Abstract

An embodiment of the invention provides a coaxial mercury relay. The coaxial mercury relay comprises a shielding shell, a hollow coil, a first center conductor, a second center conductor, a mercury tube, a coaxial connector and a shielding layer, wherein the hollow coil is arranged on the inner side of the shielding shell; the shielding layer is arranged on the inner side of the hollow coil; the first center conductor, the second center conductor and the mercury tube are all arranged on the inner side of the shielding layer, and the first center conductor and the second center conductor are connected with the two ends of the mercury tube in the central position of the hollow coil respectively; the end parts, not connected with the mercury tube, of the first center conductor and the secondcenter conductor are both connected with the coaxial connector; the coaxial connectors, the first center conductor, the second center conductor and the mercury tube are coaxial; and a high-pressure-resistant insulating material is filled in the shielding layer. The coaxial mercury relay provided by the invention is of a single-pole single-throw type, and the problems that contact points of a current coaxial switch are oxidized, an arc is easily generated and the high-voltage resistance is insufficient are solved; and meanwhile, the problem of impedance mismatching of existing mercury switch ports is solved.

Description

technical field [0001] The invention relates to the technical field of electronic controllers, in particular to a coaxial mercury relay. Background technique [0002] The existing main switching device applied to high-frequency circuits is a coaxial switch. According to the current technology, the transmission loss of the coaxial switch is the smallest, and the transmission signal purity is higher than that of other switches; it can achieve better test results. The main technical method is that the coaxial switch can match the characteristic impedance of the coaxial cable as much as possible inside the component, which is the structural characteristic of the coaxial switch. [0003] At present, the coaxial switches on the market are mainly single-pole double-throw (SPDT), single-pole three-throw (SP3T) and single-pole multi-throw. Arcing phenomenon, insufficient high pressure resistance. Contents of the invention [0004] In view of this, the purpose of the embodiment of...
