[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Please refer to Figures 1 to 15 , Figure 1 An exploded view of a signal protection device provided by an embodiment of the present application; Figure 2 A schematic diagram of the structure of a porous waterproof ring provided in an embodiment of the present application;

[0042] Please refer to Figures 1 to 5 The present application provides a signal protection device, including a shell 1, a porous waterproof ring 2 and a plurality of plug rods 3, all of which are arranged in the shell 1; in the signal protection device, a plurality of through holes 21 are arranged in the porous waterproof ring 2, any one of which passes through the porous waterproof ring 2 along the axial direction, and all of the plug rods 3 are respectively inserted into the plurality of through holes 21 of the porous waterproof ring 2; in the signal protection device, a plurality of slits 22 are arranged on the circumferential side of the porous waterproof ring 2, any one of which passes through from the surface of the porous waterproof ring 2 to the corresponding through hole 21, and all of the slits 22 and all of the through holes 21 are opposite to each other.

[0043] In this embodiment, a slit 22 is provided on the circumferential side of the porous waterproof ring 2, and the slit 22 penetrates from the surface of the porous waterproof ring 2 to the corresponding through hole 21, so that the through hole 21 is not only exposed to the axial ends of the porous waterproof ring 2, but also exposed from the slit 22 to the outer periphery of the porous waterproof ring 2. The slit width of the slit 22 can be flexibly set according to the material and size of the porous waterproof ring 2 and the material and size of the plug rod 3. Usually, the slit width of the slit 22 is significantly smaller than the diameter of the plug rod 3, so as to prevent the plug rod 3 from accidentally falling off from the side opening of the slit 22.

[0044] The slits 22 are arranged on the peripheral side of the porous waterproof ring 2, which can not only appropriately increase the elasticity of the through hole 21 and reduce the difficulty of installing and removing the plug rod 3 in the through hole 21, but also increase the entrance and exit of the through hole 21, making it convenient for the plug rod 3, wires and other components to be inserted into the through hole 21 through the slits 22, so that the plug rod 3 can enter and exit the porous waterproof ring 2 from the side of the porous waterproof ring 2, and is also conducive to squeezing the porous waterproof ring 2, so that the porous waterproof ring 2 produces a larger compression amount, which facilitates the porous waterproof ring 2 to be inserted into the outer shell 1.

[0045] It can be seen that the signal protection device provided in the present application optimizes the shape structure of the porous waterproof ring 2, and improves the installation characteristics of the porous waterproof ring 2 and related components by adding a slit 22 to the porous waterproof ring 2. This can not only reduce the installation difficulty of the porous waterproof ring 2 and related components and improve the installation efficiency, but also help to reduce the restrictions on the shape and size of the porous waterproof ring 2.

[0046] The signal protection device provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0047] In some embodiments, the slits 22 are specifically oblique slits 22 provided on the porous waterproof ring 2. For example, for any slit 22, the slit 22 passes through from the surface of the porous waterproof ring 2 to the corresponding through hole 21. At the same time, the extension path of the slit 22 along any cross section of the porous waterproof ring 2 is inclined to the diameter of the porous waterproof ring 2, so it can be regarded as an oblique slit 22. A porous waterproof ring 2 is provided with a plurality of slits 22, which are arranged around the porous waterproof ring 2. Usually, these slits 22 are inclined in the same direction and at the same angle along the circumference of the porous waterproof ring 2. For example, these slits 22 are all inclined at the same angle in the clockwise direction of the porous waterproof ring 2.

[0048] The oblique slits 22 provided on the circumferential side of the porous waterproof ring 2 are conducive to improving the disassembly and assembly performance of the plug rod 3 and the porous waterproof ring 2. This is reflected in that when the plug rod 3 enters and exits the oblique slits 22, it can be rotated and pressed in and out along the direction of all the oblique slits 22, which is not only conducive to the operator to apply pressure to the plug rod 3, but also can make use of the difference in wall thickness of the porous waterproof ring 2 on both sides of the oblique slits 22 to allow the plug rod 3 to enter and exit the oblique slits 22. In addition, compared with the slits 22 that penetrate along the diameter direction of the porous waterproof ring 2, the oblique slits 22 provided in the porous waterproof ring 2 of limited size can extend the length of the slits 22, thereby preventing the plug rod 3 from accidentally escaping from the oblique slits 22 under the action of external forces. Among them, the length of the slits 22 refers to the size of the slits 22 in the radial direction of the porous waterproof ring 2.

[0049] For reference Figure 2 and Figure 3 The porous waterproof ring 2 is provided with a plurality of through holes 21 and a plurality of slits 22. Usually, all the through holes 21 are arranged in a circle around the central axis of the porous waterproof ring 2. Therefore, the distances from each through hole 21 to the outer surface of the porous waterproof ring 2 are equal, and the angles between adjacent through holes 21 are equal.

[0050] For reference Figure 3 and Figure 4 In order to improve the installation effect of the porous waterproof ring 2 and the shell 1, a first positioning groove 4 and a first positioning protrusion 5 are provided between the porous waterproof ring 2 and the shell 1; the first positioning groove 4 and the first positioning protrusion 5 are provided between the contact surfaces of the shell 1 and the porous waterproof ring 2. For example, the first positioning groove 4 is provided on the outer surface of the porous waterproof ring 2, and the first positioning protrusion 5 is provided on the inner wall of the shell 1. When the porous waterproof ring 2 is installed into the shell 1, the outer wall of the porous waterproof ring 2 is close to the inner wall of the shell 1. Once the porous waterproof ring 2 is inserted into the shell 1, the first positioning groove 4 and the first positioning protrusion 5 are embedded in the concave and convex parts, so that the porous waterproof ring 2 and the shell 1 can be positioned axially, and the porous waterproof ring 2 can be limited along the shell 1. Figure 2 The porous waterproof ring 2 moves in the up and down directions to ensure the installation position of the porous waterproof ring 2 in the shell 1.

[0051] For reference Figure 1 , Figures 6 to 9In some embodiments, the housing 1 of the signal protection device may include a nut 11, a cylindrical shell 12 and a base 13; the nut 11 and the base 13 are respectively arranged at the axial ends of the cylindrical shell 12, and both the nut 11 and the base 13 are sealed and connected to the axial end of the cylindrical shell 12; a first gasket 6 is provided between the cylindrical shell 12 and the base 13, and a second gasket 7 is provided on the bottom end surface of the base 13. The first gasket 6 is interference-fitted between the cylindrical shell 12 and the base 13 to seal the cylindrical shell 12 and the base 13. Part of the gasket structure of the second gasket 7 is interference-extruded in the base 13, and the rest of the gasket structure is outside the base 13. The part of the gasket structure outside the base 13 fits the bottom end surface of the base 13.

[0052] In the above embodiment, the first gasket 6 and the second gasket 7 are used to seal different parts of the housing 1 respectively, which can improve the sealing effect of the housing 1 on the electrical parts installed therein.

[0053] In the above embodiments, reference may be made to Figure 8 and Fig.12 The first gasket 6 can be specifically configured as a toothed gasket, the inner periphery of the toothed gasket is free from smoothness, and the outer periphery of the toothed gasket is provided with a plurality of teeth, and these teeth surround the first gasket 6. The toothed gasket is named because the outer periphery is provided with teeth, and the toothed gasket improves the sealing effect of the cylindrical shell 12 and the base 13 because the outer periphery is provided with teeth.

[0054] The sealing effect of the toothed gasket on both the cylindrical shell 12 and the base 13 is mainly reflected in that it can improve the installation interference between the cylindrical shell 12 and the base 13, and can use the grooves between adjacent teeth to accumulate water and dust, and effectively remove the water and dust accumulated in the aforementioned grooves when the first gasket 6 is removed.

[0055] In the above embodiments, reference may be made to Figure 8 The second gasket 7 is provided with a first annular protrusion 71 and a second annular protrusion 72 for being inserted from the bottom surface of the base 13, and the first annular protrusion 71 and the second annular protrusion 72 extend in different directions of the base 13; correspondingly, the base 13 is provided with a first annular groove and a second annular groove, and the first annular groove can be used for the first annular protrusion 71 to be embedded therein, and the second annular groove can be used for the second annular protrusion 72 to be embedded therein, and the aforementioned first annular groove and the second annular groove both extend inward from the bottom end surface of the base 13, and extend in different directions of the base 13 respectively.

[0056] When assembling the base 13 and the above-mentioned second gasket 7, the first annular groove and the second annular groove are respectively inserted and connected with the first annular protrusion 71 and the second annular protrusion 72, which can not only increase the contact area between the second gasket 7 and the base 13, but also enrich the force form between the second gasket 7 and the base 13, thereby ensuring the connection strength between the second gasket 7 and the base 13.

[0057] It can be seen that the above-mentioned first gasket 6 is a toothed gasket, which can be made of rubber material and is installed with interference fit on the base 13 and the shell respectively to increase the sealing and waterproof properties; the different bosses of the above-mentioned second gasket 7 and the various annular grooves of the base 13 are inserted and installed with interference fit to increase the sealing and waterproof properties.

[0058] For reference Figure 8 , Fig.10 , Fig.11 In some embodiments, an elastic buckle 8 is provided on the outside of the cylindrical shell 12, and at the same time, a buckle mounting portion is provided inside the base 13; the aforementioned elastic buckle 8 includes a root 81 and a head 82, the root 81 is connected to the cylindrical shell 12, and the head 82 expands outward toward the circumference of the cylindrical shell 12. When the cylindrical shell 12 and the base 13 are assembled, the part of the elastic buckle 8 close to the root 81 can be squeezed and inserted into the buckle mounting portion.

[0059] For the elastic buckle 8, its root 81 is connected to the cylindrical shell 12 and the head 82 is separated from the cylindrical shell 12, and the head 82 is expanded outward relative to the cylindrical shell 12, so the operator can easily and conveniently press the head 82 of the elastic buckle 8, and pressing the head 82 of the elastic buckle 8 will also cause the root 81 of the elastic buckle 8 to deform accordingly. For example, when the head 82 of the elastic buckle 8 is pressed toward the cylindrical shell 12, the root 81 of the elastic buckle 8 is also moved closer to the cylindrical shell 12, which is conducive to the insertion of the root 81 of the elastic buckle 8 into the buckle installation part, and of course, it is also conducive to the extraction of the root 81 of the elastic buckle 8 from the buckle installation part. When the squeezing force applied to the head 82 of the elastic buckle 8 is cancelled, the elastic buckle 8 is reset under its own elasticity.

[0060] In some embodiments, reference may be made to Figure 6 , Figure 8 , Fig.10 , Fig.11 and Fig.14 The elastic buckle 8 is provided with a second positioning protrusion 9. At the same time, the buckle mounting portion is provided with a second positioning groove 10 for being concavely and convexly engaged with the second positioning protrusion 9. When assembling the cylindrical shell 12 and the base 13, the part of the elastic buckle 8 near the root 81 is gradually squeezed and inserted into the buckle mounting portion. Once the elastic buckle 8 is inserted into the buckle mounting portion, the second positioning protrusion 9 and the second positioning groove 10 are concavely and convexly engaged with each other, so that the cylindrical shell 12 and the base 13 can be positioned and connected along the axial direction of the cylindrical shell 12. Figure 8 and Fig.14 The second positioning groove 10 can be specifically configured as a rectangular through hole 21, and correspondingly, the second positioning protrusion 9 is in the shape of a rectangular prism.

[0061] For reference Fig.11 The second positioning protrusion 9 of the above embodiment may include a limiting plane 91 and a transition arc surface 92; the limiting plane 91 and the transition arc surface 92 are sequentially distributed along the insertion direction of the elastic buckle 8. In other words, along the insertion direction of the elastic buckle 8, the limiting plane 91 and the transition arc surface 92 are respectively arranged on both sides of the second positioning protrusion 9, the aforementioned limiting plane 91 is close to the head 82, and the aforementioned transition arc surface 92 is close to the root 81. In addition, the limiting plane 91 is perpendicular to the insertion direction, and the second positioning groove 10 is provided with a stop plane for fitting with the limiting plane 91.

[0062] When assembling the elastic buckle 8 and the buckle mounting part, the operator presses the head 82 of the elastic buckle 8 toward the cylindrical shell 12, so that the head 82 and the root 81 of the elastic buckle 8 are both close to the cylindrical shell 12, and then squeezes the root 81 of the elastic buckle 8 into the buckle mounting part. When the root 81 of the elastic buckle 8 is gradually inserted inward into the buckle mounting part, the second positioning protrusion 9 continuously approaches the second positioning groove 10. Since the transition arc surface 92 is close to the root 81 and the limiting plane 91 is close to the head 82, during this operation, the transition arc surface 92 enters the buckle mounting part earlier than the limiting plane 91, which can guide the installation of the positioning protrusion and the buckle mounting part, and improve the smoothness of the insertion of the cylindrical shell 12 and the base 13. Once the elastic buckle 8 and its second positioning protrusion 9 are inserted into the buckle mounting portion, the second positioning protrusion 9 is embedded in the second positioning groove 10, and the limiting plane 91 of the second positioning protrusion 9 and the stop plane of the second positioning groove 10 fit each other, which can prevent the elastic buckle 8 from continuing to be inserted into the buckle mounting portion, thereby limiting the elastic buckle 8 and the buckle mounting portion.

[0063] For reference Fig.14 and Fig.15 In some embodiments, the base 13 includes a base platform 131, a first side stop 132 and more than two second side stops 133; wherein the base platform 131 is sleeve-shaped, the first side stop 132 and all the second side stops 133 are connected to the base platform 131, and the first side stop 132 and all the second side stops 133 are dispersed along the circumference of the base platform 131; the aforementioned second side stops 133 and the shell are closely spaced, and the buckle mounting portion is defined by the inner wall of any second side stop 133 and the outer wall of the shell; the aforementioned first side stop 132 can be used to install the fastener 100, in other words, the fastener 100 is arranged on the first side stop 132, when the shell and the base 13 are connected, the fastener 100 is inserted into the shell from the first side stop 132 of the base 13, and the base 13 and the shell are locked and fixed.

[0064] On the basis of the above embodiment, the second positioning groove 10 is specifically a rectangular through hole 21 arranged on the second side block 133, and accordingly, the root 81 of the second positioning protrusion 9 is rectangular and coincides with the rectangular through hole 21; the fastener 100 is specifically a spring screw, and an embedded nut is provided in the cylindrical shell 12. The head 82 of the spring screw is inserted into the cylindrical shell 12 and screwed on the embedded nut, thereby improving the connection strength of the spring screw to the cylindrical shell 12 and the base 13.

[0065] For reference Figures 13 to 15 In the above embodiment, the first side stop 132 is provided with a boss 1321 and a mounting hole 1322. The boss 1321 protrudes and extends outward along the radial direction of the base 13, and the mounting hole 1322 is provided in the boss 1321. When installing the spring screw, the neck of the spring screw is passed through the mounting hole 1322, and part of the spring of the spring screw is squeezed in the mounting hole 1322, which can prevent the screw from falling after the screw is screwed in.

[0066] In summary, the signal protection device provided by the present application optimizes the shape of the porous waterproof ring 2, improves the installation characteristics of the porous waterproof ring 2 and related components by adding a slit 22, and strengthens the installation strength of the porous waterproof ring 2 and the outer shell 1 by adding a first positioning groove 4 and a first positioning protrusion 5 of the outer shell 1, thereby limiting the movement of the porous waterproof ring 2 in the outer shell 1; the signal protection device provided by the present application also optimizes the sealing performance of multiple components of the outer shell 1, and sets gaskets of different shapes for the cylindrical shell 12 and the base 13 to ensure the waterproofness of different parts of the outer shell 1. The signal protection device provided in the present application also optimizes the installation performance of multiple components of the housing 1, and utilizes the elastic buckle 8 provided on the cylindrical shell 12 and the buckle mounting portion provided on the base 13 to make the assembly of the cylindrical shell 12 and the base 13 more convenient and firm, thereby greatly reducing the difficulty of installing the cylindrical shell 12 and the base 13. In addition, spring screws and related designs are used to further limit the position of the cylindrical shell 12 and the base 13. The spring screws can be firmly and reliably locked between the cylindrical shell 12 and the base 13 to ensure the relative fixed relationship between the cylindrical shell 12 and the base 13.

[0067] The signal protection device provided by the present application is introduced in detail above.
