Abstract
The utility model discloses an elastic joint for ground connection used connecting ground when communicating high voltage lines. An insulating rod used for operation is connected with a bare copper line used for ground connection through a line clamp. The line clamp can be composed of two clamping plates connected through a connector wound with a spring, or can be a supporting base provided with a plurality of elastic elements. The upper end of the line clamp is in a V shape. The middle of the line champ is provided with one or a plurality of round holes in different sizes for clamping a conducting line. When using, a user can only push the line clamp toward the conducting wire, and then the conducting wire is clamped in the line champ. Thus, the ground connection is realized. The utility model has the advantages of flexible operation and high safety. The elastic joint for ground connection can be used for clamping conducting wires or conducting bodies in different sizes and shapes in different occasions.
Description
The utility model relates to the high-tension line power tool, earthy elasticity ground joint during particularly about high-tension line power failure operation.
When carrying out the high-tension line interruption maintenance, must can work behind the hanging earthing conductor earlier through electrical verification, generally be to adopt the action bars earthing.It is by on the insulating bar with the joint that is threaded, connect an earthy bare copper wire on the joint.Operating personnel's hand-held bar during use, joint is inserted lead, rotate insulating bar then, until making joint compress lead, reach the ground connection purpose, though this method is the clamping lead reliably, but troublesome poeration, painstakingly, very inconvenient, thereby in real work, usually adopt and throw the extension method, an end that is about to earthy bare copper wire is directly thrown to lead, though this maneuver is simple, but do not meet the requirement of electric power safety operational procedure, meet wind-force or lead accident situation such as with trembling, can make bare copper wire break away from lead, cause the accident of human electric shock.
Elasticity ground joint of the present utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of flexible and convenient operation to be provided, safe and reliable ground joint.
The elasticity ground joint that the utility model provides, be on insulating bar, to connect a binding clip that has flexible member, binding clip is assembled by holding frame and flexible member, binding clip can be formed by connecting by the connector that is wound with torsion spring with two plate holder plates, also bearing that one group of above flexible member is housed, for making binding clip clamping lead easily, the top of binding clip is one " V " font, there is the hole, garden with the spring controlled clamping connection lead that differs in size more than the centre, lead that can the clamping different-diameter also has the fixed earthy bare copper wire of connector on the binding clip.Holding frame on the wire clamp can be made with aluminium, copper or lightweights such as aluminium alloy, steel alloy, material that anti-wear performance is good.The hand-held insulating bar of operating personnel is aimed at lead with " V " shape mouth of binding clip and one is pushed away gently during use, and binding clip promptly under the effect of flexible member, snaps in lead in the binding clip, is grounded.Insulating bar can require to regulate length with the workplace.
This elasticity ground joint also can be used for other occasions, and clamping differ in size different lead or conductor are grounded purpose.
The elasticity ground joint that the utility model provides is compared with the screw-type ground joint, and advantage is significantly, and it is simple in structure, and volume is little, and is in light weight, operates very flexiblely, and safe and reliable, can stop the accident of human electric shock of taking place owing to ground connection is improper.
Fig. 1 has described an embodiment of the present utility model.
Fig. 2 has described another embodiment of the present utility model.
Elasticity ground joint as shown in Figure 1, on insulating bar with screw (2) or similarly other connectors connect binding clips (5), binding clip (5) is connected by a screw (8) that is wound with torsion spring (7) by two clamping plates (6), for making binding clip energy clamping different-diameter, the inboard of different lead two clamping plate (6) has two cambered surfaces that vary in size (a), inboard upper end is an inclined-plane, the binding clip upper end that is assembled is V-shaped, and the centre is two holes, garden that differ in size using in order to the clamping lead.Insulating bar (1) and spiral shell copper cash (3) are cemented in wherein on the clamping plate (6) by screw (2,4) respectively.Clamping plate (6) are made with aluminium alloy.During use, operating personnel hand insulating bar (1) aligning lead one and push away, and under the effect of torsion spring (7), lead promptly by " V " shape mouth, is snapped in the hole, garden between two clamping plate (6).Be grounded.
Elasticity ground joint as shown in Figure 2, the binding clip that connects insulating bar (1) and bare copper wire (3), be to be assembled by a bearing (9) and one folder spring (12) and one group of arch spring (13), folder spring (12) is processed by a reed, insert respectively in the chute (10) on the bearing (9) at two ends, be " V " font, the middle hole, garden that forms a clamping lead, a screw (14) will press from both sides spring (12) and be fixed on the bearing (9), the assembling of one group of arch spring (13) symmetry, insert the chute (10 of bearing (9) respectively, 11) in, its apsis withstands the b point of folder spring (12).Situation about using is identical with embodiment one.
Claims (6)
1, a kind of elasticity ground joint, an insulating bar (1) and earthy bare copper wire (3) are arranged, it is characterized in that: insulating bar (1) is gone up with screw (2) or similar connector and is connected a binding clip (5), binding clip (5) is assembled by holding frame and flexible member, the upper end of binding clip (5) is V-shaped, the hole, garden that the centre has one or more clamping leads that differ in size to use.
