The cylinder is arranged to pass through a work piece and pressed to form a flattened solid body so as to clamp the work piece tightly and to block the central hole. Furthermore, a battery snap can be composed of two cylindrical terminal rivets, an insulation piece, a male engaging post, a female engaging post and a covering band.

  • Patent number: 6442832
    Abstract: A preferred method for coupling a transmission line to a circuit board includes the steps of: providing a circuit board with a first side and an opposing second side; dispensing solder upon the first side of the circuit board; providing a first coupler having a conductive lead portion and a ductile conductive tube portion extending from the conductive lead portion; engaging the conductive lead portion with the solder dispensed upon the first side of the circuit board; heating the circuit board, the solder and the conductive lead portion so that the solder reflows, thereby securing the first coupler to the first side of the circuit board; inserting an extremity of the first conductor into the ductile conductive tube portion; and crimping the ductile conductive tube portion so as to provide crimped retention of the first conductor therein. Circuit boards, devices and systems also are provided.

  • Patent number: 6332814
    Abstract: The present invention aims to provide a crimp connector wherein a crimp contact inserted in a connector housing 11 can surely be fixed to the proper position and thereby contact reliability can be enhanced in the case of being connected with a coupling connector. According to the crimp connector 10 of the present invention, since a protrusion 14 formed on the crimp contact 13 is bent after having inserted the crimp contact into a contact slot 12, the crimp contact can be surely fixed to the proper position. Therefore, not only can contact reliability be enhanced in the case of being connected with a coupling connector, but also a misoperation can be excluded during crimp-connecting an electric wire W with a crimp punch.

  • Patent number: 5731663
    Abstract: A variable power lamp control adapter is provided having a novel, different, and a lower cost construction method than that used in prior art lamp control devices. The circuit construction is achieved by utilization of the Surface Mount Technology disciplines of Polymer Thick Film and Chip on Board technologies. The adapter circuitry is constructed and held on a uniquely dissimilar type of substrate than that used in prior art, and assembled into housings that contain unique interengaging mating parts for a more rapid assembly process than the assembly processes used in prior art construction. In the present invention an overall improvement in the organization, arrangement of all componets, housings and assembly is achieved for a reliable power control operation.

  • Patent number: 5634813
    Abstract: An electrical terminal is adapted for use with an electrical conductor. The terminal has a terminating portion with a generally U-shaped cross-section having a web and a pair of sidewalls extending from two opposite longitudinal edges of the web. The sidewalls are generally trapezoidally shaped with relatively wide bases, joined to the longitudinal edges of the web, and relatively narrow tips. The bases are transversely aligned across the web. The tips are offset across the web so that the tips are spaced longitudinally of the web. Therefore, the tips will bypass each other when crimped toward each other to terminate the electrical conductor, all within the longitudinal confines of the bases of the sidewalls.

    Abstract: A system for fixing a prong (100) into a wall transformer housing (200) has a slot (202) through the wall into which the prong is mechanically inserted and fastened, rather than molded into place. The prong includes a body portion (101) for insertion into a wall socket, a neck portion (102) narrower than the body that is inserted into the housing slot, a head portion (104) that protrudes into the housing after the prong neck is inserted, and a twist portion (103) between the neck portion and the head portion having a reduced cross section so that the head can twist on the neck. The prong is inserted into the slot until the shoulder (the discontinuity of the neck and body cross sections) abuts the outer surface (212), the head may be twisted relative to the neck so that the chin (the underside of the head portion) rests on the inner surface. The neck portion is held firmly within the slot between the shoulder and the chin.

  • Patent number: 5562507
    Abstract: A two-layer multi-wire connecting socket structure is disclosed. It comprises a housing, a socket body, a plurality of pin seats arranged as an upper layer and a lower layer, and a pin package lid. The socket body has a plurality of through-holes arranged as an upper row and a lower row for receiving the upper layer and lower layer pin seats, respectively. The pin seat is formed as a generally L-shaped plastic member with a plurality of pins embedded therein. For each of the pins, one end thereof is bent to form a slanting terminal for contacting with a plug, and another end thereof is projecting outside of the plastic member for engaging with a PC board. The pin package lid covers one side of the socket body to allow the projecting pins to be securely spaced and aligned. The connecting socket structure so disclosed has the advantage of achieving smooth operation when a socket is inserted into a PC board. The two-layer structure also saves space on the PC board.
