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.

  The reinforcing sheet is adhered to the surface of the flat conductor opposite to the surface of the connecting portion at the tip portion to be connected to the connector. In order to enhance the effect of preventing pull-out from the connector after connection with the connector, the flat conductor is provided with a locking step, for example, an ear or a notch recess, on both side edges of the reinforcing sheet. It is intended to be engaged with the part. On the other hand, the connector is formed with a protrusion on the bottom wall portion or the inlet wall portion of the housing where the connecting portion of the flat conductor is inserted, and the protrusion engages with the locking step portion of the flat conductor. And there is a type that prevents omission. However, when the flat conductor is inserted into the bottom wall projection, the tip of the flat conductor gets caught, and the projection on the inlet wall is at the entrance position. Must be inserted. In either case, it is difficult to insert a flat conductor.

On the other hand, Patent Document 1 discloses a connector in which a member that engages with the latching step portion of the flat conductor is provided on the relatively inner side of the housing. In this Patent Document 1, a locking member provided integrally with the housing as a part of the housing, or a locking member as a metal fitting attached to the housing as another embodiment of this Patent Document 1 is shown. . Each of the locking members has an arm shape extending forward from the back of the housing in the longitudinal direction of the flat conductor, and has a protrusion at the tip thereof. The arm-shaped locking member can be elastically deformed, and when the flat conductor is inserted, the protrusion comes into contact with the tip of the flat conductor and the locking member is elastically deformed to be deformed at a predetermined position of the flat conductor. Until the insertion is completed, the protrusion is locked in a notch recess as a locking step portion of the flat conductor, and the elastic deformation is released. Thus, the flat conductor is prevented from coming off by the locking between the protrusion and the locking step.
JP 2004-165046 A

  However, the connector disclosed in Patent Document 1 has room for improvement in that an insertion force is required when a flat conductor is inserted and that a locking force is not so large.

  First, regarding the insertion force, the fact that the flat conductor is brought into contact with the protrusion of the locking member at the time of insertion to allow the locking member to bend elastically is necessary to cause the elastic bending. It requires an insertion force.

  Next, the protrusion of the locking member is locked with the locking step portion of the flat conductor using the elastic displacement amount as the locking amount. Therefore, the amount of locking cannot be increased too much. Further, if the flat conductor is pulled strongly in the pulling direction, since there is no means for preventing the elastic displacement of the locking member after locking with the flat conductor, a deflection corresponding to the elastic displacement amount occurs, The flat conductor may come off, and it cannot be said that the locking force is sufficient.

  In view of such circumstances, it is an object of the present invention to provide an electrical connector for a flat conductor that can be easily inserted into a connector of a flat conductor and that can secure a sufficient locking force for preventing disconnection. To do.

  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 connecting portion adjacent to a base portion on which a mounted portion for attachment is provided, the support arm and the contact arm extending in a state of being spaced apart from each other; The tip of the flat conductor inserted from the outside of the housing at an interval can be received, and the pressurization that can rotate between the open position that facilitates the reception of the flat conductor and the closed position that presses the flat conductor The member is supported by the rotation support portion of the support arm, and the pressurizing member increases the contact pressure between the flat conductor and the contact portion of the contact arm by rotating to the closed position. A locking member that locks with the locked portion of the flat conductor to prevent the flat conductor from coming off It is attached to the housing.

  In such an electrical connector for a flat conductor, in the present invention, the locking member is made of a metal plate, and the plate surface is parallel to the terminal and is attached to the housing, and the locking member supports the terminal. A pressure receiving arm and a locking arm extending from the connecting portion are provided at positions corresponding to the arm and the contact arm, respectively, and the pressure receiving arm is moved from the cam portion of the pressure member when the pressure member is rotated to the closed position. The pressure receiving arm receives a force, and the pressure receiving arm is displaced in a direction away from the flat conductor by receiving the force at the pressure receiving portion, and the locking arm has a locking projection facing the flat conductor. Then, the displacement of the pressure receiving arm receives a force through the connecting portion and the locking arm is displaced to lock the locking protrusion with the locked portion of the flat conductor. .

  In the electrical connector for flat conductors of the present invention having such a configuration, first, the pressure member is brought to the open position, and in this state, the distal end portion of the flat conductor is inserted into the housing from the opening of the housing. . This tip portion is easily inserted without receiving resistance by the locking projection of the locking member. After that, when the rotating member is brought to the closed position, the flat conductor is pressed against the contact portion of the contact arm of the terminal to make an electrical connection, and the pressure receiving arm of the locking member is also connected from the pressurizing member. Receiving force, rotational deflection occurs with the connecting portion as a fulcrum. As a result, the locking projection of the locking arm extending from the connecting portion is displaced and locked with the locked portion of the flat conductor. This locking is maintained as long as the pressure member is in the closed position.

  In the present invention, the terminal and the locking member are formed in the same shape, the terminal supporting arm and the pressure receiving arm of the locking member correspond to each other, and the terminal contact arm and the locking member locking arm correspond to each other. Can be like that. By making the terminal and the locking member the same shape, the terminal and the locking member can be made without distinction, the number of types of parts is reduced, and the manufacturing cost and the management cost are reduced.

  According to the present invention, the locking protrusion of the locking member can be formed so as to protrude from the contact portion of the terminal toward the flat conductor in a free state before displacement. As a result, the locking amount of the locking protrusion with respect to the flat conductor increases, and the locking force increases.

  The increase of the locking force can be realized by changing the shape of the pressure member without changing the locking member to the terminal. For example, the pressurizing member is set so that the pressurizing amount to the flat conductor at the position corresponding to the locking member in the arrangement direction of the terminals is larger than the pressurizing amount at the corresponding position to the terminal. By doing so, due to an increase in the reaction force from the flat conductor, the locking protrusion of the locking member is greatly displaced, and the locking force is increased. Moreover, the terminal and the locking member may have the same shape. The increase in the amount of pressurization is, for example, that the flat conductor is strongly pressed by the cam portion of the pressurizing member and receives a reaction force from the flat conductor, so that the cam portion displaces the locking arm greatly, or is added. The cam portion can greatly displace the locking arm upon receiving a reaction force from the flat conductor by strongly pressing the flat conductor with the operating portion of the pressure member.

  As described above, according to the present invention, when the pressurizing member is rotated to the closed position that presses the flat conductor, the support arm of the locking member is bent by the force from the pressurizing member. Since the locking arm rotates and bends with the connecting portion as a fulcrum, the locking projection of the locking arm is locked with the locking step portion of the flat conductor, so the distance between the locking projection and the connecting portion is Due to being longer than the length of the locking arm itself, the displacement amount of the locking projection is large, that is, the locking force can be increased, and as long as the pressurizing member keeps the closed position, the rotational deflection with the connecting portion as a fulcrum Therefore, even if the flat conductor is pulled strongly in the pulling direction, the locking force is maintained and the flat conductor can be prevented from being pulled out. . In addition, the locking protrusion is not in a position where it contacts when the flat conductor is horizontally inserted before the displacement, and a sufficient displacement force is generated by the subsequent displacement. Therefore, the flat conductor is inserted horizontally without being inserted diagonally. In addition, the insertion force can be extremely small.

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

  In FIG. 1, a connector 1 according to the present embodiment includes a housing 10, a plurality of plate-like terminals 20 implanted in the housing 10, and a plate-like latch having the same thickness and the same shape as the terminals 20. It has the member 30, and the pressurization member 40 supported by the terminal 20 and the latching member 30 so that rotation is possible. 1A is a surface parallel to the plate surface of the terminal 20 at the position of the terminal 20, and FIG. 1B is a surface parallel to the plate surface of the locking member 30 at the position of the locking member 30. It is sectional drawing.

  The housing 10 is made by molding synthetic resin, which is an electrical insulating material, and has a terminal receiving groove 11 and a locking member receiving groove 12 for holding the terminal 20 and the locking member 30, respectively. The terminal receiving groove 11 and the locking member receiving groove 12 extend in parallel to the paper surface, that is, in parallel to the terminals 20 and the plate surface of the locking member 30. In the present embodiment, since the terminal 20 and the locking member 30 are exactly the same, that is, are formed in the same shape with the same thickness, the terminal receiving groove 11 and the locking member receiving groove 12 are formed exactly the same. Yes. Therefore, regarding the form of the groove, only the terminal receiving groove 11 will be described, and the description of the locking member receiving groove 12 will be omitted. The terminal receiving groove 11 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 and the locking member 30 formed while maintaining the flat surface of the metal plate. A plurality are formed at intervals in a direction perpendicular to.

  The housing 10 is formed such that the lower part extends leftward with respect to the upper part. The terminal receiving groove 11 opens upward in the entire upper part of the housing, and partially opens downward in the lower part of the housing. The opening at the lower part of the housing is an intermediate opening 11A formed in a wide range in the middle in the left-right direction and a holding opening 11B formed near the right end. These are formed as an intermediate opening 12 </ b> A and a holding opening 12 </ b> B in the locking member accommodation groove 12.

  When the terminal 20 is inserted downward into the terminal receiving groove 11 of the housing 10, the attached portion 21 to be press-fitted into the holding opening 11 </ b> B and the base portion 22 of the attached portion 21 to the right outside the housing 10. A connecting portion 23 that protrudes in the direction and then bends downward, and a support arm 25 and a contact arm 26 that extend to the left from the connecting portion 24 adjacent to the base portion 22 and are substantially parallel to each other.

  The attached portion 21 has a tapered shape toward the tip and can easily enter the holding opening 11B. A protrusion 21A is formed on the left edge, and the biting into the inner surface of the holding opening 11B is firmly held. It is like that.

  The connecting portion 23 has a lower edge 23A in the height direction, which is substantially at the same level as the bottom surface of the housing 10, and when the connector 1 is disposed on the circuit board, the connecting section 23 is in a position where it contacts the corresponding circuit portion of the circuit board. is there.

  The connecting portion 24 is located adjacent to the base portion 22 of the attached portion 21, and the support arm 25 and the contact arm 26 extend leftward from here. For the support arm 25 and the contact arm 26, it functions as a portion for connecting the two. The connecting portion 24 is wider than the base portion 22 in the height direction and has high rigidity. Therefore, the presence of the constricted portion 27 formed between the connecting portion 24 and the attached portion 21 enables elastic deformation that is flexibly rotated between the connecting portion 24 and the base portion 22.

  The support arm 25 extends to the left and has a distal end portion outside the housing 10. The distal end portion is formed with a concave support portion 25 </ b> A that faces downward. 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.

  Each of the support arm 25 and the contact arm 26 can be elastically bent and deformed, but the contact arm 26 has a smaller arm width than the support arm 25. Is big. Further, since the support arm 25 and the contact arm 26 are firmly connected by the connecting portion 24, when the support arm 25 is bent and deformed, the contact arm 26 is supported by the support arm 25 via the connecting portion 24. It is displaced so as to follow and follow the rotational force in the displacement direction. The contact portion 26 is in the intermediate opening 11A of the housing 10 and is allowed to be bent and displaced.

  A plurality of the terminals 20 are arranged in a direction perpendicular to the paper surface in FIG. 1A, and locking members 30 are disposed adjacent to the terminals 20 at both ends of the arrangement range. As described above, the locking member 30 is shaped while maintaining the flat surface of the metal plate in the same manner as the terminal, and its thickness and shape are exactly the same as those of the terminal 20. In other words, the locking member 30 can also function as a terminal depending on the method of use. Such a locking member 30 has the same shape as the terminal 20, and in FIG. 1B, the corresponding part is indicated by a numeral sign obtained by adding 10 to the sign of each part of the terminal 20. Corresponding to the attached portion 21, projection 21 </ b> A, base portion 22, connecting portion 23, and connecting portion 24 of the terminal 20, the locking member 30 is attached portion 31, protrusion 31 </ b> A, base portion 32, connecting portion 33, connecting portion 34. have. Each part of the locking member 30 corresponding to the support arm 25 and the rotation support part 25A of the terminal 20 and the contact arm 26 and the contact part 26A has the same shape, but according to the difference in function from the terminal 20. The pressure receiving arm 35 and the pressure receiving portion 35A, and the locking arm 36 and the locking projection 36A are named.

  The flat conductor P connected to the connector 1 having such a structure has a support arm 25 such that a connection pad (not shown) formed on the lower surface of the distal end portion is in contact with the contact portion 26A of the terminal 20. And the contact arm 26. Such a flat conductor P is known as, for example, a flexible substrate (FPC), a flat cable, and the like. Usually, a portion inserted into the connector is a surface on which no connection pad is formed, in the illustrated example, the upper side. A reinforcing plate is attached to the surface, and as a locked portion P1 as shown in FIG. 1 (B), for example, at a position corresponding to the locking projection 36A of the locking member 30 when inserted to a predetermined position. A hole shape, a notch shape, and the like are formed.

  In order to increase the contact pressure between the connection pad of the flat conductor P and the contact portion 26 </ b> A of the terminal 20, a pressure member 40 is provided. The pressure member 40 is made of the same synthetic resin as the housing 10, and in FIGS. 1 (A) and 1 (B), an operation part 41 for turning operation is formed at the upper part and a groove part 42 is formed at the lower part. ing. This groove portion 42 corresponds to each terminal 20 and the locking member 30 in the arrangement direction of the terminals 20 so that the distal end portion of the support arm 25 of the terminal 20 and the distal end portion of the pressure receiving arm 35 of the locking member 30 penetrate each other. It is formed in a slit shape at the position to be. 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. The cam portion 43 has a circular shape on the side facing the inside of the groove portion 42, and the opposite side forms a plane parallel to the horizontal plane in the state of FIG. The pressure member 40 is guided by the rotation support portion 25A of the terminal 20 at the arc-shaped portion of the cam portion 43 and the pressure receiving portion 35A of the locking member 30, and the center of the arc-shaped portion is used as an axis. It is freely rotatable between the position in the state (A), (B) and the position in the state in FIGS. 2 (A), 2 (B). The position of the pressure member 40 in FIGS. 1 (A) and 1 (B) is referred to as the open position because the housing is greatly opened so that the flat conductor P can be inserted, and the positions in FIGS. 2 (A) and 2 (B) are Since the flat conductor P is strongly pressed so as to close the pressing member, it is referred to as a closed position.

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

<When assembled>
(1) First, the housing 10 and a predetermined number of terminals 20 and locking members 30 are prepared. In this embodiment, since the terminal 20 and the locking member 30 are made exactly the same as described above, there is no distinction between the two before assembling to the housing 10.
(2) The terminal 20 and the locking member 30 are inserted into the terminal receiving groove 11 and the locking member receiving groove 12 of the housing 10 from above. The attached portions 21 and 31 are press-fitted into the holding openings 11B and 12B, and the projections 21A and 31A are bitten into the groove inner surface, thereby preventing the removal. In this state, most of the contact arm 26 of the terminal 20 and the locking arm 36 of the locking member 30 are accommodated in the intermediate openings 11A and 12A of the housing 10, respectively. The connecting portion 23 of the terminal 20 and the connecting portion 33 of the locking member 30 come to a position where their lower edges 23A and 33A are at substantially the same level as the lower surface of the housing 10. Thus, when the terminal 20 and the locking member 30 are incorporated in the housing 10, the terminals 20 are arranged between the locking members 30 located at both ends.
(3) Next, the pressure member 40 is assembled. For example, in FIG. 1A and FIG. 1B, this incorporation is performed in a state where the pressing member 40 stands up so as to be in the open position, and the support arm 25 of the terminal 20 and the pressure receiving arm 35 of the locking member 30. Is inserted into the groove portion 42 of the pressure member 40 and the cam portion 43 of the pressure member 40 is accommodated in the rotation support portion 25A of the terminal 20 and the pressure receiving portion 35A of the locking member 30. .

<In use>
(1) After the terminal 20 and the locking member 30 are assembled in the housing 10 in this way, the pressure member 40 that is rotatably incorporated into the terminal 20 and the locking member 30 is shown in FIG. Bring to the open position shown in (B). When the pressure member 40 is in this open position, the cam portion 43 of the pressure member 40 is in contact with the rotation support portion 25A of the terminal 20 and the pressure receiving portion 35A of the locking member 30 with the arcuate portion on the upper side. The plane portion of the cam portion 43 is at a position forming a horizontal plane on the lower side. In this open position, the pressure member 40 is opened to the left between the support arm 25 and the contact arm 26 of the terminal 20 and between the pressure receiving arm 35 and the lock arm 36 of the lock member 30.
(2) With the pressurizing member 40 in the open position, the flat conductor P is turned to the right, between the support arm 25 and the contact arm 26 of the terminal 20, and with the pressure receiving arm 35 of the locking member 30. Insert between stop arms 36. The flat conductor P is inserted without difficulty, and the tip of the flat conductor P comes into contact with the regulating wall 13 in the housing and stops at a predetermined insertion position. At this time, the contact portion 26A of the terminal 20 is lightly in contact with the connection pad (see FIG. 1A), and the locking protrusion 36A of the locking member 30 is the hole-shaped covered portion of the flat conductor P. It exists in the position of the lower opening edge of the latching | locking part P1 (refer FIG. 1 (B)).
(3) Thereafter, the pressure member 40 is rotated to the closed position shown in FIGS. 2 (A) and 2 (B). 2A and 2B, the pressing member 40 strongly presses the flat conductor P. 1A and 1B, the distance from the rotation center of the pressure member 40 (the center of the arc-shaped portion of the cam portion 43) to the upper surface of the flat conductor P is short. In (A) and (B), this distance is long, and the pressure member 40 is displaced by pressing the supporting arm 25 of the terminal 20 and the pressure receiving arm 35 of the locking member 30 upward by the cam portion 43 by the difference. (In FIGS. 2A and 2B, the two-dot chain line indicates the position corresponding to the open position in FIGS. 1A and 1B before displacement). Therefore, the pressure on the flat conductor P is also increasing. As a result, the terminal 20 increases the contact pressure with the connection pad of the flat conductor P while the contact portion 26A of the contact arm 26 is elastically displaced downward. On the other hand, in the locking member 30, when the pressure receiving arm 35 is displaced upward, the locking arm 36 is rotated and bent around the connecting portion 34, and the locking projection 36A is displaced upward. Due to this displacement, the locking protrusion 36A penetrates deeply into the locked portion P1 of the flat conductor P and prevents the flat conductor P from coming off. As long as the pressure member 40 is in the closed position, the displacement of the locking protrusion 36A is ensured. The amount of displacement of the locking projection 36A is obtained by the product of the angle of rotation deflection around the connecting portion 34 and the distance from the locking projection 36A to the connecting portion 34, and this distance is the locking arm. Since it is longer than the length of 36 itself, the amount of displacement, that is, the amount of locking, becomes correspondingly large, and the certainty of locking is increased.

  The present invention is not limited to the form shown in FIGS. 1 and 2, and various modifications are possible. 1 and 2, the terminal and the locking member are exactly the same. However, for example, the locking protrusion of the locking member may be formed so as to protrude larger than the contact portion of the terminal. As shown in FIG. 3, the locking member 30 can cause the locking protrusion 36 </ b> A of the locking arm 36 to protrude greatly from the protruding contact portion 26 </ b> A formed on the contact arm 26 of the terminal 20. it can. As the protruding amount is increased, the locking amount is further increased. Further, the locking force can be increased by increasing the locking angle like the locking protrusion 36A '.

As another modification, the terminal and the locking member can be made to have exactly the same shape, and the pressure member can be modified. For example, the portion corresponding to the terminal arrangement range in the terminal arrangement direction is the same as the pressure member shown in FIGS. 1 and 2, and the form is deformed only at the portion corresponding to the locking member outside the arrangement range. . In the example of FIG. 4, the portion corresponding to the locking member is cammed by projecting the lower surface of the operation portion 41 downward relative to the configuration in the arrangement range indicated by the solid line, as indicated by the two-dot chain line. By increasing the distance from the center of the member from d ₀ to d ₁ or by increasing the radius of the downward portion of the cam portion 43 from r ₀ to r ₁ , the flat conductor when the pressure member is in the closed position Due to the reaction force from P, the upward displacement of the pressure receiving arm 35 of the locking member 30 is increased by the protrusion amount increment. Therefore, the rotational deflection of the locking arm 36 around the connecting portion 24 also increases, and the locking amount of the locking projection 36A increases.

  Further, as shown in FIG. 5, the upward radius of the pressure receiving arm 35 is increased by increasing the radius of the upward portion of the cam portion 43 as indicated by a two-dot chain line so that the displacement of the cam portion 43 is increased. Can also be increased.

  By adding a device to the flat conductor connected to the connector of the present invention, the locking amount of the locking protrusion can be further increased. For example, if the thickness of the flat conductor before and after the locked portion in the longitudinal direction is increased stepwise with respect to the locked portion, the amount of locking increases accordingly.
