XH terminal block is a commonly used electronic connector, belonging to the category of micro connectors. It was developed by JST (Japan Solderless Terminal) and is sometimes referred to as the JST XH connector. XH terminal blocks are mainly used for connecting circuit boards, especially popular in small electronic products and model making.

characteristic:

Compact and compact: The XH terminal holder is designed to be very compact, suitable for applications with limited space.

Standardized spacing: The pin spacing of the XH terminal block is 2.5mm (approximately 0.098 inches), which is a relatively small spacing that helps reduce the space occupied by the connector.

Easy to use: The XH terminal block is designed for quick and easy wire connections, usually without the need for additional tools.

Durability: The XH terminal block is made of high-quality materials and can withstand a certain number of insertion and extraction times, making it suitable for repeated use.

Structural composition:

The basic structure of XH terminal block includes:

Pin: Usually made of copper alloy, it has good conductivity and elasticity, and the surface may be coated with gold, tin, or other metals to improve performance.

Plastic base: The part that supports the pins, usually made of heat-resistant plastic, used for insulation and fixing the pins.

Fixation method: The XH terminal block can be fixed to the circuit board through Through Hole or Surface Mount (SMT). The plug-in terminal block is fixed in the holes of the circuit board by welding, while the surface mount terminal block is directly soldered to the surface of the circuit board.

usage method:

Choose the appropriate XH terminal block: Select the appropriate number and type of XH terminal blocks according to the circuit design requirements.

Installation on the circuit board: Insert the XH terminal socket into the corresponding hole on the circuit board (for direct insertion), or place it in the designated position on the circuit board (for surface mount).

Welding: Use a soldering iron to solder the pins of the terminal block onto the circuit board, ensuring that the soldering points are secure and free of short circuits.

Connecting wires: Peel off a small section of the insulation layer of the wire and insert it into the pin hole of the XH terminal block. Usually, slight pressure is required to ensure good contact.

Application:

XH terminal blocks are widely used in various electronic devices and systems, including:

Microcontroller and sensor module

Battery charger and power management system

Electronic equipment for model aircraft and drones

LED lighting system and display screen

Consumer electronics and small appliances

XH terminal blocks have become one of the commonly used connection solutions for electronic engineers in designing and manufacturing compact electronic devices due to their compact, easy-to-use, and reliable performance. With the trend of miniaturization and lightweighting of electronic products, XH terminal blocks are increasingly widely used in modern electronic manufacturing industry.
