[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] Typically, a grounding component is installed inside the grounding box, and grounding is achieved by connecting the grounding cable to the grounding component. In related technologies, the connection between the inner conductor of the grounding cable and the grounding cable usually requires the use of bolts. However, tightening the bolts is relatively troublesome. In addition, the bolts need to be de-sharpened to avoid sharp point discharge. Utility Model Content

After the cable, the first plug, and the first elastic conductor are in place, a locking ring is fitted onto the locking part and abuts against the end of the inner conductor connection part near the exit end of the inner conductor insertion hole. Because the first elastic conductor is elastic, it can abut against the wall of the inner conductor insertion hole under its own elastic force, reducing the risk of it detaching from the inner conductor connection part. Furthermore, the abutment between the first elastic conductor and the wall of the inner conductor insertion hole enables conductive connection between the first elastic conductor and the inner conductor connection part, thereby achieving the purpose of conductively connecting the inner conductor to the inner conductor connection part. Furthermore, the snap-fit ​​ring, once fitted onto the snap-fit ​​portion, prevents the first plug from dislodging from the inner conductor insertion hole, thus ensuring a reliable connection between the inner conductor and the inner conductor connection portion of the cable. In the cable and grounding assembly connection structure of this invention, a reliable connection between the inner conductor and the inner conductor connection portion of the cable can be achieved through the inner conductor connection structure. Moreover, this method avoids the need for metal bolts to secure the inner conductor of the cable, and eliminates the need to grind down the bolt tips, simplifying the connection process.

[0020] The cable grounding box of this utility model has the above-mentioned connection structure between the cable and the grounding component. In the connection structure, the inner conductor connection structure is used to connect the inner conductor of the cable to the inner conductor connection part. When connecting the inner conductor of the cable to the inner conductor connection part, the cable, the first plug, and the first elastic conductor are inserted into the inner conductor insertion hole from the insertion end. After the cable, the first plug, and the first elastic conductor are inserted into place, the locking ring is fitted onto the locking part and abuts against the end of the inner conductor connection part near the exit end of the inner conductor insertion hole. Because the first elastic conductor is elastic, it can abut against the wall of the inner conductor insertion hole under its own elastic force, reducing the risk of it detaching from the inner conductor connection part. Furthermore, the abutment between the first elastic conductor and the wall of the inner conductor insertion hole enables conductive connection between the first elastic conductor and the inner conductor connection part, thereby achieving the purpose of conductive connection between the inner conductor and the inner conductor connection part. Furthermore, the snap-fit ​​ring, once fitted onto the snap-fit ​​portion, prevents the first plug from dislodging from the inner conductor insertion hole, thus ensuring a reliable connection between the inner conductor and the inner conductor connection portion of the cable.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figure 1 As shown, this utility model provides a connection structure between a cable 200 and a grounding component 100 according to an embodiment.

[0043] like Figure 1 As shown, the cable 200 can be a coaxial cable 200, which includes an inner conductor 210 and an outer conductor 220. The inner conductor 210 and the outer conductor 220 are coaxially arranged, and the outer conductor 220 is sleeved on the inner conductor 210. In the section of the cable 200 used to connect to the grounding component 100, the outer layer of the cable 200 is stripped to expose the outer conductor 220. At the same time, in the section of the cable 200 used to connect to the grounding component 100, closer to its end, the outer conductor 220 of the cable 200 and the layer structure between the outer conductor 220 and the inner conductor 210 are further stripped to expose the inner conductor 210.

[0044] Combination Figure 1 and Figure 2 The grounding assembly 100 includes an inner conductor connection portion 120 and an outer conductor connection portion 130. The inner conductor 210 of the cable 200 is used to connect with the inner conductor connection portion 120, thereby grounding the inner conductor 210 of the cable 200. The outer conductor 220 of the cable 200 is used to connect with the outer conductor connection portion 130, thereby connecting the outer conductor 220 of the cable 200. It should be noted that both the inner conductor connection portion 120 and the outer conductor connection portion 130 are disposed on the insulating plate 110. The insulating plate 110 is used to support the inner conductor connection portion 120 and the outer conductor connection portion 130. Both the inner conductor connection portion 120 and the outer conductor connection portion 130 are made of conductive material and are grounded through other conductive components.

[0045] like Figure 5 As shown, the connection structure between the cable 200 and the grounding assembly 100 includes an inner conductor connection structure 300, which is used to connect the inner conductor 210 of the cable 200 to the inner conductor connection part 120; wherein, the inner conductor connection part 120 is provided with an inner conductor insertion hole 121; the inner conductor connection structure 300 includes a first plug 310, a first elastic conductor 320 and a snap ring 330.

[0046] The first plug 310 is used to be sleeved on the outside of the inner conductor 210 of the cable 200.

[0047] Specifically, the first plug 310 is a tubular structure used to be sleeved on the outer side of the inner conductor 210 of the cable 200, wherein the first plug 310 can be interference-fitted with the inner conductor 210.

[0048] It should be noted that the first plug 310 can be made of conductive materials such as copper or aluminum, and the first plug 310 can conduct electricity with the inner conductor 210 of the cable 200.

[0049] Combination Figure 5 and Figure 6 The first elastic conductor 320 is sleeved on the outside of the first plug-in head 310.

[0050] Specifically, the first elastic conductor 320 is fixedly sleeved on the outside of the first plug head 310. The first elastic conductor 320 and the first plug head 310 can be an interference fit. In addition, the first elastic conductor 320 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 210 and the inner conductor connection part 120.

[0051] Furthermore, the outer peripheral sidewall of the first plug-in head 310 is provided with a first positioning groove, and the first elastic conductor 320 is sleeved in the first positioning groove. The first positioning groove is used to limit the first elastic conductor 320, thereby preventing the first elastic conductor 320 from moving along the axial direction of the first plug-in head 310.

[0052] It is understood that the first plug 310 is used to pass through the inner conductor insertion hole 121 so that the first elastic conductor 320 abuts against the hole wall of the inner conductor insertion hole 121. Since the first elastic conductor 320 is elastic, it can abut against the hole wall of the inner conductor insertion hole 121 under its own elastic force, reducing the risk of it disengaging from the inner conductor connection part 120. In addition, the abutment between the first elastic conductor 320 and the hole wall of the inner conductor insertion hole 121 can realize the conductive connection between the first elastic conductor 320 and the inner conductor connection part 120, thereby achieving the purpose of conductively connecting the inner conductor 210 and the inner conductor connection part 120.

[0053] It is understood that the inner conductor insertion hole 121 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 121 is the insertion end and the upper end is the exit end. When the inner conductor 210 of the cable 200 is connected to the inner conductor connection part 120, the cable 200, the first plug 310 and the first elastic conductor 320 are inserted into the inner conductor insertion hole 121 from the insertion end. After the cable 200, the first plug 310 and the first elastic conductor 320 are inserted into place, a part of the first plug 310 passes through the exit end of the inner conductor insertion hole 121. The part of the first plug 310 that passes through the exit end of the inner conductor insertion hole 121 is defined as the snap-fit ​​part 311.

[0054] Combination Figure 5 and Figure 7 The snap ring 330 is fitted onto the snap part 311 and is used to abut against one end of the inner conductor connection part 120 near the through end of the inner conductor insertion hole 121.

[0055] It is understandable that the outer diameter of the snap ring 330 is larger than the wall of the inner conductor insertion hole 121. After the snap ring 330 is fitted onto the snap part 311, it can prevent the first plug-in head 310 from coming out of the inner conductor insertion hole 121, thereby achieving a reliable connection between the inner conductor 210 of the cable 200 and the inner conductor connection part 120.

[0056] In the connection structure between the cable 200 and the grounding component 100 of this utility model, a reliable connection between the inner conductor 210 and the inner conductor connection part 120 of the cable 200 can be achieved by relying on the inner conductor connection structure 300. Furthermore, this method avoids the use of metal bolts to fasten the inner conductor 210 of the cable 200, and avoids the operation of grinding down the tip of the bolt, thus simplifying the connection method.

[0057] Combination Figure 7 and Figure 8 In some embodiments, the edge of the snap-fit ​​part 311 away from the through end of the inner conductor through hole 121 is provided with an insertion port 3111, and the outer peripheral sidewall of the snap-fit ​​part 311 is provided with an arc-shaped slot 3112 with one end communicating with the insertion port 3111.

[0058] It is understood that the edge of the insertion port 3111 extends along the direction parallel to the axial direction of the inner conductor insertion hole 121 from the end of the snap-fit ​​portion 311 away from the outlet end of the inner conductor insertion hole 121; the arc-shaped slot 3112 is formed on the outer peripheral sidewall of the snap-fit ​​portion 311, and the arc-shaped slot 3112 is coaxially arranged with the snap-fit ​​portion 311, wherein one end of the arc-shaped slot 3112 is connected to the insertion port 3111.

[0059] Combination Figure 8 and Figure 9The snap ring 330 includes a ring body 331 and a snap fastener 332 disposed on the inner peripheral sidewall of the ring body 331. The snap fastener 332 is configured to be screwed into the arc-shaped slot 3112 through the insertion port 3111 so that the ring body 331 is fitted onto the snap part 311 and abuts against the end of the inner conductor connection part 120 near the protruding end.

[0060] Understandably, when assembling the snap ring 330, the snap 332 can be aligned with the insertion port 3111 first, and then the snap ring 330 can be moved toward the snap part 311 so that the snap 332 is inserted into the insertion port 3111 and faces the entrance of the arc-shaped slot 3112. Then the snap ring 330 can be rotated so that the snap ring 330 and the snap part 311 are engaged together.

[0061] It is also understandable that when connecting the inner conductor 210 of the cable 200 to the inner conductor connection part 120, the cable 200, the first plug 310, and the first elastic conductor 320 are inserted into the inner conductor insertion hole 121 from the insertion end. After the cable 200, the first plug 310, and the first elastic conductor 320 are in place, the locking part 311 of the first plug 311 passes through the exit end of the inner conductor insertion hole 121. By installing a locking ring 330 on the locking part 311 and making the locking ring 330 abut against the end of the inner conductor connection part 120 near the exit end of the inner conductor insertion hole 121, the locking ring 330 is equivalent to an inverted structure, which can prevent the cable 200 from slipping out from the insertion end of the inner conductor insertion hole 121.

[0062] Furthermore, the arc-shaped slot 3112 has an inlet end near the insertion port 3111 and a limiting wall 3113 away from the insertion port 3111. The limiting wall 3113 is in a limiting engagement with the buckle 332. The limiting wall 3113 is used to limit the rotation angle of the buckle 332. When the buckle 332 abuts against the limiting wall 3113, it means that the buckle 332 is installed in place.

[0063] like Figure 5 , Figure 6 and Figure 10 As shown, in some embodiments, the inner conductor connection structure 300 further includes an insulating cover 340, which covers the snap-fit ​​portion 311 and seals the snap-fit ​​ring 330. It is understood that the insulating cover 340 can seal the snap-fit ​​portion 311, thereby achieving insulation and improving safety.

[0064] Furthermore, the interior of the insulating cover 340 is provided with a plug 341 for insertion into the insertion port 3111.

[0065] Specifically, the insulating cover 340 is made of insulating material, such as insulating rubber or insulating plastic.

[0066] Understandably, the plug 341 can fill the insertion port 3111 completely. In this way, the insulating cover 340, the snap ring 330, and the fastening part (first insertion head 310) form a whole. The three of them achieve circumferential positioning. When the cable 200 rotates, the three of them rotate together. The snap 332 on the snap ring 330 will not slip out of the arc-shaped slot 3112 and cause the connection position to fail.

[0067] Combination Figure 5 and Figure 6 In some embodiments, the inner conductor connection structure 300 further includes a first insulating member 350, which is sleeved outside the first plug-in head 310 and covers the gap between the insertion end of the inner conductor insertion hole 121 and the first plug-in head 310.

[0068] Specifically, the first insulating member 350 is made of insulating material, such as insulating rubber or insulating plastic. At least a portion of the first insulating member 350 is inserted into the gap between the insertion end of the inner conductor insertion hole 121 and the first plug-in head 310. On the one hand, this can improve the sealing effect and reduce the risk of the conductor inside the conductor insertion hole 121 being oxidized. On the other hand, it can also achieve insulation and improve safety.

[0069] like Figure 5 As shown, in some embodiments, the connection structure between the cable 200 and the grounding component 100 further includes an outer conductor connection structure 400, which is used to connect the outer conductor 220 of the cable 200 to the outer conductor connection portion 130.

[0070] The outer conductor connection structure 400 includes a second plug 410 and a second elastic conductor 420.

[0071] The second plug 410 is used to be sleeved on the outer conductor 220 of the cable 200.

[0072] Specifically, the second plug 410 is a tubular structure used to be sleeved on the outer conductor 220 of the cable 200, wherein the second plug 410 can be interference-fitted with the outer conductor 220.

[0073] It should be noted that the second plug 410 can be made of conductive materials such as copper or aluminum, and the second plug 410 can conduct electricity with the outer conductor 220 of the cable 200.

[0074] Combination Figure 5 and Figure 11 The second elastic conductor 420 is sleeved on the outside of the second plug-in head 410.

[0075] Specifically, the second elastic conductor 420 is fixedly sleeved on the outside of the second plug 410. The second elastic conductor 420 and the second plug 410 can be an interference fit. In addition, the second elastic conductor 420 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 220 and the outer conductor connection part 130.

[0076] Furthermore, the outer peripheral sidewall of the second plug-in head 410 is provided with a second positioning groove, and the second elastic conductor 420 is sleeved in the second positioning groove. The second positioning groove is used to limit the second elastic conductor 420, thereby preventing the second elastic conductor 420 from moving along the axial direction of the second plug-in head 410.

[0077] It should be noted that the outer conductor connection portion 130 is used to clamp the second elastic conductor 420, thereby fixing the second elastic conductor 420.

[0078] Combination Figure 3 , Figure 4 and Figure 5 Specifically, the outer conductor connection part 130 is a clamp, which includes a first clamping part 131 and a second clamping part 132 rotatably connected to the first clamping part 131. The first clamping part 131 and the second clamping part 132 together clamp the second elastic conductor 420.

[0079] Furthermore, one end of the first clamping part 131 is rotatably connected to one end of the second clamping part 132, and the other end of the first clamping part 131 is rotatably connected to a screw 133. The other end of the second clamping part 132 is provided with a groove 1321, and the screw 133 rotates into the groove 1321 and is locked to the second clamping part 132 by a nut 134. It should be noted that the nut 134 is a cap nut. Specifically, the nut 134 is cap-shaped, and its inner sidewall is provided with threads. When the nut 134 is connected to the screw 133, the nut 134 covers the end of the screw 133.

[0080] Combination Figure 5 and Figure 11 In some embodiments, the outer conductor connection structure 400 further includes a second insulating member 430, which is sleeved on the outside of the second plug 410.

[0081] Specifically, the second insulating element 430 is made of insulating material, such as insulating rubber or insulating plastic. The second insulating element 430 seals around the end of the second plug 410. 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 130. On the other hand, it can also achieve insulation and improve safety.

[0082] This utility model also provides a cable grounding box, including the connection structure between the cable 200 and the grounding component 100 in the above embodiment.

[0083] The cable grounding box of this utility model has the connection structure of the cable 200 and the grounding component 100 described above. In the connection structure of the cable 200 and the grounding component 100, the inner conductor connection structure 300 is used to connect the inner conductor 210 of the cable 200 to the inner conductor connection part 120. When connecting the inner conductor 210 of the cable 200 to the inner conductor connection part 120, the cable 200, the first plug 310 and the first elastic conductor 320 are inserted into the inner conductor insertion hole 121 from the insertion end of the inner conductor insertion hole 121. After the cable 200, the first plug 310 and the first elastic conductor 320 are inserted into place, the snap ring 330 is sleeved on the snap ring 311 and abuts against the end of the inner conductor connection part 120 near the exit end of the inner conductor insertion hole 121. In this invention, the first elastic conductor 320, being elastic, can abut against the wall of the inner conductor insertion hole 121 under its own elastic force, reducing the risk of it detaching from the inner conductor connection portion 120. Furthermore, the abutment between the first elastic conductor 320 and the wall of the inner conductor insertion hole 121 enables a conductive connection between the first elastic conductor 320 and the inner conductor connection portion 120, thereby achieving the purpose of conductively connecting the inner conductor 210 and the inner conductor connection portion 120. Additionally, the snap ring 330, after being fitted onto the snap ring 311, prevents the first plug-in head 310 from dislodging from the inner conductor insertion hole 121, thus ensuring a reliable connection between the inner conductor 210 and the inner conductor connection portion 120 of the cable 200. In the connection structure of the cable 200 and the grounding component 100 of this invention, the inner conductor connection structure 300 enables a reliable connection between the inner conductor 210 and the inner conductor connection portion 120 of the cable 200. Furthermore, this method avoids the need to use metal bolts to fasten the inner conductor 210 of the cable 200, and avoids the operation of grinding down the tip of the bolt, making the connection method simple.
