Abstract: An electrical connector includes a lens module, an insulating casing and a plurality of terminals. An outer edge of the lens module is wrapped by coils. The insulating casing has an accommodating space for accommodating the lens module. The bottom of the insulating casing is formed with a plurality of terminal troughs. The plurality of terminals is accommodated in the terminal troughs respectively. Each terminal has two ends. One end extends into the accommodating space to be electrically connected with the lens module, while the other end extends beyond the insulating casing. An engaging means is provided between the inner edge of the insulating casing and the outer edge of the lens module. Via the engaging means, the lens module can be engaged in the accommodating space of the insulating casing firmly.
