Description

Cable wire end point joint structure

This invention relates to a cable wire terminal joint structure, and in particular to a cable wire that can be installed or docked with a terminal device, with the terminal joint fixing technology as the primary application of the invention.

In general, overhead transmission and distribution lines are constructed by raising cables above the terrain using support towers such as support towers (e.g., high-voltage cable towers). Transmission and distribution lines may span many miles and require extremely long lengths of cable, for example, where many cable segments are connected together for electrical and mechanical continuity, and many support towers. Some of the support towers are called dead-end towers or anchor towers, such as towers. Such towers are located at termination points, such as power substations or locations where the wires are routed underground. Terminal towers, such as pylons, may also be needed where wires change direction (e.g., bends); where they cross roads or other structures where there is a high risk of damage or injury if the cable fails; or at regular intervals on long straight line runs. In such instances, the overhead cable must be terminated (e.g., cut), secured under high tension to a terminal tower, and electrically connected to adjacent overhead cables.

As can be seen from the above, when the cable is adapted to different geographical environments, locations or docking objects, whether it is fixed to the terminal tower, disconnected and fixed, or terminated, it must be perfectly connected and conductive; and the traditional mandrels that support the strength of the cable are mostly made of steel cables. Although the steel cables have strength, the metal is too heavy to operate and install, so light alloys such as carbon fiber are used for improvement. Carbon fiber has strength and light weight, which effectively improves the weight problem. However, light alloys cannot use traditional strong locking methods for bonding and fixing, because although carbon fiber has good strength, it is brittle and cannot withstand external forces. As a result, the industry has made great efforts to research and develop innovative technologies to solve this problem as soon as possible.

Today, the creators, in the spirit of continuous improvement and based on their rich design, development and actual manufacturing experience in the relevant industry for many years, have provided a cable and wire end point joint structure in the hope of achieving better practical value.

The main purpose of this invention is to provide a cable wire end point joint structure, especially an end point joint fixing technology for a cable wire that can be installed or docked with a terminal device.

The main purpose and function of this cable wire end joint structure are achieved by the following specific technical means:

A strength mandrel is mainly provided at the center of the cable wire. When the cable wire is installed with a corresponding terminal device or fixed by docking, a sleeve can be provided on the outside of the strength mandrel, and a buffer is provided between the sleeve and the strength mandrel; thereby, when the sleeve is pressed, the buffer can protect the strength mandrel from being damaged by external pressure.

In a preferred embodiment, when the invention is used in combination with a terminal device, the terminal device has a connector connected to a terminal tower, the connector corresponds to and assembles a terminal unit, and the terminal unit has a conductive outer tube in which a cable wire is embedded and fixed.

In a preferred embodiment of the present invention, the open end of the conductive outer tube is further processed and coated on the outside of the cable wire.

In a preferred embodiment, the invention, when used for docking and fixing, has two cables, and the strength core shafts of the two cables are respectively provided with buffer parts, and then a sleeve is correspondingly provided so that the strength core shaft sections of the two cables are located in the sleeve, and after the two strength core shafts are compressed and covered, a conductive outer tube is covered on the outside of the two cables, and the two cables are fixed by covering the conductive outer tube.

In order to make the technical content, purpose and effect of this creation more complete and clear, we explain it in detail below. Please also refer to the disclosed diagrams and figure numbers:

First, the cable wire end point joint fixing structure of the present invention can be used for combination or docking with a terminal device. The structural features are described in detail below. Please refer to the first figure, which is a cross-sectional schematic diagram of the first embodiment of the present invention. The first embodiment is used for combination with a terminal device and mainly includes:

A terminal device (1) has a connecting piece (11) connected to a terminal tower, the connecting piece (11) corresponds to and is assembled with a terminal unit (12), the terminal unit (12) has a conductive outer tube (4), a cable (2) is embedded and fixed in the conductive outer tube (4), a strength mandrel (21) is provided at the center of the cable (2) and is located in the conductive outer tube (4), a sleeve (3) is sleeved outside the strength mandrel (21), and a buffer (22) is provided between the sleeve (3) and the strength mandrel (21);

The sleeve (3) is pressed to cover the strength spindle (21), and the buffer (22) provides a function of relieving the pressing process and protecting the strength spindle (21).

However, in one embodiment of the present invention, the open end of the conductive outer tube (4) is processed and wrapped around the outside of the cable wire (2) to achieve the effect of power supply.

Please refer to the second to fifth figures, which are schematic cross-sectional views of the decomposition and assembly of the second embodiment of the present invention. The second embodiment is used for docking and fixing, and mainly includes:

The two cables (2) are provided with a strength mandrel (21) at the center, and a buffer member (22) is respectively sleeved outside the two strength mandrels (21);

A sleeve (3) having two openings at its two ends for respectively inserting the strength mandrels (21) of the two cables (2), and the sleeve (3) is compressed to cover the two strength mandrels (21);

A conductive outer tube (4) is correspondingly sleeved on the outside of the strength core shaft (21) of the two cable wires (2) and covers and fixes the two cable wires (2).

For example, two broken cables (2) are connected and fixed. After the two cables (2) are reshaped, a strength mandrel (21) of appropriate length is pre-set, and a buffer (22) is respectively sleeved on the outside of the two strength mandrels (21). Then, a conductive outer tube (4) is sleeved on one of the cables (2). After that, the strength mandrels (21) of the two cables (2) are respectively sleeved by the sleeve (3). The two ends are opened so that the two strength core shafts (21) are located in the sleeve (3). After the pressing process, the sleeve (3) covers the two strength core shafts (21) to connect the two cables (2). Then, the conductive outer tube (4) sleeved on one of the cables (2) is pushed and sleeved on the outside of the sleeve (3) and covered on the outside of the two cables (2) through processing to achieve the effect of power supply.

The aforementioned embodiments or diagrams do not limit the structural form of the present invention. Any appropriate changes or modifications by a person having ordinary knowledge in the relevant technical field should be deemed to be within the patent scope of the present invention.

From the above description, it can be seen that compared with the existing technical means, this invention mainly has the following advantages:
