Abstract
A device wherein optoelectronic componentry and circuitry is carried on a single component board (70) mounted in a one-piece case (1) having a main section (10) with a compartment (20) therein for accommodating and holding the board and having at the back thereof a hinged flap (16) defining an opening for inserting the board into the compartment and adapted to lock the board in place when closed, and opposite from the flap, a front end terminal part (50) bounding the front of the compartment and provided with passages therethrough issuing into the compartment for insertion of optical fibers (6, 7) and a clamp (68, 8) for holding the fibers. The device is particularly applicable to equip automatic mail sorting machines.
Claims10
An optoelectronic device for detecting at a distance the passage of objects comprising:
- a component board carrying on a single surface of said board optoelectronic components consisting of a light source and a photodetector arranged substantially side by side at a first end of said board and associated components mounted in hybrid circuits on said surface of said board, a unitary molded plastic case having a main section including an open bottom compartment for receiving said board, and a front end terminal part which extends to one side of said main section, said case compartment being limited by a top wall and laterally by said front end terminal part, an opposite rear wall, and two side walls, said case having means for holding said component board in position such that such compartment is substantially closed by said component board and being provided with a substantially centered partition extending from the front end terminal part into said open bottom compartment and defining two subcompartments for receiving the light source and the photodetector, respectively, said front end terminal part being provided with two holes opening into said two subcompartments respectively on an external opposed face, and two optical fibers mounted and clamped within said two holes respectively, in axially alignment with said light source and said photodetector said rear wall being a continuation of said molded plastic case top wall and including a transverse groove molded therein to define a rear wall hinged flap pivotable about said groove.
An optoelectronic device for detecting at a distance the passage of objects comprising:
- a component board having opposite faces and a first and second end, and carrying on one face of said board optoelectronic equipment consisting of a light source and a photodetector arranged substantially side by side at said first end and having associated components mounted in hybrid circuits on said one face of said board, a unitary body having a main section part defining an open bottom compartment for receiving said component board with said optoelectronic equipment and a front end terminal part which extends on one side of said main section part and in which body:
- said compartment is delimited by a top wall, and laterally by said front end terminal part, an opposite rear wall, and two side walls and extending between said front end terminal part and said opposite rear wall at opposite ends thereof and providing an open bottom, said body being provided with a substantially centered partition extending from the front end terminal part into said compartment and defining two subcompartments for housing the light source and photodetector, respectively, said front end terminal part being provided with two holes opening into said two subcompartments, respectively, and having mounted on an external, opposed face thereof, two optical fibers, said two optical fibers being clamped within said two holes, respectively, in axial alignment with said light source and said photodetector.
