How They Work
Electronic connectors play a crucial role in establishing reliable connections between electronic components and devices. They work by providing a secure physical and electrical interface between male and female connector parts. These connectors are designed with specific pins or terminals that align and make contact when mated, creating a conductive path for electrical signals or power to pass through.
The mating process is generally user-friendly, often incorporating guiding keys or polarization to ensure proper alignment, reducing the risk of misconnection. The connectors also feature a mechanical lock when mated, preventing accidental disconnection due to vibrations or movement.
Inside the connectors, electrical contacts made of conductive materials like copper, gold, or silver facilitate efficient signal transmission with low resistance. These contacts are engineered to maintain a stable connection, even in challenging environmental conditions such as temperature fluctuations, humidity, or mechanical stress.
The relevance of AC (Alternating Current) and DC (Direct Current) currents in the context of electronic connectors lies in the type of application they serve. AC currents periodically reverse their direction, constantly changing polarity. Connectors designed for AC applications must consider factors like impedance, capacitance, and inductance to ensure minimal signal distortion and efficient power transfer. AC connectors are commonly found in devices that require high-frequency data transmission, power distribution, and applications such as audio and video equipment.
On the other hand, DC currents flow in a constant direction without reversing polarity. Connectors used for DC applications focus on ensuring low resistance to maintain steady power delivery and reliable data transmission. DC connectors are prevalent in applications like power adapters, battery-powered devices, and digital data transfer systems.
The choice between AC and DC connectors is essential, depending on the specific needs of the application. They are designed to cater to the unique requirements of different electronic systems, allowing for optimized performance, efficiency, and safety.
In summary, electronic connectors serve as indispensable components in modern technology, establishing reliable connections between electronic devices. They facilitate efficient signal transmission and power delivery by providing a secure interface between male and female parts. Additionally, the relevance of AC and DC currents lies in the specific application each type of connector serves. AC connectors are suitable for high-frequency data transmission and power distribution, while DC connectors are ideal for steady power delivery and digital data transfer. The careful consideration of these factors ensures the optimal performance and functionality of electronic systems in various industries and applications.
When designing an electronic connector, manufacturers must think about a number of different factors. First, they must consider the environment that the electronic connector must work in and they have to think about things like:
- To what the electronic connector must connect
- The maximum and minimum surrounding temperatures
- What level of mechanical stress can they expect the connector to experience
- Whether or not there are any existing connectors with which the new connectors must be compatible
- Whether or not the user will be frequently plugging and unplugging the connector, etc.
Based on these considerations, among others, electronic connector manufacturers will decide on technical details like pitch (distance between the respective centers of separate connector contact pieces, both female and male), durability/mating cycles (the length of time you can expect your connector to last if you use it normally), versatility, voltage type, current type, etc. Manufacturers must also decide on electronic connector sizes and materials.
To increase the versatility of an electronic connector, manufacturers can add custom features such as extra contacts, adaptability features, seals between the enclosure and insert (to protect against oil, water, and other moisture), corrosion-blocking anodized shells, and/or strain relief features. (Strain relief features keep harmful mechanical forces from reaching the electronic connector.) To customize an electronic connector, manufacturers can also change the number and types of pins it has. Learn more about the possibilities of custom electronic connector design by talking with your potential suppliers.
There are many different kinds of electronic connectors. However, in general, they feature a few key parts. These include contacts or terminals, a housing, locking features, and keying features.
Contacts or terminals are the parts of the connector that create the actual connection. Male connector contacts are also often called “pinouts” because they are generally extended metal pieces, like pins or prongs.
The contact system is one of the most important parts of an electronic connector because it establishes the density requirements, contact forces, and other mechanical features of the connector.
Manufacturers make contacts and terminals almost exclusively from highly conductive non-corrosive metals, such as phosphor-bronze, beryllium copper, modified copper, or brass.
Housings encase the contacts and protect them from exposure to or collision with outside elements or people. Typically, manufacturers make housings from plastic, though they do sometimes make them from dielectric or insulating materials instead.
Locking features are elements designed to lock in a mating connection so that it properly locks in place. Without locking features, the connection could disconnect before you want it to.
Keying features, also known as polarizing features, make sure that you can only mate a connection if both connections are properly aligned and oriented. Without this feature, users could incorrectly plug in a connector and break it.
The three main types of electronic connectors are as follows: temporary, assembly required, and permanent.
A temporary electronic connector is typically used in portable equipment where the connector’s lifespan will probably be short.
Assembly required electronic connectors are best in applications where more longevity and even the option of removal or replacement down the road is needed.
Permanent connectors are used in applications where they will be expected to perform in one place over the long term.
A further categorization of electrical connectors differentiates them as male and female.
A male connector is used to plug into electrical circuits. Male connectors use metal extensions, like power plug prongs, to connect to the female connector.
A female electronic connector acts as a socket connector. It features a receptacle to receive electrical circuits by connecting to male connectors. One of the most common examples of a female connector socket is the wall plug.
Manufacturers produce many different types of electronic connectors for specific purposes, but a few types are very common in industrial applications. Pin connectors, cable connectors, wire connectors, fiber optic connectors, and amp connectors are among the most common connector types.
Pin connectors are connectors that use pins (sharp pointed and blunt headed pieces of metal wire) to connect electrical circuits. Usually male configured, they generally plug into or otherwise connect to female-configured electrical circuits like sockets. Together, pin and plug connector assemblies can be called socket connectors, pin and socket connectors, or plug and socket connectors.
Cable connectors are a type of electronic connector that manufacturers design specifically to connect cable cords and electronic components. Once joined they can conduct electricity or send communication. Cable connectors are usually composed of a set of flexible wires or stranded wires housed inside a plastic coating. They most often work using a plug or a screw.
Wire connectors are connectors in the very broad category of connectors made out of wire or with wire components.
Fiber optic connectors are connectors that manufacturers create using very fine glass fibers. Fiber optic connectors are perfect for specialized communications setups.
Amp connectors, also known as Amphenol connectors, are connectors that vary in the amount of electric current, or amperage, that they can transfer. They are named after the first company to manufacture them, the Amphenol Corporation. Amp connectors may transmit either AC or DC power. Some of their most common applications include battery, PV array, sub-array, PV, and solar power array connecting.
Some less common types of connectors are DIN connectors, RF connectors, coaxial, and PCB connectors.
DIN connectors are manufactured to standards set by the Deutsches Institut fur Normung (DIN), the German national standard organization.
A coaxial connector has many sub-types, but essentially it is a cable that can maintain a connection.
PCB connectors are connectors designed specifically to work with printed circuit boards. They accommodate the many interconnected and small parts of printed circuit boards.
RF connectors, another type of coaxial connector, work with radio frequencies in a multi-megahertz range.
Other miscellaneous electronic connector types include waterproof connectors and power connectors.
Waterproof connectors work just as they sound; they resist water. Manufacturers can make all different kinds of waterproof connectors, but they work especially well for equipment that could be exposed to the rain, like amplifiers and other audiovisual equipment, as well as tools like wire connectors and plugs for cars, trucks, motorcycles, and marine vehicles.
Power connectors transport large amounts of power from a power source to whatever equipment or electronic devices that require that power.
Electronic connectors face competition from alternative methods of establishing connections between electronic components and devices, namely soldering and wireless communication technologies. While soldering is widely used in electronics manufacturing, it lacks the versatility and ease of use offered by electronic connectors.

Adaptors bridge the gap between different connector types or sizes, ensuring compatibility. Wire terminal kits offer a selection of components for custom cable assemblies, while repair kits provide essential items for connector repairs. Determining the needed accessories depends on the application’s requirements, such as environmental conditions and mechanical stress. These accessories can be acquired from manufacturers, distributors, online retailers, electronic component stores, or OEM suppliers. Proper selection and utilization of these accessories contribute to the overall reliability and efficiency of electronic connections.
If you want your electronic connectors to last, you must be very careful with them. This is because they are vulnerable to a number of threats. Temporary electronic connectors are especially vulnerable to attacks by mechanical stress. This is because users so often connect and disconnect them. Over time, the subtle vibration and abrasion that connectors experience can wear them out. In general, electronic connectors are vulnerable to attacks from chemicals, because of their metal components. Metal components like metal contacts, if not properly cared for, can develop rust or become dirty.
The best way to protect your electronic connectors from developing problems like those mentioned above is by regularly checking them for visible damage, regularly checking your equipment for issues that could endanger your electronic connectors (e.g. chemical leaks), and not subjecting your electronic connectors to undue stress or harsh environments. Also, if and when you must clean your connectors, make sure you are using an approved cleaner.
