Definitions

  • the present invention relates to electrical connector assemblies. Electrical connectors are often closely mounted on the back face of racks of electronic equipment. With high packing densities it may be difficult to remove or connect a connector assembly which may be surrounded by other connector assemblies.
  • a housing is arranged to hold a plurality of contacts in alignment, said housing having a plurality of channels spaced apart therein and longitudinal of the direction of insertion of the contacts, said channels each having an aperture at the rear of the housing and the termination of said channels being towards the front of the housing such that a tool having a plurality of arms correspondingly spaced apart and attached to a planar member may be used to facilitate the connection of the assembly to another assembly by inserting the arms in the channels to provide a grip at a distance from the rear of the housing.
  • each of the channels has a deepened section along a part of the length thereof and towards the respective terminations thereof arranged to provide a partial termination towards the apertures such that a disengagement tool having arms correspondingly spaced apart and having locking members attached thereto may be used to facilitate the disconnection of the assembly from another assembly by co-operation of the key members with the respective partial terminations of the channels.
  • a disengagement tool for use with a connector assembly as described in the preceding paragraph has at one end a plurality of arms spaced apart and arranged for insertion in a correspondingly spaced apart plurality of channels in a connector housing, and at the other end a hand-grip, each of said arms having a member extending at an angle to the direction of insertion as aforesaid and said members being arranged to co-operate with respective terminations in channels of a connector housing under the influence of the resilience of the material of the arms to effect a disengageable connection between the tool and a housing to permit the tool to be used to assist disengagement of a pair of mating connectors.
  • extension members extend in opposed directions and may be arranged to face each other inwardly of said arms.
  • the arms may be arranged to have a scissor action relative to the handle, the scissor action being dependent upon the flexibility of the plastics material of the tool.
  • the scissor action may be assisted by providing three channels in the moulding arranged with one channel central of the width of the moulding towards the rear of the arms and the other channels at an angle to the first channel towards the handle of the moulding.
  • the tool may be arranged such that pressure on a side of the moulding towards the handle section causes the key sections to move apart to permit disengagement of the tool from a housing to which the tool is attached.
  • the housing comprises eighteen segments 1 and 2 of two kinds arranged in two parallel rows of nine segments each.
  • Each segment is arranged to hold one electrical contact which is fitted by sliding insertion, shoulders of the contact being inserted into channels 3 provided at the rear of the segment.
  • a contact is fully inserted in one of the segments 1, 2 a key member of the contact springs into position through an aperture 4 to prevent the contact from sliding out.
  • the insertion tool 19 has a pair of arms 20 arranged to co-operate with a pair of channels 21 disposed in the ends of the housing.
  • the insertion tool 19 is moulded from for example a plastics material and, in use, the arms 20 slide into the channels 21 until the front of the arms reach the end of the channels.
  • the arms 20 of the insertion tool 19 have a thinner cross section than the body which in dependance on the resilience of the plastics material allows a limited amount of movement of the arms such that small variations in the separation of the channels 21 between connectors may be accommodated. It is here noted that the separation of the arms 20 is marginally less than the nominal separation of the channels 21 so that when a connector is being fitted using the tool it is firmly gripped.
  • the female connector assembly previously referred to may be fitted to its male counterpart even if there is insufficient space for the housing to be gripped by hand.
  • the insertion tool is provided with a thickened section 22 at the opposed end to the arms 20 to facilitate the withdrawal of the tool and to provide a grip when the tool is in use for engaging a connector assembly.
  • the channels 21 each have a deepened section 23 which provides a back wall 24 in the housing to facilitate disengagement of the connector assembly from its counterpart.
  • the disengagement tool comprises a pair of arms 25, spaced apart each of which has an inwardly extending section 27.
  • the arms 25 are inserted in the channels 21 and as they are pushed into engagement the wedge shaping of the front of the section 21 causes the arms 25 to open.
  • the opening of the arms 25 being dependent on the resilience of the plastics material from which the tool is moulded may cause the plastics material to crack.
  • three channels 26 are provided in the moulding which whilst retaining the tension which maintains the arms 25 in their usual closed position permits a scissor like action when the sections 27 are inserted into the channels.
  • the channels 26 are terminated in a thickened section 28 of the moulding to give added strength. To prevent the channels 26 from extending by cracking of the plastics material the channels are terminated with a circular section 29.
  • sections 32 are provided which come into contact with the body of the handle section to limit the movement provided by the scissor action.
  • a thickened guard section 33 is provided. This prevents excessive pressure on the fingers of the user.
