Abstract

A connector includes a housing body, a shield shell that externally covers the housing body, a first connection terminal that is housed in the housing body, electrically connected to a first wire in the housing body, and electrically connected to a counterpart terminal when the connector is connected to a counterpart connector, and a circuit protection component that is interposed, in the housing body, between the first connection terminal and the first wire, and connects the first connection terminal and the first wire in series to protect a circuit. The housing body includes at least one thermal conductor that performs thermal conduction with the circuit protection component by being in contact with the circuit protection component.
