A kind of for measuring the tool of surface mounting crystal electrical quantity
The utility model relates to tool field, is a kind of for measuring the tool of surface mounting crystal electrical quantity.
At surface mounting crystal production field, production run need to be spot-check test electrical quantity to the product having encapsulated, and does not have in the market a kind of test fixture to be applicable to this small surface mounting crystal.
Summary of the invention
The purpose of this utility model is to provide a kind of for measuring the tool of surface mounting crystal electrical quantity.
The technical solution of the utility model is: a kind of for measuring the tool of surface mounting crystal electrical quantity, it is characterized in that, on measurement jig base, limited block is housed; On in the hole of test handle, have the axis of guide, have test holddown spring under the axis of guide, the base of test handle is installed on guide holder, and there is testing needle the lower end of test handle.
Owing to having adopted technique scheme, measure surface mounting crystal electrical quantity method simple, saved manpower, improved production efficiency, reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, measurement jig base; 2, limited block; 3, test handle; 4, guide holder; 5, test holddown spring; 6, the axis of guide; 7, testing needle.
Below in conjunction with embodiment, the utility model is further described.
In Fig. 1, limited block 2 is housed on measurement jig base 1; On in the hole of test handle 3, have the axis of guide 6, the axis of guide has test holddown spring 5 for 6 times, and the base of test handle 3 is installed on guide holder 4, and there is testing needle 7 lower end of test handle 3.
Embodiment, first test handle 3 is upwards carried, dextrorotation turn 90 degrees the top of putting to guide holder 4, with tweezers, product test electrode to be tested is put into tool groove upward again, by limited block 2, locate, then test handle 3 is rotated counterclockwise to 90 degree puts to guide holder 4 entrances, acting force due to test holddown spring 5, by guide holder 4, import, just in time testing needle 7 is pressed in to edge on the yellow electrode of product to be tested, to be measured completing taken out product.
