Method of assembling an electronic subassembly for a personal care product
A method of assembling an electronic subassembly for a personal care product by manufacturing a hollow housing defining a chamber having a first open end and an opposing second open end. A rigid end of a first circuit board is inserted into the first open end of the housing. A second circuit board subassembly having a second circuit board is inserted into the chamber through the second open end. The first circuit board is connected to the second circuit board within the chamber of the housing.
1. A method of assembling an electronic subassembly for a powered personal care product comprising:
manufacturing a hollow housing defining a chamber having a first open end and an opposing second open end;
inserting a rigid end of a first circuit board into the first open end of the housing;
inserting a second circuit board subassembly having a second circuit board into the chamber through the second open end; and
connecting the first circuit board to the second circuit board within the chamber of the housing,
further comprising assembling a first circuit board subassembly by connecting the first circuit board to the housing, wherein said connecting the first circuit board to the housing comprises molding plastic around a portion of the rigid end of the first circuit board to form a seal between the rigid end and the housing,
wherein the first circuit board is molded to the housing prior to inserting the second circuit board subassembly into the chamber through the second open end, and
further comprising sealing the opposing second open end.
2. The method of claim 1 further comprising suspending a portion of the rigid end within the chamber.
3. The method of claim 1 further comprising positioning a flexible portion of the first circuit board outside of the housing.
4. The method of claim 1 wherein said sealing comprises mounting an end cap to the housing.
5. The method of claim 1 wherein said connecting the first circuit board to the second circuit board comprises inserting a rigid end of the first circuit board into a connector of the second circuit board.
6. The method of claim 1 further comprising assembling the second circuit board subassembly by mounting the second circuit board to a platform of a chassis.
7. The method of claim 6 further comprising mounting a battery to the chassis.
8. The method of claim 7 wherein the battery is mounted to the chassis prior to inserting the second circuit board subassembly into the housing.
9. The method of claim 1 further comprising aligning a connector on the second circuit board with the rigid end of the first circuit board.
10. The method of claim 9 wherein said aligning comprises engaging the second circuit board subassembly with a plurality of ribs of the housing.
11. The method of claim 1 further comprising connecting a flexible portion of the first circuit board subassembly to a heating element on a shaving razor cartridge.
