The utility model is composed of a forged tension-proof casing and an insulated oblique wedge sleeve assembly. A wire-pulling ring is arranged at the lower side of the tension-proof casing, a plurality of annular rib plates are arranged at the periphery of the tension-proof wire clip, a conical through hole is arranged at the center of the tension-proof casing, a cutting groove is arranged at the upper side of the tension-proof casing, and both sides of the cutting groove are respectively extended to a hanging lug. The oblique wedge sleeve assembly comprises two halves of conical sleeves, and the center of the oblique wedge sleeve assembly is provided with a thread groove; a wire-clipping seat is arranged at the tail end of one conical sleeve, so a cover plate and a towed wire can be fixedly locked at the wire-clipping seat by a U-shaped bolt; then, one conical sleeve and other conical sleeve are simultaneously inserted in the conical through hole of the tension-proof casing, and the tension-proof casing is hung on an electric tower. When the utility model is adopted, the wire can be simply assembled, and the wire can be tightly clipped when the wire is pulled and swinged.
Description
The utility model relates to a kind of wire clamp, relates to a kind of insulation strain clamp of electric line or rather.
The spiral type strain clamp of traditional type is covered mutually by two cover plates and constitutes, at height in the air with the electric wire on electric tower traction to two cover plates, and again with-U-bolt runs through two cover plates and the solid electric wire lock that makes of spiral shell is set the position, electric wire can connect conducting between Liang Dianta.Because strain clamp must carry out the screw lock operation in the air at height, this wire clamp is very inconvenient when the traction electric wire is done assembling, be not suitable for operating in the air very much at height, and the electric wire after the traditional type strain clamp is fixing height meet with in the air wind rock or because of gravity sag after, easily cause the loosening of locking bolt, two cover plates can't clamp electric wire, cause the final slippage terminal clamp of electric wire, and the accident that electric wire breaks away from or opens circuit takes place.And the wire insulation skin after the locking also may excessively be compressed breakage, causes electric wire to get loose and will draw assembling again, takes time and effort and does not meet economic benefit.
The purpose of this utility model is the insulation strain clamp of a kind of electric line of design, makes electric wire pullled by external force to rock or conduct oneself with dignity more can clamp electric wire when sagging, and electric wire is got loose, and assemble simple and easy, long service life.
The purpose of this utility model is to realize like this, the insulation strain clamp of electric line, comprise strain insulator housing and wedge cover group, it is characterized in that: described strain insulator housing downside is provided with stay thimble, stay thimble combines with reinforced ribs, be arranged with the ring-type floor more than around the strain insulator housing, the centre of strain insulator housing is provided with conical through-hole and is through to strain insulator housing two ends, and strain insulator housing upside offers grooving; Described wedge cover group includes two taper sheath, U-bolt and cover plates that respectively are semicircle shape, the centre of described two taper sheaths respectively is provided with semicircle groove, one end of one taper sheath is provided with tension seat and inwardly is provided with two and holds piece, described U-bolt passes the tension seat of a cover plate and a taper sheath, the taper sheath of two semicircle shapes is combined in the conical through-hole that is plugged on described strain insulator housing, and two on the taper sheath holds the not end that piece is limited to another taper sheath.
Each oblique being extended with of both sides in the grooving of described strain insulator housing upside for the hangers that hangs the insulation strain clamp.
Described strain insulator housing also includes collets, buries underground and solid conical through-hole one end at described strain insulator housing of spiral shell; Described collets are arc, and an end has flange, and the other end is the oblique angle piece.
Each extension of one side of described wedge-shaped sleeve group two semicircle shape taper sheaths is provided with the stripe shape barricade, and two bar shaped barricades are arranged in the grooving of described strain insulator housing upside.
Described wedge cover is organized in the semicircle groove of two semicircle shape taper sheaths and respectively is provided with the ring shaped thread face.
Two semicircle shape taper sheaths of described wedge cover group are made by insulating material.
Described insulating material is an industrial plastic.
The collets of described strain insulator housing are made with industrial plastic.
The insulation strain clamp of the utility model electric line, its strain insulator housing is processed to form through forging, the hangers of its each oblique extension of grooving both sides can be for being hung on the porcelain insulator, the wedge cover group of insulation then is set in the conical through-hole of strain insulator housing, two respectively are the interior semicircle groove flank clamping electric wire of insulation taper sheath of semicircle, the bar shaped barricade that each extension of two taper sheaths upper end is provided with can make wedge cover group do limited revolution in the strain insulator housing, because an end of a taper sheath is provided with tension seat, can insulation cover plate be locked on the tension seat for U-bolt.During use, when wire grip catch on the strain insulator housing and with electric wire traction to electric tower place, it is the loose portion that available two taper sheath clamping electric wires are not held, cooperate cover plate to make electric wire be locked in the tension seat place with U-bolt again, behind the grooving of electric wire pile warp strain insulator housing, two taper sheaths are cooperated simultaneously the conical through-hole that inserts the strain insulator housing, make taper sheath in the conical through-hole of strain insulator housing, produce clamping force closely, design by ring-type floor around the strain insulator housing, can bear the outer tension force after two taper sheaths cooperate clamping, electric wire is rocked by wind more to pull, two taper sheaths more clamp on the contrary, make the electric wire can be, and have the characteristics of the simple and easy and long service life of assembling because of external force effect slippage does not go out strain clamp.
The insulation strain clamp of the utility model electric line, its wedge cover group is made with insulating material, after electric wire is pulled and is assembled on the strain clamp, its strain insulator housing does not contact with electric wire, therefore unregulated power exists on the strain insulator housing, electric power will not be transmitted on the electric tower, guarantee fail safe and convenient maintenance.
The insulation strain clamp of electric line of the present utility model, simple in structure, installation exercise and repair and maintenance are all very simple, can closely clamp electric wire, electric wire can not rocked or the sagging electric wire that causes of conducting oneself with dignity gets loose because of pullling of external force, closely clamp all the better, and its housing does not contact with electric wire, and practical function is arranged.
