Introduction of round hole female row pin connector.Elastic contact Vendor

　　This kind of connector is widely used in electronics, electrical appliances, and PCB circuit boards on the surface. Its function is to function as a bridge between blocked or isolated circuits in the circuit, and is responsible for current or signal transmission. Task. It is generally used in conjunction with female headers to form a board-to-board connection; or used in conjunction with electronic wiring harness terminals to form a board-to-wire connection; it can also be used independently for board-to-board connection.

　　Because the standards required by different products are not the same, there are also many types of standards for pin headers, which are classified according to the standard of electronic professional pin header connectors:

　　According to the interval, it can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm. According to the number of rows, there are single-row needles, double-row needles, three-row needles, etc.; according to the packaging method, there are SMT (horizontal stickers) /Vertical paste), plug-in DIP (straight plug/curved plug), etc.; according to the device method: 180° is marked with S, 90° is marked with W, and SMT is marked with T.

　　Number of rows: single row, double row, three rows, four rows, up to four rows.

　　Number of needles: 02to80

　　Stitches: straight feet, bent feet, SMT; the size of the needle.

　　Dimensions: shape dimension length, width, thickness, row spacing.

　　interval: 0.8, 1.0, 1.27, 2.0, 2.54 intervals.

　　Material: refers to the material and surface treatment of the touch part, and the material of the insulator.

　　Packing: blister pack, roll bag, bulk pack.

　　Material: pin material: brass or phosphor bronze; insulator material: plastic UL94V-0.

　　Surface treatment: gold plating 0.8u, tin plating, nickel plating.

　　Processing process: The main process of pin header processing is: first process the pins with brass (or phosphor bronze) as required.

　　and plating nickel and then gold as required, and then use the mold to process the insulator part, and finally press the ruler on the special equipment

　　Inch requires the pins to be inlaid on the insulator.

　　Remarks: There are many factors that affect the price. Generally, the most influential factors are gilding, needle length, etc.

　　needle row parameter example

　　Round hole pin header and female feature: single row and double row, straight needle and curved needle, the pin spacing is 2.54mm and 3.96mm, various pin lengths.
