Power spring 2 and conductive metal ring 3 limit by self and pedestal 1 internal diameter size in pedestal 1 separately, and annulus wall does not contact with the conducting metal post 4 at center in it;

Each conducts electricity the Kong Weiyong glue sealing that exit passes.

Described miniature shock sensors is by described vertical direction state, when non-inductive vibrations, conductive metal ring 3 is withstood by spring, do not contact with the maximum step 4c face of conducting metal post 4, pogo pin 2a and conducting metal post 4 are drawn between the conducting end and are disconnected, shockproof signal output;

When the induction vibrations, own weight because of vibrations and conductive metal ring 3, the elastic oscillation up and down of power spring 2 bodies, make instantaneous the contacting of maximum step 4c face of conductive metal ring 3 and conducting metal post 4, pogo pin 2a and conducting metal post 4 are drawn just to produce between the conducting end and are conducted, externally under the circuit function, sensor pin is exported vibration signal; Shockproof again induction, power spring 2 body elasticities reset, and the conductive metal ring 3 and the maximum step 4c face of conducting metal post 4 are left again, make the external circuit open circuit, the shockproof signal output of sensor pin.

The sensing sensitivity of the utility model shock sensor can be by changing conductive metal ring 3 and conducting metal post 4 maximum step 4c faces vertically opposite distance and/or select for use the spring of different elastic propertys and size to regulate.

The utility model shock sensor, its low cost of manufacture, product is Miniaturized, and sensing sensitivity can require to make according to difference easily.
