Description
Technical field
The present invention relates to the auxiliary test unit in a kind of Electronic Components Manufacturing process, particularly a kind of E-type magnetic core inductance measurement frock.
Background technology
Inductor E-type magnetic core, during use, needs pairing to use.Due to sintering and grinding reason, part E-type magnetic core inductance may be caused not meet the inductance requirement of defined.Therefore, dispatching from the factory or before inductor assembling production, needing to criticize shipment or use the inductance of batch E-type magnetic core to test or total sorting, undesirable for inductance magnetic core is sorted out.
During existing E-type magnetic core inductance measurement, testing tool is very simple, as the coil of manual coiling some circle, this coil is directly sleeved on the newel of one of them E-type magnetic core, the two ends of coil are connected with LCR electric inductance measuring-testing instrument, then, another E-type magnetic core and the E-type magnetic core being set with coil are matched, hand exerts oneself the bottom of pressing two E-type magnetic cores, finally read reading on LCR electric inductance measuring-testing instrument and judge.
Above-mentioned testing tool and method of testing, also exist following deficiency:
1. hand exert oneself the bottom of pressing two E-type magnetic cores time, everyone pressing power is different, causes the closeness of contact of two E-type magnetic core mating surfaces different, thus makes test result error comparatively large, and the accuracy of test result and fiduciary level are not high.
2. hand exert oneself the bottom of pressing two E-type magnetic cores time, finger is point cantact with the bottom of E-type magnetic core, due to E-type magnetic core grind time, easily there is trickle out-of-flatness or gap in its mating surface, therefore during pressing, middle or two bottom sides bottom finger presses, the inductance value of testing is widely different, the out-of-flatness of easy elimination mating surface or gap error, to assemble phase difference very large with actual electrical sensor.Usually there will be, dispatch from the factory or use front inductance detection qualified, but the underproof phenomenon of assembling inductance of reaching the standard grade occurs.
3. coil directly contacts with E-type magnetic core, and because E-type magnetic core corner is relatively more sharp-pointed, be easy to puncture the outer field insulated hull of coil, cause test result inaccurate, the serviceable life of coil is short.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of pressing force even, and test result is accurate, reliable, E-type magnetic core inductance measurement frock simple to operate.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of E-type magnetic core inductance measurement frock, comprise base, skeleton, upper spring bearer plate, lower spring pressing plate and LCR electric inductance measuring-testing instrument, skeleton, upper spring bearer plate and lower spring pressing plate are coaxially arranged; Lower spring bearer plate is fixed on base, and skeleton is fixed on directly over lower spring pressing plate by insulating support, and upper spring bearer plate is fixed on directly over skeleton; Be connected by lifting guide pillar between upper spring bearer plate and lower spring pressing plate; The bottom of described lower spring pressing plate is provided with at least two spacing projections, for fixing bottom E-type magnetic core to be measured; The center of described skeleton is provided with the central through hole that E-type magnetic core center pillar to be measured can be made to pass through; The periphery of skeleton is wound with coil, and the two ends of coil are connected with LCR electric inductance measuring-testing instrument; Described base is provided with elevating control button.
Each described spacing projection is all slidably connected with lower spring pressing plate.
The length elongation of described lifting guide pillar driven by the motor be arranged in upper spring bearer plate or lower spring pressing plate.
The side of described upper spring bearer plate and the contiguous skeleton of lower spring pressing plate is provided with elastic rubber layer.
After the present invention adopts said structure, have following due to effect:
1. going up spring bearer plate with lower spring pressing plate and the bottom of E-type magnetic core is that face contacts, and assembles similar to actual electrical sensor.In addition, by the control to spring restoring force in upper spring bearer plate and lower spring pressing plate, thus can control the bottom pressing force of two E-type magnetic cores, and pressing force is even, thus test result accurately, reliably.
2. during test, an E-type magnetic core is upside down in skeleton top, makes the newel of E-type magnetic core stretch in the central through hole of skeleton, it is interior and fixing that another E-type magnetic core is just being placed on spacing projection.Then, press the elevating control button on base, lifting guide pillar is shortened, upper spring bearer plate and lower spring pressing plate will press bottom E-type magnetic core, can carry out inductance measurement.After having tested, also only need again press elevating control button, lifting guide pillar is extended, and upper spring bearer plate and lower spring pressing plate will leave bottom E-type magnetic core, will be convenient to the taking-up of E-type magnetic core, thus simple to operate.
