Time sequence control cabinet

Abstract

The invention relates to the technical field of aerospace, particularly to a time sequence control case, which comprises a case main body, a first electric connector, a second electric connector, a circuit board assembly, six electromagnetic relays and six circuit breakers, wherein the first electric connector, the second electric connector, the circuit board assembly, the six electromagnetic relays and the six circuit breakers are installed in the case main body, the case main body is a cuboid, box plates of the case main body are fixedly connected through screws, sealing gaskets are extruded at the butt joint positions of the box plates, a first mounting plate parallel to a case left box plate is mounted on a case bottom plate, a plurality of metal clamping grooves distributed at intervals are symmetrically formed in the first mounting plate and the case left box plate, the case main body further comprises a second mounting plate, the second mounting plate is parallel to the case bottom plate, the two ends of the second mounting plate are fixedly connected with the metal clamping grooves in the first mounting plate and the metal clamping grooves in the case left box plate respectively, and an electromagnetic relay and a circuit board assembly are fixed to the second mounting plate. The time sequence control case of the invention has the advantages of avoiding overlarge starting current of a plurality of external loads at the same time and the like.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a timing control cabinet. Background technique [0002] With the increasing demand for control equipment in the military industry, the requirements for control equipment are also getting higher and higher. Most of the existing control equipment has poor resistance to electromagnetic environments and is susceptible to electromagnetic interference; most of the timing control chassis in the prior art The mechanical strength is low, the control function is single, the weight and volume are large, and the requirements for the use environment are high, which cannot meet the use requirements of military equipment. Contents of the invention [0003] In order to solve the above problems, the present invention provides a sequence control cabinet, which has the advantages of preventing multiple external loads from starting too much current at the same time. [0004] In order to achiev...
