Description
Technical field
The utility model relates to a kind of wired earth line hook of the electric equipment both sides used when power equipment carries out high voltage test.
Background technology
When power equipment carries out high voltage test, the wire of electric equipment both sides needs to mount earth connection, and equipment side wire and ground wire are hooked together with clamp for ground wire by operating personnel, with the safety of protection test operating personnel.Existing clamp for ground wire is connected in pocket for the punch head by the spring card on hook by earth wire clip, in upkeep operation process, the wire of equipment both sides is often needed to untie, clamp for ground wire is under the effect of wire gravity, easy generation loosens and even comes off, and injures the personal safety of testing operation personnel.
Summary of the invention
The utility model provides a kind of clamp for ground wire preventing earth connection from coming off, and the wire solved when high voltage test on clamp for ground wire holds caducous technical problem.
The utility model solves above technical problem by the following technical programs:
A kind of clamp for ground wire preventing earth connection from coming off, comprise insulating bar, C type clamp are fixedly installed on the top of insulating bar, the lower surface of C type clamp is provided with push rod leading screw to be spirally connected through hole, push rod leading screw is bolted with in push rod leading screw is spirally connected through hole, wire apical grafting plate is fixedly installed on the top of push rod leading screw, the lower end outside of C type clamp is provided with bearing pin, bearing pin is hinged with fork, the outer end of fork is provided with fork screw, in fork screw, be bolted with fork set bolt, have fork connecting screw hole in the upper end arranged outside of C type clamp.
Fork is provided with side direction crimping lead wire screw, is bolted with side direction crimping lead wire screw rod in side direction crimping lead wire screw, the medial extremity of side direction crimping lead wire screw rod is provided with side direction crimping plate, and wire is crimped in C type bayonet socket.
The utility model is easy to operate, and installing/dismounting is quick, and hanging earthing conductor is safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the working state figure of the utility model after clamping wire.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of clamp for ground wire preventing earth connection from coming off, comprise insulating bar 2, C type clamp 1 are fixedly installed on the top of insulating bar 2, the lower surface 7 of C type clamp 1 is provided with push rod leading screw to be spirally connected through hole 3, push rod leading screw 4 is bolted with in push rod leading screw is spirally connected through hole 3, wire apical grafting plate 5 is fixedly installed on the top of push rod leading screw 4, the lower end outside of C type clamp 1 is provided with bearing pin 8, bearing pin 8 is hinged with fork 9, the outer end of fork 9 is provided with fork screw 10, fork set bolt is bolted with in fork screw 10, fork connecting screw hole 11 is had in the upper end arranged outside of C type clamp 1.
Fork 9 is provided with side direction crimping lead wire screw 12, side direction crimping lead wire screw rod 13 is bolted with in side direction crimping lead wire screw 12, the medial extremity of side direction crimping lead wire screw rod 13 is provided with side direction crimping plate 14, and wire 15 is crimped in C type bayonet socket 6.
The utility model is when not connection device wire, and the fork 9 of earth connection clamp is freely sagging, and after wire 15 enters C type bayonet socket 6 by C type clamp, fork 9 upwards closes, and is fixed by the fork connecting screw hole 11 of the upper end arranged outside of C type clamp 1.Rotate push rod leading screw 4, thus drive apical grafting screw mandrel to move up, wire 15 is held out against by the wire apical grafting plate 5 of apical grafting screw mandrel upper end in the vertical direction.Rotate cross-under side direction crimping lead wire screw rod 13 on fork 9 again, drive in side direction crimping lead wire screw rod 13 guiding line bayonet socket mobile, wire is held out against in the lateral direction.The utility model serves restriction wire and moves in earth connection clamp, reaches the object preventing earth connection from coming off.
