What is a through hole connector

A through-hole connector is an electronic component used to create an electrical connection and mechanical fastening on a printed circuit board (PCB).Through hole connectors ensure efficient and stable transmission of current and signals through their reliable soldering connections. As key components on circuit boards, through hole connectors are not only responsible for transmitting power and signals, but also provide solid mechanical support for the stable operation of equipment.

How Through Hole Connectors Work

The working principle of the through-hole connector is based on its physical structure and electrical connection method. By inserting pins on the printed circuit board (PCB), manual soldering or wave soldering process, the end of the pin is soldered to the pad on the PCB to form a firm electrical and mechanical connection, realizing the transmission of electrical signals and mechanical fixation.

 

Application scenarios of through-hole connectors

1.Energy Storage:Through-hole connectors can be used in solar photovoltaic (PV) systems, wind power generation systems, electric vehicle (EV) charging systems, battery energy storage systems, smart microgrids and other energy storage systems.

2.Shipbuilding:Through-hole connectors can be used in modular design, battery pack connection, power system foundation and other applications in the marine field.

3.Medical Devices:Through-hole connectors are used to connect various sensors, monitors, treatment equipment, and various accessories in medical equipment to achieve power, data, and signal transmission between devices.

 

Key Factors in Selecting Through-Hole Connectors

Electrical requirements

1.Current and voltage: Determine the current and voltage that the connector needs to carry, and choose a connector with a rating higher than the actual needs.

2.Signal integrity: When transmitting high-frequency signals, choose connectors with impedance matching and low loss.

 

Mechanical requirements

1.Number of pins and pitch:Select the appropriate pin number and spacing based on circuit requirements.

2.Size and shape:Make sure the size and shape of the connector fits the PCB layout and enclosure design.

 

Environmental requirements

1.Temperature range: Ensure that the connector can work normally within the temperature range of the application environment.

2.Protection level: In harsh environments, choose connectors with appropriate protection levels (such as IP rating).

3.Corrosion resistance: In corrosive environments, choose connectors made of corrosion-resistant materials.
