French Dubuis grounding expansion plug pin and rail plug pin

The difference between the two plug screws is as follows:

The grounding plug pin is used for equipment grounding on vehicles.

Rail plugs are used for track return grounding and signal transmission.


1. Dubis grounding plug pin

Earth Bond Hardware

Earth bond for steel and stainless plates

The grounding plug pin is suitable for stainless steel plate

Earth bond for aluminium plates

The grounding plug pin is suitable for aluminum plate

Plug grounding system is a revolutionary method to establish an electrical safety connection between the structure and the equipment to ensure that there is no short circuit when the high-intensity current passes through.

Grounding plugs for iron and stainless steel plates:

Tinned copper bushing

316L stainless steel bolt

Grounding plug pin for aluminum plate:

Nickel plated aluminum bushing

316L stainless steel bolt

Grounding nut:

Similar to plug pin, it is composed of conductive bushing and bolt with internal thread

Product features:

Suitable for carbon steel, stainless steel and aluminum * plates

It is suitable for plates with thickness of 1.5mm and above

Single side operation can complete the installation

It can be installed to blind hole

permanent low resistance electrical connections

It can be removed and replaced in case of damage

It can be used on uneven surfaces

made of corrosion resistant materials

cost effective because only a limited number of tools are required to repeat the installation work

It can be operated by one person

extensive independent testing

Recommended use of major OEMs in RMT, marine and military markets

2. Dubis rail stud

Dubis provides a solution for reliable connection, and the order of railway system network with this concept will be greatly improved. In the installation of railway plug pin, there is no impact on rail and plug pin. As long as there is no vehicle passing through, different types of drawing tools can be used to install plug pins of various specifications. The tin plated copper bushing with the best ductility and conductivity makes the electrical connection between the signal line terminal and the track optimal.
