What is a round hole pin - row busbar connector?

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 usually used together with the row bus to form a plate-to-plate connection. Or it can be used together with the electronic wire harness terminal to form a plate-to-wire connection; It can also be used independently for plate to plate connection.

Due to the different specifications required by different products, there are also a variety of models and specifications, which are classified according to the standards of pin laying connectors in the electronics industry:

According to the spacing 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 of needles, double row of needles, three rows of needles, etc. According to the packaging rules have SMT (horizontal paste/vertical paste), plug-in DIP (straight insert/bend insert); Divided by installation: 180° is represented by S, 90° by W, SMT 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.

Spacing: 0.8, 1.0, 1.27, 2.0, 2.54 spacing.

Material: refers to the contact material and surface treatment, insulator 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 process: The main processing process of needle arrangement is: first, the needle insertion is processed with brass (or phosphor bronze) as required.

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

It is required to insert the pin into the insulator.

Note: there are many factors affecting the price, usually the most influential ones are gold plating, needle length, etc.

Example of needle arrangement parameters

Features of round hole row: single row and double row, straight needle and bent needle, needle spacing is 2.54mm and 3.96mm, a variety of needle length.
