The electrical relay with microprocessor will be developed rapidly

Microelectronic technology, electronic computer technology, modern communication technique, mere electron technology and technical development at full speed of space, having put forward the new requirement to the electrical relay technology, innovative technology, new technical development undoubtedly play a role in promoting to the technical development of the electrical relay.

Microelectronic technology and super large-scale IC development get the new requirement out of too electrical relay at full speed. The first is miniaturization and laminarization. Military TO as IC capsulates- 5(8.5* 8.5* 7.0mm) Electrical relay, it has very high antivibration, can make the apparatus more reliable; The second is unitized and multi-functional, IC -compatible, very built-in amplifier, require the degree of sensitivity to raise to the little watt level; The third is the whole solidification. The high sensitivity of the solid state relay, but anti electromagnet interference and radio frequency disturbance.

The technical popularization of the computer makes the computer increase notably with the demand for the electrical relay, the electrical relay with microprocessor will be developed rapidly. At the beginning of the eighties, the digital time relay which U.S.A. produced can control the electrical relay with the order, the combination with microprocessor of the electrical relay is developed, can form a small and exquisite and complete control system. Increased at the speed of 3.5% for every year at present by the computer-controlled industrial robot, now, the computer-controlled production system can already produce many kinds of low-cost electrical relays on a production line, and can finish many kinds of operation and test job automatically.

The technical development of the communication is far-reaching for development of the electrical relay. On one hand because the technical rapid development of the communication makes the application of the whole electrical relay increase. On the other hand, because the optic fibre will be a transmissive aorta of information-intensive society in future, new electrical relays such as the electrical relay of optic fibre, optic fibre switch of reed pipe of tongue,etc. will appear under optical-fibre communications, only sensory, optical computer, technical push of optical processing.

Mere electron technology will produce huge facilitation to the electrical relay technology, in order to realize the reliability service of the optical computer, has already produced the bistable relay at present.

In order to improve the reliability of aviation, spaceflight electrical relay, expect the failure rate of the electrical relay to be dropped to 0.01PPM from present 0.1PPM; The manned space station demands to reach 0.001PPM. Refractory to want, reach over 200 ℃, require higher than 490m/s while being vibration-resistant, should be able to bear 2.32* 10(4) at the same time Alpha ray radiation of C/Kg. In order to satisfy space requirement, must strengthen reliability to study and and set up specialized high-reliability production line.

New special construction material, new molecule material, high-performance composite material, mere electronic material, there is magnetic material of oxygen intake, the development of the magnetic material of temperature sensing, amorphous soft magnetic material has important meanings in developing new magnetic latching relay, temperature relays, electromagnetic relays, and will present the electrical relay of new principle, new effect.

With miniature and chip type technical improvement. Until millimetre of miniature surface mounted directions of taking develop only to two-dimentional three-dimensional size electrical relay; The electrical relay which some producers produce in the world now, the volume has 1/4- 1/8 5- 10 years ago only. While reducing the volume, need not highly exceeding the smaller electrical relay of the other electron component because of the electronic complete machine. The demand for the intensive electrical relay of communication apparatus producer is more earnest, one the intersection of BA and the intersection of series and ultra intensive magnitude of signal relay that Company produce, FujitsuTakamisawa of Japan, have 14.9(W) only *7.4(D) *9.7(H) Mm, are used mainly in facsimile machine and modem, can bear the fluctuation voltage of 3kV. The volume of AS series surface mounting electrical relay which this company introduces is only 14(W) *9(D) *6.5(H) mm.

Especially need safe and reliable electrical relay in the field of power relay, such as the high insulating quality electrical relay.

The JV series power relay which Japan FujitsuTaKamisawa introduces includes five amplifiers, adopt the small bore of high insulating quality to be designed, the size is 17.5(W) *10(D) *12.5(H) mm. Because adopt the insulation system of ruggedization between inner works and outer fringe, its insulating property reaches 5kV. The power consumption of MR82 series power relay which Japan NEC introduces has 200mW only.

While packing within the electrical relay into various and enlarging, prolonging, disappearing in circuit such as contact shaking, arc extinction, remote control, combinatorial logic can make it have more functions. With SOP technology (SmallOutlinePackage) Break-through,manufacturer increasingly many function is integrated to probably. And the combination with microprocessor of electrical relay will possess more extensive special control function, thus realize high intellectuality.

The new technical emergence in groups, will promote different principle, different characteristic, different structure and all kinds of electrical relays of the use to competitively develop. Draw in scientific and technological progress, demand and under the push of sensitivity, functional material development, special electrical relay, for instance temperature, radio frequency, high pressure, high insulating, low thermoelectric force and non electrical quantity are controlled,etc. the characteristic of the electrical relay will be becoming better and approaching perfection day by day.

Electromagnetic relay (EMR) Since using the telephone relay to calculate at first, have already had a history of more than 150 years so far. With the development of electronics industry, especially the technical break-through of initial optical coupling of the seventies of the 20th century, enable the solid state relay (SSR, also calls the electronic relay) A dark horse. Compared with traditional electrical relay, it has advantages such as longe-lived, light, reliable performance simple in construction,etc.. The solid state relay does not have mechanical switch, and have important characteristics, such as compatible with microprocessor height, fast, impact-resistance, vibration-resistant, low leakage,etc.. Meanwhile, because this kind of product does not have mechanical joint, do not produce the electromagnetic noise, thus does not need to add for example the resistance keeps squelch muting with components such as the electric capacity,etc.. But the traditional electrical relay needs these add onses, so, the traditional electrical relay is often cumbersome and complicated, and cost great.

In the future, the focal point of market development of the small-scale sealed electrical relay is and IC compatible TO- 5 electrical relay and 1
