Semi-insulated crimp terminal "Y type / R type"
What is a semi-insulated crimp terminal?
Crimp terminals are parts that connect wires and electrical equipment.
It is widely used in household appliances including electrical engineering, measuring equipment, FA control equipment, etc.
It was developed around 1925, before crimp terminals became popular and soldering was mainstream.
Advantages of using semi-insulated crimp terminals
In addition to using crimp terminals, there are other ways to connect wires and electrical equipment, such as soldering or wrapping with electrical tape.
But welding requires technical skills and can cause burns.
When secured with insulating tape, there is a risk of short circuits and it is difficult to assemble different wire thicknesses/types/standards beautifully.
Crimp terminals eliminate the need to worry about burns or connections between different wires.
Semi-insulated crimp terminals
Our company offers two types of semi-insulated crimp terminals, R type and Y type, which are sheathed.
-
Semi-insulated crimp terminals (Y type/open first)
-
Semi-insulated crimp terminal (round type)
There is no problem in using any crimp terminal.
Here we introduce the key points of selection so that you can choose crimp terminals more smoothly.
Select points
- 1. "Round type/R type" and "First opening type/Y type"
- The advantage of "round type/R type" is that it is safe.
- The advantage of "first opening type/Y type" is that it has good processability.
- The choice of whether to focus on safety or workability should be considered based on the actual situation.
| 〇Advantages | ×Disadvantages | |
|---|---|---|
| Round/R type | good security Cheaper than Y-type products Ex. Even if the screws are a little loose, they still stay connected. ※*Looseness enough to lift the terminal may cause sparks. |
Poor processability 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 The price is slightly higher than the round type Ex. If the screw is loose, it may fall off directly. Ex. There is a risk of direct contact with electricity. |
- 2. Advantages and disadvantages of "semi-insulation"
- The advantage of "semi-insulated" is that you can choose any installation location.
- In addition, since insulation is not required after installation, it has the advantage of being labor-saving and easy.
- However, the downside is that the price is slightly higher than "bare" crimp terminals.
- If you have no experience, you may prefer to choose the "semi-insulated" type.
| 〇Advantages | ×Disadvantages | |
|---|---|---|
| Semi-insulated | Installation location is not restricted No insulation required For example: bare, add protective cover. |
Price higher than bare crimp terminals |
The choice of crimp terminals is usually based on the user's preference.
Experienced engineers often make choices based on past experience.
However, if you have no experience and don’t know where to start when choosing a judgment benchmark
