Background technology
Place at present the detection bogey probe card of isolating switch on the known testing table that adopts for the indices that detects isolating switch whether is up to state standards, be used in conjunction with probe, can realize detecting the purpose of the electric performance of isolating switch.According to the concrete isolating switch of required detection, the position of probe is put in planning and design on probe card, the probe card device that is used for checking the circuit breaker electric characteristic traditionally, and the scope of application is narrower, can be for the isolating switch of models few in number; When using with probe assembling to a piece, because design concept is perfect not, cause the serviceable life of probe very low, very easily damage.Probe is expensive, changes frequently probe, has not only increased cost, also delays test process.Even ceaselessly change probe in order to reach testing goal, owing to its design defect, narrow this shortcoming of the scope of application is not changed yet again.Generally speaking, according to the probe card of traditional design theory design, not only uneconomical material benefit is on the contrary because defective increases cost.
Summary of the invention
The utility model provides the special-purpose needle plate of detection device for electrical characteristics of circuit breaker a kind of simple in structure, easy to make, simple to operate for solving the technical matters that exists in the known technology.
The utility model for the technical scheme that solves the technical matters that exists in the known technology and take is: it include upper and lower probe supporting plate, probe base plate, a plurality of axle sleeve fixture and on described the probe splint upper surface be fixed with fixed head; On the described fixed head with a center square hole that is used for preventing that detected isolating switch from moving at the surface level of probe mounting plate; Described axle sleeve fixture is a long cylinder, and be fixed with near the side end of this cylinder one be used for described axle sleeve fixture is fixed on described on the transverse slat with holes of probe supporting plate lower surface; Have in the time will being detected isolating switch and placing the probe supporting plate at described upper and lower probe supporting plate, respectively pass in and out one to one hole of electrode position with detected isolating switch, the diameter in this hole is passing of can being complementary of described axle sleeve fixture; Also have on the described probe base plate in the time will being detected isolating switch and placing upper probe base plate, respectively pass in and out one to one hole of electrode position with detected isolating switch, the diameter in this hole is passing of can being complementary of the nut on the threaded end of the probe of described electrical specification pick-up unit; Each Kong Shangyong screw of probe supporting plate lower surface is fixed with described axle sleeve fixture on described; Also have a plurality of both can being fixed together each other at described test needle holder plate and probe base plate, be about to simultaneously described electrical specification pick-up unit and be used for connect clamping hole and the fixing screw assembling thereof wherein of axle sleeve lower cover on the probe that detected each line electrode of isolating switch and bench run current output terminal be connected together.
Advantage and the good effect that the utlity model has are: realized relying on a covering device to detect the Multiple Type isolating switch, according to the difference that leans out probe, and then realization detects the isolating switch of different model; The probe axle sleeve is fixed 9 parts probe is played guide effect, and plays the stationary probe effect, keeps the verticality of probe, so that become longer the serviceable life of probe; In addition, the fixedly protective effect of 3 pairs of probe bottoms of probe base plate also so that probe is not easy bending, increases the serviceable life of probe.The utility model is simple in structure, and is easy to make, simple to operate, and integral body provides cost savings.
