Abstract
Description
- 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. British Patent Specification No. 1403093 and European Patent Application No. 0082320, for example, each disclose connector members in which resilient elements are inserted into recesses lying to either side of each entry slot, while UK Patent Application No. GB 2063587A discloses a connector member in which the bayonet studs engage a spring loaded rotary latch.
- It is essential when assembling such connector members to ensure that the contacts are firmly supported in insulating material within the shell and that they will axially align with the mating contacts when the bayonet studs engage the retention means. Presently used methods of assembly commonly involve the steps of firmly bonding the contacts in the insert, which has been firmly fixed to the shell, and securing by, for example, soldering or crimping the cable core ends to the contacts before the securing of accessories. Such operations may be time consuming in requiring that the contacts are supported in ciorrect angular relationship with the retention means while ensuring that no cores become broken or disconnected, particularly when fine cored cables such as audio wires are to be connected. Furthermore, the provision of slots and recesses in a metal shell to ensure that the retention means are precisely located is likely to require costly machining operations.
- It is an object of the present invention to provide an improved connector member for use with a mating member provided with radial bayonet studs.
- According to the invention there is provided 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.
- An embodiment of the invention will now be described, by way of example, and with reference to the accompanying drawings in which:
- Figure 1 is a perspective view of a connector member according to one example of the invention shown partially cut away and an associated standard bayonet receptor member;
- Figure 2 is a perspective view of the connector member assembled to the associated bayonet receptor member;
- Figure 3 is a front end view of the bayonet receptor member;
- Figure 4 is a diametric section of the connector member;
- Figure 5 is a plan view of a resilient strip prior to forming a circular retaining member;
- Figure 6 is a front end view of a circular retaining.member formed from said resilient strip;
- Figure 7 is a front end view of a first insert.
- Figure 8 is a front end view of a second insert through which a multi-core cable and a retaining clip are threaded.
- Referring to Figures 1, 2 and 3, a standard
bayonet receptacle member 1 has a plurality of female contacts 2, each of which is mounted into an axially directed bore in aninsulating part 3 of circular cross section. An outertubular part 4, which may be metallic, surrounds theinsulating part 3 with anannular gap 5 between themembers radial studs 6 are provided on the exterior surface of thetubular member 4 to engage withretaining means 7 in the associatedconnector member 8. One or more axially directedkeyways 9 are provided on the interior of thetubular member 4 to engage with one or more alignment splines 10 in the associated connector member to ensure correct rotational alignment ofmembers - A
connector member 8 according to one example of the invention is shown in Figures 1, 2 and 4. Anintegral body part 11 is formed from an insulating material, preferably a moulded plastics material, for example. glass filled nylon. Thebody part 11 has cylindrical recesses at each ends and aninner region 15 of substantially solid cross section. Axially directed throughholes 12 in theregion 15 support a number ofmale contacts 13 with a sliding fit, thecontacts 13 extending at each end into the respective cylindrical recesses. Anannular cavity 16 in the front region of thebody part 11 surrounds the frontcylindrical recess 14 such that, when the connector member is joined to a receptor member, thepart 3 enters therecess 14 and thepart 4 enters thecavity 16, permitting themale contacts 13 to engage with the female contacts 2, one or more alignment splines 10 being provided in theconnector body part 11 to engage withmating keyways 9 in the receptor member or vice-versa.Entry slots 17 for the bayonet studs & are provided at the front of thebody part 11. - The
annular cavity 16 has arecessed portion 18 into which a circular resilient retainingmember 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 theentry slots 17. Theslots 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 eachslot 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. Furthermore, 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 retainingmember 7 has one ormore keyways 21 which engage withmating protrusions 22 in thebody part 11 to ensure that theslots 19 align with theentry slots 17 and the retaining member is prevented from rotation. The dimensions of thebody member 11 and of theretaining member 7 are such that, when the connector member and the receptor member are connected, theholes 12 axially align with the female contacts 2, thereby ensuring alignment of themale contacts 13 with the female contacts 2. It will be . apparent that theresilient strip 7 and thefront 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 thickenedportion 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 thebores 12. The contact portions behind the thickened portions are hollow and permit the entry and crimping of bared ends of thecores 24 of amulti-core cable 25. Thehollow portions 26 of the male contacts extend into the rearcylindrical recess 27 in thebody part 11 and are a sliding fit in through-holes 28 in afirst insert 29, theholes 28 aligning with theholes 12 in thefront member 11. Thefirst 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 shapedinsert 30 surrounds thecable 25 and meets theinsert 29 to form acavity 31 which contains thecable cores 24. The cable is threaded through abush 32 of for example a rubber or resilient plastics material which is surrounded by aclamp 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 thebody part 11 is externally threaded. Aresilient washer 34 is positioaed inside theclamp nut 33 and behind a widened front portion of the resilient bush such that the clamp nut may be screwed on to the threads ofmember 11 and when fully tightened, the two inserts and the front portion of the resilient bush are firmly supported within the rearcylindrical recess 27 and the male contacts are firmly supported withfirst insert 29 pressing against their widened portions. Aretaining clip 35 for example a crimped metal clip, is secured around the cable such that the cable is prevented from withdrawing from thebush 32, and theindividual cores 24 leading to male contacts are contained within thecavity 31.' Provision is made, if required, for astrain cord 36 to be secured to the retaining clip at 0αe end and for a knot ornipple 37 at its other end to be retained in arecess 38 in the first insert, the strain cord passing through a slot, shown at 43 in Figure 7, in to thecavity 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 thecable 25 with retainingclip 35 andstrain cord 36. Theinserts protrusions mating recesses bush 32 and of thesecond insert 30 are conically tapered to ensure their axial alignment. One or more studs or protrusions (not shown) are provided on the inner surface of the rear cylindrical portion of thebody part 11 to provide loosely fitting guidance for thegrooves recess 27. - It will be apparent that 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:
- (a) The
circular retaining member 7 is inserted into the annular cavity of thefront part 11. - (b) The end of the
cable 25 is prepared such that theindividual cores 24 are suitable exposed with bared ends. - (c) The end of the cable, so prepared, is threaded in sequence through the
coupling nut 33, thethrust washer 34, the resilient''bush 32 and the retaining"clip 35. - (d) The retaining clip is secured to the cable, thereby preventing the cable from withdrawing through the resilient bush. A
strain cord 36 is secured to the clip at this time if required. - (e) The cable end is threaded through the
second insert 30 and each baredcore end 24 is threaded through theappropriate bore 28 in thefirst insert 11 and into the hollow end of acontact 13. - (f) The core ends 24 are crimped to the
male contacts 13. - (g)
Contacts 13 are fully pushed into thebores 28 such that their crimped ends are contained within thebores 28. If a strain cord is fitted, the cord is threaded into the slot 42 in thefirst insert 11 and a knot ornipple 37 in the strain cord is placed in therecess 38. - (h) The first and second inserts are mated together, with
studs 41A entering recesses male contacts 13 protrude at the front end. - (i) The ganged assembly is inserted into the
rear recess 27 of thefront part 11 whose internal protrusions loosely enter theslots male contacts 13 with thebores 12 in thefront part 11. The inserts are then lightly eased forward until thecontacts 13 enter thebores 12. - (j) The clamp nut is screwed to the rear of the
front part 11 and tightened. When the clamp nut is fully tightened, the thickenedportions 23 of thecontacts 13 have entered the counterbores of thebores 12 and thecontacts 13 are firmly supported. - It will be apparent that the above sequence of operations may be performed rapidly and requires less manual skill than prior art constructions, since the ganged assembly is self aligning and mechanically protects the cable cores while being inserted.
- The above embodiment of the invention has been disclosed by way of example, and alternative embodiments will be apparent to those skilled in the art.
