Therefore, it is not necessary to perform any processing on the constituent members of the connector after integral molding as in the related art, and the connector can be easily manufactured with a small number of steps. In addition, the manufacturing cost of the connector can be suppressed as the number of steps is reduced.

Next, the connection operation of the connector 1 and the flat conductor F will be described with reference to FIGS. 9 to 11 . 9 is a cross-sectional view showing the connector 1 on a surface at right angles to the connector width direction immediately before the insertion of the flat conductor F, and FIG. FIG. 11 is a cross-sectional view of the connector 1 at a surface at right angles to the direction of the connector, and FIG. 11 is a cross-sectional view of the connector 1 at a surface at right angles to the connector width direction in a state where the connection operation of the flat conductor F is completed. Among them, (A) shows the cross section at the position of the first terminal 40 , (B) shows the cross section at the position of the locking portion 33A of the movable member 30 , and (C) shows the position of the movable member 30 The restricted portion 34A. 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 flat conductor is in a state where the contact arm portion 21 of the terminal 20 is elastically deformed. The contact pressure between the circuit portion of F and the contact portion 21A of the terminal 20 is increased.

First, the connection portion 22 of the terminal 20 of the connector 1 (the signal connection portion 22S of the signal terminal 20S and the ground connection portion 22G of the ground terminal 20G) is soldered and connected to the corresponding circuit portion (signal connection portion 22G of the circuit board (not shown)) pads and ground pads), and the first fixing portion 42 of the first metal fitting 40, the second fixing portion 52 of the second metal fitting 50, and the third fixing portion 62 of the third metal fitting 60 are welded and connected to Corresponding parts of the circuit board (the first fixing pad, the second fixing pad, and the third fixing pad). The housing 10 is fixed to the circuit board by solder connection of the respective fixing portions 42 , 52 , 62 .

Next, as shown in (A) to (C) of FIG. 9 , 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 as to bring the movable member 30 to the The rear of the connector 1 in the state of the open position (see also FIG. 1 ). Then, 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, as shown in FIG. 10(A) , the front end of the flat conductor F first comes into contact with the contact portion 21A of the contact arm portion 21 of the terminal 20 , so as to abut against the contact portion 21A of the contact arm portion 21 of the terminal 20 The downward direction component of the relay pushes down the contact portion 21A. At this time, the contact arm portion 21 is elastically displaced downward as shown in FIG. 10(A) .

The flat conductor F is inserted 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) , in the state where the insertion of the flat conductor F is completed, the contact arm portion 21 of the terminal 20 remains in the elastically displaced state, and as a result, the contact portion of the contact arm portion 21 21A is maintained in a state of being in contact with the connection circuit portion exposed on the lower surface of the flat conductor F with a contact pressure.

In addition, in the present embodiment, as shown in FIGS. 9(A) and 10(A) , the protruding rib portion of the rear frame portion 10B of the housing 10 is formed at the position where the rear portion of the receiving portion 17A is opened. The grooves 10B-2 between 10B-1 and 10B-2 are recessed from the protrusions, and the upper surface of the terminal 20 is exposed to the held portion 23A at a position where the upper surface and the groove bottom of the groove 10B-2 form the same plane (See also (B) of FIG. 1 ). Therefore, even if the flat conductor F is undesiredly moved and inclined in the connector width direction during the insertion and removal of the flat conductor F, the lower surface of the flat conductor F is in contact with the protruding portion 10B. -1 upper surface, so that friction is not generated between the circuit portion of 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 bring the movable member 30 to the closed position as shown in (A) to (C) of FIG. 11 , and as shown in (B) of FIG. 11 , the movable member 30 is rotated The locking portion 33A of 30 enters into the cutout portion F1 of the flat conductor F. As a result, the to-be-locked portion F2A of the flat conductor F is located in front of the locking surface 33A-1 of the locking portion 33A and at a position where it can be locked with the locking surface 33A-1. Therefore, the flat conductor F Pulling towards the rear is blocked. 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 15C of the housing 10 Below -2, the restricted surface 34A-1 (upper surface in the closed position) of the restricted portion 34A and the restricting surface 15C-2A of the restricting portion 15C-2 face each other with a gap (loosening) in the up-down direction, Constitutes 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 that further rotates the movable member 30 turned to the closed position or receives a The rotation and movement of the movable member 30 are also restricted because the restricted surface 34A-1 is locked to the restriction surface 15C-2A from below by the external force that lifts the movable member 30 upward. As a result, the disengagement of the movable member 30 from the housing 10 is prevented.

In addition, in the present embodiment, the first narrow arm portion 41B of the first metal fitting 40 is positioned directly above the first shaft portion 35A of the movable member 30 to prevent the first shaft portion 35A, and more specifically the movable member 30 . In the upward movement, the movable member 30 is also prevented from being disengaged from the housing 10 by the first narrow arm portion 41B described above.

The first shaft portion 35A of 30 is positioned rearward. Therefore, when the flat conductor F is accidentally lifted upward in the state of being connected to the connector 1 , the flat conductor F is located behind the restricting portion 15C- 2 of the housing 10 and the restricted portion 34A of the movable member 30 . The first shaft portion 35A of the movable member 30 receives an upward force due to the lift-up force.

In the present embodiment, the first narrow arm portion 41B that is the blocking portion of the first metal fitting 40 abuts (locks) the first shaft portion 35A that is the blocked portion of the movable member 30 from above. The first narrow arm portion 41B prevents the upward movement of the movable member 30 against the above-mentioned upward force. However, when the above-mentioned lifting force acting on the flat conductor F is too large, the first narrow arm portion may 41B is elastically displaced upward to lift up the movable member 30 . 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 through the restricted surface 34A from below, and passes through the restricting portion 15C-2 , the upward movement of the movable member 30 is restricted.

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 largely deflected upward. Next, the movable member 30 receives a rotational force in the bending direction of the flat conductor F through the first shaft portion 35A of the movable member 30 at a position forward of the above-mentioned fulcrum, and this force acts on the movable member 30 It is maintained in the direction of the closed position, and therefore, it is easy to maintain the movable member 30 in the closed position. As a result, when the above-mentioned 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 further, the flat conductor F is pulled out from the connector 1. A situation is prevented.

In the states shown in (A) to (C) of FIG. 11 , that is, when the flat conductor F in the state connected to the connector 1 is intended to be pulled out from the connector 1 , the available The movable member 30 is rotated to bring the movable member 30 to the open position shown in (A) to (C) of FIG. 10 .
