Rectangular connectors, sometimes referred to as headers, male pins or male breadboards, are small pieces of hardware that are commonly used to make a secure electrical or electronic connection between two components in a circuit or device. The most common use of these connectors is in the assembly and testing of electronic products.

Application Field

The primary applications for rectangular connectors are in the automotive, aerospace, medical and consumer electronics industries. They are also used in the military, telecommunications, data processing and audio/visual industries. It is not uncommon to find these connectors in other industries as well, as they are becoming increasingly common and versatile.

Working Principle

Rectangular connectors are typically composed of multiple pins that are arranged in one or more rows. In order for the connection to be formed, the connectors must be plugged into a mating part, which is typically a mating receptacle. When the connectors are plugged in, they create a secure connection that will not be disrupted by environmental factors, such as moisture, dust, humidity or vibration. In addition, they are designed to be very stable and resist mechanical stress such as shock, vibration or other forces.

To ensure a secure connection, every pin on the connector surfaces must make contact with an opposing pin on the mating receptacle. To achieve this, the connectors are designed to use a mechanical locking mechanism, such as a snap-in or screw-in mechanism. This locking mechanism helps ensure that the connection will not be disturbed during the assembly process, as well as throughout the life of the product.

Rectangular connectors are very advantageous over traditional round connectors because they provide a more reliable connection and are easier to assemble. Additionally, they are more compact and can often provide additional space savings, as they can be assembled closer together. This can result in a smaller end-product that is less expensive to manufacture.
