A Connector is...
Parts that connect electricity used in electronic devices and components.
For example, it connects one piece of equipment to another, or a module to a board in the equipment to conduct electricity.
Functions of a Connector
- Improve productivity
After each board (unit) is produced in a separate process, connection by connectors in the final process can improve production efficiency.
- Repairable and replaceable
Even if devices or parts break down, they can be repaired with limited replacement.
Modules with connectors can be easily replaced and upgraded.
Types of Connectors
There are two main types of connectors. Connectors, which are mechanical parts in addition to their function connecting electricity, vary in shape depending on what is connected.
Connectors for External Connections: Connections Between Devices
Modular connectors, power connectors, card connectors, etc.
Internal Connectors: Wiring Inside the Device or Connecting to the Unit
Board to board connectors, FPC/FFC connectors, card edge connectors, shield connectors, wire to wire/board connectors, etc.
(de jure standard)
|Products that conform to all dimensions and product specifications set by a standardizing body.|
(de facto standard)
|Products that have been widely adopted because of competition in the market rather than a standard set by a standardizing body.|
|Original Products||General-purpose products developed by each company.|
|Customized Products||Customer-specific products that meet customer specifications.|
Side Story -The History of Kyocera's Connector-
Kyocera's connector business began in 1947 with the hermaphroditic contact concept, which was invented by Benjamin Fox, founder of Elco International Corporation*.
The hermaphroditic contact concept revolutionized connectors with a new structure in which a pair of fork-shaped contacts fit in a cross shape and touched on four sides, enabling the creation of a smooth fitting surface and a large wiping action surface. This mechanism solved problems caused by electrical interruptions, vibration and shock, and significantly improved contact reliability, which is paramount to connectors.
Since then, it has been widely adopted in equipment where reliability is important, such as the world's leading computer manufacturers and airplanes. The reliability of the new standard, MIL-C -28731, has been demonstrated by American MIL for this product.
*Elco International Corporation ... The predecessor of Kyocera Connector Products Co., Ltd. (formerly Kyocera Elco Corporation), which handled connector products before the merger of the Kyocera Electronic Components Division.
