Above-mentioned a kind of separate type detector for electric fire protection; Wherein, Be provided with gathering sill in the said housing, said controller inserts in the said housing through gathering sill, and said housing is provided with capping; Said capping and said housing removably connect, and said capping is fixed on said controller in the said housing.
Above-mentioned a kind of separate type detector for electric fire protection, wherein, the face of said capping and shell is provided with grab, and said housing is provided with the draw-in groove that matches with said grab, and during connection, said grab is stuck in the draw-in groove.
Above-mentioned a kind of separate type detector for electric fire protection, wherein, said controller comprises two pcb boards, two dismountable linking into an integrated entity of said pcb board for dividing body structure.
Above-mentioned a kind of separate type detector for electric fire protection, wherein, the mode that two said pcb boards are pegged graft through contact pin and socket links into an integrated entity.
The utility model can be realized following beneficial effect:
1, because said separate type detector for electric fire protection comprises housing, leakage current sensor, controller, said leakage current sensor is fixed in the said housing; Said controller is dismountable to be installed in the said housing, in case controller breaks down, only needs the controller replacing is got final product; And controller adopts modular design; Identical controller can be installed in the housing of different size, and so not only versatility is good, and can significantly reduce production costs; And it is easy to maintenance, simple in structure.
2, owing to be provided with gathering sill in the said housing; Said controller inserts in the said housing through gathering sill; Said housing is provided with capping, and said capping and said housing removably connect, and can make controller easy to loading and unloading; And accomplished controller fixing in housing, made the utility model Stability Analysis of Structures.
3, because the cooperation through the grab draw-in groove of capping and housing realizes being connected, when the controller damage need replacing, need withstand trip and shift out capping and get final product, operate more convenient.
4, because said controller is the branch body structure, in the use, but convenient for maintaining.
The mode of 5, pegging graft through contact pin and socket owing to two said pcb boards links into an integrated entity; Abutment between contact pin and the socket has certain length; The spacing of two pcb boards can be in engagement range free adjustment, to adapt to the spacing between the housing, easier for installation.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure; In order to solve the problems of the technologies described above, a kind of separate type detector for electric fire protection of the utility model comprises housing 10, leakage current sensor 1, controller 2; Said leakage current sensor 2 is fixedly mounted in the housing 10 of injection moulding; Form a cavity 3 between leakage current sensor 1 and the inner walls, controller 2 is dismountable to be installed in this cavity 3 of housing 10, and be arranged on said leakage current sensor 1 above; Said leakage current sensor 1 links to each other with the connecting line 12 of said controller 2 through the form of patching, in case the detector controller 2 of this structure breaks down, only needs controller 2 replacings are got final product; And controller adopts modular design; Identical controller can be installed in the housing of different size, and so not only versatility is good, and can significantly reduce production costs; And it is easy to maintenance, simple in structure.
The mode that controller 2 is installed in the housing is unrestricted, for easy for installation, through the mode of inserting controller 2 is installed in the housing 10 in the present embodiment; Be provided with gathering sill 4 in the said housing 10, said controller 2 inserts in the said housing 10 through gathering sill 4, and said housing 10 is provided with capping 8; Said capping 8 removably connects with said housing 10, and said capping 8 is fixed on said controller 2 in the said housing 10, and the position that capping 8 is provided with is unrestricted; Can on housing 10, also can pass through the installation of the cooperation realization capping 8 of grab draw-in groove in the present embodiment in the side; The face that capping 8 cooperates with housing 10 is provided with grab 9, and said housing 10 is provided with the draw-in groove 5 that matches with said grab 9, during connection; Said grab 9 is stuck in the draw-in groove 5, thereby capping 8 is installed on the housing 10.
