DC sockets generally consist of three pins, but usually only connected to two pins,DC sockets center
pin is positive, socket edge is negative, connected to the MCU and socket connected to the core VCC
,VCC tube DC socket pins are grounded, one side of the pin is usually fixed and cannot be connected
(the pin is used to connect the battery) side pin and bottom pin when inserted into the DC socket con-
nection. Then connect the pin behind the DC socket to the circuit board ground, and connect the
bottom of the pin to the positive circuit board (if battery power is used, connect the side of the pin
to the positive battery).
DC Connector Jack’s Structure
DC socket is a kind of socket matching with the special power supply for computer display. It is composed
of transverse socket, longitudinal socket, insulating base, forked contact shrapnel and directional keyway.
The two forked contact shrapnel are located in the center of the base, arranged vertically and horizontally,
and are not connected with each other
DC Connector Jack’s Feature
Easy to connect: SMD-mounted DC sockets are easy to connect, allowing DC power plugs to be easily
inserted into the sockets and securely remain connected.
Stable and reliable: The receptacle has a high fit with the circuit board, making the connection stable
and reliable and able to maintain a long continuous working condition.
High density installation: SMD DC power receptacles can be installed with high density through SMD
installation, making full use of the resources on the entire board.
Wide applicability: SMD DC power sockets are suitable for a wide variety of electronic devices, such as
computers, mobile devices, network devices, etc.
