What is a computer connector?

Computing systems have many accessories and devices that they need to work with for example to transfer data or power. A connector is used to join conductors electrically or mechanically together.

There are lots of different kinds of connectors available that are designed for different applications. Here is an overview of some of the most popular connectors and what they are used for.

D-subminiature connectors types

D-sub connectors have a d-shaped shield that screens interference and 2 rows of pins with varying configurations. They can be cable or board mounted and are commonly used for display and serial-port communications. Our range includes replaceable parts such as backshells (housing), screw locks and contacts. Common types are:

Standard density D-sub connectors
High-density D-sub connectors
PCB D-sub connectors

USB connectors types

Used for both power and data transfer between computers and devices. There are different types of USB connector available:

Type A: Rectangular in shape – the standard USB port
Type B: Almost square in shape, mostly used for peripherals like printers.
Mini & Micro B: Used with small devices such as smartphones, cameras and wearable devices
Type C: The newest and smallest USB connector that is symmetrical in shape with 24 pins, in 2 rows of 12

Memory and sim card connectors

Receptacles for sim and memory storage cards to be used in devices such as laptops, phones and cameras.
