The DB connector is a very common D-sub connector, also known as a D-sub miniature, and is widely used as an electrical connector in computers. The D-sub connector features a parallel pin arrangement and is enclosed by a metal shield. The shield terminates in a short projection that resembles the letter “D.”

A DB connector generally refers to a solder-wire-type D-sub connector.
Regarding the classification of DB connectors:
By purpose:
High-current DB connector
Waterproof DB connector
By material:
Simple DB Connector
Traditional DB connector
By type:
Male DB connector
Female DB connector
DB connectors have both male (plug) and female (socket) interfaces. Each component in these connector series is designated with a “D” followed by another letter (indicating the interface size), a number (indicating the number of pins or female contacts), or the letter “P” or “S” (with “P” denoting the male connector and “S” denoting the female connector).
As mentioned above, DB connectors are typically wire-terminated D-sub connectors, meaning they are used for wire-to-board applications. Below, Adam will outline the key considerations when soldering DB connectors:
(1) It is recommended to first apply a layer of thermal-insulation adhesive tape to the inner mold before tinning the copper foil, in order to prevent the core wire from being scorched during the tinning process or when overmolding the outer mold.
(2) The coated copper foil shall not have any seams or damage;
(3) If any damage is found on the copper foil, cover the damaged area with additional copper foil, and then completely solder the joint between the added foil and the original foil using solder.
(4) After the copper foil has been completely wrapped, no internal mold or core wire shall be visible from any viewing angle.
(5) During welding, take care not to scorch the core wire.
(6) Solder shall not be allowed to melt into the gaps between the inner mold and the connector, nor shall solder be permitted to penetrate the insulating adhesive tape of the inner mold.
As a form of serial communication, D-sub connectors are widely used to connect peripheral devices such as printers, scanners, mice, and joysticks to personal computers, while also playing a crucial role in industrial data transmission applications.
As a leading brand in industrial connectors, the D-Sub series is one of ADAMICU’s most important product lines. We not only offer a comprehensive range of standard products with extensive part numbering, but also provide customized solutions tailored to customers’ specific application environments.
