  • Patent number: 5545054
    Abstract: An electrical connector includes a dielectric housing having a through axial passage for receiving therein an electrical terminal. A cover is hingedly connected to the housing for movement from an open position to a closed position, with the cover and the housing having respective juxtaposed walls bounding at least one lateral side of the passage when the cover is in its closed position. Complementary laterally engaging latches are provided between the juxtaposed walls to hold the cover in its closed position. The wall of the cover is juxtaposed inside the wall of the housing in a lateral direction. Therefore, lateral forces on the terminal biases the wall of the cover outwardly toward the wall of the housing to ensure engagement of the laterally engaging latches.

    Abstract: An electrical connector assembly includes a housing fabricated of a first metal material and having at least one integral pin projecting from a face thereof. A flat flexible circuit is mounted against the face of the housing and includes a ground plane on a side thereof facing the housing. The circuit has a hole for receiving the integral pin of the housing. The ground plane is of a second metal material different from that of the housing.

  • Patent number: 5281168
    Abstract: An electrical connector assembly includes a terminal position assurance system. The assembly includes an elongated dielectric housing having a plurality of terminal-receiving cavities extending transversely of the housing. A plurality of terminals are insertable into the cavities. A passageway extends longitudinally of the housing. An elongated terminal position assurance member is insertable into the passageway and movable between a preloaded position and a loaded position. The terminal position assurance member prevents mating of a complementary connector with the connector assembly when the member is in its preloaded position.

  • Patent number: 5277610
    Abstract: A sealing system is provided between an electrical connector assembly and another connector component, panel or the like. The connector assembly includes a housing having a mating end with a seal-receiving channel and a resilient seal received in the channel. The seal includes a sealing groove having a given width and a given depth. The connector component includes a sealing lip insertable into the sealing groove when the connector assembly and the connector component are mated along a mating axis. The sealing lip has a width greater than the width of the sealing groove and a length relative to the depth of the sealing groove such that the lip is spaced from the bottom of the groove when the connector assembly and the connector component are in mated condition. Therefore, only sealing forces normal to the mating axis are effected between the sealing lip and the sealing groove.

  • Patent number: 5276752
    Abstract: A fiber optic connector system includes male and female mating connectors for interconnecting a pair of optical fibers each having a central core and an outer jacket. Each connector includes a housing adapted for receiving an end of one of the optical fibers and for mating with the other connector. Each connector housing is a plastic structure overmolded about the outer jacket of its respective optical fiber in an area at the end of the fiber. The outer jacket of the fiber has circumferential grooves into which the overmolded material of the connector housing extends for axially retaining the overmolded housing on the fiber. A band-like locking clip surrounds telescoped portions of the male and female connectors. The locking clip has a radially inwardly projecting locking tab extending into aligned apertures in the telescoped mating portions when the connectors are mated.

  • Patent number: 5116236
    Abstract: An electrical connector is provided with a transversely aligned terminal position assurance (TPA) component that is slidably insertable into a transverse keyway in the connector housing. The TPA component includes a plurality of flexing primary latches and a corresponding plurality of static secondary locks. The flexing primary latches are disposed to align with the terminal receiving cavities of the housing when the TPA component is in a pre-load position. The terminals can be inserted into the housing with the TPA component in this pre-load position such that the flexing primary latches at least temporarily retain the terminals in the housing. Upon complete insertion of all terminals the TPA component is indexed transversely into a final locked position such that the static secondary locks thereof positively engage each terminal to ensure complete insertion. A symmetrical front mating seal is configured to be held in the housing by suction to prevent separation during unmating.

  • Patent number: 5017162
    Abstract: A sealed electrical connector assembly is provided for wire-to-wire electrical connections. The assembly includes a pair of mateable electrical connectors each of which includes a plurality of terminal receiving cavities extending therethrough. Each terminal receiving cavity preferably includes a static locking projection and a dynamic terminal positioning beam which deflects during insertion of the corresponding terminal and which resiliently returns to an undeflected condition for locking the terminal in the housing after complete insertion. A TPA component is mounted to the rear of each housing prior to insertion of the terminal. The TPA component includes terminal receiving apertures which function to rotationally align each terminal for efficient full seating in the corresponding terminal receiving cavity. Positive assurance of full terminal seating is achieved by advancing the TPA component from a first position into a second locked position.
