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.

There is provided a storage battery, including: a container having at least one cell chamber; a lid body (2) made of synthetic resin for covering a top opening of the container, the lid body having on a top surface a recessed portion that is recessed downward, the lid body having positive and negative electrode terminals disposed close to one side of the lid body and respectively at both end portions of said one side in a longitudinal direction, wherein the positive and negative electrode terminals (4) respectively have lower portions embedded in the lid body and upper portions projecting from the lid body; and an auxiliary lid (9) for closing the recessed portion. Conventional production of the storage battery has problems, for example, in that: when embedding a portion of a terminal to a lid body by insert molding, difference in shrinkage is caused between a surface in which a terminal body is embedded and a surface on which the terminal body is exposed, which results in difficulty in fitting the lid body to the container. The present invention is intended to solve this problem, for example, by providing the lid body of the storage battery with projections (6T, 7T), each at a location at which the upper portion of each of the terminals projects, at a location proximate to the location at which the upper portion of each of the terminals 4 projects, or at each of these locations.

1. A storage battery, comprising: a container having at least one cell chamber;a lid body made of synthetic resin for covering a top opening of the container, the lid body having on a top surface, a recessed portion that is recessed downward and has a bottom surface on which at least one exhaust hole for communicating with the cell chamber is formed, the lid body having positive and negative electrode terminals disposed close to one side of the lid body and respectively at both end portions of said one side in a longitudinal direction, wherein the positive and negative electrode terminals respectively have lower portions embedded in the lid body and upper portions projecting from the lid body; anda lid body cover for closing the recessed portion to form a space,wherein electrode plates are housed in the cell chamber, and the recessed portion of the lid body has bushings to which electrode poles extending from the electrode plates are respectively inserted and welded: and conductive parts respectively connecting the corresponding terminal with the corresponding bushing, the conductive parts each being integrated with the corresponding bushing and the corresponding terminal to form a terminal body, andwherein the bushings are arranged in the space and the space is separated into a space for collecting gas exhausted from the exhaust hole and a space in which the bushings are arranged,wherein at least the lower portion of each of the bushings and each of the conductive parts are embedded in the lid body by insert molding, andwherein the lid body has a projection to prevent the lid body from being convexly deformed to the front side, formed at a location at which the upper portion of each of the terminals projects, at a location proximate to the location at which the upper portion of each of the terminals projects, or at each of these locations. 2. The storage battery according to claim 1, wherein the end of each of the electrode pole welded to the corresponding bushing and the end of each of the bushing embedded in the lid body are covered with synthetic resin. 3. The storage battery according to claim 1, wherein the lid body cover for closing the recessed portion in the top surface of the lid body has a rib on a back surface and the lid body has a rib provided on the top surface of the lid body in such a manner as to oppose the rib of the lid body cover and surround a part or a whole of the periphery of each of the bushings. 4. The storage battery according to claim 1, wherein each of the bushings is of a tapered shape having an inner diameter of the upper portion smaller than that of the lower portion, and each of the electrode poles is of a tapered shape having an outer diameter of the lower end larger than that of the upper end. 5. The storage battery according to claim 1, wherein one of the lid body and the lid body cover has to-be-locked portions and the other has locking portions that come into locking engagement with the to-be-locked portions, the to-be-locked portions comprising a pair of holes, one of the pair of holes being sized to block horizontal movement of the locking portion that comes into locking engagement with the hole, the other of the pair of holes being shaped into a long hole that extends in the direction in which the pair of holes oppose each other. 6. The storage battery according to claim 1, wherein the projection comprises: a first projecting portion disposed in a periphery of the location at which the upper portion of the corresponding terminal projects; and second and third projecting portions disposed in proximity to the first projecting portion, at both sides of the first projecting portion in the longitudinal direction, and projecting upward of the first projecting portion, wherein each of the terminal has, in its side end close to the second projecting portion or in its side end close to the third projecting portion, an opening for inserting a nut, and a bottom surface of the opening is positioned lower than the top surface of the second or third projecting portion. 7. The storage battery according to claim 1, wherein the conductive part of at least one of the terminal bodies has a synthetic resin layer covered thereon, which is formed by insert molding, in such a manner as to be partly omitted or partly thinner than in other portions. 8. The storage battery according to claim 7, wherein each of the conductive parts has at least one of an annular outwardly projecting portion, an annular depressed portion and a portion whose cross sectional area is smaller than the other portions. 9. The storage battery according to claim 1, wherein the lid body cover is configured to close the recessed portion in such a manner as to cover the upper portion of the bushing. 10. The storage battery according to claim 1, wherein the terminals are disposed in cutouts which are formed at the opposite ends of one of the longitudinal sides respectively. 11. The storage battery according to claim 1, wherein the recessed portion of the lid body has a bottom wall constituting a bottom portion and a vertical wall standing upright from an outer periphery of the bottom wall, and the bushing is embedded in the bottom wall. 12. The storage battery according to claim 11, wherein the projection is molded to be integrated with the vertical wall.
