing, the upper and lower ends of described housing are provided with and connect
Line bolt 1, described housing is located at the end cap 3 of middle frame 2 left and right sides and be spliced to form by middle frame 2 and respectively, before described housing
On end face, the position of corresponding connection bolt 1 is provided with boss, and described boss is located at intermediate mass 4 left side by intermediate mass 4 and respectively
The side block 5 of right both sides is constituted, and intermediate mass 4 is integrally formed on the front end face of middle frame 2, and side block 5 is integrally formed the front end in end cap 3
On face, intermediate mass 4 and side block 5 form grafting cooperation, and the joint of intermediate mass 4 and side block 5 offers and passes through for connection bolt 1
Through hole 6, go back interference has protective case 7 to described intermediate mass 4 outward with side block 5, and the front end face 71 of protective case 7 is closed and constituted
Covering to described through hole 6.By adopting said structure, it is more firm, using safer that this utility model provides a kind of connection
RCCB.
The intermediate mass 4 that the grafting cooperation of described intermediate mass 4 and side block 5 can be described is provided with inserting column 8, described side block
It is correspondingly provided with the jack 9 constituting grafting cooperation with described inserting column 8 on 5；Or described side block 5 is provided with inserting column 8, described in
Between the jack 9 being constituted grafting cooperation with described inserting column 8 is correspondingly provided with block 4.
