Abstract
In a case where an electrode-equipped button battery and a button battery socket are mutually exclusively mounted on a printed circuit board, a pattern prohibition region of one component is not overlapped with a mounting pattern of the other component, and outer shape regions of the two components are at least partially overlapped with each other on the printed circuit board.
Claims19
A printed circuit board on which a first button battery or a socket for a second button battery is capable of being mounted, the first button battery including a first electrode, and defining a first pattern prohibition region, and a first outer shape region, the socket including a second electrode, and defining a second pattern prohibition region, and a second outer shape region, the printed circuit board comprising:
- a first mounting land configured to mount the first electrode;
- and
- a second mounting land configured to mount the second electrode;
- wherein the first mounting land is disposed in a region of the printed circuit board different from the second pattern prohibition region, and the second mounting land is disposed in a region of the printed circuit board different from the first pattern prohibition region, and
- wherein the first mounting land and the second mounting land are disposed on the printed circuit board in such a manner that the first outer shape region and the second outer shape region are at least partially overlapped on the printed circuit board.
A system comprising a first printed circuit board on which a first button battery is capable of being mounted, and a second printed circuit board on which a socket for a second button battery is capable of being mounted, the first printed circuit board being connectable to the second printed circuit board, the first button battery including a first electrode, and defining a first pattern prohibition region and a first outer shape region, the socket including a second electrode, and defining a second pattern prohibition region and a second outer shape region, the first printed circuit board comprising:
- a first mounting land configured to mount the first electrode;
- and the second printed circuit board comprising:
- a second mounting land configured to mount the second electrode;
- wherein, with the first printed circuit board connected to the second printed circuit board:
- the first mounting land is disposed in a region of the first printed circuit board different from the second pattern prohibition region, and the second mounting land is disposed in a region of the second printed circuit board different from the first pattern prohibition region, and
- the first mounting land and the second mounting land are disposed on the first and second printed circuit boards in such a manner that the first outer shape region and the second outer shape region are at least partially overlapped on the first and second printed circuit boards.
