Description

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

  In an electrical connector, an insulating film such as an oxide film is formed over time on the surface of a terminal or a flat conductor terminal (corresponding circuit part) connected to the terminal, or dust is formed between the terminal and the corresponding circuit part. There may be dust. The presence of the insulating coating or dust becomes a factor that causes problems in the electrical connection state. In order to avoid such a problem, when the electrical connectors are connected to each other or between the electrical connector and the flat conductor, the terminals that come into contact with each other with contact pressure are rubbed together to remove the insulating coating and dust, so-called wiping is performed. There is also a connector.

  An electrical connector disclosed in Patent Document 1 is known as an electrical connector for a flat conductor. The electrical connector is formed by arranging and holding a plurality of substantially U-shaped terminals in a connector main body (housing) in which a receiving space for receiving an FFC (flat conductor) and a slider described later is received from an opening. . A flexible upper arm portion of the terminal extends toward the opening at an upper position in the receiving space of the connector in a flexible state, and a contact portion (contact) protruding downward at the tip of the upper arm portion. Part) is formed.

  The electrical connector also has a separate slider that is used when connecting to the FFC. The slider is L-shaped, and a horizontal connection portion extending in the FFC insertion / removal direction is provided with a metal connection terminal extending continuously from the upper surface to the lower surface at a position corresponding to each terminal and covering the slider. A protrusion for connecting to the FFC terminal (corresponding circuit portion) is formed on the lower surface of the connection terminal.

  In the connection between the electrical connector and the FFC, first, the FFC is inserted into the receiving space of the connector main body and disposed on the lower surface of the receiving space. Here, the distance Y between the upper surface of the FFC and the contact portion of the terminal is smaller than the height dimension X of the horizontal portion of the slider. Next, the horizontal portion of the slider is inserted into the receiving space, specifically, between the FFC and the upper arm portion of the terminal. Since the dimension X is larger than the distance Y, the horizontal portion of the slider enters while increasing the distance between the upper arm portion and the FFC, that is, while elastically displacing the upper arm portion of the terminal upward. As a result, the contact portion of the upper arm portion comes into contact with the upper surface of the connection terminal of the slider with contact pressure, and the protrusion portion on the lower surface of the connection terminal comes into contact with the FFC terminal disposed on the upper surface of the FFC. The terminal and the FFC are electrically connected via a connection terminal.

  Further, in Patent Document 1, during the insertion of the horizontal portion of the slider into the receiving space, the contact portion of the terminal, the upper surface of the connection terminal of the slider, and the projection of the connection terminal and the FFC terminal are inserted into the horizontal portion. Rub in direction. As a result, the insulating film is removed, that is, so-called wiping, is performed on the contact portions, the FFC terminals, the upper surfaces of the connection terminals and the protrusions.

JP 2001-135379 A

  In the electrical connector disclosed in Patent Document 1, connection terminals corresponding to all the terminals are provided on the slider, and wiping is performed by rubbing the terminals and the connection terminals with contact pressure. Therefore, in proportion to the increase in the number of terminals, the resistance force to the slider due to friction generated during wiping increases. This means that the force required when inserting the slider is increased against the resistance force. As a matter of course, if the contact pressure between the terminal and the connection terminal is set to be low so as to reduce the resistance force within the range in which the wiping effect is not impaired, the reliability of contact between the terminal and the connection terminal is lowered. End up.

  It is preferable that the ease of insertion of the slider, the effect of wiping, and the reliability of contact between terminals can be adjusted according to the use environment. However, in the electrical connector described in Patent Document 1, since the correspondence relationship between the terminals, the connection terminals, and the FFC terminals is fixed, such adjustment is difficult.

  In view of such circumstances, the present invention can be adjusted so as to obtain the ease of insertion of a flat conductor, the effect of wiping, and the reliability of contact between terminals even when the number of terminals increases. It aims at providing the electrical connector for type | mold conductors.

  An electrical connector for a flat conductor according to the present invention is made by maintaining a flat surface of a metal plate, and extends in the insertion / extraction direction of the flat conductor to a corresponding circuit portion formed on one surface of the flat conductor. A plurality of terminal members having contact arm portions formed with contact portions to be contacted, a housing made of an electrically insulating material for arranging and holding the plurality of terminal members, and an open position and a flat type capable of inserting a flat conductor A pressurizing member that can rotate between a closed position that increases the contact pressure of the contact portion of the terminal member with respect to one surface of the conductor.

<First invention>
In such an electrical connector for a flat conductor, in the first invention of the present invention, some of the plurality of terminal members extend in the insertion / extraction direction on the other surface side of the flat conductor, and the pressure member is at least Indirect biasing that indirectly biases the other surface of the flat conductor toward the contact portion via the pressure member during insertion of the flat conductor by elastic contact with the pressure member in the open position Formed as an urging terminal member having an arm portion, and the terminal members other than the urging terminal member among the plurality of terminal members are flat conductors during rotation of the pressing member from the open position to the closed position. A gap allowing the regulated portion formed on the pressure member to move to a predetermined position in a direction away from the other surface is formed between the regulated portion and a predetermined amount or more of the regulated portion. Terminal member formed as a regulating terminal member having a regulating arm portion for regulating displacement It is characterized in that the containing.

  In the present invention, the indirect urging arm portion of the urging terminal member urges the flat conductor toward the contact portion of the terminal member, and the contact portion contacts the corresponding circuit portion of the flat conductor with contact pressure. Therefore, when the flat conductor is inserted into the electrical connector, the contact portion and the corresponding circuit portion rub against each other with sufficient contact pressure, and the insulating coating and dust formed on the two portions are removed, that is, wiping is performed. Is called.

  In a conventional electrical connector, the force (insertion force) required to insert the flat conductor can be reduced as the force (biasing force) that urges the flat conductor toward the contact portion of the terminal member is smaller. Therefore, the contact pressure between the terminal member of the electrical connector and the corresponding circuit portion of the flat conductor may be insufficient, and the reliability of electrical contact may be reduced. On the other hand, as the urging force increases, the reliability of electrical contact can be improved. However, the insertion force of the flat conductor increases correspondingly, and it becomes difficult to insert the flat conductor.

  In the present invention, some of the plurality of terminal members are provided as biasing terminal members, and the biasing force toward the contact portions of all the terminal members is covered by the biasing terminal members. That is, the magnitude of the biasing force is determined by the number of biasing terminal members. Specifically, the urging force increases as the number of urging terminal members increases, and decreases as the number decreases. Thus, since the magnitude of the urging force is adjusted by increasing or decreasing the number of urging terminal members, by increasing or decreasing the number of urging terminal members within a range that does not impair the wiping effect, It is possible to adjust so as to obtain the ease of insertion, the effect of wiping, and the reliability of contact between the terminal members.

  Further, when the distance between the pressing member and the contact portion of the terminal member is smaller than the thickness of the flat conductor, the flat conductor is inserted between the pressing member and the contact portion of the terminal member. Then, the flat conductor urges the pressure member in a direction away from the other surface of the flat conductor (hereinafter referred to as “separation direction”). Therefore, the pressure member urges the indirect urging arm portion in elastic contact with the pressure member in the separation direction. In the present invention, the gap that allows the regulated portion to be displaced to a predetermined position is formed between the regulating arm portion of the regulating terminal member and the regulated portion of the pressure member. The indirect biasing arm portion biased in the separating direction is easily elastically displaced within a predetermined range. When the regulated portion reaches a predetermined position, the regulated arm portion restricts the displacement of the regulated portion in the separating direction, and thus the displacement of the pressure member by a predetermined amount or more. As a result, the pressure member is stably supported.

  In the first invention, at least a part of at least one of the energizing terminal member and the restricting terminal member extends in the insertion / extraction direction of the flat conductor and elastically contacts the other surface of the flat conductor. It further has a direct urging arm portion that urges the flat conductor directly toward the contact portion, and at least some of the terminal members of the restriction terminal member are urged in the insertion / extraction direction. It is arranged at a position different from the contact part of the terminal member, and the remaining terminal member is arranged at the same position as the contact part of the biasing terminal member in the insertion / extraction direction, and the indirect biasing arm part is The biasing member is biased toward the contact portion of the regulating terminal member at a position different from the contact portion of the biasing terminal member in the insertion / extraction direction, and the direct biasing arm portion of the biasing terminal member is The contact part and the contact of the regulating terminal member located at the same position in the insertion / extraction direction with the contact part It may be biases the flat conductive towards parts.

  Thus, in addition to providing the indirect urging arm portion on the urging terminal member, the direct urging arm portion directly urging the flat conductor is made to be at least one of the urging terminal and the regulating terminal member. By providing at least some of the terminal members, the corresponding circuit portion of the flat conductor can be more reliably brought into contact with the contact portion of the biasing terminal member and the contact portion of the regulating terminal member with contact pressure. As a result, the wiping effect can be ensured satisfactorily.

<Second invention>
In such an electrical connector for a flat conductor, in the second invention of the present invention, the pressing member extends in the insertion / extraction direction on the other surface side of the flat conductor, and the pressing member elastically contacts the pressing member at least in the open position. An urging bracket member having an indirect urging arm portion for indirectly urging the other surface of the flat conductor through the pressure member during insertion of the flat conductor is provided, and among the plurality of terminal members In some terminal members, the regulated portion formed on the pressure member is displaced to a predetermined position in a direction away from the other surface of the flat conductor during rotation of the pressure member from the open position to the closed position. It is characterized in that it is formed as a regulating terminal member having a regulating arm portion that regulates a displacement of a prescribed amount or more of the regulated portion by forming a gap that permits this between the regulated portion.

  In the second invention, a biasing metal member having an indirect biasing arm portion is provided as a separate member from the terminal member, and the biasing force to the flat conductor is adjusted by increasing or decreasing the number of the biasing metal members. . Therefore, by increasing or decreasing the number of the urging metal members within a range where the wiping effect is not impaired, the ease of inserting the flat conductor, the wiping effect, and the reliability of contact between the terminal members are obtained. It becomes possible to adjust. The urging metal member can be made in a form that maintains the flat surface of the metal plate in the same manner as the terminal member.

  Further, similarly to the first invention, since the movement of the regulated portion of the pressure member by a predetermined amount or more is regulated by the regulation arm portion of the regulation terminal member, the pressure member is stably supported.

  In the second invention, at least a part of at least one member of the biasing metal member and the regulating terminal member extends in the insertion / extraction direction of the flat conductor and elastically contacts the other surface of the flat conductor to form a flat type. It further has a direct urging arm portion that urges the conductor directly toward the contact portion, and at least a part of the terminal members of the regulating terminal member has an urging bracket member in which the contact portion is in the insertion / extraction direction. The remaining terminal member is arranged at the same position as the contact portion of the urging metal member in the insertion / extraction direction, and the indirect energizing arm portion is The flat conductor is urged toward the contact portion of the regulating terminal member at a position different from the contact portion of the urging metal member in the insertion / extraction direction, and the direct urging arm portion is a contact portion of the urging metal member. And the contact portion of the regulation terminal member that is in the same position as the contact portion in the insertion / extraction direction It may be biases the flat conductive towards.

  Thus, by providing the direct biasing arm portion that biases the flat conductor directly on at least a part of at least one of the biasing metal member and the regulating terminal member, the contact portion of the terminal member In addition, the corresponding circuit portion of the flat conductor can be more reliably brought into contact with the contact pressure.

  In the present invention, a metal member that is a member different from the terminal member is provided, and the indirect biasing arm portion is provided on at least some of the plurality of terminal members and at least some of the plurality of metal members. It is provided. The urging force to the flat conductor is adjusted by increasing or decreasing the number of at least one of the terminal member having the indirect urging arm portion and the metal member having the indirect urging arm portion. Therefore, the flat conductor can be easily inserted by increasing or decreasing the number of at least one of the terminal member having the indirect urging arm portion and the metal member having the indirect urging arm portion as long as the wiping effect is not impaired. Now, it is possible to adjust so as to obtain the wiping effect and the reliability of contact between the terminal members.

There is a risk that the material may bend and break without being able to withstand the resistance, and wear may increase. Accordingly, the first to third inventions of the present invention provide a flat type as described above by adjusting the magnitude of the urging force and hence the insertion force of the flat conductor by increasing or decreasing the number of urging terminal members.

And a connecting portion 64 extending in a crank shape out of the housing from the lower part to the right.

  The locking arm portion 61 has a locking projection 61A that protrudes upward at the left end. The locking protrusion 61 </ b> A is located to the left of the left end of the indirect biasing arm 62 and protrudes into the receiving portion 12. The locked portion of the flat conductor P inserted into the receiving portion 12 and the locking protrusion 61A are locked in the flat conductor insertion / removal direction (left-right direction in FIG. 3). Omission is prevented. In this embodiment, as can be seen in FIG. 3, the locking protrusion 61A is located on the left side of the pressing member 50 in the open position, and the flat conductor P is inserted in the proper position. This can be easily confirmed visually.

  The indirect urging arm portion 62 has substantially the same shape as the indirect urging arm portion 42 of the urging terminal 40. The left end of the indirect biasing arm portion 62 is in the same position as the left end of the indirect biasing arm portion arm 42 in the left-right direction. The indirect urging arm portion 62 is similar to the indirect urging arm portion 42 in that the contact arm portion 21 and the restriction arm portion 22 of the first restriction terminal 20, the restriction arm portion 33 and the contact arm portion of the second restriction terminal 30. 34, the rigidity is lower than the contact arm portion 41 of the urging terminal 40, and it is easy to bend.

  Since the connection part 63 and the connection part 64 have the same shape as the connection part 23 and the connection part 24 of the 1st control arm part 20, the description is abbreviate | omitted. The urging bracket 60 is press-fitted into the holding groove 11 from the right side of the housing 10 and attached to the housing 10.

  As is often seen in FIG. 1, the pressure member 50 is provided so as to extend outward from the pressure member rotation space 13 of the housing 10, and the terminals 20, 30, 40 in the terminal arrangement direction. And it has the width | variety over the arrangement | sequence range of the urging | biasing metal fitting 60 mentioned later. The pressurizing member 50 has an open position in a vertically extending position as shown in FIGS. 2A, 2B, and 2C and FIGS. 8A, 8B, and 8C. It is possible to rotate between a closed position in a posture extending in the left-right direction as shown in FIG. The pressurizing member 50 enables the flat conductor P to be inserted into the receiving portion 12 in the open position, and presses the flat conductor P in the closed position to thereby connect the flat conductor P and the terminals 20, 30, 40. The contact pressure with the contact portions 21A, 34A, 41A is increased.

  2A, 2B, and 2C, the lower surface of the pressing member 50 in the open position and the contact arm portions 21A, 34A, and 41A of the terminals 20, 30, and 40, respectively. The dimension in the vertical direction of the gap formed between the two is narrower than the thickness dimension of the flat conductor P.

  The pressure member 50 is a slit-like groove portion at a position corresponding to the terminals 20, 30, 40 and the urging metal 60 in the terminal arrangement direction in a portion located in the pressure member rotation space 13 of the housing 10. 51, 52, 53, 54 are formed. As shown in FIGS. 2 (A), (B), (C), and FIG. 3, the groove 51 is inserted into the shaft restricting portion 22A of the first restricting terminal 20, and the groove 52 is the shaft restricting portion 33A. The groove 53 allows the left end of the indirect biasing arm 43 and the left end of the direct biasing arm 42 to enter, and the groove 54 allows the indirect biasing arm 62 to enter.

  As shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C, the groove portions 51, 52, and 53 are each formed with a shaft portion 55 </ b> A near the lower end portion of the pressure member 50. Further, as shown in FIG. 3, the groove portion 54 is formed at a position near the lower end portion of the pressure member 50 and a shaft portion 55B coaxial with the shaft portion 55A. The shaft portions 55 </ b> A and 55 </ b> B serve as the rotation center of the pressure member 50. As is often seen in FIGS. 2A, 2B, and 2C, the shaft portion 55A has a circular cross-sectional shape. On the other hand, the shaft portion 55B has a shape having a cam portion. Specifically, as shown in FIG. 3, the shaft portion 55B has a shape in which the upper half of the cross-sectional shape is a quadrangle and the lower half is a semicircle. That is, the upper surface of the shaft portion 55B forms a flat surface and forms a cam portion.

  In the present embodiment, when the pressing member 50 is in the open position, as shown in FIG. 3, the indirect urging arm portion 62 of the urging metal fitting 60 is a shaft at the straight lower edge portion at the left end. The pressing member 50 is supported in the open position in a state of elastically contacting the upper surface of the portion 55B and urging the pressing member 50 downward. Since the contact between the shaft portion 55B and the indirect biasing arm portion 62 is made over the entire upper surface of the shaft portion 55 in the left-right direction in FIG. 3, it is compared with a case where the cross-sectional shape of the shaft portion is circular. The contact area, in other words, the support area is large. Therefore, the shaft portion 55B at the position of the urging bracket 60 is formed in the shape of a cam portion having a flat surface as in this embodiment, so that the support state of the pressure member 50 in the open position is further stabilized. Can do.

  Immediately after the pressing member 50 is in the open position and the insertion of the flat conductor P is started, at the position of the first restriction terminals 20 in the terminal arrangement direction, as shown in FIG. It is supported from below by the lower finger portion 22A-2 of the restriction terminal 20, and a gap is formed between the shaft portion 55A and the upper finger portion 22A-1 of the first restriction terminal 20.

  Further, at the position of the second restriction terminal 30 in the terminal arrangement direction, as shown in FIG. 2 (B), the shaft portion 55A has the leg portion 33A-1 and the leg portion 33B of the restriction arm portion 33 of the second restriction terminal 30. -2 is restricted by the legs 33A-1 and 33A-2 in the left-right direction, and the shaft 55A and the groove bottom of the shaft restricting portion 33A in the second restricting terminal 30 A gap is formed in the vertical direction. In this embodiment, when the shaft portion 55A is viewed in the terminal arrangement direction, the shaft portion 55A is formed by the upper finger portion 22A-1, the lower finger portion 22A-2, the leg portion 33A-1, and the leg portion 33B-2. The shaft portion 55A is prevented from being detached from the terminals 20, 30, and 40.

  Further, at the position of the urging terminal 40 in the terminal arrangement direction, as shown in FIG. 2C, the shaft portion 55A of the pressing member 50 is directly in contact with the left end of the indirect urging arm portion 42 in the vertical direction. It is located between the left end of the urging arm 43. The indirect biasing arm portion 42 is in elastic contact with the shaft portion 55A of the pressing member 50 from above at the lower edge of the left end. A gap is formed between the shaft portion 55A and the left end of the direct biasing arm portion 43 in the vertical direction.

  A portion of the pressure member 50 located outside the pressure member rotation space 13 of the housing 10 is formed as an operation portion 56 for the operator to rotate the pressure member 50 with a finger or the like.

  2A, 2B, 2C and FIG. 3, the corner of the lower left corner of the wall forming the grooves 51, 52, 53 in a state where the pressure member 50 is in the open position. As will be described later, 57 functions as a portion that presses the flat conductor P downward during the rotation of the pressure member 50. Further, the side surface on the left side of the pressing member 50 is formed as a pressing surface 58 that presses the flat conductor P downward on the entire surface in the closed position (see FIG. 8). The distance from the center of the shaft portions 55A and 55B to the corner portion 57 is larger than the distance from the center of the shaft portions 55A and 55B to the pressing surface 58. Therefore, the pressing force against the flat conductor P by the corner 57 during the rotation of the pressing member 50 is larger than the pressing force against the flat conductor P by the pressing surface 58 in the closed position. Further, on the left part of the lower surface of the pressure member in a state where the pressure member 50 is in the open position, a slope 59 that is inclined downward from the corner portion 57 toward the right is formed. The inclined surface 59 is configured to be pressed toward the contact portions 21A, 34A, 41A while guiding the inserted flat conductor P.

  Hereinafter, the usage point of the connector 1 which concerns on this embodiment is demonstrated.

  First, the insertion of the flat conductor P into the connector 1 will be described with reference to FIGS. 2, 4, 5 and 6. From the start of insertion of the flat conductor P to completion, the pressing member 50 is in the open position as shown in FIGS. 2, 4, 5 and 6. Immediately after the insertion of the flat conductor P into the connector 1 is started, the flat conductor P is connected to any of the terminals 20, 30, 40 as shown in FIGS. 2 (A), (B), (C). There is no contact.

  When the flat conductor P is inserted from the left toward the receiving portion 12 of the connector 1, the tip of the flat conductor P (the right end in FIGS. 2A, 2 </ b> B, and 2 </ b> C) is the housing 10. The guide slope 15 advances toward the space between the lower surface of the pressure member 50 and the contact portion 34 </ b> A of the second restriction terminal 30.

  When the insertion of the flat conductor P further proceeds, the flat conductor P comes into contact with the inclined surface 59 on the lower surface of the pressure member 50 as shown in FIGS. 4 (A), (B), and (C). It enters between part 34A. As described above, the distance between the lower surface of the pressing member 50 and the contact portion 34A is smaller than the thickness dimension of the flat conductor P. Accordingly, the flat conductor P enters the space between the lower surface of the pressure member 50 and the contact portion 34A by expanding. Specifically, as can be understood by comparing the positions of the shaft portions 55A in FIGS. 2 (A), 2 (B) and FIGS. 4 (A), 4 (B), the entered flat conductor P is the flat conductor P. The pressurizing member 50 is pushed upward on the upper surface.

  In the present embodiment, a gap is formed in the vertical direction between the shaft portion 55A of the pressing member 50 and the upper finger portion 22A-1 of the shaft restricting portion 22 of the first restricting terminal 20, and the shaft portion 55A and the first A gap is also formed in the vertical direction between the second restriction terminal 30 and the shaft restriction portion 33A. In addition, the indirect urging arm portion 42 of the urging terminal 40 and the indirect urging arm portion 62 of the urging metal fitting 60 that are in contact with the shaft portions 55A and 55B from above are more rigid than the contact arm portion 34 of the second regulating terminal 30. Is easy to bend. Therefore, the pressing member 50 easily moves upward while elastically displacing the indirect arm portions 42 and 62 at the shaft portions 55A and 55B. As a result of the upward movement of the pressure member 50, the lower surface of the pressure member 50 is more than the urging protrusion 43A of the direct urging arm portion 42 of the urging terminal 40, as is often seen in FIG. Brought up.

  The elastically displaced indirect urging arm portions 42 and 62 generate a downward reaction force, and urge the shaft portions 55A and 55B and the pressing member 50 downward. As a result, the urging arm portions 42 and 62 indirectly urge the upper surface of the flat conductor P toward the contact portion 34 </ b> A via the pressure member 50. The corresponding circuit portion formed on the lower surface of the flat conductor P that receives the indirect biasing force from the biasing arm portions 42 and 62 contacts the contact portion 34A with a contact pressure sufficient for wiping. In the present embodiment, the contact portion 34A is hardly elastically displaced downward even in the corresponding circuit portion, and the top portion of the contact portion 34A is located slightly above the top portions of the contact portions 21A and 41A. Maintained.

  When the flat conductor P is further inserted while the contact state between the corresponding circuit portion of the flat conductor P and the contact portion 34A is maintained, the corresponding circuit portion of the flat conductor P and the contact portion 34A are sufficient. Rubbing with a good contact pressure, wiping, that is, the removal of the insulating film and dust formed on the corresponding circuit portion and the contact portion 34A is performed satisfactorily.

  When the insertion of the flat conductor P further proceeds, the flat conductor P is formed on the lower surface of the pressure member 50 at the position of the first restriction terminal 20 in the terminal arrangement direction, as can be seen in FIG. As shown in FIG. 5 (C), the urging protrusion 43A of the urging arm 43 and the contact part 41A directly at the position of the urging terminal 40 in the terminal arrangement direction. Enter between.

  In the present embodiment, as described above, the right end portion of the flat conductor P as shown in FIGS. 4A, 4 </ b> B, and 4 </ b> C is the position of the contact portion 34 </ b> A of the second restriction terminal 30. The top portions of the contact portions 21A and 41A are located slightly below the top portion of the contact portion 34A in contact with the corresponding circuit portion of the flat conductor P. Therefore, the indirect urging force by the indirect urging arm portions 42 and 62 does not bring the lower surface of the flat conductor P into contact with the contact portions 21A and 41A. As will be described later, the lower surface of the flat conductor P and the contact portions 21A and 41A are brought into contact with each other by the urging force directly from the urging arm portion 43.

  As described above, in the biasing terminal 40, the distance between the biasing protrusion 43A of the direct biasing arm 43 and the contact portion 41A of the contact arm 41 is smaller than the thickness dimension of the flat conductor P. . Further, since the direct biasing arm portion 43 has lower rigidity than the contact arm portions 21 and 41, as shown in FIG. 5C, a flat conductor is provided between the biasing projection portion 43A and the contact portion 41A. When P enters, the urging protrusion 43A is pushed up by the upper surface of the flat conductor P, and the urging arm 43 is directly elastically displaced. The elastically displaced direct urging arm portion 43 generates a reaction force to urge the upper surface of the flat conductor P directly downward. As a result, the corresponding circuit portion formed on the lower surface of the flat conductor P comes into contact with the contact portion 21A of the first restriction terminal 20 and the contact portion 41A of the biasing terminal 40 with contact pressure.

  Therefore, when the flat conductor P is further inserted while maintaining this contact state, the corresponding circuit portion of the flat conductor P and the contact portion 21A and the contact portion 41A rub against each other with sufficient contact pressure, so that wiping is good. Done.

  When the insertion of the flat conductor P further proceeds, as shown in FIGS. 6A, 6B, and 6C, the right end portion of the flat conductor P comes into contact with the rear wall portion 12A of the receiving portion 12. The insertion of the flat conductor P is completed. In the present embodiment, as described above, the flat conductor P is formed with an ear-shaped locked portion that protrudes in the width direction of the flat conductor P. During the insertion of the mold conductor P, the latching protrusion 61A of the urging metal fitting 60 is overcome, and when the insertion of the flat conductor P is completed, it is positioned to the right of the locking protrusion 61A. That is, the locking protrusion 61A and the locked portion are brought into a positional relationship in which the end portions face each other in the direction in which the flat conductor P is pulled out. Therefore, even if the flat conductor P moves in the extraction direction, the locking protrusion 61A and the locked portion are locked in the extraction direction, so that the flat conductor P can be prevented from coming off well. Is done.

  In the present embodiment, the upper finger portion 22A-1 of the shaft restricting portion 22 of the first restricting terminal 20 and the shaft restricting portion 33A of the second restricting terminal 30 restrict the displacement of the shaft portion 55A by a predetermined amount or more. As a result, excessive displacement of the pressure member 50 over a predetermined amount is restricted, and the pressure member 50 can be stably supported.

  Next, the rotation operation of the movable member 50 from the open position to the closed position will be described with reference to FIGS. First, when the insertion of the flat conductor P as shown in FIGS. 6A, 6B, and 6C is completed, the pressing member 50 in the open position is directed toward the closed position, that is, The operation portion 56 of the pressure member 50 is operated so that the pressure member 50 rotates counterclockwise around the shaft portion 55A.

  The pressure member 50 rotated toward the closed position presses the upper surface of the flat conductor P at the corner 57 during the rotation, as is often seen in FIGS. 7 (A), (B), and (C). To do. As a result, the contact arm portion 21 of the first restriction terminal 20, the contact arm portion 34 of the second restriction terminal 30, and the contact arm portion 41 of the urging terminal 40 are pressed against the lower surface of the flat conductor P and the maximum displacement amount is obtained. Is elastically displaced downward.

  When the pressing member 50 is further rotated, the contact arm portions 21, 34, 41 are released from the pressing by the corner portion 57, and slightly return upward so as to reduce the amount of elastic displacement. When the pressing member 50 reaches the closed position, the pressing surface 58 of the pressing member 50 is brought into contact with the upper surface of the flat conductor P as shown in FIGS. 8 (A), (B), and (C). Contact is made with contact pressure, and the rotation operation of the pressure member 50 is completed. In the closed position, the contact arm portions 21, 34, and 41 are pushed down by the lower surface of the flat conductor P and elastically displaced, and the reaction force from the contact arm portions 21, 34, and 41 is regulated by the restricting arm portions 22 and 33. The contact portions 21A, 34A, 41A of the contact arm portions 21, 34, 41 are in contact with corresponding circuit portions formed on the lower surface of the flat conductor P, respectively. As a result, the electrical contact state between the contact portions 21A, 34A, 41A and the corresponding circuit portion of the flat conductor P is maintained with sufficient contact pressure.

  In the present embodiment, the pressure member 50 is in the open position, that is, when the flat conductor P is inserted, the indirect urging arm portion 42 of the urging terminal 40, the direct urging arm portion 43, and the indirect urging of the urging bracket. An urging force is applied to the flat conductor P by the arm portion 62. Therefore, if a part of the plurality of first regulating terminals 20 provided in the connector 1 is replaced with the urging terminals 40 and the number of the urging terminals 40 is increased, the urging force also increases. When a part of the plurality of urging terminals 40 is replaced with the first restriction terminal 20 and the number of the urging terminals 40 is reduced, the urging force is also reduced. That is, according to this embodiment, the magnitude of the urging force can be adjusted by increasing or decreasing the number of the urging terminals 40. Therefore, according to the design conditions for the terminals, the number of the urging terminals 40 is appropriately increased or decreased within a range that does not impair the wiping effect, thereby facilitating the insertion of the flat conductor P, the wiping effect, and the flat type. It is possible to adjust so as to obtain reliability of contact between the corresponding circuit portion of the conductor P and the contact portions 21A, 34A, 41A of the terminals 20, 30, 40. Further, in order to reduce the urging force, a part of the urging terminal 40 is not replaced with a part of the urging terminal 40 without replacing a part of the urging terminal 40 with the indirect urging arm portion 42, The urging arm 43 may be directly removed.

  Further, in the present embodiment, the shaft restriction portions 22A and 33A that form gaps between the shaft portion 55A and the shaft portion 55A that allow the shaft portion 55A of the pressure member 50 to be displaced upward to a predetermined position are provided as the restriction terminals 20 and 33A. 30. Therefore, while the indirect urging arm portion 42 of the urging terminal 40 and the indirect urging arm portion 62 of the urging metal fitting 60 are pushed by the pressing member 50 and are easily elastically displaced within a predetermined range, By restricting the shaft portions 55A and 55B and excessive displacement of the pressure member 50 by a predetermined amount or more, the pressure member 50 can be supported stably. Further, since the shaft restricting portions 22A and 22B support the reaction force that the pressure member 50 receives from the contact arm portions 21, 34, and 41 through the flat conductor P in the closed position, the flat conductor is in the closed position. The contact pressure between the corresponding circuit portion of P and the contact portions 21A, 34, 41A of the contact arm portions 21, 34, 41 is favorably maintained.

  In the present embodiment, the urging metal fitting is provided in the connector, but the urging metal fitting is not an essential member and may not be provided in the connector. In this embodiment, the flat conductor P is urged downward by the urging terminal and the urging metal fitting. However, all the urging terminals are replaced with the first urging terminals, and only the urging metal fittings are used. The flat conductor P may be energized by the above. In this case, the urging arm portion is directly provided on at least one of the first restriction terminal, the second restriction terminal, and the urging metal fitting.

  In the present embodiment, the shaft portion of the pressure member has a circular cross-sectional shape at the position of the terminal in the terminal arrangement direction. Instead, the shaft portion has a shape having a cam portion. Also good.

  In the present embodiment, the contact portion of the second restriction terminal is located closer to the opening side of the receiving portion in the connector insertion / removal direction than the contact portion of the first restriction terminal and the contact portion of the biasing terminal. For example, the contact portion of the first restriction terminal and the contact portion of the biasing terminal may be located closer to the opening side of the receiving portion than the contact portion of the second restriction terminal. In this case, it is preferable that the respective top portions of the contact portion of the first restriction terminal and the contact portion of the biasing terminal are located above the top portion of the contact portion of the second restriction terminal. Moreover, each contact part of a 1st control terminal, a 2nd control terminal, and an energizing terminal may exist in the same position in a connector insertion / extraction direction.

<Second embodiment>
In the present embodiment, the biasing terminal does not have a direct biasing arm portion, and the lower surface of the pressure member in the open position is formed as a slope that slopes downward as it goes forward in the insertion direction of the flat conductor. The biasing terminal has a biasing arm portion directly and is different from the first embodiment in which the right portion of the lower surface of the pressure member is formed as a substantially flat surface in the insertion / extraction direction. . Since the connector according to this embodiment has the same basic configuration as the connector according to the first embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The description will focus on the differences from the form.

  FIG. 9 is a vertical cross-sectional view immediately after the flat conductor insertion of the connector 1 ′ according to the present embodiment, (A) is a cross section at the position of the first restriction terminal 20, and (B) is the second restriction terminal 30. (C) shows a cross section at the position of the urging terminal 40 ′. As shown in FIG. 9C, the urging terminal 40 'according to the present embodiment has a shape in which the urging terminal 43 is omitted directly from the urging terminal 40 in the first embodiment. Further, as shown in FIGS. 9A, 9B, and 9C, the pressure member 50 ′ in the open position is formed as a large inclined surface that inclines downward as the lower surface goes rightward. ing.

  In the present embodiment, when the flat conductor P is inserted into the receiving portion 12 of the connector 1 ′ from the left, first, as in the first embodiment, the configuration shown in FIGS. 10A, 10B, and 10C is better. As can be seen, the flat conductor P enters between the pressure member 50 ′ and the contact portion 34 </ b> A of the second regulating terminal 30. The pressure member 50 ′ is pushed up by the flat conductor P, and the indirect biasing arm portion 42 ′ is elastically displaced upward and generates a reaction force, that is, a biasing force downward. Then, as a result of the flat conductor P receiving an indirect urging force from the indirect urging arm portion 42 ′ via the pressure member 50 ′, the corresponding circuit portion on the lower surface of the flat conductor P and the second regulating terminal 30. Wiping with the contact portion 34A is performed.

  As described above, in the present embodiment, the pressing member 50 ′ in the open position is formed as a large inclined surface that is inclined downward as the lower surface goes rightward. The inclined surface contacts the contact portion 41 ′ of the biasing terminal 40 ′ when the flat conductor P enters between the pressure member 50 ′ and the contact portion 34A and the pressure member 50 ′ is pushed upward. A and the contact portion 21A of the first regulating terminal 20 and the lower surface of the pressure member 50 ′ are formed with an inclination and size such that the distance in the vertical direction is smaller than the thickness dimension of the flat conductor P. ing.

  When the flat conductor P is further inserted, the flat conductor P moves to the right from the position indicated by the solid line in FIGS. 10A, 10B, and 10C, and the pressure member 50 It enters between the lower surface of 'and the contact portions 21A, 41'A. As described above, since the distance between the lower surface of the pressure member 50 ′ and the 21A, 41′A is smaller than the thickness dimension of the flat conductor P, the pressure member 50 ′ is further separated by the flat conductor P. It is pushed up and moves upward. At this time, the indirect urging arm portion 42 ′ of the urging terminal 40 ′ is pushed by the shaft portion 55 ′ of the pressing member 50 ′ and elastically displaced upward. The upward movement of the pressure member 50 ′ is caused by the gap between the shaft portion 55 ′ A and the upper finger portion 22 A- 1 of the first restriction terminal 20, the shaft restriction portion 33 A between the shaft portion 55 ′ A and the second restriction terminal 30. Is allowed within a predetermined range by the gap between the two. The shaft portion 55'A is urged downward by the reaction force from the indirect urging arm portion 42 ', and the flat conductor P is urged downward via the pressure member 50'. As a result, the corresponding circuit portion formed on the lower surface of the flat conductor P comes into contact with the contact portions 21A and 41'A with contact pressure.

  Therefore, when the flat conductor P is further inserted while maintaining this contact state, the corresponding circuit portion of the flat conductor P and the contact portions 21A, 41′A rub against each other with sufficient contact pressure, and the wiping is good. Done. When the flat conductor P is further inserted, the right end portion of the flat conductor P is located at the back of the receiving portion 12 as shown by a two-dot chain line in FIGS. 10 (A), (B), and (C). The flat conductor P is completely inserted by contacting the wall portion 12A. It is also possible to reduce the inclination angle of the lower surface of the pressure member shown in FIGS. 10A, 10B, and 10C and position the contact portions 21A, 41′A above the contact portion 34A. The same wiping effect as in the present embodiment can be obtained.

  Also in the present embodiment, as in the first embodiment, by increasing or decreasing the number of biasing terminals 40 ′, the ease of insertion of the flat conductor P, the effect of wiping, and the corresponding circuit portion and terminals of the flat conductor P It is possible to adjust so as to obtain the reliability of contact with the contact portions 21A, 34A, 41′A of 20, 30, 40 ′. Further, according to the present embodiment, as in the first embodiment, the pressing member 50 is controlled by restricting excessive displacement of the pressing member 50 by a predetermined amount by the shaft restricting portions 22A and 33A of the restricting terminals 20 and 30. 50 stable supports are possible.
