Abstract
The utility model relates to an airproof micro electromagnetic relay, which comprises a contact system, an electromagnetic member, an insulative gasket and a cover, all of which are made of compact components. In addition, the glass insulator hole, the dynamic reed assembly and NO/NC reed in the contact system are combined, while the iron core, the yoke iron, the armature iron, the cover plate and the support structure in the electromagnetic member are properly designed and positioned, so that the airproof electromagnetic relay presents compactness and reliability suitable for high-density installation of PCBs.
Description
One, technical field
The utility model belongs to the relay technical field.
Two, background technology
Along with the develop rapidly of Aeronautics and Astronautics technology, space product more and more trends towards miniaturization, microminiaturization and intelligent.This just makes that the space that is used for whistle control system is very limited, and various parts all need reduce volume as far as possible, and original relay is because volume, weight, power consumption, sensitivity etc. are former thereby can't satisfy the instructions for use of certain specific environment.
Three, summary of the invention
The utility model purpose provides little, in light weight, the highly sensitive hermetically-sealed superminiature electromagnetic relay that is applicable to that printed board is installed of a kind of volume, does signal transmission and circuit switching use for Aeronautics and Astronautics and other industry.This relay volume is 1/10 crystal cover, and weight is fit to the high-density installation of pcb board less than 2 grams very much.
For achieving the above object, the utility model hermetically-sealed superminiature electromagnetic relay, except that the parts that adopt ultra-small volume, also adopt following technical proposals:
The utility model hermetically-sealed superminiature electromagnetic relay comprises contact system, electromagnetic mechanism, insulation spacer, outer cover.Position, glass insulator hole on the substrate that contact system comprised is made as and is staggered, and forms centrosymmetric form; Movable contact spring makes up and often opens the spring combination design on same one side of substrate center's line, and normally closed reed design is on the other one side of substrate center's line;
Adopt the hermetically-sealed superminiature electromagnetic relay described in the utility model of said structure scheme to have following advantage:
1, volume is little, and is in light weight;
2, high pressure resistant, anti-impact shake, good insulation preformance
3, be active in one's movements, the contact reliability height.

Five, embodiment
The utility model is described in further detail in conjunction with above-mentioned accompanying drawing illustrated embodiment:
As shown in Figure 1, the utility model hermetically-sealed superminiature electromagnetic relay comprises: contact system 1, electromagnetic mechanism 2, insulation spacer 3, outer cover 4.
The contact system 1 of this relay is often opened spring combination 9 by the normally closed reed of 7, two of eight leg 5, substrate 6, two moving contacting plate combinations 8, two and is formed, as shown in Figure 2.For effectively saving design space in the relay, 11 positions, glass insulator hole that are used to install leg in the substrate 6 are set to staggered and centrosymmetric form, high pressure resistant and the insulation property of this relay so both can have effectively been improved, also reached the purpose that makes full use of its space, in addition, because the width of all reeds is all very little, can make it to contact by the method for applying counter-pressure for movable contact spring 7 with normally closed reed 8, to guarantee the reliability of its contact, so movable contact spring combination 7 and Chang Kai spring combination 9 are arranged on same one side of substrate in combination center line, normally closed reed 8 are arranged on other one side of center line.Leg makes up, often opens between spring combination, the normally closed reed and all adopt soldering to be connected with moving contacting plate.
The electromagnetic mechanism 2 of relay is made up of coil 16, armature combination 17, two yokes 13, support 14, cover plate 15 and two pads 18, as shown in Figure 3.In order rationally to utilize the minimum space of this relay, iron core 12 wherein is designed to rectangular structure, yoke 13 is designed to flat structure, slightly be cuboid after coil 16 coilings like this, make coil 16 guarantee that electromagnetic attraction reaches instructions for use and gets simultaneously, can also more efficient use relay space; Armature adopts the balanced rotary structure, and it unshakable in one's determination 12 all adopts resistance spot welding to be connected with support 14, yoke 13 with cover plate 15 with yoke 13, yoke 13.
When the common relay lead-out wires of coil links with leg, directly with welding again after lead-out wires of coil is on the leg, the utility model is for ease of operation, when being connected with leg 5, adopts lead-out wires of coil 21 special transition lead-in wire 22, i.e. first 5 welding transition lead-in wire 22 on leg refills behind the sleeve pipe and lead-out wires of coil 21 solderless wrapped connections, welding.
