With the development of electronic communication technology, electronic devices having various functions are emerging. These electronic devices generally have a convergence function for performing one or more functions in a complex manner.

In recent years, as the functional gap between manufacturers is remarkably reduced, efforts are being made to increase the rigidity of electronic devices, which are becoming slimmer, and to strengthen the design aspects, in order to satisfy consumers' purchasing desires. As part of this trend, at least a part of various structures (eg, exterior) of the electronic device are implemented with a metal material to appeal to the high quality of the electronic device and the aesthetics of the appearance.

In addition, terminal manufacturers are making efforts for intuitive and diverse information delivery to users through slimmed electronic devices, and as a part of this, displays of various shapes for displaying information are being released.

Furthermore, a key button assembly for performing a switching function by physical pressure may be disposed in at least some areas of the electronic device, and efforts are being made to improve the assembly of the key button assembly and secure an advantageous key performance test.

In general, the electronic device may be arranged in such a way that at least a portion of at least one physical key button is exposed to the outside.

The method of assembling the key button from the outside of the set is to attach the FPCB to the main mechanism (eg, the housing of the electronic device) and insert the key button from the outside. However, in this case, since the key button and the FPCB can be assembled into a single device, this method has an advantage in that it is possible to test the performance of the key button such as the click feeling and lifespan of the key button before assembling the electronic device. However, when assembling the key button from the outside of the set, there is a disadvantage in that the appearance of the set is scratched. In addition, when the key button is assembled from the outside of the device, the amount of engagement of the key button is small, which causes a problem that the key button is separated from the outside of the device.

The method of assembling the key button from the inside is to assemble the key button to the main device (eg, the housing of the electronic device) first, then assemble the FPCB to another device (eg, the bracket), and then assemble the two devices. have.
