HMTSW-140-21-S-Q-740 Connectors: Application Field and Working Principle

Parallel board-to-board connectors in the form of rectangular headers with male pins are widely used in many industrial applications when interconnecting printed circuit boards (PCBs). In particular, connectors of the HMTSW-140-21-S-Q-740 series, produced by ITT Cannon, are becoming increasingly popular due to their reliability and versatility. This article explains the main application field of HMTSW-140-21-S-Q-740 connectors and details their working principle.

Application Field:

HMTSW-140-21-S-Q-740 connectors are commonly used for signal and power transfer between printed circuit boards. Typically, they are used in power distribution systems where signals need to pass through several circuit boards to reach their destination. These connectors can also be used in networking applications such as telecommunications and data transmission. Additionally, these connectors can be used in medical and automotive applications, where reliable and durable connections are desirable.

Working Principle:

The working principle of HMTSW-140-21-S-Q-740 connectors is fairly simple. The connectors consist of two parts: one part is the male pin and the other part is the female socket. The male pins of the connector feature a stepped design, which allows the pins to be firmly inserted into the female socket. The female socket features guide ribs on its interior walls, which helps to ensure a secure fit. The two parts are held together by a plastic housing that wraps around both the male pin and the female socket. When the HMTSW-140-21-S-Q-740 connector is assembled, the male pin and the female socket make physical contact, which results in an electrical and/or mechanical connection. The electrical connection is made possible by the metal terminals found on the ends of the male pins. These terminals provide a pathway for electrical current to flow between the two boards that are being connected. The mechanical connection between the two parts is achieved through the friction fit of the plastic housing. The plastic housing acts to keep the two parts in a secure, connected position.

Conclusion:

In conclusion, HMTSW-140-21-S-Q-740 connectors are versatile and reliable rectangular board-to-board connectors with male pins and female sockets that are widely used in many industrial applications. Their working principle involves the secure fit of the male pin and the female socket within a plastic housing, resulting in an electrical and/or mechanical connection between the two boards.
