However, when the power is transmitted with the external electrical connector, the contact arms 223 of the spacers 22 contact the top surface of the accommodating space 30 of the housing 3, so that a ground loop is formed, i.e. the path and density of ground conduction can be increased, and electromagnetic waves and crosstalk interference generated during signal transmission can be reliably led out.
The upper and lower end surfaces of the mating end 212 of the plurality of terminals 21 are formed with arc-shaped or inclined guide surfaces 2125, so that the connection between the mating end 212 of the insulating base 1 and the tongue plate 12 can be increased by the guide surfaces 2125, and when the plurality of conductive terminals and the plurality of ground terminals of the external electrical connector contact the mating end 212 of the plurality of terminals 21, the mating end 212 can guide the plurality of conductive terminals and the plurality of ground terminals to the upper and lower mating surfaces 2121 by the upper and lower guide surfaces 2125, so as to improve the smoothness of the mating.
Therefore, the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, wherein one side of the base 11 of the insulating base 1 of the present invention is extended with the tongue plate 12, and the insulating base 1 is combined with the plurality of terminals 21 and the spacers 22 of the terminal set 2, wherein the terminal 21 has the base 211 combined in the base 11, and the base 211 has the docking end 212 combined in the tongue plate 12 extended from one side thereof, and the upper and lower sides of the docking end 212 are formed with the docking surfaces 2121 exposed from the upper and lower sides of the tongue plate 12, and the other side of the base 211 is extended downward with at least one connecting end 213 for forming an electrical connection with an external circuit board, and the spacer 22 is internally provided with at least one through hole 221 for inserting the plurality of terminals 21, and the insulating base 1 and the terminal set 2 are covered with the housing 3, because the spacer 22 of the terminal set 2 is made of a metal material, and is formed inside the tongue plate 12 of the insulating base body 1, so that the structural strength of the tongue plate 12 can be improved, the breaking condition of the tongue plate 12 caused by long-time plugging can be reduced, and the service life of the whole body can be prolonged.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
