At present, the electric connector after assembly has excellent contact performance.

[0033] The board end electric connector is a connector for connecting the conductor wire harness to the PCB, which plays an important role in bridging between the conductor and the circuit board in electronic equipment and system.

[0034] However, the current board end electric connector is directly welded on the PCB and establishes electrical connection between the PIN needle and the circuit on the PCB. When the board end electric connector needs to be replaced, the disassembly process is complicated.

[0044] When assembling, the end of the positioning sheet 30 away from the plug-in gap 33 can be provided with a positioning sheet material belt, the positioning sheet 30 is fed and pushed by the positioning sheet material belt, so that the plug-in gap 33 gradually contacts and inserts into the clamping socket 16 of the board end electrical connector 10 until the second plug-in protrusion 17 and the plug-in gap 33 complete the plug-in matching. After the assembly is completed, the positioning sheet material belt can be removed.
