[0002] A conventional connector is composed of a male head and a female seat, and the combination of the male head and the female seat achieves the purpose of electrical connection.

[0003] Generally, for an assembler, the male head needs to be aligned with the female seat in a visible manner to ensure the combination of the male head and the female seat; however, in the application field of, for example, a modular display panel, the display panel shields the male head and the female seat, so that the assembler cannot assemble in a visible manner, especially the assembler can be a non-professional assembler, which invisibly causes the difficulty of assembly, and if the assembly is performed in a rough manner, the male head and the female seat can be damaged, and even the display panel itself can be damaged. In addition to the foregoing problems, if the electrical connector is used in an embedded circuit board, that is, the connector is arranged on a printed circuit board with an opening, since the connector is only fixed to the opening through the electrical terminal, when the connector is connected, the electrical terminal can be separated from the printed circuit board due to the force and extrusion.
