  • Patent number: 6932656
    Abstract: A connector with improved structure, adapted for connecting a signal plug, is mainly comprised of a body, a pin plate, and a cap. Wherein, a plurality of recesses are arranged over the body, side of which has at least one gap, and a plurality of pins are arranged over the pin plate, side of which also has at least one protrusion. When the body and the pin plate are connected, the protrusion and the gap are inter-wedged, and the pin is abutted against one side of the recess. The cap of the present embodiment is connected pivotally over the body and may be rotated with an angle, so a signal plug may be inserted into the space formed by both the body and the cap with a slant angle and be restricted by the cap without dropping off.

The housing comprises an elongate slot formed between opposite side walls thereof for receiving a daughter board, a plurality of receiving passageways defined in each side wall for retaining contacts therein, a pair of cutouts transversely defined in a mating face of the housing, and a projection transversely formed between the side walls. The daughter board defines a pair of notches corresponding to one of the cutouts and the projection of the card edge connector. The switch key can transmit information to the mother board by electrical contact between a conductive membrane disposed on the switch key and the corresponding contacts received in the passageways below the corresponding cutout of the housing.

  • Patent number: 6159052
    Abstract: An electrical connector adapted to be mounted to a mother board, includes a casing defining a slot therein for receiving a daughter board and a plurality of pin pairs arranged in the slot for electrically engaging with the daughter board. The casing has a fixed member fixed in the slot and a switch key selectively fit into the slot at two locations corresponding to a 3.3V PCI connector and a 5V PCI connector. Thus, the connector may be selectively configured to be either a 3.3V PCI connector or a 5V PCI connector by setting the position of the switch key. The insertion of the switch key into the slot changes the spatial relationship between a pair of pins thereby transmitting a signal to the mother board for selecting the electrical voltage supplied to the connector corresponding to the configuration of the connector.

  • Patent number: 6142592
    Abstract: An instrument system having at least one instrument disposed in a housing (1) the housing is to be mounted detachably on a support (3) and a user is to set a coding for each system module comprising instrument and support. Grooves (23 or 27) are provided in the support (3) for taking up coding pins (31). In the assembled state the grooves (23) of the support form groove pairs with the grooves (27). The inner spaces of the grooves of a groove pair together form an interstice for accommodating just one coding pin (31). This is fixed in either the groove (27) or in the groove (23). In this way the assignment of a housing (1) to a support (3) is established through the positions of the coding pins (31).

  • Patent number: 6095870
    Abstract: A structure for preventing false engagement of a connecting seat with a base is disclosed, in which one or more stoppers in different positions are installed in spacing sections between each of the two adjacent jacks, at the top ends of the spacing sections of the base. Longitudinal notches corresponding to the stoppers are formed on the top edge of the spacers that separate respective pairs of the plurality of receiving holes of the connecting seat. When the base and the connecting seat are to be engaged, if the stopper is aligned with the notch, they can be engaged tightly. If it is not aligned with the notch, the connecting seat and base can not be engaged.

  • Patent number: 6069992
    Abstract: A system includes mateable connectors (12, 14) with mateable optic fiber termini, which provides for precision alignment of the termini and which facilitates installation of an insert whose front end must be of rectangular shape. Two mating sets of optic fiber termini (30, 32) are precisely aligned by a pair of pin-receiving alignment holes (44, 46) in one connector and a pair of pins (40, 42) projecting from the other connector, wherein a first (40) of the alignment pins is precisely cylindrical and fits closely in the first hole, and a second (42) of the pins is also precisely cylindrical but fits into a hole (46) that is elongated in a direction toward and away from the first hole. A front portion (110) of an insert is of largely rectangular cross-section, while the rear portion (112) of the insert is of largely circular cross-section to enable retention by a circular retainer clip (120) and to provide threads (122) for threading into a backshell.

  • Patent number: 6048229
    Abstract: An electrical rectangular connector having an expanded range on the lower limit of the environment resisting wire sealing webs, a dielectric hard face socket insert to detect splayed or bent pin contacts, a controlled configuration on the contact retention clips which provides easy insertion and removal on the contacts. Additionally, the modular insert construction of the connector allows flexibility to the wiring system, meaning, the connector can have a signal, power, coaxial or twinaxial or combination circuitry and also a bayonet coupling mechanism assembly using dowel pins and dual helical ramp grooves to retrin the connector halves in the coupled condition. Consequently, a visual indicator consisting of an arrowhead opposite a marker labeled "HOME" provides assurance on a fully coupled plug and receptacle connector.
