The mounting hole 1011 may be a circular hole, a square hole, a rectangular hole, or the like.

The insulating layer 103 is disposed in the casing 101, and forms a waterproof groove 105 with the casing 101.

The electronic device connects and fixes the isolation layer 103 and the housing 101 through other fixing members, or the isolation layer 103 is disposed on the housing 101 and forms an integral with the housing 101.

For example, the isolation layer 103 is connected to the housing 101 by fixing means such as bolt fixing and adhesive bonding, and the joint between the isolation layer 103 and the housing 101 is sealed. Alternatively, the housing 101 is provided with the isolation layer 103, and the isolation layer 103 is integrated with the housing 101.

The position of the waterproof groove 105 on the housing 101 corresponds to the position of the mounting hole 1011 on the housing 101, the mounting hole 1011 communicates with the waterproof groove 105, and the waterproof groove 105, the housing 101, and the key 102 form a first space on the side of the insulating layer 103. The waterproof plug 104 is attached to an opening at an end of the waterproof groove 105, and blocks the opening at the end of the waterproof groove 105 to isolate the first space and the second space on the other side of the isolation layer 103 from each other.

The first space includes the key 102, the waterproof groove 105 and the mounting hole 1011, and is communicated with the outside through the mounting hole 1011, and the second space is located inside the housing 101.

For example, a spring is disposed between the key 102 and the isolation layer 103, and one end of the spring is connected to the isolation layer 103, and the other end is connected to the key 102. Since the central axis of the mounting hole 1011 is perpendicular to the surface of the spacer 103, the electronic switch is pressed and the spring is also pressed when the key 102 moves into the mounting hole 1011. Then, when the key 102 is no longer acted by external force, the key is acted by spring pressure and moves in the direction away from the electronic switch, so that the key 102 is prevented from pressing the electronic switch for a long time.

In one possible implementation, the electronic device further includes a processor, and the processor is connected with the electronic switch.

The second through hole 1112 is communicated with the waterproof groove 105, and the first through hole 1111 is communicated with the waterproof groove 105 through the second through hole 1112. Because the size of the second through-hole 1112 is larger than that of the first through-hole 1111, a step, that is, a bent structure, is formed at a connection position of the inner wall of the first through-hole 1111 and the inner wall of the second through-hole 1112, and due to the bent structure, an object larger than the size of the first through-hole 1111 cannot enter the first through-hole 1111 through the second through-hole 1112.

The inner side of the button 102 is provided with a hanging ear structure 1021, and the size of the hanging ear structure 1021 is larger than that of the first through hole 1111. The button 102 is installed in the mounting hole 1011, and the hangers structure 1021 is located the second through-hole 1112, because the effect of blockking of structure of buckling, button 102 is along the center pin direction of first through-hole 1111, when moving to the direction of first through-hole 1111 by the second through-hole 1112, hangers structure 1021 and the contact of structure of buckling, can't make hangers structure 1021 enter into in the first through-hole 1111, then hangers structure 1021 stops to move, this structure of buckling produces limiting displacement to hangers structure 1021 to prevent that button 102 from droing in the mounting hole 1011.

In addition, the flexible circuit board 106 is connected to an electronic switch in the waterproof groove 105, and is connected to other components in the second space by bypassing the insulating layer 103 from an opening at an end of the waterproof groove 105. The electronic switch is pressed by the keys 102 to generate an electrical signal, and the electrical signal is transmitted to other components through the flexible circuit board 106. And the waterproof plug 104 and the flexible circuit board 106 block the waterproof groove 105 to isolate the first space and the second space from each other.

In addition, when the waterproof groove 105 is sealed by the waterproof plug 104 and the flexible circuit board 106, a gap is easily generated between the waterproof plug 104 and the flexible circuit board 106, and in order to improve the reliability of the waterproof groove 105 sealed by the waterproof plug 104 and the flexible circuit board 106, a groove is arranged on the isolation layer 103, and the flexible circuit board 106 is arranged in the groove.

The size of the groove is equal to that of the flexible circuit board 106, so that the flexible circuit board 106 can be positioned in the groove, and the gap between the groove and the flexible circuit board 106 can be reduced, so that the waterproof plug 104 and the flexible circuit board 106 can plug the waterproof groove 105 and the groove, and the first space and the second space are isolated from each other.
