  • This miniature USB connector is approximately 1/8 the size of a conventional USB connector. Because of this small size, it is highly desirable for use in portable electronic equipment.
  • This connector has five terminals, in which an ID terminal for identification of host equipment is assembled in addition to conventional signal lines.
  • Mini-AB USB connector which is the latest series of USB regulation
  • a plug connector of either of A type and B type is inserted into a receptacle connector mounted on a board side. It was found that, at this time, in order to judge whether A type or B type plug connector is inserted, the correlation of fourth and fifth pins is set as follows.

Abstract

Cette invention se rapporte à un connecteur électrique comprenant au moins deux bornes (1-5) qui sont court-circuitées l'une par l'autre, grâce à l'utilisation d'une partie continue (6). La partie continue est formée pendant le processus de fabrication des bornes, ce qui simplifie le court-circuitage des deux bornes au moins, l'une par l'autre.
