Ultimate Guide to Insulation Piercing Connectors: Features, Benefits, and Applications
Insulation piercing connectors are electrical connectors that utilize a joining process to pierce or replace the insulation of a wire or cable to form a conductive path to the internal conductors. They are also commonly referred to as Insulation Piercing Clips, Insulation Replacement Connectors, and Wire Tap Connectors. The use of insulation piercing connectors eliminates the need to strip the insulation from the conductors before making the connection. Below we will describe the common types and provide the advantages and disadvantages of using such insulation piercing connectors.
What are Insulation Piercing Connectors?
Insulation piercing connectors are specifically designed to quickly diagnose, test, or connect wires in circuits with a minimum of hassle, and are used in areas where terminal connections are difficult to reach or where disconnections are not appropriate. Available in a variety of sizes, contact types, and connection forms, their use during electrical testing is fast, efficient, and reliable as it does not involve any stripping or twisting of wires. Quick installation and minimal cleanup, as well as reliable performance, have made Insulated Puncture Connectors popular in many industries. Examples of electrical test applications include vehicle wiring harnesses, electronic locks, alarms, and network and telecom cables. These low-voltage circuits are ideal for insulation piercing connectors.

Performance and Reliability of Insulation Piercing Connectors
Connectors utilizing Insulation Piercing technology are designed to create a semi-permanent metal-to-metal connection between the wire and the Insulation Piercing connector. Several factors can affect its performance and the reliability of the connection. These factors include:
- The type of contact
- Connection method
- Connector tip design
The type of contact
Connection reliability has a direct impact on the performance of a connector where the insulation is pierced during electrical testing. The most commonly used contacts consist of a single pin or a group of multiple pins, often referred to as a “bed of nails”. The number or size of these pins piercing the insulation directly affects the quality of the connection.
The right type of contact for your application is critical. Too small and the needles will have difficulty breaking through the insulation, making the connection weak or intermittent and producing misleading results. Too large and the hole created by the needle will not repair itself and will likely damage the conductor due to corrosion or dirt bypassing the insulation. The bed of nails contact type is often preferred for smaller gauge cables because a single pin can easily miss the internal conductor. Bed of nails increases the reliability of establishing a positive connection
Connection Method
Another important factor affecting the reliability of Insulation piercing clips is the method of connection. Sufficient force to hold the contact interface in place is essential to ensure a strong and reliable connection for electrical testing. Connection methods are generally suitable for different applications and available methods include screw-in, spring-loaded, and hand force. Some methods will combine both to maximize the likelihood of a good first-time connection. Below we will look at the different methods and explain their advantages and disadvantages.
Screw-in connections
Screw-in insulation piercing clips are slower to install than both spring-loaded and hand-piercing connectors. This is even though this type of connection is stronger and more reliable over a longer period of electrical testing. However, reasonable access to the wires is required to ensure that the technician can tighten the piercing connector for a good connection.
Advantages:
- Hands-free testing
- Personal assurance that connectors are tight
- Very reliable connection
- Strong
Disadvantages:
- Slow to install
- Excessive pressure may damage the internal wire harness
- Limited to applications where wires are accessible enough and screwable connections can be made.
Spring Connection
Insulated Puncture Connectors with spring connections rely on the tension of a spring to insert a pin into the insulation to make contact. A spring is an elastic object that stores mechanical energy. The energy of the spring depends on the size, material, and number of coils. The handheld nature of these probes typically limits the maximum voltage capacity.
Advantages:
- Reliable connection
- Fast connection
- Cost-effective
Disadvantages:
- Shorter service life because the spring eventually wears out, resulting in a weaker connection
- Weak springs can make it difficult to pierce the hardened insulation that is often found on old wires, which harden with heat
Connector tip design
The tip of an insulation piercing connector has a shape designed to help locate the connected wires. This usually takes the form of a “V” or “U” shape, with a radius that fits so that the wire the connector is designed for is centered underneath the tip. It is also possible to find tips with extended hooks, which are embedded in the needle to capture the wire in the jaws.
It is important to select an Insulation piercing connector that fits the range of wire diameters you want to use. Ideally, the wire is centered on the tip so that the needle can pierce the wire right in the middle. If the tip is too large for a small diameter wire, the wire may not be positioned correctly in the tip and the needle may miss the conductor or make a poor connection. If the connector tip is too small for a large diameter wire, the pin may push the insulation aside and miss the conductor again. This is especially important if it is difficult to see the connection point when making the connection.
The “V” shaped tip has the greatest adaptability to a wider range of wires and the technician can assist in the connection process by gently pulling the connector over the wire to help center it at the bottom of the “V”.
Conclusion: Insulation Puncture Connectors
Insulation piercing connectors are useful in many applications, the most common being automotive diagnostics, telecommunications, security alarms, and decoders. Many specialized connectors on the market use different contact types, sizes connection types, and different tip designs to help locate wires. To select the right Insulated Puncture Connector for your application, it is recommended to use a “work backward” approach and evaluate the wires you plan to test. Then, determine your exact Insulation Puncture Connector requirements based on wire diameter capability, contact type, and connection method. There are many electrical strain relief connectors for different applications, but using the right tools often makes the task faster, safer, and more accurate.
