Abstract: A T-shaped groove is cut out from a section of a guide wall of a memory card connector. The groove also defines an interior T-shaped portion. The bar portion of the interior T-shaped portion is bent back 180 degrees so that it extends over the groove from which it was cut out. The bar portion of the interior T-shaped portion makes contact with the edges of the groove preventing the interior T-shaped portion from moving through the groove. The interior T-shaped portion also has an arcuate portion that resiliently holds a memory card in place. The memory card connector also includes a connection part and at least one other guide wall arraigned to from a U-shaped slot for holding a memory card.

Abstract: An extender card is formed from first and second plastic clamshell halves which are intermated with one another and ultrasonically welded together. The first clamshell half is sized to be received within an outer periphery of the second clamshell so that, once welded, the resulting extender card housing body is strong and attractive in that the weld is internal and hidden from view. A cable tie is secured to a cable extending from the extender card and received within a collar of the extender card housing body to provide strain relief for the cable. One or more apertures are formed through the extender card housing body to allow access to a PCMCIA card or PC card installed adjacent to the extender card, for example, to a modular jack receiving structure of a PC modem or network card.
