Definitions

  • This invention relates to polarizing means for controlling matability between the main parts of separable electrical connectors having confrontable bores, and more specifically relates to removable members provided with portions adapted to register with.
  • Separable electrical connectors are employed in computer and control installations where receptacle connector parts are mounted on a panel adjacent to each other and the mating connector parts are connected to respective cables.
  • Means for correctly mating connector parts are shown in U.S. Pat. Nos. 3, 582,867; 3,611,272; 3,714,617 and 4,032,213.
  • the first two patents show a polarizing member having a base portion retained in a connector bore in a press- fit by ribs.
  • the latter patents disclose polarizing members which either require installation tools or require multiple pieces.
  • the invention proposes polarizing means for mateable units such as electrical connectors of the type having first and second engageable assemblies carrying mateable electrical contacts comprising a round bore disposed in the first assembly the a polarizing key removably mounted in the first assembly and a keyway disposed in the second assembly, the key and the keyway having opposite ends with one end of the key being interfitable within the keyway when properly oriented and in confronting relation on a common axis, an adjustable multi-sided base having top and bottom portions and a generally symmetrical transverse cross-section, said base extending from the other end of the key and adapted to be mounted in the first assembly bore characterized in that the polarizing means further comprises a plurality of projections extending outwardly from the sides of the base, each projection being longitudinally disposed between the top and bottom portions of and spaced from each other around the sides of the base, said bore in the first assembly including a plurality of slots extending outwardly therefrom and defining registrable positions for receiving the projections,
  • One advantage of this invention to provide polarizing members that may be inserted into a connector without the use of tools.
  • the invention thus provides a polarizing and guidance means which can be readily adjusted to provide a plurality of different polarizing positions.
  • a pair of interchangeable polarizing insert members having a key and a keyway respectively and adapted for an interference fit within bores confrontably disposed within respective plug and receptacle assemblies of a connector body.
  • Another advantage of the invention is the provision of a programmable keying and guidance device capable of positioning of a connector body so that it will mate only with a predetermined member.
  • Still another advantage of this invention is to provide a connector polarization and guide pin that can be rapidly installed in a plurality of desired positions in a connector body.
  • a further advantage of this invention is the provision of a polarizing insert having radially extended portions non-rotatably interfitted within a slotted bore of an assembly to be polarized.
  • the polarizing means (30) includes a polarizing pin (40) having a round multisided base (42) and a key (52) extending therefrom, a round multi-sided insert (60) having a base (62) with a keyway (72) disposed therein and a plurality of projections (50,70) extending radially outwardly from the sides of the bases (42, 62),each of the projections being longitudinally disposed between the respective top (43,63) and bottom portions (47, 67) and angularly spaced from each other around the sides thereof.
  • the multi-sided bases (42, 60) are adapted to be received in seats or bores (14, 24) disposed in the assemblies (10,20) of the electrical connector when brought into aligned confronting relation, the bores including a plurality of slots (16,26) radially extending outward therefrom.
  • the slots (16,26) define registrable positions for the projections (50,70), the positions permitting the polarizing pin (40) and the keyway (72) to be programmed to be disposed in any one of a number of different angular interfitable positions.
  • a cross-section of each respective bore and its associated slots is somewhat smaller than the cross-section of each base and its associated projections, thereby providing a tight interference fit therebetween.
  • each base is configured to be interchangeably fittable within either bore (14,24).
  • the plug assembly (10) may engage with the receptacle assembly (20). Engagement is achieved when the key (52) interfits within the keyway (72). When the key and keyway are not correctly oriented relative to each other, mating of the connector assemblies is prevented.
  • Figure 1 shows the assembled electrical connector (100), the assembled connector comprising the plug assembly (10) having a plug body (12) being mated with the receptacle assembly (20) having a receptacle body (22).
  • the polarizing pin (40) is shown properly oriented and mounted in the bore (14) of the plug body (12).
  • a plurality of (not shown) electrical contacts disposed in the plug body (12) interconnect with a plurality of (not shown) mateable contacts disposed in the receptacle body (22) when the two assemblies are fully mated.
  • the plug body (12) includes the inwardly extending bore or seat (14) for receiving the base (42) of polarizing pin (40), the bore (14) being axially aligned with and in confronting relation with the (not shown) keyway (72) disposed in the receptacle body (22).
  • the bore (14) is generally round and includes the plurality of slots (16) extending radially outward from the bore, each slot being angularly spaced from the other there-around, the bore and its associated slots having a generally symmetrical cross-section.
  • the slots (16) could be of any desired shape but are shown in Figure 1 as being generally semicircular.
  • the bore and its associated slots generally extend perpendicularly inward from a top surface(18) of the plug body(12).
  • Figure 2 shows the polarizing pin (40) in accord with the present invention and comprises the multi-sided base (42) and the key (52), the key (52) being secured to the base at one end (53) and extending therefrom to a free distal end (55), the distal end being insertable within the keyway (72).
  • the base (42) is round and includes the plurality of projections (50) which extend around the sides of the base in a spaced relation, each projection (50) being longitudinally disposed between a top (45) and a bottom (49) end surface of the base, the base (42) and associated projections (50) having a generally symmetrical transverse cross-section.
  • the key (52) of polarizing pin has a,transverse cross-section in the shape of a Y, each portion of the Y being disposed angularly nonsymmetrically relative to the other.
  • a transverse cross-section of the bore (14) and of the slots (16) associated therewith is somewhat smaller than the transverse cross-section of the base (42) and associated projections (50) of the polarizing pin (40), thereby providing a tight interference fit between the bore (14) and the sides of the base (42) and/or between the slots (16) and the projections (50).
  • Each slot (16) defines a registrable position for one projection (50).
  • the walls of the bore may or may not interferingly fit against the sides of the base (42) of the polarizing pin (40) depending on tightness of fitment desired.
  • Figure 4 shows the multi-sided insert (60) and comprises the base (62) having a cross section similar to that shown in Figure 3 for base (42) of the polarizing pin (40).
  • the insertable base portion (62) of insert (60) has a round transverse cross section, includes the plurality of projections (70) extending radially from the sides thereof and the Y-shaped keyway (72).
  • keyway (72) extends from a top end surface (65) the base (62) and into the insert.
  • the cross-section of the keyway conforms in shape to but is slightly greater in size than that of the key in order to permit a close clearance fitment between the two.
  • the polarizing pin (40) is shown in alignment with the bore (14) of the plug assembly (10), the multi-sided insert (60) having the keyway (72) in alignment with the second bore (24) of the receptacle assembly (20), the two bores (14,24) being axially aligned and in confronting relation and the key (52) on the polarizing . pin (40) properly oriented for fitment within the keyway (72) disposed in the base (62) of multi-sided insert (60).
  • the receptacle body (22) includes the second bore (24) and the second slots (26) extending radially outwardly therefrom, the second bore (24) being generally round and adapted to receive the base (62) of the multisided insert (60), the second bore and its associated slots having a generally symmetrical transverse cross-section and extending generally perpendicularly inward from a top surface (28) of the rece F l_. ⁇ le body (22).
  • the second slots (26) could be of any desired shape and are shown in Figure 6 as being generally semicircular.
  • a transverse cross-section of the second bore (24) and its associated slots (26) is somewhat smaller than the tranverse cross-section of the base (62) of the multisided insert (60) and its radially extending projections (50), the reduced cross-section providing a tight interference fit between respective slots (26) and projections (70) and/or the insert base (62) and bore (24).
  • Each of the second slots (26) define a registrable position for the second projections (70).
  • transverse cross-section of the base (42) of the polarizing pin (40), shown best in Figures 3 and 6 could be the same as the transverse cross-section of base (62) of the multi-sided insert (60) shown best in Figures 3 and 6, thereby allowing interchangeability between the bases (42,62) and permitting the polarizing pin (40) and/or multi-sided insert (60) to be received by either the plug (10) and/or the receptacle assemblies (20), respectively.
  • the polarizing pin could be prismatic and uniformly symmetrical in cross-section between the top and the bottom surfaces, the key having the shape of the base from which it extends.
  • the angular position of the respective projections and slots would be nonuniformly positioned angularly about the respective bores to provide the polarization, the difference in cross-section providing the interference fit.
  • the distal end (55) of the key (52) is chamfered (57) and provides a smooth guide to the key when entering the keyway.
  • the insertable bottom portions (47,67) of the base (42) and the multi- sided insert (60) are similarly chamfered.
  • the number could increase (decrease) depending on the number of positions desired.
  • the projections and slot need not be semicircular but could be rectangular, triangular, or some other shape.
