Contact pin design for a modular jack
First Claim
1. A jack for connecting a RJ series plug to a communications card conforming to Type III PCMCIA standards, the jack comprising:
- a housing including an upper surface, a lower surface and a front wall, the upper surface and the lower surface of the housing being separated by a distance equal to or less than about 10.5 mm;
a receptacle located in the front wall of the housing, the receptacle including an upper surface and a lower surface that are separated by a distance equal to or less than about 10.1 mm, the receptacle being sized and configured to receive a RJ series plug such that no portion of the plug extends through either the upper surface or the lower surface of the housing; and
a plurality of contact pins located in the housing, the contact pins being sized and configured to allow electrical communication between a connector plug inserted into the receptacle and the communications card, the contact pins including a plug engaging portion that is sized and configured to electrically communicate with the RJ series plug received within the receptacle and a connector portion that is sized and configured to electrically connect the contact pin to a communication card.

Abstract
A communications card allows computers to be electrically connected to electronic devices and communications systems. The communications card includes a modular jack with a plurality of contact pins. The contact pins include a plug engaging portion that does not include any sections that are angled more than about 90° in order to minimize the stresses in the contact pins. The contact pins also include a connector portion that allows the contact pins to be electrically connected to a printed circuit board disposed within the communications card. Preferably, the plug engaging portion includes an elongated arm that aids in absorbing stress and deflection of the contact pins. Advantageously, the contact pins are designed to minimize the height of the modular jack such that the modular jack can be used with communications cards that comply with the PCMCIA Type III standards.
