Definitions

  • This invention is concerned with electrical connectors for multi-core cables and, particularly, with cylindrical connector members for coupling to mating members having a plurality of radial bayonet studs.
  • Such connector members commonly include a substantially tubular shaped metal shell surrounding an insulating insert which firmly supports a number of contacts, each contact being joined within the shell to a core of a multi-core cable.
  • a cylindrical mating member supporting a corresponding number of mating contacts enters the shell when connection is made, a plurality of external radial bayonet studs on the mating member entering corresponding entry slots in the connector member to engage retention means which may include a snatch safety feature such that when a cable is pulled with excessive force, the connector and mating members will separate.
  • a substantially cylindrical connector member for coupling to a mating member, said mating member supporting a first plurality of contacts and having a plurality of external bayonet studs
  • said connector member including an integral body part of an insulating material, said body part including a first region of substantially solid cross section adjacent to a second region which has a substantially cylindrical open ended cavity extending to the front of said connector member, said first region having a plurality of axially directed through-holes which support a second plurality of contacts, said contacts extending into said cavity, said body part including an annular recess surrounding said cavity, said annular recess enclosing reteation means which engage said bayonet studs and said first plurality of contacts mating with said second plurality of contacts when said connector member is coupled to said mating member.
  • a standard bayonet receptacle member 1 has a plurality of female contacts 2, each of which is mounted into an axially directed bore in an insulating part 3 of circular cross section.
  • An outer tubular part 4 which may be metallic, surrounds the insulating part 3 with an annular gap 5 between the members 3 and 4.
  • the female contact connectors are joined to an associated multi-core cable or a number of electrical leads (not shown) in known manner.
  • a plurality, commonly three, of radial studs 6 are provided on the exterior surface of the tubular member 4 to engage with retaining means 7 in the associated connector member 8.
  • One or more axially directed keyways 9 are provided on the interior of the tubular member 4 to engage with one or more alignment splines 10 in the associated connector member to ensure correct rotational alignment of members 1 and 8.
  • a connector member 8 according to one example of the invention is shown in Figures 1, 2 and 4.
  • An integral body part 11 is formed from an insulating material, preferably a moulded plastics material, for example. glass filled nylon.
  • the body part 11 has cylindrical recesses at each ends and an inner region 15 of substantially solid cross section. Axially directed through holes 12 in the region 15 support a number of male contacts 13 with a sliding fit, the contacts 13 extending at each end into the respective cylindrical recesses.
  • An annular cavity 16 in the front region of the body part 11 surrounds the front cylindrical recess 14 such that, when the connector member is joined to a receptor member, the part 3 enters the recess 14 and the part 4 enters the cavity 16, permitting the male contacts 13 to engage with the female contacts 2, one or more alignment splines 10 being provided in the connector body part 11 to engage with mating keyways 9 in the receptor member or vice-versa. Entry slots 17 for the bayonet studs & are provided at the front of the body part 11.
  • the annular cavity 16 has a recessed portion 18 into which a circular resilient retaining member 7 is inserted.
  • the retaining member is a strip of resilient material which may be metallic, for example, spring steel or berillium copper, and may be initially fcrmed as a slotted flat strip, as shown in Figure 5, and then formed to a tubular shape as shown in Figure 6.
  • a number of substantially Y-shaped slots 19 are provided in the strip which align with the entry slots 17.
  • the slots 19 have a tapered entry such that the dimension "A" of Figure 5 is greater than the diameter of a bayonet stud and the dimension "B" is less than the diameter of a bayonet stud.
  • Additional slots 20 are provided to either side of each slot 19 such that their presence, associated with the resilience of the retaining strip material, permits the bayonet studs to pass through the narrow portions B, enabling the connector and receptacle members to be retained with a rapid axial pushing action.
  • the retaining strip may be designed such that the connector and receptacle members can be parted with an axial pulling force of greater than a pre-determined strength, thereby providing a snatch safety feature. This pre-determined minimum parting force may readily be chosen to be sufficiently large to prevent accidental disconnection during normal usage, while being sufficiently small to permit disconnection rather than damage and possible exposure of live conductors should a cable be accidentally snatched or pulled.
  • the retaining member 7 has one or more keyways 21 which engage with mating protrusions 22 in the body part 11 to ensure that the slots 19 align with the entry slots 17 and the retaining member is prevented from rotation.
  • the dimensions of the body member 11 and of the retaining member 7 are such that, when the connector member and the receptor member are connected, the holes 12 axially align with the female contacts 2, thereby ensuring alignment of the male contacts 13 with the female contacts 2. It will be . apparent that the resilient strip 7 and the front member 11 may be mass produced to fine dimensional tolerances at low cost, and the assembly of these two components provide entry guidance and retention means for the bayonet studs while ensuring the alignment of male and female contact members.
  • Each of the male contacts 13 has a thickened portion 23 which rests in a counterbore in each of the through-holes 12.
  • the male contact portions to the front of the thickened portions are of solid section and are a sliding fit in the bores 12.
  • the contact portions behind the thickened portions are hollow and permit the entry and crimping of bared ends of the cores 24 of a multi-core cable 25.
  • the hollow portions 26 of the male contacts extend into the rear cylindrical recess 27 in the body part 11 and are a sliding fit in through-holes 28 in a first insert 29, the holes 28 aligning with the holes 12 in the front member 11.
  • the first insert 29 is of an insulating material, preferably a moulded plastics material for example a glass filled nylon, and is substantially cup shaped.
  • a second substantially cup shaped insert 30 surrounds the cable 25 and meets the insert 29 to form a cavity 31 which contains the cable cores 24.
  • the cable is threaded through a bush 32 of for example a rubber or resilient plastics material which is surrounded by a clamp nut 33.
  • the second insert and the clamp nut are again preferably of a moulded plastics material, for example a glass filled nylon.
  • the rear portion of the body part 11 is externally threaded.
  • a resilient washer 34 is positioaed inside the clamp nut 33 and behind a widened front portion of the resilient bush such that the clamp nut may be screwed on to the threads of member 11 and when fully tightened, the two inserts and the front portion of the resilient bush are firmly supported within the rear cylindrical recess 27 and the male contacts are firmly supported with first insert 29 pressing against their widened portions.
  • a retaining clip 35 for example a crimped metal clip, is secured around the cable such that the cable is prevented from withdrawing from the bush 32, and the individual cores 24 leading to male contacts are contained within the cavity 31.
  • a strain cord 36 to be secured to the retaining clip at 0 ⁇ e end and for a knot or nipple 37 at its other end to be retained in a recess 38 in the first insert, the strain cord passing through a slot, shown at 43 in Figure 7, in to the cavity 31.
  • a strain cord may be used to provide additional protection against strain when using cables with fine cores.
  • Figures 7 and 8 show front end views of the first and second inserts respectively, Figure 8 also showing the cable 25 with retaining clip 35 and strain cord 36.
  • the inserts 29 and 30 each have one or more exterior alignment grooves, 39A, 39B, 40A and 40B, and the mating faces of the inserts have one or more location studs or protrusions 41A, 42A to locate with mating recesses 41B, 42B.
  • the mating faces of the bush 32 and of the second insert 30 are conically tapered to ensure their axial alignment.
  • One or more studs or protrusions are provided on the inner surface of the rear cylindrical portion of the body part 11 to provide loosely fitting guidance for the grooves 39A, 39B, 40A, 40B when the inserts are inserted into the recess 27.
  • the component parts of the connector member may be manufactured at low cost by well known production methods. It will also be apparent that the connector member is constructed such that the internal conductors are well protected against strain and substantially shielded from moisture or other hazardous environments. Furthermore, the construction is such that the component parts may be rapidly assembled together in a self-aligning manner, involving the following sequence of operations:
