By adopting this technical scheme: when the socket part and the plug part are connected as one, the fool-proof protrusion just extends into the fool-proof concave block, thereby achieving the technical effect of preventing the socket part and the plug part from being misaligned.

Further preferably, in the above-mentioned electrical connector: both the socket housing and the plug housing are provided with numeral identification bumps.

Still further preferably, in the above electrical connector: the conductive insert is L-shaped, and its tail protrudes from the side end of the plug housing.

Still further preferably, in the above-mentioned electrical connector: anti-slip lines are provided on the outer wall of the socket housing.

By adopting this technical solution: using digitally marked bumps to prevent misalignment of wiring, and the plug part is fixed on the PCB board by the side part instead of the traditional lower end part, which optimizes the board layout design of the PCB board.

Compared with the prior art, the utility model provides comprehensive electric shock protection, convenient connection/unplugging, compact layout, meeting the installation size of 4U chassis, and the number of connection points increases to 32. Features.
