Description

Technical Field

[0001] The utility model relates to the technical field of cable accessories, in particular to an adjustable stress cone of a cable accessory. Background Art

[0002] In cable terminals and joints, an insulating tape is wrapped around the edge of the metal sheath to form a transition cone from the edge of the metal sheath to the surface of the increased insulation. This component is called a stress cone. The function of the stress cone is to improve the electric field distribution at the end of the metal sheath and reduce the electric field strength at the edge of the metal sheath.

[0003] A stress cone for silicone rubber cable accessories disclosed in the Chinese utility model patent application disclosure CN212726450U includes a device body, a fixing plate, a connecting column and a combination plate. The front of the device body is embedded and connected with the combination plate, the top of the combination plate is fixedly connected with an embedded block, the top of the embedded block is embedded and connected with a connecting column, both sides of the connecting column are embedded and connected with fixing bolts, the bottom end of the fixing bolt is embedded and connected with a nut, one side of the nut is fixedly connected with an insulating block, and the middle of the combination plate is fixedly connected with a fixing plate. Since the existing stress cone for silicone rubber cable accessories does not have a good protection and fixing device, we add a fixing plate and a card plate to the device body, and fix the fixing plate and the card plate with the connecting bolt by rotating the knob, so that the sealing and fixing effect of the combination plate in the device body is better, and the current overflow phenomenon will not occur. At the same time, the device body can be reinforced to prevent it from being damaged by external collision.

[0004] However, the device has the function of clamping cables. When in use, the device cannot fix cables of different sizes, which causes a lot of trouble, so that the cables are easy to shake in the device. Moreover, the device lacks the function of facilitating installation. When in use, the device cannot be quickly installed and disassembled, which causes a lot of trouble, making it inconvenient for the staff to work. Utility Model Content
