Description of the Invention [Technical Field of the Invention] The present invention relates to a connector. [Prior Art] As disclosed in Japanese Laid-Open Patent Publication No. 2008-4404, a cable (actuator) is rotated to crimp and electrically connect a cable such as FPC or FCC via a joint. Connectors that electrically connect the cable to the circuit substrate are well known. In the connector of Patent Document 1, the joint is formed in a shape of a cross-shaped shape by a pair of beams and a connecting spring portion that connects the intermediate portions of the beams. Further, in a state in which the cable is interposed between the contact portions provided on one end side of the pair of beams so as to face each other, the other end side of the pair of beams is pressed by the rotation of the rod, so that One end side of the beam is moved in the closing direction by the connecting spring portion as a fulcrum, and the cable can be crimped by the opposing contact portion. Thus, in order to press between the other end sides of the pair of beams, a cam portion is formed at one end portion of the rod, and the cam portion is disposed between the opposing faces of one of the beams and the other of the beams. Further, by applying a load to the operation portion provided at the other end portion of the rod to rotate the lever, the cam portion is rotated so that the pressing force in the pressing direction acts between the other end sides of the pair of beams. In other words, the cam portion has a size that is pressed in the direction of the pair of beams so as to be larger in a direction perpendicular to the direction of the pressure contact, thereby exhibiting a cam function. [Claim of the Invention] -5-201222990 [Problems to be Solved by the Invention] In the above-described conventional technique, the first surface of the casing is placed in the closed state of the rod and the open state of the rod is provided. The rotation receiving portion (rotating contact surface) that abuts between the second faces of the casing makes it possible to generate a feeling of pressing when the lever is operated, but it is desirable to obtain a connector that is more sensible to feel. Accordingly, it is an object of the present invention to provide a connector which can further increase the feeling of pressing of the lever operation. [Means for Solving the Problem] In order to achieve the above object, the connector of the present invention is provided with a conductive joint that is electrically connected to a cable, and is electrically connected to each other after being crimped to the cable by a turning operation.

According to the invention, the angle between the first surface of the bottom wall portion that abuts against the rod mounting portion in the open state of the rod and the second surface of the bottom wall portion in the closed state of the rod is obtained. Since the rotation receiving portion of the cam portion is formed by forming an acute angle, the cam portion can be made narrower in width. Therefore, it is easy to rotate the rod, and when the direction of action of the moment acting on the rod exceeds a predetermined amount of rotation from the opening direction to the closing direction, the rod can be quickly rotated in the closing direction as compared with the prior art. It is possible to increase the feeling of pressing of the lever operation. [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

形。在本實施形態，連結彈簧部43係在朝上方且後方傾 斜的狀態下，將固定側接頭部4 1及可動側接頭部42予以 連結。又，當朝彈簧部47的前端與端子臂部45的前端相 對地打開之方向使彈簧部47撓曲變形時，連結彈簧部43 會彈性地撓曲變形，使得可動側接頭部42的可動側接觸 部46與固定側接頭部41的固定側接觸部44之間隔變 小。 又，在呈複數個並列設置於寬度方向Y之接頭40的 寬度方向Y兩端，如圖9所示，分別安裝有與接頭40大 -16- 201222990 致相同形狀之保持端子50，藉由此保持端子50來保持已 插入於殼體30內之電纜2(參照圖3)。 在本實施形態，接頭40的寬度方向Y兩端的保持端 子50係與接頭40同樣地，自前方被收容至殻體30的收 容部36內並被固定保持。 此保持端子50係如圖9及圖10所示，具備有：在底 壁部33附近，朝前後方向X延伸之棒狀的固定側保持部 51;和在頂壁部32附近，朝前後方向X，與固定側保持 部51在上下方向（殼體30的厚度方向：電纜2的厚度方 向）Z相對向之棒狀的可動側保持部52。又，固定側保持 部51及可動側保持部52各自的前後方向（長方向）X中 間部彼此以連結彈簧部53加以連結，形成爲略工字狀。 固定側保持部5 1係如圖9及圖1 0所示，具備有：沿 著底壁部33朝前後方向X後側（固定側保持部5 1的一 側）延伸之固定側保持臂54 ;及沿著底壁部3 3朝前後方 向X前側（固定側保持部51的另一側）延伸之支承臂 55 〇 又，在固定側保持臂54的前端部，形成有朝上方 (已插入的電纜2 )突出之固定側卡合突部54a，此固定 側卡合突部54a自下側（裏面側）插入至形成於電纜2的 寬度方向Y兩端之保持孔2c »此保持孔2c係以朝上下方 向（厚度方向）Z貫通的方式，設置於與插入至殻體30 內的狀態之電纜2的固定側卡合突部54a及後述的可動側 卡合突部56a相對應的部位。 -17- 201222990 又’在支承臂55的前端部，形成有向下突出之止擋 器55a。又，此止擋器55a係用來限制當保持端子50插 入至收容部36時之保持端子50對殼體30之最大插入 量。 且，在支承臂55的前端部，設有較縱壁部37的底面 3 7d (桿裝設部35的底面）更朝上方突出的略山形的突起 部55b’當位於開位置之桿60朝前後方向X前方移動 (平行移動）時，桿60與突起部55b相抵接。如此，突 起部55b係作爲抑制桿60脫離用之止擋器來發揮功能。 又’可動側保持部52係如圖9及圖10所示，具備 有：沿著頂壁部32朝前後方向X後側（可動側保持部52 的一側）延伸之可動側保持臂5 6 ;和沿著頂壁部3 2朝前 後方向X前側（可動側保持部52的另一側）延伸之彈簧 部57。且’在可動側保持部52之上側中央部，設有突起 部 52a。 又，在可動側保持臂56的前端部，形成有朝下方 (已插入的電纜2)突出的可動側卡合突部56a，此可動 側卡合突部5 6a自上側（表面側）插入至電纜2的保持孔 2c。再者，如圖3所示，在與電纜2的保持端子50對應 之部位，未設有導體2b。 又’在彈簧部57的下面，形成有供後的桿60的凸輪 部64滑接之略圓弧狀的凸輪面57a，在此凸輪面57&的 前側’形成有卡合突部57d，其具有：與該凸輪面57a連 設並可供凸輪部64滑接之前端面5 7b;和與該前端面5 7b -18- 201222990 連設之水平面57c。 再者，雖未圖示，保持端子50也與接頭40同樣地’ 頂壁部32覆蓋可動側保持臂56的全範圍與彈簧部57的 後側略一半範圍。又，當桿60位於開位置的狀態時’將 保持端子50卡止於殼體30，使得彈簧部57成爲不會與 頂壁部32接觸之狀態。即，在彈簧部57的上面與頂壁部 32的下面之間形成間隙》 又，在以彈簧部57的頂壁部32所覆蓋的部位（彈簧 部57的基部側：後側）與未被彈簧部57的頂壁部32所 覆蓋的部位（彈簧部5 7的前端側：前側）之大致境界部 的上部，設有階差部57e。即，如圖9所示，彈簧部57 形成爲基部的厚度較前端部的厚度更厚。 又，連結彈簧部53具有彈簧性，可彈性地撓曲變 形。又，當朝彈簧部57的前端與支承臂55的前端相對地 打開的方向使彈簧部57撓曲變形時，連結彈簧部53會彈 性地撓曲變形，使得可動側保持部52的可動側保持臂56 與固定側保持部5 1的固定側保持臂54之間隔變小。 且，在本實施形態，如圖9所示，至少當桿60位於 開位置時，將保持端子50的固定側卡合突部54a與可動 側卡合突部56a之距離D1設定成較接頭40之固定側接觸 部44的固定側接點部（前端）44a與可動側接觸部46的 可動側接點部（前端）46a之間的距離D2更短。 因此，當保持端子50的連結彈簧部53及接頭40的 連結彈簧部43各自撓曲時，在接頭40的可動側接點部 19· 201222990 46a與導體2b接觸前，保持端子50的可動側卡合突部 56a會卡合於保持孔2c。如此，在本實施形態，當使接頭 40的可動側接點部46a與導體2b接觸之際，能夠更確實 地抑制電纜2位置偏移。 再者，在本實施形態，將接頭40之固定側接觸部44 的固定側接點部（前端）44a與可動側接觸部46的可動 側接點部（前端）46a之間的距離D2設定成與電纜2的 厚度大致相等。因此，保持端子50的固定側卡合突部 54a與可動側卡合突部56a之距離（一對卡合突部間的距 離）D 1係較電纜2的厚度小。 又，在桿60的一端部，如圖1及圖2所示，以與分 別設置於接頭40及保持端子50之彈簧部47、57相對應 的方式，形成有貫通孔63。且，在桿60的與貫通孔63 鄰接之位置，形成有伴隨桿60的轉動而轉動並且滑接於 與設置在彈簧部47、57之凸輪面47a、57a相滑接的凸輪 部64(參照圖6〜圖8)。 在本實施形態，凸輪部64具備有略圓柱狀的圓形部 64a和與該圓形部64a連設之略長方體狀的方形部64b, 在前後方向X斷面視角，形成爲略鑰匙孔狀。 又，凸輪部64係與縱壁部37的底面3 7d (桿裝設部 35的底壁部）滑接，具備有：當使桿60朝開閉方向轉動 時成爲轉動支點（旋轉支點）之轉動承受面（旋轉承受 部）64c;和藉由桿60的轉動來與接頭40及保持端子50 的彈簧部47、57的凸輪面47a、57a滑接之抵接面（接頭 -20- 201222990 抵接面及保持端子抵接面）64d。 且，在凸輪部64’具備有··當將桿60作成爲全開 態時，抵接於縱壁部37的底面37d(桿裝設部35的底 部）之第1面64e ;和當將桿60作成爲全閉狀態時， 接於縱壁部37的底面37d (桿裝設部35的底壁部）之 2面64f。又’第1面64e與第2面64f所成的角度 (參照圖7)呈銳角。再者，在本實施形態，將第1 64e與第2面64f所成的角度0設定成大約77度。又， 第1面64e與第2面64f之間，設有上述的凸輪部64 轉動承受面64c，此轉動承受面64c形成作爲小的曲率 徑之圓弧面。再者，在本實施形態，將轉動承受面64c 曲率半徑設定成爲大約0.05mm。 又，在本實施形態，凸輪部64係當桿60位於開位 時，如圖6所示，形成爲朝橫方向（前後方向X )變得 長，上下方向Z的尺寸形成爲較接頭40的彈簧部47與 子臂部45之間隔及彈簧部57與支承臂55之間隔更小 即，當桿60位於開位置時，凸輪部64與彈簧部47、 形成爲非接觸狀態。 又，當使桿60朝閉方向（圖7的箭號A方向）轉 時，在轉動成凸輪部64站起的途中，凸輪部64的上下 向Z的尺寸形成爲較彈簧部47與端子臂部45之間隔及 簧部5 7與支承臂5 5之間隔更大。 即，當使桿60朝閉方向轉動時，伴隨該桿60的 動，凸輪部64以轉動承受面64c作爲轉動支點進行 狀 壁 抵 第 Θ 面 在 的 半 的 置 細 端 〇 57 動 方 彈 轉 轉 -21 - 201222990 動。又，在桿60朝閉方向轉動的途中，抵接面64d抵接 於彈簧部47、57的凸輪面47a、57a，而與凸輪面47a、 57a滑接。且，當使桿60朝閉方向轉動時，凸輪部64係 使抵接面64d —邊滑接於凸輪面47a、57a —邊轉動，使 彈簧部47、57彈性地撓曲變形，使得彈簧部47的前端與 端子臂部45的前端之間隔及彈簧部57與支承臂55之間 隔相對地打開。又，藉由伴隨彈簧部47、57的撓曲變 形，連結彈簧部43、53彈性地撓曲變形，接頭40彈性地 撓曲變形成可動側接頭部42的可動側接觸部46與固定側 接頭部41的固定側接觸部44之間隔變小，保持端子5 0 彈性地撓曲變形成可動側保持部52的可動側保持臂56與 固定側保持部5 1的固定側保持臂54之間隔變小。藉此， 在可動側接點部46a朝固定側接點部44a方向移動，而將 可動側接點部46a與固定側接點部44a壓接於電纜2之狀 態下，電纜2與接頭40被導通連接。又，可動側卡合突 部5 6a朝固定側卡合突部54a方向移動，電纜2被保持端 子50所保持。 如此，凸輪部64係對接頭40附加用來將該接頭40 壓接於電纜2之按壓力並且對保持端子50附加用來保持 電纜2之按壓力。 再者，在本實施形態，在將桿60從開位置到閉位置 向閉方向轉動時，到途中爲止，凸輪部64的高度會逐漸 變高，但當超過預定的轉動量時，凸輪部64的高度會逐 漸變低。又，因藉由彈簧部47、57的彈性復元力按壓凸 -22- 201222990 輪部64使得作用於桿6〇之力矩的作用方向會在使桿6〇 從開位置轉動至閉位置之途中，從開方向朝閉方向改變。 如此，在桿60的轉動途中，藉由縮小凸輪部64的旋 轉半徑’或使作用於桿60之力矩的作用方向從開方向朝 閉方向改變，來對進行桿60的操作時賦予按壓感。 再者，自閉方向朝開方向朝轉動時，也能夠賦予同樣 的按壓感。 又，在本實施形態，在凸輪部64的圓形部64a，如 圖6及圖11所示，形成有卡合於卡合突部47d、57d之卡 合凹部（相互地卡合的凹凸部）6 4g。此卡合凹部64g是 由可與卡合突部47d、57d的前端面47b、57b抵接之側面 6411、和可與卡合突部47(1、57(1的水平面47(：、57(；抵接 之圓弧面64i所形成。又，藉由前端面47b、57b與側面 6 4h抵接，並且水平面47c、57c與圓弧面64i抵接’使卡 合突部47d、57d與卡合凹部64g相互卡合（參照圖 12)。 即，在本實施形態，卡合突部47d、57d的前端面 47b、57b限制桿60朝前方，卡合突部47d、57d的水平 面47c、57c限制桿60朝上方移動。再者’亦可構成爲使 前端面47b、57b與側面64h及水平面47c、57c與圓弧面 64i相互地形成面接觸。藉此’可進一步提高卡合突部 47d、57d與卡合凹部64g之卡合精度。 又，在本實施形態’在彈簧部47、57與凸輪部64設 有相互地卡合的凹凸部（卡合突部47d、5 7d與卡合凹部 -23- 201222990 64g)，但此卡合突部47d、57d與卡合凹部64g在通常的 桿60的開閉操作時不會相互卡合（參照圖6 )。 又，當桿60的開閉操作時、非使用狀態（未插入有 電纜2之狀態）等時，朝向前方之荷重會施加於開狀態的 桿60，桿60呈開狀態狀態下朝前方且朝上方移動（朝桿 60對接頭40脫離的方向相對移動），而超越過略山形的 突起部45b、55b之情況時，使卡合突部4 7d、57d與卡合 凹部64g卡合，來抑制桿60自殻體30脫離的情況產生 (參照圖11及圖12)。 如此，非在已經卡合的狀態下抑制桿60自殼體3 0脫 離，而是藉由過度的負荷造成桿60朝脫離方向相對移動 時予以卡止，不僅可提高桿60的脫離阻止效果之可靠 性，非單純的卡止，而是藉由凹凸部（卡合突部47d與卡 合凹部64g)相互地卡合，能夠更進一步抑制桿60自殼 體30脫離。 又，在朝前方的荷重施加於開狀態的桿60之情況， 藉由卡合突起47d的前端面47b與卡合凹部64g的側面 64h，限制桿60朝前方移動，並且藉由水平面47c與圓弧 面64i，限制桿朝上方移動，藉此，能夠更進一步提高桿 60的脫離阻止效果》 該結構之桿60朝殼體30之安裝是以下述方式進行。 首先，使彈簧部47、57的前端插通於桿60的貫通孔 63，並且從彈簧部47的前端與端子臂部45的前端之間及 彈簧部5 7的前端與支承臂5 5的前端之間，即’水平面 -24- 201222990 47c與突起部45b之間及水平面57c與突起部55b之間 入凸輪部64。 然後，將桿60的寬度方向Y兩端的樞支軸61載 於殻體30的寬度方向Y兩端的軸承部35a並且將保持 件70安裝於連結壁部34f，藉此’桿60可開閉（轉動 地安裝於殼體30的桿裝設部35。 再者，在本實施形態，當桿60位於開位置時，藉 將凸輪部64朝橫方向（前後方向X )作成細長，使得 將彈簧部47、57的前端插通於貫通孔63時，即，使貫 孔63與彈簧部47、57的前端相對向的狀態時，在水平 47c、5<7C與突起部45b、55b之間相對向的凸輪部64 厚度變小。因此，當從水平面47c、57c與突起部45b 5 5b之間插入凸輪部64時，變得不需要以大的力來 入’能夠容易將凸輪部64予以插入。 其次，依據圖6〜圖10說明關於次當關閉桿60時 接頭40及保持端子50的動作。 首先，當桿60位於開位置時，如圖6所示，可動 接頭部42的彈簧部47接近殼體30的頂壁部32，但不 頂壁部32接觸。即，可動側接頭部42的彈簧部47與 壁部3 2形成爲具有間隙而分離之狀態。此時，桿60的 輪部64與彈簧部47的凸輪面47a形成爲非卡合狀態 又’雖未圖示，可動側保持部5 2的彈簧部5 7也形成爲 樣的狀態。即，可動側保持部52的彈簧部57與頂壁 32形成爲具有間隙而分離之狀態，並且桿6〇的凸輪部 插 置 扣 ) 由 當 通 面 的 、 壓 之 側 與 頂 凸 〇 同 部 -25- 64 201222990 與彈簧部57的凸輪面57a形成爲非卡合狀態。 其次，將電纜2插入至殼體30內。此時，由於接頭 40之固定側接觸部44的固定側接點部（前端）44a與可 動側接觸部46的可動側接點部（前端）46a之間的距離 D2與電纜2的厚度大致相同，故，可抑制在電纜2與接 頭40之間產生摩擦力，能將電纜2圓滑地插入至殼體30 內。又，由於保持端子50的固定側卡合突部5 4a與可動 側卡合突部5 6a之距離（一對卡合突部間的距離）D1較 電纜2的厚度更小，故，當將電纜2插入至殼體30內 時，固定側卡合突部54a及可動側卡合突部56a自電纜2 的表裏面插入到保持孔2c。藉此，藉由保持端子50，將 電纜2予以暫時保持。因此，即使在桿60位於開位置的 狀態，也可抑制電纜2脫離。再者，在本實施形態，藉由 在接頭40的寬度方向Y兩端個別設有1個保持端子50, 可極力地抑制在電纜2與保持端子50之間所產生的摩擦 力之增加，能夠極力地抑制電纜2對殻體30內之圓滑插 入作業被保持端子50所阻礙的情況產生。 又，在已將電纜2插入於殼體30內之狀態下，使桿 60朝以箭號A所示的順時鐘轉動時，接頭抵接面64d會 如圖7所示，抵接於彈簧部47的凸輪面47a，而與凸輪 面47 a滑接。且，當使桿60朝閉方向轉動時，凸輪部64 一邊使接頭抵接面64d與凸輪面4 7a滑接一邊進行轉動， 使彈簧部47彈性地撓曲變形成接頭40的彈簧部47的前 端與端子臂部45的前端之間隔相對地打開。再者，在桿 -26- 201222990 60朝閉方向轉動的途中，彈簧部47的略中間部會與頂壁 部32接觸。又，在保持端子50也進行同樣的動作，在桿 60朝閉方向轉動的途中，撓曲變形後的彈簧部57之略中 間部會與頂壁部3 2接觸。 然後’伴隨彈簧部47的撓曲變形，連結彈簧部43也 會彈性地撓曲變形。如此，藉由使彈簧部47及連結彈簧 部43撓曲’使得接頭40彈性地撓曲變形成可動側接頭部 42的可動側接觸部46與固定側接頭部41的固定側接觸 部4 4之間隔（可動側接點部4 6 a與固定側接點部4 4 a之 距離）變小。即’可動側接點部4 6 a朝固定側接點部4 4 a 方向移動。其結果，電纜2在可動側接點部46a與固定側 接點部44a壓接之狀態下，與接頭40導通連接。 此時，在保持端子50，如圖10所示，當已將彈簧部 57及連結彈簧部53撓曲時，彈性地撓曲變形成可動側保 持部5 2的可動側保持臂5 6與固定側保持部5 1的固定側 保持臂54之間隔（可動側卡合突部56a與固定側卡合突 部5 4a之距離D 1 )變小。其結果，形成爲可動側卡合突 部5 6a及固定側卡合突部54a自電纜2的表裏面側更進一 步插入到保持孔2c之狀態。即，可更進一步增大可動側 卡合突部56a及固定側卡合突部54a與保持孔2c之卡合 精度，保持端子50可穩固地保持電纜2。如此，在本實 施形態，藉由將可動側卡合突部56a及固定側卡合突部 54a自電纜2的表裏兩面側插入到保持孔2c，使得保持端 子50保持電纜2，因此，即使在電纜2的厚度參差不齊 -27- 201222990 或外力作用於電纜2之情況，電纜2也不容易脫離。即， 在本實施形態’能夠抑制電纜2自連接器1脫離。 如此，在本實施形態’將保持端子5 0的形狀作成爲 與接頭40的形狀大致相同的形狀，藉由桿60的轉動，使 得可動側卡合突部5 6 a及固定側卡合突部5 4 a之間的距離 (―對卡合突部間的距離）D1改變。即，藉由桿60的轉 動，進行可動側卡合突部56a及固定側卡合突部54a朝保 持孔2c之卡合。如此’不需要將藉由保持端子50所進行 之電纜2的保持用的操作與接頭40的導通連接個別地進 行，能夠謀求連接器1的操作性提升。 又，在本實施形態，當使桿60朝閉方向轉動，而使 彈簧部47、57的全體朝頂壁部32的方向撓曲時，在桿 60朝閉方向轉動的途中，彈簧部47、57的略中間部會與 頂壁部3 2接觸。 又，如圖1 3所示，當使桿6 0朝閉方向轉動，而使彈 簧部47的全體朝頂壁部32的方向撓曲時，若彈簧部47 不與頂壁部32接觸，則會有彈簧部47及可動側接觸部 46的撓曲所產生之應力集中於連結彈簧部43，造成連結 彈簧部43疲乏之虞產生。再者，在保持端子50，也同樣 地會有連結彈簧部53疲乏之虞產生。 但’如本實施形態，藉由在桿60朝閉方向轉動的途 中，使彈簧部47的略中間部與頂壁部32接觸，當可動側 接頭部42產生撓曲時，亦可將接頭40的撓曲所產生的應 力集中於彈簧部47與頂壁部（殼體30內壁）32接觸之 -28- 201222990 接觸部位。其結果’能夠分散施加於連結彈簧部4 3之 力，可減少應力集中於將可動側接頭部42與固定側接 部41予以連結之連結彈簧部43的局部，能夠抑制連結 簧部43疲乏。 又’藉由在桿60朝閉方向轉動的途中，使彈簧部 的略中間部與頂壁部32接觸，當可動側保持部52產生 曲時’亦可將因保持端子50的撓曲所產生之應力集中 彈簧部57與頂壁部（殼體30內壁）32接觸之接觸 位。其結果，能夠分散施加於連結彈簧部53之應力， 減少應力集中於將可動側保持部5 2與固定側保持部5 1 以連結之連結彈簧部5 3的局部，能夠抑制連結彈簧部 疲乏。 又，當進一步使桿60朝閉方向轉動時，會在彈簧 47、57的略中間部與頂壁部32接觸的狀態下，桿60 動到閉位置。即，在本實施形態，在將桿60朝閉方向 動，使可動側接點部46a與固定側接點部44a壓接於電 2之狀態下，彈簧部47的略中間部會與頂壁部32接 (參照圖8)。又，雖未圖示，保持端子50也與接頭 同樣地，在使桿60朝閉方向轉動，讓保持端子50保持 電纜2之狀態下，彈簧部57的略中間部會與頂壁部32 觸。 因此，在連接器1使用時（使桿60轉動至閉位置 將接頭40及保持端子50壓接於電纜2之狀態時），能 分散施加於連結彈簧部43、53之應力，因此’可提升 應 頭 彈 57 撓 於 部 可 予 53 部 轉 轉 纜 觸 40 著 接 9 夠 連 -29- 201222990 接器1的製品壽命。 且，在本實施形態，如圖7及圖8所示，設置於彈簧 部47、57的略中間部之階差部47e、5 7e附近的基部側會 與頂壁部32接觸（在圖7及圖8，雖顯示接頭40，但保 持端子50也相同）。即，在彈簧部47 ' 57與頂壁部32 接觸後，較階差部47e、57e更前端側之厚度薄的部分會 朝上方撓曲變形。 如此，藉由以階差部47e、57e作爲基點使彈簧部 47、57撓曲，能夠更有效率地使應力集中於彈簧部47、

Further, the angle formed by the first surface 64e and the second surface 64f (see Fig. 7) is an acute angle. Further, in the present embodiment, the angle 0 formed by the first 64e and the second surface 64f is set to be about 77 degrees. Further, between the first surface 64e and the second surface 64f, the above-described cam portion 64 rotation receiving surface 64c is provided, and the rotation receiving surface 64c forms an arcuate surface which is a small curvature. Further, in the present embodiment, the radius of curvature of the rotation receiving surface 64c is set to be about 0.05 mm. Further, in the present embodiment, when the lever 60 is in the open position, the cam portion 64 is formed to be long in the lateral direction (front-rear direction X) as shown in FIG. 6, and the dimension in the vertical direction Z is formed to be larger than the joint 40. The distance between the spring portion 47 and the sub-arm portion 45 and the interval between the spring portion 57 and the support arm 55 are smaller, that is, when the lever 60 is in the open position, the cam portion 64 and the spring portion 47 are formed in a non-contact state. Further, when the lever 60 is rotated in the closing direction (arrow A direction in Fig. 7), the upper and lower directions Z of the cam portion 64 are formed to be larger than the spring portion 47 and the terminal arm in the middle of the rotation of the cam portion 64. The spacing of the portions 45 and the spacing between the spring portions 57 and the support arms 55 are greater. That is, when the lever 60 is rotated in the closing direction, the cam portion 64 is moved by the rotation receiving surface 64c as the pivot point with the rotation receiving surface 64c as the rotation fulcrum. Turn-21 - 201222990 moves. Further, in the middle of the rotation of the lever 60 in the closing direction, the abutting surface 64d abuts against the cam faces 47a and 57a of the spring portions 47 and 57, and is in sliding contact with the cam faces 47a and 57a. Further, when the lever 60 is rotated in the closing direction, the cam portion 64 rotates the abutting surface 64d while sliding on the cam faces 47a, 57a, and the spring portions 47, 57 are elastically flexed and deformed so that the spring portion The distance between the front end of the 47 and the front end of the terminal arm portion 45 and the distance between the spring portion 57 and the support arm 55 are opened. Further, the joint spring portions 43 and 53 are elastically flexibly deformed by the deflection deformation of the spring portions 47 and 57, and the joint 40 is elastically flexed to form the movable side contact portion 46 of the movable side joint portion 42 and the fixed side joint. The interval between the fixed-side contact portions 44 of the portion 41 is reduced, and the interval between the movable-side holding arm 56 of the movable-side holding portion 52 and the fixed-side holding arm 54 of the fixed-side holding portion 51 is elastically deformed by the holding terminal 50. small. Thereby, the movable side contact portion 46a moves in the direction of the fixed side contact portion 44a, and the movable side contact portion 46a and the fixed side contact portion 44a are pressed against the cable 2, and the cable 2 and the joint 40 are Turn on the connection. Further, the movable side engagement projection 56a moves in the direction of the fixed side engagement projection 54a, and the cable 2 is held by the holding terminal 50. Thus, the cam portion 64 attaches a pressing force for crimping the joint 40 to the cable 2 to the joint 40 and attaching a pressing force for holding the cable 2 to the holding terminal 50. Further, in the present embodiment, when the lever 60 is rotated in the closing direction from the open position to the closed position, the height of the cam portion 64 gradually increases until the middle of the stroke, but when the predetermined amount of rotation is exceeded, the cam portion 64 is used. The height will gradually become lower. Further, since the convex portion -22-201222990 wheel portion 64 is pressed by the elastic recovery force of the spring portions 47, 57, the direction of action of the moment acting on the rod 6 is caused to rotate the rod 6 〇 from the open position to the closed position. Change from the opening direction to the closing direction. As described above, during the rotation of the lever 60, the pressing radius of the cam portion 64 is reduced or the acting direction of the moment acting on the lever 60 is changed from the opening direction to the closing direction, thereby giving a feeling of pressing when the lever 60 is operated. Further, when the self-closing direction is turned toward the opening direction, the same feeling of pressing can be imparted. Further, in the circular portion 64a of the cam portion 64, as shown in Figs. 6 and 11, the engagement recesses (the uneven portions that are engaged with each other) that are engaged with the engagement projections 47d and 57d are formed as shown in Figs. ) 6 4g. The engaging recessed portion 64g is a side surface 6411 that can abut against the front end faces 47b, 57b of the engaging projections 47d, 57d, and a snap projection 47 (1, 57 (1, 57 (:, 57) The abutting arc surface 64i is formed. Further, the front end faces 47b, 57b abut against the side faces 64h, and the horizontal faces 47c, 57c abut against the arcuate faces 64i' to cause the engaging projections 47d, 57d and the card In the present embodiment, the distal end faces 47b and 57b of the engaging projections 47d and 57d restrict the rod 60 toward the front, and the horizontal surfaces 47c and 57c of the engaging projections 47d and 57d are engaged. The restriction lever 60 is moved upward. Further, the front end surfaces 47b and 57b and the side surface 64h and the horizontal surfaces 47c and 57c and the circular arc surface 64i may be in surface contact with each other. Thereby, the engagement projection 47d can be further improved. In addition, in the present embodiment, the spring portions 47 and 57 and the cam portion 64 are provided with concave and convex portions that are engaged with each other (the engaging projections 47d and 57d are engaged with each other). The recessed portion -23-201222990 64g), but the engaging projections 47d and 57d and the engaging recessed portion 64g do not engage with each other during the opening and closing operation of the normal lever 60 (see Referring to Fig. 6), when the lever 60 is opened and closed, in a non-use state (a state in which the cable 2 is not inserted), or the like, the load toward the front is applied to the open lever 60, and the lever 60 is opened. Moving forward and upward (relatively moving in a direction in which the lever 60 is disengaged from the joint 40), when the protrusions 45b and 55b are slightly beyond the mountain shape, the engaging projections 47d, 57d and the engaging recess 64g are engaged. In response to the fact that the lever 60 is detached from the housing 30 (refer to FIGS. 11 and 12), the lever 60 is prevented from being disengaged from the housing 30 in a state of being engaged, but by excessive load. When the lever 60 is relatively moved in the disengaging direction, the lever 60 is locked, and the reliability of the disengagement preventing effect of the lever 60 can be improved, and the uneven portion (the engaging projection 47d and the engaging recess 64g) can be used instead of the simple locking. When the levers 60 are engaged with each other, the lever 60 can be further prevented from being detached from the housing 30. Further, when the load toward the front is applied to the lever 60 in the open state, the front end surface 47b of the engaging projection 47d and the engaging recess 64g are engaged. Side 64h, the limit bar 60 moves forward and is horizontal 47c and the circular arc surface 64i, the restriction lever is moved upward, whereby the detachment prevention effect of the lever 60 can be further improved. The attachment of the rod 60 of the structure to the casing 30 is performed in the following manner. First, the spring portion 47 is caused. The front end of the 57 is inserted into the through hole 63 of the rod 60, and is between the front end of the spring portion 47 and the front end of the terminal arm portion 45 and between the front end of the spring portion 57 and the front end of the support arm 55, that is, the 'horizontal plane' A cam portion 64 is inserted between the -24-201222990 47c and the protrusion 45b and between the horizontal surface 57c and the protrusion 55b. Then, the pivot shaft 61 at both ends in the width direction Y of the rod 60 is placed on the bearing portion 35a at both ends in the width direction Y of the casing 30 and the holder 70 is attached to the joint wall portion 34f, whereby the rod 60 can be opened and closed (rotated) Further, in the present embodiment, when the lever 60 is in the open position, the cam portion 64 is elongated in the lateral direction (forward and backward direction X) so that the spring portion 47 is moved. When the front end of the 57 is inserted into the through hole 63, that is, when the through hole 63 is opposed to the front ends of the spring portions 47 and 57, at the level 47c, 5 <7C The thickness of the cam portion 64 opposed to the protruding portions 45b and 55b becomes small. Therefore, when the cam portion 64 is inserted between the horizontal surfaces 47c, 57c and the projections 45b 5 5b, it is not necessary to insert with a large force "the cam portion 64 can be easily inserted. Next, the operation of the joint 40 and the holding terminal 50 when the lever 60 is closed will be described with reference to Figs. 6 to 10 . First, when the lever 60 is in the open position, as shown in Fig. 6, the spring portion 47 of the movable joint portion 42 approaches the top wall portion 32 of the casing 30, but the top wall portion 32 does not contact. In other words, the spring portion 47 of the movable side joint portion 42 and the wall portion 32 are formed in a state of being separated by a gap. At this time, the wheel portion 64 of the lever 60 and the cam surface 47a of the spring portion 47 are formed in a non-engaged state. Further, although not shown, the spring portion 57 of the movable-side holding portion 52 is also formed in a state similar to that. That is, the spring portion 57 of the movable-side holding portion 52 and the top wall 32 are formed in a state of being separated by a gap, and the cam portion of the rod 6〇 is inserted into the buckle) by the same side of the pressure surface and the top side of the top convex portion -25- 64 201222990 is formed in a non-engaged state with the cam surface 57a of the spring portion 57. Next, the cable 2 is inserted into the casing 30. At this time, the distance D2 between the fixed side contact portion (front end) 44a of the fixed side contact portion 44 of the joint 40 and the movable side contact portion (front end) 46a of the movable side contact portion 46 is substantially the same as the thickness of the cable 2. Therefore, it is possible to suppress the occurrence of friction between the cable 2 and the joint 40, and the cable 2 can be smoothly inserted into the casing 30. Further, since the distance between the fixed-side engagement projections 5 4a of the holding terminal 50 and the movable-side engagement projections 56a (the distance between the pair of engagement projections) D1 is smaller than the thickness of the cable 2, when When the cable 2 is inserted into the casing 30, the fixed side engagement projection 54a and the movable side engagement projection 56a are inserted into the holding hole 2c from the front and back of the cable 2. Thereby, the cable 2 is temporarily held by holding the terminal 50. Therefore, even when the lever 60 is in the open position, the cable 2 can be prevented from being detached. Further, in the present embodiment, by providing one holding terminal 50 at each end in the width direction Y of the joint 40, the increase in the frictional force generated between the cable 2 and the holding terminal 50 can be suppressed as much as possible. It is strongly suppressed that the cable 2 is prevented from being obstructed by the holding terminal 50 in the smooth insertion operation in the casing 30. Further, when the rod 60 is rotated in the clockwise direction indicated by the arrow A in a state where the cable 2 has been inserted into the casing 30, the joint abutting surface 64d abuts against the spring portion as shown in FIG. The cam surface 47a of the 47 is slidably coupled to the cam surface 47a. When the lever 60 is rotated in the closing direction, the cam portion 64 is rotated while the joint abutting surface 64d is in sliding contact with the cam surface 47a, and the spring portion 47 is elastically flexed to form the spring portion 47 of the joint 40. The front end is opened opposite to the front end of the terminal arm portion 45. Further, in the middle of the rotation of the lever -26-201222990 60 in the closing direction, the slightly intermediate portion of the spring portion 47 comes into contact with the top wall portion 32. Further, the same operation is performed on the holding terminal 50, and the middle portion of the spring portion 57 after the deflection is brought into contact with the top wall portion 32 in the middle of the rotation of the rod 60 in the closing direction. Then, the connecting spring portion 43 is elastically flexibly deformed along with the deflection of the spring portion 47. In this manner, the spring portion 47 and the connecting spring portion 43 are flexed to elastically flex the joint 40 to form the movable side contact portion 46 of the movable side joint portion 42 and the fixed side contact portion 4 of the fixed side joint portion 41. The interval (the distance between the movable side contact portion 4 6 a and the fixed side contact portion 4 4 a) becomes small. That is, the movable side contact portion 46a moves in the direction of the fixed side contact portion 4 4 a. As a result, the cable 2 is electrically connected to the joint 40 in a state where the movable side contact portion 46a is pressed against the fixed side contact portion 44a. At this time, as shown in FIG. 10, when the spring portion 57 and the connecting spring portion 53 are deflected, the movable terminal holding arm 56 and the fixed side of the movable side holding portion 52 are flexibly deformed. The interval between the fixed-side holding arms 54 of the side holding portion 51 (the distance D 1 between the movable-side engaging projections 56a and the fixed-side engaging projections 5 4a) becomes small. As a result, the movable side engagement projections 56a and the fixed side engagement projections 54a are further inserted into the holding holes 2c from the front side of the cable 2. In other words, the engagement accuracy between the movable-side engagement projection 56a and the fixed-side engagement projection 54a and the holding hole 2c can be further increased, and the holding terminal 50 can stably hold the cable 2. In this embodiment, the movable side engagement projection 56a and the fixed side engagement projection 54a are inserted into the holding hole 2c from both the front and back sides of the cable 2, so that the holding terminal 50 holds the cable 2, and therefore, even in the case The thickness of the cable 2 is uneven -27-201222990 or when an external force acts on the cable 2, the cable 2 is not easily detached. That is, in the present embodiment, it is possible to suppress the cable 2 from being detached from the connector 1. As described above, in the present embodiment, the shape of the holding terminal 50 is substantially the same as the shape of the joint 40, and the movable side engaging projection 5 6 a and the fixed side engaging projection are caused by the rotation of the lever 60. The distance between 5 4 a ("distance between the engaging projections" D1 changes. In other words, the movable side engagement projection 56a and the fixed side engagement projection 54a are engaged with the retaining hole 2c by the rotation of the lever 60. Thus, it is not necessary to individually perform the operation for holding the cable 2 by the holding terminal 50 and the conduction connection of the joint 40, and the operability of the connector 1 can be improved. Further, in the present embodiment, when the lever 60 is rotated in the closing direction and the entire spring portions 47 and 57 are deflected in the direction of the top wall portion 32, the spring portion 47 is in the middle of the rotation of the lever 60 in the closing direction. The slightly intermediate portion of 57 is in contact with the top wall portion 32. Further, as shown in FIG. 13, when the rod 60 is rotated in the closing direction and the entire spring portion 47 is deflected in the direction of the top wall portion 32, if the spring portion 47 is not in contact with the top wall portion 32, The stress generated by the deflection of the spring portion 47 and the movable side contact portion 46 is concentrated on the connection spring portion 43, and the connection spring portion 43 is caused to be tired. Further, in the holding of the terminal 50, the connection spring portion 53 is also fatigued. However, as in the present embodiment, the slightly intermediate portion of the spring portion 47 is brought into contact with the top wall portion 32 while the rod 60 is being rotated in the closing direction, and when the movable side joint portion 42 is deflected, the joint 40 can be used. The stress generated by the deflection is concentrated on the contact portion of the spring portion 47 in contact with the top wall portion (the inner wall of the casing 30) 32 at -28-201222990. As a result, the force applied to the connection spring portion 43 can be dispersed, and the stress can be concentrated on a portion of the connection spring portion 43 that connects the movable side joint portion 42 and the fixed side joint portion 41, and the connection spring portion 43 can be prevented from being fatigued. Further, by the middle of the rotation of the rod 60 in the closing direction, the slightly intermediate portion of the spring portion is brought into contact with the top wall portion 32, and when the movable side holding portion 52 generates a curve, it is also caused by the deflection of the holding terminal 50. The stress concentration spring portion 57 is in contact with the top wall portion (the inner wall of the casing 30) 32. As a result, the stress applied to the connection spring portion 53 can be dispersed, and the stress concentration can be concentrated on the portion of the connection spring portion 53 that connects the movable-side holding portion 5 2 and the fixed-side holding portion 5 1 , and the connection spring portion can be prevented from being fatigued. Further, when the lever 60 is further rotated in the closing direction, the lever 60 is moved to the closed position in a state where the slightly intermediate portion of the springs 47, 57 is in contact with the top wall portion 32. In other words, in the present embodiment, when the lever 60 is moved in the closing direction and the movable-side contact portion 46a and the fixed-side contact portion 44a are pressed against the electric 2, the slightly intermediate portion of the spring portion 47 and the top wall are provided. The part 32 is connected (refer to Fig. 8). Further, although not shown, the holding terminal 50 is also rotated in the closing direction in the same manner as the joint, and the holding portion 50 is held by the cable 2, and the slightly intermediate portion of the spring portion 57 is in contact with the top wall portion 32. . Therefore, when the connector 1 is used (when the lever 60 is rotated to the closed position and the joint 40 and the holding terminal 50 are crimped to the cable 2), the stress applied to the connecting spring portions 43, 53 can be dispersed, so that it can be lifted. Should be the head of the bullet 57 can be flexed to the section can be 53 parts of the turn cable touch 40 reach 9 enough to connect -29- 201222990 connector 1 product life. Further, in the present embodiment, as shown in Figs. 7 and 8, the base portion side in the vicinity of the step portions 47e and 57e provided in the slightly intermediate portion of the spring portions 47, 57 is in contact with the top wall portion 32 (in Fig. 7). As shown in Fig. 8, although the joint 40 is shown, the holding terminal 50 is also the same. In other words, after the spring portion 47' 57 comes into contact with the top wall portion 32, the portion of the step portion 47e, 57e which is thinner at the front end side is flexibly deformed upward. By bending the spring portions 47 and 57 with the step portions 47e and 57e as the base points, the stress can be more efficiently concentrated on the spring portions 47 and 57. Therefore, it is possible to further suppress the joint spring portions 43, 53 from being fatigued. As described in detail above, in the present embodiment, the first surface 64e of the vertical bottom portion 37 (the bottom wall portion of the rod mounting portion 35) and the rod 60 are abutted in the open state of the rod 60. The angle 0 formed by the second surface 64f that abuts against the bottom surface 37d (the bottom wall portion of the rod mounting portion 35) in the closed state is formed at an acute angle, and the rotation receiving surface (rotation receiving portion) 64c of the cam portion 64 is formed. Therefore, the width of the cam portion 64 can be made narrower. Therefore, it becomes easy to rotate the rod 60, and when the direction of action of the moment acting on the rod 60 exceeds a predetermined amount of rotation from the opening direction to the closing direction, the rod 60 can be more rapidly rotated in the closing direction than in the related art. And increase the feeling of pressing of the lever operation. Further, in the present embodiment, since the rotation receiving surface (rotation receiving portion) 64c is formed in an arc shape in which the first surface 64e and the second surface 64f are coupled to each other, the rod operation can be performed more smoothly, and the rod can be suppressed. The operation causes the rotation receiving surface (rotation receiving portion) 64c to be cut. -30-201222990 The preferred embodiment of the present invention has been described. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the specifications (shape, size, arrangement, and the like) of the casing, the rod, the cam portion, and other details can be appropriately changed.
