Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not paid
Embodiment, belongs to the scope of protection of the invention.
The basic three-dimensional structure of the overall body contact formula fin in crystal cover series electromagnetic relay proposed by the present invention is such as
Shown in Fig. 2, fin b global designs are four parts such as supporting plate b1, contact heat sink b2, connecting plate b3, banking stop b4, even
Fishplate bar b3 has connected contact heat sink b2 and supporting plate b1, and supporting plate b1 is vertical with connecting plate b3 to be connected, round-corner transition, heat sink
B2 uses circular-arc-shaped design, with relay1 case good contact.The design of circular arc also makes the fin there is certain vibration damping to imitate
Really.This four part of supporting plate b1, heat sink b2, connecting plate b3, banking stop b4 is using aluminum or aluminum alloy as making material, table
Face electrogalvanizing.
During specific assembling, fin b is welded together by the way of spot welding with electromagnetic system a, as shown in Fig. 3 to Fig. 7.
Welding position is between support feet a1 and banking stop b4, by the fixation of banking stop b4 and the side holding position of support feet a1.
The lower edge of the lower edge of supporting plate b1 and the support feet a1 of electromagnetic system a leaves a difference in height, the numerical value of the difference in height with after
The base plate c1 consistency of thickness of the contact system c of electrical equipment, it is ensured that install the electromagnetic system a and contact system c of fin b
Base plate c1 is brought into close contact.
Fig. 7 show the integral installation schematic diagram of fin, and each Crystal Can Relay installs 2 fin, fin b
Connecting plate b3 present positions be the surface of contact system c stationary contacts c2 and movable contact spring c3, the coil a2 and yoke of electromagnetic system a
The underface of iron a3, can intercept the hot-fluid between contact system and electromagnetic system；The contact heat sink b2 and shell of fin b
D is in close contact, and can conduct to casing part many residual heat streams；The support feet a1 of the supporting plate b1 and electromagnetic system a of fin b
It is brought into close contact, conducts and balance the heat between the different groups transfer contact of the same side；So as to realize improving heat conduction efficiency, protection electricity
Magnetic system, reduces relay heating, improves the effect with the life-span is carried.Meanwhile, the contact heat sink b2 of circular arc can play slow
The effect of punching, improves the resistance to shock of electromagnetic relay.
The design procedure of the overall body contact formula fin in crystal cover series electromagnetic relay of the invention is as follows：
Step 21：Fin b is made, is formed by block of metal sheet material panel beating, can suitably adjusted according to relay space
Whole sheet metal thickness, sheet material material is using aluminum or aluminum alloy as making material, plating zinc on surface；Fin b is by supporting plate b1, contact
Heat sink b2, connecting plate b3, tetra- parts of fin b4 constitute, and contact heat sink b2 uses circular-arc-shaped design, connecting plate b3 to connect
Contact heat sink b2 and supporting plate b1 is picked up, supporting plate b1 is vertical with connecting plate b3 to be connected, round-corner transition；The design of fin b
Size on the basis of the factors such as specific relay gauge size, debud mode are considered, with relay electro-magnetic system with contact system
Space matches between system.
Step 22：Fin b is welded together by the way of spot welding with electromagnetic system a, and welding position is support feet a1
Between banking stop b4 so that banking stop b4 keeps contacting with the side of support feet a1.The lower edge of supporting plate b1 and electromagnetic system
The lower edge of the support feet a1 of system a leaves a difference in height, the base plate c1 thickness of the contact system c of the difference in height numerical value and relay
Unanimously, it is ensured that the electromagnetic system a for installing fin b can be brought into close contact with the base plate c1 of contact system c；
Step 23：The electromagnetic system a and contact system c that upper fin b will be welded are installed together, and complete the whole machine of relay
Install；
Step 24：During relay carry load work, fin b causes the contact system c of relay in adhesive and release process
The heat of middle generation is absorbed by fin b, transmits and derive to outside relay, and it is right that the high temperature that decrease pitting of contact is produced is persisted
The continued damage of contact system；Isolation contact system c and electromagnetic system a, weaken pitting of contact to electromagnetic system a especially coils
The damage of a2, it is to avoid coil a2 overheats cause ampere-turn to decline, guard relay continuous action ability, the comprehensive longevity for improving relay
Life.Meanwhile, the contact heat sink b2 of circular arc can play a part of buffering, improve the resistance to shock and stabilization of electromagnetic relay
