Types of Connectors

Types of Connectors

Various types of connectors are used to perform one particular function that is to connect or disconnect the circular path of the electric current. Depending upon the various function of connectors such as design and durability, ease of connection, mating type, insulation between pins etc., it is designed to perform in extreme conditions such as prevention from dirt, water, contaminants, extreme temperatures and vibrations etc.

Connectors are classified into various types based on function, level and type of termination.

Classification of connectors based on connector level:

  • Box-to-box or input/output
  • Wire-to-board
  • Chip-to-package
  • Package-to-board
  • PC board-to-board

Classification of connectors based on connector function:

  • Terminal Block
  • Binding Post
  • Plug and socket
  • Rack and Panel
  • Blade
  • Ring and Spade

Classification of connectors based on connector termination:

  • Insulation Displacement
  • Crimping

Terminal Block

In this, more than one wire are connected to one terminal. It is used in housing and lack of protection makes it inefficient with comparison to others. Its connection is also categorized as

  • Printed circuit board terminal blocks (PCB)
  • Pluggable terminal blocks
  • Multiple terminal connectors (MTC)
  • Barrier Strips

Binding Post

These type are used in various audio and electronic testing devices. In these, bare wires are connected to a post which are fastened with screws and the opposite end it connected to terminals, plugs and pins.

Plug and Socket

Here one plug is connected to one or many pins. These makes connections easy and uses no tools. It used in many electronics for handling audio and video such as USB, HDMI, network, computing etc.

Rack and Panel

This connects electronic parts which can be removed with stationary equipments, where space and connection’s reliability is matters. It has 3 types namely:

  • Rack and panel
  • Cable to cable
  • Cable to panel

These are used in appliances like home stereo systems, modems, printers etc

Blade

This connects single wires to blade receptacles using conductive blades which are flat. These are attached to connecting wires and are used in thermostats and speakers.

Ring and Spade

Here, the connection is sandwiched between a screw and a threaded post. It enables easy connections which can be removed because the lock is partially closed.

Insulation Displacement Connectors (IDC)

This connects insulated wire and does not uses any pre-stripping of insulation. When electrical insulators are inserted, a series of blades cuts the insulation. These helps to lower the current handling capabilities.

Crimping

These creates a connection between connectors and wires which can be separated later. These are ideal for safety, easy-to-use, cost-effectiveness
