Patent ID: 11095006

Abstract:
A terminal structure satisfies the relationships of D1<T1<D2 andT1<T2=D2 where D1 is the length of a body part of a secondary battery, D2 is the total length of the secondary battery, T1 is a first inter-contact-terminal distance between a portion of a positive-electrode-side contact terminal and a portion of and a negative-electrode-side contact terminal when the secondary battery is not present between the positive-electrode-side contact terminal and the negative-electrode-side contact terminal, and T2 is a second inter-contact-terminal distance between the portion of the positive-electrode-side contact terminal and the portion of and the negative-electrode-side contact terminal when the secondary battery is held between the positive-electrode-side contact terminal and the negative-electrode-side contact terminal, the portion of the positive-electrode-side contact terminal and the portion of the negative-electrode-side contact terminal coming into contact with the positive electrode terminal and the negative electrode terminal of the secondary battery, respectively.
