Title: Plug
Inventor: OWADA KENJIRO
IPC: H01R24/02
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a plug which takes power from an earphone jack of a television or others without cutting a speaker, has good contact, and has no damage. SOLUTION: A contact conductor 16 on the plug side is a cut conic metal A spring shaft 15 made of linear material is fixed at its one end, expands through the center of a sleeve 12, and has the contact conductor 16 fixed at its another end. The jack 1 has an electric contact consisting of a fixed armature 2 and a spring armature 3 in its speaker circuit. When the plug is inserted into the jack 1, the contact conductor 16 contacts with the spring armature 3. However, the contact pressure is not large enough to move the spring armature 3, and therefore sound can be heard with an earphone without cutting a speaker. Because the contact conductor 16 is a cut conic metal, its contact with the spring armature 3 is good, and no plug is fell or damaged.
