Definitions

  • the invention relates to an electrical receptacle, apparatus according to the generic part of claim 1.
  • An apparatus of this kind is described in EP-A-268 364.
  • receptacle units are conventionally mounted in stationary walls or, alternatively, in the case of modern and modular office furniture systems, in moveable wall panels or even within work surfaces.
  • Devices to be electrically energized often comprise receptacle plugs having two or more prongs or blade terminals adapted to be conductively engaged within the female receptacles.
  • the prongs or blade terminals are conventionally referred to by the colloquial terms "male" plugs, prongs, blades or terminals.
  • the receptacle plugs are typically interconnected to the circuitry of the device so as to be energized by wires extending through flexible insulative cords or the like.
  • male/female electrical interconnection configuration to provide removable or releasable conductive engagement is utilized in a myriad of electrical connector arrangements.
  • male/female interconnection configurations are also utilized internally in electrical devices such as computers and associated peripherals.
  • male/female electrical interconnection arrangements are also utilized in a number of other applications, such as internal circuit wiring for electrical apparatus of modular office systems and the like.
  • one of the pairs of contact members may engage the edge surfaces of the tab contact.
  • the edge surfaces of the tab contact are typically the surface edges formed when the contact is made by stamping a sheet of conductive material. The surfaces are often rough in comparison with the planar rolled or formed surface of the sheet, and thus have a lower contact reliability. Accordingly, these contact members may not provide a reliable electrical connection, and a greater insertion force may be required at the time of insertion.
  • US-A-4 795 379 describes a receptacle contact having opposed leaf spring members formed by two parallel plates linked through a U-shaped portion extending between adjacent sides of the leaf spring members.
  • the leaf spring members include first spring arms and second spring arms formed integrally with the spring members.
  • the first spring arms and second spring arms are opposed to each other, and outer contact and inner contact members are formed at the free ends of the spring arms, which are also opposed to each other. Additional contact members are located to the rear of the first set of contact members.
  • the spring arms extend side by side from the leaf spring members, with the outer contact members being slightly twice the width of the inner contact members.
  • the contact members are arcuate to facilitate insertion of a tab contact therebetween.
  • the receptacle contact is formed by stamping from a suitable metal sheet having the desirable conductive and spring characteristics.
  • the stamping process is performed by shaping the metal sheet in an appropriate configuration, and then folding the spring arms to the shape required, while folding another portion into a U-shape.
  • the tip of a tab contact can be inserted into the space between the outer contact members opposed to each other at the front portion of the receptacle contact.
  • upper and lower surfaces of the contact are brought into a wiping engagement with the outer contact members. Accordingly, foreign matter on upper and lower surfaces of the contact is removed.
  • the upper and lower surfaces which have been cleaned by the outer contact members are also wipingly engaged by the inner contact members.
  • the outer contact members and inner contact members are in electrical engagement with upper and lower planar surfaces of the tab contact, and not with side surfaces which may comprise the cut edge surfaces of the contact. Accordingly, this decreases the force needed to insert the contact into the receptacle contact, thereby improving reliability of electrical connection.
  • the length of the spring arms which provide the contact force created between the outer contact members and the tab contact is longer than the length of the spring arms which provide the contact force between inner contact members and the tab contact. Accordingly, the insertion force is reduced by reducing the contact force created between the tab contact and the outer contact members, which clean the upper and lower surfaces of the tab contact. In this manner, the initial insertion force of the tab contact within the outer contact members is less than the insertion force of the inner contact members.
  • EP-A-268364 discloses an electrical connector having a connector adapted to engage a tap of an electrode. This contact arrangement is specifically to be used in generating electrocardiograms.
  • the connector includes a box-like housing, with a clamping member positioned within the housing.
  • the housing includes a front opening, with an upper jaw and a lower jaw positioned adjacent the opening.
  • the housing includes a base adapted to support the clamping member.
  • a roof of the housing includes an open slot.
  • a slide plate is also positioned within the housing.
  • a "finger-movable" member is defined, along with the slide plate, as comprising a slide actuator.
  • the slide plate is configured to slide on or beneath the surface of the roof.
  • the finger movable member rides in the open slot.
  • the problem to be solved by the invention is to provide an electrical receptacle apparatus in which no separate closure device is needed to lock two terminals together and which realizes a sliding contact but no scraping contact with the surface of the electrode blade.
  • an electrical receptacle apparatus includes at least one electrical receptacle adapted to conductively engage a blade terminal or the like.
  • the electrical receptacle includes an upper means extending forwardly, with a lower surface having at least first, second and third upper contact locations formed thereon.
  • Lower means are provided which extend forwardly and are conductively interconnected to and positioned substantially directly below the upper means.
  • the lower means include an upper surface with at least first, second and third lower contact locations formed thereon.
  • the receptacle is sized and configured so that the blade terminal is insertable between the upper means and the lower means.
  • the blade terminal is adapted to conductively contact the receptacle at the first, second and third upper and lower contact locations, so as to form at least six conductive electrical contact locations with the receptacle.
  • the blade terminal in insertable between the upper means and the lower means so as to form the conductively electrical contact locations without requiring manual manipulation of any component of the apparatus to maintain conductive contact pressure.
  • first, second and third upper contact locations are formed substantially within a single upper plane, and form a triangular configuration within the upper plane.
  • the first, second and third lower contact locations are formed substantially within a single lower plane, and form a triangular configuration within the lower plane.
  • the upper means includes at least one pair of upper lateral arms extending forwardly.
  • An upper bridge portion is positioned transversely across forward portions of the upper lateral arms, and conductively interconnects the upper lateral arms.
  • the upper bridge portion and the upper lateral arms form an upper spatial area.
  • Upper cantilever means are positioned substantially within the upper spatial area, and have an arcuate shape forming the first upper contact location thereon.
  • the second and third upper contact locations are formed at interconnections of the upper bridge portion and the upper lateral arms.
  • the lower surface of the upper means is formed of a lower surface of the upper cantilever means and lower surfaces of the upper bridge portion and upper lateral arms.
  • the lower means includes at least one pair of lower lateral arms extending forwardly.
  • a lower bridge portion is positioned transversely across forward portions of the lower lateral arms, and conductively interconnects the lower lateral arms.
  • the lower bridge portion and the lower lateral arms form a lower spatial area.
  • Lower cantilever means are positioned substantially within the lower spatial area, and have an arcuate shape forming the first lower contact location thereon.
  • the second and third lower contact locations are formed at interconnections of the lower bridge portion and the lower lateral arms.
  • the upper surface of the lower means is formed of an upper surface of the lower cantilever means and upper surfaces of the lower bridge portion and lower lateral arms.
  • the receptacle apparatus can comprise four of the electrical receptacles.
  • the apparatus can include a connecting beam central to and symmetrically located relative to the four receptacles.
  • the connecting beam can be rectangular in configuration and integrally connected to each of a pair of secondary connecting portions through a pair of U-shaped connecting portions formed at ends of the connecting beam.

  • a contact surface or edge 142 is formed at the interface between the integrally connected rear upwardly angled portion 136 and forward downwardly angled portion 138 of the lower cantilever members 130.
  • the opposing upper and lower cantilever members 110, 112 and the opposing inner cantilever members 128, 130 are flexible and resilient in nature so as to be appropriately flexed when a male blade terminal (illustrated in FIGS. 7-9) is inserted between the opposing cantilever members.
  • the contact surfaces 122 and 140 associated with the upper cantilever member 110 and the upper cantilever member 128 form a triangular contact surface configuration with the male blade terminal.
  • the contact surfaces 124 and 142 form an opposing triangular contact surface configuration, thereby providing six points of contact between the electrical receptacles 102, 104, 106 and 108 and the inserted male blade terminal.
  • This triangular configuration provides a substantial stabilizing effect to the interconnection between the male blade terminal and the electrical receptacles, while correspondingly providing six points of contact.

These tabs 156 provide a means for controlling positioning of the "boxes" formed by the surfaces of the connecting beam 144, secondary connecting portions 146 and U-shaped connecting portions 148.
  • the use of the electrical contact unit 100 with corresponding insertion of a male blade terminal 158 will now be described with respect to FIGS. 7-9.

  • four receptacles are provided with the necessity of only a single wire crimp configuration in an integral terminal, thereby providing an efficient use of space within a connector system. Still further, the triangular positioning of the three locations of contact on each of the upper and lower surfaces of the male blade terminal provide a substantially "steady" platform for the male blade terminal 158.
  • the electrical connector unit 100 can be formed from a suitable metal sheet by means of stamping and forming the unit 100, with the sheet having the appropriate conductive and spring and resiliency characteristics.
  • stamping process can be achieved by utilizing a suitably formed metal sheet, and then folding over the elements forming the upper cantilever members 110 and the secondary connecting portions 146.
