In order to achieve the above object, the present invention provides an outer cover, a first inner cover coupled to the rear of the outer cover, an external power button installed on the outer cover and the first inner cover, and the first inner cover. And a second inner cover installed at a rear side, and an inner power button installed on the second inner cover to be in contact with the external power button, the inner power button interlocking with the external power button to operate the tact switch of the substrate. A power button coupling structure is provided.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

Figure 2 is a longitudinal sectional view showing a state in which the external and internal power button is coupled according to the present invention, Figure 3 is an exploded perspective view showing a state in which the external power button according to the present invention is coupled, Figure 4 is an external according to the present invention Figure 5 is a longitudinal sectional view showing a state in which the power button is coupled, Figure 5 is an exploded perspective view showing a state in which the internal power button is coupled according to the present invention, Figure 6 is a longitudinal sectional view showing a state in which the internal power button is coupled according to the present invention 7 is a cross-sectional view showing a state in which the internal power button is coupled according to the present invention.

According to the present invention, a fusion protrusion (2) is formed behind the outer cover (1) of an image display device such as a computer monitor, and the fusion protrusion (2) is formed on the first inner cover (3) behind the outer cover (1). An insertion hole 4 to be inserted is formed, and the fusion protrusion 2 of the outer cover 1 is inserted into the insertion hole 4 of the first inner cover 3 to be heat-sealed, thereby forming the outer cover 1. 1, the inner cover 3 is coupled, and the outer power button 7 is inserted into the guide holes 5 and 6 formed in the outer cover 1 and the first inner cover 3, respectively. 1 A predetermined distance play is formed between the flange portion 8 formed on the inner circumferential surface of the guide hole 6 of the inner cover 3 and the flange portion 9 formed on the outer circumferential surface of the external power button 7.

In addition, a second inner cover 10 is installed at the rear of the first inner cover 3, and a substrate having a tact switch 11 and a light emitting diode 12 is provided at the rear of the second inner cover 10. The fastening member 15 such as a screw penetrates the fixing hole 14 formed in the substrate 13 to fix the 13, and is fastened to the fixing boss 16 formed at the rear of the second inner cover 10. An internal power button 18 is inserted into the guide hole 17 formed in the second inner cover 10 to contact the rear end of the external power button 7.
