201013081 六、發明說明： 【發明所屬之技術領域】 本發明係有關燃料電池用插座，及使用其之燃料電池 用聯結器及燃料電池。 【先前技術】 近年來，爲可長時間不需充電使用筆記型電腦或行動 0 電話等各種攜帶式電子機器，人們正嚐試使用燃料電池於 該等攜帶式電子機器之電源。燃料電池只要供給燃料與空 氣即可發電’只要補給燃料即可連續長時間發電。因此， 只要可以縮小燃料電池，即可成爲攜帶用電子機器之電源 之極有益之系統。 尤其是，利用能源密度高的甲醇燃料之直接甲醇型燃 料電池（DMFC: Direct methanol fuel cell)可以小型化 ，且燃料之處理容易，所以被認爲有希望做爲攜帶式機器 φ 之電源。已知的DMFC的液體燃料之供給方式有氣體供給 型與液體供給型等之主動（active )方式，或在電池內部 使燃料槽內之液體燃料氣化而供給給燃料極的內部氣化型 等之被動（passive )方式。其中，被動方式有利於DMFC 的小型化。 內部氣化型之被動型DMFC中，係透過燃料含浸層或 燃料氣化層等氣化燃料收容部內的液體燃料，而供給至燃 料極（參照例如專利文獻1〜2 )。對此種燃料收容部之 甲醇燃料之供給係利用例如衛星型（外部注入式）之燃料 -5- 201013081 盒。 利用燃料盒供給甲醇燃料時，通常使用由插座（ socket)與栓塞（plug)構成之聯結器（coupler)。插座 與栓塞’係分別具有內藏閥體之閥機構，藉由將栓塞插入 插座使兩者之閥體頂接而使閥機構成爲開放狀態。如此則 ，例如於燃料電池側裝設插座之同時，於燃料盒側裝設栓 塞，藉由將栓塞插入插座’即可使燃料盒收容之甲醇燃料 供給至燃料電池（燃料收容部）。另外，將栓塞由插座拔; 出，則兩者之閥體分離使閥機構成爲關閉狀態，可抑制甲 醇燃料之不必要流出。 此種插座具有：筒狀之插座本體，其具有使栓塞插入 之開口部；及閥本體’被配置於其內部，作爲閥體。例如 插座本體，其由軸方向之大略中心位置至後端部（開口部 之相反側之端部）爲止之部分，係被設爲閥室；於該大略 中心位置被形成導孔用於插入閥本體。閥本體，係具備： 閥頭部，及較形成於其兩端之該閥桿爲小徑的閥柱部。開 口部側之閥柱部被插入導孔，閥頭部被配置於閥室。 另外，在插座本體之開口部側之內部設有：覆蓋前端 側閥柱部之外周部分而具有蛇腹形狀之大略圓筒形狀之橡 膠保持器。橡膠保持器爲，頂接於被插入之栓塞之前端部 之同時，配合該栓塞之插入收縮，最終在插座與栓塞之兩 者之閥機構成爲開放狀態時內部成爲甲醇燃料之流路。藉 由該橡膠保持器，在插座與栓塞之兩者之閥機構成爲開放 狀態之前可以確立流路，可以抑制不必要之甲醇燃料流出 -6- 201013081 外部’可構成安全性佳者（例如專利文獻3 )。 但是，上述構造之插座，開口部側之閥柱部，僅藉由 設於閥本體大略中間位置之導孔被支撐，對於來自徑方向 外側之負荷之機械強度變低。因此，栓塞被斜向插入插座 等來自徑方向外側之負荷被施加時，開口部側之閥柱部有 可能變形。閥柱部之變形會使閥機構無法適當動作，例如 連接栓塞時甲醇燃料無法適當被供給，或取出栓塞時甲醇 燃料之不必要流出等。 特別是，近年來，燃料電池或其使用之插座被要求小 型化，配置於其內部之閥本體亦被小型化，導致機械強度 降低、變形之可能性變高。另外，於開口部側之閥柱部之 外周部分設有橡膠保持器，該橡膠保持器，係由彈性材料 構成者，未必是將閥本體由外周予以支撐者，無法有效抑 制其之變形。 [專利文獻1]特許第3413111號說明書

本發明之燃料電池用插座，係使對燃料電池供給液體 燃料而噴出該液體燃料的燃料電池用栓塞可以裝/拆地被 插入使用者；其特徵爲具有：筒狀之插座本體，其被插入 該栓塞；閥體，設於該插座本體內；及滑動環，設於該閥 體之外周部分，配合栓塞之插入被頂接於該燃料噴出口之 外周部分而同時移動。 本發明之燃料電池用聯結器，其特徵爲具有：上述本 發明之燃料電池用插座；及可以裝/拆地被插入該燃料電

於收容供給給該燃料電池芯3之液體燃料的燃料收容部4 ，以及對該燃料收容部4供給液體燃料之燃料受容部5, 而本發明之燃料電池用插座（以下簡單稱爲插座）6係裝 -8- 201013081 設於燃料受容部5。另外，燃料電池1也可以構成不經由 燃料收容部4而由燃料受容部5直接對燃料電池芯3供給 液體燃料。 另一方面’盒2具有收容液體燃料的容器之盒本體7 ’而在其前端部分裝設有用於噴出收容於盒本體7之液體 燃料的燃料電池用栓塞8(以下簡單稱爲栓塞）。此種盒 2’係僅在對燃料電池1注入液體燃料時被連接者，係所 • 謂的衛星型（外部注入式）之盒。 盒本體7中收容有對應於燃料電池1之液體燃料，例 如屬直接甲醇型燃料電池（DMFC)時，即收容各種濃度 之甲醇水溶液或純甲醇等之甲醇燃料。另外，被收容於盒 本體7之液體燃料不一定限於甲醇燃料，也可以爲例如乙 醇水溶液或純乙醇等之乙醇燃料，丙醇水溶液或純丙醇等 之丙醇燃料，乙二醇水溶液或純乙二醇等之乙二醇燃料， 二甲醚，甲酸，或其他液體燃料。不管那一種，符合燃料 φ 電池1之液體燃料皆可收容。 本發明之燃料電池用聯結器（以下簡單稱爲聯結器） 9，係由此種插座6與栓塞8構成。插座6與栓塞8，係 分別具有閥機構者，在圖示之分離狀態時，彼等閥機構成 爲關閉狀態，液體燃料之流出被抑制。在栓塞8被插入插 座6的連接狀態時，彼等閥機構成爲開放狀態，液體燃料 之供給成爲可能。 圖2表示本發明之插座6，及使用其之聯結器9(分 離狀態）之縱斷面圖。另外，以下稱插座6與栓塞8之個 -9- 201013081 別對向之側爲前端側，彼等之相反側爲後端側予以說明。 亦即，關於插座6，圖中上側爲前端側，關於栓塞8，圖 中下側成爲前端側。 插座6也稱爲雌側聯結器，具有插座本體61;於其 內部沿軸方向配置之閥體、亦即閥本體62;及於插座本 體61內部，在閥本體62之前端側外周部分被設置的滑動 環63。 插座本體61，係具有：配置於前端側的略呈圓筒狀 之前端側筒部64，及被固定於其後端側的略呈圓筒狀之 後端側筒部6 5。 前端側筒部64，於前端側具有插入栓塞8之開口部 ，於後端部64a之軸心部分具有使閥本體62被插入用之 導孔64b。在前端側筒部64之前端側設置沿軸方向被形 成之溝部、亦即鍵溝64k。該鍵溝64k，係被嵌入在栓塞 8之側面部沿軸方向被形成之鍵部81k，作爲燃料辨識手 段被使用。 後端側筒部65，係於前端側具有開口部，該開口部 被連接於前端側筒部64之後端部64a。於後端側筒部65 之後端部，於軸心部分設有朝前端側突出之閥頂接部65a ，於其外周部分以特定間隔設置成爲液體燃料之流路的多 數流通孔65b。 閥本體62，係成爲構成閥機構之閥體者，具有：閥 頭部62b;構成較閥頭部62b爲小徑，形成於閥部頭62b 之兩端的前端側閥柱部62a及後端側閥柱部62c。 -10- 201013081 前端側閥柱部62a，係可移動地被插入導孔64b，延 伸至前端側筒部64之內部。於前端側閥柱部62a之側面 部，形成沿軸方向而成爲液體燃料之流路的溝部62d。如 此則’可使液體燃料有效通過導孔64b。另外，閥頭部 62b及後端側閥柱部62c，係可移動地被配置於後端側筒 部65之內部。 於後端側筒部65之內部，於閥頭部62b之前端側被 φ 配置〇環66之同時，於後端側被配置壓縮彈簧等之彈性 體67，用於將閥本體62按壓至前端側。彈性體67，係於 例如閥頭部62b之後端側，以包圍後端側閥柱部62c及閥 頂接部65a的方式被配置。 於分離狀態，藉由彈性體67使閥本體62 (閥頭部 62b )被按壓至前端側，如此則，導孔64b被0環66及閥 頭部6 2b堵住，閥機構被設爲關閉狀態，插座6之液體燃 料之流出（逆流）被抑制。由於此一觀點，而將0環66 或閥頭部62b之外徑設爲大於導孔64b之內徑。 另外，於連接狀態，閥本體62往後端側移動，使導 孔64b呈開放，閥機構成爲開放狀態。如此則，由栓塞8 噴出之液體燃料可以經由導孔64b通過後端側。 滑動環63，係大略圓筒形狀者，於前端側筒部64之 內部，以包圍前端側閥柱部62a之前端側外周部分的方式 被配置。滑動環63，係可對前端側筒部64移動之同時， 亦可對前端側閥柱部62a移動而構成。 滑動環63，被插入栓塞8時係頂接於其前端側形成 -11 - 201013081 之燃料噴出口 81e之外周部分之同時朝後端側移動者，將 該燃料噴出口 81e之外周部分密封，而內部成爲液體燃料 之流路者。另外，滑動環63，例如圖3所示栓塞8被斜 向插入時，可保護前端側閥柱部62a，抑制其變形者。 此種滑動環63，主要由：例如前端側環部63a ,及設 於其後端側，較其爲大徑的後端側環部63b構成（亦參照 圖4 )。 前端側環部63 a，在栓塞8之插入時，係被嵌入栓塞 8之密封凹部81d，而將燃料噴出口 81e之外周部分予以 密封者。於前端側環部63a之前端側，欲更有效密封燃料 噴出口 81e之外周部分時，較好是例如於前端側配置凸狀 之前端側密封構件63c。前端側密封構件63c，較好是和 前端側環部63a之前端部一體成形，另外，就抑制由前端 側環部63a之脫落観點而言，雖未特別圖示，較好是使一 部分被插入前端側環部63a之前端面設置的溝部等凹部而 予以一體成形。 作爲前端側環部63 a，較好是使用耐甲醇性較佳之彈 性材料，作爲熱可塑性彈性體，可使用例如苯乙烯系列彈 性體（TPS )、烯系列彈性體（TPO )、聚酯系列彈性體 (TPEE )、聚醯胺系列彈性體（PEBAX )、聚矽氧烷系 列彈性體、氟系列彈性體等，作爲橡膠材料可使用例如乙 烯—丙烯—二烯烴橡膠（EPDM )、丙烯腈丁二稀橡膠（ NBR )、氫腈橡膠（HNBR)、氟橡膠（FKM)、聚矽氧 烷橡膠（VMQ)、氟聚矽氧烷橡膠（FVMQ)等。彼等之 201013081 中’特別是，考慮耐甲醇性，而較好是使用乙烯-丙烯― 二烯烴橡膠（EPDM) '氟橡膠（FKM)、聚矽氧烷橡膠 (VMQ)。 前端側環部6 3 a及形成於其前端側之前端側密封構件 63c之外徑，較好是以可裝/拆地嵌入密封凹部81d的程 度’設爲和密封凹部81d之內徑大略同樣。另外，前端側 環部63a與前端側密封構件63c之合起來之軸方向之長度 ’較好是使前端側環部63a與前端側密封構件63c插入密 封凹部81d，藉由前端側密封構件63c能有效密封燃料噴 出口 81e之外周部分的方式，設爲和密封凹部8id之深度 大略同樣或其以上。其中，前端側環部63 a與前端側密封 構件63c之合起來之軸方向之長度，係指自前端側環部 63a與後端側環部63b之外側部分之段部，至前端側密封 構件63 c之前端部爲止之沿軸方向之長度。另外，後端側 環部63b之外徑，較好是對前端側筒部64成爲可移動之 0 同時’使來自其與前端側筒部64之間之液體燃料之流處 盡量變少，而設爲和前端側筒部64之內徑大略同樣。 另外，前端側環部63 a及前端側密封構件63c之內徑 ’較好是對前端側閥柱部62a成爲可移動，而設爲和前端 側閥柱部62a之外徑大略同樣。另外，後端側環部63b之 內徑，至少需要對前端側閥柱部62a成爲可移動的程度， 內部被配置壓縮彈簧等彈性體69時，較好是設爲和彈性 體69之外徑大略同樣。 另外，滑動環63之沿軸方向之全體長度較好是設爲 -13- 201013081 ，在栓塞8完全插入插座6時，其前端部（於此爲前端側 密封構件63c之前端部）可頂接於栓塞8之燃料噴出口 81e之外周部分，而且後端部（後端側環部63 b之後端部 )可頂接於配置於後端部64a之前端側之Ο環71的程度 。藉由設爲此種長度，在栓塞8完全插入插座6時，栓塞 8之燃料噴出口 81e與第1閘極6之導孔64b可藉由滑動 環63予以連接，可抑制液體燃料之流出至外部。 於後端側環部63b之側面部，被形成例如環繞該側面 部一周之溝狀凹部63d，於該凹部63d配置0環等構成之 側面側密封構件68較好。通常，栓塞8被插入插座6時 ，滑動環63頂接於其後端側之Ο環71之前，插座6或栓 塞8之閥機構被設爲開放狀態，液體燃料由滑動環63與 0環71之間傳遞至滑動環63之側面部而流出外部之可能 性存在，因此，藉由在後端側環部63b之側面部配置側面 側密封構件68，可抑制上述液體燃料之流出，能構成更 具有安全性者。此種側面側密封構件68，較好是由例如 和前端側密封構件63c同樣之材料構成。 另外，亦可取代凹部63d與配置於其之側面側密封構 件68，已於後端側環部63b之側面部塗敷脂膏狀潤滑劑 ，藉此來密封側面側。此種潤滑劑，可使用由例如氟系列 潤滑劑、聚矽氧烷系列潤滑劑、烯系列潤滑劑之中選擇之 至少1種潤滑劑。 氟系列潤滑劑可使用例如羥基氟醚、全氟聚醚、三氟 化氯乙烯低聚合物等，聚矽氧烷系列潤滑劑可使用例如甲 -14- 201013081 基聚矽氧烷油、甲基苯基聚矽氧烷油、甲基羥基二烯烴聚 矽氧烷油、或彼等之變性物等，烯系列潤滑劑可使用例如 聚乙烯、聚丙烯、乙烯一丙烯共聚合物、乙烯—丁烯共聚 合物、乙烯-辛烯共聚合物、聚丙烯-丁烯共聚合物、聚 丁烯、乙烯一丙烯酸酯共聚合物、乙烯-甲基丙烯酸酯共 聚合物、乙烯-丙烯酸共聚合物、乙烯_醋酸乙烯基共聚 合物、或彼等之變性物等。 ® 滑動環63，係藉由配置於其後端側之壓縮彈簧等彈 性體69等往前端側被按壓。於分離狀態，通常以可以有 效保護前端側閥柱部62a的方式，使滑動環63之前端部 與閥本體62之前端部成爲大略同樣位置而予以調整，滑 動環63之位置係藉由制動器機構予以調整。 制動器機構，係由：例如於前端側筒部64之側面部 朝軸方向延伸形成的孔部、亦即制動器承受部64s，及於 滑動環63之側面部朝徑方向外側突出形成，被插入制動 φ 器承受部64s的制動器63s構成。藉由調整制動器承受部 64s之軸方向之長度，可調整滑動環63之位置。 如上述說明之側面側密封構件68，爲能有效抑制來 自制動器承受部64s之液體燃料之流出’較好是配置成爲 較制動器承受部64s之後端部成爲更後端側。另外，圖中 ，側面側密封構件側面側密封構件68之斷面形狀雖爲圓 形，但亦可設爲V型或X型之斷面形狀而更提升密封性 〇 另外，於後端部64a之前端側，以包圍導孔64b之外 -15- 201013081 周部分的方式，而且連接狀態時頂接於滑動環63之後端 部的位置，設置〇環71。該〇環71’係於滑動環63移動 至後端側時，藉由滑動環63之後端部與後端部64a被按 壓，爲密封彼等之間而設置。 此種插座6之構成材料，除壓縮彈簧等彈性體67、 69或前端側密封構件63c、側面側密封構件68以外，通 常可使用非金屬材料例如聚丙烯（PP)、聚苯撐硫化物（ PPS )、高密度聚乙烯（HDPE)、聚苯乙烯（PS)等，另 外，亦可使用具有耐甲醇性之聚醚醚酮（PEEK )、液晶 聚合物（LCP)等之超級工程塑膠、或PET (聚對苯二甲 酸乙二醇酯）、PBT (聚對苯二甲酸丁二醇酯）、聚甲醛 (POM)等之泛用工程塑膠。 栓塞8係俗稱雄側聯結器者，具有：盒本體7被嵌入 的栓塞頭部81，配置於該栓塞頭部81內部的閥本體82， 及將栓塞頭部81由外側予以覆蓋而被固定於盒本體7的 按壓帽部83等。 栓塞頭部81具有：嵌入盒本體7的筒狀底座部81a ，以及設置於其前端側之更細徑的細徑部81b。底座部 81a之內竟被設爲和盒本體7之前端側外徑大略同樣尺寸 。另外，於細徑部81b之側面部設置朝軸方向延伸的凸部 、亦即鍵部81k，該鍵部81k係被嵌入插座6之鍵溝64k ’作爲燃料辨識手段被使用。細徑部81b之外徑，除形成 鍵部81k之部分以外，以例如可以裝/拆地被插入插座6 之前端側筒部64的程度，被設爲和前端側筒部64之內徑 -16- 201013081 大略同樣尺寸。 於細徑部8 1 b之軸心部分形成軸孔8 1 C，其成爲盒本 體7收容之液體燃料之流路之同時，被插入閥本體82 ( 前端側閥柱部82a)。軸孔81c之內徑，係以例如閥本體 82 (前端側閥柱部82a)成爲可移動的程度，被設爲和前 端側閥柱部82a之外徑大略同樣尺寸。 於細徑部81b之前端側，以凹陷前端面的方式形成密 封凹部81d，於密封凹部81d之底面之軸心部分形成連接 軸孔81c的燃料噴出口 81e。燃料噴出口 81e，係將收容 於盒本體7之液體燃料噴出的部分，密封凹部81d，係作 爲暫時收容部之功能，將燃料噴出口 81e噴出的液體燃料 之殘留物（附著物）收容，構成爲操作者不會接觸液體燃 料。另外，於該密封凹部81d，被插入滑動環63之前端 側環部63a及前端側密封構件63c，於燃料噴出口 81e之 外周部分觸接前端側密封構件63c。 於底座部81a之內側配置杯狀之閥保持器84。閥保 持器84，係用於界定閥室者，其前端側外緣部所形成之 凸緣部84a介由0環85，自後端側被盒本體7按壓而被 固定於底座部81a。另外，於閥保持器84之後端部，形 成成爲液體燃料之流路的連通孔84b。 閥本體82，係成爲構成閥機構之閥體者，具有閥頭 部82b，設爲較閥頭部82b小徑’形成於閥頭部82b之兩端 的前端側閥柱部82a及後端側閥柱部82c。另外，於前端 側閥柱部8 2 a及後端側閥柱部8 2 c，被形成沿軸心部分成 -17- 201013081 爲流路的溝部82d。 前端側閥柱部82a，係可移動地被插入軸孔81c，閥 頭部82b及後端側閥柱部82c，係可移動地被配置於閥保 持器84內部。於閥頭部82b之前端側，以包圍前端側閥 柱部8 2a之外周部分的方式被配置〇環86，於閥頭部8 2b 之後端側被配置壓縮彈簧等彈性體87。 於分離狀態，藉由彈性體87按壓閥頭部82b，藉由 軸孔8 1 c之後端側與0環8 6使軸孔8 1 c之後端側被堵住 ，閥機構被設爲關閉狀態，噴嘴8 (燃料噴出口 81e)之 液體燃料之流出被抑制。 另外，於連接狀態，藉由Ο環86與閥本體82朝後端 側移動，使軸孔8 1 c之被開放，閥機構成爲開放狀態。如 此則，收容於盒本體7之液體燃料經由軸孔81c由燃料噴 出口 81e被噴出。 關於栓塞8之構成材料，和插座6同樣，除0環85 、86或壓縮彈簧等彈性體87以外，通常可使用非金屬材 料例如聚丙烯（PP)、聚苯撐硫化物（PPS)、高密度聚 乙烯（HDPE)、聚苯乙烯（PS)等，另外，亦可使用具 有耐甲醇性之聚醚醚酮（PEEK)、液晶聚合物（LCP )等 之超級工程塑膠、或PET (聚對苯二甲酸乙二醇酯）、 PBT (聚對苯二甲酸丁二醇酯）、聚甲醛（POM )等之泛 用工程塑膠。 插座6及使用其之聯結器9，係如下被使用。圖5(a )〜（d)表示聯結器9之連接工程，圖5(a)表示分離 -18- 201013081 狀態，以下依序表示連接工程。另外，於圖5(a)〜（d )之各部之符號爲共通，因此僅5(a)附加符號，以外 則省略符號。 首先，由分離狀態（圖5(a))將栓塞8插入插座6 ，則滑動環63之前端側密封構件63c被插入栓塞8之密 封凹部81d，該前端側密封構件63c之前端部頂接於燃料 噴出口 81e之外周部分成爲密封狀態。閥本體62之前端 • 部頂接於閥本體82之前端部。 之後，插入栓塞8時，配合栓塞8之插入使滑動環 63被往後端側下壓之同時，閥本體62被往後端側下壓， 插座6之閥機構被設爲開放狀態（圖5(b))。此時， 僅閥本體62被往後端側下壓，閥本體82未被往後端側下 _ 壓，栓塞8之閥機構乃保持關閉狀態。 其中，插座6之閥機構先行設爲開放狀態之理由在於 ，欲確保安全性使使液體燃料被供給側之閥機構先行設爲 φ 開放狀態乃有效者。於此，插座6之閥機構先行設爲開放 狀態，因此，相較於插座6中之按壓閥本體62引起之彈 性體67之反彈力量，將栓塞8中之按壓閥本體82引起之 彈性體87之反彈力量設爲較大。 另外，插座6之閥機構先行設爲開放狀態時，液體燃 料由後端側筒部65至前端側筒部64之逆流雖存在，但栓 塞8之燃料噴出口 81e之外周部分與滑動環63之前端部 之間成爲密封狀態，另外，前端側筒部64之內面與滑動 環63之側面部之間藉由側面側密封構件68而成爲密封狀 -19- 201013081 態，因此，逆流之液體燃料被保存於前端側筒部64與滑 動環63所形成之空間，不會流出外部。 再進一步插入栓塞8時，閥本體62之後端部會頂接 於閥頂接部65a (圖5(c))。閥本體62，係藉由後端 部之頂接於閥頂接部65a，之後無法再往後端側移動。又 ，滑動環63，於此時點完全未往後端側以動，因此，之 後亦無法往後端側移動。 於此狀態下插入栓塞8時，閥本體82被閥本體62反 押而無法更進一步插入插座6，僅栓塞頭部81 (細徑部 81b)被插入插座6。此時，於栓塞8之內部，對於栓塞 頭部81，閥本體82成爲往後端側移動，閥機構成爲開放 狀態。栓塞8之閥機構成爲開放狀態時，亦和插座6之閥 機構成爲開放狀態時同樣，噴出之液體燃料被保存於前端 側筒部64與滑動環63所形成之空間，不會流出外部。 之後，滑動環63之後端部頂接於Ο環71，在栓塞8 之插入成爲困難之時點，被設爲最終之栓塞8之插入完了 者（圖5(d)、圖6)。此時，第1閘極6及栓塞8之各 個閥機構成爲開放狀態，因此液體燃料由栓塞8之燃料噴 出口 81e被噴出，噴出之液體燃料經由插座6之滑動環 63、導孔64b被導入後端側筒部65。被導入後端側筒部 65之液體燃料，係由設於其後端部之流通孔65 b被導入 燃料電池1之接燃料受容部5。 如上述說明，栓塞8之插入插座6時，插入開始至插 入終了爲止之間，於栓塞8之燃料噴出口 81e之外周部分 -20- 201013081 被頂接滑動環63而成爲密封狀態，因此液體燃料之流出 外部會被抑制。另外，該滑動環63，係以包圍插座6之 閥本體62 (前端側閥柱部6 2a)外周部分的方式被配置， 即使栓塞8被斜向插入時亦可有效保護閥本體62» 另外，由插座6拔出栓塞8時，係進行和上述逆向之 動作。首先，由插座6拔出栓塞8時，僅栓塞頭部81( 細徑部81b)被由插座6拔出，閥本體82乃停留於原來 _ 位置。此時，滑動環63係配合栓塞8之拔出而往前端側 移動。 之後，栓塞8之閥機構成爲關閉狀態時，之後和栓塞 頭部81同樣地閥本體82成爲被由插座6拔出。如此則， 目前爲止被限制移動的閥本體62亦配合閥本體82之拔出 而往前端側移動（圖5(b) 、（c))。 插座6之閥機構成爲關閉狀態之後，閥本體62之前 端部與閥本體82之前端部呈分離狀態，栓塞頭部81與滑 φ 動環63亦呈分離狀態，最後，栓塞8被由插座6拔出（ 圖 5(a)、圖 2)。 如上述說明，栓塞8被由插座6拔出時，拔出開始至 拔出終了爲止之間，於栓塞8之燃料噴出口 81e之外周部 分被頂接滑動環63而成爲密封狀態，因此液體燃料之流 出外部會被抑制。 關於聯結器9，例如圖7所示，較好是於鍵溝64k之 後端側形成沿軸方向之溝部、亦即縫隙部64r。該縫隙部 64r之後端部’較好是設爲較制動器承受部64s之後端部 -21 - 201013081 大略同程度之位置或較爲前端側。藉由縫隙部64r之形成 ，即使栓塞8被斜向插入時，藉由前端側筒部64朝徑向 外側之擴展來緩和對各部之負荷，使損傷被抑制。另外， 縫隙部64γ被形成之位置，較好是上述之鍵溝64k之後端 側，但並不限定於此。 另外，於細徑部8 1 b之側面部，較好是設置朝徑向外 側突出之卡合凸部81g之同時，於前端側筒部64在連接 狀態時在該卡合凸部81g之對向位置設置卡合孔部64g。 藉由一對卡合部之設置，操作者將燃料電池用栓塞8插入 插座6時可獲得適當之裝設感，亦可判斷插入位置（深度 )是否適當。該卡合凸部81g，被形成爲例如越往前端側 或後端側其高度變爲越低，如此則，栓塞8之插入/拔出 變爲容易而較好是。 以上說明本發明之插座6及使用其之聯結器9之一力 ，但本發明不限定於此，例如可適當變更插座6之插座本 體61或滑動環63之構造。 圖8表示本發明之插座6之變形例之斷面圖。圖8(

被嵌入前端側筒部64之後端側筒部65，係具有例如 被嵌入前端側筒部64之小徑部，及頂接於前端側筒部64 之後端部的大徑部。小徑部，係被延伸到達閥本體62之 閥頭部62b之前端側，於該部分被封閉之同時，於該封閉 部分之軸心部分，設置用於插入前端側閥柱部62a的導孔 65c。大徑部，係自前端側筒部64之後端部朝後端側被延 伸，於後端部設置開口。 被嵌入後端側筒部65之底部72，係具有例如被嵌入 後端側筒部65之小徑部，及頂接於後端側筒部65之後端 部的大徑部。小徑部，係嵌入後端側筒部65之大徑部之 同時，被延伸至頂接於該小徑部之後端側，於前端部設有 開口。大徑部，基本上被封閉，於軸心部分設置朝前端側 突出的閥頂接部72a，於閥頂接部72a之外周部分，隔開 特定間隔設置成爲液體燃料之流路的多數流通孔7 2b。 另外，於插座6，係利用前端側筒部64之軸方向之 內徑差（軸方向之段差）構成制動器機構。亦即，利用滑 動環63之後端側環部63b，作爲構成制動器機構之制動 器63s，利用前端側筒部64之軸方向之內徑差，作爲制 動器承受部64s。 具體言之爲，於前端側筒部64之前端側，設置較滑 動環63之後端側環部63b爲小徑的窄徑部64c，於其後 端側，在後端側環部63b之可移動範圍內，設置和後端側 環部63b大略同樣內徑之寬徑部64d。 -23-

特別是，在滑動環63之後端側被形成之空間部、亦即在 前端側筒部64與插入筒部65d之間之部分，可以抑制液 體燃料之侵入，結果，可以抑制液體燃料殘留於該部分》 亦即，結束燃料之供給，由圖9(b)所示連接狀態 拔出栓塞8時，隨栓塞8之拔出之同時，滑動環63往前 端側移動，於該滑動環63之後端側形成空間部。另外， 於拔出栓塞8之過程，插座6或栓塞8之閥機構未完全成 爲關閉狀態，因此液體燃料由栓塞8噴出、或液體燃料由 -25- 201013081 插座6逆流之情況存在。 依據於滑動環63之內側進行密封者，於拔出栓塞8 之過程，即使發生液體燃料由栓塞8噴出、或液體燃料由 插座6逆流之情況，彼等燃料可以保存於滑動環63之內 部，可以抑制往後端側之侵入。 因此，於滑動環63之內側進行密封的插座6，可以 有效利用液體燃料之同時，可以提升安全性。另外，於該 插座6，在滑動環63或插入筒部65d之實質外側，在被 密封部分之外側配置彈性體69，因此可以抑制液體燃料 之接觸彈性體69，可抑制其之腐蝕。 上述係說明於滑動環63之內側進行插座本體61與滑 動環63之密封而成之插座6，但被插入滑動環63之插入 筒部未必如圖9所示設於後端側筒部65，亦可以如圖2 所示，針對前端側筒部64之後端側之一部分被殘留堵塞 者，設置於該前端側筒部64之後端側部分。

Description of the invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a socket for a fuel cell, And fuel cell couplings and fuel cells using the same. [Prior Art] In recent years, It is a portable electronic device such as a notebook computer or mobile phone 0 that can be used for a long time without charging. People are trying to use fuel cells to power these portable electronic devices. The fuel cell can generate electricity by supplying fuel and air. As long as the fuel is replenished, it can generate electricity for a long time. therefore, As long as the fuel cell can be reduced, It is a very beneficial system for powering electronic devices. especially, Direct methanol fuel cell (DMFC: using methanol fuel with high energy density) Direct methanol fuel cell) can be miniaturized, And the fuel is easy to handle, Therefore, it is considered to be a power source for the portable machine φ. The known DMFC liquid fuel supply method includes an active mode such as a gas supply type and a liquid supply type. Alternatively, it is a passive method in which the liquid fuel in the fuel tank is vaporized inside the battery and supplied to the internal vaporization type of the fuel electrode. among them, The passive approach facilitates miniaturization of the DMFC. In the internal gasification type passive DMFC, The liquid fuel in the fuel storage portion is vaporized through a fuel impregnation layer or a fuel gasification layer. The fuel is supplied to the fuel electrode (see, for example, Patent Documents 1 to 2). For the supply of methanol fuel in such a fuel accommodating portion, for example, a satellite type (external injection type) fuel -5 - 201013081 box is used. When using a fuel cartridge to supply methanol fuel, A coupler composed of a socket and a plug is usually used. The socket and the plug's respectively have a valve mechanism with a built-in valve body. The valve mechanism is opened by inserting the plug into the socket to abut the valve bodies of the two. So, For example, while installing a socket on the fuel cell side, Install a plug on the fuel tank side, The methanol fuel contained in the fuel cartridge can be supplied to the fuel cell (fuel storage portion) by inserting the plug into the socket. In addition, Pull the plug out of the socket; Out, Then the valve body separation of the two causes the valve mechanism to be closed. It can inhibit the unnecessary outflow of methanol fuel. This socket has: a cylindrical socket body, It has an opening for inserting the plug; And the valve body 'is disposed inside thereof As a valve body. Such as the socket body, a portion from a substantially central position in the axial direction to a rear end portion (end portion on the opposite side of the opening portion), Is set as a valve chamber; A guide hole is formed at the approximate center position for insertion into the valve body. Valve body, The system has: Valve head, And the valve stem formed on the both ends of the valve stem is a small diameter. The spool portion on the opening side is inserted into the guide hole. The valve head is disposed in the valve chamber. In addition, Inside the opening side of the socket body is provided: A substantially cylindrical rubber retainer that covers the outer peripheral portion of the front side valve stem portion and has a bellows shape. The rubber retainer is, Adjacent to the end of the inserted plug, Cooperating with the insertion and contraction of the plug, Finally, when the valve mechanism of both the socket and the plug is in an open state, the inside becomes a flow path of methanol fuel. By the rubber retainer, The flow path can be established before the valve mechanism of the socket and the plug is opened. It is possible to suppress unnecessary methanol fuel outflow -6- 201013081 External 'can constitute a safety person (for example, Patent Document 3). but, The socket of the above construction, The spool portion on the opening side, Only supported by a guide hole provided at a substantially intermediate position of the valve body, The mechanical strength from the load on the outer side in the radial direction becomes low. therefore, When the plug is inserted obliquely into the socket, when a load from the outside of the radial direction is applied, The spool portion on the opening side may be deformed. The deformation of the spool will prevent the valve mechanism from functioning properly. For example, methanol fuel cannot be properly supplied when the plug is connected. Or unnecessary discharge of methanol fuel when removing the plug. especially, In recent years, The fuel cell or the socket used therefor is required to be miniaturized. The valve body disposed inside is also miniaturized. Resulting in a decrease in mechanical strength, The possibility of deformation becomes higher. In addition, A rubber retainer is provided on an outer peripheral portion of the spool portion on the opening side. The rubber retainer, Made up of elastic materials, It is not necessarily the case that the valve body is supported by the outer circumference. It is not possible to effectively suppress its deformation. [Patent Document 1] Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. 2004-31. The object of the invention is to provide The deformation of the valve body caused by the oblique insertion of the plug can be suppressed, A reliable fuel cell socket.

Socket 6 and plug 8, Departments have valve mechanisms, In the separated state of the figure, Their valves are closed, The outflow of liquid fuel is suppressed. When the plug 8 is inserted into the connection state of the socket 6, Their valve mechanisms are open, The supply of liquid fuels is possible. Figure 2 shows the socket 6 of the present invention, And a longitudinal section view of the coupling 9 (separated state) using the same. In addition, Hereinafter, the socket 6 and the plug 8 are -9-201013081, and the opposite side is the front end side. The opposite side of them is explained on the back side. that is, About socket 6, The upper side of the figure is the front side. About embolization 8, The lower side of the figure becomes the front end side. The socket 6 is also referred to as a female side coupling. Having a socket body 61; a valve body disposed along the axis of the shaft, That is, the valve body 62; Inside the socket body 61, A slide ring 63 is provided at the outer peripheral portion of the end side of the valve body 62. Socket body 61, Has: a slightly cylindrical front end side cylindrical portion 64 disposed on the front end side, And a slightly cylindrical rear end side tubular portion 65 that is fixed to the rear end side thereof. Front end side tubular portion 64, An opening portion for inserting the plug 8 on the front end side, The axial center portion of the rear end portion 64a has a guide hole 64b for inserting the valve body 62. A groove portion formed along the axial direction is provided on the front end side of the front end side tubular portion 64, That is, the key groove 64k.

On the side of the front end side spool portion 62a, A groove portion 62d that serves as a flow path of the liquid fuel in the axial direction is formed. Thus, the liquid fuel can be effectively passed through the pilot hole 64b. In addition, a valve head portion 62b and a rear end side spool portion 62c, It is movably disposed inside the rear end side cylindrical portion 65.

Elastomer 67, For example, on the rear side of the valve head 62b, It is disposed so as to surround the rear end side spool portion 62c and the valve top portion 65a. In the separated state, The valve body 62 (the valve head 62b) is pressed to the front end side by the elastic body 67, So, The guide hole 64b is blocked by the 0 ring 66 and the valve head 6 2b. The valve mechanism is set to the off state, The outflow (countercurrent) of the liquid fuel of the socket 6 is suppressed. Because of this point of view, The outer diameter of the 0 ring 66 or the valve head 62b is set to be larger than the inner diameter of the guide hole 64b. In addition, In the connected state, The valve body 62 moves toward the rear end side, Opening the guide hole 64b, The valve mechanism is open.

Socket 6 and a coupling 9 using the same, It is used as follows. 5(a) to (d) show the connection work of the coupler 9, Figure 5 (a) shows the state of separation -18- 201013081, The following shows the connection project in order. In addition, The symbols of the parts of Figures 5(a) to (d) are common. So only 5 (a) additional symbols, Otherwise, the symbol is omitted. First of all, Inserting the plug 8 into the socket 6 from the separated state (Fig. 5(a)), Then, the front end side sealing member 63c of the slide ring 63 is inserted into the sealing recess 81d of the plug 8, The front end portion of the front end side sealing member 63c is in a sealed state in contact with the outer peripheral portion of the fuel discharge port 81e. The front end of the valve body 62 is abutted against the front end of the valve body 82. after that, When inserting the plug 8, With the insertion of the plug 8, the sliding ring 63 is pressed down toward the rear end side, The valve body 62 is pressed down toward the rear end side, The valve mechanism of the socket 6 is set to an open state (Fig. 5(b)). at this time, Only the valve body 62 is pressed down toward the rear end side, The valve body 82 is not pressed toward the rear end side, The valve mechanism of the plug 8 is kept closed. among them, The reason why the valve mechanism of the socket 6 is first set to the open state is that It is effective to ensure safety by setting the valve mechanism on the supply side of the liquid fuel to the φ open state. herein, The valve mechanism of the socket 6 is first set to an open state. therefore, Compared with the rebounding force of the elastic body 67 caused by the pressing valve body 62 in the socket 6, The rebounding force of the elastic body 87 caused by the pressing valve body 82 in the plug 8 is set to be large. In addition, When the valve mechanism of the socket 6 is first set to the open state, Although the backflow of the liquid fuel from the rear end side cylindrical portion 65 to the front end side cylindrical portion 64 exists, However, the outer peripheral portion of the fuel discharge port 81e of the plug 8 and the front end portion of the slip ring 63 are sealed. In addition, The inner surface of the front end side tubular portion 64 and the side surface portion of the slide ring 63 are sealed by the side surface side sealing member 68. -19-201013081, therefore, The counter-current liquid fuel is stored in a space formed by the front end side tubular portion 64 and the sliding ring 63. Will not flow out of the outside. When the plug 8 is further inserted, The rear end of the valve body 62 is abutted against the valve abutment 65a (Fig. 5(c)). Valve body 62, By the top end of the valve portion being connected to the valve top portion 65a, Then you can no longer move to the back end side. Again, Slip ring 63, At this point, the point is not moved to the back end side. therefore, It is also impossible to move to the rear side. When the plug 8 is inserted in this state, The valve body 82 is reversed by the valve body 62 and cannot be further inserted into the socket 6, Only the plug head 81 (the small diameter portion 81b) is inserted into the socket 6. at this time, Inside the plug 8, For the plug head 81, The valve body 82 is moved toward the rear end side. The valve mechanism is open. When the valve mechanism of the plug 8 is opened, Also, when the valve mechanism of the socket 6 is in an open state, The ejected liquid fuel is stored in a space formed by the front end side tubular portion 64 and the slip ring 63. Will not flow out of the outside. after that, The rear end of the slip ring 63 is abutted against the ankle ring 71. When the insertion of the plug 8 becomes difficult, It is set as the final plug 8 is inserted (Fig. 5(d), Figure 6). at this time, The valve mechanisms of the first gate 6 and the plug 8 are opened. Therefore, the liquid fuel is ejected from the fuel discharge port 81e of the plug 8. The ejected liquid fuel passes through the slip ring 63 of the socket 6, The guide hole 64b is introduced into the rear end side tubular portion 65. The liquid fuel introduced into the rear end side tubular portion 65, The fuel receiving portion 5 of the fuel cell 1 is introduced into the flow hole 65b provided at the rear end portion thereof. As explained above, When the plug 8 is inserted into the socket 6, Between the insertion start and the end of the insertion, The outer peripheral portion -20-201013081 of the fuel discharge port 81e of the plug 8 is connected to the slip ring 63 to be sealed. Therefore, the outflow of liquid fuel is suppressed outside. In addition, The slip ring 63, It is disposed so as to surround the outer peripheral portion of the valve body 62 (the front end side spool portion 62 2a) of the socket 6, The valve body 62 can be effectively protected even when the plug 8 is inserted obliquely. When the plug 8 is pulled out by the socket 6, It performs the reverse action described above. First of all, When the plug 8 is pulled out by the socket 6, Only the plug head 81 (the small diameter portion 81b) is pulled out by the socket 6, The valve body 82 is in the original _ position. at this time, The slide ring 63 is moved toward the front end side in accordance with the pulling out of the plug 8. after that, When the valve mechanism of the plug 8 is closed, Thereafter, the valve body 82 is pulled out of the socket 6 in the same manner as the plug head 81. So, The valve body 62 that has been restricted to move so far is also moved toward the front end side in accordance with the pulling out of the valve body 82 (Fig. 5(b), (c)). After the valve mechanism of the socket 6 is turned off, The front end of the valve body 62 is separated from the front end of the valve body 82, The plug head 81 and the sliding φ moving ring 63 are also separated. At last, The plug 8 is pulled out of the socket 6 (Fig. 5(a), figure 2). As explained above, When the plug 8 is pulled out by the socket 6, Between the start of the pullout and the end of the pullout, The outer peripheral portion of the fuel discharge port 81e of the plug 8 is brought into contact with the slip ring 63 to be in a sealed state. Therefore, the flow of liquid fuel to the outside is suppressed. Regarding the coupling 9, For example, as shown in Figure 7, Preferably, a groove portion along the axial direction is formed on the rear end side of the key groove 64k, That is, the slit portion 64r. The end portion ′ after the slit portion 64r is preferably set to a position slightly larger than the end portion -21 - 201013081 of the brake receiving portion 64s or a relatively front end side. By the formation of the slit portion 64r, Even if the plug 8 is inserted obliquely, The load on the respective portions is alleviated by the expansion of the front end side tubular portion 64 toward the radially outer side. The damage is suppressed. In addition, a position at which the slit portion 64γ is formed, Preferably, it is the rear side of the above-mentioned key groove 64k, However, it is not limited to this. In addition, On the side portion of the small diameter portion 8 1 b, It is preferable to provide the engaging convex portion 81g that protrudes toward the radially outer side, When the distal end side tubular portion 64 is in the connected state, the engaging hole portion 64g is provided at the opposing position of the engaging convex portion 81g. With the setting of a pair of engaging parts, When the operator inserts the fuel cell plug 8 into the socket 6, an appropriate mounting feeling can be obtained. It is also possible to judge whether the insertion position (depth) is appropriate. The engaging convex portion 81g, It is formed such that the height becomes lower toward the front end side or the rear end side, for example. So, The insertion/extraction of the plug 8 becomes easy and preferable. The above describes the power of the socket 6 of the present invention and the coupler 9 using the same, However, the present invention is not limited to this. For example, the configuration of the socket body 61 or the slide ring 63 of the socket 6 can be appropriately changed. Fig. 8 is a cross-sectional view showing a modification of the socket 6 of the present invention. Figure 8(a) is a cross-sectional view showing the socket 6 when the coupler 9 is in a separated state. Fig. 8(b) is a cross-sectional view showing the socket 6 when the coupler 9 is in a connected state (the plug 8 is not shown). As shown in Figure 8 (a), The socket body 61. For example, it is also possible to embed the rear end side cylindrical portion 65 or the bottom portion 72 in order from the end portion of the front end side cylindrical portion 64. The front end side cylindrical portion 64 of the socket body 61, For example, if there are openings at both ends, It is configured to cover the size from the front end to the rear end of the valve body 62 by -22-201013081.

The falling off of the side tubular portion 64 is free to move the sliding ring 63. The formation range of the narrow diameter portion 64c or the wide diameter portion 64d of the distal end side tubular portion 64 is not necessarily limited. However, based on the front end of the effective protection valve body 62, Usually in the separated state of the coupler 9 to the front end of the valve body 62, It is preferable to make the front end portion of the slide ring 63 substantially the same position. According to this socket 6, For the front end side tubular portion 64, The socket body 61 can be easily manufactured by embedding the rear end side cylindrical portion 65 or the bottom portion 72' from the rear end side. In addition, At the same time as the manufacture of the socket body 61, The slip ring 63 or the valve body 62 can be assembled, Can greatly improve manufacturability. In addition, The end ring portion 63b after the slip ring 63 is used as the stopper 63s, The narrow diameter portion 64c or the wide diameter portion 64d provided inside the distal end side tubular portion 64 is used as the brake receiving portion 64s. So, For example, when the movement of the slide ring 63 toward the front end side is restricted, The end portion of the guide hole 64b can be topped over the entire circumference of the end portion after the narrow diameter portion 64c, Can be stronger, The stability restricts the movement of the slide ring 63 toward the front end side.
