Abstract

The utility model discloses a novel ground clamp belongs to the power supply field. Including collet body, last left elasticity clamping piece, right elasticity clamping piece, action bars joint and the ground wire stiff end of being equipped with of collet body still includes U -shaped fender piece, the open end that the U -shaped kept off hinges on collet body, and the U -shaped keeps off another pot head at the collet body opening part, be fixed with the ground connection spare of one end perk on the ground wire stiff end. The utility model discloses the potential safety hazard of not only having avoided the wire to drop from the ground clamp, can also be convenient pick up the action bars with the insulator spindle and connect has improved work efficiency.

Description

Novel ground clamp

Technical field

This utility model belongs to a kind of power system instrument, specifically, particularly relates to a kind of novel ground clamp.

Background technology

In the production activity of power supply enterprise, hanging of ground wire is the front required preparation of maintenance, is to ensure that line construction personnel And the important measures of maintainer's personal safety.Earthing clamp is a kind of electric power safety instrument for mounting short-circuit grounding wire, when When high pressure equipment carrying out interruption maintenance or carries out other work, short-circuit grounding wire can prevent equipment from sending a telegram here suddenly produced danger Voltage and electric arc, prevent neighbouring high voltage alive equipment and circuit from producing the induced voltage harm to human body, can also be used with to drain power-off Equipment and the residual charge of circuit, it is to avoid personnel get an electric shock and die or third-degree burn, to ensure the personal safety of operating personnel.At present The earthing clamp used includes that wire clamp, wire clamp lower end are fixedly connected with insulating bar by fixing end, is designed with double tongue spring in wire clamp, There is following defect in this structure: one is that this structure only leans on double tongue spring compression wires, without other slip-off preventing measure, if outside having The masterpiece used time is easy to make wire clamp come off, and there is potential safety hazard；Two is owing to not allowing the tactile wire clamp that catches, it is therefore desirable to absolutely Edge bar is picked up, and the gnd conductor of this structure is fixed on ground clamp by fixing end, and gnd conductor is almost fitted on ground clamp, Insulating bar is picked up very inconvenient.

Utility model content

This utility model purpose is to provide a kind of novel ground clamp, exhausted with inconvenience to overcome ground clamp in prior art easily to come off The defect that edge bar is picked up.

This utility model realizes by the following technical solutions: a kind of novel ground clamp, and including Gripper body, described chuck is originally Body is provided with the fixing end of left elastic clip, right elastic clip, action bars joint and ground wire, also includes U-shaped block piece, described U-shaped The opening of block piece is hinged on Gripper body, and the U-shaped block piece other end is enclosed within Gripper body opening part, on the fixing end of described ground wire It is fixed with the ground connection that one end tilts.

Described U-shaped block piece Guan Bi end is provided with lock-screw.

Compared with prior art, the beneficial effects of the utility model are: this utility model can effectively prevent wire from ground clamp Come off, when wire comes off in elastic clip, U-shaped block piece can stop coming off of wire further, it is to avoid comes off and causes Potential safety hazard；This utility model ground wire is fixed end and is provided with the ground connection of tilting, can pick up operation with insulating bar easily Knock-off joint.

In figure: 1, Gripper body；2, left elastic clip；3, right elastic clip；4, lock-screw；5, U-shaped block piece；6、 Action bars joint；7, ground connection；8, the fixing end of ground wire.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, a kind of novel ground clamp, including Gripper body 1, described Gripper body 1 is provided with left elastic clip End 8 fixed by sheet 2, right elastic clip 3, action bars joint 6 and ground wire, and left elastic clip 2, right elastic clip 3 are used for clamping Wire, action bars joint 6 is for attended operation bar, and this utility model includes U-shaped block piece 5, the opening of described U-shaped block piece 5 End is hinged on Gripper body 1, and U-shaped block piece 5 other end can be enclosed within Gripper body 1 opening part, and end 8 fixed by described ground wire On be fixed with one end tilt ground connection 7, ground connection 7 is used for connecting ground wire, due to exist tilt ground wire connect Part 7, therefore can pick up action bars joint 6 with insulating bar very easily.

Described U-shaped block piece 5 closes end and is provided with lock-screw 4, by pretension lock-screw 4, strengthens fixing U-shaped block piece further 5, or need not lock-screw 4, only fix U-shaped block piece 5 by the compression fit of U-shaped block piece 5 with Gripper body 1.

Claims

1. a novel ground clamp, including Gripper body (1), described Gripper body (1) be provided with left elastic clip (2), The fixing end (8) of right elastic clip (3), action bars joint (6) and ground wire, it is characterised in that: also include U-shaped block piece (5), The opening of described U-shaped block piece (5) is hinged on Gripper body (1), and U-shaped block piece (5) other end is enclosed within Gripper body (1) opening part, the fixing end (8) of described ground wire is fixed with the ground connection (7) that one end tilts.

Novel ground clamp the most according to claim 1, it is characterised in that: the Guan Bi end of described U-shaped block piece (5) is provided with Lock-screw (4).
