Protecgulum carries out operation of uncapping, so as to effectively prevent operating personnel from tearing protecgulum open by mistake and being impacted to latch portion.
Working method 1
During the use of electric-magnetic lock mechanism, latch switch is pressed by operator so that the spiral shell in blocking mechanism
Spool is powered, and causes dynamic iron core action to release to the spacing of hoodle, is moved rearwards by hoodle so that the entrance of electromagnetic lock to be opened,
The insert action of ground wire can now be carried out.Operator inserts ground wire, screws the external thread sleeve of ground wire, ground wire and ground
Line staking is touched and forms path, and plug is touched while promoting, plug side triggering microswitch, to external agency's outgoing signal, is treated
Ground wire is completed after insertion operation, and operator unclamps latch switch so that the solenoid power-off in blocking mechanism, causes dynamic iron core
Decline under the action of the spring, hoodle is carried out spacing so that ground wire locking is in lock body, so that the locking work(of electromagnetic lock
Energy.Corresponding, the method for taking ground wire is identical with aforesaid operations method.
When ground wire takes out from lock body, the effect that plug is directed through spring by guide finger is resetted, and now plug is answered
Ground wire entrance is blocked in position, and protective action is played to ground wire entrance, prevents outside moisture and impurity from entering lock body structure, so as to realize
Electromagnetic lock is real to ground wire entrance out of doors in use, no matter in ground connection working condition or disconnect under armed state
Now close, the function of preventing foreign matter from entering.
Further, because microswitch is arranged on plug both sides, when ground wire insertion promotes plug to move upwards, plug
Side wall triggering microswitch and, microswitch triggering and conducting stroke increase constant with microswitch parallel distance, stable enhancing, no
In the presence of over-pressed phenomenon, the service life of microswitch is effectively extended.
Working method 2
As shown in figure 5, when installing, grounding base 10 being welded on live earth conductor, then, adapter 13 is screwed to and connect
On ground connection copper nut 12 on ground seat 10, until adapter end flat 22 is developed with being grounded the plane 12 of copper nut root, from
And the in-site installation of earth wire pile is completed, as shown in fig. 7, in use, live ground wire 1 passes through and arrives adapter ground wire jack 11
Afterwards, together with wing nut 9 is screwed to the external screw thread 21 on adapter, and ground wire is fixed, in the insertion lock body of ground wire 1
Ground wire testing agency 14, ground wire testing agency 14 will detect that signal is passed by binding post 15, so as to complete to connect
The mounting of ground wire.
When repeatedly dismounting ground wire, cause ground due to more than 21 friction of external screw thread on wing nut 9 and adapter
The end of a thread 1 is installed loosely, now, can back out adapter 2, and ground wire installation can just be solved by re-replacing a new adapter
The problem of loosening.
