Description

Flat conductor electrical connector

The present invention relates to a flat conductor electrical connector to which a flat conductor disposed on a mounting surface of a circuit board is connected.

As such a connector, for example, Patent Document 1 discloses an electrical connector for a circuit board, which is an end portion before and after the flat conductor is inserted and removed in a direction parallel to a direction in which the mounting surface of the circuit board is parallel. The connector of Patent Document 1 has a housing that extends in a longitudinal direction in a direction perpendicular to the front-rear direction, and a plurality of terminals that are arranged and held in the housing direction in the longitudinal direction; and The casing is for covering the upper surface of the casing, the two sides, and the outer casing of the metal plate.

The receiving portion of the front end portion of the casing for receiving the flat conductor is formed as a space that opens rearward. The outer casing has an elastic piece which, at both outer positions of the terminal arrangement range, has a strip-like piece portion extending from a rear end of the upper plate portion covering the upper surface of the casing at a lower side than the upper plate portion. The position is formed by folding back toward the front. The elastic piece is a locking portion which is formed to protrude downward at the front end side, and is a flat guide which will be described later. The locked portion of the body can be locked in the pull-out direction (rear) of the flat conductor. The locking portion has an inclined portion that is inclined downward and extends toward the front, and a vertical portion that extends at a right angle to the upper end of the inclined portion, and the vertical portion locks the flat conductor.

The flat type guide system has a notch portion formed at a side edge portion of the front portion thereof, and a portion that protrudes toward the side surface in front of the notch portion functions as a locked portion. When the flat conductor is inserted into the receiving portion of the casing forward, first, the leading edge of the locked portion abuts against the inclined portion of the locking portion of the elastic piece, and is moved in the forward direction. The upward component force of the abutting force of the inclined portion lifts the locking portion to elastically displace the elastic piece upward. When the flat conductor is further inserted forward, when the locked portion reaches a position further forward than the locking portion and the insertion to the predetermined position is completed, the elastic piece is released from the elastic displacement state, and the locking portion protrudes from above. Inside the notch of the flat conductor. As a result, the front surface of the locking portion, that is, the vertical portion is opposed to the rear edge of the locked portion, so that the locked portion can be locked in the pull-out direction. The state prevents inadvertent removal of the flat conductor toward the rear.

[Patent Document 1] Japanese Laid-Open Patent Publication No. 2011-108500

As described above, in the connector of Patent Document 1, the locking portion that can be engaged with the locked portion of the flat conductor is attached to an elastic piece that is elastically displaceable in the vertical direction, and the elastic piece is The strip-like piece portion from which the outer casing extends is formed by buckling in the direction of the plate thickness. Therefore, when the insertion force of the flat type conductor is applied to the flat conductor in a state where the insertion of the flat conductor is completed, the locked portion of the flat conductor strongly abuts against the locking portion from the front. The collision force causes the elastic piece to be elastically displaced upward, and the locked state of the locking portion and the locked portion is released, and the flat conductor is inadvertently pulled out. Further, even if the elastic piece is not elastically displaced, the locking portion or the locked portion may be damaged by the collision force, and the flat conductor may be inadvertently pulled out.

Therefore, for example, it is also conceivable that the elastic piece is less likely to be elastically displaced by increasing the thickness of the elastic piece, and the locked state is easily maintained. However, when the elastic piece is not easily elastically deformed, when the flat type conductor is inserted, Excessive insertion force is required, which in turn creates a new opposite problem that is not easy to insert into a flat conductor.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electrical connector for a flat conductor which can be easily inserted into a flat conductor and can reliably prevent the flat conductor from being detached.

The electrical connector for a flat conductor of the present invention is disposed on A flat conductor extending in the front-rear direction is connected to the mounting surface of the circuit board, and is characterized in that: a housing is provided, and the housing is formed with a receiving portion for inserting the flat conductor forward a space that is open toward the rear; a plurality of terminals that are arranged in a direction parallel to the mounting surface, that is, a direction perpendicular to the front-rear direction, are arranged in the housing direction; and the movable member is movable The member is above the terminal, allowing the flat conductor to be self-contained from the housing in a posture in which the mounting surface is parallel to the closed position in which the flat conductor is inserted into the housing, and in a posture having an angle to the mounting surface. The open position of the body is movably supported by the aforementioned housing.

In the flat connector electrical connector, the movable member has a locked portion formed at both side ends of the flat conductor in an outer position of the arrangement range of the terminals in the arrangement direction. a locking arm portion that is locked in a direction in which the flat conductor is pulled out, the locking arm portion having an elastic arm portion that extends rearward and is elastically displaceable at least in a vertical direction at the closed position; a locking portion that protrudes downward from a lower edge of the rear portion of the elastic arm portion and that is locked by the locked portion of the flat conductor; and a region that protrudes toward the arrangement direction in a region of at least a portion of the side surface including the locking portion a restricted portion, the housing, a member mounted to the housing, or in the aforementioned closed position The movable member has a restricting portion that can be abutted in the pulling direction of the restricted portion at a position further rearward than the restricted portion, and the locking portion is in a state in which the insertion of the flat conductor is completed. The rearward position of the locked portion of the flat conductor is located at a position where the locked portion can be locked in the pull-out direction, and is pulled out toward the rear when the insertion of the flat conductor is completed. When the force acts on the flat conductor, the locked portion of the flat conductor is locked to the locking portion, and the restricted portion abuts against the restricting portion.

In the present invention, when the flat type conductor is connected to the flat type conductor electrical connector, when the flat type conductor is inserted into the receiving portion of the casing with the movable member coming to the closed position, when it is just inserted, The front end of the flat conductor abuts against the locking portion of the locking arm portion of the movable member, and the insertion force is performed while the elastic arm portion of the locking arm portion is elastically displaced upward by the abutting force. A predetermined position of the aforementioned flat type conductor is reached. Further, in a state in which the insertion operation of the predetermined position of the flat conductor is completed, the elastic arm portion is displaced downward to reduce the amount of elastic displacement, and the locking portion is located behind the locked portion of the flat conductor. When the flat-shaped conductor is pulled in the pull-out direction, the flat-shaped conductor is locked in the pull-out direction, and is locked to the locked portion of the flat conductor to prevent the pull-out.

Moreover, in the present invention, the restraining portion that protrudes in the arrangement direction is provided in the locking arm portion of the movable member, and the limit is imposed on the housing, the member attached to the housing, or the movable member in the closed position. In the manufacturing unit, the restricted portion can be abutted in the direction in which the flat conductor is pulled out. Therefore, when the insertion force of the flat conductor is completed and the pulling force toward the rear acts on the flat conductor, not only the locking portion but also the releasing portion receives the pulling force, so the portion can be The burden on the aforementioned locking portion is alleviated. As a result, the elastic arm portion is less likely to be elastically displaced upward, and the locked state of the locking portion and the locked portion can be more reliably maintained, and the inadvertent detachment of the flat conductor can be prevented. Further, since it is not necessary to increase the elastic arm portion or the like in order to maintain the above-described locked state, it is less likely to be elastically displaced, so that it is not easy to insert the flat type conductor. When the flat type conductor is pulled out, the movable member comes to the open position before the drawing is performed. As a result, the locked state of the locked portion with respect to the locked portion and the contact portion of the restricting portion with respect to the restricted portion of the locking arm portion are released, and the flat conductor is allowed to be pulled out rearward.

In the present invention, the restricted portion of the locking arm portion may be a region including a bent portion where the lower edge of the elastic arm portion intersects with the leading edge of the locking portion when viewed in the arrangement direction. The locking portion of the present invention is attached to the rear portion of the elastic arm portion, and protrudes downward from the elastic arm portion, and the restricted portion protrudes laterally toward the terminal arrangement direction. When the rear portion protrudes in two directions, there is a possibility that stress is concentrated in accordance with the pulling force at the periphery thereof, particularly the bent portion. Therefore, when the restricted portion is directly coupled to both the locking portion and the elastic arm portion in the region, the restricting portion can prevent the locking portion itself from being deformed rearward when the pulling force acts on the flat conductor. That is, the reinforcing portion of the deformation in which the buckling angle of the bent portion is enlarged functions. It is also possible to avoid stress concentration in the flexure. As a result, It is possible to more reliably prevent inadvertent detachment of the flat conductor.

In the present invention, the restricting portion may be formed at the same position as the restricted portion of the locking arm portion in the terminal arrangement direction. Alternatively, in the present invention, the elastic arm portion of the locking arm portion may be formed to be long before and after, and may be elastically displaced not only in the vertical direction but also in the terminal arrangement direction, and the rear portion of the locked portion of the flat conductor and At least one of the front portions of the locking portion of the locking arm portion is inclined outward in the arrangement direction as it goes forward, and the restricting portion is in a state before the flat conductor is inserted into the receiving portion of the casing, in the arrangement direction. In a state where the insertion operation of the flat conductor is completed, the pull-out force toward the rear acts on the flat conductor, so that the flat conductor is placed at a position outside the restricted portion of the locking arm portion. When the rear portion of the locking portion has been locked to the front portion of the locking portion, when the elastic arm portion receives the pulling force from the flat conductor at the inclined portion of the front portion, the pulling force is received in the foregoing arrangement direction. The component is elastically displaced outward in the array direction, whereby the restricted portion comes to the same position as the restricting portion in the array direction, and abuts against the restricting portion from the front.

In the present invention, the housing may be in the same position as the restricted portion in the terminal arrangement direction when the pull-out force toward the rear acts on the flat conductor, and the hole portion that can accommodate the restricted portion penetrates in the vertical direction. A portion which is formed on the surface of the inner wall surface forming the hole portion at a position further rearward than the above-mentioned restricted portion and which can be abutted in the direction in which the flat conductor is pulled out can be formed as a restriction portion . When the portion having the inner wall surface of the hole portion penetrating in the vertical direction is used as the restricting portion, the restricted portion is formed in the vertical direction by the fitting of the restricting portion. The larger the size, the larger the contact area between the restricting portion and the restricted portion can be ensured, so that the flat conductor can be more reliably prevented from coming off.

In the present invention, a fastener may be attached to the housing, and a restriction portion may be provided in the fastener. As described above, since the strength of the regulating portion itself can be increased by providing the restricting portion for the fastener, the flat conductor can be more reliably prevented from coming off.

In the present invention, when the insertion force of the flat conductor is completed, when the pulling force toward the rear acts on the flat conductor, not only the locking portion but also the releasing portion receives the pulling force. In part, the burden on the aforementioned locking portion can be alleviated. Therefore, the elastic arm portion is less likely to be elastically displaced upward, and the locked state of the locking portion and the locked portion can be more reliably maintained, and the inadvertent detachment of the flat conductor can be prevented. Further, since it is not necessary to increase the elastic arm portion or the like in order to maintain the above-described locked state, it is less likely to be elastically displaced, so that it is not easy to insert the flat type conductor.

In the illustrated example, as shown in FIG. 4, the restricted portion 47 is provided in a region including a curved portion where the lower surface (the lower surface in FIG. 4) of the elastic arm portion and the upper surface (leading edge) of the locking portion 44A intersect. Thereby, the above-described bent portion which is the base point of the locking portion 44A protruding from the locking arm portion 44 and the stepped corner portion which is the boundary between the restricted portion 47 and the locking arm portion 44 and the locking portion 44A are used. The locking arm portion 44, the locking portion 44A, and the restricted portion 47 are integrally provided to be reinforced each other, so that the strength is improved. When the movable member 40 is in the closed position, the restricted portion 47 enters the concave restricting portion 17C formed in the side regulating portion 17 of the casing, and is adjacent to the upright side edge 17C-1 of the restricting portion 17C in the front-rear direction. Faced, it is in a positional relationship that is restricted from the restriction portion 17C in this direction.

The restricted portion 47 has a polygonal shape as shown in FIG. 3(B) and FIG. 6(C) in which the outer portion is removed from the one end side in the connector width direction of the restricted portion 47, and has a polygonal shape.

However, the position of the locked convex portion is not limited thereto, as long as it is complementary to the locking portion 15B of the casing 10. Correspondingly, no matter which position is available.

The shaft portion 46 is formed in a cylindrical shape extending toward the outer side and the inner side from the end arm portion 42 on one axis extending in the arrangement direction, and is formed as an outer supported portion 46A and an inner supported portion 46B, respectively. The outer supported portion 46A is cut from the base toward the front end, and a part thereof is cut into a slope 46A-1, and the front end surface is semicircular. The inner supported portion 46B is maintained in a cylindrical shape.

As described above, since the end arm portion 42 is housed in the end arm accommodating portion 19B-2 which is formed as a space between the side wall 15 and the side surface regulating portion 17, the outer supported portion 46A is housed in the side wall 15 The support hole portion 15A is rotatably supported by the support hole portion 15A. Further, the inner supported portion 46B is housed in the support concave portion 17B of the side surface regulating portion 17, and the support concave portion 17B is rotatably supported.

The movable member 40 having such a structure is mounted in the following manner. First, the movable member 40 is brought into the two of the housing 10 from above. The side walls 15 are between each other. At this time, in the posture of FIG. 5, the inclined surface 46A-1 of the support portion 46A formed on the outer side of the shaft portion 46 of the movable member 40 is located on the lower side, whereby the two side walls 15 of the casing 10 are thereby inclined to each other by the inclined surface 46a-1 Promote towards the axis. In addition, the outer side portion of the side surface frame portion 10C of the casing 10 is elastically displaced outward in the terminal arrangement direction with the fulcrum portion 10C-1 as a fulcrum, and the outer side of the shaft portion 46 is supported by the support portion 46A from the inside to the casing. The side wall 15 of the support hole 15 of the 10 is supported, and the inner side of the shaft portion 46 is guided by the support portion 46B from above into the support recess 17B of the side surface restriction portion 17 of the casing 10. Then, the movable member 40 is attached to the casing 10 by returning the aforementioned outer portion to a free state.

As shown in FIG. 1 and FIG. 2(A), when the movable member 40 is in the closed position, the main body portion 41 and the locking arm portion 44 of the movable member 40 are housed in the main body housing portion 19B of the casing 10 (refer to FIG. 3). In (A) and (B)), the end arm portion 42 of the movable member 40 is housed in the end arm housing portion 19B-2 of the casing 10 (see FIGS. 3(A) and (B)). As shown in Fig. 1, the movable member 40 is at the closed position, and substantially all of the vertical direction is accommodated in the accommodating portion 19B, and this portion can reduce the vertical dimension of the connector 1 (see also Figs. 6(A) and 7( A), 8(A)). Moreover, since the movable member 40 covers the terminal arrangement range in the closed position, dust, dust, and the like can be prevented from adhering to the first terminal 20 and the second terminal 30. In the present embodiment, substantially all of the movable member 40 in the vertical direction is housed in the accommodating portion 19B. However, instead of this configuration, a part of the movable member 40 in the vertical direction may be accommodated in the accommodating portion, and the accommodated portion may be accommodated. The size of the connector 1 in the up and down direction is reduced.

The fixing fastener 50 is held by the side base portion 14 of the casing 10 at a position close to both ends of the casing 10 in the terminal arrangement direction and in the front-rear direction. The fixing fastener 50 is produced by bending a strip-shaped metal plate having a terminal arrangement direction as a width direction in the thickness direction, and has a holding portion (not shown) held by the casing 10 and a corresponding portion welded to the circuit board. The fixing portion 51. The held portion is integrally molded with the side base portion 14 of the casing 10 and held by the side base portion 14. The lower surface of the fixing fastener 50 extends rearward and is located below the lower surface of the side surface base portion 14 and is welded to a corresponding portion of the circuit board. This soldering facilitates the fixing of the connector 1 to the circuit substrate.

Next, the connection operation between the connector 1 and the flat type conductor C will be described with reference to Figs. 6 to 9 are cross-sectional views of the connector 1 having a plane at right angles to the arrangement direction, showing a state before the flat conductor C is inserted, a state after the flat conductor C is inserted, and a flat conductor being inserted after being inserted. The state in which the outward direction is pulled and the state in which the flat conductor C is to be pulled out. Further, in each of Figs. 6 to 9, (A) shows a cross section of the position of the first terminal 20, (B) shows a cross section of the position of the locking arm portion 44 of the movable member, and (C) shows a movable view. The locking arm portion 44 of the member 40 extends a section of the position of the restricted portion 47 that protrudes.

First, the connecting portions 24, 34 of the first terminal 20 and the second terminal 30 of the connector 1 are soldered to the corresponding circuit portions of the circuit board, and the fixing portions 51 of the fixing fasteners are soldered to the corresponding portions of the circuit board. Since the outer side portion of the side frame portion 10C of the casing 10 is fixed to the circuit board by the welding of the fixing portion 51, the fulcrum portion 10C-1 is restricted as a branch. The elastic displacement of the aforementioned outer portion of the point. As a result, the movable member 40 can be prevented from being detached from the casing 10.

Next, as shown in FIGS. 6(A) to (C), the movable member 40 is brought to the closed position, and the flat conductor C is placed rearward of the connector 1 so as to extend in the front-rear direction along the surface of the circuit board. . Next, the flat conductor C is inserted into the receiving portion 19A of the connector 1 forward. When this insertion is performed, the flat type conductor C is guided to the receiving surface 19A of the casing 10 and the guiding surface 16A toward the receiving portion 19A. Moreover, the flat conductor C inserted into the receiving portion 19A is positioned in the width direction by the side surface regulating surface 17A (see FIGS. 3(A) and (B)) of the side surface regulating portion 17 of the casing 10. Further, the flat conductor C is positioned in the front-rear direction by the front regulating surface 18A of the front regulating portion 18 of the casing 10. Therefore, in the present embodiment, the flat conductor C can be easily brought to a predetermined normal position only by inserting the flat conductor C into the receiving portion 19A.

During the insertion of the flat conductor C into the receiving portion 19A, the flat conductor C enters the transverse U-shaped portion of the first terminal 20, and the transverse U-shaped portion is elastically displaced. Specifically, the front end of the flat conductor C is abutted against the contact convex portion 21A of the upper arm portion 21 of the first terminal 20, and the contact convex portion 21A is pushed up by the upper and lower direction component of the abutting force, and The support convex portion 22A is pressed against the support convex portion 22A of the lower arm portion 22 of the first terminal 20, and the upper arm portion 21 is elastically displaced upward, and the lower arm portion 22 is elastically displaced downward, thereby lowering the upper arm portion. The 21 is pushed forward and moved forward with the lower arm portion 22. As a result, as shown in FIG. 7(A), the flat type conductor C is in a state in which the flat type conductor C is inserted. The contact convex portion 21A of the upper arm portion 21 and the support convex portion 22A of the lower arm portion 22 are sandwiched in the vertical direction, and the circuit portion (not shown) exposed on the upper surface of the flat conductor C is in contact with the upper arm portion 21. The convex portion 21A is in contact with the contact pressure.

In the present embodiment, the contact convex portion 21A of the upper arm portion 21 is located further rearward than the support convex portion 22A of the lower arm portion 22, and the length of the upper arm portion 21 from the base portion (portion connected to the coupling portion 23) to the contact convex portion 21A is The length of the lower arm portion 22 from the base portion to the support convex portion 22A is large, and elastic deflection is likely to occur. Therefore, in a state where the flat conductor C is inserted between the upper arm portion 21 and the lower arm portion 22, the amount of elastic displacement of the upper arm portion 21 is larger than that of the lower arm portion 22.

Further, during the insertion of the flat conductor C into the receiving portion 19A, the front end of the flat conductor C is abutted against the contact convex portion 31A of the upper arm portion 31 of the second terminal 30 by the upper and lower sides of the abutting force. The direction component force pushes up the contact convex portion 31A to elastically displace the upper arm portion 31 upward. As a result, as shown in FIG. 7(A), in the state in which the insertion of the flat conductor C is completed, the contact portion 31A of the circuit portion (not shown) exposed on the upper surface of the flat conductor C and the upper arm portion 31 is Contact pressure contact.

Further, during the insertion of the flat conductor C toward the receiving portion 19A, the ear portion C2 located at a position close to both sides of the flat type conductor C abuts against the card formed at the rear end of the locking arm portion 44 of the movable member 40. The inclined surface 44A-1 of the stopper 44A is elastically displaced upward by the upper and lower direction component of the abutting force, and comes to a position where the flat conductor C is allowed to be inserted. And, when the flat type conductor C is inserted and the ear portion C2 passes through the locking portion At the position of 44A, the locking arm portion 44 is displaced downward to reduce the amount of elastic displacement, and returns to the free state, and protrudes into the notch portion C1 of the flat conductor C. As a result, as shown in FIG. 7(B), in the state where the insertion of the flat conductor C is completed, the locked portion C2A of the flat conductor C is located at the locking surface 44A-2 of the locking portion 44A. Position, therefore, the flat type conductor C is prevented from being pulled out toward the rear. Furthermore, the locking arm portion 44 does not need to be completely returned to the free state. For example, in a state in which a certain amount of elastic displacement remains in the locking arm portion 44, the locking portion 44A protrudes into the notch portion C1 of the flat conductor C and is located at the engageable portion C2A. At the position of the locking, the ear portion C2 of the flat type conductor C is sandwiched in the vertical direction by the locking arm portion 44 and the side surface base portion 14.

Next, when the flat type conductor C is inadvertently subjected to an excessive force toward the rear before the flat type conductor C in the state of FIGS. 7(A) to (C) is intentionally pulled out, the flat type conductor C is to be The locking portion 44A of the locking arm portion 44 provided in the movable member 40 is strongly pulled rearward, and as shown in FIGS. 8(A) to (C), the movable member 40 itself is intended to be displaced rearward. However, even in the movable member 40, the restricted portion 47 that protrudes from the locking arm portion 44 toward the side surface is displaced rearward in the concave regulating portion 17C of the casing, as shown in Fig. 8(C), The restricted edge 47B on the rear side of the restricted portion 47 abuts against the upright side edge 17C-1 on the rear side of the restricting portion 17C, and further movement is prevented. Therefore, there is no possibility that the movable member 40 is displaced or the locking portion 44A is broken. The magnitude of the migration between the offset mechanism movable member and the housing becomes a maximum value.

In the state shown in Figures 7(A) to (C), that is, When the flat type conductor C in the state of being connected to the connector 1 is intentionally pulled out from the connector 1, the movable member 40 in the closed position is rotated to reach the position shown in Figs. 9(A) to (C). Open the location. As shown in FIG. 9(C), when the movable member 40 is in the open position, the locking portion 44A of the locking arm portion 44 that is rotated is located at a position separated upward from the notch portion C1 of the flat conductor C, and the restricted portion 47 is provided. It is located at a position that is separated upward from the restricted portion 17C. In other words, the locking portion 44A releases the locked state of the locked portion C2A of the flat conductor C and the restricted state of the regulating portion 17C to the restricted portion 47, and allows the flat conductor C to be pulled rearward. Then, when the flat conductor C is pulled rearward in this state, the flat conductor C can be easily pulled out.

In the present invention, the restricted portion 47 provided in the locking arm portion 44 is not limited to the form of the concave regulating portion 17C that enters the casing from below when the movable member 40 comes to the closed position, and may be downwardly Enter the side action.

As shown in FIG. 10, the locking portion 44A of the locking arm portion 44 is formed as a slope that is inclined forward from the inner side, and the front end of the locking portion 44A has a shape that matches the front end of the restricted portion 47. When the flat conductor C is at the normal insertion position, the restricted portion 47 is placed on the side of the regulating portion 17 of the casing (see FIG. 11(A)). When the locked portion C2A at the end edge of the ear portion C2 formed by the notch portion C1 of the flat conductor C is formed as an oblique edge suitable for the locking portion 44A, the flat conductor C has a regular position. As shown in Fig. 11(A), the positional relationship between the engaged portion C2A and the locking portion 44A is as a flat conductor. When the C is strongly drawn toward the rear, the locking portion 44A having the flat conductor C in the restricted portion 47 receives the force from the locked portion C2A of the flat conductor C, and the locking arm portion 44 is composed of the side surface. The cam function in which the force is deflected toward the side and displaced by the regulating portion 47 in the same direction enters the restricting portion 17C as shown in Fig. 11(B). The subsequent movement of the restricted portion 47 to the rear by the regulating portion 17C is the same as the above-described example. The relationship between the locking portion 44A and the locked portion C2A may be a non-beveled surface, and at least one of the locking portions may have a cam function as opposed to the other.

In addition, the restraining force of the restricting portion 17C and the restricted portion 47 can be increased without impairing the insertability, and the amount of locking of the restricted portion 47 can be increased as compared with the locking portion 44A. As shown in FIG. 11, the restricting portion 17C is not formed as a concave portion but is formed as a hole portion or a groove portion penetrating to the bottom portion of the casing, and the height of the restrained portion 47 can be increased without changing the height dimension of the locking portion 44A. Therefore, the height of the abutting surface is restricted to be increased, and only the restraining force can be increased.

In the present invention, the restricting portion is not limited to the case of being formed in the casing as shown in the embodiment, and may be formed in a member attached to the casing, for example, formed on the fixing fastener, or formed to be abuttable when the movable member is in the closed position. At the location of the restricted section. Further, the direction in which the restricted portion faces the restricted position toward the restricted position may also face downward.

In the present invention, the locking arm portion provided in the movable member is not limited to the rear side as in the illustrated embodiment, and may extend toward the side in the width direction of the connector. That is, the locking arm portion is formed as a resilient arm portion, and is provided at the front end of the locking arm portion when the movable member is in the closed position. The locking portion may come to a position where the locked portion of the flat conductor is locked.

Further, the movable member does not need to be formed in a plate shape covering the receiving portion of the casing. In the illustrated embodiment, as shown in FIG. 3(A), the housing is not provided with an upper wall covering the terminal arrangement region (the front and rear and the width direction range), and the receiving portion is open to the upper side, but is in the case. When the body is provided to cover the upper wall portion of the terminal arrangement region, the movable member is not required to have a function of covering the receiving portion. Therefore, the movable member may be formed as a side edge and a front end portion of the upper wall portion to surround the three sides. U-shaped frame on the wall.
