Connector

A connector, comprising:

• an insulating housing;
• an electrically conductive outer conductor to be held in the housing;
• an electrically conductive inner conductor to be surrounded by the outer conductor;
• and
• an insulating dielectric to be interposed between the outer conductor and the inner conductor,
• the housing including a wall-like back wall portion in a direction intersecting a front-rear direction and a tubular peripheral wall portion projecting forward from the back wall portion,
• the back wall portion including an insertion hole,
• the outer conductor including a first outer conductor and a second outer conductor separate from each other,
• the second outer conductor including a tube portion to be passed through the insertion hole and arranged inside the peripheral wall portion and a base portion to be arranged behind the back wall portion,
• the base portion including a through bore communicating with inside of the tube portion, the dielectric being inserted into the through bore,
• the first outer conductor including a bottom portion to be arranged behind the back wall portion to face the base portion,
• the bottom portion including a through hole, an end part of the dielectric being fit through the through hole, and
• a mounting portion to be electrically connected to the circuit board and a positioning portion positionable on the circuit board being provided to project around the through hole in a bottom surface of the bottom portion.
