The lower surface of the convex portion is in contact with the upper surface of the terminal 20 to expose the upper surface of the held portion 23A. This prevents molten resin from flowing into the contact arm portion 21 side of the terminal 20 during integral mold molding, and secures a space for allowing elastic displacement of the contact arm portion 21 .

Also, as shown in FIG. 7(B) , the upper mold M1 is in contact with the rear end side region of the upper surface of the second width wide arm portion 51A of the second fastener 50 and the upper surface of the second width narrow arm portion 51B. In the rear end region, the space for forming the second shaft portion 35B is 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 side metal mold|die M2 is contact|abutted to the intermediate area in the front-back direction in the lower surface of the lower arm part 51 of the 2nd fastener 50. In this way, the flat rolling surfaces of the lower arm portion 51 , that is, the upper surface and the lower surface can be used as abutting surfaces with which the mold abuts.

Also, 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, the space for forming the end plate portion 34 is formed by the upper mold M1 and the lower mold M2 surrounded by formation.

Next, the melted electrical insulating material (resin) is injected into the mold and then solidified, the case 10 and the movable member 30 are simultaneously formed, and the terminal 20, the first terminal 20 and the first The fastener 40, the second fastener 50 and the third fastener 60 are retained. As a result of this integral mold forming, as shown in FIG. 6(B), the position of the first fastener 40 in the connector width direction is on the lower surface (rolled) of the first width narrow arm portion 41B of the upper arm portion 41. 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 where the upper surface of the movable member 30 is in contact with the lower surface of the first narrow arm portion 41B. Moreover, as shown in FIG.6(B), the movable member 30 is formed in the state which exists in an open position.

Also, as shown in FIG. 7(B), the position of the second fastener 50 in the connector width direction is within the receiving hole portion 15A (refer to FIG. 7(A) ) of the housing 10, and the second fastener is In the space surrounded by the upper surface (rolling surface) of the lower arm portion 51 of the tool 50 and the upper die M1, the second shaft portion 35B of the movable member 30 is in a state where the lower surface of the second shaft portion 35B is in contact with the upper surface of the lower arm portion 51 formed below. 8(B), at the position of the end plate portion 34 of the movable member 30 in the connector width direction, the end plate portion 34 is formed in the space surrounded by the upper mold M1 and the lower mold M2.

Next, it is removed by moving the upper mold M1 upward (Z1 direction), the lower mold M2 downward (Z2 direction), and the rear mold M3 backward (X2 direction). After removing the molds M1, M2, and M3, the carrier C1 is cut out from the thin strip 101 with the carrier at the position shown by the one-dot chain line P1 in FIG. Cut off at the point shown by the lock line P2. As a result, the curved thin strips 120 and 160 with the carrier thin strip 101 are formed as the terminal 20 and the third fastener 60, and the curved thin strips 140 and 150 with the carrier thin strip 102 are formed as the first fastener 40 and the third fastener 60. Two fasteners 50 are formed.

Next, by performing an operation of rotating the movable member 30 from the open position to the closed position side, the first shaft portion 35A of the movable member 30 is separated from the lower surface of the upper arm portion 41 of the first fastener 40, and the movable member 30 is separated from the lower surface of the upper arm portion 41 of the first fastener 40. The second shaft portion 35B of the member 30 is separated from the upper surface of the lower arm portion 51 of the second fastener 50, and the movable member 30 is made movable, thereby completing the connector 1 in a usable state. At this time, since the lower surface of the upper arm portion 41 and the upper surface of the lower arm portion 51 are rolled surfaces and are smooth, the first shaft portion 35A and the second shaft portion 35B are easily separated. The rotating operation of the movable member 30 can be performed at a stage after removing the molds M1, M2, M3. For example, it can be performed by the manufacturer before the connector 1 is shipped, or after the connector is shipped. It is done by the user before starting to use the connector.

In this way, in the connector 1 of the present embodiment, only after the terminal 20 and the fasteners 40, 50, 60 are integrally molded with the housing 10 and the movable member 30 at the same time, the movable member 30 is in the open position and the movable member 30 is closed. Move between positions to make. Therefore, it is not necessary to perform some processing on the constituent members of the connector after the integral mold molding as in the past, and the connector can be easily manufactured with a small number of processes. In addition, since the number of manufacturing processes is reduced, the manufacturing cost of the connector can also be suppressed in this part.

Next, the connection operation of the connector 1 and the flat conductor F will be described with reference to FIGS. 9 to 11 . Fig. 9 shows the state before the insertion of the flat conductor F, Fig. 10 shows the state where the insertion of the flat conductor F is completed, and Fig. 11 shows the state after the connection operation of the flat conductor F is completed. The cross-sectional view of the connector 1, in each figure, (A) is a cross-section at the position of the first fastener 40, (B) is a cross-section showing the position of the locking portion 33A of the movable member 30, ( C) shows the restricted portion 34A of the movable member 30 . As shown in FIG. 11(A) , the upper surface of the flat conductor F is pressed against the lower part of the first shaft portion 35A, and as a result, the circuit of the flat conductor F is improved in the elastic deformation state of the contact arm portion 21 of the terminal 20 The contact pressure between the part and the contact part 21A of the terminal 20 .

First, solder the connection portion 22 of the terminal 20 of the connector 1 (the signal terminal 20S is the signal connection portion 22S and the ground terminal 20G is the ground connection portion 22G) to the corresponding circuit portion (signal connection portion 22G) of the circuit board (not shown). Solder the first fixing part 42 of the first fastener 40, the second fixing part 52 of the second fastener 50, and the third fixing part 62 of the third fastener 60 by soldering on the corresponding part of the circuit substrate (the first fixed pad, the second fixed pad, and the third fixed pad). The case 10 is fixed to the circuit board by the solder connection of the fixing portions 42 , 52 and 62 .

Next, as shown in FIGS. 9(A) to (C), the flat conductor F is positioned so as to extend in the front-rear direction along the mounting surface of the circuit board (not shown) so that the movable member 30 has come to the open position The rear of the connector 1 in its state (see also Figure 1). Next, the flat conductor F is inserted into the receiving portion 17A of the connector 1 toward the front.

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

The insertion of the flat conductor F is performed until the front end of the flat conductor F abuts on the rear surface of the front frame portion 10A of the case 10 (see FIGS. 10(A) and (B) ). As shown in FIG. 10(A) , even in the state in which the insertion of the flat conductor F is completed, the contact arm portion 21 of the terminal 20 maintains a state of elastic displacement. As a result, the contact portion 21A of the contact arm portion 21 is maintained by the A state in which the contact pressure is in contact with the connection circuit portion exposed on the lower surface of the flat conductor F.

Furthermore, in this embodiment, as shown in FIGS. 9(A) and 10(A) , at the position where the rear portion of the receiving portion 17A is opened, between the protruding strip portions 10B-1 of the rear frame portion 10B of the casing 10 The groove-shaped portion 10B-2 which is more concave than the protruding strip portion is formed, and the upper surface of the terminal 20 exposed to the retained portion 23A is formed on the same surface as the groove bottom surface of the groove-shaped portion 10B-2. Refer to Figure 1(B)). Therefore, during the insertion and removal process of the flat conductor F, even if the flat conductor F is not moved or tilted badly in the width direction of the connector, the lower surface of the flat conductor F is in contact with the protrusion 10B- The upper surface of 1 does not generate friction between the circuit portion on the lower surface of the flat conductor F and the terminal 20 . As a result, the terminal 20 and the circuit portion of the flat conductor F are protected.

Next, the movable member 30 is rotated to come to the closed position as shown in FIGS. 11(A) to (C), and then, as shown in FIG. 11(B), the engaging portion 33A of the movable member 30 is protruded into the flat conductor The notch portion F1 of F. As a result, the locked portion F2A of the flat conductor F is located in front of the locking surface 33A-1 of the locking portion 33A, and is located at a position where the locking surface 33A-1 can be locked. Conductor F is pulled out toward the rear. In this way, by bringing the movable member 30 to the closed position, the connection operation of the connector 1 and the flat conductor F is completed.

As shown in FIG. 11(C) , when the movable member 30 is in the closed position, the restricted portion 34A of the movable member 30 enters the rear recess 15C- 1 of the housing 10 and is located in the restriction portion of the housing 10 Below 15C-2, the restricted surface 34A-1 (upper surface in the closed position) of the restricted portion 34A is in a state of having a gap (slot) in the vertical direction with respect to the restricting surface 15C-2A of the restricting portion 15C-2. Faced, it is in a lockable state. Therefore, for example, when the flat conductor F is accidentally lifted upward in the state of being connected to the connector 1, even if the movable member 30 receives an external force to further rotate the movable member 30 that has been rotated to the closed position, the movable member 30 will not be moved. When the member 30 is lifted upward by an external force or the like, the above-mentioned restricted surface 34A-1 is engaged with the above-mentioned restricting surface 15C-2A from below, and the rotation, movement, etc. of the movable member 30 can be restricted. As a result, the movable member 30 can be prevented from being detached from the casing 10 .

In addition, in this embodiment, the first narrow arm portion 41B of the first fastener 40 is located directly above the first shaft portion 35A of the movable member 30, so that the first shaft portion 35A and the movable member 30 are prevented from moving upward, Therefore, even by the aforementioned first narrow-width arm portion 41B, the movable member 30 can be prevented from being detached from the housing 10 .

11(A) and FIG. 11(C), it can be seen that the restricting portion 15C- 2 of the housing 10 is located at the arm portion 41B and the movable member that are narrower than the first width of the first fastener 40 in this embodiment. The first shaft portion 35A of 30 is further rearward. Therefore, when the flat conductor F is accidentally lifted upward while being connected to the connector 1 , the flat conductor F is tied at a position higher than the restricting portion 15C- 2 of the housing 10 and the restricted portion 34A of the movable member 30 . The rear receives the lifting force, and the first shaft portion 35A of the movable member 30 receives the upward force generated by the lifting force.

In the present embodiment, since the first narrow arm portion 41B of the first fastener 40 as the preventing portion is in contact with the first shaft portion 35A as the prevented portion of the movable member 30, the first shaft portion 35A is abutted (locked) from above. Therefore, the first-width narrow arm portion 41B resists the upward force and prevents the movable member 30 from moving upward. However, when the lifting force acting on the flat conductor F is too large, the first width is narrow. The arm portion 41B is elastically displaced upward, and the movable member 30 is lifted. At this time, the restricted portion 34A of the movable member 30 abuts (locks) with the restricting surface 15C-2A of the restricting portion 15C-2 of the housing 10 from below by the restricted surface 34A-1 thereof, and the restriction The portion 15C-2 restricts the upward movement of the movable member 30 .

When the movement of the restricted portion 34A is restricted by the restriction portion 15C- 2 , the restricted position becomes a fulcrum, and the flat conductor F is greatly bent upward and flexed. Then, the movable member 30 receives a rotational force in the bending and flexing direction of the flat conductor F through the first shaft portion 35A of the movable member 30 located more forward than the aforementioned fulcrum, and this force acts to close the movable member 30 Therefore, the movable member 30 is easily maintained in the closed position. As a result, when the aforementioned lifting force acts on the flat conductor F, the movable member 30 in the closed position is prevented from rotating toward the open position, and the flat conductor F is prevented from being detached from the connector 1 .

When the flat conductor F in the state shown in FIGS. 11(A) to (C), that is, in the connected state with the connector 1, is to be intentionally pulled out from the connector 1, let the The movable member 30 of the position is rotated so that it reaches the open position as shown in FIGS. 10(A) to (C). As shown in FIG. 10(B) , when the movable member 30 is located at the open position, the locking portion 33A of the movable member 30 is separated from the notch portion F1 of the flat conductor F upward and exists. That is, the latched state of the latched portion F2A of the rectangular conductor F by the latching portion 33A is released, and the rectangular conductor F is allowed to be pulled out backward. In addition, when the flat conductor F is pulled backward in this state, the flat conductor F can be easily pulled out from the connector 1 .
