Description
Technical field
What a kind of strain clamp for large-section lead of the utility model related to is crimping, the fixture of a kind of heavy in section steel reinforced aluminium conductor.
Background technology
The strain clamp of present domestic transmission line, it makes the type mode two kinds: the one, the bending-type strain clamp is about to aluminum pipe bending, boring making strain insulator body, and the 2nd, the solder type strain clamp is about to drainage plate and Al pipe butt welding and makes the strain insulator body.Above-mentioned various strain clamp all has drawback, the bending-type strain clamp reduces at the bending part contact-making surface, and boring back water inlet easily, crimping steel anchor position gets rusty easily, the solder type strain clamp is less at the welding position contact-making surface, form electric weak link in the conduction transmission course, the welding position generates heat easily, influences the line security operation.
Summary of the invention
The utility model purpose is to provide a kind of strain clamp for large-section lead at above-mentioned weak point, it is the strain clamp that a kind of large-section lead is used, electric conductivity is good, the large-section lead strain clamp changes original common bending-type strain clamp and likes water inlet and the little defective of solder type strain clamp welding position contact area easily, adopt the connected mode of taper surface contact, increase contact area, thereby guarantee the operation of circuit long-term safety.
The large-section lead strain clamp is to take following scheme to realize: the large-section lead strain clamp comprises crimping aluminum pipe, drainage plate, drainage wire clamp and crimping steel anchor, the crimping aluminum pipe is provided with the conical surface, drainage plate top is provided with the taper hole cover, the drainage plate bottom is provided with two plates, the taper hole that drainage plate top is provided with is sleeved on the conical surface of crimping aluminum pipe, and is fixedly connected.Two plates of drainage plate bottom are provided with two plate through holes; Drainage thread is folded with veneer, and veneer is provided with the veneer through hole, and drainage wire clamp veneer is through in the two plates of drainage plate and is bolted to connection.The drainage wire clamp is provided with the conductor compression jointing hole.The crimping aluminum pipe is provided with hollow hole, and crimping steel anchor pierces into that crimping connects in the hollow hole that the crimping aluminum pipe is provided with.Crimping steel anchor is provided with endoporus, is used for crimping lead steel core.
Large-section lead strain clamp crimping steel anchor is connected with the crimping of lead steel core, and the crimping aluminum pipe is connected with conductor compression jointing, bears pulling force and the effect of lead current-carrying.The drainage wire clamp is connected with conductor compression jointing, and drainage wire clamp and crimping aluminum pipe are bolted to connection, and bear the current-carrying effect.
Reasonable in design, the compact conformation of a kind of strain clamp for large-section lead, safe and convenient to use.Because the utility model heavy in section strain clamp crimping aluminum pipe is provided with the conical surface and drainage plate is provided with taper hole, connected mode was that face contacts with face when the crimping aluminum pipe was connected with drainage plate, increase contact area, the crimping aluminum pipe adopts tapering to be connected with drainage plate, does not need welding fixing, drainage plate adopts two plate modes, the drainage wire clamp adopts veneer, and drainage plate adopts two plate order crab bolts to be connected with the drainage wire clamp, increases contact-making surface, guarantee the electric property of strain clamp, thereby guaranteed the line security operation.The large-section lead strain clamp changes original common bending-type strain clamp and likes water inlet and the little defective of solder type strain clamp welding position contact area easily, adopts the connected mode of taper surface contact, increases contact area, thereby guarantees the operation of circuit long-term safety.
