Description

This invention relates to a connector used for connecting to electronic devices, etc., which can provide a stable electrical connection to the electronic devices, etc. In connectors used for connecting to electronic devices, such as those used for connecting to imaging devices, it is extremely important to stabilize the electrical connection between the imaging device and the connector in order to reliably transmit and receive imaging signals (electrical signals) generated by the imaging device. As a connector used for connecting to such electronic devices, an external connection connector 13 is known, which is provided in the housing 5 of the imaging device 1 and electrically connected to the imaging device 1 (see, for example, Patent Document 1). The external connection connector 13 includes a shielding member 16 acting as a conductor and a cylindrical contact piece 22 that slides against the shielding member 16 due to the biasing force of the coil spring 23. The cylindrical contact piece 22 also includes a sliding contact 22a and an annular contact 22b. The sliding contact 22a is electrically connected to the shield member 16 and is locked to the retaining locking portion 16c of the shield member 16. The annular contact 22a also makes conductive contact with the substrate 10 inside the imaging device 1. In this way, the imaging device 1 and the external connection connector 13 are electrically connected.
