[0036] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0037] The shielding layer is a wire with a metal braided outer shell specifically used to reduce the influence of external electromagnetic fields on power supply or communication lines. This kind of shielded wire also has the function of preventing the line from radiating electromagnetic energy outward. The shielding layer needs to be grounded, and the external interference signals can be introduced into the ground by this layer to avoid the interference signals from entering the inner conductor and reducing the loss of the transmitted signals at the same time.

[0038] In the related art, generally the following three methods are adopted to ground the cable shielding layer. Method 1: Peel off the protective layer of the shielded cable to expose the shielding layer, use a prefabricated pressing piece and connect it to the ground bar with screws to ensure the connection between the cable shielding layer and the equipment ground. Method 2: Peel off the protective layer of the shielded cable, expose the shielding layer and clamp it in the reed clip, and use the elasticity of the reed clip to ensure the connection between the cable shielding layer and the equipment ground. Method 3: Ground the cable shielding layer through a special mechanism and fix the cable with screws and pressing parts.

[0039] The above-mentioned method 1 for crimping shielding grounding is the most commonly used and simple. However, since the crimping piece is prefabricated, it can only adapt to specific wire diameters. Due to the use of two independent screws for fixing on-site, it is easy to fall off and the construction is inconvenient. The above-mentioned method 2 for clamping shielding grounding uses the self-elasticity of the reed to ensure the grounding reliability, and the on-site construction is convenient. However, the grounding of the shielding layer with different wire diameters depends on the elastic force of the reed to ensure reliability. Since the elastic force of the reed changes with the compression amount and has a certain range, the grounding and cable fixing reliability of the cable are reduced. The above-mentioned method 3 for mechanical shielding grounding crimping and fixing increases a special crimping mechanism to ensure the reliability of grounding and cable fixing. However, this method is mostly formed by machining or die-casting, with complex manufacturing processes and high costs; for on-site construction, since screw pressing and fixing are used, the screws need to be loosened and tightened at least twice, and the construction is complex.

[0040] To solve the above problems, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 shown, the cable shielding grounding structure of the embodiment of the present invention includes: a conductive connection part 1 and a conductive clamping part 2.

[0041] Specifically, the conductive connection part 1 can be made of a conductive material. For example, the conductive connection part 1 is made of tinned copper. Among them, the conductive connection part 1 can be a plate-like structure. In the case where the conductive connection part 1 is a rectangular sheet, both ends of the conductive connection part 1 are provided with rounded corners to improve the safety during installation and prevent harm to the installation personnel.

[0042] In addition, the conductive connection part 1 is provided with opposite connection surfaces 14 and installation surfaces 12. The connection surface 14 is adapted to be connected to the device 5 to be installed. In other words, the conductive connection part 1 is electrically connected to the device 5 to be installed through the connection surface 14.

[0043] In addition, the conductive clamping part 2 is arranged on the installation surface 12. The conductive clamping part 2 is provided with a clamping space 23. The clamping space 23 can cover the outer periphery of the cable. The clamping space 23 and the cable can be closely attached to each other, thereby increasing the contact stability and reliability between the clamping space 23 and the cable. Secondly, the size of the clamping space 23 is adjustable. For example, the clamping space 23 has a certain stretching ability to adapt to cables of different sizes and improve the application range.

[0044] Of course, a guiding port 24 communicating with the clamping space 23 is formed on the side of the conductive clamping part 2 away from the installation surface 12. The size of the guiding port 24 is adjustable. The cable enters the inside of the clamping space 23 through the guiding port 24. Exemplarily, the guiding port 24 has a certain stretching ability to adapt to cables of different sizes, so that cables of different sizes can enter the inside of the clamping space 23 through the guiding port 24.

[0045] Further, the conductive clamping portion 2 is further formed with a first wire passing port and a second wire passing port which are oppositely arranged. Both the first wire passing port and the second wire passing port are communicated with the clamping space 23. In other words, the first wire passing port and the second wire passing port are located in the length direction of the clamping space 23. That is to say, when the cable shielding layer 41 is located in the clamping space 23, the first end of the cable passes through the first wire passing port, and the second end of the cable passes through the second wire passing port.

[0046] In the embodiment of the present invention, the conductive connection portion 1 is electrically connected to the device to be installed 5 through the connection surface 14. The outer layer of the cable is stripped to expose the cable shielding layer 41. The cable shielding layer 41 can enter the inside of the clamping space 23 through the guiding port 24. The outer periphery of the cable shielding layer 41 is attached to the inner wall of the clamping space 23. The cable shielding layer 41 is electrically connected to the device to be installed 5 through the conductive clamping portion 2 and the conductive connection portion 1 in sequence. The installation is convenient, the cable can be reliably fixed in the conductive clamping portion 2, and thus reliable shielding grounding can be achieved.

[0047] In an optional embodiment, as Figure 3 and Figure 4 shown, the conductive clamping portion 2 includes a first conductive clamping portion 21 and a second conductive clamping portion 22 which are oppositely arranged. The first conductive clamping portion 21 and the second conductive clamping portion 22 are arranged on the mounting surface 12. The first conductive clamping portion 21 and the second conductive clamping portion 22 are symmetrically arranged. The first conductive clamping portion 21 and the second conductive clamping portion 22 enclose to form the clamping space 23.

[0048] Alternatively, in an optional embodiment, as Figure 3 and Figure 4 shown, the conductive clamping portion 2 includes a first conductive clamping portion 21 and a second conductive clamping portion 22 which are oppositely arranged. There is a gap between the first conductive clamping portion 21 and the second conductive clamping portion 22. At this time, a notch is formed on one side of the clamping space 23 close to the mounting surface 12.

[0049] It should be noted that the first conductive clamping portion 21 and the second conductive clamping portion 22 are arranged on the mounting surface 12. The first conductive clamping portion 21 and the second conductive clamping portion 22 are symmetrically arranged. The first conductive clamping portion 21 and the second conductive clamping portion 22 enclose to form the clamping space 23. There is a gap between the first conductive clamping portion 21 and the second conductive clamping portion 22, which can increase the clamping ability of the clamping space 23 to a certain extent. For example, when the diameter of the cable shielding layer 41 is large enough, the cable shielding layer 41 located in the clamping space 23 may directly abut against the mounting surface 12.

[0050] In practical applications, as Figure 3 and Figure 4As shown, each of the first conductive clamping portion 21 and the second conductive clamping portion 22 includes a support portion 211 extending away from the mounting surface 12 in a direction away from the mounting surface 12, a guiding portion 212 extending toward the mounting surface 12 from the support portion 211, and a clamping portion 213 extending toward the mounting surface 12 from the guiding portion 212.

[0051] The following takes the first conductive clamping portion 21 as an example for illustration. The first conductive clamping portion 21 includes a support portion 211, a guiding portion 212, and a clamping portion 213 that are connected in sequence. Specifically, the first conductive clamping portion 21 includes a support portion 211 extending away from the edge of the mounting surface 12 in a direction away from the mounting surface 12, a guiding portion 212 extending in a bent manner toward the mounting surface 12 from the support portion 211, and a clamping portion 213 extending toward the mounting surface 12 from the guiding portion 212. Among them, the support portion 211, the guiding portion 212, and the clamping portion 213 are all plate-like structures.

[0052] In an alternative embodiment, as Figure 3 and Figure 4 shown, the clamping portion 213 includes a first portion extending from the guiding portion 212 toward the support portion 211 and a second portion extending from the first portion in a direction away from the support portion 211.

[0053] Among them, the first portion and the second portion can be a semi-circle, that is to say, the clamping portion 213 is a semi-circular structure, so as to better fit the cable shielding layer 41. In addition, there is a certain distance between both the first portion and the second portion and the support portion 211, thereby providing additional space for the expansion of the clamping space 23.

[0054] In an alternative embodiment, as Figure 3 and Figure 4 shown, the angle between the support portion 211 and the guiding portion 212 is an acute angle.

[0055] It should be noted that the angle between the support portion 211 and the guiding portion 212 is 45°. At this time, the size of the guiding opening 24 gradually increases from the side close to the clamping space 23 to the side away from the clamping space 23, and the guiding opening 24 can adapt to cable shielding layers 41 of different sizes.

[0056] It can be understood that under the action of the extrusion force provided by the outside, the guiding portion 212 can move toward the support portion 211, thereby adjusting the size of the guiding opening 24.

[0057] In an alternative embodiment, as Figure 3 and Figure 4 shown, the support portion 211, the guiding portion 212, and the clamping portion 213 are integrally formed.

[0058] It should be noted that the supporting part 211, the guiding part 212 and the clamping part 213 can be made by sheet metal or injection molding.

[0059] In addition, the conductive connection part 1, the supporting part 211, the guiding part 212 and the clamping part 213 can be integrally formed.

[0060] In an alternative embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, at least one outer side surface of the supporting part 211 is provided with a clamping groove 2111 recessed toward the side where the clamping part 213 is located. The cable shielding grounding structure further includes a covering part 3. The covering part 3 is provided with a buckle 321 adapted to the clamping groove 2111. Through the cooperation connection of the buckle 321 and the clamping groove 2111, the covering part 3 is covered at the guiding port 24.

[0061] Exemplarily, both outer side surfaces of the two supporting parts 211 are provided with clamping grooves 2111 recessed toward the side where the clamping part 213 is located. Correspondingly, the covering part 3 includes a top wall 31 and two side walls located on opposite sides of the top wall 31. The two side walls are arranged oppositely, and both side walls are provided with buckles 321 adapted to the corresponding clamping grooves 2111. Under the cooperation connection of the buckles 321 and the clamping grooves 2111, the top wall 31 of the covering part 3 is covered at the guiding port 24.

[0062] In the embodiment of the present invention, the conductive connection part 1 is electrically connected to the device to be installed 5 through the connection surface 14. The outer layer of the cable is stripped so that the cable shielding layer 41 is exposed. The cable shielding layer 41 can enter the clamping space 23 through the guiding port 24. The outer periphery of the cable shielding layer 41 is attached to the inner wall of the clamping space 23. Thereafter, under the cooperation connection of the buckle 321 and the clamping groove 2111, the top wall 31 of the covering part 3 is covered at the guiding port 24. Thus, the grounding of the cable shielding layer 41 is completed. In other words, the cable shielding layer 41 is electrically connected to the device to be installed 5 through the conductive clamping part 2 and the conductive connection part 1 in sequence.

[0063] It should be particularly noted that when the top wall 31 of the covering part 3 is covered at the guiding port 24, the two side walls of the covering part 3 can squeeze the two supporting parts 211 located between the two side walls, so that the clamping part 213 can provide a stable and lasting clamping force on the cable shielding layer 41, so as to prevent the clamping space 23 from losing its telescopic ability after the clamping part 213 is used for a long time. In addition, by providing the covering part 3, the clamping part 213 can be adapted to cables with larger diameters.

[0064] In an alternative embodiment, as Figure 1 , Figure 2 , Figure 3 ,Figure 4 and Figure 6 As shown, a clamping groove 2111 recessed toward the side where the clamping portion 213 is located is provided on the outer side of one support portion 211, and an assembly hole 221 is provided on the other support portion 211; snap fasteners 321 and movable connection portions 331 are respectively provided on opposite sides of the covering portion 3, the movable connection portion 331 is provided in the assembly hole 221, and the covering portion 3 can rotate relative to the support portion 211 provided with the assembly hole 221.

[0065] It should be noted that a clamping groove 2111 recessed toward the side where the clamping portion 213 is located is provided on the outer side of one support portion 211, and an assembly hole 221 is provided on the outer side of the other support portion 211. Correspondingly, the covering portion 3 includes a top wall 31 and two side walls (a first side wall 32 and a second side wall 33) located on opposite sides of the top wall 31. The first side wall 32 and the second side wall 33 are oppositely arranged. The first side wall 32 is provided with a snap fastener 321 adapted to the corresponding clamping groove 2111, and the second side wall 33 is provided with a movable connection portion 331. The movable connection portion 331 is installed in the assembly hole 221. Under the cooperative connection of the snap fastener 321 and the clamping groove 2111, the top wall 31 of the covering portion 3 is covered at the guiding port 24.

[0066] In an embodiment of the present invention, the conductive connection portion 1 is electrically connected to the device to be installed 5 through the connection surface 14. The outer layer of the cable is stripped so that the cable shielding layer 41 is exposed. The covering portion 3 is rotated so that the guiding port 24 is exposed. The cable shielding layer 41 can enter the interior of the clamping space 23 through the guiding port 24, and the outer periphery of the cable shielding layer 41 is attached to the inner wall of the clamping space 23. Thereafter, the covering portion 3 is rotated, and under the cooperative connection of the snap fastener 321 and the clamping groove 2111, the top wall 31 of the covering portion 3 is covered at the guiding port 24. Thus, the grounding of the cable shielding layer 41 is completed.

[0067] In an optional embodiment, as Figure 4 and Figure 5 shown, the conductive connection portion 1 further includes an elastic conductive portion 15. The elastic conductive portion 15 has an opposite connection side and a free side. The connection surface 14 is provided with an avoidance groove 13, and the connection side is provided on the groove wall of the avoidance groove 13; wherein, the elastic conductive portion 15 has a first posture and a second posture. In the first posture, at least part of the free side is located outside the avoidance groove 13 and protrudes from the connection surface 14. In the second posture, the free side is located inside the avoidance groove 13.

[0068] Among them, a plurality of avoidance grooves 13 are sequentially arranged at intervals along the extending direction of the connection surface 14. Correspondingly, an elastic conductive portion 15 is provided in each avoidance groove 13.

[0069] It should be noted that when the conductive connection portion 1 is electrically connected to the device to be installed 5 through the connection surface 14, the elastic conductive portion 15 can always be in contact with the device to be installed 5, thereby increasing the grounding reliability.

[0070] In an alternative embodiment, as Figure 4 and Figure 5 shown, the elastic conductive part 15 is a metal sheet with elasticity.

[0071] It should be noted that the connecting side of the metal sheet is arranged on the groove wall of the avoidance groove 13. At this time, the connection point between the metal sheet and the avoidance groove 13 can be located at a position on the groove wall close to the notch of the avoidance groove 13, so that the metal sheet can have a certain activity space in the avoidance groove 13. The metal sheet has a first posture and a second posture. In the first posture, the metal sheet is in a bent state, and at least part of the metal sheet is located outside the avoidance groove 13 and protrudes from the connection surface 14. In the second posture, the metal sheet is located inside the avoidance groove 13, and the metal sheet is still in a bent state, so as to always keep in contact with the device to be installed 5, thereby increasing the grounding reliability.

[0072] In an alternative embodiment, a conductive adhesive layer is provided on the connection surface 14, and the cable shielding grounding structure is connected to the device to be installed 5 through the conductive adhesive layer.

[0073] In the embodiment of the present invention, the conductive connection part 1 is electrically connected to the device to be installed 5 through the conductive adhesive layer on the connection surface 14. After the conductive connection part 1 is electrically connected to the device to be installed 5, the outer layer of the cable is stripped to expose the cable shielding layer 41. The covering part 3 is rotated to expose the guiding port 24. At this time, the cable shielding layer 41 can enter the inside of the clamping space 23 through the guiding port 24, and the outer periphery of the cable shielding layer 41 fits with the inner wall of the clamping space 23. After that, the covering part 3 is rotated, and under the cooperation connection of the buckle 321 and the clamping groove 2111, the top wall 31 of the covering part 3 covers the guiding port 24, thereby completing the grounding of the cable shielding layer 41.

[0074] In an alternative embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the conductive connection part 1 is provided with mounting holes 11 penetrating through the connection surface 14 and the mounting surface 12. The cable shielding grounding structure further includes fasteners, and the fasteners are passed through the mounting holes 11 to connect the cable shielding grounding structure and the device to be installed 5.

[0075] Among them, two mounting holes 11 are provided on the conductive connection part 1, and the two mounting holes 11 are symmetrically arranged with respect to the conductive clamping part 2. At this time, the elastic conductive part 15 is located between the two mounting holes 11. The mounting holes 11 can be first threaded holes. Correspondingly, the fasteners can be screws. In other words, before installation, it is necessary to drill second threaded holes on the surface of the device to be installed 5 that are adapted to the screws, and the screws are sequentially passed through the first threaded holes and the second threaded holes to realize the connection between the conductive connection part 1 and the device to be installed 5.

[0076] In an embodiment of the present invention, the conductive connection part 1 is arranged on the surface of the device 5 to be installed, so that the first threaded hole and the second threaded hole are aligned. Then, screws are sequentially passed through the first threaded hole and the second threaded hole to realize the connection between the conductive connection part 1 and the device 5 to be installed. After the connection between the conductive connection part 1 and the device 5 to be installed is completed, the outer layer of the cable is stripped to expose the cable shielding layer 41. The covering part 3 is rotated to expose the guiding port 24. The cable shielding layer 41 can enter the inside of the clamping space 23 through the guiding port 24, and the outer periphery of the cable shielding layer 41 fits with the inner wall of the clamping space 23. After that, the covering part 3 is rotated, and under the cooperation connection of the buckle 321 and the clamping groove 2111, the top wall 31 of the covering part 3 covers the guiding port 24. Thus, the grounding of the cable shielding layer 41 is completed, and the grounding of the cable shielding layer 41 and the fixation of the cable can be quickly realized, improving the efficiency of on-site construction.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
