Description

Technical Field

[0001] This application relates to a single ear for circuit assembly. Background Technology

[0002] The main functions of line fittings include connecting transmission line towers, conductors, lightning rods, and insulators, as well as protecting these components. Among line fittings, designs vary depending on the application. One type is the single-ear fitting, which refers to a single clamping structure. Existing single-ear structures use a vertical tube to mount the clamping component. This method is difficult to assemble and easily damaged by impacts. Furthermore, it can only be manufactured using casting, which is prone to localized defects, environmentally unfriendly, and has poor safety standards. Utility Model Content

[0003] To address the aforementioned issues, this application proposes a single lug for line assembly, comprising a central partition plate, a connecting sleeve on one side of the central partition plate, and two opposing first and second vertical lug plates on the opposite side of the central partition plate away from the connecting sleeve. A first transverse through hole is provided on the first vertical lug plate, and a second transverse through hole is provided on the second vertical lug plate. A positioning bolt is positioned between the first and second transverse through holes. This application integrates the connecting sleeve, the first vertical lug plate, and the second vertical lug plate into a single unit via the central partition plate. The connecting sleeve connects to the support rod, while the first and second vertical lug plates, together with the positioning bolt, secure the cable. The overall structure boasts high strength and good safety. The open-sided design provides a structural basis for forging. Furthermore, the structure of this application is suitable for forging processes, which are environmentally friendly and offer good processing safety.

[0004] Preferably, the intermediate partition is a rectangular plate, and the outermost edge of the connecting sleeve is flush with the outermost edge of the rectangular plate.

[0005] Preferably, the connecting sleeve is a polygonal tube or a round tube, and a tapered guide edge is provided on the outward-facing inner side of the connecting sleeve.

[0006] Preferably, the center of the connecting sleeve is flush with the center of the intermediate partition.

[0007] Preferably, the cross-sectional areas of the first and second vertical ear plates gradually decrease in the direction away from the middle partition; the first vertical ear plate has a first arc-shaped outer edge on the side away from the middle partition; and the second vertical ear plate has a second arc-shaped outer edge on the side away from the middle partition. The first and second vertical ear plates of this application adopt a gradually changing cross-sectional area, which ensures the reliability of the bottom cable clamping and facilitates cable insertion during clamping construction.

[0008] Preferably, the positioning bolt includes a fixing block disposed on the side of the first vertical ear plate away from the second vertical ear plate. The fixing block abuts against the outer side of the first vertical ear plate. A screw body is disposed on the fixing block, and the screw body passes through the first and second transverse through holes. A locking hole is disposed at the end of the screw body away from the fixing block, and a locking rod is disposed in the locking hole. This application uses the screw body and locking rod in cooperation, which simplifies assembly. The screw body itself can be selected as rod-shaped or arc-shaped as needed, thereby facilitating the fixing and clamping of cables as required.

[0009] Preferably, the locking rod includes a U-shaped connecting buckle, and a first extension rod and a second extension rod are respectively provided on both sides of the U-shaped connecting buckle, and a protruding snap-fit ​​portion is provided on the first extension rod and / or the second extension rod.

[0010] This application can bring the following beneficial effects:

[0011] 1. This application integrates the connecting sleeve, the first vertical ear plate, and the second vertical ear plate into one unit through a middle partition plate. The connecting sleeve is used to connect the support rod part, while the first vertical ear plate and the second vertical ear plate are used together with positioning bolts to fix the cable. The overall structure has high strength and good safety. The open setting on both sides provides a structural basis for forging.

[0012] 2. The first and second vertical ear plates of this application adopt a gradually changing cross-sectional area, which can ensure the reliability of the bottom clamping of the cable and facilitate the insertion of the cable during clamping construction.

[0013] 3. This application uses a screw body and a locking rod in combination, which makes assembly simple. The screw body itself can be selected as rod-shaped or arc-shaped as needed, so that the cable can be conveniently fixed and clamped as needed. Attached Figure Description
