151260-2420-TB Application Field and Working Principle

151260-2420-TB is a type of rectangular connector, namely, headers, male pins. It is widely used in industries due to its small outline, low cost, and ease of assembly. Its application fields mainly include industrial communication, computers, instrumentation, motion control, and medical equipment.

Category Description

Rectangular connectors, headers, and male pins are connector devices primarily distinguished by the size and profile of their contact structures. The common shapes of rectangular connectors are either pitch-less or a single pitch while low profile versions are starting to become more common. By ‘-TB’, we mean that this type of 151260-2420-TB has both its cut-edges and its middle peak slightly lower or with a flat shoulder, which makes it to a low-profile one.Headers are the male pin component but with two rows of pins. Male pins are the break-away pieces in strip form of headers.

Basic Construction

151260-2420-TB rectangular connectors are constructed with a variety of materials, such as PBT (polybutylene terephthalate), nylon, polypropylene, and phenol. Their choice depends on the actual elements that are affected by the connector, such as the structure, heat, dust, radiation, or other environmental factors. Unless otherwise specified, the lead pitch is 2.54mm and the plating is gold-palladium (sometimes referred to as ‘GPS’).

Components

The 151260-2420-TB rectangular connector is composed mainly of a header, a mount, an insert, a male terminal, a shell and a wire pin:

• Headers: Made of plastic or metal, it is a rectangular-shaped component with paralleled grooves on the surface.
• Mount: A component used to fix the header to the PC board. It is usually made of metal and has glass-filled plastic, chemical-conversion coatings, and phosphate coatings to prevent electrical conduction.
• Insert: Commonly made of plastic or polyethylene, an insert is used to keep the terminals separated and prevents contact between adjacent pins on the wrong side.
• Male Terminal: Also known as pin terminal, it is used to complete the electrical connection between the circuit board and the wire pin. It is usually made of brass and plated with gold or silver.
• Shell: Comes in various shapes, sizes and materials, it is used to provide efficient and secure electrical contact between the circuit board and the header.
• Wire Pins: Made of conductive material such as copper, it can be inserted into different terminal styles in order to provide a reliable, continuous connection.

Working Principle

The working principle of 151260-2420-TB connector is fairly straightforward. The header is mounted onto the PC board which sockets the wires connected to the terminals. The shell is then put in place and held securely so that it maintains a electrical connection between the board and the terminals. The insert is pushed into place to keep the terminals separated. Finally, the wire pins are inserted, which complete the electrical connection.
