Definitions

  • the invention relates to a cable clamp for a multi- Contact electrical connector of the type comprising a shell and an insert within the shell. Contacts are mounted in cavities extending through the insert which has a radially displaceable element. A camrning ring on the external surface of the shell can be rotated to a locked position to shift the insert element and render the cavities tortuons thereby to lock the contacts in the cavities.
  • the present invention comprises a cable clamp which can be mounted on the shell only when the camming ring is in the locked position. Presence of the cable clamp on the connector shell thereby certifies that the contact terminals are retained and locked in the connector insert.
  • This invention relates to multi-contact electrical connectors.
  • One common type of multi-contact electrical connector comprises a metallic shell or housing, an insulating insert in the housing, and a plurality of contact terminals contained in the insert with the wires, which are secured to the terminals, extending rearwardly from the shell; Connectors of this type are adapted to be engaged with, and disengaged from, a complementary connector thereby to engage or disengage the contact terminals in the connectors.
  • a cable clamp which serves as a strain relief device for the wires, is mounted on the shell at the rear-ward end thereof.
  • the cable clamp serves to clamp the wires at a location adjacent to the shell so that if these wires are pulled when the two connectors of the connector assembly are de-coupled, the resulting tensile forces will be transmitted from the wires through the clamp to the shell and the contacts themselves will not be subjected to tensile forces.
  • VThe present invention relates specifically to an improved cable clamp or strain relief for an electrical connector and particularly, but not exclusively, to a cable clamping device for a connector of the type disclosed and claimed in the co-pending application of Clarence Leonard Paullus et al., Ser. No. 567,331, liled Oct. 20, 1966.
  • the two connectors of the connector vassembly are each provided with a camming ring rotatably mounted on the external surface of the shell. This camming ring controls the position of a shiftable insert grommet which, in turn, locks the contacts Within the insert assembly.
  • the cable clamp of the present invention cooperates with a rotatable camrning ring of the type shown in the Paullus et al, application to prevent rotation of the ring when the cable clamp is mounted on the shell.
  • the advantage of such an arrangement is that after the contact terminals have been mounted in the insert assembly and the shiftable insert grommet has been moved to its locking position for the terminals, the cable clamp can vbe positioned on the shell ICC to serve the functions of preventing rotation of the camming ring and transmitting the tensile forces applied to the wires directly to the shell.
  • the present invention also relates to a cable clamp which can be assembled to the connector after the contacts have been assembled to the connector insert.
  • a cable clamp which can be assembled to the connector after the contacts have been assembled to the connector insert.
  • the wires extending from the contacts need not be threaded through the cable clamp prior to their being mounted in the connector insert.
  • This feature of the invention is not directly related to connectors of the type shown in application Ser. No. 567,331.
  • a clamp in accordance with the invention can be used in connectors of types other than the type shown in application Ser. No. 567,331.
  • a further object is to provide a cable clamp which prevents rotation of a camming ring mounted on the shell of the connector.
  • a further object is to provide a cable clamp which can be assembled to the shell after all of the contacts have been mounted in the insert of the connector and which thus avoids the necessity of threading the contacts and the wires through the clamp.
  • a cylindrical cable clamp formed in two semi-cylindrical sections.
  • the adjacent sides are provided with radially extending lianges or ears through which suitable fasteners extend to secure the sections in assembled relationship.
  • the forward end of the clamp is provided with circumferentially spaced-apart bosses which are adapted to enter correspondingly spaced-apart openings in the rearward end of the shell, the arrangement being such that the sections of the cable clamp can be secured to the shell by positioning the bosses in the openings.
  • the forward end of the clamp also serves the :function of preventing rotation of a camming ring mounted on the connector shell when the clamp is in position by virtue of its position on the shell relative to a lock washer which abuts the camming ring.
  • the clamp thus prevents tampering with the camming ring and/or accidental removal of the contacts when it is in position on the shell.
  • FIGURE 1 is a sectional side view, with parts broken away, of a connector and cable clamp in accordance with the invention
  • FIGURE 2 is a fragmentary sectional side view similar to FIGURE 1 but showing only the left-hand portion of the connector with the cable clamp improperly mounted on the shell and with the parts shown in the Vpositions they occupy when the contacts are not retained;
  • FIGURE 3 is a perspective view of a connector cable clamp in accordance with the invention.
  • FIGURE 4 is a perspective view of one section of the clamp of FIGURE 3;
  • FIGURES 5 and 6 are views taken along the lines 5-5 and 6 6 of FIGURE 1;
  • FIGURE 7 is a side View of an alternative embodiment of the invention.

  • the connectors 4a, 6a comprise outer cylindrical shells 4, 6, the shell 4 having a forwardly extending hood 8 which projects over the mating end of shell 6.
  • the two connectors are coupled and de-coupled by means of a locking ring 10 which is rotatably mounted on the section 6 and which has a spiral groove 12 on its underside into which a pinV 14 on the hood portion 8 extends.
  • the locking ring 10 is retained in position on the shell section 6 my means of a circumferential ange 16 on the shell section 6 and a lock washer 20 on the locking ring.
  • a spring washer 18 is interposed between the flange 16 and the lock washer 20 to bias the ring leftwardly in FIGURE 1.
  • a composite insert assembly is mounted in the shell of the section 6, this insert assembly comprising an interface sealing grommet 22, a pair of relatively firm grommets 24, 26, a relatively soft, thin, elastically deformable grommet 28, an adjacent hard grommet 30, an additional soft grommet 32 and a back grommet 34 which is, again, of relatively firm material.
  • the grommets 24, 26, 30, and 34 are advantageously of a firm epoxy resin or of a material having similar physical properties.
  • the grommets 22, 28, 32 are of a suitable soft and yieldable insulating material such as neoprene rubber.
  • most of the interfaces between adjacent grommets and between the peripheries of the grommets and the internal surfaces of the shell are sealed with suitable adhesives.
  • the grommet 28 is bonded to the grommet 30 at their common interface 29 in a manner such that the grommet 30 can be displaced laterally, as in apparent from a comparison of FIGURES l and 2, without failure of bond.
  • Registered openings extend through the several grommets of the insert assembly to form cavities 36.
  • Contact terminals 38 are mounted in these cavities with the rearward ends of the terminals being disposed in the soft grommet 28 and forwardly of the interface 29.
  • the wires 37 which are secured as by crimping to these contacts extend leftwardly through a portion of the grommet 28, and through the grommets 30, 32, 34.
  • the grommet 30 has diametrically opposed radially projecting ears 40, 42 (FIGURE 2) which extend through axial slots 44 in the shell 6. These ears bear against an eccentric (with respect to the connector axis) camming surface 48 of a rotatable camming ring 46 mounted on the shell 6 adjacent to its rearward end.
  • the camming ring 46 is rotated until the portion of each cavity lying in the grommet 30 is in axial alignment with the portions of the corresponding cavities in the remaining grommets of the insert.
  • the contact terminals can then be inserted until their rearward ends are in the soft grommet 28 as shown in FIGURE 2.
  • the camming ring 46 is provided with a pair of diametrically opposed notches 50, 52 extending inwardly from its left-hand side as viewed in FIGURES l :and 2.
  • the notch 50 is relatively deeper than the notch 52 for reasons explained below.
  • a split spring washer 54 is mounted on the shell 6 adjacent to the left-hand side of the camming ring and has a radially projecting ear 58 adjacent to its gap.
  • the underside of the washer adjacent to the ear is cut away as shown at 60 (FIGURE 4) and the washer is seated in a suitable circumferential groove 56 on the shell 6.
  • the arrangement is such that the ear 58 is normally disposed in either of.
  • the notches 50, 52 although this ear can be resiliently moved leftwardly and unseated from either notch to permit manual rotation of the camming ring.
  • the washer thus serves to both retain the camming ring on the shell and to latch the ring in either position of rotational adjustment.
  • ear 58 when ear 58 is seated in notch 50, the ear will be co-planar with the remaining portions of the split ring and will be as remote as possible from the end of the shell. On the other hand, when the ear 58 is disposed in the shallow notch 52, this ear will be held somewhat closer to the end of the shell by the camming ring than when it is in the ear 50.
  • the cable clamp is formed in two sections 64, 66, each section being semi-cylindrical and complementary to the other section. Laterally extending flanges 68 are provided on the adjacent edges of the sections, one of these flanges of each section being provided with a threaded hole While the other flange is provided with an inwardly directed slot for the accommodf tion of screws 70 by means of which the two sections can be clamped together. These flanges 68 are slightly spacedapart intermediate the ends of the clamp but abut each other as shown at 69 adjacent to the rearward end of the clamp.
  • Each section is also provided with a tangentially extending ear 72 at its rearward end which extends past the surface of the adjacent section when the clamp is assembled.
  • the forward ends of the sections 64, 66 are flaired as shown at 74 to provide an enlarged cylindrical end 76.
  • the inside diameter of this end of the clamp is such that it will t over the end the shell 6.
  • Two inwardly directed bosses 78 are provided on each section 64, 66 in the cylindrical portion 76, these bosses being angularly spaced apart by
  • the bosses V78 are adapted to enter rectangular holes 80 in the rearward end of the shell 6, the holes 80 being also spaced apart by 90.
  • the holes 80 are disposed between the split washer S4 and the end of the shell and the split washer itself is located relatively close to the rearward end of the shell 6.
  • the camming ring In use, the camming ring will be in the position of FIGURE 2 with ear 58 seated in shallow notch 52 while the contacts are being inserted into the insert assembly. After completion of this inserting step, the technician should rotate the camming ring through an angle of to the position of FIGURE l before assembling the cable clamp to the shell in order to retain the contacts in the insert assembly.
  • the two sections 64, 66 of the cable clamp are then positioned around the conductors and the screws 70 of each section are partially tightened.
  • the ears 72 serve to gather the conductors and retain them in the clamp during this assembling procedure.
  • the clamp is then moved to the rearward end of the shell and the bosses 78 ⁇ are located in the holes 80.
  • the screws are then fully tightened to clamp the conductors extending from the wires.
  • the end of the cable clamp prevents rearward movement of the ear 58 so that it is impossible to move the camming ring to the unlocked position when the cable clamp is assembed to the shell.
  • the arrangement of the bosses 78 and the openings of the disclosed embodiment of the invention is such that it might be possible to'imperfectly mount the cable clamp on the shell when the ear 58 is seated in the shallow notch 52 of the camming ring.
  • Alternative arrangements within the scope of the invention might be employed.
  • the notch 52 could be eliminated entirely and the width of the camming ring could be increased to a greater thickness than that shown in the drawing at a location opposite to the location of the notch 50.
