Definitions

  • This invention relates to multiaxial cables, connectors, and coaxial contact assemblys therefor. More particularly, the invention relates to termination of multiaxial cables, and, especially, to termination of miniature cables through contact assemblys usable in multipin electrical connectors and multicable electrical connectors.
  • coaxial cables are made up of:
  • Triaxial cable adds another dielectric material layer over the first outer conductor and adds a second outer conductor over the second dielectric layer.
  • the triaxial cable is protected like a coaxial cable.
  • All multiaxial cables must be terminated. Most commonly terminations involve the connection of two cable ends to complete a circuit or, in effect, lengthen the cable to reach a more distant location. These terminations involve electrical connectors: which may be for connecting two cables only, or as a contact assembly used in conjunction with wire or other contact assemblies in a multipin or multicable electrical connector.
  • Coaxial cable because of its complex structure is easily affected by atmospheric conditions and/or electrical interaction of the different materials in the sandwich or conductors and dielectric.
  • the protective jacket itself a dielectric, also has an effect on the electrical interaction. All these materials have coefficients of expansion and these can be widely different in a given cable. As a result the members of the cable have different length potentials at cable temperatures other than standard temperature.
  • the inner conductor does change length with temperature change, tending with increasing length to reinforce the disturbance caused by the inner dielectric length change.
  • the inner conductors terminated in an inner pin-socket contact shorten they try to pull the inner pin-socket contact apart.
  • the invention is directed to a contact assembly for terminating two multiaxial cables, under conditions where the inner pin-socket contact of said contact assembly is substantially captivated against axial movement.
  • the contact assembly comprises a pin housing and a socket housing for overlapped electrically conductive joinder; pin member and socket member located within respective pin and socket housings, for electrical mating; said socket housing and said pin member having abutting dielectric surface relationship when at the_mated condition for stopping forward axial movement at the inner pin-socket contact; said pin member and said socket member each having a barrel for receiving a cable inner conductor to be terminated within said contact assembly, which barrel can be crimped about said inner conductor; each pin housing and socket housing having a barrel portion over which corresponding outer conductors of terminating cables can be positioned; dielectric material inside of each of said pin housing and said socket housing to insulate the respective housing from its said member, said dielectric material essentially filling each said housing and extending beneath the respective outer conductors of said cables and forward to provide abut
  • the embodiment as shown is suitable for use in conjunction with a multipin connector, for example, the multipin connector of U.S. Patent No. 4,056,298.
  • a multipin connector for example, the multipin connector of U.S. Patent No. 4,056,298.
  • the embodiment needs protection against physical abuse, such as, a protective encasement, which encasements are well known to the coaxial connector art.
  • the drawing shows the contact assembly in a partially mated condition. This has been done to provide more space at the pin-socket contact zone, to show the various members in the zone. It is self-evident, the contact assembly is brought into abutting relation of the pin member and the socket housing member, when the pin and socket are fully mated.
  • the coaxial contact assembly for captivating inner pin-socket electrical contacts of the invention comprises an electrical socket assembly 10 (Figs. 1-la) for mating with an electrical pin assembly 70 (Figs. la-lb).
  • Socket assembly 10 is also referred to as the male assembly and pin assembly 70 is also- referred to as the female assembly.
  • Coaxial cable 14 is made up of inner conductor 18, inner dielectric material 20, and double braided outer conductor 22 and 24.
  • the protective jacket not shown, stops outside the-figure. It is to be understood the coaxial cable ends are shown to illustrate the utility of the invention, but are not part of the invention.
  • Socket assembly 10 comprises (Figs. 1-la) electrical socket member 30 having a pin receiving socket 32 at one end, away from coaxial cable 14, and a barrel 34 at the other end, having a squared rear end 35, for receiving a portion 36 of the inner conductor of the cable 14, when present.
  • the entry 38 (Fig. la) of socket 32 is beveled to ease entrance of the pin 92.
  • Socket barrel 34 is sized so that the inner conductor portion 36 may be crimped within the barrel, holding the conductor 36 and improving electrical contact.
  • An electrically conductive socket housing 40 (Figs. 1-la) is coaxially aligned around socket member 30 and has a cylindrical nose portion 42, which has a relatively squared end 44. The nose portion 42 extends beyond the entry 38 to socket 32. Socket housing 40 has at its other end a cylindrical barrel (tail) portion 46. Barrel 46 can be inserted underneath an end portion 48 of outer conductor braid 22 to make electrical contact therewith.
  • Dielectric materials 50 (Figs. 1-la) and 110 (Figs. la-lb) are substantially rigid, insulating materials with high resistance to cold flow, such as, polyester, polyamide, and polyimide.
  • Dielectric material 50 is positioned in socket assembly 10 between socket member 30 and socket housing 40 to electrically insulate these from each other and, also, socket member 30 from outer conductor 48; dielectric 50 essentially fills aforesaid space. Dielectric 50 extends back beyond socket housing tail portion 46 a substantial distance underneath outer conductor 48, when this is present, so as to underlie a ferrule 60. Dielectric 50 may be in one piece, but normally will consist of more than one piece for greater ease of manufacture and installation. In general, the number of pieces in dielectric 50 is determined by the configuration of the cavity between socket member 30 and socket housing 40. The individual pieces may be formed from the same type of material, or from different materials in the defined class of materials.
  • dielectric 50 is fitted as two pieces 52 and 54 (Figs. 1-la).
  • Piece 52 extends out to socket housing end 44 to insulate electrically nose portion 42 from electrical pin 92, when pin 92 and socket 32 are mated.
  • Dielectric piece 54 extends roughly from the outer end 61 of ferrule 60, at the approximate level of the outer surface of tail portion 46, underneath ferrule 60, end portion 48 of braid 22, tail portion 46 and forward until it abuts rear end 35 of socket barrel 34 at flat end 56.
  • a shoulder 55 of piece 54 abuts against end 47 of barrel 46, which shoulder 55 restrains piece 54 from movement toward socket barrel 34.
  • Piece 54 is provided with another shoulder 57 against which the inner end of cable inner dielectric 62 can abut in forward axial movement thereof. Ends 56, 57 and the dielectric therebetween bar the inner dielectric 62 from further movement toward the inner pin-socket contact zone and thereby minimise electrical disturbances caused by cable inner dielectric movement.
  • Socket assembly 10 includes a conductive ferrule crimp means 60.
  • Ferrule 60 encircles: socket housing barrel (tail) portion 46, socket assembly dielectric material 54, end portion 48 of outer conductor 22, cable inner dielectric 62, and that portion of cable inner conductor roughly under ferrule 60.
  • Ferrule 60 is of metal capable of being crimped to fasten together (1) the ferrule, the encircled tail portion, and outer conductor; and (2) the ferrule, outer conductor, and dielectric 54 extending beyond the tail portion. The crimp (2) restrains the inner pin-socket contact against rearward pull of inner dielectric and inner conductor.
  • Cable 74 is made of inner conductor 76, inner dielectric material 78, and a double braid outer conductor 80 and 82.
  • the protective jacket is outside the figure.
  • Pin assembly 70 as set forth in Figs. la-lb comprises an electrical pin member 90 having a pin 92 at one end, away from cable 74, and a barrel 94 at the other end for receiving a portion 96 of the inner conductor of cable 74.
  • Pin barrel 94 is sized so that innter conductor portion 96 can be crimped therein, holding inner conductor 96 and improving electrical contact.
  • An electrically conductive pin housing 100 (Figs. la-lb) is coaxially aligned around pin member 90 and has a cylindrical tapered nose portion 102 having forward end 103, end 103 being divided into a plurality of spring fingers for improving electrical contact with socket nose portion 42.
  • Pin housing 100 has at its other end a cylindrical barrel (tail) portion 106, for insertion underneath an end portion 108 of outer conductor braid 80 and to make electrical contact therewith.
  • Dielectric material 110 (Figs. la-lb) is positioned in pin assembly 70 between pin member 90 and pin housing 100 to insulate electrically these from each other, and also pin housing 100 from inner conductor 112 (Fig. lb). Dielectric 110 essentially fills aforesaid space. Dielectric 110 extends back beyond pin housing barrel (tail) portion 106 a substantial distance underneath outer conductor 80, when this is present, so as to underlie a ferrule 130.
  • dielectric 110 is fitted as three pieces 114,116 and 118 (Figs. la-lb).
  • Piece 114 goes forward to squared end 120 to insulate pin 92 from nose end 44 when the pin and socket are mated.
  • Dielectric piece 118 extends roughly from the outer end 131 of ferrule 130, at the approximate level of the outer surface of tail portion 106, underneath ferrule 130, end portion of braid 82, tail portion 106, and forward until it abuts the rear end 117 of dielectric piece 116.
  • Piece 118 is provided with a shoulder 119 against which the inner end of cable dielectric 132 abuts in forward axial movement and is barred from further movement toward the inner pin-socket contact zone, thereby minimising electrical disturbance caused by cable dielectric axial movement.
  • Shoulder 120 abutted against end 107 of tail portion 106 helps restrain forward movement of dielectric material 110.
  • Dielectric 116 runs into dielectric 114, described earlier.
  • Pin assembly 70 includes a conductive ferrule crimp means 130.
  • Ferrule 130 encircles: pin housing barrel (tail) portion 106, pin assembly dielectric material 118, end portion 108 of outer conductor 80, cable inner dielectric 132, and that portion of cable inner conductor roughly under ferrule 130.
  • Ferrule 130 is of metal capable of being crimped to fasten together (1) the ferrule, outer conductor and the encircled tail portion; and (2) the ferrule, outer conductor, and dielectric 118 extending beyond the tail portion. The crimp (2) restrains the inner pin-socket contact against rearward pull of inner dielectric and inner conductor.
  • Pin assembly 70 is provided with (Fig. la) a stainless steel cylindrical protective sleeve, 140, positioned on the exterior of pin housing 100 to protect the spring fingers at the forward end 103 of pin housing nose portion 102.
  • a suitable coaxial cable for termination by the contact assembly of the invention is RG 142/U in size 12 contact in conjunction with a multipin electrical connector.
  • This cable has a solid copper inner conductor; a PTFE dielectric (polytetrafluoroethylene); a braided copper outer conductor; and a FEP protective jacket (fluorinated ethylene propylene).
  • the pin and socket members, the pin and socket housings, and the cylinder with spring fingers are made from heat treated beryllium copper alloy.
  • the ferrules are soft beryllium copper alloy.
  • the dielectric material is polyamide.
