200306039 (1) 玖、發明說明 【發明所屬之技術領域】 本發明是關於使用於資訊終端機器或電腦關連機器等 的電子機器之同軸連接器用接點及具備該接點的同軸連接 器。 【先前技術】 使用於資訊終端機器或電腦關連機器等的電子機器之 同軸電纜，是由外周側至中心部以外皮、密封導體、絕緣 體及中心導體的順序設置這些構件，且接地電位的密封導 體位在傳送接收資料訊號的中心導體的周圍。因此，通常 、同軸電纜是將其端部作成連接器，來使得能夠簡單地在 電子基板的訊號側與接地側連接中心導體與密封導體。 在將同軸電纜的端部作成連接器的情況時，中心導體 、絕緣體及密封導體分別露出地被切斷。然後，同軸電纜 的中心導體一邊抵接於同軸連接器用接點的平坦狀結線部 一邊被錫焊。當在進行錫焊時，液體狀的銲錫流動於結線 部上。因此，當錫焊量多時，銲錫由結線部流出，泛迴進 入到形成在結線部的左右兩側的接觸部，造成彈性（品質 )降低。特別是在銲錫迂迴進入到接觸部的內側的情況時 ，不僅造成彈性降低，也會造成電性接觸的不穩定化。 因此，在例如日本特開200 1 -43 93 9號公報，揭示著 :在中心導體的軸心方向之結線部的前端部與後端部分別 形成壁部，使中心導體位於這些壁部之間的結構者。若根 (2) (2)200306039 據此結構的話，對中心導體的結線部之錫焊動作是在壁部 間進行。因此，由於兩端部的壁部會發揮遮斷銲錫流出的 功能，故能防止錫焊朝接觸部流出。 但，在上述的以往的結構，無法充分地防止銲錫朝接 觸部流出。即，如上所述，即使在結線部的前端部及後端 部設置壁部’能阻止銲錫朝前後方向流出，也無法阻止銲 錫朝左右方向流出。又，由於在結線部的左右兩側形成接 觸部，故由結線部上的錫焊位置至接觸部的距離極小。因 此，即使例如錫焊量較通常的使用量稍許變多，朝左右方 向流動的銲錫會流動至接觸部，使得接觸部之彈性降低。 此結果，對於進行錫焊操作者造成過大的負擔，並且易使 成品性及生產性降低。 因此，本發明的目的是在於：提供能夠充分地防止銲 錫朝接觸部流出的同軸連接器用接點及具備該接點的同軸 連接器。 【發明內容】 發明揭示 本發明之同軸連接器用接點之特徵是在於：具有：供 同軸電纜的中心導體抵接，且利用銲錫來結線的結線部； 與在由則述結線部朝則述中心導體的軸心方向偏移的部位 ，呈左右對稱地垂下形成，且利用具有彈性在彈推狀態下 嵌合於對方側連接器的接觸部。 在於上述結構，當將中心導體錫焊於結線部時，熔融 (3) (3)200306039 狀態的銲錫朝結線部的外側流動。此時’由於從結線部朝 中心導體的軸心方向偏移的部位形成接觸部，故由結線部 上的錫焊位置至接觸部爲止的距離較長。因此’即使例如 錫焊量較通常的使用量稍許變多’或在受到在其他的錫焊 條件產生參差不齊的情事，銲錫在寬廣的範圍流動的情況 下，銲錫也不易流出至接觸部。藉此，能夠減輕進行錫焊 的操作者的負擔，並且能夠提高成品率及生產性。 又，本發明的同軸連接器用接點的特徵是在於：在前 述結線部之挾持前述中心導體的兩端部形成用來阻止銲錫 流動的防止流動壁。 若根據上述結構的話，由於結線部之挾持中心導體的 兩端部形成由進行錫焊位置最近的位置，故流動於結線部 的銲錫是最初到達結線部的兩端部，但，能利用兩端部的 防止流動部阻止了銲錫的流動，使得可防止錫焊由兩端部 行進到接觸部。其結果，能夠做成銲錫更不易流出至接觸 部。 又，本發明的同軸連接器用接點的特徵爲：具有：設 在前述中心導體的前端部側，形成可由兩側支承該中心導 體的側面之前端側定位部；及設在前述中心導體的根部側 ，形成可由兩側支承該中心導體的側面’並且形成抵接於 覆蓋該中心導體的介電質的端面之後端側定位部。 若根據上述結構的話，當同軸電纜的中心導體抵接於 結線部時，可利用以前端側定位部與後端側定位部於左右 方向限制該中心導體的前端部與根部的位置，來使得中心 -8 - (4)200306039 導體 中心 果， 減低 止了 能夠 定位 上之 【實 連接 利用 等的 同軸 抵接 結構 23 - 於用 成平 的全體精準度良好地定位在結線部的預定位置。 又，利用後端側定位部抵接於介電質的端面，可使得 導體也正確地定位於軸心方向也就是前後方向。此結 能夠減低每個製品的中心導體的位置的偏移，而能夠 品質的參差不齊。又，能夠在錫焊中心導體時，更防 銲錫由結線部流出至接觸部所引起之品質降低，並且 不須使用特別的外部裝置而容易進行中心導體之對預 置的定位作業。 又，本發明的同軸連接器的特徵是具備：具有一個以 上述各特徵之同軸連接器用接點。 施方式】 以下，參照第1至5圖說明本發明的實施形態之同軸 器用接點及具備該接點的同軸連接器。 如第1圖所示，本實施形態的同軸連接器用接點1是 加工板狀金屬才來形成的。再者，可舉出鐵、鋁、銅 金屬及以這些金屬爲主成分的合金作爲板狀金屬材。 連接器用接點1是具有供同軸電纜20的中心導體2 1 ，且利用銲錫6

1的前端側的結線部2的纟而部。另一方 面，所謂結線部2的後端部是指，位於中心導體21的後 端側（根部側）的結線部2的端部。又’所謂左右方向是 指，對中心導體2 1的軸心方向A呈正交（垂直）’且對 結線部2的上面呈平行的方向。又，上下方向是指’對中 心導體21的軸心方向A呈正交（垂直）’且對結線部2 的上面呈正交（垂直）的方向。 如上所述的結構的同軸連接器用接點1是如第1圖所 示’形成收容於外殼3 0。外殼3 0是利用將絕緣材料進f了 塑模成形來形成的。在此，能夠使用PBT系、尼龍系、 P P S系或L C P系等的合成樹脂材料且具有絕緣性的所有材 料來作爲絕緣材料。外殻3 0是具有··大致呈圓筒形狀的 外殼本體31、用來覆蓋接點的上方之外殻蓋32、及保持 外殻本體3 1與外殼蓋3 2的抵接狀態用的第1卡止機構 33 〇 外殼蓋3 2是形成外殼本體3 1的上緣部的其中一方側 爲固定端。又，外殼蓋3 2是利用在固定端曲折，使得自 由端可抵接於外殼本體3 1的上緣部的另一方側，並且’ -11 - (7) (7)200306039 覆蓋接點的上方。又，在外殻蓋32的下面，形成有用來 挾持接點固定部1 2的凸部1 4。 上述外殼本體3 1是在上側及下側分別具有上側外殼 部40與下側外殼部4丨。又，外殼本體3 1是在中心部具 備有用來收容同軸連接器用接點1的接點收容孔3 7。接 點收容孔3 7是由外殼本體3 1的上面至下面連通著。上側 外殼部40的接點收容孔3 7是形成收容接點固定部1 2、 延設部1 5、結線部2及後端側定位部4。另一方面，下側 外殼部4 1的接點收容孔3 7是形成收容接觸部9· 9。 上述接點收容孔3 7是具有用來收容接點固定部1 2的 第1收容部37a。第1收容部37a是形成及配置於外殻本 體3 1使得供外殻蓋3 2的凸部14所嵌合。又，第1收容 部3 7a與凸部1 4是利用挾持接點固定部1 2，來將接點1 1 在穩定的狀態下固定於外殼3 0內。 再者，凸部14對上述第1收容部3 7a的嵌合是利用 壓入來進行爲佳。藉此，接點固定部12在第1收容部 3 7a與凸部1 4利用壓入來挾持，故可將接點1 1於穩定的 狀態下且緊固地固定於外殼3 0內。 又，上側外殼部40是具備本體側卡止部3 4。本體側 卡止部3 4是配置於外殼本體3 1的上緣部的另一方側。本 體側卡止部34是具有：設定成預定寬度的嵌合槽34a、 由嵌合槽34a的側面上端部朝內側方向突設的突起部 3 4b ·3 4b。嵌合槽34a是接點收容孔37至外周面形成於半 徑方向。 -12- (8) (8)200306039 上述本體側卡止部34是構成第1卡止機構33的一部 分。第1卡止機構3 3是除了上述本體側卡止部34以外’ 尙具備有蓋側卡止部3 5。蓋側卡止部3

針對上述結構，說明關於同軸連接器用接點1及同軸 連接器的製造方法。 (接點加工製程） 首先，準備帶狀的薄板金屬板，將此帶狀金屬板搬人 至沖壓加工裝置。在於沖壓加工裝置，利用帶狀金屬板的 寬方向的一方側作爲載體而殘留，將另一方側切斷及變形 ，來使得在未圖示的載體以等間隔連結的接點1形成連，續 狀。然後，接點1與載體一同呈滾筒狀地捲繞於捲筒。 (外殼加工製程） 在於外殼加工製程，利用射出成形等的塑模成形，來 作成外殼3 0。即，如第1及4圖所示，準備具有對應外 殼3 0的外形之模槽的模具。再者，模槽是形成能夠以1 次的射出成形來形成複數個外殼3 0爲佳。然後，將模具 女裝於射出成形機5將具備絕緣性的狀的合成樹脂材料 供給至射出成形機。然後，在於射出成形機，將合成樹脂 材料加熱及加壓來作成液狀後，壓入至模具內的模槽。利 用冷卻預定時間後開模，取出外殼3 0。 (錫焊製程） 將上述滾筒狀的接點1安裝於陸續送出裝置，將位於 -15- (11) (11)200306039 前端側的接點1安裝於用來進行熔接作業的固定具。再者 ’接點1的安裝是爲了防止銲錫流動，而設定成結線部2 的±面呈水平。然後，準備切斷成預定長度的同軸電纜 2〇。利用以剝片機等的工模將同軸電纜20的前端部進行 剝離加工，使得中心導體2 1與絕緣體24與密封導體23 分別露出。再者，中心導體2 1的露出長度是設定成與接 點1的前端側定位部3與後端側定位部4之間隔大致相等 的値’使得中心導體2 1的前端部位於前端側定位部3內 。又，同軸電纜20是亦可預先準備已進行剝離加工者。 其次，已進行剝離加工的同軸電纜20朝固定具的接 點1的上方移動。將同軸電纜20安裝於接點1，使得中 心導體2 1抵接於接點1的結線部2。此時，同軸電纜2 0 的絕緣體24的端面抵接於後端側定位部4的定位片7。 藉此，中心導體2 1在於結線部2的前後方向被定位。此 結果，使得中心導體2 1的根部側也就是後端部位於後端 側定位部4的導引槽8內。此結果，利用以後端側定位部 4可支承中心導體2 1之後端部，來將中心導體2 1之主要 是後端部對預定位置定位於左右方向的容許範圍內。 然後，一邊維持中心導體21抵接著結線部2的狀態 ，一邊利用錫焊來將中心導體2 1結線於結線部。當進行 錫焊時，液體狀的銲錫60是由中心導體2 1朝結線部2的 外側流動。此時，由於在由結線部2朝中心導體21的軸 心方向A偏移的部位形成有接觸部9 ·9 ’故，由結線部2 上的錫焊位置至接觸部9 ·9爲止的距離較長。因此，即使 -16- (12) (12)200306039 在例如錫焊量較通常的使用量稍許變多，或受到在其他的 錫焊條件產生參差不齊而使得銲錫60在廣泛的範圍內流 動的情況時，銲錫60也不易流出至接觸部9· 9。 且’由於結線部2之挟持中心導體的兩端部是位於由 錫焊位置起算最近的位置，故，流動於結線部2的銲錫 60是最初到達結線部2的兩端部，但，可利用兩端部的 防止流動壁17·17阻止銲錫60的流動，來防止銲錫60由 兩端部朝接觸部9·9行進。藉此，能夠減輕進行錫焊作業 者的負擔，並且，能夠提高成品率及生產性。 當完成上述錫焊作業時，接點1由未圖示的載體切離 。然後，接點1由固定具脫離，而被搬運至下一個製程的 安裝製程。 (安裝製程） 在於安裝製程，首先將殼體5 1安裝於未圖示的安裝 裝置。然後，將外殻30安裝於此殼體5 1的外殼主收容部 5 4。此時，利用外殼本體3 1的電纜收容部42收容於殼體 本體5 2的外殼副收容部5 5，使得外殼3 0形成對殻體本 體5 2呈水平面內固定的狀態。 其次，將在錫焊製程所做成的具有同軸電纜20之接 點1插入至外殼本體3 1的接點收容孔3 7。然後利用將同 軸電纜20的絕緣體24收容於電纜收容部42的收容槽 4 2 a，來做成將接點i對外殻本體3 1呈水平面內固定的狀 態。然後，利用彎曲外殼蓋3 2的固定端部，來將外殼蓋 -17- (13) (13)200306039 3 2朝外殻本體31傾倒，使得外殼蓋3 2的自由端側抵接 於外殼本體3 1的上緣部的另一側。藉此，利用將外殼蓋 3 2關閉，使得藉由外殻蓋3 2覆蓋接點1的上方。 又，當利用外殼蓋3 2的傾倒，使外殼蓋3 2的自由端 側抵接於外殻本體3 1的上緣部的另一方側時，外殼蓋3 2 的蓋側卡止部3 5嵌合於外殼本體31的本體側卡止部3 4 。此結果，藉由蓋側卡止部3 5的階段部3 5 b · 3 5 b抵接於 本體側卡止部34的突起部34b· 34b，使得蓋側卡止部35 與本體側卡止部3 4形成卡止狀態。此卡止狀態是外殼蓋 3 2傾倒的狀態，換言之，產生作用成保持外殼蓋3 2的自 由端側與外殻本體3 1的上緣部的另一方側的抵接狀態之 保持力。 此時，如上所述，第1卡止機構3 3是被配置於由外 殼蓋3 2的固定端充分遠離的自由端側。因此，比起例如 將相當於第1卡止機構33的卡止機構設於外殼蓋32的根 部側的情況，對外殼蓋3 2的保持力作爲大的力矩來發揮 作用。其結果，由於能夠以大的力矩使保持力發揮作用， 故，能確實地進行外殼蓋3 2的抵接狀態。 又，如上所述，當外殼蓋3 2呈關閉的狀態時，蓋部 3 2 a覆蓋同軸電纜2 0的絕緣體2 4的上方。藉此，即使在 對同軸電纜20賦予朝上方的推上力的情況，也能夠防止 同軸電纜20的絕緣體24的浮起。且，由於以第1收容部 3 7a與凸部1 4來挾持接點固定部1 2，故，可將接點1丨在 外殼3 0內呈穩定的狀態下固定。 -18- (14) (14)200306039 其次，利用殼體蓋構件5 3的連接部5 3 a彎曲，使得 殻體蓋構件53朝殻體本體52方向傾倒。然後，以第1蓋 部 5 3 b覆蓋著收容有接點1的外殼本體3 1的外殼部 40·41。又，以第2蓋部53c來覆蓋收容於電纜收容部42 的同軸電纜20的絕緣體24。且，將密封導體23及外皮 22分別抵接及壓接於導體壓接部53d及外皮壓接部53e ° 其結果，能夠作成：將錫焊結線有同軸電纜20的中心導 體2 1之接點1、與連接有密封導體23的殼體5 1在外殼 本體31被作成電絕緣的結構之同軸連接器6 1。再者，在 關閉殼體蓋構件5 3作成同軸連接器的情況時，外殼蓋3 2 維持對外殼本體3 1呈關閉的狀態。因此，由於在外殼3 0 內接點1以正規的收容姿勢被收容，故，能夠以高的成品 率來作成優良品質的同軸連接器。 如上所述，本實施形態的同軸連接器用接點1是如第 1圖所示，具有：一邊供同軸電纜20的中心導體2 1抵接 ，一邊利用銲錫6 0來結線的結線部2 ;與在由結線部2 朝中心導體2 1的軸心方向遠離的部位，對軸心呈左右對 稱地下垂形成，利用具有彈性，來在彈推的狀態下嵌合於 對方側連接器的接觸部9·9 ° 在於上述結構，當將中心導體2 1錫焊於結線部2時 ，熔融狀態的銲錫60是朝結線部2的外側流動。此時， 由於在由結線部2朝中心導體2 1的軸心方向遠離的部位 形成有接觸部9·9，故’由結線部2上的錫焊位置到接觸 部9 · 9爲止的距離較長。因此’即使在例如錫焊量較通常 -19- (15) (15)200306039 的使用量稍許變多，或受到在其他的錫焊條件產生參差不 齊而使得銲錫60在廣泛的範圍內流動的情況時，銲錫60 · 也不易流出至接觸部9·9。藉此，能夠減輕進行錫焊作業 者的負擔，並且，能夠提高成品率及生產性。 又，在於本實施形態，在結線部2之挾持中心導體 2 1的兩端部，形成有阻止銲錫 60流動的防止流動壁 17· 17。藉此，利用防止流動壁17·17阻止銲錫60的流動 ，使得能夠防止銲錫60由兩端部朝接觸部9·9行進。 鲁200306039 (1) 发明 Description of the invention [Technical field to which the invention belongs] The present invention relates to a contact for a coaxial connector used in an electronic device such as an information terminal device or a computer-related device, and a coaxial connector provided with the contact. [Prior art] Coaxial cables used in electronic equipment such as information terminal equipment or computer-related equipment are provided with these components in order from the outer peripheral side to the center outer sheath, sealed conductor, insulator, and central conductor, and the grounded potential is a sealed conductor. Located around the center conductor that transmits and receives data signals. Therefore, usually, the coaxial cable has its end as a connector, so that the central conductor and the sealed conductor can be easily connected on the signal side and the ground side of the electronic substrate. When the end portion of the coaxial cable is used as a connector, the center conductor, the insulator, and the sealed conductor are cut and exposed, respectively. Then, the center conductor of the coaxial cable is soldered while abutting against the flat junction portion of the contact for the coaxial connector. When soldering, liquid solder flows on the junction portion. Therefore, when the amount of solder is large, the solder flows out from the junction portion and floods back into the contact portions formed on the left and right sides of the junction portion, resulting in a decrease in elasticity (quality). In particular, when the solder is detoured into the inside of the contact portion, not only the elasticity is reduced, but also the electrical contact is destabilized. Therefore, for example, Japanese Patent Application Laid-Open No. 200 1-43 93 9 discloses that wall portions are formed at the front end portion and the rear end portion of the knot portion in the axial direction of the center conductor, and the center conductor is located between these wall portions. Structurer. According to this structure (2) (2) 200306039, the soldering operation to the junction portion of the center conductor is performed between the wall portions. Therefore, the wall portions at both end portions have a function of blocking the outflow of solder, so that the outflow of solder to the contact portion can be prevented. However, in the above-mentioned conventional structure, it is not possible to sufficiently prevent solder from flowing out to the contact portion. That is, as described above, even if the wall portions' are provided at the front end portion and the rear end portion of the knot portion, it is possible to prevent the solder from flowing out in the front-back direction, but it is also impossible to prevent the solder from flowing out in the left-right direction. Further, since the contact portions are formed on the left and right sides of the junction portion, the distance from the soldering position on the junction portion to the contact portion is extremely small. Therefore, even if, for example, the amount of solder is slightly larger than the normal usage amount, the solder flowing in the left-right direction flows to the contact portion, and the elasticity of the contact portion decreases. As a result, an excessive burden is placed on a soldering operator, and the finished product and productivity are liable to decrease. Accordingly, an object of the present invention is to provide a coaxial connector contact capable of sufficiently preventing solder from flowing out to a contact portion, and a coaxial connector including the same. [Summary of the Invention] The present invention discloses that the contact for a coaxial connector of the present invention is characterized by having a junction portion for abutting the center conductor of the coaxial cable and soldering with solder; and a junction portion facing the center from the junction portion to the junction portion. The position where the axial direction of the conductor is offset is formed symmetrically depending on the left and right sides, and the elastic part is fitted to the contact portion of the counterpart connector in the elastically pushed state. In the above configuration, when the center conductor is soldered to the junction portion, the solder in the molten (3) (3) 200306039 state flows toward the outside of the junction portion. In this case, since the contact portion is formed from a position shifted from the junction portion toward the axial direction of the center conductor, the distance from the soldering position on the junction portion to the contact portion is long. Therefore, even if, for example, the amount of solder is slightly larger than the usual amount of use, or subject to unevenness in other soldering conditions, it is difficult for the solder to flow out to the contact portion when the solder flows in a wide range. Thereby, the burden on the operator who performs soldering can be reduced, and the yield and productivity can be improved. Further, the contact for a coaxial connector of the present invention is characterized in that a flow-preventing wall for preventing solder from flowing is formed at both end portions of the junction portion that hold the center conductor. According to the above-mentioned structure, since both ends of the center conductor held by the junction portion are formed closest to each other by the soldering position, the solder flowing in the junction portion first reaches both ends of the junction portion, but both ends can be used. The flow prevention portion of the portion prevents the flow of the solder, so that the solder can be prevented from traveling from the both end portions to the contact portion. As a result, it is possible to make the solder less likely to flow out to the contact portion. The contact for a coaxial connector according to the present invention is characterized in that: the contact for a coaxial connector is provided on a front end portion side of the center conductor, and a side front end side positioning portion that supports the center conductor on both sides is formed; and a root portion of the center conductor is provided. On the side, a side surface ′ that supports the center conductor from both sides is formed, and an end-side positioning portion is formed abutting on the end surface of the dielectric covering the center conductor. According to the above structure, when the center conductor of the coaxial cable abuts the junction portion, the front end positioning portion and the rear end positioning portion can be used to restrict the position of the front end and the root of the center conductor in the left-right direction to make the center -8-(4) 200306039 The core of the conductor reduces the coaxial abutment structure 23 which can be used for positioning [real connection and utilization, etc.]-It is used to accurately position the overall position of the wire at a predetermined position of the junction. In addition, by using the rear-end positioning portion to abut the end surface of the dielectric, the conductor can be accurately positioned in the axial direction, that is, the front-rear direction. This junction can reduce the positional deviation of the center conductor of each product, and can vary the quality. In addition, when soldering the center conductor, it is possible to prevent the quality deterioration caused by the solder flowing from the junction portion to the contact portion, and it is easy to perform the positioning operation of the center conductor in advance without using a special external device. Further, the coaxial connector of the present invention is characterized by having a coaxial connector contact having one of the features described above.

A convex portion 14 for holding the contact fixing portion 12 is formed on the lower surface of the case cover 32. The case body 31 has an upper case portion 40 and a lower case portion 4 丨 on the upper and lower sides, respectively. The housing body 31 is provided with a contact receiving hole 37 for accommodating the contact 1 for the coaxial connector at the center. The contact accommodating holes 37 are communicated from the upper surface to the lower surface of the housing body 31.

On the other hand, the contact accommodating holes 37 of the lower housing portion 41 are formed to receive the contact portions 9.9. The contact accommodating hole 37 is a first accommodating portion 37a having a contact fixing portion 12 therein. The first accommodating portion 37a is formed and arranged on the case body 31 so that the convex portion 14 to which the case cover 32 is fitted. In addition, the first accommodating portion 37a and the convex portion 14 use the pinch contact fixing portion 12 to fix the contact 11 in the housing 30 in a stable state. The fitting of the convex portion 14 to the first receiving portion 37a is preferably performed by press-fitting. With this, the contact fixing portion 12 is held by the first receiving portion 37a and the convex portion 14 by press-fitting, so that the contact 11 can be firmly fixed in the housing 30 in a stable state. The upper case portion 40 is provided with a main body side locking portion 34. The body-side locking portion 34 is disposed on the other side of the upper edge portion of the case body 31. The body-side locking portion 34 is provided with a fitting groove 34a set to a predetermined width, and a protruding portion 3 4b · 3 4b protruding from the upper end portion of the side surface of the fitting groove 34 inward. The fitting groove 34a is formed in the radial direction from the contact accommodation hole 37 to the outer peripheral surface. -12- (8) (8) 200306039 The above-mentioned main body side locking portion 34 is a part of the first locking mechanism 33. The first locking mechanism 33 is provided with a cover-side locking portion 35 in addition to the main body-side locking portion 34 '. The cover-side locking portion 35 is disposed on the free end side of the case cover 32. The cover-side locking portion 35 is a projecting piece 3 a having a substantially central portion protruding from the free end of the housing cover 32. The width of the projection pieces 3 5 a is set to be equal to the projections 34 b. 34 b. Further, step portions 3 5 b · 3 5 b are formed on both sides of the protruding piece 35a. The width of the step portion 3 5a plus the step portion 3 5 b · 3 5b is set to be slightly narrower than the groove width of the fitting groove 34a. The step portions 35b.35b are when the protruding pieces 35a are fitted into the fitting grooves 34a, and the upper surfaces thereof abut against the protruding portions 34b.34b. The contact between the step portions 35b * 35b and the protruding portions 34b * 34b at this stage is to generate a holding force for maintaining the state where the case cover 32 abuts against the case body 31. As shown in FIG. 4, a cable housing portion 42 for housing the insulator 24 of the coaxial cable 20 is formed on the upper housing portion 40 of the housing body 31. The cable accommodating portion 42 is formed in a direction orthogonal (vertical) to the longitudinal direction of the case cover 32 that abuts against the case body 31 and faces the center portion of the case body 31. A cover portion 3 2 a is formed in the case cover 32. The cover portion 32a is disposed above the insulator 24 of the coaxial cable 20 accommodated in the cable accommodation portion 42. Then, "this cover part 3 2a can cover the insulator 24 and apply upward force to the coaxial cable 20" to prevent the insulator 24 from floating. The casing 30 having the structure described above is formed to be housed in a casing 51 (shell). The case 51 is formed by processing a metal plate. Here, as the metal plate, metals such as iron, aluminum, or copper, and alloys containing these metals as main components can be cited. The case 51 includes a case body 52 for accommodating the case 30, and a case cover member 53 provided integrally with the case body 52. The casing body 52 includes a casing main storage portion 54 and a casing sub-accommodation portion 55. The main housing accommodating portion 54 is formed in a cylindrical shape with an upper surface and a lower surface open, and is used for accommodating the upper housing portion 40 and the lower housing portion 41 of the housing body 31. The casing sub-receiving portion 55 is formed in a box-like shape with an open upper surface and accommodates the cable accommodating portion 42 of the casing main body 31. On the other hand, the case cover member 53 is provided on the upper edge portion of the case main housing portion 54. The case cover member 53 is disposed to face the case sub-receiving portion 55 and is bendable at the connection portion 53a. The case cover member 53 includes a first cover portion 53 b for covering the upper surface of the main housing receiving portion 54, a second cover portion 53 c that covers the upper surface of the auxiliary housing receiving portion 55, and a sealed conductor 23 crimped to the coaxial cable 20. The conductor crimping portion 53d of the conductor and the sheath crimping portion 53e of the sheath 22 of the coaxial cable 20 are crimped. Then, the case cover member 53 before bending is made to stand vertically against the main housing accommodating portion 54. The upper surface of the main housing accommodating portion 54 can be opened to accommodate the housing 30. In addition, when the case cover member 53 is bent at the connection portion 5 3a so as to fall over the case body 52, the first cover portion 53b and the second cover portion 5 3c are respectively covered and housed in the case body. 5 2 of the housing body 3 1 can be crimped to the sealed conductor 23 of the coaxial cable 20 by crimping the conductor crimping portion 53d on the upper side of the housing portion 40 and the cable accommodating portion 42. The above-mentioned case cover member 53 is configured such that, when the case cover member 53 has been poured onto the case body 52, the longitudinal direction of the case cover member 53 is orthogonal (vertical) to the longitudinal direction of the case cover 32. It should be noted that the case cover member 53 can be arranged at any position as long as it is in a positional relationship with the case -14- (10) (10) 200306039 where the cover 32 does not overlap in a vertical standing state. With regard to the above-mentioned structure, the contact 1 for a coaxial connector and a method for manufacturing the coaxial connector will be described. (Contact processing process) First, a strip-shaped thin metal plate is prepared, and the strip-shaped metal plate is transferred to a press processing apparatus. In the press processing device, one side of the strip-shaped metal plate in the wide direction is left as a carrier, and the other side is cut and deformed, so that the contacts 1 connected at equal intervals on the carrier (not shown) are connected, and continued. shape. Then, the contact 1 is wound around the reel in a roll shape together with the carrier. (Shell processing process) In the shell processing process, the shell 30 is made by molding such as injection molding. That is, as shown in Figs. 1 and 4, a mold having a mold groove corresponding to the outer shape of the casing 30 is prepared. In addition, it is preferable that the die groove is formed so that a plurality of shells 30 can be formed by a single injection molding. Then, the injection mold forming machine 5 supplies the mold with a synthetic resin material having an insulating shape to the injection molding machine. Then, the injection molding machine heats and pressurizes the synthetic resin material to form a liquid, and then presses the synthetic resin material into a cavity in the mold. After cooling for a predetermined time, the mold is opened and the casing 30 is removed. (Soldering process) The above-mentioned roller-shaped contact 1 is installed in the successive feeding device, and the contact 1 at the front end side of -15- (11) (11) 200306039 is installed in a fixture for welding operation. Furthermore, the mounting of the 'contact 1 is to prevent the solder from flowing, and the ± plane of the junction portion 2 is set to be horizontal. Then, the coaxial cable 20 is cut to a predetermined length. The front end portion of the coaxial cable 20 is peeled using a die such as a chipper so that the center conductor 21, the insulator 24, and the sealed conductor 23 are exposed, respectively. The exposed length of the center conductor 21 is set to be approximately equal to the interval between the front-end positioning portion 3 and the rear-end positioning portion 4 of the contact 1 so that the front end of the center conductor 21 is located at the front-end positioning portion. 3 within. The coaxial cable 20 may be prepared in advance. Next, the coaxial cable 20 that has been subjected to the peeling process is moved above the contact 1 of the fixture. The coaxial cable 20 is mounted on the contact 1 so that the center conductor 21 abuts on the junction portion 2 of the contact 1. At this time, the end face of the insulator 24 of the coaxial cable 20 abuts on the positioning piece 7 of the rear-end-side positioning portion 4. Thereby, the center conductor 21 is positioned in the front-back direction of the junction portion 2. As a result, the root side, that is, the rear end portion, of the center conductor 21 is positioned in the guide groove 8 of the rear end side positioning portion 4. As a result, the rear end portion of the center conductor 21 can be supported by the rear end side positioning portion 4, so that the rear end portion of the center conductor 21 can be positioned within the allowable range in the left-right direction, mainly at the rear end portion. Then, while maintaining the state where the center conductor 21 abuts the junction portion 2, the center conductor 21 is connected to the junction portion by soldering. When soldering is performed, the liquid solder 60 flows from the center conductor 21 toward the outside of the junction portion 2. At this time, since the contact portion 9 · 9 ′ is formed at a position offset from the junction portion 2 in the axial direction A of the center conductor 21, the distance from the soldering position on the junction portion 2 to the contact portion 9 · 9 Longer. Therefore, even if -16- (12) (12) 200306039 is used, for example, the amount of solder is slightly larger than the usual amount, or it is subject to unevenness in other soldering conditions, which causes the solder 60 to flow in a wide range. In this case, it is difficult for the solder 60 to flow out to the contact portion 9.9. Moreover, since both ends of the holding center conductor of the knot portion 2 are located closest to the soldering position, the solder 60 flowing through the knot portion 2 reaches the both ends of the knot portion 2 first, but it can be used The flow prevention walls 17 · 17 at both end portions prevent the flow of the solder 60 to prevent the solder 60 from advancing from the both end portions toward the contact portion 9 · 9. Thereby, the burden on the soldering operator can be reduced, and the yield and productivity can be improved. When the above soldering operation is completed, the contact 1 is cut off by a carrier (not shown). Then, the contact 1 is detached by the fixture, and is transferred to the installation process of the next process. (Installation process) In the installation process, the housing 51 is first attached to a mounting device (not shown). Then, the case 30 is attached to the case main accommodation portion 54 of the case 51. At this time, the cable accommodating portion 42 of the casing body 31 is accommodated in the casing sub-accommodating portion 55 of the casing body 52, so that the casing 30 is fixed to the casing body 52 in a horizontal plane. Next, the contact 1 having the coaxial cable 20 made in the soldering process is inserted into the contact receiving hole 37 of the case body 31. Then, the insulator 24 of the coaxial cable 20 is accommodated in the accommodation groove 4 2 a of the cable accommodation portion 42 to make the contact point i fixed to the housing body 31 in a horizontal plane. Then, the housing cover -17- (13) (13) 200306039 3 2 is tilted toward the housing body 31 by bending the fixed end portion of the housing cover 32 so that the free end side of the housing cover 32 abuts against the housing body 3 1 on the other side of the upper edge. Thereby, the housing cover 32 is closed so that the upper part of the contact 1 is covered by the housing cover 32. In addition, when the free end side of the case cover 32 is brought into contact with the other side of the upper edge portion of the case body 31 by the tilting of the case cover 32, the cover-side locking portion 3 5 of the case cover 3 2 The body-side locking portion 3 4 is fitted in the case body 31. As a result, the step portion 3 5 b · 3 5 b of the cover-side locking portion 35 abuts on the protruding portions 34 b · 34 b of the body-side locking portion 34, so that the cover-side locking portion 35 is locked with the body side. The sections 34 are locked. This locked state is a state in which the housing cover 32 is tilted, in other words, a holding force is generated to keep the free end side of the housing cover 32 in contact with the other side of the upper edge portion of the housing body 31. At this time, as described above, the first locking mechanism 33 is disposed on the free end side sufficiently away from the fixed end of the case cover 32. Therefore, compared with, for example, a case where a locking mechanism corresponding to the first locking mechanism 33 is provided on the root side of the housing cover 32, the holding force on the housing cover 32 acts as a large moment. As a result, since the holding force can be exerted with a large torque, the contact state of the case cover 32 can be reliably performed. As described above, when the housing cover 32 is closed, the cover portion 3 a covers the upper portion of the insulator 24 of the coaxial cable 20. Accordingly, even when the upward pushing force is applied to the coaxial cable 20, it is possible to prevent the insulator 24 of the coaxial cable 20 from floating. In addition, since the contact fixing portion 12 is held by the first receiving portion 37a and the convex portion 14, the contact 1 丨 can be fixed in a stable state in the housing 30. -18- (14) (14) 200306039 Next, the connection portion 5 3 a of the case cover member 53 is bent so that the case cover member 53 is tilted toward the case body 52. Then, the first cover portion 5 3 b covers the case portion 40 · 41 of the case main body 31 accommodating the contact 1. Moreover, the insulator 24 of the coaxial cable 20 accommodated in the cable accommodation portion 42 is covered with the second cover portion 53c. In addition, the sealed conductor 23 and the sheath 22 are brought into contact with and crimped to the conductor crimping portion 53d and the sheath crimping portion 53e °, respectively. As a result, it is possible to solder the wires to the contacts of the center conductor 21 of the coaxial cable 20 1. A coaxial connector 61, which is electrically insulated from a housing 51, to which a sealed conductor 23 is connected, in a housing body 31. When the housing cover member 53 is closed to form a coaxial connector, the housing cover 3 2 remains closed to the housing body 31. Therefore, since the contact point 1 is accommodated in the regular storage position in the housing 30, it is possible to produce a high-quality coaxial connector with a high yield. As described above, the contact 1 for a coaxial connector according to the present embodiment has the junction portion 2 for connecting the center conductor 21 of the coaxial cable 20 with solder 60 while making contact with the center conductor 21 of the coaxial cable 20; and In the portion away from the center line 21 in the axial direction of the center conductor 21, the left and right sides are symmetrically dangling from the center of the axis. The elastic part is used to fit the contact portion 9 of the counterpart connector in a state of being pushed. 9 ° is in the above structure. When the center conductor 21 is soldered to the junction portion 2, the molten solder 60 flows toward the outside of the junction portion 2. At this time, since the contact portion 9 · 9 is formed at a portion away from the junction portion 2 in the axial direction of the center conductor 21, the distance from the soldering position on the junction portion 2 to the contact portion 9 · 9 is relatively long. long. Therefore, even if, for example, the amount of solder is slightly larger than the usual amount of -19- (15) (15) 200306039, or due to unevenness in other soldering conditions, which causes the solder 60 to flow in a wide range In this case, it is difficult for the solder 60 · to flow out to the contact portion 9 · 9. Thereby, the burden on the soldering operator can be reduced, and the yield and productivity can be improved. Further, in this embodiment, flow prevention walls 17 · 17 are formed on both ends of the holding center conductor 21 of the junction portion 2 to prevent the solder 60 from flowing. Thereby, the flow of the solder 60 is prevented by the flow prevention wall 17 · 17, so that the solder 60 can be prevented from traveling from both end portions to the contact portion 9 · 9. Lu
又，根據理想的實施例對本發明進行說明，但，本發 明是在不超出其領域的範圍內可進行各種變更。即，同軸 連接器用接點1是如第5圖所示，亦可作成下述結構··具 有：設在中心導體2 1的前端部側，形成可由兩側支承中 心導體2 1的側面之前端側定位部3 ;及設在中心導體2 1 的根部側，形成可由兩側支承中心導體的側面，並且，形 成可抵接於覆蓋中心導體2 1的絕緣體24 (介電質）的端 面之後端側定位部4。 I 具體而言，即在結線部2的前端部及後端部分別設置 前端側定位部3及後端側定位部4。這兩個前端側及後端 側定位部3 ·4是在中心導體2 1的軸心方向的複數個處所 _ 可支承中心導體2 1，使得中心導體2 1定位於結線部2的 預定位置。設在結線部2的前端部的前端側定位部3是具 有載置中心導體2 1的前端部用的載置部6 ;及以載置部6 爲中心，左右一對地配置的支承片5 · 5。載置部6是形成 由結線部2的中心部朝前方突出的狀態。又，支承片5 · 5 -20- (16) (16)200306039 是利用將前端側定位部3的左右方向的一部分挖起成豎立 狀態來形成的，在中心導體2 1的兩側分別相對向著。 支承片5 · 5的間隔是設定成與中心導體2 1的直徑相 等或較其稍廣程度，使得能夠由兩側來支承中心導體2 i 的側面。再者，上述的間隔是設定成：在將兩支承片5 · 5 的中心位置作成在預定位置的情況時，即使由此預定位置 偏移，也不會對錫焊作業產生障礙的程度爲佳。藉此，前 端側定位部3是能夠利用支承片5 · 5來將最容易由結線部 2的預定位置偏移的中心導體2 1的前端部位置限定於左 右方向。且，前端側定位部3是由於能夠在前後方向之寬 廣的範圍使支承片5 · 5存在，故，在也露出的中心導體 2 1的長度上有稍許的誤差，也能夠使中心導體21的前端 部確實地位於支承片5 · 5之間。 再者，在於本實施形態，將兩支承片5 · 5挖起形成豎 立狀態，但，亦可使由下部至上部的全體朝內側彎曲。在 此情況時，前端側定位部3是能利用兩支承片5 · 5的間隔 由下部至上部減少，來高精準度地進行定位部之中心導體 的左右方向及上下方向的定位。又，兩支承片5·5是亦可 下部至上部的全體朝內側傾斜，亦可由下部至上部直立， 且僅上部朝內側方向彎曲或曲折。 若根據上述結構的話，當同軸電纜20的中心導體2 1 抵接於結線部2時，可利用以前端側定位部3與後端側定 位部4將此中心導體21的前端部及根部位置限定於左右 方向，來使得能夠將中心導體21的全體精準度良好地定 (17) (17)200306039 位於結線部2的預定位置。又，利用後端側定位部4抵接 於絕緣體24 (介電質），來使得即使在軸心方向 A也就 是前後方向上將中心導體2 1正確地定位。其結果’能夠 減低每個製品的中心導體的位置偏移，降低品質的參差不 齊。又，更能夠防止當對中心導體2 1進行錫焊作業時銲 錫60由結線部2朝接觸部9·9流出所造成的品質降低， 並且，不須特別的外部裝置也可容易進行中心導體2 1對 預定位置的定位作業。 【產業上的利用可能性】 如上述做過說明的同軸連接器用接點及具備該接點的 同軸連接器是能夠適用於資訊終端機器或電腦關聯機器等 的電子機器等等。 【圖式簡單說明】 第1圖是顯示同軸連接器用接點被收容於外殻的狀態 的說明圖。 第2圖是同軸連接器用接點的斜視圖。 第3圖是顯示同軸連接器接點的結構，（a )爲正面 圖、（b)爲側面圖、（c)爲平面圖。 第4圖是顯示同軸連接器的組裝的狀態之說明圖。 第5圖是顯示同軸連接器用接點被收容於外殼的狀態 的說明圖。 -22- (18) 200306039 〔圖號說明〕 1 同 2 結 3 刖 4 後 5 支 6 載 7 定 8 導 9 接 11 接 12 接 1 4 凸 15 延 17 防 20 同 2 1 中 22 外 23 密 24 絕 3 0 外 3 1 外 3 2 外 3 2a 蓋 軸連接器用接點 線部 端側定位部 端側定位部 承片 置部 位片 引槽 觸部 點 點固定部 部 設部 止流動壁 軸電纜 心導體 皮 封導體 緣體 殻 殼本體 殼蓋 部The present invention has been described based on the preferred embodiments. However, the present invention can be modified in various ways without departing from the scope of the present invention. That is, as shown in FIG. 5, the coaxial connector contact 1 can also be constructed as follows: it is provided on the front end side of the center conductor 21 to form a side front end that can support the center conductor 21 on both sides The side positioning portion 3 is provided on the root side of the center conductor 21 to form a side surface that can support the center conductor on both sides, and forms a rear end that can abut on the end face of the insulator 24 (dielectric) covering the center conductor 21.侧 定位 部 4。 Side positioning portion 4. I Specifically, the front-end positioning portion 3 and the rear-end positioning portion 4 are provided at the front end portion and the rear end portion of the knot portion 2, respectively. The two front-side and rear-side positioning portions 3 · 4 are a plurality of spaces in the axial direction of the center conductor 21. The center conductor 21 can be supported so that the center conductor 21 is positioned at a predetermined position of the junction portion 2. The front-end positioning portion 3 provided at the front end portion of the knot portion 2 is a mounting portion 6 having a front end portion on which the center conductor 21 1 is mounted; · 5. The mounting portion 6 is formed so as to protrude forward from the center portion of the knot portion 2. The support piece 5 · 5 -20- (16) (16) 200306039 is formed by digging a part of the front-side positioning portion 3 in the left-right direction into an upright state, and the two sides of the center conductor 21 are opposed to each other . The interval between the support pieces 5 · 5 is set to be equal to or slightly wider than the diameter of the center conductor 21 so that the sides of the center conductor 2 i can be supported from both sides. In addition, the above-mentioned interval is set such that when the center positions of the two supporting pieces 5 · 5 are set at a predetermined position, even if the predetermined position is shifted, the degree of the soldering work is not hindered. . Thereby, the front end side positioning portion 3 can limit the position of the front end portion of the center conductor 21 which is most likely to be shifted from the predetermined position of the junction portion 2 by the support pieces 5 · 5 to the left and right directions. In addition, since the front-side positioning portion 3 can support the supporting pieces 5 and 5 in a wide range in the front-rear direction, there is a slight error in the length of the center conductor 21 that is also exposed, and the center conductor 21 can also be The front end portion is surely located between the supporting pieces 5 · 5. Furthermore, in this embodiment, the two supporting pieces 5 · 5 are dug up to form a standing state, but the entirety from the lower portion to the upper portion may be bent inward. In this case, the front-end positioning portion 3 can reduce the distance between the two supporting pieces 5 · 5 from the lower portion to the upper portion to accurately position the center conductor of the positioning portion in the left-right direction and the up-down direction. The two supporting pieces 5 · 5 may be inclined from the lower part to the upper part toward the inside, or may be erected from the lower part to the upper part, and only the upper part may be bent or bent toward the inner side. According to the above structure, when the center conductor 2 1 of the coaxial cable 20 abuts on the junction portion 2, the front-end positioning portion 3 and the rear-end positioning portion 4 can be used to define the front and root positions of the center conductor 21. In the left-right direction, the entire accuracy of the center conductor 21 can be set well (17) (17) 200306039 at a predetermined position of the junction portion 2. In addition, the rear-end positioning portion 4 is in contact with the insulator 24 (dielectric), so that the center conductor 21 can be accurately positioned even in the axial direction A, but also in the front-rear direction. As a result, it is possible to reduce the positional deviation of the center conductor of each product, and reduce the quality unevenness. In addition, it is possible to prevent the quality degradation of the solder 60 from flowing out of the junction portion 2 toward the contact portions 9 · 9 when the center conductor 21 is soldered, and the center conductor 2 can be easily performed without a special external device. 1 Positioning operation for a predetermined position.
