Introduction of 1.85mm connectors and the correct way to use them

1.85mm connectors are a smaller version of 2.4mm, 1.85mm is the inner diameter of its outer conductor, originally designed for 67GHz, but can work up to 70GHz. 1.85mm connectors are selected with M7 thread, which can be compatible with 2.4mm. Many experts believe that this connector is the smallest coaxial connector possible to reach 67GHz for general use.

Introduction of 1.85mm connectors

The construction of 1.85mm connectors is divided into male or female connectors with impedance specifications of 50 ohms. 1.85mm connectors are available in threaded, 2-hole panels or no-load profiles. The termination of these 1.85mm connectors is snap/solder or field replaceable. The interface mainly uses air dielectric with a support bead that is located in the body of the connector to reduce the bead interaction in the match. As with the 2.92 mm and 2.4 mm connectors, the design concept is to ensure that the outer conductor is connected before the center conductor makes contact. 1.85 mm connectors are selected with M7 threads and are only compatible with 2.4 mm connectors. 1.85 mm connectors are a smaller version of 2.4 mm connectors and are mechanically compatible with 2.4 mm connectors and have the same robustness. Although mechanically compatible, we still do not recommend mixing connectors. Due to the different frequency and tolerance requirements of each connector, there are various risks of mixing connectors, affecting the service life, and even damaging the connector, which is the last resort.

The proper use of 1.85mm connectors

First, when you receive the 1.85 mm connectors, we must carefully observe the outer packaging to see if there is obvious damage to the place, but also to see if there will be damage to the connector itself and so on. To ensure that they see the connector is intact so that we will not affect the use of even the machine.

Second, temporarily do not use the 1.85 mm connectors, and do not randomly place the connector, especially casually placed in a sunny place. So that because of negligence forget to place it, the connector will be a long time sun exposure to the quality of damage. Thus affecting his use, and even safety accidents, so we must carefully remember where the connector can be saved, do not be careless and mistakes.

Third, in high-temperature places, it is not possible to place the 1.85 mm connectors, sustained high temperature or high humidity, will damage the connector, especially with chemicals in the environment. The connector will be corroded, so that the outside of the metal protective layer lost the role of protection, destroying the current line inside, without the normal function of electrical conductivity. It has become a waste.

Fourth, the need to move the 1.85 mm connectors, not panic, and be careful to avoid touching the connector to hard objects, causing damage to the connector. And not to put it under heavy objects, so as not to crush the connector.
