Sandwich housing for an antenna amplifier
An antenna amplifier has its printed circuit board clamped between upper and lower housing parts which have peripheral edges raised to engage the periphery of the circuit board between them. A recess in the housing part can clear a plug connector on the circuit board. Resilient catches can connect the housing parts to apply pressure on the circuit board.
1. A housing for an electronic device, the housing comprising:
a first housing bottom part having an edge and an upstanding rim;
a second housing top part having an edge and a downwardly extending rim, one of the rims being formed with an opening;
detents spaced around and projecting past the rim of one of said housing parts;
respective resilient catches spaced around the rim of the other of the housing part, engaging the detents with prestress, and pressing said housing parts together to define a housing interior; and
a circuit board having an outer edge engaging the rim of the one housing part, the detents engaging the outer edge, centering, surrounding, and not engaging through the circuit board, the circuit board being clamped between the rims of said housing parts and secured thereby in said housing, said circuit board having circuit elements received in said housing interior and a connector fitting into and exposed at the opening of the one rim.
2. The housing defined in claim 1 wherein said circuit board is an antenna amplifier circuit board.
3. The housing defined in claim 1 wherein the connector is a plug connector on said board.
4. The housing defined in claim 1 wherein the circuit board is secured in said housing exclusively by a connection of said housing parts together.
5. The housing defined in claim 1 wherein said housing parts are interconnected by a hinge.
6. The housing defined in claim 5 wherein said hinge is a film hinge.
7. The housing defined in claim 1 wherein said housing parts are secured together by a coined element, an ultrasonic weld, a threaded element, a rivet, or an adhesive bond.
8. The housing defined in claim 1 wherein one of said housing parts has a pair of pins extending through holes in said board.
9. The housing defined in claim 1 wherein said housing parts have a hole for a screw for mounting said housing on a part of an automobile body.
10. The housing defined in claim 1 wherein the rims interfit and overlap, whereby the entire circuit board except the connector are wholly contained within the housing.
11. The housing defined in claim 1 wherein the detents and catches are unitarily formed with the respective housing parts.
