12 Claims. (Cl. 339-89) (Granted under Title 35, US. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
This invention relates to couplings between coaxial cable ends.
Prior couplings between ends of coaxial cables have been not entirely satisfactory because of high voltage breakdowns, particularly in submarine RF transmissionline systems, in the air within the coupling means, such as may be due to avalanches of electrons which occur when a random electron is suiciently accelerated by a high gradient to ionize molecules of the air by collision. The breakdown voltage in a gas decreases as the frequency is raised. Hence all air should be eliminated from the connectors as far as possible, in the parts wherev a high voltage gradient exists.
Objects of this invention are to produce an improved coupling between coaxial cable ends, which eifectively reduces danger of high voltage breakdowns, which reduces to a minimum the presence of air where there is a high voltage gradient, which insures a tight high pressure Contact between dat faces of the abutting ends of the dielectric bodiesfat the coupling which is free of entrapped air alongthe inner conductor, with which air is substantially eliminated 'by contact between the dielectric bodies of the cable ends being coupled before metal-to-metal contact prevents further movement, with practical tolerances in the critical regions, which enables easy, rapid and convenient coupling and uncoupling of the cable ends, which prevents movement of moisture through the coupling between the exterior and interior thereof, and which is relatively simple, practical, durable, effective, compact, strong and inexpensive.
Other objects and advantages Will appear from the following description of one embodiment of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims.
In the accompanying drawings:
FIG. l is a longitudinal sectional elevation through two coaxial cable ends coupled in accordance with this invention;
FIG. 2 is a similar View separately of one of the dielectric bodies employed in the coupling;
FIG. 3 is a sectional elevation of a coupling part of the same; and
FiG. 4 is a sectional elevation on a larger scale or" one end of the coupling part of FIG. 3.
In the illustrated embodiment of the invention, the coupling is between cable ends 1 and 2. Each cable end has an inner conductor 3 and a surrounding concentric conductor d, such conductors being separated by an interposed body 5 of suitable dielectric material. The outer conductor is encircled by an insulating layer or sheath 6. In preparing each cable end for the coupling, its outer conductor 4 and the dielectric body 5 therein are out off short of the inner conductor 3 at its free end vso as to leave an endwise extension 7 of the inner conductor.v Fitted over each free end of the cable which is to be coupled, is a body 8 of high quality dielectric such as a tetrafluoroethylene polymer, one of which is marketed under the trademark Teflon Each such body S has a recess 9 in its end face which abuts a cable end, and the peripheral wall 10` of that body which forms the peripheral wall of this recess 9 is outwardly divergent, as illustrated. This body 8 is shown separately in FIG. 2. Each body has a passage 11 from end to end, one end of which lits loosely over the projecting end '7 of an inner conductor 3, and the divergent wall 19 of the recess 9, telescopes over the adjacent end of the dielectric body 5. The outer sheath 6 of insulating material on each cable end is cut back somewhat from the free end of that cable end so as to expose the outerconductor 4 for a short distance from the cable end, and then the outer conductor is turned back outwardly upon and spaced from itself, as at 12, so as to provide a rearwardly facing annular channel 13 which is located some distance from the free end of the dielectric body 5 of the cable. Disposed on the free end portion of each dielectric body 5 is an annular wedge ring 14 which rits fairly snugly with the end of the body S,but is able to slide lengthwise alongV the cable on such dielectric body. The inner periphery of the Wedge ring i 14 is cylindrical and its outer corner edges are beveled capable of being deformed to to provide tapered side edges. The beveled or tapered edge of the wedge ring nearest the free end of the related dielcctric body 5 is complementary to and ts the outwardly divergent peripheral wall 1t)` of the recess 9.
Another ring 15 surrounds and slides on the exposed periphery of the free end of each body 5 of dielectric, and it has a tapered wall 16 which is complementary to the adjacent tapered edge of the wedge ring 14 against which it abuts. The turned back end 12 of the outer conductor `abuis against the untapered or unbeveled side edge of the ring 1'5, as shown in FIG. 1. Also surrounding the outer conductor 4 of each cable end and slidable thereon, adjacent the turned back edge 12, is a clamp ring 17, whose opposite side edges are offset radially from one another with the one edge thereof which is of smaller diameter than the other edge received in the channel 13 ofthe turned back edge 12 of the outer conductor. The edge of the ring 1'7 which is of largerydiameter is slidingly received on the outer periphery of the sheath 6 so as to telescope slightly over the end of sheath 6. The free end of each dielectric body S is reduced in diameter through a tapered transition portion 18, and a metal sleeve 19 telescopes over and surrounds the body il of dielectric material of one cable end, such as the end l and also telescopes over the adjacent rings li, 15 and 17, and extends along and is radially spaced slightly from the sheath 6.
A tubular gland 2@ is threaded into the open end of the metal sleeve 19 at its end which lits over the sheath 6, and its inner end abuts edgewise against a side edge of the ring 17 so as to force it and the turned baclr edge 12 of the outer conductor against the ring l5. This pressure causes the ring 15 to ride upwardly on the tapered edge of the wedge ring 14 into contact with the inner periphery of sleeve 19 and also force the ring 14 firmly against the peripheral wall lil of the recess 9 so as to make a firm contact therewith. The sleeve 19, at the end of its passage which is away from the cable end, is reduced in diam-l eter through a tapered transition passage wall 21 which is complementary to the tapered passage wall 18 of the body 8 of dielectric material. This wall 21 of the passage oi the sleeve 19 serves as an internal abutment which engages with the tapered wall 18 of the dielectric body 8 and cams it iirmly against the end of the dielectric body 5 of the cable. The free end of sleeve 19 extends a short distance beyond vthe end of the dielectric body 8. The sleeve 19, as well as the rings l5- and. 17 are of metal orother electrically conducting material. Ring 14 is of an insulating material having a low loss factor at radio frequency andi press firmly against the cable i dielectric, thereby compensating for the large tolerance common in coaxial cables and also thereby lilling up voids which otherwise might permit corona or promote breakdown.
The other cable end 2. is similarly itted into a metal sleeve 22 which is generally similar to the sleeve 19 except that at its extreme free end it telescopes over the free end of the sleeve 19 where `they meet at the coupling. The sleeve 2.2 is also made of metal. Encircling the free end of the sleeve Z2. and rotatably thereon is another sleeve 23 which is also of metal. It is conlined against endwise sliding motion on the free end of sleeve 22 by a split spring ring 24 which is received in an annular channel or groove 25 provided in the external periphery of the sleeve 22 a short distance inwardly from its extreme free end edge. This split ring is also received in an internal annular groove or channel 26 in the sleeve 23, so that this split ring confines the sleeve 23 against endwise movement on the sleeve 22 but leaves it free for rotation thereon. This sleeve 23 acts as an extension of the outer end of sleeve 22, and at its free end has internal screw threads 27 which mesh with external screw threads 28 on the periphery of the sleeve 19 beyond the telescoping portions between the two sections 19 and 22. By rotating the sleeve 2.3 to engage its threads 27 with the threads 28 of the sleeve 19, it is possible to couple the adjacent ends of sleeves 19 and 22 through sleeve 23 and draw them toward one another while in telescopic relationship on their adjacent ends. An elastic sealing ring or O-ring 29 is conined in an annular channel 30 in the exterior periphery of the extending end of the sleeve 19 where it is in sliding engagement with the inner periphery of the tree end of sleeve 22, and where the adjacent ends of the sleeves 19 and 22 are in sliding telescoping relationship. This sealing ring or O-ring is under radial compression between the inner periphery of the sleeve 22 and the body of the channel or groove 30, and thus provides a fluid resistant seal between the telescoping ends of the sections 19 and 22. The lengths of the dielectric bodies 8 on the cable ends are such that the reduced ends of the bodies 8 on the two cable ends will engage endwise and abut with one another firmly before the telescoping ends of the sleeves 19 and 22 are limited by contact with one another at the end edges of the telescoping sleeves. Thus, there is a slight air gap or space between each free end of sleeves 19 and 22 and the abutment on the other sleeve, which enables the sleeves 19 and 22 to be drawn together far enough to ensure lirm abutting contact between the adjacent ends of the dielectric bodies S ofthe two cabled ends.
A metal ring 31 is secured liush in a channel or rabbet 32 in the inner periphery or passage of the sleeve 2v2 a short distance from its free end. The ring 31 has a tubular, thin flange 33 extending endwise thereof along and in contact with the free reduced diameter end of the body 8 within the sleeve 22, and the passage Wall of reduced cross section in the sleeve 19, which lies along the liange 33, is slightly outwardly divergent so that as the ends of the sleeves 19 and 22 telescope in coupling the cable ends 1 and 2, this divergent wall 34 will engage and telescope with the flange 33 in a sliding cam action thereon and force it against the reduced end of the body 8 in the sleeve 2,2, and thus ensure a lirm electrical contact and connection between the sleeve 19, flange 33, ring 31, and the sleeve 22. Flange 33 is slit longitudinally into several sections or fingers to provide the flexibility required for this sliding contact. As shown more clearly in FIG. 2 where the body 8 of dielectric material is illustrated, the free end face of the reduced diameter end of at least one body 8, preferably is beveled or deviates slightly from a plane through the free end of that body 8 perpendicular to its longitudinal axis by receding slightly from that plane as it progresses outwardly from the portion of the end face at the passage 1l through the body. Preferably both free ends of the bodies 8 are similarly beveled or made to recede from such plane in order that the bodies 8` canY be all identical. Such a deviation from such plane can be advantageously made about l degree. Thus, the end face of the reduced end of each body 8 is slightly frustoconical by about one degree deviation from a plane that abuts the free end and is perpendicular to the axis of passage 11.
Since the dielectric material of which the bodies 8 are made is a high-grade dielectric which is slightly elastic, it follows when two such ends of the bodies 8 abut, they will engage tirst at the margin oil the passage 11 and then, as the abutting pressure increases, the contact between those end faces will spread outwardly from the initial line of contact at the margin of the passage until the end faces of the bodies 8 contact irmly'with one another over their entire end faces. During this action any air which is disposed between the end faces of the bodies 8 will be progressively squeezed outwardly, so that none will remain trapped between the abutting end faces of the bodies 8 when the coupling of the cable ends has been completed.
The passages 11 in the two bodies 8 of the dielectric material are aligned with one another, and receive and hold therein metal conducting means which fits over and connects the extending ends 7 of. the inner conductors of the ytwo cable ends, and this connecting conducting means is formed of endwise telescopic sections that are engaged as the cable ends are brought toward one another before the coupling is completed. This enables preliminary adjustment of the sleeves 19 and 22 to different extents of telescoping relationship when bringing the ends of the bodies 8 of dielectric material into firm strong contact with one another, as explained above.
In the illustrated embodiment of the invention, this connecting means between the inner conductor terminals 7 of the cable ends includes a metal member 35 which has in one end a recess 36 providing a tubular sleeve 37 on its end, which telescopes over and snugly fits the adjacent end 7 of the inner conductor that is received in the passage 11 of the block 8 of dielectric material which fits over the cable end 1. This provides a firm electrical contact between the inner conductor and the member 35. The recess 36 is longer or deeper than the received end 7 of the inner conductor, which permits the member 35 to be adjustable along the received end 7 of the inner conductor.
Another member 38 of metal is received in the passage 11 of the other body 8 which is within the sleeve 22. This member 3S has a recess 39, in one end, which provides a tubular sleeve 40 that snugly fits over and telescopes with the end 7 of the inner conductor on the cabled end Z. Preferably in the passage 11 of each of the blocks 8, there is provided a slight internal shoulder 41 which faces toward the abutting ends between the blocks which limits the movement of the members 35 and 38 along the passage 11 as they telescope over the inner conductor ends 7. The member 35 terminates within the passage 11 of the block 8 which is within the sleeve 19, a short distance from the reduced end of that block 8, and in that end of the member 35 there is another deep recess 42 which provides a tubular sleeve 43 as an end terminal of member 35. The member 38 has a rounded end portion 44 of reduced cross section which is slit endwise from its free end for a substantial distance, as at 45, so as to provide spring fingers which telescope within and resiliently fit the walls of the recess 42 in member 35 so as to provide a firm electrical contact between the members 35 and 38. The free end of the ange 43 which telescopes with the member 38 terminates short of the junction between the reduced end and the larger diameter of the member 3S, so as to enable substantial endwise sliding movement of the reduced end 44 of the member 38 in the recess 42 of member 35.
The free end edge of the sleeve 43 is rounded as at 46, in order to reduce the danger of electrical discharge from the free edge of the sleeve 43. For the same reason, the free end of the member 38 is tapered. The maximum dof/enea diameters of members and 3S are equal. The inner diameters of Ene sleeve 19 and of the -ange 33 are also equal. The ratio of outer to inner diameters in the vicinity of the abutting ends of the bodies 8 is made approximately equal to 2.7, thereby minimizing the voltage gradient. One of the sleeves such as sleeve 19 may carry a peripheral mounting tiange 417, by which the coupled ends may be supported in any suitable manner, not shown.
It is believed that the manner of coupling and unconplingV the cable ends in accordance with this invention will be apparent from the detailed description hereinabove. The two cable ends 1 and 2 may be uncoupled by merely rotating the sleeves 23 to disengage its threads 42'7 from the threads 28 of the sleeve 19, `during which the two cable ends are pulled apart and the member 33 is withdrawn from the recess 42. The cable ends 1 and 2 may be assembled by bringing them into end ,to endvrelationship, inserting the rounded end 44 of the member 33 into the recess 42, telescoping the sleeves 19 and 22, and reengaging the threads 27 of the Vsleeve 23 with the teeth `23 on the sleeve 19. By rotating the sleeve 23 it vwill draw the telescoping endsof sleeves 19 and 22 together until the ends of the bodies 8 of dielectric material abut and progressively squeeze outwardly any air that may lie between the abutting end faces of the dielectric blocks 3. v
l lt will be observed that with this arrangement, the dan- 'ger of breakdowns due to high voltage, are substantially eliminated, the entrapped air is reduced to a minimum wherever there is ahighvoltage gradient, and a rm electrical contact is made at alltimes between the inner conductor ends I of the two cable ends 1 and 2 whenever the cable ends arecoupled, as explained above.
A firm electrical connection is made between the outer conductors 4 and tliersleevesl 19 and 22, and between sleeves 1,9 and 22 where they are coupled. I l It will be understood that'various `changes in the details, materials and arrangements of parts, which have been herein described and illustrated inorder to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
