Technical field
The utility model relates to the auxiliary test unit in a kind of Electronic Components Manufacturing process, particularly a kind of inductor E-type magnetic core inductance and size separation device.
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.
4. inductance measurement and size separation separate, need many more manipulations, labour intensity is large, and cost of labor is high.
Summary of the invention
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provide a kind of pressing force even, test result accurately, reliably, and can carry out inductor E-type magnetic core inductance and the size separation device of sorting simultaneously to the foreign minister of E-type magnetic core, interior length and core length size.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of inductor E-type magnetic core inductance and size separation device, comprise LCR electric inductance measuring-testing instrument and coaxial skeleton, top board and the lower platen arranged, skeleton is fixed on directly over lower platen by insulating support, top board is fixed on directly over skeleton, and the height of top board and lower platen all can be elevated; The bottom of top board is provided with downward opening first indent, and the top of lower platen is provided with the second opening up indent; First indent is identical with the bottom shape of E-type magnetic core with the second indent, and the length of the first indent and the second indent is equal to the maximal value of E-type magnetic core foreign minister; The center of skeleton is provided with central through hole, and the shape of this central through hole is identical with the newel shape of E-type magnetic core, and the length of central through hole equals the maximal value of E-type magnetic core core length; The periphery of skeleton is wound with coil, and the two ends of coil are connected with LCR electric inductance measuring-testing instrument; The foreign minister of skeleton equals the long minimum value of E-type magnetic in-core.
Pressure transducer is provided with in described first indent.
Pressure transducer is provided with in described second indent.
Elastic rubber layer is provided with in described first indent and the second indent.
After the utility model adopts said structure, there is following beneficial effect:
1. top board is that face contacts with lower platen and the bottom of E-type magnetic core, assembles similar to actual electrical sensor.In addition, the setting of above-mentioned pressure transducer, can control the bottom pressing force of two E-type magnetic cores, and pressing force is even, thus test result accurately, reliably.
2. above-mentioned first indent, the first indent can carry out sorting to E-type magnetic core foreign minister, and skeleton can carry out sorting to E-type magnetic in-core length and E-type magnetic core core length.Also, namely, while inductance measurement, sorting can be carried out to the foreign minister of E-type magnetic core, interior length and core length size.Thus labour intensity is little, save manpower.

Embodiment
Below in conjunction with accompanying drawing and concrete better embodiment, the utility model is described in further detail.
As shown in Figure 2, E-type magnetic core 4 has E-type magnetic core core length 41, E-type magnetic in-core long 42 and E-type magnetic core foreign minister 43, and these sizes, concerning the assembling of inductor and inductance, are significant dimensions, need strict management and control.
As shown in Figure 1, a kind of inductor E-type magnetic core inductance and size separation device, comprise LCR electric inductance measuring-testing instrument 13 and coaxial skeleton 1, top board 2 and the lower platen 3 arranged.
Skeleton is fixed on directly over lower platen by insulating support, and top board is fixed on directly over skeleton, and the height of top board and lower platen all can be elevated.
The bottom of top board is provided with downward opening first indent, and the top of lower platen is provided with the second opening up indent; First indent is identical with the bottom shape of E-type magnetic core with the second indent, and the length of the first indent and the second indent is equal to the maximal value of E-type magnetic core foreign minister.When E-type magnetic core foreign minister's super large, the first indent or the second indent can not be put into, namely realize the sorting to E-type magnetic core foreign minister size.
The center of skeleton is provided with central through hole, and the shape of this central through hole is identical with the newel shape of E-type magnetic core, and the length of central through hole equals the maximal value of E-type magnetic core core length.When E-type magnetic core core length super large, can not enter in central through hole, thus realize the sorting to E-type magnetic core core length size.
