BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal block for connecting a conductor to a terminal of a cable formed by covering a conductor with a covering material.

[0002]

2. Description of the Related Art Conventionally, in connecting a conductor (core wire) of a cable to a terminal, usually, a coating material of the cable is peeled off to expose the core wire, and the exposed core wire is connected to the terminal. However, in this case, the work of peeling the coating material is troublesome.

In some cases, the core wires are connected by crimp terminals, but in this case, a tightening tool is required.

In order to cope with this, there is a device in which a groove 2 is formed at the tip of a terminal 1 as shown in FIG. In this device, a cable 5 in which a core wire 3 as a conductor is covered with a coating material 4 is press-fitted into the groove 2 so that the coating material 4 of the cable 5 bites into the edge of the groove 2 so that an inner core wire 4 is formed. And the terminal 1 is made conductive.

[0005]

However, in this case, the width dimension of the groove 2 does not always match the thickness of the core wire 3, and a reliable connection state is not always obtained.

Therefore, an object of the present invention is to connect a cable to a terminal without using a tightening tool and without peeling off a covering material of the cable in advance, and the cable is not affected by the thickness of the cable or the conductor of the cable. An object of the present invention is to provide a terminal block capable of reliably connecting.
