Definitions

  • This-invention relates to electric cable coupling devices as used for connecting together electrically the cable conductors of one length of cable with those of another or of some other electrical apparatus.
  • the coupling device embodies contact members which are electrically connected to the ends of the conductors of the cable to be coupled, and are supported in a body of moulded insulating material. It will be understood that before the moulding operation can be carried out a certain amount of preliminary Work upon the end of the cable will have to be done. This will include the removal of the outer covering or coverings of the cable to expose the insulated cable conductors for an appropriate' distance. It will also include the removal of the insulation from the exposed cable conductors for an appropriate distance so that the contact members may be electrically'connected subsequently to the cable conconstructed and manufactured according to the present invention has this and other advantages.
  • an electric cable coupling device comprises an inner body of moulded insulating material, in which those portions of the cable-conductors extending" beyond-the cut back end, are embedded, and an outer body or" moulded insulating material which surrounds and extends beyond'the' inner body and supports contact members electrically connected to the cable conductors.
  • the method of manufacturing an electric cable coupling device comprises exposing the component 'parts'of the cable for appropriate distances, moulding a body of insulating material around those portions of the cable conductors projecting beyond the main body of the cable, to form an inner body of insulating material, electrically connecting contact members for the coupling device to the projecting ends of the cable conductors and then moulding a second body of insulating materialaround the inner body to support the contact members.

  • the coupling device illustrated in the accompanying drawings is shown applied to one form of construction of electric cable of the kind used with television cameras.
  • the arrangement of the cable conductors will be seen from Figure 1 of the drawings.
  • At the inner part of the cable there are six individually insulated conductors 1 arranged in pairs, the two conductors of each'pair being embedded in a body of insulating material 2.
  • a metal braided screen 3 Over each of such bodies is applied a metal braided screen 3 and over each of the latter there is applied helically an impregnated textile tape 4.
  • Each pair of insulated conductors together with its outer layers forms a unitary structure and is referred to as a core.
  • the three cores are laid up helically together.
  • each group consisting of three individually insulated conductors, the reference numerals 6 indicating the insulation.
  • the three conductors of each group are not laid up together helically but are laid in the helical interstices formed between the three cores.
  • a circular layer of individually insulated conductors 7 is applied over the three cores and three groups of insulated conductors 5 .
  • the insulated conductors 7 are applied helically and an impregnated textile tape 9 is wrapped helically over those conductors. Over the tape 9 is applied a metal braided screen 10 and over the latter is applied a sheath 11 of polyvinyl chloride.
  • the conductor insulation in each case is polyethylene and the cable has a total of thirty-six conductors. Although certain spaces between some of the insulated conductors are shown in the figure, this has been done for the sake of clarity. As will be understood these spaces will not exist in the cable as manufactured.
  • the exposed end of the screen if is opened out and formed into a number of separate ends. These'ends ars'saown at 14 and are enmped'between the two rings 12 and 13.
  • the ring 13 hasa series of ci-rcu'mferentially arranged untapped holes which register with similarly arranged tapped holes in the ring 12.
  • the two rings are held together by screws 17 passing through the untapped holes and screwing into the tapped holes.
  • the screws have lock nuts 18.
  • each cable conductor terminates at a short distance beyond the cut back end of the sheath 11.
  • the screens 3 and tapes 4 are cutback, the ends'of the latter being held in place by wrappings 19 of insulating'material and the ends of the screens 3, by wi'appings 28 of insulating material.
  • Over the projecting insulated end of each conductor is placed 7 and insulating sleeve 21 of varnished cambric and the three screens 3 areelectrically connected to each, other and to the ring 13 by winding a piece of bare wire 28 around the three screens and soldering the wire to them and retaining one end of the wire between a washer 29 on one of the screws 17 and the metal ring 13. All these preliminary operations are carried out and completed before the contact members are attached to the ends of the conductors.
  • the metal sleeve is integral with a flange 25 which is integral with a lateral extension 26 of the ring 12, the latter and the flange 25 forming between them an annularrecess 27.
  • the mould 23 when placed in position, fits around :the cable end against the flange'25 and encloses the metal rings '12 and 13 and those portions of the conductors provided with the insulating sleeves 21.
  • the mould 23 consists of two main parts adaptedto be fitted and held together around the end of the cable.
  • .An aperture 30 in a side wall 34 of the mould provides for the injection under pressure of the insulating material into the mould through a'nozzle 31.
  • the side wall of the mould has a second aperture 32 extending through it and through a small boss 33 extending inwardly from the in per surface of rthe side wall;
  • the wire 28 electrically con- ..n-ecting the screens 3 and the ring 13 is taken through the .aperture' 32 to the outside of themould 23.
  • the latter is closed by a removable end plate 35 provided with apertures through which the bared ends of the conductors project in the manner shown'in Figure 3.
  • the moulded body 35 is shown with a metal screen 38 partly enclosed by the body and extending beyond it in the longitudinal direction or" the cable.
  • This screen is arranged to surround the three pairs of con-' ductors 1 ( Figure l) at their ends and the contact members connected to those ends.- The'end of the screen 38 nearer to the cut back end ofthe cable is housed in a recess ofja n appropriate shape formed in the'moulded body 36 during themouldiug operation already described The shape-of the recess receiving the screen will beseen from Figure 5 where the recess 'is shown at 39. The latter is composed of a portion 48 of circular cross-section, radial ductors;
  • the screen 38 is of cor- V responding shape and, as will be seen from Figure 9, consists of a portion 43 of cylindrical cross-section, through which extends an axially disposed rod 44 and three fins 45 extending between the central rod and the portion 43.
  • the screen 38 is electrically connected to the ring 13 by a bare wire 46 ( Figure 6) which is connected to the 'erid of the screen 3 nearer the ring 13.
  • the wire 46 is housed in a curved passage 47 in the moulded body 36, the passage extending from the central portion 42 of the recess to the outsideof the moulded body where it terminates at the recess 37.
  • the recess 39 and the passage 47 are 7 formed during the moulding'operationalready described.
  • the inner side of the end plate 35 is provided with a series of projections 48 which together form a pattern of the shape required to form the recess 39. A part of the circular portion 46 and of the central portion 42 of the recess are shown in Figure4.
  • the curved passage 47 is produced by forming the moulded, body 36 around a flexible core 53 having a smooth curve in it and of larger diameter than the wire 46.
  • the core' is anchored at one end in any convenient manner and extends through the centre one of the projections 48 and through the end plate 35 to the outside thereof. Afiter the moulding operation the core is withdrawn from the moulding.
  • a curved wire or other smooth flexible member of suitable material may be used for the core.
  • the wire 46 connected to the screen 38 is threaded through the "passage 47 so that it extends beyond the moulded ,body 36, the screen 38 at the same time being guided into its recess 39.
  • the screen 38 can be electrically'connected to the'ring 13 by suitably joining the outer ends of the wires 28 and 46.
  • the end of the cable, the moulded body 36 and the pins attached thereto and the screen 38 which has now been placed in its recess, are now enclosed in a second mould 50, as shown in Figure 7.
  • the mould is of twopart construction. Screws (not shown) passing through the wall of the mould and entering the tapped holes 62 To prevent the injected insulating material completely enclosing the pins 49, a' plate 81 is formed with recesses 51 which receive the end parts of the pins.
  • a second body of insulating material is moulded round the moulded body 36 by injecting 'under pressure insulating ma terial' atone end of the mould-59 through a nozzle '52 at the side of the mould and communicating with a passage 54 and passages 55 in a member 80, the passages 55 communicating-with passages 82 extending through'the plate 81 into the interiorof the mould 50.
  • This opera- ,tion results inthe formation of an outer moulded body 56 as shown in Figure 8; --The outer moulded body fills up the recess 37 in the side of the inner mouldedbody' 36 andit supports the pins 49 firmly in position; Itlalso 'supports the.
  • annular recess SS and flange 59 ' are formed during the moulding of the body 56'by' an inwardly extending projecting portion 61 of the inner surface of the mould and an annular recess 66 in that surface, as shown in Figure 7.
  • the contact members consist of the pins 49 and assuming that two lengths of cable are to be coupled the second length of cable will be provide at its end with a coupling device embodying contact members having the form of sockets, coupling being effected by a relative axial movement of approach of the two coupling devices to bring the pins 49 into engagement with the sockets.
  • FIG 10 there is shown a coupling ring 64 which encloses the exposed ends of the pins 49 and the inner surface of which has at the outer end of the ring a screw-threaded portion 65.
  • the coupling ring 64 is carried by a metal sleeve 66 which surrounds and makes a close fit with the outer body 56 of moulded insulating material.
  • the sleeve is made of sufficient length to extend over the two clamping rings 13 and 12 and for a short-distance beyond the latter.
  • the sleeve is retained in position by being attached by a number of screws 67 which pass through holes in the sleeve and enter the holes 62, which are tapped, in the metal clamping ring 12.
  • Thesleeve 66 is of substantial thickness and affords mechanical protection for the inner and outer moulded bodies of insulation against damage. Should, however, the sleeve 66 or the coupling ring 64 become damaged, a new coupling ring and sleeve can be fitted readily by removing the screws 67 and drawing forward the old ring and sleeve and replacing those parts by a new ring and sleeve and attaching the latter to the coupling ring 12 bythe screws 67.
  • the coupling ring 64 and sleeve 66 can be placed in position after the cornpletion of the moulding operations is of advantage as it facilitates the appropriate setting up of the cable condoctors in the moulds preparatory to the carrying out of the moulding operations and the attachment and replacement of the sleeve 66 and coupling ring 64 can be carried out without disturbing the moulded bodies 36 and 56 .of insulating material or the cable conductors or pins attached thereto.
  • the coupling ring 64 and sleeve 66 are not placed in position until after the completion of the second moulding operation, the attachment of the pins 49 to the ends of the cable conductors after the completion of the first moulding operation is facilitated since the exposed ends of the conductors are freely accessible.
  • the pins may be conveniently attached to their cable conductors by a soldering operation.
  • a stout flexible sleeving 69 made of rubber, for example, which interlocks with the flange 59 forming part of the outer moulded body 56.
  • the sleeve is held in tight contact with the sleeve 66 by a binding 70.
  • the coupling ring 64 has three circumferentially spaced recesses formed in its inner surface. These are shown in Figure 11 being indicated by the reference numerals retained in position in the manner previously described.
  • the figure also shows a sleeve 72 having in its-outer surface an annular recess receiving a ring 73.
  • the sleeve 72 has at its outer end three circumferentially spaced projections 74, their spacing and'dimensions corresponding .to those of the recesses 71?
  • Figure 12 shows one only of the projections '74.
  • the recesses and projections areso arranged that engagement of the pins 49 and their sockets can be effected only when the pins are in axial alignment with their correct sockets, so that the required electric connections between the cable conductors of the two lengths of cable are obtained.
  • the coupling ring 75 is rotatable on'the sleeve 72 but is prevented from longitudinal movement along'the sleeve by the ring -73 and by the projections 74 which form abutments for the spigot portion 76 of the clamping ring 75.
  • the screens forming a part of the cable construction and the additional screen are all electrically connected to the clamping ring 12 and through the screws 67, sleeve 66 and coupling rings 64 and 75 and sleeve 72 to clamping rings similar to the rings 12 and 13 and from thence to the corresponding screens of the' second length of cable, when the two lengths of cable are coupled together. Electrical continuity and earthing of all the screens can thus be readily obtained although the additional screen 38 is embedded in the two moulded bodies 36 and 56 of insulating material.
  • the rings12 and 13 have been stated to be both made of metal, it may be an advantage in some cases to make one of them of insulating material in order to avoid excessive conduction of heat from the mould to the cable conductors during the mould ing operation.
