The cable 2 is inserted. Fig. 8 is located on the side of the shell) * □ ) 31 and the front portion of the outer portion 34a of the region 34 in Fig. 1 is formed, and the rod mounting portion 35 is opened upward and forward in 201223013. In this lever mounting portion 35, the lever 60 is rotatably mounted. Further, at both end portions of the rod mounting portion 35 in the width direction Y, bearing portions 35a that open upward and forward are formed, and the bearing portions 35a face each other in the width direction Y of the casing 30. In the present embodiment, the bearing portion 35a is formed by the inner side rear surface 34b of the connecting wall portion 34f connecting the side wall portion 34 and the front side wall portion 34a, and the both ends in the width direction γ of the bottom wall portion 34e as shown in Figs. 1 and 4 . The bottom surface 34c and the inner side surface 34d of the front side wall portion 34a are defined. Further, the rod 60 is a plate-like member that can be housed in the rod mounting portion 35 of the casing 30, and the rod 60 is also formed of an insulating material such as synthetic resin. Further, as shown in Fig. 1 and Fig. 2, the base end side (one end side of the rod 60) on both end faces of the rod 60 in the width direction Y is formed with a pivot shaft 6 1 and a main body of the rod 60 ( The other end side of the lever 60 is an operation portion 62 for opening and closing the lever 60 (rotation operation). In the present embodiment, from the front side of the casing 30 (opposite to the cable receiving portion 31), the pivot shafts 61 at both ends in the width direction Y of the rod 60 are placed on the bearing portions 35a at both ends in the width direction Y of the casing 30 and The holding fastener 70 is attached to the connecting wall portion (housing) 34f, whereby the rod 60 can be opened and closed (rotated) to the rod mounting portion 35 of the casing 30 (refer to Figs. 1 and 4). As shown in FIG. 4, the fastener 70 is formed of a thin metal plate and has a body portion 71 extending in the front-rear direction. Further, an insertion piece (insertion fixing portion) 71a' is extended downward from the front portion of the main body portion 71-8-201223013, and a support piece 71b' is extended from the lower portion of the rear portion of the main body portion 71 in front of the main body portion 71, and is bent. A pivotal shaft covering portion 71c having a claw shape that is convex upward is extended toward the front. Further, in order to cover the upper and the front sides of the pivot shaft 61 (the one end side in the insertion/removal direction of the cable 2), the retaining fastener 70 is attached to the connecting wall portions 34f and 34f. Specifically, in the connecting wall portions 3 4f and 3 4f, an insertion hole (recessed portion 34g) into which the insertion piece (insertion fixing portion) 71a is inserted is formed by pressing the insertion piece (insertion fixing portion) 71a from above. The insertion hole (recess) 34g is inserted (inserted), and the holding fastener 70 is attached to the connection wall parts 3 4f and 34f. In the present embodiment, the rear wall portion 34h of the connecting wall portion 34f is inserted into the concave portion 71d formed between the insertion piece (insertion fixing portion) 71a and the support piece 71b, and the insertion piece (insertion fixing portion) 71a and the support are inserted. The sheet 71b holds the rear wall portion 34h. Further, in the insertion piece (insertion fixing portion) 71a, projections 71e, 71e are provided at both ends in the front-rear direction. Further, by holding the projections 71e and 71e into the inner faces of the insertion holes 34g (the front face of the rear wall portion 34h and the rear of the front wall portion 34i), the fasteners 70 are stuck. The connection wall portions 34f, 34f are stopped. As described above, in the present embodiment, the retaining fastener 70 can be prevented from being detached by sandwiching the rear wall portion 34h with the insertion piece (insertion fixing portion) 71a and the support piece 71b. Further, by pressing the projections 71e and 71e into the inner faces of the insertion holes 34g, respectively, when the upward load 201223013 is generated in the pivot shaft covering portion 71c, the holding fastener 70 can be prevented from being detached. Further, in the present embodiment, as shown in Figs. 4 and 5, by attaching the holding fastener 70 to the connecting wall portions 34f and 34f, the outer circumference of the pivot shaft 61 is pivotally supported by the shaft covering portion 71c and the inner front surface 3 Covered by 4b and bottom surface 3 4c. Therefore, the upward and forward movement of the pivot shaft 61 is restricted by the pivot shaft covering portion 71c, the rearward movement is restricted by the inner front surface 34b, and the downward movement is restricted by the bottom surface 34c. In other words, when the pivotal shaft covering portion 71c generates a load toward the front, the pivot shaft 61 moves toward the upper side or the front side of the bearing portion 35a (one end side in the cable insertion/removal direction), by holding the fastener 70. By restricting the movement, the rod 60 can be prevented from being detached from the casing 30, and even if the rod 60 is detached from the joint 40, the movement of the pivot shaft 61 in the front-rear direction and the up-and-down direction is restricted by holding the fastener 70 and the casing 30. Therefore, the lever 60 can be restrained from being detached from the housing 30. In this way, in the present k form, it is not necessary to restrain the rod from being detached from the housing by engaging the rod with the retaining fastener and engaging the joint, and the rod 60 can be restrained from the housing 30 only by the retaining fastener 70. Get rid of. Further, in the present embodiment, when the retaining fastener 70 is attached to the connecting wall portions 34f, 34f by bending the pivot shaft covering portion 71c with a radius of curvature larger than the diameter of the pivot shaft 61, A gap is formed between the pivot shaft covering portion 71c and the pivot shaft 61. In other words, in the present embodiment, the holding fastener 70 is attached to the connecting wall portions 34f and 34f so that the pivot shaft covering portion 71c can cover the upper side and the front side of the pivot shaft 61 in a non-contact state (one end side of the cable 2 in the insertion/removal direction). ). Therefore, it is possible to suppress the rotation of the pivot shaft 61 from being blocked. - 201223013 The situation arises that the pivot shaft 61 can be smoothly rotated. As a result, it is not necessary to perform high-precision dimensional management such as cutting processing for ensuring the rotation of the pivot shaft 61. Further, by covering the pivot shaft 61 in a non-contact state, the pivot shaft 61 is rotatably and slidably received in the bearing portion 35a. Further, in the present embodiment, the lever 60 is attached to the casing 30° so as to be rotatable from the open position shown in Fig. 6 to the closed position shown in Fig. 8 as described above, and when the lever 60 is in the open position, The lever 60 is raised from the lever mounting portion 35 of the housing 30 in the standing position, and the front side of the lever mounting portion 35 is slightly opened to the upper side of the housing 30 (see FIG. 6). At this time, the cable 2 can be inserted into the cable receiving portion 31 of the casing 30. Further, on the one end side of the operation portion 62 of the lever 60 (the rear side in the state where the lever 60 is in the open position), the stepped portion 62a forms a step with the flat portion 62b, and when the lever 60 is rotated in the opening direction, The flat portion 62b abuts against the upper end portion of the inner rear surface 34b of the connecting wall portion 34f. That is, in the present embodiment, the rotation of the rod 60 in the opening direction is restricted by the upper end portion of the inner rear surface 34b of the connecting wall portion 34f. Further, when the lever 60 is in the closed position, the lever 60 is placed in the lever mounting portion 35 of the casing 30 in a slightly horizontal posture, and the cable 2 inserted into the cable receiving portion 31 is held by the joint 40. (Refer to Figure 8). The joint 40 is formed in plural in the width direction γ of the casing 30, and the joint 40 is formed by press working a thin metal. Further, the joint 40 is inserted into the casing 30 from the front and fixedly held (see -11 - 201223013, see Figs. 6 to 8). In the present embodiment, the casing 30 accommodates a plurality of the receiving portions 36 so as to penetrate in the front-rear direction X, and the respective accommodating portions 36 are separated by the vertical walls extending in the front-rear direction X. In other words, in the present embodiment, each of the accommodating portions 36 is formed by the bottom wall portion 33 and the vertical wall portion 37, and the accommodating portion 36 that is formed in the front-rear direction is inserted into the joint 40 from the front.

Further, the deep wall surface 37b 2 of the deep portion (the front side in the front-rear direction) of 37a moves toward the front (insertion direction). Further, the front portion of the vertical wall portion 37 is formed in a substantially double-shaped shape by cutting the L-shaped angle of view in the front-rear direction X. The front side surface 37c of the portion 37 and the bottom surface 37d are spaced by the rod mounting portion.

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37d (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 )64 c;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作成爲全開狀 態時，抵接於縱壁部3 7的底面3 7d (桿裝設部3 5的底壁 部）之第1面64e ;和當將桿60作成爲全閉狀態時，抵 接於縱壁部37的底面3 7d (桿裝設部35的底壁部）之第 2面64f。又’第1面64e與第2面64f所成的角度0 ( 參照圖7)呈銳角。再者，在本實施形態，將第1面64e 與第2面64f所成的角度0設定成大約77度。又，在第 1面64e與第2面64f之間’設有上述的凸輪部64的轉動 承受面64c，此轉動承受面64c形成作爲小的曲率半徑之 圓弧面。再者，在本實施形態，將轉動承受面64c的曲率 -19- 201223013 半徑設定成爲大約〇.〇5mm。 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，形成爲朝横方向（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5 7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的轉 ，凸輪部64以轉動承受面64c作爲轉動支點進行轉動 又，在桿60朝閉方向轉動的途中，抵接面64d抵接於 簧部47、57的凸輪面47a、57a，而與凸輪面47a、57a 接。且，當使桿60朝閉方向轉動時，凸輪部64係使抵 面64d —邊滑接於凸輪面47a、57a —邊轉動，使彈簧 47、57彈性地撓曲變形，使得彈簧部47的前端與端子 部45的前端之間隔及彈簧部57與支承臂55之間隔相 地打開。又，藉由伴隨彈簧部47、5 7的撓曲變形，連 彈簧部43、53彈性地撓曲變形，接頭40彈性地撓曲變 成可動側接頭部42的可動側接觸部46與固定側接頭 41的固定側接觸部44之間隔變小，保持端子5 0彈性 撓曲變形成可動側保持部52的可動側保持臂56與固定 置 細 端 〇 57 動 方 彈 動 〇 彈 滑 接 部 臂 對 結 形 部 地 側 -20- 201223013 保持部5 1的固定側保持臂5 4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56a 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 輪部64使得作用於桿60之力矩的作用方向會在使桿60 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。 且，在本實施形態，如上述，形成凸輪部纟4的轉動 承受面（旋轉承受部）64c ’使得在桿60的開狀態下抵接 於縱壁部37的底面3 7d (桿裝設部35的底壁部）之第！ 面64e和在桿60的閉狀態下抵接於縱壁部37的底面3 7d (桿裝設部35的底壁部）之第2面64f所成的角度0形 成爲銳角。因此，可將凸輪部64寬度縮得更窄，能使桿 -21 - 201223013 60越容易旋轉。如此，藉由使桿60容易旋轉，當超過預 定的轉動量而作用於桿60的力矩之作用方向從開方向朝 閉方向改變時，比起以往能夠使桿60迅速地朝閉方向轉 動’進而可增大桿操作的按壓感。 又’藉由將轉動承受面（旋轉承受部）64c形成爲結 合第1面64e與第2面64f之圓弧狀，能夠更圓滑地進行 桿操作，並且能夠抑制因桿操作造成轉動承受面（旋轉承 受部）64c被切削之情況產生。 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4 7d、57d之卡 合凹部（相互地卡合的凹凸部）64g。此卡合凹部64g是 由可與卡合突部47d、5 7d的前端面47b、57b抵接之側面 64h、和可與卡合突部47d、57d的水平面47c、57c抵接 之圓弧面64i所形成。又，藉由前端面47b、57b與側面 64h抵接，並且水平面47c、57c與圓弧面64 i抵接，使卡 合突部47d、57d與卡合凹部64g相互卡合（參照圖12 ) 〇 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、5 7c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 -22- 201223013 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4 7d、5 7d與卡合凹部 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47d、57d與卡合 凹部64g卡合，來抑制桿60自殼體30脫離的情況產生（ 參照圖1 1及圖12 )❶ 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。 -23- 201223013 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57的前端與支承臂55的前端之間，即，水平面 47c與突起部45b之間及水平面57c與突起部55b之間插 入凸輪部64。 然後，將桿60的寬度方向Y兩端的樞支軸61載置 於殼體30的寬度方向Y兩端的軸承部35a並且將保持扣 件70安裝於連結壁部34f，藉此，桿60可開閉（轉動） 地安裝於殻體30的桿裝設部35。 再者，在本實施形態，當桿60位於開位置時，藉由 將凸輪部64朝横方向（前後方向X)作成細長，使得當 將彈簧部47、57的前端插通於貫通孔63時，即，使貫通 孔63與彈簧部47、57的前端相對向的狀態時，在水平面 47c、57c與突起部45b' 55b之間相對向的凸輪部64的 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壓入 ，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時之 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，可動側 接頭部42的彈簧部47接近殻體30的頂壁部32，但不與 頂壁部32接觸。即，可動側接頭部42的彈簧部47與頂 壁部32形成爲具有間隙而分離之狀態。此時，桿60的凸 輪部64與彈簧部47的凸輪面47a形成爲非卡合狀態》又 -24- 201223013 ，雖未圖示，可動側保持部52的彈簧部57也形成爲同樣 的狀態。即，可動側保持部52的彈簧部57與頂壁部32 形成爲具有間隙而分離之狀態，並且桿60的凸輪部64與 彈簧部5 7的凸輪面5 7a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圓滑地插入至殻體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56a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。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對殼體3 0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插入於殻體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47a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47a滑接一邊進行轉動， -25- 201223013 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 6〇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 6〇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32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4 1的固定側接觸 部44之間隔（可動側接點部46a與固定側接點部44a之 距離）變小。即，可動側接點部46a朝固定側接點部44a 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（可動側卡合突部56a與固定側卡合突 部54a之距離D1 )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2 c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，將保持端子5 0的形狀作成爲 -26- 201223013 與接頭40的形狀大致相同的形狀，藉由桿60的轉動，使

又，如圖13所示，當使桿60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（殻體30內壁）32接觸之 接觸部位。其結果，能夠分散施加於連結彈簧部4 3之應 力’可減少應力集中於將可動側接頭部42與固定側接頭 部41予以連結之連結彈簧部43的局部，能夠抑制連結彈 簧部43疲乏。 又’藉由在桿60朝閉方向轉動的途中，使彈簧部57 201223013 的略中間部與頂壁部32接觸，當可動側保持部52產生撓 曲時，亦可將因保持端子50的撓曲所產生之應力集中於 彈簧部57與頂壁部（殼體30內壁）32接觸之接觸部位 。其結果，能夠分散施加於連結彈簧部53之應力，可減 少應力集中於將可動側保持部5 2與固定側保持部5 1予以 連結之連結彈簧部5 3的局部，能夠抑制連結彈簧部5 3疲 乏。 又，當進一步使桿60朝閉方向轉動時，會在彈簧部 47、57的略中間部與頂壁部32接觸的狀態下，桿60轉 動到閉位置。即，在本實施形態，在將桿60朝閉方向轉 動’使可動側接點部46a與固定側接點部44a壓接於電纜 2之狀態下，彈簧部47的略中間部會與頂壁部32接觸（ 參照圖8)。又’雖未圖示，保持端子50也與接頭40同 樣地，在使桿60朝閉方向轉動，讓保持端子50保持著電 纜2之狀態下，彈簧部5 7的略中間部會與頂壁部3 2接觸 〇 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），能夠 分散施加於連結彈簧部43、53之應力，因此，可提升連 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、57e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 -28- 201223013 接觸後，較階差部47e、5 7e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、57 。因此，能夠更進一步抑制連結彈簧部43、53疲乏。 如以上所說明，在本實施形態，在電纜2設置保持孔 2c，並且將具有自電纜2的表裏面插入並卡合之可動側卡 合突部5 6a及固定側卡合突部54a ( —對卡合突部）的保 持端子50設置於殼體30。因此，保持端子50的可動側 卡合突部56a及固定側卡合突部54a (—對卡合突部）自 表裏面插入到電纜2的保持孔2c並卡合。因此，即使在 電纜2的厚度參差不齊或外力作用於電纜2之情況，也能 夠作成使電纜2不易脫離。即若依據，本實施形態，能夠 抑制電纜2自連接器1脫離。 又，在本實施形態，將保持端子50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56a與固定側卡合突部54a之間的距離（ 一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。因此，不需要個別地進行藉由保持端子50 所進行之電纜2的保持用的操作與接頭40的導通連接， 可提升連接器1的操作性。 又，在本實施形態，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 -29- 201223013 5 6a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46a與導體2b接觸前， 能使保持端子50的可動側卡合突部56a卡合於保持孔2c 。因此，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之位置偏移。 又，在本實施形態，將保持端子50的固定側卡合突 部5 4a與可動側卡合突部56a之距離D1設定成較電纜2 的厚度更小。又，當將電纜2插入到殻體30內時，固定 側卡合突部54a及可動側卡合突部56a (―對卡合突部） 自電纜2的表裏面被插入到保持孔2c，藉由保持端子50 ，將電纜2予以暫時保持。因此，即使爲桿60位於開位 置的狀態，也能抑制電纜2脫離的情況產生，因此，當進 行桿60的開閉操作時，能夠更確實地抑制電纜2位移。 以上，說明了關於本發明的理想實施形態，但本發明 不限於前述實施形態，可進行各種變更。 例如，亦可爲下述結構，即，將保持端子連結於與桿 不同之其他操作部材，藉由與桿操作不同的操作來與保持

Further, in the present embodiment, the radius of the curvature -19 - 201223013 of the rotation receiving surface 64c is set to about 〇.〇5 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 rotated by the rotation receiving surface 64c as a pivot point with the rotation of the lever 60, and the abutting surface 64d abuts while the lever 60 is rotated in the closing direction. The cam faces 47a and 57a of the spring portions 47 and 57 are connected to the cam faces 47a and 57a. Further, when the lever 60 is rotated in the closing direction, the cam portion 64 rotates while the abutting surface 64d is slidably engaged with the cam faces 47a, 57a, so that the springs 47, 57 are elastically flexed and deformed, so that the spring portion 47 is The distance between the front end and the front end of the terminal portion 45 and the opening of the spring portion 57 and the support arm 55 are opened. Further, the spring portions 43 and 53 are elastically flexibly deformed by the flexural deformation of the spring portions 47 and 57, and the joint 40 is elastically flexed to become the movable side contact portion 46 and the fixed side joint of the movable side joint portion 42. The interval between the fixed side contact portions 44 of the 41 is reduced, and the movable side holding arm 56 and the fixed thin end 〇 57 of the movable side holding portion 52 are elastically flexed to form the movable side holding portion 52. The side of the knot portion -20 - 201223013 The interval between the fixed side holding arms 5 4 of the holding portion 5 1 becomes small. Thereby, the movable side contact portion 46a is moved 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 cam portion 64 is pressed by the elastic restoring force of the spring portions 47, 57, the direction of action of the moment acting on the lever 60 changes from the opening direction to the closing direction while the lever 60 is rotated from the open position to the closed position. . As described above, during the rotation of the lever 60, the pressing sensation is given to the operation of the lever 60 by reducing the rotational radius of the cam portion 64 or changing the acting direction of the moment acting on the lever 60 from the opening direction to the closing direction. In the present embodiment, as described above, the rotation receiving surface (rotation receiving portion) 64c' of the cam portion 纟4 is formed so as to abut against the bottom surface 37d of the vertical wall portion 37 in the open state of the rod 60 (the rod mounting portion) The bottom of the 35) The surface 64e and the second surface 64f which abuts against the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the rod mounting portion 35) in the closed state of the rod 60 form an angle 0 which is an acute angle. Therefore, the width of the cam portion 64 can be narrowed to be narrower, and the rod -21 - 201223013 60 can be rotated more easily. As described above, when the lever 60 is easily rotated, when the direction of action of the moment acting on the lever 60 exceeds a predetermined amount of rotation from the opening direction to the closing direction, the lever 60 can be quickly rotated in the closing direction. The feeling of pressing of the lever operation can be increased. In addition, by forming the rotation receiving surface (rotation receiving portion) 64c in an arc shape in which the first surface 64e and the second surface 64f are joined, the rod operation can be performed more smoothly, and the rotation receiving surface due to the lever operation can be suppressed ( The rotation receiving portion 64c is cut. 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 engaging recessed portions that are engaged with the engaging projections 47d and 57d are formed (the concave and convex portions are engaged with each other). Department) 64g. The engaging recessed portion 64g is a side surface 64h that can abut against the front end faces 47b and 57b of the engaging projections 47d and 57d, and a circular arc surface that can abut against the horizontal faces 47c and 57c of the engaging projections 47d and 57d. Formed by 64i. Moreover, the front end surfaces 47b and 57b are in contact with the side surface 64h, and the horizontal surfaces 47c and 57c are in contact with the circular arc surface 64i, and the engagement projections 47d and 57d and the engagement recessed portion 64g are engaged with each other (refer to FIG. 12). In other words, in the present embodiment, the distal end faces 47b and 57b of the engaging projections 47d and 57d restrict the rod 60 from facing forward, and the horizontal faces 47c and 57c of the engaging projections 47d and 57d restrict the lever 60 from moving upward. Further, the front end faces 47b and 57b and the side faces 64h and the horizontal faces 47c and 57c and the arcuate faces 64i may be formed in surface contact with each other. Thereby, the engagement accuracy of the engagement projections -22-201223013 47d, 57d and the engagement recesses 64g can be further improved. Further, in the present embodiment, the spring portions 47 and 57 and the cam portion 64 are provided with concave and convex portions (the engagement projections 47d and 57d and the engagement recesses 64g) that are engaged with each other. However, the engagement projections 47d are provided. The 57d and the engagement recesses 64g are not engaged with each other during the opening and closing operation of the normal lever 60 (see FIG. 6). Further, when the lever 60 is opened and closed, the non-use state (the state in which the cable 2 is not inserted), or the like, the load toward the front is applied to the lever 60 in the open state, and the lever 60 is opened toward the front and upward. When moving (relatively moving in the 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 and 57d are engaged with the engaging recess 64g to restrain the lever 60. The case where the housing 30 is detached is produced (refer to FIGS. 11 and 12). Thus, the lever 60 is detached from the housing 30 without being engaged, but the lever 60 is disengaged by excessive load. When the direction is relatively moved, the card is locked, and the reliability of the detachment preventing effect of the lever 60 can be improved, and the uneven portion (the engaging projection 47d and the engaging recess 64g) can be engaged with each other without being simply locked. 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 side surface 64h of the engaging recess 64g restrict the lever 60 from moving forward, and by the horizontal surface 47c and the circle The curved surface 64i moves the restriction rod upward, whereby the effect of the detachment prevention of the rod 60 can be further improved. Mounting of the rod 60 of the structure toward the housing 30 is performed in the following manner. -23-201223013 First, the front ends of the spring portions 47, 57 are inserted into the through holes 63 of the rod 60, and between the front end of the spring portion 47 and the front end of the terminal arm portion 45 and the front end of the spring portion 57 and the support arm 55 The cam portion 64 is inserted between the front ends, that is, between the horizontal surface 47c and the protruding portion 45b and between the horizontal surface 57c and the protruding portion 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 holding fastener 70 is attached to the joint wall portion 34f, whereby the rod 60 can be opened and closed. (rotated) is attached to the rod mounting portion 35 of the housing 30. Further, in the present embodiment, when the lever 60 is in the open position, the cam portion 64 is elongated in the lateral direction (the front-rear direction X) so that the front ends of the spring portions 47, 57 are inserted through the through holes 63. In other words, when the through hole 63 is opposed to the distal ends of the spring portions 47 and 57, the thickness of the cam portion 64 that faces between the horizontal surfaces 47c and 57c and the protruding portion 45b' 55b becomes small. Therefore, when the cam portion 64 is inserted between the horizontal surfaces 47c and 57c and the projections 45b and 55b, it is not necessary to press it with a large force, and 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 temporarily 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 side joint portion 42 approaches the top wall portion 32 of the casing 30, but does not come into contact with the top wall portion 32. In other words, the spring portion 47 of the movable side joint portion 42 and the top wall portion 32 are formed in a state of being separated by a gap. At this time, the cam portion 64 of the lever 60 and the cam surface 47a of the spring portion 47 are formed in a non-engaged state" -24 - 201223013, and although not shown, the spring portion 57 of the movable side holding portion 52 is also formed in the same state. . In other words, the spring portion 57 of the movable-side holding portion 52 and the top wall portion 32 are formed to have a gap and are separated, and the cam portion 64 of the lever 60 and the cam surface 57a of the spring portion 57 are formed in a non-engaged state. 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 the cable is used When 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. Further, in the present embodiment, by providing one holding terminal 50 at each end in the width direction Y of the joint 40, it is possible to suppress the increase in the frictional force generated between the cable 2 and the holding terminal 50 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 slider 47 is slidably coupled to the cam surface 47a. When the lever 60 is rotated in the closing direction, the cam portion 64 rotates while the joint abutting surface 64d is in sliding contact with the cam surface 47a, and -25-201223013 elastically bends the spring portion 47 to form a spring of the joint 40. The front end of the portion 47 is opened opposite to the interval between the tips of the terminal arm portions 45. Further, in the middle of the rotation of the rod 6〇 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 6〇 in the closing direction. Then, the connecting spring portion 43 is elastically flexibly deformed in accordance with the deflection deformation of the spring portion 47. By bending the spring portion 47 and the connecting spring portion 43, 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 contact portion 44 of the fixed side joint portion 41. The interval (the distance between the movable side contact portion 46a and the fixed side contact portion 44a) becomes small. In other words, the movable side contact portion 46a moves in the direction of the fixed side contact portion 44a. 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, when the terminal 50 is held, as shown in FIG. 10, when the spring portion 57 and the connecting spring portion 53 are deflected, the movable side holding arm 56 elastically deformed to form the movable side holding portion 52 is held by the fixed side. The interval between the fixed-side holding arms 54 of the portion 51 (the distance D1 between the movable-side engaging projections 56a and the fixed-side engaging projections 54a) 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. As described above, in the present embodiment, the shape of the holding terminal 50 is substantially the same as the shape of the joint -26-201223013, and the movable side engaging projection 56a and the fixed side are engaged by the rotation of the lever 60. The distance between the projections 54a (the distance between the pair of 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. 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. A slight 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, the spring is When the 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 where the spring portion 47 comes into contact with the top wall portion (the inner wall of the casing 30) 32. As a result, the stress applied to the connecting spring portion 43 can be dispersed to reduce the stress concentration on the portion of the connecting 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, when the lever 60 is rotated in the closing direction, the slightly intermediate portion of the spring portion 57201223013 is brought into contact with the top wall portion 32. When the movable side holding portion 52 is deflected, the holding terminal 50 can be flexed. The stress generated by the curvature is concentrated on the contact portion where the spring portion 57 comes into 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 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 5 can be suppressed. 3 tired. Further, when the lever 60 is further rotated in the closing direction, the lever 60 is rotated to the closed position in a state where the slightly intermediate portion of the spring portions 47, 57 is in contact with the top wall portion 32. In other words, in the present embodiment, when the lever 60 is rotated in the closing direction, the movable side contact portion 46a and the fixed side contact portion 44a are pressed against the cable 2, and the slightly intermediate portion of the spring portion 47 is formed with the top wall. The portion 32 is in contact (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 40, and the holding portion 50 is held by the cable 2, and the slightly intermediate portion of the spring portion 57 is connected to the top wall. Therefore, when the connector 1 is in contact with the connector 1 (when the lever 60 is rotated to the closed position and the joint 40 and the holding terminal 50 are pressed against the cable 2), the coupling can be applied to the connecting spring portions 43, 53. The stress, therefore, can increase the life of the product of the connector 1. 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 at the slightly intermediate portions of the spring portions 47 and 57 is in contact with the top wall portion 32 (in FIG. 7 and In Fig. 8, although the joint 40 is shown, the holding terminal 50 is also the same. In other words, after the spring portions 47, 57 are in contact with the top wall portions 32-28 to 201223013, the portions of the step portions 47e and 57e which are thinner at the front end side are 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 effectively 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 above, in the present embodiment, the holding hole 2c is provided in the cable 2, and the movable side engaging projection portion 56a and the fixed side engaging projection portion 54a are inserted and engaged from the front surface of the cable 2. The holding terminal 50 of the engaging projection is provided in the casing 30. Therefore, the movable side engagement projection 56a and the fixed side engagement projection 54a (the pair of engagement projections) of the holding terminal 50 are inserted into the holding hole 2c of the cable 2 from the front surface and engaged. Therefore, even in the case where the thickness of the cable 2 is uneven or an external force acts on the cable 2, it is possible to make the cable 2 difficult to be detached. In other words, according to the present embodiment, it is possible to suppress the cable 2 from being detached from the connector 1. Further, in the present embodiment, the shape of the holding terminal 50 is substantially the same as the shape of the joint 40, and the rotation of the rod 60 causes the movable side engagement projection 56a and the fixed side engagement projection 54a. The distance (distance between a pair of engaging projections) D1 changes. In other words, the engagement between the movable side engagement projection 56a and the fixed side engagement projection 54a toward the holding hole 2c is performed by the rotation of the lever 60. Therefore, the operability of the connector 1 can be improved without separately performing the conduction connection between the operation of holding the cable 2 by the holding terminal 50 and the joint 40. Further, in the present embodiment, at least when the lever 60 is at the open position, the distance D1 between the fixed-side engaging projection 54a of the holding terminal 50 and the movable-side engaging projection -29-201223013 5 6a is set to be smaller than the joint 40. The distance D2 between the fixed side contact portion (front end) 44a of the fixed side contact portion 44 and the movable side contact portion (front end) 46a of the movable side contact portion 46 is shorter. Therefore, when the connecting spring portion 53 of the holding terminal 50 and the connecting spring portion 43 of the joint 40 are each bent, the movable side contact portion 46a of the joint 40 can be engaged with the movable side before the movable side contact portion 46a comes into contact with the conductor 2b. The projection 56a is engaged with the holding hole 2c. Therefore, when the movable side contact portion 46a of the joint 40 is brought into contact with the conductor 2b, the positional deviation of the cable 2 can be more reliably suppressed. Further, in the present embodiment, the distance D1 between the fixed-side engaging projections 5 4a of the holding terminal 50 and the movable-side engaging projections 56a is set to be smaller than the thickness of the cable 2. Further, when the cable 2 is inserted into the casing 30, the fixed-side engagement projection 54a and the movable-side engagement projection 56a (the "engagement engagement projection") are inserted into the holding hole 2c from the front surface of the cable 2, The cable 2 is temporarily held by holding the terminal 50. Therefore, even when the lever 60 is in the open position, the occurrence of the disconnection of the cable 2 can be suppressed. Therefore, when the opening and closing operation of the lever 60 is performed, the displacement of the cable 2 can be more reliably suppressed. The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made. For example, a configuration may be adopted in which the holding terminal is coupled to another operating member different from the lever, and is engaged with the holding hole by an operation different from the lever operation. Further, the shape of the holding terminal is not limited to that shown in the above embodiment, and can be made into various shapes. Further, the specifications (shape, size, size, size, size, size, size, size, size, etc.) of the casing, the rod, the cam portion, and other details may be appropriately changed.
