Connector with rotation restriction

A connector structure comprising:

• a rod-shaped terminal;
• and
• a housing having a terminal accommodating chamber configured to accommodate the terminal, wherein
• the terminal has:
• a rotation restricting portion configured to engage with an inner wall of the terminal accommodating chamber to restrict rotation of the terminal about an axis of the terminal;
• a contact positioned on one side of the terminal in an axial direction of the terminal and configured to be electrically connected to a counterpart terminal;
• and
• a hole provided at an end positioned on an other side of the terminal in the axial direction and configured to allow a bolt to be screwed into the hole about the axis,
• the housing has:
• a holding portion that holds the terminal inside the terminal accommodating chamber;
• and
• an opening configured to expose the hole of the terminal to an outside of the terminal accommodating chamber;
• the connector is configured to have a gap between the inner wall of the terminal accommodating chamber and the terminal, the gap increasing from the rotation restricting portion of the terminal toward the opening of the housing;
• the inner wall of the terminal accommodating chamber has an inclined portion inclined with respect to the axial direction such that the gap increases from the rotation restricting portion toward the opening;
• and
• the rotation restricting portion of the terminal is configured to engage with the inclined portion of the inner wall of the terminal accommodation chamber.
