Definitions

  • This invention is directed to an electrical harness and connector incorporating a suppression device to prevent spurious signals from passing therethrough and is particularly suited, although not limited to, forming an interconnection in an automobile airbag system.
  • Automobile airbags are inflated by an initiator having a squib that is electrically triggered by currents originating from a control system.
  • the control system is connected to the initiator by a wiring harness which is typically provided with an electrical connector to permit easy interconnection of the initiator and the control system after they have been separately installed.
  • One common design involves having the initiator mounted upon the airbag assembly where male terminals, such as tabs or pins, extend therefrom for engagement by receptacle terminals of the electrical connector. This enables a simple plug-in assembly to be utilized.
  • U.K. Patent Application GB 2 267 188 A discloses an electrical connector for connecting conductors of a flat cable of a wiring harness to the terminals of the initiator.
  • the connector terminals are soldered to their respective cable strips and extend orthogonally therefrom.
  • the electrical component or choke is interconnected at one end to one of the conductive strips and at the other to an extension of that conductive strip which is electrically isolated therefrom by an opening thereacross. This extension is then interconnected with one of the interconnection terminals, thereby incorporating the suppression device into the conductive path.
  • the electrical component or suppression device may be similarly soldered to the conductive strip as done with the connector terminals. All of this is incorporated within a two-part connector housing snapped together and including inter-engaging spikes/cavities that pierce the cable insulation for fixing the flat conductor cable to the pin and contact connector.
  • an insulating housing includes a plurality of electrical terminals having wire terminating sections for engaging insulated wire conductors. These terminating sections are formed at a right angle with mating sections that electrically engage the initiator contacts. Disposed between the wire terminating sections and the mating section is a lead receiving slot for engaging a lead of the suppression device without the need for soldering. All of which is enclosed within an insulative housing having a latchable cover with retention arms for maintaining the suppression device in place.

Physical engagement of the cable may be enhanced by providing openings or surface regularities along the insulation wherein the melt that forms the strain relief tail 14 may flow for engagement therewith. Other strain relief tail configurations may also be advantageously used.
  • an electrical connector is provided that is especially advantageous for use with automated assembly, as all assembly motion is directed along a common axis.
  • the interconnections are formed without the use of solder and the associated heat and chemical by-products.
  • overmoulding a strain relief boot about the cover and the housing the components contained therein are prevented from becoming dislodged as the cover is positively retained.
  • unitarily moulding a strain relief tail with the strain relief boot external forces exerted upon the insulated cable are transferred directly into the housing and the cover as opposed to disrupting the interconnection with the conductors of the cable.
