Description
Technical field
The invention belongs to electric detective technology field.It is specifically related to a kind of instrument detecting resistance board reliability in resistance board produces.
Background technology
Needing the resistance board of all size in the production of automobile sensor, the enamel-covered wire that resistance board is wound around to fall enamel-cover layer brushing could turn on.But manual brushing exists weight to be difficult to grasp, and resistive conductor is impaired is difficult to the problems such as discovery.When often having arrived automobile loading, high current causes resistive conductor to blow, and causes sensor failure.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned weak point and provides a kind of constant current detector that can guarantee that entrucking sensor current reliability.Resistance board can be screened under the conditions of electric current on request, time etc. by this detector, rejects underproof resistance board.
The technical solution of the present invention is: a kind of resistance board reliability detector, it is characterised in that: it is made up of accurate constant-current source, time meter electrical equipment and detection fixture；Described detection fixture includes that clamping fixture seat, fixation clamp be concrete and floating holder body, spring, and clamping fixture seat is the pedestal that there are strip boss in central authorities, and fixation clamp is specifically fixedly connected on the boss of this clamping fixture seat, and floating holder body is screwed on the boss of clamping fixture seat；Fixation clamp specifically and is provided with two columns, on the column that spring is fixed therein by floating holder body；Between accurate constant-current source, time meter electrical equipment and detection fixture, electricity is in succession.
Accurate constant-current source described in the technical solution of the present invention includes first, second accurate constant-current source；Fixation clamp is concrete and floating holder body and totally four groups of spring, front two groups of clamping fixture seats and spring are series connection, and rear two groups of clamping fixture seat springs are series connection.
Due to the fact that and use the resistance board reliability detector being made up of accurate constant-current source, time meter electrical equipment and detection fixture, wherein, the both sides of detection fixture are equipped with holddown spring, it is ensured that during detection, contact is good.Resistance board is pressed directly into detection fixture, and in resistance wire press-in spring, the electric current and the detection time that set requirement on time meter electrical equipment and accurate constant-current source can be detected.As institute's measuring resistance plate resistance silk thread is disconnected or is blown by electric current in wanting seeking time, current value, then accurate constant-current source shows that being output as 0. such as resistance board shows normal current in wanting seeking time, current value, and resistance board is qualified.Present invention is mainly used for reliability detection after the resistance board brushing to all size.This detection fixture amount detection arbitrarily adds and subtracts (accurate constant-current source two resistance boards of detection) after can being equipped with accurate constant-current source as required.The width of detection fixture can arbitrarily adjust, it is possible to resolve the resistance board test problems of various models, and this detector current value arbitrarily can adjust on accurate constant-current source, and the detection time can arbitrarily can adjust on time meter electrical equipment.The present invention has and screens resistance board under the conditions of the electric current required, time etc., rejects underproof resistance board, can guarantee that the resistance board of entrucking sensor meets the feature that reliability quality testing requires.Present invention is mainly used for detecting the reliability of resistance board during resistance board produces, it is ensured that during automobile loading, high current does not results in resistive conductor and blows.

Detailed description of the invention
As shown in Figures 1 to 5.The present invention is made up of the time relay 1, detection fixture, first Precision Current Component the 3, second Precision Current Component 4.The model of the time relay is DH48S-2Z, and the model of Precision Current Component is PSH-3160.Detection fixture includes that clamping fixture seat 2, fixation clamp be concrete and spring 5, floating holder body 6, column 7.Wherein, clamping fixture seat 2 is bakelite rectangle (there are strip boss in central authorities) pedestal.Fixation clamp is specially the half of holder part, is fixedly connected on the boss of clamping fixture seat 2.Floating holder body is second half of holder part, is screwed on the boss of clamping fixture seat 2.Fixation clamp specifically with between floating holder body relative to face be provided with the draw-in groove 8 of cooperation, it is ensured that fixed resistance plate 9 and draw-in groove 8 width adjustable.Fixation clamp is concrete and floating holder body 6 is other is provided with two columns 7, and one of them column is fixed with spring 5.Accurate constant-current source includes the first accurate constant-current source 3 and the second accurate constant-current source 4, totally four groups of clamping fixture seat 2 and spring 5, the most front two groups of clamping fixture seats 2 and spring 5 are series connection, rear two groups of clamping fixture seats 2 and spring 5 are series connection, one accurate constant-current source two resistance board of detection, two accurate constant-current sources can detect four resistance boards simultaneously.First Precision Current Component the 3, second Precision Current Component 4, time meter electrical equipment 1 and fixation clamp is concrete and between floating holder body 6 electricity is in succession.
Draw-in groove 8 is other is provided with spring 5, it is ensured that during detection, contact is good.Resistance board 9 being pressed directly into detection clamping fixture seat 2, compresses in resistance wire press-in spring 5, the electric current and the detection time that set requirement on time meter electrical equipment 1 and first, second accurate constant-current source 3,4 can be detected.As resistance board 9 line is disconnected or is blown by electric current in wanting seeking time, current value, then the first accurate constant-current source 3 and/or the second accurate constant-current source 4 display are output as 0.As resistance board 9 shows that in wanting seeking time, current value normal current, resistance board 9 are qualified.Clamping fixture seat 2 quantity is arbitrarily added and subtracted after can being equipped with accurate constant-current source as required.Detection fixture draw-in groove 8 width can arbitrarily adjust, it is possible to resolve the resistance board test problems of various models, adjust structure with reference to Fig. 7.This detector current value arbitrarily can adjust on accurate constant-current source, and the detection time can arbitrarily can adjust on time meter electrical equipment.
