Background technology
in recent years, densification along with the complicated and integrated circuit of circuit board, the probe arrangement pitches of circuit board detection device becomes more and more less, the diameter of probe also must be more and more less, the assembling mode of traditional built-in spring of probe, due to needs further sleeve outside probe, causes the probe arrangement pitches larger than the spring rows column pitch of bottom.Improved method is to make all probes become different gradients to arrange for this reason, and shortcoming is the problem that will certainly produce undercapacity, causes poor flow, thus impact test effect; Also can cause probe springs to descend serviceable life simultaneously, and complex structure, the problem that manufacturing cost is high.
Summary of the invention
the utility model purpose is: the circuit board probe detection device that provide a kind of spread length of probe little, verticality is high, it is little to rock and accuracy of detection is high, and compare routine techniques and there is longer serviceable life and better measuring stability.
the technical solution of the utility model is: a kind of circuit board probe detection device, comprise probe, spring and multilayer location-plate, it is characterized in that described multilayer location-plate comprises the upper location-plate be disposed in order from top to bottom, middle location-plate, lower location-plate, the spring fitting plate, on described, lower location-plate is provided with through hole vertically opposite and that wear for probe, described middle location-plate is provided with the movable span relative with described up/down perforation hole, described probe is provided with one and is positioned at described movable span and can't passes through the limiting section in up/down perforation hole, described spring fitting plate is provided with the spring accommodation hole, described spring is placed in described spring accommodation hole and offsets with described probe.
preferably, the cylindrical boss on probe that is formed in one of limiting section described in the utility model, the diameter of this cylindrical boss is greater than the diameter of the through hole on described upper and lower location-plate.
preferably, the utility model also comprises the outlet board that is placed in spring fitting plate bottom, described spring accommodation hole connects described spring fitting plate, described outlet board is provided with the wire hole that and diameter relative with the spring accommodation hole is less than the spring accommodation hole, described spring upper end is against probe base, lower end is against on outlet board, and described probe bottom is connected with wire and draws from described wire hole.
further, the utility model also comprises the base of being located at the outlet board below, and described base and outlet board are connected to a fixed by least two support columns.
further, the same with routine techniques, the top of described probe is conical tip, and outstanding upper location-plate.
during real work, the same with routine techniques, tips of probes conical tip in the utility model is for the contact of the circuit board with to be detected, and the wire of probe bottom is connected with the detection machine, thereby the check point conducting on circuit board is measured to the detection machine.Through hole on upper and lower location-plate has been guaranteed the verticality of probe, and spring provides probe up and down power, and the limiting section on probe has limited the up and down scope of probe.
the utility model has the advantages that:
the assembly structure that the utility model adopts probe and spring to be separated, spring is contained in independent sheet material, leave the probe space of enough arranging for, the spread length of having guaranteed probe is less, through hole on upper and lower location-plate has been guaranteed the verticality of probe, reduce rocking of probe, improved the accuracy of detection of probe.Compare routine techniques, the utlity model has longer serviceable life and better measuring stability.
