Definitions

  • An electrical plug made from a hollow housing, a body member within the housing, and two half-shell members attached to one end of the housing.
  • the body member has a projection extending from one end thereof between the half-shell members with a transverse alignment bore in the projection.
  • Each half-shell member has a corresponding alignment bore, and the three parts are secured together by a bolt passing through the three alignment bores.
  • the half-shell members are aligned with respect to the housing by means of beads on the interior surface of the half-shells which engage a recess in the exterior surface of the housing.
  • the invention relates to electrical plugs consisting of an insulating body containing electrical sockets or prongs, a housing surrounding the insulating body, and two halfshells attached to one end of the housing to receive electrical conductors.
  • Connector sockets are known whose insulating bodies are constructed of two identical halves. These halves contain recesses in which the sockets, together with their connecting leads, are disposed. Both halves of the insulating body are held together by means of a screw and a nut.
  • the above-noted object of the invention is achieved by providing a projection on the insulating body which extends between the two half-shells, with a transverse alignment bore in the projection and a pair of matching transverse alignment bores in the two half-shell members, and beads on the inner surface of the two half-shell members to engage a recess on the outer surface of the housing.
  • the assembly is held together by a bolt passing through the three transverse alignment bores.
  • a coaxial guide channel is provided in front of each contact socket, and a pair of spring loaded slides close the front of the sockets to prevent dirt from entering.
  • the front surface of each slide is beveled so that the slide will be pushed aside when prongs are inserted into the sockets.
  • FIGURE 1 is a plan view of one body member of the invention in partial cross section.
  • FIGURE 2 is a plan view of the body member of 3,451,036 Patented June 17, 1969 for use in combination with the plug shown in FIG- URE 2.
  • contact sockets 1 are selfcleaning multiple safety contacts with independently flexi- 'ble individual contacts, and are floatingly connected by means of screws 2 within an insulating body 3.
  • the insulating body contains, on the side toward the connecting lead, a projection 4 with a transverse alignment bore 5.
  • a coaxial guide channel 6, which in its rest position is closed by slides 7, is disposed in front of the contact sockets. Slides 7 prevent dirt from entering the contact sockets.
  • the slides 7 are pushed by the plug prongs 8 (FIGURE 3) under pressure of the springs 9 into a transverse channel 10.
  • the displacement of slides 7 is facilitated by the beveled top surface 11 of the slides.
  • the plug prongs 8 When the plug prongs 8 are inserted, the slides come to rest against indentations 12 in the plug prongs and thus provide a mechanical safety lock, which can be manually disengaged by applying sufiicient withdrawal pressure to the prongs.
  • the essentially cylindrical socket insert 13 (FIG- URE 1) is inserted from the rear into a hollow housing 14 (FIGURE 2). There, socket insert 13 rests against a frontal, inwardly directed collar (not shown in the drawings). Then, the upper half-shell 15, into whose bore 16 a hollow rivet 17 with a nut 18 attached thereto had previously been attached, is placed with its bead 19 in the recess 20 of the housing. Subsequently, the lower half-shell 15, which is identical to the upper half-shell 15, is also placed with its bead in the recess of the housing.
  • the machine screw 21 is placed through the bore of the lower half-shell 15', through the bore 5 and through the bore 16 of the upper half-shell 15 and is screwed into the nut 18.
  • the upper ends of the half-shells are shaped to provide a lead wire clamp for the lead wire, and pressure is applied to this lead wire clamp by machine screw 21.
  • the housing is provided, on its plug-insertion side, with a protective collar 22 which receives the insulated base 22' of the plug 23.
  • An electrical plug comprising, in combination:
  • each of said half-shell members having a bead on the interior surface thereof near one end thereof for engagement in said annular recess, and each of said half-shell members having a transverse alignment bore;
  • (D) means passing through the three transverse bores, while the same are in alignment with each other and while said beads of said half-shell members are received in said recess for securing said two halfshell members, said housing member, and said body member together to form a unified electrical plug.
  • An electrical plug as defined in claim 1, wherein said means passing through the three transverse bores comprises a machine screw and a nut.
  • An electrical plug for use in combination with the electrical plug defined in claim 9, comprising a second 5 body member, two prongs joined to said second body member and projecting therefrom, said prongs being positioned to engage said contact sockets in the first mentioned body member, and indentations in said prongs for engaging said slides when said prongs are inserted into said contact sockets.
