【従来の技術】従来の鉛蓄電池には、蓋と金属端子との気密性を確保するために、樹脂接着剤による気密構成と樹脂製ブッシングを使用したダブル・インジェクション成形による気密構成とが一般的に行われていた。 BACKGROUND OF THE INVENTION Conventional lead-acid batteries, in order to ensure the airtightness between the lid and the metal terminal, the airtight structure and is generally due to the double injection molding using an airtight structure and the resinous bushing by a resin adhesive It was done.

【0003】以下、その両構成について、図3を用いて説明する。 [0003] Hereinafter, for the two configurations, will be described with reference to FIG.

【0004】図3において、1は鉛合金からなる極柱であって樹脂製蓋2の開口部より突出した端子となる金属製ブッシング3の開口部3aに挿入してバーナー溶接により金属製ブッシング3に密接するように一体に構成されている。 [0004] In FIG. 3, 1 is a metallic bushing 3 by insert and burner welded to the opening portion 3a of the metallic bushing 3 serving as a terminal projecting from the opening of the resin lid 2 a pole columns made of lead alloy It is integrally formed so as to close in.

【0005】前記樹脂製蓋2は正極,負極,セパレータ,電解液などの電池要素を収納する電槽の上部口縁部に熱溶着されるものであるが、樹脂製蓋2と前記金属製ブッシング3との間の隙間を密封するために図3(a) [0005] The resinous cover 2 positive electrode, a negative electrode, a separator, and the upper opening edge of the container for accommodating the battery element such as an electrolytic solution are those heat-welded, the metal bushing and the resin lid 2 3 Figure to seal the gap between the 3 (a)
に示す樹脂接着剤封止の構成と図3(b)に示す樹脂製ブッシングを使用した構成とがある。 There is a configuration using a resin bushing shown in structure and Figure 3 (b) of the resin adhesive sealing shown.

【0006】すなわち、図3の(a)において4は樹脂製蓋2の開口部より突出した金属製ブッシング3と前記樹脂製蓋2の開口部間の間隙に充填されたエポキシ樹脂などの接着剤層であって、この接着剤層4により金属製ブッシング3と樹脂製蓋2とは強固に接着され、金属製ブッシング3と樹脂製蓋2との間より電槽内の電解液が漏出することはない。 Namely, an adhesive such as epoxy resin 4 is filled in the gaps between the openings of the metal bushing 3 and the resin lid 2 protruding from the opening of the resin cap 2 at (a) in FIG. 3 a layer, this by the adhesive layer 4 is firmly bonded to the metal bushing 3 and the resin lid 2, the electrolyte in the battery case than between the metallic bushing 3 and the resin lid 2 leaks no.

【0007】また、図3の(b)に示す5は樹脂製ブッシングで、金属製ブッシング3の外周にダブル・インジェクション方式によって気密かつ液密に成型されている。 Further, the 5 shown in FIG. 3 (b) a resin bushing is molded in an airtight and liquid-tight by the double injection method on the outer periphery of the metal bushing 3.

【0008】そして前記する樹脂製ブッシング5の外周と樹脂製蓋2の開口部とは樹脂同士の溶着接合により強固に固着されている。 [0008] Then the outer periphery opening of the resin cap 2 of resin bushing 5 to the is firmly fixed by welding bonding between the resins. 従って金属製ブッシング3と樹脂製ブッシング5との間ならびに樹脂製ブッシング5と樹脂製蓋2の開口部との間より電槽内の電解液が漏出することはない。 Therefore it does not leak electrolyte in the battery case than between and between the resin bushing 5 and the opening of the resin lid 2 of the metal bushing 3 and the resin bushing 5.

【0009】 [0009]

【発明が解決しようとする課題】しかし、図3の(a) [SUMMARY OF THE INVENTION] However, in FIGS. 3 (a)
に示す接着剤方式によれば、金属製ブッシング3,樹脂製蓋2、そして、接着剤層4などの収縮率がそれぞれ異なるため、温度条件の厳しい環境下での蓄電池の使用では材料歪みによる隙間や割れなどが起こる。 According to the adhesive system shown in, metallic bushing 3, a resin cover 2 And, since the shrinkage of an adhesive layer 4 are different, clearance due to material strain with the use of storage batteries in harsh environments of temperature conditions etc. and cracking occurs. これは、個々の材料の収縮率の違いと蓄電池内部の圧力によるものとがある。 This may as those of the individual differences and battery internal pressure of the shrinkage of the material. 隙間などが発生すると、蓄電池内部の硫酸分が極柱1から金属製ブッシング3と接着剤層4ならびに樹脂製蓋2との隙間を通じて、外部に漏洩して、電池端子は硫酸によって腐食され、最終的には、端子と配線されているターミナルも硫酸によって、断線するおそれがある。 If such a gap is generated, through the gap of the sulfuric acid of the internal battery is a metallic bushing 3 from the terminal post 1 and the adhesive layer 4 and the resin lid 2, and leaking outside the battery terminal is corroded by sulfuric acid, the final specifically, the by even a terminal that is wired to the terminal sulfate, which may be disconnected. また、外部との気密性も懸念され、極端な気体漏洩の際には、極板,棚溶接部などの酸化の加速を引き起こしたり、電池内部の水分蒸発により電解液比重を上げて、極板に負担をかけ、極板寿命、すなわち電池寿命を短くすることが予想される。 Further, airtightness between the outside even a concern, in extreme gas leakage, electrode plate, or cause accelerated oxidation, such as shelf welds, raise the electrolyte density by water evaporation inside the battery, the electrode plate straining the electrode plate life, i.e. it is expected to shorten the battery life. 上述した問題点を解決するために、近年、図3の(b)に示す樹脂製ブッシング5 In order to solve the aforementioned problems, in recent years, resin bushing 5 shown in FIG. 3 (b)
と樹脂製蓋2とが接触する部分を溶着結合するダブル・ Double that the welding coupling portions and the resin lid 2 contacts
インジェクション方式を用いる端子構造が実施されてきたが、この手段による場合は樹脂製蓋2と樹脂製ブッシング5の両方をインジェクションモールドするダブル・ Although the terminal structure using the injection system have been conducted, double for injection molding both the resin cover 2 and the resin bushing 5 If by this means
インジェクション方式を用いるため、設備においても工数においても非常に高価となる問題点があった。 For using injection system, there has been very expensive to become a problem also in man-hour in the facility.

【0010】そこで本発明は、このような課題を解決し、蓄電池端子部における液密,気密不良の防止に適し、かつ安価で端子部の密閉構造を構成できる鉛蓄電池とその製造方法を提供することを目的とするものである。 [0010] The present invention, this problem is solved, and provides a liquid-tight, suitable for the prevention of poor airtightness, and inexpensive lead-acid battery that can be configured a sealed structure of the terminal portion between a manufacturing method in the battery terminal unit it is an object of the present invention.

【0011】 [0011]

【課題を解決するための手段】本発明は前記する目的を達成する手段として、樹脂製蓋の透孔に装着される金属製ブッシングの外周部に樹脂製ブッシングを密着して成形し、その樹脂製ブッシングの外周部と底部とに環状凹部を構成し、前記樹脂製ブッシングが密着する前記樹脂製蓋には、前記樹脂製ブッシングの環状凹部に対応する位置に環状凹部を設け、前記樹脂製ブッシングの環状凹部と前記樹脂製蓋の環状凹部とによって構成される環状溝部内に弾性体物質によって構成された弾性シール体を圧入させることによって前記樹脂製蓋に前記樹脂製ブッシングを気密でかつ液密に装着することとしたものである。 As it means present invention to achieve the purpose of the SUMMARY OF THE INVENTION, in close contact with resin bushings molded into the outer peripheral portion of the metallic bushing mounted on the through hole of the resin lid, the resin in the outer peripheral portion and the bottom portion of the manufacturing bushing constitutes an annular recess, on the resin lid the resin bushing is in close contact is an annular recess provided at a position corresponding to the annular recess of the resin bushing, the resin bushing hermetically a and liquid-tight the resin bushing on the resin lid by press-fitting the elastic seal member of an elastic body material in the annular groove formed by the annular recess of the annular recess and the resin lid of in which it was decided to be attached to.

【0012】これにより、Oリングもしくはパッキンなどの弾性シール体を有する樹脂製ブッシングを樹脂製蓋に密着させることで、前記弾性シール体が圧縮され、圧縮した弾性シール体により完全密封された状態となる。 [0012] Thus, a resin bushing having an elastic sealing member such as O-ring or gasket that is brought into close contact with the resin cover, the elastic sealing member is compressed, a state of being completely sealed by the compressed elastic sealing member Become.
また、樹脂製ブッシングならびに樹脂製蓋の環状凹部にOリングもしくはパッキンなどの弾性シール体が入り込むように、相対した構造であり、Oリングやパッキンなどの弾性シール体の装着ズレを防止している。 Also, as the elastic seal member such as O-ring or gasket enters into the annular recess of the resin bushing and the resin lid, the relative structure, thereby preventing the mounting displacement of the elastic sealing member such as O-ring and packing . その結果、金属製ブッシングと極柱の溶接時の熱や熱衝撃的な雰囲気温度などにおいても、材料収縮,膨張は、弾性シール体の特性である膨張,収縮により隙間の発生を防止することができる。 As a result, in such as a metal bushing and heat and thermal shock atmosphere temperature during welding of the pole, material shrinkage, expansion, expansion is a characteristic of the elastic seal member, it is possible to prevent the occurrence of gap due to contraction it can.

【0013】 [0013]

【発明の実施の形態】本発明において樹脂製ブッシングは金属製ブッシングに密着するように成形されるのであるが、その樹脂製ブッシングの外周ならびに底部に形成される環状凹部は樹脂製ブッシング成形時に同時形成されてもよいし、また表面が滑らかな樹脂製ブッシングを成形した後に加工によって環状凹部が形成されてもよい。 Although resin bushing DETAILED DESCRIPTION OF THE INVENTION The present invention is being molded so as to be in close contact with metallic bushing, the same time when the annular recess has a resin bushing molded to be formed on the outer peripheral and bottom of the plastic bushing it may be formed, or may be formed an annular recess by the processing after the surface has formed a smooth plastic bushing.

【0014】また、樹脂製ブッシングと樹脂製蓋とはそれぞれが密着することになるため、膨張率などが同じ同質の樹脂を使用することが好ましく、また電解液が硫酸であるため耐電解液性として耐硫酸性の樹脂を選択することが望ましい。 Furthermore, this means that each adhered to the resinous bushing and the resin lid, it is preferred that such expansion is a resin of the same homogeneous and electrolyte resistance because the electrolyte is sulfuric acid it is desirable to select a resin sulfuric acid as.

【0015】また、樹脂製ブッシングの環状溝部と樹脂製蓋の環状凹部とにより構成される溝部に圧入される弾性シール体は膨張,収縮の弾性が大きいことと、耐硫酸性を持った材質を選択することが好ましい。 Further, the elastic seal member to be press-fitted into the groove formed by the annular groove and the annular recess of the resin cover of the plastic bushing expansion, and that the elastic shrinkage is large, the material having the sulfuric acid resistance it is preferable to select.
