EJH-120-02-L-D-TH Application Field and Working Principle

Rectangular Connectors, also known as Headers, are a type of electrical connector consisting of one or more rows of metal pins or sockets. Headers can come in various shapes, such as round, square, hexagonal, or rectangular. The EJH-120-02-L-D-TH is a type of rectangular header, specifically Male Pins, and is often used in a variety of applications. This article will discuss the application fields and working principles of this type of rectangular header.

Applications

The EJH-120-02-L-D-TH is commonly used in a variety of applications, such as PCB backplanes, embedded system boards, and electronic devices. This type of header is also suitable for applications that require high-density packing, such as networking and automotive systems. In addition, the EJH-120-02-L-D-TH can be used in lower-end applications due to its relatively low cost.

Working Principles

The working principles of the EJH-120-02-L-D-TH is based on the basic principles of Direct Pin Array Connections. The pin array consists of a series of aligned pins or sockets, typically arranged in rows. The pin array is designed to create an electrical connection between the pins and the socketed contacts. When the pin array is inserted into the socketed contacts, the contacts are held in place by the pins, thus creating a secure electrical connection.

The connector also contains a locking mechanism that further secures the pins to the socketed contacts. The locking mechanism typically consists of two components: a plunger that holds the pins in place, and a spring that actuates the plunger. When the connector is inserted into the socketed contacts, the plunger is actuated by the spring and locks the pins in place, thus providing a secure connection.

In summary, the EJH-120-02-L-D-TH is a type of rectangular header suitable for a variety of applications. It is based on the principles of Direct Pin Array Connections, which use a series of pins or sockets to create an electrical connection between the pins and the socketed contacts. The connector also features a locking mechanism that secures the pins in place for a secure electrical connection. It is a relatively low-cost connector, making it suitable for use in lower-end applications.
