Description
Technical Field
The invention relates to a wire clamp
Background
The strain clamp is a hardware tool used for fixing a lead to bear the tension of the lead and hanging the lead on a strain insulator-string group or a tower, and can be divided into two types according to different structures and installation conditions, wherein the strain clamp is divided into a first type, the strain clamp is used for bearing all the tension of the lead or the lightning conductor, the clamp holding force is not less than 90 of the rated tension of the installed lead or the lightning conductor but not used as a conductive body, the strain clamp can be detached and used for other purposes after the lead is installed, the strain clamp comprises a bolt type strain clamp, a wedge type strain clamp and the like, the strain clamp is used as a conductive body besides bearing all the tension of the lead or the lightning conductor, and therefore once the strain clamp is installed, the strain clamp can not be detached any more and is also called as a dead clamp.
The tension-resistant wire clamp commonly used at present has certain difficulty in installation, is not easy to detach, has poor waterproof and insulating properties in rainy days, easily causes power leakage, and has certain danger.
Disclosure of Invention
The invention aims to provide a strain clamp which is convenient to mount and dismount, good in rain-proof and water-proof insulating performance and high in safety.
The above object of the present invention is achieved by the following scheme:
a wire clamp comprises two wedge-shaped shells, wherein plastic cores are arranged in the two shells, the two plastic cores are combined to form accommodating grooves for accommodating wires, different plastic cores form accommodating grooves with different sizes, the size of each accommodating groove is matched with that of each wire, a shell screw hole is formed in the end part of each shell, a first bolt penetrates through the screw hole and is connected to a hanging plate, the hanging plate is fixed through a second bolt, and the two wedge-shaped shells are fixed through buckles;
the method is characterized in that: the first bolt is coated with fastening glue, a limiting groove is formed in the matching surface of one plastic core, a limiting block is arranged on the matching surface of the other plastic core, and the limiting block is in interference fit with the limiting groove.
Further, the surface of the plastic core for the stroke accommodation groove is provided with a thread groove.
Furthermore, reinforcing ribs are uniformly distributed on the outer surfaces of the two wedge-shaped shells.
Furthermore, both ends of the plastic core are provided with protruding parts, and the protruding parts are tightly clamped with the end parts of the shell.
Furthermore, a sealing groove is formed in the side face of the boss, and the end of the shell is clamped into the sealing groove.
Furthermore, the coating of fastening glue is in the nut below of first bolt, when realizing waterproof, avoids hindering the dismantlement of first bolt.
Furthermore, the fastening glue is room temperature curing epoxy resin, and the plastic core is made of silica gel.
The technical effects of the scheme of the invention can be achieved as follows:
when the wire clamp is used for mounting the wedge-shaped shell, the first bolt is coated with the fastening glue, and the fastening glue prevents rainwater from corroding and entering the accommodating groove; meanwhile, the end part of the plastic core is provided with a convex part which is clamped and sealed with the shell, so that the erosion of rainwater is effectively prevented.
