Description

Technical Field

[0001] The present invention relates to the technical field of PCBs, and in particular to a terminal block assembly and a PCB overall device. Background Art

[0002] PCB refers to a printed circuit board, which is a very common electrical device inside electrical appliances in the prior art. It is used to control and connect the circuits of the electrical appliances, control the flow and closing of current, and realize the control of the electrical appliances. Because multiple circuits need to be electrically connected on the printed circuit board, multiple terminals are installed on the printed circuit board to electrically connect the circuits with the terminals at corresponding positions. During the use of the printed circuit board, damage between the printed circuit board and various electrical components is inevitable. Sometimes, some terminals on the printed circuit board may be damaged. On the printed circuit board, some spare terminals are generally reserved. After the terminal in use is damaged, the circuit that has been tested to be undamaged can be electrically connected to the new terminal to ensure that the appliance can be used as soon as possible.

[0003] However, this requires that unused terminals on the printed circuit board must first be protected from dust while waiting to be used, so as not to affect the subsequent use of the terminals. However, because the terminals on the printed circuit board are not arranged neatly, it is difficult to implement a structure on the printed circuit board in the prior art to provide targeted protection for the reserved terminals while ensuring normal circuit connectivity.

[0004] In addition, when using multiple terminal blocks installed on a printed circuit board, multiple terminal connection wires are generally connected to the terminal blocks, and the plastic shells provided on the outside of the multiple terminal connection wires are usually engaged in parallel as a whole to connect to the multiple terminal blocks.
