Micro Connectors Are Widely Used
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, 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, Miniature Connectors each pin is equipped with a steps, the step is supported on the upper surface of the circuit board, two steps and the tail of the terminal together to form a positioning surface, so that the micro-connector on the host plate positioning solid and reliable.
The development of miniature connectors
The miniaturization of connectors is developed by the miniaturized military electronic equipment. Miniature Connectors 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, micro-connector development has reached a new stage. 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 most demand for miniature connectors. In the next decade, laptops and Handheld PCs will become mainstream PCs, and a portable laptop requires a lot of different types of micro-connectors including the components of a substrate, the board of a substrate, subsystem one child system, substrate -1/o end, such as interconnect products such as IC sockets, FPC, PBC, D and other types of connectors, the vast majority of these products belong to the Space 1. Miniature 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, Miniature Connectors applications will be more and more extensive.
On the military front, as the international situation changes and the military connector market shrinks, the demand for micro-connectors may slow down, but adapting to the harsh use environment and high reliability requirements of military electronic equipment is the main driving force behind the development of micro-connector technology, high-grade miniature connector products are often used in aviation, modern military electronic equipment and new weapons and other sophisticated military equipment, can be predicted that in the coming 21st century, modern military equipment is still a miniature connector research and development , one of the important fields of application.
