Abstract: A dustproof receptacle connector includes a dielectric housing, a plurality of terminals, a shield and a dustproof cover. The dielectric housing defines a plurality of terminal grooves therein for receiving the terminals. The shield surrounding the dielectric housing has a top board. A sliding groove is defined in the top board and extends longitudinally to pass through a rear end of the top board. An engaging portion extends from the rear end of the top board. A receiving groove is surrounded by the engaging portion and the rear end of the top board and communicates with the sliding groove. The engaging portion is bent downward to be attached to a rear portion of the dielectric housing. The dustproof cover is slidably received in the shield and located between the dielectric housing and a front end of the shield. The dustproof cover has a positioning portion slidable along the sliding groove.

Abstract: An electrical connector includes an insulating housing having a front frame and a rear frame engaged with the front frame. The front frame defines at least two receiving grooves at a top portion and a bottom portion thereof respectively. The rear frame defines at least one fixing groove passing through a front portion thereof. At least one latch member has a hollowed bearing portion extending from both distal ends thereof to form two resilient arms. The bearing portion and the resilient arms are received in the fixing groove of the rear frame. A tip end of each resilient arm extending into the corresponding receiving groove protrudes to form a limiting portion which is exposed out of the receiving groove of the front frame, and a plurality of terminals is disposed in the insulating housing respectively.

Abstract: An electrical connector includes a dielectric housing, a plurality of terminals and a shield. The dielectric housing defines a plurality of terminal grooves therein for receiving the terminals. At least one recess is formed in an outer surface of the dielectric housing. The shield has a plurality of sidewalls to define a receiving space therebetween for receiving the dielectric housing therein. At least one of the sidewalls is punched inward at a portion corresponding to the recess of the dielectric housing to form a retaining portion restricted in the recess after the dielectric housing is mounted in the receiving space. The retaining portion is restricted in the recess for fixing the dielectric housing inside the shield. The depth of the recess and the retaining portion restricted in the recess is not limited by the depth of the material of the shield. The dielectric housing is fixed in the shield firmly.

Abstract: An electrical connector includes a housing having a plurality of terminals received within and a shell encircling the housing therein. The shell has a mating opening at one end thereof. A dustproof cover is assembled in the shell and positioned between the mating opening and the housing to perform anti-dust function. The dustproof cover has an insulator and a metal sheet combined with the insulator to strengthen the structure of the dustproof cover. The dustproof cover is of enough intensity and is not prone to deformation in use and therefore offers fully anti-dust function for the electrical connector.

Abstract: A receptacle and plug connector assembly includes a receptacle having a housing with a plurality of terminals received therein and a plug mated with the receptacle and having an insulator with a plurality of contacts disposed therein. Each terminal has a base portion and two elastic arms extending from the base portion. Free ends of the two elastic arms respectively protrude towards each other to form projections. Each contact has a substantially U-shaped contacting portion received between the elastic arms and pressed by the projections of the elastic arms. Therefore, the terminals of the receptacle contact the contacts of the plug stably.

Abstract: A connector assembly includes a receptacle connector having a first housing with a plurality of first terminals received therein, and a plug connector matched with the receptacle connector and having a second housing with a plurality of second terminals fixed therein. Each first terminal has a first base portion, a first contact portion, a first elastic arm, and a first propping portion formed at a free end of the first elastic arm. Each second terminal has a second base portion, a second contact portion, a second elastic arm, and a second propping portion formed at a free end of the second elastic arm. The first propping portion is against the second contact portion while the second propping portion is against the first contact portion. Therefore, the connection between the receptacle connector and the plug connector is double and more stably.

Abstract: A plug connector includes an insulating housing and a plurality of contacts received in the insulating housing. The insulating housing has a base body and a tongue portion extending rearward from the base body. The tongue portion has a top portion and a bottom portion. Each of the contacts has a substantially U-shaped contacting portion which includes a first contacting branch, a second contacting branch substantially parallel to the first contacting branch and a connecting portion connected one end of the first and second contacting branches together. The first and the second contacting branches of the contacts are respectively exposed at the top and bottom portions of the tongue portion for both electrically contacting terminals of a complementary receptacle connector.

Abstract: A SIM card connector includes a dielectric housing and a plurality of electric terminals. The dielectric housing has a base, a plurality of receiving grooves is opened in the base, a receiving space is formed above the base for receiving a SIM card. The electric terminal secured to the dielectric housing has a fixing portion fixed to the base of the dielectric housing, an elastic portion bending upward from the fixing portion and extending into the corresponding receiving groove, and a contacting portion continuously extending from the elastic portion and protruding into the receiving space to electrically the SIM card. A curving portion is curved downward from the contacting portion, and a connecting portion extends continuously from the curving portion and is fixed to the base.

Abstract: An electrical connector adapted for receiving a first electronic card and a second electronic card has a first connector element that includes a first base having a first body, and a set of first terminals received in the first base. Two lateral walls and two holding walls extending upwards and downwards from two opposite sides of the first body to form a first receiving space and a receiving chamber therebetween respectively. The first receiving space, with a first insertion opening defined, is adapted for receiving the first electronic card. A second connector element removably received in the receiving chamber includes a second base, a set of second terminals mounted in the second base and a second shell. The second shell is engaged with the second base to form a second receiving space, with a second insertion opening defined opposite to the first insertion opening, for receiving the second electronic card.

Abstract: A connector has an insulating housing. The insulating housing has a mating body and a receiving body connected with the mating body. The mating body has a mating surface which defines at least one cavity. The receiving body defines a top surface, a bottom surface and a side surface. A first terminal has a first contacting portion positioned on the top surface and adapted for being connected with a first printed circuit board, and a first connecting portion protruding into the corresponding cavity. A second terminal has a second contacting portion also positioned on the top surface and a second connecting portion extending out of the side surface and adapted for being connected to a second printed circuit board. A third terminal has a third contacting portion also positioned on the top surface and an antenna-connecting portion extending out of the bottom surface for connecting an antenna device.
