Coaxial connectors are frequently used for radio frequency signal connections. The 1051085-1 connector is one of the most common and well-developed coaxial connectors, widely used in different fields from military to communications and consumer electronics. The connector’s application fields and working principle can be described as follows.

Application Field

This 1051085-1 connector is especially suitable for radio frequency and high-speed digital signal applications. It is especially used in military standard field, which requires a certain connector for the electrical and/or waterproof performance. With the help of 1051085-1 connector’s specific characteristics, the connector can meet the requirements of military standard. Moreover, the connector also appears in various consumer electronics and communication equipments, especially the higher speed wireless communication devices such as 4G phone, Wi-Fi router and wireless flying collector.

Working Principle

A coaxial connector consists of a male and a female connector, each of them contains several sub-components. Both the male and female part of the 1051085-1 connector are constructed of a center conductor, an insulator and a metal shield. Among them, the center conductor serves as the signal path, the insulator isolates the center conductor from the shield, and the shield is connected to ground. In order to ensure the correct and reliable electrical performance, the male and female parts of the connector are designed to form a firm connection only when the male part is totally inserted into the female part and the metal shield is tightly connected with each other.

Inside the coaxial connector, there usually exists cantilever spring contact. For the 1051085-1, it employs a 1.8mm circular gold contact. It supports a wide operating temperature range and provides an effective electrical connection between male and female parts. Together with the large touch area, this kind of gold contact offers an excellent performance in terms of electrical and mechanical properties such as anti-migration, electrical endurance and surge performance.

1051085-1 has two versions, one is Screw and the other is PCB. It is a low cost way to achieve the best high-frequency performance and features. The connections made with either style are similar and the assembly steps are the same. The two versions have different applications, as the Screw version mainly applies to the lower frequency frequency (200 MHz), while the PCB version can achieve higher frequency connections (2.4 GHz).

Based on the above analysis, it can be concluded that 1051085-1 connector, as one of the most frequently used and well-developed RF connectors, is quite versatile in its application fields and its working principle is also reasonably designed for the best performance. Its PCB version is particularly required for higher frequency connections, such as signals used for 4G and Wi-Fi.
