Problems solved by technology

[0003] The method usually used in the preparation of RF connectors is to weld the RF terminals that meet the requirements on the shell with metal solder. The welding temperature is relatively low, which can ensure the RF performance and sealing performance of the connector, but the process is more complicated. It needs to be gold-plated in advance, and it is prone to defects such as splashing and inaccurate positioning

Abstract

The invention relates to a radio frequency connector and a manufacturing method thereof, which relate to the field of signal transmission and aims at requiring no brazing and no gold plating when the radio frequency connector is manufactured and ensuring the positioning precision and the packaging air tightness of the radio frequency connector. According to the technical scheme adopted by the invention, conductive sealing glass powder, the conductive sealing glass powder and an organic binder are mixed, granulation is carried out, and granulation powder is formed; according to the appearance of a radio frequency terminal, the granulation powder is manufactured into a conductive sealing glass perform; and the conductive sealing glass perform is placed between the radio frequency terminal and a shell and is heated to a sealing temperature, the conductive sealing glass perform is thus combined with the radio frequency terminal and the shell respectively. According to the radio frequency connector manufacturing method, through manufacturing the conductive sealing glass perform and heating the conductive sealing glass perform, the conductive sealing glass perform is in a melt state, the radio frequency terminal is thus sealed with the shell, and the method can ensure the air tightness and the radio frequency performance of the radio frequency connector, accurate positioning and high reliability.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to a radio frequency connector and a preparation method thereof. Background technique [0002] With the continuous development of science and technology, technologies such as radar technology and satellite communication have higher and higher requirements for the signal transmission quality of signal transmission hardware. As a key component of transmitting signals in systems such as radar, high-speed data processing, and satellite communications, RF connectors have a direct impact on the quality of transmitted signals. RF connectors must achieve extremely high reliability in order to meet the stability requirements of the entire system. [0003] The method usually used in the preparation of RF connectors is to weld the RF terminals that meet the requirements on the shell with metal solder. The welding temperature is relatively low, which can ensure the RF performance and sealing...
