Secondary battery
First Claim
1. A secondary battery comprising:
- a case having first and second flat end portions;
a generator unit installed in the case, the generator unit including a plurality of positive and negative electrode plates which are alternatively put on one another placing therebetween separator plates;
positive and negative flat terminals respectively held by the first and second end portions of the case, each of the flat terminals including an inside part exposed to an interior of the case and connected to corresponding ones of the positive and negative electrode plates, a middle part actually held by corresponding one of the first and second flat end portions of the case and an outside part exposed to the outside of the case; and
a reinforcing structure associated with the first and second flat end portions of the case to assure and reinforce the holding of the middle part of each flat terminal by corresponding one of the first and second flat end portions of the case.

Abstract
A secondary battery comprises a case having first and second flat end portions. A generator unit is installed in the case. The generator unit includes a plurality of positive and negative electrode plates which are alternatively put on one another placing therebetween separator plates. Positive and negative flat terminals are respectively held by the first and second end portions of the case. Each of the flat terminals includes an inside part exposed to an interior of the case and connected to corresponding ones of the positive and negative electrode plates, a middle part actually held by corresponding one of the first and second flat end portions of the case and an outside part exposed to the outside of the case. A reinforcing structure is associated with the first and second flat end portions of the case to assure and reinforce the holding of the middle part of each flat terminal by corresponding one of the first and second flat end portions of the case.

13. A secondary battery comprising:
-
a case having first and second flat end portions;
a generator unit installed in the case, the generator unit including a plurality of positive and negative electrode plates which are alternatively put on one another placing therebetween separator plates;
positive and negative flat terminals respectively held by the first and second end portions of the case, each of the flat terminals including an inside part exposed to an interior of the case and connected to corresponding ones of the positive and negative electrode plates, a middle part actually held by corresponding one of the first and second flat end portions of the case and an outside part exposed to the outside of the case;
a first projected portion possessed by the first end portion of the case, the first projected portion being put on both surfaces of the positive flat terminal and extending toward a leading end of the positive flat terminal; and
a second projected portion possessed by the second end portion of the case, the second projected portion being put on both surfaces of the negative flat terminal and extending toward a leading end of the negative flat terminal. - View Dependent Claims (14, 15)

16. A secondary battery comprising:
-
a case having first and second flat end portions;
a generator unit installed in the case, the generator unit including a plurality of positive and negative electrode plates which are alternatively put on one another placing therebetween separator plates;
positive and negative flat terminals respectively held by the first and second end portions of the case, each of the flat terminals including an inside part exposed to an interior of the case and connected to corresponding ones of the positive and negative electrode plates, a middle part actually held by corresponding one of the first and second flat end portions of the case and an outside part exposed to the outside of the case;
a first sealing layer of melted plastic film through which the middle part of the positive flat terminal is held by the first flat end portion of the case; and
a second sealing layer of melted plastic film through which the middle part of the negative flat terminal is held by the second flat end portion of the case, wherein each of the first and second sealing layers has an outside edge that projects by a given degree from a leading edge of corresponding one of the first and second flat end portions of the case toward a leading end of the outside part of the corresponding one of the positive and negative flat terminals.
