How to choose the best wire connectors for automotive

What is wire connectors for automotive

Automotive electrical connectors or wire connectors for automotive are designed for use in automobile electrical systems. Modern automobile systems are heavily wired and controlled by microprocessors.

This has raised demand for high-quality wiring and connectors. Choose automobile electrical connectors for your car by considering current rating, circuit density, wire size and voltage.

Benefits of best wire connectors for automotive

A diversity of purchasing options

Because the popular car connector is widely used. As a result, it also offers a lot of convenience in terms of purchasing channels.

We can discover equivalent automobile connections products in various retail malls or auto parts city. And the range of connectors will be increasingly diverse as long as there is a car connector for sale. A range of methods for purchasing car connections is also advantageous.

The interface is modifiable.

Reputable automotive connectors provide a relatively well-matched interface, therefore the purchased car connector may have multiple interfaces. You can specify the number of interfaces to which the device should be connected.

As a result, the automotive connector interfaces can be adjusted, and the number of interfaces is optional to satisfy the connection needs of various interfaces.

The interface’s installation is simple.

The car connector has the advantage of having a simple interface. You only need to connect the two devices’ interfaces with the connection.

As a result, the use of automobile connections is simpler than that of other connected devices. It is capable of connecting devices to each other, but the number of interfaces must be considered. Furthermore, there is no requirement to comprehend the wiring topology within the connector. Even though there is no line basis, it is possible to use it directly.

Automotive connectors that are commonly used

Automotive connector products that are commonly used to connect various automotive internal and external devices. Used to add, remove, and replace equipment.

The goal of connecting

The popular automobile connector with auto parts city can be customized and installed by themselves. It is capable of accomplishing the goal of connecting the automotive equipment with each other on a do-it-yourself basis.

Factor to consider before buying bet wire connectors for automotive

Currently Rated

The amount of current (measured in amps) that can be passed through a mating terminal is referred to as its current rating. Check that the current rating of your connector corresponds to the current-carrying capability of the individual terminals being connected.

It should be noted that the current rating presupposes that all of the housing’s circuits are carrying the rated maximum current. The current rating also presumes the use of the maximum wire gauge for that connection family. For instance, if a standard connector family has a maximum current rating of 12 amps/circuit, 14 AWG wire is presumed to be used. When using a smaller wire, the maximum current carrying capability should be reduced by 1.0 to 1.5 amps per circuit for each AWG gauge range less than the maximum.

Circuit Density and Connector Size

The desire to reduce equipment footprint without sacrificing current capacity is driving an increase in the size of electrical connectors. Consider how much room your electrical connections and connectors will require. Connections in vehicles, trucks, and transportable equipment are frequently made in compact compartments with limited room.

Circuit density is the number of circuits that can be accommodated by an electrical connector per 30158 square inch. A connector with a high circuit density can reduce the need for many connectors while also saving space and increasing efficiency. Aptiv HES (Hard Environment Series) connectors, for example, provide high current capability as well as high circuit density (up to 47 circuits) in tiny housings. And Molex manufactures the Mizu-P25 multi-pin connector system, which has a very small 2.5mm pitch and can fit into very small compartments.

On the other hand, there may be times when a 2- or 3-circuit connector is preferable for simplicity and ease of identification. It’s also worth noting that high circuit density has a cost: a potential loss in current rating due to the increased heat created by several terminals inside the housing. A connection that can transport up to 12 amps per circuit in a 2- or 3-circuit housing can only carry 7.5 amps per circuit in a 12- or 15-circuit enclosure.

Materials and Plating for Housing and Terminals

The majority of electrical connectors are composed of nylon plastic and have flammability standards of UL94V-2 or 94V-0. The 94V-0 grade implies that the nylon will extinguish itself (in the event of a fire) faster than the 94V-2 nylon. A 94V-0 rating denotes a better resistance to flame continuation rather than a higher operating temperature rating. The 94V-2 material is suitable for the majority of applications.

Tin, tin/lead, and gold are the most common terminal plating alternatives for most connectors. Tin and tin/lead are suitable for most applications with currents more than 0.5A per circuit. In signal or low-current harsh environment applications, gold-plated terminals, such as those available in the Deutsch DTP compliant Amphenol ATP SeriesTM Connector line, should be specified.

Brass or phosphor bronze are the materials used for terminal bases. The usual material is brass, which provides a superb combination of strength and current-carrying qualities. Phosphor bronze is indicated when a smaller base material is required to provide a lower engagement force, high engagement/disengagement cycles (>100 cycles) are expected, or prolonged exposure to high ambient temperatures (>85°F/29°C) is expected.

Force of Engagement

The effort necessary to join, mate, or engage the two populated electrical connection halves is referred to as engagement force. Total engagement forces for some connection families in high circuit count applications can be 50 pounds or greater, which may be regarded excessive by some assembly operators or in applications where the electrical connectors are difficult to reach. In heavy-duty applications, on the other hand, a high engagement force may be preferred to ensure that the connection can resist frequent jostling and vibrations in the field. 38630

Type of Housing Lock

Connectors are available with either a positive or passive locking mechanism. The degree of stress to which the mated electrical connectors will be subjected determines which type to choose. A positive lock connector needs the user to deactivate a locking device before the connector halves can be separated, whereas a passive locking system allows the connector halves to disengage by simply pulling the two parts apart with a moderate amount of force. Positive locking connectors38854 should be specified in high-vibration applications or when the wire or cable is subjected to axial loads.

As seen here: At the upper right is an Aptiv Apex Sealed Connector housing with a positive-locking connector position assurance tab (in red). The red tab is pushed in to help establish the connection when mating the connector.

Wire Gauge

Wire size is significant when selecting connections, especially when the needed current rating is close to the maximum for the chosen connector family or mechanical strength in the wire is required. A thicker wire gauge should be used in both circumstances. Most electrical connectors can accept automobile wire gauges ranging from 16 to 22 AWG. Refer to our handy wire sizing chart for assistance in determining wiring size and length.

Voltage of Operation

The majority of automotive DC applications are 12 to 48 volts, whereas AC applications can range from 37858 a 600 to 1000 volts. Higher-voltage applications will often necessitate larger connectors capable of containing the energy and heat generated during use.

Listings or permissions from agencies

Ascertain that the electrical connector system has been tested in accordance with the specifications of other connector systems. The majority of connections meet the criteria of the UL, SAE, and CSA agencies. IP (intrusion protection) ratings and salt spray tests indicate the connector’s resistance to moisture and pollutants. See our Guide on IP Codes for Vehicle Electrical Components for more information.

Environmental Aspects

When selecting an electrical terminal or connector, consider the environment in which the vehicle or equipment will be used or kept. If your area is prone to extreme high and39880 low temperatures, as well as significant moisture and debris, such as construction or maritime equipment, you should choose a sealed connector system like the Amphenol AT SeriesTM.

Strain Reduction

Many heavy-duty connections include built-in strain relief in the form of expanded housing, such as the Amphenol ATO6 Series 6-Way connector plug38160 (below right). Strain relief protects your connector system by keeping wires enclosed and preventing them from bending where they touch the terminals.
