Therefore, the technical scheme of the embodiment effectively solves the problem that the male plug in the related technology is only plugged with the female seat along a single direction, so that the assembly efficiency of two adjacent display units is low. In addition, as the female socket 20 and the male plug 50 can be quickly inserted, the power line which is convenient to be connected with the female socket 20 and the male plug 50 can be quickly connected, the maintenance is convenient, and the production efficiency is improved.

The first direction may be a front-back direction, the second direction may be a vertical direction or a horizontal direction, and the specific direction may be determined according to the positions of the female socket 20 and the male socket 50 mounted on the display module of the LED display device.

Specifically, the number of the plug-in portions 22 is three, and the number of the conductive posts 52 is three.

As shown in fig. 1 to 6, adjacent two sides of the two conductive sheets 221 each include a concave section 2211 and first and second convex sections 2212 and 2213 connected at both sides of the concave section 2211.
