A plug-in type connector is connected to the end of the inside cable. A first terminal block has U-groove clip terminals which are connected to the plug-in connector. A second terminal block has U-groove clip terminals which are connected via jumper wires to the clip terminals of the first terminal block. A third terminal block has U-groove clip terminals which are connected to the outside cable. A receptacle having female contact terminals is connected to the clip terminals of the second and third terminal blocks, the receptacle also having a female contact terminal for making a ground connection. This receptacle also receives male contact terminals of a protector module which includes a protection device. At least one back wiring board has the connector, the first, second and third terminal blocks and the receptacle mounted thereon. A shelf has the back wiring board fixed thereon for mounting the connector, the first, second and third terminal blocks, and the receptacle on the MDF, in an integrated form.
