Micro-connectors Have The Characteristics Of Electromagnetic Interference
The miniature connector is used for the connection between the mouse, keyboard and other input devices and the host, including insulating body, shielding shell and several terminals. wherein, the insulating body has a plurality of plug holes which can be plugged into and the socket holes of the terminals which are connected by the plug hole, the head of the terminal is accommodated in the terminal receiving hole, Miniature Connectors and the rear surface of the insulator is stretched out and welded to the printed circuit board, and the cylindrical shielding shell is coated on the periphery of the insulating body. The shielding shell at the bottom of the left and right side of each has a pin, each pin is equipped with a step part, the step support in the upper surface of the circuit board, two steps and terminals of the tail together constitute a positioning surface, Miniature Connectors so that the micro-connector on the motherboard on the location of solid and reliable.
The miniature connectors include the base, the cover and the inserts, the micro-connector is a base combined with a cover piece as the mother end, so that the insertion of the base and the cover between the insert as the public end, in the base electrically connected to the end of the insertion of the terminal using plasma processing technology to control the shape, with low voltage to generate power, Miniature Connectors Reduces the overall size while narrowing the terminal spacing, providing low insertion force, low electrostatic force and fixing the insert, the invention also has the characteristics of holding function, resisting electromagnetic interference, Miniature Connectors adjusting terminal impedance, reducing manufacturing cost, saving test time and cost, and has repetitive working ability, which improves the design flexibility.
The development of miniature connectors
The miniaturization of connectors is developed by the miniaturized military electronic equipment. As early as the World War II, the United States used the center distance of 2.54mm non-sealed rectangular connectors for military installations. The connector's micro-form was developed rapidly in the 670 's, with a center distance of 2.54mm connector is a common product, in the individual military occasions have even reached 0. $number mm. At that time, the development of micro-connectors has been very high level.
In recent years, the rapid development of electronic technology, product upgrading, portable products increasingly popular, and greatly promote the development of a micro-connector, Miniature Connectors micro-connector development has reached a new stage. Spacing 1.27mm Connector technology is basically mature. The average product spacing has also reached 1.0mm~0.8mm level. 0.3mm Ultra Miniature FPC connector products have been present. As a whole, the size and weight of the connectors are also falling significantly. For example, the Molex 890 series D socket used in I/O is 40% less than the traditional model. The B802 connector product produced by French manufacturers weighs only 1g.
Market conditions of miniature connectors
The application of micro-connectors is very extensive, from the computer, communication equipment to industrial testing equipment, from military equipment to new electronic consumer goods and so on, Miniature Connectors the micro-connector products to different degrees of demand.
Laptops have the greatest demand for miniature connectors. In the next decade, laptops, handheld computers will become mainstream PC, a portable notebook computer requires a large number of different types of micro-connectors, including the components of a substrate, the board of a substrate, Miniature Connectors subsystem one-child system, the substrate -1/o end and other interconnect products such as IC sockets, FPC, PBC, D and other types of connectors, The vast majority of these products belong to 1. Micro Products below 27mm
Communication equipment with connectors also in the direction of miniaturization, the application to the micro-connector mainframe is pagers, mobile phones and so on. Modern communication technology is changing rapidly, believe that micro-connectors in the new communications technology, applications will be more and more extensive.
On the military side, due to the changes in the international situation, the market for military connectors is shrinking and the demand for micro-connectors may slow down, Miniature Connectors but adapting to the harsh use environment and high reliability requirements of military electronic devices is the main driving force behind the development of micro-connector technology, Miniature Connectors which is often the product of high-end micro-connectors in aviation, Modern military electronic equipment and new weapons and other sophisticated military equipment on the first use, you can predict that in the coming 21st century, the modern military equipment is still a miniature connector research and development, the application of one of the important areas.
