Description
Technical field
The utility model belongs to power equipment technical field, is specifically wedge-shaped earthing clamp.
Background technology
At present, when overhead insulation line line outage is overhauled, it is necessary to which mounting ground wire just can guarantee that the life of service personnel
Life safety.When using aerial bare line in the past, ground wire is directly hung on bare conductor, the purpose that can be grounded.It is but existing
After overhead insulation line is used instead, hanging earthing conductor is but into difficulty during interruption maintenance, it is necessary to manually outside the insulation of insulated electric conductor
Skin is splitted, then ground wire is hung up, and such operating process is than relatively hazardous.
Chinese patent CN2749068Y discloses a kind of thrusting earthing clamp, including upper plastic shell, lower plastic shell, connects
Contact knife piece and ground loop, upper plastic shell and lower plastic shell mutually fasten, and are compressed by screw bolt and nut, upper plastic shell
Main line clamping opening and ground loop connector are provided between lower plastic shell, ground loop, main line are connected with ground loop connector
Contact blade is provided with clamping opening.This kind of thrusting earthing clamp is used to mount ground on overhead insulation line with safe ready
Line.But this kind of thrusting earthing clamp main line clamping opening and the size of ground loop connector be it is fixed, can only be with special diameter
The compactness of conducting wire and ground wire is all preferable, and the conducting wire and ground wire if not special diameter can cause electric conductivity to be deteriorated.
Utility model content
The utility model in view of the shortcomings of the prior art, provide wedge-shaped earthing clamp, the wedge shape earthing clamp can with it is various
Various sizes of conducting wire and ground loop have preferable compactness, ensure the electric conductivity of wedge-shaped earthing clamp.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：Wedge-shaped earthing clamp,
Including upper clamping block, lower gripping block, screw rod and nut, the upper clamping block includes the first wedge block and opposite side of side
The first arc hook；Second arc of the second wedge block and opposite side that the lower gripping block includes side hooks；The screw rod
Fastened through the upper clamping block and the lower gripping block and with the nut, first wedge block is hooked with second arc
Conducting wire is matched for clamping tightly, first arc is hooked is matched for clamping tightly ground loop with second wedge block, is set in first wedge block
The first cavity is equipped with, the second cavity, first cavity and first wedge block are provided with second wedge block
Between form the first shrapnel, form the second shrapnel between second cavity and second wedge block.This kind wedge shape ground wire
Folder is when in use clamped upper clamping block and lower gripping block by nut, since the elasticity of the first shrapnel and the second shrapnel makes conducting wire
Increase with ground loop and the contact area of the first shrapnel and the second shrapnel, can be with various various sizes of conducting wires and ground loop all
There is preferable compactness, ensure the electric conductivity of wedge-shaped earthing clamp.
In above-mentioned technical proposal, it is preferred that first arc is hooked with scribbling conductive grease at the second wedge block cooperation.
Using the structure cause the first arc hook with the second wedge block and conducting wire electric conductivity it is more preferable.
In above-mentioned technical proposal, it is preferred that first wedge block hooks with second arc and scribbles conductive grease at cooperation.
Using the structure cause the first arc hook with second wedge block and ground loop electric conductivity it is more preferable.
The utility model compared with prior art, has the advantages that：This kind wedge shape earthing clamp leads to when in use
Cross nut to clamp upper clamping block and lower gripping block, since the elasticity of the first shrapnel and the second shrapnel makes conducting wire and ground loop and the
The contact area of one shrapnel and the second shrapnel increases, and can have preferable be bonded with various various sizes of conducting wires and ground loop
Degree, ensures the electric conductivity of wedge-shaped earthing clamp.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the structure diagram at collet in the utility model embodiment.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2,
Wedge-shaped earthing clamp, including upper clamping block 1, lower gripping block 2, screw rod 3 and nut 4, the upper clamping block 1 include the of side
First arc of one wedge block 11 and opposite side hooks 12；Second wedge block 21 of the lower gripping block 2 including side and another
Second arc of side hooks 22；The screw rod 3 is through the upper clamping block 1 and the lower gripping block 2 and tight with the nut 4
Gu first wedge block 11 hooks 22 with second arc and is matched for clamping tightly conducting wire 5, first arc hooks 12 and described second
Wedge block 21 is matched for clamping tightly ground loop 6, is provided with the first cavity 13 in first wedge block 1, in second wedge block 21
The second cavity 23 is provided with, forms the first shrapnel 14 between first cavity 13 and first wedge block 1, described
The second shrapnel 24 is formed between two cavitys 23 and second wedge block 21.This kind wedge shape earthing clamp passes through nut when in use
Upper clamping block and lower gripping block are clamped, since the elasticity of the first shrapnel and the second shrapnel makes conducting wire and ground loop and the first shrapnel
Increase with the contact area of the second shrapnel, there can be preferable compactness with various various sizes of conducting wires and ground loop, protect
The electric conductivity of the wedge-shaped earthing clamp of card.
First arc hooks 12 with scribbling conductive grease at 21 cooperation of the second wedge block.Cause first using the structure
Arc hook with the second wedge block and conducting wire electric conductivity it is more preferable.
First wedge block 11 hooks with second arc and scribbles conductive grease at 22 cooperations.Cause first using the structure
Arc hook with second wedge block and ground loop electric conductivity it is more preferable.
