Embodiment Construction

[0012] Put the metal gasket 2 on the miniature magnetic latching relay 1, glue the metal gasket 2 and the insulating gasket 3, and put a little glue on the metal gasket 2 and the miniature magnetic latching relay 1, after the glue is cured, three The components are formed into one, and then welded to the circuit board, and the insulating gasket 3 is closely attached to the circuit board. After the soldering is completed, place the metal pad 2 on the figure 1 Spot-weld a grounding wire at the indicated position, and then guide the wire to the casing and fix it. That is, the grounding operation process is completed.

Abstract

The invention discloses a miniature magnetic latching relay ground structure for a geosynchronous orbit. The ground structure comprises a conducting grounding part and an insulating mounting part. A metallic gasket and a miniature magnetic latching relay are installed in a fit mode. A metallic housing of the miniature magnetic latching relay and a case are in a conducting state by a ground wire welded to the metallic gasket. Besides, an insulating spacer is installed at the outer side of the metallic gasket and is in contact with a circuit board, thereby realizing insulating mounting of the metallic housing of the miniature magnetic latching relay on the circuit board. With the structure, grounding of the metallic housing of this type of the relay and the case and insulating mounting of the metallic housing of the relay on the circuit board can be realized. Moreover, the ground structure has advantages of light weight, convenient operation, and high reliability and is capable of standing the test of a space environment.

Description

technical field [0001] The invention relates to a grounding structure of a miniature magnetic holding relay for a geosynchronous orbit, in particular to a structure form and a material, and is mainly applied to a space remote sensor of the geosynchronous orbit. It fundamentally solves the problem of grounding the metal casing of the miniature magnetic latching relay and the casing, and at the same time insulating and installing on the circuit board. Background technique [0002] The high temperature and low density of space plasma in geosynchronous orbit is accompanied by geomagnetic substorm activities, and remote sensors are faced with serious surface charge and discharge problems. features. In order to avoid the serious danger of deep charge and discharge of the remote sensor, reduce the impact of space electrostatic discharge on the remote sensor, and meet the requirements of electromagnetic compatibility, the corresponding protection design must be carried out for the ...
