George (Huanyi) Zhang - Irvine CA, US
Gustavo F. Duenas - Placentia CA, US

Assignee:

Hon Hai Precision Ind. Co., Ltd - Taipei Hsien

International Classification:

H01R 24/00

US Classification:

439660, 4399241

Abstract:

An electrical connector () comprises an insulative housing including a mating tongue () exposed in a mating port (), and three type contacts. The mating tongue has a front face () thereof. The three type contacts include two power contacts () being on two opposite side regions of the mating tongue, three signal ground contacts () located between said two power contacts, and two pairs of signal contacts () each located between the corresponding two adjacent signal ground contacts. One of the two power contacts () extends much closer to the front face of the mating tongue than the other () of the two power contacts. This arrangement of two different-lengths has the ability to handle the instantaneous inrush current through the former power contact, i. e. the pre-charge power pin.

International Classification:

H01R 24/00

US Classification:

439660, 439108

Abstract:

An electrical connector includes a row of terminals () having a pair of differential signal terminals () mounted on a mating tongue (). Each of the signal contact terminals has a rear end () on a back outer face of the connector and a free mounting end () away from the back outer face. The free mounting ends are located on a first end row and bent from the rear ends and away from each other in opposite transverse directions so as to widen a pitch therebetween to improve impendence for decreasing interference.

International Classification:

H01R 24/00

US Classification:

439660

Abstract:

An electrical connector includes an insulated housing and a plurality of contact loaded in the insulated housing. The insulated housing defines an uninterrupted longitudinal slot extending in a first direction and through a mating face in a second direction perpendicular to the first direction the slot having a first and a second inner side faces facing to each other. The first inner side defines a groove extending through the mating face in the second direction. Each contacts includes a retaining portion retained in the insulated housing, a contacting portion exposing in the slot and a tail portion. The contacting portions defines a mating orientation along which the contacting portions contact with corresponding contacts of a counter electrical connector intended to be inserted in the slot. The plurality of contacts includes a first group and a second group of contacts lined along the first side face of the slot at opposite sides of the groove, and a third group, a forth group and a fifth group of contacts lined along the second side face. The third group of contacts are aligned with the groove, the forth group of contacts faces to the first group of contacts and the fifth group of contacts faces to the second group of contacts in a third direction perpendicular to the first and second directions.

International Classification:

H01R 24/00

US Classification:

439629, 439637

Abstract:

An electrical connector includes an insulated housing defining an uninterrupted tongue portion with opposite first surface and second surface, the first surface defining a rib and a plurality of contacts loaded in the tongue portion. The contacts include first contacts with contacting sections loaded in the first surface at one side of the rib, second contacts with contacting section loaded in the first surface at another side of the rib and third contacts with contacting section loading in the second surface opposite to the rib. Each of the first and third contacts is composed of signal contacts and grounding contacts. Two distinct grounding bars are embedded in the tongue section and touch with front ends of grounding contacts of the first and third contacts respectively to reduce cross talk between signal contact of the first and third contacts.
