Electrical Symbols — Terminals and Connectors

Electrical Symbols — Terminals and Connectors

An electrical connector, is an electro-mechanical device used to join electrical terminations and create an electrical circuit. Electrical connectors consist of plugs (male-ended) and jacks (female-ended). The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. Read more

This pinout diagram example showing a VGA connector (as viewed from the socket) was redesigned from the Wikimedia Commons file: DE15 Connector Pinout.svg. []
"A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on some older VGA cards, which has the same shell size but only two rows of pins).
VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed by plugging the female connector hole; this prevented non-VGA 15 pin cables from being plugged into a VGA socket. Four pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5 V DC power supply.
The VGA interface is not engineered to be hotpluggable (so that the user can connect or disconnect the output device while the host is running), although in practice this can be done and usually does not cause damage to the hardware or other problems. However, nothing in the design ensures that the ground pins make a connection first and break last, so hotplugging may introduce surges in signal lines which may or may not be adequately protected against. Also, depending on the hardware and software, detecting a monitor being connected might not work properly in all cases." [VGA connector. Wikipedia]
The pinout diagram example "VGA connector pinout" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Audio and Video Connectors solution from the Engineering area of ConceptDraw Solution Park. Read more

Electrical Symbols, Electrical Diagram Symbols

When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.

Wiring Diagrams with ConceptDraw PRO

A Wiring Diagram is a comprehensive schematic that depicts the electrical circuit system, shows all the connectors, wiring, signal connections (buses), terminal boards between electrical or electronic components and devices of the circuit. Wiring Diagram illustrates how the components are connected electrically and identifies the wires by colour coding or wire numbers. These diagrams are necessary and obligatory for identifying and fixing faults of electrical or electronic circuits, and their elimination. For designing Wiring Diagrams are used the standardized symbols representing electrical components and devices. ConceptDraw Solution Park offers the Electrical Engineering solution from the Engineering area with 26 libraries of graphics design elements and electrical schematic symbols for easy drawing various Wiring Diagrams, Electrical Circuit and Wiring Blueprints, Electrical and Telecom schematics of any complexity, Electrical Engineering Diagrams, Power Systems Diagrams, Repair Diagrams, Maintenance Schemes, etc. in ConceptDraw PRO software.
