Wiring module
In a battery wiring module that is to be attached from a Y-axis direction (second direction) to a single battery group in which multiple single batteries that have electrode terminals are aligned in the X-axis direction (first direction), multiple holding units that are coupled in the X-axis direction and constitute a holding plate are each provided with a locking hook including a first locking surface and a second locking surface, and a locked hook that includes a first locked surface and a second locked surface, and by relatively sliding the holding units in the X-axis direction, the holding units can be coupled in a first locking state in which the first locked surface is locked to the second locking surface, or in a second locking state in which the first locked surface is locked to the first locking surface of the locking hook and the second locked surface is locked to the second locking surface.
1. A wiring module to be attached to a power storage element group in which a plurality of power storage elements having positive and negative electrode terminals are aligned in a first direction, the wiring module configured to be attached from a second direction orthogonal to the first direction, comprising:
connection members to be connected to the electrode terminals; and
a plurality of holding units that are coupled in the first direction and hold the connection members,
wherein the holding units are each provided with:
a locking portion that locks and couples a holding unit adjacent to the holding unit, and
a locked portion that is locked to the locking portion of a holding unit adjacent to the holding unit, and
a plurality of at least one of the locking portions and the locked portions are provided in alignment in the first direction in the holding unit and are configured such that an interval between the adjacent holding units can be changed in a stepwise manner, wherein the locking portion of the holding unit is configured to lock with the locked portion of an adjacent holding unit at a first set interval of a plurality of set intervals so that a distance taken in the first direction between the holding unit and the adjacent holding unit is kept constant and maintained at a predetermined length that corresponds to the first set interval.
2. The wiring module according to claim 1 , wherein the locked portions of the holding units can each be locked to the locking portion of a holding unit adjacent to the holding unit by sliding along the first direction.
3. The wiring module according to claim 1 , wherein the locked portions of the holding units can each be locked to the locking portion of a holding unit adjacent to the holding unit by being pressed along the second direction.
4. The wiring module according to claim 1 , wherein the interval between the adjacent holding units is configured to be changeable in a stepwise manner by changing at least one of the locking portion and the locked portion used to couple the adjacent holding units.
5. The wiring module according to claim 4 , wherein the locked portions of the holding units can each be locked to the locking portion of a holding unit adjacent to the holding unit by sliding along the first direction.
6. The wiring module according to claim 4 , wherein the locked portions of the holding units can each be locked to the locking portion of a holding unit adjacent to the holding unit by being pressed along the second direction.
