ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to electronic module guide frames and more particularly to guide frames having light transmission members thereon.
BACKGROUND OF THE INVENTION
Light transmission members are known to be used in conjunction with electrical connectors as disclosed in U.S. Pat. No. 5,876,239 wherein the light transmission members extend along housing members of the electrical connectors with inner ends of the light transmission members being disposed adjacent light emitting diodes or devices (LEDs) mounted on a circuit board onto which the electrical connectors are to be mounted while outer ends of the light transmission members are located at a front end of the housing members to display light emanating from the LEDs via the light transmission members.
The construction of the light transmission members and the housing members to which they are mounted is complex. Moreover, assembly of the light transmission members to the housing members is difficult and time consuming. Thus, the complex structure and the difficulty of assembly increase the cost of manufacture of the connectors.
SUMMARY OF THE INVENTION
An important feature of the present invention is to provide light transmission members on an electronic module guide frame that transmit light to a front end of the guide frame from LEDs on a circuit board to indicate the operation of an electronic module, such as a Gigabit Interface Converter (GBIC) module, within the guide frame.
A guide frame according to the present invention comprises side walls, a rear wall and a front section defining an entrance through which an electronic module is inserted for disposition within the frame, a light transmission mounting area on one of the side walls, light transmission members disposed on the light transmission mounting area, and mounting members provided by the light transmission mounting area and the light transmission members mounting the light transmission members on the light transmission mounting area.
The light transmission mounting area includes a light-blocking member along which the light transmission members extend.
The light transmission mounting area is a simple addition to an existing guide frame and the light transmission members can easily be mounted onto the light transmission mounting area.
