As preferably, the bottom of described carriage release lever is fixed with operating grip, on described action bars, is provided with chute, and described operating grip is positioned at chute.
As preferably, in described fixing fixture block and the groove of movable clip block, be at least provided with respectively 2 root puncture pins.
Further, described puncture needle is equal in length.
As preferably, described groove is semicircle.
To sum up, the beneficial effects of the utility model are:
1, the cooperation of the fixing fixture block of the utility model utilization and movable clip block, to the puncturing of insulated wire, realizes the reliable ground of cable line, guarantees operating personnel's personal safety.
2, the operation carriage release lever that passes through of the present utility model, makes movable clip block under the drive of connector, coordinates cable is clamped and penetrated with fixing fixture block, and it is simple to operate.
3, on the groove limit of fixing fixture block of the present utility model and movable clip block, be provided with magnetic patch, magnetic patch attracts each other, strengthen fixing fixture block and the clamping action of movable clip block to cable, while avoiding carriage release lever not being controlled, movable clip block activity loses clamping action to cable, guarantees personal security.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the fixing fixture block of the utility model and the movable clip block structural representation when not closed.
Structural representation when Fig. 2 is the fixing fixture block of the utility model and movable clip block closure.
Mark and corresponding parts title in accompanying drawing: 11, fixing fixture block; 12, movable clip block; 2, magnetic patch; 3, puncture needle; 4, fixed block; 5, connecting rod; 6, connector; 7, carriage release lever; 71, operating grip; 8, action bars.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but execution mode of the present utility model is not limited to this.
Embodiment 1:
A kind of earth connection as depicted in figs. 1 and 2, comprise fixing fixture block 11 and the movable clip block 12 matching with fixing fixture block 11, on described fixing fixture block 11 and movable clip block 12, be provided with groove, on described fixing fixture block 11 and the groove limit of movable clip block 12, be provided with magnetic patch 2, in described groove, be provided with puncture needle 3, described fixing fixture block 11 is fixed on fixed block 4, on described fixed block 4, be fixed with action bars 8, in described action bars 8, be provided with carriage release lever 7, described movable clip block 12 is movably connected on carriage release lever 7 by connector 6, between described connector 6 and fixed block 4, be connected with connecting rod 5, on described fixed block 4 or fixing fixture block 11, be provided with ground wire connecting device.
In the present embodiment, under the movement of carriage release lever 7, movable clip block 12 coordinates with fixing fixture block 11, by cable clamp in groove, puncture needle penetrates the insulating barrier of cable and contacts with conductive layer, and ground wire connecting device connects earth connection, can realize the reliable ground of cable.
The course of work of the present embodiment is as follows, ground wire connecting device is connected to the ground by wire, control operation bar 8 on the other hand, control operation bar 8 moves up on the other hand, drive one end of connector 6 to move up, owing to being connected with connecting rod 5 between connector 6 and fixed block 4, the other end of connector is moved down, be that movable clip block 12 moves down, movable clip block 12 can be close with fixing fixture block 11, puncture needle can penetrate the insulating barrier of cable with conductive layer and contact, and realizes reliable ground, as shown in Figure 2.On groove limit due to fixing fixture block 11 and movable clip block 12, be provided with magnetic patch 2, magnetic patch 2 strengthens the attraction of fixing fixture block 11 and movable clip block 12, make movable clip block 12 be difficult for moving up, even after operating personnel let go, fixing fixture block 11 and movable clip block 12 still can coordinate cable is clamped.
Embodiment 2:
A kind of earth connection as depicted in figs. 1 and 2, the present embodiment is on the basis of embodiment 1, and for the ease of carriage release lever is operated, the bottom of described carriage release lever 7 is fixed with operating grip 71, on described action bars 8, be provided with chute, described operating grip 71 is positioned at chute.Chute limits the shift position of carriage release lever, Stability Analysis of Structures while making its operation.
