Electrical dominoes are a commonly used product in daily life and production. So do you know their structure, classification, and how to choose electric Dominoes? Through the article below, Amazen will give you the necessary information so you can have a better overview of this product!
1. What is an electrical wiring bridge?
The English name of the electrical wiring bridge is Terminal block, also known as electrical domino. This is a device used to connect control devices or dynamic devices. This product line has the role of helping to connect electrical circuits in electrical systems or in electrical panel cabinets.
Electrical wiring bridge (Domino)2. Classification of electrical wiring bridges
There are many types of electrical wiring bridges (electrical Dominoes) such as: jack terminals, block terminals, block terminals, assembled terminals, separate eye terminals, ground terminals,... Each type of electrical terminals will have a specific use to meet each need and environment.
- Assembly bridge: It is a type of head structure with a cover, mounted on the rail.
- Detachable eye socket: It is a type of head structure installed on the rail (Din rail). This type has the advantage of being able to change the quantity at will, easy to disassemble and convenient.
- Ground connection: It is a type of structure with 2 grounding pins, ensuring safety for users during use. Grounding bridges are often painted yellow-green to easily distinguish them from other bridges.
- Connector jack: Suitable for all applications in industries, especially in machine manufacturing. This industry requires short assembly and construction times, high voltage and medium voltage electrical panels, etc.
- Block terminal: A specialized type of wire terminal used to install electrical cabinets, connect to push buttons, motors, etc. or as an intermediate terminal to connect electrical circuits. The connector includes types from 4P to 24P, forming a block of current up to 500A.
1-level electrical wiring bridge: 1-level electrical wiring bridge is the most basic type of electrical connector, easiest to install and has the function of connecting 2 electrical wire ends together. This type of bridge is also known by the shorter name of single electric bridge or single domino. With a simple one-stage structure, the single-wire bridge will only have 1 conductive bar and 2 wire clamps (contacts).
2-level electrical wiring bridge: Similar to the single-level electrical wiring bridge, the 2-level electrical wiring bridge differs only in that there is one more connection layer and is arranged above the first wiring layer below. The main purpose of layering this bridge is simply to save space.
3-layer electrical wiring bridge: 3-level electrical wiring bridge is made with more than one wiring layer located at the top, helping users save space and still connect more pairs of wires.

4. Advantages of electrical wiring bridges
Electrical dominoes are considered the optimal installation solution for today's electrical circuit systems because of the practical benefits it brings:
Easy to use and disassemble
The design of the electrical wiring bridge is quite simple, without too many complicated details. Furthermore, this device also has light weight and compact size. This will not save too much time or effort from the user during installation or use.
Have many choices
Currently the market is offering many different types of tournaments. Users can choose the corresponding device depending on their needs and purposes. In addition, the variety of designs and features will make it easier for users to choose.
Reasonable price
Although they play an important role in electrical circuits with high quality of use, most of the prices of electrical wiring bridges on the market are extremely competitive. Users will not have to worry much about equipment investment costs when they need to design industrial electrical cabinets or electrical systems. Furthermore, the cost savings that the device brings is not small, so all users can feel secure when choosing.
High efficiency of use
Electric Domino is a device with very good anti-corrosion and anti-oxidation properties. This is because manufacturers often cover the surface of the device's sections with an anti-corrosion layer. Therefore, electrical equipment is increasingly chosen for application in today's industrial environment.
Long lifespan
This product is manufactured from high-quality raw materials so it has very high fire and explosion resistance. In particular, electric dominoes can also adapt well to many different environmental conditions, especially environments with temperatures much lower or higher than normal. Therefore, the device will be highly durable during use. This helps users save on equipment replacement or maintenance costs.
5. Application of electrical wiring bridge
The main task of the electrical wiring bridge is to connect the ends of the electrical wires together. Electrical wire bridges are not only widely used in industry and electrical engineering but also in some civil electrical applications serving daily life.
In industry, electrical wiring bridges appear mostly in electrical cabinets and circuits of:
- Automobile assembly factory lines and systems
- Manufacturing and assembling electronic components
- Food Processing
- Mechanical manufacturing of machines, equipment, and tools
- Build
- Weaving yarn and garments
- Paper production...
6. Selection criteria when purchasing electrical wiring bridges
The following are the parameters and characteristics of electrical current, environment and type that Amazen conveys to you to keep in mind during the selection process when buying an electrical wiring bridge.
Electricquota
- Current rating is the top factor you need to consider. If the current is too large, it will cause the electrical connection to overheat and lead to premature failure or, even more dangerous, a fire or explosion.
- Engineers at Amazen, when choosing an electrical connection, set a standard that the electrical connection must be able to withstand the expected current use plus 50%.
- For example, the expected current used is 2A, then we should choose an electric domino that can withstand current up to 3A.
Electrical system voltage
- Voltage is the second most important factor that needs to be taken into account when buying an electrical wiring bridge. If the wrong voltage is chosen, the dielectric will be broken down. If the voltage is too high, it will lead to power leakage between adjacent blocks. That's why some people think there is no need to check if the voltage of the system used is less than 100V. However, to be careful, we encourage customers to check before deciding to buy an electrical connector.
Usage environment and durability
- Environment and mechanical durability are very important factors when choosing electrical wiring bridges. Some connectors are mechanically strong, but when used in unfavorable environments, they will be detrimental to the metal contacts. So when buying a tournament, we need to pay attention to both of these factors at the same time.
Number of phases/eyes of the player
If we intend to use a type of wire terminal where the number of connections is fixed, we need to accurately determine the appropriate number of connections. Because this type of fixed bridge cannot be flexible in changing, adding or removing the number of links.
What type of wire do you use for connection?
Electric wires or other connecting devices will also have different advantages and disadvantages. If you choose an electrical connector for an electric cable, you need to clearly understand the size of the cable to know whether it corresponds to the connector or not? Is that type of wire dual-core, multi-core or single-core? Because single-core wires work better in push-on connectors, multi-core wires are suitable for screw connectors.
