Abstract

Claims (35)

1 . A printed circuit board (PCB) housing comprising:

a main body including an opening with an uppermost edge surface and an internal PCB receiver portion for locating and accommodating a PCB within the main body; and

a cover for interfacing with an outer edge surface of the opening and enclosing the PCB within the main body, wherein:

the cover includes a PCB retainer configured to contact against a surface of the PCB such that, when assembled, the PCB is retained securely in position between the PCB receiver portion and the PCB retainer,

the cover includes an outwardly extending resilient flange or bridge configured to cover the opening of the main body to press against and be welded to the uppermost edge surface under tension,

the uppermost edge surface of the opening includes a chamfer configured to optimize a contact area with the flange or the bridge, and

chamfer angles are positioned in an outward direction from the opening to accommodate the flange or the bridge bending toward the edge surface.

2 . The PCB housing of claim 1 wherein the flange or the bridge includes a rib extending upwardly from the cover, away from the main body, for facilitating positioning of a pressing tool.

3 . The PCB housing of claim 2 wherein the rib extends about a substantive perimeter of the flange or the bridge.

4 . The PCB housing of claim 1 wherein the PCB receiver portion and the PCB retainer are configured to engage the PCB simultaneously and at least one peripherally located contact portion of upper and lower surfaces thereof.

5 . The PCB housing of claim 4 wherein the PCB receiver portion and/or the PCB retainer includes at least one L-shaped element.

6 . The PCB housing of claim 5 wherein the at least one L-shaped element includes four L-shaped elements corresponding to corner located contact portions of the upper and lower surfaces of the PCB.

7 . The PCB housing of claim 1 wherein the flange or the bridge and the uppermost edge surface of the opening are located externally to and laterally spaced apart from the PCB receiver and the PCB retainer such that forces required to fix the cover to the body are directed at locations offset from the PCB.

8 . The PCB housing of claim 1 wherein:

the PCB housing is a camera unit;

the PCB includes an imager; and

the main body is coupled with a lens barrel at an end opposite the cover and the opening.

9 . A method of assembling a printed circuit board (PCB) housing, the method comprising:

locating a PCB onto a PCB receiver of a main body of the PCB housing such that the PCB receiver is in contact with a contact portion of a lower surface of the PCB;

aligning a cover of the PCB housing over a chamfered uppermost edge surface of an opening of the main body, thereby inserting a PCB retainer of the cover into the opening to achieve a pre-fixing position, wherein:

the PCB retainer is arranged in contact with an opposing contact portion of an upper surface of the PCB,

a gap is present between a bridge of the cover and the uppermost edge surface of the opening, and

the chamfer of the chamfered uppermost edge surface is angled in an outward direction from the opening; and

applying a vertical pressing force to a flange of the cover or the bridge to cause deformation thereof and to move the flange or the bridge into contact with the uppermost edge surface of the opening of the main body to achieve a fixing position.

10 . The method of claim 9 further comprising:

welding the bridge to the edge surface.

11 . A printed circuit board (PCB) housing comprising:

a main body including an opening with an uppermost edge surface and an internal PCB receiver portion for locating and accommodating a PCB within the main body; and

a cover for interfacing with an outer edge surface of the opening and enclosing the PCB within the main body, wherein:

the cover includes a PCB retainer configured to contact against a surface of the PCB such that, when assembled, the PCB is retained securely in position between the PCB receiver portion and the PCB retainer,

the cover includes an outwardly extending resilient flange or bridge configured to cover the opening of the main body to press against and be welded to the uppermost edge surface under tension,

the uppermost edge surface of the opening includes a chamfer configured to optimize a contact area with the flange or the bridge,

chamfer angles are positioned in an outward direction from the opening to accommodate the flange or the bridge bending toward the edge surface, and

the flange or the bridge includes a rib extending upwardly from the cover, away from the main body, for facilitating positioning of a pressing tool.

12 . The PCB housing of claim 11 wherein the rib extends about a substantive perimeter of the flange or the bridge.
