Definitions

  • This invention generally relates to the art of connectors or terminals and, particularly, to a terminal and terminal assembly for terminating the shield of an insulated coaxial cable.
  • a typical shielded coaxial cable includes a center conductor core with a dielectric sheath therearound. An outer insulating jacket is provided, with the shield disposed between the dielectric sheath and the insulating jacket.
  • the shield is tubular and of a conductive braided material.
  • Terminals or terminal assemblies often are used to terminate the conductive shield of the coaxial cable. Typically, this is accomplished by a terminal with some form of crimp barrel or other means having teeth which pierce the outer insulating jacket and contact the strands of the braided shield. Many such teeth are required to provide an adequate contacting interface. The pressure against the braid by such teeth is quite random, and the combination affects the dielectric properties of the cable. Specifically, the cable impedance can be affected by such terminals, because the terminals often result in considerable deformation of the dielectric sheath about the center conductor.
  • the shield is terminated to ground and stringent limits are imposed on any disturbance of the cable impedance.
  • the present invention is directed to solving these problems and satisfying such a need.
  • An object, therefore, of the invention is to provide a new and improved terminal and terminal assembly for terminating a shield of a shielded insulated cable.
  • a shielded cable typically includes a conductor core with a dielectric sheath therearound.
  • An outer insulating jacket is provided, with the shield disposed between the dielectric sheath and the insulating jacket.
  • a terminal generally includes a pair of teeth movable toward each other in a direction generally tangentially of the dielectric sheath.
  • the teeth displace the outer insulating jacket and clamp a portion of the shield between the teeth without substantially disturbing the dielectric sheath.
  • the terminal is disclosed herein in a termination assembly which includes a dielectric housing having a receptacle for receiving the terminal.
  • the terminal includes two pairs of relatively movable teeth, with one pair on each opposite diametral side of the cable.
  • the terminal is fabricated of sheet metal material and includes a base portion in abutment with a fixed wall of the receptacle of the housing and a pressure portion movable toward the base portion.
  • One of the teeth in each pair thereof is on each of the base portion and the pressure portion of the terminal.
  • One or more deformable arms integrally join the base portion and the pressure portion of the terminal.
  • Another feature of the invention is the provision of complementary interengaging latch means between the housing and the movable pressure portion of the terminal to hold the pressure portion in an actuated position. This holds the teeth in their clamping positions to clamp a portion of the shield therebetween.
  • the invention is embodied in a termination assembly, generally designated 10, for terminating a shield 12 of a shielded insulated cable, such as a coaxial cable generally designated 14.
  • the termination assembly includes two components, namely a dielectric housing, generally designated 16, and a terminal, generally designated 18, received in the housing.
  • coaxial cable 14 is of a conventional structure and includes a center conductor core 20 with a dielectric sheath 22 therearound.
  • An outer insulating jacket 24 is provided, with shield 12 disposed between dielectric sheath 22 and insulating jacket 24.
  • Shield 12 is shown as a typical braided shield of conductive metal material.
  • terminal 18 is shown in Figure 1 in an open position projecting from the top of housing 16.
  • cable 14 can be inserted into an opening 26 in housing 16 in the direction of arrow "A" (Fig. 1).
  • pressure is applied to the terminal in the direction of arrow "B" (Fig. 2) which effectively collapses the terminal and terminates the shield, as will be described in greater detail hereinafter.
  • housing 16 includes a front wall 28, a rear wall 30, a bottom wall 32, a top wall 34 and a pair of side walls 36, all of which combine to form a generally rectangular receptacle, generally designated 38. Opening 26 for receiving cable 14 is formed in front wall 28. Access to receptacle 38 is provided by an opening 40 in top wall 34 and through which terminal 18 is mounted in the receptacle. A pair of holes 42 are formed through each side wall 36, for purposes to be described hereinafter. A saddle 44 is formed in the top of rear wall 30 and through which a connecting portion (not shown) of terminal 18 can extend.
  • FIG. 1 shows a pair of guide grooves 46 in rear wall 30.
  • the entire housing 16 is a unitary or one-piece structure molded of dielectric material such as plastic or the like.
  • terminal 18 includes a generally planar base portion 50 and a generally planar top or pressure portion 52 parallel to the base portion.
  • the entire terminal is stamped and formed of sheet metal material. Therefore, base portion 50 is interrupted lengthwise of the terminal by a seam 54 which would have formed the extreme outer edges of a metal blank from which the terminal is stamped and formed.
  • a bridge 56 is formed at the front and at the rear of pressure portion 52, with each bridge defining a pair of downwardly depending flanges 58 having forwardly and rearwardly directed teeth 60.
  • bridges 62 are formed at the front and at the rear of base portion 50.
  • the bridges define upwardly projecting flanges 64 which have forwardly and rearwardly projecting guide bosses 66 which have downwardly facing shoulders 67.
  • Upwardly projecting teeth 58 are formed on each opposite side of base portion 50
  • teeth 70 are formed on each opposite side of pressure portion 52.
  • teeth 68 and 70 are located to define two pairs of opposing teeth, with one opposing pair of teeth 68,70 being located on each opposite side of base portion 50 and pressure portion 52.
  • a pair of deformable arms 72 join base portion 50 and pressure portion 52 on each opposite side thereof.
  • the deformable arms have weakened or thin areas 74 defining an intermediate hinge area of the arms, as will be described hereinafter.
  • the terminal has a connecting portion which is not shown in the drawings but is broken away, as at 76. This connecting portion can take a wide variety of configurations for connecting the terminal and, thus, shield 12 of cable 14 to an appropriate ground.
  • Figures 6 and 7 correspond to Figures 1 and 2, respectively, and show the operation of terminal assembly 10 and, particularly, terminal 18 in terminating shield 12 of cable 14. More particularly, as stated above, Figures 1 and 6 show terminal 18 positioned within receptacle 38 of housing 16 in an open condition so that cable 14 can be inserted through opening 26 in front wall 28 of the housing and into the open terminal.
  • guide bosses 66 on flanges 64 enter guide groove 46 of the housing.
  • the terminal 18 moves into the housing until shoulders 67 on the guide bosses engage shoulders 48 of the guide grooves 46 leaving some clearance between the bottom wall 32 of the housing 38 and base portion 50 of the terminal. The clearance is required for energy storage.
  • Figures 2 and 7 show that a force has been applied in the direction of arrow "B" to the top or pressure portion 52 of terminal 18. This drives teeth 70 of the pressure portion downwardly in the direction of arrow "B” toward teeth 68 of base portion 50.
  • deformable arms 72 deform about hinge areas 74 and move outwardly into holes 42 in housing 16.
  • teeth 60 bite into the walls of guide grooves 46 and thereby provide a complementary interengaging latch means between the housing and movable pressure portion 52 of the terminal to hold the pressure portion in its actuated position and, thereby, to hold teeth 68 and 70 in their shield-clamping position.
