Abstract

The modular jack allows a RJ series connector plug to be attached to a communications card that conforms to the PCMCIA requirements for a Type III card. The modular jack includes a main body portion including a top surface, a bottom outer surface and a front surface. The receptacle is disposed entirely within the front surface of the modular jack such that no portion of the plug extends through either the top surface or the bottom surface of the main body portion of the modular jack. Thus, the modular jack allows the communications card to be connected to standard RJ series plugs without deviating from the Type III PCMCIA card height requirement, even when the plug is inserted into the jack. Desirably, the main body portion has a height measured from the top surface to the bottom surface that is generally equal to or less than about 10.5 mm. Additionally, the receptacle preferably includes an upper inner surface and a lower inner surface that are separated by a distance that is generally equal to or less than about 10.1 mm. The modular jack may also include a latching area that securely holds the connector plug within the receptacle, but allows the connector plug to be removed from the receptacle without the user depressing a biased clip of the connector plug if a predetermined force is applied to a body of the connector plug.
