This allows the quick-connect terminal block provided in this application to be applied to a variety of work scenarios.

[0037] The base 1 is the main carrier of the quick-connect terminal board. The first mounting position 11 is used to install the PCB board 2, and the second mounting position 12 is used to install the output part 5. The PCB board 2 is used to realize the connection between the connection part base 3 and the output part 5, so that there is a passage inside the terminal board. The connection part base 3 is fixedly connected to the PCB board 2, and the connection part 4 can be removably plugged with the connection part base 3. The wires that need to be connected to the input end are plugged into the connection part 4, and the connection part 4 is plugged into the connection part base 3 as a whole to complete the connection of the input end wires. During the production line assembly operation, it is actually only necessary to plug the connection part 4 into the connection part base 3 to complete the assembly operation. Compared with the screw or plug connection used at the input end of the traditional terminal board, the number of plug-in times required for the quick-connect terminal board wiring provided by the technical solution is significantly reduced, and there is no need to distinguish the wire function when plugging, thereby improving the production line assembly efficiency and reducing the wire insertion error rate.

The b-end 322 can cooperate with the connecting portion 4 to form a passage, and the a-end 321 is used for welding with the PCB board 2. After passing through the base housing 31, the a-end 321 continues to extend away from the housing, so that sufficient material is reserved and the welding effect is good.

The positioning member 33 cooperates with the base mounting position 21 to determine the connection position of the connecting part base 31 on the PCB board 2, which facilitates the subsequent accurate welding of the first conductor 32.

[0052] The first guide position 411 enables the connection portion 4 to be more accurately plugged into the first conductor 32 , and the snap-in position 418 and the first conductor 32 are correspondingly arranged so that the second conductor 42 and the first conductor 32 can be accurately and correspondingly contacted, resulting in a good terminal board connection effect.

[0053] Refer again Figure 1 and Figure 2 A second guide position 412 is also provided on the connecting portion shell 41; the second guide position 412 is arranged corresponding to the first guide position 411.

[0054] The second guide position 412 provides guidance for the external wire access, so that the wire can be accurately and quickly plugged into the connecting part 4. At the same time, the second guide position 412 can also play a certain limiting role, which can limit the movement of the wire access point and ensure good contact between the wire and the conductor.
