Definitions

  • This invention relates to terminals for video pair cables; and more especially to terminals that are mounted on a plate of a terminal rack.
  • Another object is to provide a terminal construction .of the character indicated which is particularly convenient to connect and assemble with resulting saving in time and cost.
  • FIGURE 1 is a diagrammatic elevation, partly broken away and in section, of a terminal assembly construction connected with a cable stub;
  • FIGURE 2 is a greatly enlarged sectional view taken on the line 22 of FIGURE 1 and showing the connection of an individual video pair with a receptacle of the terminal assembly;
  • FIGURE 3 is a sectional view on the line 3-3 of FIGURE 2.
  • FIGURE 1 shows a cable stub 10 which includes a lead sheath 12 covering four video pairs 14 which are insulated from the lead sheath by insulation 16.
  • the lead sheath 12 of the cable stub is connected to a hollow element or manifold 20 by solder 22.
  • Each video pair 14 is connected to a connector receptacle 26 by passing the pair through a copper tubing 28 which ends in a housing 30 connected to a mounting plate 32 of a terminal rack.
  • FIGURE 2 shows one of the copper tubes 28 connected with one of the housings 30 by a connection 36 Patented Apr. 2, 1968 which provides a rigid and air tight connection for the tube with the housing.
  • the video pair 14, which extends through the tube 28, consists of two conductors 38 and 39, insulated from each other by insulation 40, and insulated from shielding 42 which is preferably a tape surrounding the insulated conductors 38 and 39 outside of their insulation 40.
  • the video pair 14 also includes an uninsulated conductor 46 which is connected to the video pair shielding at the point 48 (FIGURE 1).
  • the conductors 38, 39 and 46 pass through a hermetic terminal seal 50 and are soldered at points 52 to the terminal seal 50.
  • This hermetic terminal seal 50 seats against a shoulder 58 in the housing 30'.
  • the seal 50 is a partition made mostly of electrical insulating material but with metal inserts for soldering to the conductors 38, 39 and 40.
  • the seal 50 rests in the housing 30 and there is an O-ring 60 held down against the shoulder 58 by a washer 62 which is pressed downward by a retainer 64 threaded into the upper end of the housing 30.
  • the conductors 38 and 39 are terminated at female pins 66 and '68, respectively, of the receptacle 26.
  • the conductor 46 is connected with a copper ring 70 by a connector 72.
  • the housing 30 is connected to the plate 32 by angularly spaced screws 65.
  • the receptacle 26 has a metal outer shell 74, and is attached to the mounting plate 32 by screws 76 which extend through a flange 78- that is an integral part of the lower end of the receptacle 26, and through an insulating gasket 80 into threaded openings 82 in the mounting plate 32. Although the screws 76 fit the threads in the .opening 82, these screws 76 are substantially smaller in diameter than the openings which the screws pass through in the flange 78 and the gasket 80. There are electrical insulating bushings 86 with integral flanges 88 at their upper ends surrounding the screws 76 and insulating the screws 76 from the flange 78.
  • the video pair shield is continued through the receptacle 26 by means of the copper ring 70 which is in physical contact with the metal of the receptacle 26; but the video pair shield is isolated from the mounting plate 32 by the insulating gasket 80 and by the bushings 86 with their flanges 88 interposed between the screws 76 and the flange 78 of the receptacle 26.
  • Grounding of the terminal rack grounds the mounting plate 32 which is a part of the terminal rack and this grounds the lead sheath 12 through the housing 30, tubing 28 and manifold assembly 20 (FIGURE 1). If the video pair shield is to be grounded on the mounting plate 32, this can be accomplished by merely removing the flanged bushings 86 from the assembly so that the shoulders at the heads of the screws 76 can contact directly with the top surface of the metal flange 78 of the receptacle 26.
  • a video pair cable terminal construction including a housing for receiving the end of a video pair cable which has a grounding conductor and insulated conductors with shielding around the insulated conductors, a receptacle with quick detachable terminal means for connection to the ends of the insulated conductors beyond the insulation, fastening means for connecting the housing to a mounting plate, other fastening means for connecting the receptacle with the mounting plate, means for electrically insulating the receptacle from the mounting plate and means for connecting the receptacle with the grounding conductor of the cable.
  • the video pair cable terminal construction described in claim 1 characterized by a mounting plate between the receptacle and the housing, the housing being in electrical contact with the mounting plate, an electrical insulating gasket between the receptacle and the mounting plate, and other insulation between the receptacle and said other fastening means for connecting the receptacle with the mounting plate.
  • the video pair cable terminal construction described in claim 2 characterized by means grounding the mounting plate, the means for connecting the receptacle with the grounding conductor of the cable being an electrically conductive ring clamped between the receptacle and the insulating gasket and also a conductor for connecting the ring with the grounding conductor of the cable.
  • the video pair cable terminal construction described in claim 1 characterized by a housing including a sealing partition through which all of the conductors extend in insulated relation to one another, and means hermetically sealing the partition around the conductors and between the partition and the inside wall of the housing.
  • the video pair cable construction described in claim 1 characterized by a video pair cable extending into the housing and having two insulated conductors with shielding outside the insulation, and a grounding conductor that extends along the length of the insulated conductors and adjacent thereto, the shielding being connected with said grounding conductor and the receptacle having an outer metal housing which is also connected with said grounding conductor.
  • the video pair cable construction described in claim 2 characterized by a video pair cable having at least two insulated conductors with shielding around the outside of the insulation and a grounding conductor that extends along the length of the insulated conductors and adjacent thereto, another covering layer outside of the insulated and grounding conductors, a hollow element into which the cable extends, the outside layer of the cable terminating in said hollow element and the insulated conductors and grounding conductor of the cable continuing beyond said hollow element to said housing, and tubing leading from the hollow element and through which the conductors of the cable extend between said hollow element and the housing, the shielding being electrically insulated from the hollow element and the tubing.
