Description

Technical Field

[0001] This application relates to the field of waterproofing technology for electronic devices, and more particularly to a waterproof structure and electronic device. Background Technology

[0002] Electronic devices typically require wiring to transmit electrical signals or power. However, water or moisture can easily seep into the electronic device through gaps between the wiring and the device's casing, causing a short circuit and rendering the device unusable. Therefore, it is necessary to install a waterproof structure between the wiring and the device's casing.

[0003] Currently, most manufacturers use waterproof rings on the SR (Strain Relief) end of wires. When assembling the wire into electronic devices, the waterproof ring fills the gap between the SR end and the device casing to prevent water leakage. To prevent misalignment, the SR end of the wire has a corresponding positioning groove. Before assembling the wire into the electronic device, the waterproof ring needs to be fitted into the positioning groove. However, the size of the SR end of the wire is larger than the size of the positioning groove. Therefore, during assembly, the waterproof ring needs to be stretched to pass through the SR end and finally be fixed in the positioning groove. Fitting the waterproof ring onto the SR end is generally done manually by workers, resulting in low assembly efficiency and high labor costs. Furthermore, during this assembly process, the waterproof ring is prone to contacting the terminals of the internal core wires, causing deformation and leading to wire defects. Addressing these defects adds further costs.

[0004] Therefore, the above problems need to be addressed. Utility Model Content

[0005] According to one aspect of the embodiments of this application, a waterproof structure is provided that effectively waterproofs while also saving costs. The waterproof structure includes a wire and a sheet material. The wire includes an SR end, and the SR end includes a waterproof section. The waterproof section has a circumferentially surrounding waterproof rib, and the waterproof rib and the waterproof section are integrally formed. The sheet material includes a first sub-plate and a second sub-plate, which are detachably connected. The first sub-plate includes a first mounting groove, and the second sub-plate includes a second mounting groove. The first mounting groove and the second mounting groove can be positioned and assembled into a positioning part. The positioning part includes a first mating groove and a second mating groove. The waterproof section can engage with the first mating groove for positioning, and the waterproof rib can be sealed with the second mating groove.

[0006] Compared with existing technologies, the waterproof structure provided in this application uses a waterproof section at the SR end of the wire to mate with the first mating groove of the positioning part, and an integrally formed waterproof rib on the waterproof section to seal with the second mating groove of the positioning part. This not only positions the SR end of the wire but also seals the area between the SR end and the second mating groove for waterproofing. The integral structure of the waterproof rib and the waterproof section eliminates the need for manual installation of the waterproof rib, improving work efficiency and saving labor costs. Furthermore, since there is no need to assemble the waterproof rib with the waterproof section, it avoids deformation of the wire core terminals due to contact with the waterproof rib, thus preventing defects during assembly and further saving costs. Therefore, the waterproof structure provided in this application effectively waterproofs while saving costs.

[0007] Specifically, the waterproof reinforcing strip and the second mating groove are in elastic abutting contact, and the waterproof reinforcing strip and the second mating groove are in an interference fit. This arrangement ensures that the waterproof reinforcing strip is always in abutting contact with the second mating groove to stably seal the gap between them, thereby effectively isolating moisture.

[0008] Specifically, the waterproof section fits the first mating groove with zero clearance. This design facilitates the interception of slow-moving seepage water or water vapor.

[0009] Specifically, the SR end further includes an engaging groove, and the positioning part further includes an engaging protrusion, the engaging groove being able to engage with the engaging protrusion. This design facilitates further positioning of the SR end and buffers the water flow, thereby reducing water intrusion.

[0010] Specifically, the waterproof section has engagement grooves on both sides, and the second mating groove has engagement protrusions on both sides. This design makes the positioning of the SR end more precise, thereby ensuring a good fit between the waterproof section and the first mating groove, and allowing the waterproof rib to maintain stable pressure against the second mating groove, thus improving the stability of use.

[0011] Specifically, the engaging groove and the engaging protrusion transition into each other. This design facilitates the initial positioning and assembly of the SR end of the wire with the board, thereby improving work efficiency.

[0012] Specifically, the positioning part is provided with a filling strip, which is used to fill the gap between the SR end and the positioning part after being irradiated by ultrasound. This arrangement can fill the tiny gaps between the SR end and the positioning part, thereby preventing the entry of fine moisture.

[0013] Specifically, the SR end is further provided with a locking terminal on the side facing the plate. The locking terminal can simultaneously engage with both the first sub-plate and the second sub-plate to prevent the SR end from separating from the plate. This arrangement improves the connection reliability between the wire and the plate, thereby ensuring a good fit between the waterproof section and the first mating groove, and allowing the waterproof rib to maintain stable pressure against the second mating groove, thus improving the stability of use.

[0014] According to another aspect of the embodiments of this application, an electronic device is provided that is both effectively waterproof and cost-effective. The electronic device includes a first housing, a second housing, and the aforementioned waterproof structure. The first housing is detachably connected to the first housing, and the first housing is connected to the second sub-board, both being integrally formed. The second housing is connected to the second sub-board, both being integrally formed, thereby enabling the first housing, the second housing, the first sub-board, the second sub-board, and the wires to collectively form a sealed chamber.

[0015] Specifically, an ultrasonic sealing strip is provided between the first housing and the second housing, and the ultrasonic sealing strip is used to seal the connection gap between the first housing and the second housing after being irradiated by ultrasound. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this application. Furthermore, the terms "first," "second," and "third" are used only for descriptive purposes such as distinguishing similar objects, and should not be construed as indicating or implying relative importance or order.

[0028] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0029] Please see Figures 1-3The waterproof structure 100 provided in this application embodiment includes a wire 110 and a plate 120. The wire 110 includes an SR end 111, and the SR end 111 includes a waterproof section 112. The waterproof section 112 is provided with a waterproof rib 113 that surrounds it in the circumferential direction. The waterproof rib 113 and the waterproof section 112 are integrally formed. The plate 120 includes a first sub-plate 121 and a second sub-plate 122, which are detachably connected. The first sub-plate 121 includes a first mounting groove 1211, and the second sub-plate 122 includes a second mounting groove 1221. The first mounting groove 1211 and the second mounting groove 1221 can be positioned and assembled into a positioning part. The positioning part includes a first mating groove 123 and a second mating groove 124. The waterproof section 112 can be engaged with the first mating groove 123 for positioning, and the waterproof rib 113 can be sealed with the second mating groove 124.

[0030] Further, please refer to Figures 1-3 The waterproof rib 113 is made of an elastic material, so the waterproof rib 113 and the second mating groove 124 are in elastic abutting contact, and the waterproof rib 113 and the second mating groove 124 are interference fit. This arrangement allows the waterproof rib 113 to always be in abutting contact with the second mating groove 124 to stably seal the gap between them, thereby effectively isolating moisture.

[0031] Further, please refer to Figures 1-3 The waterproof section 112 and the first mating groove 123 are fitted with zero clearance. This design facilitates the interception of slow-flowing seepage water or water vapor. It should be noted that zero clearance does not mean zero tolerance, but rather that the theoretical clearance is zero, while in reality there is a slight gap or slight interference. As a result, the interaction force between the waterproof section 112 and the first mating groove 123 is relatively small, making it suitable for blocking slow-flowing seepage water or water vapor.

[0032] Further, please refer to Figures 1-3 The SR end 111 also includes a locking groove 114, and the positioning part also includes a locking protrusion 125. The locking groove 114 can engage with the locking protrusion 125. This design facilitates further positioning of the SR end 111 and provides a buffer for water flow, thereby reducing water intrusion.

[0033] Further, please refer to Figures 1-3 Both sides of the waterproof section 112 are provided with engaging grooves 114, and both sides of the second mating groove 124 are provided with engaging protrusions 125. This arrangement makes the positioning of the SR end 111 more precise, thereby ensuring a good fit between the waterproof section 112 and the first mating groove 123, and allowing the waterproof rib 113 to maintain stable pressure against the second mating groove 124, thus improving the stability of use.

[0034] Further, please refer to Figures 1-3 The engaging groove 114 and engaging protrusion 125 are smoothly fitted together. This design facilitates the initial positioning and assembly of the SR end 111 of the wire 110 with the plate 120, thereby improving work efficiency.

[0035] Further, please refer to Figures 1-3 The positioning part is also provided with a filling strip 126, which is used to fill the gap between the SR end 111 and the positioning part after being irradiated by ultrasound. This arrangement can fill the tiny gaps between the SR end 111 and the positioning part, thereby preventing the entry of fine moisture.

[0036] Further, please refer to Figures 1-3 The SR end 111 facing the plate 120 is also provided with a locking terminal 115, which can simultaneously lock with the first sub-plate 121 and the second sub-plate 122 to prevent the SR end 111 from separating from the plate 120. This arrangement can improve the connection reliability between the wire 110 and the plate 120, thereby ensuring a good fit between the waterproof section 112 and the first mating groove 123, and ensuring that the waterproof rib 113 can maintain stable pressure against the second mating groove 124, thus improving the stability of use.

[0037] Please see Figures 4-7 The electronic device 200 provided in this application embodiment includes a first housing 210, a second housing 220 and the aforementioned waterproof structure 100. The first housing 210 and the second housing 220 are detachably connected. The first housing 210 is connected to the first sub-board 121 and the two are integrally formed. The second housing 220 is connected to the second sub-board 122 and the two are integrally formed, so that the first housing 210, the second housing 220, the first sub-board 121, the second sub-board 122 and the wire 110 together form a sealed chamber.

[0038] Further, please refer to Figures 4-7 An ultrasonic sealing strip 230 is provided between the first housing 210 and the second housing 220. The ultrasonic sealing strip 230 is used to seal the connection gap between the first housing 210 and the second housing 220 after being irradiated by ultrasound, thereby effectively waterproofing.

[0039] The following is a description of the assembly process of the electronic device 200 provided in this application.

[0040] When it is necessary to assemble the wire 110 and the plate 120 into a waterproof structure 100, the SR end 111 of the wire 110 is first positioned on the second sub-plate 122. Since the first sub-plate 121 and the second sub-plate 122 are not connected and fixed at this time, the second sub-plate 122 only has a part of the groove of the first mating groove 123. At this time, the waterproof section 112 on the SR end 111 is engaged with a part of the groove of the second mating groove 123 on the second sub-plate 122 for positioning. Then, the first sub-plate 121 is assembled onto the SR end 111. 1. The first sub-plate 121 is positioned and assembled by engaging a portion of the first mating groove 123 on the first sub-plate 121 with the waterproof section 112 on the SR end 111. Then, external force is applied to press the first sub-plate 121 and the second sub-plate 122 together, causing the waterproof rib 113 to press against the second mating groove 124. Finally, the waterproof structure 100 is sent into an ultrasonic device for ultrasonic treatment, which connects and fixes the first sub-plate 121 and the second sub-plate 122. At this time, the waterproof rib 113 is also pressed against the second mating groove 124 for sealing. At the same time, the filler strip 126 melts under the action of ultrasound and gradually fills the tiny gap between the SR end 111 and the positioning part for further sealing. The ultrasonic sealing strip 230 between the first housing 210 and the second housing 220 also melts, causing the first housing 210 and the second housing 220 to fuse together and seal the gap between them. After the ultrasonic treatment is completed, the assembly of the electronic device 200 is also completed.

[0041] Compared with the prior art, the waterproof structure 100 provided in this application provides a waterproof section 112 at the SR end 111 of the wire 110 to mate with the first mating groove 123 of the positioning part, and an integrally formed waterproof rib 113 on the waterproof section 112 to seal with the second mating groove 124 of the positioning part. This not only positions the SR end 111 of the wire 110 but also seals the space between the SR end 111 and the second mating groove 124 for waterproofing. The integral structure of the waterproof rib 113 and the waterproof section 112 reduces the assembly step of manually installing the waterproof rib 113 onto the waterproof section 112, improving work efficiency and saving labor costs. Furthermore, since there is no need to assemble the waterproof rib 113 with the waterproof section 112, this also avoids deformation of the core wire terminals of the wire 110 due to contact with the waterproof rib 113, thus preventing defects in the wire 110 during assembly and further saving costs. Therefore, the waterproof structure 100 provided in this application can effectively waterproof while effectively saving costs.

[0042] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
