CN202712447U - Earth wire binding post - Google Patents

Abstract

The utility model discloses an earth wire binding post, comprising earth wires, setscrews, and a binding post which is a polyhedron and is provided with a threaded hole on each surface. The setscrews are screwed in the threaded holes. An earth wire connection is sleeved on the setscrews. The earth wires are compressed on the binding post when the setscrews are screwed. A lower part of the binding post is buried in soil. Earth wires of a plurality of electrical devices can be connected on one binding post. The binding post is normatively designed and can reach requirement for preventing electric leakage, so that the electrical devices are free of potential safety hazard when charged with electricity, and no personal accident would occur. The earth wire binding post has significant economic benefit and social benefit.

Description

Earth terminal

Technical field

The utility model is the protective device on the power equipment of oil field, is a kind of earth terminal.

Background technology

The oil field power equipment, great majority are worked in the open air, cause personal injury accidents in order to prevent oil field power equipment electric leakage, have connect ground wire on each oil field power equipment.Because what do not have that unified earth terminal, ground wire connect is all irregular, do not have the effect of leaking electricity of preventing, there is potential safety hazard, cause easily the electric leakage accident.

Summary of the invention

The purpose of this utility model is a kind of earth terminal of design, and the ground wire unification of many power equipments is connected on the binding post, avoids the generation of the problems referred to above.

The purpose of this utility model is achieved in that and comprises ground wire, setscrew, binding post, binding post is polyhedron, at each face screwed hole is set, setscrew is screwed in the screwed hole, earth connection point is enclosed within on the screw, when twisting setscrew ground wire is pressed on binding post, the binding post bottom is embedded in the earth.

The beneficial effects of the utility model are: the ground wire of many power equipments can be connected on the binding post, the binding post design specification can reach and prevents the requirement of leaking electricity, and does not have potential safety hazard during the power equipment energising, the personal safety accident can not occur, have significant economic benefit and social benefit.
