Rectangular Connectors - Headers, Receptacles, Female Sockets, consist of electronic components or contact devices used to mechanically support, mount, and electrically connect wires, cables, and other electrical and electronic components in electrical boxes. One of the most commonly used rectangular connectors within these applications is the 87983-4 connector. This topic will discuss the application fields of 87983-4 rectangular connectors and the basic working principle behind it.

Application Fields

The 87983-4 connectors are mainly used in automotive and industrial control applications. Automotive applications for the 87983-4 connectors include a variety of HVAC and lighting control systems. HVAC systems utilize 87983-4 connectors for connecting bus bars, wire harnesses, and terminals of cooling fans, blowers, and sensors. Additionally, 87983-4 connectors are used to join and route power and signal wiring in automotive lighting control systems. Specifically, the use of 87983-4 connectors enables the mixing and matching of different types of lighting, including daytime running lights and parking lights.

The 87983-4 rectangular connectors are also suitable for various industrial control applications. Typically, these connectors are used in the connection or transmission of power and control signals in the panels of industrial appliances. For example, these rectangular connectors can be used to supply power, as well as to transmit signal and logic signals between various sensors and other functional components for controlling the operation of an automated machine.

Working Principle

The 87983-4 connector is a rectangular connector that is composed of a male and female component. The male component features two linear rows of pins, which are surrounded by a plastic housing, while the female component consists of two rows of cavities. Each of these cavities has two contacts, namely, the positive and the negative contact which is firmly held in place by retaining clips. When the two components are connected together, the male pins press tightly against the contact in the female cavity, thus, forming a firm, electrical connection. Additionally, the housing of the male component also helps to secure the two components together. To further ensure a secure connection, a lock washer or nut can be used to lock the two components together so that they do not easily come apart.

In terms of electrical performance, the 87983-4 connector has a contact temperature range between -25°C and 85°C and an insulation resistance AC voltage of 500V. The contact resistance of the 87983-4 connector is also fairly low, typically ranging from 0.04 to 0.2 Ω/contact. This ensure that the connector has a stable electrical connection. The 87983-4 connector also features low voltage drop, due to its large cross-sectional area of contact.

The 87983-4 connectors are also suitable for a wide range of environmental conditions such as temperatures as low as -25°C and as high as 85°C, vibration, and shock resistance. Additionally, the 87983-4 connectors can also be sealed with neoprene O-rings or silicone specified for static protection, so as to prevent dust and water from penetrating the connector\'s interior. This ensures the connector\'s long-term reliability and performance.

In conclusion, the 87983-4 rectangular connectors are a versatile and reliable type of interconnected used in a wide range of automotive and industrial control applications. Not only can the 87983-4 connectors provide a secure and durable electrical connection, but they are also suitable for high-temperatures and a variety of environmental conditions. This makes them an ideal choice for connecting power, controls signals, and other functional components in industrial appliances.
