The resistance board reliability detector has the advantages of being capable of screening resistance boards and guaranteeing the fact that the resistance boards of sensors mounted on vehicles meet reliability quality detection requirements, is mainly used for detecting the reliability of the resistance boards in resistance board production, and guarantees the fact that burnout of resistance wires can be avoided when electric current is enlarged and the vehicle is mounted.
Description
Technical field
The invention belongs to electric detective technology field.Be specifically related to a kind of instrument that detects resistance board reliability of producing for resistance board.
Background technology
In the production of automobile sensor, need the resistance board of all size, the enameled wire being wound around on resistance board will fall enamel-cover layer brushing could conducting.But manual brushing exists weight to be difficult for grasping, the problems such as the impaired difficult discovery of resistive conductor.While often having arrived automobile loading, strengthen electric current and cause resistive conductor to blow, cause sensor failure.
summary of the invention
Object of the present invention is exactly to provide a kind of continuous current detector that can guarantee entrucking sensor current reliability for above-mentioned weak point.This detector can screen resistance board under the condition such as electric current, time on request, rejects underproof resistance board.
Technical solution of the present invention is: a kind of resistance board reliability detector, is characterized in that: be made up of accurate constant-current source, time meter electrical equipment and detection fixture; Described detection fixture comprises clamping fixture seat, geometrical clamp is concrete and live splint concrete, spring, and clamping fixture seat is the pedestal that there is strip boss in central authorities, and geometrical clamp is specifically fixedly connected on the boss of this clamping fixture seat, and live splint is specifically screwed on the boss of clamping fixture seat; Geometrical clamp is concrete and live splint is specifically other is provided with two columns, on the column that spring is fixed therein; Between accurate constant-current source, time meter electrical equipment and detection fixture, electricity in succession.
Accurate constant-current source described in technical solution of the present invention comprises first, second accurate constant-current source; Totally four groups, the concrete and spring of the concrete and live splint of geometrical clamp, front two groups of clamping fixture seats and spring are series connection, rear two groups of clamping fixture seat springs are for connecting.
The present invention is owing to adopting by accurate constant-current source, time meter electrical equipment and detecting the resistance board reliability detector that fixture forms, and wherein, holddown spring is equipped with in the both sides of detecting fixture, and can guarantee to detect time, contact be good.Resistance board is directly pressed into detection fixture, and resistance wire is pressed in spring, and the electric current and the detection time that on time meter electrical equipment and accurate constant-current source, set requirement can be detected.As disconnected in institute's measuring resistance plate resistance silk thread or in seeking time, current value, blown by electric current wanting, so accurate constant-current source shows and is output as 0. if resistance board is wanting to show normal current in seeking time, current value, and resistance board is qualified.The present invention is mainly used in reliability after the resistance board brushing of all size to detect.This detection fixture amount detection is added and subtracted arbitrarily (an accurate constant-current source detects two resistance boards) after can being equipped with as required accurate constant-current source.Detecting the width of fixture can adjust arbitrarily, can solve the resistance board test problems of various models, and this detector current value can adjust arbitrarily on accurate constant-current source, and can count on electrical equipment and can adjust arbitrarily detection time in the time.The present invention has under the condition such as electric current, time requiring resistance board is screened, and rejects underproof resistance board, can guarantee that the resistance board of entrucking sensor meets the feature that reliability quality testing requires.The present invention is mainly used in detecting in resistance board production the reliability of resistance board, strengthens electric current and can not cause resistive conductor to blow while guaranteeing automobile loading.
