Buying Guide

The market is flooded with a variety of automotive electrical connectors for automobiles. These connectors differ in shape and pin configuration.

Choosing a suitable connector for cars is a bit tricky. The following factors will make it easy for you to select the right connector for your needs.

Copper Plating

Copper is the most efficient conducting material. Some connectors are even provided with high precision copper that ensures that the connector does not fail and has a longer life.

It also effectively saves the connector from short circuiting. You must always check for the contact material of the connector.

Waterproof

Waterproofing of electrical conductors is one the most important factors to consider while buying a suitable connector for your needs. The connectors are often made of plastic or nylon material. Both of these materials offer very good resistance to water.

Some connectors are even provided with a rubber silicone seal that fully protects the terminal and does not allow the water and dust to enter the connector. The waterproof also protects the connector from short circuiting.

Tight grip

The grip of the wires in the connectors is also of utmost importance. If a wire slips out of the connector, it will cause problems for the electrical wiring system.

The new connectors come with a built-in buckle that tightly holds the wires inside the connector and prevents slipping of the wires.

Cable Identification

Cable identification makes it easier for you to trace and locate the wire quickly during the maintenance of the electrical faults of automobiles.

Some connectors have wire gauge imprinted on them while some have color coding for identification of wire gauge. It is a very useful factor to consider while buying the right connector for your needs.

Installation

The installation of wires in the connector is the key to the success of the connector. For most of the connectors, soldering or crimping is used to strengthen the wire connections.

The terminals of some of the connectors are heated with heat to strengthen the connector. Some connectors are even having a push-in option to install the wire.

Always check the installation module before purchasing a suitable connector for your needs.

Compliance with Safety Standards

The wire connectors are directly related to the electricity and it is important to have safe, reliable, and long lasting connectors. Any bad-quality connector can cause a serious human injury.

Always check for the conformance of the connectors with ROHS, ISO 9001-2008, SGS & CE Standard.

Frequently Asked Questions (FAQ)

The following frequent questions will also be helpful and make it easier for you to choose the right and best suited electrical connector for your automobile’s needs.

What are the Automotive Waterproof Wire Connectors?

Here is a list of top rated connectors as per my ratings;

  1. Qibaok Waterproof Automotive Wire Connectors
  2. Sopoby Heat Shrink Waterproof Automotive Wire connectors
  3. Twipo Waterproof Automotive Electrical Connectors
  4. OCR Waterproof Automotive Electrical Connectors
  5. Hifrom waterproof electrical connectors
  6. Glarks Waterproof Electrical Connectors
  7. Kuject Waterproof Automotive Electrical Connectors
  8. Yetor Waterproof Automotive Electrical Connectors
  9. Nilight Quick T Tape Wire Terminals
  10. Muyi Waterproof Electrical Connectors

Are the automotive wire connectors waterproof?

Yes, the automotive wire connectors are made of plastic or nylon that are highly resistant to water. The connectors are further provided with a rubber silicone seal that enhances the waterproof ability of the wire connectors.

How are the connectors installed?

The connectors are very easy to install. The wires are connecting while soldering & crimping the connectors.

Is Crimping needed to use a solder seal connector?

Not, the connector which has the solder ring does not require crimping. The cable is inserted in the connector and twisted to enhance the grip of the wire. This kind of connector has transparent tubing that clearly shows the wires inside the connector.

What is the heat shrink ratio and why is it considered?

The heat shrink ratio tells about the shrinking of the tubing of the connector. For example, 4:1 heat shrink ratio means that the connector will be four times the size of shrink tubing. It is considered for compatibility and installation of wires.

Is the polyolefin tubing a better choice for connecting wire?

The polyolefin tubing is the heat shrink. The heat shrink tubing is used because during the connection of wire the tubes are heated to secure the wires. The polyolefin tubing is flame retardant and best suited for the automotive electrical system. These are so popular that they are also called automotive tubing.
