Abstract: The present application provides a bracket and a cell contact system assembly. The bracket includes a bracket body, an elastic member and a position-limiting member. A fixed end of the elastic member and a fixed end of the position-limiting member are assembled on the bracket body. The position-limiting member, the elastic member and the bracket body enclose to define a position-limiting space. An end of the elastic member away from the fixed end of the elastic member is a free end. An end of the position-limiting member away from the fixed end of the position-limiting member is a position-limiting end. A guiding opening defined between the free end of the elastic member and the position-limiting end of the position-limiting member is communicated with the position-limiting space. The guiding opening has a size being adjusted by changing a degree of deformation of the free end of the elastic member.
