Abstract

The invention discloses an electromagnetic drive structure for a satellite-borne DP3T microwave switch. The electromagnetic drive structure comprises hexagon nuts, an electromagnetic group, a cover plate bracket group, an armature group and small shafts, wherein the cover plate bracket group is provided with four support studs and two mounting bosses; the electromagnetic group is fixed on the foursupport studs of the cover plate bracket group through the hexagon nuts; the armature group is arranged on the mounting bosses of the cover plate bracket group through the small shafts; and coil assemblies are combined and energized according to a certain principle and the armature group is driven to carry out spinning movement, thereby achieving an electromagnetic drive switching function of thesatellite-borne DP3T microwave switch. According to the electromagnetic drive structure for the satellite-borne DP3T microwave switch, the electromagnetic drive structure achieves electromagnetic drive of four paths of radio frequency channels by adopting three cores; the structure is compact; the small and lightweight design of the satellite-borne DP3T microwave switch is achieved; and the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of microwave switches, and in particular relates to an electromagnetic drive structure of a star-borne DP3T microwave switch. Background technique [0002] The on-board DP3T microwave switch consists of 4 radio frequency channels. The electromagnetic drive structure of the traditional DP3T microwave switch is composed of yoke iron, four iron cores, and four coils. Each iron core is equipped with a coil group. Alternatively, it can be fixed on the yoke by means of screw connection, so as to realize the three-state switching of the radio frequency channel. The traditional electromagnetic drive structure is complex and bulky, which affects the structural size and performance of the radio frequency channel. The electromagnetic drive structure has become a bottleneck that limits the miniaturization and reliability of the on-board DP3T microwave switch. Contents of the invention [0003] The technical problem o...
