Brief Introduction to Electronic Connectors and Cables

Electronic connectors and cables mainly consist of cables and various types of electronic connectors. Electronic connectors are devices that join electronic circuits. They are used in assembling, installing, and supplying power to electrical devices. Connectors are an important component of every electronic equipment used in industrial machinery, consumer electronics, communications, and home and commercial appliances. These devices are often overlooked, but they make every electronic product functional and complete. Most connectors are temporary or removable; some are used as permanent electrical joints. The two main components of an electrical connector are its contacts and housing, also referred to as its plug or receptacle. The housing holds the terminals and ensures the stability of their connections. It isolates the terminals from other electronic components and prevents short-circuiting. Plugs and receptacles protect the terminals from the elements and weather and are made from insulating materials such as molded plastics or ceramics. Connector terminals are the pins that provide a continuous path for the electrical current to flow between circuits. They are made from electrically conductive materials such as brass, phosphor bronze, beryllium copper, and high copper alloy.

Types of Electronic Connectors and Cables

Board-to-Board Connectors
Board-to-board connectors are a group of connectors that join two printed circuit boards (PCB) without using a cable. These connectors consist of a male and a female member and are assembled with PCBs via through-hole technology or surface mount technology. PCBs can be connected in a perpendicular or parallel configuration. A mezzanine connector connects PCBs in a stacking configuration, while an edge connector mates the edges of single-sided or double-sided PCBs.

Barrel Connectors
Barrel connectors, also known as coaxial power connectors, connect electronic devices to an external power source. Low voltage DC is obtained from a wall-mounted adaptor and transmitted to the electronic device through the barrel connector. These connectors are widely used in consumer electronics and are available in standard diameters and lengths. The barrel plug consists of concentric metal sleeves separated by an insulator. The inner sleeve accepts the barrel jack pin. The barrel jack may be PCB-mounted, panel-mounted, or cable-mounted. A cantilevered spring is fitted inside the jack and pushes the outer sleeve of the plug for the inner sleeve to touch the pin.

IEC Connectors
IEC connector is a category of connectors that meet IEC standards. IEC 60320 is the standard specifying the components for connecting power supply cords to electrical equipment with a voltage rating of 250 V and a current rating of 16 A. There are different types of standardized IEC connectors that vary on the current rating, temperature rating, dimensions, and number of terminals. The components of IEC connectors come in pairs which consist of a connector (male component) and an inlet (female component); each IEC component is identified by the prefix “C” followed by a number. Examples of IEC connector components are the C13 connector and C14 inlet, which have three conductors, a current rating of 10 A, and a maximum temperature rating of 700C.

USB Connectors
USB stands for Universal Serial Bus and are standard connectors used in data transfer and supplying power to electronic devices. They are used in smartphones, computers, and other consumer electronic devices. A USB connector consists of a USB connector (the male component) that is plugged into the USB port (the female component). It has four or more contacts which are shielded and housed in a plastic molded strain relief. It also possesses an asymmetrical structure (except for the USB-C) which serves as the keying mechanism. There are six versions of USBs which are the USB 1.0, USB 1.1., USB 2.0, USB 3.0, USB 3.1, and USB 3.2. The newer versions have the fastest transfer speeds. Some USB connectors can be used with USB ports of older versions (backward compatibility). USB connectors can also be classified based on their receptacles and sizes; USB-A, USB-B, USB Mini (Mini-A, Mini B, and Mini-AB), USB Micro (Micro-A, Micro-B, and Micro-AB), and USB-C.

Audio and Video Connectors
Audio connectors and video connectors are a broad class of electronic connectors used for transmitting audio and/or video signals. These connectors carry either analog or digital signals. These connectors are also composed of male (plug) and female (jack) components. The signal systems for audio connectors can be monophonic (single audio channel) or stereophonic (multiple audio channels).

RF Cables
RF is an acronym for radio frequencies. The cable is a type of coaxial cable that transmits radio frequencies. RF also plays the role of a generic term for various technological needs. For this reason, it is not strange to see individuals refer to RF cables for either wireless or non-wireless transmission. It is easier to transmit radio frequencies using the RF cable. Furthermore, the signals are safer in the shielded cable, that is, the coaxial cable. It also enables the capacity of information over a TV set.

Surveillance Cable
Surveillance cables are designed to connect a variety of surveillance and video equipment. As we all know, the security video surveillance system is an important part of the security technology prevention system. It is an advanced comprehensive system with strong prevention capabilities, but it also depends on the correct deployment of video surveillance cables. Its characteristics are mainly visualization, a large amount of image information, rich information resources, and high accuracy. In terms of technology, the security video surveillance system has developed towards digital integration, high definition, and intelligence. From this, it can be seen that image or video processing and transmission are the keys to the field of digital video surveillance system. Many factors limit the video transmission process, such as choice of copper or fiber, cable transmission rate, maximum transmission distance, and more. Hence, it is very critical to choose the correct security video surveillance cables for short and long distance transmission.

How to the Choose the Right Electronic Connectors and Cables

With an endless variety of connectors and cables types and several crucial criteria to consider, choosing the right one can be downright difficult. However, choosing the right connector and cable is the most efficient and reliable way to modularize, improve or downsize a system so that it runs smoothly without needing frequent repairs. When choosing, you can follow these steps:

Pen Down Your Requirements
How many signals are there in total? What currents, frequencies, and voltages are they carrying? Are your signals analog, digital, or a combination? The combination of signals has an impact on the connector type, pinout, and wiring. For instance, high-frequency signals may need coaxial connection and low-level analog signals may need shielding. Certain signal combinations cannot be included in the same connector. If high voltage pins are involved, you may need to take creepage and clearance distances into account. If there are high current paths, you may need multiple pins and bigger wires. Depending on your unique case and design requirements, you might also need a custom solution.

Consider Your Current Rating and Operating Voltage
Current rating is the most vital criterion for selecting electrical cable connectors. It is a measure of the amount of current that can flow through a mating terminal and is ideally stated in amps per circuit. The flow of current should be adjusted or derated on the basis of the number of circuits in a given housing according to the rise in temperature of the adjacent terminal.

Check for Space Constraints
The size and weight of electrical cable connectors and terminal connectors have reduced in correspondence to the reduction in space available for them. However, their ability to withstand an increase in plugging and unplugging frequency has increased considerably. So, depending on the situation that applies to your project and its design needs, you may need to look for more options in electric connectors.

Verify the Recommended Operating Temperature Range
Most electric connectors are subjected to extreme conditions like vibration and shock. Electric cable connectors and terminal connectors that are designed for extreme conditions and hazardous environments incorporate special features that resist vibration and shocks and withstand extreme temperatures. So, choose your electric connector depending on the location of your electric connector, the proximity to a heat source, operating temperatures, and the frequency of plugging and unplugging.

Confirm the Level of Reliability
Reliability is another vital factor that needs to be considered when buying electric connector. However, reliability is a complicated concept which depends on several factors. Accurate figures are difficult to determine but some connectors come with a specification for mean time to failure. This serves as a guide for selecting the right electric connector for any application.

Make Sure It has Environmental Sealing
Certain environments require protection against invasion of combustible or inflammable gases, vapors, dust or liquids. Electric connectors come with environmental sealing options that are effective against unexpected splashes. Once you know the level of safety required, you can verify the IP rating number in the IP code system and know if you are investing in the right electrical connectors. Environmental sealing is a very important criterion for safer workplaces, especially in stringent environments like aerospace, space, underwater and medical and food applications.

Factor in Materials and Plating
Terminal materials and plating are often the last factors to be considered but since most electric connectors are made using nylon plastic, they have inflammability ratings for high resistance to flame continuance. The standard options available include tin, lead and select gold which are suitable for most applications. Base materials are typically available in phosphor bronze or brass as they offer excellent strength and current-carrying capabilities even with prolonged exposure to high ambient temperatures.

Calculate the Pricing
The price of electric connector is typically calculated based on the total cost which includes the receptacle and the plug, the cost of terminal connectors, and the labor cost for attaching the electrical wire to the terminal and inserting it into the housing. The criterion that matters the most to you will dictate the type and size of the electric connector. Other factors that you need to consider here include the operating voltage, the size of the wire, the configuration, engagement force, and the size of the circuit.
