[0038] In the description of the present application, the meaning of several is more than one, the meaning of multiple is more than two, greater than, less than, exceeding, etc. are understood as not including the present number, and above, below, within, etc. are understood as including the present number. If the first and second are described only for the purpose of distinguishing technical features, they should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or the sequence of the indicated technical features.

[0039] In the description of this application, unless otherwise clearly defined, terms such as "setting", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in this application in combination with the specific content of the technical solution.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0041] In household appliances, electronic appliances, or intelligent control devices, the device generally has conductive wires or signal wires connected, or both conductive wires and signal wires at the same time. One end of the conductive wire or signal wire extends into the device body, and the other end extends outside the device body, with a small length reserved, and the lead-out wire at the outside end of the body has a connection terminal or a mating connector, as Figure 1 shown. When this device is connected to an external power source or a controlled device, this device can work and play a role in the controlled device, and the connection between this master device and the controlled device requires continuous connection between the two. When the master device and the controlled device are subjected to external forces, it is easy for the connection joint of the master device and the connection joint of the controlled device to be disconnected, resulting in the interruption of the connection between the two. Therefore, it is necessary to perform anti-pulling treatment on the connection joints of the two to maintain the effective connection between the master device and the controlled device.

[0042] In view of this, an embodiment of this application on the one hand provides a wire anti-pulling device, which can effectively realize the wire anti-pulling function.

[0043] See Figures 2 to 5 As shown, the wire anti-pulling device of an embodiment of this application on the one hand includes a wire clamping device 200. The wire clamping device 200 includes a substrate 210. The substrate 210 is provided with at least one first wire clamping groove 211. The first wire clamping groove 211 is recessed from the outer edge 213 of the substrate 210 towards the inside of the substrate 210. The first wire clamping groove 211 penetrates through the substrate 210. The first wire clamping groove 211 is used for a cable to pass through.

[0044] Among them, the first electrical appliance 100 includes a first body, a mounting plate 110, and a first cable 120. The mounting plate 110 is disposed on the side of the first body. One end of the first cable 120 is connected to the first body, and the other end of the first cable 120 has a first connector 121. The second electrical appliance 300 includes a second cable 310. The second cable 310 has a second connector 311. The second connector 311 is cooperatively connected with the first connector 121, and the second connector 311 is disposed inside the mounting plate 110. The diameter of the second cable 310 is smaller than the diameter of the cross-section of the second connector 311. The first cable slot 211 in the substrate 210 is used for the cable to pass through, so that the cable inside the first body can be connected to an external device. It should be understood that there is a cavity inside the first body, and the second connector 311 in both the first cable 120 and the second cable 310 is disposed inside the first body.

[0045] During application, the wire clamping device 200 is fixedly connected to the mounting plate 110 of the first electrical appliance, and the cable is clamped in the first cable slot 211 of the wire clamping device 200. Among them, the cross-section of the second connector is larger than the cross-sectional area of the first cable slot 211, so that the second connector cannot pass through the first cable slot 211. Therefore, when the second cable 310 is dragged, the first cable slot 211 can block the second connector to prevent the second cable 310 from being continuously dragged, thereby preventing the second connector and the first connector 121 from being disconnected, and further realizing the anti-pulling function of the wire.

[0046] In some embodiments, please continue to refer to as Figure 2 shown, the substrate 210 is further provided with a second cable slot 212, and the second cable slot 212 is recessed from the outer edge 213 of the substrate 210 towards the inside of the substrate 210. It should be understood that the inside of the substrate 210 refers to the geometric center of the substrate 210.

[0047] In some embodiments, please continue to refer to as Figure 2 shown, the wire clamping device 200 includes a limiting plate 220 fixedly connected to the substrate 210 at one end, and the limiting plate 220 has a protrusion 221. During installation, the protrusion 221 can play a role in limiting and fixing, restricting the mounting plate 110 between the substrate 210 and the protrusion 221, thereby realizing the installation and fixation of the wire clamping device 200 to the mounting plate 110.

[0048] In some embodiments, please continue to refer to as Figure 2 shown, the wire clamping device 200 further includes a guiding plate 230 fixedly connected to the substrate 210 at one end. The guiding plate 230 is disposed on one side of the limiting plate 220, and there is a gap 240 between the limiting plate 220 and the guiding plate 230. This gap 240 can provide space for the offset of the limiting plate 220, facilitating the mounting plate 110 to disengage from the engaging relationship with the protrusion 221, and further realizing the disassembly of the wire clamping device 200.

[0049] In some embodiments, please continue to refer to Figure 2 As shown, the guide plate 230 includes a first guiding portion 231, a clamping portion 232, and a second guiding portion 233. The clamping portion 232 is U-shaped. The first guiding portion 231 is fixedly connected to one side of the clamping portion 232, and the second guiding portion 233 is fixedly connected to the other side of the clamping portion 232. The first guiding portion 231, the clamping portion 232, and the second guiding portion 233 define a first wire clamping groove 211. Further, the clamping portion 232 has a limiting notch 2321 located at one end of the clamping portion 232 away from the substrate 210. The limiting notch 2321 is used to abut against the second connector 311, and at the same time, the limiting notch 2321 can position the second connector 311.

[0050] In some embodiments, refer to Figure 2 As shown, the substrate 210 is provided with a first through hole 214, and the protrusion 221 is located in the extending direction of the first through hole 214. When disassembling the wire clamping device 200, a tool is used to pry the mounting plate 110 clamped between the protrusion 221 and the substrate from the first through hole 214, and the quick disassembly and assembly of the wire clamping device 200 can be realized.

[0051] Refer to Figures 2 to 12 , another embodiment of the present application discloses a device with a function of preventing wire pulling, which includes a first electrical appliance 100, a wire pulling prevention device, and a second electrical appliance 300.

[0052] Specifically, the first electrical appliance 100 includes a first body, a mounting plate 110, and a first cable 120. The mounting plate 110 is disposed on the side surface of the first body. The mounting plate 110 is provided with a mounting port 111 for mounting and fixing the wire clamping device 200. One end of the first cable 120 is connected to the first body, and the other end of the first cable 120 has a first connector 121; the second electrical appliance 300 includes a second cable 310, the second cable 310 has a second connector 311, the second connector 311 is cooperatively connected with the first connector 121, and the second connector 311 is disposed inside the mounting plate 110. The diameter of the second cable 310 is smaller than the cross-sectional diameter of the second connector 311; the wire clamping device 200 includes a substrate 210, and the substrate 210 is provided with a first wire clamping groove 211 for a cable to pass through so that the cable inside the first body can be connected to an external device.

[0053] It should be understood that the interior of the first body has a cavity, and the second connector 311 in the first cable 120 and the second cable 310 are both arranged inside the first body; the length of the first cable 120 is L, and the distance from the connection end of the first body for connecting with the first cable 120 to the inner end of the first cable slot 211 is s, satisfying that L is greater than or equal to s, so as to prevent the second connector 311 from being disconnected from the first connector 121 before it abuts against the first cable slot 211.

[0054] Wherein, the maximum diameter of the circumscribed circle of the cross-sectional profile of the second connector 311 is d, and the diameter of the inscribed circle of the cross-sectional profile of the first cable slot 211 is D, satisfying that d is greater than D, that is to say, the second connector 311 cannot pass through the first cable slot 211.

[0055] In some embodiments, the cable gripper 200 is fixedly connected to the mounting plate 110, and the cable is stuck in the first cable slot 211 of the cable gripper 200. Since the cross-section of the second connector 311 is larger than the cross-sectional area of the first cable slot 211, the second connector 311 cannot pass through the first cable slot 211. Therefore, when dragging the second cable 310, the first cable slot 211 can stop the second connector 311, so as to avoid the second cable 310 from being continuously dragged, thereby preventing the second connector 311 and the first connector 121 from being disconnected, and further realizing the anti-pulling function of the wire.

[0056] In this embodiment, the first connector 121 is a male connector, and the second connector 311 is a female connector, and the male connector matches the female connector. It should be understood that in some other embodiments, the first connector 121 can be selected as a female connector or other wiring terminals, and the second connector 311 matches the first connector 121.

[0057] In some embodiments, as shown in Figures 2 to 5 the substrate 210 is further provided with a second cable slot 212. Both the first cable slot 211 and the second cable slot 212 are recessed from the outer edge 213 of the substrate 210 towards the inside of the substrate 210. Correspondingly, the first electrical appliance 100 includes a first cable 120 and a fourth cable 130. One end of the fourth cable 130 is electrically connected to the first body, and the other end is a fourth connector 131. The device with the anti-pulling function of the wire further includes a third electrical appliance 400. The third electrical appliance 400 includes a third cable 410. The third cable 410 is snapped into the second cable slot 212, and the third connector 411 in the third cable 410 is connected to the fourth connector 131 of the fourth cable 130 inside the first body.

[0058] Among them, the cross-sectional area of the third cable 410 is larger than that of the third joint 411, and the second joint 311 and the third joint 411 are located inside the substrate 210. It should be noted that the cross-sectional area of the third joint 411 is larger than that of the second cable slot 212, that is to say, the third joint 411 cannot pass through the second cable slot 212.

[0059] During use, since the second joint 311 cannot pass through the first cable slot 211, when the second cable 310 is dragged, the second joint 311 abuts against the inner end of the first cable slot 211 and then stops moving relative to the mounting plate 110, so that the first joint 121 and the second joint 311 remain effectively connected, thus realizing the anti-pulling function. Similarly, in the above structure, the third joint 411 can also always be effectively connected to the fourth joint 131, thus realizing the anti-pulling function.

[0060] As one of the embodiments, the third cable 410 and the fourth cable 130 are connected by male and female joints, and the third cable 410 is arranged in the second cable slot 212.

[0061] In some embodiments, please continue to refer to Figure 2 and Figure 12 As shown, the cable clamp 200 includes a limiting plate 220 fixedly connected to the substrate 210 at one end. The limiting plate 220 has a protrusion 221, and the mounting plate 110 has a mounting portion 112 matching the protrusion 221. During assembly, the mounting portion 112 is located between the substrate 210 and the protrusion 221. Further, referring to Figure 2 As shown, the end face of the protrusion 221 close to the substrate 210 is parallel to the end face of the substrate 210. During operation, this end face of the protrusion 221 abuts against the mounting portion 112; the side of the protrusion 221 away from the end face of the substrate 210 is an inclined surface, which can facilitate the mounting portion 112 to slide into the space between the protrusion 221 and the substrate 210, so as to install the cable clamp 200 on the mounting plate 110.

[0062] In some embodiments, please continue to refer to Figure 2 As shown, the substrate 210 is provided with a first through hole 214, and the protrusion 221 is located in the extending direction of the first through hole 214. When disassembling the cable clamp 200, a tool can be used to pry the mounting portion 112 of the mounting plate 110 from the first through hole 214, so that the mounting portion 112 is disengaged from the protrusion 221 to improve the disassembly efficiency.

[0063] In some embodiments, the substrate 210 is provided with a fastening hole 215, the mounting plate 110 is provided with a mounting hole 113, the position of the mounting hole 113 corresponds to the position of the fastening hole 215, and a fastener is passed through the fastening hole 215 and the mounting hole 113. In this embodiment, the fastener is selected as a screw.

[0064] In some embodiments, please continue to refer to Figure 2 and Figure 9 As shown, the wire clamping device 200 further includes a guide plate 230 fixedly connected to one end of the substrate 210. The guide plate 230 is disposed on one side of the limiting plate 220, and there is a gap 240 between the limiting plate 220 and the guide plate 230.

[0065] As can be seen from the figure, the contour of the installation port 111 in the installation plate 110 is polygonal, and the sides of the polygon are connected by arcs. The outer contour defined by the limiting plate 220 and the guide plate 230 matches the contour of the installation port 111 in the installation plate 110. Among them, the edge of the guide plate 230 is a bending portion 2331, and the bending portion 2331 matches the arc surface of the installation port 111. The setting of the guide plate 230 enables the wire clamping device 200 to be fully abutted against the installation port 111, effectively avoiding the loosening of the wire clamping device 200. There is a gap between the guide plate 230 and the limiting plate 220, which facilitates one end of the limiting plate 220 to shift towards the middle of the wire clamping device 200, so that the installation portion 112 is disengaged from the limit of the protrusion 221, enabling the wire clamping device 200 to be smoothly disassembled from the installation plate 110.

[0066] In some embodiments, please continue to refer to Figure 2 As shown, the guide plate 230 includes a first guiding portion 231, a clamping portion 232 and a second guiding portion 233. The clamping portion 232 is U-shaped. The first guiding portion 231 is fixedly connected to one side of the clamping portion 232, and the second guiding portion 233 is fixedly connected to the other side of the clamping portion 232. The first guiding portion 231, the clamping portion 232 and the second guiding portion 233 define a first wire slot 211. It should be noted that there is a groove in the clamping portion 232, and the groove is located in the extending direction of the first wire slot 211, jointly forming the first wire slot 211. As can be seen from the figure, the first wire slot 211 extends a certain length in the direction away from the substrate 210, thereby increasing the contact area between the first wire slot 211 and the second cable 310, and can effectively fix and protect the second cable 310.

[0067] In some embodiments, refer to Figure 7 and Figure 8 As shown, the clamping portion 232 has a limiting notch 2321. The limiting notch 2321 is located at one end of the clamping portion 232 away from the substrate 210, and the limiting notch 2321 is used to abut against the second connector 311. Among them, one end of the second connector 311 close to the wire clamping device 200 is frustum-shaped, and the second connector 311 has an inclined surface. The second cable 310 is subjected to an external force along the length direction of the second cable 310, so that when the second connector 311 abuts against the wire clamping device 200, the limiting notch 2321 abuts against the inclined surface of the second connector 311.

[0068] The second aspect of the present application discloses an application method of a wire anti-pulling structure, which is used to install the above-mentioned device with wire anti-pulling function, and further includes the following steps: Connect the first joint 121 and the second joint 311; Snap the second cable 310 into the first cable slot 211, and make the second joint 311 located inside the mounting plate 110; Install the cable clamp 200 on the mounting port 111 of the mounting plate 110.

[0069] The above has described the embodiments of the present application in detail with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
