At present, when two existing electric connectors capable of being butted with each other are welded on a circuit board, the welding parts are almost all arranged in the same direction of the circuit board, for example, the two electric connectors are simultaneously welded and fixed on the upper surface of the circuit board, so that the two electric connectors are arranged in the same direction.

Under the circumstances of rapid development of technology and environmental awareness, light sources (light bars) using light emitting diodes are commonly used, and electrical connectors used in the light bars can achieve electrical connection through the docking structure, but because the light bars are disposed in an electronic product, and the electronic product is thin, the space for accommodating the light bars is limited, so that the electrical connector structure on the circuit board inside the light bars must be matched with the electronic product to reduce the size and be more precise.

Due to the limitation of the accommodating space, if the existing method for installing the electrical connectors is used, the light bar cannot be miniaturized, and therefore the butt joint mode between the two electrical connectors needs to be changed, the light bar can be thinned and installed in the electronic product.

In view of the above-mentioned shortcomings of the conventional electrical connector assembly, the present inventors have eagerly studied and innovated, and after many years of intensive research, successfully developed the electrical connector assembly.
