Abstract
The invention discloses a quick self-locking aluminum alloy strain wire clamp and solves the problem of easiness in dropping-off of a wire in the using process of the conventional wire clamp. The quick self-locking aluminum alloy strain wire clamp adopts the structure that: curved clamping pieces are arranged in a conical pipe body; a pipe plug is arranged at the end of the conical pipe body; a U-shaped bolt is connected with the conical pipe body through a pulling plate; the curved clamping pieces are divided into an upper piece and a lower piece; the two curved clamping pieces are combined into a piece of which the outer circumference is a conical body in fit with an inner wall of the conical pipe body; and the quick self-locking aluminum alloy strain wire clamp also comprises a fixed type or inserting-pulling type pre-tightening thrust pipe which is used for fastening a conductor. By adopting the fixed type or inserting-pulling type pre-tightening thrust pipe, the conductor and the wire clamp are fastened together, so that the problem of dropping-off of the conductor is solved. By making internal surfaces of the curved clamping pieces into curved surfaces and forming convex ribs at equal intervals in the longitudinal overall length direction of the internal surfaces, the conductor is easy to enter and difficult to exit, so that the aim of locking the conductor is fulfilled.
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 up 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 realizes through following technical proposals: fast self-locking aluminium alloy strain clamp; Comprise conical tube, curve folder, pipe plug, U-bolt; The curve folder is installed in conical tube, and the end of conical tube is provided with pipe plug, and U-bolt is connected with conical tube through 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 on the vertical total length direction of inner surface, is provided with equally spaced fin.
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, the equidistance fin is arranged; Make lead in certain weight range, occur bending and deformation, the mechanical performance of lead is changed, increased the frictional resistance that lead is extracted out simultaneously again; Difficulty goes out to make lead be prone to into, thereby reaches 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.That the present invention has is in light weight, intensity is high, less energy consumption, advantage quick for installation.
