Crimp pin connectors are solderless electrical connections used to terminate stranded wire by inserting the stripped end of the wire into part of the terminal. The crimped end has a single pin and can be connected with other pins or inserted separately into an appropriate receptacle.
Different types of crimp pin connectors
The most common types of crimp pin connectors are:
Barrel connectors
Barrel connectors are a type of crimp pin connectors that are built with a cylindrical metal opening through which the wire is inserted before crimping.
Open barrel connectors
Open barrel connectors, characterised by their U or V shape, allow the wire to be spread or cradled within the connector. This design facilitates a more secure and reliable connection as it ensures that the wire is properly positioned before crimping.
Open-barrel crimp pin connectors
Open-barrel crimp pin connectors are preferred for automation as there is no need to funnel stranded wire into the narrow opening of a barrel terminal.
Different contact plating options
Choosing the right contact plating for connectors is essential for ensuring reliable performance and longevity in various applications.
Tin crimp pin connector
A tin crimp pin connector features a layer of tin plating over its contact surface. Tin is commonly used for its excellent solderability and corrosion resistance. These connectors are ideal for applications requiring good electrical conductivity and moderate environmental protection.
Brass crimp pin connector
A brass crimp pin connector consists of a base material of brass, which is then plated, often with materials like nickel or gold. Brass connectors offer high strength and excellent conductivity. They are suitable for applications demanding robust mechanical performance.
Applications of crimp pin connectors
Crimp pin connectors are used in various industries due to their durability, reliability, and efficiency. Here’s how they are applied:
- Industrial applications: In industrial settings, crimp pin connectors are used in machinery, control systems, and heavy equipment. Their durability allows them to withstand harsh factory conditions like high temperatures, vibrations, and chemical exposure.
- Military applications: Crimp pin connectors are essential in military equipment, including communication devices, radar systems, and weapons. They endure extreme conditions such as high-impact shocks, wide temperature ranges, and moisture, ensuring military systems remain operational in critical situations.
- Automotive applications: In the automotive sector, crimp pin connectors are used in vehicle electrical systems, including wiring harnesses, lighting, infotainment, and engine control units. They simplify assembly by eliminating the need for soldering and provide reliable connections that withstand vibrations and thermal cycling.
- Large-scale production applications: In large-scale manufacturing, crimp pin connectors are used in producing consumer electronics, home appliances, and computing devices. Their quick and repeatable installation process, often automated, ensures consistent quality and efficiency.
As with any other product, crimp pin connectors are safe for use but they need to be handled with care. Read our complete guide to industrial electrical safety to protect yourself or your employees.
How to choose the right terminal crimp pin connectors for your needs
When selecting terminal crimp pin connectors, consider factors such as the electrical requirements, environmental conditions, and mechanical stresses of your application. Furthermore, ensure compatibility with the wire gauge and material, as well as the connector's current rating and insulation type. Look for connectors that offer durability, corrosion resistance, and ease of installation, particularly if they will be exposed to harsh conditions.
