Abstract
Description
Technical Field
[0001] This application relates to the field of high-voltage cable technology, and in particular to a high-voltage cable and power supply equipment. Background Technology
[0002] High-voltage cables serve as channels for high-voltage power output. They typically require plug-and-play connections for rapid load connection, while ensuring the strength and reliability of the connection between the cable and the load end to guarantee the safe and stable operation of the high-voltage system and prevent issues such as leakage, disconnection, and creepage. In related technologies, high-voltage cables usually have a braided layer (01) and a sheath layer (02). The braided layer, generally made of metal, primarily serves to provide electromagnetic shielding, grounding protection, enhance mechanical strength, and uniform electric field distribution. The sheath layer mainly buffers external impacts and protects the internal materials of the high-voltage cable. Figure 1 As shown, in related technologies, a metal sleeve 03 is typically used to fit onto the metal braided layer 01, and a common hydraulic clamp is used to clamp the metal sleeve 03 to generate deformation, so as to press the metal braided layer 01 onto the sheath layer 02.
[0003] The inventors of this application have discovered that during the manufacturing process of high-voltage cables, if dimensional issues arise and the position of the metal clamp needs to be readjusted, the clamping force of the metal clamp becomes fixed due to deformation caused by the hydraulic clamp, making it difficult to adjust the position of the metal clamp. In this case, the manufactured high-voltage cable can only be scrapped, resulting in high modification costs and inconvenience. Utility Model Content

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0021] Please see Figure 2 and Figure 3The high-voltage cable 1000 includes a conductor 10, an insulation layer 20, a sheath layer 30, a braided layer 40, a collet 50, and a locking assembly 60. The insulation layer 20 covers at least a portion of the outer surface of the conductor 10, the sheath layer 30 covers at least a portion of the outer surface of the insulation layer 20, the braided layer 40 covers at least a portion of the outer surface of the sheath layer 30, the collet 50 is at least partially fitted onto the outer surface of the braided layer 40, the braided layer 40 is located between the collet 50 and the sheath layer 30, and the locking assembly 60 is at least partially fitted onto the outer surface of the collet 50. The locking assembly 60 is used to adjust the clamping force exerted by the collet 50 on the braided layer 40.
[0022] The high-voltage cable 1000 also includes a mating sleeve 70, a first mating plug 80, and a second mating plug 90. The mating sleeve 70 is detachably fitted onto the end of the collet 50 away from the locking assembly 60. The first mating plug 80 is connected to one end of the conductor 10, and the second mating plug 90 is connected to the other end of the conductor 10. The conductor 10, insulation layer 20, sheath layer 30, braided layer 40, collet 50, locking assembly 60, mating sleeve 70, first mating plug 80, and second mating plug 90 are described in detail below.
[0023] For the aforementioned conductor 10, insulation layer 20, sheath layer 30, and braided layer 40, as Figure 2 and Figure 3 As shown, the insulation layer 20 covers at least a portion of the outer surface of the conductor 10, the sheath layer 30 covers at least a portion of the outer surface of the insulation layer 20, and the braided layer 40 covers at least a portion of the outer surface of the sheath layer 30. The conductor 10 mainly functions to transmit electrical energy and carry current. The insulation layer 20 serves to insulate, preventing current leakage from the conductor 10 and reducing the impact of the external environment on the conductor 10. The sheath layer 30 can buffer external impacts, protect the internal materials, and also provide waterproofing, moisture resistance, chemical corrosion resistance, flame retardancy, and fire prevention, reducing the damage to the high-voltage cable 1000 caused by the external environment. The braided layer 40 serves to provide electromagnetic shielding, grounding protection, enhance mechanical strength, and uniform electric field distribution. It is understood that the materials used to make conductor 10 include, but are not limited to, copper, aluminum, aluminum alloy, copper alloy or tin-plated copper, etc.; the materials used to make insulation layer 20 include, but are not limited to, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), cross-linked polyethylene (XLPE), ethylene propylene rubber (EPR), silicone rubber, etc.; the materials used to make sheath layer 30 include, but are not limited to, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), neoprene rubber (CR), ethylene propylene rubber (EPR), silicone rubber, etc.; and the materials used to make braided layer 40 include, but are not limited to, tin-plated copper wire, bare copper wire, nickel-plated copper wire, steel wire / iron wire, etc.
[0024] For the aforementioned collet 50 and locking assembly 60, such as Figure 3 and Figure 4 As shown, the collet 50 is at least partially fitted onto the outer surface of the braided layer 40, which is located between the collet 50 and the sheath layer 30. The collet 50 is used to stably constrain the braided layer 40 onto the sheath layer 30 to reduce the risk of the braided layer 40 falling off. The locking component 60 is at least partially fitted onto the outer surface of the collet 50 and is used to adjust the clamping force exerted by the collet 50 on the braided layer 40. When it is necessary for the collet 50 to clamp the braided layer 40, the user only needs to use the locking component 60 to increase the clamping force exerted by the collet 50 on the braided layer 40. When it is necessary to adjust the position of the collet 50, the user only needs to use the locking component 60 to decrease the clamping force exerted by the collet 50 on the braided layer 40. After the clamping force exerted by the collet 50 on the braided layer 40 is reduced to a preset value, the position of the collet 50 can be adjusted.
[0025] Please refer to the following for details. Figure 5 The locking assembly 60 includes a first clamping block 601, a second clamping block 602, and a connector 603. The first clamping block 601 and the second clamping block 602 are connected by the connector 603. The first clamping block 601 is provided with a first cavity 601a, and the second clamping block 602 is provided with a second cavity 602a. The first cavity 601a and the second cavity 602a enclose to form a locking cavity 60b. At least a portion of the collet 50 is located within the locking cavity 60b. A portion of the braided layer 40 abuts against the first clamping block 601 and the second clamping block 602. The first clamping block 601 and the second clamping block 602 are spaced apart by a certain distance. The first gap 60a is adjusted by the connector 603 to regulate the clamping force of the collet 50 on the braided layer 40. When the collet 50 needs to clamp the braided layer 40, the user simply rotates the connector 603 to gradually decrease the first gap 60a, thereby increasing the clamping force. Conversely, when the collet 50 needs to release the braided layer 40, the user simply rotates the connector 603 to gradually increase the first gap 60a, thereby decreasing the clamping force. It should be noted that the first clamping block 601 and the second clamping block 602 not only clamp the collet 50 but also clamp a portion of the outer surface of the braided layer 40, thus making the braided layer 40 more stably confined to the outer surface of the sheath layer 30. In some embodiments, the connector 603 is a screw, rivet, or other connecting structure.
[0026] In some embodiments, please refer to the following: Figure 6The outer surface of the collet 50 is provided with an annular groove 501. The inner wall of the first clamping block 601 extends radially with a first limiting protrusion 6011, which is located at the edge of the first clamping block 601 and is engaged in the annular groove 501. The inner wall of the second clamping block 602 extends radially with a second limiting protrusion 6021, which is located at the edge of the second clamping block 602 and is arranged opposite to the first limiting protrusion 6011. The second limiting protrusion 6021 is engaged in the annular groove 501. By using the first limiting protrusion 6011 and the second limiting protrusion 6021 to engage in the annular groove 501, the upward movement of the collet 50 along the axial direction can be reduced.
[0027] In some embodiments, there are multiple annular grooves 501, which are spaced upward along the axial direction of the collet 50. The inner wall of the first clamping block 601 is radially recessed with a first clearance space 601b, and the inner wall of the second clamping block 602 is radially recessed with a second clearance space 602b. The first clearance space 601b and the second clearance space 602b together form a clearance groove 60c. When the first limiting protrusion 6011 and the second limiting protrusion 6021 are engaged with one of the annular grooves 501, a portion of the collet 50 is located in the clearance groove. Within 60c, the clearance groove 60c provides clearance space for the collet 50 to move upward along the axial direction. The user can engage the first limiting protrusion 6011 and the second limiting protrusion 6021 in different annular grooves 501 to adjust the overall length of the collet 50 and the locking assembly 60 along the axial direction. At the same time, it can adjust the different force points of contact between the locking assembly 60 and the collet 50. The user can engage the first limiting protrusion 6011 and the second limiting protrusion 6021 in different annular grooves 501 according to actual needs. No specific limitation is made in this application.
[0028] In some embodiments, the inner wall of the first clamping block 601 has a plurality of third limiting protrusions 6012 extending radially, the plurality of third limiting protrusions 6012 being spaced upward along the axial direction of the collet 50, and the plurality of third limiting protrusions 6012 abutting against the upper surface of the braided layer 40. The inner wall of the second clamping block 602 has a plurality of fourth limiting protrusions 6022 extending radially, the plurality of fourth limiting protrusions 6022 being spaced upward along the axial direction of the collet 50, and the plurality of fourth limiting protrusions 6022 abutting against the lower surface of the braided layer 40. The third limiting protrusions 6012 and the fourth limiting protrusions 6022 together abut against the outer surface of the braided layer 40, so that the braided layer 40 is more stably bound to the sheath layer 30. In some embodiments, both the third limiting protrusions 6012 and the fourth limiting protrusions 6022 are arc-shaped protrusions.
[0029] In some embodiments, please refer to the following: Figure 7The first clamping block 601 is provided with a first connecting hole 6013 and a second connecting hole 6014. The first connecting hole 6013 is located at one end of the first clamping block 601, and the second connecting hole 6014 is located at the other end of the first clamping block 601. The second clamping block 602 is provided with a third connecting hole 6023 and a fourth connecting hole 6024. The third connecting hole 6023 is located at one end of the second clamping block 602, and the fourth connecting hole 6024 is located at the other end of the second clamping block 602. The third connecting hole 6023 is opposite to the first connecting hole 6013, and the fourth connecting hole 6024 is opposite to the first connecting hole 6014. Two connecting holes 6014 are arranged opposite to each other. The connector 603 includes a first connector 6031 and a second connector 6032. The first connector 6031 passes through the first connecting hole 6013 and the third connecting hole 6023, thereby connecting one end of the first clamping block 601 and one end of the second clamping block 602. The second connector 6032 passes through the second connecting hole 6014 and the fourth connecting hole 6024, thereby connecting the other end of the first clamping block 601 and the other end of the second clamping block 602, thus achieving the connection between the first clamping block 601 and the second clamping block 602.
[0030] It is understood that in some other embodiments, one end of the first clamping block 601 and one end of the second clamping block 602 are rotatably connected, and the other end of the first clamping block 601 and the other end of the second clamping block 602 are detachably connected by a connector 603.
[0031] It should be noted that the first clamping block 601 and the second clamping block 602 have the same structure. When installing the first clamping block 601 and the second clamping block 602, the user does not need to distinguish between the types of clamping blocks. There is no need to worry about the two parts looking similar and making it easy to pick the wrong parts, which would affect production efficiency. In addition, the fact that the first clamping block 601 and the second clamping block 602 have the same structure also makes it convenient to prepare goods in batches and save on mold opening costs.
[0032] For the aforementioned mating sleeve 70, first mating plug 80, and second mating plug 90, as Figure 3 and Figure 4 As shown, the mating sleeve 70 is detachably fitted onto the end of the collet 50 opposite to the locking assembly 60. The mating sleeve 70 and the locking assembly 60 are spaced upwards along the axial direction of the collet 50. The first mating plug 80 is connected to one end of the conductor 10, and the second mating plug 90 is connected to the other end of the conductor 10. One of the first mating plug 80 and the second mating plug 90 is connected to an external power supply device, and the other is connected to an external load, thereby enabling the voltage and current of the power supply device to be transmitted to the load through the high-voltage cable 1000. The end of the mating sleeve 70 opposite to the collet 50 can be used to connect to the connection port on the external power supply device to stably fix the high-voltage cable 1000 to the power supply device.
[0033] In this embodiment, a conductor 10, an insulation layer 20, a sheath layer 30, a braided layer 40, a collet 50, and a locking assembly 60 are provided. The insulation layer 20 covers at least a portion of the outer surface of the conductor 10, the sheath layer 30 covers at least a portion of the outer surface of the insulation layer 20, the braided layer 40 covers at least a portion of the outer surface of the sheath layer 30, the collet 50 is at least partially fitted onto the outer surface of the braided layer 40, the braided layer 40 is located between the collet 50 and the sheath layer 30, and the locking assembly 60 is at least partially fitted onto the outer surface of the collet 50. The locking assembly 60 is used to adjust the clamping force of the collet 50 on the braided layer 40. With this configuration, during the manufacturing process of the high-voltage cable 1000, when it is necessary for the collet 50 to clamp the braided layer 40, the user only needs to use the locking assembly 60 to increase the clamping force of the collet 50. The clamping force applied to the braided layer 40 can be adjusted by the user using the locking component 60 to reduce the clamping force of the collet 50 on the braided layer 40 when the position of the collet 50 needs to be adjusted. After the clamping force of the collet 50 on the braided layer 40 is reduced to a preset value, the position of the collet 50 can be adjusted. Compared with the fixed clamping force of the metal sleeve in related technologies, in this embodiment, the clamping force of the collet 50 on the braided layer 40 can be adjusted according to actual needs using the locking component 60, and the position of the collet 50 can also be adjusted according to actual needs. This can reduce the scrapping of high-voltage cables 1000, save manufacturing costs, and is more convenient.
[0034] This application also provides an embodiment of a power supply device, which includes the high-voltage cable 1000 as described above. The function and structure of the high-voltage cable 1000 can be found in the above embodiments, and will not be repeated here.
[0035] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
