Condition, and the number of parts that traditional relay uses is many, assembles comparatively laborious, wastes more resources, repairs
Also inconvenient, increased workload to staff.
Content of the invention
The purpose of this utility model is to provide a kind of closed electromagnetic relay, to solve to propose in above-mentioned background technology
Problem, had an advantageous effect in that：Structure is simple, and the number of parts used is less, easy to assembly, economizes on resources, to work
Bring facility as personnel.
For achieving the above object, this utility model provides following technical scheme：A kind of closed electromagnetic relay, the bottom of including
Seat, yoke terminal, coil terminals, reed and armature, described base is installed with first support and second support, and iron core
It is connected with yoke through after second support and first support, described iron core is wound with coil, described first support is fixed with
The copper wire of coil is wound with reed and coil contact, and coil contact, described yoke terminal is connected through base with yoke, institute
The one end stating yoke is provided with armature, and one end of reed is fixed on armature, and the side of described reed is provided with movable contact, institute
Stating fixing iron plate in second support has two, and is respectively arranged with normally-closed contact and normally opened contact on iron plate, described coil-end
Son passes through base and coil contact portion, and normally opened contact terminal and normally-closed contact terminal are connected through base with iron plate.
Preferably, described yoke terminal, coil terminals, normally opened contact terminal and normally-closed contact terminal are arranged under base
Side.
Preferably, described movable contact is arranged between normally-closed contact and normally opened contact.
Preferably, described first support and second support are all perpendicular to base.
Compared with prior art, the beneficial effects of the utility model are：This equipment is provided with movable contact, normally-closed contact and often
Open contact, in the case that coil is not energized, movable contact and normally-closed contact close, and normally opened contact disconnects, and motor stops
Work, during coil electricity, movable contact moves, and makes original closure state become off-state, off-state originally becomes closes
Conjunction state, motor is started working, and structure is simple, and the number of parts used is less, easy to assembly, economizes on resources, to work people
Member brings facility.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-5, a kind of embodiment that this utility model provides：A kind of closed electromagnetic relay, including base
5th, yoke terminal 6, coil terminals 7, reed 14 and armature 16, base 5 is installed with first support 2 and second support 10,
And iron core 3 is connected with yoke 4 through after second support 10 and first support 2, iron core 3 is wound with coil 1, in first support 2
Be fixed with the copper wire that coil 1 is wound with reed 14 and coil contact 17, and coil contact 17, yoke terminal 6 pass through base 5 with
Yoke 4 connects, and one end of yoke 4 is provided with armature 16, and one end of reed 14 is fixed on armature 16, and the side of reed 14 sets
It is equipped with movable contact 13, in second support 10, fixing iron plate 11 has on two, and iron plate 11 and is respectively arranged with normally-closed contact 12 He
Normally opened contact 15, coil terminals 7 are connected through base 5 with coil contact 17, and normally opened contact terminal 8 and normally-closed contact terminal 9
It is connected through base 5 with iron plate 11, yoke terminal 6, coil terminals 7, normally opened contact terminal 8 and normally-closed contact terminal 9 are arranged on
The lower section of base 5, movable contact 13 is arranged between normally-closed contact 12 and normally opened contact 15, and first support 2 and second support 10 are all
