FIG. 1 is a schematic partial cross-sectional view of an electronic device according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of a rigid support tube of the electronic device in FIG. 1 . It should be noted that, in order to clearly show the structure in which the wire assembly of the electronic device passes from the inside to the outside, FIG. 1 only shows a part of the electronic device.

Please refer to FIG. 1 and FIG. 2 , in this embodiment, the electronic device 100 includes a casing 110 , a wire assembly 120 and a waterproof glue 130 . The size of the electronic device 100 may be a miniaturized size, but is not limited thereto.

Only a part of the housing 110 is schematically shown in FIG. 1 , in particular a wall 113 of the housing 110 surrounding the hole 112 .

The wire assembly 120 extends from the inner space 111 of the housing 110 through the hole 112 to the outside of the housing 110 . The wire assembly 120 includes a plurality of wires 121 , a flexible conduit 122 covering the wires 121 , and a rigid support tube 123 between the wires 121 and the flexible conduit 122 . In this embodiment, these wires 121 may include charging wires 121 that can be used to charge the electronic device 100, and may also include signal transmission wires 121 to transmit signals into or out of the electronic device 100, and the types of wires 121 are not limited here limit.

Generally speaking, in order to simplify the number of exposed wires 121 and reduce the probability of these wires 121 being damaged, a flexible catheter 122 will be sheathed outside these wires 121, and these wires 121 can be regarded as a whole for more convenient access. , and these wires 121 can be protected.

However, since there is a gap between the flexible conduit 122 and these lead wires 121, in order to prevent the flexible conduit 122 from collapsing and deforming under long-term use or temperature changes, in this embodiment, a hard tube is provided between the lead wire 121 and the flexible conduit 122. The support tube 123 , the rigid support tube 123 is located inside the flexible conduit 122 and can provide support for the flexible conduit 122 . In this way, the probability of collapse or large deformation of the flexible conduit 122 of the lead assembly 120 can be reduced.

In addition, as can be seen in FIG. 1 , the waterproof colloid 130 is arranged between the wall 113 surrounding the hole 112 of the casing 110 and the lead assembly 120 to seal the gap between the wall 113 surrounding the hole 112 and the lead assembly 120 to avoid external The liquid flows in from the gap between the wall surface 113 and the wire assembly 120 to achieve a waterproof effect.

In this embodiment, since the rigid support tube 123 is located inside the flexible conduit 122, it can provide support for the flexible conduit 122, avoiding the collapse and deformation of the flexible conduit 122, and the position of the rigid support tube 123 will at least correspond to At the position of the waterproof colloid 130 , the rigid support tube 123 can further maintain the gap between the wall surface 113 and the flexible conduit 122 , so as to reduce the probability of the waterproof colloid 130 being broken due to the flexible conduit 122 being collapsed or greatly deformed.

For example, the rigid support tube 123 is at least located in the hole 112 and at least surrounds the wires 121 at a position corresponding to the wall 113 . Specifically, in this embodiment, as shown in FIG. 1 , the rigid support tube 123 has a first end 124 and a second end 125 opposite to each other, and the first end 124 is located in the hole 112 and is close to the inner space 111 , and the second end portion 125 is located outside the shell 110 , so that the rigid support tube 123 extends from the hole 112 of the shell 110 to the outside of the shell 110 . Of course, the relative position between the rigid support tube 123 and the shell 110 is not limited thereto.

It is worth mentioning that the technology of this embodiment can be applied to the microelectronic device 100 . Even if this type of miniature electronic device 100 is limited by space and cannot increase the strength of the flexible conduit 122 or the waterproof gel 130 by increasing the wall thickness of the flexible conduit 122 or increasing the thickness of the waterproof gel 130 outward, it can still be used in the flexible conduit 122 through this embodiment. The hard support tube 123 is arranged inside the conduit 122 to maintain the position of the flexible conduit 122 relative to the wall 113 , thereby avoiding deformation of the waterproof gel 130 and achieving good waterproofness. Of course, the technology of this embodiment can be applied to the non-miniature electronic device 100 , and it is not limited thereto.

In addition, since the rigid support tube 123 can effectively maintain the position of the flexible conduit 122 relative to the wall 113 , even if the bonding force between the material of the flexible conduit 122 and the waterproof colloid 130 is low, the waterproof effect will not be affected. The material of the flexible conduit 122 can be Teflon or PP, and the material of the rigid support tube 123 can be plastic, aluminum, copper or stainless steel, but the materials of the flexible conduit 122 and the rigid support tube 123 are not limited thereto.
