Description

A "T"-shaped branch connector for power cable branch

technical field

The utility model relates to a branch joint, in particular to a "T"-shaped branch joint which can be installed on an electric pole or a power cable branch in a cable well.

Background technique

With the development of my country's electric power construction and the increased investment in urban power network construction, the demand for power cables is increasing, especially the demand for 10kV power cables is increasing. Compared with the branch connection power of 10kV power cables Cable accessory products are also widely used. At present, the 10kV power cable branch connection products on the market are mainly distribution boxes. It leads the cables to the ground and connects them through the combination of various insulating parts to achieve the branch connection of the power cables. It also needs to install a combined cabinet on the cable well built next to the cable trench, and place the power cable combined joints in it; Its construction is cumbersome in the construction of electric power, and the bulk of the branch cabinets also has a certain impact on the beautification of the city. Especially in large cities in my country, it is difficult to meet the free space required for its installation. More importantly, due to the Putting it on the ground is easy to cause man-made damage and cause unnecessary losses.

Utility model content

The technical problem to be solved by the utility model is to provide a "T"-shaped branch joint for power cable branches with convenient installation, simple structure and small volume.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a "T"-shaped branch joint for power cable branches, which consists of a branch body, an elbow head, a terminal, an outer protective shell, a stress cone, an insulating sleeve, an insertion It is composed of a terminal and a locking ring, and it is characterized in that: the branch body is composed of a "T"-shaped branch insulator and a covered metal shell, and a "T"-shaped branch insulator is provided in the "T"-shaped branch insulator. Conductor, the two ends of the cross arm of the "T"-shaped conductor are respectively provided with plug-in locking threads, and one end of the terminal provided in the elbow head corresponds to the plug-in locking threads, and one end Corresponding to the stress cone set in the elbow head, the outer protective shell is set on the outer layer of the elbow head; the vertical rod of the "T" shaped conductor is provided with a crimping insert The terminal hole and its crimping plug-in terminal and locking ring, the insulating tube is sleeved on the vertical rod of the "T"-shaped branch insulator.

With the power cable branch joint of the above-mentioned technical scheme, the stress cone is inserted into the processed cable, the terminal and the plug-in terminal are connected with the cable conductor by pressing, and the elbow head is first installed into the cable with the crimped terminal. Then use a special screw to connect the cable with the crimped terminal to the plug-in locking thread of the conductor on the branch body; put the insulating sleeve into the cable with the crimped plug-in terminal, and then put the plug-in terminal Insert the "T"-shaped conductor directly, then use the locking ring to lock the "T"-shaped conductor and the plug-in terminal, and put the straight-through insulating tube in place; finally, install the outer protective shell. The utility model is small in size, novel in structure, reliable in performance, and very easy to install; the outside of the main body of the branch is a metal shell, which has good sealing and mechanical properties, and can be installed on the electric pole for branching on the pole, and can also be installed in the cable well , the structure of the branch body can be multi-branched according to the user's requirements, the cable can be branched to the cable, and the overhead bare wire can be branched to the power cable on the pole.

To sum up, the utility model is a "T"-shaped branch joint for power cable branches with convenient installation, simple structure, small volume, convenient manufacture and low cost.
