China's low-voltage electrical apparatus annual value of production reaches hundreds of hundred million, and wherein the output of aftercurrent action protecting electric equipment products accounts for 20% of total production.Aftercurrent action protecting electrical equipment (is called for short residual current protecting electrical equipment; be called leakage current protection electrical equipment again) be a kind of safeguard protection electrical equipment; be widely used in low voltage electric network the personal injury and the electrical equipment damage accident that are used for preventing personal electric shock, electrical fire and cause because of earth fault.The critical piece that influences the aftercurrent action protecting opering characteristic of electric apparatus has residual current transformer, electronic circuit component palette etc.
But the enterprise of existing production aftercurrent action protecting electrical equipment, the checkout equipment of its product component is still more original, and the subject matter of existence is:
(1) present aftercurrent action protecting electrical equipment manufacturer is to adopt the complete verification debugging to the test verification process of parts such as product residual current transformer, electronic circuit component palette.But present detection method is to test by regulating trigger current manually, regulate trigger current by the manual shift resistor, owing to regulate manually and make that the trigger current climbing speed is inconsistent, thereby influence the accuracy of trigger current, cause the consistance of testing product poor.
(2) output of aftercurrent action protecting electrical equipment is very big, and parts such as its residual current transformer, electronic circuit component palette all are to detect one by one, judge testing result by the artificial visually examine, and testing staff's working strength is very big, is easy to generate artificial erroneous judgement.
Therefore; need a kind of residue action current test macro of development; to improve detection efficiency and accuracy of detection; but the design of finishing residue action current test macro needs a kind of anchor clamps that the electronic circuit component palette of aftercurrent action protecting electrical equipment is carried out clamping naturally; finished and detected action; by retrieval, there is not ready-made device can supply usefulness at present.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, can carry out stable holding to finish the residue action current test macro unit clamp of detection to the electronic circuit component palette and provide a kind of, remain stability and the production efficiency that the quality inspection of action current test macro moves thereby improve.
For achieving the above object, the technical solution of the utility model is to include base, described base is provided with lower plate and erects the upright platform that is provided with, the front of described lower plate is erect and is provided with many detector probe, on the described lower plate relatively many detector probe around be provided with the mechanism of shelving of electronic circuit component palette, should include the installing plate that is arranged at its upper end by upright platform, the sidepiece of described installing plate is set with actuating cylinder, described actuating cylinder below is provided with the lifting push rod with the actuating cylinder interlock, the lower end of this lifting push rod is provided with the train wheel bridge relative up and down with lower plate, and the below of this train wheel bridge is set with top-pressure part.
Further being provided with is that described top-pressure part is the elastic caoutchouc spare of many needle-likes, and the elastic caoutchouc spare of its this many needle-likes is distributed on the lower surface of train wheel bridge and is provided with.It is better that this is provided with the clamping effect.
Further being provided with is that the described mechanism of shelving includes 4 columns that distribute around being, and the interior angle of described column is provided with L shaped short slot.
Advantage of the present utility model is: electronic circuit component palette to be detected is shelved on the detector probe of lower plate, electric-conductor electric connection on detector probe and the electronic circuit component palette, cylinder starts then, top-pressure part is pressed on the electronic circuit assembly keeps it to be fixed between train wheel bridge and the lower plate, detect, clamping stability is good, and can realize robotization control by cylinder.
