飛び出しを防止したものである。However, since the insulating member constituting the external electrode lead-out terminal portion is formed of a synthetic resin, the electrode lead-out pin is formed by caulking the electrode lead-out pin to perform the conductive connection and the sealing of the external electrode lead-out terminal portion. Although the insulating member also deforms with the deformation, since the external electrode extraction terminal portion is provided in the concave portion, the wall surface of the concave portion is restricted and the upper portion is deformed. Therefore, in the present invention, the upper surface of the insulating member is formed by forming a concave portion having a curved surface concentric with the electrode lead-out pin in a portion located above the bottom surface of the insulating member on the wall surface of the concave portion provided in the lid.

る。FIG. 1 is a diagram illustrating a sealed battery according to the present invention. FIG. 1A is a plan view of the lid of the sealed battery as viewed from above. The electrode lead-out pins 5 are inserted into the recesses 4 provided in the metal plate 3 of the header 6 by the external insulating plate 10 and the positive electrode lead-out terminal 11.
The hole is sealed by caulking the electrode lead-out pin 5 and a recess 13 is further formed on the wall surface of the recess 4 to a position below the outer insulating plate.

As shown in the sectional view shown by the line, a recess 13 is further formed in the recess of the metal plate 5 of the header. Electrode lead-out pin 4
When the inner insulating plate 9 is caulked, the inner insulating plate 9 is pressed by an increase in diameter due to the deformation of the electrode lead-out pin 4 and the other is restricted by the metal plate 3 of the header, so that the inner insulating plate 9 is deformed upward by the pressing of the inner insulating plate. As a result, an internal insulating plate deformed portion 9A is generated. Therefore, the outer insulating plate 10 is pressed from the inside, the inner diameter increases, and the outer insulating plate 10 is deformed outward.

Further, the size of the recess is determined by the caulking size of the electrode lead-out pin, so that it can be set according to the size of the caulking.

The external insulating plate is greatly deformed by the force that acts on it and protrudes to the top, but for the part where the distance between the other side and the external lead-out pin is large, the deformation of the external insulating plate due to the deformation at the time of caulking is small. It is not necessary to provide a recess.

It may be something. When the insulating member is formed integrally with the metal plate of the lid portion forming the header by insert molding or the like, the thickness can be reduced as compared with the case where the insulating member is formed of a plurality of members. Therefore, the size of the header can be reduced. Further, the number of header assembling steps can be reduced. Examples of the insulating member include a thermoplastic fluororesin such as polypropylene or a tetrafluoroethylene-perfluoroalkoxyethylene copolymer (PFA) or a tetrafluoroethylene-hexafluoropropylene copolymer (FEP).

The terminal for conductive connection is formed together with the positive electrode lead terminal plate 11 by caulking from above and below, and the integrated header 6 is formed. The electrode lead-out pins 5 are inserted into the through holes provided in the internal insulating plate 9, and the flanges 5 </ b> A and the columnar portions 5 </ b> B of the electrode lead-out pins are in close contact with the internal insulating plate 9. Further, as the electrode lead-out pin, it is preferable to use a material obtained by processing a metal material made of aluminum or an alloy thereof into the shape of the electrode lead-out pin and then annealing it. The amount of deformation of the annealed electrode lead pin is small,
As a result, the amount of deformation of each component such as the internal insulating plate and the metal plate is also small.

As a result, the airtightness between the electrode lead-out pins and the insulating member is maintained, so that a battery having good sealing characteristics can be obtained. Furthermore, the tip of the positive electrode lead-out pin maintains a substantially circular shape even after caulking, and is located at the center of the positive electrode lead terminal plate, which facilitates positioning when a conductor is connected. The electrode lead-out pins are uniformly deformed during caulking by annealing, and the surface hardness is reduced, and cracks on the surface are less likely to occur, so that the sealing performance with the insulating member is good.

The hardness of the electrode lead pins temporarily decreases due to annealing, but work hardening occurs due to the impact applied by caulking, so the electrode lead pins after caulking show the same hardness as those not subjected to annealing processing. As a result, there is no reduction in the sealing characteristics or in the caulking strength of the electrode lead-out pin.
