Switch-type coaxial connector

Abstract

The invention discloses a switch-type coaxial connector. The switch-type coaxial connector comprises an insulation substrate, an insulation body, a fixed terminal, a movable terminal and a metal shell, wherein the fixed terminal and the movable terminal are clamped between the insulation substrate and the insulation body, the insulation substrate and the insulation body are fixed by the metal shell, the insulation body is provided with a first side and a second side which are opposite to each other, the fixed terminal is arranged at the first side of the insulation body, the movable terminal is arranged at the second side of the insulation body and is provided with a contact part, a gap is encircled by a first side arm, a second side arm and a third side arm of the fixed terminal, and a tail end of the movable terminal extends to a lower side of the gap. The fixed terminal forms a surrounding structure, the gap accommodated with the tail end of the movable terminal is formed, the occupancy space of the movable terminal on the connector is reduced, and miniaturization development of the switch-type coaxial connector is achieved.

Description

[0002] For the prior art related to the present invention, please refer to the Chinese Invention Patent No. CN104471802B announced on October 19, 2016, which discloses a coaxial connector It is a coaxial connector to which a coaxial connector for inspection is attached. The coaxial connector for inspection has a probe extending in the vertical direction and a cylindrical first outer conductor surrounding the probe. The coaxial connection The device includes: a main body having an upper surface and a bottom surface, and a hole for inserting the above-mentioned probe from the upper side to the lower side; a second outer conductor including a periphery surrounding the hole and inserted into the first outer conductor. A cylindrical part inside the conductor, an outer conductor body part provided on the above-mentioned upper surface, and an outer conductor fixing part clamping the above-mentioned body together with the outer conductor body part by being drawn out from the outer conductor body part to the above-mentioned bottom surface; a fixed terminal , which is fixed to the main body; and a movable terminal including a movable terminal fixing portion fixed to the main body, and a leaf spring portion extending from the movable terminal fixing portion toward the fixed terminal, And the branch is formed with a branch part to contact the fixed terminal. When the branch part is used to support the center terminal when plugged in, the movable terminal has elastic support to prevent elastic fatigue and affect the service life of the connector. However, the branch part is towards Extended on both sides, thereby increasing the overall width of the connector, which is not conducive to the miniaturization of the connector

[0003] In addition, China Utility Model Patent Announcement No. 203071298 discloses a radio frequency head with a movable terminal and a fixed terminal. The movable terminal and the fixed terminal are respectively There is an upwardly extending contact arm to improve the phenomenon of solder creeping of the RF head during soldering and prevent the two contact arms from being connected together by solder. However, the upwardly extending contact arm increases the height of the RF head and is not suitable for the development of miniaturization
