Hello, Welcome to Dasenic

Connectors and Interconnectors Category Description

Connectors and Interconnects are key components used in electrical and electronic systems to achieve the transmission of electrical signals, currents or optical signals. As one of the professional connector distributors, Dasenic provides you with a wide range of electrical connectors and interconnect solutions to assist in the success of your project.

Connector Definition

Connectors is a mechanical device that connects two or more electrical, optical or fluid conductors together. They can transmit signals, currents or other media in an electrical system. The main function of a connector is to provide a detachable interface that enables different parts of a circuit or system to connect and communicate with each other, while also allowing the assembly, repair and replacement of equipment to become more convenient.

Main Types of Connectors

Depending on different applications and functions, connectors can be divided into many types:

Power connectors: used to transmit electrical energy, such as DC plugs, AC power plugs, terminal blocks, etc.

Signal connectors: used to transmit data or signals, such as usb-c connector USB interfaces, HDMI interfaces, audio jacks, etc.

RF connectors: used for high-frequency signal transmission, such as coaxial connectors (BNC, SMA, etc.).

Fiber optic connectors: used to transmit optical signals, such as SC, LC, ST fiber optic connectors.

Circular connector: usually used in industrial or military environments, providing better sealing and mechanical strength.

Board-to-board connector: used to connect signals or power between circuit boards, such as pin headers, female headers, etc.

Basic structure of connectors

Connectors usually consist of the following parts:

Plug and receptacle: The plug is the part that can be inserted into the receptacle, and the two are used together to form a complete connection.

Contacts: This is the part of the connector that actually transmits electrical signals or currents, usually made of metal.

Insulator: Isolates the contacts to prevent short circuits while protecting the internal structure of the connector.

Housing: Wraps the contacts and insulators, provides mechanical protection, and helps align the plug and receptacle.

Locking mechanism: Some connectors have locking devices to ensure that the plug and receptacle are tightly connected and will not loosen easily.

Interconnection definition

Interconnection refers to a system that connects multiple electrical or electronic components together, including wires, connectors, cable assemblies, copper traces on printed circuit boards (PCBs), etc., to form a complete electrical path or communication link.

Interconnection Types

Cable Assemblies: Consists of multiple wires and connectors used to achieve electrical connections between devices or modules.

Printed Circuit Board (PCB): Interconnects components on a circuit board through copper traces to form a complete circuit.

Flexible Printed Circuit Board (FPC): Flexible printed circuit boards allow complex electrical connections in a small space and are widely used in mobile devices and wearable devices.

Jumpers and bridges: Used to create temporary or permanent electrical connections on a PCB or between different circuits.

Backplane: Used to connect multiple circuit boards or modules in a complex system, commonly used in servers and communication equipment.
