Electrical connector with plug and socket

A connector, characterized by comprising:

• a plug including a first connection member;
• and
• a socket including a second connection member to which the first connection member is detachably connected from a first direction, the second connection member being configured to be rotatable with respect to the first connection member between a first position where the first connection member is detachable from the first direction and a second position where the first connection member is not detachable from the first direction in a circumferential direction with respect to a center line extending in the first direction, wherein
• the first connection member includes:
• a first body portion that extends along the first direction;
• and
• a claw portion that protrudes from the first body portion in a radial direction with respect to the center line,
• the second connection member includes:
• a second body portion that extends along the first direction and is configured to be connectable to the first body portion, a part of the second body portion being located outside the first body portion in the radial direction;
• and
• a connection groove portion which is located in a portion of the second body portion facing the first body portion and accommodates the claw portion,
• the connection groove portion includes:
• a first groove portion that extends along the first direction from an end portion of the second body portion facing the first connection member and is configured to guide movement of the claw portion in the first direction in a state where the second connection member is located at the first position;
• and
• a second groove portion that is connected to an end portion of the first groove portion far from the first connection member in the first direction, extends along the circumferential direction, and is configured that the claw portion is movable in the circumferential direction, and is configured to restrict movement of the claw portion in the first direction and in a direction approaching the plug in a state where the second connection member is located at the second position, and
• the second body portion includes
• a restricting portion that is provided at a position different from the first groove portion at the end portion facing the first connection member and is configured to accommodate the claw portion and to restrict rotation of the socket with respect to the plug in the circumferential direction.
