Description

Technical Field

[0001] This invention relates to the field of cable grounding box technology, and in particular to a highly reliable cable grounding box and a method for installing grounding components. Background Technology

[0002] During the laying of high-voltage cables, grounding systems are installed at appropriate locations to conduct the induced voltage generated during cable operation to the ground, eliminating the adverse effects of overvoltage and overcurrent on cable line operation. The grounding system mainly consists of grounding boxes, grounding cables, return cables, etc.

[0003] In related technologies, the grounding components inside the grounding box are fixed to the side plate of the box with metal bolts. When installing the grounding components, one person needs to hold the grounding components while another person tightens the bolts, which is cumbersome. In addition, the metal bolts also increase safety hazards. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an installation method for a highly reliable cable grounding box and grounding components.

[0005] According to a first aspect of the present invention, a high-reliability cable grounding box includes: a box body, the box body including a first side panel and a second side panel spaced apart from and opposite to the first side panel; the inner wall of the first side panel is provided with a first tenon structure, and the inner wall of the second side panel is provided with a second tenon structure opposite to the first tenon structure; the first tenon structure includes a first limiting member and a first tenon block, the first tenon block including a first support portion connected to the first limiting member and arranged along the width direction of the first side panel; the second tenon structure includes a second limiting member and a second tenon block, the second limiting member being opposite to the first limiting member, the second tenon block including a second support portion connected to the second limiting member and a stop block connected to the second support portion, the second support portion being opposite to the first support portion and arranged along the width direction of the second side panel with respect to the second limiting member. A stop block is connected to the end of the second support portion away from the second limiting member. The stop block has an insertion port that extends through both sides of the stop block along the width direction of the second side plate. A grounding assembly includes an insulating plate and a grounding mechanism disposed on the insulating plate. The first side end of the insulating plate has a first tenon joint, and the second side end of the insulating plate has a second tenon joint. The first side end of the insulating plate is positioned towards the first tenon joint structure, allowing the first support portion to pass through the first tenon joint. The second side end of the insulating plate is positioned towards the second tenon joint structure, allowing the second support portion to pass through the second tenon joint. The second tenon joint structure further includes a pressure plate disposed between the stop block and the insulating plate, and a tenon post passing through the insertion port, the pressure plate, and the second tenon joint. The first side plate, the second side plate, the first tenon joint structure, and the second tenon joint structure are all non-conductive components.

[0006] According to a second aspect of the present invention, a method for installing a grounding assembly, applied to a high-reliability cable grounding box as described above, includes:

[0007] The first side end of the insulating plate of the grounding assembly is inserted obliquely into the first tenon structure until the first tenon joint is inserted by the first support portion. When the first side end of the insulating plate is inserted obliquely into the first tenon structure, the distance between the second side end of the insulating plate and the second limiting member along the width direction of the second side plate is greater than the distance between the first side end of the insulating plate and the first limiting member along the width direction of the first side plate.

[0008] During the process of the first tenon being inserted into the first support, the second side end of the insulating plate is deflected toward the second limiting member until the second tenon is inserted into the second support.

[0009] The pressure plate is inserted between the stop block and the insulating plate;

[0010] The tenon joint is inserted through the insertion port of the stop block, the pressure plate, and the second tenon joint.

[0011] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0041] like Figure 1 As shown, an embodiment of the present invention relates to a cable grounding box, which includes a box body 100.

[0042] Combination Figure 1 and Figure 2 The housing 100 includes a side panel assembly 110, which includes a plurality of connected side panels 1101. Specifically, in this embodiment, the side panel assembly 110 includes a rear side panel 111 and two side side panels 112. The rear ends of the two side side panels 112 are respectively connected to the two opposite ends of the rear side panel 111 in the horizontal direction, and the two side side panels 112 are spaced apart and arranged opposite to each other.

[0043] Combination Figure 2 , Figure 6 and Figure 7 At least one side plate 1101 is provided with a rainproof structure 1102. The rainproof structure 1102 includes multiple rainproof parts arranged along the direction of gravity. The rainproof parts include a deflector plate 11021 and a protective plate 11022. The top of the deflector plate 11021 is located close to the inner side of the side plate 1101, and the deflector plate 11021 is gradually inclined towards the outer side of the side plate 1101 from top to bottom. The top of the protective plate 11022 is connected to the bottom of the deflector plate 11021.

[0044] It is understood that a rainproof structure 1102 can be provided on one of the side plates 1101, or it can be provided on two or more side plates 1101. Specifically, in this embodiment, the rainproof structure 1102 is provided on the side plate 112. The rainproof structure 1102 includes multiple rainproof parts arranged from top to bottom, and each rainproof part has the same structure; for each rainproof part: its guide plate 11021 is inclined, and the top of the guide plate 11021 is close to the inner side of the side plate 1101, and the bottom of the guide plate 11021 is close to the outer side of the side plate 1101. In other words, the guide plate 11021 is gradually inclined towards the outer side of the side plate 1101 from top to bottom; for each rainproof part: the top of its protective plate 11022 is connected to the bottom of the guide plate 11021, and its protective plate 11022 extends vertically downward from its top. In addition, in each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section is disposed opposite to the outer wall of the guide plate 11021 of the lower rainproof section.

[0045] Furthermore, for each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section is offset from the top of the guide plate 11021 of the lower rainproof section, and a removable baffle 11023 is provided between the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section.

[0046] Specifically, for each pair of adjacent rainproof sections: the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section are horizontally offset, and the baffle 11023 blocks the gap formed by the offset between the bottom of the protective plate 11022 of the upper rainproof section and the top of the guide plate 11021 of the lower rainproof section.

[0047] It should be noted that the baffle 11023 is configured to be broken so that a vent is formed between the bottom of the protective plate 11022 of the upper rainproof part and the top of the guide plate 11021 of the lower rainproof part.

[0048] Specifically, the baffle 11023 has a thin-walled structure, and its thickness can be set to be greater than or equal to 0.1 mm and less than or equal to 2 mm. In this way, the baffle 11023 can be knocked off or poked off by the staff with the help of tools, thereby forming a ventilation opening for connecting the interior of the enclosure 100 with the outside.

[0049] When the cable grounding box of the present invention is used: if the internal electrical components do not require heat dissipation and ventilation, or if the area where it is installed is in a humid environment for a long time, then it is not necessary to remove the baffle 11023. The entire box 100 has a high sealing effect, which can reduce the risk of damage to the internal electrical components due to water immersion. If the internal electrical components require heat dissipation and ventilation, the baffle 11023 can be removed to form a ventilation opening for ventilation. Furthermore, when the baffle 11023 is removed, in rainy weather, after the rainwater falls on the side plate 1101, most of it will flow down the outer surface of the protective plate 11022, and a small amount will flow to the lower surface of the bottom of the protective plate 11022 and drip onto the guide plate 11021, and flow down along the guide plate 11021. It is difficult for the rainwater to enter the interior of the box 100, thus also achieving the effect of preventing rain.

[0050] like Figure 5 As shown, in some embodiments, the inner walls of the two opposite ends of the rear side plate 111 along the horizontal direction are provided with sealing strips 1112, and the two side plates 112 respectively seal against the sealing strips 1112 at the two opposite ends of the rear side plate 111 along the horizontal direction.

[0051] It is understandable that after the side plate 112 and the rear plate 111 are properly fitted together, the side plate 112 abuts against the sealing strip 1112, thereby achieving a seal between the side plate 112 and the rear plate 111.

[0052] Furthermore, the inner walls of the two opposite ends of the rear side plate 111 along the horizontal direction are provided with first mounting grooves 1111, and each first mounting groove 1111 is provided with a sealing strip 1112. The first mounting groove 1111 is used to position the sealing strip 1112, improve the positioning accuracy of the sealing strip 1112, and also prevent the sealing strip 1112 from shifting when squeezed by the side plate 112.

[0053] Combination Figure 2 and Figure 5 Furthermore, the enclosure 100 also includes a door frame 120 and a door 130. The door frame 120 is connected to the front end of the two side panels 112. The inner wall of the door 130 is provided with a sealing ring 132. When the door 130 is in the closed state, the door 130 covers the front side of the door frame 120 and the sealing ring 132 abuts against the door frame 120.

[0054] It is understandable that when the door 130 is closed, the door 130 covers the front side of the door frame 120 and the sealing ring 132 abuts against the door frame 120, thus achieving a seal between the door 130 and the door frame 120.

[0055] Specifically, a second mounting groove 131 is provided around the inner side wall of the door 130, and a sealing ring 132 is disposed in the second mounting groove 131. The second mounting groove 131 is used to position the sealing ring 132, improve the positioning accuracy of the sealing ring 132, and also prevent the sealing ring 132 from shifting when squeezed by the door frame 120.

[0056] Furthermore, the outer wall of the door frame 120 is provided with ribs 121, which are used to abut against the sealing ring 132 to form a seal.

[0057] like Figure 2 As shown, it should be noted that the cabinet door 130 is rotatably connected to one of the side panels 112 by means of hinges. The number of hinges can be multiple, thereby improving the reliability of the connection between the cabinet door 130 and the side panel 112. Furthermore, using multiple hinges to connect the cabinet door 130 can also improve the sealing effect of the cabinet door 130 when it is closed.

[0058] Furthermore, a door lock is also provided on the door 130, which can be used to lock the door.

[0059] like Figure 2 As shown, in some embodiments, the housing 100 further includes a bottom plate assembly 160, which is connected to the bottom of a plurality of side plates 1101.

[0060] like Figures 9 to 11As shown, the base plate assembly 160 is provided with a wire through hole 1601 that runs through the upper and lower sides of the base plate assembly 160, and a wire through structure 163 is provided in the wire through hole 1601.

[0061] Further details can be found in [link / reference]. Figure 11 The cable passage structure 163 includes multiple cable passage coils 1631. The inner diameters of the different cable passage coils 1631 are different. The cable passage coils 1631 with larger inner diameters are arranged around the cable passage coils 1631 with smaller inner diameters. A connecting part 1632 is provided between each two adjacent cable passage coils 1631, and between the cable passage coil 1631 with the largest inner diameter and the wall of the cable passage hole 1601.

[0062] It is understood that the multiple cable pass coils 1631 are concentric, and all of them are concentrically arranged with the through hole 1601. The cable pass coil 1631 can be a complete loop structure, a non-closed loop structure, or other irregular shapes. Each pair of adjacent cable pass coils 1631 is connected by a connecting part 1632, and the cable pass coil 1631 with the largest inner diameter is connected to the wall of the through hole 1601 by the connecting part 1632.

[0063] In this embodiment, the connecting portion 1632 located between two adjacent cable loopers 1631 and the two cable loopers 1631 connected thereto are detachably connected. In other words, the connecting portion 1632 and the cable loopers 1631 connected thereto can be separated. Separation of the connecting portion 1632 and the cable loopers 1631 can be achieved by, but is not limited to, breaking the connection between the connecting portion 1632 and the cable loopers 1631. Of course, in other embodiments, one of the connecting portion 1632 located between two adjacent cable loopers 1631 and the two cable loopers 1631 connected thereto is detachably connected.

[0064] In addition, the connection portion 1632 between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601, and the cable coil 1631 and / or the wall of the through hole 1601 connected thereto are detachably connected.

[0065] In the base plate assembly 160 of the present invention, each cable pass coil 1631 is a removable structure. Depending on the diameter of the cable 300, the cable pass coil 1631 with a smaller inner diameter can be knocked off, so that the cable 300 can pass through the cable pass coil 1631 that matches the diameter of the cable 300. In this way, the requirement for the cable 300 to pass through is met, and at the same time, it is also ensured that there is no large gap between the inner wall of the cable pass coil 1631 and the cable 300. This can reduce the amount of sealant used, save costs, improve the adhesion of the sealant, reduce the risk of sealant falling off, and improve sealing performance.

[0066] Furthermore, a plurality of connecting portions 1632 are provided between each pair of adjacent cable pass coils 1631, arranged around the axis of the through hole 1601. This improves the reliability of the connection between each pair of adjacent cable pass coils 1631.

[0067] Similarly, a plurality of connecting portions 1632 are provided between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601, arranged around the axis of the through hole 1601. In this way, the reliability of the connection between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601 can be improved.

[0068] It should be noted that the thickness of the connecting portion 1632 is less than the thickness of the cable loop 1631, and the thickness directions of both the connecting portion 1632 and the cable loop 1631 are parallel to the axial direction of the through hole 1601. This allows the connecting portion 1632 to be knocked off relatively easily. The thickness of the connecting portion 1632 can be set between 1mm and 3mm.

[0069] The cable coil 1631, the connecting part 1632, and the wall of the through hole 1601 can be integrally formed.

[0070] It should be noted that, in order to accommodate more types of cables 300, the through hole 1601 does not have to be a regular circle; it can be other irregular structures.

[0071] like Figure 9 As shown, in some embodiments, the base plate assembly 160 is further provided with a closed groove 165, and the portion surrounded by the groove 165 is defined as a knockable cover 166. It is understood that the knockable cover 166 can be knocked down to form a cable pass-through opening on the base plate assembly 160, allowing other cables 300 to pass through. Of course, when no additional cable 300 is needed, the knockable cover 166 will not be knocked down, ensuring the sealing effect of the base plate assembly 160.

[0072] Combination Figure 9 and Figure 10In some embodiments, the base plate assembly 160 includes an outer frame 161 and a flap 162. The outer frame 161 is provided with an opening. The flap 162 is rotatably connected to the outer frame 161 and can be lifted to cover the opening. A wire through hole 1601 is formed in the flap 162.

[0073] Understandably, the flap 162 is rotatably connected to the outer frame 161, and the flap 162 is configured to be able to flip and adjust the angle. In this way, even if the cable 300 passes through the base plate assembly 160 into the interior of the housing 100, the cable 300 has greater freedom and can be easily inserted into different positions.

[0074] Specifically, the flap 162 includes a first flap 1621 and a second flap 1622. One side of the first flap 1621 is rotatably connected to one side of the opening of the outer frame 161, and one side of the second flap 1622 is rotatably connected to the other side of the opening of the outer frame 161. The first flap 1621 and the second flap 1622 are arranged side by side. The wire through hole 1601 includes a first half hole 1601a formed on the side of the first flap 1621 near the second flap 1622, and a second half hole 1601b formed on the side of the second flap 1622 near the first flap 1621. A portion of the structure of each cable coil 1631 is disposed in the first half hole 1601a, and the other portion of the structure of each cable coil 1631 is disposed in the second half hole 1601b.

[0075] It should be noted that the flap 162 is configured to flip upward relative to the outer frame 161 and is restricted from flipping downward relative to the outer frame 161. In this way, when the cable 300 passes through the base plate assembly 160 into the housing 100, there is no need to worry about the flap 162 flipping downward and affecting the assembly.

[0076] Specifically, the first flap 1621 is rotatably connected to the outer frame 161 via the first hinge 1641. The first hinge 1641 is located on the upper side of the outer frame 161. One hinge of the first hinge 1641 is connected to the upper side of the outer frame 161, and the other hinge is connected to the upper side of the first flap 1621. When the first flap 1621 is in the closed state, the side wall of the first flap 1621 near its rotation axis is in contact with the side wall of the opening of the outer frame 161, and the side wall of the opening restricts the first flap 1621 from flipping downward.

[0077] Similarly, the second flap 1622 is rotatably connected to the outer frame 161 via the second hinge 1642. The second hinge 1642 is located on the upper side of the outer frame 161. One hinge of the second hinge 1642 is connected to the upper side of the outer frame 161, and the other hinge is connected to the upper side of the second flap 1622. When the second flap 1622 is in the closed state, the side wall of the second flap 1622 near its rotation axis is in contact with the side wall of the opening of the outer frame 161, and the side wall of the opening restricts the second flap 1622 from flipping downward.

[0078] like Figure 8 , Figure 9 As shown, in some embodiments, the upper surface of the base plate assembly 160 is provided with a raised protrusion 167 located on the rotation path of the door 130, and the raised protrusion 167 gradually increases in height along the closing direction of the door 130. Thus, during the closing process, the door 130 is gradually pulled up, making the door 130 more stable and reducing the risk of the door 130 shaking. It is understood that a more stable door 130 allows for better resistance between the sealing ring 132 on the inner side of the door 130 and the door frame 120, thereby improving the sealing performance.

[0079] Specifically, the base plate assembly 160 is provided with two raised protrusions 167, which are arranged on the upper surface of the base plate assembly 160, one on the left and one on the right. This makes the left and right sides of the door 130 raised to a more consistent height.

[0080] like Figure 2 , Figure 3 As shown, the enclosure 100 also includes a cover 140, which covers the top of the multiple side panels 1101. The projection of the cover 140 on the horizontal plane overlaps the projections of the multiple side panels 1101 on the horizontal plane. In this way, the cover 140 can serve as a rain cover, reducing the risk of rainwater entering the interior of the enclosure 100.

[0081] like Figures 2 to 4 As shown, in some embodiments, the housing 100 further includes a storage shell 150 disposed on the side panel assembly 110, with the periphery of the storage shell 150 disposed on each side panel 1101. The storage shell 150 can be used to house some electrical components, such as intelligent processing devices.

[0082] Furthermore, the edges of the lid 140 surround the perimeter of the storage shell 150, and the perimeter of the storage shell 150 surrounds the perimeter of the side panel assembly 110. When it rains, most of the rainwater can flow away along the lid 140, reducing the risk of entering the interior of the box 100.

[0083] like Figure 12As shown, the storage shell 150 includes a bottom shell 151 and a top cover 152. The bottom shell 151 has a shell opening, and the top cover 152 covers the shell opening and the edge of the top cover 152 is arranged around the edge of the shell opening.

[0084] Specifically, the bottom shell 151 is a hollow structure with a shell opening at the top, and the top cover 152 is used to cover the shell opening to seal it. The edge of the top cover 152 is set around the edge of the shell opening, which can further improve the sealing effect.

[0085] Furthermore, the upper surface of the cover 152 has a flow guiding structure 1521 and a drainage groove 1522 located on the lower side of the flow guiding structure 1521. The bottom wall of the drainage groove 1522 is provided with a drainage hole 1523. The drainage hole 1523 is separated from the internal space of the bottom shell 151, and the bottom of the drainage hole 1523 is a non-blocking structure.

[0086] Understandably, if condensation occurs inside the cabinet 100 due to temperature differences between day and night, when the condensation drips onto the top cover 152, it will enter the drain groove 1522 along the guide structure 1521 and then be discharged through the drain hole 1523. In this way, the risk of condensation entering the storage shell 150 and damaging the electrical components inside the storage shell 150 can be reduced.

[0087] like Figure 3 As shown, the storage shell 150 is disposed within the space enclosed by the side panel assembly 110 and located at the upper end of the side panel assembly 110, with the top cover 152 facing the box cover 140.

[0088] Understandably, the upper cover 152 acts as a separator, dividing the space between the bottom shell 151 and the lid 140. This separates the internal space of the bottom shell 151 from the internal space of the upper cover 152, effectively dividing a larger space into two smaller ones. Smaller spaces mean a smaller total air volume, consequently reducing the amount of water vapor they can hold. Furthermore, condensation is often related to temperature differences. When warm, humid air encounters a cooler surface, water vapor easily condenses into water droplets. Reducing the space allows for a more uniform temperature distribution and reduces temperature gradients. Smaller spaces facilitate overall temperature balance, with weaker convection between cold and warm air, reducing the likelihood of localized excessively low or high temperatures and thus lowering the risk of water vapor condensation due to temperature differences.

[0089] It should be noted that the problem of condensation can also be further improved by adding multiple separators in the space between the bottom shell 151 and the cover 140.

[0090] Furthermore, the walls of the space formed by the lid 140 and the storage shell 150 are provided with insulating cotton. In this way, the rate of temperature change inside the box 100 can be slowed down, while also absorbing a small amount of condensation and reducing condensation dripping.

[0091] Combination Figure 13 and Figure 14 In some embodiments, the middle of the cover 152 is arched to form a flow guide structure 1521, and a drainage groove 1522 is provided on the side of the cover 152.

[0092] Specifically, the flow guiding structure 1521 includes an inclined first flow guiding surface 1521a and an inclined second flow guiding surface 1521b. The first flow guiding surface 1521a and the second flow guiding surface 1521b are arranged side by side, and the higher sides of the first flow guiding surface 1521a and the second flow guiding surface 1521b are close to the middle of the upper surface of the upper cover 152. The lower sides of the first flow guiding surface 1521a and the second flow guiding surface 1521b are respectively located on both sides of the upper cover 152. The drainage channel 1522 includes a first drainage channel 1522a disposed on the lower side of the first flow guiding surface 1521a and a second drainage channel 1522b disposed on the lower side of the second flow guiding surface 1521b.

[0093] It is understood that the bottom walls of both the first drainage trough 1522a and the second drainage trough 1522b are provided with drainage holes 1523. When condensation drips onto the upper surface of the cover 152, the condensation can enter the corresponding drainage trough 1522 along the first guide surface 1521a and / or the second guide surface 1521b, and be discharged through the drainage holes 1523 on the drainage trough 1522.

[0094] Furthermore, the bottom wall of the drainage channel 1522 can be inclined, and the drainage hole 1523 is located at the lower part of the bottom wall of the drainage channel 1522.

[0095] Furthermore, the bottom shell 151 is provided with a through hole opposite to the drain hole 1523, so as to prevent the bottom shell 151 from blocking the bottom end of the drain hole 1523.

[0096] like Figure 12 As shown, in some embodiments, the bottom shell 151 is provided with slots 1511 on both sides opposite to the shell opening, and the opposite sides of the top cover 152 are respectively engaged in the slots 1511 on the opposite sides of the shell opening. In this way, the top cover 152 can be fixed.

[0097] Combination Figure 2 , Figure 7 and Figure 14 As shown, the side wall of the bottom shell 151 is provided with a removable closed window 1512 that is disposed opposite to the rainproof structure 1102.

[0098] Understandably, if ventilation and heat dissipation of the electrical components inside the storage housing 150 are not required, the closed window 1512 may not be removed; if ventilation and heat dissipation of the electrical components inside the storage housing 150 are required, the closed window 1512 may be removed, as well as the baffle 11023, to facilitate ventilation.

[0099] It should be noted that multiple parallel transverse recessed grooves can be provided on the side wall of the bottom shell 151, which makes it easier to break this part of the side wall of the bottom shell 151.

[0100] like Figure 15 As shown, the cable grounding box also includes a grounding component 200 disposed within the box body 100.

[0101] Of the two side panels 112, one is a first side panel 1121 and the other is a second side panel 1122. The first side panel 1121 and the second side panel 1122 are spaced apart and arranged opposite to each other.

[0102] Combination Figure 15 , Figure 17 and Figure 18 The inner wall of the first side plate 1121 is provided with a first tenon structure 11211, and the inner wall of the second side plate 1122 is provided with a second tenon structure 11221 that is opposite to the first tenon structure 11211. It can be understood that the two ends of the grounding component 200 are respectively connected to the first tenon structure 11211 and the second tenon structure 11221 to achieve fixation.

[0103] like Figure 17 As shown, the first tenon structure 11211 includes a first limiting member 112111 and a first tenon block 112112. The first tenon block 112112 includes a first support portion 1121121 connected to the first limiting member 112111 and arranged along the width direction of the first side plate 1121.

[0104] Specifically, the first limiting member 112111 is connected to the inner wall of the first side plate 1121 and extends vertically, the first tenon block 112112 is connected to one side of the first limiting member 112111 along the width direction of the first side plate 1121, and the first tenon block 112112 has a first support portion 1121121. The first support portion 1121121 and the first limiting member 112111 are arranged along the width direction of the first side plate 1121, wherein the first limiting member 112111 protrudes more from the inner wall of the first side plate 1121 than the first support portion 1121121.

[0105] like Figure 18As shown, the second tenon joint structure 11221 includes a second limiting member 112211 and a second tenon joint block 112212. The second limiting member 112211 is disposed opposite to the first limiting member 112111. The second tenon joint block 112212 includes a second supporting portion 1122121 connected to the second limiting member 112211 and a blocking block 1122122 connected to the second supporting portion 1122121. The second supporting portion 1122121 is disposed opposite to the first supporting portion 1121121 and is arranged with the second limiting member 112211 along the width direction of the second side plate 1122. The blocking block 1122122 is connected to one end of the second supporting portion 1122121 away from the second limiting member 112211. The blocking block 1122122 is provided with an insertion opening 11221221, and the insertion opening 11221221 penetrates through both sides of the blocking block 1122122 along the width direction of the second side plate 1122.

[0106] Specifically, the second limiting member 112211 is connected to the inner side wall of the second side plate 1122 and extends vertically, and the second limiting member 112211 is arranged side by side and spaced apart and opposite to the first limiting member 112111; the second tenon joint block 112212 is connected to one side of the second limiting member 112211 along the width direction of the second side plate 1122; the second supporting portion 1122121 is arranged with the second limiting member 112211 along the width direction of the second side plate 1122 and is disposed opposite to the first supporting portion 1121121; wherein, the second limiting member 112211 protrudes more from the inner side wall of the second side plate 1122 than the second supporting portion 1122121; the blocking block 1122122 is connected to one end of the second supporting portion 1122121 away from the second limiting member 112211, and the blocking block 1122122 protrudes more from the inner side wall of the second side plate 1122 than the second supporting portion 1122121. The blocking block 1122122 is spaced apart from the second limiting member 112211 along the width direction of the second side plate 1122, and a gap is formed between the blocking block 1122122 and the second limiting member 112211. Among them, the insertion opening 11221221 on the blocking block 1122122 penetrates through both sides of the blocking block 1122122 along the width direction of the second side plate 1122 and communicates with the gap.

[0107] As Figure 16 shown, the grounding assembly 200 includes an insulating plate 210 and a grounding mechanism 220 disposed on the insulating plate 210. A first tenon joint 211 is provided at the first side end of the insulating plate 210, and a second tenon joint 212 is provided at the second side end of the insulating plate 210. Among them, combining Figure 19 and Figure 20The first side end of the insulating plate 210 is disposed toward the first tenon structure 11211 and the first support part 1121121 passes through the first tenon interface 211. The second side end of the insulating plate 210 is disposed toward the second tenon structure 11221 and the second support part 1122121 passes through the second tenon interface 212.

[0108] Specifically, the insulating plate 210 is used to support the grounding mechanism 220, which is used to connect the cable 300. The two ends of the insulating plate 210 are respectively connected to the first tenon joint 11211 and the second tenon joint 11221. The insulating plate 210 includes opposing two ends, one of which is the first end and the other is the second end. A first tenon joint 211 is formed on the first end of the insulating plate 210, and a second tenon joint 212 is formed on the second end of the insulating plate 210. The first end of the insulating plate 210 is positioned towards the first tenon joint 11211, and a first support portion 1121121 passes through the first tenon joint 211. Thus, under the action of the first support portion 1121121, the first end of the insulating plate 210 can be limited vertically. Additionally, under the action of the first limiting member 112111, the first end of the insulating plate 210 can be limited on one side along the width direction of the first side plate 1121. The second side end of the insulating plate 210 is positioned toward the second tenon structure 11221, and the second support portion 1122121 passes through the second tenon interface 212. Thus, under the action of the second support portion 1122121, the second side end of the insulating plate 210 can be limited in the vertical direction. In addition, under the action of the second limiting member 112211, the second side end of the insulating plate 210 can be limited on one side along the width direction of the second side plate 1122.

[0109] like Figure 20 As shown, the second tenon structure 11221 further includes a pressure plate 112213 and a tenon post 112214. The pressure plate 112213 is disposed between the stop block 1122122 and the insulating plate 210. The tenon post 112214 passes through the insertion port 11221221 of the stop block 1122122, the pressure plate 112213 and the second tenon interface 212.

[0110] Understandably, the pressure plate 112213 is positioned between the stop block 1122122 and the insulating plate 210. The pressure plate 112213 can press the second side end of the insulating plate 210 together, thus fixing the entire insulating plate 210 to the housing 100. The tenon joint 112214 passes through the insertion port 11221221 of the stop block 1122122, the pressure plate 112213, and the second tenon joint 212. At this time, the tenon joint 112214 restricts the pressure plate 112213 from disengaging from the direction opposite to the second support part 1122121, thus positioning the pressure plate 112213.

[0111] When assembling the cable grounding box of the present invention, firstly, the first side end of the insulating plate 210 of the grounding assembly 200 is inserted obliquely into the first tenon structure 11211 until the first tenon joint 211 is inserted into the first support part 1121121. It should be noted that when the first side end of the insulating plate 210 is inserted obliquely into the first tenon structure 11211, the oblique state of the insulating plate 210 is such that the distance between the second side end of the insulating plate 210 and the second limiting member 112211 along the width direction of the second side plate 1122 is greater than the distance between the first side end of the insulating plate 210 and the first limiting member 112111 along the width direction of the first side plate 1121. During the insertion of the first tenon joint 211 into the first support part 1121121, the second side end of the insulating plate 210 can be deflected toward the second limiting member 112211 until the second tenon joint 212 is inserted into the second support part 1122121. Then, the pressure plate 112213 is inserted between the stop block 1122122 and the insulating plate 210. Finally, the tenon joint 112214 is inserted through the insertion port 11221221 of the stop block 1122122, the pressure plate 112213, and the second tenon joint 212, thereby restricting the pressure plate 112213 from coming out from the direction away from the second support part 1122121, thus achieving the positioning of the pressure plate 112213. The cable grounding box of the present invention can be assembled without bolts during the assembly of the grounding component 200 into the box body 100. The entire operation can be completed independently by a single worker, making the operation simple.

[0112] like Figure 20 As shown, it should be noted that a plane parallel to the inner surface of the first side plate 1121 is defined as the reference plane, the projection of the second tenon joint 212 on the reference plane is the first projection, the projection of the second support part 1122121 on the reference plane is the second projection, and the projection of the stop block 1122122 on the reference plane is the third projection; wherein, the top of the second projection and the third projection are not higher than the top of the first projection, and the bottom of the second projection and the third projection are not lower than the bottom of the first projection.

[0113] Thus, during the assembly of the grounding assembly 200, when the first tenon joint 211 is inserted into the first support part 1121121, and the second side end of the insulating plate 210 is deflected toward the second limiting member 112211 until the second tenon joint 212 is inserted into the second support part 1122121, since the dimension of the second tenon joint 212 in the height direction is greater than the dimension of the second support part 1122121 and the stop block 1122122 in the height direction of the second support part 1122121, the second support part 1122121 and the stop block 1122122 will not interfere with the step of "the second side end of the insulating plate 210 is deflected toward the second limiting member 112211 until the second tenon joint 212 is inserted into the second support part 1122121".

[0114] Combination Figure 17 and Figure 19 Furthermore, the first tenon block 112112 also includes an anti-detachment part 1121122 connected to the side of the first support part 1121121 away from the first limiting member 112111, and the anti-detachment part 1121122 is limited and engaged with the first side end of the insulating plate 210.

[0115] It is understood that the top of the anti-detachment part 1121122 is higher than the top of the first support part 1121121, and / or the bottom of the anti-detachment part 1121122 is lower than the bottom of the first support part 1121121; when the first tenon joint 211 is inserted by the first support part 1121121, the first limiting member 112111 and the anti-detachment part 1121122 can move the first side end of the insulating plate 210 along the width direction of the first side plate 1121. In this way, the first tenon joint structure 11211 can be used to limit the front-back and up-down directions of the first side end of the insulating plate 210.

[0116] Furthermore, the distance between the side of the anti-detachment portion 1121122 near the first limiting member 112111 and the side of the first limiting member 112111 near the anti-detachment portion 1121122 is equal to the thickness of the insulating plate 210. This reduces the risk of loosening between the first end of the insulating plate 210 and the first limiting member 112111 and the anti-detachment portion 1121122. Of course, to facilitate the insertion of the first end of the insulating plate 210 between the first limiting member 112111 and the anti-detachment portion 1121122, the distance between the side of the anti-detachment portion 1121122 near the first limiting member 112111 and the side of the first limiting member 112111 near the anti-detachment portion 1121122 can be slightly greater than the thickness of the insulating plate 210.

[0117] like Figure 20 , Figure 21As shown, in some embodiments, the pressure plate 112213 is provided with an insertion hole 1122131 located between the insertion port 11221221 and the second tenon interface 212. The tenon post 112214 is sequentially inserted through the insertion port 11221221, the insertion hole 1122131, and the second tenon interface 212, and the tenon post 112214 is interference-fitted with the insertion hole 1122131. The outer diameter of the tenon post 112214 gradually increases along the direction from the second limiting member 112211 to the stop block 1122122.

[0118] Thus, when the tenon joint 112214 is sequentially inserted into the insertion port 11221221, the insertion hole 1122131, and the second tenon interface 212, the deeper the tenon joint 112214 is inserted, the more tightly the tenon joint 112214 is pressed against the hole wall of the insertion hole 1122131, thereby achieving the connection between the tenon joint 112214 and the pressure plate 112213. At the same time, the side walls of the second tenon interface 212 and the second support part 1122121 can prevent the tenon joint 112214 from coming out, thereby preventing the pressure plate 112213 from coming out.

[0119] It should be noted that the upper and lower side walls of the insertion port 11221221 can also limit the upper and lower positions of the tenon post 112214, thereby limiting the upper and lower positions of the pressure plate 112213.

[0120] like Figure 20 , Figure 21 As shown, in some embodiments, the pressure plate 112213 has a third tenon joint 1122132 on the side near the second support portion 1122121, and at least a portion of the second support portion 1122121 passes through the third tenon joint 1122132. In this way, the second support portion 1122121 can serve to support the pressure plate 112213.

[0121] Furthermore, the upper and lower sidewalls of the third tenon joint 1122132 abut against the upper and lower sidewalls of the second support portion 1122121, respectively. In this way, the second support portion 1122121 can also restrict the vertical movement of the pressure plate 112213, and this method also allows the pressure plate 112213 to be clamped within the second support portion 1122121, thereby achieving the connection between the pressure plate 112213 and the second support portion 1122121.

[0122] The distance between the upper and lower sidewalls of the third tenon joint 1122132 gradually increases along the direction from the first side plate 1121 to the second side plate 1122.

[0123] It is understandable that when assembling the pressure plate 112213, the assembly is carried out from the first side plate 1121 to the second side plate 1122. When the pressure plate 112213 is assembled, the upper and lower side walls of the third tenon joint 1122132 will be squeezed tighter and tighter with the upper and lower side walls of the second support part 1122121.

[0124] It should be noted that the side panel assembly 110, the first tenon structure 11211, and the second tenon structure 11221 described above are all non-conductive components. Specifically, the first side panel 1121, the second side panel 1122, the first limiting member 112111, the first tenon block 112112, the second limiting member 112211, the second tenon block 112212, the pressure plate 112213, and the tenon post 112214 are all non-conductive components. These components can be made entirely of insulating material, or they can have an insulating layer coated or wrapped on their surface to prevent them from conducting electricity.

[0125] Thus, by using the first tenon joint 11211 and the second tenon joint 11221 to connect the insulating plate 210 to the side plate 1101, compared to the traditional method of using metal bolts to connect the insulating plate 210 to the side plate 1101, the problem of corona discharge caused by the ionization of the surrounding air due to the sharp corners and edges of the metal bolts under the action of a strong electric field is avoided. Corona discharge can trigger a series of chemical reactions, producing highly corrosive substances such as ozone, nitric oxide, and nitrogen dioxide, which can easily cause conductor corrosion of the high-voltage grounding component 200, reduce the conductivity of the conductor, and even cause conductor overheating failure. In addition, corona discharge generates high-frequency pulse current, which contains various high-order harmonics that can cause radio waves to the grounding box's own intelligent processing device and even other surrounding equipment. Interference; Corona discharge consumes energy, increases power loss in transmission lines, causes unnecessary energy loss in the power system, and affects transmission efficiency; it also avoids the problem of charge accumulation. Specifically, it prevents the charge on metal bolts from reaching a certain potential if it cannot be released in time. When the potential is high enough, electrostatic discharge will occur, which may ignite flammable and explosive gases, suspended dust, and combustible mixtures formed by air, leading to fires or even explosions, seriously threatening the safety of cable lines; it also avoids the problem of electric field concentration. Specifically, the sharp edges of suspended metal bolts can cause electric field concentration, increasing the electric field strength in that area. When the electric field strength exceeds the gas breakdown voltage, arc discharge may occur, leading to equipment failure or damage.

[0126] Furthermore, the traditional method of using metal bolts to connect the insulation plate 210 to the side plate 1101 requires a large insulation distance between the metal bolts and the conductive grounding mechanism 220 to overcome the influence of the metal bolts, resulting in a large internal space of the box 100 and a large overall size of the cable grounding box. However, by using the first tenon structure 11211 and the second tenon structure 11221 to connect the insulation plate 210 to the side plate 1101, the insulation distance between the tenon structure and the grounding mechanism 220 does not need to be considered, which can reduce the internal space of the box 100 and thus reduce the size of the cable grounding box.

[0127] The present invention also provides a method for installing the grounding assembly of the cable grounding box in the above embodiments, comprising:

[0128] S100, the first side end of the insulating plate 210 of the grounding assembly 200 is inserted obliquely into the first tenon structure 11211 until the first tenon interface 211 is inserted into the first support part 1121121. When the first side end of the insulating plate 210 is inserted obliquely into the first tenon structure 11211, the distance between the second side end of the insulating plate 210 and the second limiting member 112211 along the width direction of the second side plate 1122 is greater than the distance between the first side end of the insulating plate 210 and the first limiting member 112111 along the width direction of the first side plate 1121.

[0129] S200, during the process of the first tenon 211 being inserted into the first support part 1121121, the second side end of the insulating plate 210 is deflected toward the second limiting member 112211 until the second tenon 212 is inserted into the second support part 1122121.

[0130] S300, a pressure plate 112213 is inserted between the stop block 1122122 and the insulating plate 210;

[0131] S400, using tenon joint 112214 inserted into the insertion port 11221221 of stop block 1122122, pressure plate 112213 and second tenon joint 212.

[0132] Specifically, during the installation of the grounding assembly, firstly, the first side end of the insulating plate 210 of the grounding assembly 200 is inserted obliquely into the first tenon structure 11211 until the first tenon joint 211 is inserted by the first support part 1121121. It should be noted that when the first side end of the insulating plate 210 is inserted obliquely into the first tenon structure 11211, the oblique state of the insulating plate 210 is such that the distance between the second side end of the insulating plate 210 and the second limiting member 112211 along the width direction of the second side plate 1122 is greater than the distance between the first side end of the insulating plate 210 and the first limiting member 112111 along the width direction of the first side plate 1121. Wherein, the first tenon joint 211 is inserted by the first support part 1121121. During the insertion process, the second side end of the insulating plate 210 can be deflected towards the second limiting member 112211 until the second tenon interface 212 allows the second support part 1122121 to be inserted; then, the pressure plate 112213 is inserted between the stop block 1122122 and the insulating plate 210, and the third tenon interface 1122132 on the pressure block allows the second support part 1122121 to be inserted; finally, the tenon post 112214 is inserted through the insertion port 11221221, the insertion hole 1122131 and the second tenon interface 212 of the stop block 1122122, thereby restricting the pressure plate 112213 from coming out from the direction away from the second support part 1122121, and realizing the positioning of the pressure plate 112213. The cable grounding box of the present invention can be assembled without bolts during the assembly of the grounding component 200 into the box body 100, and the entire operation can be completed independently by a single worker, making the operation simple.

[0133] like Figure 16 As shown, the connection structure between cable 300 and grounding assembly 200 is as follows:

[0134] like Figure 16 As shown, the cable 300 can be a coaxial cable, which includes an inner conductor 310 and an outer conductor 320. The inner conductor 310 and the outer conductor 320 are coaxially arranged, and the outer conductor 320 is sleeved on the inner conductor 310. In the section of the cable 300 used to connect to the grounding component 200, the outer layer of the cable 300 is stripped to expose the outer conductor 320. At the same time, in the section of the cable 300 used to connect to the grounding component 200, closer to its end, the outer conductor 320 of the cable 300 and the layer structure between the outer conductor 320 and the inner conductor 310 are further stripped to expose the inner conductor 310.

[0135] like Figure 16As shown, the grounding mechanism 220 includes an inner conductor connection portion 221 and an outer conductor connection portion 222. The inner conductor 310 of the cable 300 is used to connect with the inner conductor connection portion 221, thereby realizing the grounding of the inner conductor 310 of the cable 300. The outer conductor 320 of the cable 300 is used to connect with the outer conductor connection portion 222, thereby realizing the connection of the outer conductor 320 of the cable 300. It should be noted that both the inner conductor connection portion 221 and the outer conductor connection portion 222 are disposed on the insulating plate 210. The insulating plate 210 is used to support the inner conductor connection portion 221 and the outer conductor connection portion 222. Both the inner conductor connection portion 221 and the outer conductor connection portion 222 are made of conductive material and are grounded through other conductive components.

[0136] like Figure 23 As shown, the connection structure between the cable 300 and the grounding assembly 200 includes an inner conductor connection structure 230, which connects the inner conductor 310 of the cable 300 to the inner conductor connection portion 221; wherein, as Figure 16 As shown, the inner conductor connection portion 221 is provided with an inner conductor insertion hole 2211; as Figure 23 , Figure 24 As shown, the inner conductor connection structure 230 includes a first plug-in head 231, a first elastic conductor 232, and a snap ring 233.

[0137] The first plug 231 is used to be sleeved on the outside of the inner conductor 310 of the cable 300.

[0138] Specifically, the first plug 231 is a tubular structure used to be sleeved on the outer side of the inner conductor 310 of the cable 300, wherein the first plug 231 can be interference-fitted with the inner conductor 310.

[0139] It should be noted that the first plug 231 can be made of conductive materials such as copper or aluminum, and the first plug 231 can conduct electricity with the inner conductor 310 of the cable 300.

[0140] Combination Figure 23 and Figure 24 The first elastic conductor 232 is sleeved on the outside of the first plug-in head 231.

[0141] Specifically, the first elastic conductor 232 is fixedly sleeved on the outside of the first plug head 231. The first elastic conductor 232 and the first plug head 231 can be an interference fit. In addition, the first elastic conductor 232 can be made of materials such as copper, copper alloy, aluminum or aluminum alloy, or other materials that are more conductive, such as silver or gold, can be plated on the surface of the above materials to improve the conductivity between the inner conductor 310 and the inner conductor connection part 221.

[0142] Furthermore, the outer peripheral sidewall of the first plug-in head 231 is provided with a first positioning groove, and the first elastic conductor 232 is sleeved in the first positioning groove. The first positioning groove is used to limit the first elastic conductor 232, thereby preventing the first elastic conductor 232 from moving along the axial direction of the first plug-in head 231.

[0143] Understandably, the first plug 231 is used to pass through the inner conductor insertion hole 2211 so that the first elastic conductor 232 abuts against the hole wall of the inner conductor insertion hole 2211. Since the first elastic conductor 232 is elastic, it can abut against the hole wall of the inner conductor insertion hole 2211 under its own elastic force, reducing the risk of it disengaging from the inner conductor connection part 221. In addition, the abutment between the first elastic conductor 232 and the hole wall of the inner conductor insertion hole 2211 can realize the conductive connection between the first elastic conductor 232 and the inner conductor connection part 221, thereby achieving the purpose of conductively connecting the inner conductor 310 and the inner conductor connection part 221.

[0144] It is understood that the inner conductor insertion hole 2211 has an insertion end and an exit end disposed opposite to the insertion end. Specifically, in this embodiment, the lower end of the inner conductor insertion hole 2211 is the insertion end and the upper end is the exit end. When the inner conductor 310 of the cable 300 is connected to the inner conductor connection part 221, the cable 300, the first plug 231 and the first elastic conductor 232 are inserted into the inner conductor insertion hole 2211 from the insertion end. After the cable 300, the first plug 231 and the first elastic conductor 232 are inserted into place, a part of the first plug 231 passes through the exit end of the inner conductor insertion hole 2211. The part of the first plug 231 that passes through the exit end of the inner conductor insertion hole 2211 is defined as the snap-fit ​​part 2311.

[0145] Combination Figure 23 and Figure 25 The snap ring 233 is fitted onto the snap part 2311 and is used to abut against one end of the inner conductor connection part 221 near the through end of the inner conductor insertion hole 2211.

[0146] It is understandable that the outer diameter of the snap ring 233 is larger than the wall of the inner conductor insertion hole 2211. After the snap ring 233 is fitted onto the snap part 2311, it can prevent the first plug-in head 231 from coming out of the inner conductor insertion hole 2211, thereby achieving a reliable connection between the inner conductor 310 of the cable 300 and the inner conductor connection part 221.

[0147] In the connection structure between the cable 300 and the grounding assembly 200 of the present invention, a reliable connection between the inner conductor 310 and the inner conductor connection portion 221 of the cable 300 can be achieved by relying on the inner conductor connection structure 230. Furthermore, this method eliminates the need for bolts to fasten the inner conductor 310 of the cable 300, avoiding the need to grind down the tips of bolts, thus simplifying the connection method.

[0148] Combination Figure 25 and Figure 26 In some embodiments, the edge of the end of the snap-fit ​​part 2311 away from the through end of the inner conductor through hole 2211 is provided with a snap-fit ​​inlet 23111, and the outer peripheral sidewall of the snap-fit ​​part 2311 is provided with an arc-shaped snap groove 23112 with one end communicating with the snap-fit ​​inlet 23111.

[0149] It is understood that the edge of the snap-fit ​​inlet 23111 extends along a direction parallel to the axial direction of the inner conductor insertion hole 2211 from the end of the snap-fit ​​part 2311 away from the outlet end of the inner conductor insertion hole 2211; the arc-shaped snap-fit ​​groove 23112 is formed on the outer peripheral sidewall of the snap-fit ​​part 2311, and the arc-shaped snap-fit ​​groove 23112 is coaxially arranged with the snap-fit ​​part 2311, wherein one end of the arc-shaped snap-fit ​​groove 23112 is connected to the snap-fit ​​inlet 23111.

[0150] Combination Figure 25 and Figure 26 The snap ring 233 includes a ring body 2331 and a snap fastener 2332 disposed on the inner peripheral sidewall of the ring body 2331. The snap fastener 2332 is configured to be able to be screwed into the arc-shaped snap groove 23112 through the snap inlet 23111, so that the ring body 2331 is fitted onto the snap part 2311 and abuts against the end of the inner conductor connection part 221 near the protruding end.

[0151] Understandably, when assembling the snap ring 233, the snap buckle 2332 can be aligned with the snap inlet 23111 first, and then the snap ring 233 can be moved toward the snap part 2311 so that the snap buckle 2332 is inserted into the snap inlet 23111 and aligns with the inlet of the arc-shaped slot 23112. Then the snap ring 233 can be rotated so that the snap ring 233 and the snap part 2311 are engaged together.

[0152] It is also understandable that when connecting the inner conductor 310 of the cable 300 to the inner conductor connection part 221, the cable 300, the first plug 231, and the first elastic conductor 232 are inserted into the inner conductor insertion hole 2211 from the insertion end of the inner conductor insertion hole 2211. After the cable 300, the first plug 231, and the first elastic conductor 232 are inserted into place, the locking part 2311 of the first plug 231 passes through the exit end of the inner conductor insertion hole 2211. By installing a locking ring 233 on the locking part 2311 and making the locking ring 233 abut against the end of the inner conductor connection part 221 near the exit end of the inner conductor insertion hole 2211, the locking ring 233 is equivalent to an inverted structure, which can prevent the cable 300 from slipping out from the insertion end of the inner conductor insertion hole 2211.

[0153] Furthermore, the arc-shaped slot 23112 has an inlet end near the card inlet 23111 and a limiting wall 23113 away from the card inlet 23111. The limiting wall 23113 is in a limiting engagement with the buckle 2332. The limiting wall 23113 is used to limit the rotation angle of the buckle 2332. When the buckle 2332 abuts against the limiting wall 23113, it means that the buckle 2332 is installed in place.

[0154] like Figure 23 , Figure 24 As shown, in some embodiments, the inner conductor connection structure 230 further includes an insulating cover 234, which covers the snap-fit ​​portion 2311 and seals the snap-fit ​​ring 233. It is understood that the insulating cover 234 can seal the snap-fit ​​portion 2311, thereby achieving insulation and improving safety.

[0155] like Figure 27 As shown, the insulating cover 234 further includes a plug 2341 for insertion into the snap-fit ​​inlet 23111.

[0156] Specifically, the insulating cover 234 is made of insulating material, such as insulating rubber or insulating plastic.

[0157] Understandably, the plug 2341 can fill the snap-fit ​​inlet 23111, so that the insulating cover 234, the snap-fit ​​ring 233 and the snap-fit ​​part (first plug-in head 231) form a whole. The three of them achieve circumferential positioning. When the cable 300 rotates, the three of them rotate together, and the snap fastener 2332 on the snap-fit ​​ring 233 will not slip out of the arc-shaped slot 23112 and cause the connection position to fail.

[0158] Combination Figure 23 and Figure 24In some embodiments, the inner conductor connection structure 230 further includes a first insulating member 235, which is sleeved on the outside of the first plug-in head 231. The first insulating member 235 covers the gap between the insertion end of the inner conductor insertion hole 2211 and the first plug-in head 231.

[0159] Specifically, the first insulating member 235 is made of insulating material, such as insulating rubber or insulating plastic. At least a portion of the first insulating member 235 is inserted into the gap between the insertion end of the inner conductor insertion hole 2211 and the first plug-in head 231. On the one hand, this can improve the sealing effect and reduce the risk of the conductor in the conductor insertion hole 2211 being oxidized. On the other hand, it can also achieve insulation and improve safety.

[0160] like Figure 23 As shown, in some embodiments, the connection structure between the cable 300 and the grounding component 200 further includes an outer conductor connection structure 240, which is used to connect the outer conductor 320 of the cable 300 to the outer conductor connection portion 222.

[0161] The outer conductor connection structure 240 includes a second plug 241 and a second elastic conductor 242.

[0162] The second plug 241 is used to be sleeved on the outer conductor 320 of the cable 300.

[0163] Specifically, the second plug 241 is a tubular structure used to be sleeved on the outer conductor 320 of the cable 300, wherein the second plug 241 can be interference-fitted with the outer conductor 320.

[0164] It should be noted that the second plug 241 can be made of conductive materials such as copper or aluminum, and the second plug 241 can conduct electricity with the outer conductor 320 of the cable 300.

[0165] Combination Figure 23 and Figure 28 The second elastic conductor 242 is sleeved on the outside of the second plug head 241.

[0166] Specifically, the second elastic conductor 242 is fixedly sleeved on the outside of the second plug 241. The second elastic conductor 242 and the second plug 241 can be an interference fit. In addition, the second elastic conductor 242 can be made of materials such as copper, copper alloy, aluminum or aluminum alloy, or other materials that are more conductive, such as silver or gold, can be plated on the surface of the above materials to improve the conductivity between the outer conductor 320 and the outer conductor connection part 222.

[0167] Furthermore, the outer peripheral sidewall of the second plug-in head 241 is provided with a second positioning groove, and the second elastic conductor 242 is sleeved in the second positioning groove. The second positioning groove is used to limit the second elastic conductor 242, thereby preventing the second elastic conductor 242 from moving along the axial direction of the second plug-in head 241.

[0168] It should be noted that the outer conductor connection part 222 is used to clamp the second elastic conductor 242, thereby fixing the second elastic conductor 242.

[0169] Combination Figure 16 , Figure 22 and Figure 23 Specifically, the outer conductor connection part 222 is a clamp, which includes a first clamping part 2221 and a second clamping part 2222 rotatably connected to the first clamping part 2221. The first clamping part 2221 and the second clamping part 2222 together clamp the second elastic conductor 242.

[0170] Furthermore, one end of the first clamping part 2221 is rotatably connected to one end of the second clamping part 2222, and the other end of the first clamping part 2221 is rotatably connected to a screw 2223. The other end of the second clamping part 2222 is provided with a limiting groove 22221. The screw 2223 rotates into the limiting groove 22221 and is locked to the second clamping part 2222 by a nut 2224. It should be noted that the nut 2224 is a cap nut 2224. Specifically, the nut 2224 is cap-shaped, and its inner sidewall is provided with threads. When the nut 2224 is connected to the screw 2223, the nut 2224 covers the end of the screw 2223.

[0171] Combination Figure 23 and Figure 28 In some embodiments, the outer conductor connection structure 240 further includes a second insulating member 243, which is sleeved on the outside of the second plug-in head 241.

[0172] Specifically, the second insulating element 243 is made of insulating material, such as insulating rubber or insulating plastic. The second insulating element 243 seals around the end of the second plug 241. On the one hand, it can improve the sealing effect, thereby reducing the risk of oxidation of the relevant conductors in the outer conductor connection 222. On the other hand, it can also achieve insulation and improve safety.
