Electrical connectors are electromechanical devices used to create an electrical circuit by mating electrical terminals. These connectors come in a variety of sizes and shapes and have many unique properties. Their characteristics include their gender, as they can be male or female, their polarity, or the pattern of their contacts.
A USB connector, for example, has standard polarization because it can only be inserted one way and has standard metal shielding that is not part of the electrical circuitry, which helps keep the signal intact in an environment with a lot of electrical noise. However, there is a wide range of USB connectors, such as USB-A, USB-B, USB-Mini and USB-Micro, which can be further broken down into male and female categories.
Connectors are something most people encounter or use on a daily basis without knowing much about how they work. Whether it’s an RCA, IEC, power connector or a hybrid connector , most of us have to deal with such devices, although we may not know their names or the specific terminology. Aside from USBs, phone plugs are among the most commonly used types. Telephone connectors are used for low-voltage, low-voltage applications, as well as for microphone cables.
Power outlets, commonly known by designations such as “socket”, “socket”, or “socket”, allow electrical equipment to be connected to the primary power source in the building and are designed to protect the equipment individually from accidental contact with energized conductors . Sockets vary widely in terms of shape, voltage or plug type, and while they are standardized, different norms apply to different parts of the world. To ensure maximum safety, they often include features such as insulated sleeves or are only designed to accept compatible plugs.
Also among the list of commonly used connectors is the “banana plug”, which is often used with test equipment because it connects individual wires. A lesser-known but more sophisticated type is the hybrid connector, which allows mixing multiple types of both electrical and non-electrical connectors, as well as fiber optic connectors. They are modular in design and prove very helpful in simplifying the assembly process or repair while allowing the manufacture of composite cable assemblies.
Audio and video connectors, which can be either electrical or optical, carry audio and video signals. Over the years as technology has advanced more and more options have been made available to the public, from RCA and XLR to DIN and TOSLINK depending on the needs of each individual device. Whether it’s analog audio and analog video or digital audio and digital video, there is no connector that fits all needs, but progress has been and nowadays many connectors are compatible with multiple hardware devices. Due to the uniqueness of each connector and their visual differences, they are easy to identify. As more electrical devices were created, the demand for simple,
