Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of not making the creative labor
Embodiment shall fall within the protection scope of the present invention.
Basic three-dimensional structure such as Fig. 2 institutes of through cooling fin in crystal cover series electromagnetic relay proposed by the present invention
Show, cooling fin b global designs are support plate b1, heat sink b2, tri- parts connecting plate b3, and connecting plate b3 has connected dissipating for both sides
Hot plate b2, support plate b1 and b2 heat sink vertical connection, round-corner transition, heat sink b2 penetrate through entire relay one-side contact region
Top, connecting plate b3 connections two groups of support plate b1, support plate b1, heat sink b2, tri- parts connecting plate b3 are all made of copper or copper
Alloy is as making material, electroplating surface zinc.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, through cooling fin b of the invention is by the way of spot welding and electromagnetic relay
In electromagnetic system a weld together, welding position be electromagnetic system a support leg a1 and cooling fin b support plate b1 between,
There are a difference in height, the difference in height numerical value for the lower edge of the perforation long side side of connecting plate b3 and the a1 support legs of a electromagnetic systems
With the consistency of thickness of the bottom plate c1 of the contact system c of electromagnetic relay so that the electromagnetic system a for installing cooling fin b can be with
The bottom plate c1 of contact system c is fitted closely.
Fig. 7 show the integral installation schematic diagram of the Crystal Can Relay cooling fin of the present invention, the connecting plate b3 of cooling fin b
Present position is the surface of the stationary contact c2 and movable contact spring c3 of contact system c, and the coil a2 and yoke a3 of electromagnetic system a are just
Lower section penetrates through same contacts side space in form, obstructs the hot-fluid between contact system c and electromagnetic system a；The branch of cooling fin b
The support leg a1 of fagging b1 and electromagnetic system a is fitted closely, and is conducted and is balanced the heat between different groups of transfer contact；To reach
Heat conduction efficiency is improved, electromagnetic system is protected, relay fever is reduced, improves with the effect for carrying the service life.
The design procedure of the through cooling fin of crystal cover series electromagnetic relay of the present invention is as follows：
Step 21：Cooling fin b is made, is formed by block of metal sheet fabrication, plate thickness is depending on relay space, plate
Material material is using copper or copper alloy as making material, electroplating surface processing；Cooling fin b is by support plate b1, heat sink b2 and company
