Temperature At The Terminal:

There are two possibilities: the terminal is loose and the contact resistance is too large, thereby overheating; the terminal is not loose, but the circuit has overcurrent heating due to some unknown reason, such as the power supply voltage is too high, or the load is short-circuited.

1. The voltage is too high. It can be checked from the source. The secondary voltage of the transformer is the voltage in the distribution box and the voltage of the electrical equipment. The socket can also have assembly buckles and locking buckles. The assembly buckles can play a more stable Fixed to the PCB board, the locking buckle can lock the mother body and the socket after the installation is completed. A variety of socket designs can be matched with different mother body insertion methods, such as: horizontal, vertical or inclined to the printed circuit board, etc. Choose metric wire gauge or standard wire gauge.
