Bare crimp terminal "Y type / R type"
What is a crimp terminal?
Crimp terminals are essential components for connecting cables and electrical equipment and exchanging power and signals.
It was developed around 1925, before crimp terminals became popular and soldering was mainstream.
Advantages of Using Crimp Terminals
Cables and electrical equipment can also be connected by soldering, insulation tape, or direct wrapping, but crimp terminals provide a cleaner and more reliable connection.
However, soldering requires technical skill and can cause burn risks.
When secured with insulating tape, there is a risk of short circuits and it is difficult to assemble different cable thicknesses/types/standards beautifully.
Point crimp terminals eliminate the need to worry about burns or connections between different cables.
Bare crimp terminal
Two types: bare crimp terminal (round/R-type) and bare crimp terminal (open front/Y-type).
-
Bare crimp terminals (pill type/Ｒ type)
-
Bare crimp terminals (first open type/Y type)
In fact, there is no problem in choosing any crimp terminal.
The following section explains the advantages and disadvantages of non-insulated crimp terminals and key points to consider when selecting them.
Terminal introduction
- 1. "Round type/R type" and "First opening type/Y type"
- The advantage of "round type/R type" is that it is safe.
- The open-end/Y-type design is easy to install and process.
- Therefore, the focus of selection is to prioritize safety or processability.
| 〇Advantages | ×Disadvantages | |
|---|---|---|
| Pill type/R type | Good safety A bit cheaper than Model Y For example, even if a screw is slightly loose, it will still hold *Looseness enough to lift the terminal may cause sparks. |
Poor operability Ex. The screws must be completely removed and installed |
| Pre-opening type/Y type | good processability Ex. Can be installed immediately without removing screws. |
Poor security Price is slightly higher compared to round shape If the screw is loose, it may fall off directly Ex. Risk of direct contact with electricity |
- 2. Advantages and Disadvantages of Half-Open Type
- The advantage of "exposed" is that it reduces working time and is cheaper than semi-insulated.
- However, if it is installed in an exposed place, there is a risk of direct contact with current, so heat shrink tubing must be used for insulation after installation.
| 〇Advantages | ×Disadvantages | |
|---|---|---|
| naked | Working hours can be shortened Cheaper than semi-insulated For example, place it where there is no direct contact, such as with a lid |
Poor security Depending on the installation location, insulation may be required later. |
The choice of crimp terminals is usually based on the user's preference.
Experienced engineers often make choices based on past experience.
