  The flat conductor F has a connecting portion with the connector 1 at its front end (upper right edge forming a portion closer to the connector 1 in FIG. 1), and extends rearward (lower left in FIG. 1). However, in the figure, the part up to the position immediately behind the connecting part is shown, and the illustration behind it is omitted. In the present embodiment, the flat conductor F has a connection portion formed by removing the coating on the lower surface of the front end portion and exposing a connection circuit portion (not shown). On the upper surface of the front end portion of the flat conductor, a reinforcing sheet F1 is applied to improve the strength when connected to the connector.

  In the connecting portion of the flat conductor F, a locked portion F2 is formed by notches on both side edges in the width direction. A claw-shaped locking portion 45A formed on the metal fitting 40 described later enters and locks into the notched locked portion F2, thereby contributing to prevention of the flat conductor F from coming off.

  The connector 1 includes a housing 10 that receives the flat conductor F from the rear, two types of terminals 20 and 30 (first terminal 20 and second terminal 30) and metal fittings 40 arranged and held in the housing 10, and a housing 10. It has a shield plate 50 as a shield member to be held, and a movable member 60 supported by the housing 10, the terminals 20, 30 and the metal fitting 40. As will be described later, the movable member 60 is between an open position (see FIG. 6) that allows the flat conductor F to be inserted into the housing 10 and a closed position (see FIG. 9) that presses the flat conductor F. It is supported so that it can move with rotation.

  The first terminal 20, the second terminal 30, and the metal fitting 40 held by the housing 10 constitute a metal plate member that maintains a flat plate surface, and are arranged in a direction perpendicular to the plate surface. In the present embodiment, the first terminal 20 is used as a ground terminal, the second terminal 30 is used as a signal terminal, and the metal fitting 40 is locked to the flat conductor F to prevent the flat conductor F from coming off. Used as a locking member. In the present embodiment, the first terminal 20 and the second terminal 30 are arranged so that the two second terminals 30 are positioned between the adjacent first terminals 20. One metal fitting 40 is arranged on each side of the terminal arrangement range. The shapes of the first terminal 20, the second terminal 30, and the metal fitting 40 will be described in detail later.

  As is often seen in FIG. 4, the main body 51 has a substantially rectangular shape with the front-rear direction as the longitudinal direction when viewed from above, and extends in a range covering almost the entire area of the housing 10 in the front-rear direction. In the terminal arrangement direction, it extends in a range including two adjacent second terminals 30. As can be seen in FIGS. 3A and 4, the main body 51 has a front half (the lower half in FIG. 3A and the upper half in FIG. 4) from the latter half. Also, the width is narrow in the terminal arrangement direction, and a notch 51A is formed at the front end edge, and front end pieces 51B are formed on both sides of the notch 51A. As shown in FIG. 4 (A), the shield plate 50 has the front end piece 51B entering a second groove 63 (described later) of the movable member 60 from the rear (see also FIG. 6 (B)).

It has an elastic arm portion 52A that can be elastically displaced in the vertical direction, and a front contact portion 52B that extends outward (in a direction away from the main body portion 51) in the terminal arrangement direction from the front end of the elastic arm portion 52A. The rear contact piece 53 extends from the other side edge of the main body 51 at a position behind the front contact piece 52 of the main body 51. Similar to the front contact piece 52, the rear contact piece 53 extends in a downwardly inclined manner toward the front, and is elastically displaceable in the vertical direction, and from the front end of the elastic arm portion 53A in the terminal arrangement direction. A rear contact portion 53 </ b> B extending outward (in a direction away from the main body portion 51). The size of the rear contact piece 53 itself is substantially the same as the size of the front contact piece 52, and as can be seen in FIGS. 3A and 3B, the rear contact portion 53B of the rear contact piece 53 is the front contact portion 52B. It is located behind. Further, as seen in FIG. 3C, the rear contact portion 53B is located slightly above the front contact portion 52B.

  As seen in FIGS. 1, 2, and 4, one first terminal 20 as a ground terminal is provided between two shield plates 50 adjacent in the terminal arrangement direction when viewed from above. 2A and 2B, the front contact portion 52B of the front contact piece 52 of one shield plate 50 and the rear contact portion 53B of the rear contact piece 53 of the other shield plate 50 are the first One terminal 20 is brought into contact. Specifically, as often seen in FIG. 2 (B), the upper end surface (plate thickness) of the front half of the raised portion 26B formed on the lower arm portion 22 (see FIG. 2 (A)) of the first terminal 20. The front contact portion 52B of one shield plate 50 is in elastic contact with the upper surface (plate thickness surface) of the raised portion 26B, and the rear contact portion 53B of the other shield plate 50 is in elastic contact. As a result, all the shield plates 50 and all the first terminals 20 are electrically connected, and a good shielding effect can be obtained in the entire connector.

  As shown in FIG. 4, the shield plate 50 is press-fitted into the shield plate holding groove 14A of the upper wall 14 of the housing 10 from the front (upward in FIG. 4), and the press-fit protrusion 51C of the shield plate 50 holds the shield plate. The groove 14A is attached to the housing 10 by biting into the opposing inner wall surface (inner wall surface facing in the terminal arrangement direction) of the groove 14A. The shield plate 50 attached to the housing 10 is positioned so as to cover the two second terminals 30 from above, and as described above, as a ground terminal adjacent to the shield plate 50 on both sides of the shield plate 50. The first terminal 20 is electrically conductive by directly elastically contacting the upper end surface of the raised portion 26B of the first terminal 20 at the front contact portion 52B or the rear contact portion 53B.

  In the present embodiment, the shield plate 50 is positioned within the upper arm portion 21 of the first terminal 20 in the vertical direction. That is, as compared with the conventional connector in which the shield member is positioned above the upper arm portion of the terminal, the shield plate 50 overlaps with the upper arm portion 21 of the first terminal 20, that is, the plate of the shield plate 50. The height dimension of the connector 1 can be reduced by the thickness. Further, since the shield plate 50 is in contact with the first terminal 20 used as the ground terminal, a good shielding effect can be obtained.

  As shown in FIG. 1, the movable member 60 is made of an electric insulating material similar to that of the housing 10 as a member extending over almost the entire width of the housing 10.

  The movable member 60 is supported so as to be rotatable between an open position seen in FIG. 6 and an intermediate position seen in FIGS. 7 and 8 to a closed position seen in FIG. In FIG. 6, the rotation axis of the movable member 60 is located in the lower half portion of the movable member 60, and the lower half portion is accommodated in the open space 17 formed in the front portion of the housing 10. In FIG. 6, an upper half portion outside the open space 17 and projecting upward from the upper wall 14 of the housing 10 is an operation portion 61 for a user to rotate the movable member 60. It has become.

  In the lower half of the movable member 60 in FIG. 6, the first terminal 20, the second terminal 30, and the metal fitting 40 in the width direction of the movable member 60 (in the terminal arrangement direction and perpendicular to the paper surface in FIG. 6). The slit-shaped first groove 62 and the second groove 63 permitting the pressure receiving arm 24, the front end piece 51B, and the pressure receiving arm 44 to enter the first terminal 20, the shield plate 50, and the metal fitting 40, respectively. And the 3rd groove part 64 is penetrated and formed in the front and back. Accordingly, the groove widths of the first groove portion 62, the second groove portion 63, and the third groove portion 64 (the width between the groove inner surfaces in the direction perpendicular to the paper surface) are respectively the thickness of the first terminal 20 and the shield plate 50. The size is slightly larger than the width of the front end piece 51B and the thickness of the metal fitting 40. The first groove portion 62, the second groove portion 63, and the third groove portion 64 are provided with a first cam portion 65, a second cam portion 66, and a third cam portion 67 that connect the groove inner surfaces.

  The first cam portion 65 provided in the first groove portion 62 corresponding to the first terminal 20 in the terminal arrangement direction is a lower portion of the first groove portion 62 of the movable member 60 in the open position as seen in FIG. It is provided at a position, and is positioned between the pressure receiving arm portion 24 and the support arm portion 26 of the first terminal 20 in the vertical direction. When the movable member 60 is in the open position, the first cam portion 65 has an elongated shape in which a cross section perpendicular to the terminal arrangement direction extends in the front-rear direction as a whole, and the support arm portion of the first terminal 20 26 with a gap in the vertical direction between the upper edge of 26.

  The second half of the first cam portion 65 (the left half in FIG. 6A) is a guided portion 65A that is pivotally guided by the pressure receiving portion 24A of the first terminal 20 during the pivoting process of the movable member 60. The first half portion (the right half portion in FIG. 6A) is formed as a supported portion 65B supported from below by the support arm portion 26 of the first terminal 20 in the turning process and in the closed position. Yes. The guided portion 65A has an arc shape whose rear edge that is in sliding contact with the pressure receiving portion 24A is adapted to the pressure receiving portion 24A. The guided portion 65A extends forward from the lower front edge of the guided portion 65A, and the front end edge directly supported by the support arm portion 26 in the turning process and in the closed position forms an arc shape. ing. The rotation center of the first cam portion 65 is located in the region of the guided portion 65A when viewed in the terminal arrangement direction (direction perpendicular to the paper surface in FIG. 6A), and is a movable member. By rotating 60, the pressure receiving arm portion 24 of the first terminal 20 moves up and down elastically, but the left and right are restricted by the front and rear edges of the concave pressure receiving portion 24A and do not move.

  The second cam portion 66 provided in the second groove portion 63 corresponding to the second terminal 30 in the terminal arrangement direction is a lower portion of the second groove portion 63 of the movable member 60 in the open position as seen in FIG. It is provided at a position, and is positioned between the front end piece 51B of the shield plate 50 and the support arm portion 36 of the second terminal 30 in the vertical direction. When the movable member 60 is in the open position, the second cam portion 66 has a substantially square cross section perpendicular to the terminal arrangement direction, and the second cam portion 66 has a straight lower edge. Is supported from below by the upper edge of the support arm portion 36 of the second terminal 30. In addition, the lower front edge of the second cam portion 66 is a portion that is supported while being in sliding contact with the upper edge of the support arm portion 36 during the rotation of the movable member 60, and has an arc shape. Further, the rear edge of the upper portion of the second cam portion 66 is chamfered to form a beveled edge, so that interference with the front end piece 51B of the shield plate 50 can be avoided during the rotation of the movable member 60. Yes. Further, the front edge of the second cam portion 66 has a straight shape extending in the vertical direction. When the movable member 60 is brought to the closed position, it is extended in the front-rear direction and is lowered by the support arm portion 36. (See FIG. 9B).

  The third cam portion 67 provided in the third groove portion 64 corresponding to the metal fitting 40 in the terminal arrangement direction is located at the lower position of the third groove portion 64 of the movable member 60 in the open position as seen in FIG. It is provided and is positioned between the pressure receiving arm portion 44 and the support arm portion 46 of the metal fitting 40 in the vertical direction. When the movable member 60 is in the open position, the third cam portion 67 has a shape in which a cross section perpendicular to the terminal arrangement direction extends in the front-rear direction as a whole. The third cam portion 67 is inclined upward as the lower front edge is directed forward, and is inclined upward as the lower rear edge is directed rearward. A transition portion between the lower front edge and the lower rear edge ( The lower edge of the boundary portion forms a protruding edge that protrudes downward. The third cam portion 67 is supported on the support arm portion 46 from below by the protruding edge at the open position.

  Further, an edge projecting rearward at the upper portion of the third cam portion 67 has an arc shape, and comes into sliding contact with the pressure receiving arm portion 44 during the turning process of the movable member 60 (FIG. 7 ( C), 8 (C)). Further, the front edge of the third cam portion 67 has a straight shape extending in the vertical direction. When the movable member 60 is brought to the closed position, it is extended in the front-rear direction and is lowered by the support arm portion 46. (See FIG. 9C).

  When the movable member 60 is in the open position, the lower surface of the movable member 60 is in the restricting portion 15C of the bottom wall 15 of the housing 10 as shown in FIG. With a gap in the vertical direction.

  The connector 1 of this embodiment having such a configuration is used and functions in the following manner.

  First, the connector 1 is arranged at a predetermined position on a circuit board (not shown), and the connection part 26A of the first terminal 20, the connection part 36A of the second terminal 30, and the solder fixing part 47A of the metal fitting 40 are respectively provided on the circuit board. Connect and fix to the corresponding part of the solder.

  The connector 1 thus attached to the circuit board is brought to the open position where the movable member 60 is suspended as seen in FIG. 6, and the receiving portion 16 of the housing 10 is opened rearward (leftward in the figure). In this state, the flat conductor F can be inserted.

  Next, in a state where the movable member 60 is in the open position as seen in FIG. 6, the connecting portion (not shown) of the flat conductor F is inserted into the receiving portion 16 forward. In the first terminal 20, the space between the pressing portion 25 </ b> A of the pressing arm portion 25 and the contact portion 27 </ b> A of the contact arm portion 27 is slightly wider than the thickness of the connecting portion of the flat conductor F. The connecting portion of F is easily inserted. However, with respect to the metal fitting 40, the gap between the locking portion 45A of the locking arm portion 45 of the metal fitting 40 and the straight arm portion 47 is narrower than the thickness of the connecting portion of the flat conductor F. Therefore, the flat conductor F is lifted by elastically displacing the locking portion 45A at its front end and advanced to a predetermined position while widening the interval, and then the notched locked portion of the flat conductor F is obtained. The locking portion 45A enters F2 from above, whereby the flat conductor F is temporarily held.

  Even when the connecting portion of the flat conductor F is inserted as described above, the movable member 60 is in the open position, so that it is formed at the lower edge of the contact arm portion 27 that forms the rear half portion of the lower arm portion 22 of the first terminal 20. The contact portion 27 </ b> A is spaced from the bottom wall 15 of the housing 10 to form a gap.

  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 comes into sliding contact with the support arm portion 36 of the second terminal 30. As a result of this sliding contact, the rotational center of the movable member 60 moves upward. As a result, the first cam portion 65 serves as the pressure receiving arm portion 24 of the first terminal 20, and the third cam portion 67 serves as the pressure receiving arm portion 44 of the metal fitting 40. Is pushed upward and displaced. The first cam portion 65 and the third cam portion 67 have a gap between the support arm portion 26 of the first terminal 20 and the support arm portion 46 of the metal fitting 40 immediately after the start of the rotation of the movable member 60. The support arm portions 26 and 46 are not slidably contacted. That is, all reaction forces acting downward from the pressure receiving arm portions 24, 44 to the cam portions 65, 67 are received only by the sliding contact portion between the second cam portion 66 and the support arm portion 36. It will be. Therefore, the second cam portion 66 and the support arm portion 36 are slidably contacted with each other under a large contact pressure, and the second cam portion 66 is likely to be scraped.

  When the rotation of the movable member 60 from the open position proceeds, as shown in FIG. 7, the first cam portion 65 contacts the support arm portion 26 and the third cam portion 67 contacts the support arm portion 46. In the subsequent rotation process, all the cam portions 65, 66, 67 come into sliding contact with the support arm portions 26, 36, 46. Accordingly, the reaction force acting downward from the pressure receiving arm portions 24, 44 to the cam portions 65, 67 is applied to the sliding contact portions between all the cam portions 65, 66, 67 and the support arm portions 26, 36, 46. Therefore, the contact pressure between the second cam portion 66 and the support arm portion 36 is reduced accordingly. In this turning process, the cam portions 65 and 67 further press the pressure receiving arm portions 24 and 44 upward.

  Further, as shown in FIG. 8, when the movable member 60 rotates and the cam portions 65 and 67 press the pressure receiving arm portions 24 and 44 further upward, the displacement amount of the pressure receiving arm portions 24 and 44 is increased. As a result, the pressing arm portion 25 of the first terminal 20 and the locking arm portion 45 of the metal fitting 40 are displaced downward with the maximum amount of displacement.

  When the movable member 60 is further rotated and brought into the closed position, as shown in FIG. 9, the cam portions 65, 66, and 67 are respectively at the lower edges (the front edges when in the open position). The movable member 60 is maintained in the closed position by being supported by the support arm portions 26, 36, and 46. At this time, the upward displacement amount of the pressure receiving arm portions 24 and 44 by being pressed by the cam portions 65 and 67 is reduced as compared with the state shown in FIG. According to such a configuration, a click feeling is obtained when the cam portions 65, 66, 67 exceed the rotation angle position shown in FIG. 8 during the rotation operation of the movable member 60 toward the closed position. Can do.

  As described above, when the movable member 60 is brought to the closed position, the pressing arm portion 25 of the first terminal 20 is displaced downward with a sufficient amount of displacement, and the flat conductor F (not shown) is moved by the pressing portion 25A. Press from above. As a result, the contact portions 27A and 37A of the contact arm portions 27 and 37 and the connection circuit portion on the lower surface of the flat conductor F come into contact with each other with sufficient contact pressure and are electrically connected. Further, the locking arm portion 45 of the metal fitting 40 is displaced downward with a sufficient displacement amount, and the locking portion 45A enters deeply into the locked portion F2 of the flat conductor F, so that a sufficient locking amount is obtained. The locked state with the front edge of the locked portion F2 is maintained, and the flat conductor F is reliably prevented from coming off.

  Further, as shown in FIGS. 6D, 7D, 8D, and 9D, the movable member 60 can be moved from the open position to the closed position as long as it is in the normal position. In any of the rotation angle positions, 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 slidably contact the restricting portion 15C.

  In the connector 1 of the present embodiment, every time the movable member 60 is rotated between the open position and the closed position, the cam portions 65, 66, and 67 of the movable member 60 made of an electrical insulating material are made of a metal plate. Since the sliding contact with the support arm portions 26 and 36 of the terminals 20 and 30 or the support arm portion 46 of the metal fitting 40 is repeated, the cam portions 65, 66 and 67 may be scraped as a result. In particular, between the open position shown in FIG. 6 and the rotational rotation position shown in FIG. 7, the contact pressure between the second cam portion 66 and the support arm portion 36 of the second terminal 30 is as described above. Since it becomes large, the second cam portion 66 is likely to be scraped.

  When the cam portions 65, 66, and 67 are scraped in this way, the cam portions 65, 66, and 67 are shifted downward from the normal positions according to the shaved amount. If the displacement of the movable member 60 from the normal position is excessive, the trajectories of the cam portions 65, 66, 67 in the turning process of the movable member 60 are different from the normal trajectories. An operation feeling such as a click feeling that should be obtained cannot be obtained, and for example, it may be difficult to operate the movable member 60 or misidentify the position of the movable member 60. Furthermore, in the closed position, the amount of elastic displacement of the pressing arm portion 25 of the terminal 20 becomes small, and a sufficient contact pressure between the flat conductor F and the terminals 20 and 30 cannot be obtained, and the electrical conduction state becomes unstable. . Further, the amount of elastic displacement of the locking arm portion 45 of the metal fitting 40 is reduced, and a sufficient amount of engagement of the locking portion 45A of the metal fitting 40 with respect to the locked portion F2 of the flat conductor F cannot be obtained. It will not be possible to sufficiently prevent F from coming off.

  In this embodiment, when the cam portions 65, 66, and 67 are shaved and the movable member 60 is shifted downward from the normal position, the terminal is absent regardless of the position of the movable member 60 from the open position to the closed position. In a range, the restricting portion 15C of the bottom wall 15 of the housing 10 contacts the movable member 60 from below. Accordingly, the lowering of the movable member 60 by a predetermined amount or more is restricted, and further cam portions 65, 66, 67 are prevented from being scraped. As described above, the restricting portion 15C is formed with such a height that the deviation of the trajectory of the cam portions 65, 66, 67 in the turning process of the movable member 60 can be kept within an allowable range. The amount of lowering of the movable member 60 from the normal position does not become excessive, the operational feeling of the movable member 60, the contact pressure between the flat conductor F and the terminals 20 and 30, and the electrical conduction state, and the flat conductor F The locking state with the metal fitting 40 can be maintained satisfactorily.

  In the present embodiment, the restricting portion 15C of the housing 10 comes into contact with the movable member 60 only when the movable member 60 is lowered by a predetermined amount from the normal position. Even if the movable member 60 is in the normal position, if the restricting portion 15C is configured to contact the movable member 60, various problems occur due to dimensional errors and assembly errors of each member of the connector 1. obtain. For example, while the restricting portion 15C is in contact with the movable member 60 at the normal position, the cam portions 65, 66, 67 and the terminals 20, 30 of the movable member 60 and the support arm portions 26, 36, 46 of the metal fitting 40 are supported. An inadvertent gap is formed between the cam portions 65, 66, and 67 and the support arm portions 26, 36, and 46 may not be supported.

  On the other hand, in the present embodiment, when the movable member 60 is in the normal position, a gap is formed between the movable member 60 and the restricting portion 15C so as not to come into contact with the movable member 60. The restricting portion 15C comes into contact with the movable member 60 only when 60 is lowered by a predetermined amount from the normal position, that is, only when the cam portions 65, 66, 67 are shaved by a predetermined amount. Therefore, according to the present embodiment, even if a dimensional error or an assembly error occurs during the manufacture of the connector 1, the above-described problems cannot occur as long as these errors are within an allowable range. As a result, according to this embodiment, manufacture of the connector 1 becomes easy.

The main body 251 is provided so as to cover the two second terminals 230 as signal terminals from above. As shown in FIGS. 12B and 12C, the main body 251 is positioned within the upper arm 221 of the first terminal 220 in the vertical direction, and the connector 201 is the same as in the first embodiment. The reduction in height is planned.

  The front part of the main body 251 is narrower in the terminal arrangement direction than the other part, and the front contact piece 252 from one side edge of the front part and the rear contact piece 253 from the other side edge are shown in FIG. As is often seen in (C), each side edge is bent in the thickness direction and extends downward. As can be seen in FIG. 11 and FIGS. 12A and 12B, the rear contact piece 253 is located behind the front contact piece 252.

  As shown in FIGS. 12A and 12B, the contact pieces 252 and 253 extend downward to a position overlapping the raised portion 226B of the lower arm portion 222 of the first terminal 220 in the vertical direction, The plate surfaces at the lower ends (free ends) of the contact pieces 252 and 253 are in contact with the plate surface of the raised portion 226B of the first terminal 220 with contact pressure.
