周縁部１ａが高く形成される。 By the way, generally the recess 3 for inserting the connector is
is provided at a certain depth from the back surface of the case 1 (for example, Japanese Utility Model Application Publication No. 53-153493). However, due to restrictions such as the height and design of the internal instrument, the recess 3 for inserting the connector is provided at a certain depth. If it is not possible to install the connector in the case 1 without changing the depth of the recess 3 for inserting the connector, as shown in Fig. 3,
The peripheral edge 1a of the connector insertion recess is formed higher than the general back surface of the case 3.

であるため、はね上る。(Problem to be solved by the invention) However, since the tongue piece 2a that becomes the connector conductive part of the flexible printed board 2 must be provided on the peripheral edge 1a that is higher than the general back surface, the tongue piece of the flexible printed board 2 must be disposed. 2a has a problem in that it springs up due to reaction force, as shown from the dashed line to the dashed double dotted line in FIG. Here, if the width of the recess 3 for inserting the connector is very small, it will not spring up, but since this width is required to be wide enough to insert the connector, it will spring up.

シブルプリント板である。(Example) Hereinafter, an example of the present invention shown in the drawings will be described. In FIG. 1, reference numeral 1 denotes an instrument case made of resin, and various internal instruments for automobiles (not shown) are housed inside the instrument case. Reference numeral 2 designates a flexible printed board arranged and fixed on the back surface of the instrument case 1 in the same manner as in the conventional example shown in FIG.

る。 Reference numeral 3 denotes a recess for inserting a connector formed on the back surface of the case 1, and the peripheral edge 1a of the recess 3 is formed higher than the other part (one end of the back surface 1c) of the back surface of the case 1. 2a is a connecting tongue piece formed in a portion corresponding to the recess 3 of the flexible printed board 2;
This tongue piece 2a is bent stepwise into an upper piece along the recess peripheral edge 1a higher than the general back surface 1c of the case 1, and then bent downward into the recess 3.

とする。 In the above configuration, the flexible printed board 2
The tongue piece 2a is bent along the back surface of the case to form the recess 3.
inserted within. Here, since the peripheral edge 1a of the recess 3 is raised, the tongue 2a of the flexible printed board 2 is bent at nearly 180 degrees, and therefore tends to spring up due to its elastic force.

端面の引掛かり部１ｄで押さえる構造とする。 However, in this example, case 1
A continuous notch 1b is formed on the inner wall of the recess 3 and on the lower side of the inner wall opposite to the tongue 2a, so the tongue 2a of the flexible printed board 2 can be inserted through the notch 1b. The tongue piece 2a is made long enough so that it does not touch the internal instrument, and when the tongue piece 2a tries to spring up due to the reaction force, it is held down by the catch part 1d on the end face of the notch part 1b of the case 1.

従来は別部品を使用してはね上がり防止してい
たが、本実施例の構造であれば、使用部品の形状
を変えることだけで、舌片２ａのはね上がりを防
止できる。 Conventionally, a separate part was used to prevent the tongue piece 2a from flying up, but with the structure of this embodiment, it is possible to prevent the tongue piece 2a from flying up by simply changing the shape of the parts used.

側の導通部と圧接して電気的導通が保たれる。 Furthermore, by inserting and fitting a connecting connector (not shown) into the connector insertion recess 3, the tongue piece 2a is pressed against the connection surface of the connector, and the tongue piece 2a is inserted into the recess as shown by the dashed line in FIG. The conductive portion on the tongue piece 2a presses against the conductive portion on the connector side to maintain electrical continuity.

するのみでもよい）。 Note that the shape of the connector insertion recess 3 in which the peripheral edge 1a is formed higher than the general back surface 1c does not need to be applied to all the connector insertion recesses formed in the case 1, and it is not necessary to apply it to all the connector insertion recesses formed in the case 1. It is only necessary to apply it to the parts that are required due to restrictions such as height and design (for example, in the case of a device with three connector insertion recesses 3 as shown in Figure 2, the lower right connector (It may be applied only to the insertion recess).
