Elektrische Mehrpol-Kontaktbuchse

摘要

The present invention relates to a multipolar electrical jack (multipolar jack) which uses a multipolar electrical plug (multipolar plug) as a counter electrical connector. According to the present invention, even when a jack is of a multipolar type, the length of the jack can be shortened. The multipolar jack of the present invention is useful as a multipolar electrical connector to be used where space for insertion and ejection of the jack is required to be as small as possible, such as the case of an audio apparatus and a car navigation apparatus mounted on an automobile. In the multipolar jack of the present invention, a body is provided with an annular recess and a center recess positioned at the center of the annular recess of the body. Three poles are separately disposed on the annular recess of the body and the center recess, respectively. The poles are disposed in a distributed manner on the inner and outer peripheral faces of the annular recess of the body.
