In recent years,the reliability of electronic product safety requirements are increasing, so it must be in the electronic products to install some circuit protection components, this trend prompted circuit protection components of rapid development, the formation of a new growth point in the field of electronic components. The terminal is the most common electronic components, with its extensive use of unique irreplaceable by industry, advantage throughout its value to rise, Elinker summarized as follows:
With the development of electronic products demand, the function of IC (integrated) is more and more strong, the "value" of nature more and more expensive, and therefore the need to strengthen the protection of.
(1) in order to reduce the power consumption, reduce the heat, prolong the service life, working voltage and a semiconductor element and a lower IC, according to SIA (American Semiconductor Industry Association statistics, at present) working voltage is about 1.5V, in 2004 will drop to below 1.2V, the anti current / ability over voltage of the need to adapt to the new protection requirements.
(2) mobile electronic products more and more, such as the handset, PDA, notebook computer, video camera, digital camera, CD machine, these electronic products need batteries as the power supply, the battery module and battery charger must be equipped with protection element.
(3) in the modern luxury cars, more and more electronic equipment, and the working conditions worse than electronic products in general, vary from minute to minute, such as state and environment of vehicle auto starting causes large transient peak voltage etc.. Therefore, in the power adapter for the electronic equipment, generally need to be installed at the same time overcurrent and overvoltage protection element.
(4) many electric / electronic products are required to prevent lightning and power line and telephone line crossing, in order to ensure the normal communication and the personal safety of users. So, with the development of electric / electronic products, over current and overvoltage protection element is rising.
(5) according to the statistics, in the fault of electronic products appear, 75% is the result of over current / voltage caused by. IBM had analyzed the failure causes of computer power, 88.5% of which is due to excessive current / voltage caused by. Along with people demanding on the quality of electronic products, manufacturers in order to enhance the market competitiveness, we must use a large number of circuit protection components.
Terminal classification:
The fence: is able to achieve safety, reliable, effective connection, particularly in the large current, high voltage applied widely use in the environment.
Spring: spring is a new terminal device utilization, has been widely used in the world of electrical and electronic engineering industry: lighting, elevator control, instrumentation, power, chemical and automotive power etc..
The track installation: the reliable thread connection technology, electronic let off and the electrical connection technology, widely used in power electronics, communications, electrical control and power etc..
Track type: the pressing and unique thread self-locking design, which makes the wiring connection is reliable, safe. The series terminals elegant design, can be matched with various accessories, such as short circuit plate, a baffle, identification.
