Background technology
At present, the test of magnetic latching relay is mainly undertaken by the tester of oscillograph and comprehensive relay, does not also have special-purpose testing tool to test its sensitivity.But, when magnetic latching relay being tested, owing to there is not unit clamp with the tester of oscillograph and comprehensive relay, not only operating process is loaded down with trivial details, and speed is slow, and data presentation is not directly perceived, the operator is had relatively high expectations, and equipment is relatively more expensive, cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind ofly can simplify the test job process, improves test job efficient, reduces the pulse test instrument of testing cost.
For solving the problems of the technologies described above, a kind of pulse test instrument of the utility model comprises panel, pulsewidth time showing district, the DC voltage viewing area, the voltage knob, the pulsewidth knob, work/check key, relay socket interface and relay socket, described pulsewidth time showing district, the DC voltage viewing area, the voltage knob, the pulsewidth knob, work/check key, the relay socket interface is located on the described panel, described relay socket comprises the relay testing button, the power work status indicator lamp, relay coil pin contact condition pilot lamp, relay movable contact spring socket, relay static contact spring piece socket, relay fixing feet patchhole and relay coil pin socket, described relay socket links to each other with described relay socket interface.
Above-mentioned a kind of pulse test instrument, it also comprises pulsewidth stepping key, it is located on the described panel.
Above-mentioned a kind of pulse test instrument, it comprises that also relay contact closure disconnects pilot lamp, it is located on the described panel.
The utility model during use, is connected to relay socket in the relay socket interface energized owing to adopted above-mentioned technical pattern.Then relay is inserted relay socket, pulse and the voltage of selecting the practical working situation with pulsewidth to be complementary by voltage knob and pulsewidth knob.Like this, the pulsewidth of relay and voltage just can be detected, and show in real time in pulsewidth time showing district and DC voltage viewing area.Thereby, utilize the utility model tester can not only simplify the test job process, improve test job efficient, and reduced testing cost, can be effectively applied to the magnetic latching relay sensitivity test, the voltage of being failure to actuate, operation voltage, the action pulse width that comprise magnetic latching relay, the isoparametric test of motionless pulse width.Simultaneously, its product of also going for paired pulses control is done the burst length test.

Embodiment
As shown in Figure 1, the pulse test instrument comprises that panel 9, pulsewidth time showing district 1, DC voltage viewing area 2, voltage knob 3, pulsewidth knob 4, work/check key 5, pulsewidth stepping key 6, relay socket interface 7, relay contact closure disconnect pilot lamp 8 and relay socket 10, and pulsewidth time showing district 1, DC voltage viewing area 2, voltage knob 3, pulsewidth knob 4, work/check key 5, pulsewidth stepping key 6, relay socket interface 7 and relay contact closure disconnect pilot lamp 8 and be located on the panel 9.The minimum displayed value 1ms in pulsewidth time showing district 1, the minimum displayed value 0.1V of DC voltage viewing area 2, voltage knob 3 can be in 3.3~27V scope the required operating voltage of step-less adjustment.After presetting the pulsewidth stepping, pulsewidth knob 4 can stepless fine tuning pwm value.When work/check key 5 was in the working position: press the testing button 11 of relay socket 10, power supply provided setting voltage to measured relay.When work/check key 5 was in correction position: the selected pulsewidth of power supply cycle detection also showed so that set.Pulsewidth stepping key 6 is provided with third gear: 10ms, 100ms and 1s.Relay socket interface 7 is used for being connected with relay socket 10.When the lamp of relay contact closure disconnection pilot lamp 8 is bright, represents relay contact in off-state, otherwise represent that then relay contact is at closure state.
As shown in Figure 2, relay socket 10 comprises relay testing button 11, power work status indicator lamp 12, relay coil pin contact condition pilot lamp 13, relay movable contact spring socket 14, relay static contact spring piece socket 15, relay fixing feet patchhole 16 and relay coil pin socket 17.Whenever press primary relay testing button 11, export a pulse.Power work status indicator lamp 12 is a red led, is the dynamic pilot lamp under the power work state.Relay coil pin contact condition pilot lamp 13 is a green indicating lamp.After pressing relay testing button 11,, show that relay is in work if red light, green light are bright entirely.If singly there is green light bright, the loose contact of expression relay coil pin.If green light does not work, show that the pulse power does not insert.Relay movable contact spring socket 14, relay static contact spring piece socket 15, relay fixing feet patchhole 16 and relay coil pin socket 17 are respectively applied for movable contact spring, static contact spring piece, fixing feet and the coil pin of relay and link to each other.
As shown in Figure 3, power supply produces voltage by three-port variable voltage regulator, operating voltage is provided, monostable circuit produces power pulse through oscillator, and pulse width is regulated delay control circuit by the decision of monostable time delay control circuit, can select pulse width, by automatic identification device, identification relay normality makes the pulse of relay consistent with relay status.By start button, produce pulse by monostable circuit, drive relay through pulse selecting circuit, display shows pulse width and voltage, finishes once test.
