  • Patent number: 5116263
    Abstract: Terminals having rectangular post sections of very small dimension are secured in housing passageways of an electrical connector, which passageways are molded using core pins larger in dimension than said very small dimensioned terminal post sections, so that the oversized core pins are robust and endure repeated molding cycles. End sections of the core pins have the very small dimension of the terminal post sections and the paassageways have constricted end sections which precisely locate the terminal post section along the connector mating face. An increased terminal width at the insertion face creates an interference fit within the passageway for retention. The core pin has a strength rib along most of one side and the forward rib end is tapered to the reduced-dimension pin end section which results in a tapered passageway transition surface to eliminate terminal stubbing during insertion.

  • Patent number: 5064391
    Abstract: An electrical connector (20) is disclosed which includes a dielectric housing (24) having first and second contact receiving channels (40) with each channel defining a pair of side walls (154,156). A rib (158) on the housing separates the first and second channels (40) and extends between respective side walls (154,156) thereof. A first contact (22) is received in the first channel (40) with the first contact defining an axis (112) and having first and second side edges (100,102) on opposite sides of the axis. The first side edge (100) has a barb (108) extending therefrom away from the axis (112). The second side edge (102) has a barb (110) extending therefrom away from the axis (112) at a location spaced along the axis (112) a distance (122) from the barb (108) extending from the first side edge (100). The barb (108) extending from the first side edge (100) engages a side wall of the channel that forms the rib (158).

  • Patent number: 4936798
    Abstract: The housing, which is of circular cross section, defines a series of spaced, terminal-receiving cavities arranged in a ring about the axis of the housing. An annular terminal retainer is received in an annular recess in the housing, at the outer periphery of a ring of terminal cavities. The retainer is provided with radially inwardly projecting terminal retaining members. The retainer ring can be moved between a first position, in which the terminal-retaining members are clear of the cavities, to allow terminals to be inserted into the cavities and a second angular position in which each retaining member intersects a respective cavity to overlie a collar on the respective terminal therein so that it is locked in its cavity.

  • Patent number: 4804341
    Abstract: A connector housing is formed with two kinds of terminal passages for receiving therein two kinds of terminals each of which has an electrical contact portion, a conductive lead connecting portion and a transition portion between the electrical contact portion and the conductive lead connecting portion. The connector housing is also formed with a plurality of retainer passages for receiving therein retainer pins. The retainer passages are arranged so that each retainer passage passes through the intermediate portions of the terminal passages of each row and allow each retainer pins to engage the transition portions of the terminals of each row.

  • Patent number: 4802868
    Abstract: An improved contact spring connector strip of the type having a housing forming contact chambers and inlets, contact sets in the chambers, and a cover with passageways. The contact sets include springs, which engage stops formed in the inside wall of the housing and have a pair of spring clips, and push-in pins insertable between the clips. Flanges formed on the inside wall separate the clips and extend to ends tapered toward the cover, and have flange end portions with recesses which receive transverse tabs on the push-in pin to firmly support the push-in pin.

  • Patent number: 4772229
    Abstract: Connector plug comprises a housing having main body part and a separate terminal retaining member which retains the terminals in the cavities of the housing. The terminal retaining member extends into a recess which is between the ends of the main body of the housing and has retaining ears that prevent movement of the terminals from the cavities. The retaining member is releasably latched to the main body part of the housing by a latch arm that is contained within the main body part. An access opening is provided in the main body part of the housing to permit disengagement of the latch arm and removal of the terminal retainer part from the main body part. The connector is sealed and is relatively compact.

  • Patent number: 4695107
    Abstract: A novel integrated circuit socket provides splash-preventing capillary action improving half-round section pins that seat better by means of a conical longitudinal shape that wedges in holes in conventional printed circuit boards. The pins have P.C. board top-track contacting spurs at an upper portion that serve two purposes: they improve capillary action and they reduce bellying (i.e. flexing) of the I.C. socket during assembly to the P.C. Board. The invention provides improved visibility by co-action of transparent material of which the I.C. socket is made, with a plurality of Fresnel lenses molded in the bottom surface of the I.C. socket.

  • Patent number: 4674816
    Abstract: To reliably prevent ingress of moisture to a connection between an electrical connecting cable or line to an electrical apparatus within a housing, the conductors of the cable or line are externally surrounded by an insulating layer which is of such a material that it joins, by melting or chemical reaction with the material of a surrounding bushing or sleeve, which bushing or sleeve then can be secured in a wall of the apparatus, for example by a removable rubber ring (FIG. 2) or can be molded into the housing of an electrical apparatus, for example a sensor; preferably, the materials of the housing and of the plug or sleeve also join, either by melting together or by chemical reaction. For a melt connection, a thermoplastic such as polyamide is suitable; for reactive connection, a reactive thermosetting plastic, for example polyester imide, or epoxy may be used.
