DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0024] The specific implementation of the embodiments of the present specification is further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the embodiments of the present specification, but are not used to limit the scope of the embodiments of the present specification.

[0025] Figure 1 It is a structural schematic diagram of the wire-crossing waterproof structure shown in some embodiments of this specification. Figure 2 It is an exploded view of the wire-crossing waterproof structure shown in some embodiments of this specification.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the wire-passing waterproof structure includes a waterproof shell 100, a pressure plate 200 and a flexible waterproof plug 300; the waterproof shell 100 is provided with a groove 110 for accommodating the waterproof plug 300 and a receiving cavity 120 for accommodating a plurality of joints, the groove 110 is communicated with the receiving cavity 120, and the pressure plate 200 presses and fixes the waterproof plug 300 in the groove 110; the waterproof plug 300 includes a first component 311 and a second component 312, and a plurality of wire-passing holes 320 are provided between the first component 311 and the second component 312; a plurality of through grooves 210 are provided on the pressure plate 200.

[0027] By providing a wire-passing waterproof structure with a split waterproof plug 300, after the cable passes through the wire-passing hole 320, the split waterproof plug 300 can be inserted into the groove 110 and tightly clamp the cable, while ensuring the waterproof ability of the wire-passing waterproof structure.

[0028] The waterproof housing 100 is the main structure of the over-line waterproof structure, which can accommodate the connector of the cable to prevent the connector of the cable from being splashed with water and causing a short circuit. In some embodiments, the waterproof housing 100 can be a hollow box-shaped object. The waterproof housing 100 can be in a variety of shapes, for example, the waterproof housing 100 can be in a cubic shape or a hemispherical shape. In some embodiments, the waterproof housing 100 can be in a prism shape, and its larger side surface can be used to fix it on a wall or a certain plane of the device. The prism-shaped waterproof housing 100 is more stable after installation and is not easy to fall off from a fixed position when it is impacted from the side.

[0029] In some embodiments, the waterproof housing 100 further includes a back plate, which is disposed on a side of the waterproof housing 100 away from the groove 110. The waterproof housing 100 and its back plate form a receiving cavity 120. A through hole is provided on the back plate, through which the plug portion of the connector passes, so that the connector can be connected to a connector of an external device. In some embodiments, the waterproof housing 100 may also not include a back plate, and a side of the waterproof housing 100 away from the groove 110 may be connected to a wall or a plane of a device. The waterproof housing 100 can form a receiving cavity 120 with a wall or a plane of a device to receive the connector therein, and the connector can be connected to a wiring connector in the wall or a line connector of the device.

[0030] In some embodiments, a plurality of cables connected to the connector pass through a plurality of cable holes 320 and a plurality of through slots 210 .

[0031] In some embodiments, the wire 400 may include a connector and a cable connected to the connector. The connector includes a plug portion, which can be inserted into a corresponding jack to electrically connect the wire 400 to other wires or devices. The plug portion can be a male connector or a female connector. In some embodiments, the end portion is provided at one end of the connector, and the cable is connected to the other end of the connector.

[0032] In some embodiments, the number of the wire holes 320 is the same as the number of the through slots 210. Each connector in the wire waterproof structure is connected to a cable, and the cable can pass through a wire hole 320 and a through slot 210 in sequence.

[0033] In some embodiments, the wire hole 320 is arranged corresponding to the position of the through groove 210. When multiple connectors are accommodated in the wire waterproof structure, the cable corresponding to each connector can pass through the wire hole 320 and the through groove 210 at the corresponding position, so that the cables are arranged neatly and beautifully.

[0034] Figure 3 It is a cross-sectional view of the wire-crossing waterproof structure shown in some embodiments of this specification. Figure 4 Some embodiments of this specification are shown in Figure 3 Magnified view of area A.

[0035] In some embodiments, along the extension direction of the groove 110 , the inner side wall of the groove 110 has a first taper and a second taper respectively, and the first taper is greater than the second taper, so that the opening of the groove 110 close to the accommodating cavity 120 is smaller than the opening away from the accommodating cavity 120 .

[0036] For example, Figure 3 and Figure 4 As shown, the groove 110 may include a first side wall 111 and a second side wall 112 , wherein the first side wall 111 is close to the accommodating cavity 120 and has a first taper, and the second side wall 112 is away from the accommodating cavity 120 and has a second taper.

[0037] By providing the groove 110 with the first and second tapers of the inner side wall, firstly, when the waterproof plug 300 is inserted into the groove 110, the force exerted on the waterproof plug 300 by the inner wall of the groove 110 will gradually increase, and finally the waterproof plug 300 and the groove 110 will be interference fit. The interference fit between the waterproof plug 300 and the groove 110 can prevent water from entering the waterproof housing 100 from between the waterproof plug 300 and the inner wall of the groove 110, thereby enhancing the waterproof capability of the wire-passing waterproof structure; secondly, when the force exerted on the waterproof plug 300 by the inner wall of the groove 110 gradually increases, the force exerted by the outer wall of the waterproof plug 300 inwards will also be transmitted to the wire-passing hole 320 between the first component 311 and the second component 312, thereby causing the wire-passing hole 320 to shrink, thereby tightly clamping the cable in the wire-passing hole 320, thereby fixing the cable and preventing water from seeping between the cable and the inner wall of the wire-passing hole 320, thereby enhancing the waterproof capability of the wire-passing waterproof structure.

[0038] Figure 5 It is a schematic diagram of the structure of the waterproof plug shown in some embodiments of this specification.

[0039] like Figure 5 As shown, the waterproof plug 300 is a plug head for passing the line and waterproofing. The waterproof plug 300 can be made of a variety of flexible materials, such as silicone, rubber, etc.

[0040] In some embodiments, the waterproof plug 300 includes a first member 331 and a second member 332, and the first member 331 and the second member 332 overlap along the thickness direction of the waterproof plug 300. In some embodiments, the first member 331 and the second member 332 can be fixedly connected by bonding, snap connection, etc. In some embodiments, the first member 331 and the second member 332 can be integrally formed.

[0041] In some embodiments, the outer sidewall of the first member 331 has a third taper matching the first taper, and the outer sidewall of the second member 332 has a fourth taper matching the second taper.

[0042] The first component 331 and the second component 332 respectively have a taper matching the groove, which can make the outer wall of the waterproof plug 300 and the inner wall of the groove 110 match. After the waterproof plug 300 is inserted into the groove 110, the tapered inner wall of the groove 110 can convert the force of pressing the waterproof plug 300 toward the groove 110 into a force directed toward the wire hole 320 by the outer wall of the waterproof plug 300, thereby fully shrinking the wire hole 320 and clamping the cable in the wire hole 320.

[0043] In some embodiments, the third taper may be less than or equal to the first taper, and the fourth taper may be less than or equal to the second taper, so that after the waterproof plug 300 is inserted into the groove 110, the waterproof plug 300 can have an interference fit with the groove 110 to enhance the waterproof capability.

[0044] In some embodiments, the waterproof plug 300 includes a third member 350, the third member 350 and the second member 332 overlap along the thickness direction of the waterproof plug 300, and the third member 350 abuts against the pressing plate 200. When the waterproof plug 300 is installed in the groove, one side of the third member 350 can abut against the pressing plate 200, and the edge of the other side of the third member 350 can abut against the edge of the groove, thereby preventing the waterproof plug 300 from being excessively squeezed into the accommodating cavity 120, resulting in waterproof failure; in addition, it is also convenient to disassemble and remove the waterproof plug 300, so that the number of joints in the over-line waterproof structure can be increased or decreased at any time.

[0045] In some embodiments, along the width direction of the waterproof plug 300, the waterproof plug 300 can be divided into a first component 311 and a second component 312. The first component 311 and the second component 312 are in contact with each other but not connected. The contact surface between the first component 311 and the second component 312 passes through a plurality of wire holes 320, so that the first component 311 and the second component 312 can open all the wire holes 320 when separated, and can be enclosed into a plurality of wire holes 320 when closed.

[0046] Figure 6 Some embodiments of this specification are shown in Figure 5 Magnified view of area B.

[0047] like Figure 6As shown, in some embodiments, an engagement structure is provided between the first component 311 and the second component 312. For example, a plurality of engagement grooves 341 are provided on one side of the first component 311 facing the second component 312, and the extending direction of the engagement grooves 341 is perpendicular to the axial direction of the wire hole 320, and a plurality of engagement protrusions 342 are correspondingly provided on one side of the second component 312 facing the first component 311, and the engagement grooves 341 are engaged with the engagement protrusions 342 when the first component 311 and the second component 312 are closed.

[0048] By providing the meshing structure, the contact area between the first component 311 and the second component 312 is increased when they are closed. If water passes through the contact surface between the first component 311 and the second component 312, the larger contact area will increase the penetration distance of water from one side of the waterproof plug 300 to the other side. Therefore, by providing the meshing structure, the difficulty of water penetration is increased, thereby improving the waterproof performance of the waterproof plug 300.

[0049] In some embodiments, the first component 311 and the second component 312 of the waterproof plug 300 may be connected via a flexible connector 360 , and the flexible connector 360 may be made of a flexible material such as rubber or silicone.

[0050] In some embodiments, one end of the flexible connector 360 is connected to the side of the first component 311 facing the waterproof housing 100, and the other end of the flexible connector 360 is connected to the side of the second component 312 facing the waterproof housing 100. In some embodiments, there may be multiple flexible connectors 360.

[0051] In some embodiments, at least one waterproof ring 370 may be provided inside the wire hole 320, and the waterproof ring 370 may be made of a flexible material. The waterproof ring 370 may be provided to further enhance the waterproof capability between the cable and the wire hole 320.

[0052] In some embodiments, the waterproof plug 300 includes a plurality of blocking members 380, which are matched with the plurality of wire holes 320 respectively, and the plurality of blocking members 380 can detachably close the plurality of wire holes 320. When one or more wire holes 320 do not have cables passing through, the blocking members 380 can be inserted to block the wire holes 320 to ensure the waterproof capability of the wire waterproof structure.

[0053] The pressing plate 200 is a component that cooperates with the waterproof housing 100 to clamp the waterproof plug 300 therein to fix the waterproof plug 300. The through slot 210 provided on the pressing plate 200 can be used for cables to pass through. The pressing plate 200 can be made of flexible materials, such as silicone, rubber, etc.

[0054] In some embodiments, one end of the plurality of through slots 210 extends to the same side of the pressure plate 200 , so that after the cable passes through the wire hole 320 , the pressure plate 200 can be inserted from one side of the cable and fixedly connected to the waterproof housing 100 .

[0055] In some embodiments, the pressing plate 200 and the waterproof housing 100 are detachably connected. The pressing plate 200 and the waterproof housing 100 can be connected in various ways, such as buckle connection or fastener connection.

[0056] In some embodiments, the pressing plate 200 can cover the side of the waterproof plug 300 away from the waterproof housing 100 , so as to completely press the waterproof plug 300 against the waterproof housing 100 .

[0057] In some embodiments, screw holes 220 may be provided at corresponding positions on the pressing plate 200 and the waterproof housing 100 , and screws may be inserted into the screw holes 220 to fix the pressing plate 200 and the waterproof housing 100 together.

[0058] For example, when the wire 400 needs to be installed, first pass the cable of the wire 400 through the wire hole 320 in the waterproof plug 300, then pass the connector of the wire 400 through the groove 110 of the waterproof housing 100, and install the connector in the accommodating cavity 120 of the waterproof housing 100, then close the first part 311 and the second part 312 of the waterproof plug 300, bury the cable in the wire hole 320 of the waterproof plug 300, and then insert the waterproof plug 300 into the groove 110 of the waterproof housing 100. Finally, place the pressing plate 200 on the outer end surface of the waterproof plug 300 and lock the screws.

[0059] By installing the wire 400 in this way, the wire 400 can be stably and quickly installed in the wire-passing waterproof structure while maintaining good waterproof capability of the wire-passing waterproof structure.
