Abstract

The utility model discloses a crimping type jump wire drainage fitting, comprising a T-shaped crimping tube, a drawer and a drainage clamp wire. The upper end of the T-shaped crimping tube is provided with a fan-ring-shaped clamping ring two end surfaces of which are provided with slide grooves; the lower end of the T-shaped crimping tube is a drainage plate which is connected to the drainage wire clamp; the section of the drawer is fan-ring-shaped; the lower ends of the left side surface and the right side surface of the drawers are provided with extending planes; and the drawer is connected to the T-shaped crimping tube through the cooperation of the extending planes and the slide grooves. The structure of the crimping type jump wire drainage fitting is simple, and the groove structure of the drawer can prevent drawer from concaving when the crimping connection is performed and can prevent the drawer from popping out when the drawer is in tension. In the meantime, the fan angle of the fan-ring-shaped clamping ring is over 180 degrees, which is convenient to install after the wire is built on the stilt, has a good force condition, electric performance and mechanical performance. Through the combination use with the strain clamp without the drainage plate and the drainage wire clamp, casting line and hanging line can be directly performed through the tackle, which simplifies the construction process and reduces waste of materials.

Description

A crimping type jumper drainage fitting

technical field

The utility model relates to a wire jumper drainage fitting for wire construction and transmission lines, in particular to a crimping wire jumper drainage fitting which plays the role of connection and overcurrent between a main wire and a drainage wire.

Background technique

In the traditional drawing and setting out construction of overhead wires, the tension wire clamp has a drain plate and a draining wire clamp, and the pulley cannot slide directly through it, so a special pulling head or a wire mesh sleeve must be used to pull the wire. After reaching the end of the tension section, cut off the traction head or a section of wire, and then crimp the tension clamp and the main wire in the air and then hang the wire, which will not only cause the loss of the traction head or net sleeve and wire, but also the installation of the drainage clamp Position and orientation are not adjustable.

Utility model content

Aiming at the defects in the prior art, the utility model provides a crimping type jumper drainage fitting, which can simplify the construction procedure and reduce the construction cost.

The specific technical solution is: a crimping type jumper drainage fitting, including a T-shaped crimping tube, a drawer and a drainage clip. Slot, the lower end of the T-shaped crimping tube is a drainage plate, and the drainage plate is connected with the drainage clamp; the cross section of the drawer is fan-shaped, and the lower ends of the left and right sides of the drawer are provided with extension items. type crimp connection.

The angle of the sector where the sector-shaped snap ring is located is greater than 180°.

The drainage plate and the drainage clamp are bolted or crimped.

After the drawer and the fan-shaped snap ring are connected, the cross section of the combined body is a complete circular ring.

The utility model has a simple structure, and the groove structure of the drawer can prevent the drawer from being concave when crimped and connected and from being raised when the drawer is under tension. It is easy to install after the wire is overhead, and the force is in good condition, and it has good electrical and mechanical properties; it can be used in conjunction with ordinary tension-resistant clamps without drainage plates and drainage clamps, and can be directly released and hung through the pulley. lines, simplifying the construction process and reducing material waste.

Detailed ways

As shown in Figure 1, a crimping type jumper drainage fitting includes a T-shaped crimping tube 1, a drawer 2 and a drainage clip 3, and the drainage clip 3 is a common drainage clip, as shown in Figures 2 and 3 , the upper end of the T-shaped crimping tube 1 is provided with a fan-shaped ring 4, the two ends of the fan-shaped ring 4 are provided with chute 5, the cross section of the drawer 2 is fan-shaped, and the lower ends of the left and right sides of the drawer 2 are provided with extension items 7 .

As shown in Figure 4, during specific construction, use ordinary strain clamps 10 to connect with the ends of the main line 8 in the elevated transmission line, directly use the pulley to set out and hang the lines, and then select a T-shaped crimping tube of appropriate specifications 1. Make the inner diameter of the fan-shaped snap ring 4 the same as the outer diameter of the main line 8, set the fan-shaped snap ring 4 at a suitable position on the main line 8, slide the extension item 7 into the chute 5 and crimp it, so that The drawer 2 is fixedly connected with the fan-ring snap ring 4, the angle of the sector where the fan-ring snap ring 4 is located is greater than 180°, and the cross section of the combination after the drawer 2 and the fan-ring snap ring 4 is connected is a complete circular ring, Make the connection with the main line 8 tighter and make it easier for the pulley of the tackle to pass through.

The lower end of the T-shaped crimping pipe 1 is a drainage plate 6, and the drainage plate 6 and the drainage clamp 3 are bolted or crimped. The current is introduced into the drain wire 9 .
