MULTIPOLE JACK MULTIPOLE PLUG AND STRUCTURE FOR CONNECTING THE MULTIPOLE JACK AND THE MULTIPOLE PLUG

摘要

PURPOSE: To prevent two additional electrodes from being short-circuited when a multi-polar plug equipped with a ring-shaped electrode is connected to a base part of a plug shaft part, in the case the two pole numbers are added utilizing a cylindrical part of the body as for a multi-polar jack (6 poles), aim at a downsizing as for the plug, and enable a compact shaped connection as for a connecting structure. CONSTITUTION: Four main electrodes 21 to 24 at the inner side of a jack side body are brought into contact with four main electrodes 61 to 64 of the plug side shaft part. On both right and left sides of a jack side cylindrical part 12, the first additional electrode 25 and the second additional electrode 26 are positioned being shifted forward and backward and inside and outside direction. The first ring-shaped electrode 65 and the second ring-shaped electrode 66 are installed concentrically at the plug side base part 40.
