The wiring fastening component comprises a pressing block and a screw rod, the screw rod of the wiring fastening component below the first wiring groove 3 penetrates into the first wiring groove 3 from bottom to top, the pressing block is arranged in the first wiring groove 3 in a threaded fit mode with the main body frame, the screw rod is arranged at the end portion of the screw rod, the pressing block can be driven to move up and down through the rotating screw rod, and the pressing block can be driven to compress an electric wire in the first wiring groove 3 together with the main body frame.

The screw rod of the wiring fastening component of 4 sides in second wiring groove then the level sets up to transversely penetrate second wiring groove 4, with main body frame screw-thread fit, its briquetting sets up in second wiring groove 4, can drive this briquetting lateral shifting through rotatory screw rod, can order about the briquetting and compress tightly the drainage wire in second wiring groove 4 together with main body frame.

When carrying out the drainage wiring through above-mentioned fastener, at first with the drainage wire from supreme second wiring groove 4 of penetrating down to through rather than the fixed locking of the wiring fastening components who corresponds, then through the above-mentioned wiring fastener of stock mounting tool centre gripping, the electric wire can enter into first wiring groove 3 in through opening 31, thereby hang above-mentioned fastener and establish on the electric wire, then screw up the wiring fastening components of first wiring groove 3 below through the stock spanner, with the fixed locking of electric wire, thereby realize the drainage wiring.

Scheme more than adopting, because the drainage wire is from supreme stretching into the second wiring groove and fixed down, avoid drainage wire bending deformation, current structure relatively has lacked because of the elastic torsion that bending deformation produced when lifting the wiring, consequently makes the operation light laborsaving more.

As shown in fig. 1, the end of the opening 31 is provided with a guide portion 32 for guiding the electric wire into the first wire connecting groove 3, the guide portion 32 is provided at the upper end of the opening 31 and is inclined upward to the right, and when the wire clamp is clamped by a pole installation tool, the electric wire can be accurately inserted into the first wire connecting groove 3 through the opening 31 by the guiding action of the guide portion 32.

Of course, the guide portion 32 may be disposed horizontally and extend to the right, or may be disposed at the lower end of the opening 31, and the main purpose is to extend the opening end portion and enlarge the opening, thereby further facilitating the operation.

As shown in fig. 1-2, the wire connection fastening assembly cooperating with the second wire connection slot 4 is arranged on the front side of the second wire connection slot 4, but may be arranged on the rear side, and the left side of the second wire connection slot 4 is provided with a connecting portion 41 which can cooperate with an installation tool.

The connecting portion 41 is a boss structure which is arranged on the left side wall of the second wiring groove 4 and protrudes from the upper end and the lower end, and is convenient to cooperate with an installation tool to perform wiring installation operation.

As shown in fig. 3-6, the wire connecting and fastening assembly of the wire clamp comprises a screw rod 1 and a pressing block 2, wherein the pressing block 2 is arranged at the upper end of the screw rod 1.

The screw rod 1 comprises a threaded rod 11, an operation portion 12 is arranged at the lower end of the threaded rod 11, a connecting column 13 is arranged at the center of the upper end of the threaded rod, a limiting boss 14 is arranged at the center of the upper end of the connecting column 13, and the limiting boss 14 and the connecting column 13 form a T-shaped connecting portion.

The operating portion 12 may be a regular hexagonal operating rod, and the connecting column 13 and the limiting boss 14 are both cylindrical structures.

A first groove 21 is formed in the pressing block 2, a second groove 22 is formed in an opening in the lower portion of the first groove 21, the first groove 21 and the second groove 22 form a T-shaped groove matched with the T-shaped connecting portion, and movable grooves 23 are correspondingly formed in side walls of two sides of the second groove 22.

Wherein, first groove 21 and second groove 22 are located 2 below middle part positions of briquetting, activity groove 23 corresponds and sets up at 2 bottom centers of briquetting, is the arc structure that uses the bottom center as the centre of a circle, and when screw rod 1 was connected with the cooperation of briquetting 2, screw rod 1 can be located the bottom central point of briquetting 2 and put, and when the wiring, the atress was steady, and the laborsaving and effectual fastening to the electric wire of operation.

The diameter of spacing boss 14 is greater than the diameter of activity groove 23 and is less than the width of first groove 21, spliced pole 13 and the width that activity groove 23 looks adaptation and diameter are greater than second groove 22, during the installation, the T type connecting portion of screw rod 1 transversely insert the T type inslot of briquetting 2 until spliced pole 13 enters into activity groove 23 in to can' T deviate from in activity groove 23 by the restriction, and guarantee spliced pole 13 can be in the activity of peripheral rotation in activity groove 23.

In order to facilitate installation and reliable limiting after installation, the width of the second groove 22 is slightly smaller than the diameter of the connecting column 13, and during installation, the second groove can be forcibly pressed on the screw rod 1 by external force in a cold pressing mode, and can also be sleeved on the screw rod 1 by heating the pressing block 2 to expand after being heated in a hot installation mode.

Adopt above-mentioned scheme, the processing equipment of briquetting 2 and screw rod 1 is all very convenient, and screw rod 1 transversely inserts the T type inslot of briquetting 2 through T type connecting portion simultaneously to deviate from easily, can do big with spacing boss 14's size moreover to guarantee axial direction's spacing effect, overall structure is more reliable and more stable, and life is high.

In addition, the upper end of the pressing block 2 is provided with a contact surface 24 which is concave downwards, so that the electric wires can be better matched, and the contact surface 24 is provided with a tooth-shaped structure, so that the fastening and connecting effects are better.
