In this way, since the upper surface top held portion 23A is wider than the contact portion 21A, the holding force of the terminal 20 by the housing 10 can be increased. Moreover, since the contact part 21A is narrow in width, the elastic displacement in the contact part 21A becomes easy.

The movable member 30, as shown in Figs. 2(A) and (B) showing the movable member 30 in the same posture as the open position, the connector width direction (Y-axis direction) and the vertical direction ( Z-axis direction) and a substantially plate-shaped body portion 31, which is lower than the body portion 31 (Z2 side) and extends from the front side (X1 side) in the connector width direction, and includes a rotation axis Has a base (35). In the present embodiment, the movable member 30 rotates between the open position and the closed position around the rotation axis, but instead of this, the movable member is, for example, the axis direction along with the rotation around the rotation axis line. The slide movement or the like may be performed in a plane at right angles.

The body portion 31 extends over the terminal arrangement range in the connector width direction, as shown in Figs. 2(A) and (B), and closes the terminal 20 in the closed position (refer to Fig. 11(A)). A cover plate portion 32 covering from above, an end wall portion 33 located outside the cover plate portion 32 in the connector width direction and extending in the vertical direction, and the end wall portion 33 at the open position It has an end plate portion 34 (see also Fig. 1(A)) as an extension portion extending outward from the lower portion of the connector in the width direction and accommodated in the receiving hole portion 15A of the housing 10.

The end wall portion 33, as shown in Figs. 2 (A) and (B), is located in front of the cover plate portion 32 (below in the closed position) with the movable member 30 in the open position. , It extends in the vertical direction. As shown in Fig. 2B, at the lower end of the end wall portion 33, a locking portion 33A protruding toward the front is formed. When the upper surface of the locking portion 33A forms a locking surface 33A-1 that is inclined upward as it faces forward (see also Fig. 9(B)), and the movable member 30 is in the closed position That is, in a state in which the locking surface 33A-1 is inclined forward as it faces downward, the locking surface 33A-1 can be locked from the rear with respect to the engaging portion F2A of the flat conductor F. It is supposed to be done (see Fig. 11(B)).

As shown in Figs. 2 (A) and (B), the end plate portion 34 has a substantially sector shape that is convexly curved upward and forward as viewed in the connector width direction (Fig. 8(A), ( B) see also). The end plate portion 34 is accommodated in the accommodation hole portion 15A of the housing 10, as shown in Fig. 1, and the convex curved surface of the end plate portion 34 is the movable member 30 When rotating between the open position and the closed position, the front inner wall surface of the receiving hole portion 15A, that is, the rear surface of the front side wall 15B can be guided in the rotation direction by sliding contact.

Further, the end plate portion 34 has a shape in which the lower portion in the open position has a notched rear surface thereof, and is formed as a regulated portion 34A. The rear surface of the regulated portion 34A when the movable member 30 is in the open position (flat surface perpendicular to the front-rear direction) is regulated by the regulation portion 15C-2 of the housing 10 in the closed position. It forms the surface 15C-2A and the regulated surface 34A-1 which can be engaged. Specifically, when the movable member 30 is brought to the closed position, as shown in Fig. 11(C), the regulated portion 34A is a rear recessed portion of the side wall 15 of the housing 10 ( 15C-1), and is positioned below the regulating portion 15C-2 of the housing 10. And the regulated surface 34A-1 (upper surface in the closed position) of the regulated portion 34A has a gap in the vertical direction with respect to the regulation surface 15C-2A of the regulation portion 15C-2 Face to face, and it becomes a state in which it can be locked. As a result, even if an external force for further rotating the movable member 30 rotated to the closed position or an external force for lifting the movable member 30 upward is received, the regulated surface 34A-1 becomes the regulating surface ( The rotation and movement of the movable member 30 are restricted by engaging 15C-2A) from below.

The rotating base 35 is, as shown in FIG. 2(B), the first shaft portion 35A extending in a range including the terminal array range, and the outer side in the terminal arrangement direction from both end surfaces from the end plate portion 34 It has a 2nd shaft part 35B as a prismatic rotational shaft part extending toward the direction, and a plurality of engagement parts 35C which couples the 1st shaft part 35A to the body part 31.

The first shaft portion 35A has a cross section perpendicular to the connector width direction when the movable member 30 is in the open position, as shown in Figs. 6(A) and (B), extending in the front-rear direction. It has a square shape. The first shaft portion 35A extends to a range including the terminal arrangement range as described above, and connects the inner side surfaces of the end wall portions 33 (the side surfaces located inward in the connector width direction). (See Fig. 2(B)). In the first shaft portion 35A, even when the movable member 30 is at an angular position in the rotation direction, the portion positioned corresponding to the first bracket 40 in the connector width direction is the first bracket 40 ) Is positioned immediately below the first width narrow arm portion 41B as a blocking portion, and functions as a blocked portion that is prevented from moving upward by the first width narrow arm portion 41B (FIGS. 9 to 11 See also). In short, in this embodiment, since the blocking portion and the inhibited portion are distributed and present within the terminal arrangement range, the size of the connector 1 in the connector width direction is not increased, and it is movable in a wide range in the connector width direction. Blocking of the movement of the member 30 to the upper side is attempted.

As shown in Figs. 2(A) and (B), the second shaft portion 35B has a rectangular shape extending in the vertical direction as viewed in the connector width direction when the movable member 30 is in the open position. have. The 2nd shaft part 35B is accommodated in the accommodation hole part 15A of the housing 10 together with the end plate part 34 mentioned above (refer FIG. 1). The second shaft portion 35B is positioned directly above the second narrow arm portion 51B as a blocking portion of the second bracket 50 even when the movable member 30 is at an angle position in the rotation direction thereof, The second narrow arm portion 51B functions as a restrained portion in which downward movement is prevented (see Figs. 7A and 7B).

The engaging portion 35C is positioned correspondingly between the two first brackets 40 adjacent to each other, and as shown in Fig. 2(B), in a state in which the movable member 30 is in the open position, the rear portion It has a width narrowing engaging portion 35C-1 which is formed and coupled to the lower end of the main body 31, and a width narrowing engaging portion 35C-2 that is formed in the first half and is coupled to the upper surface of the first shaft portion 35A. As shown in Figs. 4(A) and (B), the width narrow coupling portion 35C-2 has a larger dimension in the connector width direction than the width narrow coupling portion 35C-1, and the width narrow coupling portion 35C The boundary position between -1) and the light width coupling part 35C-2 forms a single phase.

As shown in Fig. 2(B), between the two engaging portions 35C adjacent to each other, the entry allowing the entry of the first bracket 40 from the front of the first narrow arm portion 41B to be described later The allowable portion 36 is formed to penetrate in the front-rear direction (see also Fig. 4(B)). The entry allowable portion 36 is positioned between the width narrow coupling portions 35C-1 in the state where the movable member 30 is in the open position, as shown in FIG. 4(B), and the first width narrower It is positioned between the rear end receiving portion 36A for accommodating the rear end of the arm 41B and the wide light engaging portion 35C-2, and is narrower than the rear end receiving portion 36A, and is inserted through the first width narrowing arm 41B It has an insertion passage allowable part 36B which allows (see also FIG. 6(A)). In addition, as shown in Fig. 6(A), in the state in which the movable member 30 is in the open position, the rear end accommodating portion 36A forms a hole shape through which the first half penetrates in the vertical direction, and the second half Forms a groove shape opened downward, and the insertion passage allowable portion 36B constitutes a groove shape opened upward.

As shown in Figs. 3(A) and 3(B), the first bracket 40 is bent in the plate thickness direction by a band-shaped metal plate member whose dimensions in the connector width direction (Y-axis direction) are the terminal width direction. It is made by doing so, and has a substantially crank shape as a whole (see also Fig. 6(A)). In this embodiment, the 1st bracket 40 is formed more than the 2nd bracket 50 which forms the same line with the 1st bracket. The first bracket 40 is, as shown in Fig. 3(B), an upper arm part 41 extending in an anteroposterior direction (X-axis direction), and a connection part extending forward from a position below the upper arm part 41 A first fixing portion 42 as a first connection portion 43 connecting the front end of the upper arm portion 41 and the rear end of the first fixing portion 42, and the front end of the upper arm portion 41 and the first connecting portion 43 It has an upper bent part 44 bent at the boundary position of the upper end of the, and a lower bent part 45 bent at a boundary position of the rear end of the first fixing part 42 and the lower end of the first connecting part 43. The first bracket 40 has a maximum terminal width dimension (dimension in the Y-axis direction) in the first wide arm portion 41A and the first connection portion 43 to be described later of the upper arm portion 41 .

As shown in FIG. 4(A), the upper arm part 41 is the 1st widening arm part 41A (FIG. 6 (FIG. 6)) which is embedded and held by the front frame part 10A of the housing 10 by integral mold molding. A) also see FIG.), and the 1st width narrow arm part 41B as a blocking part extending rearward from the 1st width|variety arm part 41A. The rear end of the first narrow arm portion 41B is not held by the housing 10, and therefore, the upper arm portion 41 has a cantilever compensation.

The first wide arm portion 41A has its rear end extending rearward from the rear surface of the front frame portion 10A, and the rear end portion of the first wide arm portion 41A and the first width narrow arm portion 41B are , It is accommodated in the accommodation recessed part 17B of the housing 10 (refer FIG. 6(A) also). The terminal width dimension (dimension in the connector width direction) of the first narrow arm portion 41B is, as shown in Fig. 4A, in the connector width direction, one ground terminal 20G and its ground terminal It has a dimension including three terminals 20 in total of the signal terminals 20S arranged one by one on both sides of the 20G.

In this way, by setting the terminal width dimension of the first bracket 40 in correspondence with the three terminals 20 consisting of one ground terminal 20G and two signal terminals 20S, one in the connector width direction In a state where the three terminals 20 are positioned within the range of the first bracket 40, the combination of the first bracket 40 and the three terminals 20 is repeatedly arranged in the connector width direction, The arrangement of the terminals 20 and the first bracket 40 for transmission of a high-speed differential signal can be easily formed.

As shown in Fig. 4(A) and (B), the first narrow arm portion 41B is narrower in the connector width direction than the first wide arm portion 41A, and at the rear end (free end) Protrusions 41B-1 protruding to both sides in the connector width direction are formed. The first narrow arm portion 41B has a portion extending forward and rearward than the first shaft portion 35A of the movable member 30 in the front-rear direction, as shown in Figs. 6(A) and (B). It has, and the rolled surface of that part is exposed.

The first narrow arm portion 41B is positioned above the first shaft portion 35A of the movable member 30, even if the movable member 30 is at any angular position in the rotation direction, and the first shaft portion 35A ) In a state in contact with the first shaft portion 35A and further, the movement of the movable member 30 upward is prevented, and the movable member 30 from the housing 10 is prevented from being pulled upward ( 6(A) and 11(A)). In addition, in this embodiment, even when the movable member 30 is in the open position (refer to Fig. 6(A)) and in the closed position (refer to Fig. 11(A)), the first width narrow arm part 41B is The lower surface is in contact with the upper surface of the first shaft portion 35A.

In the present embodiment, the first width narrow arm portion 41B is supposed to be positioned in contact with the first shaft portion 35A, but instead of this, it may be positioned with a slight gap in the vertical direction with respect to the first shaft portion 35A. . In this case, the first narrow arm portion 41B prevents the upward movement of the first shaft portion 35A by a predetermined amount or more corresponding to the dimension of the gap.

The first narrow arm portion 41B enters the entry allowable portion 36 of the movable member 30 from the front. Specifically, the first narrow arm portion 41B passes through the insertion passage allowable portion 36B of the entry allowable portion 36, and the rear end of the first narrow arm portion 41B is the insertion passage allowance portion ( It reaches the outside of 36B) and is located in the rear end accommodating part 36A. As shown in Fig. 4(B), the protrusion 41B-1 formed at the rear end of the first narrow arm portion 41B is, in the rear end accommodating portion 36A, the rotation base of the movable member 30 ( It is positioned so as to be able to engage with the rear surface of the light width engaging portion 35C-2 formed in 35), and as a result, the movable member 30 from the housing 10 is prevented from being removed from the rear surface.

The first narrow arm portion 41B is formed at the same position as the ground terminal 20G in the connector width direction, as shown in Fig. 4B, and is located on both sides of the ground terminal 20G. It is located between the signal terminals 20S. Moreover, as shown in FIG. 4(B), the 1st narrow arm part 41B is located in the front-rear direction, and the rear end part of the 1st narrow arm part 41B overlaps with the ground terminal 20G. . Accordingly, the rear end of the first narrow arm portion 41B is positioned opposite to the contact portion 21A of the ground terminal 20G in the vertical direction when viewed in the connector width direction, as shown in Fig. 6A. .

The rear end portion of the first fixing portion 42 of the first bracket 40 and the first connecting portion 43 are attached to the front frame portion 10A of the housing 10, as shown in Fig. 6(A). As a result, it is embedded and held by integral mold molding (see also Fig. 8(A)). In this embodiment, as shown in Fig. 3(B), the bending angles at each of the upper bent portion 44 and the lower bent portion 45 of the first bracket 40 (bending with respect to the mounting surface of the circuit board) The angle of) is equal, and is almost a right angle (shown as "theta1" as the bending angle in FIG. 3(B)).

The first fixing portion 42 of the first bracket 40 has a front end portion extending forward from the front frame portion 10A of the housing 10 (Fig. 2(B) and Fig. 6(A)). )), the first fixing pad (not shown), which is a corresponding part of the circuit board B, is solder-connected and fixed on the lower surface thereof.

In the present embodiment, the first fixing portion 42 is formed at the same position as the ground terminal 20G and the ground connecting portion 22G of the ground terminal 20G in the connector width direction, and the ground terminal 20G ) Between the signal terminals 20S positioned on both sides of the) and further between the signal connection portions 22S of the signal terminals 20S. In other words, the signal connection portion 22S of the signal terminal 20S is located between the first fixing portions 42 of the first bracket 40 adjacent to each other in the connector width direction.

In this embodiment, as described above, since the signal connection portion 22S is positioned between the first fixing portions 42, a signal pad for soldering the signal connection portion on the mounting surface of the circuit board B (shown Omitted), even if the signal conductive pattern (not shown) is formed by extending in a straight line forward, the signal conductive pattern interferes with the first fixing pad (not shown) for solder connection of the first fixing part 42. Instead, it can be formed by extending further forward through the adjacent first fixing pads.

Moreover, in this embodiment, the ground connection part 22G of the ground terminal 20G is located in the same position with respect to the said 1st fixing part 42 in the connector width direction. Therefore, the ground conductive pattern (not shown) connected to the ground pad (not shown) is from the ground pad (not shown) for solder connection of the ground connection portion 22G on the mounting surface of the circuit board B. When formed to extend in a straight line toward the front, the ground conductive pattern (not shown) interferes with the first fixing pad and is connected, but even if the ground conductive pattern and the fixing pad are connected, the ground characteristics have no effect. Not crazy In addition, in the present embodiment, it is assumed that the ground connection portion 22G is located at the same position with respect to the first fixing portion 42 in the connector width direction, but even if it is not the same position, the ground connection portion 22G is positioned in the connector width direction. In the above, it is sufficient to have an overlapping range with respect to the first fixing portion 42 and be positioned.

Therefore, in order to smoothly implement the connector 1 according to the present embodiment having the first bracket 40 in front of the terminal 20, the flat conductor is inserted and extracted from the connector 1, the circuit board ( It can be mounted near the rear edge of B).

The second bracket 50 is formed at the same position as the accommodation hole 15A of the housing 10 and the second shaft 35B of the movable member 30 in the connector width direction. As shown in FIG. 3(A), the 2nd bracket 50 is made by bending a metal plate member of the same shape as that used for making the 1st bracket 40 in the plate thickness direction. As described later, in the second bracket 50, the angle to be bent is smaller than the right angle, and the second connecting portion 53 to be described later is inclined more gently than the first connecting portion 43 of the first bracket 40. It differs from the first bracket 40 only in, and the other configuration is the same as that of the first bracket 40. With respect to the second bracket 50, a sign obtained by adding "10" to the sign in the first bracket 40 is attached to the portion corresponding to the first bracket 40, and detailed description thereof is omitted.

The second bracket 50 includes a lower arm portion 51 extending in the anteroposterior direction (X-axis direction), a second fixing portion 52 as a connection portion extending forward from a position lower than the lower arm portion 51, It has a 2nd connection part 53 which connects the front end of the lower arm part 51 and the rear end of the 2nd fixing part 52. As shown in Fig. 3(C), the bending angle with respect to the mounting surface of the circuit board in each of the upper bent portion 54 and the lower bent portion 55 of the second bracket 50 is equal and smaller than the right angle. (In Fig. 3(C), the bending angle is shown as "θ2"). In short, the bending angle θ2 in the second bracket 50 is smaller than the bending angle θ1 in the first bracket 40.

Although the 2nd bracket 50 has a substantially crank shape as a whole, since the angle at which the metal plate member is bent (the bending angle θ2 described above) is smaller than a right angle, Figs. 3(C) and 7(A) As shown in, (B), the second connecting portion 53 is inclined downward as it faces forward. Therefore, in the posture that the second bracket 50 is held in the housing 10, that is, the posture in which the dimension in the connector width direction (Y-axis direction) is the terminal width direction, the lower arm 51 of the second bracket 50 ) Is located below the upper arm part 41 of the first bracket 40.

The lower arm portion 51 is, as shown in Fig. 3(A), a second wide arm of the same shape as the first width arm portion 41A and the first width narrow arm portion 41B of the first bracket 40. It has an arm part 51A and a 2nd width narrow arm part 51B. The lower arm portion 51 is a range including the accommodation hole portion 15A of the housing 10 in the front-rear direction at an intermediate position in the vertical direction of the housing 10, as shown in FIG. 7(A) Extends over, and the front end portion of the second wide arm portion 51A and the rear end portion of the second width narrow arm portion 51B are held by integral mold molding by the side wall 15 of the housing 10 have. The lower arm portion 51 has portions extending forward and rearward from the second shaft portion 35B of the movable member 30, and the rolled surface of the portion is exposed. In this embodiment, since the protrusion 51B-1 (refer to Fig. 3A) is formed at the rear end of the second narrow arm 51B, the protrusion 51B-1 is integrally molded to form the side wall 15 ) By being buried in the lower arm portion 51 is held firmly.

As shown in Fig. 7A, the lower arm 51 has an intermediate portion positioned in the accommodation hole 15A in the front-rear direction exposed. This exposed portion forms a blocking portion for preventing the movement of the second shaft portion 35B of the movable member 30 from moving downward. The lower arm portion 51 is located under the second shaft portion 35B of the movable member 30, even if the movable member 30 is at any angular position, and the second shaft portion 35B furthermore the movable member 30 ) Downward movement is regulated, and lowering of the movable member 30 from the housing 10 is prevented. In addition, in this embodiment, even when the movable member 30 is in the open position (refer to Fig. 7(A)) and in the closed position, the upper surface of the lower arm 51 is on the lower surface of the second shaft 35B. We are facing.

In this embodiment, the lower arm portion 51 is positioned in contact with the second shaft portion 35B, but instead of this, it may be positioned with a slight gap in the vertical direction with respect to the second shaft portion 35B. In this case, the lower arm portion 51 prevents the downward movement of the second shaft portion 35B by a predetermined amount or more corresponding to the size of the gap.

In the present embodiment, the lower arm portion 51 of the second bracket 50 is at the front end portion of the second wide arm portion 51A and the rear end portion of the second narrow arm portion 51B, as described above. As it is held in the housing 10, it is held in the housing 10 at a position close to both ends of the lower arm 51 in the longitudinal direction. In short, since the lower arm part 51 is held by the double arm compensation, when the movement of the second shaft part 35B of the movable member 30 is prevented by the lower arm part 51, the second shaft part 35B is It has sufficient strength against abutting force and can counteract.

As shown in Fig. 7(A), the rear end portion of the second fixing portion 52 of the second bracket 50 and the second connecting portion 53 are formed by the front side wall 15B of the housing 10. It is kept buried by integral mold molding. The second fixing portion 52 has a front end portion extending forward from the front side wall 15B (refer to Fig. 2(B)), and a second fixing part which is a corresponding part of the circuit board B from its lower surface. The pad (not shown) is connected by solder and fixed.

The third bracket 60 is formed behind the second bracket 50 at a position corresponding to the side wall 15 of the housing 10 in the width direction of the connector, and is formed in the rear portion of each side wall 15. The third bracket 60 is kept arranged in the connector width direction. As shown in Fig. 3A, the third bracket 60 is formed by bending a strip-shaped metal plate member whose dimensions in the connector width direction (Y-axis direction) are the terminal width direction in the plate thickness direction. The third bracket 60 has a shape in which most of the contact arm portion 21 of the terminal 20 described above (the portion excluding the rear end portion of the contact arm portion 21) is cut off. That is, the third bracket 60 includes a front end 61 formed with a lighter width than that of the other portion, a third fixing portion 62 as a connecting portion extending rearward from a position below the front end 61, and a front end ( 61) and the third connecting portion 63 connecting the front end of the third fixing portion 62, and the upper bent portion bent at the boundary position between the rear end of the front end 61 and the upper end of the third connecting portion 63 ( 64) and a lower bent portion 65 bent at a boundary position between the front end of the third fixing portion 62 and the lower end of the third connecting portion 63. The front end portion 61 and the third connection portion 63 are embedded and held by integral mold molding by the rear side wall 15C of the housing 10, as shown in FIG. 9(C). The third fixing portion 62 extends rearward from the rear side wall 15C of the housing 10, and is connected by solder to a third fixing pad (not shown) that is a corresponding portion of the circuit board B on the lower surface thereof. It is supposed to be fixed.

The connector 1 having the above configuration is manufactured in the following manner.

As described above, in the present embodiment, a curved fine piece 120 is formed from a fine piece of the same shape formed on the small piece 101 with a carrier, and a part of the remaining portion of the curved piece 120 is excised. By forming the bent fine piece 160, the terminal 20 can be easily made from the bent fine piece 120 and the third bracket 60 from the bent fine piece 160. As a result, the efficiency of the manufacturing operation of the terminal 20 and the third bracket 60 and furthermore the connector 1 is improved.

In addition, some of the finely divided pieces of the plurality of finely divided pieces of the small piece 102 to which the carrier is attached are bent in the plate thickness direction to form the curved fine piece 140 forming the shape of the first bracket 40. , The remaining finely divided pieces are bent in the plate thickness direction to form the curved finely divided pieces 150 forming the shape of the second bracket 50 (see Fig. 5). At this time, the curved fine piece 140 is formed by bending the part of the small piece under a bending angle θ1 (refer to FIG. 3(B)), and the curved fine piece 150 is a bending angle of the remaining small piece It is formed by bending under (θ2) (see Fig. 3(C)).

As a result, the efficiency of the manufacturing operation of the first bracket 40 and the second bracket 50 and furthermore the connector 1 is improved. In addition, the curved fine piece 140 and the curved fine piece 150 may be formed collectively in the same process, or may be formed separately in different processes.

Next, while the free ends of the curved fine pieces 120 and 160 of the small pieces 101 with the carrier attached face the front (X1 direction), the curved pieces 140 of the small pieces 102 with the carrier attached , 150) with the free end facing the rear (X2 direction) (see FIG. 5), and a mold (upper mold (M1) to be described later, lower mold (M2) and It is placed in the rear mold (M3) and held by the mold. At this time, as shown in FIG. 5, the curved fine piece 120G serving as the ground terminal 20G has its front end in the vertical direction (Z-axis direction), which becomes the first bracket 40. While located immediately below the rear end of 140, in the connector width direction, the portion 141B corresponding to the first narrow arm portion 41B of the bent fine piece 140 serving as the first bracket 40 It is arranged to be within range. Further, the curved fine piece 120S serving as the signal terminal 120S is outside the range of the portion 141B in the connector width direction, and the range of the portion 141A corresponding to the first wide arm portion 41A Located within.

In this way, the upper and lower surfaces, which are the flat rolling surfaces of the first wide arm portion 41A and the first narrow arm portion 41B, are used as the contact surfaces with the mold.

In addition, the rear mold M3 is located at a portion corresponding to the rear frame portion 10B of the housing 10, of the groove upper portion 10B-2 (refer to FIG. 1(B)) of the housing 10. It has a protruding portion having the same width as the groove width, and the lower surface of the protruding portion abuts the upper surface of the upper surface of the terminal 20 to be held 23A. Thereby, the molten resin is prevented from flowing into the contact arm portion 21 side of the terminal 20 during integral mold molding, and a space for allowing the elastic displacement of the contact arm portion 21 is secured.

Moreover, as shown in FIG. 7(B), the upper mold M1 is the rear end region of the upper surface of the second wide arm portion 51A of the second bracket 50 and the second narrow arm portion 51B. A space for forming the second shaft portion 35B in contact with the rear end region of the upper surface is formed by being surrounded by the second wide arm portion 51A, the second narrow arm portion 51B, and the upper mold M1. Moreover, as shown in FIG. 7(B), the lower mold M2 abuts against the middle region in the front-rear direction in the lower surface of the lower arm part 51 of the 2nd bracket 50. In this way, the upper and lower surfaces, which are the flat rolling surfaces of the lower arm portion 51, are used as the contact surfaces with the mold.

Moreover, as shown in FIG. 8(B), at the position of the end plate part 34 of the movable member 30 in the connector width direction, the space for forming the end plate part 34 is the upper mold M1 ) And the lower mold (M2).

Next, the molten electrical insulating material (resin) is injected into a mold and then solidified, and the housing 10 and the movable member 30 are simultaneously molded, and the terminal 20, the first bracket 40, and the second bracket 50 and the third bracket 60 are held in the housing 10 by integral mold molding. As a result of this integral mold molding, as shown in Fig.6(B), at the position of the first bracket 40 in the connector width direction, the lower surface of the first narrow arm portion 41B of the upper arm 41 (rolling Surface), in the space surrounded by the lower mold M2 and the rear mold M3, the first shaft portion 35A of the movable member 30 is formed in a state in contact with the lower surface of the first narrow arm portion 41B from its upper surface do. Further, as shown in Fig. 6(B), the movable member 30 is molded in a state in the open position.

In addition, as shown in Fig. 7(B), at the position of the second bracket 50 in the connector width direction, in the accommodation hole 15A (refer to Fig. 7(A)) of the housing 10, In the space surrounded by the upper surface (rolling surface) of the lower arm portion 51 of the second bracket 50 and the upper mold M1, the second shaft portion 35B of the movable member 30 is the lower arm portion 51 at its lower surface. It is formed in contact with the upper surface of. In addition, as shown in Fig. 8(B), at the position of the end plate portion 34 of the movable member 30 in the connector width direction, in the space surrounded by the upper mold M1 and the lower mold M2, The end plate portion 34 is formed.

Next, it is separated by moving the upper mold M1 upward (Z1 direction), the lower mold M2 downward (Z2 direction), and the rear mold M3 rearward (X2 direction) and straight. After separating the molds (M1, M2, M3), the carrier (C1) from the small piece 101 to which the carrier is attached is excised at the position indicated by the dashed-dotted line (P1) in FIG. 5, and the carrier is attached. The carrier C2 is cut out from the fine piece 102 at the position indicated by the dashed-dotted line P2 in FIG. 5. As a result, the curved fine pieces 120 and 160 of the small pieces 101 to which the carrier is attached are formed as the terminal 20 and the third bracket 60, and the curved fine pieces of the small pieces 102 with the carrier are attached. (140, 150) are formed as the first bracket 40 and the second bracket 50.

Next, by performing an operation to rotate the movable member 30 from the open position to the closed position, the first shaft portion 35A of the movable member 30 is moved from the lower surface of the upper arm portion 41 of the first bracket 40. While separating, by separating the second shaft portion 35B of the movable member 30 from the upper surface of the lower arm portion 51 of the second bracket 50, and making the movable member 30 movable, the connector ( 1) is completed in a usable state. At this time, since the lower surface of the upper arm part 41 and the upper surface of the lower arm part 51 are rolled and smooth, the first shaft portion 35A and the second shaft portion 35B are easily separated. The rotational operation of the movable member 30 may be performed at any stage after the molds M1, M2, M3 are removed, for example, may be performed by the manufacturer before the connector 1 is shipped, or the connector is shipped. Thereafter, it may be implemented by the user at the start of use of the connector.

As described above, in the connector 1 according to the present embodiment, the terminal 20 and the brackets 40, 50, 60 are integrally molded with the housing 10 and the movable member 30 at the same time, and then the movable member 30 Can be manufactured by simply moving between the open position and the closed position. Therefore, as in the prior art, there is no need to process the constituent members of the connector after the integral mold molding, and the connector can be manufactured simply with fewer steps. Moreover, as the number of steps decreases, the manufacturing cost of the connector can be suppressed.

Next, the connection operation of the connector 1 and the flat conductor F is demonstrated based on FIGS. 9-11. Fig. 9 is a right angle with respect to the width direction of the connector in a state in which the flat conductor (F) is inserted immediately before insertion of the flat conductor (F), Fig. 11 is in a state in which the connection operation of the flat conductor (F) is completed. It is a cross-sectional view of the connector 1 on the seal surface, in each drawing, (A) is a cross-section at the position of the first bracket 40, (B) is the position of the engaging portion 33A of the movable member 30 A cross section in (C) shows the regulated portion 34A of the movable member 30. As shown in Fig. 11(A), the upper surface of the flat conductor F is pressurized under the first shaft portion 35A, and as a result, the contact arm portion 21 of the terminal 20 In the elastically deformed state of, the contact pressure between the circuit portion of the flat conductor F and the contact portion 21A of the terminal 20 is increased.

First, the connection part 22 of the terminal 20 of the connector 1 (the signal connection part 22S for the signal terminal 20S and the ground connection part 22G for the ground terminal 20G) is connected to a circuit board (not shown). The first fixing portion 42 of the first bracket 40, the second fixing portion 52 of the second bracket 50, and the third with a solder connection box to the corresponding circuit portion (signal pad and ground pad) of The third fixing part 62 of the bracket 60 is connected by soldering to the corresponding part of the circuit board (first fixing pad, second fixing pad, and third fixing pad). The housing 10 is fixed to the circuit board by solder connection of each of the fixing portions 42, 52, 62.

Next, as shown in Figs. 9A to 9C, a flat conductor F is attached to the rear of the connector 1 in a state in which the movable member 30 is brought to the open position. It is positioned so as to extend in the front-rear direction along the mounting surface (see FIG. 1 ). Next, the flat conductor F is inserted into the receiving portion 17A of the connector 1 facing the front.

In the process of inserting the flat conductor F into the receiving portion 17A, the front end of the flat conductor F is, first, as shown in Fig. 10A, the contact arm portion 21 of the terminal 20 ) Abuts against the contact portion 21A and presses down the contact portion 21A by the downward component of the contact force. At this time, the contact arm 21 is elastically displaced downward as shown in Fig. 10A.

Insertion of the flat conductor F is performed until the front end of the flat conductor F abuts against the rear surface of the front frame portion 10A of the housing 10 (see Figs. 10A and 10B). As shown in Fig. 10A, even in the state in which the flat conductor F is inserted, the contact arm portion 21 of the terminal 20 remains elastically displaced, and as a result, the contact arm portion ( The contact part 21A of 21) has a contact pressure with the connection circuit part exposed to the lower surface of the flat conductor F, and a contact state is maintained.

In addition, in this embodiment, as shown in FIG. 9(A) and FIG. 10(A), at the position of the rear opening of the accommodation part 17A, the protrusion of the rear frame part 10B of the housing 10 A groove upper portion 10B-2 lowered than the protruding portion is formed between the jaws 10B-1, and the upper surface of the terminal 20 to be held 23A is a groove upper portion 10B-2 on the upper surface thereof. ) Is positioned to form the same surface as the bottom of the groove (see also Fig. 1(B)). Therefore, in the process of insertion and extraction of the flat conductor F, even if the flat conductor F causes undesirable movement or inclination in the connector width direction, the lower surface of the flat conductor F abuts against the protruding portion ( It is the upper surface of 10B-1), and friction is not caused between the circuit portion of the lower surface of the flat conductor F and the terminal 20. As a result, the circuit portions of the terminal 20 and the balanced conductor F are protected.

Next, the movable member 30 is rotated, brought to the closed position as shown in Figs. 11 (A) to (C), and the locking portion of the movable member 30 as shown in Fig. 11 (B) 33A is rushed into the notch F1 of the flat conductor F. As a result, the part F2A to be caught of the flat conductor F is located in front of the locking surface 33A-1 of the locking part 33A and is positioned so as to be able to be engaged with the locking surface 33A-1, The ejection of (F) to the rear is prevented. By bringing the movable member 30 to the closed position in this way, the connection operation between the connector 1 and the flat conductor F is completed.

As shown in FIG. 11(C), in the state where the movable member 30 is in the closed position, the regulated part 34A of the movable member 30 is the rear recessed part 15C- of the housing 10. 1) It enters inside and is located under the regulation part 15C-2 of the housing 10, and the regulated surface 34A-1 (the upper surface in the closed position) of the regulated part 34A is the regulation part It faces with the regulation surface 15C-2A of (15C-2) in a state with a gap (rattle) in an up-down direction, and becomes a state in which it can engage. Therefore, for example, when the flat conductor F is suddenly lifted upward while connected to the connector 1, an external force or the movable member thereof that further rotates the movable member 30 that has rotated to the closed position ( Even if the movable member 30 receives an external force that lifts 30) upward, the regulated surface 34A-1 is caught by the regulation surface 15C-2A from below, so that the movable member 30 rotates or Movement is regulated. As a result, the movable member 30 is prevented from coming out of the housing 10.

Moreover, in this embodiment, the 1st width narrow arm part 41B of the 1st bracket 40 is located just above the 1st shaft part 35A of the movable member 30, and the 1st shaft part 35A further moves Since movement of the member 30 upward is prevented, the movable member 30 from the housing 10 is also prevented from being removed by the first narrow arm portion 41B.

In addition, in this embodiment, as can be seen by comparing FIGS. 11(A) and 11(C), the regulating part 15C-2 of the housing 10 is the first bracket 40 It is located rearward from the width narrow arm part 41B and the 1st shaft part 35A of the movable member 30. Therefore, when the flat conductor F is suddenly lifted upwards while connected to the connector 1, the flat conductor F is the regulating portion 15C-2 of the housing 10 and the movable member 30 ) Is lifted from the rear of the regulated portion 34A, and the first shaft portion 35A of the movable member 30 receives an upward force generated by the lifting force.

In the present embodiment, the first narrow arm portion 41B as a blocking portion of the first bracket 40 abuts (engages) with respect to the first shaft portion 35A as a inhibited portion of the movable member 30 from above, When the first width narrow arm portion 41B resists the upward movement of the movable member 30 against the upward force, but the lifting force acting on the balance conductor F is excessive In some cases, the first narrow arm portion 41B is elastically displaced upward and the movable member 30 is lifted. At that time, the regulated portion 34A of the movable member 30 is on the regulation surface 15C-2A of the regulation portion 15C-2 of the housing 10 from the regulated surface 34A-1. The movement of the movable member 30 to the upper side is regulated by abutting (engaging) from the lower side, and the control portion 15C-2 thereof.

When the movement of the regulated portion 34A is regulated by the regulation portion 15C-2, the regulation position becomes a supporting point, and the balance conductor F causes a large upward bending deformation. And, the movable member 30 receives a rotational force in the bending deformation direction of the balance conductor F at the first shaft portion 35A of the movable member 30 positioned at a position in front of the support point, and this force is applied to the movable member ( Since it acts in the direction of holding 30) in the closed position, it becomes easy to hold the movable member 30 in the closed position. As a result, when the lifting force acts on the balance conductor F, the movable member 30 in the closed position is prevented from rotating to the open position, and furthermore, the balance conductor F becomes the connector 1 Is prevented from falling out.

When the flat conductor F in the state shown in Figs. 11A to 11C, that is, in the connected state with the connector 1, is intentionally extracted from the connector 1, the movable member 30 in the closed position is removed. It is rotated and brought to the open position shown in Figs. 10(A) to (C). As shown in Fig. 10(B), when the movable member 30 is in the open position, the engaging portion 33A of the movable member 30 moves upward from the cutout F1 of the flat conductor F. It is located out of the way. In short, the locking state of the locking portion 33A with respect to the engaging portion F2A of the flat conductor F is released, and the ejection of the flat conductor F to the rear is allowed. And in this state, when the flat conductor F is pulled back, the flat conductor F can be easily extracted from the connector 1.
