Rectangular Connectors - Headers, Male Pins are an essential component used in a variety of devices for the purpose of securely connecting wired circuits. Among them, the 147118-2 specification defines a board-to-board male header connector that provides robust mechanical and electrical connectivity.

The 147118-2 connector is a 31-pin version designed for a nominal voltage of 30V and a continuous current of 0.5A. It is a two-part connector consisting of plastic pins (male portion) and plastic headers (female portion). The pins and the headers are available in various lengths and terminal densities in order to meet different electrical and mechanical needs.

In terms of its physical structure, the 147118-2 male header consists of an upper dielectric, several lenses, a lower dielectric, several circuit contacts, an isolation sleeve, a cable seal and a grounding shield. The upper dielectric isolates the connector pins from the environment, and the lenses are designed to adjust the distance between the terminals and ensure material compatibility, and to ensure electrical insulation. The lower dielectric provides electrical conduction and insulation, stabilizes the geometry of the connector and supports the contact forces applied to the contact. The contact is made of a spring element with several ridges for a firm connection during mating. The isolation sleeve provides electrical isolation between the cable conductor and the environment. The cable seal helps to secure the cable to the connector with a cable tie or similar device. The grounding shield provides an electrical connection to the other housing.

The 147118-2 connector is mainly used in applications involving circuit boards and cables, such as telecommunications, computers, instrumentation and test & measurement equipment. In general, 147118-2 headers provide good electrical performance such as low contact resistance, high dielectric strength and low insertion force. The low insertion force makes it easy to mate and un-mate the connector, while the high dielectric strength protects the connection from external electrical interference.

The working principle of the 147118-2 connector is simple and reliable. When two components of the connector are mated, the contact element of the male pin contacts with the contact element of the female header and the barrier ring isolates the contacts from each other. At this point, a gas-tight electrical connection is established between the two components. The contact element maintains a reliable connection even when vibration is present. Furthermore, the connection is also gas-tight, making it ideal for a variety of applications in which moisture protection is necessary.

The 147118-2 connector is an essential component for the connection of wired circuits. Its robust mechanical and electrical properties make it suitable for a variety of applications in which vibration, moisture and electrical interference are involved. The simple and reliable working principle of the connector ensures a reliable connection and protection from environmental factors.
