Abstract
The utility model relates to a strain clamp comprising a pipe body. The rear end of the pipe body is provided with a steel anchor; the pipe body is further provided with a draining plate which is provided with a wire chase, and the wire chase has a downward opening. Two side contact of the draining plate with a conductor results in large contact area, small contact resistance, high conductivity and small loss during electric energy transmission; the mechanical strength of the draining plate is enhanced so that the draining plate is not easily fractured due to overlarge stress during use and the service life of the draining plate is prolonged; and the connecting strength between the draining plate and the conductor is improved, the requirements for materials and dimensions of connecting bolts are lowered, so that the installation reliability is improved, and the installation cost is reduced.
Description
Technical field
The utility model relates to a kind of wire clamp, relates in particular to a kind of strain clamp that is used for the strain insulator iron tower.
Background technology
Strain clamp is used for twisted wire is fixed on the strain insulator string of strain insulator shaft tower; Play the anchoring effect; Be in the ultra-high-tension power transmission line with the supporting important gold utensil of large-section lead; It is except the whole pulling force that bear lead, and still full electric conductor saidly must guarantee that strain clamp has on the basis of enough mechanical strengths and has good electric property.
Strain clamp commonly used is made up of body, drainage plate, drainage wire clamp and steel anchor etc.; Modal hydraulic strain clamp partly is connected on the steel anchor through the steel core of crimping with lead; Aluminum steel is connected on the aluminum pipe; Aluminum pipe is connected with the steel anchor, and the lead that transition is used is electrically connected through drainage plate and aluminum pipe.
This traditional strain clamp is as shown in Figure 1; Drainage plate generally is that single face is connected with lead; An end that is drainage plate is processed tabular, and the termination of lead also is pressed into tabular, passes through bolt then with drainage plate and lead fixed; Drainage plate and poor wire connection take place or cause overheated phenomenon because of contact-making surface is too little in this kind connected mode often, and security reliability is poor.
The utility model content
The utility model provides the strain clamp that a kind of security reliability is high, electric energy loss is few for solving the prior art problem.
The technical scheme of the utility model is: a kind of strain clamp, comprise body, and the rear end of said body is provided with the steel anchor, and said body also is provided with drainage plate, and this drainage plate is provided with wire casing, and Open Side Down for said wire casing.
The termination of lead is formed tabular through the compacting back; Insert wire casing, make two inner surfaces in two surfaces and wire casings of lead termination fully contact, improved the area of contact greatly; Effectively reduce contact resistance, make electric energy in transmission course, reduce loss; Simultaneously, the mounting means of the utility model can reduce lead and the drainage plate shearing force to connector greatly, has improved the intensity that connects, and has reduced the requirement to connector material, size, has reduced installation cost.
As preferably, be provided with the drainage wire clamp in the said wire casing, said drainage wire clamp is fixedly connected with said drainage plate.
As preferably, be provided with bolt hole on said drainage plate and the drainage wire clamp, said drainage plate and drainage wire clamp interfix through bolt.
As preferably, said drainage wire clamp comprises wire connecting portion and the fixed head that is mutually permanently connected, and the angle between the central axis of said wire connecting portion and the central axis of said fixed head is 10 ~ 30 degree.
As preferably, said drainage plate is connected on the said body through anchor ear, and drainage plate and said body are electrically connected.
As preferably, the inner surface of said anchor ear is provided with anti-slip tank.
In sum, the utlity model has following advantage:
1, drainage plate contacts with the lead two sides, and contact area is big, and contact resistance is little, and electric conductivity is strong, and loss is little in the electric energy transmitting process;
2, strengthened the mechanical strength of drainage plate, in use drainage plate is difficult for having prolonged the useful life of drainage plate because of stressed excessive the fracture;
3, improved the bonding strength of drainage plate and lead, reduced, improved the reliability of installing, reduced installation cost connecting material, dimensional requirement with bolt.
