The shielding element 30′ is formed by a metal injection molding (MIM) technology. The shielding element 30′ has a base portion 31′. The base portion 31′ opens a receiving chamber 32′ penetrating through a front surface and a rear surface of the base portion 31′. Two opposite sides of a front surface of the base portion 31′ protrude frontward to form two side boards 33′. An upper portion and a lower portion of the front surface of the base portion 31′ protrude frontward to form two docking boards 34′ connecting with top surfaces and bottom surfaces of the two side boards 33′, respectively. The main portion 11′ is fastened in the receiving chamber 32′. The first tongue portion 12′ and the second tongue portion 13′ are received between the two side boards 33′. The two docking boards 34′ are covered to a top surface and a bottom surface of the first tongue portion 12′, respectively. Front surfaces of the two docking boards 34′ and the first tongue portion 12′ are flush.

However, after the conventional electrical connector 100′ is docked with a docking connector frequently, metal scraps (not shown) are easily produced from the two docking boards 34′, in addition, front ends of the two docking boards 34′ are near to the exposing portions of the two groups of the conductive terminals 20′, when the metal scraps are fallen off on the exposing portions of the conductive terminals 20′, the conductive terminals 20′ are easily caused to be electrically connected with the two docking boards 34′, so that the conventional electrical connector 100′ causes a short circuit.
