  Since the main flexible board 11 cooperates with a key sheet having various key buttons, it is also called a key flexible board. As shown in FIGS. 3 and 4, the back side of the case 8 (the front side as a mobile phone). A main board body 11a attached to (inner side), an S-shaped drawer 11b for drawing a signal line from the main board body 11a, and a tip of the S-shaped drawer 11b. And an upper connector mounting portion 11c. The upper connector 13a is mounted on the upper connector mounting portion 11c. Here, as will be described later, the upper connector mounting portion 11c passes through the opening 8a formed in the lower end portion in FIG. 4 of the case 8, and enters the inside of the case 8 (the back side (outside) as a mobile phone). The stacking connector 13 is configured by fitting the upper connector 13a to the lower connector 13b inside the case 8 (FIGS. 3, 8, and 9). Note that the S-shaped lead-out portion 11b corresponds to a constricted portion because of its narrow width when viewed from the entire main flexible substrate 11.

A U-shaped lead portion 14b for drawing a signal line from the sub-board main body portion 14a, a lower connector mounting portion 14c provided at the tip of the U-shaped lead portion 14b and mounted with the lower connector 13b; From the right end portion of the lower connector mounting portion 14c, and from a pressing tongue piece 14d for facilitating blind work when fitting and connecting the upper connector 13a and the lower connector 13b at the time of device assembly. It is configured. Note that the U-shaped lead portion 14b corresponds to a constricted portion because of its narrow width when viewed from the entire sub-flexible substrate 14. An external connection connector 15 such as a SIM (Subscriber Identity Module) card connector, a silicon microphone 16, a spacer 17 and the like are mounted on the sub-board body 14a.

  In this example, the sub flexible board 14 is a board electrically inserted between the main flexible board (key flexible board) 11 and the control circuit board. The main flexible board (key flexible board) 11 is: It is connected to the stacking connector 13 and is connected to the control circuit board via a cable.

Next, the stacking connector connection structure of this example will be described with reference to FIGS.
First, in the main flexible substrate 11, as shown in FIG. 9, the main substrate body 11 a is attached and mounted on the back side (outside) of the case 8 with a double-sided adhesive tape. The S-shaped lead portion 11b is bent or curved in a direction facing the case 8 side, and with this help, the upper connector mounting portion 11c passes through the opening portion 8a provided in the case 8, and the case 8 It has been moved to the surface side (inside). On the surface side (inner side) of the case 8, the S-shaped lead portion 11 b is bent or curved again in a direction parallel to the surface of the case 8 (that is, so as to form an S shape as a whole). The fitting surface of the upper connector 13a mounted on the upper connector mounting portion 11c is directed downward. On the other hand, in the sub-flexible substrate 14 on the surface side (inner side) of the case 8, the U-shaped lead portion 14b is folded (bent or curved) into a U-shape as shown in FIG. The mating surface of the lower connector 13b mounted on the mounting portion 14c is directed upward, and the lower connector 13b is placed on the spacer stacked on the silicon microphone 16.

  According to the configuration of this example, it is possible to effectively use the empty space in the case (housing) 8 and contribute to the downsizing of electronic devices such as mobile phones.

Next, the stacking connector connection method of this example will be described with reference to FIG. 3 and FIGS.
To assemble the stacking connector connection structure of this example, first, as shown in FIG. 3, the main flexible substrate 11 is bent with the S-shaped lead-out portion 11 b (constricted portion) in the direction facing the case 8 side. Alternatively, the upper connector mounting portion 11c is moved to the surface side (inner side) of the case 8 by bending through the opening 8a provided in the case 8 with the help. Thereafter, the main board body 11a is attached and mounted on the back side (outside) of the case 8 using a double-sided adhesive tape.

  Next, after mounting the sub-flexible substrate 14 on the surface side (inner side) of the case 8, the U-shaped drawer portion 14b is folded (bent or curved) into a U-shape, with this help, The lower connector 13b is placed on the spacer stacked on the silicon microphone 16 with the mating surface of the lower connector 13b mounted on the lower connector mounting portion 14c in the upward posture. .

  After that, the main flexible board is formed on the front surface side (inside) of the case 8 while holding the pressing tongue piece 14d with a hand or a jig and holding the mating surface of the lower connector 13b in a proper upward posture. The S-shaped lead-out portion 11b on the 11th side is bent or bent again in the opposite direction so that the fitting surface of the upper connector 13a mounted on the upper connector mounting portion 11c is in a downward posture, and the lower connector 13b is covered. When the upper connector 13a with the fitting surface facing downward is stacked on the lower connector 13b with the fitting surface facing upward, and the upper connector 13a is fitted with the lower connector 13b, the stacking connector of this example This connection structure is completed (FIGS. 3, 7, 8, and 9).

The fitting connection work in the vertical direction between the upper connector 13a and the lower connector 13b is a blind work in which the situation of the fitting portion is not visible to the operator. Due to the reaction force (expansion force) against (folding back), it is not easy to accurately match the fitting position.
However, according to the connection method of this example, the operator merely presses the pressing tongue plate 14d lightly with a hand or a pressing tool, or while the pressing is being performed, the upper surface of the mating surface of the lower connector 13b faces upward. Since the posture can be maintained in an appropriate state, and therefore, the sub-flexible substrate 14 can be prevented from spreading due to a reaction force against bending or bending (folding), this kind of blind fitting work is further facilitated. Efficiency can be improved.
