Introduction

18875-4 rectangular connectors, also known as headers, receptacles, female sockets, are a type of electrical connector commonly used in the computer, automotive and industrial electronics industries. The connectors are commonly used for the purpose of connecting and placing electrical components into circuit boards. These connectors can come in different sizes and shapes, as well as in different number of pins.

Construction

18875-4 rectangular connectors are composed of an insulated housing with plated contacts. The insulation is composed of a polyamide material that is rated to a temperature of 200 degrees Celsius. The contacts on these connectors are usually made of brass, and are typically plated with either a gold or a tin-lead alloy. The contacts are then held in place by a series of springs. This ensures a secure connection between two components during operation.

Application Field and Working Principle

18875-4 rectangular connectors are commonly used in a variety of applications, such as automotive, industrial, and computer-related electronics. The connectors are used to interconnect different circuit components between boards or within a board. This is achieved through the use of pins, which serve as the contact point between the two components. The pins make contact with the contact material on the circuit board, and the contact established allows the electrical current to flow between the two components.The connector also includes a locking mechanism, which is used to ensure an effective connection between two components. This usually involves a slot that mates with a tab on the housing. When inserted into the housing, the tab engages the slot, causing the two components to lock in place. This prevents the connection from becoming loose or disconnected during high levels of vibration or electrical current.

Conclusion

The 18875-4 rectangular connector is an important part of many electronic systems, as it helps to ensure a secure connection between two components. The connectors are composed of insulated housing material and gold- or tin-plated contact pins, which create an effective connection between two components. The connectors are used in a wide variety of industries, including automotive, industrial, and computer. Additionally, the connectors are also used to interconnect components between boards or within a circuit board. The locking mechanism of the connectors also ensures that the connection remains secure, even during times of heavy vibration or high levels of electrical current.
