XH2.54 2P-12P 26AWG Wire Harness
Description
XH2.54 terminal wire is an electronic connection system. The following is a detailed introduction to it:
I. Definition and naming
XH2.54 terminal wire refers to a 2.5/2.54MM pin header connector, also known as a terminal wire.
XH2.54 terminal was originally a part number of JST (Japan Standard Time, Japan Solderless Terminal Manufacturing Co., Ltd.). With the increasingly widespread use of XH2.54, many factories have begun to imitate it. The manufacturer uses such a code to make it more convenient for the selector to know the matching situation with JST.
Now domestic connector manufacturers add (XH, EH, EI, VH) and the like after their own product names, mainly to facilitate the habits of customers.
II. Structure and design
XH2.54 terminal wire is mainly composed of two parts: the terminal and the rubber shell, and the XH rubber shell with a spacing of 2.54mm is used at both ends.
Wire parameters: PVC insulation material, with a maximum outer diameter of 2.0mm.
Number of pins: There can be different numbers of pins to meet different connection needs, ranging from several pins to dozens of pins (including packaging such as bent pins, straight pins, horizontal stickers, and vertical stickers).
Wire type: It can be various types of wires, such as single-strand copper wires, stranded wires, multi-strand wires, etc., depending on the application requirements.
Plug and socket: One end of the wire may be equipped with a plug for connection to other equipment or connectors; the other end may be directly connected to the XH2.54 terminal socket or pin.
III. Specification parameters
Spacing: The spacing between the socket and the pin is 2.54 millimeters (0.1 inch), which is a common standardized spacing and is suitable for various electronic connection needs.
Color coding: In multi-wire connections, different colors of wires may be used to distinguish different signals or functions. For example, red is usually used as the positive pole (+) of the power supply, black is usually used as the negative pole (-) of the power supply, blue is usually used as the signal line, and green is usually used as the ground wire.
Current carrying capacity: The current carrying capacity of the wire should be sufficient to meet the current requirements of the connected components to ensure the stability and safety of the circuit.
