The keys are used in pairs, one key at each end of the connector to prevent partial mating and the resulting potential damage. The keys are in diagonally opposite positions to prevent inadvertent partial mating along an edge of the connector. The keys are removable and replaceable so that keying configurations can be changed in the field.

This box comprises a movable part with foolproof means which may be moved transversely with respect to the axis of the ducting, between a first position in which the foolproof means cooperate with associated foolproof means on the ducting so as to allow connection of the box to the ducting and a second position making such connection impossible. Marks provided on the movable part make it possible to identify the conductors of the box for each of the two positions.

  • Patent number: 4895535
    Abstract: A system of keying of a panel mounted connector and a mating connector is provided where each of the connectors is of the type having forward and rearward thin walled metal shells clinched together about their flanged edges to retain a housing means therewithin, with the forward and rearward shells having adjacent apertured lateral flanges enabling mounting of either one of the connectors to a panel at an I/O port of an electronic apparatus by screw means. The keying system includes a pair of key members each securable to the front of the forward shell at a respective lateral flange, by the corresponding screw means extending through the apertures of the rearward and forward shell flanges and threaded into a threaded key member aperture. The key members may have octagonal cross-sections and are seated within correspondingly octagonally shaped flange apertures of the forward shell only, held against the front surface of the rearward shell.

  • Patent number: 4884975
    Abstract: A centering strip for plugging onto a backplane printed circuit board provided with contact blades accepts plugs in a housing opening and accepts contact blades through openings in a floor of the centering strip. In order to guarantee that the individual cable plugs are correctly plugged into the proper location on the centering strip and that the centering strip is not damaged when the plug is inserted into the housing opening, the centering strip is divided into a plurality of segments by transversely oriented partitions. The partitions have two sides on an upper half portion which forms a mechanical coding devices for the plugs to be accepted. The lower half of the partitions are provided with cavities for acceptance of contact blades. The depth of the cavities is dimensioned such that the centering strip is supported on the contact blades by a solid middle part located between the upper and lower half portions of the partitions.

  • Patent number: 4832619
    Abstract: A pin mounted support system for printed circuit cards and connectors includes a base portion having one or more bores for mounting upon the pins of the header and a guide surface portion that delimits the installed position of the printed circuit card or connector. Where the support is intended for use with a printed circuit board, the support includes a groove or track for accepting and supporting a lateral edge of the printed circuit board. Where the support is intended for use with a connector terminated cable, a keytab is provided with one or more bores for mating with the pins of the header to delimit the proper position of the connector. The connector is positioned between the keytabs and installed in its mated position. The supports are typically fabricated from a molded plastic and are easily removable from their support pins to allow convenient reconfiguring of the header.

  • Patent number: 4822305
    Abstract: A programmable keying system (51) for electrical connectors includes keys (56) which are supported within key-receiving passageways (61) in a connector (10) to cooperate with opposing keys in a complementary connector to ensure that the connector (10) will mate only with a connector with which it is intended to mate. The keys (56) are supported in the passageways (61) in a partially inserted, programmable first position in which they are loosely retained in the passageways (61) by first retention means, but are capable of being rotated to a selected orientation. After being oriented, the keys (56) are pushed fully into the passageways (61) to a locked second position in which they are locked in the passageways (61) in the selected orientation by second retention means. The keying system (51) permits connectors (10) to be shipped to a customer with the keys assembled thereto but with the keys unprogrammed such that they can be programmed in the field at a later time.

  • Patent number: 4820204
    Abstract: A modular electrical connector assembly consisting of a plurality of components which can be assembled in a number of different configurations is disclosed. Each connector consists of an outer body (100, 200) and an inner body (300, 400). The inner and outer bodies are separately and independently keyed and each mates with a corresponding inner or outer body in only one configuration. The inner body is keyed by providing distinct cross-sections for intermating posts (310) and cavities (410). The outer bodies (100, 200) are latched together by a plurality of collects (202) on one connector (200) which are held in engagement with a cylindrical ridge (130) on the other connector by a spring loaded shiftable sleeve (150). Keys (142) on one connector are received in keyslots (212), between adjacent collets (202) on the other connector. Conductors (30) in distinct and corresponding ordered arrays can be interconnected and the circuit patterns need not be changed in order to provide for connector modulatity.
