Abstract

An electrical connector and a USB connector are provided. The electrical connector includes a main connector housing having an upper pin housing and a lower pin housing. A stereo plug that protrudes from a front surface of the main connector housing lies between the inner surface of the lower pin housing and the inner surface of the upper pin housing. The electrical connector is adapted to connect to a jack. The upper pin housing and the lower pin housing are adapted to connectively engage a forward plug port housing of the jack. The jack is mounted within the casing of an electronic device such as a hand-held personal computer, a personal digital assistant, a wireless telephone, or a paging device. When the electrical connector is connected to the jack, the upper pin housing is inserted into an upper housing receiving port and the lower pin housing is inserted into a lower housing receiving port so that the electrical connector is mated to the casing of the electronic device. The improved USB connector includes a connector body, a USB connector plug, an alignment post and electrical power contacts on each side of the alignment post. A locking latch may be disposed along an upper surface of the alignment post for engaging a locking latch detent disposed in an interior upper surface of the alignment post port.
