Plug and socket.

摘要

In a plug, an insulating body is disposed in a cylindrical metallic shield cover, a plurality of signal contacts and two power supply contacts are held by the insulating body axially thereof and are separated by a square-sectioned partition wall extending from the insulating body. The front end face of the partition wall lies forwardly of the tips of the contacts. In a socket to which the plug is put, a plurality of signal contacts and two power supply contacts are held by an insulating body axially thereof. A cylindrical metallic member (25) is mounted in the body in a manner to surround the contacts. In the cylindrical member a columnar key (26) extends forwardly from the insulating body on the center axis of the cylindrical member. The power supply contacts are housed in slots made in said columnar key and extending rearwardly from its front end face. Support plates (27, 28) extend from the insulating body on both sides of the columnar key in opposed but spaced relation thereto, and the signal contacts are housed in housing grooves cut in the support plates on one sides thereof and extending axially thereof. The tips of the power supply contacts and the signal contacts lie short of the front end portions of the columnar key and the support plates.
