Description

New cable terminal

technical field

The utility model relates to the technical field of electric power, in particular to a novel cable connection terminal.

Background technique

In recent years, with the wide application of power cables, the number of connection points between power cables and overhead conductors has increased rapidly. The traditional connection method in construction is that the end of the power cable is a pipe nose, and the front end of the pipe nose is a round hole. Install the equipment clamp at the end, process a perforation at the flat end of the clamp, and press the two perforations together with bolts to form the connection between the power cable and the overhead conductor. The traditional construction method has the following defects: First, through the connection between the pipe nose and the equipment clamp, due to the small flat surface of the pipe nose, the contact area between the two is relatively limited, and the carrying capacity of the contact surface is insufficient, causing the contact surface to overheat; secondly, through the bolt When the two are pressed tightly, the surface-to-surface pressure is insufficient, and the tightness of the contact surface is affected. In a high-pressure environment, the connection surface is oxidized and damaged.

Contents of the invention

In order to solve the deficiencies in the prior art, the utility model provides a new type of cable terminal, which simplifies the construction process, improves the construction efficiency, and solves the problem of insufficient carrying capacity of the contact surface.

The technical scheme that the utility model solves its technical problem adopts is:

A new type of cable terminal, including a terminal body, the front end of the terminal body is connected to an overhead wire splint through fastening bolts, and a slightly protruding part between the overhead wire splint and the terminal body forms a groove with an inner arc surface Body, the length of the groove body is 5-10cm, the overhead wire splint and the terminal body are connected together to form an overhead wire clamp groove, and the rear end of the terminal body is provided with a cable core wire pressure groove for fixing the cable chip.

The beneficial effects of the utility model are: the device combines the connection of the traditional equipment clamp and the two connecting fittings of the terminal into a new type of terminal. In the effective original construction method, there are problems such as insufficient carrying capacity of the contact surface, easy loosening, and easy corrosion. At the same time, it simplifies the construction process and improves the construction efficiency.

Fig. 1 is the top view structural representation of the utility model;

Fig. 2 is a side view structural representation of the utility model;

In the figure: 1. Overhead wire clip groove, 2. Fastening bolt, 3. Overhead wire splint, 4. Terminal body, 5. Cable core wire pressure groove.

Detailed ways

As shown in Figures 1 and 2: a new type of cable terminal, including a terminal body 4, the front end of the terminal body 4 is connected to an overhead wire splint 3 through a fastening bolt 2, and the overhead wire splint 3 is connected to the terminal body 4. A slightly protruding part in the middle forms a groove body with an inner arc surface. The length of the groove body is 5-10 cm. The overhead wire splint 3 is connected with the terminal body 4 to form an overhead wire clamp groove 1. The connection terminal The rear end of the body 4 is provided with a cable core wire pressing groove 5 for fixing the cable chip.

The front end of the terminal body 4 is extended and modified to make an overhead wire clamp groove 1 capable of placing overhead wires, and the overhead wire splint 3 and the terminal body 4 are fixedly connected by fastening bolts 2, so that the device can increase the size of the wire. The contact surface with the cable terminal makes the carrying capacity of the contact surface significantly improved and meets the test requirements.
