dc plug 5.5 x 2.5 mm

PA2507 5.5mm 2.5mm Dc Power Connector 

DC connector is a multi-functional, high-density connector with good electrical characteristics, widely used in automotive electronics, household appliances, industrial control and information communication and other fields. The DC connector consists of three parts: contact piece, plug-in board and housing.

The DC connector consists of three parts

contact piece
A contact is a part used to connect more than two conductors, and attention should be paid to distinguish between resistance connection and electrical contact connection. A circuit connected by electrical contact has a small current (such as resistance), and its resistance value is not affected by the ambient temperature; a circuit connected by resistance has a large current (such as the resistance value is determined by the ambient temperature), but its resistance value will change with the ambient temperature .

Resistance is the contact resistance between two conductors. When a current in one conductor flows through another conductor, a voltage is generated across it, and this voltage is the voltage between the two ends of the conductor. The voltage is proportional to the magnitude of the current, that is, the greater the current, the greater the voltage generated. Normally, in general electrical equipment, the voltage value generated by electrical contact connection is smaller than the resistance value; in some special cases, a voltage greater than the resistance value may be generated, such as in transformers, rectifiers, semiconductor switching circuits, etc. .

The plug-in board is a board that connects connectors, devices and components. It is a part with simple structure, few functions and easy maintenance and repair. The plug-in board is composed of a plug-in slot and a plug-in board. It has a compact structure and is easy to maintain and repair. It is mainly used between low-power devices and higher-power devices, and can also be used between high-power devices (such as computers) and smaller power devices ( such as ordinary TV sets). There are many powerful and common devices on the plug-in board, such as motor controllers, power converters, battery chargers and inverters. These devices or components must be able to withstand various environmental conditions such as current, voltage and vibration.
