Electrical connectors drastically reduce the time, effort and manpower needed for manufacturing, assembling and installing electrical devices, their components as well as wiring.
Most connectors have two main parts – the housing, and terminals for making the connections:
For some applications, electrical connectors that possess different features might be required or preferred:
To select the right electrical connectors that will get the job done and minimize risks, there are a few factors which should be considered, depending on the application, type of connectors and the strength of the electrical current the circuit will carry. These can be broken down into two classifications:
Performance parameters need to be selected based on the conditions in which the electrical connector is going to operate:
Physical parameters should be selected carefully, since they describe how the electrical connector is designed, the connections it can be used for and much more:
Zinc content can vary from 5-40%; cheapest metal to purchase by weight; springy; strong; high conductance, used in KK terminals.
Good strength; tough; high conductibility and fatigue resistance; flexible and elastic, used in electrical contact springs.
Best alloy for spring terminals; cheaper than phosphor bronze, used for high-performance applications.
High Copper Alloy
Strong modified copper; good electrical and thermal properties; retains its form at high temperatures, mainly used in automotive applications.
Types of Electrical Connectors
There are many types of individual electrical connectors, which can be categorized by level, function, and type of termination:
