DETAILED DESCRIPTION
[0014] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.
[0015] Example
[0016] like Figure 1-Figure 4 As shown, a high-voltage connection tail attachment structure comprises a lower tail attachment structure 1, an upper tail attachment structure 2 is installed on the lower tail attachment structure 1, and the cable is clamped in the middle by the lower tail attachment structure 1 and the upper tail attachment structure 2.
[0017] Among them, the lower tail attachment structure 1 includes a base 3, a semicircular mounting hole 4 is opened in the middle of the base 3, a lower cover plate 5 is installed on one side of the mounting hole 4, a semicircular lower fixing groove 6 is provided in the middle of the lower cover plate 5, and the mounting hole 4 and the lower fixing groove 6 are structures with different diameters of the same center, which are used to provide space for cables and terminals to pass through. A sealing groove 8 is opened on the lower cover plate 5, and the sealing groove 8 is an L-shaped structure, with two being respectively located on both sides of the lower fixing groove 6. An arc-shaped sealing groove 9 is opened on one side of the mounting hole 4, and the arc-shaped sealing groove 9 corresponds to the position of one end of the sealing groove 8. The sealing groove 8 and the arc-shaped sealing groove 9 surround the lower fixing groove 6 and the mounting hole 4 for sealing. Lower threaded holes 7 are opened on both sides of the lower cover plate 5 to provide fixed connection points for the lower tail attachment structure 1 and the upper tail attachment structure 2 to be connected. Fixed through holes 18 are opened at the four corners of the base 3 for fixed installation of the high-voltage connection tail attachment structure.
[0018] The upper tail attached structure 2 includes an upper cover plate 10, an upper fixing groove 11 is provided in the middle of the upper cover plate 10, the rear end of the upper fixing groove 11 is connected to a semicircular upper fixing plate 12, the upper fixing plate 12 is connected to the upper cover plate 10, a semicircular groove 14 is opened on the upper fixing plate 12, the semicircular groove 14 has the same radius as the upper fixing groove 11 and is connected, upper threaded holes 15 are provided on both sides of the upper cover plate 10, the lower threaded holes 7 are connected to the upper threaded holes 15 by bolts, a sealing boss 16 is installed on the upper cover plate 10, and the sealing boss 16 corresponds to the structural position of the sealing groove 8, and an arc-shaped sealing boss 17 is provided on the upper fixing plate 12, and the arc-shaped sealing boss 17 is installed inside the arc-shaped sealing groove 9 for sealing.
[0019] When in use, the base 3 is installed on the high-voltage equipment, and then the cable is passed through the cable base. A flexible and compressible sealing material is wrapped on the cable for tight sealing. Then the upper cover plate 10 is pressed on the cable, and finally the lower threaded hole 7 and the upper threaded hole 15 are fastened by bolts. The sealing boss 16 in the upper cover plate 10 cooperates with the sealing groove 8 on the lower cover plate 5, and the arc-shaped sealing boss 17 cooperates with the arc-shaped sealing groove 9 to achieve a sealing effect.
