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.

Wiring Diagrams with ConceptDraw DIAGRAM →

It is important to have an electrical circuits scheme, when you plan a renovation or move to a new apartment. You have to arrange interior according to that plan, and it’s trouble-free to create wiring diagrams with ConceptDraw DIAGRAM , furthermore, this software has all the features needed to create an interior plan as well. So, get inspired by tons of examples included to ConceptDraw DIAGRAM solutions, and start your diagramming experience! A wiring diagrams, that are represented on this drawing was created to depict the components of the electrical circuit schemes. These diagrams are created to depict the information about circuit arrangements and connections. Wiring diagrams, in contrast to physical drawings, use standard symbol's notation to depict different circuit devices and connections. That is why, wiring diagrams are applied to discover and repair electrical and electronic circuits. The vector graphic objects provided by ConceptDraw Electrical Engineering solution can help any specialist in electric engineering to design electrical schemes, circuit and wiring plans, power systems charts, and Maintenance and Repair diagrams.Wiring Diagrams with ConceptDraw DIAGRAM

Local area network (LAN). Computer and Network Examples →

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN) diagram
