• the side wall 46 includes an inner side wall surface 52, which will be discussed in greater detail subsequently.
• Two guides 53, 55 are used to guide the peripheral adapter 44 into the receptacle 42.
• the guides 53, 55 may be simple side walls, as shown in the Figures, or they may include grooves.
• connection assembly 20 also includes an electrical contact 54.
• the electrical contact 54 extends along at least one interior wail 56 of the receptacle 42.

• the electrical contact may include a plurality or set of contacts 54, 54', 54" (shown in Figure 1), so that multiple functions may be performed through the single "point" of contact.
• 3 54 is a single contact, it may merely provide a voltage at that point. If the electrical contact is actually a set of contacts 54, 54', 54", each may supply a voltage, a data signal, and audio/video signal, respectively. Depending on the protocol and data compression used, one or more types of data may be transmitted through a single contact. Additional electrical contacts may be incorporated into the guides 53, 55, depending on the data capacity requirements.
