The electrical connector described in item 3 of the patent application, wherein the end surface of each of the spacers is flush with the second surface of the substrate, and a plurality of connecting portions extend rearward from the rear end of the metal shell, and each of the The connecting part at least includes a first claw part, and the first claw part clamps the receiving part and the protruding part. The electrical connector as claimed in item 2 of the patent application, wherein the metal shell includes a first plate body and a second plate opposite to the first plate body and buckled with the first plate body. body, a receiving space for storing the insulating body is formed between the first plate body part and the second plate body part, and the rear ends of the first plate body part and the second plate body part both extend rearward There are a plurality of connecting parts. The connecting parts of the first plate body part and the second plate body part are spaced apart. Each of the connecting parts includes at least a second claw part, and the second claw part is clamped on the plurality of cables. The shielding layer includes a convex portion that presses against the contact portion of the ground terminal of the plurality of conductive terminals. As in the electrical connector described in Item 5 of the patent application, the shielding shell includes a frame surrounding the mating protrusion and a grounding portion formed by bending at the lower edge of the frame. The ground portion of the shielding case is exposed on the first surface of the substrate, and both edges of the first plate portion are pressed against the ground portion of the shielding case. The electrical connector as claimed in Item 5 of the patent application, wherein the first plate body part includes a first part located at the front end and a second part located at the rear end of the first part, and the first part has the opening. frame member, the edge of the first part is pressed against the Shielding the grounding portion of the housing, the second portion includes a strip portion and an extension portion bent and extended from both sides of the strip portion. The extension portion and the first portion are entirely located on the same horizontal plane, so The plurality of convex portions are located on the strip portion, and the second plate body portion includes a crimping portion formed by bending a flat plate portion from an edge of the flat plate portion toward the first plate body portion, and the crimping portion clamps The edge and extension of the first part. The electrical connector as claimed in claim 5 of the patent application, wherein the connecting portion of the first plate body part and the second plate body part further includes a third claw part, and the cable further includes a shielding layer wrapped around the The outer insulation layer, the shielding layer and the outer insulation layer of the cable are located outside the metal shell, and the third claw portion clamps the outer insulation layer. The electrical connector as described in item 2 of the patent application, wherein the plurality of conductive terminals are arranged side by side and include at least two signal terminals and two ground terminals located between the at least two signal terminals, and the at least two A signal terminal is located at the outermost two sides of the plurality of conductive terminals. The contact portion of the plurality of conductive terminals defines a plate-shaped first contact portion of the signal terminal, and has a plate-shaped portion and a plate-shaped first contact portion. The second contact portion of the contact piece is formed by tearing, the holding portions of the two ground terminals located between the at least two signal terminals are jointly connected to the plate-shaped portion of the second contact portion, and the contact piece is exposed on the second surface of the substrate. The electrical connector as described in item 9 of the patent application, wherein the plurality of conductive terminals includes four signal terminals and six ground terminals, and two signal terminals among the four signal terminals are located between the plurality of conductive terminals. On the outermost sides, the other two signal terminals are located between the two signal terminals on the outermost sides. The six ground terminals are divided into three groups of two ground terminals. Each group of ground terminals is located adjacent to each other. Between the two signal terminals, the plurality of cables are four cables respectively corresponding to the four signal terminals.
