What is a round hole pin and female connector?porcelain thimbles factory

　　This kind of connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters. 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. Usually used with female headers to form a board-to-board connection; or used 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 specifications required by different products are not the same, there are also many types of pin headers, which are classified according to the standard of the pin header connector of the electronics industry:

　　According to the spacing, 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 installation method: 180° is represented by S, 90° is represented by W, and SMT is represented by T.

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

　　Number of needles: 02to80

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

　　Dimensions: overall dimensions, length, width, thickness, and row spacing.

　　Pitch: There are 0.8, 1.0, 1.27, 2.0, 2.54 pitches.

　　Material: refers to the material and surface treatment of the contact piece, 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 nickel-plated and then gold-plated 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, usually gold plating, needle length, etc. are the most affected.
