Line, not only illegal safety code, and being constituted a threat to the life of staff.And the ground wire used at present can not put in electricity
It is connected in cable elbow arm set with " conductor ", therefore develops a kind of extremely important for Special grounding wire in cable distribution box elbow arm set.
The purpose of this utility model is the life security and equipment dependability for ensureing repair personnel, improves operating efficiency, contracting
The short repairing activity duration, reduce customer complaint rate.
Utility model content
There is provided special in a kind of cable distribution box elbow arm set for above-mentioned problems of the prior art for the utility model
Ground wire, solves the problem of cable run power failure operation time is long in the prior art.
The technical solution of the utility model is as follows：
Cable distribution box elbow arm set in Special grounding wire, including upper jaw, lower jaw, spring, insulating bar, phase sequence handle and
It is grounded annealed copper wire；Upper jaw and lower jaw are connected by rotating shaft open-close type, the openend occlusion of upper jaw and lower jaw, upper jaw
Spring is set between lower jaw afterbody, and the connection end of upper jaw and lower jaw connects insulating bar respectively, and the afterbody of insulating bar connects
Connect phase sequence handle；Described upper jaw connection ground connection annealed copper wire.
The inside of described upper jaw sets upper translot and upper straight trough, and upper translot and upper straight trough right-angled intersection are set；It is described
Lower jaw it is corresponding with upper jaw be provided with lower translot and lower straight trough, lower translot and lower straight trough right-angled intersection are set.
Described upper translot and lower translot constitute translot through hole.
Described upper straight trough and lower straight trough constitute straight trough hole.
Described upper jaw is connected by bolt with ground connection annealed copper wire.
Described phase sequence handle outer surface is coated with different colours phase sequence guide coat.
The utility model has the advantages of as follows：
1st, the utility model solves the problem for covering Special grounding without cable distribution box elbow arm on the market.
2nd, cost is low, easy to use, is connected by open-close type, only needs one to pinch, a pine can be grounded.
3rd, joint use way, by setting straight trough and translot, can be clipped in end and pvs (pole-mounted vacuum switch) electric discharge ground connection,
Busbar or busbar junction electric discharge ground connection can be clipped in, can also clamp to discharge at wire and insulated conductor electricity testing grounding ring and connect
Ground.
4th, phase sequence differentiation can be carried out by phase sequence handle, it is to avoid because not remembeing phase sequence wrong circuit after construction, and make
Into user's motor reversal.
5th, shorten repairing the activity duration, solve the cable run power failure operation time it is long the problem of, reduce user throwing
Tell rate.

Embodiment
Embodiment
As illustrated, Special grounding wire in cable distribution box elbow arm set, including upper jaw 2, lower jaw 7, spring 4, insulation
Bar 5, phase sequence handle 6 and ground connection annealed copper wire 9；Upper jaw 2 and lower jaw 7 are connected by the open-close type of rotating shaft 8, upper jaw 2 and lower pincers
The openend occlusion of mouth 7, sets spring 4, one end of spring 4 passes through upper spring fixed column between upper jaw 2 and the afterbody of lower jaw 7
203 are connected with upper jaw 2, and the other end of spring 4 is connected by lower spring fixed column 703 with lower jaw 7；The connection of upper jaw 2
End connects insulating bar 5 by upper rivet hole 204, upper insulating bar fixed column 205, and the connection end of lower jaw 7 passes through lower rivet hole
704th, the lower connection of insulating bar fixed column 705 insulating bar 5, the afterbody connection phase sequence handle 6 of insulating bar 5, phase sequence handle outer surface is applied
