Definitions

  • This invention relates to connectors for connecting conductors of coaxially shielded cables to non-coaxial male contacts.
  • Coaxially shielded cables are well known as the highest fidelity signal wiring for digital signals and analog signals throughout the microwave frequency range.
  • the advent of large scale integrated circuits has increased the density and complexity of electronic circuitry to the point where coaxially shielded cables are often required for interconnection in high density applications.
  • the usefulness of coaxially shielded cables has been limited by cumbersome and time consuming connection methods.
  • GB-A-1558383 (equivalent to F-R-A-2334267) discloses a connector in which coaxial cable is wired to two, parallel sockets for connection with two adjacent male pins in a row of such pins. Two such connectors may share a male pin as a common earth connection, but only if the connectors are stacked one over the other; and no more than two connectors can share the common pin because they occupy both neighbouring pins in the row and prevent the attachment of a third connector to the common pin.
  • This connector is therefore not suitable for packaging with a high density of connections, since it is not possible to arrange for a common earth connection for multiple connectors, and stacking is required for any sharing of a pin.
  • a connector assembly for connecting conductors of a coaxially-shielded cable to a selected one of a row of male contacts
  • said connector assembly comprising: a connector having a first, inner contact, permanently connectable electrically and mechanically to a first, inner conductor of a cable, and removably connectable electrically and mechanically to the said selected male contact, an electrically-insulating element, surrounding the first, inner contact, and an outermost, rectangular-section contact surrounding the insulating element, electrically and mechanically connectable to an outer conductor of the cable, and fastenable to an outermost jacket of the cable, and characterised by an auxiliary contact which may be disposed lengthwise along the said row, to provide a mechanical and electrical interconnection between an outer conductive face of the outermost contact and another one of said row of male contacts.
  • the auxiliary contact provides an electrical connection, for example an earth connection, between the outer conductors of one or more such connectors and a male pin remote from the connector.
  • the remote pin may then act as a common earth connection for multiple connectors, and there is no need for any stacking of the connectors over the pins.
  • the auxiliary contact is, in one preferred form, a square-wave-shaped springy metal strip which, in use, is disposed among the male pins, and around the connectors thereon, in an interlocking manner.
  • a coaxial connector assembly embodying the present invention is described with reference to Figures 1 and 2 wherein like elements have like numbers.
  • a first inner contact 10 comprising a standard contact which is fully compatible with the standard, non-coaxial round pin or square post male contacts 80 commonly used in packaging electronic circuitry is connected to a first inner conductor of a coaxial cable at junction 91.
  • the standard square post male contacts can be of lengths varying from approximately 0.2 inch (0,5 cm) to approximately 1 inch (2.5 cm) and transverse facial dimensions of 0.025 inch (0.064 cm) square.
  • Round pin male contacts are typically between .020 inch (0.051 cm) and .035 inch (0.089 cm) in diameter.
  • An electrically insulating medium 20 surrounds the first inner contact 10 and extends axially along the surface of the first inner contact 10.
  • the insulating medium 20 is surrounded by an outermost contact 30 to which is connected the outer conductor 92 of a coaxial cable 100.
  • the axes of the first inner contact 10 and the outermost contact 30 are substantially mutually coincident or parallel.
  • the outermost contact 30 is a hollow rectangular-section solid having a transverse face of which the dimensions of the side extending along the row of contacts 80 is slightly smaller than the centre-to-centre distance of the contacts 80. This centre-to-centre distance can be as small as 0.100 inch (0.254 cm).
  • An auxiliary contact 40 is installed lengthwise among a row of standard male contacts 80 by connecting a female connector or socket 50 of contact 40 onto a standard male contact 80 or by connecting two spaced sockets 50 of contact 40 onto two standard male contacts 80 spaced apart along a row of male contacts 80.
  • the auxiliary contact 40 provides a mechanical and an electrical interconnection between an unoccupied male contact 80 and the outermost contact 30 of at least one connector.
  • the auxiliary contact 40 can be made from a strip of any highly conductive material.
  • the shape of the auxiliary contact 40 is such that a portion of the auxiliary contact 40 contacts a portion of an outer conductive face of the outermost contact 30 whenever an outermost contact 30 is connected to one of the standard male contacts disposed in a row.
  • the auxiliary contact 40 can be shaped as a square wave, made of springy metal strip and installed among a row of standard male contacts 80 such that, whenever an outermost contact 30 is connected to one of the standard male contacts, three axial faces of that outermost contact 30 contact portions of the auxiliary contact 40.
  • the half wavelength of the aquare wave should correspond with the spacing between adjacent male contacts 80.
  • other shapes are possible which will also provide sufficient contact between the auxiliary contact 40 and an outermost contact 30.
  • the outermost contact 30 can be selectively supplied with an electrically-insulating coating to leave exposed only portions of the outermost contact 30 which serve as electrical contact points.
  • auxiliary contact 40 The advantage of the auxiliary contact 40 is that the outer conductors of several coaxial cables can be efficiently connected together and to the electronic circuitry. This prevents wasting space that occurs if the outer conductors are separately tied together or if each other conductor is separately tied to the electronic circuitry.
  • the outer conductors can all be tied to ground by connecting the socket 50 of the auxiliary contact 40 to a standard male contact which is grounded. This eliminates the need for separately grounding each outer conductor.
  • a modification of this embodiment can be achieved by selectively applying an electrically insulating coating to the outermost contact 30 and to the auxiliary contact 40 to leave said contacts exposed substantially only at their interface.
  • a second inner contact (not shown) is connected to a second inner conductor of a coaxial cable and is compatible with the standard male contacts.
  • the second inner contact must be electrically insulated from both the first inner contact 10 and the outermost contact 30 and must be disposed so that the distance from the centre of the second inner contact to the centre of the first inner contact 10 is equal to the centre-to-centre distance of the male pins 80.
  • the shape of the outermost contact 30 and the auxiliary contact 40 must be appropriately modified.
