SELF-SEALING ACCESS PORT FOR SMART CARD OR SIMILAR DEVICE

by Henry Wandt, Donald J. Szczepanik and John B. Miles

  Many different categories of electronic products are or will be utilizing card format devices for appli- cation such as user identification, data storage, and financial transactions. A typical example is the cur- rent application of a smart card to store user infor- mation in a cellular telephone.

  A key advantage in utilizing card devices to accomplish these functions is their ease of use. The cards are light, compact, and robust allowing conve- nient storage and carry of extra cards. In addition, the devices which incorporate these cards typically are designed to allow the user to insert or extract a card without any disassembly of the device. This ease of access presents a challenge to the product designer concerned with sealing the card access port against the intrusion of foreign material, water, and electrostatic discharge. Most designers chose to ignore sealing the port rather than add a discrete seal which would increase the cost and probably the size of the product.

  The self-sealing access port illustrated on next page, solves the sealing problem without adding any additional parts to the product by incorporating the sealing features into an existing part, namely, the "snubber." The snubber is an injection molded elas- tomeric part which is used to isolate fragile compo- nents from the shock loads generated when...
