Definitions

  • This invention generally relates to electrical connectors for use with multiconductor electrical cables and more specifically to shielded electrical connectors for use with shielded electrical cables.
  • Multiconductor cables are commonly used to interconnect electronic equipment. Cables interconnecting such equipment together as well as the equipment themselves often radiate unwanted electromagnetic radiations (EMR) that can interfere with other equipment as well as radio communications. These radiations are reduced significantly by covering the cable with a braided wire shield which is grounded thanks to shielded cable connectors connected to the equipment ground. Similarly, cables interconnecting some electronic devices can act as antennas that pick up unwanted EMR signals, and shielded cables are used to protect against such unwanted interferences.
  • EMR electromagnetic radiations
  • connection of the cable to the equipment requires a cable connector attached to the cable end portion.
  • a cable connector assembly also called a plug.
  • Such assemblies generally comprise additional features such as strain relief means for the cable to ensure proper retention of the cable within the housing as well as assembly integrity when for example the assembly is unplugged.
  • a cable connector assembly is known from US 4,272,148.
  • the strain relief means comprises a ferrule that securely clamps the cable.
  • Such a ferrule is provided with longitudinal slots that allow the cable plastic sheath to deform and flow into slots to prevent rotation of the cable.
  • Such a ferrule may plastically deform upon assembly of the plug, making it too fragile for a reliable cable connector assembly.
  • this ferrule is generally of a diameter barely greater than the cable sheath outer diameter, and can only be inserted on the cable from the tip of the cable end portion.
  • An object of the present invention is to provide an easy to manufacture cable connector assembly with reliable strain relief means.
  • a further object of the invention is to provide a cable connector assembly that is easy to assemble, with an easy to mount and resistant strain relief means.
  • An additional object of the present invention is to provide a connecter assembly with improved strain relief means that cannot damage the cable end portion.
  • the invention takes advantage of the two part retention means for easy assembly directly onto and around the cable end portion with no sliding of the strain relief means on the cable involved.
  • the tip of the cable remains clear of any contact with the strain relief means.
  • Fig. 1 represents a perspective view of the strain relief means of the cable connector assembly according to the invention, in an open state
  • Fig. 2 represents a perspective view of the strain relief means of Fig. 1 in a closed state
  • Fig. 3 corresponds to a perspective view of the cable before assembly with the strain relief means
  • Fig. 4 is a perspective view of the cable after assembly with the strain relief means according to the invention.
  • Fig. 5 corresponds to an exploded perspective view of the cable connector assembly in a first implementation according to the invention
  • Fig. 6 is a perspective view of the cable connector assembly in a first implementation according to the invention.
  • the cable connector assembly according to the invention allows connection of a cable 30 having one or more insulated conductors 31 covered by an insulating sheath 33. It should be noted that the present invention also applies to cables having non-insulated conductors.
  • the assembly comprises mating first 51 and second 52 shells connected together to form a cable housing.
  • the resulting cable housing has a cavity 50 formed therein, as seen in the exploded view of FIG. 5, between first shell 51 and second shell 52.
  • the cable connector assembly further comprises strain relief means 10 surrounding a segment of the cable, e.g. in the present case around a segment of the insulating sheath 33. Cavity 50 is adapted to retain strain relief means 10 when first and second shells are connected together.
  • the strain relief means 10 is shown in FIGs. 1 and 2. It comprises first
  • hinge means 15 may be an integral hinge formed on one pair of adjacent edges of first 11 and second 12 portions.
  • first and second portions 11 and 12 are both semi cylindrical shells. When assembled, they form a ferrule that surrounds a segment of sheath 33.
  • Both semi cylindrical shells 11 and 12 are adapted to clamp the cable when both shells 11 and 12 are assembled around the segment of sheath 33.
  • Ribs 18 are provided on the inner surface of both semi cylindrical shells for example through grooves 19 defined on these inner surfaces. Ribs 18 are provided to deform sheath 33, and therefore clamp cable 30 when ferrule
  • sealing means 16 and 17 are provided on both semi cylindrical shells 11 and 12 to seal and clamp ferrule 10 around cable 30, as seen in FIG. 4.
  • Sealing means 16 and 17 may be e.g. snap fit connection provided on edges of semi cylindrical shells 11 and 12 opposed to the edges carrying the hinged means 15.
  • grooves 180 are provided on the outer surface of at least one of the semi cylindrical shells. The grooves may be for example circular grooves as seen in FIGs. 2 and 4.
  • Such grooves are to cooperate with corresponding ridges provided on cavity 50 formed by mating first and second shells 51 and 52, so that ferrule 10 is tightly maintain in the cable connector according to the invention.
  • ridges are provided on at least one of the mating shells inner surface.
  • Ribs 18 as well as grooves 180 on ferrule 10 allow the cable 30 to be retained within the cable housing, preventing any rotation or translation of the cable.
  • a connector 20 is provided to receive the conductors 31 of cable 30 as seen in FIG. 5.
  • Connector 20 is to be located in an extension of cavity 50 and retained therein when mating shells 51 and 52 are connected together.
  • cable 30 has a plurality of insulated conductors 31 covered by an insulating sheath 33.
  • cable 30 is provided with conductive shield; e.g. a shielding braid, underneath insulating sheath 33 and surrounding the plurality of conductors 31.
  • conductive shield e.g. a shielding braid
  • a portion of sheath 33 is removed to expose the conductors 31 that are to be attached to connector 20.
  • the exposed braid may be shaped to form at least one strand 32, and preferably two as seen in FIG. 3.
  • Ferrule 10 is then clamped around the segment of cable 30 adjacent the segment with the removed sheath.
  • Semi cylindrical shells 11 and 12 surround tightly this segment, thanks to the ribs 18 and the sealing means 16 and 17.
  • the shielding braid or the strands of shielding braid 32 are folded onto the outer surface of ferrule 10, as seen in FIG. 4.
  • the cable end portion with the ferrule 10 is then ready for assembly with the mating shells 51 and 52. After conductors 31 are attached to connector 20, mating shells 51 and
  • ferrule 10 and connector 20 are placed on both sides of ferrule 10 and connector 20, with the cavity 50 and its extension facing the ferrule and the connector respectively.
  • Clamping means are provided on both mating shells to attach said mating shells together, therefore retaining ferrule 10 and cable 30 in a strain relief manner.
  • grooves 180 is to cooperate as seen earlier on with corresponding ridges on the mating shells inner surface.
  • the cavity 50 is adapted so that strands 32 come into contact with the inner surface of the mating shells 11 and 12.
  • clamping means are screws 511 and
  • first mating shell 51 and cooperating respectively with threaded holes 521 and 522 provided on second mating shell 52.
  • Other clamping means such as latch means may be provided to assemble and attach the mating shells together.
  • the mating shells 51 and 52 are shielded to electrically connect to the strands 32 of the cable 30.
  • Shells 51 and 52 may be plastic molded and metalized thanks to MID (molded interconnect device) techniques for example.
  • the connector 20 may also be shielded.
  • the strain relief means 10 may be plastic molded, and also metalized through MID techniques.
