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.

There are hundreds of types of electrical connectors. Connectors may join two lengths of flexible copper wire or cable, or connect a wire or cable to an electrical terminal.

How to Create an Electrical Diagram Using Terminals and Connectors Library

  • Open ConceptDraw DIAGRAM new document page.
  • Select libraries from Electrical Engineering section.

    Libraries from Electrical Engineering section

  • There are a few different ways to place an object into your drawing:

    • Click on an object and then click on the document, at the place you want the object to be inserted.
    • Perform a drag-and-drop from the library to your document.
    • Double click on an object’s icon in the library to place an object in the center of your document.
  • Select the Smart Connector tool Smart Connector. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
  • Result: Electrical Diagram.

CAD Drawing Software for Making Mechanic Diagram and Electrical Diagram Architectural Designs →

This diagram represents the electrical floor plan. This is a common practice - to draw the electrical plan on the floor plan. The outlets, fixtures and other electrical equipment are depicted on the floor plan with special symbols. This drawing was created using the possibilities of ConceptDraw DIAGRAM as CAD software. Computer-aided design software is intended to replaces manual engineering drafting with an automated process. CAD software is used by engineers, architects, and others to make high-precision technical drawings and illustrations. CAD software allows technical specialists to develop, examine and manage various engineering projects. It is almost impossible nowadays to imagine mechanical engineering without digital technologies. Finding a suitable CAD software for creating mechanic diagram and electrical diagram architectural designs can take a lot of time and effort. However, with ConceptDraw DIAGRAM you can create any diagram that you want and later convert it to the most popular graphic formats like.vsdx,.png,.pptx etc.ConceptDraw DIAGRAM software for making mechanic and electrical diagrams for architectural design

Building Drawing. Design Element: Piping Plan →

A technical drawing of a building is called an architectural drawing. According to a set of conventions, a building drawing includes a number of views, as well as unit measurements, scales, sheet sizes, cross referencing and annotation. Computer progress had a major impact of the methods of architectural drawing, making manual drawing almost obsolete. Digital drawing software, such as ConceptDraw DIAGRAM , offers a number of tools for each design element: piping plan, floor plan, etc. Any building should have its plumbing and piping plans for every room, that has a water supply. Plans are applied to indicate arrangement of piping system in the building. This diagram presents a suite of standard piping icons for making building plans that include plumbing and piping layout. This diagram was designed using ConceptDraw solution for Piping and Plumbing planning. Using symbols is valuable for making a valid piping plan. Because any professional will properly interpreted such plan as a piece of technical documentation of a construction project.Building Drawing. Design Element: Piping Plan *

Flow Chart Symbols →

If you need to describe some process, diagramming is a perfect tool for almost any imaginable purpose. The set of the most commonly used flow charts symbols is quite wide and includes symbols for operations, processes, data inputs and outputs. You can see the full list of all the symbols used for flowcharting in Flowcharts solution from Diagrams area in ConceptDraw Solution Park. A flow chart is often used for visual representation of a sequential process flow. The flowchart approach to any process is to divide it into some sequential actions. What makes a flow chart so popular and clear to make out is the set of standard flowchart symbols that has the same reading independently from processes described with their applying. The current drawing represents the vector library containing the pack of standard flowchart symbols. This library is supplied with ConceptDraw Flowcharts solution.Flow Chart Symbols *

Electrical Symbols — Transistors →

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM 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.Electrical Symbols — Transistors *
