Development of magnetic latching relay technology
The rapid development of computer technology, modern communication technology, electronic technology and space technology, put forward new requirements for the development of relay technology, new technology will accelerate the development of the relay technology.
With the rapid development of microelectronic technology and super large scale IC, new requirements have been put forward for relays. The first is miniaturization and flaking. IC packages such as military TO - 5 (8.5 x 8.5 x 7.0mm) relay, it has high anti vibration, can make the device more reliable; the second is the combination and multi functions, compatible with IC, built-in amplifier, require sensitivity to the micro watt level; the third is solid. The solid relay has high sensitivity and can prevent electromagnetic interference and radio frequency interference.
With the popularization of computer technology, the demand for relays for microcomputers is greatly increased, and relays with microprocessors will develop rapidly. In the early 80s, the digital time relay produced in the United States can control relays with instructions, and the combination of relays and microprocessors can form a compact and perfect control system. Computer controlled industrial robots at an annual growth rate of 3.5%, now, the computer control system of production has a production line in a variety of low cost relay, and can automatically complete a variety of operations and tests.
The development of communication technology has far-reaching significance for the development of relay. On the one hand, because of the rapid development of communication technology, the application of the whole relay is increased. On the other hand, because the fiber is the transmission of the information society aorta, in optical fiber communication, optical sensing, optical computer and optical information processing will occur under the impetus of optical relay, reed fiber switch relay model.
Optoelectronic technology will greatly promote the relay technology. In order to achieve the reliable operation of optical computer, a bistable relay has been manufactured.
In order to improve the reliability of aerospace relays, it is expected that the failure rate of relays should be reduced to 0.01PPM by the current 0.1PPM. Manned space stations require 0.001PPM. The temperature resistance should be above 200 DEG C, the vibration resistance requirement is higher than 490m/s, and it should be able to withstand 2.32 x 10 (4) C/Kg alpha ray radiation. In order to meet the requirements of space, we must strengthen the reliability research, and establish a special high reliable production line.
Special structure of new materials, new molecular materials, high-performance composite materials, optoelectronic materials, magnetic materials, and the development of oxygen sensing magnetic materials, amorphous soft magnetic materials are of great significance to the development of a new type of magnetic latching relay, thermal relay, electromagnetic relay, and will the emergence of new principle, new effect relay.
With the development of micro and chip technology. Relay will be two-dimensional and three-dimensional dimensions of only a few millimeters of micro and surface mounting direction; now some international manufacturers of relays, the volume of only 5~10 years ago 1/4 ~ 1/8. Because the electronic unit reduces the volume, it needs a smaller relay that is no higher than other electronic components. Communication equipment manufacturers demand for intensive relay more eagerly, a series of BA FujitsuTakamisawa company of Japan, ultra dense signal relay size is only 14.9 (W) * 7.4 (D) * 9.7 (H) mm, mainly used for fax and modem, can withstand 3kV wave voltage. The company launched the AS series surface mount relay with a volume of only 14 (W) * 9 (D) * 6.5 (H) mm.
In the field of power relay, especially the need for safe and reliable relays, such as high insulation relays. The JV series power relay introduced in Japan consists of five amplifiers, with high insulation, small cross sectional design, size 17.5 (W) * 10 (D) * 12.5 (H) FujitsuTaKamisawa, mm. Due to the use of a strengthened insulation system between the core and the outer edge, the insulation performance is up to 5kV. The power consumption of the MR82 series power relay introduced by NEC in Japan is only 200mW.
In the relay, a variety of circuits such as amplifying, delaying, eliminating contact, dithering, arc extinguishing, remote control and combinational logic are installed in the relay to make it have more functions. With the breakthrough of SOP (SmallOutlinePackage) technology, it is possible for manufacturers to integrate more and more functions together. The combination of relays and microprocessors will have a wide range of specialized control functions, enabling high intelligence.
The emergence of new technologies will promote the development of relays with different principles, different performances, different structures and applications. In the progress of science and technology, and promote the sensitive demand traction and functional materials development, special relays, such as performance, high pressure, high temperature, RF insulation, low thermal emf and non electricity control relay will continue to improve.
Electromagnetic relay (EMR) has been used for more than 150 years from the initial use of the telephone relay. With the development of the electronics industry, especially the breakthrough of the optical coupling technology in the early 1970s, the solid state relay (SSR, also known as electronic relay) has sprung up. Compared with traditional relay, it has many advantages, such as long life, simple structure, light weight and reliable performance. Solid state relays have no mechanical switches, and have important features such as high compatibility with microprocessors, high speed, shock resistance, vibration resistance, and low leakage. At the same time, because the products do not have mechanical contact, no electromagnetic noise is generated, so that components such as resistors and capacitors are not required to keep silent.
Traditional relays require these additional components, so conventional relays are often cumbersome and complex, and cost more.
In the future, small sealed relay focused on market development is compatible with IC TO-5 relays and 1/2 relay lens cover. Military relays will accelerate the transfer to industry / commerce. American military relays account for about 20% of the total relay. The general relay market continues to develop toward small, thin and plastic packaging. Small PCB Relay will still be the mainstream products of universal relay market development, solid state relay will be more extensive, prices will continue to decline, and close to the high reliability, small volume, high anti impact and interference of inrush current. Reed relay market will continue to expand. Surface mount relay applications and demand will show a rising trend
