Larger current processed, a kind of automatic switch of higher voltage.Therefore play in circuit automatically adjust, safeguard protection, change-over circuit
Deng effect, electromagnetic relay uses in field, and most of electromagnetic relays are by coil, bobbin, yoke, iron core and armature etc.
The electromagnetic system of part composition, coil two ends produce electromagnetic field and magnetic flux by connecting voltage, and iron core is because electromagnetism magnetizes
Produce electromagnetic force, inhale moving armature and make electromagnetic relay produce mechanical action.Due to having to the anti-shake performance of electromagnetic relay
Strict requirements are therefore higher to the Structural Design Requirement of electromagnetic relay.But the yoke of existing electromagnetic relay knot
Structure design is unreasonable, and this miniature electro-magnetic relay assembly process is more numerous and diverse, and its anti-seismic performance is also poor.
Utility model content
The purpose of this utility model is to provide a kind of electromagnetic type relay, with solve in above-mentioned background technology propose ask
Topic.
For achieving the above object, this utility model provides following technical scheme：A kind of electromagnetic type relay, including base,
Iron core and shell, the bottom of described shell is provided with described base, described base is provided with contact reed, described contact reed
Bottom the first leading foot is installed, the both sides of described first leading foot are provided with the second leading foot, the one of described contact reed
Side is provided with U-shaped armature, and described U-shaped armature is provided with described iron core, and described iron core is provided with coil, the top of described iron core
Portion is provided with support with the top of coil, and described contact reed top is provided with the second contact, the top peace of described second contact
Equipped with the first contact, the lower section of described second contact is provided with the 3rd contact, and described first contact is arranged on the first L-type yoke
On, the bottom of described first L-type yoke is provided with the 3rd leading foot, and described 3rd contact is arranged on the second L-type yoke, described
The bottom of the second L-type yoke is provided with the 4th leading foot.
Further, described coil is made using copper cash.
Further, described shell, support and base are integrated injection moldings.
Further, described first contact and the second contact contact with each other in no power.
Compared with prior art, the beneficial effects of the utility model are：The shell of this kind of equipment, support and base are one
Injection mo(u)lding, convenient installation, improve production efficiency, add certain voltage at the two ends of coil, in coil, will pass through one
Fixed electric current, thus producing galvanomagnetic-effect, U-shaped armature overcomes the pulling force returning contact reed to inhale in the presence of electromagnetic attracting force
To iron core, thus driving the second contact and the 3rd contact adhesive of contact reed bottom.After coil blackout, the suction of electromagnetism
Disappear therewith, contact reed has certain elasticity, make U-shaped armature return to original position, so that the second contact is touched with first
Point adhesive, such adhesive, release, thus having reached conducting in circuit, the purpose of cut-out, there is structure design compact and have
Effect improves the feature of anti-seismic performance.

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, this utility model provides a kind of technical scheme：A kind of electromagnetic type relay, including base 3, ferrum
Core 6 and shell 16, the bottom of shell 16 is provided with base 3, and base 3 is provided with contact reed 4, the bottom peace of contact reed 4
Equipped with the first leading foot 2, the both sides of the first leading foot 2 are provided with the second leading foot 1, and the side of contact reed 4 is provided with U-shaped rank
Ferrum 5, U-shaped armature 5 is installed cored 6, and iron core 6 is provided with coil 7, and the top of the top of iron core 6 and coil 7 is provided with props up
