Description

Technical Field

[0001] The present invention relates to the technical field of electric power fittings, and in particular to an electric power connection fitting. Background Art

[0002] Cables installed outdoors in the power sector are usually installed overhead using power connection hardware to prevent them from being damaged on the ground and affecting their use.

[0003] The Chinese patent application with publication number "CN118943990A" discloses "a double suspension wire clamp, comprising a suspension plate and a sling, wherein the lower end of the sling is rotatably connected to the middle of the suspension plate; further comprising two wire clamp assemblies, two rotating shafts, a swing arm 1, a swing arm 2 and a pull rod, wherein the two wire clamp assemblies are used to clamp the cables, and the middle of the two wire clamp assemblies are both equipped with a rotating shaft". Although it can achieve the effect of "its double vertical wire clamps always maintain an eight-shaped relative arrangement, which reduces the bending damage of the cables when the cables are subjected to unbalanced force and has good practicality", its arrangement method makes the cables always maintain an eight-shaped arrangement after overhead installation, which can reduce bending damage. Bend, but the outdoor terrain is complex and diverse. When the terrain shows a continuous downward and upward trend, adjacent utility poles are not in the same horizontal position, which causes the wire installation to be inclined downward or upward. The cable overhead installation line will undergo different left and right and up and down transitions as the terrain changes. This patent makes the cable installation only suitable for use in areas with flat terrain, and its use has limitations.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

The ball bearings allow the cables to rotate through the arc-shaped cable support tube even after being fixed, preventing the cables from being affected by external factors after being completely fixed. This can prevent the cables from contacting the connecting fittings under torque, causing surface cracks and impacting their use.

[0019] 2. The setting of the downward pressure component is conducive to limiting the outer top of the cable, which can prevent the cable from being scratched when bending upward. The side limit component and the wire clamping structure can limit the outer sides of the cable to prevent the cable from directly contacting the connecting hardware. It can also prevent scratches when the cable swings left and right, thereby increasing the service life.

[0020] 3. By setting up an adjustment structure in conjunction with the wire clamping structure, it is beneficial to further restrict and lift the cable, which can ensure the stability of the cable overhead installation. At the same time, the cable installed with the connection hardware can change the installation state according to the needs of the outdoor terrain, which can better adapt to the changes in the outdoor terrain and help improve its work adaptability. The adjustment component and the adjustment structure can change the installation angle of the cable as needed to cope with complex outdoor terrain changes;

[0021] 4. By setting a buffer limit structure and cooperating with the wire clamping structure, the outer bottom of the cable can be restricted and lifted. At the same time, the spring three and the telescopic rod can buffer the downward pressure of the cable on the buffer roller, relieve the downward pressure on the cable and protect the outer bottom of the cable;

[0022] 5. By setting the plug-in assembly in conjunction with the buffer limit structure, it is helpful to limit the position of the movable seat 2, so that the buffer roller can obtain support force and improve the lifting effect on the outer bottom of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

The two storage racks 29 are connected by the protrusions 31 at the corresponding positions and the U-shaped fastener 32.

[0050] The adjustment structure 3 cooperates with the wire clamping structure 2 to further restrict and support the cable, ensuring the stability of the overhead cable installation. At the same time, it allows the cable installed with the connecting hardware to change the installation status according to the needs of the outdoor terrain, which can better adapt to changes in the outdoor terrain and help improve its work adaptability.

[0051] In this embodiment, the adjustment structure 3 also includes an adjustment component, which includes a fixed frame 2 33 and an arc-shaped baffle 34.

[0059] In this embodiment, two groups of plug-in components are provided on the outside of the mounting plate 6, and the plug-in components include two hollow tubes 44.

[0061] It should be noted that the present invention is a power connection hardware. Before use, several connection hardware are installed on the corresponding outdoor electric poles to make it reach the working condition. The connection hardware can be divided into multiple usage states according to different outdoor terrains. Figure 1 is the initial state of the connection hardware;

[0062] Usage status 1: When several connecting hardware are used on flat outdoor terrain and the distance between two adjacent electric poles is not far, install the suspension plate 1 on the outdoor electric pole. After the suspension plate 1 is installed, install the upper base 7 on the mounting plate 6 through the bolt fastener 1 8, place the cable on the inner side of the circular inner wall formed by the two arc-shaped wire-supporting tubes 12, install the two arc-shaped wire-supporting tubes 12 on the inner side of the lower base 9, and connect the lower base 9 and the upper base 7 through the bolt fastener 2 10, so that the two arc-shaped wire-supporting tubes 12 are restricted to the inside of the circular inner wall formed by the upper base 7 and the lower base 9, and the outer surface of the arc-shaped wire-supporting tube 12 fits with the surface of the ball 11. When the cable shakes, the arc-shaped wire-supporting tube 12 will rotate inside the upper base 7 and the lower base 9 under the action of the several balls 11, preventing the cable from shaking. After being fixed, the surface of the cable is affected by the torsional force due to shaking and is broken. At this time, the cable is lifted, and the outer surface of the cable contacts and is restricted by the surface of the wire roller 14 inside the arc-shaped wire supporting tube 12. Remove the U-shaped fastener 32, place the cable between the two wire rollers 30, and then fix the distance between the two wire rollers 30 through the U-shaped fastener 32, so that the wire rollers 30 and the surface of the cable contact and restrict and lift them. Pull out the rod 46 from the inside of the hollow tube 44, rotate the movable frame three 38 and move the movable seat two 42 to a position matching the hollow tube 44, release the operating handle 47, and under the action of the spring three 49, insert the rod 46 into the movable seat two 42 and the inner side of the hollow tube 44 and restrict the position of the movable seat two 42, so that the connecting hardware is finally achieved as shown in the figure. Figure 1 In the initial state, the outer top of the cable is restricted under the action of spring 1 20 and pressing roller 2 19, and the outer sides of the cable are restricted by the corresponding pressing roller 3 23. Under the action of spring 3 49 and telescopic rod 41, the buffer roller 39 restricts and lifts the outer bottom of the cable. When the cable is subjected to force, the buffer roller 39 cooperates with spring 3 49 and telescopic rod 41 to buffer the cable, and the overhead installation of the cable can be completed. Since the two adjacent poles are spaced apart and on the same horizontal plane, the cable is achieved. Figure 1 After the initial state, the cable is straightened and can be used;

[0063] Usage status 2: When several connecting hardware are used on a flat outdoor terrain and the distance between two adjacent electric poles is large, due to the large distance, the cable between the two adjacent electric poles will form a concave curve under the action of its own weight, which will increase the downward pressure of the contact part between the cable and the connecting hardware, making the local position of the cable easily damaged. On the basis of usage status 1, remove the bolt fastener 3 26 and the bolt fastener 4 28, rotate the adjustment frame 25 and the movable frame 2 27 until the adjustment frame 25 and the movable frame 2 27 rotate to a predetermined angle and then stop, and fix the position of the adjustment frame 25 and the movable frame 2 27 by the bolt fastener 3 26 and the bolt fastener 4 28. At this time, the cable between the two U-shaped fasteners 32 forms an eight-shaped shape, and the buffer roller 39 will buffer the downward pressure on the cable under the action of the spring 2 43 and the telescopic rod 41. At the same time, the wire roller 30 of the two sets of adjustment structures 3 limits and lifts the cable according to the curved shape of the cable to further alleviate the downward pressure on the cable;

[0064] Usage state three: When several connecting hardware are used on electric poles on uneven ascending or descending terrain, the cables need to be in an inclined state. Based on the usage state one, the bolt fastener three 26 and the bolt fastener four 28 are removed, and the adjusting frame 25 and the movable frame two 27 are rotated until the adjusting frame 25 and the movable frame two 27 are rotated to a predetermined angle and then stopped. The positions of the adjusting frame 25 and the movable frame two 27 are fixed by the bolt fastener three 26 and the bolt fastener four 28. At this time, the two sets of adjustment structures 3 form an S shape with the cable between the two U-shaped fasteners 32. The cable on the ascending or descending terrain can better adapt to the changes in the terrain height, and avoid the cable being directly pulled up or down, which causes the contact part of the cable and the connecting hardware to be subjected to excessive force and cause rupture, thereby improving the working adaptability of the connecting hardware and the service life of the cable;

[0065] Usage scenario four: When one of the electric poles is at the junction of rising terrain and flat terrain or at the junction of falling terrain and flat terrain, the connecting hardware on the electric pole is required to set one end of the installed cable upward or downward according to the rising or falling terrain, while the cable at the other end should be installed parallel to the flat terrain. Based on the usage scenario one, the bolt fasteners 3 26 and the bolt fasteners 4 28 of one set of the adjustment structure 3 are removed, and the adjustment frame 25 and the movable frame 2 27 are rotated until the adjustment frame 25 and the movable frame 2 27 are rotated to a predetermined angle and then stopped. The positions of the adjustment frame 25 and the movable frame 2 27 are fixed by the bolt fasteners 3 26 and the bolt fasteners 4 28. At this time, the cable on one side of the connecting hardware is set upward or downward according to the rising or falling terrain, while the cable on the other side is set parallel to the ground according to the flat terrain.

[0066] In addition, when the cable is installed outdoors, not only the vertical height will change, but the horizontal angle will also change due to the installation route. When the direction of cable installation needs to be changed, Figure 1 On the basis of this, remove the screw 36, rotate the fixing frame 2 33 clockwise or counterclockwise to a predetermined angle, and then fix the fixing frame 2 33 with the screw 36. At the same time, since the setting of the wire pressing roller 3 23 will limit the cable on both sides of the outside, when the cable turns, the cable will not be scratched by the connecting hardware.
