In the connector of Patent Document 1, as described above, the contact portion of the terminal is made of strips and has high flexibility. Therefore, if the connector of Patent Document 1 is used in an environment where vibration is intense, the terminal is affected by vibration and causes an unfavorable large elastic displacement. As a result, the flat conductor and the contact portion are connected to each other. It is conceivable that a poor contact state may occur intermittently between them, and there is room for improvement in this respect.

In view of such circumstances, it is an object of the present invention to provide an electric connector for a flat conductor that can maintain a good contact state between the flat conductor and the terminal.

According to the present invention, the above-mentioned problems are solved by the electric connectors for flat conductors according to the following first and second inventions.

<First invention>
The electric connector for a flat conductor according to the first invention is an electric connector for a flat conductor to which a flat conductor extending in the front-rear direction is connected, and at least toward the rear so that the flat conductor is arranged. A receiving portion is formed as a space that is open and expands in the width direction of the connector perpendicular to the front-rear direction and the front-back direction, and the connector thickness direction perpendicular to both the front-rear direction and the connector width direction. It is provided with a pressurizing member provided on one side with respect to the arrangement position of the flat conductor, and the pressurizing member increases the contact pressure between the flat conductor arranged in the receiving portion and the terminal.

In such an electric connector for a flat conductor, in the first invention, the terminal is supported at two positions separated from each other, and can be elastically displaced in the thickness direction of the connector between the two positions. The pressurizing member has a contact portion for contacting the flat conductor between the positions, and the pressurizing member has a pressing portion for pressing the flat conductor from one side in the connector thickness direction. It is characterized in that the pressing portion presses the flat conductor in a state where the mold conductor is arranged in the receiving portion to increase the contact pressure between the flat conductor and the contact portion of the terminal.

In the first invention, after the flat conductor is arranged in the receiving portion, the flat conductor is pressed from one side in the connector thickness direction by the pressing portion of the pressurizing member, so that the flat conductor comes into contact with the terminal. The contact pressure with the part is increased. The terminal has a double-sided beam shape between the two supported positions, and the contact portion is formed between the two positions. Therefore, the contact portion of the terminal has a cantilever-like shape as in the conventional case. The contact pressure between the flat conductor and the contact portion is higher than in the case of. Therefore, even if the connector receives vibration from the outside, the terminal does not cause excessive elastic displacement, and a good contact state between the flat conductor and the terminal is maintained.

In the first invention, the electric connector for a flat conductor has a housing in which the receiving portion is formed and supports the terminals at the two positions, and the pressure member is between the open position and the closed position. When the pressurizing member is in the open position, the flat conductor is allowed to be arranged in the receiving portion, and the pressurizing member is arranged in the receiving portion in the state where the flat conductor is arranged in the receiving portion. May move to the closed position, the pressing portion may press the flat conductor to increase the contact pressure between the flat conductor and the contact portion of the terminal.

<Second invention>
The electric connector for a flat conductor according to the second invention is an electric connector for a flat conductor to which a flat conductor extending in the front-rear direction is connected, and is at least toward the rear so that the flat conductor is arranged. A housing in which a receiving portion is formed as a space that is open and expands in the width direction of the connector perpendicular to the front-rear direction and the front-rear direction, terminals held in the housing, and both directions in the front-rear direction and the width direction of the connector. A pressurizing member provided on one side of the arrangement position of the flat conductor in the thickness direction of the connector and movable between the open position and the closed position, and the pressurizing member is the addition member. When the pressure member is in the open position, the flat conductor is allowed to be placed in the receiving portion, and when the pressure member is in the closed position, the flat conductor placed in the receiving portion and the terminal are used. Increase contact pressure.

In such an electric connector for a flat conductor, in the second invention, the terminal is held in the housing at the position on one end side in the front-rear direction, and at the position on the other end side when the pressurizing member is in the open position. It can be elastically displaced in the thickness direction of the connector, has a contact portion between the position on the one end side and the position on the other end side for contacting the flat conductor, and the pressurizing member is closed. It has a pressing portion that presses the flat conductor from one side in the connector thickness direction when it is in the position, and the pressurizing member moves to the closed position while the flat conductor is arranged in the receiving portion. When this is done, the pressing portion presses the flat conductor so that the terminal is brought into contact with either the housing or the member to which the electric connector for the flat conductor is attached at the position on the other end side. This is characterized by increasing the contact pressure between the flat conductor and the contact portion of the terminal.

In the second invention, when the pressurizing member is in the open position, the terminal is held by the housing at the position on one end side in the front-rear direction, and elastically displaceable in the connector thickness direction at the position on the other end side, that is, , Cantilever-shaped. When the flat conductor is placed in the receiving portion with the pressurizing member in the open position and then the pressurizing member is moved toward the closed position, the pressing portion of the pressurizing member connects the flat conductor to the connector thickness. When pressed from one side in the direction, the terminal is pushed by the flat conductor and elastically displaced toward the other side, and the housing or the electric connector for the flat conductor is attached at the position on the other side. Contact one of them.

In a state where the pressurizing member is moved to the closed position, the terminal is held by the housing at the position on one end side and is supported by the housing or the member at the position on the other end side. Therefore, the contact portion formed in the portion between the position on the one end side and the position on the other end side of the terminal has a double-sided beam shape. Under such a state of the double-sided beam, the pressing portion of the pressurizing member presses the flat conductor toward the contact portion from one side in the connector thickness direction. At this time, since the contact portion has a double-sided beam shape, the contact pressure between the flat conductor and the contact portion is higher than in the case where the contact portion of the terminal has a cantilever-like shape as in the conventional case. Become. Therefore, even if the connector receives vibration from the outside, the terminal does not cause excessive elastic displacement, and a good contact state between the flat conductor and the terminal is maintained.

In the first invention and the second invention, the pressurizing member moves between the open position and the closed position with rotation about an axis extending in the connector width direction on the front end side or the rear end side in the closed position. The pressurizing member is designed to move, and the pressurizing member has the cam portion at the end on the side where the axis line is located in the front-rear direction in the closed position, and the housing or a member attached to the housing. Has a cam receiving portion that presses the cam portion from one side in the connector thickness direction at the closed position, and the pressing portion of the cam portion with the pressurizing member in the closed position. It may be formed on the other side of the connector in the thickness direction.

In such a configuration, when the flat conductor is placed in the receiving portion with the pressure member in the open position and then brought to the closed position, the pressure member is placed in the closed position. The cam portion is pressed by the cam receiving portion from one side of the connector in the thickness direction of the connector. As a result, the pressing force from one side of the pressing portion formed on the cam portion to the flat conductor increases, and the flat conductor and the contact portion of the terminal are brought into contact with each other under a large contact pressure. Can be done.

In the first invention and the second invention, the terminal has a plate surface in which a portion extending in the front-rear direction extends in the front-rear direction and the connector width direction, and is front-to-back at at least one intermediate position in the connector width direction. A slit extending in the direction may be formed, and the contact portion may be formed in a side region located on each of both sides of the slit in the connector width direction.

By forming a slit in the terminal in this way, the terminal is likely to be elastically displaced in the side regions located on both sides of the slit, so that the operation of moving the pressurizing member to the closed position is not so large. Can be done at. At this time, even if the contact pressure between the flat conductor and the contact portion of the terminal is smaller than that in the case where the slit is not formed, the side region has a double-sided beam shape, so sufficient contact pressure is provided. Can be secured.

Further, when the slit is formed in the terminal, another terminal held in a cantilever shape by the housing is provided at a position corresponding to the slit of the terminal in the connector width direction, and the other terminal is provided. The terminal may have a contact portion for contacting the flat conductor located in the slit when viewed in the connector thickness direction. In this way, by providing the other terminals at the positions corresponding to the slits, the number of terminals can be increased without increasing the size of the connector in the connector width direction.

In the first invention and the second invention, the pressing portion of the pressurizing member may have a pressing surface that contacts the flat conductor and presses the flat conductor. When the pressing portion of the pressurizing member has a pressing surface in this way, the flat conductor and the contact portion of the terminal come into surface contact by pressing the flat conductor with the pressing surface at the closed position. Will be. As a result, the contact area becomes large, and a good contact state between the flat conductor and the terminal can be ensured.

In the first invention and the second invention, the contact portion of the terminal may have a plurality of protrusions for contacting the flat conductor. When the contact portion has a plurality of protrusions in this way, when the pressing portion of the pressurizing member presses the flat conductor, the terminal contacts the flat conductor at each of the plurality of protrusions, so that it is flat. A stable contact state between the mold conductor and the terminal can be ensured.

In the first invention and the second invention, a plurality of the terminals may be provided in a state of being arranged in the connector width direction. When a plurality of terminals are provided in this way, it is possible to appropriately mix a plurality of types of terminals such as a signal terminal, a power supply terminal, and a ground terminal.

In the first invention, the pressurizing member has a plate-shaped portion having the connector thickness direction as the plate thickness direction, and the plate-shaped portion has the pressing portion on the plate surface on the other side in the connector thickness direction. The receiving portion is formed as a space between the terminal and the pressing portion of the pressurizing member so that the dimension in the connector thickness direction is smaller than the thickness dimension of the flat conductor. You may be there.

In such a configuration, the dimension of the receiving portion in the connector thickness direction is smaller than the thickness dimension of the flat conductor. Therefore, when the flat conductor is arranged in the receiving portion, the pressing portion of the plate-shaped portion is flat. When the mold conductor is pressed from one side in the connector thickness direction, the contact pressure between the flat conductor and the contact portion of the terminal is increased.

Further, when the pressurizing member has the plate-shaped portion, the pressing portion may be formed so as to project from the plate surface of the plate-shaped portion. By forming the pressing portion so as to protrude, the pressing force of the pressurizing member against the flat conductor is increased, and as a result, the contact pressure between the flat conductor and the contact portion of the terminal can be further increased.

In the present invention, in a state where the pressing portion of the pressurizing member presses the flat conductor from one side in the connector thickness direction, the portion where the contact portion of the terminal is formed has a double-sided beam shape. Therefore, the contact pressure between the flat conductor and the contact portion can be increased as compared with the case where the contact portion of the terminal has a cantilever shape as in the conventional case. Therefore, even if the connector receives vibration from the outside, the terminal does not cause excessive elastic displacement, and a good contact state between the flat conductor and the terminal is maintained.

The metal fitting 40 is attached to the housing 10 from the front of the housing 10, and is fixed to the housing 10 by sandwiching the front wall 12 in the vertical direction between the cover plate portion 41 and the lower plate portion 43. To. Further, with the metal fitting 40 attached to the housing 10, the lower surface of the side fixing portion 45 is at the same height position (position in the vertical direction) as the mounting surface of the circuit board, and is on the mounting surface. It is fixed to the corresponding part by solder connection.

When the pressurizing member 30 is in the open position, as seen in FIG. 4A, the cam receiving portion 46 enters the recess 31B of the pressurizing member 30 from the front and is housed in the recess 31B. At this time, the lower surface of the cam receiving portion 46 is in contact with the upper surface of the cam portion 31A, whereby the pressure member 30 is stably maintained in the open position. On the other hand, when the pressurizing member 30 is rotated to the closed position, as seen in FIG. 4B, the cam receiving portion 46 is exposed from the recess 31B of the pressurizing member 30, and the cam receiving portion is exposed.

In the present embodiment, when the flat conductor C is inserted into the receiving portion 13A of the housing 10 when the pressure member 30 is in the open position, between the lower surface of the cam receiving portion 46 and the upper surface of the flat conductor C. The vertical dimension of the cam portion 31A is smaller than the vertical dimension of the cam portion 31A when the pressurizing member 30 is in the closed position. Therefore, when the pressurizing member 30 is brought to the closed position after the flat conductor C is inserted, the cam portion 31A may press the flat conductor C from above with the pressing surface 31A-1A of the pressing portion 31A-1. It is possible.

In the present embodiment, the cam receiving portion 46 is provided on the metal fitting 40 attached to the connector 1, but it is not essential that the cam receiving portion is provided on the metal fitting, and sufficient strength can be secured for the cam receiving portion. For example, the cam receiving portion may be formed by a part of the housing.

In the present embodiment, the rotation shaft portion 33 of the pressurizing member 30 is provided on the rear end side of the pressurizing member 30 in the closed position, but instead of this, the rotation shaft portion is in the closed position. It may be provided on the front end side of the pressurizing member in. In such a configuration, the cam portion and the cam receiving portion are also provided on the same side as the rotation shaft portion.

The connector 1 according to this embodiment is manufactured as follows. First, in a state where the terminal 20 is arranged in a mold (not shown), the molten resin is injected into the mold and then solidified to form the housing 10. As a result, the terminal 20 is held by the housing 10 by integral molding. Next, the pressure member 30 is arranged from above with respect to the housing 10 while maintaining the posture in the open position, and the rotation shaft portion 33 of the pressure member 30 is housed in the side recess 11C of the housing 10. Then, the connector 1 is completed by attaching the metal fitting 40 to the housing 10 from the front and allowing the cam receiving portion 46 of the metal fitting 40 to enter the recess 31B of the pressurizing member 30 from the front.

Next, the connection operation between the connector 1 and the flat conductor C will be described with reference to FIGS. 1 and 4 (A) and 4 (B). First, the front connection portion 22B and the rear connection portion 23B of the terminal 20 of the connector 1 are solder-connected to the corresponding circuit parts of the circuit board, and the side fixing portions 45 of the metal fittings 40 are solder-connected to the corresponding parts of the circuit board, respectively. Fix it.

Next, as seen in FIGS. 1 and 4A, the flat conductor C is mounted behind the connector 1 on the mounting surface of the circuit board (not shown) with the pressurizing member 30 brought to the open position. Position it so that it extends in the front-back direction along.

Next, the flat conductor C is inserted forward into the receiving portion 13A of the connector 1. At this time, the flat conductor C is guided to the receiving portion 13A by the upper guide surface 11A-1 of the housing 10, the side guide surface 11B, and the lower guide surface 24 of the terminal 20 at both side edges thereof. The insertion of the flat conductor C is completed when the front end of the flat conductor C abuts on the rear surface of the front wall 12 of the housing 10.

Next, the pressurizing member 30 is rotated to bring it to the closed position. When the pressurizing member 30 is brought to the closed position, as seen in FIG. 4B, the cam portion 31A of the pressurizing member 30 enters between the cam receiving portion 46 of the metal fitting 40 and the flat conductor C. The pressurized surface 31A-2A of the compressed portion 31A-2 of the cam portion 31A presses the cam receiving portion 46 from below and also exerts a reaction force (pressing pressure toward downward) against the force (pressing pressure toward upward). Received from the cam receiving unit 46. As the pressed surface 31A-2A receives the pressing force from the cam receiving portion 46 in this way, the pressing portion 31A-1 of the cam portion 31A presses the flat conductor C from above on the pressing surface 31A-1A.

At the position where the flat conductor C is pressed by the pressing surface 31A-1A, the contact portion 21C-2 of the flat conductor C and the terminal 20 is elastically displaced downward, and the flat conductor C and the contact portion 21C-2 are in contact with each other. The contact with pressure causes electrical conduction, and the connection operation between the connector 1 and the flat conductor C is completed. In the present embodiment, since the flat plate portion 21 of the terminal 20 is formed with the slit 21C-1 so that the contact portion 21C-2 is easily elastically displaced, the operation of moving the pressurizing member 30 to the closed position is performed. Can be done with a modest force. Further, in the present embodiment, since the flat conductor C is pressed by the pressing surface 31A-1A, the flat conductor C and the contact portion 21C-2 of the terminal 20 are in surface contact with each other. As a result, the contact area becomes large, and a good contact state between the flat conductor C and the terminal 20 can be ensured.

In the present embodiment, since the contact portion 21C-2 of the terminal 20 has a double-sided beam shape, the flat conductor C has a cantilever-like shape as compared with the conventional case where the contact portion of the terminal has a cantilever shape. The contact pressure between the contact portion 21C-2 and the contact portion 21C-2 can be increased. Therefore, even if the connector 1 receives vibration from the outside, the terminal does not cause excessive elastic displacement, and a good contact state between the flat conductor C and the terminal 20 is maintained.

The present invention is not limited to the embodiments described above, and various modifications are possible. In the present embodiment, the pressing surface 31A-1A of the pressing portion 31A-1 of the pressing member 30 is a flat surface, but instead of this, as shown in FIG. 5, the pressing surface 31A-1A is It may be formed as a curved surface. FIG. 5 is an enlarged cross-sectional view showing a state in which the pressing portion 31A-1 of the pressurizing member 30 is pressing the flat conductor C in the first modification of the first embodiment, with respect to the connector width direction. Shows a cross section on a right-angled surface. In the first modification, the pressing surface 31A-1A has a curved surface that is convexly curved downward, and when the pressure member 30 is in the closed position, the convex curved top surface, that is, in the front-rear direction. The flat conductor C is pressed from above on the surface of the central region. By making the pressing surface 31A-1A such a convex curved surface, the pressing force on the flat conductor C is concentrated at the position of the convex curved top surface, and the flat conductor C and the terminal 20 are brought together with a higher contact pressure. Can be contacted.

Further, in the present embodiment, the upper surface of the contact portion 21C-2 of the terminal 20, that is, the contact surface in contact with the flat conductor C is a flat plate surface, but instead of this, FIG. 6A shows. , (B), a plurality of protrusions 21C-2A may be formed on the upper surface of the contact portion 21C-2, and the plurality of protrusions 21C-2A may come into contact with the flat conductor C. .. 6 (A) and 6 (B) are views showing the connector 1 in the second modification of the first embodiment without the pressurizing member 30 and the metal fitting 40, and FIG. 6 (A) is a perspective view. 6 (B) is a plan view. In FIG. 6, the parts corresponding to the first embodiment are designated by the same reference numerals as those in the first embodiment.

In the second modification, three protrusions 21C-2A protruding from the upper surface (plate surface) of the contact portion 21C-2 are arranged and formed in each contact portion 21C-2 of the terminal 20 in the front-rear direction. There is. Since the contact portion 21C-2 has a plurality of protrusions 21C-2A in this way, when the pressing portion 31A-1 of the pressurizing member 30 presses the flat conductor C from above at the closed position, the terminal Since 20 comes into contact with the flat conductor C at each of the plurality of protrusions 21C-2A, a stable contact state between the flat conductor C and the terminal 20 can be ensured.

Further, in the present embodiment, only one terminal 20 is provided in the connector 1, but instead of this, a plurality of terminals 20 may be provided as shown in FIG. 7. FIG. 7 is a perspective view showing a connector in a third modification of the first embodiment in a state where some terminals are pulled out. In FIG. 7, the parts corresponding to the first embodiment are designated by the same reference numerals as those in the first embodiment.

FIG. 7 shows an example in which four terminals 20 are provided. These four terminals 20 have a shape as if the terminal 20 of the first embodiment is divided in the connector width direction, and the two terminals 20A at both ends in the connector width direction are narrow in the same direction and intermediate. The two terminals 20B at the positions have a wide shape. When a plurality of terminals 20 are provided in this way, these terminals 20 can also be used as different types of terminals. Therefore, for example, a signal terminal, a power supply terminal, a ground terminal, and the like can be appropriately selected and mixed.

In the third modification shown in FIG. 7, the narrow terminal 20A (referred to as “narrow terminal 20A”) is held by the housing 10 at two positions, the front end side and the rear end side in the front-rear direction, and has a contact portion. 21C-2 has a double-sided beam shape. On the other hand, the wide terminal 20B (referred to as "wide terminal 20B") is held only on the front end side by the housing 10, and the contact portion 21C-2 has a cantilever shape. However, when the connector 1 is arranged on the circuit board, the front connection portion 22B and the rear connection portion 23B are in contact with the corresponding circuit portion of the circuit board at both the narrow terminal 20A and the wide terminal 20B. , Similar to the first embodiment, the contact portion 21C-2 has a double-sided beam shape.

Further, as a further modification of the third modification, even when the connector is arranged on the circuit board, at least some of the terminal contact portions have a cantilever-like shape, and after the flat conductor is inserted, By bringing the pressurizing member to the closed position, the contact portion of the terminal may be shaped like a double-sided beam. For example, when the pressure member 30 is in the open position while the wide terminal 20B shown in FIG. 7 is held in the shape of a cantilever, the flat plate portion 21 of the wide terminal 20B is slightly tilted toward the rear. Can be formed in a flexible shape.

When the wide terminal 20B has such a shape, when the connector 1 is arranged on the circuit board, the rear connection portion 23B of the wide terminal 20B is floating from the corresponding circuit portion of the circuit board. Since the contact portion is not in contact with the corresponding circuit portion, the contact portion 21C-2 of the wide terminal 20B has a cantilever shape. Then, after the flat conductor C is inserted, the pressure member 30 is rotated to a closed position, and when the flat conductor C is pressed from above by the pressing portion 31A-1 of the pressure member 30, the flat conductor C is pressed. The contact portion 21C-2 of the wide terminal 20B pressed from above via C is elastically displaced downward. Along with this elastic displacement, the rear connection portion 23B of the wide terminal 20B is also displaced downward, so that the rear connection portion 23B comes into contact (contact) with the corresponding circuit portion of the circuit board, and as a result, the contact portion 21C -2 becomes a double-sided beam.

Further, here, an example has been described in which the contact portion 21C-2 becomes a double-sided beam shape when the rear connection portion 23B of the wide terminal 20B abuts on the circuit board which is a member to which the connector is attached. The member to be brought into contact is not limited to the member to which the connector is attached, and may be a housing. When abutting on the housing, for example, when only one end side portion of the terminal is held by the housing and the pressurizing member is rotated to the closed position after inserting the flat conductor, the other end side portion (free end) of the terminal is held. By bringing the side portion) into contact with a part of the housing, the contact portion located between the one end side portion and the other end side portion becomes a double-sided beam shape.

<Second embodiment>

A guide member 110 made of an electrically insulating material that supports the terminal 120 and the pressure member 130 at intervals in the vertical direction, and a metal plate that holds the guide member 110, the terminal 120, and the pressure member 130. It has a holding member 140 of the above.

The terminal 120 has a flat plate shape extending in the front-rear direction and the connector width direction, and is held by holding members 140 at both ends in the connector width direction. That is, the terminal 120 is supported at both end positions in the connector width direction. A contact portion 121 in contact with the flat conductor F is formed in the intermediate region of the terminal 120 in the connector width direction. The contact portion 121 has a double-sided beam shape between both ends thereof, and can be elastically displaced in the plate thickness direction (vertical direction) thereof. In the present embodiment, the terminal 120 is used as a power supply terminal, but the type of the terminal is not limited to this, and for example, it can be used as a signal terminal.

The pressurizing member 130 is formed as a flat plate-shaped portion extending in the front-rear direction and the connector width direction, and is located above the terminal 120 so as to face the terminal 120. The pressurizing member 130 is positioned with a gap between it and the terminal 120 in the vertical direction. This gap (the space between the pressurizing member 130 and the terminal 120) penetrates in the front-rear direction, and is formed as a receiving portion 102 that can receive the flat conductor F from the rear. The vertical dimension of the receiving portion 102 is substantially equal to the thickness dimension of the flat conductor F in a range excluding the portion where the pressing portion 131 described later is formed.

Like the terminal 120, the pressurizing member 130 is held by the holding member 140 at both end positions in the connector width direction. A pressing portion 131 projecting downward is formed in the intermediate region of the pressurizing member 130 in the connector width direction. The pressing portion 131 is formed by, for example, pressing the plate surface of the pressurizing member in the plate thickness direction. The pressing portion 131 projects from the receiving portion 102, and the vertical dimension between the lower surface of the pressing portion 131 and the upper surface of the terminal 120 is slightly smaller than the thickness dimension of the flat conductor F. There is. The lower surface of the pressing portion 131 is a flat surface, and forms a pressing surface 131A that presses the flat conductor F inserted into the receiving portion 102 from above.

The guide member 110 is a spacer extending forward from each of a guide portion 111 (see FIG. 8A) located on the rear end side of the terminal 120 and the pressurizing member 130 and both end positions of the guide portion 111 in the connector width direction. It has a part 112 (see FIG. 8B). The guide portion 111 has a downward guide portion 111A extending over the entire area of the terminal 120 in the connector width direction at the same position as the terminal 120 in the vertical direction, and a side guide portion 111B extending upward from both ends of the downward guide portion 111A. And have.

As seen in FIG. 8A, the lower guide portion 111A is formed with its upper surface as a lower guide surface 111A-1 that inclines upward toward the front. The side guide portion 111B has a side guide surface 111B-1 that inclines inward in the connector width direction inward in the connector width direction and inwardly inclined in the connector width direction toward the front. The downward guide surface 111A-1 and the side guide surface 111B-1 are adapted to guide the flat conductor F to the receiving portion 102 at the start of inserting the flat conductor F.

As seen in FIG. 8B, the spacer portion 112 is provided at a position corresponding to both ends of the terminal 120 and the pressurizing member 130 in the connector width direction. The spacer portion 112 is located between the terminal 120 and the pressurizing member 130 in the vertical direction, and extends over the entire area of the terminal 120 and the pressurizing member 130 in the front-rear direction. The spacer portion 112 is indirectly held by the holding member 140 in a state of being sandwiched between the terminal 120 and the pressurizing member 130. The vertical dimension of the spacer portion 112 is slightly larger than the thickness dimension of the flat conductor F, and as a result, the receiving portion 102 is formed between the terminal 120 and the pressure member 130. That is, the spacer portion 112 functions as a spacer for securing the receiving portion 102 between the terminal 120 and the pressurizing member 130.

The holding member 140 is made by bending a metal plate member in the plate thickness direction, and as seen in FIG. 8A, extends over the entire area of the terminal 120 and the pressurizing member 130 in the front-rear direction. , As seen in FIG. 8B, it has a substantially S-shape when viewed in the front-rear direction. The holding member 140 includes a holding portion 141 for sandwiching and holding the terminal 120, the pressurizing member 130, and the spacer portion 112 of the guide member 110, a transition portion 142 extending downward from the holding portion 141, and the transition portion 142. It has a connecting portion 143 extending outward from the lower end of the connector in the width direction of the connector.

The holding portion 141 includes an upper holding plate portion 141A located along the upper surface of the pressurizing member 130, a lower holding plate portion 141B located along the lower surface of the terminal 120, and an upper holding plate portion 141A and a lower holding plate portion 141B. It has a connecting portion 141C for connecting the outer end portions of the connector in the width direction of the connector. The upper holding plate portion 141A has a smaller dimension in the connector width direction than the lower holding plate portion 141B, and the holding portion 141 has a substantially horizontal J-shape when viewed in the front-rear direction.

The vertical dimension between the upper holding plate portion 141A and the lower holding plate portion 141B is slightly smaller than the total of the vertical dimensions of the terminal 120, the pressurizing member 130, and the spacer portion 112 of the guide member 110. There is. Therefore, the holding portion 141 can hold the terminal 120, the pressurizing member 130, and the spacer portion 112 in a state of being pinched by the elastic displacement of the upper holding plate portion 141A and the lower holding plate portion 141B.

The transition portion 142 extends downward from the inner end portion of the lower holding plate portion 141B in the connector width direction, and forms a gap between the circuit board (not shown) and the terminal 120 (FIG. 8 (FIG. 8). B) See). The connection portion 143 is capable of contacting the corresponding circuit portion on the mounting surface of the circuit board on the lower surface thereof. By soldering the connection portion 143 to the corresponding circuit portion, the terminal 120 and the corresponding circuit portion are electrically conductive.

The connector 101 is manufactured as follows. First, the spacer portion 112 of the guide member 110 is sandwiched between the end portion of the terminal 120 in the connector width direction and the end portion of the pressurizing member 130 in the connector width direction. Next, while maintaining this sandwiched state, the end portion of the terminal 120, the end portion of the pressure member 130, and the spacer portion 112 are placed between the upper holding plate portion 141A and the lower holding plate portion 141B of the holding member 140. Enter the gap from behind. As a result, the terminal 120 and the pressurizing member 130 are held by the holding portion 141 of the holding member 140 in a state where the spacer portion 112 is sandwiched, and the connector 101 is completed.

Next, the connection operation between the connector 1 and the flat conductor C will be described. First, the connection portion 143 of the holding member 140 of the connector 101 is solder-connected to the corresponding circuit portion of the circuit board. Then, as seen in FIG. 8A, the flat conductor F is positioned behind the connector 1 so as to extend in the front-rear direction along the mounting surface of the circuit board (not shown).

Next, the flat conductor F is moved forward and inserted into the receiving portion 102 of the connector 101 from the rear. At this time, the flat conductor F is guided to the receiving portion 102 by the downward guide surface 111A-1 and the side guide surface 111B-1 of the guide portion 111 of the guide member 110. The flat conductor F is inserted until the front end of the flat conductor F reaches the vicinity of the front ends of the terminal 120 and the pressurizing member 130.

When the flat conductor F is inserted in this way, the pressing portion 131 of the pressurizing member 130 presses the flat conductor F from above on the pressing surface 131A. As a result, as seen in FIGS. 8B and 8C, at the position where the flat conductor F is pressed by the pressing surface 131A, the contact portion 121 between the flat conductor F and the terminal 120 is elastically displaced downward. , The flat conductor F and the contact portion 121 come into contact with each other with high contact pressure to electrically conduct, and the connection operation between the connector 1 and the flat conductor F is completed.

As described above, in the present embodiment, the flat conductor F can be easily connected to the connector 101 simply by inserting the flat conductor F into the receiving portion 102. Further, since the contact portion 121 of the terminal 120 has a double-sided beam shape, the flat conductor F and the contact portion 121 have a shape as compared with the case where the contact portion of the terminal has a cantilever shape as in the conventional case. The contact pressure can be increased. Therefore, even if the connector 101 receives vibration from the outside, the terminal 120 does not cause an excessive elastic displacement, and a good contact state between the flat conductor F and the terminal 120 is maintained.
