[Industrial applications]

 The present invention relates to a panel mounting structure mounted on an end surface of a substrate.

[0002]

[Prior Art]

 7 to 9 show conventional electronic devices.

The housing of this electronic device is composed of an upper case 1, a lower case 2, a front panel 3 and a rear panel 4, and the front panel 3 has one end side of a printed wiring board (board) 5. The rear panel 4 is fixed and has a hole 4a formed in the other end of the substrate 5 into which an electronic component 7 such as a connector is inserted. Further, as shown in FIG. 9, the inner wall of the upper case 1 is provided with a groove 9 into which the upper end of the rear panel 4 is inserted and a boss 10 for pressing the substrate 5, and the inner wall of the lower case 2 is provided with the rear panel 4. A groove 12 into which the lower end is inserted and a boss 13 for pressing the substrate 5 are provided.

Further, as shown in FIG. 8, when assembling an electronic device, the electronic component 7 is inserted into the hole 4a to bring the rear panel 4 into contact with the end surface 5a of the substrate 5, and the lower case is held while maintaining this state. 2, the lower end of the rear panel 4 is inserted into the groove 12, the upper case 1 covers the substrate 5, and the upper end of the rear panel 4 is inserted into the groove 9. This is done by screwing the bosses 10 and 13.

However, according to this conventional electronic device, the rear panel 4 is held only by inserting the both ends into the grooves 9 and 12 of the upper and lower cases 1 and 2, so that an assembly error and a component error may occur. Therefore, the back panel 4 was wobbled in the up-down direction (the direction of the arrow shown in FIG. 9) and in the left-right direction (the direction orthogonal to the paper surface). As a result, the gap between the hole 4a and the electronic component 7 cannot be kept constant in the vertical and horizontal directions of the electronic component 7, resulting in a poor appearance.

Further, when the substrate 5 and the rear panel 4 are attached to the upper and lower cases 1 and 2, both ends of the panel 4 are moved up and down while maintaining a state in which the electronic component 7 is inserted into the hole 4a. Since it is necessary to insert the grooves into the grooves 9 and 12 of the cases 1 and 2, the mounting work of the substrate 5 and the panel 4 is complicated.
