By setting the guiding bevel 21, the docking accuracy and efficiency of the connectors are improved, the resistance during the docking process is reduced, and the connectors can complete the docking quickly and accurately.

[0035] like Figure 1 As shown, an anti-foolproof groove 40 is provided on either the line-end connector 10 or the board-end connector 20, and an anti-foolproof rib 50 is provided on the other of the two, the anti-foolproof rib 50 and the anti-foolproof groove 40 match each other, and the anti-foolproof fence between the board-end connector 20 and the line-end connector 10 in the existing connector is eliminated, and mutual matching and anti-foolproofing are achieved by adding the anti-foolproof groove 40 and the anti-foolproof rib 50, so that correct matching can be smoothly plugged in and out, and incorrect matching (reverse) will cause jamming; this design makes the line-end connector 10 compact and easy to carry and install.

[0036] During the docking process, the user only needs to align the plug-in end of the line-end connector 10 with the docking end of the board-end connector 20, and then insert the line-end connector 10 into the board-end connector 20 along the guide slope 21. Due to the matching design of the anti-foolproof rib 50 and the anti-foolproof groove 40, only when the docking method of the line-end connector 10 and the board-end connector 20 is correct, the anti-foolproof rib 50 can be smoothly inserted into the anti-foolproof groove 40 to complete the docking process.

[0037] In some embodiments, Figure 1As shown, the guide bevel 21 extends from the outer edge of the board-end connector 20 toward the center axis, and the guide bevel 21 is at least symmetrically arranged; preferably, the guide bevel 21 is arranged on each inner side wall of the board-end connector 20, so that the wire-end connector 10 can be automatically guided after contacting the guide bevel 21 of the board-end connector 20, and can be smoothly matched with the board-end connector 20.

[0038] In some embodiments, Figure 3 As shown, the guide distance d on each guide bevel 21 is 1.2-1.7 mm.
