The effect of present embodiment, effect

Then, the effect of present embodiment, effect are illustrated.Present embodiment is interconnection module 10, is disposed in electric power storage Element group 12, charge storage element group 12 are arranged by multiple charge storage elements 11 with electrode terminal 14 along parallel direction, cloth Wire module 10 has: the 1st cell columns 30, passes through the sliding connection of the 1st flexion bond 35 and the 1st by multiple 1st units 33 Portion 36 links, and the 1st unit 33 stores the 1st bus 37 of at least one connecting with electrode terminal 14, the 1st flexion bond 35 With the deflection division 39 that can adjust the mutual interval of multiple Unit the 1st 33, the 1st sliding linking part 36 has inner wall 40A, outer wall 41A；2nd cell columns 31 are linked by multiple 2nd units 51 by the 2nd linking part 52, the storage of the 2nd unit 51 and electrode The 2nd bus 54 of at least one that terminal 14 connects, and the 2nd unit 51 is arranged with the 1st cell columns 30, the 2nd linking part 52 tool There are the inner wall 40B that can adjust the mutual interval of multiple Unit the 2nd 51, outer wall 41B；And column linking part 32, it is connected to the 1st The both sides of cell columns 30 and the 2nd cell columns 31 and the 1st cell columns 30 and the 2nd cell columns 31 are linked, and have can Adjust the column variable spaced portion 57 at the interval between the 1st cell columns 30 and the 2nd cell columns 31.

According to above-mentioned composition, can by deflection division 39, inner wall 40A, outer wall 41A and inner wall 40B, outer wall 41B, The mutual tolerance of electrode terminal 14 of the corresponding multiple charge storage elements 11 arranged along parallel direction.In addition, passing through column variable spaced Portion 57 can correspond to the tolerance at the interval between the 1st cell columns 30 and the 2nd cell columns 31.

Left and right directions is maximum

Indicate that the tolerance in multiple charge storage elements 11 in the lateral direction becomes the interconnection module of maximum state in Fig. 2 10.In the through hole 23A in the 1st bus 37 of long hole shape, the stud 42 for being set to electrode terminal 14 is located at from passing through The position of the off-centring of perforation 23A.In addition, the 1st flexion bond 35 between the 1st adjacent unit 33 becomes on a left side The state that right upwardly extends.In addition, in the 1st sliding linking part 36 between the 1st adjacent unit 33, inner wall 40A Become minimum with the region being overlapped in the longitudinal direction outer wall 41A.In addition, connecting in the 2nd between the 2nd adjacent unit 51 In knot 52, the region that inner wall 40B and outer wall 41B are overlapped in the longitudinal direction becomes minimum.In this way, in the lateral direction, In In the state that the tolerance of multiple charge storage elements 11 becomes maximum, each tolerance state added together can be corresponded to.

On the other hand, indicate that the tolerance in multiple charge storage elements 11 in the lateral direction becomes the smallest shape in Fig. 3 The interconnection module 10 of state.In the through hole 23A in the 1st bus 37 of long hole shape, it is set to the double end spiral shell of electrode terminal 14 Bolt 42 is located at the position from the off-centring of through hole 23A.The 1st flexion bond 35 between the 1st adjacent unit 33 As the state shunk in the lateral direction.In addition, in the 1st sliding linking part 36 between the 1st adjacent unit 33, it is interior The region that wall 40A and outer wall 41A are overlapped in the longitudinal direction becomes maximum.In addition, between the 2nd adjacent unit 51 The region that 2nd linking part 52, inner wall 40B and outer wall 41B are overlapped in the longitudinal direction becomes maximum.In this case, in right and left Upwards, in the state that the tolerance of multiple charge storage elements 11 becomes minimum, each tolerance state added together can be corresponded to.

Become maximum shape in the tolerance being represented in Fig. 4 between the electrode terminal 14 of charge storage element 11 in the longitudinal direction The interconnection module 10 of state.Column variable spaced portion 57 is formed as oblong shape, and becomes the column variable spaced than indicating in Fig. 2 The state that portion 57 slightly expands in the longitudinal direction.In this case, the electrode of charge storage element 11 in the longitudinal direction can be corresponded to Tolerance between terminal 14 becomes maximum state.

Indicating the tolerance between the electrode terminal 14 of charge storage element 11 in the longitudinal direction as the smallest in Fig. 5 The interconnection module 10 of state.Column variable spaced portion 57 is formed as than column variable spaced shown in Figure 2 portion 57 in the longitudinal direction The shape being crushed.In this case, can correspond to tolerance between the electrode terminal 14 of charge storage element 11 in the longitudinal direction at For the smallest state.

In addition, according to the present embodiment, the 1st wiring portion 28 for being set to the 1st cell columns 30 has towards the 2nd cell columns 31 The 1st extension 61 extended, the 2nd wiring portion 29 for being set to the 2nd cell columns 31 have the 2nd extension 62,62 court of the 2nd extension Extend to the 1st cell columns 30, and the 2nd extension 62 is configured in a manner of at least partly be overlapped with the 1st extension 61, the 1 wiring portion 28, the 1st extension 61, the 2nd wiring portion 29 and the 2nd extension 62 are configured with voltage detecting line 16.

It can be in the 1st wiring portion 28 and the 2nd by the 1st extension 61 and the 2nd extension 62 according to above-mentioned composition Voltage detecting line 16 is laid between wiring portion 29 in a manner of erection.Accordingly, because in the wiring of voltage detecting line 16 from It is improved by degree, so voltage detecting line 16 can be easily processed in interconnection module 10.

Become maximum in the tolerance being represented in Fig. 4 between the electrode terminal 14 of charge storage element 11 in the longitudinal direction The interconnection module 10 of state.In this state, the region that the 1st wiring portion 28 and the 2nd wiring portion 29 are overlapped in the longitudinal direction at For minimum.In this case, even if the tolerance between the electrode terminal 14 of charge storage element 11 becomes maximum shape in the longitudinal direction It, also can be voltage detecting line 16 to be set up between the 1st wiring portion 28 and the 2nd wiring portion 29 by corresponding tolerance under state Mode is routed.

Indicating the tolerance between the electrode terminal 14 of charge storage element 11 in the longitudinal direction as the smallest in Fig. 5 The interconnection module 10 of state.In this state, the region that the 1st wiring portion 28 and the 2nd wiring portion 29 are overlapped in the longitudinal direction at For maximum.In this case, even if the tolerance between the electrode terminal 14 of charge storage element 11 becomes the smallest shape in the longitudinal direction Tolerance is corresponded under state, so as to voltage detecting line 16 to be set up in the mode between the 1st wiring portion 28 and the 2nd wiring portion 29 It is routed.

(4) the 1st linking parts are not limited to the shape being formed as one with the 1st unit 33, can also be separately formed.Separately Outside, the 2nd linking part is not limited to the shape being formed as one with the 2nd unit 51, can also be separately formed.

(5) in the above-described embodiment, the 1st bus 37 and the 2nd bus 54 are set as carrying out heteropolar electrode terminal 14 It connects (charge storage element 11 is connected in series), but not limited to this, it also can be set to for the electrode terminal 14 of homopolarity to be attached and (incite somebody to action Charge storage element 11 is connected in parallel).For example, it is also possible to further be connected in parallel other using the interconnection module in above embodiment Charge storage element 11, be electrically connected by the electrode terminal 14 of the homopolarity being connected in parallel.

(6) quantity of charge storage element 11 can be selected arbitrarily.
