Description

POWER TERMINAL AND SOCKET CONNECTOR COMPRISING THE SAME Technical Field [1] The present invention relates to a power terminal,

Generally, when the substrates are interconnected, two connectors are used which are connected to the respective substrates by a method such as soldering, and the two connectors can be connected to each other. Here, one of the two connectors is a plug connector and the other is a socket connector. The plug connector and the socket connector may be fastened together to form an electrical connector assembly.

This misassembly can cause the electrical connector assembly to deform or break.

In addition, since the power terminal of the socket connector can be reduced in size, the strength of the power terminal and the circuit board can be reduced and the power terminal may be separated from each other.
