연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A storage battery comprising: a terminal portion for storage batteries having a plurality of bolt insertion holes bored in one or a plurality of directions, a nut insertion opening through which a nut is inserted, and a hollow in communication with the bolt insertion holes and the nut insertion opening; andthe nut having at least one screw hole threaded in a direction coincident with the at least one or a plurality of directions,wherein the terminal portion further comprises a fixation portion that fixes the nut to the terminal portion such that the nut does not fall when the nut insertion opening faces downward in a vertical direction, the fixation portion being formed by deforming the terminal portion in a state where the nut is inserted through the nut insertion opening into the hollow and the at least one screw hole of the nut is in communication respectively with the at least one of the plurality of bolt insertion holes. 2. The storage battery according to claim 1, wherein the fixation portion is a projecting portion projecting in the hollow direction in a part, facing the hollow, on an inner surface of the terminal portion. 3. The storage battery according to claim 1, wherein the fixation portion is a part of the nut insertion opening that is narrowed after the nut is inserted into the hollow of the terminal portion. 4. The storage battery according to claim 3, wherein the hollow of the terminal portion is elongated in a direction in which the nut is inserted, andthe nut is arranged at a position on the back side, as seen from the nut insertion opening of the hollow of the terminal portion. 5. The storage battery according to claim 1, wherein the fixation portion is a part of a sidewall or ceiling of the terminal portion in which a recess is provided after the nut is inserted into the hollow of the terminal portion. 6. The storage battery according to claim 1, wherein the plurality of bolt insertion holes are bored at such positions as not to intersect each other within the hollow of the terminal portion, andthe plurality of screw holes of the nut are formed at such positions as not to intersect each other. 7. The storage battery according to claim 1, wherein the plurality of bolt insertion holes are bored at such positions as to intersect each other within the hollow of the terminal portion, andthe plurality of screw holes of the nut are formed at such positions as to intersect each other. 8. The storage battery according to claim 1, wherein the hollow of the terminal portion has a large width at the nut insertion opening and a reduced width on the back side. 9. The storage battery according to claim 1, wherein the storage battery comprises a plastic encapsulated terminal for storage batteries comprising: the terminal portion;a pole portion coupled to a lower end of the terminal portion; anda plastic portion surrounding a circumferential surface of the pole portion. 10. A method for producing the storage battery according to claim 1, the method comprising: a step of fixing the nut by deforming the terminal portion with the nut being inserted through the nut insertion opening into the hollow and the at least one screw hole of the nut being in communication respectively with the at least one of the plurality of bolt insertion holes. 11. The method according to claim 10, wherein the nut is fixed, after the nut is inserted into the hollow, by narrowing the nut insertion opening through application of a pressure, or providing a recess on a sidewall or ceiling of the terminal portion. 12. The method according to claim 10, wherein the nut is fixed, after the nut is inserted into the hollow, by deforming the terminal portion by heating. 13. The method according to claim 10, wherein the nut is fixed, after the nut is inserted into the hollow of the terminal portion, by placing the terminal portion into a plastic mold for plastic molding and applying a pressure to a wall of the terminal portion using a pressing pin provided in the plastic mold for plastic molding, thereby providing a recess on the wall. 14. The storage battery according to claim 1, further comprising: a battery case inside of which is partitioned by partition walls into a plurality of cells and in which an electrode assembly is housed in each of the cells; anda cover lying over the battery case from above, whereinthe cover comprises the terminal portion. 15. An automobile equipped with the storage battery according to claim 14. 16. A terminal portion for storage batteries comprising: a plurality of bolt insertion holes bored in one or a plurality of directions;a nut insertion opening through which a nut is inserted;a hollow in communication with the bolt insertion holes and the nut insertion opening; anda fixation portion that fixes the nut to the terminal portion such that the nut does not fall when the nut insertion opening faces downward in a vertical direction, the fixation portion being formed by deforming the terminal portion in a state where the nut is inserted through the nut insertion opening into the hollow and the at least one screw hole of the nut is in communication respectively with the at least one of the plurality of bolt insertion holes. 17. The storage battery according to claim 1, wherein the fixation portion is provided on a sidewall on a back surface side opposite to a front surface on which one of the plurality of bolt insertion holes is bored, a sidewall at a point where the one of the plurality of bolt insertion holes is not bored or a ceiling at a point where another one of the plurality of bolt insertion holes is not bored. 18. The storage battery according to claim 16, wherein the fixation portion is provided on a sidewall on a back surface side opposite to a front surface on which one of the plurality of bolt insertion holes is bored, a sidewall at a point where the one of the plurality of bolt insertion holes is not bored or a ceiling at a point where another one of the plurality of bolt insertion holes is not bored.
