The statement of research and development is subsidized about federal government
It is not applicable.
Invention field
The present invention relates to the test equipments of electronic building brick, more specifically to a kind of relay contact analog control system automatically configured Instrument.
Background of invention
Relay is the mechanical device used in a plurality of types of equipment, automobile etc., makes low-power level signal can be with Control relatively large power termination.For example, controlling preceding circuit for lamp usually using relay in automobile circuit.By automobile The lamp switch of driver's operation is connected to the input or coil sides of relay.The input side is needed from the opposite of light switch circuit A small amount of power.When head light switch is switched on position, power supply is applied to coil, and the longitudinal axis of coiling is caused to generate magnetic field The ferrous metal pole piece for attracting relay outlet side in turn, leads to contact variable condition, this leads to headlight closing of circuit, thus It powers to the preceding circuit for lamp of relative high powers.In fact, the relatively small power control transmitting drawn from preceding light switch circuit To the relatively high power of headlamp circuit.It is such to be configured to entire industry and equipment, automobile, tool, automation equipment All different types of electrical/electronics controls in and the substantially any equipment for needing certain type of mid power control.
Each electrically or electronically circuit comprising relay can generate test problem to determine failure cause, especially work as When faulted circuit belongs to the type of automobile, so that can not access can examine when circuit is in operation or " electrification " state The test point looked into.All relay circuits are made of control (coil) and load-side.All relays all include one by controlling The coil of circuit power supply processed, the control circuit make at least one mechanical contact of relay operation again, keep the load circuit of connection logical It crosses the operation of mechanical contact and is powered or powers off.When such circuit when something goes wrong, it is necessary to check in circuit different The voltage and current of position, the reason of to determine problem.If there is the test point being readily accessible in circuit by chance, can be used Voltmeter and ammeter (digital multimeter-DMM) carry out the electricity of display circuit.It is using the shortcomings that DMM time-consuming and special It is difficult to obtain current reading in alive circuit.DMM also can not automatic measurement relay, to determine whether relay itself has The reason of failure and fault.
There is the relay tester for executing auto-relay test currently on the market.My " Relay BuddyTM", the U.S. The patent No. 9423462 is exactly best example.The present invention is the improvement to such device, because in measured relay (RUT) interface is produced between relay tester itself.
Relay tester currently on the market all includes some general-purpose relay sockets, therefore RUT can simply be put Enter in socket appropriate, so that the electric component of RUT to be exposed in relay tester to the appropriate location for testing circuit.For The relay tester of these types, it is desirable that RUT can be fitted into particular relay socket to be tested.Relay BuddyTMMark With 3 kinds of certain types of relay sockets or testable terminal layout " footprint ".Relay BuddyTMAlso have other relays Device footprint adapter can test the relay of other several types by the way that RUT terminal to be aligned with correct test jack terminal Device.The all objects of prior-art devices all include a fixed device or multiple fixed devices, with allow RUT with it is controlled, Known and repeatable method is connected to relay tester.
This is the real limitation of this current relay tester.The relay that can be tested is only can be with test The adapter that the footprint appropriate that instrument provides matches or they are necessary to allow for relay to be suitble to properly terminated position.
All relays all include a coil, which is powered to generate magnetic field, this pulls the electricity of relay switch again Pivot or pole piece are mobile, close or open so as to cause electrical connection.When the power supply removal for relay power, magnetic field will lose It loses and armature will return to its home position under certain type of spring force, and generate initial " power-off " or " normal " again Electrical connection state.Therefore, all relays all include coil sides and switch-side.The relay of most of Hyundai Motor types All comprising one common " footprint ", this is put into the component of relay no matter when in circuit can correctly and repeatably Positioning.It the use of the automobile of relay and most of other equipment include " socket ", this allows relay to have usually and suitably matches The tie point set enters circuit.
In addition, all relays all include coil and switch, but there are many that different types of for exposing relay " footprint " or the configuration of a little common assemblies.The magnitude of current according to relay design for processing, it may be opened comprising exposed circuits Close the relatively large terminal of side.Some relays designed for being loaded beyond 100 amperes, which usually have, uses big circle The switch of screw terminal connects.
The not stringent wiring standard of modern relay causes terminal name/size to become common known location or function Energy.For success busy relay, it is necessary to there is an adapter, relay terminal appropriate is made to be connected correctly to tester, with Just tester knows which which terminal is.
Therefore, it is necessary to the relay test-devices that one kind can be quickly connected to relay, without knowing relay What each terminal is.Required invention will have easy to use and intuitive control, and can quickly test 4- terminal or 5- final impulse optor program provides clear indication when such relay successfully passes or does not pass through test.The present invention is opposite to be held Easily it is used together with Vehicular battery or on-vehicle battery.The present invention realizes these purposes.

Due to " introduce time lag " of relay, controller be adapted to carry out quick counter relay change state it The preceding quantity by the electrical lead being grounded caused by a wire ground.Wherein, when relay coil state changes, armature is not It can move immediately.Controller applies also for realizing by a wire ground and the alternating of the electrical lead quantity of ground connection is caused slowly to be counted Number waits until armature traveling time once relay has changed state.
Preferably, test circuit further includes voltage regulator, for electric to test when supply voltage is higher than component voltage Road provides component voltage, such as volt.If power supply lead wire is connect with the wrong side of external power supply unintentionally, two can also be used Pole pipe bridge corrects the polarity of component voltage.In some embodiments, thus it is possible to vary resistor is to adapt to have 12 volts or 24 The external power supply of the voltage of volt etc..
Preferably, once controller determines which electrical lead is connect with relay coil, it is predetermined that controller is suitable for operation Number, such as ten circulation relay contact analog control systems.Therefore, if each circulation relay contact analog control system passes through, controller point brilliant green Color LED, or if any circulation relay contact analog control system fails, controller lights red LED.
In use, each electric terminal of relay is connected to a lead of test circuit, and relay-type is opened The relay types for being set as testing are closed, and in the case where test starting switchs and starts, controller be can be set often A electrical grounding, in turn, then calculated result leads to the quantity of other wire grounds.Then, controller lights at least one Indicator, to indicate the relay contact analog control system of the relay contact analog control system passed through or failure based on the counting of measurement.
For 5- terminal type relay, and in the case where relay power-off, test circuit determines five leads first Which of connected with substantially zeroed resistance, they are then appointed as normally closed lead.Then, test circuit is successively mutual Ground connection has substantially infinitely great resistance to check when normally closed lead is opened.This shows that at least having found a coil draws Line.Once it is determined that coil lead, then coil can in circulation relay contact analog control system circulation with identify other leads and Usually by ten circulations come busy relay.If any test crash, red LED is lighted to indicate that relay contact analog control system loses It loses;Otherwise green LED is lighted to indicate that test passes through.
The present invention is a kind of relay test-device, can be quickly connected to relay, and does not have to know relay What each terminal is.The present invention includes easy to use and intuitive control, and can quickly test 4- terminal or 5- terminal Relay provides clear indication when such relay successfully passes or do not pass through test.The present invention is relatively easily and vehicle Battery or on-vehicle battery are used together.In conjunction with attached drawing, the principle of the present invention is illustrated by way of example, by following More detailed description, other features and advantages of the present invention will become obvious.

Specifically, for 4- terminal type relay 20, following steps is taken to come busy relay 20 (Fig. 4):
1, tester 10 as described above is provided.
2, each electric terminals 21,22,23,28 of relay 20 are connected in five electrical leads 120 of test circuit 60 One.It is unimportant which of four electrical leads 120 are connected to each terminal 21,22,23,28, simplifies relay survey The setting of examination.
3, relay-type switch 110 is arranged to first position to indicate the 4- terminal type relay 20 tested.
4, supply voltage VS is suitable for test circuit 60, and thus each lead 120 is connect with supply voltage VS.
5. starting test starting switch 100.
6, then, test circuit 60 is tested the voltage to ensure power supply 80, and especially if with test circuit The voltage of the external power supply 82 of 60 connections is within the scope of preset appropriate voltage, such as about 12-15.5V.If it is not, test Circuit 60 lights at least one indicator 90 with instructed voltage fault state, such as by flashing red LED 92, and stops Test.
7, then, the first electrical lead 121 is by being grounded and waiting at least scheduled armature movement time by test circuit 60, Such as one second, the Lai Zhihang first round tests.
8, then, test circuit 60 is successively grounded other each electrical leads 120, and the lead 120 of quick counter ground connection Quantity.Then, test circuit 60 adds each counting to determine whether count is 10, if it is, jumping to step 10.
9, then, test circuit 60 repeats step 7 in next round test by being grounded next electrical lead 122, according to This analogizes, until there are five electrical leads 120 to be so grounded for institute.
If 10, not testing round result count is 10, circuit 60 is tested by red LED 92 and is set to indicate that mistake The relay contact analog control system 180 that loses simultaneously stops testing.
11, circulation relay contact analog control system 210 in some embodiments, is carried out at this time, this will be described hereinafter.

The relay 20 that the relay contact analog control system 210 of circulation tests pre-determined number is powered and then relay 20 powers off, measurement electricity Pivot terminal 23, normally opened terminal 28 and if there is normally-closed terminal 29 between conductivity or resistance circulation.Once it is determined that It is connected to after the electrical lead 120 on relay coil 26, the relay contact analog control system 210 of circulation could be executed.In above-mentioned steps, Any test round for being counted as 10 is caused to ensure that two ground leads 120 are connected on coil 26.In this way, when to coil 26 Be powered and power-off when and by by the electrical lead 120 for corresponding to armature terminal 23 be set as ground connection when, armature terminal 23 and often The conductivity or resistance opened between terminal 28 can test.Similarly, when to the energization of coil 26 and power-off and by that will correspond to In the electrical lead 120 of armature terminal 23 be set as ground connection when, can test armature terminal 23 and if there is normally-closed terminal 29 Between conductivity or resistance.It is normal in the relay 20 in work in the case where relay coil 26 is in energized state Opening terminal 28 initially will disconnect with armature 27 and will show zero voltage drop or essentially infinite big resistance.Once armature movement Time has occurred and that and relay 20 has changed state, and the normally opened terminal 28 of the relay 20 in work will be with 27 electricity of armature Connect and will show the voltage drop of supply voltage VS, or substantially zero resistance.Relay 20 is repeated to be powered and be powered off, and And remaining lead 120 is correspondingly tested, to ensure that relay 20 works normally.If any circulation relay contact analog control system 210 loses Effect, then red LED 92 is lighted and tests stopping.Otherwise, green LED 91 is lighted to indicate through relay contact analog control system 170.
For 5- terminal type relay 20, following steps busy relay 20 (Fig. 5):
1, tester 10 as described above is provided.
2, each electric terminals 21,22,23,28,29 of relay 20 are connected in five electrical leads 120 of test circuit 60 One.It is unimportant which of five electrical leads 120 are connected to each terminal 21,22,23,28,29, simplifies relay The setting of device test.
3, relay type switch 110 is arranged to the second position to indicate 5- terminal type relay 20.
4, supply voltage VS is applied to test circuit 60, and thus each lead 120 is connect with supply voltage VS.
5, start test starting switch 100.
6, then, test circuit 60 tested the voltage to ensure power supply 80, especially external power supply 82, if its with The test connection of circuit 60 is such as the about 12-15.5V within the scope of scheduled appropriate voltage.If it is not, then test c1 circuit 60 light at least one indicator 90 with instructed voltage fault state, such as by flash red LED 92, and stop testing.
7, test circuit 60 is executed often by the number of leads of the first electrical lead 120 of ground connection ground connection and quick counter ground connection Close test.If being counted as 2, controller 61 jumps to step 10.
8, normally closed test is repeated with next electrical lead 120.
If 9, all electrical leads 120 have been grounded in normally closed test and have not been counted as 2, testing circuit 60 will be red Color LED 92 is set to indicate that the relay contact analog control system 180 of failure and tests stopping.
10, two electrical leads that discovery is grounded in normally closed test are known as normally closed lead 23,29.
11, now, test circuit 60 by by remaining three electrical leads 120 ground connection rather than normally closed lead 23,29 connect Ground carrys out search coil 26, tests whether normally closed lead 23,29 now is opened.If it is, then ground lead is coil lead 21,22, and if any one of remaining two leads 120 are connected to any of normally closed lead 23,29, The lead of the two connections is normally opened lead 23,28.Common lead between normally closed lead 23,29 and normally opened lead 23,28 refers to It is set to armature leads 23.Test circuit 60 jumps to step 13.
If 12, normally closed lead 23,29 during the step 11 from being not switched on, test circuit 60 be arranged red LED 92 with It indicates the relay contact analog control system 180 of failure and tests stopping.
13, the relay contact analog control system 210 in some embodiments, recycled at this time, as mentioned before.
14, setting green LED 91 is to indicate through relay contact analog control system 170, and stops testing.
When determining whether the electric terminals 23 connecting with armature 27 are in electrical contact with such as normally-closed terminal 29, analog-digital converter Voltage drop on 140 switch endpoints 23,29 is to check whether it reads essentially zero volt.However, due to the touching in relay 20 The poly- (not shown) of contact wear and carbon deposit on point, there may be slight resistance between terminal 23,29, in this case, The voltage read at normally-closed contact 29 can be slightly higher than zero volt.In this way, test threshold voltage Vc can be set, so that super The resistance for crossing particular value leads to test crash, and seeming terminal 23,29 they are not is electrical contact, but due to contact carbon Accumulation.
