Rectangular Connectors - Housings

Rectangular connectors are types of electrical devices used to connect and secure two or more electrical conductors in an electrical system, such as circuit boards, power supplies, test equipment and other electronic devices. They are designed to provide safe, efficient connections for a variety of applications. The connectors provide an ideal solution for a wide range of electronic components, from circuit boards and power supplies to test equipment, motor controllers and other electronic components.

0003091163 Application Field and Working Principle

Rectangular connectors are ideal for use in a variety of applications, such as automotive, industrial, and consumer electronics. The efficiency and safety of a connector largely depend on the quality of the components used in its design and construction. The selection of components used to construct a connector, along with the physical shape of it, will determine the flexibility, durability, performance, and dependability of the connector. Because of this, the quality of the components used in the construction of a connector is a highly important factor.

The most common types of rectangular connectors include D-subminiature (D-sub), rectangular board-to-board, rectangular wire-to-wire, RJ45 and spade lugs. Commonly used in display, computer, communication, consumer electronics, automotive, and industrial applications, these connectors provide a variety of features to meet varied application needs. The expansive range of equipment available allows for reliable connections and transporting of electrical signals.

The basic working principle of a rectangular connector is to provide a secure connection between two or more electrical wires, allowing electricity to flow between them. To ensure this process, a connector is precisely designed and constructed to fit snugly into the printed circuit board, contact pins, or other electrical components. These components also must be designed with proper insulation and power ratings to ensure the safety and reliability of the connection. Additionally, connectors are also equipped with built-in strain relief feature to prevent the wire from becoming loose over time due to vibration or other disturbances.

The size and shape of the rectangular connector can vary based on the application and needs. To support a larger number of electrical components, a larger rectangular connector may be used. In some cases, multiple connectors can be used in tandem to support additional components. Connectors come in various materials, such as polyamide, nylon, metal, and plastic. Each material offers distinct benefits in terms of strength, corrosion resistance, temperature range, and cost.

Electrical conductivity in a connector typically occurs by contact between two pins, which each have specific ratings of electrical current they can carry and different amounts of resistance to current. The pins of a connector can be metal, plastic, or a combination of both materials. Pins are designed to make contact with the wire they are securing, creating an electrical circuit. The contact area between the pins and the wire is often coated with a plated metal, such as gold or silver, to ensure a reliable connection.

Rectangular connectors are considered to be the preferred choice for a variety of applications, as they offer superior electrical performance, high quality construction, and excellent protection against vibrations and other hazards. Additionally, they provide protection against EMI/RFI interference, moisture, and dust. The versatility of rectangular connectors, along with their affordability and easy installation, make them the ideal solution for a wide range of common applications.
