Cell wiring module

Abstract

A cell wiring module is configured to include a plurality of connection members connecting adjacent electrode terminals of a plurality of single cells having positive and negative electrode terminals. The cell wiring module includes a first unit housing a housed connection member, and a second unit connected to the first unit by a linking connection member different from the housed connection member. Sliding occurs in the connection direction of the connection members between the linking connection member for connection and at least one of the first unit and the second unit.

1 . A cell wiring module comprising:
 a plurality of connection members connecting adjacent electrode terminals of a plurality of single cells having positive and negative electrode terminals;   a first unit housing a first one of the connection members; and   a second unit connected to the first unit by a second one of the connection members different from the first connection member,   wherein sliding occurs in a connection direction of the connection members between the second connection member and at least one of the first unit and the second unit.   
     
     
         2 . The cell wiring module according to  claim 1 , wherein the connection members include an engaged portion, and at least one of the first unit and the second unit includes an engagement portion configured to engage with the engaged portion with a predetermined clearance in the connection direction. 
     
     
         3 . The cell wiring module according to  claim 2 , wherein the engaged portion is provided at a plurality of locations in the connection direction. 
     
     
         4 . The cell wiring module according to  claim 1 , wherein one of the first unit and the second unit includes a fitting projection projecting in the connection direction of the connection member, and the other of the first unit and the second unit includes a fitting recess fitting together with the fitting projection. 
     
     
         5 . The cell wiring module according  claim 1 , wherein the connection members for connection between the first unit and the second unit are placed on base plates, and each of the base plates are fitted together. 
     
     
         6 . The cell wiring module according to  claim 1 , wherein the first unit and the second unit have identical shapes. 
     
     
         7 . The cell wiring module according to  claim 1 , wherein the connection members are attached to both the first unit and the second unit in a plurality of rows,
 of ends of the first unit on the second unit side, an end corresponding to a first row of the connection members protrudes toward the second unit more than an end corresponding to a second row of the connection members, and   of ends of the second unit on the first unit side, an end corresponding to the second row of the connection members protrudes toward the first unit more than an end corresponding to the first row of connection members.   
     
     
         8 . The cell wiring module according to  claim 1 , wherein the first unit and the second unit include positioners configured to position with respect to the single cells. 
     
     
         9 . A cell wiring module, wherein the cell wiring module according to  claim 1  is fixated to the single cells by inserting a pole-shaped terminal or a shaft of a bolt through a through-hole of the connection member, and
 the through-hole has an elliptical shape long in the connection direction of the connection member. 
 
     
     
         10 . The cell wiring module according to  claim 1 , wherein
 the plurality of single cells have a flat shape and are aligned in a long axis direction of a surface having the electrode terminals, and   the connection member connects the electrode terminals adjacent to each other in the long axis direction.   
     
     
         11 . The cell wiring module according to  claim 10 , wherein
 the plurality of single cells are aligned in a short axis direction of a surface having the electrode terminals, and   the connection member connects the electrode terminals aligned in the short axis direction.
