The battery main switch of device for opening；
By in the holding tank 2 of plastic embedding device；Plastic contacts and triggers contact switch 21, and signal K1 is passed by contact switch
Pass central controller 5, central controller 5 output signal QG controls lock-up cylinder 64 to do extending action, plastic is locked spacing
In holding tank 2；
After plastic locking, central controller output signal will represent the display lamp D1 point of first terminal hole needing plug-in mounting
Bright, instruction installation personnel installs insertion Wiring harness terminal to this terminal hole；
In Wiring harness terminal insertion terminal hole and contact squeeze silica gel head 31, and pressure is carried out by spring adjust to stablizing shape
After state, pressure transducer 33 stablize pressurized reach the specified time (such as two seconds), after reaching standard, pressure transducer by signal L1 pass
It is delivered to central controller, after central controller acquisition information, output signal controls this terminal hole corresponding display lamp D1 to extinguish, with
When output signal to Control valve, Control valve controls cylinder QG1 retraction, so that pressure transducer is declined and departs from and line
The contact of Shu Duanzi, the L1 signal interruption when pressure transducer completely disengages from Wiring harness terminal, central controller output signal controls
The corresponding display lamp D2 of next terminal hole position lights, and instruction installation personnel is according to operation；
Repeat upper two steps, until all terminal holes all plug-in mountings finish, central controller controls rebounding mechanism owns
Cylinder extending action, lifts pressure transducer to initial position, and central controller also controls lock-up cylinder to bounce back, and so that dead bolt is departed from
Plastic, the convenient plastic completing to install departs from holding tank, and plastic departs from the contact with contact switch 21, and central controller obtains
Return the incipient stage after signal, to meet the installation of next plastic.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
