Abstract
The utility model relates to a wire clamp. The objective of the utility model is to provide a grounding wire clamp which has the advantage of simple structure and is provide with a movable clamping chuck. The double-reed bayonet type grounding wire clamp of the utility model comprises an insulating rod and a clamping chuck. The clamping chuck is a bayonet type clamping chuck, the bottom of the clamping chuck is provided with a connecting rod, an annealed copper wire is wound onto the connecting rod, a U-shaped clamping chuck slot is fixed at the top portion of the insulating rod, the clamping chuck slot is composed of a slot baseplate and two opposite slot side plates, slot screw holes are formed in the two slot side plates at corresponding positions, the connecting rod is inserted and installed between the two slot side plates, a connecting rod screw hole is formed in a portion of the connecting rod which corresponds to the slot screw holes, and a bolt passes through the slot screw holes and the connecting rod screw hole to hinge the insulating rod and the clamping chuck together. The double-reed bayonet type grounding wire clamp of the utility model can be used to clamp a wire in the vertical direction conveniently.
Description
Technical field
The utility model relates to a kind of wire clamp, particularly relates to a kind of wire clamp that electric wire is connected with ground wire when overhauling for electric wire.
Background technology
When electric power apparatus examination; usually in the safety of the both sides of equipment clamping connection ground wire with the assurance maintainer; the whether unimpeded safety that is related to the maintainer of earth connection to some degree; earth connection connects with electric wire by earthing clamp; existing earth connection accompanies two kinds; a kind of is the two-man act bayonet type; a kind of is the spiral compression formula; wherein the two-man act bayonet type is because simple in structure; obtained general application; does existing two-man act bayonet type earthing clamp comprise one? the chuck of type and an insulating bar that is fixedly connected with chuck; the recess of chuck upper end arranges two intermediate plates, electrical wire clip can be held between two intermediate plates, is grounded the UNICOM of line and electric wire; for electric wire parallel to the ground; this simple in structure; easy to operate, but when electric wire was vertical direction, the effect that is clamped and connected of this two-man act bayonet type earthing clamp and electric wire was just had a greatly reduced quality; come off easily crisis maintainer's safety.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, with the earthing clamp of active chuck.
The utility model two-man act bayonet type earthing clamp, comprise insulating bar and chuck, described chuck is the bayonet type chuck, described chuck bottom arranges connecting rod, twine annealed copper wire on the described connecting rod, U-shaped chuck draw-in groove is fixed at the top of described insulating bar, described chuck draw-in groove is comprised of the draw-in groove base plate draw-in groove side plate relative with two, respectively offer a draw-in groove screw on described two draw-in groove side plate correspondence positions, the described connecting rod of plug-in mounting between described two draw-in groove side plates, the corresponding described draw-in groove screw of described connecting rod place offers a connecting rod screw, and bolt passes described draw-in groove screw and connecting rod screw makes described insulating bar and chuck hinged.
Compared with prior art, the utility model chuck and insulating bar are hinged by bolt and screw, and chuck can rotate by 180 degree, makes things convenient for the especially electric wire of vertical direction of the various angles of clamping connection.
The utility model two-man act bayonet type earthing clamp, wherein said bolt comprises nut, described nut is wing nut.Adopt wing nut be for free-hand just can rotating nut.
The utility model two-man act bayonet type earthing clamp, wherein said chuck is aluminum design.The chuck good conductivity of aluminum design, resistivity is low, and is corrosion-resistant.
The utility model two-man act bayonet type earthing clamp, wherein said connecting rod is being coated with metal copper layer with described annealed copper wire joint face, is coated with the copper layer on the connecting rod and is to reduce resistance and heating when being connected with annealed copper wire.
Below in conjunction with accompanying drawing the utility model two-man act bayonet type earthing clamp is described further.
Description of drawings
Fig. 1 is the utility model two-man act bayonet type earthing clamp broken away view;
Fig. 2 is the utility model two-man act bayonet type earthing clamp chuck activity diagram.
Embodiment
As shown in Figure 1, the utility model two-man act bayonet type earthing clamp comprises insulating bar 1 and chuck 2, chuck 2 is the bayonet type chuck, chuck 2 is aluminum design, chuck 2 bottoms arrange connecting rod 21, twine annealed copper wire 5 on the connecting rod 21, connecting rod 21 is being coated with metal copper layer with annealed copper wire 5 joint faces, U-shaped chuck draw-in groove 11 is fixed at the top of insulating bar 1, chuck draw-in groove 11 is comprised of a draw-in groove base plate 111 draw-in groove side plate 112 relative with two, respectively offer a draw-in groove screw 113 on two draw-in groove side plate 112 correspondence positions, plug-in mounting connecting rod 21 between two draw-in groove side plates 112, connecting rod 21 corresponding draw-in groove screws 113 places offer a connecting rod screw 211, and bolt 3 passes draw-in groove screw 113 and connecting rod screw 211 makes insulating bar 1 and chuck 2 hinged, bolt 3 arranges nut 31, and nut 31 is wing nut.
As shown in Figure 2, the utility model in use, when electric wire is parallel to the ground, directly with chuck of the present utility model 2 and electric wire clamping connection, when electric wire and ground at an angle the time, rotating nut 31, the bolt 3 of outwarding winding is adjusted the angle of chuck 2, when the intermediate plate in the chuck 2 is vertical with electric wire, and rotating nut 31, fix chuck 2, by insulating bar 1 chuck 2 is clamped on the electric wire.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
