Twisted pair cable joint connector

A joint connector for connecting high potential wires and connecting low potential wires included in twisted pair cables each including the high potential wire and the low potential wire, comprising:

• high potential wire terminals to be mounted on the respective high potential wires;
• low potential wire terminals to be mounted on the respective low potential wires;
• sub-housings respectively corresponding to the plurality of twisted pair cables, each sub-housing being configured to hold the high potential wire terminal and the low potential wire terminal of the corresponding twisted pair cable arranged in a specific terminal arrangement direction;
• a main housing including a sub-housing insertion opening open in a specific direction, the main housing being configured to accommodate the sub-housings in such an array that the sub-housings are stacked in a housing stacking direction intersecting the terminal arrangement direction by receiving the sub-housings inserted in a housing insertion direction parallel to an axial direction of the high potential wire terminals and the low potential wire terminals through the sub-housing insertion opening;
• a high potential connection conductor held in the main housing, the high potential connection conductor including high potential connection terminals fittable to the high potential wire terminals respectively held in the sub-housings in a direction parallel to the housing insertion direction and a high potential shorting portion for shorting the high potential connection terminals to each other, the high potential connection conductor being configured to connect the high potential wire terminals to each other;
• a low potential connection conductor held in the main housing, the low potential connection conductor including low potential connection terminals fittable to the low potential wire terminals respectively held in the sub-housings in a direction parallel to the housing insertion direction and a low potential shorting portion for shorting the low potential connection terminals to each other, the low potential connection conductor being configured to connect the low potential wire terminals to each other;
• and
• a holding member to be mounted into the main housing to hold each of the sub-housings inserted into the main housing;
• each of the sub-housings including a restrained portion;
• and
• the holding member including a housing restraining portion extending in a restraining portion insertion direction crossing the sub-housings stacked in the housing stacking direction, the housing restraining portion restraining the restrained portions to impede the withdrawal of each sub-housing from the main housing in a direction opposite to the housing insertion direction by being inserted into the main housing along the restraining portion insertion direction with each of the sub-housings inserted in the main housing.
