The conductor neck contains a transition section and a chucking section. Width of the transition section is greater than width of the chucking section. The chunking section is gradually biased the hook top from a junction with the transition section. The ground wire has advantages of simple structure and high safety.
Description
Technical field
The utility model relates to work about electric power safe construction device field, particularly, relates to a kind of safe earth connection.
Background technology
in electric power system, earth connection is the important tool that ensures staff's safety for there is voltage unexpectedly on the equipment having had a power failure and circuit time.Existing earth connection, it is directly articulated on the copper bar of wire or cable.Existing earth connection, it comprises hook, is provided with the curved post of arc in hook, curved post clamps wire.But still there is certain risk in this clamping mode, be operating personnel or because misoperation upwards promotes earth connection, now wire can depart from curved post, make the wire cannot ground connection, if now send a telegram here on wire, can bring serious threat to operating personnel's safety.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure and safe earth connection.
The technical scheme in the invention for solving the above technical problem is:
A kind of earth connection, comprise the insulation body of rod and be fixed on the hook on the body of rod, on described hook, be fixed with wire connecting ring, on the gib head of described hook, be fixed with wire lower fixture, between described wire lower fixture and the hook of hook top, there is wire draw-in groove, described wire draw-in groove comprises changeover portion and fastening portion, and the width of described changeover portion is greater than the width of fastening portion, and described fastening portion is from being partial to gradually hook top with changeover portion junction.
As preferably, on the lower end of the described body of rod, be provided with shoe.
Further, described shoe is rubber.
As preferably, the width of described changeover portion is from the notch of wire draw-in groove to reducing gradually with fastening portion junction.
To sum up, the beneficial effects of the utility model are:
1, the utility model utilizes wire draw-in groove to fix wire, the upper and lower of wire is contacted respectively, even if upwards promote the body of rod with hook top, wire lower fixture, wire only can move in wire draw-in groove, be that wire can not depart from hook, effectively realize and connecing, strengthen its fail safe.
2, the width of changeover portion of the present utility model is greater than the width of fastening portion, is convenient to wire and snaps in fastening portion, be i.e. convenient operation.
3, of the present utility model simple in structure, easy operating.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A portion in Fig. 1.
Mark and corresponding parts title in accompanying drawing: 1, hook; 11, hook top; 2, wire connecting ring; 3, wire draw-in groove; 31, changeover portion; 32, fastening portion; 4, wire lower fixture; 5, the body of rod; 6, shoe.
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 the insulation body of rod 5 and be fixed on the hook 1 on the body of rod 5, on described hook 1, be fixed with wire connecting ring 2, on the gib head 12 of described hook 1, be fixed with wire lower fixture 4, between the hook top 11 of described wire lower fixture 4 and hook 1, there is wire draw-in groove 3, described wire draw-in groove 3 comprises changeover portion 31 and fastening portion 32, the width of described changeover portion 31 is greater than the width of fastening portion 32, and described fastening portion 32 is from being partial to gradually hook top 11 with changeover portion 31 junctions.
Hook comprises the coupler body, hook top 11 and the gib head 12 that connect successively, and one end of coupler body is connected on the body of rod 5.The lower end in contact of utilizing wire lower fixture 4 and wire, realizes the reliable ground of wire, though make the body of rod because of carelessness by push away, wire still can reliable ground, improves its fail safe.Between the hook top 11 of wire lower fixture 4 and hook 1, form wire draw-in groove 3, in order to reach the effective grounding of wire, the width of wire draw-in groove fastening portion 32 equates with diameter of wire.The diameter of general wire is 2 centimetres, and the width of wire draw-in groove fastening portion 32 is 2 centimetres.The width of changeover portion 31 is greater than diameter of wire, is convenient to wire and snaps in fastening portion, be i.e. easy operating.Fastening portion 32 is from being partial to gradually hook top 11 with changeover portion 31 junctions, in use the height of the bottom land in fastening portion 32 higher than the height of changeover portion, while making to be hung on wire, bottom land effectively contacts with wire, realize the reliable ground of wire, be also convenient to wire to snap in the bottom land of fastening portion.If when the height of the bottom land in fastening portion 32 lower than the height of changeover portion, is hung on wire, wire easily moves to notch direction along draw-in groove, although can realize under normal circumstances the ground connection of wire,, when in the time upwards promoting the body of rod, wire can depart from hook, the ground connection that can not realize wire.
In use, first earth lead is connected on wire connecting ring 2, controls the body of rod 5 earth wires and operate.The notch place that wire is placed in to wire lower fixture 4 and hook top 1, the notch place of wire draw-in groove 3, pulls the body of rod, makes wire along changeover portion 31 and fastening portion 32, enters bottom land, and it is simple to operation.Because wire lower fixture 4 and hook top 1 fixes wire at upper and lower end, even if make upwards to promote the body of rod, still good ground connection of wire.
Embodiment 2:
A kind of earth connection as depicted in figs. 1 and 2, for the ease of the body of rod is operated, the present embodiment, on the basis of embodiment 1, is provided with shoe 6 on the lower end of the described body of rod 5.
Described shoe 6 rubber.
Operating personnel are in the time carrying out operation, and the palm of the hand is easily perspired, and utilize shoe, increase the frictional force of the palm of the hand and the body of rod, convenient operation personnel operation.Adopt rubber, its low price and good antiskid effect.
Embodiment 2:
A kind of earth connection as depicted in figs. 1 and 2, the present embodiment, on the basis of above-described embodiment, makes the width of changeover portion 31 from the notch of wire draw-in groove 3 to reducing gradually with fastening portion 32 junctions.The width of the notch of wire draw-in groove 3 is greater than the diameter of wire, is convenient to wire to snap in wire draw-in groove 3, and the width of changeover portion 31 reduces gradually, makes itself and fastening portion smooth connection.
As mentioned above, can realize preferably the utility model.
