Abstract
The utility model relates to a novel wedge type tension bearable wire clamp, which belongs to the field of electrical power hardware fittings. The wedge type tension bearable wire clamp of the utility model consists of a wire clamp body, a straight wedge, a bend wedge, a press board, a hung board and an S-shaped connection bolt. The wire clamp body, the straight wedge, the bend wedge are evenly divided into two half body, the straight wedge and the bend wedge extend into the wire clamp body, the press board fixes the straight wedge and the bend wedge, the hung board plays an part in connecting the connection wire clamp and the unbearable opening string, the S-shaped connection bolt fixes the wire clamp body. When in installation, a conductor is not needed to be cut, which is in a series state through the novel wedge type unbearable opening wire clamp, no electric contact point is arranged on the conductor, thus improving reliability of the circuit run, the novel wedge type holding way and the wire clamp whole structure character, after using some time of the conductor, make the wire clamp not loosen but with a trend more and more tight.
Description
Technical field
The utility model relates to the electric armour clamp field, especially is applicable to the novel wedge type strain clamp in the power transmission sequence lead.
Background technology
The strain clamp of power transmission sequence lead (steel reinforced aluminium conductor, aluminium alloy stranded conductor etc.) can be divided at present: screw bolt-type, compression-type, preformed armor rods type and novel wedge type.Screw bolt-type and preformed armor rods type generally are used for, the lead of small bore, for heavy in section (400mm
2And with upper conductor) then adopt compression-type.Only be used for the steel strand wire of overhead ground wire about novel wedge type strain clamp in China, can be used for the novel wedge type strain clamp of larger cross-section lead, not only do not produce at home, also do not use.For the compression-type strain clamp, the convenient inadequately special hydraulic means that needs is installed, the not reproducible use in back is installed, and has electric contact point, increased the insecurity of circuit operation.
Summary of the invention
The purpose of this utility model provides a kind of novel wedge type strain clamp that can be used for cutting more greatly lead.
The purpose of this utility model realizes as follows: novel wedge type strain clamp described in the utility model is made up of wire clip body, straight wedge, curved wedge, pressing plate, link plate and S shape connecting bolt.Straight wedge and two kinds of structures of curved wedge are divided into two halfbodies, are fixed on earlier and put into wire clip body (shell) on the lead then; Outer surface at wedge scribbles solid lubricant coating, promptly makes things convenient for wire clamp to install; Simultaneously in the circuit running, for wire clamp provides the suitable lubricated and buffering of motion, with the lead that guarantees wire clamp safety.
Wherein wire clip body (shell) is an aluminum alloy material, and two halfbodies about being divided into are installed on the chock outside, have auto-lock function, convenient disassembly; Chock is an aluminum alloy material, and chock adopts non-circular protection, and promptly inner chamber is an ellipsoidal structure, provides excellent protection for lead when holding lead reliably; S shape connecting bolt connects chock and lead, and chock is fixed on the lead; Link plate is steel/hot galvanizing material, and whole device is connected on iron tower or the shaft tower; Wire clip body (shell) casting forms, and is used to lock whole device, and for whole device with stress point (being the hanging point of link plate) is provided being connected of shaft tower.
Good effect of the present utility model is as follows: do not need wire cutting during installation, lead is by novel wedge type strain clamp with continuum of states, there is not any electric contact point on the lead, improved the operational reliability of circuit, the method of clamping of novel wedge type, and the total feature of wire clamp, making lead after date when using a section, wire clamp can not become flexible face and the trend of drawing tighter and tighter is arranged; It is convenient to install, and does not need special tool(s) (as hydraulic press etc.), makes installation efficient improve greatly; Can allow behind the retighten lead row to install, also be simple and easy and make things convenient for when needing dismounting again.
