Earth leakage protective device 2 plays the role of controllable silicon body 1 earth leakage protective, ensure that the stability of silicon-controlled work, while
It is provided with circular platform type double wedge 6 on pin 3, when welding, increases the contact area between 3 scolding tin of pin, rosin joint can be effectively avoided,
Stabilized structure is not easy loosely, and performance is stablized.
Top inside the controllable silicon body 1 is provided with damping device 7, the damping device 7 include upper cover plate 71, under
Cover board 72 and damping spring 73, one end of the damping spring 73 is connect with upper cover plate 71, the other end and lower cover plate 72 connect.
The damping device 7 is conducive to be squeezed or whens other physical shocks absorbs cushion effect silicon-controlled, and further protecting can
The internal component for controlling silicon, improves its stability.
It is additionally provided with protection cap 74 between the upper cover plate 71, lower cover plate 72, which is arranged in damping spring 73
Two sides damping spring 73 is carried out enclosing protection, and be also beneficial to prevent spring from occurring falling into silicon-controlled inside after falling off
Cause security risk.
Heat release hole 8 is offered on the controllable silicon body 1, is provided with waterproof ventilated membrane 9 in the heat release hole 8, is designed in this way
The heat discharge generated when both by silicon-controlled work, also prevents moisture and enters inside controllable silicon body 1.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the utility model aim technical solution belong to the protection scope of the utility model it
It is interior.
