ネクタの低背化に障害となる。However, this connector usually has many terminals, and the pressing member is long in a direction perpendicular to the paper surface. In the known connector shown in FIG. 4, the pressing member is closed. During rotation toward, the reaction force from these terminals may be deflected by receiving via the flexible substrate,
In that case, there is a possibility that it will come off from the rotation support portion. Therefore, in order to prevent detachment due to this bending, the pressing member is made thick to ensure sufficient rigidity, which is an obstacle to reducing the height of the connector.

う。As described above, there is a tendency that the contact pressure between the two terminals and the flexible substrate does not become the same, and particularly that the contact pressure at the contact portion located at the back cannot be sufficiently obtained. is there. In order to cope with this, generally, the groove of the housing into which the flexible board is inserted is narrowed in the height direction toward the back to secure the contact pressure.
However, the flexible substrate may not be able to be fully inserted to a predetermined position, and in that case, a positional shift occurs between the flexible substrate and the contact pressure. In addition, since the elastically deformable region of the contact portion located at the back is provided, the size of the connector itself increases.

じ接圧のもとになされる。Such a connector is used and operates in the following manner. First, a connector is arranged on a circuit board (not shown), and connection portions 14 and 26 of the two types of terminals 10 and 20 are respectively connected to corresponding circuit portions of the circuit board by soldering. Next, the pressing member 30 is moved to the position shown in FIG.
Is brought to the open position seen in FIG. Since the pressing member 30 is brought to the open position, the flexible substrate P is inserted into the opening 4 that is largely opened to the left. The flexible substrate P has a plurality of connection circuit portions P1 and P2 formed on the lower surface, and the respective connection circuit portions are positioned on the contact portions 12A and 22A of the terminals 10 and 20 by inserting the connection circuit portions to predetermined positions. (See FIG. 1C). After that, as shown in FIG. 1 (A) -2 and FIG. 1 (B) -2,
The pressing member 30 is turned downward. As described above, this rotation is performed by the rotation guided portion 31A of the pressing member 30.
Is in contact with the rotation guide portion 21A of the terminal 20, and the sliding portion 3
This is performed while maintaining the state where 1B is in contact with the sliding guide portion 21B of the terminal 20. That is, during the rotation, the pressing member 30 rotates while sandwiching the terminal 20 from above and below oppositely. The pressing member 30 presses the flexible substrate P by the pressing unit 33 and presses the flexible substrate P against the contact unit 12A of the terminal 10. Thus, the flexible substrate P is electrically connected to the terminal 10 under a sufficient contact pressure. The lower arm portion 12 of the terminal 10 is elastically bent downward when pressed by the flexible substrate P at the contact portion 12A. This bending causes the upper arm 11 to have a displacement angle at the connecting portion 13. As a result, the upper arm 11 is displaced downward. The displaced upper arm 11 presses the flexible substrate P downward from above. The flexible substrate P pressed by the upper arm 11 is pressed against the contact portion 22A of the lower arm 22 of another terminal 20, and is electrically connected to the terminal 20 here (FIG. 1B).
2-2, see FIG. 1 (D)). The connection with the terminal 20 is made under substantially the same contact pressure as the terminal 10 due to the rigidity of the flexible substrate.

薄型、すなわち、いわゆる低背化が可能となる。In the present embodiment, as described above, even if the pressing member is made thin, the flexible substrate contacts both terminals with a sufficient contact pressure and with a uniform contact pressure. Also, there is no need to provide a curved arm portion for elastically deforming the contact portion at the back portion so as to enable pinching. Therefore, by reducing the thickness of the pressing member, the entire connector can be made thinner, that is, so-called a low profile.

のが良い。The second embodiment is characterized in that a plate-like intermediate member 40 is disposed between the upper arm of the two types of terminals and the flexible substrate. This intermediary member has the same effect as increasing the rigidity of the flexible board, and therefore, when pressed by the upper arm portion 11 of the terminal 10, the contact pressures of the plurality of contact portions of both terminals are more reliably made uniform. . In order not to impair the effect of miniaturization of the connector of the present invention, it is preferable that the intermediate member 40 is thin, and is made of a highly rigid insulating material or a metal member coated with insulation.

Also, the upper arm and the lower arm of the terminal are arranged upside down as shown in FIGS. 1 and 2, so that the flexible substrate is also pressed against the upper arm from below to above. This is different from the previous example. Therefore, in FIG. 3, attention is paid to the function, the reference numerals assigned to the upper arm in the above example are assigned to the lower arm in the present embodiment, and the reference numerals assigned to the lower arm are assigned to the upper arm, and The form and function are easy to understand.

する。In FIG. 3, a plate-shaped pressing member 50 having a tapered surface 51 formed at the front edge slides on a guide surface 1A formed on the housing to move from below the flexible substrate P from the left. It is inserted linearly (FIG. 3 (A) -1). The pressing member 50 is smoothly inserted at the tapered surface 51,
The flexible substrate P is pushed upward to enter a predetermined position (FIG. 3A-2). Thus, the flexible substrate P
Makes contact with the contact portion 12A of the upper arm portion 12 of the terminal 10 under a sufficient contact pressure. The upper arm 12 is elastically bent upward due to the contact pressure, and accordingly, the lower arm 11 is also displaced upward.
