20090149081Audio Jack connector and contact thereof with improved strong intensity contact portion - An audio jack connector includes an insulative housing and a conductive contact retained in the insulative housing. The insulative housing defines a plug receiving hole for receiving a mating plug and a mounting space located at one side of the plug receiving hole. The conductive contact has a stationary portion received in the mounting space, a spring arm forwardly extending from the stationary portion and a curly contact portion extending backwardly from the spring arm and protruding into the plug receiving hole. The curly contact portion includes opposite first and second ends in condition that the first end connects with the spring arm-and the second end abuts against an inner surface of the spring arm.06-11-2009
20090253308Electrical connector with improved contacts - An electrical connector (10-08-2009
20090264020Electrical connector with improved contact position structure - An electrical connector (10-22-2009
20090298336ELECTRICAL CONNECTOR WITH IMPROVED CONTACT ARRANGEMENT - An electrical connector includes an insulative housing, a set of first contacts retained in the insulative housing and a metal shell. The insulative housing includes a tongue plate with a plurality of first passageways defined thereon. The first contacts include first contacting sections received in the first passageways, first bending sections and first tail sections. The first bending sections include a plurality of first offset sections and at least one second offset section. A first slope of each first offset section is of negative number while a second slope of the second offset section is of positive number so that a space between each adjacent two first tail sections is much larger than that of the corresponding first contacting sections for easily soldering of the first tail sections.12-03-2009
20090298351ELECTRICAL CONNECTOR WITH IMPROVED CONTACT STRUCTURE - An electrical connector (12-03-2009
20100003854ELECTRICAL CONNECTOR WITH IMPROVED EMI STRUCTURE - An electrical connector includes an insulative housing, first and second contact modules received in the insulative housing, a first metal shell covering the insulative housing and a grounding piece. The insulative housing includes a mating tongue and the first metal shell includes a plurality of peripheral walls enclosing the mating tongue to cooperatively form a mating opening therebetween. The grounding piece includes a number of side walls and a receiving opening through which the peripheral walls extend. The side walls include a number of half-spherical embosses stamped therefrom to abut against the front metal shell for EMI protection.01-07-2010
