Description

Technical Field

[0001] This utility model relates to the field of high-voltage line shielding pressure ring technology, and more specifically to a high-voltage line shielding tensile shielding pressure ring structure. Background Technology

[0002] With the rapid development of power systems and the widespread application of electrical equipment, high-voltage cables, as an important part of power transmission, are facing increasingly complex operating environments. In order to ensure the stable operation and transmission efficiency of high-voltage cables, effective shielding measures are needed to resist external electromagnetic interference, and shielding ring structures have emerged as a result.

[0003] The existing high-voltage line shielding method generally uses copper foil to cover the folded shielding wire, and then uses heat shrink tubing to control the exposed size of the shielding. However, when this structure is used in the special installation environment of the whole vehicle, it may be subjected to local stress, and the adhesion of the wire alone is not enough, which can easily cause the wire to be pulled off.

[0004] Furthermore, existing shielding rings are often directly replaced during subsequent maintenance. When installing a new shielding ring, the shielding layer needs to be reconnected to the shielding ring, and it is necessary to ensure that the connection between the shielding layer and the shielding ring is tight and secure again. The whole process is relatively troublesome.

[0005] To address the aforementioned issues, this application provides a high-voltage line shielding tensile shielding ring structure. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-voltage line shielding tensile shielding pressure ring structure to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a high-voltage line shielding tensile shielding ring structure, including a high-voltage main line and a collar assembly installed on the high-voltage main line, wherein a fixing component and a tensile component are installed on the collar assembly, and a connecting component is installed between the tensile component and the high-voltage main line;

[0008] Preferably, the high-voltage main line includes a metal conductor, an inner insulation layer, a shielding layer, and an outer insulation layer, wherein the surface of the metal conductor is wrapped from the inside out by the inner insulation layer, the shielding layer, and the outer insulation layer in sequence.

[0009] Preferably, the collar assembly includes a main collar, a connecting piece, a first connector, a first screw, and a grounding wire. The main collar is movably sleeved on the outer surface of the inner insulation layer. The connecting piece is disposed on the lower side of the inner insulation layer and fixedly installed on the main collar. The first connector is snapped onto the connecting piece. The threaded end of the first screw movably passes through the first connector and then threadedly snaps onto the connecting piece. The right end of the grounding wire is electrically connected to the first connector.

[0010] Preferably, the fixing component includes a positioning block, a second screw, a pusher, and a push block. The main collar is provided with four fixing components arranged in a circular pattern. The positioning block is fixedly installed on the main collar. The threaded end of the second screw passes through the positioning block. The pusher is fixedly sleeved on the threaded end of the second screw. The push block rotates and sleeves the pusher. At this time, the second screw is rotated. Under the action of threaded engagement, multiple second screws move closer to the central axis of the main collar. At the same time, the push block rotated and sleeved on the pusher is also driven to contract towards the central axis of the main collar and squeeze the surface of the inner insulation layer, thereby fixing the collar assembly as a whole on the high-voltage main line.

[0011] Preferably, the tensile component includes a limiting block, a spring, a movable column, a limiting ring, and a metal clip. Four tensile components arranged in a circular pattern are fixedly installed on the main collar. The limiting block is fixedly installed on the main collar. The movable column is movably engaged with the limiting block. The spring is located on the left side of the limiting block and movably sleeved on the spring. The limiting ring is located on the right side of the limiting block and fixedly sleeved on the spring. The metal clip is fixedly installed on the right end of the spring. When the high-voltage main line is pulled, the shielding layer is pulled to the right, and simultaneously the movable column is pulled to the right. At this time, the spring sleeved on the movable column is compressed, giving the movable column a force to the left, preventing the shielding layer from being pulled off.

[0012] Preferably, the connecting assembly includes a connector, a third screw, a second connector, a fourth screw, and a connecting wire. The connector is snapped onto the right side of the metal block. The threaded end of the third screw passes through the connector and is threaded onto the metal block. The second connector is snapped between two limiting pieces on the connector and is movably snapped onto the fourth screw. The threaded end of the fourth screw is threaded onto the two limiting pieces. One end of the connecting wire is electrically connected to the second connector, and the other end is electrically connected to a portion of the bundled wire group of the shielding layer. At this time, rotating the third and fourth screws fixes the connecting assembly between the metal block and the shielding layer. The shielding layer is electrically connected to the metal block through the connector.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The design of the tensile component allows the shielding layer to exert a continuous opposing force at the connection point when it is pulled, preventing the internal shielding layer from being pulled off and losing its shielding effect when the high-voltage line is pulled by external force. At the same time, the design of the collar assembly and the connecting assembly allows the shielding layer to be directly connected to the collar assembly through the connecting assembly when replacing the new shielding collar, which facilitates the subsequent maintenance and replacement of the collar.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high-voltage line shielding tensile shielding pressure ring structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides a high-voltage line shielding tensile shielding ring structure, including a high-voltage main line 1 and a collar assembly 2 installed on the high-voltage main line 1. A fixing assembly 3 and a tensile assembly 4 are installed on the collar assembly 2, and a connecting assembly 5 is installed between the tensile assembly 4 and the high-voltage main line 1.

[0022] Reference Figure 2 The high-voltage main line 1 includes a metal conductor 101, an inner insulation layer 102, a shielding layer 103 and an outer insulation layer 104, wherein the surface of the metal conductor 101 is wrapped from the inside out by the inner insulation layer 102, the shielding layer 103 and the outer insulation layer 104 in sequence.

[0023] Reference Figure 1The collar assembly 2 includes a main collar 201, a connecting piece 202, a first connector 203, a first screw 204, and a grounding wire 205. The main collar 201 is movably sleeved on the outer surface of the inner insulation layer 102. The connecting piece 202 is disposed on the lower side of the inner insulation layer 102 and fixedly installed on the main collar 201. The first connector 203 is snapped onto the connecting piece 202. The threaded end of the first screw 204 moves through the first connector 203 and then snaps onto the connecting piece 202. The right end of the grounding wire 205 is electrically connected to the first connector 203.

[0024] Reference Figure 2 and Figure 3 The fixing component 3 includes a positioning block 301, a second screw 302, a pusher head 303, and a pusher block 304. The main collar 201 is provided with four fixing components 3 arranged in a circular pattern. The positioning block 301 is fixedly installed on the main collar 201. The threaded end of the second screw 302 passes through the positioning block 301. The pusher head 303 is fixedly sleeved on the threaded end of the second screw 302. The pusher block 304 is rotated and sleeved on the pusher head 303. At this time, the second screw 302 is rotated. Under the action of the threaded engagement, multiple second screws 302 move closer to the central axis of the main collar 201. At the same time, the pusher block 304, which is rotated and sleeved on the pusher head 303, is also driven to shrink towards the central axis of the main collar 201 and squeeze the surface of the inner insulation layer 102, thereby fixing the collar assembly 2 as a whole on the high voltage main line 1.

[0025] Reference Figure 1 The tensile component 4 includes a limiting block 401, a spring 402, a moving column 403, a limiting ring 404, and a metal clip 405. Four tensile components 4 are fixedly installed on the main collar 201 in a circular arrangement. The limiting block 401 is fixedly installed on the main collar 201. The moving column 403 is movably clipped onto the limiting block 401. The spring 402 is located on the left side of the limiting block 401 and is movably sleeved on the spring 402. The limiting ring 404 is located on the right side of the limiting block 401 and is fixedly sleeved on the spring 402. The metal clip 405 is fixedly installed on the right end of the spring 402. When the high-voltage main line 1 is pulled, the shielding layer 103 is pulled to the right. At the same time, the moving column 403 is driven to be pulled to the right. At this time, the spring 402 sleeved on the moving column 403 is compressed and a force to the left is applied to the moving column 403 to prevent the shielding layer 103 from being pulled off.

[0026] Reference Figure 2 and Figure 4The connecting component 5 includes a connector 501, a third screw 502, a second connector 503, a fourth screw 504, and a connecting wire 505. The connector 501 is snapped onto the right side of the metal block 405. The threaded end of the third screw 502 passes through the connector 501 and is threaded onto the metal block 405. The second connector 503 is snapped between two limiting pieces on the connector 501 and is movably snapped onto the fourth screw 504. The threaded end of the fourth screw 504 is threaded onto the two limiting pieces. One end of the connecting wire 505 is electrically connected to the second connector 503, and the other end is electrically connected to a portion of the bundled wire group of the shielding layer 103. At this time, rotating the third screw 502 and the fourth screw 504 fixes the connecting component 5 between the metal block 405 and the shielding layer 103. The shielding layer 103 is electrically connected to the metal block 405 through the connector 501.

[0027] The working principle of this utility model is as follows: When installing the shielding ring, the main collar 201 is placed on the inner insulation layer 102, and the second screw 302 is rotated. At this time, under the action of the threaded engagement, multiple second screws 302 move closer to the central axis of the main collar 201. At the same time, the push block 304, which is rotated and sleeved on the push head 303, is also driven to retract towards the central axis of the main collar 201 and squeeze the surface of the inner insulation layer 102, thereby fixing the collar assembly 2 as a whole onto the high-voltage main line 1. Then, by rotating the third screw 502 and the fourth screw 504, the connecting assembly 5 is fixedly installed. Between the metal clip 405 and the shielding layer 103, the shielding layer 103 is electrically connected to the metal clip 405 through the connector 501. Since the entire components of the collar assembly 2 and the tensile assembly 4 are made of metal and are conductive, the shielding layer 103 is electrically connected to the grounding wire 205. When the high-voltage main line 1 is pulled, the shielding layer 103 is pulled to the right, and at the same time, the moving column 403 is driven to be pulled to the right. At this time, the spring 402 sleeved on the moving column 403 is compressed and gives the moving column 403 a force to the left to prevent the shielding layer 103 from being pulled off.
