Description

この発明は、自動車用などに用いられる鉛蓄電池の端子部を構成する鉛蓄電池用のブッシングに関する。   The present invention relates to a bushing for a lead storage battery constituting a terminal part of a lead storage battery used for automobiles and the like.

自動車用などに用いられる鉛蓄電池は、合成樹脂製の電槽と、この電槽の上部に融着された合成樹脂製の電槽蓋と、この電槽蓋の上部に設けられた端子部とを備え、前記端子部は、電槽蓋にインサート成形された鉛合金製のブッシングと、このブッシング内に挿入された鉛合金製の極柱とで構成され、極柱がブッシングに電槽の外部において溶接されている。電槽および電槽蓋は、ABS樹脂あるいはポリプロピレン（PP）樹脂などの合成樹脂で製作されている。   A lead-acid battery used for automobiles, etc. includes a synthetic resin battery case, a synthetic resin battery case fused to the upper part of the battery case, and a terminal portion provided on the upper part of the battery case cover. The terminal portion is composed of a lead alloy bushing that is insert-molded in the battery case lid, and a lead alloy pole column that is inserted into the bushing. Are welded. The battery case and battery case cover are made of synthetic resin such as ABS resin or polypropylene (PP) resin.

端子部のブッシングは、そのほぼ下半部が電槽蓋の樹脂材料内にインサートされている。しかし、ブッシングの金属材料と電槽蓋の樹脂材料との間には実質的に接着力が生じることがなく、このためブッシングと電槽蓋とが密着せずにその間に微小な隙間が生じ、その隙間を通して電槽内の電解液が這い上がり、端子部に染み出てしてしまう恐れがある。   The lower half of the bushing of the terminal part is inserted into the resin material of the battery case lid. However, there is substantially no adhesive force between the bushing metal material and the resin material of the battery case lid. There is a possibility that the electrolyte in the battery case will crawl up through the gap and ooze out into the terminal portion.

そこで一般に、図７に示すように、ブッシング１０のほぼ下半部外周に環状突起１１を上下複数段に形成し、これら環状突起の形成部を電槽蓋１２の樹脂内にインサートし、電解液が這い上がる経路を長くしてその染み出しを防止するようにしている。このような構造は例えば特開２００３−３１７６７７公報や特開２００４−２３５０５０公報などに開示されている。なお、図７において、１３はブッシング１０内に挿入された極柱で、この極柱１３の上部がブッシング１０に溶接される。   In general, therefore, as shown in FIG. 7, annular protrusions 11 are formed in a plurality of upper and lower stages on the outer periphery of the substantially lower half of the bushing 10, and the formed portions of these annular protrusions are inserted into the resin of the battery case lid 12, The path that crawls up is lengthened to prevent it from seeping out. Such a structure is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2003-317677 and 2004-235050. In FIG. 7, reference numeral 13 denotes a pole column inserted into the bushing 10, and the upper portion of the pole column 13 is welded to the bushing 10.

ところで、鉛蓄電池の端子部には、ハーネス端子などの接続端子が接続される。自動車用の鉛蓄電池では、その接続端子を通して１００〜数１００Ａ程度の電流が、また各種非常電源用として使用される大型のバックアップ電源用の鉛蓄電池では１０００Ａ程度の大電流が流れる。このため端子部に接続端子を接続する際に、相当強力なトルクを加えながらその接続端子を端子部のブッシングに締付けて接続している。   By the way, connection terminals, such as a harness terminal, are connected to the terminal part of a lead acid battery. In a lead acid battery for automobiles, a current of about 100 to several hundreds A flows through the connection terminal, and a large current of about 1000 A flows in a lead acid battery for a large backup power source used for various emergency power supplies. For this reason, when connecting the connection terminal to the terminal portion, the connection terminal is tightened and connected to the bushing of the terminal portion while applying a considerably strong torque.

しかしその締付けのトルクでブッシングが回転してしまう恐れがある。そこで、特開２００３−３１７６７７公報では、図８に示すように、ブッシング１０における環状突起１１間に回転防止用のリブ１５を一体に形成し、このリブ１５で接続端子締付け時のトルクを受け止めてその回転を防止するようにしている。
特開２００３−３１７６７７公報 特開２００４−２３５０５０公報 However, the bushing may be rotated by the tightening torque. Therefore, in Japanese Patent Application Laid-Open No. 2003-317777, as shown in FIG. 8, a rib 15 for preventing rotation is formed integrally between the annular protrusions 11 of the bushing 10, and the rib 15 receives the torque at the time of tightening the connection terminal. The rotation is prevented.

しかしながら、ブッシングの環状突起にリブを形成すると、そのリブによりブッシングの質量および材料コストが増してしまう。鉛蓄電池は相当高重量であり、でき得る限り鉛使用量を減らして軽量化を図ることが求められているが、ブッシングに回転防止用のリブを形成すると、鉛使用量が増してその要求を満たすことができなくなり、また材料コストも増してしまう。   However, if a rib is formed on the annular protrusion of the bushing, the rib increases the mass and material cost of the bushing. Lead storage batteries are quite heavy, and it is required to reduce the amount of lead used to reduce the weight as much as possible. It cannot be satisfied and the material cost increases.

この発明はこのような点に着目してなされたもので、その目的とするところは、環状突起間に回転防止用のリブを形成しても、質量および材料コストを低減でき、さらに電解液の染み上がりをより確実に抑制でき、かつ耐締付けトルク値も高めることができる鉛蓄電池用のブッシングを提供することにある。   The present invention has been made paying attention to such points, and the object of the present invention is to reduce the mass and material cost even if the rib for preventing rotation is formed between the annular protrusions. It is an object of the present invention to provide a bushing for a lead-acid battery that can more reliably suppress oozing and increase the tightening torque value.

このような目的を達成するために、請求項１の発明は、外周面に環状突起が複数段に形成され、その互いに隣り合う環状突起間の環状溝内に回転防止用のリブが形成され、前記環状突起の形成部が鉛蓄電池の電槽蓋の樹脂材料内にインサートされる鉛蓄電池用のブッシングにおいて、前記環状突起に凹部が形成されていることを特徴としている。   In order to achieve such an object, according to the invention of claim 1, an annular protrusion is formed in a plurality of stages on the outer peripheral surface, and a rib for preventing rotation is formed in an annular groove between the adjacent annular protrusions. In the lead-acid battery bushing in which the annular protrusion is inserted into the resin material of the battery case lid of the lead-acid battery, a concave portion is formed in the annular protrusion.

請求項２の発明は、請求項１における凹部が、前記複数段の環状突起のうちの１つまたは複数に複数ずつ形成されていることを特徴としている。   The invention according to claim 2 is characterized in that a plurality of the recesses in claim 1 are formed in one or more of the plurality of stages of annular projections.

請求項３の発明は、請求項１または２における凹部が、前記環状突起の下面に形成されていることを特徴としている。   A third aspect of the invention is characterized in that the concave portion in the first or second aspect is formed on the lower surface of the annular protrusion.

請求項４の発明は、請求項１または２の凹部が、前記環状突起の外周周面に形成されていることを特徴としている。   The invention of claim 4 is characterized in that the recess of claim 1 or 2 is formed on the outer peripheral surface of the annular projection.

この発明によれば、ブッシングの環状突起に凹部を形成することでその質量および材料コストを低減できる。さらに、凹部の形成でブッシングと電槽蓋の樹脂材料との接触面積が増大し、ブッシングと電槽蓋の樹脂材料にかかる応力が低減し、これにより電解液の染み上がりをより確実に抑制でき、また凹部の形成で電槽蓋の樹脂材料がその凹部に食い込んで耐締付けトルク値を高めることができる。   According to this invention, the mass and material cost can be reduced by forming the recess in the annular projection of the bushing. Furthermore, the formation of the recess increases the contact area between the bushing and the resin material of the battery case lid, and the stress applied to the resin material of the bushing and the battery case lid is reduced. Moreover, the resin material of the battery case lid can bite into the concave portion by forming the concave portion, thereby increasing the tightening torque value.

以下、この発明の実施の形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１にはこの発明の第１の実施形態に係る鉛蓄電池のブッシング１を示してある。このブッシング１は、鉛合金からなる中空円筒状の主部２と、この主部２のほぼ下半部外周に一体に上下複数段に突出形成された環状突起３とを備えている。各環状突起３は、主部２の周方向に連続して延びる鍔形状の突起であり、その互いに隣り合う環状突起３間が環状溝４となっている。最上部の環状突起３はその外径寸法がその下側の環状突起３の外径寸法よりも大きくなっている。   FIG. 1 shows a bushing 1 of a lead storage battery according to a first embodiment of the present invention. The bushing 1 includes a hollow cylindrical main portion 2 made of a lead alloy, and an annular protrusion 3 that is integrally formed on the outer periphery of the lower half of the main portion 2 so as to protrude in a plurality of stages. Each annular protrusion 3 is a hook-shaped protrusion continuously extending in the circumferential direction of the main portion 2, and an annular groove 4 is formed between the adjacent annular protrusions 3. The outermost diameter of the uppermost annular protrusion 3 is larger than the outer diameter of the lower annular protrusion 3.

そしてこの実施形態のブッシング１においては、上から１段目の大径の環状突起３の下側の環状溝４内に回転防止用のリブ５が複数一体に形成されている。これらリブ５は環状突起３の周方向に沿って一定の間隔をあけて並ぶように形成されている。   In the bushing 1 of this embodiment, a plurality of ribs 5 for preventing rotation are integrally formed in the annular groove 4 below the large-diameter annular protrusion 3 in the first step from the top. These ribs 5 are formed so as to be arranged at regular intervals along the circumferential direction of the annular protrusion 3.

さらに、１段目の環状突起３およびその下側の２段目の環状突起３には、それぞれ複数ずつ凹部として矩形状の凹み６が形成されている。これら凹み６はそれぞれ環状突起３の周方向に沿って離間する任意の位置において、それぞれ環状突起３の下面に形成されている。   Furthermore, a rectangular recess 6 is formed as a plurality of recesses on each of the first-stage annular protrusion 3 and the second-stage annular protrusion 3 below the first-stage annular protrusion 3. These recesses 6 are respectively formed on the lower surface of the annular protrusion 3 at arbitrary positions separated along the circumferential direction of the annular protrusion 3.

なお、凹み６の形状としては、矩形状の場合に限らず、金型での型抜きが可能であれば、三角形状、四角形状、トラック形状などであってもよい。そしてこのブッシング１は、環状突起３の形成部が電槽蓋の樹脂内にインサートされ、ブッシング１の中空内に極柱が挿入され、この極柱の上部がブッシング１に溶接される。   The shape of the recess 6 is not limited to a rectangular shape, and may be a triangular shape, a quadrangular shape, a track shape, or the like as long as it can be punched with a mold. In the bushing 1, the formation portion of the annular protrusion 3 is inserted into the resin of the battery case lid, the pole column is inserted into the hollow of the bushing 1, and the upper portion of the pole column is welded to the bushing 1.

このようなブッシング１においては、各環状突起３により電解液の這い上がり経路を長くして端子部への電解液の染み出しを防止することができ、また接続端子締付け時のトルクを各リブ５で受け止めてブッシング１の回転を防止することができる。   In such a bushing 1, each annular projection 3 makes it possible to lengthen the path of the electrolyte so as to prevent the electrolyte from seeping out to the terminal portion, and the torque at the time of tightening the connection terminal can be set to each rib 5. And the bushing 1 can be prevented from rotating.

そして、リブ５の形成により鉛使用量が増えているが、環状突起３に複数の凹み６が形成されているため、そのリブ５による鉛の使用量の増大は各凹み６の容積分で打ち消され、ブッシング１の全体での鉛使用量の増加を抑えることができる。したがって、このブッシング１を用いることで鉛蓄電池の軽量化を図れ、また鉛材料の削減によってコストを低減することができる。   The amount of lead used is increased due to the formation of the ribs 5, but since the plurality of recesses 6 are formed in the annular protrusion 3, the increase in the amount of lead used by the ribs 5 is canceled by the volume of each recess 6. Therefore, an increase in the amount of lead used in the entire bushing 1 can be suppressed. Therefore, the use of the bushing 1 can reduce the weight of the lead-acid battery and can reduce the cost by reducing the lead material.

図２にはこの発明の第２の実施形態に係る鉛蓄電池のブッシング１を示してある。このブッシング１においては、１段目と２段目との環状突起３間の環状溝４内に回転防止用の複数のリブ５が形成され、１段目の環状突起３の下側の各環状突起３における外周周面に凹部として縦方向に延びる筋状の溝７がそれぞれ多数ずつ形成されている。   FIG. 2 shows a bushing 1 of a lead storage battery according to a second embodiment of the present invention. In the bushing 1, a plurality of ribs 5 for preventing rotation are formed in an annular groove 4 between the first-stage and second-stage annular protrusions 3. A large number of streak-like grooves 7 extending in the vertical direction as recesses are formed on the outer peripheral surface of the protrusion 3.

図３にはこの発明の第３の実施形態に係る鉛蓄電池のブッシング１を示してある。このブッシング１においては、１段目と２段目との環状突起３間の環状溝４内に回転防止用の複数のリブ５が形成され、１段目の環状突起３とその下側の２段目の環状突起３における下面にそれぞれ凹部として複数の凹み６が形成され、さらに３段目および４段目の環状突起３の外周周面にそれぞれ凹部として複数の縦方向に延びる筋状の溝７が形成されている。   FIG. 3 shows a bushing 1 of a lead storage battery according to a third embodiment of the present invention. In this bushing 1, a plurality of ribs 5 for preventing rotation are formed in an annular groove 4 between the first and second annular projections 3, and the first annular projection 3 and the lower two of the annular projections 3 are provided. A plurality of dents 6 are formed as recesses on the lower surface of the annular projection 3 at the step, and a plurality of streak-like grooves extending in the vertical direction as recesses on the outer circumferential surface of the third and fourth annular projections 3 respectively. 7 is formed.

図４にはこの発明の第４の実施形態に係る鉛蓄電池のブッシング１を示してある。前記第１および第２の実施形態におけるブッシング１では、主部２のほぼ下半部の外周に環状突起３が５段に亘って形成されているが、この実施形態のブッシング１では環状突起３が３段に亘って形成されている。そして、上から１段目と２段目の環状突起３の下面に凹部として複数の凹み６が形成され、さらに３段目の環状突起３の外周周面に凹部として複数の縦方向に延びる筋状の溝７が形成されている。   FIG. 4 shows a bushing 1 of a lead storage battery according to a fourth embodiment of the present invention. In the bushing 1 in the first and second embodiments, the annular protrusion 3 is formed on the outer periphery of the substantially lower half of the main portion 2 in five stages. In the bushing 1 of this embodiment, the annular protrusion 3 is formed. Is formed over three stages. A plurality of recesses 6 are formed as recesses on the lower surfaces of the first and second annular projections 3 from above, and a plurality of longitudinally extending stripes are formed as recesses on the outer circumferential surface of the third annular projection 3. A groove 7 is formed.

図５にはこの発明の第５の実施形態に係る鉛蓄電池のブッシング１を示してある。このブッシング１では、環状突起３が５段に亘って形成され、１段目と２段目との環状突起３間の環状溝４内に回転防止用の複数のリブ５が形成され、第１段目の下面に凹部として矩形状の凹み６が形成されている。   FIG. 5 shows a bushing 1 of a lead storage battery according to a fifth embodiment of the present invention. In the bushing 1, the annular protrusion 3 is formed in five steps, and a plurality of ribs 5 for preventing rotation are formed in the annular groove 4 between the first and second annular protrusions 3. A rectangular recess 6 is formed as a recess on the lower surface of the step.

図６にはこの発明の第６の実施形態に係る鉛蓄電池のブッシング１を示してある。このブッシング１では、環状突起３が５段に亘って形成され、１段目と２段目との環状突起３間の環状溝４内に回転防止用の複数のリブ５が形成され、第２段目の外周周面に凹部とし複数の縦方向に延びる筋状の溝７が形成されている。   FIG. 6 shows a bushing 1 of a lead storage battery according to a sixth embodiment of the present invention. In this bushing 1, the annular protrusion 3 is formed over five stages, and a plurality of ribs 5 for preventing rotation are formed in the annular groove 4 between the first and second annular protrusions 3. A plurality of streak-like grooves 7 extending in the vertical direction are formed on the outer peripheral surface of the step.

前記第１〜第６の実施形態に係るブッシング１を、本発明品１〜６としてそれぞれ所定形状の金型を用い、金型温度１８０〜２４０℃、鉛合金溶湯温度４００〜４４０℃の条件で重力鋳造により作製し、また図８に示すブッシング１０を従来品１として同じ条件で作製した。そして、これら本発明品１〜６のブッシング１および従来品１のブッシング１０について、相対質量比、面積比、耐締付けトルク値を測定した。この測定の結果を次の表１に示す。   The bushing 1 which concerns on the said 1st-6th embodiment uses the metal mold | die of a predetermined shape as this invention products 1-6, respectively, on the conditions of mold temperature 180-240 degreeC and lead alloy molten metal temperature 400-440 degreeC. The bushing 10 shown in FIG. 8 was manufactured under the same conditions as the conventional product 1 by gravity casting. And about these bushings 1 of this invention products 1-6 and the bushing 10 of the conventional product 1, the relative mass ratio, the area ratio, and the tightening torque value were measured. The results of this measurement are shown in Table 1 below.

なお、相対質量比および面積比は従来品１を１００％としたときの比率である。また、面積比は、回転防止用のリブ、各環状突起、各環状溝の表面積を合算して比較した比率である。また、耐締付けトルク値は、ＪＩＳ−Ｄ５３０１に記載の方法に基づいて測定した。

Figure 2009259541
The relative mass ratio and the area ratio are ratios when the conventional product 1 is 100%. The area ratio is a ratio obtained by adding and comparing the surface areas of the rib for preventing rotation, each annular protrusion, and each annular groove. The tightening torque value was measured based on the method described in JIS-D5301.
Figure 2009259541

この表に示されるように、本発明品１〜６においては、ブッシング１に凹部としての凹み６や溝７を形成することにより、従来品１に比べ質量が低減していることが分かる。   As shown in this table, in the products 1 to 6 of the present invention, it is understood that the mass is reduced as compared with the conventional product 1 by forming the recess 6 or the groove 7 as the recess in the bushing 1.

また、面積比を見ると、従来品１に比べ２倍以上で、耐久締付けトルク値が１．４倍以上となっている。これは、凹部としての凹み６や溝７を形成することで、電槽蓋の樹脂材料がその各凹み６や溝７内に入り込んで食い込み、その樹脂材料との接触面積が増すことで、耐締付けトルク値が従来品１よりも増大しているものである。   Moreover, when the area ratio is seen, it is twice or more compared with the conventional product 1, and the durable tightening torque value is 1.4 times or more. This is because the resin material of the battery case lid penetrates into each of the recesses 6 and the grooves 7 by forming the recesses 6 and the grooves 7 as the recesses, and the contact area with the resin material is increased. The tightening torque value is higher than that of the conventional product 1.

さらに、本発明品１〜６のブッシング１および従来品１のブッシング１０を用いてそれぞれ５５Ｄ２３型の鉛蓄電池を製造し、電解液の染み上がりについて検証した。この検証にあたっては、所定期間経過後の鉛蓄電池の端子部を解体し、ブッシングの腐食の状況に基づいて電解液の染み上がりを評価した。   Furthermore, 55D23 type lead-acid batteries were manufactured using the bushing 1 of the present invention products 1 to 6 and the bushing 10 of the conventional product 1 respectively, and the bleeding of the electrolyte was verified. In this verification, the terminal part of the lead storage battery after a lapse of a predetermined period was disassembled, and the bleeding of the electrolyte was evaluated based on the state of corrosion of the bushing.

この評価によれば、従来品１に対し、本発明品１〜６では染み上がりがほとんど認められず、染み上がりをより確実に抑制できることが分かった。これは、ブッシング１の環状突起３に凹部としての凹み６や溝７を形成することで、電槽蓋の樹脂材料とブッシング１の鉛材料との接触面積が増大し、耐締付けトルク値が向上するため染み上がりが確実に抑制されるものである。   According to this evaluation, it was found that, with respect to the conventional product 1, the products 1 to 6 of the present invention showed almost no stain, and the stain could be more reliably suppressed. This is because by forming the recess 6 or groove 7 as a recess in the annular protrusion 3 of the bushing 1, the contact area between the resin material of the battery case lid and the lead material of the bushing 1 is increased, and the tightening torque value is improved. Therefore, the soaking up is surely suppressed.

特に本発明品４のブッシング１では、従来品１に比べ環状突起３の形成段数が減っているにも拘わらず、凹部５および溝７の形成で電解液の這い上がりの経路を長く確保できるため、電解液の染み上がりを良好に抑制することができ、また凹み６および溝７の形成で電槽蓋の樹脂材料との食い込みを強めて耐締付けトルク値を大きくすることができる。そして、環状突起３の形成段数の減少により質量を大幅に低減することができる。   In particular, in the bushing 1 of the product 4 of the present invention, although the number of formation steps of the annular protrusion 3 is reduced compared to the conventional product 1, the formation of the recess 5 and the groove 7 can ensure a long path for the electrolyte to rise. The penetration of the electrolytic solution can be satisfactorily suppressed, and the formation of the recess 6 and the groove 7 can increase the biting force with the resin material of the battery case lid and increase the tightening torque value. And mass can be reduced significantly by the reduction | decrease in the formation step number of the cyclic | annular protrusion 3. FIG.

以上説明したように、この発明によれば、ブッシングの環状突起に凹部を形成することにより、質量の低減を図って鉛蓄電池の軽量化を実現できるとともに、その凹部の形成に基づいて端子部の耐締付け値および電解液の染み上がりをより確実に防止することができる。   As described above, according to the present invention, by forming a recess in the annular protrusion of the bushing, the weight of the lead storage battery can be reduced by reducing the mass, and the terminal portion is formed based on the formation of the recess. It is possible to prevent the tightening value and the electrolyte from bleeding more reliably.
