[0047] Figure 1AIt is a schematic diagram of a wire waterproof grommet according to an embodiment of the utility model. Figure 1B yes Figure 1A Schematic diagram from another perspective. Figure 1C yes Figure 1A sectional view of . Figure 2A yes Figure 1A Schematic diagram of the waterproof wire grommet set on the wire. Please also refer to Figure 1A , Figure 1B , Figure 1C as well as Figure 2A . The present case provides a wire waterproof grommet 100, which is suitable for being sleeved on a wire 200. The wire waterproof grommet 100 includes a main body 110 and a thin film structure 120. The main body 110 has a groove 111 and an opening 112, wherein the groove 111 is arranged at the first end P1, and the opening 112 is arranged at the second end P2 relative to the first end P1. The bottom of the groove 111 has a flange structure 111a extending toward the second end P2. The thin film structure 120 is arranged at the bottom of the groove 111 and on the flange structure 111a. In other words, the size of the thin film structure 120 is the same as the size of the flange structure 111a. When the wire 200 passes through the wire waterproof grommet 100 from the first end P1 to the second end P2, the wire 200 penetrates the thin film structure 120, so that the flange structure 111a fits the wire 200.
[0048] In detail, the main body 110 is elastic. In this embodiment, the main body 110 can be made of a silicone material. In other embodiments, the main body 110 can also be made of other elastic materials, and the present invention is not limited thereto. On the other hand, in this embodiment, the wire waterproof grommet 100 is suitable for a wire 200 with a width between 10 mm and 14 mm, and the size of the film structure 120 and the caliber of the opening 112 are smaller than the width of the wire 200, so the wire 200 can fit tightly with the flange structure 111a and the opening 112 when passing through the wire waterproof grommet 100. In other embodiments, the wire waterproof grommet 100 may also be suitable for a wire 200 with a width greater than 14 mm or less than 10 mm, as long as the size of the film structure 120 and the diameter of the opening 112 are smaller than the width of the wire 200, so that when the wire 200 penetrates the film structure 120 and passes through the wire waterproof grommet 100, the wire 200 fits tightly with the flange structure 111a and the opening 112. The present invention is not limited to this.
[0049] On the other hand, the groove 111 also has a groove opening 111b. In this embodiment, the diameter of the groove opening 111b is larger than the diameter of the opening 112, so that the main body 110 presents a tapered structure. In other embodiments, the diameter of the groove opening 111b can also be equal to or smaller than the diameter of the opening 112, as long as the wire 200 can pass through the wire waterproof grommet 100 through the groove opening 111b, and the utility model is not limited thereto.
[0050] The wire waterproof grommet 100 further includes a snap-fit structure 113, which is disposed at the first end P1 and is disposed around the outside of the main body 110. The snap-fit structure 113 includes a snap-fit arm 113a and a protrusion 113b. The snap-fit arm 113a protrudes from the main body 110 and extends from the first end P1 to the second end P2. The protrusion 113b protrudes outward from the main body 110 and forms a snap-fit groove 113c with the snap-fit arm 113a and the main body 110.
[0051] Figure 1D yes Figure 1B Please also refer to Figure 1B and Figure 1D The main body 110 also has an annular structure 114, which protrudes from the edge of the opening 112 to the outside of the main body 110. In this embodiment, the wire waterproof grommet 100 also includes a strap 130, wherein the strap 130 is disposed on the annular structure 114 to better fix the wire waterproof grommet 100 to the wire 200. The main body 110 also has an inner protrusion 115, which is disposed on the inner edge of the opening 112.
[0052] Figure 2B yes Figure 2A Please also refer to Figure 2A and Figure 2B In this embodiment, when the wire waterproof grommet 100 is to be sleeved on the wire 200, the wire 200 passes through the main body 110 from the groove opening 111b, and fits the flange structure 111a after penetrating the film structure 120, and finally passes out from the opening 112. Since the width of the wire 200 is greater than the film structure 120 and the flange structure 111a, the wire 200 will fit closely with the flange structure 111a below the film structure 120 after penetrating the film structure 120, so that the wire 200 will not be separated from the wire waterproof grommet 100 when stretched. In addition, when the wire 200 passes through the wire waterproof grommet 100 and passes out from the opening 112, the inner protrusion 115 will fit the wire 200, so that the opening 112 of the wire waterproof grommet 100 and the wire 200 fit more closely.
[0053] In detail, the film structure 120 is set to a thickness that can be penetrated by the wire 200, so when the wire waterproof grommet 100 is set on the wire 200, the wire 200 can be used to directly penetrate the film structure 120. In addition, in this embodiment, the groove 111 is a structure that is recessed from the first end P1 to the second end P2, which can guide the wire 200 to be inserted into the main body 110 from the first end P1. In addition, the recessed structure of the groove 111 can make the groove 111 move toward the first end P1 as the wire 200 is stretched.
[0054] Figure 3A yes Figure 1A Schematic diagram of a wire waterproof grommet being set on a wire and reversely pulled. Figure 3B yes Figure 3A Please also refer to Figure 3A and Figure 3B In this embodiment, since the flange structure 111a is as elastic as the main body 110, the flange structure 111a moves with the wire 200 when the wire 200 is stretched. After the wire waterproof grommet 100 is sleeved on the wire 200, the wire 200 is stretched from the second end P2 to the first end P1, and the flange structure 111a extends with the wire 200 toward the first end P1. In other words, when the wire waterproof grommet 100 is sleeved on the wire 200, the movement of the wire 200 will not affect the tightness between the wire waterproof grommet 100 and the wire 200, and the stretching of the wire 200 toward the first end P1 can make the flange structure 111a fit the wire 200 more closely.
[0055] Figure 4A yes Figure 1A Schematic diagram of a wire waterproof grommet being fixed to the housing of an electronic device. Figure 4B yes Figure 4A Please also refer to Figure 4A and Figure 4B In this embodiment, when the wire waterproof grommet 100 is to be engaged with the housing 310 of the electronic device 300, the engaging arm 113a and the protrusion 113b are against the housing 310 of the electronic device 300, and the housing 310 of the electronic device 300 extends into the engaging structure 113 into the engaging groove 113c, so that the engaging structure 113 and the housing 310 of the electronic device 300 are tightly fitted.
[0056] In detail, when the wire 200 penetrates the film structure 120 of the wire waterproof grommet 100, the flange structure 111a provides a first layer of sealing. When the wire 200 passes through the opening 112, the inner protrusion 115 provides a second layer of sealing. Through the above two-layer sealing design, there is no gap between the wire 200 and the wire waterproof grommet 100, thereby achieving a waterproof and dustproof effect. On the other hand, the snap-fit structure 113 tightly fits the wire waterproof grommet 100 with the housing 310 of the electronic device 300, and the snap-fit arm 113a has a pointed structure extending from the first end P1 to the second end P2, which can achieve a better sealing effect with the housing 310 by using the wire contact housing 310, so that the wire waterproof grommet 100 and the housing 310 of the electronic device 300 achieve a waterproof and dustproof effect.
[0057] In summary, the utility model provides a wire waterproof grommet, which can be installed on the wire without tools through a thin film structure, so as to achieve quick installation and increase the convenience of assembly. In addition, through the flange structure and the clamping structure, the wire waterproof grommet fits the wire and the housing of the electronic device, achieving the effect of waterproof and dustproof.
