Description

Connector for underground distribution line connection only {Connector}

The present invention relates to a connector for connection to an underground power distribution line, and more specifically, when a certain amount of impact occurs in the ground, the underground power distribution line is safely short-circuited in advance at the corresponding position, but the durability of the structure to be inputted in the short circuit is efficiently secured to achieve an accurate disconnection. It relates to a connector for connection to an underground distribution line that can be made.

Usually, a distribution line is a wire for distributing electricity and is buried underground.

Most of these power distribution lines are buried by lengthening them to minimize leakage of electricity to be distributed, but in areas where connection is required, they are connected using connectors for connection only.

In the conventional underground buried type distribution line, when an excessive external force is applied, the distribution line is disconnected from the portion where the external force is applied, making it difficult to find the disconnected portion, so that the entire transmission line must be rebuilt.

Accordingly, conventionally, when an external force is applied to the ground, the power distribution lines are separated from each other, the connection terminals are provided with them, and the terminals are rotated to control on and off.

However, in the related art, the terminals are relatively rotated, but in the case of a short circuit, they are rotated by a rotating means such as a motor, so that the terminals are physically separated from each other.

Therefore, in the related art, if the rotation axis is twisted by an external force as the terminals are physically separated as the terminals are repeatedly rotated, there is a problem in that the terminals may be damaged if they are rotated and collide with each other to maintain the on state.
