  However, in the connector of Patent Document 1, the shield case (shield plate) extends to a range where the top plate portion covers the entire upper surface of the connector main body, and this top plate portion is connected to the upper surface of the connector main body. Since it descends in a parallel state and is attached to the connector main body, when the operator sees it from above, which is the mounting direction, the field of view is completely blocked by the top plate, and the connector main body cannot be visually confirmed. This tends to increase as the top plate is lowered and closer to the connector body. Thus, when the shield case is attached from above, the periphery of the seed case has the same direction and position as the peripheral edge of the connector body at almost the same time for any part in the circumferential direction without the inclination of the peripheral edges. It must be done and installation is not easy.

  In view of such circumstances, an object of the present invention is to provide an electrical connector for a flat conductor that can be easily attached even if it is a shield plate that is attached so as to cover the upper surface of the connector body.

  An electrical connector for a circuit board according to the present invention includes a connector body in which a housing made of an electrically insulating material holds a plurality of terminals arranged therein, and a shield plate attached to the connector body. Is attached to the circuit board so that the lower surface of the circuit board faces the circuit board.

In such an electrical connector for a circuit board, in the present invention, the shield plate includes a top shield portion that covers the top surface of the connector body, and a pivot fulcrum portion that has a pivot axis extending along the one end edge on the one end edge side of the connector body. And a locked portion that determines the rotation end position of the shield plate on the other end edge side, and the rotation fulcrum portion protrudes in the rotation axis direction at a position lower than the upper surface shield portion of the shield plate. And a fixing member attached to the housing of the connector main body, and a fulcrum support portion that rotatably supports the rotation fulcrum portion of the shield plate, and is engaged with the locked portion. A fulcrum support portion extending in a direction away from one end edge of the housing, and forming a space for entry of the rotating fulcrum portion below the fulcrum support portion. Seal to the body When installing the start of the plate, by the pivot point enters the aforementioned space formed support position so as to restrict the movement to the mobile and the other end side of the upper with respect to the rotating support part and to allow the introduction of the pivot point to, after entry of the pivot part to the space, when viewed from the direction perpendicular to the housing top surface, the pivot point and the fulcrum support is When the shield plate rotates to the position where the upper shield part is close to or in contact with the upper surface of the connector body at the fulcrum position after the shield plate is introduced to the fulcrum position of the pivot fulcrum part , the shield plate The locked portion of the plate and the locking portion of the housing or the fixing member are locked with each other by at least one of the elastic displacements.

According to the present invention having such a configuration, the shield plate is attached to the connector main body by a two-stage operation. As a first step, the rotation fulcrum portion of the shield plate automatically moves to the position of the fulcrum support portion by moving toward the one end edge of the connector body. At this time, for example, the shield plate is moved in the direction toward the other edge by bringing the rotation support portion closer to or in contact with the circuit board in an inclined posture so that the locked portion of the shield plate is lifted. The rotation support part automatically enters the lower part of the fulcrum support part and then reaches the fulcrum position, where the position is restricted and the rotation support state is enabled. Thereafter, as a second stage, the shield plate is rotated around the rotation fulcrum part in a state where the rotation fulcrum part is positioned by the fulcrum support part of the connector body. When the shield plate is rotated, the shield plate automatically comes to the mounting position, the locked portion is locked by the locking portion of the connector body, and this mounting position is maintained. As described above, in the present invention, since the shield plate is moved to the fulcrum support portion and rotated to the mounting position to be mounted (direct movement in the first stage, rotation in the second stage). Since the movement is performed only in one direction, it automatically moves toward the target position, and the position is automatically determined, so that it can easily reach the final mounting position of the shield plate, making the mounting operation very easy. Become.

  In the present invention, the locked portion is formed as an elastic portion extending to a position below the upper shield portion, and the elastic portion has elasticity in the contact / separation direction with respect to the other end edge of the housing, The locking portion protruding from the other end edge during rotation can be elastically deformed and locked by the amount of interference.

  When the shield plate in which the rotation support part is brought to the fulcrum position below the fulcrum support part in the first stage is rotated as the second stage, it is regulated by the fulcrum support part and the rotation support part is brought to the fulcrum position. In the maintained state, after the locked portion comes into contact with the locking portion of the connector body, the interference amount is overcome by elastic deformation, and the locking portion is locked, and the mounting of the shield plate is completed.

  In the present invention, the elastic portion has an operation portion extending laterally or above the side surface of the housing, above the front surface of the housing, forward of the front surface of the housing, or rearward of the rear surface, and is engaged by being pressed by the operation portion. It is preferable that the stopping portion can be released from the locking with the locking portion. Thus, by applying a pressing force to the operation portion, the locked portion is unlocked, and the shield plate can be removed simply by rotating the shield plate so as to be lifted. With this configuration, the shield plate can be easily removed even after it is attached.

  In the present invention, the flat conductor is inserted and connected to the housing from one end edge side, and the shield plate can be moved to the fulcrum position with the pivotal fulcrum portion guided by the side edge of the connected flat conductor. It can be made to become. By doing this, while obtaining a circuit board electric connector having a flat conductor connected to the connector body and having a shield plate, the flat plate already connected when moving the shield plate to the fulcrum position in the direction of the other end edge is obtained. By being guided by the side edges of the conductor, the position in the width direction of the shield plate can be automatically determined.

  In the present invention, the fixing member is a fixing bracket that is positioned outside the terminal arrangement range in the terminal arrangement direction, and has a solder portion that can be soldered to the circuit board on the lower edge. it can. By using the fixing member as a metal fitting, the strength of the fulcrum support portion itself and the locking portion itself can be increased while being thin and small. Furthermore, since the solder portion of the fixing metal is soldered to the circuit board, the strength against the force acting on the fulcrum support portion and the locking portion can be increased.

  In the present invention, when the shield plate is locked with the locking portion of the locked portion, the shield plate has a contact surface portion that contacts the circuit board adjacent to the locked portion, and the contact surface portion is a circuit. It is also possible to enable soldering with the substrate. For example, if it is definite that it is not necessary to remove the shield plate after it is attached to the connector body, the shield plate can be added to the connector body by locking the contact surface with the circuit board. Also, it is firmly held from the circuit board.

  Further, in the present invention, the shield plate has an elastic contact piece in which a part of the upper shield portion is cut and raised, and when the shield plate is rotated and locked to the locking portion at the locked portion. In addition, the elastic contact piece may be in elastic contact with a terminal corresponding to the elastic contact piece in the terminal arrangement direction. As a result, the shield plate functions as a part of the shield plate due to the contact between the elastic contact piece and the corresponding terminal, thereby improving the shielding effect against other terminals and the number of ground paths. The ground characteristics are also improved by increasing the distance and shortening the distance.

  Furthermore, in the present invention, the shield plate having the above-described characteristics can be obtained as a single unit as follows.

The shield plate has a top shield part that covers the top surface of the connector body, and a pivot point that has a pivot axis extending along the one end edge on the one end edge side of the connector body, and is pivotally guided by a fulcrum support part of the connector body. When, and a be-engaged portion for engaging portion and the locking of the connector body defines a rotational end positions of the shield plate at the other end edge, pivot point is a position below the upper surface shield portion of the shield plate provided droop part with is formed in a protrusion shape protruding to the rotation axis direction that extends to, provided in the fixed member attached to the housing or the housing of the connector body away from one edge of the housing When entering the space formed below the fulcrum support portion extending to the space, and after the rotation fulcrum portion enters the space, when viewed from a direction perpendicular to the upper surface of the housing, the fulcrum support portion and Located to the difference, the locked portion is formed in a resilient portion extending to a position below the upper surface shield portions, the contact and separation direction of the elastic against the locking portion of the connector body elastic portion And the locked portion can be locked with the locking portion after the rotation at the rotation fulcrum portion.

  As described above, according to the present invention, when the shield plate has the rotation fulcrum portion located on the one end edge side of the connector main body and the locked portion located on the other end edge side, First, it is moved along the surface of the circuit board to bring the pivot fulcrum part to the position of the fulcrum support part of the connector main body, and then the shield plate is pivoted around the pivot fulcrum part to be covered. Since the locking part is locked to the locking part of the connector body and the mounting position is maintained, the operation is performed in two stages, but the positional relationship between the shield plate and the connector is easy in the first stage. Since it can be visually observed and is automatically brought into the mounting position relationship by rotation in the second stage, the mounting operation becomes very simple.

  The housing 10 is made of an electrical insulating material, and the arrangement direction of the terminals 20 and 30 is the width direction of the flat conductor F, and the planar shape is rectangular. Here, assuming that the insertion / extraction direction of the flat conductor F parallel to the surface of the circuit board and perpendicular to the width direction is the front-rear direction, the housing 10 is rearward and rearward in the rear part, which is the lower left part in FIG. An opening 11 that opens upward is formed. The opening 11 is formed in the width direction so as to extend beyond the arrangement range of the terminals 20 and 30 to the positions of the fixing fittings 40 located on both sides thereof.

  In the housing 10, two types of terminal grooves 12 and 13 corresponding to the two types of terminals 20 and 30 are alternately formed in the terminal arrangement direction. The terminals 20 and 30 are both formed as slits having a groove width corresponding to the plate thickness of the terminals 20 and 30 because the terminals 20 and 30 are formed and shaped while maintaining a flat plate surface of the metal plate. . The terminals 20 and 30 are arranged in the plate thickness direction, and the terminal groove has a groove width corresponding to the plate thickness in this direction.

  Since the present invention does not have a feature in the terminal shape, a detailed description is omitted and only a brief description is given. Both terminals 20 and 30 are fixed with an elastic arm formed with a contact portion that contacts the flat conductor from below and a connection portion that is positioned below the elastic arm and soldered to the circuit board. The arm and the support arm formed integrally with a support portion that is positioned above the elastic arm and rotatably supports the movable member. One terminal 20 is press-fitted into the corresponding terminal groove 12 from the rear, and the connecting portion 21 protrudes rearward from the rear edge of the housing 10 as seen in FIG. Note that, as seen in FIG. 6 described later, the contact portion 22 is located in front of the connection portion 21, and the support portion 23 is located above the contact portion 22. The terminal 20 is inserted into the terminal groove 12 from behind, and is press-fitted and held at the upper edge and the lower edge of the front end portion of the terminal 20. Further, the fixed groove 21A formed in the front portion of the connecting portion 21 is also fitted and held on the rear edge of the bottom wall of the housing (see FIG. 6). As shown in FIG. 1, the other terminal 30 is inserted into the terminal groove 13 from the rear, and is press-fitted and held in the terminal groove 13 at the upper edge and the lower edge of the front end portion of the terminal 30. The connection portion 31 protrudes forward from the front edge of the housing (see also FIG. 6), and the contact portion 32 is located behind the contact portion 22 of the one terminal 20. The terminal 30 may not have a support arm.

  As shown in FIG. 1, the fixing bracket 40 is formed as a fixing member for firmly fixing the housing 10 to the circuit board, and is held by the housing 10 so as to be fixed to the corresponding portion of the circuit board by soldering. It has become. The fixing bracket 40 is made by forming a metal plate thicker than the terminals 20 and 30 and maintaining the flat plate surface as it is, as in the case of the terminals 20 and 30. As shown in FIG. 1, the fixing metal fitting 40 is press-fitted into a metal fitting groove 14 formed in the width direction in the vicinity of both ends of the housing 10 so as to penetrate the front part of the housing 10 in the front-rear direction. Has been. The fixing bracket 40 will be described later again.

  A movable member 50 is rotatably supported on the housing 10. The movable member 50 is made of an electrically insulating material, has a substantially plate shape, and has a width over the entire width of the opening 11 of the housing 10 as seen in FIGS. 1 (A) and 1 (B). ing. Although not shown in the drawing, the movable member 50 is provided with end shaft portions projecting at both ends in the width direction, engaged with the corresponding housing shaft support portion, and the rotation support portion of the terminal 20 described above. In combination with the engagement, the support is rotatably supported. The movable member 50 is pivoted between an open position in the vertical position shown in FIG. 1 (A) and a closed position in the horizontal position shown in FIG. 2 (B). The lower part of the movable member 50 and the whole in the closed position fit in the space of the opening 11 of the housing 10.

  A shield plate 2 is attached to the connector body 1 as shown in FIG. The shield plate 2 is made by punching and bending a metal plate. In addition to the upper shield portion 3 that covers the upper surface of the connector main body 1, in this embodiment, the front and side surfaces of the connector main body 1 are used. The front shield part 4 and the side shield part 5 are also provided.

  The upper shield part 3 is provided with elastic contact pieces 3A which are cut and raised at two positions in the width direction, and the cut and raised parts are slightly bent downward and have elasticity up and down. ing. The elastic contact piece 3A is in elastic contact with the terminals arranged at corresponding positions in the width direction from above. The terminal with which the elastic contact piece 3A comes into contact is used as a ground terminal.

  The shield plate 2 has a front shield part 4 formed at a position spaced from the front end face of the housing 10, and the elastic part 6 extends laterally from both widthwise ends of the front shield part 4. I'm out. The elastic portion 6 is bent in a crank shape in the plate thickness direction, and is close to or abuts the front end surface 2A of the notched portion in which the top shield portion 3 and the side shield portion 5 are notched on the front end side portion. Yes. The elastic portion 6 protrudes laterally from the outer surface of the side shield portion 5 in the width direction, and this protruding portion forms an operating portion 6A, and receives an operating force from the rear on the rear surface, An elastic displacement is caused to the elastic portion 6. The operation portion 6A may protrude upward rather than laterally, or may be provided so as to extend forward of the front surface of the housing or rearward of the rear surface of the housing.

  As seen in FIGS. 3 (A) and 3 (B), a bent piece extends downward from the lower edge of the elastic portion 6 along the surface of the circuit board. A contact surface portion 6B that contacts the surface is formed. The contact surface portion 6B can be soldered to the circuit board when necessary. Further, the bent portion adjacent to the base portion of the contact surface portion 6B has a curved surface and forms an introduction portion 6C.

  Further, the elastic portion 6 is formed with a window-like locked portion 6D at a position above the contact surface portion 6B.

  The rear end of the side shield portion 5 of the shield plate 2 has a notch at the upper edge, is bent inward in the width direction, and extends in the width direction along the rear surface of the connector body 1. 7 is formed. Bending in the width direction to form the rotation fulcrum part 7 brings about an effect of improving the strength of the shield plate 2. The interval between the two rotation fulcrum portions 7 extending in the direction approaching each other inward from both side edges in the width direction is set substantially equal to the width of the flat conductor F. A line connecting the two rotation fulcrum portions 7 forms a rotation axis of the shield plate 2.

  Next, the fixing bracket 40 described above will be described again, including the engagement with the shield plate 2. As shown in FIG. 4, the fixing bracket 40 made by maintaining a flat plate surface of the metal plate has an immersive portion 41 formed on the upper edge side in the front-rear direction, and is a front portion of the immersive portion 41. Is a through-fixing portion 42, and the rear portion is a support arm portion 43. In the front-rear direction, the lower edge in the range extending over both the immersive portion 41 and the support arm portion 43 forms a solder fixing portion 46 that is in contact with the circuit board and fixed by soldering.

  The immersive portion 41 forms a space for accommodating the ear-shaped protrusion F1 of the flat conductor F, and the vertical trailing edge 41A of the immersive portion 41 can be locked with the rear edge of the protruding portion F1. When the flat conductor F is inadvertently pulled backward, it prevents the extraction. Whether or not the protruding portion F1 is housed in the immersive portion 41 at a regular position is confirmed by visual observation through the window portion 8 formed in the corresponding portion of the shield plate 2 (see FIG. 2).

  The penetration fixing portion 42 is press-fitted into the metal groove 14 formed in the front portion of the housing 10, and a protrusion 42 </ b> A formed on the upper edge bites into the upper surface of the groove of the housing to prevent the removal. The front end portion of the penetration fixing portion 42 forms a locking portion 42B that is tapered forward and has a rounded edge. Since the engaging portion 42B protrudes forward from the front end face 10A of the housing 10 and the front end face 2A of the shield plate 2, the elasticity of the shield plate 2 located close to or in contact with the front end face 2A. It has the part 6, the front-back direction (the thickness direction of the elastic part 6), and the amount of interference. The locking portion 42B having this amount of interference is positioned through the window-shaped locked portion 6D formed in the elastic portion 6 when the shield plate 2 is completely attached to the connector body 1 (see FIG. 3 (A) and (B)).

  The support arm portion 43 located rearward of the immersion portion 41 is opened and cut out rearward and downward, and is configured to extend rearward at the upper portion of the fixing bracket 40. The support arm 43 forms a space in which the cut-out portion accommodates the rotation fulcrum portion 7 of the shield plate 2, and the upper edge thereof forms the upper support edge 44 </ b> A with respect to the position of the rotation fulcrum portion 7 and the front edge. Respectively form a front support edge 44B, and both edges 44A and 44B form an inverted L-shaped fulcrum support portion 44. Further, a restricting projection 45 is provided at a rear position of the upper support edge 44A to limit the upper support edge 44A. Thus, the fulcrum support portion 44 receives the turning fulcrum portion 7 of the shield plate 2 from the rear in the cut-out portion, and regulates the upper and front positions at the upper support edge 44A and the front support edge 44B, respectively. Thus, when the shield plate 2 is rotated, the corner of the support edges 44A and 44B is defined as a fulcrum position P, and the position of the rotation fulcrum part 7 is determined.

  Next, the relationship between the shield plate 2 and the terminal 20 will be described. FIG. 6 is a cross-sectional view at the position of one terminal 20, showing when the shield plate 2 is completely attached to the connector body 1. As described above, the upper and lower sides of the elastic arm on which the contact portion 22 is formed have the support arm on which the support portion 23 is formed and the fixed arm on which the connection portion 21 is formed. It is press-fitted and held in the terminal groove 12 at the connected front end. The flat conductor F is inserted between the contact portion 22 and the support portion 23, and the contact portion 22 contacts the lower surface of the flat conductor F.

  A recess 23A is formed at the lower edge of the support portion 23, and the shaft portion 51 of the movable member 50 is rotatably supported here. As described above, the movable member 50 has an end shaft portion at the end portion in the width direction, and the end shaft portion is supported by the shaft support portion of the housing. Even in the intermediate range, the shaft portion 51 is rotatably supported by the terminal 20. In the movable member 50, a slit portion 52 is formed at a position corresponding to the terminal 20 in the terminal arrangement direction at the lower portion in the open position in FIG. 1A and the right portion in the closed position in FIG. The shaft portion 51 is provided so as to connect the opposing groove inner surfaces of the portion 52. Thus, the movable member 50 receives the support portion 23 of the terminal 20 through the slit portion 52, and the shaft portion 51 of the movable member 50 is received in the recess 23 </ b> A of the support portion 23. The other terminal 30 is not shown, but may or may not have a similar support portion.

  The two elastic contact pieces 3A formed on the upper shield part 3 of the shield plate 2 are in elastic contact with the upper edge of the support part 23 of the terminal 20 at a position corresponding to the elastic contact piece 3A in the terminal arrangement direction. Accordingly, the elastic contact piece 3 </ b> A is contacted among the plurality of terminals 20. The terminal 20 is used as a ground terminal.

  In the connector of this embodiment configured as described above, the shield plate is attached to the connector main body and used in the following manner.

  (1) First, the connector body 1 is mounted on a circuit board. In this attachment, after the connector main body 1 is arranged at a predetermined position on the circuit board, the solder fixing portion 46 of the fixing bracket 40 is soldered to the corresponding portion, and the connection portions 21 and 31 of the terminals 20 and 30 are soldered to the corresponding portion. This is done by connecting them.

  (2) Next, after the movable member 50 of the connector main body 1 is brought to the open position in the vertical position shown in FIG. 1A, the flat conductor F is inserted through the opening 11 of the connector main body 1 and the terminal 20 , 30 are arranged on the contact portions 22 and 32, and then the movable member 50 is rotated to the closed position in the horizontal position shown in FIG. The movable member 50 presses the upper surface of the flat conductor F downward on the lower surface side at the closed position, and increases the contact pressure between the flat conductor F and the contact portions 22 and 32 of the terminals 20 and 30. The movable member 50 locks a portion (not shown) of the housing and maintains the closed position. The movable member 50 in this closed position is housed in the opening 11 of the housing 10 and has an upper surface as shown in FIG. 1 and as seen in FIG. 6 showing the same state. The same level as that of the upper surface is formed.

  (3) The shield plate 2 is then attached to the connector body 1 to which the flat conductor F is connected after being attached on the circuit board. The shield plate 2 is attached in two stages. In the first stage, as shown in FIG. 4, the tilting posture is made by raising the front end side of the shield plate 2, and the rotation fulcrum portion 7 on the rear end side is brought into contact with or close to the surface of the circuit board. Place it at the position where it was placed. At this time, the two rotation fulcrum portions 7 of the shield plate 2 facing each other in the width direction, that is, the direction perpendicular to the paper surface in FIG. 4 are in contact with or close to the side edge of the flat conductor F. In this state, the shield plate 2 is moved forward. During the movement, the two rotating fulcrum portions 7 facing each other are guided by the flat conductor F so that the flat conductor F is sandwiched between the side edges thereof, so that the shield plate 2 is displaced in the width direction. Without moving forward toward the connector body 11.

  (4) When the forward movement of the shield plate 2 proceeds, the rotation fulcrum portion 7 is a fulcrum support portion 44 formed below the support arm portion 43 of the fixture 40 supported by the connector body 1. Enter into the space. The rotation fulcrum portion 7 abuts on the front support edge 44B of the fulcrum support portion 44 and remains at the most advanced position.

  (5) After that, as a second step, the front end of the shield plate 2 is pushed downward to rotate the shield plate 2 with the rotation fulcrum portion 7 as the rotation axis. By this rotation, the rotation fulcrum portion 7 tries to rise, but after a slight rise, the upper support edge 44A of the fulcrum support portion 44 prevents further rise. Thus, the rotation fulcrum portion 7 advances with the corner portion regulated by both the front support edge 44B and the upper support edge 44A as a fulcrum position P.

  (6) When the rotation progresses and the elastic part 6 of the shield plate 2 comes into contact with the locking part 42B from which the fixing bracket 40 protrudes, the elastic part 6 is formed as a curved surface at the lower part. The introduction portion 6C smoothly moves downward, the elastic portion 6 is elastically bent forward by the reaction force from the locking portion 42B, and further moves downward while sliding on the front edge of the locking portion 42B. When the downward movement proceeds and the locked portion 6D formed in a window shape on the elastic portion 6 reaches the locking portion 42B, the elastic portion 6 is released from the elastic bending and becomes free. The locking portion 42B enters the locking portion 6D, and the locked portion 6D is prevented from moving upward by locking with the locking portion 42B. Thus, the shield plate 2 is attached to the regular position and ensures its position. In this attached state, the elastic contact piece 3A formed on the top shield part 3 of the shield plate 2 contacts the support part 23 of the corresponding terminal 20, and the shield plate 2 is grounded through the corresponding terminal 20. . In this case, the corresponding terminal 20 provides a shielding function for the terminals on both sides thereof.

  After the shield plate 2 is attached, when a situation that requires removal occurs, the operation portion 6A of the elastic portion 6 is pushed forward to elastically displace the locked portion 6D to release the locking portion 42B. Then, lift it up and remove it. Further, when no removal is necessary, the contact surface portion 6B can be soldered to the circuit board to increase the attachment strength.

  The present invention is not limited to the embodiment shown in FIGS. 1 to 6 and various modifications can be made. In the example of FIGS. 1 to 6, the pivot fulcrum portion 7 of the shield plate 2 and the fulcrum support portion 44 of the fixing bracket 40 are fixed to the rear end side of the connector body 1 and to the locked portion 6D of the shield plate 2. Although the locking portion 42B of the metal fitting 40 was on the front end side, as shown in FIGS. 7A and 7B which are perspective views from the rear and the front, these front-rear relations may be reversed. .

  Further, in the above-described embodiment, the rotation axis of the shield plate is parallel to the rear end edge or the front end edge of the connector body. However, the present invention is not limited to this, and one side edge side of the connector body. It is also possible to attach the shield plate by rotating toward the other side edge.

  The mating connector connected to the connector of the present invention may be not only a flat conductor but also a normal cable or a mating connector. In this embodiment, the terminal is a so-called front flip type. However, the terminal may be a back flip type, and the terminal type is not limited.

  Furthermore, in the above-described embodiment, the fulcrum support portion and the locking portion for the shield plate are provided in the fixing bracket, but these can be provided in the housing 10 instead.
