Description

  The present invention relates to an electrical connector for a flat conductor.

  As the flat conductor, a flexible substrate (FPC), a flat cable, and the like are known. Such flat conductors are often connected to electrical connectors attached to circuit boards. As a connector to which such a flat conductor is connected, for example, there is a connector disclosed in Patent Document 1.

  In the connector disclosed in Patent Document 1, a receiving recess for receiving the FPC tip connection portion is formed in the housing, and the FPC is inserted and disposed on the contact portions of a plurality of terminals arranged in the receiving recess. Is done. The terminals are made while maintaining the flat surface of the metal plate, and a plurality of terminals are arranged so that the flat surfaces are parallel to each other. A cover housing for opening and closing the housing is rotatably provided in the receiving recess of the housing, and when the cover housing is rotated to the closed position, the FPC is pressurized by the cover housing to the contact portion. Electrical connection is made with a predetermined contact pressure.

The cover housing as a pressure member is provided with shaft-shaped cylindrical protrusions at both ends of the cover housing in the terminal arrangement direction, and the arc-shaped recess formed shallowly on a metal reinforcing plate attached to the housing. A cylindrical projection is supported rotatably. Thus, the cover housing is rotatable between an open position that allows insertion of the FPC and a closed position that pressurizes the FPC.
JP 2006-196424 A

  In the connector of Patent Document 1, the cover housing is supported so that the center of rotation is a fixed position only by a cylindrical columnar protrusion protruding in the same direction from the end in the terminal arrangement direction. In the terminal arrangement range between both cylindrical protrusions, no rotation is supported from the housing side. In addition, the arc-shaped concave portion of the metal reinforcing plate that supports the cylindrical protrusion is formed shallow and supports the lower surface of the cylindrical protrusion.

  Since this type of connector is made with flat terminals, the pitch between the terminals can be reduced, so a large number of terminals are provided. As a result, the cover housing as a pressure member has a terminal arrangement. Often the width dimension in the direction increases. Therefore, it is necessary when the cover housing is in the closed position or when the external force having a lateral component is inadvertently received when the cover housing is moving toward the closed position, for example, when the cover housing is moved to the closed position. When the lateral force is applied as described above, the position becomes unstable, and the cylindrical protrusion may come off the shallow arc-shaped recess.

  In view of such circumstances, an object of the present invention is to provide an electrical connector for a flat conductor that does not come off even when a pressure member receives a lateral external force at a closed position.

  In the flat conductor electrical connector according to the present invention, a plurality of terminals made by maintaining a flat plate surface of a metal plate are arranged and held by a housing with the plate surfaces parallel to each other, and each terminal is connected to the housing. A support arm and a contact arm extending from a base portion on which a mounted portion for attachment is provided, and the support arm and the contact arm extend with a space between each other, and from the outside of the housing at the space A pressure member that can receive the tip of the inserted flat conductor and can rotate between an open position that facilitates reception of the flat conductor and a closed position that presses the flat conductor includes the support arm. The pressure support member increases the contact pressure between the flat conductor and the contact portion of the contact arm by rotating to the closed position.

  In such an electrical connector for a flat conductor, in the present invention, a locking member made of a metal plate and having a plate surface parallel to the terminal is attached to the housing, and is parallel to the plane of the flat conductor. A locking protrusion protruding in a direction intersecting the surface, and the locking protrusion extends beyond a position corresponding to the rotation center of the pressure member in the protruding direction of the locking protrusion. The pressurizing member is formed with a receiving cavity for receiving the locking projection in the closed position, and the receiving cavity has a cross section in a plane parallel to the plane of the flat conductor. The inner wall surface is formed along the cross-section of the locking projection in a range longer than half of the peripheral surface.

  In the flat conductor electrical connector having such a configuration, when the pressure member is in the closed position, the locking projection of the locking member enters the receiving space, and the locking projection is the surface of the flat conductor. It is located beyond the position corresponding to the center of rotation in a direction perpendicular to the center. Thus, even when the pressure member receives an external force in the lateral direction (longitudinal direction of the flat conductor) at the closed position, the wall surface forming the receiving space of the pressure member abuts on the locking protrusion of the locking member. Therefore, the pressure member does not come off. Further, since the locking member is made of metal, sufficient strength is secured to prevent the pressing member from coming off even if the locking protrusion is small. Further, when the pressure member is in the closed position, the locking projection is positioned within the thickness range of the pressure member in a direction perpendicular to the plane of the flat conductor. Therefore, the connector does not increase in size in the same direction due to the provision of the locking projection. In addition, the receiving space has an inner wall surface that extends along a range longer than half of the peripheral surface of the locking projection, and the reduction in the strength of the pressure member due to the formation of the receiving space is small. No effect.

  The receiving cavity can be a recess. Since the bottom wall is present in the recess, it is possible to minimize a decrease in strength of the pressure member due to a decrease in the thickness of the pressure member. In addition, when there is no problem in strength, the receiving space may be formed so as to penetrate in the direction in which the locking projection extends. As a result, the locking protrusion can be formed to extend longer by the amount of penetration of the receiving recess, so that a large contact area between the wall surface forming the receiving space and the locking protrusion can be secured. That is, the locking amount of the locking projection can be increased.

  The locking member can be provided adjacent to at least the terminal at the end in the arrangement direction of the terminals. The locking member can also be provided within the arrangement range of the terminals. As described above, the locking members are also provided within the arrangement range of the terminals, and the locking protrusions of the locking members are engaged with the wall surfaces forming the receiving spaces for the pressure members at the positions of the locking members. By stopping, it is possible to prevent the pressure member from coming off over the entire arrangement range of the terminals, so that the pressure member becomes more difficult to come off.

  In the present invention, as described above, the locking member made of the metal plate is disposed together with the terminal, and the locking projection formed on the locking member is moved to the receiving space of the pressure member in the closed position. Since it has entered beyond the position corresponding to the rotation center of the pressure member, the locking protrusion fits within the thickness range of the pressure member, and the connector is closed without increasing the height of the connector. The detachment of the pressure member at the position can be reliably prevented. In addition, since the receiving space has an inner wall surface along the peripheral surface of the locking projection in a range longer than half of the peripheral surface of the locking projection, the strength of the pressure member at this portion There is almost no decline. Furthermore, since the locking member is made of a metal plate, the strength can be sufficiently ensured without enlarging the locking protrusion itself.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The terminal receiving groove 12 extends parallel to the paper surface, that is, parallel to the plate surface of the terminal 20. The terminal receiving groove 12 has a groove width (width in a direction perpendicular to the paper surface) that is substantially the same as the thickness of the terminal 20 formed while maintaining the plane of the metal plate, and is in a direction perpendicular to the paper surface. A plurality of terminals are formed at intervals with the number of terminals. The space between the terminal receiving grooves 12 is provided in the left region of the housing 10 so as to penetrate the paper surface in a direction perpendicular to the paper surface. In this space, the flat conductor P can be inserted from the left side. The insertion port 11 is formed.

  The connecting portion 24 is positioned adjacent to the base portion 22 of the attached portion 21, and connects the base portion 22 to the support arm 25 and the connecting arm 26. That is, the support arm 25 and the contact arm 26 extend leftward from the connecting portion 24.

  The support arm 25 extends to the left and has a tip end outside the terminal receiving groove 12, and a concave support member 25 </ b> A facing downward is formed on the lower edge of the tip end. Further, a contact portion 26A that protrudes upward is formed at the tip of the contact arm 26 that is substantially parallel to the support arm 25 and extends substantially the same length below the support arm 25.

  The flat conductor P connected to the connector 1 having such a structure has a supporting arm so that a connection circuit portion (not shown) formed on the lower surface of the tip portion is in contact with the contact portion 26A of the terminal 20. 25 and the contact arm 26 are inserted into the insertion slot 11.

  As shown in FIG. 3B, at the position between the terminal 20 at the end in the terminal arrangement direction and the locking member 30 adjacent to the terminal 20, the lower portion of the housing 10 is left with respect to the upper portion. The lower part extends to the same position as the lower part of the housing 10 at the terminal position in the terminal arrangement direction shown in FIG. A U-shaped curved portion 15 is formed on the left end side of the housing 10 so as to face upward. When the flat conductor connected to the connector 1 has an ear portion on the side edge, the curved portion 15 is formed. Accommodates the ears of a flat conductor.

  As shown in FIG. 3C, the housing 10 is formed such that the lower portion extends leftward with respect to the upper portion at a position corresponding to the locking member 30 in the terminal arrangement direction. In the lateral direction, the terminal 20 extends to substantially the same position as the tips of the support arm 25 and the contact arm 26 of the terminal 20. A holding opening 16 for holding the locking member 30 is formed in the housing 10. The holding opening 16 is partially opened on the upper, lower and left sides of the housing 10.

  The locking member 30 extends straight in the right direction and is pressed into the holding opening 16 from the left side. The left end of the arm portion 31 is parallel to the plane of the flat conductor P. A locking projection 32 that protrudes upward in a crossing direction, in a direction perpendicular to the illustrated example, a contact surface portion 33 extending leftward from the lower portion of the locking projection 32, and upward from the left end of the contact surface portion 33. It has a restricting portion 34 extending in parallel with the locking projection 32. The locking protrusion 32, the contact surface portion 33, and the restricting portion 34 form the U-shaped curved portion 35.

  The arm portion 31 has a tapered tip (right end) and is easy to enter at the time of press-fitting into the holding opening 16, a protrusion 31A is formed on the upper edge and bites into the inner surface of the holding opening 16, It is designed to be held firmly.

The contact surface portion 33 has a lower edge 33A in the height direction that is substantially at the same level as the bottom surface of the housing 10 and is in contact with the circuit board when the connector 1 is disposed on the circuit board (not shown). It is in. As described above, the upper edge of the contact surface portion 33 forms a U-shaped curved portion 35 together with the opposing edges of the locking projection 32 and the restricting portion 34. When viewed from the terminal arrangement direction, the curved portion 35 has substantially the same shape at substantially the same position as the curved portion 15 of the housing 10, and the flat conductor connected to the connector 1 has an ear portion on the side edge. In this case, the bending portion 35 together with the bending portion 15 accommodates the ear portion of the flat conductor. Note that the contact surface portion 33 is formed with a dimension that is substantially equal to the wall thickness of the lower portion of the housing 10 in the height direction, and the curved portion 15 of the housing 10 is slightly larger than the curved portion 35 of the locking member 30 in the lateral direction. Has been.

  The connector 1 is provided with a pressure member 40 in order to increase the contact pressure between the connection circuit portion of the flat conductor P and the contact portion 26 </ b> A of the terminal 20. The pressure member 40 is made of the same synthetic resin as the housing 10. As shown in FIG. 3A, the pressure member 40 is formed with an operation portion 41 for rotating operation at the upper portion of the pressure member 40 and a groove portion 42 at the lower portion in the terminal arrangement range. The groove 42 is formed in a slit shape at a position corresponding to each terminal 20 in the arrangement direction of the terminals 20 so that the tip of the support arm 25 of the terminal 20 penetrates. In each groove portion 42, a cam portion 43 is formed in an island shape at the lower end portion of the groove so as to connect the inner surfaces of the groove portions 42. In the open position, the cam portion 43 has an arc-shaped side facing the inside of the groove portion 42, and the opposite side forms a plane parallel to the horizontal plane. In the pressure member 40, the arc-shaped portion of the cam portion 43 is guided by the rotation support portion 25A of the terminal 20, and the rotation center O, that is, the center of the arc-shaped portion is used as an axis. It is freely rotatable between an open position shown in FIG. 4C and a closed position shown in FIGS.

  At a position corresponding to the locking member 30 in the terminal arrangement direction, the pressing member 40 is formed as a recess allowing the locking protrusion 32 to enter as shown in FIG. 4C in the closed position. It has a receiving cavity 44. The receiving space 44 is formed to have a depth that is larger than the dimension in which the locking protrusion 32 protrudes upward from the upper edge of the arm 31.

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

<At the time of assembly>
(1) First, the housing 10, the predetermined number of terminals 20, the locking member 30, and the pressure member 40 are prepared.
(2) The terminal 20 is inserted and attached to the terminal receiving groove 12 of the housing 10 from above. The attached portion 21 of the terminal 20 is press-fitted into the holding recess 14, and the protrusion 21 </ b> A bites into the inner surface of the holding recess 14, thereby preventing the removal. In this state, most of the contact arm 26 of the terminal 20 is accommodated in the intermediate opening 12 </ b> A of the housing 10. The connecting portion 23 of the terminal 20 comes to a position where the lower edge 23A is at the same level as the lower surface of the housing 10 (see FIG. 3A).

  (3) Next, the pressure member 40 is assembled. For example, the pressurizing member 40 can be installed in such a manner that the support arm 25 of the terminal 20 penetrates into the groove portion 42 of the pressurizing member 40 in a state where the pressurizing member 40 stands upward so as to be in the open position. Forty cam portions 43 are accommodated in the rotation support portion 25A of the terminal 20 (see FIG. 3A).

  (4) Next, as shown in FIG. 3C, the locking member 30 is inserted into the holding opening 16 of the housing 10 from the left side of the connector 1. The protrusion 31A of the arm portion 31 bites into the inner surface of the holding opening 16 and prevents the protrusion 31A from coming off. In this state, the lower surface 33 </ b> A of the contact surface portion 33 of the locking member 30 is located at substantially the same level as the lower surface of the housing 10. In the connector 1 assembled in this way, the pressing member 40 is supported by the upper edge of the arm portion 31 of the locking member 30 from below by the rotation support portion 25A of the terminal 20 from above.

<In use>
(1) First, as shown in FIGS. 3A to 3C, the pressure member 40 is brought to the open position. In this open position, the insertion slot 11 of the housing 10 is opened to the left between the support arm 25 and the contact arm 26 of the terminal 20.
(2) The flat conductor P is directed to the right as shown by a two-dot chain line in FIGS. 3A to 3C, and the insertion opening 11 between the support arm 25 and the contact arm 26 of the terminal 20 is inserted. insert. The flat conductor P is inserted without difficulty, and the tip of the flat conductor P comes into contact with the front regulating wall 13 in the housing 10 and stops at a predetermined insertion position. At the insertion position, the contact portion 26A of the terminal 20 is in light contact with a connection circuit portion (not shown) provided on the lower surface of the flat conductor P.

  (3) The pressure member 40 is rotated to the closed position shown in FIGS. 4 (A) to 4 (C). In the closed position, the pressing member 40 strongly presses the flat conductor P, thereby increasing the contact pressure between the contact portion 26A of the terminal 20 and the connecting circuit portion of the flat conductor P. Therefore, the connector 1 and the flat conductor The electrical connection with P is ensured. At the position of the locking member 30 in the terminal arrangement direction, the locking protrusion 32 of the locking member 30 enters the inside of the receiving space 44 of the pressure member 40. Thus, even when the pressing member 40 receives an external force in the lateral direction, that is, in the longitudinal direction of the flat conductor P, the inner wall surface forming the receiving space 44 of the pressing member 40 is the locking protrusion of the locking member 30. Since 32 is surrounded from four sides, the pressing member 40 does not come off due to contact with the inner wall surface.

  Further, since the locking member 30 is made of metal, sufficient strength is secured to prevent the pressing member 40 from coming off even if the locking protrusion 32 is small. Further, when the pressure member 40 is in the closed position, the locking protrusion 32 is positioned within the thickness range of the pressure member 40 in a direction perpendicular to the plane of the flat conductor. Therefore, it can be avoided that the connector 1 is enlarged in the same direction due to the provision of the locking projection 32. Further, in the present embodiment, since the receiving space 44 is formed as a concave portion in the pressure member 40, a decrease in the strength of the pressure member 40 due to a decrease in the thickness of the pressure member 40 can be minimized. Can do.

  In the above, the case where a flat conductor having a straight side edge as shown by a two-dot chain line in FIG. 1 (B) is connected to the connector 1 has been described. It is also possible to connect to a flat conductor having an edge part protruding sideways at the edge.

  FIG. 5 is a perspective view schematically showing the vicinity of the locking member 32 in the connector 1 to which a flat conductor having an ear portion is connected. As shown in FIG. 5, the flat conductor P ′ has an ear P′- 1 protruding partly on the side thereof. The ear portion P′-1 is in a curved portion 35 formed by the upper edge of the contact surface portion 33, the locking projection portion 32, and the restriction portion 34 in a state where the flat conductor P ′ is connected to the connector 1. To position. As a result, even if an external force in the direction of disconnecting from the connector 1 acts on the flat conductor P ′, the ear P′-1 contacts the restricting portion 34 and the movement of the flat conductor P ′ in the same direction is restricted. Therefore, the flat conductor P ′ is prevented from coming off.

  Further, when the pressurizing member 40 is in the closed position, as shown in FIG. 5, the left edge portion 44 </ b> A of the receiving cavity 44 enters the curved portion 35 formed in the locking member 30, and is flat. It is located opposite to the upper surface of the conductor P ′. As a result, the ear portion P′-1 of the flat conductor P ′ is also restricted from moving upward, so that the flat conductor P ′ can be more reliably prevented from coming off upward.

  A flat conductor, such as the flat conductor P ′, having ears formed on the side edges thereof is positioned by contact with the regulation wall 13 at the tip of the flat conductor when inserted into the connector 1. However, the positioning is also possible by bringing the ear portion into contact with the locking projection 32. In this case, by forming a large dimension in the height direction of the locking projection 32, it is possible to secure a wide range that can contact the ear P'-1, so that the flat conductor P 'can be easily inserted. it can.

  In the present embodiment, the locking member 30 is provided adjacent to the terminal at the end outside the terminal arrangement range, but the locking member 30 may also be provided within the terminal arrangement range. As a result, the locking protrusion 32 can be locked to the wall surface forming the receiving space 44 over the entire arrangement range, so that the pressing member 40 can be prevented from coming off more reliably.

<Second embodiment>
In this embodiment, in the closed position, the pressure member is penetrated in the direction in which the locking projection extends, and the receiving space is formed, so that the receiving space of the pressure member is formed as a recess. The configuration is different from the embodiment. FIG. 6 is a cross-sectional view of the connector according to the present embodiment. This figure is a cross-sectional view at the position of the locking member in the terminal arrangement direction, and shows a state where the pressure member is in the closed position. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 6, the receiving space 44 ′ of the pressure member 40 ′ is formed as a through-hole portion that penetrates in the vertical direction at the closed position. If there is no problem with the strength of the pressure member, the length in which the locking member 32 protrudes upward is further increased by forming the receiving space 44 'in this way, by the amount of penetration of the pressure member. Can be formed. As a result, the contact area between the wall surface forming the receiving space 44 ′ and the locking projection 32 can be increased. That is, since the locking amount of the locking protrusion 32 can be increased, the movement of the pressure member 40 'in the lateral direction is restricted, and the pressure member 40' is prevented from coming off more reliably.

  In the present embodiment, since the receiving space is formed as a through-hole, the inner wall surface has four closed wall surfaces. However, as a modification, it is sufficient to have three wall surfaces. May be open to one side. This is because if the three wall surfaces are provided, the strength of the pressure member at this portion is hardly reduced by forming the receiving space.
