Abstract:
1. An electric connector that is, for allowing information transmission/reception apparatuses incorporated in a plurality of vehicles constituting a train to transmit and receive train information in an interconnecting manner via an in-vehicle cable, interposed between the in-vehicle cable and the information transmission/reception apparatus, wherein the in-vehicle cable internally includes a plurality of signal lines that transmit the train information and an electrically-conductive shielded layer surrounding the signal lines, one end of a ground line is connected to the electrically-conductive shielded layer, the signal lines are connected to connector pins that are installed in an electrically-conductive connector case, which is a casing of an electric connector with a width in a lateral direction narrower than a width in a longitudinal direction, and that are electrically insulated from the electrically-conductive connector case, a casing ground is provided to a casing of the information transmission/reception apparatus, and a plurality of contact pins electrically insulated from the casing of the information transmission/reception apparatus and electrically connected to the connector pins are provided to the casing of the information transmission/reception apparatus, and the other end of the ground line is connected to the electrically-conductive connector case in a detachable manner, and the electrically-conductive connector case is electrically connected to the casing of the information transmission/reception apparatus in a state where the contact pins and the connector pins are respectively connected to each other, a terminal block is provided on a side surface of the electrically-conductive connector case to be interposed between an electrically-conductive terminal provided to the other end of the ground line and the electrically-conductive connector case and fixes the terminal by using a fixing member, and the electrically-conductive terminal has the fixing member inserted through at a central portion thereof and is formed in a shape of a flat plate.
