Description

Terminal cap and terminal block utilizing same

The present invention relates to a terminal cap and a terminal block using the same, and in particular, a terminal used to connect a communication line (hereinafter referred to as a 'line line') or a subscriber line's communication line (hereinafter referred to as a subscriber line) to a terminal pin. It relates to a cap and a terminal block using the same.

Conventionally, when connecting a communication line to the terminal pin, one had to peel off the sheath of the communication line and connect it, which was very cumbersome. Accordingly, when a communication line to be connected is inserted into a terminal without having to remove the cover of the communication line, a connecting device for automatically contacting the terminal while cutting the cover of the communication line has been developed and widely used. Related to this is described in the Korean Utility Model Publication No. 20-0172411, Terminal Block for Telephone Line Connection. It is configured to insert the electric wire into the wire insertion hole formed horizontally in the electric wire guide and lock the tightening bolt so that the electric wire is inserted and connected to the electric wire connecting pin while the electric wire is lowered. The terminal board for telephone line connection is integrated with a large number of wire connecting pins and wire guides. In the case of using such a terminal plate, it is very difficult to insert the electric wire into the electric wire insertion hole formed in the electric wire guide, and the efficiency of the electric wire connection work is inferior.

The above-described principle has been developed to be able to connect the telephone line, etc., but there is a problem that the efficiency of the communication line connection work is reduced because all the holes for the communication line, such as the wire, that is, the telephone line is formed horizontally.

In addition, conventionally, when the terminal cap is lowered after inserting a telephone line to be connected to the terminal cap, two parts are simultaneously inserted into a gap formed in the terminal pin, and thus, too much resistance is initially received to connect the terminal pin to the telephone line. There is also a disadvantage that this is not done smoothly.

In addition, the conventional terminal block was inconvenient because it was fixed to the support plate of the terminal box using a separate fastener such as a bolt.

The purpose of the present invention is not only to easily insert a communication line such as a telephone line to be connected to the groove, but also to connect the communication line to the terminal pin fixed to the terminal board by allowing the communication line inserted in the groove to be easily inserted into the terminal pin. It is to provide a terminal cap to make the work easier.

Another object of the present invention is to provide a terminal block utilizing the terminal cap of the present invention.
