Background technology

Existing a kind of electronics and circuit board detection device comprise the insulation detecting plate that is provided with some jacks and place the some probe assemblies and the lead of jack respectively, described detecting plate is connected to form up and down by a dials, a spring holder and a base, each probe assembly is made of a probe and a spring, they are contained in the through hole of dials and spring holder respectively and offset up and down and are connected, and it is interior and weld together with the afterbody of spring that an end of lead is contained in the through hole of base.For probe is located in dials, all probes adopt the little probe of middle part external diameter big both sides external diameter, are stuck in the corresponding dials through hole.Above-mentioned this pick-up unit since the external diameter of probe be not easy to do little, so test density is limited; Spring must with wire bonds together, its external diameter also is unfit to do little, test density is limited, the welding difficulty is bigger, cost height, also easy-maintaining not.

Summary of the invention

The purpose of this utility model is the problem that exists at above-mentioned a kind of electronics and circuit board detection device, and a kind of test density, electronics and circuit board detection device easy to maintenance of increasing is provided.

The purpose of this utility model is achieved in that the utility model comprises insulation detecting plate and some probe assembly and the leads that places jack that is provided with some jacks, also comprise multi-tap, one end of lead is connected with the binding post on the multi-tap, described detecting plate is by the last dials that is provided with some through holes, spring holder, following dials and base up and down successively stack combinations form, the corresponding up and down back of their through hole constitutes jack, the described dials of going up, following dials comprises two or multilayer board respectively, in each dials, also be provided with the insulation elastic force cloth that is used to block probe, it is pressed on up and down between the two-ply, each probe assembly comprises first probe, the spring and second probe, they lay respectively at dials, spring holder, also corresponding up and down successively contact in the through hole of following dials, the other end of described lead be fixed in the through hole of base and with the corresponding contact of tail end of second probe, described second probe all adopts staight needle, in described some probe assemblies, first probe that is used for detecting the probe assembly of IC pad adopts and the consistent staight needle of the corresponding second probe thickness.

Technique effect of the present utility model is:

1, the utility model medi-spring and lead need not weld, and be easy for installation, reduces defective products, can reduce cost.

2, raising along with the usage ratio of the raising of circuit board precision and surface mount elements, the counting of IC pad that needs to detect also correspondingly improved, the ratio of IC pad in total check point that causes needing in the circuit board of middle and high end to detect surpasses 80%, adopt staight needle (needle body external diameter unanimity of same probe) owing to be used for detecting first probe of the probe assembly of IC pad in the utility model, can reduce the probe cost greatly, and be convenient to the making of meticulous probe, thereby can use the littler probe of external diameter, spring does not need and the littler spring of wire bonds external diameter yet easy to use simultaneously, therefore test density can be increased, and absolute vertical checkout can be accomplished.

3, probe and spring are consumable accessory, and the utility model repair and replacement are convenient.

4, being used for detecting probe assembly first probe of IC pad in the utility model can shared corresponding second probe, can reduce the specification of probe.
