Description

Technical Field

[0001] This utility model relates to the field of zinc-clad steel production and manufacturing, and in particular to a large-diameter zinc-clad steel grounding material connector. Background Technology

[0002] Previously, zinc-clad steel grounding materials were mostly connected by welding, which was very difficult to construct due to limitations in the construction environment and the way the grounding grid was laid. If exothermic welding is used to connect zinc-clad steel grounding materials into a network, not only will the construction be difficult, but the construction cost will also increase significantly. After the steel core of zinc-clad steel is welded, it still needs to be coated with a zinc layer; otherwise, the service life of the grounding grid will be affected. Utility Model Content

[0003] To overcome the above problems, this utility model provides the following technical solution: a large-diameter zinc-clad steel grounding material connector, comprising a steel core, a zinc cladding layer, and an internal connection thread; The steel core is provided with internal connecting threads at both ends of the axial direction for threaded connection with the zinc-clad steel grounding material; the outer surface of the steel core is covered with a zinc cladding layer for tight zinc-zinc connection when threadedly connected with the zinc-clad steel grounding material. The connecting internal thread is a tapered internal thread, used to make a tight threaded connection with the zinc-clad steel grounding material with a tapered connecting thread, so that the steel is tightly connected to the steel.

[0004] Furthermore, the outer diameter of the zinc coating is hexagonal, and it can be tightened using a tool.

[0005] Furthermore, the taper of the connecting internal thread is the same as the taper of the connecting thread of the zinc-clad steel grounding material.

[0006] Furthermore, O-rings are provided at both ends of the zinc cladding layer to further seal the internal thread connection between the zinc-clad steel grounding material and the connector.

[0007] This utility model has the following beneficial effects: 1. The use of threaded connections greatly reduces construction difficulty and is unaffected by the environment; 2. The tapered threaded connection ensures both a secure connection and a tight seal. 3. The structure is made of zinc-clad steel, which meets the bimetallic structure characteristics of zinc-clad steel grounding materials. The steel core and the zinc coating are connected to the zinc-clad steel grounding material in layers, with steel connected to steel and zinc connected to zinc, which meets the metal conductivity characteristics and extends the service life of the grounding grid.

The connecting internal thread 3 is a tapered internal thread, used to make a tight threaded connection with the zinc-clad steel grounding material with tapered connecting threads, so that the steel is tightly connected to the steel.

[0011] Furthermore, the outer diameter of the zinc cladding layer 2 is hexagonal, and it can be tightened using a tool.

[0012] Furthermore, the taper of the connecting internal thread 3 is the same as the taper of the connecting thread of the zinc-clad steel grounding material.
