Tungsten copper contact
for electronic has excellent wear and corrosion resistance and mainly used for
controlling electron motion in vacuum, air or solid. So it has a wide range of
application, such as electronic components, connectors, semiconductor discrete
devices, electro-acoustic devices, laser devices, electronic display devices,
optoelectronic devices, sensors, power supplies, switches and other electronic
chemical materials and parts.
1. Wedge-type
Contact: By the use of double-headed bolt sets of spring pressure in the
conductive seat on the pairs of contact and wedge-shaped contact block
composition, the general wedge-shaped contact block as a moving contact. When
the moving contact is contacting with the static contact, the contact surface
will be cleaned by the friction. Its high electric stability, self-cleaning
effect, increase the number of contacts and wedges may increase the rated
current, but also increased the size of the horizontal, so the assembly is difficult;
2. Insert-type Contact:
Static contact is composed of multiple trapezoidal fingers. There are two types
of flexible conductive sheet and non-flexible conductive sheet. A flexible
conductive piece of the socket, a finger on the groove, groove embedded in the
insulating sleeve, into the coil spring, in order to ensure that the finger on
the conductive rod pressure, the other end of the spring ring support, along
the conductive rod (moving contact) around to adjust the touch finger position slightly.
China's electronic
components production has accounted for more than 39% of the world. The major
products include capacitors, resistors, electro-acoustic devices, magnetic
materials, piezoelectric quartz crystal, micro-motor, electronic transformers,
printed circuit boards. So tungsten copper contact for electronic also has a
lot of the demands. With
the expanding scale of China's electronic information industry, the Pearl River
Delta, Yangtze River Delta, the Bohai Bay region, part of the central and
western regions of the four major electronic information industry base
initially formed. These
areas of electronic information enterprise concentration, the industry chain is
more complete, with considerable size and supporting capacity. However, there
are some problems in electronic components industry, such as excess low-end
products, and high-end products mainly rely on imports; lack of core
technology, low product profits; inadequate investment for technology
development.
