專利文獻1的連接器，當轉動操作操作槓桿時，在其轉動過程各凸輪部相對於端子的支承部滑動。通常操作槓桿是以合成樹脂等的電絕緣材所作成，強度較金屬板構件也就是端子更低，在反覆進行上述操作槓桿的轉動操作之後，該操作槓桿的凸輪部會與端子的支承部的板厚面摩擦而磨耗。該凸輪部磨耗的話，因應該磨耗量，會讓該凸輪部或該凸輪部的轉動中心從正規的位置朝下方偏移。結果，操作槓桿的轉動過程的凸輪部的軌跡會與正規軌跡不同，所以無法得到原本應得的卡嗒感等的操作感，例如，可能讓操作槓桿不易操作或產生操作槓桿的位置誤認。 In the connector of Patent Document 1, when the operation lever is rotated, each cam portion slides relative to the support portion of the terminal during the rotation. Generally, the operating lever is made of electrical insulating materials such as synthetic resin and has a lower strength than the metal plate member, that is, the terminal. After the rotation operation of the operating lever is repeatedly performed, the cam portion of the operating lever and the supporting portion of the terminal The thick surface of the board is rubbed and abraded. If the cam portion is worn, the cam portion or the rotation center of the cam portion may be shifted downward from a regular position according to the amount of wear. As a result, the trajectory of the cam portion during the rotation of the operating lever may be different from the normal trajectory, so that an operation feeling such as a click sense that is due to it cannot be obtained. For example, the operating lever may be difficult to operate or the position of the operating lever may be misidentified.

本發明鑒於這種情形，要提供一種平型導體電連接器，即使因可動構件的轉動讓該可動構件的凸輪部磨耗的情況，對於可動構件的操作，也能將操作感維持接近正規的操作感。 In view of this situation, the present invention is to provide a flat-type conductive electrical connector, which can maintain the operation feeling close to regular operation even when the cam portion of the movable member is worn due to the rotation of the movable member. sense.

The third cam portion 67 has its lower front edge inclined upward as it goes forward, and its lower rear edge inclined upward as it goes rearward, and the lower edge of the transition portion (junction portion) between the lower front edge and the lower rear edge. Create a protruding edge protruding downward. The third cam portion 67 supports the support arm portion 46 from below with the protruding edge at the open position.

在第3凸輪部67的上部朝後方突出的緣部作成圓弧狀，在可動構件60的轉動過程與上述受壓臂部44滑動接觸(參考第7圖(C)、第8圖(C))。第3凸輪部67的前緣，作成朝上下方向延伸的直線狀，當可動構件60來到關閉位置時，成為朝前後方向延伸的狀態，藉由支承臂部46從下方支承(參考第9圖(C))。 An edge portion protruding rearward from the upper portion of the third cam portion 67 is formed in an arc shape, and slides into contact with the pressure receiving arm portion 44 during the rotation of the movable member 60 (refer to FIG. 7 (C), FIG. 8 (C) ). The leading edge of the third cam portion 67 is formed in a straight line extending in the up-down direction. When the movable member 60 reaches the closed position, it is extended in the front-back direction and is supported from below by the support arm portion 46 (refer to FIG. 9). (C)).

可動構件60，當在開啟位置時，在端子排列方向的端子不在範圍，如第6圖(D)所示，其可動構件60的下面在與殼體10的底壁15的限制部15C之間具有上下方向的間隙。 When the movable member 60 is in the open position, the terminals in the terminal arrangement direction are out of range. As shown in FIG. 6 (D), the lower surface of the movable member 60 is between the lower portion 15C of the housing 10 and the restricting portion 15C of the housing 10 There is a gap in the vertical direction.

這樣組成的本實施方式的連接器1，以下面方式使用且功能如下。 The connector 1 of this embodiment configured as described above is used in the following manner and functions as follows.

首先，將連接器1配置在電路基板(並未圖示)上的預定位置，將第1端子20的連接部26A、第2端子30的連接部36A、及配件40的焊接固定部47A分別與電路基板的對應部焊接連接並且固定。 First, the connector 1 is arranged at a predetermined position on a circuit board (not shown), and the connection portion 26A of the first terminal 20, the connection portion 36A of the second terminal 30, and the soldering portion 47A of the accessory 40 are respectively connected to Corresponding parts of the circuit board are soldered and fixed.

針對安裝於電路基板的連接器1，將可動構件60調到如第6圖所示的豎立的開啟位置，讓殼體10的收容部16成為朝向後方(在圖中為左方)開口的狀態，成為可讓平型導體F***的狀態。 Regarding the connector 1 mounted on the circuit board, the movable member 60 is adjusted to the upright open position as shown in FIG. 6, and the housing portion 16 of the housing 10 is opened toward the rear (left in the figure). Is in a state where the flat conductor F can be inserted.

接著，在可動構件60在如第6圖所示的開啟位置的狀態，將平型導體F的連接部分(並未圖示)朝向前方***到上述收容部16內。第1端子20，其按壓臂部25的按壓部25A與接觸臂部27的接觸部27A之間成為較平型導體F的上述連接部分的厚度稍寬的間隔，而容易將該平型導體F的連接部分***。可是，關於上述配件40，由於該配件40的卡止臂部45的卡止部45A與直狀臂部47之間成為較上述平型導體F的連接部分的厚度更窄的間隔，所以平型導體F其前端，藉由使上述卡止部45A彈性變形而抬起，一邊使上述間隔擴大一邊前進至預定位置之後，上述卡止部45A從上方進入平型導體F的缺口狀的被卡止部F2，藉此暫時保持著平型導體F。 Next, in a state where the movable member 60 is in the open position as shown in FIG. 6, the connection portion (not shown) of the flat conductor F is inserted forward into the accommodation portion 16. The first terminal 20 has a slightly wider gap between the thickness of the connection portion of the flat conductor F and the pressing portion 25A of the pressing arm portion 25 and the contact portion 27A of the contact arm portion 27, so that the flat conductor F is easy. The connection part is inserted. However, the fitting 40 has a narrower interval between the locking portion 45A of the locking arm portion 45 and the straight arm portion 47 of the fitting 40 than the thickness of the connection portion of the flat conductor F. The front end of the conductor F is lifted by elastically deforming the locking portion 45A, and the gap is widened while advancing to a predetermined position. Then, the locking portion 45A enters the notch-shaped locked portion of the flat conductor F from above. The portion F2 temporarily holds the flat conductor F.

平型導體F的連接部分即使如上述***，由於上述可動構件60位於開啟位置，所以在作為第1端子20的下臂部22的後半部的接觸臂部27的下緣所形成的接觸部27A，其位置與殼體10的底壁15分離而形成間隙。 Even if the connection portion of the flat conductor F is inserted as described above, since the movable member 60 is located in the open position, the contact portion 27A formed at the lower edge of the contact arm portion 27 which is the rear half of the lower arm portion 22 of the first terminal 20 Its position is separated from the bottom wall 15 of the casing 10 to form a gap.

接著使可動構件60朝向關閉位置轉動。當可動構件60開始從開啟位置的轉動時，首先第2凸輪部66與第2端子30的支承臂部36滑動接觸。藉由該滑動接觸 讓可動構件60的轉動中心朝上方移動，結果，第1凸輪部65將第1端子20的受壓臂部24朝上方按壓移位，且第3凸輪部67將配件40的受壓臂部44朝上方按壓移位。第1凸輪部65及第3凸輪部67，在可動構件60開始轉動之後，分別與第1端子20的支承臂部26及配件40的支承臂部46之間具有間隙，而不會與該支承臂部26、46滑動接觸。也就是從上述受壓臂部24、44對於凸輪部65、67朝向下方作用的全部反作用力，只會被上述第2凸輪部66與上述支承臂部36的滑動接觸部位所承受。於是第2凸輪部66與上述支承臂部36，會在承受較大接觸壓力的狀態滑動接觸，容易產生第2凸輪部66的磨耗。 Next, the movable member 60 is rotated toward the closed position. When the movable member 60 starts to rotate from the open position, first, the second cam portion 66 is in sliding contact with the support arm portion 36 of the second terminal 30. With this sliding contact When the center of rotation of the movable member 60 is moved upward, as a result, the first cam portion 65 presses and shifts the pressure receiving arm portion 24 of the first terminal 20 upward, and the third cam portion 67 moves the pressure receiving arm portion 44 of the accessory 40. Press upward to shift. After the first cam portion 65 and the third cam portion 67 start to rotate, there is a gap between the first cam portion 65 and the third cam portion 67 and the support arm portion 26 of the first terminal 20 and the support arm portion 46 of the attachment 40, respectively, and they do not interfere with the support. The arms 26, 46 are in sliding contact. That is, all the reaction forces acting downward from the pressure receiving arm portions 24 and 44 on the cam portions 65 and 67 will be received only by the sliding contact portion between the second cam portion 66 and the support arm portion 36. Therefore, the second cam portion 66 and the support arm portion 36 are brought into sliding contact with each other in a state of receiving a large contact pressure, and the second cam portion 66 is liable to wear.

當可動構件60從開啟位置進行轉動時，如第7圖所示，第1凸輪部65抵接於支承臂部26且第3凸輪部67抵接於支承臂部46，在該時間點以後的轉動過程，所有凸輪部65、66、67對於支承臂部26、36、46滑動接觸。於是，從受壓臂部24、44對於凸輪部65、67朝向下方作用的反作用力，被所有凸輪部65、66、67與支承臂部26、36、46的滑動接觸部位所承受，藉此減輕第2凸輪部66與上述支承臂部36的接觸壓力。在該轉動過程，凸輪部65、67將受壓臂部24、44進一步朝上方按壓。 When the movable member 60 is rotated from the open position, as shown in FIG. 7, the first cam portion 65 abuts on the support arm portion 26 and the third cam portion 67 abuts on the support arm portion 46. During the rotation, all the cam portions 65, 66, 67 are in sliding contact with the support arm portions 26, 36, 46. Then, the reaction forces acting downward from the pressure-receiving arm portions 24 and 44 on the cam portions 65 and 67 are received by the sliding contact portions of all the cam portions 65, 66 and 67 and the support arm portions 26, 36 and 46, thereby The contact pressure between the second cam portion 66 and the support arm portion 36 is reduced. During this rotation, the cam portions 65 and 67 press the pressure-receiving arm portions 24 and 44 further upward.

可動構件60進一步轉動，如第8圖所示，凸輪部65、67將受壓臂部24、44進一步朝上方按壓時，該受壓臂部24、44朝上方的移位量成為最大，結果，第1 端子20的按壓臂部25及配件40的卡止臂部45具有最大的移位量而朝下方移位。 The movable member 60 further rotates, and as shown in FIG. 8, when the cam portions 65 and 67 press the pressure-receiving arm portions 24 and 44 further upward, the amount of upward displacement of the pressure-receiving arm portions 24 and 44 becomes the maximum. First The pressing arm portion 25 of the terminal 20 and the locking arm portion 45 of the accessory 40 are displaced downward with the maximum amount of displacement.

當可動構件60進一步轉動來到關閉位置時，如第9圖所示，凸輪部65、66、67各下緣(當在開啟位置時的前緣)被支承臂部26、36、46所支承，將可動構件60維持在上述關閉位置。此時，藉由按壓凸輪部65、67所造成的受壓臂部24、44朝上方的移位量，相較於第8圖所示的狀態更減少。藉由該構造，在朝向關閉位置的可動構件60的轉動操作中，可獲得凸輪部65、66、67越過第8圖所示的轉動角度位置時的卡嗒感。 When the movable member 60 is further rotated to the closed position, as shown in FIG. 9, the lower edges (leading edges when in the open position) of the cam portions 65, 66, and 67 are supported by the support arm portions 26, 36, and 46. , The movable member 60 is maintained in the above-mentioned closed position. At this time, the amount of upward displacement of the pressure receiving arm portions 24 and 44 caused by pressing the cam portions 65 and 67 is smaller than that in the state shown in FIG. 8. With this structure, in the turning operation of the movable member 60 toward the closed position, it is possible to obtain a click feeling when the cam portions 65, 66, and 67 pass the rotation angle position shown in FIG. 8.

如上述當可動構件60來到關閉位置時，第1端子20的按壓臂部25具有充分的移位量而朝下方移位，藉由按壓部25A從上方按壓平型導體F(並未圖示)。結果，讓接觸臂部27、37的接觸部27A、37A與平型導體F的下面的連接電路部具有充分的接觸壓力而接觸且電導通。配件40的卡止臂部45具有充分的移位量而朝下方移位，藉由讓卡止部45A深入平型導體F的被卡止部F2，與具有充分卡止量的該被卡止部F2的前緣維持卡止狀態，確實地防止平型導體F脫落。 As described above, when the movable member 60 reaches the closed position, the pressing arm portion 25 of the first terminal 20 has a sufficient amount of displacement and is displaced downward, and the flat conductor F (not shown) is pressed from above by the pressing portion 25A. ). As a result, the contact portions 27A and 37A of the contact arm portions 27 and 37 and the lower connection circuit portion of the flat conductor F are brought into contact with each other and electrically conductive. The locking arm portion 45 of the accessory 40 is displaced downward with a sufficient amount of displacement, and the locking portion 45A is caused to penetrate into the locked portion F2 of the flat conductor F and the locked portion having a sufficient locking amount. The leading edge of the portion F2 is kept locked, and the flat conductor F is reliably prevented from falling off.

如第6圖(D)、第7圖(D)、第8圖(D)、第9圖(D)所示，可動構件60，在正規位置，在從開啟位置至關閉位置之間的任一轉動角度位置，都在可動構件60與殼體10的限制部15C之間形成間隙，該可動構件60不會與限制部15C滑動接觸。 As shown in FIG. 6 (D), FIG. 7 (D), FIG. 8 (D), and FIG. 9 (D), the movable member 60 is in the normal position and any position from the open position to the closed position. At a rotation angle position, a gap is formed between the movable member 60 and the restricting portion 15C of the housing 10, and the movable member 60 does not slide into contact with the restricting portion 15C.

在本實施方式的連接器1，每次在開啟位置與關閉位置之間進行可動構件60的轉動操作，反覆進行讓電絕緣材製的可動構件60的凸輪部65、66、67與金屬板製的端子20、30的支承臂部26、36或配件40的支承臂部46的滑動接觸，結果會讓凸輪部65、66、67磨耗。尤其是在從第6圖所示的開啟位置起至第7圖所示的轉動位置之間，如上述，由於第2凸輪部66與第2端子30的支承臂部36的接觸壓力變大，所以容易產生第2凸輪部66的磨耗。 In the connector 1 of this embodiment, each time the rotating operation of the movable member 60 is performed between the open position and the closed position, the cam portions 65, 66, and 67 of the movable member 60 made of an electrically insulating material and the metal plate are repeatedly performed. The sliding contact of the supporting arm portions 26 and 36 of the terminals 20 and 30 or the supporting arm portion 46 of the accessory 40 will cause the cam portions 65, 66 and 67 to wear. Especially from the opening position shown in FIG. 6 to the rotation position shown in FIG. 7, as described above, since the contact pressure between the second cam portion 66 and the support arm portion 36 of the second terminal 30 increases, Therefore, abrasion of the second cam portion 66 easily occurs.

凸輪部65、66、67磨耗的話，因應該磨耗量，會讓該凸輪部65、66、67從正規的位置朝下方偏移。如果可動構件60從正規位置偏移過多的話，該可動構件60的轉動過程的凸輪部65、66、67的軌跡會與正規軌跡不同，所以無法得到原本應得的卡嗒感等的操作感，例如，可能讓可動構件60不易操作或產生可動構件60的位置誤認。並且在關閉位置，端子20的按壓臂部25的彈性移位量變小，無法獲得平型導體F與端子20、30的充分的接觸壓力，讓電導通狀態變得不穩定。而且配件40的卡止臂部45的彈性移位量變小，無法獲得配件40的卡止部45A相對於平型導體F的被卡止部F2的充分的卡止量，無法充分防止平型導體F脫落。 If the cam portions 65, 66, and 67 are worn, the cam portions 65, 66, and 67 will be shifted downward from the regular positions according to the amount of wear. If the movable member 60 is excessively shifted from the regular position, the locus of the cam portions 65, 66, and 67 during the rotation of the movable member 60 will be different from the regular locus, so that the operation feeling such as the click feeling that should be obtained cannot be obtained. For example, the movable member 60 may be made difficult to operate or the position of the movable member 60 may be misidentified. Further, in the closed position, the amount of elastic displacement of the pressing arm portion 25 of the terminal 20 becomes small, and sufficient contact pressure between the flat conductor F and the terminals 20 and 30 cannot be obtained, making the electrical conduction state unstable. In addition, the amount of elastic displacement of the locking arm portion 45 of the accessory 40 becomes small, and a sufficient locking amount of the locking portion 45A of the accessory 40 with respect to the locked portion F2 of the flat conductor F cannot be obtained, and the flat conductor cannot be sufficiently prevented. F comes off.

在本實施方式，在凸輪部65、66、67磨耗而可動構件60從正規位置朝下方偏移的情況，該可動構件60即使在從開啟位置起至關閉位置的任一位置，在端子 不在範圍上述殼體10的底壁15的限制部15C從下方抵接於該可動構件60。於是，於是限制了可動構件60的預定量以上的下降，並且防止凸輪部65、66、67進一步的磨耗。如上述，上述限制部15C形成為將可動構件60的轉動過程的凸輪部65、66、67的軌跡偏移保持在允許範圍的程度的高度尺寸，結果，讓可動構件60從正規位置的下降量不會過大，能良好地維持：可動構件60的操作感、平型導體F與端子20、30的接觸壓力或電導通狀態、平型導體F與配件40的卡止狀態等。 In the present embodiment, when the cam portions 65, 66, and 67 are worn out and the movable member 60 is shifted downward from the regular position, the movable member 60 is in the terminal even at any position from the open position to the closed position. The restricting portion 15C of the bottom wall 15 of the case 10 that is out of range abuts the movable member 60 from below. Then, the lowering of the movable member 60 by a predetermined amount or more is restricted, and further wear of the cam portions 65, 66, 67 is prevented. As described above, the restricting portion 15C is formed to a height dimension that keeps the track offset of the cam portions 65, 66, and 67 of the turning process of the movable member 60 within an allowable range, and as a result, the movable member 60 is lowered from the regular position by an amount It is not too large and can be maintained well: the operational feeling of the movable member 60, the contact pressure or electrical conduction state of the flat conductor F and the terminals 20, 30, the locked state of the flat conductor F and the attachment 40, and the like.

在本實施方式，只有可動構件60從正規位置下降預定量時，殼體10的限制部15C會抵接於可動構件60。假設作成即使在可動構件60在正規位置的情況，限制部15C也抵接於可動構件60的話，則會因連接器1的各構件的尺寸誤差或組裝誤差而產生各種缺失。例如，限制部15C抵接於位於正規位置的可動構件60，而會在該可動構件60的凸輪部65、66、67與端子20、30及配件40的支承臂部26、36、46之間形成沒有預期的間隙，則可能產生讓該凸輪部65、66、67不被支承臂部26、36、46支承的缺失。 In this embodiment, only when the movable member 60 is lowered by a predetermined amount from the regular position, the restricting portion 15C of the housing 10 comes into contact with the movable member 60. It is assumed that even when the movable member 60 is in the regular position, the restricting portion 15C abuts on the movable member 60, and various defects may occur due to the size error or assembly error of each member of the connector 1. For example, the restricting portion 15C abuts on the movable member 60 located at the regular position, and is between the cam portions 65, 66, and 67 of the movable member 60 and the support arms 26, 36, and 46 of the terminals 20, 30, and the accessory 40 If an unexpected gap is formed, the cam portion 65, 66, 67 may not be supported by the support arm portions 26, 36, 46.

相對的在本實施方式，當可動構件60在正規位置時，該可動構件60與限制部15C之間形成有間隙而未抵接，只有當該可動構件60從正規位置下降預定量時，也就是只有當凸輪部65、66、67磨耗預定量時，限制部15C才會抵接於可動構件60。於是藉由本實施方 式，當連接器1製造時，即使產生尺寸誤差或組裝誤差，只要該誤差在允許範圍內，就不會產生上述的缺失。結果，藉由本實施方式可容易製造連接器1。 In contrast, in the present embodiment, when the movable member 60 is in the regular position, a gap is formed between the movable member 60 and the restricting portion 15C without contacting, and only when the movable member 60 is lowered from the regular position by a predetermined amount, that is, Only when the cam portions 65, 66, and 67 wear out a predetermined amount, the restricting portion 15C comes into contact with the movable member 60. So with this embodiment When the connector 1 is manufactured, even if a dimensional error or an assembly error occurs, as long as the error is within the allowable range, the above-mentioned defect will not occur. As a result, the connector 1 can be easily manufactured by this embodiment.

<第2實施方式> <Second Embodiment>

在第1實施方式，在端子排列方向的端子不在範圍在殼體10的底壁15形成限制部15C來限制可動構件60的預定量以上的下降，而在本實施方式，與第1實施方式不同之處在於：並未如第1實施方式將限制部設置在底壁，藉由使可動構件的端子不在範圍的下端位於較其他範圍的下端更下方，來限制可動構件的預定量以上的下降。在本實施方式，在與第1實施方式對應的部分，用在第1實施方式的圖號加上100的圖號，以與第1實施方式的差異點為中心來說明。 In the first embodiment, the terminals in the terminal arrangement direction are not in the range. A restricting portion 15C is formed in the bottom wall 15 of the housing 10 to restrict the fall of the movable member 60 by a predetermined amount or more. This embodiment is different from the first embodiment. The point is that the restricting portion is not provided on the bottom wall as in the first embodiment, and the lower end of the movable member is not lower than the lower end of the other range to restrict the movable member from falling more than a predetermined amount. In this embodiment, the part corresponding to the first embodiment will be described with reference to the figure number of the first embodiment plus the figure number of 100, focusing on the differences from the first embodiment.

如第11圖(A)、(C)所示，當可動構件160位於開啟位置時，第1凸輪部165及第3凸輪部167，與第1實施方式的第1凸輪部65同樣地，相對於端子排列方向呈直角的剖面全體作成朝前後方向延伸的細長形狀，其位置分別在第1端子120的支承臂部126及配件140的支承臂部146的上緣之間具有上下方向的間隙。凸輪部 165、167，其後半部形成為被導引部165A、167A，其前半部形成為被支承部165B、167B，這也與第1實施方式的第1凸輪部65相同。 As shown in FIGS. 11 (A) and (C), when the movable member 160 is in the open position, the first cam portion 165 and the third cam portion 167 are opposite to each other in the same manner as the first cam portion 65 of the first embodiment. The cross-sections that are orthogonal to the terminal arrangement direction are all formed in an elongated shape extending in the front-rear direction, and the positions thereof have gaps in the vertical direction between the upper edges of the support arm portion 126 of the first terminal 120 and the support arm portion 146 of the accessory 140. Cam section 165 and 167. The rear half portions are formed as guided portions 165A and 167A, and the front half portions are formed as supported portions 165B and 167B. This is also the same as the first cam portion 65 of the first embodiment.

第2凸輪部166，如第11圖(B)所示，當可動構件160位於開啟位置時，作成朝前後方向延伸的大致長方形狀，該第2凸輪部166的後部的下緣藉由第2端子130的支承臂部136的上緣從下方支承。該第2凸輪部166，其上部的後端緣突出，在可動構件160的轉動過程及關閉位置，以該突出的部分從下方按壓第2端子130的受壓臂部134的受壓部134A(參考第12圖(B)及第13圖(B))。 As shown in FIG. 11 (B), when the movable member 160 is in the open position, the second cam portion 166 is formed in a substantially rectangular shape extending in the front-rear direction. The lower edge of the rear portion of the second cam portion 166 passes through the second portion. The upper edge of the support arm portion 136 of the terminal 130 is supported from below. The second cam portion 166 has a rear end edge protruding from the upper portion thereof, and presses the pressure receiving portion 134A of the pressure receiving arm portion 134 of the second terminal 130 with the protruding portion from below during the rotation process and the closed position of the movable member 160 ( Refer to Figure 12 (B) and Figure 13 (B)).

可動構件160，當在開啟位置時，在端子排列方向的端子不在範圍的一部分，具體來說，在端子排列範圍外的配件140的位置以外的範圍(以下稱為「預定端子不在範圍」)，上述可動構件160的下緣其位置涵蓋前後方向全區域較上述預定端子不在範圍以外的範圍的下緣更朝下方突出。上述預定端子不在範圍的可動構件160的前緣，其位置涵蓋上下方向全區域較上述預定端子不在範圍以外的範圍的前緣更朝前方突出。由上述預定端子不在範圍的可動構件160的下緣及前緣所構成的連續的突出緣部，在可動構件160因該可動構件160的凸輪部165、166、167的磨耗而從正規位置朝下方偏移的情況，其功能作為用來限制該可動構件160的預定量以上的下降的限制部168(參考第11圖(D))。具體來說，即使朝下方偏移 的可動構件160位於任何轉動角度位置時，可動構件160的限制部168的最下端部位抵接於抵壁115的上面而限制該可動構件160的預定量以上的下降。 When the movable member 160 is in the open position, the terminals in the terminal arrangement direction are not part of the range, specifically, the range outside the position of the accessory 140 outside the terminal arrangement range (hereinafter referred to as "predetermined terminal out of range"), The position of the lower edge of the movable member 160 covers the entire area in the front-rear direction than the lower edge of the range where the predetermined terminal is out of range. The front edge of the movable member 160 where the predetermined terminal is out of range has a position covering the entire area in the up-down direction, and protrudes forward more than the front edge of the range where the predetermined terminal is out of range. The continuous protruding edge portion formed by the lower edge and the leading edge of the movable member 160 where the predetermined terminal is out of range, the movable member 160 is moved downward from the regular position due to the wear of the cam portions 165, 166, and 167 of the movable member 160. In the case of an offset, the function serves as a restricting portion 168 for restricting the movable member 160 from falling more than a predetermined amount (refer to FIG. 11 (D)). Specifically, even if it shifts downward When the movable member 160 is located at any rotation angle position, the lowermost portion of the restricting portion 168 of the movable member 160 abuts on the upper surface of the abutment wall 115 to restrict the lowering of the movable member 160 by a predetermined amount or more.

預定端子不在範圍的限制部168的突出量，是將可動構件160的轉動過程的凸輪部165、166、167的軌跡的偏移(從正規軌跡起算的偏移)保持在允許範圍的程度的尺寸，是因應製品而適當設定。例如將上述突出量設定得較大的話，藉此可減少可動構件160的最大下降量。 The amount of protrusion of the limiting portion 168 where the predetermined terminal is out of range is a size that keeps the offset (offset from the regular trajectory) of the trajectories of the cam portions 165, 166, and 167 during the rotation of the movable member 160 within the allowable range. It is set appropriately according to the product. For example, if the amount of protrusion is set to be large, the maximum amount of lowering of the movable member 160 can be reduced.

在本實施方式，在端子排列方向形成可動構件160的限制部168的預定端子不在範圍，是端子不在範圍之中的一部分的範圍，也可取代該方式，將上述預定端子不在範圍作為上述端子不在範圍的全區域，在該端子不在範圍的全區域形成限制部。 In this embodiment, the predetermined terminal where the restricting portion 168 of the movable member 160 is formed in the terminal arrangement direction is out of range, and is a part of the range where the terminal is out of range. Instead of this method, the predetermined terminal out of range can be regarded as the terminal not in In the entire area of the range, a restricting portion is formed in the entire area where the terminal is not in the range.

這樣組成的本實施方式的連接器101，以下面方式使用且功能如下。 The connector 101 of this embodiment configured as described above is used in the following manner and functions as follows.

首先，將連接器101配置在電路基板(並未圖示)上的預定位置，將第1端子120的連接部126A、第2端子130的連接部137B、及配件140的焊接固定部146A分別與電路基板的對應部焊接連接並且固定。 First, the connector 101 is arranged at a predetermined position on a circuit board (not shown), and the connection portion 126A of the first terminal 120, the connection portion 137B of the second terminal 130, and the soldering portion 146A of the accessory 140 are respectively connected to Corresponding parts of the circuit board are soldered and fixed.

針對於安裝於電路基板的連接器101，在將可動構件160帶到如第11圖所示的豎立的開啟位置的狀態，將平型導體’的連接部分朝向前方***到收容部116內。該平型導體F’的連接部分，容易地***到：第1端子120的按壓臂部125與接觸臂部127之間、第2端子130 的按壓臂部135與接觸臂部137之間、及配件140的卡止臂部145與直狀臂部147之間。 For the connector 101 mounted on the circuit board, the connection portion of the flat conductor 'is inserted into the receiving portion 116 in a state where the movable member 160 is brought to the upright open position as shown in FIG. 11. The connection portion of the flat conductor F 'is easily inserted between the pressing arm portion 125 and the contact arm portion 127 of the first terminal 120 and the second terminal 130 Between the pressing arm portion 135 and the contact arm portion 137, and between the locking arm portion 145 and the straight arm portion 147 of the accessory 140.

接著使可動構件160朝向關閉位置轉動。當可動構件160開始從開啟位置的轉動時，首先第2凸輪部166與第2端子130的支承臂部136的上緣滑動接觸。藉由該滑動接觸讓可動構件160的轉動中心朝上方移動，結果，第1凸輪部165將第1端子120的受壓臂部124朝上方按壓移位，且第3凸輪部167將配件140的受壓臂部144朝上方按壓移位。與第1實施方式同樣地，第1凸輪部165及第3凸輪部167，在可動構件160開始轉動之後，分別與第1端子120的支承臂部126及配件140的支承臂部146之間具有間隙，而不會與該支承臂部126、146滑動接觸。於是上述第2凸輪部166與上述支承臂部136，會在承受較大接觸壓力的狀態滑動接觸，容易產生第2凸輪部166的磨耗。 Then, the movable member 160 is rotated toward the closed position. When the movable member 160 starts to rotate from the open position, first, the second cam portion 166 is in sliding contact with the upper edge of the support arm portion 136 of the second terminal 130. By this sliding contact, the center of rotation of the movable member 160 is moved upward. As a result, the first cam portion 165 presses and shifts the pressure receiving arm portion 124 of the first terminal 120 upward, and the third cam portion 167 moves the The pressure-receiving arm portion 144 is pressed and displaced upward. As in the first embodiment, the first cam portion 165 and the third cam portion 167 are provided between the support arm portion 126 of the first terminal 120 and the support arm portion 146 of the attachment 140 after the movable member 160 starts to rotate, respectively. Clearance without sliding contact with the support arm portions 126, 146. Therefore, the second cam portion 166 and the support arm portion 136 are brought into sliding contact with each other under a large contact pressure, and the second cam portion 166 is likely to be worn.

當可動構件160從開啟位置進行轉動時，如第12圖所示，第1凸輪部165抵接於支承臂部126的上緣且第3凸輪部167抵接於支承臂部146的上緣，在該時間點以後的轉動過程，所有凸輪部165、166、167對於支承臂部126、136、146的上緣滑動接觸。於是藉此減輕第2凸輪部166與上述支承臂部136的接觸壓力。在該轉動過程，凸輪部165、166、167將受壓臂部124、134、144進一步朝上方按壓。 When the movable member 160 is rotated from the open position, as shown in FIG. 12, the first cam portion 165 abuts the upper edge of the support arm portion 126 and the third cam portion 167 abuts the upper edge of the support arm portion 146. During the rotation process after this point in time, all the cam portions 165, 166, 167 are in sliding contact with the upper edges of the support arm portions 126, 136, 146. This reduces the contact pressure between the second cam portion 166 and the support arm portion 136. During this rotation, the cam portions 165, 166, and 167 press the pressure-receiving arm portions 124, 134, and 144 further upward.

當可動構件160進一步轉動而達到預定的轉 動角度位置時，上述受壓臂部124、134、144朝上方的移位量變成最大，結果，讓各按壓臂部125、135及卡止臂部145具有最大的移位量而朝下方移位。與第1實施方式同樣地，當可動構件160越過該轉動角度位置轉動時會產生卡嗒感。 When the movable member 160 further rotates to reach a predetermined rotation In the dynamic angular position, the upward displacement of the pressure-receiving arm portions 124, 134, and 144 becomes the maximum. As a result, each of the pressing arm portions 125, 135 and the locking arm portion 145 has the maximum displacement and moves downward. Bit. As in the first embodiment, when the movable member 160 is rotated beyond the rotation angle position, a click feeling is generated.

當可動構件160進一步轉動來到關閉位置時，如第13圖所示，凸輪部165、166、167各下緣(當在開啟位置時的前緣)被支承臂部126、136、146所支承，將可動構件160維持在上述關閉位置。結果如第13圖(A)、(B)所示，端子120、130的按壓部125A、135A從上方具有接觸壓力地接觸於對應的平型導體F’的連接電路部而電導通，接觸部127A、137A從下方具有接觸壓力地接觸於對應的平型導體F’的連接電路部而電導通。如第13圖(C)所示，維持著配件140的卡止臂部145的卡止部145A與平型導體F’的被卡止部F2’的前緣的卡止狀態，可確實防止平型導體F’脫落。 When the movable member 160 is further rotated to the closed position, as shown in FIG. 13, the lower edges (leading edges when in the open position) of the cam portions 165, 166, and 167 are supported by the support arm portions 126, 136, and 146. , The movable member 160 is maintained in the above-mentioned closed position. As a result, as shown in Figs. 13 (A) and (B), the pressing portions 125A and 135A of the terminals 120 and 130 have a contact pressure contacting the connection circuit portion of the corresponding flat conductor F 'from above and are electrically conductive. 127A and 137A are in electrical contact with the connection circuit portion of the corresponding flat conductor F 'from below with contact pressure. As shown in FIG. 13 (C), the locking state between the locking portion 145A of the locking arm portion 145 of the attachment 140 and the leading edge of the locked portion F2 'of the flat conductor F' is maintained, and the flat can be reliably prevented The type conductor F 'comes off.

如第11圖(D)、第12圖(D)、第13圖(D)所示，可動構件160，在正規位置，在從開啟位置至關閉位置之間的任一轉動角度位置，都在可動構件160的限制部168與殼體110的底壁115之間形成間隙，該可動構件160不會與底壁115滑動接觸。 As shown in FIG. 11 (D), FIG. 12 (D), and FIG. 13 (D), the movable member 160 is in the normal position and at any rotation angle position from the open position to the closed position. A gap is formed between the restricting portion 168 of the movable member 160 and the bottom wall 115 of the housing 110, and the movable member 160 does not come into sliding contact with the bottom wall 115.

可是，當反覆進行可動構件160的轉動操作而凸輪部165、166、167磨耗時，因應該磨耗量而該凸輪部165、166、167或可動構件160從正規位置朝下方偏 移。在本實施方式，在可動構件160從開啟位置起至關閉位置的任一轉動角度位置，當凸輪部165、166、167磨耗而可動構件160從正規位置朝下方偏移時，在預定端子不在範圍該可動構件160的限制部168的下端抵接於上述殼體110的底壁115的上面。於是，於是限制了可動構件160的預定量以上的下降，並且防止凸輪部165、166、167進一步的磨耗。如上述，限制部168的突出量，設定為將可動構件160的轉動過程的凸輪部165、166、167的軌跡偏移(從正規軌跡起算的偏移)保持在允許範圍的程度的尺寸，結果，讓可動構件160從正規位置的下降量不會過大，能良好地維持：可動構件160的操作感、平型導體F’與端子120、130的接觸壓力或電導通狀態、平型導體F’與配件140的卡止狀態等。 However, when the cam portions 165, 166, and 167 are worn out repeatedly by rotating operation of the movable member 160, the cam portions 165, 166, 167, and the movable member 160 are biased downward from the regular position due to the amount of wear. shift. In this embodiment, when the cam portion 165, 166, 167 wears and the movable member 160 shifts downward from the regular position at any rotation angle position of the movable member 160 from the open position to the closed position, the predetermined terminal is out of range. The lower end of the restricting portion 168 of the movable member 160 is in contact with the upper surface of the bottom wall 115 of the housing 110. Thus, the fall of the movable member 160 by more than a predetermined amount is restricted, and further wear of the cam portions 165, 166, 167 is prevented. As described above, the amount of protrusion of the restricting portion 168 is set to a size that keeps the track offset (offset from the normal track) of the cam portions 165, 166, and 167 of the cam member 165 during the rotation process, and as a result, So that the movable member 160 does not fall too much from the regular position, and can be maintained well: the operating feeling of the movable member 160, the contact pressure or electrical conduction state of the flat conductor F 'and the terminals 120, 130, and the flat conductor F' Engagement status with the accessory 140 and the like.
