Abstract
A rapid self-locking aluminum alloy strain clamp is provided to solve the problem that a wire easily sheds off during the process of using the prior clamp. A curve clamp piece is arranged inside a conical pipe body, the end part of the conical tube body is provided with a pipe plug, and a U-shaped bolt is connected with the conical pipe body through a pulling plate. The curve clamp piece is composed of an upper clamp piece and a lower clamp piece, the outer circumference of the two combined curve clamp pieces is a cone and is fitted with the inner wall of the conical pipe body, and a fixed type or plug-in preload thrust pipe used for fastening a conducting wire is also included. By adopting the fixed type or plug-in preload thrust pipe, the conducting wire is fastened with the clamp, and the problem of the dropping of the conducting wire is avoided. As the inner surface of the curve clamp piece is of a curved surface shape, and equidistant convex ribs are arranged on the vertical full length direction of the inner surface, thus the conducting wire easily enters and is not easily gone out, and the aim of locking the conducting wire tightly can be realized.
Description
Technical field
The invention relates to a kind of aluminium alloy strain clamp, belongs in the power industry, the wire erection strain insulator stringing terminal of defeated, distribution overhead power line.
Background technology
Existing strain clamp generally is made of conical tube, curve folder, U-bolt, and in the process of using, behind the installation electric wire, because tightness is poor, electric wire comes off easily.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of fast self-locking aluminium alloy strain clamp that can avoid electric wire to come off.
The purpose of the invention is achieved through the following technical solutions: fast self-locking aluminium alloy strain clamp, comprise conical tube, curve folder, pipe plug, U-bolt, the curve folder is installed in conical tube, the end of conical tube is provided with pipe plug, U-bolt is connected with conical tube by arm-tie, it is characterized in that: described curve folder also comprises a fixed pretension thrust tube or a plug-in pretension thrust tube that is used for secure wires for two up and down.
Described fixed pretension thrust tube is positioned at conical tube inside, between curve folder and the pipe plug.
Described plug-in pretension thrust tube one end passes pipe plug, and its end extends to outside the pipe plug.
The inner surface of curve folder is made curve form, and is provided with equally spaced fin on the vertical total length direction of inner surface.
The end of described U-bolt is provided with split pin.
The beneficial effect of the invention: said structure is adopted in the invention, can adopt fixed or plug-in pretension thrust tube, and lead and wire clamp are tightened together; Avoided the problem of wire dropping.The inner surface of curve folder is made curve form, and on the vertical total length direction of inner surface, equidistant fin is arranged, make lead in certain weight range, occur bending and deformation, the mechanical performance of lead is changed, increased simultaneously the frictional resistance that lead is extracted out again, make lead easily advance difficulty and go out, thereby reach the purpose of lead locking.Wherein, the material of conical tube, curve folder, pretension thrust tube, pipe plug is aluminium alloy, makes the weight saving of this kind strain clamp also to have good Corrosion Protection simultaneously.The utlity model has in light weight, intensity is high, less energy consumption, advantage quick for installation.
