Definitions

  • the present invention relates to igniter connectors used in automotive air bag equipment.
  • Automotive collision protection systems comprising air bags are known. Is such systems, air bags mounted in a steering wheel and other vehicle locations are instantly inflated by gas produced by a gas generator, which is activated when an impact is detected by a collision detector, thus protecting the driver and passengers of the vehicle.
  • the gas generated by the respective gas generator that is activated by an electric signal applied to an ignition tube from the collision detector, and the collision detector and the ignition tube are connected by means of the ignition connector.
  • Document DE 296 04 891 discloses an electrical connector of the general type used with air bags, which is comprised of an insulting housing and electrical contacts mounted in the housing and a two part cover member on the housing. An intermediate cover member is located between the wire termination portion of the contacts and an outer hinged cover.
  • this connector does not appear to have sufficient room for a ferrite bead surrounding the contacts. Ferrite beads are often used to prevent extraneous signals.
  • US Patent 5,616,045 discloses a squib connector of this type in which a ferrite bead surrounds the wire termination portions of two contacts mounted in a housing and wires extending into the housing. The ferrite bead does not surround the receptacle sections of these contacts.
  • FIG. 10 Another example of such a connector is shown in Figure 10 and is disclosed in Japanese Patent Publication No. 5-105027.

Therefore, after the insulating housing 210 is closed by the cover member 250, the movement of the electrical contacts 241, 242 is limited by the projections 262 even if the electrical wires are pulled, thereby preventing structurally weak guiding sections 245 of the electrical contacts 241 from breaking or becoming misaligned.

  • a partition is located in the bead-receiving cavity insulating the contact sections from each other.
  • the cover member has pressure members intended to press the ferrite bead against the bottom of the bead-receiving cavity. Therefore, when the cover member is secured on the insulating housing, the ferrite bead becomes positively retained in the bead-receiving cavity.
  • the posts When the cover member is placed on the housing, the posts are engaged with guiding sections of the electrical contacts, thus aligning the contact sections of the electrical contacts with the pin-insertion holes. Therefore, the igniter pin terminals passing through the pin-insertion holes form precise pin-and-socket connection with the contact sections of the electrical contacts.
  • Lugs are provided on the side walls of the bead-receiving cavity that, by engaging with outer walls of the ferrite bead, positively prevent it from being rocked inside the cavity. This makes it possible to compensate for small variations in the external dimensions of the ferrite bead appearing in the process of sintering thereof.
  • Lugs are provided between the guiding sections and the wire-connecting sections of the electrical contacts which, together with projections provided on the cover member limit the movement of the electrical contacts if the electrical wires connected to the contacts are pulled. Therefore, when the insulating housing is closed by the cover, the lugs prevent the structurally weak guiding sections from damage caused by pulling forces on the electrical wires by limiting the movement of the electrical contacts.
