Abstract

This is a system and method by which the light from a light source on a selectively attached portable expansion device, such as a PCMCIA card, is more visible to a user. It is accomplished by using a light transfer medium, such as transparent plastic, in the plug of a media cable. The light transfer medium is molded in such a way to continue the path of light from the connector interface into the plug of the media cable. Inside the plug the light reflects off of a molded reflector in an upward and outward direction. The light can then be viewed through a transparent opening or viewing window, which may be bubbled or rounded to increase the overall viewing angle. Thus, it is an overall object of the present invention to provide an electrical connector that has a low physical profile but a high optical profile and is particularly useful in devices and peripherals implemented in reduced-size form factors, such as PC cards, compact flash cards or other removable media.

Claims

1. A connector system for coupling a cable to a host device, the connector system comprising:

a light source disposed within the host device, the light source being capable of emitting a light signal;

an electrical connector having a socket, the electrical connector further including a light conducting portion that is optically coupled to the light source and that is capable of conducting at least a portion of the emitted light signal to a light emitting surface disposed along the majority of an outer periphery of the socket; and

a plug having a body disposed on an end of the cable, at least a portion of the plug capable of being operably received within the socket so as to provide an electrical connection between the cable and the host device, wherein the plug further comprises;

an optical conducting portion defining a light conducting path within the plug body, the optical conducting portion being optically coupled with the light emitting surface when the plug is operably received within the socket so as to conduct the light signal emitted therefrom;

at least one viewing portion positioned on the plug so as to emit at least some of the light signal received by the optical conducting portion for visual inspection; and

at least one reflector, positioned so as to reflect at least some of the light signal present within the optical conducting portion substantially towards the at least one viewing portion.

2. The connector system of claim 1, further comprising at least one optical dispersion member disposed at a point along the light conducting path.

3. The connector system of claim 2, wherein the optical dispersion member is a prism.

4. The connector system of claim 1, wherein the at least one viewing portion is substantially planar with an outer surface of the plug.

5. The connector system of claim 1, wherein the at least one viewing portion includes a rounded surface.

6. The connector system of claim 1, wherein the emitted light signal indicates an operations status of the host device.

7. The connector system of claim 1, wherein the host device is a device conforming with the physical and electrical requirements of the PCMCIA standard.
