Road.Before power supply is connected (i.e. opening second source switch 32), the reversion button of first motor is first pressed, is pressing the second motor just
Turn button, and open the first power switch, then light emission component is mounted in device mounting base, connector is mounted on connector
In mounting base, power on (second source that can connect on power circuit switch, second source switch can be used as power circuit
Master switch powers on as second source is closed the switch, and second source switch is also that the art is common opens here
Close), when original state, insulated switch is in closed state, and rotary switch is in closed state, and the first circuit is because of two the first gold medals
Belong to separating for block and be in off state, second servo loop is in energized state, and the second motor starts Positive work, and screw rod is driven to turn
It moves and is displaced the device mounting base on screw rod towards connector mounting base, when the displacement of device mounting base installs seated connection with connector
When touching connection, the connector and light emission component matching connection, and two the first metal block contacts connect and make first
Power on circuitry, first motor start antiport, drive transmission shaft rotation, and after transmission shaft starts turning, rotary switch is because dynamic
Leaving for arm and it is in the open state, the second motor power-off and suspend operating；When transmission shaft goes to 180 degree, on the one hand, described
Connector and the light emission component are well-located by corresponding positioning plate, and on the other hand, insulated switch is rotated because of insulating trip
The insulated switch is in an off state between the elastic hollow metal block for being plugged in two contact connectios completely, at this moment the
One motor also start power off and make first motor pause operating, because connector and light emission component matching connection and it is well-located,
It can start to test, the one end of connector far from light emission component is tested for connecting fibre optic test instrument, after the completion of test, first
The rotating forward button of first motor is pressed, and presses the reversion button of the second motor, is closed the first power switch, first motor is logical
Electricity, at this point, being in an off state rotary switch because of the leaving for swing arm of rotary switch, the second motor is still powered off.First
Motor starts Positive work, and transmission shaft is driven to rotate clockwise, on the one hand openable first positioning plate and the second positioning plate, when the
One motor, which turns to 180 degree, can make the swing arm of rotary switch return to original state, be closed rotary switch again, and the second motor is again
Start antiport, screw rod is driven to rotate backward, so that device mounting base be made to be displaced far from connector mounting base, the second motor is anti-
Two the first metal blocks separate and power off first motor again when turning to start, can be when connector mounting base returns to initial position
Opening second source switch makes the second motor shut down again, opens simultaneously the first power switch, waits the present embodiment
TOSA fixture for testing is again coupled to other light emission components and connector, which, which can be repeated several times, makes
With.
