Description

Plug and socket insertion testing device

Technical Field

The utility model relates to a plug and socket's inserting closes detection device.

Background

GB/T2099.1 states that the socket should withstand the mechanical, electrical and thermal stresses that occur during normal use without excessive wear or detrimental effects, so that in testing, it is necessary to test the test plug in suitable test equipment and to test the socket for the number of insertions and removals.

Due to the long test period of this project, during the process of inserting and pulling out the plug and the socket for many times, a large gap or dislocation may occur in the inserting and pulling-in between the plug and the socket. When a plug and a socket are plugged in the conventional socket life plugging and unplugging testing machine, a testing circuit of the plug and the socket on the testing machine is conducted, and if the condition that the testing circuit is broken or connected for a long time occurs, an alarm is triggered. However, in the process of multiple plugging tests, the plug and socket clamp may become loose, or the socket structure may be damaged, the plug and the socket may not be plugged completely or deviate, and the plug and the socket may still be connected under the above conditions, so the existing plugging test machine may not give an alarm. If the inspector does not detect the above, the testing will proceed erroneously. Therefore, in the test process, the condition that the plug cannot be completely inserted into the socket cannot be detected, and the real condition that the socket tolerates mechanical, electrical and thermal stresses generated in normal use cannot be completely checked.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a plug and socket's the test device that closes of inserting can detect out the plug and the not complete state of inserting the closing of socket in testing.

The utility model discloses a plug and socket' S insertion closes test device, including the testing machine that is used for fixed plug and socket, the fixed hall switch that is provided with on the plug, the surface paste of socket has magnet, hall switch with distance L = critical distance S between magnet, wherein, critical distance S is the critical position of hall switch output high level and output low level, promptly:

Invalid testing is avoided, and time is wasted, so that the testing result is inaccurate. The test procedure was as follows: in the test process, if the plug and the socket can be completely plugged, the Hall switch can send a high level signal at an interval period along with plugging, if the plug and the socket are not completely plugged, the relative position of the Hall switch on the plug and the magnet on the socket can deviate, the Hall switch cannot normally output the high level signal as before, the output signal of the Hall switch is continuously monitored by the controller, the alarm module can be switched on to give an alarm when the output signal of the Hall switch is abnormal, and a detector is reminded to adjust the position of the test plug.

The utility model discloses still have following preferred design:

the utility model discloses a controller is the singlechip, alarm module includes that the base is connected the PNP triode of singlechip output, the collecting electrode of PNP triode is connected with bee calling organ, bee calling organ ground connection. In the continuous complete insertion process between the plug and the socket, the output pin of the Hall switch can continuously output a high level to the single chip microcomputer, and if the high level continuously appears, the insertion is normal. When the plug and the socket are plugged, the time that the high-level signal does not appear all the time is not less than or equal to the preset time T, the single chip microcomputer can react at the moment, a low level is output to the PNP triode at the output end, the collector of the PNP triode is grounded, the voltage of the PNP triode is always 0, and the voltage of the emitter changes along with the change of the input voltage of the base, so that when the output end of the single chip microcomputer is at the low level, the voltage of the emitter of the PNP triode is at the low level, current passes through the buzzer, and the buzzer sounds to give an alarm.

The base of PNP triode with be provided with resistance between the output of singlechip.

As a possible embodiment of the present invention: the type of the single chip microcomputer is AT89C51.

The utility model discloses a hall switch is 3144 series hall switch.

The controller is provided with reset switch, and after alarm module reported to the police, the testing personnel obtained the accessible reset switch of warning back and reset, tests again behind the adjustment plug clamping position.

The beneficial effects of the utility model reside in that:

1. the utility model discloses a plug and socket's insertion test device, for the improvement device of current plug testing machine, need not to change the structure of current testing machine, great clearance or dislocation appear with the socket in the detectable plug in the process of the test, can not insert completely promptly and still can switch on test circuit's the condition, then send and warn, avoid invalid test, can accurately examine the socket and endure the real condition of mechanical, electric and thermal stress that appears when normally using.

2. Adopt triode, bee calling organ as alarm module, whole volume is less, the sexual valence relative altitude, and program control is convenient, and the circuit is simple, can continuously send out alarm sound, effectively reminds experimental personnel experimental socket and plug to appear inserting the problem and in time adjust.
