Patent ID: 6906527

Claim:
A proximity sensor comprising: a cylindrical outer shell case; a detection coil assembly which includes a coil and a core and which is fitted to a front-end side of the outer shell case; a plug-adaptable connector which is fitted to a rear-end side of the outer shell case; and a circuit assembly which is disposed between the detection coil assembly and the connector and which incorporates an oscillation circuit using the coil as a resonant circuit element and an output circuit for generating an output signal based on the oscillating condition of the oscillation circuit, wherein the connector comprises: a conductive terminal assembly which includes a plug-adaptable conductive terminal electrically connected with the circuit assembly and a pin holder for holding the conductive terminal, and which is sized to be able to be inserted from the front-end side of the outer shell case; and a cylindrical holding member which has openings at both ends so as to enable the conductive terminal assembly to be inserted, which also has a joint part inside to enable the conductive terminal assembly to be positioned thereto, and which is fixed from the rear-end side of the outer shell case, and the detection coil assembly and the conductive terminal assembly are electrically connected with each other with a flexible connection member disposed therebetween.
