  • Patent number: 5667408
    Abstract: A smart card connector with a card slot 10 for receiving a smart card employs an end position switch comprising a single resilient contact 14 engaging a stationary post 16 to detect full insertion of a smart card. The resilient contact 14 and the post 16 are mounted in the rear of a housing base 4 which includes resilient data contacts 12 mounted in contact cavities 38 located at the front and rear of the housing base. Contact arms 88 on the data contacts are preloaded so that each contact engages the smart card with a prescribed force and extends into the housing slot for a prescribed distance. The contact arms 88 are located in channels 34 in the housing base and lateral protrusions 36 extending from separator ribs 32 defining the contact channels 34 engage the contacts to preload them.

  • Patent number: 5641314
    Abstract: A PCMCIA receptacle connector 2 for use with a PCMCIA card includes a plurality of receptacle contact terminals 34 positioned in two rows of cavities 18 in a housing 12. Each of the cavities has two cavity sections 20, 28. Mating pin terminal are received through the first cavity section 20 and the contact terminals are inserted from the rear face 16 of the housing 12 into the second housing cavity 28, which has smooth interior walls 32. Each stamped and formed contact terminal 34 has a forward mating section 36, a central contact support section 48, and a rear conductor contact section 42 including surface mount solder tails 44. The contact support section 48 includes resilient spring members 50 in the form of edge stamped cantilever spring members that engage the interior smooth walls 32 of the second cavity section 28 to retain the contacts in the housing 12 and to properly position the mating contact section 36 and the solder tails 44.
