ABSTRACT:

BACKGROUND
The present invention relates to a mounting bracket. More particularly, the present invention relates to a bracket for mounting an optical component relative to a circuit board.
Due to their ability to transmit large amounts of data, optical fibers are being used more frequently for data and optical transmission. The optical fibers are generally coupled with data processing circuitry, such that data or optical signals can be transferred between the optical fiber and the circuitry. In many applications, the circuitry may be provided on a daughter circuit board which is mounted vertically on a mother circuit board. As such, there is a need to mount the optical equipment, for example a photodiode or laser, relative to the circuitry on the daughter board. Due to the fine size of the fiber optics, it is necessary to mount the optic components with precision.
A prior art mounting arrangement is shown in
FIG. 1. A
daughter circuit board
12
is vertically mounted relative to a mother circuit board
10
. A mounting bracket
14
is secured to the mother board
10
via screws
16
or the like. The mounting bracket
14
can be made precisely such that the fiber optic path
22
is in precise alignment with the circuitry target
24
. However, if the daughter circuit board
12
moves relative to the mother board
10
, for example during shipping or installation, the alignment between the optic path
22
and the circuit target
24
may be negatively effected.
Accordingly, there is a need for a mounting bracket which allows the optical component to be mounted relative to the daughter board while maintaining the alignment of the components and within the parameters of optical equipment.
SUMMARY
The present invention relates to a bracket for mounting an optical component to a circuit board. The bracket comprises a bracket body member having a board contacting side and a component receiving side. A board contacting surface extending in a first plane is defined along the board contacting side. A component mount is defined along the body member with a termination surface extending adjacent the board contacting side in a plane recessed from the first plane.
