Common Types of Automotive Connectors

As automobiles of all types become increasingly electric, they require more connectors for the means of routing signals through their electrical systems. With the introduction of microprocessor controlled systems, automobiles have begun to take advantage of reliable wiring and electrical connectors, those of which handle any power, data, or audiovisual transfer. As finding automotive connectors with the right current rating, circuit density, voltage, configuration, and bonding force is essential for proper operations, we will discuss the most common fundamentals and connector types to be aware of.

Automotive connectors often fall under the ISO standard 10487, and they can be broken up into four groups. The first set consists of power connectors that allow the main audio unit to function, attaching it to any switches, volume controls, power supplies, and antennas. With the second group of electrical connectors, the speakers are connected to other devices. The third group is considered somewhat redundant, and they handle all connections for remote controls, CD holders, and external amplifiers. The final group handles satellite navigation systems, those of which can be found in many new cars. While these are the four main groups, one may find additional connectors that are attached to sensors, powered windows, radio receivers, relays, lighting, and the ignition system.

With a general understanding of how automotive connectors are used, it is then important to have awareness of the particular connector types that may be found. Crimp connectors are very common and versatile, coming in a variety of sizes to accommodate different needs. Such connectors come in five subtypes, those of which are seamless, seam type, non-insulated, insulated, and heat shrink insulated electrical connectors. The choice between each will generally depend on the needs of a particular system, and it is important to find out what your particular application requires before making a purchase. For example, while heat shrink insulated electrical connectors are considered to be the best choice for automotive applications, they are the most expensive. As they are waterproof, they are often implemented underneath the hood of a car. True to their name, these connectors feature a crimp connection that is solderless.

The next major group of automotive connectors includes mating types, and these are most commonly found within ignition boxes and amplifiers. Similar to crimp connectors, these products come in a number of sizes and lengths to meet varying needs. Connectors and plugs are regularly found in automobile assemblies, ensuring rapid assembly and disassembly when servicing is being carried out. These connectors are most often found alongside dashboards and consoles which can be disassembled as needed. For high-current applications, AWG Wire 8 products are the best with their ample reliability. With such wiring, same sex connectors are presented at each end so that current can only pass in a single direction to mitigate any chance of error. Additionally, with their larger size options and capabilities, AWG wires like these are often used to connect race car batteries and chargers.
