Definitions

  • FGURE 1 is an exploded perspective view illustrating a connector embodying principles of this invention
  • FIGURES 2 4 are plan views of the connector shown in FIGURE 1 illustrating various stages of assembly
  • FIGURE 5 is a plan View, partially broken away, showing the connector of FIGURE l prior to being fitted into a block;
  • FIGURE 6 is a view similar to FiGURE 5 illustrating the connector assembled in the block
  • FlGURE 7 shows a pair of mating blocks with connectors therein
  • FIGURE S is an exploded view similar to FIGURE 1 illustrating the assembly for retaining the connector in the block.
  • FIGURE 8A is a view similar to FIGURE 8 illustrating the female element in the connection.
  • the male element A of an electrical connection may include a pin it), with a retaining sleeve 12, wire receiving means 2li and a seal-receiving means 22, a resilient sealing element 16 and the conductor 18.
  • the female element is identical except for a receptacle l1 instead of the pin Iii, FIGURE 7 and FlGURE 8A, and need not be described.
  • the wire receiving portion includes a wire receiving ferrule 2t) which accommodates a bare wire 18 and is adapted to be crimped thereto.
  • a seal receiving ferrule 22 exten-ds from the wire receiving ferrule Ztl at a short distance from one end thereof and is concentric therewith.
  • the space between :the end of the Wire receiving ferrule 2@ and the seal receiving ferrule 22 accepts one end of the resilient sealing member 16 (which may be stepped for easier insertion).
  • the wire receiving ferrule 2d is outwardly tapered (eg. by a mandrel) so that it securely grasps the seal therein, as shown in FIGURE 3.
  • a conductor 18 is inserted into the assembly so that the uninsulated end of the conductor is positioned within wire receiving ferrule 20 and the insulation on the wire abuts the projecting end of the ferrule (note FIGURE 4).
  • the wire receiving ferrule 2t) is then crimped onto the conductor IS and the seal receiving ferrule 22 is deformed slightly (FIGURE 4) so as to cooperate with the tapered end of the wire receiving ferrule Zii to grasp the resilient member in secure gripping relationship.
  • the pin 1d has a pair of spaced lianges 24 and 26 of diiferent diameters on shank 28 which has a reduced portion 3l).
  • the pin retaining sleeve l2 may be formed of this iiat stock and curled around the shank 2%, with an open seam to provide a degree of resiliency.
  • the pin retaining member 12 is bulged outwardly with tabs 32 struck in one end thereof. As shown in FIGURES 5 and 6 the member 12 is seated between the flanges 24 and 26.
  • the blocks to be joined include a rigid member 42 having a plurality of male connectors therein and a corresponding block eti having an equal number of receptacles (to avoid repetition, only one set of connectors is shown in FIGURE 7).
  • the blocks are adapted to mate and a resilient seal M- is provided therein.
  • a peripheral seal d may surround the juncture of the mating surfaces of the blocks.
  • Each block has a plurality of apertures d3 (FIGURES 5 and 6) each having a diameter slightly larger than the flange 26 but smaller than the major diameter of the resilient seal l5. Within each aperture d8 is a portion 34 having a reduced diameter so that the tab 32 and the ilange Z6 locate the connector assembly in its proper assembled position, note FIGURE 6.
  • the tapered nose on the forward end of the pin retaining member i2 permits it to be contracted for insertion into the reduced portion 34 ⁇ of the aperture siti (FIGURE 5).
  • the pin retaining member l2 After the pin retaining member l2 has passed through the reduced portion 34- it again expands outwardly so that the tabs 32 and the llange 26 restrain longitudinal movement of the assembly.
  • the reduced portion 34 retains the shank 28 and the sleeve 12 in firm engagement due to the springiness of the metal stock.
  • the resilient seal llo has a major diameter 3S slightly rounded at 3e so that it will iit into the aperture in the block. Since the aperture is smaller than the major diameter 35 of the resilient sealing means le, the seal will be compressed and longitudinally extruded, as shown in FIGURE 6. This effects a sealed connection which firmly grasps the wire by compression and protects the connection against the intrusion of moisture.
  • the two blocks are joined and peripherally sealed as shown in FIG- URE 7.
  • a device Vof the character described including: a shank with a pair of spaced anges, said shank having a reduced diameter portion, a radially expandable sleeve surrounding said shank, said sleeve being tapered toward the reduced diameter portion of the shank, at least one tab on the sleeve in the area of the reduced diameter portion of the shank, a ferrule adapted to be crimped onto a conductor extending from the major ⁇ diameter portion of the shank, means for sealing the conductor against the intrusion of moisture, comprising a resilient sealing member held in compression on lthe conductor at least at its front juncture iwi-th tie ferru-le, and means on the shank for etecting an electrical connection, a rigid member having an aperture therein, said device adapted to lit the aperture in the rigid member, and said tab frictionally engaging the inner surface of said aperture, said aperture being counterbored at each end sothat the minor diameter is larger than the diameter of the shank but
