[0002]

2. Description of the Related Art When an electric device takes some measures against an electric input from the outside, the conventional method receives an external input at a terminal block, and the terminal block is wired into the device so that a board or various types of devices can be connected. It was connected to the element. In this method, the terminal block is merely a relay terminal and does not have a function of converting an electric signal by itself, and occupies a certain space as a relay terminal. In this method, since a space is used only as a relay terminal, it is necessary to use a space other than the portion occupied by the terminal block in the electric device for the substrate and various elements.

When a fuse or diode is inserted between the terminal block and the input cable when conducting a test on an electric device, an empty terminal block is used to perform two relays or an electric wire with a clip. A fuse or diode was attached to the wire, and the wire used to relay between the input cable and the terminal block.

[0004]

When the electric device takes some measures against electric input from the outside, in the conventional method, the input signal is once passed through the terminal block as a relay terminal and then into the electric device. Introduced. Also, when testing electrical equipment, when inserting a fuse or diode, space is wasted due to the use of an empty terminal block, and when using an electric wire with a clip, the clip easily comes off from the terminal, There was a risk of ground fault, short circuit, and electric shock.

The object of the present invention is not only to relay the input from the outside by the terminal block, but also to incorporate the elements and switches in the terminal block so that the space conventionally used in the device can be stored inside the terminal block. By using the terminal, it is possible to save space, and by using a detachable contact terminal (cartridge) that has a built-in element surrounded by an insulator, it has an additional function with high electrical safety. It is to provide a stand.
