  • Publication number: 20070249235
    Abstract: An audio jack connector includes an insulating body and a plurality of contacts. The insulating body has a main body and a mating portion integrally formed at one end of the main body. A mating hole crosses through the mating portion and extends into the main body. A plurality of contact grooves is defined in the insulating body. Each contact groove communicates with the mating hole and each contact groove communicates with outside. Each contact has a holding part, a touching part and a compression part. The holding part of the contact is held in the corresponding contact groove. The compression part extends out the insulating body. The touching part extends into the mating hole. Wherein one of the contact grooves communicates with the mating hole through the mating portion, and the touching part of the contacts extends into the mating hole through the mating portion.

  • Patent number: 7238059
    Abstract: An audio jack connector includes an insulating housing and a first set and a second set of conductive contacts. A plurality of recesses is provided in the insulating housing. Each contact has a fixing portion, a contacting portion and an elastic compressing portion. The first and second sets of conductive contacts are received in the plurality of recesses, the elastic compressing portions of the first set of conductive contacts is located at a middle position of a lateral wall of the insulating housing; the elastic compressing portions of the second set of conductive contacts are located at a middle position of the opposite laterally wall of the insulating housing. While the audio jack connector is assembled with an external printed circuit board having a gap, the audio jack connector embedded into the gap, so the assembly height of the audio jack connector is reduced.

  • Patent number: 7011537
    Abstract: A SIM card connector includes a housing base and a card ejection mechanism. The housing base has a pair of sidewalls, a front notch and a rear notch recessed in the sidewall. The card ejection mechanism includes a cover slidably mounted on the housing base to form a receiving cavity for receiving a SIM card. The cover has a pair of side panels to enclose the sidewalls. According to an aspect of the invention, the side panel defines a sliding slot. The sidewall forms a locating block received in the sliding slot to guide the sliding of the cover and prevent the cover from further sliding when the locating block engages with the ends of the sliding slot. According to another aspect of the invention, the front and rear ends of the housing base respectively form a stopping bar and a stopping block to prevent the cover from further sliding.
