Abstract

The utility model relates to an electrical connector module which comprises a casing body, a circuit board provided with a light emitting element and a light guide member. One end of the light guide member is surrounded by a second rib at the periphery of a light guide bar. The casing body is correspondingly provided with a first groove. The second rib is positioned and assembled in the first groove to form a closed positioning relationship, which can effectively prevent electrostatic. The other end of the light guide member is provided with a narrowing convex rib which extends at the opening of the accommodating groove. The convex rib abuts against the circuit board. When an upper casing body and a lower casing body are buckled by welding, a machine imposes pressure on the upper casing body and the lower casing body. The convex rib slightly and elastically deforms under the pressure from the casing body, thus the pressure is buffered or dissolved, the casing body is prevented from damage, and the light guide bar is prevented from protruding from the outer surface of the casing body and from leading to poor appearance.
