Technical Field

[0001] The present invention relates to the technical field of connection fittings, in particular to a high-voltage electric wire connection fitting that is easy to install and fatigue-resistant. Background Art

[0002] Power lines are used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. When installing power lines at high altitudes, we usually use power fittings to fix them in place. Power fittings are metal accessories that connect and combine various devices in the power system, and serve to transmit mechanical loads, electrical loads, and provide some protection. When installing current high-voltage power lines, the power fittings must first be installed on power towers or poles, and then the high-voltage power lines must be installed on the power fittings.

[0003] At present, some existing electrical fittings use a two-piece installation and fixing method when installing and fixing wires, using bolts to fix the two pieces of fittings. During long-term use, the wires located at high altitudes will continue to shake due to the influence of external forces. During the shaking, the fittings will vibrate, causing the bolts to loosen, affecting the stability of the wires. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the present invention provides a high-voltage wire connecting hardware that is easy to install and fatigue-resistant, including a first connecting hardware and a second connecting hardware that are completely identical in structure and symmetrically installed, a clamping piece installation groove is provided at the center position of the outer end portion of the first connecting hardware and the second connecting hardware, and the first clamping piece and the second clamping piece are respectively threadedly connected in the clamping piece installation grooves of the first connecting hardware and the second connecting hardware; the outer sides of the first clamping piece and the second clamping piece are provided with operating grooves respectively located on the first connecting hardware and the second connecting hardware, the connecting part of the first connecting hardware and the second connecting hardware is a connecting block, and the connecting blocks of the first connecting hardware and the second connecting hardware are respectively provided with through screw holes, and are fixed by first fixing screws and second fixing screws respectively.

[0006] Preferably, the structures of the first clamping member and the second clamping member are exactly the same, and both are composed of deformation blocks that are connected in a ring shape at the bottom and spaced apart at the upper ends. The outer side of the deformation block is provided with a thread that matches the inner side of the clamping member installation groove; the middle parts of the first clamping member and the second clamping member are both wire insertion grooves, and the upper end outer diameter of the first clamping member and the second clamping member is larger than the lower end outer diameter.

[0007] Preferably, conductive sheets are provided on the inner sides of the deformation blocks, which can effectively improve the conductive effect of the wire fittings.

[0008] Preferably, a rotating operating lever is symmetrically provided on the upper end of the deformation block, which can facilitate the operator to install the first clamping member and the second clamping member in the corresponding clamping member installation grooves of the first connecting hardware and the second connecting hardware.

[0009] Preferably, the inner sides of the connecting blocks of the first connecting fitting and the second connecting fitting are both provided with positioning grooves, and the outer ends are provided with positioning blocks matching the positioning grooves.

[0010] Preferably, one side of the screw hole opening is provided with a screw mounting platform, which can effectively improve the installation stability of the first fixing screw and the second fixing screw and prevent them from falling off easily in the later stage.

[0024] Example 1

[0025] like Figure 1 As shown, the present invention provides a fatigue-resistant, easy-to-install high-voltage wire connection fitting, comprising a first connection fitting 1 and a second connection fitting 2, both of which are identical in structure and symmetrically mounted. This design facilitates installation, eliminating the need to distinguish and identify the fitting structures on both sides, thereby improving installation efficiency. Furthermore, during production, only one set of molds is required, eliminating the need to create separate molds for fittings of varying structures as is common in most existing technologies. This design significantly reduces production costs.

[0026] A clamping piece installation groove 3 is provided at the center position of the outer end portion of the first connecting hardware 1 and the second connecting hardware 2. The inner walls of the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 are provided with threads. The first clamping piece 5 and the second clamping piece 6 are respectively threadedly connected in the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2. The first clamping piece 5 and the second clamping piece 6 can be manually screwed into the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 respectively.

[0027] like Figure 2 As shown, the first clamping member 5 and the second clamping member 6 have identical structures. This design can further reduce costs by reducing the number of molds required. Both the first clamping member 5 and the second clamping member 6 consist of a deformable block 51, connected in a circular pattern at the bottom and separated at the top. This structural design allows the top ends of the deformable blocks 51 to deform more easily. The outer sides of the deformable blocks 51 are threaded to match the inner sides of the clamping member mounting slot 3, facilitating a more secure installation within the clamping member mounting slot 3.

[0028] A rotating operating lever 53 is symmetrically provided at the upper end of the deformation block 51, which can be convenient for the operator to pick up and provide a position for the fingers to apply force during the installation of the first clamping member 5 and the second clamping member 6, so that the operator can tighten the first clamping member 5 and the second clamping member 6 in the clamping member installation groove 3 to prevent the first clamping member 5 and the second clamping member 6 from easily falling off from the clamping member installation groove 3, which is beneficial to improving the stability of the subsequent wire connection.

[0029] The outer sides of the first clamping member 5 and the second clamping member 6 are respectively provided with operating grooves 4 located on the first connecting hardware 1 and the second connecting hardware 2. The width of the operating groove 4 is slightly larger than the total length of the first clamping member 5 or the second clamping member 6, so that the operator can more smoothly place the first clamping member 5 and the second clamping member 6 into the clamping member installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 and fix them.

[0030] The middle parts of the first clamping member 5 and the second clamping member 6 are both wire insertion slots 54. During the installation process, the wire conductor 8 of the wire 7 needs to be inserted into the wire insertion slot 54. The inner side of the deformation block 51 is provided with a conductive sheet 52. The full contact between the conductive sheet 52 and the wire conductor 8 can effectively improve the conductive effect of the wire fittings. In addition, in order to ensure that the fittings do not affect the conductivity of the wire 7 after connection, the first clamping member 5, the second clamping member 6, the first connecting fitting 1 and the second connecting fitting 2 are all made of highly conductive materials, such as copper, aluminum, etc. In actual application, the fittings of corresponding materials can be selected according to the connection of different power wires 7, while ensuring the connection effect and reducing the installation cost as much as possible.

[0031] The outer diameter of the upper end of the first clamping member 5 and the second clamping member 6 is larger than the outer diameter of the lower end, while the inner diameter of the clamping member mounting groove 3 on the first connecting hardware 1 and the second connecting hardware 2 is consistent. Therefore, during the installation process, you only need to first pass the wire conductor 8 of the wire 7 through the clamping member mounting groove 3 on the first connecting hardware 1 or the second connecting hardware 2, and then insert it into the wire insertion groove 54 of the first clamping member 5 or the second clamping member 6, manually place the first clamping member 5 and the second clamping member 6 at the connection ports of the clamping member mounting groove 3 of the first connecting hardware 1 and the second connecting hardware 2 respectively, and screw the first clamping member 5 and the second clamping member 6 into the corresponding clamping member mounting groove 3 by manually adjusting the rotating operating lever 53.

[0032] During the rotation process, the outer ends of the deformation blocks 51 of the first clamping member 5 and the second clamping member 6 will gradually shrink inward under the pressure of the inner wall of the clamping member mounting groove 3, thereby driving the conductive sheet 52 on the inner wall of the first clamping member 5 and the second clamping member 6 to gradually clamp the wire conductor 8, thereby achieving the fixation of the end of the wire 7. Moreover, since the friction force exerted by the wire conductors 8 of the wires 7 at both ends on the first clamping member 5 and the second clamping member 6 respectively is the same as the installation direction of the first clamping member 5 and the second clamping member 6, the downward pulling force exerted by the wire 7 itself on the hardware will also drive the first clamping member 5 and the second clamping member 6 to move toward the inside of the clamping member installation groove 3 of the first connecting hardware 1 or the second connecting hardware 2 respectively. The more the first clamping member 5 and the second clamping member 6 move toward the inside of the clamping member installation groove 3, the greater the deformation blocks 51 of the first clamping member 5 and the second clamping member 6 deform inward, thereby increasing the clamping force on the wire conductor 8. Therefore, the downward pulling force of the wires 7 at both ends will also drive the clamping force of the first clamping member 5 and the second clamping member 6 on the wire conductor 8 to a certain extent, making the wire hardware in this embodiment have higher fatigue resistance, so there is no need to worry about the problem of loosening in the later stage.

[0033] Through the mutual cooperation between the first clamping member 5 and the first connecting fitting 1, and the mutual cooperation between the second clamping member 6 and the second connecting fitting 2, the clamping and fixing ability of the wire fittings at both ends to the wires can be guaranteed first.

[0034] The connecting portion of the first connecting hardware 1 and the second connecting hardware 2 is a connecting block 9, and the connecting blocks of the first connecting hardware 1 and the second connecting hardware 2 are respectively provided with through screw holes 13, and are fixed by first fixing screws 14 and second fixing screws 15, such as Figure 3 and Figure 4 The first connecting fitting 1 and the second connecting fitting 2 are also made of conductive materials as a whole, so there will be no poor contact after connection.

[0035] The outer ends of the first and second fixing screws 14, 15 are fixed to the second connecting fitting 2 and the first connecting fitting 1, respectively, in a centrally symmetrical arrangement. Securing the first and second connecting fittings 1, 2 from opposite sides can theoretically further enhance the stability of the connection. During actual installation, applying glue to the outer surfaces of the first and second fixing screws 14, 15 before installing can further enhance stability and prevent them from falling off.

[0036] like Figure 5 As shown, one side of the opening of the screw hole 13 is set as a screw mounting platform 12. Since the screw mounting platform 12 is a plane, it can ensure that the first fixing screw 14 and the second fixing screw 15 are tightly contacted with the outer surfaces of the corresponding second connecting hardware 2 and the first connecting hardware 1 respectively, which can increase the contact area, thereby improving the installation stability of the first fixing screw 14 and the second fixing screw 15.

[0037] Example 2

[0038] like Figure 6 As shown, the present invention provides a fatigue-resistant, easy-to-install high-voltage wire connection fitting, comprising a first connection fitting 1 and a second connection fitting 2, both of which are identical in structure and symmetrically mounted. This design facilitates installation, eliminating the need to distinguish and identify the fitting structures on both sides, thereby improving installation efficiency. Furthermore, during production, only one set of molds is required, eliminating the need to create separate molds for fittings of varying structures as is common in most existing technologies. This design significantly reduces production costs.

[0039] A clamping piece installation groove 3 is provided at the center position of the outer end portion of the first connecting hardware 1 and the second connecting hardware 2. The inner walls of the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 are provided with threads. The first clamping piece 5 and the second clamping piece 6 are respectively threadedly connected in the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2. The first clamping piece 5 and the second clamping piece 6 can be manually screwed into the clamping piece installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 respectively.

[0040] like Figure 2 As shown, the first clamping member 5 and the second clamping member 6 have identical structures. This design can further reduce costs by reducing the number of molds required. Both the first clamping member 5 and the second clamping member 6 consist of a deformable block 51, connected in a circular pattern at the bottom and separated at the top. This structural design allows the top ends of the deformable blocks 51 to deform more easily. The outer sides of the deformable blocks 51 are threaded to match the inner sides of the clamping member mounting slot 3, facilitating a more secure installation within the clamping member mounting slot 3.

[0041] A rotating operating lever 53 is symmetrically provided at the upper end of the deformation block 51, which can be convenient for the operator to pick up and provide a position for the fingers to apply force during the installation of the first clamping member 5 and the second clamping member 6, so that the operator can tighten the first clamping member 5 and the second clamping member 6 in the clamping member installation groove 3 to prevent the first clamping member 5 and the second clamping member 6 from easily falling off from the clamping member installation groove 3, which is beneficial to improving the stability of the subsequent wire connection.

[0042] The outer sides of the first clamping member 5 and the second clamping member 6 are respectively provided with operating grooves 4 located on the first connecting hardware 1 and the second connecting hardware 2. The width of the operating groove 4 is slightly larger than the total length of the first clamping member 5 or the second clamping member 6, so that the operator can more smoothly place the first clamping member 5 and the second clamping member 6 into the clamping member installation grooves 3 of the first connecting hardware 1 and the second connecting hardware 2 and fix them.

[0043] The middle parts of the first clamping member 5 and the second clamping member 6 are both wire insertion slots 54. During the installation process, the wire conductor 8 of the wire 7 needs to be inserted into the wire insertion slot 54. The inner side of the deformation block 51 is provided with a conductive sheet 52. The conductive sheet 52 is in full contact with the wire conductor 8, which can effectively improve the conductive effect of the hardware. In addition, in order to ensure that the hardware does not affect the conductivity of the wire 7 after connection, the first clamping member 5, the second clamping member 6, the first connecting hardware 1 and the second connecting hardware 2 are all made of highly conductive materials, such as copper, aluminum, etc. In actual application, hardware of corresponding materials can be selected according to the connection of different power wires 7, while ensuring the connection effect and reducing the installation cost as much as possible.

[0044] The outer diameter of the upper end of the first clamping member 5 and the second clamping member 6 is larger than the outer diameter of the lower end, while the inner diameter of the clamping member mounting groove 3 on the first connecting hardware 1 and the second connecting hardware 2 is consistent. Therefore, during the installation process, you only need to first pass the wire conductor 8 of the wire 7 through the clamping member mounting groove 3 on the first connecting hardware 1 or the second connecting hardware 2, and then insert it into the wire insertion groove 54 of the first clamping member 5 or the second clamping member 6, manually place the first clamping member 5 and the second clamping member 6 at the connection ports of the clamping member mounting groove 3 of the first connecting hardware 1 and the second connecting hardware 2 respectively, and screw the first clamping member 5 and the second clamping member 6 into the corresponding clamping member mounting groove 3 by manually adjusting the rotating operating lever 53.

[0045] During the rotation process, the outer ends of the deformation blocks 51 of the first clamping member 5 and the second clamping member 6 will gradually shrink inward under the pressure of the inner wall of the clamping member mounting groove 3, thereby driving the conductive sheet 52 on the inner wall of the first clamping member 5 and the second clamping member 6 to gradually clamp the wire conductor 8, thereby achieving the fixation of the end of the wire 7. Moreover, since the friction force exerted by the wire conductors 8 of the wires 7 at both ends on the first clamping member 5 and the second clamping member 6 respectively is the same as the installation direction of the first clamping member 5 and the second clamping member 6, the downward pulling force exerted by the wire 7 itself on the hardware will also drive the first clamping member 5 and the second clamping member 6 to move toward the inside of the clamping member installation groove 3 of the first connecting hardware 1 or the second connecting hardware 2 respectively. The more the first clamping member 5 and the second clamping member 6 move toward the inside of the clamping member installation groove 3, the greater the deformation blocks 51 of the first clamping member 5 and the second clamping member 6 deform inward, thereby increasing the clamping force on the wire conductor 8. Therefore, the downward pulling force of the wires 7 at both ends will also drive the clamping force of the first clamping member 5 and the second clamping member 6 on the wire conductor 8 to a certain extent, making the wire hardware in this embodiment have higher fatigue resistance, so there is no need to worry about the problem of loosening in the later stage.

[0046] Through the mutual cooperation between the first clamping member 5 and the first connecting fitting 1, and the mutual cooperation between the second clamping member 6 and the second connecting fitting 2, the clamping and fixing ability of the wire fittings at both ends to the wires can be guaranteed first.

[0047] The connecting portion of the first connecting hardware 1 and the second connecting hardware 2 is a connecting block 9, and the connecting blocks of the first connecting hardware 1 and the second connecting hardware 2 are respectively provided with through screw holes 13, and are fixed by first fixing screws 14 and second fixing screws 15, such as Figure 3 and Figure 6 shown.

[0048] In this embodiment, the inner sides of the connecting blocks 9 of the first connecting hardware 1 and the second connecting hardware 2 are both provided with positioning grooves 10, and the outer ends are provided with positioning blocks 11 that match the positioning grooves 10. Figure 6 The corresponding matching of the positioning groove 10 and the positioning block 11 not only facilitates the rapid positioning and connection of the first connecting hardware 1 and the second connecting hardware 2, but also effectively prevents the first connecting hardware 1 and the second connecting hardware 2 from falling off laterally, which is beneficial to improving the stability of the connection between the hardware. The first connecting hardware 1 and the second connecting hardware 2 are also made of conductive materials as a whole, so there will be no poor contact after connection.

[0049] The outer ends of the first and second fixing screws 14, 15 are fixed to the second connecting fitting 2 and the first connecting fitting 1, respectively, in a centrally symmetrical arrangement. Securing the first and second connecting fittings 1, 2 from opposite sides can theoretically further enhance the stability of the connection. During actual installation, applying glue to the outer surfaces of the first and second fixing screws 14, 15 before installing can further enhance stability and prevent them from falling off.

[0050] like Figure 5 As shown, one side of the opening of the screw hole 13 is set as a screw mounting platform 12. Since the screw mounting platform 12 is a plane, it can ensure that the first fixing screw 14 and the second fixing screw 15 are tightly contacted with the outer surfaces of the corresponding second connecting hardware 2 and the first connecting hardware 1 respectively, which can increase the contact area, thereby improving the installation stability of the first fixing screw 14 and the second fixing screw 15.

[0051] Therefore, the present invention adopts the above-mentioned easy-to-install and fatigue-resistant high-voltage wire connection hardware, which has a simple structure, is easy to produce and install, and can also effectively improve the stability of the wire connection, achieve a fixing effect that becomes tighter as it is pulled, and prevent the wires from easily falling off in the later stage.
