Abstract
A tool battery includes a plurality of battery cells and a holder device. The holder device includes a pair of holder members and a plurality of lead plates mounted to each of the holder members. Each of the holder members has fitting portions for fitting with end portions of the battery cells. The lead plates are electrically connected to the corresponding electrodes of the battery cells.
Claims19
A tool battery comprising:
- a battery housing;
- a plurality of battery cells disposed within the battery housing, each of the battery cells having a first end portion and a second end portion opposite to the first end portion, and each of the first and second end portions including an end surface and an electrode provided at the end surface;
- and
- a holder device configured to hold the first and second end portions of the battery cells in such a manner that the end surfaces of the first end portions of the battery cells are aligned with each other and the end surfaces of the second end portions of the battery cells are aligned with each other, the holder device including:
- a first holder member having a plurality of recesses for fitting with the first end portions of the battery cells;
- a second holder member having a plurality of recesses for fitting with the second end portions of the battery cells;
- a plurality of first lead plates electrically connected to the electrodes provided at the end surfaces of the first end portions of the battery cells, wherein the first lead plates are embedded into the first holder member so as to be exposed at bottoms of the recesses of the first holder member;
- and
- a plurality of second lead plates electrically connected to the electrodes provided at the end surfaces of the second end portions of the battery cells, wherein the second lead plates are embedded into the second holder member so as to be exposed at bottoms of the recesses of the second holder member.
