What are crimp terminals?
Crimp terminals are necessary components for connecting electrical wires to electrical devices and transmitting electricity and signals.
Developed around 1925, before crimp terminals became widespread, soldering was the mainstream method of connection.
Benefits of using crimp terminals
In addition to using crimp terminals, other methods of connecting electrical wires to electrical devices include soldering or securing the connections with insulating tape.
However, connecting by soldering requires skill and there is a risk of burns.
Moreover, using insulating tape to secure wires can lead to short circuits and makes it difficult to organize wires of varying thicknesses, types, and standards neatly.With crimp terminals, you don’t have to worry about getting burned or connecting different electrical wires!
Insulated crimp terminals offered by our company
We offer two types of insulated crimp terminals: round/R-type and insulated crimp terminals (open tip/Y-type).
Insulated crimp terminal (round type/R type)
Insulated crimp terminal (open end/Y type)
When using it, it doesn’t actually matter which crimp terminal you choose.
Here we will introduce some selection points to help you choose the right crimp terminals more smoothly.
Selection points
- 1. “Round type/R-type” and “Open end type/Y-type”
- The advantage of the “round/R type” is its safety.
- On the other hand, the advantage of the “leading edge type/Y type” is that it is easy to work with.
- Therefore, the key point in making a selection is whether to prioritize safety or ease of use.
| Advantages | ×Disadvantages | |
|---|---|---|
| Round/R type | It is a little cheaper than the tip-opening type, which is safer . Even if the screw loosens a little, it will still be attached. *Loosening to the point where the terminal floats may cause a spark. | Poor workability (e.g., screws must be completely removed before installation) |
| Open end type/Y type | Easy to use (e.g. no need to remove screws, can be installed immediately) | Less safe. Compared to the round type, it is a little more expensive. Ex. If the screw becomes loose, it will come off. Ex. There is a risk of direct contact with electricity. |
- 2. Advantages and disadvantages of “isolation”
- The advantage of “insulation” is that it can be installed anywhere.
- Another advantage is that there is no need to insulate after installation, which saves you time and effort.
- However, the disadvantage is that it is a little more expensive than a “bare” crimp terminal.
- If you are inexperienced, it may be preferable to choose the “insulated” type.
| Advantages | ×Disadvantages | |
|---|---|---|
| insulation | Can be installed anywhere. No need to worry about insulation . Can be installed bare or with a lid. | It is more expensive than naked |
It is often said that the choice of crimp terminals ultimately comes down to personal preference.
Technicians with more experience tend to use the system more intuitively and effortlessly.
However, when you are still inexperienced, you may not know what criteria to use.
