  • Patent number: 5173063
    Abstract: An electrical connector includes a dielectric housing including a transverse body section and a shroud portion extending forwardly therefrom and defining a cavity, an array of pin contact members extending forwardly of the body section and within the cavity and at least one pair of closely spaced elongate members within the cavity. The elongate members extend to respective leading ends forwardly beyond the leading edge of the shroud portion and cooperate with the shroud portion and with each other to disallow inadvertent entry of a human finger into the cavity proximate pin contacts adjacent the elongate members. The pair of elongate members further provide aligning and keying means for the connector.

  • Patent number: 5158471
    Abstract: A power connector for interconnecting power between printed circuit boards (12, 24) includes plug and receptacle contacts (40, 70) linked to signal connector halves (16, 28) alos mounted on the circuit boards such that the plug and receptacle contacts intermate along a given axis as the connector halves are intermated. The receptacle contact (70) includes an array of resilient contact fingers (80-82) spaced apart and staggered to engage the plug contact (40) upon mating along the given axis at given points to reduce insertion forces, preclude undue wear of the plug contact from repeated engagements while carrying sufficient current to effect a power transfer from one board to another board. The contacts further include a plurality of posts (48, 74, 76) spaced apart to distribute current to the thin conductive traces of boards to preclude undue resistance heating of such traces in the circuits defined thereby.

  • Patent number: 5139426
    Abstract: An adjunct electrical connector (44-60) includes a mechanical line (52) added to a signal connector half (34) to increase power transfer between circuit boards (12, 24). The power connector includes contacts of a given cross-section to carry a given current with the contacts having a plurality of posts (50, 70) spaced apart and of a lesser cross-section to carry a fraction of the given current so as to distribute such current to thin conductive traces (32) on the said board half with said post being on the centers of holes in said printed circuit board (24).

  • Patent number: 4975066
    Abstract: A coaxial contact element for use in receptacle connectors of the type used with printed circuit cards and the like. More particularly the contact element includes an inner contact for being electrically mated with a center contact of a post and an outer contact for being electrically mated with outer contacts of the post. A dielectric spacer electrically isolates the inner and outer contacts of the contact element.

  • Patent number: 4966557
    Abstract: An improved electrical contact element for use in connector housings. More particularly, the contact element includes a U-shaped retention section having one resilient leg extending obliquely outwardly. Further included is a resilient web in between and connecting the forward termination section and retention section to provide a degree of independent movement of the former relative to the latter.

  • Patent number: 4952172
    Abstract: A stiffener device for use with electrical connectors. More particularly, the stiffener device includes a rigid L-shaped member having a groove in which an electrical connector is slidingly received and locking clips which are attached to the connector and frictionally received in a channel in the L-shaped member to prevent relative movement between the member and connector.

  • Patent number: 4671584
    Abstract: An electrical power connector for conducting electrical power from a power bus bar to a circuit card. More particularly, the connector includes contact elements having tab terminal receiving receptacles positioned in a dielectric housing in a staggered arrangement so that the forces requires to insert tab terminals into the receptacles are distributed. Further, the terminal-receiving space in each receptacle is defined by a stationary member on one side and dual side-by-side spring-biased members on the other side so that the force required to insert a tab terminal therein is initially incremental.

  • Patent number: 4653826
    Abstract: A high current power connector has contact elements defining a pin receiving opening. The contact elements are spring loaded inwardly to increase the contact force between each contact element and a pin. The connector also has the capability for the contact members to float and to realign themselves if the pin and contact elements are misaligned.

  • Patent number: 4637677
    Abstract: An electrical connector for electrically interconnecting flat terminals known as tabs. The contact units are loosely positioned in a housing but yet preloaded to provide wiping action on the inserting tabs terminals. The spring members of the contact units provide two stage insertion forces with the first stage being a low force and the second stage substantially higher.

  • Patent number: 4332849
    Abstract: The present invention relates to a device which is used to repair a damaged insulating jacket on an electrical cable. The device is shrunk down around the cable without the use of heat to provide an impervious, protective covering. More particularly, the invention includes a sheet or sleeve which is elongated and held in that state by removable support struts. After covering the damaged area of the cable jacket, the struts are withdrawn to allow the sheet or sleeve to shrink down around the cable.
