Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, but the present invention does not limit to specific embodiment.
Embodiment 1
A kind of control device for earth leakage protective device, including shell 22 and base plate 13, described base plate is fixedly installed in enclosure bottom, and base plate constitutes inner cavity chamber with shell, is used for installing electromagnet, SR etc. and controls parts.
Electromagnet 19 is fixedly installed in base plate side, electromagnet lower end is provided with plug wire head, for connecting the circuit board that electric leakage controls, this circuit board is provided with electric leakage chip and the power supply powered of electromagnet, dynamic iron head 21 is movably installed in inside electromagnet, in the case of electromagnet is energized, dynamic iron head moves to electromagnet direction under magneticaction.
Middle gripper shoe 18 is fixedly installed in the middle part of base plate, and is positioned at inside electromagnet, and dynamic iron head passes in the middle part of middle gripper shoe, and collateral fagging 5 is fixedly installed in base plate opposite side；
Guide 17 and a pair stationary contact bridge 14 are fixed on base plate, and between middle gripper shoe and collateral fagging, a pair stationary contact bridge 14 can be connected on the circuit board that electric leakage controls, it functions as switching device two ends and is connected on the circuit of live wire or zero line, and static contact 12 is fixed on stationary contact bridge upper end；Being provided with lower spring 15 in guide, lower guide pillar 16 is positioned on the lower spring within guide；
Upper guide post 2 is movably installed in shell upper, SR 6 is fixedly installed in upper guide post lower end, SR one is placed on lower guide pillar, this side arranges the snap close 20 raised up, this snap close can agree with dynamic iron head, dynamic iron head blocks snap close, stops SR to move upward, and SR opposite side arranges tactile bridge clip slot pawl 9；Touch that bridge clip slot pawl is internally installed upper spring 7, touch bridge folder 8 and be installed on the upper spring within tactile bridge clip slot pawl；The dynamic bridge 10 that touches is fixedly connected on tactile bridge folder lower end, and movable contact 11 is fixed on dynamic tactile bridge lower end, and is positioned at above static contact.
Touch bridge folder, base plate is insulator, touches bridge folder and preferentially selects made of plastic, and there is perforate at Dong Chuqiao center, and its perforate is inserted after touching bridge folder lower end, by hot riveting technique, the dynamic bridge 10 that touches is fixedly connected on tactile bridge folder lower end.
Dynamic bridge 10, moving contact 11, static contact 12 and the stationary contact bridge 14 of touching is conductor, wherein, moving contact 11 and static contact 12 preferentially select copper product to make, dynamic tactile bridge 10 and stationary contact bridge 14 preferably select silver or aluminum to make, a pair stationary contact bridge bottom is connected with wire respectively, when dynamic tactile bridging is connected on two stationary contact bridges, wire connects, SR lower end can arrange multiple dynamic tactile bridge and stationary contact bridge simultaneously, for controlling conducting and the disconnection of multiple circuit simultaneously, including the switch controlling live wire and zero line simultaneously.
Shell two upper lateral part is provided with card holding trough 23, in order to be installed among insert row or wiring board.
