Abstract

The utility model relates to a wiring harness fault detector having a function for producing voices. The utility model is characterized in that the detector is provided with a probe pen; the input wire is connected with one group of indicators and simultaneously connected with one group of AND gates and a logic circuit; one group of voice circuits are controlled by the output of the logic circuit and the AND gates, the output of the voice circuits is sent to a loudspeaker through an audio potentiometer and an audio power amplifier, and the loudspeaker sends out sound which is consistent with detected results. For wiring harnesses of which the single end is a connector, the detector is convenient and quick in use.

Description

Voice wire harness fault locator

Affiliated technical field

Whether qualified the utility model relates to a kind of instrument product, be a kind of by sending voice checks wire harness instrument.

Background technology

Wire harness manufacturer or use producer to wire harness qualified will testing whether, in the check wire harness lead whether exist open circuit, short circuit and wrong wire distribution fault.For the harness lead two ends all is the wire harness of connector, wire harness detector on the market can be tested to wire harness easily and fast, but for single-ended be that (a branch of lead one end all links to each other with connector for the wire harness of connector, the other end does not link to each other with connector), wire harness detector on the market must at first manually will couple together with wire harness detector corresponding terminal respectively less than lead one end that links to each other with connector, just can finish detection, so promptly time-consuming, easily make mistakes again, and, connect pretty troublesome to an end tape light and this situation of button.According to understanding on the market and the result for retrieval on the internet, the present instrument of also not testing at the single-ended wire harness that connector arranged, these voice wire harness fault locator is intended to the convenient wire harness of checking single-ended band connector fast and accurately.This instrument is touched lead one end that does not connect connector by a probe pen by root, and instrument sends the conducting situation of this lead of voice informing at once, and all leads touchings finish, and this wire harness fault detect is also finished.

Summary of the invention

The utility model is compared with existing wire harness detector, mainly contains four big advantages: 1. connect by the method for touching with probe pen but not patching, speed is fast; 2. the touching lead is regardless of order, need not consider which terminal which root lead connects; 3. carry out fixedly connected place to being difficult for, as have the place of pilot lamp, pushbutton switch, touching seems and is easy to; 4. testing result is expressed with voice at once, need not divert sb.'s attention, just can on top of whole wire harness testing result, detect more reliable.

The utility model reaches the technical scheme that this four big advantage takes: probe pen has 5V voltage, when probe pen contacts certain root lead: 1. under the normal condition, 5V voltage enters in the corresponding incoming line of instrument by lead other end connector and supporting frock, the pilot lamp of corresponding this root lead is bright, the corresponding sound circuit of 5V voltage triggered on this lead of while, through the audio frequency potentiometer, audio power amplifies and promotes loudspeaker and send corresponding sound, and the operator hears that the content of this sound is consistent with the meaning of this lead; 2. this wire break, 5V voltage just can not enter instrument so, and pilot lamp does not work, and sound circuit is triggered, and does not also have sound to send; 3. this lead stagger the time in the connector termination (also being wrong wire distribution), 5V voltage enters instrument by another lead, the another one pilot lamp is bright, the another one sound circuit is triggered simultaneously, send another sound, this sound-content and the lead meaning that is touched are inconsistent, and the operator just knows that this root lead received on the connector terminals that root lead consistent with sound-content should connect.4. when two of this lead and connectors and plural terminal are connected (under the normal condition, two and two here treat as a terminal with the upper conductor short circuit), 5V voltage enters instrument by several (not being one) leads, several pilot lamp are simultaneously bright, and pin the sound circuit of every lead correspondence by logical circuit, the sound circuit of " short circuit " sound is sent in triggering, and the operator has just known the lead short circuit, and has known which root lead short circuit by pilot lamp.

The beneficial effects of the utility model are: are connected with lead by touching, and fast convenient; Do not consider touching lead order, stop maloperation; Voice are pointed out in conjunction with pilot lamp, and man-machine interaction is more friendly, and reliability is higher.

Description of drawings

Below in conjunction with drawings and Examples utility model is further specified.

Accompanying drawing is circuit theory diagrams of the present utility model.

Embodiment

In the accompanying drawing, the wire harness of forming with 3 leads is an example, and 3 leads are respectively red, yellow, blue.Receive respectively on the instrument terminal of representing red yellow blueness with yellow blue 3 leads of the redness of the supporting frock of wire harness connector, represent red yellow blue instrument terminal R, Y, B to go into 0V by a current-limiting resistance and a light emitting diode series connection respectively, R, Y, B are as the input end of logical circuit, input end adds result 〉=2 o'clock entirely, logical circuit output F1 end is high level, and the F2 end is low level; Input end adds result＜2 o'clock entirely, logical circuit output F1 end is low level, F2 end is high level, R, Y, B also respectively with logical circuit output F2 end as with the input of door AND1, AND2, AND3, be respectively P1, P2, P3 with the output of door AND1, AND2, AND3.Logical circuit output F1 reaches with door output P1, a P2, P3 and joins with " short circuit ", " redness ", " yellow ", " blueness " sound circuit high level trigger end SBT respectively, each sound circuit audio voltage output terminal is attempted by on the audio frequency potentiometer, the contact voltage of audio frequency potentiometer outputs on the audio power amplifying circuit, the output of audio power amplifying circuit is received on the loudspeaker, and the two ends and the dual-channel headphone interface of loudspeaker join simultaneously.
