Electrical connector charts usually include information on the method of connection that a particular connector uses and how a wire fastens to and terminates from the connector. Many electrical connector charts also include information on the physical characteristics and designated performance standards of connectors. Electrical connector charts are generally presented in a visual format with photographs of the connectors and their corresponding wires or in a tabular format with textual descriptions of the connectors and their various features.
Electrical connectors are mechanically assembled devices used to establish an interface to exchange information between electrical circuits, either temporarily or permanently. Electrical connector charts often organize electrical connectors by the type of interface they establish. Terminal blocks, for instance, join multiple wires to a single terminal enclosed within a protective casing. Plug-and-socket connectors, on the other hand, utilize a grid of pins on the male end and a congruent array of receptacles on the female end to establish a connection.
Plug-and-socket connectors often come with connector charts and diagrams due to the large variety of standards available on the market, such as VGA, HDMI and DVIW. A connection chart also often includes that connector's specific performance parameters such as acceptable voltage and current.
