What is the basic definition of a connector? The most vivid metaphor in history

Connector is a component that we electronic engineers often come into contact with. Its role is very simple: in the circuit is blocked or isolated between the circuit, bridging the communication, so that the current flow, so that the circuit to achieve the intended function.

Connector is an indispensable part of the electronic equipment, along the current flow path, you will always find one or more connectors. Connector form and structure is ever-changing, with the application object, frequency, power, application environment and so on different, there are various forms of connectors.

For example, the connector used to light the lights on the court is very different from the connector used for hard disk drives and the connector used to light rockets. But no matter what kind of connector is used, it is important to ensure a smooth, continuous and reliable flow of current. In terms of generalization, connectors are connected to more than just current.

In today’s rapidly developing optoelectronics, fiber-optic systems, the carrier of the transmitted signal is light, glass and plastic instead of ordinary circuit wires, but the optical signal pathway also uses connectors, which serve the same purpose as circuit connectors.

Connector Definition

A connector is a motor system that provides a separable interface to connect two subelectronic systems and does not have an unacceptable effect on the operation of the system. The key words in the definition are “motor system”, “separable” and “unacceptable effect”. A connector is a motor system because it is electrically connected by mechanical means.

As will be discussed, the mechanical spring deflection creates a force between the two parts of the mating, which makes metallic contact between the mating surfaces of the interface. The reason for applying connectors in the first place is that the mating interface is separable. The need for separability is necessary for many reasons.

It allows parts or subsystems to be manufactured independently and final assembly to take place in one main location. Separability also allows parts or subsystems to be maintained or upgraded without modifying the overall system. Another reason for separability is portability and support for expansion of peripheral devices.

On the other hand, the definition of separability introduces an additional interface between subsystems that must not introduce any “unacceptable effects”, especially in terms of system characteristics that cannot be affected by electrical signals, such as unacceptable distortion and signal degradation between systems, or power loss through connectors.

These effects include unacceptable distortion and signal degradation between systems, or power loss through connectors, which will become a major design criterion for functionality, and therefore an increase in the power requirements of the motherboard.
