Description

Technical Field

[0001] The utility model relates to the technical field of stress cone structures, in particular to a stress cone structure. Background Art

[0002] The stress cone is a component that is wrapped with insulating tape from the edge of the metal sheath in the cable terminal and joint, so that a transition cone is formed between the edge of the metal sheath and the surface of the wound insulation. 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] The utility model with announcement number CN211428887U discloses a stress cone structure, including a lead-out pole seat, a voltage-equalizing cover, a pressure cone, a copper shielding layer, a rubber insulator, a tail pipe, an outer shielding layer, an insulating layer, and a battery cell. The outer diameter of the base is fitted with a mounting base, and the inner diameter of the upper end of the mounting base based on the center of the mounting base is provided with a rubber insulator. The outer surface of the pressure cone is a copper shielding layer, and a voltage-equalizing cover is installed at the cocentric position of the top of the pressure cone. The top position of the voltage-equalizing cover is set with a lead-out pole seat, and the tail pipe is threadedly installed at the lower end of the base. The center of the tail pipe is sequentially installed with a battery cell, a battery cell insulating layer and an outer shielding layer from the inside to the outside. This is a new type of stress cone. The device design is suitable for cable installation operations. The copper shielding layer on the outer layer of the pressure cone can well 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. The setting of the rubber insulator ensures the insulation performance between the connectors, and the multi-layer setting of the outer shielding layer and the insulating layer reduces the electric field strength.

[0004] The above technical solution does not have a good fixing structure when in use, and the installation is cumbersome and inconvenient to use, resulting in low construction efficiency. In addition, when in use, the length of the structure is limited, and the cable needs to be cut after precise measurement, which wastes the cable.

[0005] In view of the above problems, the utility model provides a stress cone structure. Utility Model Content

The utility model is provided with a tightening and fixing device, which is convenient for construction personnel to install the device, and the length of the device can be adjusted, without excessive cutting of the cable, saving the cable, thereby solving the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stress cone structure, comprising a fixing ring, the inner wall of the fixing ring is threadedly connected to a fixing rod, one side of the fixing rod is fixedly connected to an inner shielding layer, the outer surface of the inner shielding layer is fixedly connected to an insulating layer, the outer surface of the insulating layer is fixedly connected to an outer shielding layer, the outer surface of the outer shielding layer is fixedly connected to an outer shell, and one side of the outer shell is fixedly connected to an extended threaded ring.

[0008] Furthermore, the cable fixing rod is made of stainless steel, and under the action of the fixing ring, it will gradually tighten and clamp the cable, thus achieving the effect of a fixing device.

[0009] Furthermore, the inner shielding layer is made of copper, which plays a role in shielding the electric field and achieves the effect of shielding the electromagnetic field.

[0010] Furthermore, the insulating layer is made of rubber, so that the conductor in the cable is insulated from the surrounding environment or adjacent conductors, thereby achieving an insulating effect.

[0011] Furthermore, the protective outer shell is made of black polyethylene, which plays a protective role and achieves the effect of protecting the inside of the cable.

[0012] Furthermore, the extending threaded ring is made of stainless steel and serves to connect with another section of the device, thereby achieving the effect of extending the device.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model provides a stress cone structure,

[0015] (1) By setting the fixing ring and the fixing rod, a fixing effect is achieved during use. After the cable is inserted into the fixing rod, the fixing rod is gradually retracted by the fixing ring, thereby achieving the effect of fixing the device. The use is simple and convenient, and the construction efficiency is improved.

[0016] (2) Through the setting of the outer shell and the threaded ring, an extension effect is achieved during use.
