Power connector: a critical connection for reliable power supply
Power connectors are connecting parts that stably supply the power necessary for electronic devices and industrial equipment. These connectors are designed to suit a variety of environments and applications, ensuring a stable and safe power supply in equipment used in domestic to commercial and even harsh environments.
Basic role of power connector
Power connectors are designed for power supply and distribution and have the following characteristics:
- Stable power supply: High quality power connector minimizes voltage fluctuations and noise when energized, providing stable power supply.
- Ensuring safety: In order to prevent fires and malfunctions due to short circuits and overcurrent, materials with excellent insulation and durability are used, and the design is such that no contact parts are exposed.
- Environmental resistance: Power connectors for industrial and outdoor equipment are equipped with waterproof and dustproof functions and maintain reliability even in harsh environments.
Main types of power connectors
There are different types of power connectors depending on the application and power requirements. Representative ones are listed below.
- Ac power connector: A connector widely used in household appliances and computers, and is a type that connects to an AC adapter or wall outlet. IEC320 connectors have become popular as an international standard.
- Dc power connector: A direct current (DC) connector often found in electronic devices and battery-powered devices, which connects in the form of a plug and jack. This type is often used to power tools and laptop computers.
- Wire connector: A power connector used in industrial machinery to directly connect equipment and power supply units. A thick cable is connected to handle large currents.
- Special purpose power connector: There are connectors with waterproof and dustproof performance, as well as connectors with specifications that can withstand harsh temperatures and vibrations, and are mainly used in military equipment and medical equipment.
Points to consider when selecting a power connector
The following factors are important when choosing a power connector:
- Current capacity and voltage:You must select a connector that supports the appropriate current capacity and voltage according to the power requirements of the equipment in use. Exceeding the capacity may cause heat generation and damage.
- Insulation and safety standards: Products that comply with safety standards such as UL and IEC are recommended for power connectors. There is a risk of electrical short circuits due to insufficient insulation.
- Environmental conditions: When used outdoors or in hot and humid environments, waterproof and dustproof functions are required. Environmental resistance is guaranteed if the product complies with IP standards.
Application fields of power connectors
Power connectors are used in a wide range of applications, from homes to industrial equipment and medical equipment.
- Home appliances: Connectors that use AC adapters or DC plugs are the mainstream, and are equipped with overcurrent protection and reverse connection prevention functions to increase safety during use.
- Industrial equipment:Large equipment, robots, etc. require power connectors that can handle high currents, and use high-efficiency designs to minimize power loss.
- Medical equipment: Medical equipment, where reliability is of paramount importance, requires a high degree of insulation and durability, so specialized medical power connectors are used.

What is a single contact (signal)?
Signal contacts, defined for "low" currents of milliamperes up to 3 amps
What is HF contact?
HF contactor in its full name High Frequency contactor is a coaxial contactor that contains a central contact that conducts the signal (signal) isolated and above it a shell of shielding (Braid) K) for EMI/RFI protection.
What is the HP touch?
Contact HP or in its full name High Power, is intended for transferring currents of 3 amperes and up to 20 amperes, the interval between one HP contact and another will be 4 mm.
What is EMI?
Electromagnetic Interference
What is RFI?
Radio Frequency Interference
What is EMI/RFI protection?
While a current is passing through the contact or the cable, a magnetic field is created, the magnetic field that is created can interfere with the electrical data that you want to transmit, and in order to prevent this interference, the cable is wrapped in a shield, with the central conductor electrically isolated from the shield.
What is COAX contact?
A coax contact is intended in communications for transmitting signals at high frequencies, it contains a central contact that conducts the signal (signal) isolated and above it a shell of shielding (Braid) to prevent EMI/RFI interference. EMI - Electromagnetic Interference
RFI - Radio Frequency Interference
How do you choose a connector according to frequency (HZ) and impedance (Impedance-Ω)?
Nicomatic offers connectors for transmitting high frequencies from 1.5GHz to 11GHz depending on the cable. For the purpose of the characterization, it is necessary to define whether the frequency to be transmitted is up to 6GHz or beyond in order to choose the appropriate cable, in case you are not sure about the frequency, it is recommended to choose the appropriate cable for a higher frequency.
When to choose a plastic connector and when to choose a metal connector?
The choice of the connector material depends on the application, plastic connectors must be used for connectors inside the box and connectors that interface outside the box and need better protection from the electrically noisy environment, we will use metal connectors, in more extreme environments, we can add an additional layer of protection to the connector called BackShell (back accessory).
What is the advantage of SMT contacts (Surface Mount Technology) compared to intrusive contacts on the PCB?
In penetrating contacts (Thru-Hole), the connector is prevented from placing components on the other side of the PCB board, while in surface mounting the bottom side of the PCB is intended for independent editing and placing additional components.
Golden advice for designing connectors on a PCB board
Depending on the required task and especially the required mechanical size, it is advisable to use connectors that have a small pitch between the contacts, thus making it possible to design a compact and lightweight package, something that is very much required in optical systems and UAVs (unmanned aerial vehicles).
