Pin header, a connector, English name: Pin Header.
This connector is widely used in electronics, electrical appliances, instrumentation in the PCB circuit boards, its role is to be blocked in the circuit or isolated between circuits, to play the function of the bridge, to take up the task of the current or signal transmission. Usually used in conjunction with the mother of the row, constituting a board-to-board connection; or with the electronic harness terminal supporting the use of board-to-line connection; can also be used independently of the board and board connection.
Since the specifications required for different products are not the same, so there are a variety of types of pins, according to the electronics industry standard classification of pins connectors:
According to the pitch can be roughly divided into 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm five types of according to the number of rows of pins have a single row of pins, double rows of pins, three rows of pins, etc.; according to the encapsulation law there are SMD SMT (horizontal paste / vertical paste), plug-in DIP (straight / curved plug), etc.; according to the installation method: 180 ° with the S said, 90 ° with the W said, SMT with the T said.
Number of rows: single, double, triple, quadruple, up to four rows.
Number of pins: 02to80
Pins: straight, curved, SMT; pin size.
Size: external dimensions length, width, thickness, row spacing.
Pitch: 0.8, 1.0, 1.27, 2.0, 2.54 pitch.
Material: refers to the contact parts material and surface treatment, insulator material.
Packaging: blister pack, roll bag, bulk pack.
Materials: pin material: brass or phosphor bronze; insulator material: plastic UL94V-0.
Surface treatment: gold-plated 0.8u, tin-plated, nickel-plated.
Processing technology: row of pins processing process is mainly as follows: first of all, according to the requirements of brass (or phosphor bronze) processed pins,
And according to the requirements of the first nickel-plated and then gold-plated, and then use the mold to process a good insulator part, and finally in the special equipment in accordance with the size of
Inch requirements will be set on the insulator pins.
Remarks: There are many factors that affect the price, usually the most influential are gold plating, pin length, etc.
Examples of Pin Parameters
Features: single and double rows, straight and curved pins, pin spacing of 2.54mm and 3.96mm, multiple pin lengths.
Applications
●Data processing●Computers●Program control devices●Electronic measuring devices●Automation●Automation●Communication
Rectangular pins cross section of 0.8 x 1.6mm, load current 7.5A. jacks have at least two independent shrapnel, four contacts, jack structure can prevent misplugging. 254/I series square pins cross section of 0.64 x 0.64mm. 254/I series square pins with a cross-section of 0.64 x 0.64 mm are designed with obtuse corners and can be used in high-frequency technology. The contacts are gold plated for corrosion resistance, low contact resistance and high reliability.
