A contacting module for optical and electronic interfaces
A recently filed patent (Publication Number: US20230296668A1) describes a contacting module that includes an optical module and an electronic module. The optical module consists of an optical block made of glass with an arrangement of optical interfaces in an optical interface plane. The electronic module contains a carrier plate, a printed circuit board, and a needle carrier with an arrangement of contacting needles and needle tips, forming electrical interfaces in an electrical interface plane. The optical module and electronic module are positioned relative to each other to have a defined adjustment position in all six degrees of freedom of a Cartesian coordinate system.
In one embodiment, the optical block is permanently connected to the carrier plate using at least three cylindrical pins. The pins contact the optical block via adhesive, and the carrier plate has parallel through holes where the pins are connected to the plate using adhesive. Another embodiment involves a mounting plate that is connected to the carrier plate via a detachable connection, allowing for repeated production of the adjustment position between the optical and electrical interfaces.
The patent also describes methods for assembling the contacting module with the optical module. One method involves adjusting the optical interfaces to the electrical interfaces and then permanently connecting the optical block to the carrier plate using an adhesive connection. Another method includes connecting a mounting plate to the carrier plate in a relative position that can be repeatedly established, adjusting the optical interfaces to the electrical interfaces, and then permanently connecting the optical block to the carrier plate using an adhesive connection. In both methods, at least three cylindrical pins are guided through parallel through holes in the carrier plate or mounting plate, with adhesive applied to the first end face of the pins that faces the optical block.
Overall, this patent presents a contacting module that allows for precise alignment and connection between optical and electrical interfaces. The use of cylindrical pins and adhesive connections ensures a secure and stable arrangement, while the detachable connection in the mounting plate allows for repeated adjustment and production of the desired alignment. These innovations have the potential to improve the performance and reliability of contacting modules in various applications.
