Embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

As Fig. 1, Fig. 2, shown in Figure 3:

Controller 14 outsides are metal shell, and are firm reliable, can guarantee enough mechanical strengths, and case top is provided with two installing holes 5, can use screw that the ground lane controller is installed in the ground wire cabinet; The housing front is provided with three indicator lights 2, is respectively applied for power supply, communication and the switching lock state of indicating controller; Housing bottom is provided with two water joints 1 and is used for to the enclosure interior cabling; Enclosure interior is equipped with electromagnetic lock 4, electromagnetic lock 4 have one columnar structured, can use two pieces of screws and housing to tighten together, the circuit board 3 in the housing is welded on the electromagnetic lock 4, have control circuit above, can realize communication and function such as the control that unblocks.

Ground wire seat 16 outsides are metal shell, the outstanding rectangular block of housing is provided with two alignment pins 8, ground wire seat 16 inside are provided with card reading antennas 7, and card reading antennas 7 is welded on by line on the circuit board 3 of controller 14 and by the rectangular window on ground wire seat 16 housings and appears.

Controller 14 and ground wire seat 16 are connected by bolt.

The outside of ground wire clamping block 15 is a metal shell, housing is provided with a lock hole 11 and two location holes 12, lock pin 6 fits of lock hole 11 and electromagnetic lock 4, alignment pin 8 fits on location hole 12 and the ground wire seat 16, ground wire clamping block 15 inside are provided with electronic tag 10 and appear by the rectangular window on the housing, when ground wire clamping block 15 is placed on the ground wire seat 16, card reading antennas 7 is aimed at electronic tag 10, realizes connecting by the connecting line crimping between ground wire clamping block 15 and the ground wire 9.

When ground wire clamping block 15 is placed on the ground wire seat 16, two alignment pins 8 on the ground wire seat 16 are inserted in two location holes 12 of ground wire clamping block 15, so just having limited ground wire clamping block 15 can only move on alignment pin 8 is axially reverse, if electromagnetic lock locking this moment, lock pin 6 will be inserted in the lock hole 11 of ground wire clamping block 15, and ground wire clamping block 15 moves on alignment pin 8 is axially reverse and also is limited.So just realize the locking of ground wire clamping block 15, also realized the locking of ground wire 9 simultaneously.
