Intelligent, communicative, easy to install and globally applicable, these are just some of the other requirements of plug connections, because they must increasingly meet the requirements of the Industry 4.0 are equivalent to. The electrical plug connection of today is therefore definitely a high-tech component!

Who invented the connector?

The exact invention of the connector can not a single person or assigned to a specific date, as it has evolved over the years out of the need to be able to make and break an electrical connection easily and safely. Rather, it is an evolutionary development based on the growing technological and industrial demands of the time. The development of connectors can be divided into different phases:

  • Early Beginnings: As early as the late 19th and early 20th centuries, the introduction of electricity into homes and businesses created a need for reliable and safe methods of powering electrical equipment. This led to the development of the first simple plug-in connections.
  • Telecommunications: With the expansion of the telephone network in the 20th century, the need for connectors increased significantly. This led to the development of specialized connectors for telecommunications.
  • military and aviation: In the 1930s and 1940s, military and aerospace requirements led to the development of robust and reliable connectors that needed to perform in harsh environments.
  • electronics revolution: With the advent of the electronics industry in the 1960s and 1970s, there was a tremendous need for smaller, more accurate, and more reliable connectors, leading to an explosion in connector variety and technology.

What is included in electrical connection technology?

Electrical connection technology includes a variety of components and methods used to make electrical contacts and ensure that electrical currents or signals are safely transmitted from one point to another. Here are the essential elements of electrical connection technology:

  • junction boxes and junction boxes serve as central connection points for several cables or lines, especially in buildings or systems.
  • insulators are materials or devices that prevent electrical contact between conductors to prevent short circuits or unwanted current paths.
  • jam such as screw terminals, spring terminals and pin terminals, are used in control cabinets or on printed circuit boards to connect wires and cables.
  • Shrink is a method in which the wire and connector are mechanically pressed together to create a strong and reliable connection.
  • PCBs (PCBs) are used to support electronic components and to electrically connect them together using copper traces created by etching processes.
  • solder joints: Here, two metallic parts are joined together by melting an additional metal or alloy, the solder.
  • Terminals serve as end pieces for electrical conductors to connect them to connection elements such as terminals or screw connections. 
  • Cables and Lines serve as a transmission medium for electrical energy or signals over long distances.
  • Relais and Sagittarius are used to switch larger currents with the help of a smaller control signal.
  • Protection- and grounding components include surge protectors, grounding strips, and other items that ensure electrical systems operate safely and within specified limits.
  • Switch and Button are components that can start or stop the flow of electricity.
  • Connectors are mostly modular units that make it possible to connect and disconnect two or more cables, circuit boards or devices.
