  • Patent number: 5572408
    Abstract: A data card is provided which has an electrically conductive rail (70, 72 FIG. 2 ) extending along its opposite sides and part of its rear, and connected to the ground plane (60) of a circuit board (46) of the card, to provide EMI (electromagnetic interference) shielding along the perimeter of the card. The rail has top and bottom edge portions (94, 96 FIG. 6) that are each bent into a U shape to extend around top and bottom ridges at the side of the card body to lock the rail in place. One edge portion includes a projecting tab (110) which is bent to extend inwardly and engage the ground plane (60) of the circuit board. The molded card body has a through hole (114) in its side portion, and the tab can extend into that hole before extending inwardly to the circuit board ground plane.

  • Patent number: 5542861
    Abstract: A low-cost miniature coaxial connector is provided, which attaches securely to a coaxial cable. The connector includes inner and outer contacts (30, 32, FIG. 2) constructed of rolled sheet metal and separated by an insulator (34). An inner ferrule (70) formed from a seamless tube, is first crimped around the jacket (24) of the coaxial cable. The braided outer conductor (22) of the cable is wrapped backwards around the crimped inner ferrule. The rear end (60) of the outer contact is held tightly around the braiding by an outer ferrule (72) that is crimped around the rear end of the outer contact. By crimping to the jacket (24) of the cable, the connector is securely held to the cable to withstand relatively large forces pulling the cable away from the connector. The sheet metal outer contact (32) can be reliably crimped in place by the seamless outer ferrule (72) which is crimped around it to hold it tightly around the braiding of the cable outer conductor (22).

  • Patent number: 5362255
    Abstract: A coaxial connector is described, of the type that has a shell (14, FIG. 1 ) with a tubular first portion (16) whose front mates with another connector and whose extreme rear end (64) is initially open, and which has a second portion (22) extending at a right angle to the first portion for mechanically and electrically terminating to the braiding (42A) of a coaxial cable (30). The second portion (22) of the shell forms a tubular ferrule that surrounds the cable inner insulation (40) and which is surrounded by the cable braiding. The connector includes a sleeve (46) which can slide along the cable to a position surrounding the braiding that surrounds the ferrule, so crimping of the sleeve locks the braiding between the ferrule and sleeve. The shell second portion includes first and second parts (50, 52) that extend respectively from the lower and upper sides (60, 62) of the rearward end (56) of the first shell portion, with the second part being bendable and each part forming about half of the tubular ferrule.

  • Patent number: 4919626
    Abstract: A connector for an IC memory card having a printed circuit member mounted within the housing of the card which extends into a slot opening at the edge of the card. The connector contains two rows of contacts which are engageable with conductive traces on the opposite sides of the printed circuit member when the card is inserted into the connector. The contacts in the connector are reversely bent to form inner arms joined to outer arms by nose portions. The inner arms of the contacts in the two rows are normally spaced apart a distance greater than the thickness of the printed circuit member so that when the card is initially inserted into the connector, the noses of the contacts will pass freely over the border of the printed circuit member. Thereafter, the sidewalls of the housing of the card cam the outer arms of the contacts inwardly, forcing the inner arms into engagement with the traces on the printed circuit member in the card.
