IDC – Insulation Displacement Connector

Insulation Displacement Connector (IDC) is an electrical connector designed to connect the conductors. They work directly with multi-layer magnet wire coatings while maintaining a high normal force and a low contact resistance. Insulation Displacement Connector can also support the validation and testing techniques. Insulation Displacement Connection connectors were designed to support the high-power and harsh environmental applications. Insulation Displacement Connector is mostly used for the transmission of power. This process involves several methods like terminal clamp screwed and soldering contacts. The Insulation Displacement Connector is suitable for the connection of conductors.

What is a Conductor?

Conductor is a metallic device. In conductors, the flow of electrical current is free to move anywhere within the conductor, and the movement of the electrons is also easy to pass through the material.

How is charge particles generated in the conductor?

As we know that electron can move freely in the conductor rod anywhere contained by the conductor which is normally a metallic device. The flow of electrons in the conductor is common so the movement of electrons looks like a flowing ocean. When positive charge particles are brought near the conductor the electrons gets attracted towards the charged rod of the conductor. As the electrons gets attracted to the conductor near the rod an attractive force gets induced between rod and the conductor. Similarly when negative charge particles are brought near the in conductor, the electrons gets repelled away from the charged rod. This causes the force between the rod and conductor. With this we can conclude that the charged particles are always attracting with conductors.

Insulators are in general consisting of solid particles which offer high resistance. The property of resistance is used in the flow of electrical current. Insulator is basically a non metallic device. The materials in the insulator which are practically good are recognized by their resistive nature. The resistive materials are glass, mica, quartz, plastic, rubber etc.

How charge particles will generated in the insulator?

In insulator the flow of electrons are not free to move across the material. They are effectively restricted to move only around the atom to which they are attached to. They are able to move from one side of the atom to other side of atom and those electrons which are attached to the atom can’t be able to leave the atom through which they are attached. So charge particles are staying along with the insulator where we had put them.

Image1Working of Insulation Displacement Connector (IDC):


Modern IDC technology has designed to connect only solid conductors; it was eventually extended to multiple-stranded wire as well. They involve no wire stripping means soldering is not required and have low insertion forces, discrete or multi standard cables can be applied. The application process is very simple and easily controlled. The wire insulation within the final contact area is removed during the insertion process to create a semi permanent metal to metal connection between the wire and the IDC connector. The keys to designing a reliable IDC connection are to generate a sufficient amount of contact area upon insertion of the wire and maintaining sufficient normal force of that contact interface throughout the lifetime of IDC.

Here ribbon cable is designed to be used with multi-contact IDC connectors and many IDC connections can be made at once, saving time in applications where many connections are required. The IDC connectors are not reusable but when the care is taken after removing from the cable then only we can re-use them. The characteristics of the IDC is to prevent the potential damaging of the gas and dust which are initially, insulation displacement connections were seen only in extra-low voltage applications, such as telecommunications, networking and signal connections between parts of an electronic or computer system. And also allows easy way modification for the existence of cable installations. Which are designed for low voltage telecommunication cables. Insulation displacement connector acts as a bus connection in the field of electronic devices. The benefits claimed for their use in these applications include up to 50 percent faster installation, due to the reduction in the stripping, twisting and screwing down processes.

Advantages of Insulation Displacement Connector:

  1. No wire stripping or twisting.
  2. No special tools required.
  3. Provides dependable connections.
  4. Faster installation, minimum clean up.
  5. Easy to handle.
  6. Main advantage of insulation displacement connector is the soldering is not required during wiring.

IDCFeatures of Insulation Displacement Connector:

  1. Designed for low voltage telecommunication cables.
  2. Moisture-resistant sealant protects wires from corrosion.
  3. Use with solid copper single-conductor wire.
  4. Insulation Displacement Connection (IDC) technology for quick, reliable connections.
  5. Field installable with no hand tools needed.
  6. Allows easy modification of existing cable installations.
  7. Insulation Displacement Connection (IDC) technology is a safe connection for conductors.

One of the most common Applications of IDC:

Monitoring and access control system:

The monitor access control is considers as a latest technology which is completely based on the insulation displacement connectors. We can interface monitoring access control through the computer which is useful in adjusting the schedules and are used for billing the data. The main factors which are required for monitoring accessing the outdoor of buildings are humidity , changes in temperature, dust particles, vibrations etc.


Access controlling and monitoring devices plays an important role in the safety purpose of buildings and there surroundings. The main purpose of the access control device is to limit who can able to enter in the building, and also scans about the type of  products should enter in the building, and  the monitoring systems helps in observing how peoples are  going inside the building. Monitoring systems also helps in protecting the building from terrorist attack. Monitoring systems may also helps in giving services as an important tool for investigation of crimes, attacks and other security incidents after they occurs.

The capacity of the monitoring devices such as closed circuit television system which plays an important role in the MAC for giving secure enhancement domain awareness and improve their ability to detect suspicious activity. In introduction CCTV cameras at outdoors of the buildings, systems installers at middle and elevated level buildings should avoid blind spots and make use of appropriate lighting to make certain clear visibility. To avoid a “disaster” of the image until excess light is dimmed or detached, systems installers should search for to reduce the direct introduction of CCTV camera lenses to light.
