Description

[0002] The existing distribution network line tension towers include the installation of clamps, crossarms and tension clamps. There are many parts, most of which are connected by bolted clamps or wedge-shaped clamps. The installation is cumbersome and the maintenance is very inconvenient. The jumpers of traditional tension towers increase the line spacing, and the shaking of the leads will cause the distance from the grounding body to be insufficient, which poses a hidden danger. The traditional tension components are not sufficiently insulated, and there are many exposed points on the conductor part, which is easily affected by external factors and causes failures. Due to the low insulation level of the tension components, the conductors need to maintain a large spacing, resulting in the tension lines occupying more space and a larger space range, which is in great conflict with the spatial distance of residential buildings, trees and public facilities.

Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0049] Embodiment 1:

[0050] like Figure 1 As shown, this embodiment provides a tension-resistant wire connection device, including a quick-insert tension-resistant wire clamp 1, a universal joint 2, a current-carrying wire 3, a current-carrying component 4, a clamp 5 and a sealing cover 6.

[0051] The two ends of the through-flow component 4 are respectively provided with quick-insertion tension clamps 1 through the universal joint 2; the clamp 5 is arranged in the middle of the through-flow component 4; and a sealing cover 6 is arranged outside the universal joint 2. The quick-insertion tension clamp 1 is used to connect the wire, and the through-flow wire 3 is used to connect the quick-insertion tension clamp 1 and the through-flow component 4.

[0052] like Figure 2 and Figure 3 As shown, the quick-plug tension clamp 1 includes a quick-plug tension clamp body 102, a wire plug-in assembly 101 and a lead plug-in assembly 103 arranged on the quick-plug tension clamp body 102; the quick-plug tension clamp 1 also includes a first hinged connection hole 104, a first sealing connector 105, a plug-in block 106 and a clamp pressure plate 107.

[0053] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, the wire plug assembly 101 includes two limit blocks 1011 arranged on the wire clamp pressure plate 107 through a torsion spring 1012, and a wire plug 1016 detachably arranged between the two limit blocks 1011.

The setting of the arc-shaped opening 1013 can enable the wire plug 1016 to be quickly inserted into the guide hole 1015; the guide hole 1015 is an arc-shaped tapered hole, which cooperates with the tapered section on the limiting step 1018 to reduce the difficulty of the limiting step 1018 passing through the guide hole 1015; after the first contact 1017 passes through the guide hole 1015, it reaches the plug-in block 106; when the limiting step 1018 passes through the guide hole 1015, the two limiting blocks 1011 are reset under the action of the torsion spring 1012, so that the truncated cone section on the limiting step 1018 is engaged in the limiting circular groove 1014, preventing the wire plug 1016 from loosening or slipping out; the wire connecting hole 1020 is used to connect with the wire, and the end of the wire can be pressed into the wire connecting hole 1020 by clamping or releasing other auxiliary pressure heads and other components.

[0055] like Figure 3 As shown, the lead plug assembly 103 includes a nut 1031 detachably arranged on the quick-insert tension clamp body 102, and a lead plug connector 1032 arranged on the quick-insert tension clamp body 102 through the nut 1031. The nut 1031 can be a nylon nut.

[0057] It can be understood that the quick-plug tension clamp body 102 is provided with a bolt matching the nut 1031, and the bolt is provided with a through hole allowing the lead plug connector 1032 to pass through, and the second contact 1033 passes through the through hole on the bolt and reaches the plug block 106; the annular boss 1034 is engaged in the annular groove 1038 to fix the lead plug connector 1032 and the quick-plug tension clamp body 102; the lead connection hole 1036 is used to connect with the lead, and the end of the lead can be pressed into the lead connection hole 1036 by clamping or releasing other auxiliary pressure heads and other components.

[0058] During operation, after the wire is set in the wire connection hole 1020, the wire plug 1016 is directly inserted between the two limit blocks 1011, and the wire plug 1016 passes through the arc-shaped opening 1013 and the guide hole 1015 in turn, and the two limit blocks 1011 are opened. At this time, the torsion spring 1012 stores energy until the limit step 1018 enters the limit circular groove 1014, and the two limit blocks 1011 are merged under the action of the torsion spring 1012 to achieve the quick plug-in of the wire plug 1016; when the wire plug 1016 is removed, it is only necessary to press the crimping piece 108 to open the two limit blocks 1011 and then pull out the wire plug 1016, thereby improving the construction efficiency of the connection of the wires and the like; at the same time, the lead plug connector 1032 can be quickly installed and disassembled through the nut 1031, thereby improving the construction efficiency of the lead connection.

Specifically, the two ends of the current-carrying wire 3 can be respectively inserted into and connected to the quick-insert tension clamp 1 and the current-carrying component 4 by means of crimped copper rods for line current diversion. A through hole for passing the current-carrying wire 3 can be opened in the middle position of the universal joint 2.

[0064] like Fig.13 and Fig.14 As shown, the flow component 4 also includes a flow component body 401, two plug-in holes 402 arranged in the flow component body 401, a slot 403 arranged on the flow component body 401, and a connector 404 plugged into the slot 403; the two plug-in holes 402 are respectively connected to the two quick-insert tension clamps 1 through the flow conductor 3, and the connector 404 is connected to the two plug-in holes 402.

[0065] Optionally, the plug connector 404 includes an operating rod 4041 and a conducting rod 4042, wherein the operating rod 4041 is made of insulating material and the conducting rod 4042 is a U-shaped structure. Fig.15 As shown, the conducting rod 4042 may include both insulating material and conductive material. When the two plug holes 402 need to be connected, the conductive material connector 404 is inserted into the slot 403, and then the two ends of the conducting rod 4042 are respectively inserted into the preset sockets on the two plug holes 402 to connect the two plug holes 402. When the two plug holes 402 do not need to be connected, the insulating material connector 404 is inserted into the slot 403, and then the two ends of the conducting rod 4042 are respectively inserted into the preset sockets on the two plug holes 402, or the connector 404 is not provided directly.

[0069] In this embodiment, the various parts of the components can be formed in an integrated manner, which further compresses the construction space, shortens the horizontal and vertical spacing of the wires, and improves the space utilization rate; after all the components are pre-installed, only quick plug-in is required during on-site construction to complete the connection of the wires, which improves on-site operation efficiency; the setting of the universal joint 2 is suitable for 0°-90° angle corner towers and wire sagging, etc., and meets the use of multiple working conditions; the quick-plug tension clamp 1 and the flow-through component 4 can adopt an integral die-casting mode, which can not only play an insulating role, but also improve the corrosion resistance of the hardware.
