Description
Technical field
The invention belongs to field of automobile, more particularly, to a kind of shrapnel contact break-make and disconnection instantaneous pressure test
Device, above-mentioned shell fragment is widely used on automobile ignition switch and the socket of automobile combined switch.
Background technology
Vehicle switch is the switch controlling automotive control circuit, plays act foot in terms of vehicle safety, comfortableness
It may be said that not having these switches, automobile is difficult to move even one step for the effect of weight.If automobile is before normally travel, ignition switch need to be passed through
To start electromotor；Automobile needs to transmit signal by headlamp switch in the process of moving.However, existing spring-piece type switch exists
Service life has length to have short defect, and on combined socket and switch under normality, the movable contact of shell fragment is in the conduction state with stationary contact, existing
Method of testing need to be detected one by one, efficiency is very low using circuit tester, in addition use when find such switch use
Contact pressure between life-span and contact has substantial connection, if contact pressure is excessive, switchs serious wear, impact uses the longevity
Life, if contact pressure is too small, is also easy to produce the defect of loose contact.Therefore, how quickly to identify whether tested contact is located
Whether the contact pressure under conducting state, and its conducting state meets design requirement, it has also become those skilled in the art are urgently
Problem to be solved.
Content of the invention
In consideration of it, it is an object of the invention to provide a kind of shrapnel contact break-make and disconnection instantaneous pressure test device, solving
Existing pressure test device detection efficiency is low, the not high problem of precision, largely avoided service life product not up to standard and flows into
Next procedure.
