Description

  The present invention relates to an electrical connector for a flat conductor that is arranged on a mounting surface of a circuit board and to which a flat conductor is connected.

  As this type of connector, for example, Patent Document 1 discloses an electrical connector for a circuit board in which a front end portion of a flat conductor is inserted and removed in a front-rear direction which is one direction parallel to a mounting surface of the circuit board. The connector of Patent Document 1 includes a housing that extends in a direction perpendicular to the front-rear direction as a longitudinal direction, a plurality of terminals that are arranged and held in the housing with the longitudinal direction as an arrangement direction, an upper surface of the housing, A shell made of a metal plate attached to the housing so as to cover both side surfaces and the front surface.

  The housing is formed as a space in which a receiving portion for receiving the front end portion of the flat conductor is opened rearward. The shell is an elastic piece formed by folding back a band-like piece portion extending from the rear end of the upper plate portion covering the upper surface of the housing at the both outer positions in the terminal arrangement range. have. The elastic piece is a locking portion that protrudes downward on the front end side, and can be locked in the flat conductor extraction direction (rear) with respect to a locked portion of the flat conductor described later. ing. The engaging portion has an inclined portion that extends downward and inclines toward the front, and a vertical portion that is bent and extended perpendicularly upward at the front end of the inclined portion, and the vertical portion is a flat conductor. It is intended to lock against.

  The flat conductor has a notch formed at the front edge of the flat conductor, and a portion protruding toward the side in front of the notch functions as a locked portion. When the flat conductor is inserted forward into the receiving portion of the housing, first, the front edge of the locked portion comes into contact with the inclined portion of the locking portion of the elastic piece and moves forward. In the process, the elastic piece is elastically displaced upward so as to lift the locking portion by the upward component force of the contact force against the inclined portion. Further, when the flat conductor is inserted forward and the locked portion reaches the front position from 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 enters the cutout portion of the flat conductor from above. As a result, the front surface of the locking portion, that is, the vertical portion is positioned opposite to the rear edge of the locked portion, so that the locking portion can be locked in the extraction direction. Thus, inadvertent extraction of the flat conductor facing backward is prevented.

JP2011-108500A

  As described above, in the connector of Patent Document 1, the locking portion that can be locked with the locked portion of the flat conductor is formed by bending the strip-shaped piece portion extending from the shell in the plate thickness direction. The elastic piece is elastically displaced in the vertical direction. Accordingly, when a strong pulling force acting backward 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 is strongly pressed from the front with respect to the locking portion. When the elastic piece is elastically displaced upward by the abutting impact force, the locking state between the locking portion and the locked portion is released, and the flat conductor may be inadvertently pulled out. . Even if the elastic piece is not elastically displaced, the locking portion or the locked portion may be damaged by the impact force described above, and the flat conductor may be inadvertently pulled out.

  Thus, for example, it may be possible to easily maintain the locked state by increasing the thickness of the elastic piece so that the elastic piece is less likely to be elastically displaced. However, when inserting the flat conductor, an excessive insertion force is required, which makes it difficult to insert the flat conductor easily.

  In view of such circumstances, an object of the present invention is to provide a flat conductor electrical connector that can easily insert a flat conductor and reliably prevent the flat conductor from coming off.

An electrical connector for a flat conductor according to the present invention is an electrical connector for a flat conductor that is arranged on a mounting surface of a circuit board and is connected to a flat conductor that extends in the front-rear direction. The housing in which the receiving part is formed as a space opened at least rearward so as to be inserted toward the rear side, and the direction perpendicular to the front-rear direction and in one direction parallel to the mounting surface as, and a closed position to allow a plurality of terminals which are arranged and held in the housing, above the said receiving portion in parallel orientation with respect to the mounting surface of the insertion of the flat conductive to said housing, said mounting surface And a movable member supported by the housing so as to be movable between an open position allowing the flat conductor to be extracted from the housing in a posture having an angle with respect to the housing.

  In such an electrical connector for a flat conductor, in the present invention, the movable member is positioned outside the terminal arrangement range in the arrangement direction with respect to the locked portions formed on both side ends of the flat conductor. A locking arm portion that can be locked in the pulling direction of the flat conductor, the locking arm portion extending toward the rear, and an elastic arm portion that is elastically displaceable at least in the vertical direction at the closed position; In the region including the locking part that protrudes downward from the lower edge of the rear part of the elastic arm part and can be locked to the locked part of the flat conductor, and at least a part of the side surface of the locking part The housing, a member attached to the housing, or the movable member in the closed position is located at a position behind the regulated portion at the regulated portion. It has a restricting part that can be contacted in the above-mentioned extraction direction. In a state in which the engagement is completed, the locking portion is positioned so as to be locked in the extraction direction with respect to the locked portion at a position behind the locked portion of the flat conductor, and the flat conductor is inserted. When a backward pulling action acts on the flat conductor in a state where the flat conductor is completed, the locked portion of the flat conductor is locked to the locking portion, and the restricted portion is the restricting portion. It is characterized by abutting on.

  In the present invention, when the flat conductor is inserted into the receiving portion of the housing with the movable member brought to the closed position when the flat conductor is connected to the electric connector for the flat conductor, the flat conductor is initially inserted. The front end of the conductor comes into contact with the locking portion of the locking arm portion of the movable member, and the elastic arm portion of the locking arm portion is elastically displaced upward by the contact force to reach a predetermined position of the flat conductor. The insertion can proceed. Then, in a state where the insertion of the flat conductor to the predetermined position is completed, the elastic arm portion is displaced downward so as to reduce the amount of elastic displacement, and the locking portion is a locked portion of the flat conductor. It is positioned so that it can be locked in the above-mentioned extraction direction with respect to the locked portion at a rear position of the flat conductor, and when the flat conductor is pulled in the pulling direction, it is locked to the locked portion of the flat conductor. To prevent withdrawal.

  Further, in the present invention, a restricted portion that protrudes in the arrangement direction is provided on the locking arm portion of the movable member, and is provided on the housing, the member attached to the housing, or the movable member in the closed position. The restricted portion can be brought into contact with the restricting portion in the pulling-out direction of the flat conductor. Therefore, when a backward pulling action acts on the flat conductor in a state where the insertion of the flat conductor is completed, the pulling output can be received not only by the locking part but also by the restriction part. Since this is possible, the burden on the locking portion is reduced accordingly. As a result, the elastic arm portion is less likely to be elastically displaced upward, the locking state between the locking portion and the locked portion is more reliably maintained, and inadvertent removal of the flat conductor is prevented. In addition, since it is not necessary to make the elastic arm portion thick to make it difficult to be elastically displaced in order to maintain the locked state, it is not difficult to insert the flat conductor. When the flat conductor is extracted, the movable member is brought to the open position prior to extraction. As a result, the locked state of the locking portion with respect to the locked portion and the contact state of the restricting portion with respect to the restricted portion of the locking arm portion are released, and the flat conductor is pulled out rearward. Is acceptable.

  In the present invention, the restricted portion of the locking arm portion is provided in a region including a bent portion where the lower edge of the elastic arm portion and the front edge of the locking portion intersect when viewed in the arrangement direction. Also good. In the present invention, the locking portion protrudes downward from the elastic arm portion at the rear portion of the elastic arm portion, and the restricted portion protrudes in the terminal arrangement direction, that is, in the lateral direction. Protruding in the two directions at the rear portion may cause stress concentration due to the extraction force in the periphery, particularly in the bent portion. Therefore, if the regulated portion is directly connected to both the latching portion and the elastic arm portion in the region, the regulating portion is configured such that when the unplugging force acts on the flat conductor, the latching portion It functions as a reinforcing portion that prevents deformation toward the rear of itself, that is, deformation that increases the bending angle of the bent portion. That is, stress concentration at the bent portion can be avoided. As a result, inadvertent disconnection of the flat conductor can be prevented more reliably.

  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, since the elastic arm portion of the locking arm portion is formed long in the front and rear direction, the elastic arm portion can be elastically displaced in the arrangement direction of the terminals in addition to the vertical direction. At least one of the rear part and the front part of the engaging part of the engaging arm part is inclined outward in the arrangement direction as it goes forward, and the restricting part is before the flat conductor is inserted into the receiving part of the housing. In this state, in the arrangement direction, it is provided outside the regulated portion of the locking arm portion, and in the state where the insertion of the flat conductor is completed, there is no rearward output to the flat conductor. In operation, when the rear portion of the locked portion of the flat conductor is locked to the front portion of the locking portion, the elastic arm portion receives an output from the flat conductor at the inclined portion of the front portion. And elastically displacing outward in the arrangement direction in response to a component force in the arrangement direction of the output force. Ri, the controlled portion may be adapted to abut from the front the restricting portion is brought to the regulating unit and the same position in the arrangement direction.

  In the present invention, the housing has a hole portion that can accommodate the regulated portion in the vertical direction at the same position as the regulated portion in the arrangement direction of the terminals when a backward pulling action is applied to the flat conductor. A surface that is formed so as to penetrate and that is positioned so as to be able to come into contact with the regulated portion in the extraction direction of the flat conductor at a position behind the regulated portion among the inner wall surfaces forming the hole portion. The part which it has may be formed as a control part. As described above, when a portion having an inner wall surface that forms a hole penetrating in the vertical direction is used as the restriction portion, the restriction portion and the covered portion are formed by forming the restriction portion large in the vertical direction according to the restriction portion. Since a large contact area with the restricting portion can be ensured, the flat conductor can be more reliably prevented from coming off.

  In the present invention, a metal fitting may be attached to the housing, and a restricting portion may be provided on the metal fitting. By providing the restricting portion on the metal fitting in this way, the strength of the restricting portion itself can be increased, so that the flat conductor can be prevented from coming off more reliably.

  In the present invention, when the flat conductor is completely inserted and a backward pulling action is applied to the flat conductor, the pulling force is received not only by the locking portion but also by the restricting portion. Therefore, the load on the locking portion is reduced accordingly. Therefore, the elastic arm portion is less likely to be elastically displaced upward, the locking state between the locking portion and the locked portion is more reliably maintained, and inadvertent disconnection of the flat conductor is prevented. In addition, since it is not necessary to make the elastic arm portion thick to make it difficult to be elastically displaced in order to maintain the locked state, it is not difficult to insert the flat conductor.

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

  FIG. 1 is a perspective view showing a flat conductor electrical connector 1 (hereinafter referred to as “connector 1”) according to the present embodiment together with a flat conductor C, and shows a state before the flat conductor C is inserted. The front is shown as the insertion direction P in the middle. In the connector 1 of FIG. 1, a housing 10 that holds a mixture of two types of terminals, a first terminal 20 and a second terminal 30, supports a movable member 40 that can rotate between a closed position and an open position. FIG. 1 is a perspective view of the state before the flat conductor is inserted when the movable member 40 is in the closed position, and FIG. 2A is a plan view of the connector of FIG. These are top views which show only the movable member of the connector of FIG. 2 (A). 3 is a perspective view showing the connector of FIG. 1 with the movable member 40 removed from the housing 10. FIG. 4 is a perspective view of the connector of FIG. 3, with one end (right end) of the housing and the movable member removed. It is a perspective view shown with the flat type conductor before insertion. FIG. 5 is a perspective view of the connector in a state where the inserted flat conductor is provided for extraction and the movable member 40 is in the open position. 1 is disposed on a mounting surface of a circuit board (not shown), and the flat conductor C is connected to electrically connect the circuit board and the flat conductor C. Here, the “circuit board” means a board on which a circuit portion connected to the connector terminal is formed. This “board” is not only a plate-like member having a high rigidity but also a flexible having a low rigidity. A sheet-like member is also included.

  The flat conductor C has a strip shape extending in the front-rear direction, and a plurality of circuit portions (not shown) extending in the front-rear direction are arranged in the width direction (a direction perpendicular to the front-rear direction). The circuit portion is embedded in the insulating layer of the flat conductor C, extends in the front-rear direction, and reaches the front end position of the flat conductor C. Further, only the front end portion of the circuit portion is exposed on the upper surface of the flat conductor C, and can be brought into contact with a first terminal 20 and a second terminal 30 of the connector 1 described later. Further, the flat conductor C has notches C1 formed on both side edges of the front end side portion, and the rear end edge of the ear portion C2 positioned in front of the notch C1 is a latch of the connector 1 described later. It functions as a locked portion C2A that locks with the portion 44A.

  The connector 1 includes a housing 10 made of an electrical insulating material, a plurality of metal first terminals 20 and second terminals 30 arranged and held in the housing 10 (see also FIGS. 3A and 3B). ), A movable member 40 made of an electrical insulating material supported by the housing 10 so as to be rotatable between a closed position and an open position, which will be described later, and a metal fixing bracket 50 held by the housing 10. In FIG. 1, the flat conductor C is inserted and connected in the arrow direction from the rear.

Prior to description of the detailed configuration of the connector 1, first, an outline of operations of inserting and extracting the flat conductor C from the connector 1 will be described. Before the flat conductor C is inserted into the connector 1, as shown in FIG. 1, the movable member 40 of the connector 1 is in a posture parallel to the mounting surface (not shown) of the circuit board. In the closed position, insertion of the flat conductor C is allowed. The flat conductor is brought into contact with the first terminal 20 at the front end edge thereof and elastically displaces the contact portion of the first terminal 20 to enable insertion to a predetermined position. Further, even after the flat conductor C is inserted and connected, the movable member 40 is maintained in the closed position when the connector 1 is in use, and the locking portion 44A of the movable member 40 and the flat shape are maintained as will be described later. Since the locked portion C2A of the conductor C is positioned so as to be locked, and further, the controlled portion of the movable member is in a position where it can come into contact with the limiting portion of the housing, and the flat conductor has an excessive output power. When the flat conductor moves the movable member rearward, the regulated portion of the movable member comes into contact with the regulating portion of the housing and the movement is prevented. Further, when the flat conductor C is pulled out when the connector 1 is not used, as shown in FIG. 5, the movable member 40 is rotated in the upright direction to have an angle with respect to the mounting surface of the circuit board. By being brought to the open position which makes the posture, the locked state of the locking portion 44A of the movable member 40 with respect to the locked portion C2A of the flat conductor C is released, and the controlled portion of the movable member 40 is also connected to the housing. The locked state with the restricting portion is released and the flat conductor C is allowed to be pulled out rearward.

  As is often seen in FIGS. 3 and 6A, 6B, the housing 10 is formed with a space 19 having the following receiving portion 19A, accommodating portion 19B, and elastic displacement allowing portion 19C. 6A and 6B, the space 19 includes a receiving portion 19A for receiving the flat conductor C from the rear, and a position above the receiving portion 19A and in the closed position. An accommodating portion 19B for accommodating a certain movable member 40, and an elastic displacement allowing portion 19C that is located below the receiving portion 19A and allows an elastic displacement downward of the lower arm portion 22 of the first terminal 20 are provided. Yes.

  The receiving portion 19A is located above the rear terminal holding portion 13 and below the movable member 40 in the closed position in the vertical direction, and is formed between the two side regulating portions 17 in the terminal arrangement direction. . The receiving portion 19A is opened rearward so that the flat conductor C can be received.

  The accommodating portion 19B is located above the receiving portion 19A, communicates with the receiving portion 19A, and is formed between the two side walls 15 in the arrangement direction. The accommodating portion 19B is opened upward and can accommodate the movable member 40 brought to the closed position. As can be seen in FIGS. 3A and 3B, the accommodating portion 19 </ b> B extends to both the inner and outer sides with respect to the side regulating portion 17 in the terminal arrangement direction, and is positioned between the side regulating portions 17. The inner space is formed as a main body housing portion 19B-1 for housing a main body portion 41 and a locking arm portion 44 described later of the movable member 40. In addition, an outer space located between the side wall 15 and the side restricting portion 17 in the terminal arrangement direction in the accommodating portion 19B is an end arm accommodating portion for accommodating an end arm portion 42 described later of the movable member 40. It is formed as 19B-2. The accommodating portion 19B is formed from the position of the rear ends of upper arms 21 and 31 of the first terminal 20 and the second terminal 30 described later to the front end of the housing 10 in the front-rear direction. In the present embodiment, the accommodating portion 19B is positioned above the receiving portion 19A. However, this “located above” means that the accommodating portion 19B overlaps the receiving portion 19A in the vertical direction. Including the state that is.

  The elastic displacement allowing portion 19C is formed by a space that is surrounded by a rectangular frame-shaped portion of the housing 10 (a portion including the front frame portion 10A, the rear frame portion 10B, and the side frame portion 10C) and penetrates in the vertical direction. Yes. The elastic displacement allowing portion 19 </ b> C accommodates a lower arm portion 22 of the first terminal 20 described later, and allows the elastic displacement of the lower arm portion 22 downward.

  In the present embodiment, the terminal includes two types of first terminal 20 and second terminal 30 having different shapes. The first terminal 20 and the second terminal 30 have a cross-sectional shape as seen in FIGS. 6 to 9 and are alternately arranged.

  The first terminal 20 is formed by bending a strip-shaped metal plate with the terminal arrangement direction in the width direction in the plate thickness direction, extending in the front-rear direction (left-right direction in FIGS. 6 to 9), and elastically moving in the up-down direction. The upper arm portion 21 and the lower arm portion 22 are possible, a connecting portion 23 that connects the front ends of the upper arm portion 21 and the lower arm portion 22, and a connecting portion 24 that extends rearward from the lower arm portion 22. . The first terminal 20 has the upper arm portion 21, the lower arm portion 22, and the connecting portion 23 as described above, thereby forming a horizontal U-shaped portion that opens toward the rear. The U-shaped portion allows the flat conductor C to be received from the left side, and the flat conductor C can be clamped between the upper arm portion 21 and the lower arm portion 22 by being elastically displaced at the time of reception. The portion near the rear end of the lower arm portion 22 is formed as a held portion 22B that is held by integral molding with the rear terminal holding portion 13 of the housing 10.

  The connection portion 24 of the first terminal 20 extends in a crank shape from the rear terminal holding portion 13 to the rear in a state where the first terminal 20 is held by the rear terminal holding portion 13 of the housing 10. The connecting portion 24 has a lower surface positioned below the lower surface of the rear terminal holding portion 13 and is connected to the circuit portion of the circuit board by soldering.

  The second terminal 30 is formed by bending a band-shaped metal plate having the terminal arrangement direction in the width direction in the plate thickness direction, and has a substantially crank shape as a whole. The second terminal 30 includes an upper arm portion 31 that extends in the front-rear direction and can be elastically displaced in the vertical direction, a lower arm portion 32 that extends forward from the upper arm portion 31, a front end of the upper arm portion 31, and a rear end of the lower arm portion 32. And a connecting portion 34 extending forward from the lower arm portion 32 and having the substantially crank shape.

  The upper arm portion 31 of the second terminal 30 is narrower than the lower arm portion 32, and the width direction dimension thereof is substantially the same as the width direction dimension of the rear half portion (free end side) of the upper arm portion 21 of the first terminal 20. The same. The upper arm portion 31 has a contact protrusion 31A that is bent so as to protrude downward at an intermediate position in the front-rear direction. When the flat conductor C is inserted, the upper arm portion 31 is subjected to elastic displacement. Thus, the contact protrusion 31A can contact the circuit portion of the flat conductor C. On the other hand, a portion near the front end of the lower arm portion 32 of the second terminal 30 is formed with a held portion that is held by integral molding with the front terminal holding portion 11 of the housing 10.

  The connecting portion 33 of the second terminal 30 is formed to have the same width as the lower arm portion 32 and is located in front of the connecting portion 23 of the first terminal 20. The connection portion 34 of the second terminal 30 extends in a crank shape from the front terminal holding portion 11 toward the front in a state where the second terminal 30 is held by the front terminal holding portion 11 of the housing 10. The connection portion 24 has a lower surface located below the lower surface of the front terminal holding portion 11 of the housing 10 and is connected to the circuit portion of the circuit board by soldering.

  Since the two types of terminals themselves, the first terminal 20 and the second terminal 30 described above, are not the main point of the present invention, further explanation is omitted.

As shown in FIGS. 2, 4, and 5, the movable member 40 has a substantially plate-like main body portion 41 extending in the terminal arrangement direction, and a lower side at both outer positions of the main body portion 41 in FIGS. An end arm portion 42 extending toward the rear in the closed position, a coupling portion 43 coupling the upper ends of the main body portion 41 and the end arm portion 42, and a U-shape extending from the coupling portion 43 to form a terminal arrangement direction An elastic locked arm portion 45 having elasticity in the connector width direction, a locking arm portion 44 extending in a cantilever shape downward from the coupling portion 43 between the main body portion 41 and the end arm portion 42; It has a shaft part 46 that extends outward from the lower part of both end faces of the main body part 41 in the terminal arrangement direction and is connected to the lower end of the end arm part 42. The elastic locked arm 45 is provided with a locked protrusion 45A facing outward in the terminal arrangement direction.

  As shown in FIG. 1, when the movable member 40 is in the closed position, the main body portion 41 covers the entire terminal arrangement range in the terminal arrangement direction, and the upper arms of the first terminal 20 and the second terminal 30 in the front-rear direction. It is formed with dimensions that extend from the rear ends of 21 and 31 to the intermediate positions of the connecting portions 24 and 34 (see also FIG. 6).

  As seen in FIG. 4, the lower end side portion (the rear end side portion in the closed position as seen in FIG. 6A) of the main body 41 projects forward (downward in the closed position). The housing groove 41A for housing the free ends of the upper arms 21 and 31 of the first terminal 20 and the second terminal 30 at positions corresponding to the first terminals 20 and the second terminals 30 in the terminal arrangement direction. It is formed (see FIG. 6A). As described above, the free end portions 21B and 31B of the upper arm portions 21 and 31 are accommodated in the accommodating groove portion 41A, whereby the opposing inner wall surface (a surface perpendicular to the arrangement direction) of the accommodating groove portion 41A Inadvertent displacement of the free ends 21B and 31B of the upper arms 21 and 31 and thus the upper arms 21 and 31 in the arrangement direction is restricted. In the present embodiment, when viewed in the terminal arrangement direction, since the accommodation groove 41A is provided in the vicinity of the region of the shaft portion 46 described later, any of the movable members 40 in the moving range from the closed position to the open position can be used. Also at the position, at least a part of the free end portions 21B, 31B of the upper arm portions 21, 31 is accommodated in the accommodating groove portion 41A, and the region is in the vicinity of the shaft portion 46 (rotation center). Since the movable member 40 does not move so much even when the movable member 40 is opened and closed, the movable member 40 is always in a position including the free end portion, and the displacement of the free end portions 21B and 31B in the terminal arrangement direction can always be regulated. Further, since the accommodating groove 41A is formed in the movable member 40, it is not necessary to provide another member other than the movable member for this restriction, and therefore the connector 1 is not enlarged in the vertical direction.

  As seen in FIG. 4, the main body 41 protrudes forward (downward at the closed position) to the upper end side portion (front end side portion at the closed position seen in FIG. 6A), and It has the wall part 41B extended over a terminal arrangement | sequence range in a terminal arrangement | sequence direction. The wall 41B has a front half (lower half of the front face in the closed position) of the upper surface of the wall 41B, and the recessed portion 41B-1 is formed over almost the entire area in the terminal arrangement direction. The part which is not formed is formed as operation part 41B-2. When the movable member 40 is in the closed position, the movable member 40 is rotated toward the open position by hooking a finger on the operation portion 41B-2.

  As shown in FIGS. 3 and 4, the end arm portion 42 extends downward (rearward in FIG. 1) at both sides of the body portion 41 and has a shaft portion 46 at the lower end thereof. It is connected. Further, the end arm portion 42 is bent in a crank shape when viewed in the terminal arrangement direction, and in FIG. 3 showing the movable member in the closed position, the front half portion is located above the rear half portion.

  As shown in FIG. 4, the locking arm portion 44 is formed with a locking portion 44 </ b> A that protrudes forward (downward in the closed position) at a lower end portion that is a free end. As shown in FIG. 6C, the locking portion 44A protrudes from above into the receiving portion 19A of the housing 10 when the movable member 40 is in the closed position, and the side base 14 Abuts or is close to the top surface of As shown in FIG. 6B, an inclined surface 44A-1 that is inclined downward toward the front is formed on the rear end surface of the locking portion 44A, and the flat conductor C in the insertion process is formed. When the front end portion of the ear portion C2 comes into contact with the inclined surface 44A-1, the locking arm portion 44 is formed as an elastic arm portion that is easily elastically displaced upward by receiving the contact force. The front end surface of the locking portion 44A is formed as a locking surface 44A-2 perpendicular to the front-rear direction, and the locking surface 44A-2 is against the locked portion C2A of the flat conductor C. Thus, the flat conductor C is securely locked to prevent inadvertent extraction of the flat conductor C.

  The locking arm portion 44 is also provided with a regulated portion 47 that protrudes outward from the side surface of the locking portion 44 </ b> A in the terminal arrangement direction at the lower end portion that is a free end. The regulated portion 47 is formed with a range that overlaps a part of the range of the locking portion 44A when viewed in the terminal arrangement direction. In the illustrated example, the regulated portion 47 is provided in a region including a bent portion where the lower surface of the elastic arm portion (lower surface in FIG. 4) and the upper surface (front edge) of the locking portion 44A intersect in FIG. ing. By doing so, the stepped corner that becomes the boundary between the bent portion where the locking portion 44A protrudes from the locking arm portion 44 and the restricted portion 47 between the locking arm portion 44 and the locking portion 44A. The locking arm portion 44, the locking portion 44A, and the restricted portion 47 are integrally provided to reinforce each other, and the strength is improved. When the movable member 40 is in the closed position, the regulated portion 47 enters the concave regulating portion 17C formed in the side regulating portion 17 of the housing, and the vertical side edge 17C of the regulating portion 17C. -1 faces in the front-rear direction, and is in a positional relationship to be regulated from the regulating portion 17C in this direction.

  As shown in FIGS. 3 (B) and 6 (C), the regulated portion 47 is a cross-sectional perspective view with the outer portion removed from the regulated portion 47 at one end side in the connector width direction. It is provided in a size and position that can be accommodated in the restriction portion 17C having a shape, extends in the vertical direction at the front and rear edges, is parallel to each other, and faces the vertical side edge 17C-1 of the restriction portion 17C with a gap in the front-rear direction. Thus, it has a polygonal cross-sectional shape having two regulated edges 47A and 47B at positions where the regulation can be performed. The oblique edges 47C and 47D adjacent to the regulated edges 47A and 47B are formed as oblique edges in order to smoothly enter and exit the restricting portion 17C.

  Further, the movable member 40 is provided with the previously-described elastic locked arm portion 45 extending from the coupling portion 43, and the elastic locked arm portion 45 can be seen in FIG. 5 showing the movable member 40 in the open position. 5 has a U-shape having a U-shaped bottom portion at the front and a U-shaped opening portion at the rear, has elasticity in the connector width direction, and has a locked projection 45A on the rear end side. Is formed. The upper surface of the elastic locked arm portion 45 is on the same level surface as the upper surface of the coupling portion 43. When the movable member 40 is in the closed position, the locked projection 45A is positioned below the lock portion 15B of the housing 10 so that it can be locked with the lock portion 15B, so that the movable member 40 is inadvertently opened. It is prevented from turning to. In the present embodiment, the locked protrusion 45A is provided at both ends of the movable member 40 in the connector width direction. However, the position of the locked protrusion is not limited to this, and the lock protrusion 15B of the housing 10 It can be anywhere as long as it works together.

  The shaft portion 46 is located on one axis extending in the arrangement direction and has a cylindrical shape extending outward and inward from the end arm portion 42, and is formed as an outer supported portion 46A and an inner supported portion 46B, respectively. ing. The outer supported portion 46A is cut off so that a part thereof becomes a slope 46A-1 from the base toward the tip, and the tip surface is a semicircle. The inner supported portion 46B remains in a cylindrical shape.

  As described above, since the end arm portion 42 is accommodated in the end arm accommodating portion 19B-2 formed as a space located between the side wall 15 and the side restricting portion 17, the outer supported portion 46A is It is accommodated in the support hole 15A of the side wall 15, and is supported rotatably by the support hole 15A. On the other hand, the inner supported portion 46B is accommodated in the support concave portion 17B of the side regulating portion 17, and is supported rotatably by the support concave portion 17B.

  The movable member 40 having such a configuration is attached in the following manner. First, the movable member 40 is caused to enter between the two side walls 15 of the housing 10 from above. At this time, in the posture as shown in FIG. 5, the inclined surface 46A-1 is formed on the outer supported portion 46A of the shaft portion 46 of the movable member 40 and the inclined surface 46A-1 is positioned on the lower side. The two side walls 15 are pushed apart in the axial direction. Then, with the fulcrum part 10C-1 as a fulcrum, the outer supported part 46A of the shaft part 46 is moved to the housing 10 while the outer part of the side frame part 10C of the housing 10 is elastically displaced outward in the terminal arrangement direction. The inner supported portion 46B of the shaft portion 46 is advanced from above into the support concave portion 17B of the side regulating portion 17 of the housing 10. The movable member 40 is attached to the housing 10 by returning the outer portion to the free state.

  As shown in FIGS. 1 and 2A, 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 connected to the main body housing portion 19B (FIG. A) and (B)) and the end arm portion 42 of the movable member 40 is accommodated in the end arm accommodating portion 19B-2 of the housing 10 (see FIGS. 3A and 3B). The As shown in FIG. 1, the movable member 40 is almost entirely accommodated in the accommodation portion 19 </ b> B in the up-down direction at the closed position, and the vertical dimension of the connector 1 can be reduced accordingly. (See also FIG. 6 (A), FIG. 7 (A), and FIG. 8 (A)). Further, in the closed position, the movable member 40 covers the terminal arrangement range, thereby preventing dust and dirt from adhering to the first terminal 20 and the second terminal 30. In the present embodiment, almost all of the movable member 40 in the vertical direction is accommodated in the accommodating portion 19B. Instead, a part of the movable member in the vertical direction is accommodated in the accommodating portion. However, it is possible to reduce the vertical dimension of the connector 1 by the accommodated dimension.

  The fixing bracket 50 is held by the side base portion 14 of the housing 10 at positions near both ends of the housing 10 in the terminal arrangement direction and at the rear end side in the front-rear direction. The fixing metal fitting 50 is made by bending a band-shaped metal plate whose width direction is the terminal arrangement direction in the plate thickness direction, and corresponds to a held portion (not shown) held in the housing 10 and a circuit board. And a fixing part 51 to be soldered to the part. The held portion is integrally molded with the side base portion 14 of the housing 10 and is held by the side base portion 14. The fixing bracket 50 extends rearward, and its lower surface is located below the lower surface of the side base portion 14 and is soldered to a corresponding portion of the circuit board. This solder connection contributes to fixing the connector 1 to the circuit board.

  Next, the connection operation between the connector 1 and the flat conductor C will be described with reference to FIGS. 6 to 9 are cross-sectional views of the connector 1 taken along a plane perpendicular to the arrangement direction. The flat conductor C is inserted before, the flat conductor C is inserted, and the flat conductor C is inserted. A state in which the mold conductor is drawn in the extraction direction and a state immediately before the flat conductor C is extracted are shown. 6 to 9, (A) is the position of the first terminal 20, (B) is the position of the locking arm portion 44 of the movable member, and (C) is the locking arm portion 44 of the movable member 40. The cross section in the position of the to-be-regulated part 47 extended from is shown.

  First, the connection portions 24 and 34 of the first terminal 20 and the second terminal 30 of the connector 1 are solder-connected to the corresponding circuit portion of the circuit board, and the fixing portion 51 of the fixing bracket is solder-connected to the corresponding portion of the circuit board. Since the outer portion of the side frame portion 10C of the housing 10 is fixed to the circuit board by the solder connection of the fixing portion 51, the elastic displacement of the outer portion with the fulcrum portion 10C-1 as a fulcrum is restricted. As a result, the movable member 40 is prevented from being detached from the housing 10.

  Next, as shown in FIGS. 6A to 6C, the movable member 40 is brought to the closed position, and the flat conductor C is extended in the front-rear direction along the surface of the circuit board behind the connector 1. To be located. Next, the flat conductor C is inserted into the receiving portion 19A of the connector 1 facing forward. At the time of this insertion, the flat conductor C is guided toward the receiving portion 19A by the guide surface 14B and the guide surface 16A formed on the housing 10. Further, the flat conductor C inserted into the receiving portion 19A is positioned in the width direction by the side regulating surface 17A (see FIGS. 3A and 3B) of the side regulating portion 17 of the housing 10. Further, the flat conductor C is positioned in the front-rear direction by the front restricting surface 18 </ b> A of the front restricting portion 18 of the housing 10. Therefore, in this embodiment, the flat conductor C can be easily brought to a predetermined regular position simply by inserting the flat conductor C into the receiving portion 19A.

  In the process of inserting the flat conductor C into the receiving portion 19A, the flat conductor C enters the lateral U-shaped portion of the first terminal 20 and elastically displaces the lateral U-shaped portion. Specifically, the front end of the flat conductor C abuts on the contact protrusion 21A of the upper arm portion 21 of the first terminal 20 and pushes up the contact protrusion 21A by the vertical component of the contact force. By abutting on the support protrusion 22A of the lower arm part 22 of the terminal 20 and pushing down the support protrusion 22A, the upper arm part 21 is elastically displaced upward and the lower arm part 22 downward, and the upper arm part 21 And the lower arm portion 22 are pushed forward to advance. As a result, as shown in FIG. 7A, in the state where the insertion of the flat conductor C is completed, the flat conductor C has the contact protrusion 21A of the upper arm portion 21 and the support protrusion of the lower arm portion 22. A circuit portion (not shown) that is sandwiched between 22A and exposed on the upper surface of the flat conductor C and the contact protrusion 21A of the upper arm portion 21 come into contact with each other with contact pressure.

  In the present embodiment, the contact protrusion 21A of the upper arm portion 21 is located behind the support protrusion 22A of the lower arm portion 22, and contacts from the base portion of the upper arm portion 21 (portion connected to the connecting portion 23). The length to the protruding portion 21A is larger than the length from the base of the lower arm portion to the supporting protruding portion 22A, and elastic bending is likely to occur. Accordingly, in the state where the flat conductor C is inserted between the upper arm portion 21 and the lower arm portion 22, the upper arm portion 21 has a larger elastic displacement than the lower arm portion.

  Further, in the process of inserting the flat conductor C into the receiving portion 19A, the front end of the flat conductor C abuts on the contact protrusion 31A of the upper arm portion 31 of the second terminal 30, and the vertical force component of the abutment force. By pushing up the contact protrusion 31A, the upper arm 31 is elastically displaced upward. As a result, as shown in FIG. 7A, in a state where the insertion of the flat conductor C is completed, a contact protrusion between the circuit portion (not shown) exposed on the upper surface of the flat conductor C and the upper arm portion 31. 31A contacts with contact pressure.

  Further, in the process of inserting the flat conductor C into the receiving portion 19 </ b> A, the locking portion formed at the rear end of the locking arm portion 44 of the movable member 40 is an ear portion C <b> 2 positioned near both ends of the flat conductor C. Abutting on the inclined surface 44A-1 of 44A, the engaging arm portion 44 is elastically displaced upward by a vertical component of the abutting force to bring the flat conductor C into a position allowing insertion. When the flat conductor C is further inserted and the ear portion C2 passes through the position of the locking portion 44A, the locking arm portion 44 is displaced downward so as to reduce the amount of elastic displacement and returns to the free state. It rushes into the notch C1 of the conductor C. As a result, as shown in FIG. 7B, in the state where the insertion of the flat conductor C is completed, the locked portion C2A of the flat conductor C is in contact with the locking surface 44A-2 of the locking portion 44A. Therefore, the flat conductor C is prevented from being pulled out rearward. In addition, it is not essential that the locking arm part 44 returns to a completely free state. For example, with the locking arm 44 leaving a slight amount of elastic displacement, the locking portion 44A enters the notch C1 of the flat conductor C and is positioned to be locked with the locked portion C2A. It is also possible to adopt a configuration in which the ear portion C2 of the flat conductor C is sandwiched between the locking arm portion 44 and the side base portion 14 in the vertical direction.

  Next, when the flat conductor C in the state of FIGS. 7A to 7C is subjected to an excessive rearward force before the flat conductor C is unintentionally extracted, the flat conductor Since C strongly pulls the locking portion 44A provided on the locking arm portion 44 of the movable member 40 to the rear, the movable member 40 itself may shift backward as shown in FIGS. And However, the movable member 40 can be seen in FIG. 8C even if the regulated portion 47 protruding laterally from the locking arm portion 44 is in the concave regulating portion 17C of the housing and is displaced rearward. As described above, the regulated edge 47B on the rear side of the regulated part 47 abuts on the vertical side edge 17C-1 on the rear side of the regulated part 17C, and further movement is prevented. Therefore, the situation of the detachment | moving of the movable member 40 and the damage of 44 A of latching parts does not arise. The deviation is a maximum value of the backlash between the movable member and the housing.

  When the flat conductor C in the state shown in FIGS. 7A to 7C, that is, in the connection state with the connector 1 is intentionally extracted from the connector 1, the movable member 40 in the closed position is rotated. To the open position shown in FIGS. 9 (A)-(C). As shown in FIG. 9C, when the movable member 40 is in the open position, the locking portion 44A of the rotated locking arm portion 44 is positioned away from the cutout portion C1 of the flat conductor C. The regulated portion 47 is located above the regulating portion 17C. That is, the latching state of the latching portion 44A with respect to the latched portion C2A of the flat conductor C and the regulation state of the regulation portion 17C with respect to the regulated portion 47 are released, and the flat conductor C is pulled out rearward. Permissible. In this state, when the flat conductor C is pulled backward, the flat conductor C can be easily extracted.

  In the present invention, the regulated portion 47 provided on the locking arm portion 44 is not limited to the form of entering the concave regulating portion 17C of the housing downward when the movable member 40 comes to the closed position, and the lower side and the side. It is also possible to enter with a movement toward the direction.

  As shown in FIG. 10, the locking portion 44 </ b> A of the locking arm portion 44 is formed as an inclined surface from the side inward to the front, and the front end of the locking portion 44 </ b> A is made to coincide with the front end of the restricted portion 47. When the conductor C is in the normal insertion position, the restricted portion 47 is positioned to the side of the restricting portion 17 of the housing (see FIG. 11A). When the locked portion C2A that is the rear end edge of the ear portion C2 formed by the cutout portion C1 of the flat conductor C is set as a slanted edge that matches the locking portion 44A, the flat conductor C is in the normal position, As shown in FIG. 11A, the locked portion C2A and the locking portion 44A have a positional relationship. When the flat conductor C is strongly pulled backward, the restricted portion 47 is locked to the locking portion of the flat conductor C. 44A is a cam function in which 44A receives a force rearward from the latched portion C2 of the flat conductor C, and the latching arm portion 44 bends to the side by the force of the side component and the regulated portion 47 is displaced in the same direction. And enters the restricting portion 17C as shown in FIG. Subsequent restriction of the restricted portion 47 by the restricting portion 17C is the same as in the previous example. As for the relationship between the locking portion 44A and the locked portion C2A, it is sufficient that at least one of them has a cam function on a slope relative to the other even if both are not slopes.

  Further, in order to increase the restriction force by the restriction portion 17C and the restricted portion 47 without impairing the insertability, the amount of engagement of the restricted portion 47 may be increased as compared with the engagement portion 44A. As described above, the restricting portion 17C is formed as a hole or groove that penetrates to the bottom of the housing without forming a recess, and the height of the restricted portion 47 can be increased without changing the height of the locking portion 44A. It is possible, and by doing so, the height of the restriction contact surface is increased, and the restriction force is increased accordingly.

  In the present invention, the restricting portion is not limited to the case where it is formed on the housing as shown in the embodiment, and may be formed on a member attached to the housing, for example, a fixed bracket, or the movable member may be It is good also as forming in the position which can contact | abut to a to-be-controlled part when it exists in a closed position. Further, the displacement direction of the regulated portion to the regulated position relative to the regulating portion may be downward.

In the present invention, the locking arm portion provided on the movable member, as in the illustrated embodiment, without being limited to it extends rearward, if extending laterally to a width direction of the connector good. In short, when the locking arm portion is formed as an elastic arm portion and the movable member is in the closed position, the locking portion provided at the tip of the locking arm portion is locked to the flat conductor. It suffices if it comes to a position to be locked with the part.

  Furthermore, the movable member does not need to have a plate shape that covers the receiving portion of the housing. In the illustrated embodiment, the housing is not provided with an upper wall that covers the terminal arrangement area (front and rear and width direction range) as shown in FIG. 3A, and the receiving portion is fully opened upward. However, if the housing is provided with an upper wall portion that covers this terminal arrangement area, the movable member is no longer required to have a function of covering the receiving portion. It is also possible to form the upper wall portion as a U-shaped frame body that wraps in three directions.
