226853-3 Coaxial Connectors (RF) - Contacts

• Application Field

  226853-3 coaxial connectors are typically used in applications that require low insertion losses and high shielding effectiveness, making them particularly suited for telecommunications. The 226853-3 coaxial connector is also suitable for use in test, control, calibration, and Avionics applications due to its size and reliable performance. Common applications for the 226853-3 include military and aerospace uses, automotive and industrial applications, as well as cell phones and other portable devices.

  The 226853-3 connector is also used in applications where high impedance is a must, such as in RF shielded test chambers. This is possible due to its low contact resistance, which significantly reduces the amount of energy lost through the contacts.

  In addition, the 226853-3 coaxial connector can be used with a variety of cables, such as both single-conductor and multi-conductor coaxial cables, as well as twisted pair, flat ribbon, and round conductor cables.

• Working Principle

  The working principle of the 226853-3 coaxial connector follows the same principles as other types of shielded coaxial connectors. The basic idea is to use a coaxial body that contains one or more center pins, surrounded by an annular sleeve component, with a layer of outer shielding. The contact between the center pin and the outer sleeve is maintained through the annular space, providing an effective seal to prevent EMI noise from entering the signal.

  The 226853-3 connector is typically designed with a two-piece chuck utilizing reversible setscrew retention. This provides a secure contact between the center pin and the outer sleeve, ensuring that the connection remains tight and providing a consistent connection over time. The two-piece chuck also allows for easier access to the center pin in cases where the contact requires a rework.

  The 226853-3 coaxial connector also features an internal stress relief feature to help reduce mechanical stress on the connector. This is done by providing a uniform and balanced compression on the center pin and outer sleeve, reducing the amount of stress applied to the connection. This helps to reduce the possibility of signal loss and unwanted EMI leakage.
