Definitions

  • This invention relates to electrical connectors, and in particular it relates to electrical connectors having means for reducing the possibility of the connector becoming disengaged due to vibration.
  • a previously proposed electrical connector comprises a plug, a socket, and a coupling sleeve mounted on the plug so that it can rotate about the longitudinal axis of the plug.
  • the coupling sleeve is arranged so that it can be screwed onto the socket thereby drawing the plug and socket together.
  • the coupling sleeve can secure the plug and socket together by way of a bayonet action.
  • an electrical connector comprising a socket part and a plug part, wherein one of the parts has a coupling sleeve rotatable thereon in one direction for coupling the socket part and the plug part together, characterised in that a thrust washer is disposed between the coupling sleeve and said one part, the thrust washer being provided with a ratchet-like means operative to permit rotation of the coupling sleeve in the said one direction with a lower torque than that required to effect rotation in the opposite direction thereby to resist decoupling of the plug and socket parts by rotation.
  • the thrust washer preferably comprises an annular washer part
  • the ratchet means may comprise a plurality of circumferentially disposed arms, one end of each arm being attached to the annular washer part and the end of each arm remote from the attached end being provided with a detent for engaging toothed formations on said one part.
  • the ratchet-like means enables the coupling sleeve to be rotated to allow connection of the plug and socket, but the coupling sleeve resists rotation in the opposite direction so that if the electrical connector is subjected to vibration, the thrust washer eliminates or at least reduces the possibility of the coupling sleeve rotating and causing the connector to become disengaged.
  • One of the parts may have a screw thread means on its outer surface and the coupling sleeve may have an internal screw thread means which is complementary with the screw thread means of said one part.
  • One of the screw thread means may be defined by a plurality of radially movable parts which are disposed circumferentially within the connector to engage the other of the screw thread means.
  • the radially movable parts are slidably located in circumferentially disposed apertures
  • the connector includes a retaining sleeve which is movable relative to the movable parts, so that when it is moved into one position, it restrains the movable parts from sliding so that they engage the other screw thread means when the plug part and the socket part are connected, and when moved into another position allows the movable parts to slide away from the other screw thread means, thereby enabling disconnection of the plug part and the socket part.
  • the movable parts may be operatively associated with the coupling sleeve and captive therein.
  • the movable parts may be arranged to lie equiangularly about the longitudinal axis of the connector so that they define the internal screw thread means of the other part and engage roots of adjacent threads of the other thread means.
  • the movable parts themselves may be in the form of elongate members which extend radially within the connector and may be rounded at either or both ends and each may be provided with a flange which engages with a seat on the coupling sleeve which limits the distance of travel of the sliding part in a radial direction.
  • the movable parts may alternatively be in the form of arcuate segments lying equiangularly about the longitudinal axis of the connector.
  • each of the arcuate segments is preferably provided with one or more projections on its inwardly curved surface, which projections are preferably in the form of part of a helical thread.
  • the helical threads of the movable parts together make up the internal screw thread means.
  • the outwardly curved surface of the movable parts is also provided with one or more projections or ribs which butt against the retaining sleeve when in said one position.
  • the coupling sleeve has circumferentially extending apertures which have at least one pair of opposite sloping sides.
  • the arcuate segments have corresponding sloping sides which co-operate with the sloping sides of the coupling sleeve to limit inward radial movement of the segments within the connector.
  • the retaining sleeve may be of an annular cross section and may be provided with one or more recesses or holes suitable for receiving one end of the movable parts, or for receiving the one or more projections or ribs of th F arcuate segments, so that when the retaining sleeve is moved into the said another position, the movable parts cai move radially outwardly to permit disconnection of the connector.
  • the retaining sleeve may be provided with a helical recess for receiving the elongate movable parts, which helical recess corresponds to the helical arrangement of the elongate movable parts.
  • the retaining sleeve may be urged to rest at the one position by means of a spring.
  • the spring may be positioned between the coupling sleeve and the retaining sleeve.
  • the coupling sleeve may include a flange which, when the two parts are disconnected, is sandwiched between a stop and a spring washer on said other part, whereby the spring washer urges said other part towards said one part when the two parts are connected together.
  • the connector may be provided with an indexing means.
  • the indexing means may be in the form of a guide for example, which projects at a point on the periphery of the one part, which guide corresponds with a recess in the periphery of the other part.
  • the retaining sleeve may be attached to a lanyard thereby enabling the one part and the other part to be remotely separated, by pulling the lanyard, whereby the retaining sleeve slides into said another position, thereby enabling the movable parts to slide into the holes or recesses or helical recess provided in the retaining sleeve.
  • the one part corresponds to the socket part and the other part corresponds to the plug part.
  • Embodiments of the present invention provide connectors which are compact and which facilitate rapid an ⁇ reliable decoupling of screw coupled parts. Further, the simple construction of such connectors increases their reliability during use under adverse conditions such as icing.
  • a connector in which a socket part 2 and a plug part 4 are coupled together.
  • the socket part 2 is of circular cross-section and has a screw thread means, in this case a helical screw thread 6, formed on its outer periphery at one end.
  • the socket part 2 houses a moulded block 8 of insulating material, which block 8 provides support for a number of conductive socket elements 10.
  • the plug part 4 comprises an inner shell 12 which is positioned within the socket part 2 and which houses a moulded block 14 of insulating material.
  • the block 14 supports electrical connector pins 16 corresponding to the conductive socket elements 10 of the socket part 2.
  • the electrical pins 16 are received by the conductive socket elements 10 thereby effecting electrical connection between the socket part 2 and the plug part 4.
  • a rubber sealing gasket 18 is provided on the inner surface of the socket part 2 to provide a seal between the socket part 2 and the plug part 4 when they are coupled together.
  • a coupling sleeve 20 is captive on the outer surface of the plug part 4 and has an internal screw thread means 22 which is defined by a plurality of elongate movable or sliding parts 24 having hemispherical ends.
  • the sliding parts 24 are slidably located in radially extending apertures formed in the coupling sleeve 20 and they define a helical path which corresponds to the helical screw thread 6.
  • the radially inward ends of the sliding parts 24 engage roots of the helical screw thread 6 when the socket part 2 and the plug part 4 are connected.
  • the radially outward ends of the sliding parts 24 butt against a retaining sleeve 26 which is slidably mounted on the coupling sleeve 20.
  • a thrust washer 30 (to be described in detail later with reference to Figures 8a, 8b and 9) is sandwiched between a stop 32 formed on the outer periphery of the inner shell 12, and a flange 34, which flange forms part of the coupling sleeve 20.
  • the thrust washer 30 urges the socket part 2 towards the plug part 4 when the two parts are coupled together.
  • This arrangement enables the coupling sleeve 20 to be captive on the plug part 4 so that it is free to rotate about the longitudinal axis of the connector. It will be appreciated that the foregoing arrangement is such that the coupling sleeve 20 can be screwed on to or off the socket part 2 by rotating the coupling sleeve about the longitudinal axis of the connector in the appropriate direction.
  • the thrust washer 30 is operative to permit rotation of the coupling sleeve 20 in the screw on direction with relative ease while being operative, by way of a ratchet-like means (to be described later), to resist rotation in the unscrew direction.
  • a lanyard 36 is attached to the retaining sleeve 26 in the manner shown.
  • the retaining sleeve 26 slides, relati ⁇ e to the coupling sleeve 20 and the sliding parts 24, in the direction of arrow A against the action of the spring 28.
  • the distance of travel of the retaining sleeve 26 is limited by means of a retaining pin 38 which passes through an elongate hole 39 in the retaining sleeve 26, which hole 39 defines the distance through which the retaining sleeve 26 may be moved.
  • the retaining sleeve 26 has been moved in the direction of arrow A so that one end of the hole 39 butts up against the pin 38, and a helical recess 40, formed in the retaining sleeve 26 (shown in Figure 1 as a pair of semi-circular recesses), is located adjacent to the sliding parts 24.
  • the sliding parts 24 are then free to slide radially outwardly when made to do so by shearing forces (due to the exertion of the force on the lanyard 36) between the hemispherical ends of the sliding parts 24 and the side of the helical screw thread 6.
  • the socket part 2 and the plug part 4 are shown to be disconnected, but a force is still being exerted on the lanyard 36 so that the retaining sleeve 26 remains in the appropriate position for disengagement of the socket part 2 and the plug part 4.
  • the thrust washer 30 expands and so causes the flange 34 of the coupling sleeve 20 to butt up against a retaining ring 42 located on the outer periphery of the inner shell 12, thereby preventing the coupling sleeve 20 from becoming detached from the inner shell 12.
  • the sliding parts 24 are each provided with a flange 44 which can engage with a seat 46 located in respective radially extending apertures.
  • the connector is provided with an indexing means so that the electrical pin 16 of the plug part 4 can be aligned with correct socket elements 10 of the socket part 2 when the two parts are to be connected.
  • the indexing means comprises a guide 48 which projects from the periphery of the plug part 4, and a recess 50 situated on the periphery of the socket part 2, which recess 50 receives the guide when the two parts are coupled together.
  • the electrical connector comprises a socket part 52 and a plug part 54 shown connected together.
  • the socket part 52 has an external screw thread 56 on its outer periphery.
  • a coupling sleeve 62 is captive on the outer surface of the plug part 54 and has an internal screw thread means which is defined by six arcuate movable parts 58 having projections 59 on their inwardly curved surface.
  • the projections 59 which although shown as having a hemispherical cross section may alternatively be trapezoidal in cross section, form part of a helical thread.
  • the projections 59 of the six movable parts 58 together make up a double thread having a triple thread start.
  • the movable parts 58 also have projections 60 on their outwardly curved surface.
  • the projections 60 are in the form of a pair of annular ribs which butt against a retaining sleeve 61 when the socket part 52 and the plug part 54 are connected together.
  • Each of the arcuate segments 58 is disposed in a circunferentially extending aperture in the coupling sleeve 62.
  • the retaining sleeve 61 is mounted on the outer surface of the coupling sleeve 62 and is slidable relative thereto in a direction parallel to the longitudinal axis of the connector and is rotatable about the longitudinal axis of the connector.
  • the retaining sleeve 61 has a pair of recesses 63 which correspond to the projections 60 of the arcuate segments 58.
  • the retaining sleeve 61 is located in a radial direction by means of an end cap 65 which is screwed and locked to the coupling sleeve 62 by means of a screw thread 65a.
  • the outer circumferential surface of the end cap 65 is knurled thereby facilitating an improved hand gripping surface.
  • a spring 68 (to be described in further detail later) is disposed between the retaining sleeve 61 and the coupling sleeve 62.
  • the spring 68 urges the retaining sleeve 61 towards the position shown in Figure 4 so that in the absence of a force in the direction of the arrow A, the retaining sleeve 61 restrains the arcuate segments 58 from moving radially outwardly and hence the electrical connector remains connected.
  • a thrust washer 66 (to be further described later) is located between the coupling sleeve 62 and the plug part 54.
  • the thrust washer is provided with a ratchet-like means operative to permit rotation of the coupling sleeve 62 in one direction with a lower torque than that required to effect rotation of the coupling sleeve in the opposite direction.
  • a circlip 67 is located into a recess formed in the coupling sleeve 62, which circlip serves to secure the thrust washer 66, and the coupling sleeve 62 in position.
  • a lanyard attachment ring 90 is positioned within a radially inner surface of the retaining sleeve 61 as shown in Figure 4.
  • a lanyard 70 is fixed to the lanyard attachment ring 90.
  • An end portion 69 of the retaining sleeve 61 is spun over so as to captivate the lanyard attachment ring 90 whilst allowing the retaining sleeve 61 to rotate relative to the ring 90. This ensures that the lanyard 70 always remains in the same attitude relative to the plug part 54.
  • FIG. 5 an end view of the coupling sleeve 62 is shown taken from the direction of an arrow B of Figure 4.
  • the coupling sleeve 62 has an inwardly directed flange 71 which has four slots 72 disposed along its circumference, which slots allow the thrust washer 66 and the circlip 67 to be put into position.
  • the coupling sleeve 62 has six circumferentially extending apertures 73 which correspond in size to the arcuate segments 58.
  • Each of the apertures 73 has a pair of opposite sloping sides 74 which cooperate with a pair of sloping sides 74a of the arcuate segment 58 so as to limit inward radial movement of the segment 58 when disposed within the apertures 73 of the coupling sleeve 62.
  • Figure 7a shows a plan view and Figure 7b shows a side elevational view of the spring 68.
  • the spring 68 may be formed from, for example, piano wire and may consist of five lobes, each lobe having a pair of sloping surfaces 75a and 75b of different lengths. The length of the surfaces 75a and 75b of each lobe may vary from one lobe to another, but the height 'a' of the spring along its circumference preferably remains constant.
  • the above described arrangement has the advantage that the arcuate segments 58 for use therein can be manufactured more easily.
  • the segments 58 can ee cut from an annular shaped brass ring after the projections 59 and 60 have been machined thereon. Manufacturing the arcuate segment 58 in this manner enables their thickness in a radial direction to be significantly reduced and hence the thickness of the coupling sleeve 62 can also be reduced. This results in an overall reduction in the overall radial dimension of the electrical connector.
  • arcuate segments 58 has the advantage that twisting of the segments 58 within the apertures 73 is eliminated or at least reduced thereby increasing the life of the connector. Further, the risk of the segments 58 becoming jammed is eliminated or reduced.
  • the lanyard attachment ring 90 By locating the lanyard attachment ring 90 on the radially inner surface of the retaining sleeve 61, unhampered hand access to the end cap 64 is possible thereby enabling the plug parts of the electrical connector to be secured onto the socket part 52 more easily. Further, by allowing relative rotation of the retaining sleeve 61 with respect to the lanyard attachment ring 68, the lanyard 70 is prevented from becoming tangled with the cable of the plug part 54.
  • the projections 59 in the form of a double thread with a triple thread start enables the plug part 54 to be connected to the socket part 52 with less than 180° turn by hand.
  • Figures 8a and 8b respectively show end and side elevational views of the thrust washer 66 (also equivalent to the thrust washer 30 of Figures 1 to 3).
  • Four elongate arms 80 are located around the outer periphery of an annular washer part 81 to form a ratchet-like means but any number of arms may be provided in alternative embodiments.
  • Each arm 80 is attached to the annular washer part 81 at one end, and at the end remote from the attached end, there is disposed a restraining portion or detent 82.
  • the restraining portion 82 is arcuate in shape and is formed integrally with the arm 80.
  • the restraining portion 82 can be triangular in shape, the precise shape and size being determined by the torque characteristics required.
  • Figure 9 shows an enlarged portion of one of the arms 80 when in contact with the plug part 54.
  • the plug part 54 has a toothed edge on its outer edge which can be of the form shown in Figure 9.
  • the thrust washer 66 When the thrust washer 66 is in the position as shown in Figure 4, the restraining portion 82 of the arms 80 engage with the toothed edge of the plug part 54.
  • the arms 80 are received by the slots 72 of the coupling sleeve 62 and hence relative rotation between the thrust washer 66 and the coupling sleeve 62 is restrained.
  • a similar toothed edge (not shown) is provided on the plug part 4 of the embodiment illustrated in Figures 1 to which edge co-operates with the thrust washer 30 to provide the required rotation characteristics.
  • the thrust washer 30, 66 as described above has the advantage that the coupling sleeve 62 is prevented from uncoupling if the connector is subjected to vibration.
  • the arms 80 may be of differing lengths, thereby eliminating or reducing the number of resonant frequencies of vibration of the thrust washer 66.
  • the lengths of the arms 80 are preferably such that vibrations over a wide frequency range will not cause the coupling sleeve 62 to work loose.
  • the annular washer part 81 may also act as a spring, shaped so as to urge the circlip 67 and the face of the plug part 54 apart.
