[0001] The present application relates to the technical field of electrical connection, and in particular to a miniature dual elastic contact connector and a micro switch. Background Art
[0002] In recent years, with the continuous miniaturization of electronic products, especially in the field of microwave switches, the electrical interconnection between modules has become an important technical challenge. Traditional large-size standard connectors have been unable to meet the increasingly stringent space constraints and technical requirements, which makes the research and development of new connectors particularly important. Such connectors not only need to have a compact structure, but also need to ensure reliable electrical performance, while being easy to assemble and maintain quickly to adapt to the miniaturization trend of modern electronic products.
[0003] In the existing technology, in order to achieve electrical interconnection between modules inside small-sized electronic products, commonly used methods include but are not limited to: standard connectors, wire welding, and customized spring connection.
[0004] However, although standard connectors have high reliability and standardization, their application scope is greatly limited due to size constraints; although wire welding can achieve more flexible connections, it is easy to cause problems such as cold soldering and poor welding during the welding process, and the operation is complicated, which is not conducive to large-scale production; while customized spring connections can overcome the above problems to a certain extent, they are difficult to design and manufacture, and have poor versatility. These problems lead to difficulties in rapid interconnection between modules, especially in precision equipment such as microwave switches, where the limitations of standard connectors are more obvious and cannot meet the needs of efficient and fast assembly. Summary of the invention
[0005] In order to overcome the shortcomings of the prior art, the present application provides a miniature dual-elastic contact connector, which can improve the reliability and stability of the connector, reduce production costs, adapt to the technical effects of installation in a narrow space, and ensure good connectivity and signal transmission quality, especially in radio frequency signal transmission circuits.
