Problems solved by technology

[0002] The original structure of the electromagnetic power main switch has low excitation coil resistance, high switch operating current, and high internal temperature after long-term operation, especially the poor sealing of the bottom connection of the switch shell, which is easy to seep into water, resulting in internal corrosion and hidden quality problems. Seriously make the switch not work properly
In addition, the current electromagnetic main switch has poor ability to resist external interference

Abstract

A electromagnetic power-source master switch, that is: the outer shell fixes on the bracket, the outer shell includes: the base total parts, the contact total parts, the flange plate, the loop groupware, the iron core, the underboarding, the flange plate sets on the top of the loop groupware, the contact total parts sets on the flange plate, the base total parts covers on the top of the contact total parts, the base boundary connects with the flange plate and sets the sealing ring at the connection, the iron core fixes in the loop groupware, the bottom of the loop groupware sets the underboarding covering on the loop groupware, between the iron core, the underboarding and the underside of the outer shell groupware sets copper underlay. The copper underlay sets in the loop groupware and clings at the underboarding closely with the separating magnetism and antijamming function. The invention is: collects the magnetic force line to the center of the iron core and improves the electromagnetism suction because of adding the underboarding parts; adds the copper parts with the separating magnetism and antijamming function.

Description

technical field [0001] The invention relates to an automobile accessory, which is mainly an electromagnetic power main switch, which is used to connect or cut off the power supply of the whole vehicle. technical background [0002] The original structure of the electromagnetic power main switch has low excitation coil resistance, high switch operating current, and high internal temperature after long-term operation, especially the poor sealing of the bottom connection of the switch shell, which is easy to seep into water, resulting in internal corrosion and hidden quality problems. Seriously, the switch cannot work normally. In addition, the current electromagnetic main switch has poor ability to resist external interference. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical defects and provide an electromagnetic main power switch with reliable performance, reasonable structure and long service life. [00...
