1053072207 application field and working principle

Rectangular Connectors - Housings are widely used in a broad range of industrial applications. They are used to make electrical bridges between two dissimilar devices or systems. These types of connectors come in a variety of shapes and sizes, with various features such as locking mechanisms, sealant, and machined contacts. It is important to select the right type of housing for the intended application.

Types of Connectors and Housings

The two main types of rectangular connectors and housings are brought together by mating contacts. One type is the double-row, two-row (also called four-position), and three-row (also called six-position) headers. These housings have two contact pins that are placed in line. The other type is the three-row, four-row (also called eight-position), and four-row (also called twelve-position) headers. These housings have three contact pins that are placed in a staggered arrangement.

The double-row and two-row headers have contacts arranged on both sides of the housing, which makes them suitable for applications where two circuits need to be connected. The three-row, four-row, and four-row connectors, on the other hand, have contacts arranged on both sides of the housing, as well as on the center of the housing, which makes them suitable for applications where three or more circuits need to be connected.

Applications

Rectangular Connectors - Housings are used in a wide variety of applications, including electronics, automation, military, aviation, marine, automotive, telecommunications, and industrial. The contact arrangements allow them to bridge the gap between different types of equipment during data transmission, power, grounding, and providing electronic connections. Additionally, they are used to connect heat sinks, PCBs, housings, and other electronic elements.

Rectangular Connectors - Housings have various features designed to ensure the connectors remain secure and reliable during operation. These features include locking lances, keying arrangements (which prevent the wrong connections from being made), and various forms of EMI and RFI shielding. Many housings also come with additional features that enhance their durability, such as insulation, corrosion resistance, protective overmolding, and durable housings for more extreme environments.

Working Principle

Rectangular Connectors - Housings are typically mated using a series of contact pins or wires. The contact pins are usually made of copper or brass and are designed to provide an electrical connection between the two connectors. When the contact pins are mated, they create a connection that is resistant to noise, shock, and vibration.

The contact pins are held in place by a spring clip or retainer, which is usually made of nylon or stainless steel. This clip or retainer ensures that the contact pins are firmly held in place and that the connection is secure. The spring clip also helps to prevent accidental disconnections.

Some rectangular connectors also feature contacts that are machined into the housing itself. This is typically used when the contact pins are not an option or when the contact pins do not fit the application. Machined contacts are usually made of copper or a copper alloy and are also resistant to noise, shock, and vibration.

Conclusion

Rectangular Connectors - Housings provide a secure and reliable electrical connection between two dissimilar devices or systems. They are used in a wide variety of applications, and they come in a variety of shapes and sizes with various features. It is important to select the right type of housing for the intended application in order to ensure the connection is secure and reliable.
