What is a round hole busbar connector

Round hole busbar connector, English name: Pin Header.

This connector is widely used in electronic, electrical, instrument PCB board, its role is in the circuit is blocked or isolated between the circuit, play the function of bridge, take on the task of current or signal transmission. It is generally used with the row bus to form a plate-to-plate connection; Or it can be used with the electronic wire harness terminal to form a plate-to-wire connection; It can also be used independently for plate to plate connection.

Since the specifications required by different products are not the same, there are also various types of specifications for stitching, which are classified according to the specifications of the stitching connectors for the electronic profession:

According to the distance, it can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm. According to the row number, there are single row of needles, double row of needles, and three rows of needles. According to the packaging rules are SMT (horizontal paste/vertical paste), plug-in DIP (straight insert/bend insert); According to installation method: 180° indicated by S, 90° indicated by W, SMT indicated by T.

Number of rows: single row, double row, three row, four row, maximum four row.

Pin number: 02 to80

Stitching: straight foot, bent foot, SMT; The size of the needle.

Dimensions: External dimensions length, width, thickness, row spacing.

Distance: 0.8, 1.0, 1.27, 2.0, 2.54 distance.

Raw material: refers to contact material and surface treatment, insulator raw material.

Packing: in bubble shell, in roll bag, in bulk.

Materials: Needle insertion materials: brass or phosphor bronze; Insulator: Plastic UL94V-0.

Surface treatment: gold plating 0.8U, tin and nickel plating.

Processing technology: The main process of needle arrangement processing is: first, the needle insertion is processed with brass (or phosphor bronze) according to the requirements.

As required, nickel plating is followed by gold plating, and then mold is used to process the insulator part. Finally, a ruler is pressed on the special equipment

It is required to insert the pin into the insulator.

Fill white: the factor that affects a price is a lot of, general influence is the biggest for gold plating, needle is long wait.

Example of needle arrangement parameters

Round hole bushing features: single row and double row, straight needle and bent needle, stitching distance of 2.54mm and 3.96mm, various stitching length.
