Definitions

  • This invention relates to quick-release, multiple pin electrical connector.
  • the electrical connectors that permit the release of the objects that carry them are of the direct connection type, wherein the pins are inserted into the socket by pushing along the longitudinal axis of the plug and are removed therefrom by simply pulling.
  • Locking means actuated also by the pulling, can be added to the connector to prevent the untimely release of its two parts.
  • the plug has a large number of pins, the force required to insert it becomes prohibitive.
  • the use of the bayonet and pin system considerably reduces the force required, thanks to the helical grooves associated therewith which cooperate with the rotational movement required by this kind of connector, it is this very movement that prevents quick uncoupling of the connector, making the bayonet method unusable.
  • An object of this invention is to obtain an arrangement that permits using the bayonet and stop system, or a similar system, with electrical connectors mounted on releasable objects, and requiring only a single rectilinear uncoupling movement, without concomitant rotation.
  • the apparatus of the invention relates to a pin and socket type electrical connector, comprising two separable, cylindrical, inter-locking parts, one of which separable parts carries at least one first fixed coupling element and the other of which separable parts has at least one second coupling element carried by a sleeve or a barrel rotatably mounted on the other part but incapable of longitudinal movement with respect to that part.
  • a locking sleeve for said movable elements is slidably mounted on said sleeve and has an internal longitudinal cross section comprising two steps, one of these steps having an internal diameter such that, when it engages the one or more movable coupling elements these latter are pushed inwards to cooperate with the one or more first coupling elements, and the second step having an internal diameter greater than that of the first step, such that when it is aligned with the one or movable coupling elements these latter are released and free to move outwards along radii; and means for pushing the one or more movable coupling elements back to their original position, after the two parts have been separated by a longitudinal pull.
  • the movable coupling elements can be each a ball or a cylindrical element that can move radially in an aperture in the rotatable sleeve.
  • FIG. 1 is a longitudinal, sectional view of a connector of the invention according to line AA of FIG. 2;
  • FIG. 2 is a transverse, sectional view of said connector along line BB of FIG. 1;
  • FIG. 3 is a partial, side elevational flattened view on reduced scale of the outer surface of one part of the connector, having bayonet grooves;
  • FIGS. 4 and 5 show the manner of operation of the connector of FIGS. 1 through 3;
  • FIGS. 6 and 7 are views in partial section taken along the axis of another embodiment of the locking parts respectively showing the locked and disconnected positions of the pins.
  • FIGURES 1 and 2 show an electrical connector of which the male fitting consists of a sleeve 1, preferably metallic, containing a block 2, made from a material that is electrically insulating, carrying one or more pins 3, whose number varies according to the intended use of the connector, said number being seven in the embodiment shown.
  • the outer surface of sleeve 1 contains helical grooves 4two in the embodiment shown-that constitute the female part of the standard beyonet coupling system (see also FIGURE 3).
  • the female part of the connector consists of a sleeve 5, preferably metallic, having therein an electrically insulating block 6 containing as many sockets 7 as there are pins 3 in the male fitting.
  • a barrel 8 fits over the sleeve 5 and is held thereon by an annular band or strap 9 carrying one or more rivets 10 whose shanks engage in an annular groove 11 provided in sleeve 5.
  • the barrel 8 has a number of openings 12 (two in the embodiment illustrated) of conical cross section for receiving balls 13, without allowing them to pass through, said balls being adapted to cooperate with the respective helical grooves 4 in sleeve 1 when they are caused to protrude on the inner surface of barrel 8 as will be hereinafter described.
  • the balls 13 are held in the openings 12 of barrel 8 by a sleeve 14- having two steps 14a and 14b.
  • a spring 15 press ng against wall 8a keeps the sleeve in the position shown in FIGURE 1, in which the balls 13 are held in by the first step 14a, which has the smaller diameter.
  • the diameter of the second step 14b is such that it permits the balls 13 to be completely released from the openings 12 of the barrel when the sleeve 14 is moved with respect to the barrel by pulling'on it in the direction of The pull can be obtained several tie points on the sleeve, whereby the balls can be freed from the openings, and the mechanism thus unlocked.
  • a longitudinal slot 70 opens at the free end of sleeve 5 and is adapted to receive a corresponding elongated key 71 secured on the inner surface of sleeve 1 along a generatrix thereof.
  • a longitudinal groove 72 is provided in the outer surface of sleeve 1, in which may engage an elongated key 73 secured in a recessed part of the outer surface of sleeve 5.
  • slot 70 and key 71 is greater than that of groove 72 and key 73, and the peripheral engagement position of key 71 in slot 79, and of key 73 in groove 72, respectively corresponds to the required engagement position of the pins 3 with the corresponding sockets 7, and of the respective balls 13 with the axial parts 40 of the corresponding grooves 4 (FIGURE 3).
  • sleeve 5 In connecting the male and female members, sleeve 5 is first axially engaged in sleeve 1, the relative angular position of said sleeves being such that key 73 of sleeve 5 engages groove 72 of sleeve 1 and key 71 of sleeve 1 engages slot 70 of sleeve 5, thus preventing any relative rotation between the male and female members as a whole. Said sleeve 5 is further pushed in sleeve 1, balls 13 engage the parts 40 of grooves 4, and pins 3 engage sockets 7. Once balls 13 have reached the end of said parts 4a of grooves 4, barrel 8 is rotated by hand with respect to sleeve 5. Balls 13 engage the helicoidal part of grooves 4 and sleeve 5 with all the members attached thereto is further pushed axially until complete engagement of the two members is obtained.
  • FIGURES 6 and 7 relate to a modification of the locking means between the male and female part of the connector, in which substantially cylindrical, lever actuated studs are substituted for the balls 13 for cooperation with the helical grooves in the outer sleeve of the male part.
  • the outer sleeve for the male fitting is shown at 31 and is thus externally provided with helical grooves 34.
  • the female member has a sleeve 35 with a barrel 38 rotatably mounted thereon and held by a band or strap 39.
  • Barrel 38 has a number of radial openings 42 each housing a stud 46 having an end 46a of reduced diameter, which cooperates with the corresponding groove 34, and a round head 46b.
  • barrel 38 is provided with a longitudinal groove 50 of which the middle plane passes through the axis of the corresponding opening 42.
  • a lever 51 pivoting on a pin 52 inserted in barrel 38 transversely of each groove 50, projects into a diameter groove 460 provided in the corresponding stud 46, under a pin 53 bridging said groove 46c.
  • Said lever 51 has a heel 51a cooperating with the inner edge 54 of an opening provided at the center of a toric cup 55 formed at the end of a sleeve 44 slidably mounted on the outer surface 56 of a ring 57. This latter ring is held on barrel 38 by means of a keeper ring 58.
  • a spring 45 inserted between the front wall 59 of sleeve 44 and ring 57, presses the sleeve towards the studs 46.
  • a cord 60 is slipped through a hole 61 provided in an ear 62 extending from sleeve 44.
  • Cord 60 may form a loop, for example, the other end thereof being connected in like fashion to a diametrically opposite ear of the sleeve 44.
  • This embodiment operates in the following manner.
  • sleeve 35 is slid over sleeve 31, as in the embodiment of FIGURES l-5.
  • the studs 46 which are held locked in the position of FIGURE 8 by the step forming slope of the cup 55 of sleeve 44, are slid along the helical grooves 34 by rotating the barrel 38 until they come to the end of said grooves 34.
  • the male and female members can be separated by reversing the movement.
  • a quick release connection device comprising a first and second separable, cooperating, connecting units, a first and second cylindrical outer tubular member rigidly secured on said first and second units, re spectively, and each having a longitudinal axis, said first tubular member having an outer surface and a projecting free end, at least one helical groove provided in the said outer surface, and opening at said free end of said first tubular member, reciprocally engageable means provided on said first and second tubular members, respectively, for preventing relative rotation about said longitudinal axis of said first and second tubular members when in engaged relationship, a sleeve rotatably mounted and held against axial movement on said second tubular member, said sleeve having a projecting free end having a substantially smooth outer surface, and an inner surface adapted to overlie the projecting free end of the said first tubular member, as many circumferentially arranged radial openings in said projecting free end of said sleeve as there are helical grooves in said first tubular member,
  • each locking member has a rounded head protruding on the outer surface of the said sleeve and the second section of the locking ring has a corresponding toroidal shape.
  • each said lever is arranged in a groove provided in the outer surface of the said sleeve and each locking member is cut axially to accommodate the front end of the corresponding lever, the upper surface of the front end portion engaging a transverse pin arranged within said locking member.
