Method for an integrated I/O connection socket

Disclosed is a method for an integrated input/output (I/O) connection socket. Benefits include improved design flexibility, improved test and inspection, and improved manufacturability.

Background

      Conventionally, different types of connectors, such as RJ45, USB, and 1394, must have sockets that are for specific to the connector type. This situation limits board flexibility. This problem is conventionally solved by utilizing separate footprints for the various connectors, requiring the feature set to be specified at the time of printed circuit board (PCB) layout.

      Integrated RJ45 connectors require a relatively low reflow oven temperature, which restricts lead-free surface mount technology (SMT) processing. Lead free products are conventionally not in production, and the problem is not being addressed. However, government legislation in the U.S., Europe, and Japan is expected to ban lead in computer products, forcing changes to components and processing.

      Integrated RJ45 connectors have too many pins to bring them all out the back of the connector. A surface-mounted version of an integrated RJ45 would require some of the pins to be obscured from view by the body of the connector. Surface-mount integrated RJ45 connectors are rare and only exist in single port versions.

      Multiple types of connectors require multiple board SKUs and specific LED indicator colors. These restrictions are viewed unfavorably by equipment manufacturers (OEMs). Conventionally, each type of connector has a separate board SKU and different LED colors. Multiple connectors are not implemented as the feature set is specified at the time of board layout.

              Conventional solutions are typically not reflow compatible, only available in through-hole mount, and are affixed to the board during soldering (see Figure 1). LED colors cannot be adjusted after the component has been manufactured.

General description

      The disclosed method is a separate connector for facilitating processing and enabling flexibility on boards requiring integrated local area network (LAN) or integrated LAN-combination connectors.

      The key elements of the method include:

·        A low-profile socket is mounted on the PCB either by through-hole mount technology or SMT.

·        The socket accepts either an integrated RJ45 over 2 USB, or an integrated RJ45 over 2 1394, or a single...
