Definitions

  • This invention relates to a sealed insulation displacement connector.
  • the objects of this invention have been achieved by providing a connector having insulation displacement contacts therein, a base member and a cover member having wire mounting means for mounting electrical wires thereto, the cover member fixable to the base member such that electrical connection is made between the wires and the IDC contacts, characterized in that wire sealing means are provided between the cover and the wire, and elastomeric cover sealing means are provided between the base and cover members such that the electrical connection is completely sealed off from the exterior.
  • branch connector 2 for electrical connection to conducting wires 4.
  • the branch connector 2 comprises a base member 6 and cover members 8.
  • the base member 6 comprising a stamped and formed sheet metal conductor 10, an insulative housing 12, and sealing means 14.
  • the conductor 10 comprises a substantially flat interconnecting base portion 16, insulation displacement contact portions 18 in parallel and juxtaposed manner upstanding from the interconnecting portion 16, and an exterior contact portion 20 having a bolt or rivet hole 22.
  • the insulation displacement contact (IDC) portions 18 comprise a pair of opposing upstanding IDC walls 24 comprising slots 26 for receiving the electrical conducting wire 4 and making electrical contact therewith.
  • the housing 12 comprises compartments 28 having a base wall 30, and upstanding side walls 32, a back wall 34 and an opposing wire receiving front wall 36, whereby the walls 32, 34, 36 surround a pair of IDC contact portions 18 and extend past upper ends 38 thereof.
  • the compartments 28 also comprise cover retention means in the form of window cutouts 40, and a V-shaped wire receiving slot 42 having a tapered profile 44.
  • the cover member 8 comprising an insulative housing 46, having a wire receiving cavity 48, transversely intersected by IDC contact portion slots 50 extending from a mating face 52, and a single wire seal cylindrical receiving cavity 54 aligned and adjoined to the wire receiving cavity 48 and extending from a wire receiving face 56 of the cover member 8.
  • the cover member 8 also has retention means 58 consisting of tapered projections cooperable with the windows 40 of the base member housing 12.
  • the mating face 52 comprises an outer sealing surface 60 surrounding the IDC receiving slots 50, the contour of the sealing surface 60 being continuous and planar.
  • the branch connector 2 is manufactured by first stamping and forming the branch conductor 10 from sheet metal and then placing it in a mould whereby the insulative housing 12 is overmoulded to the branch conductor 10.
  • the sealing means 14 can then also be overmoulded over the conductor 10 and base 30 of the compartments 28 so as to provide a planar sealing surface on the floor of the compartments 28 that surrounds the IDC contact portions 18 and is biasable against the cover sealing surface 60.
  • the in-moulding of the branch conductor 10 to the housing 12 and sealing floor 14, enables electrical connection between the exterior conducting portion 20 and the IDC portions 18 yet ensuring that the IDC contact portions 18 are completely sealed off from the exterior except for a cover receiving face 62 ( Figure 2) that is then sealed off by the cover member 8 as described hereinafter.
  • the compartment walls 32, 34, 36 extent past ends 38 of the IDC contact portions 18 which provides, among other things, protection thereof against damage during handling and assembly.
  • a single wire seal 64 ( Figure 5) is first inserted into the seal receiving cavity 54 of the cover member 8, the conducting wire 4 is then inserted through a wire receiving cavity 66 of the seal 64 and into the wire receiving cavity 48 until it abuts an end wall 68 of the cover 8.
  • the single wire seal 64 has sealing ribs on its outer and inner surfaces that are resiliently biased against the seal receiving cavity 54 and the wire 4 such that the wire is sealed with respect to the cover member 8 except for the mating face 52.
  • the cover member 8 can than be pressed into the compartments 28 whereby the IDC contacts 24 are inserted into the receiving slots 50 such that the wire 4 is forced into the IDC slots 26 that cut through the insulation and make electrical contact with conducting strands of the wires 4.
  • the exterior portion of the wire 4 adjacent the seal 64 is inserted into the V-shaped slot 42 whereby the wire 4 is squeezed between opposing edges 70, 72 thereof, the tapered profile 44 creating acute angled edges 70, 72 for effectively digging into the wire 4 in order to act as a retention means.
  • the tapered profile 44 is such that the smallest width between edges 70, 72 is adjacent the inner side of the compartment 28 so as to effectively retain the wire from an external pulling force therealong.
  • the sealing surface 60 thereof abuts the sealing floor 14 whereby the cover member 8 can then be further inserted by resiliently biasing the sealing surface 60 thereagainst until the projections 58 of the cover engage in the windows 40 of the compartments 28.
  • the cover member 8 is thus securely latched to the compartments 28 and resiliently biased against the sealing floor 14, the IDC connection between wire 4 and contact portion 18 thus being completely sealed off from the exterior.
  • the sealing means 14 may not be moulded over the whole floor of the compartment but only at a position adjacent the sealing surface 60 of the cover, or the sealing means 14 could be provided as a loose piece or even moulded to the sealing surface 60 of the cover member 8.
  • the connector 2 may also not be a branch connector having a common interconnecting portion 16, but may have separate terminals each having exterior contact portions (20), the exterior contact portions 20 could be of any form known in the prior art.
  • the branch connection is a two position branch connector but of course if need be, a large plurality of IDC contacting portions 18 can be provided by simply extending the interconnecting portion 16 and moulding more compartments thereto. It could even be imagined to provide sealing means along the inner surfaces of the compartment walls 32, 34, 36 surrounding the IDC contact portions 18.
  • the base member 6 of the connector can be assembled to a structure, for example the body work of an automobile, and the conducting wires 4 can be very rapidly and simply electrically connected thereto at a later assembly stage.
  • the provision of a reliable sealed connector without requiring the use of sealing gels or greases whereby insulation displacement technology is used.
  • the wire 4 can be assembled to the cover member 8 and provisionally held thereto during preparation of the harness in an automated process at the harness making location, the seal 64 provisionally holding the wire to the cover member 8.
  • the wire 4 can then be electrically connected to a branch connector, for example, in a very simple manner by merely pushing the cover member 8 into the compartments 28.
  • the cost effective and simple sealed IDC branch connector with stamped and formed terminals 18, 16 that can comprise a large plurality of terminals as desired.
