Description
Technical field
The present invention relates to connector wire harness finished product electric property detection device field, especially relate to a kind of break-make detector.
Background technology
The electrical property detecting instrument of existing such connector wire harness, can not remember in connector wire harness by the power of electric current, also just can not detect the so-called certified products (being to have a copper wire to connect also in multiply copper conductor can cause and show path to General Instrument) lower than rated current intensity.
Summary of the invention
The object of the invention is to overcome the above problems, a kind of break-make detector is provided.
Technical scheme of the present invention is:
Break-make detector, comprise main control system, input equipment, output device, the first wire harness adapter, the second wire harness adapter, the first multiselect switch, the second multiselect switch, first pair is selected switch, second pair is selected switch and power supply, described input equipment is connected respectively at described main control system data with described output device, First Line number converter is electrically connected to described main control system by the first multiselect switch, the second line number converter is electrically connected to described main control system by the second multiselect switch, described the first multiselect switch selects switch to be electrically connected to described first pair, described the second multiselect switch selects switch to be electrically connected to described second pair, described power supply selects switch to be electrically connected to described first pair, described second pair is selected switch ground connection.
Described input equipment comprises function button and scanner.
Described output device comprises display screen, printer and audible-visual annunciator.
Also comprise Insulation Resistance Tester, described Insulation Resistance Tester selects switch and described second pair to select switch to be electrically connected to respectively at described first pair.
Advantage and good effect that the present invention has are: the circuit design of this instrument is science very, and its manufacturing process is easy and cost is lower, maintenance is also very convenient, does not need very high professional technique.In connector wire harness industry, there are larger development and application space, and the quality of the similar products of the sector is also had to impetus simultaneously.

Embodiment
As shown in Figure 1, the present invention includes main control system 1, input equipment 2, output device 3, the first wire harness adapter 4, the second wire harness adapter 5, the first multiselect switch S 1, the second multiselect switch S 2, first pair is selected K switch 1, second pair is selected K switch 2 and power supply 6, described input equipment 2 is connected respectively at described main control system 1 data with described output device 3, First Line number converter 4 is electrically connected to described main control system 1 by the first multiselect switch S 1, the second line number converter 5 is electrically connected to described main control system 1 by the second multiselect switch S 2, described the first multiselect switch S 1 selects K switch 1 to be electrically connected to described first pair, described the second multiselect switch S 2 selects K switch 2 to be electrically connected to described second pair, described power supply 6 selects be electrically connected at 2 of K switch 1 with described first pair, described second pair of 2 ground connection selecting K switch 2.
Described input equipment 2 comprises function button and scanner.
Described output device 3 comprises display screen, printer and audible-visual annunciator.
Also comprise Insulation Resistance Tester 7, described Insulation Resistance Tester 7 is respectively at described first pair 1 and described second pair of 1 electrical connection selecting K switch 1 selecting K switch 1.
The course of work of this example:
1, the break-make of wire harness detects, in K switch 1, K2 is closed in 2 situation, by main control system automatic coding output, after treatment to multiselect switch S 1, S2 carries out gating control, be about to one group of gating of the S2 of multiselect switch, the wire harness being strobed so is just connected with 10V power supply by switch, by controlling another group multiselect switch S 2, can successively control wire harness is connected to the ground, by A/D, change K switch 1, the voltage transitions of K2 and power supply junction is digital signal, data being delivered to main control system processes again, if what S1 and S2 selected is same wire harness, wire harness conducting when the signal of sampling is low level, during high level, open circuit, if high when low during level, wire harness loose contact, as S1 and S2 choosing is different wire harness, wire harness short circuit when the signal of sampling is level, normal during high level, main control system is tested the relation of each wire harness part one by one, test structure is delivered to display screen to be shown.
2, megger test, digital insulation resistance instrument is connected with K switch 1, K2, during work, K1, K2 are closed into 1 place, main control system sends channel selecting signal, control multiselect switch S 1, S2 select wire harness, follow wire harness to add 500VDC power supply, and by K2, draw back resistance meter at the other end of wire harness by resistance meter, according to the resistance value of returning, judge whether to meet the requirements.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
