[0027] Example:
[0028] As attached Figure 1 To Attachment Figure 5 As shown:
[0029] The utility model provides a convenient assembled vehicle relay, comprising a housing 1, a bottom plate 3, a coil 4, a moving contact fixing plate 5, a contact fixing plug plate 6 and a resistor 7;

The static contact 602 is inserted and fixed in the through slot; a slot is provided at the lower end of the coil 4, a coil winding 401 is provided on the winding column in the middle of the coil 4, and a moving contact fixing plate slot is provided at the upper end of the coil 4; the moving contact fixing plate 5 is inserted in the moving contact fixing plate slot at the upper end of the coil 4, a semicircular spring leaf 5001 is provided at the front end of the moving contact fixing plate 5, a through slot is provided at the rear end of the moving contact fixing plate 5, a group of supporting springs 501 is provided in the middle of the through slot, and two groups of moving contact fixing pins 502 are provided at both ends of the through slot.
[0031] Among them, Figure 2 As shown, a group of moving contacts 503 are welded at the lower end of the semicircular spring 5001, which can allow the moving contacts 503 to automatically reset after the coil 4 is powered off.
[0032] Among them, Figure 3As shown, a group of reed pieces 603 are respectively welded to the lower ends of the normally closed static contact 601 and the normally open static contact 602, which can prevent poor contact during installation and increase the structural reliability.
[0033] Among them, as Figure 2 shown, a resistor 7 is provided inside the component fixing post 303.
