Description

Technical Field

[0001] The utility model relates to the technical field of line connection, in particular to a line connection structure for electric power engineering. Background Art

[0002] Electric energy, as a product, is different from other types of products in that it cannot be stored. Therefore, the electric energy produced and transmitted by the power system composed of power plants, transmission lines, substations and distribution networks at all times must be consistent with the user's electricity consumption. This makes electricity production closely related to the national economy and people's lives. Therefore, in the planning, design, construction and operation of power projects, attention must be paid to ensuring the high reliability of power supply.

[0003] In the prior art, line connection is indispensable in the process of power engineering construction. Conventional line connections mostly use copper sleeves or wrap the butted conductors together, resulting in loose line connections. During the installation, dragging and pulling process, the line connections are prone to loosening or separation, resulting in poor connection between lines. At the same time, after the lines are connected, the waterproof sealing effect is poor, which easily causes external rainwater and dust to enter, resulting in short circuits at the circuit connections and other problems, making it unsafe to use.

The inner wall of the elastic rubber sleeve corresponding to the annular groove is provided with a convex ring, and the convex ring is buckled in the annular groove.

[0008] Furthermore, the cross section of the sealing rubber sleeve is a conical structure.
