Description
Technical field
It is particularly a kind of to be used to detect EGR valve sensor moulding cover board the present invention relates to EGR valve detection technique field
Device.
Background technology
In engines exhaust gas recirculation（EGR）In system, ECU is calculated currently according to signals such as engine speed, oil masses
The aperture of egr system demand, the aperture size of EGR valve is controlled using the signal calculated, so as to adjust exhaust gas flow, is made
Exhaust gas returns to cylinder after being mixed in a certain ratio with fresh air and is recycled, to reduce gas in-cylinder combustion temperature and burning
Speed, further so as to reduce the discharge capacity of NOX.
EGR valve sensor cover board is that EGR valve motor, transmission mechanism and change gear etc. are sealed in EGR valve valve body
One piece of plastic plate, plastic plate one is the plug for 5 contact pins for connecting engine wiring harness, wherein 3 contact pins pass through inside respectively
The winding displacement of parcel is connected with wrapping up the EGR rotary angle transmitters of injection in the plastic plate, and in addition 2 contact pins are also by plastic plate
The winding displacement of portion's parcel is connected with the motor plug of cover board other end.Because cover sheet thickness is limited, and the winding displacement wrapped up inside cover board
For the inserts of bronze material, when some inserts there are during burr, may result in there is short circuit after parcel injection between contact pin can
Can property.Automobile ECU also the sensor to EGR valve and motor can carry out fault diagnosis, EGR respectively while controlling EGR valve
If any two all can directly trigger ECU alarms there are short-circuit conditions between five lines of valve.At present, produced in EGR valve
It there is no the equipment being detected to the circuit in sensor cover board in journey, can only wait until to carry out test just after the completion of EGR valve assembling
It can judge, when there is short circuit phenomenon, can only scrap, have impact on production efficiency, add production cost.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of dress for being detected to EGR valve sensor cover board
Put, so that sensor cover board detects the unqualified part of internal short-circuit before production procedure is flowed into, it is ensured that the conjunction of EGR valve
Lattice rate, improves the production efficiency of EGR valve.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
For testing the detection device of EGR valve sensor cover board, including the plug that is docked with sensor cover board and it is used for
The testing agency that the short-circuit condition of sensor cover board is tested and shown, the testing agency are connected by harness and plug
Connect；The p-wire of five conducting wires in connection sensor cover board is contained in the harness.
The above-mentioned detection device for being used to test EGR valve sensor cover board, the testing agency include base, are set on base
There is the disk with knob and send the alarm mechanism of short-circuit alarming, be provided with the disk in respective sensor cover board respectively
20 contacts of five conducting wire combination of two, knob are arranged in disk by axis pin, two contacts at knob both ends respectively with
Two contacts of a combination are in contact on disk.
The above-mentioned detection device for being used to test EGR valve sensor cover board, the alarm mechanism include being arranged on base
Indicator light, buzzer and the power supply being inlaid in base, each group on the indicator light, buzzer, power supply, knob and disk
The contact of conjunction, which is connected in series, forms detection circuit.
It is as follows as a result of above technical scheme, the invention technological progress.
The present invention is used for before EGR valve sensor cover board enters production process, its line condition is detected, is solved
The problem of can not accurately testing short-circuit conditions after insert injection moulding inside EGR valve sensor cover board, occurs, it is ensured that the qualification of EGR valve
Rate, improves the production efficiency of EGR valve, reduces the production cost of EGR valve.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in further detail.
It is a kind of to be used to test the detection device of EGR valve sensor cover board, its structure as shown in Figure 1, including testing agency with
Plug 2, testing agency are connected by harness 3 with plug, and the test of five conducting wires in connection sensor cover board is contained in harness
Line.Plug 2 is docked with sensor cover board 1, and testing agency is used to the short-circuit condition of sensor cover board is tested and shown, side
Just operating personnel quickly judges that EGR valve sensor cover board whether there is short circuit phenomenon.
Testing agency includes base 4, is provided with the disk 5 with knob 6 on base and sends the alarming machine of short-circuit alarming
Structure.20 contacts are provided with disk, the combination of two of five conducting wires in respective sensor cover boards is distinguished in 20 contacts, i.e.,
Pin1-pin2, pin 1- pin 3, pin 1- pin 4, pin 1- pin 5, pin 2-pin 3, pin 2- pin 4,
Pin 2- pin 5, pin 3- pin 4, pin 3- pin 5, pin 4- pin 5, this 10 groups of combinations are connected to the 20 of base 4
