Basic Flowchart Symbols and Meaning

The vector stencils library "Audio and video connectors" contains 94 symbols of audio and video connectors (TRS, TS, XLR, microphone, headphone, TOSLINK, DVI, VGA, DFP, S-Video, RCA, display port, HDMI, Thunderbolt, coaxial TV, F connector, MIDI) and device silhouettes.
Use these jacks and plugs clipart icons for drawing hook up diagrams.
"Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise." [Audio and video connector. Wikipedia]
"The existence of many different audio and video standards necessitates the definition of hardware interfaces, which define the physical characteristics of the connections between electrical equipment. This includes the types and numbers of wires required along with the strength and frequency of the signal. It also includes the physical design of the plugs and sockets.
An interface may define a connector that is used only by that interface (e.g., DVI) or may define a connector that is also used by another interface; for example, RCA connectors are defined both by the composite video and component video interfaces.
Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise.
Since both analog and digital signals are used with some styles of connectors, knowledge of the interface used is necessary for a successful transfer of signals. Some interface types use only a distinctive connector or family of connectors, to ensure compatibility. Especially with analog interfaces, physically interchangeable connectors may not carry compatible signals.
Some of these connectors, and other types of connectors, are also used at radio frequency (RF) to connect a radio or television receiver to an antenna or to a cable system..." [Audio and video interfaces and connectors. Wikipedia]

The vector stenvils library "Outlets" contains 57 symbols of electrical outlets for drawing building interior design, electrical floor plans and layouts of AC power plugs and sockets.
"AC power plugs and sockets are devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building. Electrical plugs and sockets differ in voltage and current rating, shape, size and type of connectors. The types used in each country are set by national standards, some of which are listed in the IEC technical report TR 60083, Plugs and socket-outlets for domestic and similar general use standardized in member countries of IEC.
Plugs and sockets for portable appliances started becoming available in the 1880s, to replace connections to light sockets with easier to use wall-mounted outlets. A proliferation of types developed to address the issues of convenience and protection from electric shock. Today there are approximately 20 types in common use around the world, and many obsolete socket types are still found in older buildings. Co-ordination of technical standards has allowed some types of plugs to be used over wide regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Some multi-standard sockets allow use of several different types of plugs; improvised or unapproved adapters between incompatible sockets and plugs may not provide the full safety and performance of an approved adapter."
