Electronic subassembly for a personal care product
An electronic subassembly for a personal care product with a housing defining a chamber. The housing has a tapered guide surface. A first circuit board having a rigid end is positioned within the chamber and a flexible portion positioned outside the chamber. A second circuit board is positioned within the chamber of the housing. The second circuit board has an electrical connector dimensioned to receive the rigid end. An adapter is secured to the first circuit board between the rigid end and the flexible portion. The adapter has a corresponding tapered guide surface that engages the tapered guide surface of the housing to align the rigid end with the electrical connector.
1. An electronic subassembly for a personal care product comprising:
a housing defining a chamber, the housing defining a tapered guide surface;
a first circuit board having a rigid end positioned within the chamber and a flexible portion positioned outside the chamber;
a second circuit board positioned within the chamber of the housing, the second circuit board having an electrical connector dimensioned to receive the rigid end; wherein the tapered guide surface aligns the rigid end with the electrical connector and a sealant filled around the first circuit board preventing water ingress to the rigid end.
2. The electronic subassembly of claim 1 wherein the housing defines a slot in communication with an opening and the electrical connector is in close proximity with the slot.
3. The electronic subassembly of claim 1 wherein the flexible portion is coupled to a heating element.
4. The electronic subassembly of claim 1 wherein the second circuit board is supported by a chassis.
5. The electronic subassembly of claim 4 wherein the chassis has a first end having a platform and a battery housing.
6. The electronic subassembly of claim 5 wherein the second circuit board is mounted on the platform.
7. The electronic subassembly of claim 6 wherein the platform is flat.
8. The electronic subassembly of claim 4 wherein the chassis has a guide member that engages a corresponding guide member on an inner surface of the housing.
9. An electronic subassembly for a personal care product comprising:
a housing defining a chamber and an opening at a first end of housing in communication with the chamber, the housing defining a tapered guide surface;
a first circuit board having a rigid end positioned within the chamber and a flexible portion positioned outside the chamber;
a second circuit board positioned within the chamber of the housing, the second circuit board having an electrical connector dimensioned to receive the rigid end; wherein the electrical connector is in close proximity to a slot in communication with the opening.
10. The electronic subassembly of claim 9 wherein the housing comprises a tapered guide surface aligning the rigid end with the electrical connector.
11. The electronic subassembly of claim 10 further comprising a sealant filled around the first circuit board preventing water ingress to the rigid end.
12. The electronic subassembly of claim 9 wherein the flexible portion is coupled to a heating element.
13. The electronic subassembly of claim 9 wherein the second circuit board is supported by a chassis.
14. The electronic subassembly of claim 13 wherein the chassis has a first end having a platform and a battery housing.
15. The electronic subassembly of claim 14 wherein the second circuit board is mounted on the platform.
16. The electronic subassembly of claim 15 wherein the platform is flat.
17. The electronic subassembly of claim 15 wherein the chassis has a guide member that engages a corresponding guide member on an inner surface of the housing.
18. An electronic subassembly for a personal care product comprising:
a housing defining a chamber in communication with an opening at a first end of the housing;
a first circuit board having a rigid end positioned within the chamber and a flexible portion positioned outside the chamber;
a sealant filled around the first circuit board preventing water ingress to the rigid end;
a second circuit board positioned within the chamber of the housing, the second circuit board having an electrical connector dimensioned to receive the rigid end and in close proximity to a slot in communication with the opening, wherein the housing has a tapered guide surface aligning the rigid end with the electrical connector.
19. The electronic subassembly of claim 18 wherein the flexible portion is coupled to a heating element.
20. The electronic subassembly of claim 18 wherein the second circuit board is supported by a chassis having a first end with a platform and second end having a battery housing.
