The portion of the spring portion of 201,223,012 -6- contactable to the inner wall of the housing "[Embodiment] Hereinafter, morphology described embodiment of the present invention in detail with reference to the drawings. Hereinafter, the cable insertion/removal direction is regarded as the front-rear direction X, and the longitudinal direction of the casing (the direction in which the contacts are arranged in parallel: the direction orthogonal to the cable insertion and removal directions and the thickness direction) is regarded as the width direction Y, and The thickness direction of the casing (the thickness direction of the inserted cable) will be described as the vertical direction Z. Further, the direction in which the cable is moved when the cable is inserted is defined as the front side, the direction in which the cable is moved when the cable is detached is defined as the rear side, and the connector is disposed such that the lever attached to the casing is located at the upper portion. The upper side of the state is defined as the upper side and the vertical direction is defined. As shown in Fig. 1, the connector 1 of the present embodiment includes an insulating casing 30 having a sheet-like cable 2 having a surface and a back surface such as an FPC or an FFC. In the insertion end portion 2a of the sheet-like cable 2 (see FIGS. 3 and 10), a plurality of conductors 2b are exposed at a predetermined equal interval in the width direction Y, and at both ends in the width direction Y of the conductor 2b. A holding hole 2c is formed. Then, inside the casing 30, a plurality of electrically conductive contacts 40' that are electrically connected to the conductors 2b of the cable 2 are juxtaposed in the width direction Y at predetermined intervals, and are arranged side by side in the width direction Y. A plurality of holding terminals 50 having substantially the same shape as the contact member 40 are attached to both ends of the plurality of contact members 40 in the width direction Y. In the present embodiment, the cable 2 that has been inserted into the casing 30 in 201223012 is held by engaging the holding terminal 50 with the holding hole 2c of the cable 2. Further, an insulating lever 60 is rotatably attached to the casing 30. Specifically, as shown in FIGS. 6 to 8, the lever 60 is rotated in a position between the open position (the state shown in FIG. 6) and the closed position (the state shown in FIG. 8). Mounted in the housing 30, the open position allows the cable 2 to be inserted into the housing 30. The closed position utilizes the contact member 40 to clamp the cable 2 that has been inserted into the housing 30. The casing 30 is formed of an insulating material such as synthetic resin, and has a pocket shape in which the cable 2 is inserted from the rear after the rear portion of the casing 30 (the left side of Fig. 6: the disengagement side of the cable insertion/removal direction). The cable accommodating portion (insertion port) 31 is formed in a substantially intermediate portion of the vertical direction Z. The cable accommodating portion 31 is formed by the top wall portion 32, the bottom wall portion 33, and the width direction formed at the rear of the casing 30. The two side wall portions 34, 34 at both ends of Y are divided and open at the rear. Further, as shown in Fig. 1, a front side wall portion (a pair of vertical wall portions) which is located outside the side wall portions 34 and 34 in the width direction Y is formed at both ends in the width direction Y of the front portion of the casing 30. 34a, 34a, and a bottom wall portion 34e is formed inside the front side walls 34a, 34a. Then, in front of the casing 30, a lever mounting portion 35 which is defined by the front side wall portions 34a, 34a and the bottom wall portion 34e and which is opened upward and forward is formed. A lever 60 is rotatably mounted to the lever mounting portion 35. Further, at both end portions in the width direction Y of the lever mounting portion 35, bearing portions 35a that are open to the upper side and the front side are formed, and the bearing portions 35a are opposed to each other in the width direction Y of the casing 30. In the present embodiment, the 'bearing portion 35a' as shown in Figs. -8-201223012 1 and Fig. 4 is an inner rear surface 34b and a bottom wall portion 34e that connect the connecting wall portion 34f of the side wall portion 34 and the front side wall portion 34a. The bottom surface 34c at both end portions in the width direction Y and the inner side surface 34d of the front side wall portion 34a are defined. Further, the lever 60 is a plate-like member that can be housed in the lever mounting portion 35 of the casing 30, and the lever 60 is also formed of an insulating material such as synthetic resin. Then, as shown in Fig. 1 and Fig. 2, the pivot shaft 61 is protruded from the proximal end side (one end side of the lever 60) on both end faces of the width direction Y of the lever 60. Further, the body of the lever 60 (the other end side of the lever 60) is an operation portion 62 for opening and closing (rotating operation) the lever 60. In the present embodiment, the pivot shaft 61 at both ends in the width direction Y of the lever 60 is placed at both ends in the width direction Y of the casing 30 from the front side of the casing 30 (opposite to the cable accommodating portion 31). The bearing portion 35a' and the holding fitting 70 are attached to the connecting wall portion (housing) 34f, and the lever 60 can be opened and closed (rotated) to be attached to the lever mounting portion 35 of the housing 30 (refer to Fig. 1 and 4 picture). As shown in Fig. 4, the holding metal fitting 70 is formed of a thin metal plate and has a main body portion 71 extending in the front-rear direction. Then, an insertion piece (insertion fixing portion) 71a is provided extending downward from the front portion of the main body portion 71, and a support piece 71b is extended downward from the rear portion of the main body portion 71, and is bent upward in front of the main body portion 71. The convex claw-shaped pivot shaft covering portion 71c extends forward. Then, the holding attachment 70 is attached to the connecting wall portions 34f and 34f so that the pivotal shaft covering portion 71c covers the upper side of the pivot shaft 61 and the front side (one end side of the insertion and removal direction of the cable 2). Specifically, in the connecting wall portions 34f and 34f, an insertion hole (recessed portion) 34g into which the insertion piece (insertion fixing portion) 71a is inserted is formed, and an insertion piece (insertion fixing portion) is inserted in the insertion hole (concave portion) 34g. The 7a is pressed (inserted) from above, whereby the holding fitting 70 is attached to the connecting wall portions 34f, 34f. Further, in the present embodiment, the wall portion 34h after the connection wall portion 34f is inserted into the concave portion 71d formed between the insertion piece (insertion fixing portion) 7la and the support piece 71b, and the insertion piece (insertion fixing portion) can be used. The 71a and the support piece 71b sandwich the rear wall portion 34h. Further, in the insertion piece (insertion fixing portion) 71a, projections 71e and 71e are provided at both ends in the front-rear direction. Then, the projections 71e and 71e are pressed into the inner surface of the insertion hole 34g (the front surface of the rear wall portion 34h and the rear surface of the front wall portion 34i), whereby the holding fitting 70 is locked. The crotch portions 34f and 34f are connected. As described above, in the present embodiment, the retaining piece 70 can be prevented from being detached by sandwiching the rear wall portion 34h by the insertion piece (insertion fixing portion) 71a and the supporting piece 71b. Further, the projections 71e and 71e are press-fitted so as to bite into the inner surface of the insertion hole 34g, whereby the holding fitting 70 can be prevented from being detached when the upward pivoting load is applied to the pivotal shaft covering portion 71c. . Further, in the present embodiment, as shown in Figs. 4 and 5, by attaching the holding metal fittings 70 to the connecting wall portions 34f and 34f and the outer circumference of the pivot shaft 61, the pivoting shaft covering portion 71c can be used. The inner front surface 34b and the bottom surface 34c are covered. -10- 201223012 Therefore, the pivot shaft 61 can restrict the upward and front movement by the pivot shaft covering portion 71c, and the rearward movement can be restricted by the inner front surface 34b, and can be supported by the bottom surface 3 4c to limit the movement towards the bottom. That is, when the pivotal shaft covering portion 71c has a load toward the front, when the pivot shaft 61 has moved to the upper or the front of the opening of the bearing portion 35a (one end side in the cable insertion direction), by holding the fitting 70 By restricting this movement, the lever 60 can be inhibited from being detached from the housing 30. Further, even if the lever 60 is detached from the contact 40, the movement of the pivot shaft 61 in the front-rear direction and the vertical direction can be restricted by holding the fitting 70 and the casing 30, so that the lever 60 can be prevented from being detached from the casing 30. . Thus, in the present embodiment, it is not necessary to inhibit the lever from being detached from the housing by engaging the lever with the retaining fitting and engaging the contact member, and the lever 60 can be inhibited from being detached from the housing 30 by the retaining fitting. . Further, in the present embodiment, when the pivot shaft covering portion 71c is bent at a radius of curvature larger than the diameter of the pivot shaft 61, the holding fitting 70 is attached to the joint wall portion 3 4f, 3 4f. At this time, a gap is formed between the pivot shaft covering portion 7 1 c and the pivot shaft 61. In other words, in the present embodiment, the holding metal fitting 70 can cover the upper side and the front side of the pivot shaft 61 (one end side of the insertion and removal direction of the cable 2) in a non-contact state. It is attached to the connection wall parts 34f and 34f. Therefore, the rotation of the pivot shaft 61 can be suppressed from being hindered, and the pivot shaft 61 can be smoothly rotated. As a result, it is not necessary to perform high-precision dimensional management such as cutting in order to ensure the rotation of the pivot shaft 61. Further, the pivot shaft 61 is supported by covering the pivot shaft 61 in a non-contact state.

止動件45a。然後，該止動件45a，係限制接觸件40插入 於容納部36時接觸件40之對殻體30的最大插入量。 又’該止動件45a，係兼作使連接器1安裝於電路基板6 時的表面安裝用之錫焊部，且比殼體30之底壁部33還更 朝向下方突出若干。 又’在端子臂部4 5之前端部，係設置有比縱壁部3 7 之底面37d(槓桿裝設部35之底壁部）還更朝上方突出的大 致山形之突起部45b，且在位於開啓位置的槓桿60朝前 後方向X前方移動（平行移動）時，槓桿60會抵接於突起 部45b。如此，突起部45b，就發揮作爲抑制槓桿60脫離 的止動件之功能。 又’如第6圖所示，可動側接觸件部42，係具備： -14- 201223012 可動側接觸部46，其係沿著頂壁部32而延伸於前後方向 X後側（可動側接觸件部42之一側）；以及彈簧部47，其 係沿著頂壁部3 2而延伸於前後方向X前側（可動側接觸件 部42之另一側）。更且，在可動側接觸件部42，係於上 側中央部設置有突起部42a。 然後’在可動側接觸部46之前端部，係形成有朝向 下方（插入後的纜線2)突出的可動側接點部46a，且該可 動側接點部46a接觸纜線2之導體。 在本實施形態中，在槓桿6 0位於開啓位置時，固定 側接點部44a與可動側接點部46a之間的距離，係成爲與 纜線2之厚度大致相同（參照第6圖）。又，在並未插入纜 線2的狀態下槓桿60位於閉合位置時，固定側接點部 44a與可動側接點部46a之間的距離，係變得比纜線2之 厚度還更小。因而，在槓桿60位於開啓位置時，可將纜 線2插入於殻體30，而在槓桿60位於閉合位置時，固定 側接點部44a與可動側接點部46a會壓接纜線2，且接觸 件40會夾持纜線2。 又，在彈簧部47之下面，係形成有後述的槓桿60之 凸輪部64所滑接的大致圓弧狀之凸輪面47a’且在該凸 輪面47a之前側形成有卡合突部（相互地卡合的凹凸 部）4 7d，該卡合突部47d係具有：連設於該凸輪面47a並 可供凸輪部64滑接的前端面47b;以及連設於該前端面 47b的水平面47c° 更且，在本實施形態中，頂壁部3 2，係覆蓋可動側 -15- 201223012 接觸部46之全部與彈簧部47之後側大致一半。又，在槓 桿60是位於開啓位置的狀態時，以成爲彈簧部47不接觸 頂壁部32的狀態之方式，將接觸件40卡止於殻體30。 亦即，在彈簧部47之上面與頂壁部32之下面之間形成有 間隙。在本實施形態中，以僅有設置於可動側接觸件部 42之上側中央部的突起部42a接觸頂壁部3 2的方式，將 接觸件40壓入於容納部36內，藉此彈簧部47不會接觸 頂壁部3 2 * 然後，在被彈.簧部47之頂壁部32覆蓋的部位（彈簧 部47之根側：後側）、與未被彈簧部47之頂壁部32覆蓋 的部位（彈簧部47之前端側：前側）之大致境界部分的上 部，設置有階差部47e。亦即，如第6圖所示，彈簧部 47，係形成根部之厚度比前端部還更厚。 又，連結彈簧部43，係具有彈簧性，且能夠彈性地 撓曲變形。在本實施形態中，連結彈簧部43，係在傾斜 於上方且後方的狀態下連結固定側接觸件部4 1及可動側 接觸件部42 »然後，在使彈簧部47朝彈簧部47之前端 與端子臂部45之前端相對地開啓的方向撓曲變形時，連 結彈簧部43就會彈性地撓曲變形，且可動側接觸件部42 之可動側接觸部46與固定側接觸件部4 1之固定側接觸部 44之間隔會變小。 又，如第9圖所示，在寬度方向Υ並列設置有複數 個的接觸件40之寬度方向Υ兩端，係分別安裝有與接觸 件40大致相同形狀的保持端子50，且藉由該保持端子50 -16- 201223012 來保持已插入於殼體30內的纜線2(參照第3圖）。 在本實施形態中，接觸件40之寬度方向γ兩端的保 持端子50,係與接觸件40同樣地，從前方容納於殼體30 之容納部36內並予以固定保持。 如第9圖及第10圖所示，該保持端子50，係具備： 棒狀的固定側保持部5 1，其係位於底壁部3 3近旁，且延 伸於前後方向X;以及棒狀的可動側保持部52，其係位 於頂壁部3 2近旁，且延伸於前後方向X，並與固定側保 持部51在上下方向（殼體30之厚度方向：纜線2之厚度 方向）Z對向。然後，固定側保持部51及可動側保持部 52，係藉由連結彈簧部53連結各自的前後方向（長度方 向）X之中間部彼此，且形成大致工字狀》 如第9圖及第10圖所示，固定側保持部51，係具 備：固定側保持臂54，其係沿著底壁部3 3而延伸於前後 方向X後側（固定側保持部5 1之一側）；以及支撐臂5 5 ’ 其係沿著底壁部33而延伸於前後方向X前側（固定側保持 部5 1之另一側）。 然後，在固定側保持臂54之前端部’係形成有朝向 上方（插入後的纜線2)突出的固定側卡合突部54a’而該 固定側卡合突部54a可從下側（背面側）插入於形成在纜線 2之寬度方向Y兩端的保持孔2c。該保持孔2c’係以貫 通於上下方向（厚度方向）Z的方式設置在：與已插入於殼 體30內之狀態下的纜線2之固定側卡合突部54a及後述 的可動側卡合突部56a對應之部位。 -17- 201223012 又，在支撐臂55之前端部，係形成有向下突出的止 動件55a。然後，該止動件55a，係限制保持端子50插入 於容納部36時的保持端子50之對殻體30的最大插入 量。 更且，在支撐臂55之前端部，係設置有比縱壁部37 之底面37d(槓桿裝設部35之底壁部）還更朝上方突出的大 致山形之突起部55b，且在位於開啓位置的槓桿60朝前 後方向X前方移動（平行移動）時，槓桿60會抵接於突起 部55b。如此，突起部55b，就發揮作爲抑制槓桿60脫離 的止動件之功能。 又’如第9圖及第10圖所示，可動側保持部52，係 具備：可動側保持臂56，其係沿著頂壁部32而延伸於前 後方向X後側（可動側保持部52之一側）；以及彈簧部 5 7 ’其係沿著頂壁部3 2而延伸於前後方向X前側（可動側 保持部52之另一側）。更且，在可動側保持部52，係於 上側中央部設置有突起部5 2 a。 又，在可動側保持臂5 6之前端部，係形成有朝向下 方（插入後的纜線2)突出的可動側卡合突部56a，且該可 動側卡合突部56a可從上側（表面側）插入於纜線2之保持 孔2c。另外’如第3圖所示，在對應於纜線2之保持端 子50的部位，並未設置導體2b。 又’在彈簧部57之下面，係形成有後述的槓桿60之 凸輪部64所滑接的大致圆弧狀之凸輪面57a，且在該凸 輪面57a之前側形成有卡合突部57d，該卡合突部57d係 -18- 201223012 具有：連設於該凸輪面5 7a並能夠供凸輪部64滑接的前 端面57b ;以及連設於該前端面57b的水平面57c。 另外，雖然省略了圖示，但是保持端子50也與接觸 件40同樣，頂壁部32，係覆蓋可動側保持臂56之全部 與彈簧部57之後側大致一半。又，在槓桿60是位於開啓 位置的狀態時，以成爲彈簧部57不接觸頂壁部32的狀態 之方式，將保持端子50卡止於殼體30。亦即’在彈簧部 57之上面與頂壁部32之下面之間形成有間隙。 然後，在被彈簧部57之頂壁部32覆蓋的部位（彈簧 部57之根側：後側）、與未被彈簧部57之頂壁部32覆蓋 的部位（彈簧部57之前端側：前側）之大致境界部分的上 部，設置有階差部57e。亦即，如第9圖所示，彈簧部 57,係形成根部之厚度比前端部還更厚。 又，連結彈簧部53，係具有彈簧性，且能夠彈性地 撓曲變形。然後，在使彈簧部57朝彈簧部57之前端與支 撐臂55之前端相對地開啓的方向撓曲變形時，連結彈簧 部53就會彈性地撓曲變形，且可動側保持部52之可動側 保持臂56與固定側保持部5 1之固定側保持臂54之間隔 會變小。 更且，在本實施形態中，如第9圖所示，至少在槓桿 60位於開啓位置時，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，設定得比接觸件 40中的固定側接觸部44之固定側接點部（前端）44a與可 動側接觸部4 6之可動側接點部（前端）4 6 a之間的距離D 2 -19- 201223012 還短。 因此，在保持端子50的連結彈簧部53及接觸件4〇 的連結彈簧部43分別撓曲時，在接觸件4〇之可動側接點 部46a接觸導體2b以前，保持端子50之可動側卡合突部 56a會卡合於保持孔2c。如此，在本實施形態中’係在使 接觸件40之可動側接點部46a接觸導體2b時’可更確實 地抑制纜線2偏位。 另外，在本實施形態中，係將接觸件4〇中的固定側 接觸部44之固定側接點部（前端）44a與可動側接觸部46 之可動側接點部（前端）46a之間的距離D2，設定成與纜線 2之厚度大致相同。因而，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（一對的卡合突部間 之距離）D 1，係變得比纜線2之厚度還更小。 又，如第1圖及第2圖所示，在槓桿60之一端部， 係以與分別設置於接觸件40及保持端子50的彈簧部 47、57對應的方式，形成有貫通孔63。更且，在鄰接於 槓桿60之貫通孔63的位置，係形成有：伴隨槓桿60之 轉動而轉動，且滑接於設置在彈簧部47、57之凸輪面 47a、57a的凸輪部6 4(參照第6圖至第8圖）。 在本實施形態中，凸輪部64，係具備：大致圓柱狀 的圓形部64a :以及連設於該圓形部64a之大致長方體狀 的方形部64b，且從前後方向X剖面觀察時形成大致鍵孔 狀。 又，凸輪部64，係具備：轉動承接面（旋轉承接 -20- 201223012 部）64c，其係與縱壁部37之底面37d(槓桿裝設部35之底 壁部）滑接，且在使槓桿60朝開閉方向轉動時成爲轉動支 點（旋轉支點）；以及抵接面（接觸件抵接面及保持端子抵 接面）64d，其係藉由槓桿60之轉動而與接觸件40及保持 端子50的彈簧部47、57之凸輪面47a、57a滑接。 更且，在凸輪部64，係具備：第1面64e，其係在槓 桿60呈全開狀態時，抵接於縱壁部37之底面37d(槓桿 裝設部35之底壁部）；以及第2面64f，其係在槓桿60呈 全關狀態時，抵接於縱壁部37之底面37d(槓桿裝設部35 之底壁部）。然後，第1面64e與第2面64f所成的角度 0 (參照第7圖）會變成銳角。另外，在本實施形態中，係 將第1面64e與第2面64f所成的角度0，設定成約77 度。又，在第1面64e與第2面64f之間，設置有上述的 凸輪部64之轉動承接面64c，且該轉動承接面64c，係形 成作爲曲率半徑較小的圓弧面。另外，將轉動承接面64c 之曲率半徑，設定成約〇.〇5mm。 然後，在本實施形態中’如第6圖所示，凸輪部 64，係在槓桿60位於開啓位置時，在橫方向（前後方向X) 變成細長，且上下方向Z之尺寸，變得比接觸件40的彈 簧部47與端子臂部45之間隔及彈簧部57與支撐臂55之 間隔還更小。亦即，在槓桿60位於開啓位置時，凸輪部 64與彈簧部47、57，係變成非接觸狀態。 然後，在使槓桿60朝閉合方向（第7圖之箭頭A方向） 轉動時，在以凸輪部64立起的方式轉動的途中，凸輪部 -21 - 201223012 部 會 點 抵 且 向 面 45 放 由 性 動 間 動 固 藉 線 可 且 會 壓 64之上下方向Z的尺寸，係變得比彈簧部47與端子臂 45之間隔及彈簧部57與支撐臂55之間隔還更大》 亦即，當使槓桿60朝閉合方向轉動時，凸輪部64 伴隨該槓桿60之轉動而將轉動承接面64c當作轉動支 來轉動。然後，在槓桿60之朝閉合方向轉動的途中， 接面64d會抵接於彈簧部47、57之凸輪面47a、57a， 與凸輪面47a、57a滑接。更且，當使槓桿60朝閉合方 轉動時’凸輪部64，係使抵接面64d —邊滑接於凸輪 47a、57a —邊轉動’且以彈簧部47之前端與端子臂部 之前端的間隔及彈簧部57與支撐臂55之間隔相對地開 的方式，使彈簧部47、57彈性地撓曲變形。然後，藉 連結彈簧部43、53伴隨彈簧部47、57之撓曲變形而彈 地撓曲變形，接觸件40就會以可動側接觸件部42的可 側接觸部46與固定側接觸件41的固定側接觸部44之 隔變小的方式彈性地撓曲變形，且保持端子50會以可 側保持部52的可動側保持臂56與固定側保持部5 1的 定側保持臂5 4之間隔變小的方式彈性地撓曲變形。 此’可動側接點部46a會朝固定側接點部44a方向移動 且在使可動側接點部46a與固定側接點部44a壓接於纜 2的狀態下，纜線2與接觸件40就會導通連接。又， 動側卡合突部56a會朝固定側卡合突部54a方向移動， 纜線2可藉由保持端子50而保持。如此，凸輪部64, 對接觸件40附加用以使該接觸件40壓接於纜線2的推 力’並且對保持端子50附加用以保持纜線2的推壓力。 -22- 201223012 另外，在本實施形態中，在使槓桿60從開啓位置朝 閉合方向轉動至閉合位置時，雖然在轉動至途中，凸輪部 64之高度會慢慢地變高，但是當超過預定的轉動量時， 凸輪部64之高度會慢慢地變低。又，凸輪部64可藉由彈 簧部47、57之彈性復原力而被推壓，藉此作用於槓桿60 的力矩之作用方向，在使槓桿60從開啓位置轉動至閉合 位置之途中，會從開啓方向朝閉合方向變化。 如此，在槓桿60轉動的途中，藉由使凸輪部64之旋 轉半徑縮小，或使作用於槓桿60的力矩之作用方向從開 啓方向朝閉合方向變化，就可在槓桿60之操作時提供定 位（c 1 i c k )感。 更且，在本實施形態中，如上所述，以在槓桿60之 開啓狀態下抵接於縱壁部37之底面37d(槓桿裝設部35 之底壁部）的第1面64e、與在槓桿60之閉合狀態下抵接 於縱壁部37之底面37d(槓桿裝設部35之底壁部）的第2 面64f所成的角度0變成銳角之方式形成凸輪部64之轉 動承接面（旋轉承接部）64c。因而，可將凸輪部64形成更 爲窄幅，且可使槓桿60容易旋轉。如此，藉由使槓桿60 容易旋轉，則在超過預定的轉動量而作用於槓桿60的力 矩之作用方向從開啓方向改變至閉合方向時，就可使槓桿 60比習知還更迅速地朝閉合方向轉動，藉此可使槓桿操 作之定位感增大。 又，藉由將轉動承接面（旋轉承接部）64c，形成結合 第1面64e與第2面64f的圓弧狀，就可更平順地進行槓 -23- 201223012 桿操作，並且可抑制轉動承接面（旋轉承接部）64c因槓桿 操作而被刮削。 另外，即使在從閉合方向朝開啓方向轉動時，亦可提 供同樣的定位感。 又，在本實施形態中，係在凸輪部 64之圓形部 64a，如第6圖及第11圖所示，形成有卡合於卡合突部 47d、5 7d的卡合凹部（相互地卡合的凹凸部）64g。該卡合 凹部64g，係以側面64h及圓弧面64i形成，該側面64h 係能夠與卡合突部47d、5 7d之前端面4 7b、5 7b抵接，該 圓弧面64i係能夠與卡合突部47d、57d之水平面47c、 57c抵接。然後，藉由前端面47b、57b與側面64h抵 接，並且水平面47c、57c與圓弧面64i抵接，而使卡合 突部47d、57d與卡合凹部64g卡合（參照第12圖）。 亦即，在本實施形態中，卡合突部47d、57d之前端 面4 7b、5 7b會限制槓桿60之朝前方的移動，且卡合突部 47d、57d之水平面47c、57c會限制槓桿60之朝上方的 移動。另外，亦可以使前端面47b、57b與側面64h及水 平面47c、57c與圓弧面64i相互地面接觸的方式構成。 如此就可更提高卡合突部47d、57d與卡合凹部64g之卡 合程度。 然而，在本實施形態中，雖然在彈簧部47、57與凸 輪部64，設置相互地卡合的凹凸部（卡合突部47d、57d 與卡合凹部64g)，但是該卡合突部47d、57d與卡合凹部 64g，在通常的槓桿60之開閉操作下並不會卡合（參照第 -24- 201223012 6圖）。 然後，在槓桿60之開閉操作時或非使用狀態（並未插 入纜線2的狀態）時等，會在開啓狀態之槓桿60施加朝前 方的荷重，且在槓桿60保持開啓狀態下朝前方且上方移 動（槓桿60朝相對於接觸件40脫離的方向相對移動）並越 過大致山形之突起部45b、55b的情況，會使卡合突部 47d、57d與卡合凹部64g卡合而抑制槓桿60從殼體30 脫離（參照第11圖及第12圖）。 如此，並非是在立即使其等卡合的狀態下抑制槓桿 60從殻體30脫離，而是除了可藉由在施加過度的負荷使 槓桿60朝脫離方向相對移動時使其等卡合，來提高槓桿 60之脫離阻止效果的可靠度以外，還可藉由並非是利用 單純的卡止而是利用凹凸部（卡合突部47d與卡合凹部 64g)使其等相互地卡合，來更抑制槓桿60從殼體30脫 離。 又，在開啓狀態之槓桿60施加朝前方的荷重之情 況，可藉由卡合突起47d之前端面47b與卡合凹部64g之 側面64h來限制槓桿60之朝前方的移動，並且也可藉由 水平面47c與圓弧面64i來限制槓桿之朝上方的移動，藉 以更加提高槓桿60之脫離阻止效果。 如此構成的槓桿60之朝殼體30的安裝，係可以如下 方式來進行。 首先，使彈簧部47、57之前端插通於槓桿60之貫通 孔63，並且從彈簧部47之前端與端子臂部45之前端之 -25- 201223012 間及彈簧部57之前端與支撐臂55之前端之間（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，將槓桿60之寬度方向Y兩端的樞支軸61載 置於殻體30之寬度方向Y兩端的軸承部35a’並且將保 持配件70安裝於連結壁部34f’藉此槓桿60就能夠開閉 (轉動）地安裝於殼體30之槓桿裝設部35。 另外，在本實施形態中，係在槓桿60位於開啓位置 時，藉由將凸輪部64在橫方向（前後方向X)形成細長， 則在使彈簧部47、57之前端插通於貫通孔63時’亦即， 使貫通孔63對向於彈簧部47、57之前端的狀態時，對向 於水平面47c、57c與突起部45b、55b之間的凸輪部64 之厚度會變小。因此，在從水平面47c、57c與突起部 45b、5 5b之間插入凸輪部64時，沒有必要用較大之力使 其壓入，就可使凸輪部64容易插入。 其次，根據第6圖至第1〇圖說明閉合槓桿60時的接 觸件40及保持端子50之動作。 首先，如第6圖所示，在槓桿60位於開啓位置時， 可動側接觸件部42之彈簧部47，雖然會接近殼體30之 頂壁部32，但是並未與頂壁部32接觸。亦即，可動側接 觸件部42之彈簧部47與頂壁部32，成爲具有間隙而離 開的狀態。此時，槓桿60之凸輪部64與彈簧部47之凸 輪面47a，會成爲非卡合的狀態。又，雖然省略了圖示， 但是可動側保持部52之彈簧部57也是成爲同樣的狀態。 -26 - 201223012 亦即，可動側保持部52之彈簧部57與頂壁部32，成爲 具有間隙而離開的狀態，並且槓桿6 0之凸輪部6 4與彈簧 部57之凸輪面57a，成爲非卡合的狀態。 其次，將纜線2插入於殼體30內。此時，由於接觸 件40中的固定側接觸部44之固定側接點部（前端）44a與 可動側接觸部46之可動側接點部（前端）46a之間的距離 D2，與纜線2之厚度大致相同，所以可抑制在纜線2與 接觸件40之間發生摩擦力，且可將纜線2平順地插入於 殼體30內。又，由於保持端子50的固定側卡合突部54a 與可動側卡合突部56a之距離（一對的卡合突部間之距 離）D 1，係比纜線2之厚度還更小，所以在將纜線2插入 於殼體30內時，固定側卡合突部54a與可動側卡合突部 5 6a就可從纜線2之表背面插入於保持孔2c。藉此，纜線 2可藉由保持端子50而暫時保持。因而，即使是在槓桿 60位於開啓位置的狀態，亦可抑制纜線2脫離。另外， 在本實施形態中，藉由將保持端子50逐個設置於接觸件 40之寬度方向Y兩端，即可極力地抑制在纜線2與保持 端子50之間發生的摩擦力之增加，且可極力地抑制纜線 2之朝殼體30內的平順插入因保持端子50而受到阻礙。 然後，在已將纜線2插入於殼體30內的狀態下，當 將槓桿60朝箭頭A所示的順時鐘方向轉動時，接觸件抵 接面64d，就會如第7圖所示，抵接於彈簧部47之凸輪 面47a，且與凸輪面47a滑接。更且，當使槓桿60朝閉 合方向轉動時，凸輪部64，就會使接觸件抵接面64d與 -27- 201223012 凸輪面47a —邊滑接一邊轉動，且以接觸件40的彈簧部 47之前端與端子臂部45之前端之間隔相對地開放的方 式，使彈簧部47彈性地撓曲變形。另外，在槓桿60朝閉 合方向轉動之途中，彈簧部47之大致中間部會接觸頂壁 部32»又，即使在保持端子50中也是進行同樣的動作， 且在槓桿60朝閉合方向轉動之途中，經撓曲變形後的彈 簧部57，係使其大致中間部接觸頂壁部32。 然後，伴隨彈簧部47之撓曲變形，連結彈簧部43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，接觸件40，就會以可動側接觸件部42的可動側 接觸部46與固定側接觸件部41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）變小的 方式彈性地撓曲變形。亦即，可動側接點部46a會朝固定 側接點部44a方向移動。結果，纜線2，係在可動側接點 部46a與固定側接點部44a經壓接後的狀態下，導通連接 於接觸件40。 此時，如第10圖所示，在保持端子50方面，係在使 彈簧部57及連結彈簧部53撓曲時，會以可動側保持部 52的可動側芦持臂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D 1)變小的方式彈性地撓曲變形。結果，成爲可動 側卡合突部56a及固定側卡合突部54a可從纜線2之表背 面側更插入於保持孔2c的狀態。亦即，可更增大可動側 卡合突部56a及固定側卡合突部54a與保持孔2e之卡合 -28- 201223012 程度，且保持端子5 〇會牢固地保持纜線2 °如此’在 實施形態中，由於藉由將可動側卡合突部56a及固定側 合突部54a從纜線2之表背兩面側插入於保持孔2c’ 持端子5 0就會保持纜線2，所以即使在纜線2之厚度 均等或外力作用於纜線2的情況，纜線2也不容易脫落 亦即，在本實施形態中，可抑制纜線2從連接器1脫離 .如此，在本實施形態中，係將保持端子5 0之形狀 成與接觸件40之形狀大致同樣的形狀，且藉由槓桿60 轉動，可動側卡合突部56a及固定側卡合突部54a之間 距離（一對的卡合突部間之距離）D1就會變化。亦即， 由槓桿60之轉動，可進行可動側卡合突部5 6a及固定 卡合突部54a朝保持孔2c之卡合。如此，沒有必要與 觸件40之導通連接個別地進行藉由保持端子5〇保持纜 2用的操作，可提高連接器1之操作性。 在此，在本實施形態中，係在使槓桿60朝閉合方 轉動，且使彈簧部47、57之全體朝頂壁部32之方向撓 時，在槓桿60之朝閉合方向轉動的途中，彈簧部47、 之大致中間部會接觸頂壁部32。 更且’在使槓桿60更進一步朝閉合方向轉動時， 彈簧部47、57之大致中間部接觸頂壁部32的狀態下， 桿60會轉動至閉合位置。亦即，在本實施形態中，係 使槓桿60朝閉合方向轉動，且使可動側接點部46a與 定側接點部44a壓接於纜線2的狀態下，彈簧部47之 致中間部會接觸頂壁部32(參照第8圖）。又，雖然省略 本 卡 保 不 形 之 的 藉 側 接 線 向 曲 57 在 槓 在 固 大 了 29 201223012 圖示，但是保持端子50也是與接觸件40同樣，使槓桿 60朝閉合方向轉動，且在保持端子50保持纜線2的狀態 下，彈簧部57之大致中間部會接觸頂壁部32。 更且，在本實施形態中，如第7圖及第8圖所示，設 置於彈簧部47、57之大致中間部的階差部47e、57e近旁 之根側會接觸頂壁部3 2(在第7圖及第8圖中，雖然是顯 示接觸件40，但是保持端子50也是同樣）。亦即，在彈 簧部47、57接觸到頂壁部32之後，前端側之厚度比階差 部47e、57e還更薄的部分會朝上方撓曲變形。 如以上說明，在本實施形態中，在使槓桿60朝閉合 方向轉動，且使彈簧部47之全體朝頂壁部32之方向撓曲 時，在槓桿60之朝閉合方向轉動的途中，彈簧部47之大 致中間部會接觸到頂壁部3 2 » 然而，如第13圖所示，在已使槓桿60朝閉合方向轉 動，且使彈簧部47之全體朝頂壁部32之方向撓曲時，當 彈簧部47並未接觸頂壁部32時，因彈簧部47及可動側 接觸部46之撓曲而造成的應力，就會集中於連結彈簧部 43，而有使連結彈簧部43彈性疲乏之虞。另外，即使在 保持端子50方面也是同樣，有使連結彈簧部53彈性疲乏 之虞。 然而，如本實施形態，若在槓桿60之朝閉合方向轉 動的途中，使彈簧部47之大致中間部接觸頂壁部32，則 在可動側接觸件部42撓曲時，就可使因接觸件40之撓曲 而發生的應力，也集中於與彈簧部47之頂壁部（殻體30 -30- 43 201223012 內壁）3 2之接觸部位。結果，可分散加在連結彈簧部 的應力，且可減少朝連結可動側接觸件部42與固定側 觸件部41的連結彈簧部43之局部的應力集中，而可抑 連結彈簧部43彈性疲乏。 又，在本實施形態中，即使在已使槓桿60朝閉合 向轉動，且使可動側接點部46a與固定側接點部44a壓 於纜線2的狀態（即將纜線2安裝於連接器1的狀態）下 彈簧部47之大致中間部也會接觸頂壁部32。 因而，由於即使在連接器1使用時（使槓桿60轉動 閉合位置並使壓接纜線2的狀態時），也可分散加在連 彈簧部43的應力，所以可提高連接器1的製品壽命。 又，在本實施形態中，係設爲：設置在彈簧部47 大致中間部的階差部47e近旁之根側接觸頂壁部3 2， 在彈簧部47接觸到頂壁部32之後，前端側之厚度比階 部47e還更薄的部分會朝上方撓曲變形。 如此’藉由以階差部47e、57e爲基點而使彈簧 47、57撓曲，就可更有效率地使應力集中於彈簧部47 57。因而，可更抑制連結彈簧部43、53彈性疲乏。 以上，雖然已就本發明的較佳實施形態加以說明， 是本發明並未被限定於上述實施形態，而是可進行各種 變化。 例如’彈簧部或連結彈簧部之形狀，並不被限定於 述實施形態所例示者，亦可設爲各種的形狀。 又’殻體或槓桿、凸輪部、其他細部的規格（形狀 接 制 方 接 至 結 之 且 差 部 但 的 上 -31 - 201223012

slidably accommodated in the bearing portion 35a. Further, in the present embodiment, as described above, the lever 60 is rotated from the open position shown in Fig. 6 to the eighth The closed position shown in the figure is mounted to the housing 30. Then, when the lever 60 is in the open position, the lever 60 is erected from the lever mounting portion 35 of the housing 30 in an upright posture, and the front side of the lever mounting portion 35 is opened substantially above the housing 30 (refer to Figure 6). At this time, the cable 2 can be inserted into the cable housing portion 31 of the housing 30. Further, on one end side of the operation portion 62 of the lever 60 (the rear side in a state where the lever 60 is in the open position), a step is formed by the inclined portion 62a and the flat portion 62b, and the lever 60 is rotated in the opening direction. At this time, 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 lever 60 in the opening direction can be restricted by connecting the upper end portion of the inner rear surface 34b of the wall portion 34f. On the other hand, when the lever 60 is in the closed position, the lever 60 is in a substantially horizontal posture and is accommodated in the lever mounting portion 35 of the housing 30, and is clamped by the contact member 40 and inserted into the cable housing portion 3 1 Cable 2 inside (refer to Figure 8). The contact member 40 is provided in plural in the width direction Y of the casing 30, and the contact member 40 is formed by punching a sheet metal. Further, the contact 40 is fixedly held by being inserted into the casing 30 from the front (see Figs. 6 to 8). In the present embodiment, the housing 30 is provided with a plurality of housing portions 36 for accommodating a plurality of contacts 40 so as to extend through the front-rear direction X, and each of the housing portions 36 extends from front to back -12-201223012 The vertical wall portion 37 of the direction X is spaced apart. In other words, in the present embodiment, each of the accommodating portions 36 is formed so as to penetrate the front-rear direction X by the top wall portion 32, the bottom wall portion 33, and the vertical wall portion 37, and the accommodating portion 36 is 1 in each of the accommodating portions 36. The contacts 40 are inserted from the front. Then, as shown in Fig. 6, in the rear portion of the vertical wall portion 3, a slit 37a opening to the rear is formed, and the insertion of the thin-plate-shaped cable 2 toward the cable housing portion 31 is not carried out. The wall portion 37 obstructs. Further, by the inner deep wall surface 37b formed in the deep portion (the front side in the front-rear direction) inside the slit 37a, the movement of the cable 2 toward the front (insertion direction) can be restricted. Further, the front portion of the vertical wall portion 37 has a shape of a l-shaped slit, and is formed in a substantially U shape when viewed from the front-rear direction X section. Then, it is divided into the lever mounting portion 35 by the front side surface 37c and the bottom surface 37d of the vertical wall portion 37. As described above, in the present embodiment, a portion of the above-described bottom wall portion 34e is formed in the front portion of the vertical wall portion 37. Further, in the present embodiment, the bottom surface 3 7d of the vertical wall portion 37 is formed to be slightly above the bottom surfaces 34c and 34c of the front side wall portions 34a and 34a. In other words, in the present embodiment, the bearing portion 35a at both ends in the width direction γ is formed to be slightly deeper so that the lever mounting portion 35° is not provided as the contact member 40 in the second drawing, and is provided in a rod shape. The fixed side contact portion 41 is located in the vicinity of the bottom wall portion 33 and extends in the front-rear direction X; and a rod-shaped movable side contact portion 42 which is located near the top wall portion 32 and extends in the front-rear direction X. The fixed side contact portion 41 is oriented in the vertical direction (the thickness direction of the casing 30: the thickness direction of the cable 2) by two pairs of -13 - 201223012. Then, the fixed side contact portion 4 1 and the movable side contact portion 42 are connected to each other in the intermediate portion of the front-rear direction (longitudinal direction) X by the connecting spring portion 43, and are formed in a substantially I-shape. As shown in Fig. 6, the fixed-side contact portion 41 includes a fixed-side contact portion 44 that extends along the bottom wall portion 33 in the front-rear direction X rear side (one of the fixed-side contact portions 41) And a terminal arm portion 45 extending along the bottom wall portion 33 in the front-rear direction X front side (the other side of the fixed-side contact portion 4 1). Then, at the end portion of the fixed-side contact portion 44, a fixed-side contact portion 44a that protrudes upward (the inserted cable 2) is formed, and the fixed-side contact portion 44a contacts the conductor of the cable 2. Further, at the end portion of the terminal arm portion 45, a stopper 45a that protrudes downward is formed. Then, the stopper 45a limits the maximum insertion amount of the contact member 40 to the casing 30 when the contact member 40 is inserted into the accommodating portion 36. Further, the stopper 45a serves as a soldering portion for surface mounting when the connector 1 is attached to the circuit board 6, and protrudes downward from the bottom wall portion 33 of the casing 30. Further, the front end portion of the terminal arm portion 45 is provided with a substantially mountain-shaped projection 45b that protrudes upward from the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35), and When the lever 60 in the open position moves forward (parallel movement) in the front-rear direction X, the lever 60 abuts against the projection 45b. Thus, the projection 45b functions as a stopper for suppressing the disengagement of the lever 60. Further, as shown in Fig. 6, the movable side contact portion 42 is provided with: -14 - 201223012 movable side contact portion 46 which extends along the top wall portion 32 in the front and rear direction X rear side (movable side contact member) One side of the portion 42); and a spring portion 47 extending along the top wall portion 32 in the front side in the front-rear direction X (the other side of the movable-side contact portion 42). Further, in the movable side contact portion 42, a projection portion 42a is provided at the upper center portion. Then, at the end portion of the movable side contact portion 46, a movable side contact portion 46a that protrudes downward (the inserted cable 2) is formed, and the movable side contact portion 46a contacts the conductor of the cable 2. In the present embodiment, when the lever 60 is at the open position, the distance between the fixed side contact portion 44a and the movable side contact portion 46a is substantially the same as the thickness of the cable 2 (see Fig. 6). Further, when the lever 60 is in the closed position in a state where the cable 2 is not inserted, the distance between the fixed side contact portion 44a and the movable side contact portion 46a becomes smaller than the thickness of the cable 2. Thus, when the lever 60 is in the open position, the cable 2 can be inserted into the housing 30, and when the lever 60 is in the closed position, the fixed side contact portion 44a and the movable side contact portion 46a can crimp the cable 2, And the contact 40 will hold the cable 2. Further, on the lower surface of the spring portion 47, a substantially arc-shaped cam surface 47a' to which the cam portion 64 of the lever 60 to be described later is slid is formed, and an engaging projection is formed on the front side of the cam surface 47a (inter-joining The engaging projection 47d has a front end surface 47b connected to the cam surface 47a and slidably coupled to the cam portion 64, and a horizontal surface 47c connected to the front end surface 47b. Further, in the present embodiment, the top wall portion 32 covers substantially all of the movable side -15 - 201223012 contact portion 46 and the rear side of the spring portion 47. Further, when the lever 60 is in the open position, the contact 40 is locked to the casing 30 so that the spring portion 47 does not contact the top wall portion 32. That is, a gap is formed between the upper surface of the spring portion 47 and the lower surface of the top wall portion 32. In the present embodiment, the contact portion 40 is press-fitted into the accommodating portion 36 so that only the protruding portion 42a provided at the center portion on the upper side of the movable-side contact portion 42 contacts the top wall portion 32, whereby the spring portion 47 will not touch the top wall 3 2 * Then, in the bomb. The boundary between the portion where the top wall portion 32 of the spring portion 47 is covered (the root side of the spring portion 47: the rear side) and the portion not covered by the top wall portion 32 of the spring portion 47 (the front end side of the spring portion 47: the front side) The upper portion of the portion is provided with a step portion 47e. That is, as shown in Fig. 6, the spring portion 47 is formed to have a thicker root portion than the front end portion. Further, the connecting spring portion 43 is spring-like and elastically deformable. In the present embodiment, the connecting spring portion 43 is coupled to the fixed side contact portion 41 and the movable side contact portion 42 in a state of being inclined upward and rearward, and then the spring portion 47 is directed toward the front end of the spring portion 47. When the direction in which the front end of the terminal arm portion 45 is opened is flexed and deformed, the connecting spring portion 43 is elastically flexibly deformed, and the movable side contact portion 46 and the fixed side contact portion 4 of the movable side contact portion 42 are separated. The interval between the fixed side contact portions 44 becomes small. Further, as shown in Fig. 9, the plurality of contact members 40 are provided in parallel in the width direction, and the holding terminals 50 having substantially the same shape as the contacts 40 are attached to each other by the holding. The terminal 50 -16-201223012 holds the cable 2 inserted into the casing 30 (refer to Fig. 3). In the present embodiment, the holding terminals 50 at both ends in the width direction γ of the contact member 40 are housed in the accommodating portion 36 of the casing 30 from the front side and fixedly held in the same manner as the contact member 40. As shown in FIGS. 9 and 10, the holding terminal 50 includes a rod-shaped fixed-side holding portion 5 1 which is located near the bottom wall portion 33 and extends in the front-rear direction X; and a rod-like shape. The movable-side holding portion 52 is located in the vicinity of the top wall portion 32 and extends in the front-rear direction X, and is in the vertical direction (the thickness direction of the casing 30: the thickness direction of the cable 2) Z with the fixed-side holding portion 51. to. Then, the fixed-side holding portion 51 and the movable-side holding portion 52 are connected to each other in the intermediate portion of the front-rear direction (longitudinal direction) X by the connecting spring portion 53, and are formed in a substantially I-shaped shape, as shown in FIG. 9 and FIG. As shown in the figure, the fixed-side holding portion 51 includes a fixed-side holding arm 54 that extends along the bottom wall portion 33 in the front-rear direction X rear side (one side of the fixed-side holding portion 51); and support The arm 5 5 ' extends along the bottom wall portion 33 in the front side in the front-rear direction X (the other side of the fixed-side holding portion 51). Then, before the fixed-side holding arm 54, the end portion ' is formed with a fixed-side engaging projection 54a' that protrudes upward (the inserted cable 2) and the fixed-side engaging projection 54a can be from the lower side (back) The side) is inserted into the holding hole 2c formed at both ends in the width direction Y of the cable 2. The holding hole 2c' is provided so as to penetrate the vertical direction (thickness direction) Z so as to be engaged with the fixed side engagement projection 54a of the cable 2 in a state of being inserted into the casing 30, and a movable side card to be described later. The portion where the protruding portion 56a corresponds. -17- 201223012 Further, at the front end portion of the support arm 55, a stopper 55a that protrudes downward is formed. Then, the stopper 55a limits the maximum insertion amount of the holding terminal 50 to the casing 30 when the holding terminal 50 is inserted into the accommodating portion 36. Further, at the end portion of the support arm 55, a substantially mountain-shaped projection 55b that protrudes upward from the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35) is provided, and is located at the opening. When the lever 60 of the position moves forward (parallel movement) in the front-rear direction X, the lever 60 abuts against the protrusion 55b. Thus, the projection 55b functions as a stopper for suppressing the disengagement of the lever 60. Further, as shown in FIGS. 9 and 10, the movable-side holding portion 52 includes a movable-side holding arm 56 that extends along the top wall portion 32 in the front-rear direction X (the movable-side holding portion 52). One side); and a spring portion 5 7 ' extends along the top wall portion 32 in the front side in the front-rear direction X (the other side of the movable-side holding portion 52). Further, the movable side holding portion 52 is provided with a projection portion 5 2 a at the upper center portion. Further, at the end portion of the movable-side holding arm 56, a movable-side engagement projection 56a that protrudes downward (the inserted cable 2) is formed, and the movable-side engagement projection 56a can be from the upper side (surface) The side) is inserted into the holding hole 2c of the cable 2. Further, as shown in Fig. 3, the conductor 2b is not provided at a portion corresponding to the holding terminal 50 of the cable 2. Further, on the lower surface of the spring portion 57, a substantially arc-shaped cam surface 57a on which the cam portion 64 of the lever 60 to be described later is slid is formed, and an engagement projection 57d is formed on the front side of the cam surface 57a. The engaging projection 57d is a -18-201223012 having a front end surface 57b connected to the cam surface 57a and capable of sliding the cam portion 64, and a horizontal surface 57c connected to the front end surface 57b. Further, although not shown, the holding terminal 50 is also similar to the contact member 40, and the top wall portion 32 covers substantially all of the movable side holding arm 56 and the rear side of the spring portion 57. Further, when the lever 60 is in the open position, the holding terminal 50 is locked to the casing 30 so that the spring portion 57 does not contact the top wall portion 32. That is, a gap is formed between the upper surface of the spring portion 57 and the lower surface of the top wall portion 32. Then, the portion covered by the top wall portion 32 of the spring portion 57 (the root side of the spring portion 57: the rear side) and the portion not covered by the top wall portion 32 of the spring portion 57 (the front end side of the spring portion 57: the front side) The upper part of the approximate boundary portion is provided with a step portion 57e. That is, as shown in Fig. 9, the spring portion 57 is formed to have a thicker root portion than the front end portion. Further, the connecting spring portion 53 has spring property and is elastically deformable. Then, when the spring portion 57 is flexibly deformed in a direction in which the front end of the spring portion 57 is opened opposite to the front end of the support arm 55, the joint spring portion 53 is elastically flexibly deformed, and the movable side of the movable side holding portion 52 is movable. The interval between the holding arm 56 and the fixed side holding arm 54 of the fixed side holding portion 51 is reduced. Further, in the present embodiment, as shown in Fig. 9, at least when the lever 60 is at the open position, the distance D1 between the fixed-side engagement projection 54a of the holding terminal 50 and the movable-side engagement projection 56a is set. The distance D 2 -19 between the fixed side contact portion (front end) 44a of the fixed side contact portion 44 in the contact member 40 and the movable side contact portion (front end) 46 a of the movable side contact portion 46 is obtained. 201223012 is still short. Therefore, when the connecting spring portion 53 of the holding terminal 50 and the connecting spring portion 43 of the contact member 4b are respectively deflected, the movable side card of the terminal 50 is held before the movable side contact portion 46a of the contact member 4b contacts the conductor 2b. The engaging portion 56a is engaged with the holding hole 2c. As described above, in the present embodiment, when the movable-side contact portion 46a of the contact 40 is brought into contact with the conductor 2b, the cable 2 can be more reliably suppressed from being displaced. Further, in the present embodiment, the fixed side contact portion (front end) 44a of the fixed side contact portion 44 of the contact member 4A and the movable side contact portion (front end) 46a of the movable side contact portion 46 are provided. The distance D2 is set to be substantially the same as the thickness of the cable 2. Therefore, the distance between the fixed-side engagement projections 54a of the holding terminal 50 and the movable-side engagement projections 56a (the distance between the pair of engagement projections) D1 becomes smaller than the thickness of the cable 2 . Further, as shown in Figs. 1 and 2, a through hole 63 is formed in one end portion of the lever 60 so as to correspond to the spring portions 47 and 57 provided on the contact member 40 and the holding terminal 50, respectively. Further, at a position adjacent to the through hole 63 of the lever 60, a cam portion 64 that is rotated by the rotation of the lever 60 and is slidably attached to the cam faces 47a, 57a of the spring portions 47, 57 is formed ( Refer to Figures 6 to 8). In the present embodiment, the cam portion 64 includes a substantially cylindrical circular portion 64a and a substantially rectangular parallelepiped portion 64b connected to the circular portion 64a, and is formed substantially when viewed from the front-rear direction X. Keyhole shape. Further, the cam portion 64 includes a rotation receiving surface (rotation receiving member -20-201223012 portion) 64c which is slidably coupled to the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35), and is When the lever 60 rotates in the opening and closing direction, it becomes a pivot point (rotation fulcrum); and the abutting surface (contact abutting surface and holding terminal abutting surface) 64d, which is rotated by the lever 60 with the contact member 40 and the holding terminal. The cam faces 47a, 57a of the spring portions 47, 57 of 50 are slidably coupled. Further, the cam portion 64 includes a first surface 64e that abuts against the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35) when the lever 60 is fully opened; The two faces 64f are in contact with the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35) when the lever 60 is in the fully closed state. Then, the angle 0 (see Fig. 7) formed by the first surface 64e and the second surface 64f becomes an acute angle. Further, in the present embodiment, the angle 0 formed by the first surface 64e and the second surface 64f is set to about 77 degrees. Further, between the first surface 64e and the second surface 64f, the above-described rotation receiving surface 64c of the cam portion 64 is provided, and the rotation receiving surface 64c is formed as an arcuate surface having a small radius of curvature. In addition, the radius of curvature of the rotating receiving surface 64c is set to about 〇. 〇 5mm. Then, in the present embodiment, as shown in Fig. 6, the cam portion 64 is elongated in the lateral direction (forward and backward direction X) when the lever 60 is at the open position, and the size of the vertical direction Z becomes contact. The distance between the spring portion 47 of the member 40 and the terminal arm portion 45 and the distance between the spring portion 57 and the support arm 55 are also smaller. That is, when the lever 60 is in the open position, the cam portion 64 and the spring portions 47, 57 are brought into a non-contact state. Then, when the lever 60 is rotated in the closing direction (the direction of the arrow A in FIG. 7), the cam portion - 21302302 is offset and placed on the surface 45 while the cam portion 64 is being erected. The dynamic moving solid-state borrowing line can press the size of the upper and lower directions Z of the 64, and becomes larger than the interval between the spring portion 47 and the terminal arm 45 and the interval between the spring portion 57 and the support arm 55. When the lever 60 is rotated in the closing direction, the cam portion 64 rotates with the rotation receiving surface 64c as a pivotal branch as the lever 60 rotates. Then, in the middle of the rotation of the lever 60 in the closing direction, the joint surface 64d abuts against the cam faces 47a, 57a of the spring portions 47, 57, and is slidably engaged with the cam faces 47a, 57a. Further, when the lever 60 is rotated toward the closing side, the 'cam portion 64 is rotated while the abutting surface 64d is slidably engaged with the cams 47a, 57a' and the front end of the spring portion 47 is spaced from the front end of the terminal arm portion. The spring portions 47 and 57 are elastically deformed and deformed so that the spring portions 57 are spaced apart from the support arms 55. Then, the connecting spring portions 43, 53 are flexibly deformed by the flexural deformation of the spring portions 47, 57, and the contact member 40 is the side contact portion 46 and the fixed side contact portion 41 of the movable side contact portion 42. The fixed side contact portion 44 is elastically flexibly deformed in such a manner that the gap is small, and the holding terminal 50 is held by the fixed side holding arm 56 of the movable side holding arm 56 and the fixed side holding portion 51 of the movable side holding portion 52. The manner in which the interval becomes smaller is elastically flexed and deformed. The movable side contact portion 46a moves in the direction of the fixed side contact portion 44a, and the cable 2 and the contact member 40 are in a state where the movable side contact portion 46a and the fixed side contact portion 44a are crimped to the cable 2. Will be connected. Further, the movable side engagement projection 56a moves in the direction of the fixed side engagement projection 54a, and the cable 2 can be held by the holding terminal 50. Thus, the cam portion 64 adds a pushing force for pressing the contact member 40 to the cable 2 to the contact member 40 and attaches a pressing force for holding the cable 2 to the holding terminal 50. -22-201223012 In addition, in the present embodiment, when the lever 60 is rotated from the open position to the closed position to the closed position, the height of the cam portion 64 gradually becomes higher during the rotation, but when the predetermined time is exceeded At the amount of rotation, the height of the cam portion 64 gradually becomes lower. Further, the cam portion 64 can be urged by the elastic restoring force of the spring portions 47, 57, whereby the direction of action of the moment acting on the lever 60 causes the lever 60 to be rotated from the open position to the closed position. The opening direction changes toward the closing direction. Thus, during the rotation of the lever 60, positioning can be provided during operation of the lever 60 by reducing the radius of rotation of the cam portion 64 or changing the direction of action of the moment acting on the lever 60 from the opening direction to the closing direction ( c 1 ick ). Further, in the present embodiment, as described above, the first surface 64e that abuts against the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35) in the open state of the lever 60 is When the angle 0 of the second surface 64f of the bottom surface 37d of the vertical wall portion 37 (the bottom wall portion of the lever mounting portion 35) in the closed state of the lever 60 is changed to an acute angle, the rotation receiving surface of the cam portion 64 is formed ( Rotating the receiving portion) 64c. Thus, the cam portion 64 can be formed to be more narrow and the lever 60 can be easily rotated. Thus, by making the lever 60 easy to rotate, 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 closed more quickly than is conventionally known. The direction is rotated, whereby the positioning feeling of the lever operation is increased. Further, by rotating the receiving surface (rotation receiving portion) 64c to form an arc shape in which the first surface 64e and the second surface 64f are joined, the rod 23-201223012 rod operation can be performed more smoothly, and the rotation receiving can be suppressed. The surface (rotation receiving portion) 64c is scraped by the lever operation. In addition, the same positioning feeling can be provided even when rotating from the closing direction to the opening direction. Further, in the present embodiment, as shown in FIGS. 6 and 11 , the circular portion 64a of the cam portion 64 is formed with engagement recesses that are engaged with the engagement projections 47d and 57d (mutually). Engaged concave and convex portion) 64g. The engaging recessed portion 64g is formed by a side surface 64h and an arcuate surface 64i, and the side surface 64h can abut against the front end faces 47b and 57b of the engaging projections 47d and 57d, and the arcuate surface 64i can be coupled with the card. The horizontal surfaces 47c and 57c of the joint projections 47d and 57d abut. Then, 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 are engaged with the engagement concave portion 64g (see Fig. 12). . That is, in the present embodiment, the front end faces 47b, 57b of the engaging projections 47d, 57d restrict the forward movement of the lever 60, and the horizontal faces 47c, 57c of the engaging projections 47d, 57d restrict the lever 60. Move to the top. 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 placed in contact with each other on the ground. Thus, the degree of engagement between the engaging projections 47d, 57d and the engaging recess 64g can be further improved. However, in the present embodiment, the spring portions 47 and 57 and the cam portion 64 are provided with the uneven 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 engaging recessed portion 64g are not engaged by the normal opening and closing operation of the lever 60 (refer to Fig. 24-201223012, Fig. 6). Then, when the lever 60 is opened or closed or in a non-use state (a state in which the cable 2 is not inserted), the lever 60 in the open state applies a load toward the front, and the lever 60 is kept open while the lever 60 is kept open. When the upper movement (the lever 60 relatively moves in the direction in which the lever 40 is disengaged) and the substantially mountain-shaped projections 45b and 55b are passed, the engagement projections 47d and 57d are engaged with the engagement recesses 64g to restrain the lever 60. It is detached from the casing 30 (refer to Figs. 11 and 12). In this manner, the lever 60 is prevented from being detached from the casing 30 in a state in which it is immediately engaged, but the hook 60 can be engaged by being moved in the disengaging direction when an excessive load is applied. In addition to the reliability of the detachment preventing effect of the lever 60, it is possible to use the uneven portion (the engaging projection portion 47d and the engaging recess portion 64g) to be engaged with each other, not by simple locking. The restraining lever 60 is disengaged from the housing 30. Further, in the case where the lever 60 in the open state applies the load toward the front, the forward movement of the lever 60 can be restricted by the front end surface 47b of the engaging projection 47d and the side surface 64h of the engaging recess 64g, and can also be controlled by the horizontal plane. The 47c and the circular arc surface 64i restrict the upward movement of the lever, thereby further improving the detachment prevention effect of the lever 60. The attachment of the lever 60 thus constructed to the housing 30 can be performed in the following manner. First, the front ends of the spring portions 47, 57 are inserted through the through holes 63 of the lever 60, and from the front end of the spring portion 47 to the front end of the terminal arm portion 45 between -25 and 201223012 and the front end of the spring portion 57 and the support arm 55. The cam portion 64 is inserted between the front ends (i.e., 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 lever 60 is placed on the bearing portion 35a' at both ends in the width direction Y of the casing 30, and the holding fitting 70 is attached to the joint wall portion 34f', whereby the lever 60 can be opened and closed. The lever mounting portion 35 of the housing 30 is attached (rotated). Further, in the present embodiment, when the lever 60 is at the open position, the cam portion 64 is elongated in the lateral direction (the front-rear direction X), and the front ends of the spring portions 47, 57 are inserted into the through-holes 63. In other words, when the through hole 63 is opposed to the front end of the spring portions 47 and 57, the thickness of the cam portion 64 between the horizontal surfaces 47c and 57c and the projections 45b and 55b is reduced. Therefore, when the cam portion 64 is inserted between the horizontal surfaces 47c, 57c and the projections 45b, 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 contact member 40 and the holding terminal 50 when the lever 60 is closed will be described based on Fig. 6 to Fig. 1 . First, as shown in Fig. 6, when the lever 60 is in the open position, the spring portion 47 of the movable-side contact portion 42 comes close to 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 and the top wall portion 32 of the movable side contact portion 42 are separated from each other 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 in a non-engaged state. Further, although not shown, the spring portion 57 of the movable-side holding portion 52 is also in the same state. -26 - 201223012, that is, the spring portion 57 and the top wall portion 32 of the movable-side holding portion 52 are separated from each other by a gap, and the cam portion 64 of the lever 60 and the cam surface 57a of the spring portion 57 become non- The state of the snap. 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 contact member 40 and the movable side contact portion (front end) 46a of the movable side contact portion 46, and the cable 2 Since the thickness is substantially the same, it is possible to suppress the occurrence of friction between the cable 2 and the contact 40, and the cable 2 can be smoothly inserted into the casing 30. Moreover, the distance D1 between the fixed-side engagement projections 54a 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, Therefore, when the cable 2 is inserted into the casing 30, the fixed-side engagement projection 54a and the movable-side engagement projection 56a can be inserted into the holding hole 2c from the front and back surfaces of the cable 2. Thereby, the cable 2 can be 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 the holding terminals 50 one by one in the width direction Y of the contact 40, the increase in the frictional force generated between the cable 2 and the holding terminal 50 can be suppressed as much as possible, and It is possible to suppress as much as possible that the smooth insertion of the cable 2 into the casing 30 is hindered by the holding terminal 50. Then, in a state where the cable 2 has been inserted into the casing 30, when the lever 60 is rotated in the clockwise direction indicated by the arrow A, the contact abutting surface 64d is as shown in Fig. 7, It abuts against the cam surface 47a of the spring portion 47 and is slidably coupled to the cam surface 47a. Further, when the lever 60 is rotated in the closing direction, the cam portion 64 rotates the contact abutting surface 64d and the -27-201223012 cam surface 47a while sliding, and the spring portion 47 of the contact member 40. The spring portion 47 is elastically flexibly deformed such that the front end is open to the front end of the terminal arm portion 45. Further, in the middle of the rotation of the lever 60 in the closing direction, the substantially intermediate portion of the spring portion 47 contacts the top wall portion 32», and the same operation is performed even in the holding terminal 50, and the lever 60 is rotated in the closing direction. The spring portion 57 that has been flexed and deformed has a substantially intermediate portion that contacts the top wall portion 32. Then, with the deflection of the spring portion 47, the connecting spring portion 43 is elastically deformed. By bending the spring portion 47 and the connecting spring portion 43, the contact member 40 is spaced apart from the fixed side contact portion 44 of the fixed side contact portion 41 by the movable side contact portion 46 of the movable side contact portion 42. The distance between the movable side contact portion 46a and the fixed side contact portion 44a is elastically deformed. That is, 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 contact 40 in a state where the movable side contact portion 46a and the fixed side contact portion 44a are pressure-bonded. At this time, as shown in FIG. 10, when the spring portion 57 and the connecting spring portion 53 are flexed while holding the terminal 50, the movable side holding arm 56 and the fixed side holding portion of the movable side holding portion 52 are provided. The distance between the fixed side holding arms 54 of 51 (the distance D1 between the movable side engaging projections 56a and the fixed side engaging projections 54a) is elastically flexibly deformed. As a result, the movable side engagement projection 56a and the fixed side engagement projection 54a can be inserted into the holding hole 2c from the front side of the cable 2. That is, the degree of engagement of the movable side engaging projection 56a and the fixed side engaging projection 54a with the holding hole 2e can be further increased, and the terminal 5 保持 can securely hold the cable 2 ° so In the embodiment, the movable side engagement projection 56a and the fixed side engagement projection 54a are inserted into the holding hole 2c' from the front and back sides of the cable 2 to hold the terminal 50, so that the cable 2 is held. Even in the case where the thickness of the cable 2 is equal or an external force acts on the cable 2, the cable 2 does not easily fall off, that is, in the present embodiment, the cable 2 can be prevented 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 contact 40, and the movable side engaging projection 56a and the fixed side engaging projection 54a are rotated by the lever 60. The distance between them (the distance between the pair of engaging projections) D1 changes. That is, by the rotation of the lever 60, the engagement between the movable side engagement projection portion 56a and the fixed engagement projection portion 54a toward the holding hole 2c can be performed. Thus, it is not necessary to individually perform the operation for holding the cable 2 by holding the terminal 5〇 with the conduction connection of the contact 40, and the operability of the connector 1 can be improved. Here, in the present embodiment, when the lever 60 is rotated toward the closed side and the entire spring portions 47 and 57 are bent in the direction of the top wall portion 32, the spring is rotated in the closing direction of the lever 60. The substantially intermediate portion of the portion 47 contacts the top wall portion 32. Further, in a state where the substantially intermediate portion of the spring portions 47, 57 contacts the top wall portion 32 when the lever 60 is further rotated in the closing direction, the lever 60 is rotated to the closed position. In other words, in the present embodiment, the lever 60 is rotated in the closing direction, and the movable side contact portion 46a and the fixed side contact portion 44a are pressed against the cable 2, and the intermediate portion of the spring portion 47 is caused. The top wall portion 32 is brought into contact (see Fig. 8). Moreover, although the boring of the indirect side of the card is shown in Fig. 57, the holding terminal 50 is also rotated as in the contact 40, and the lever 60 is rotated in the closing direction, and is maintained. In a state where the terminal 50 holds the cable 2, the substantially intermediate portion of the spring portion 57 contacts the top wall portion 32. Further, in the present embodiment, as shown in Figs. 7 and 8, the root side of the step portions 47e and 57e provided near the intermediate portions of the spring portions 47 and 57 contact the top wall portion 3 2 ( In Figs. 7 and 8, although the contact member 40 is shown, the holding terminal 50 is the same). That is, after the spring portions 47, 57 are in contact with the top wall portion 32, the portion of the front end side which is thinner than the step portions 47e, 57e is flexibly deformed upward. As described above, in the present embodiment, when the lever 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 portion is rotated in the closing direction of the lever 60. The substantially intermediate portion of the portion 47 is in contact with the top wall portion 3 2 » However, as shown in Fig. 13, when the lever 60 has been rotated in the closing direction and the entire spring portion 47 is deflected toward the top wall portion 32, When the spring portion 47 does not contact the top wall portion 32, the stress caused by the deflection of the spring portion 47 and the movable side contact portion 46 concentrates on the connection spring portion 43, and the connection spring portion 43 is elastically fatigued. Hey. Further, even in the case of holding the terminal 50, the connection spring portion 53 is elastically fatigued. However, according to the present embodiment, when the substantially intermediate portion of the spring portion 47 is brought into contact with the top wall portion 32 in the middle of the rotation of the lever 60 in the closing direction, the contact can be made when the movable-side contact portion 42 is flexed. The stress generated by the deflection of the member 40 is also concentrated on the contact portion with the top wall portion of the spring portion 47 (the inner wall of the casing 30 -30-43 201223012) 32. As a result, the stress applied to the connection spring portion can be dispersed, and the stress concentration in the portion of the connection spring portion 43 connecting the movable side contact portion 42 and the fixed side contact portion 41 can be reduced, and the elastic connection of the connection spring portion 43 can be suppressed. . Further, in the present embodiment, even 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 (that is, the cable 2 is attached to the connector). In the state of 1), the substantially intermediate portion of the lower spring portion 47 also contacts the top wall portion 32. Therefore, since the stress applied to the joint spring portion 43 can be dispersed even when the connector 1 is used (when the lever 60 is rotated to the closed position and the state of the cable 2 is crimped), the product life of the connector 1 can be improved. . Further, in the present embodiment, the root side is provided adjacent to the top wall portion 3 2 in the vicinity of the step portion 47e at the substantially intermediate portion of the spring portion 47, and after the spring portion 47 contacts the top wall portion 32, the front end side is The portion whose thickness is thinner than the step portion 47e is flexibly deformed upward. Thus, by bending the springs 47 and 57 with the step portions 47e and 57e as the base points, the stress can be more efficiently concentrated on the spring portion 47 57. Therefore, it is possible to further suppress the elastic fatigue of the joint spring portions 43, 53. Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made. For example, the shape of the spring portion or the connecting spring portion is not limited to those exemplified in the embodiments, and various shapes may be employed. In addition, the specifications of the case, the lever, the cam portion, and other details (the shape is connected to the junction and the difference is -31 - 201223012 size, layout, etc.) can be changed as appropriate.
