Abstract
The utility model discloses an anti-fall earth wire clamp, which consists of a U-shaped body, an earth wire fixing screw and a pressing screw, wherein the bottom surface and a side face of the U-shaped body are provided with a threaded hole respectively; the threaded hole on the bottom surface is matched with the earth wire fixing screw; the threaded hole on the side face is matched with the pressing screw; and the inner wall of the side face opposite to the side face on which the threaded hole is formed is cambered. The anti-fall earth wire clamp can be used on both a flat iron type earth component and a cylindrical earth component, has a wide application range, is in surface contact with the earth component, has a large contact area, and is firm in fixation and difficult to loose; an imperfect earth phenomenon due to virtual connection is avoided, and the safety of power and the personal safety are guaranteed. The anti-fall earth wire clamp is easy to operate and has high efficiency.
Description
Technical field
The utility model relates to a kind of earthing clamp.
Background technology
At present, high voltage test is mainly the fish mouth type wire clamp with earthing clamp, adopt spring structure, its contact area only has four length to be about 1cm, thickness only to be the half camber iron plate of 1mm, belong to line style contact, contact area is less, and takes place in use easily that the wire clamp spring breaks and the wire clamp centre is connected situation such as collapse out, thereby and cause testing ground connection disconnection being subjected to very easily to come off under the situation of external force, bring threat for the person and device security.
Summary of the invention
The purpose of this utility model is exactly to solve now with the problems referred to above that exist in the technology, provides a kind of contact area big, connection reliability height, long service life, the slip-off preventing earthing clamp of difficult drop-off.
For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of slip-off preventing earthing clamp, and it is by U-shaped body, ground wire fixed screw and hold out against screw and form; Have screwed hole on the bottom surface of U-shaped body and the side, screwed hole on the bottom surface and ground wire fixed screw are complementary, the screwed hole on the side with hold out against screw and be complementary, the side inner walls relative with the side of opening screwed hole is arc.
Above-mentioned described holding out against has handle on the screw, so that hand is tightened.
U-shaped body of the present utility model is connected on the grounded parts, holds out against on grounded parts by holding out against screw again, and connecting wires then is fixedly connected on the U-shaped body by the ground wire fixed screw.The utility model can use on band iron type grounded parts, can use again on cylindrical grounded parts, the scope of application is wide, with grounded parts is that face contacts, and contact area is big, and fixed, be difficult for getting loose, can not guarantee the safety of electric power, guarantee personal safety because of virtual connection produces the imperfect earth phenomenon.Simple to operate, the efficient height.
Description of drawings
Fig. 1 is a front view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, present embodiment holds out against screw 4 by U-shaped body 1, ground wire fixed screw 2 and band handle 6 and forms.Have screwed hole on the bottom surface of U-shaped body 1 and the side, screwed hole on the bottom surface and ground wire fixed screw 2 are complementary, the screwed hole on the side with hold out against screw 4 and be complementary, the side inner walls 5 relative with the side of opening screwed hole is arc.3 is ground wire.
