The specific embodiment of the novel electrical connector assembly will be described in detail below with reference to the drawings.

Referring to the first to fourth figures, the novel electrical connector assembly 100 includes a plug connector 10 and a receptacle connector 50. The plug connector 10 is connected to a cable 201, and the receptacle connector is mounted on a printed circuit board. 202. The plug connector 10 includes an insulative housing 12, a plurality of conductive terminals 16 disposed on the insulative housing 12, and a shield housing 20. The insulative housing has a docking zone 14 at the front end, and the electrically conductive terminal 16 includes a contact portion 18 that is exposed in the docking zone 14. The shield housing 20 surrounds the docking zone 14 to form a plug port 22 for insertion of the receptacle connector 50, the plug port having a plugging direction. Viewed from the docking direction, the shield housing 20 is generally rectangular in cross-section and includes two opposing long sides 24 and opposite short sides 26 that are connected to each other and perpendicular to each other and form a corner 27. The lower/first long side 24b is formed with inclined sides 28 at its two corners 27 connected to the short sides 26a, 26b, respectively, and the upper/second long side 24a forms a recessed portion 30 projecting toward the plug cavity side at the center thereof. The two sides of the recessed area remain as side areas 34, and the side areas 34 are symmetrically distributed on both sides of the recessed area 30. The second long side 24 is closely attached to the outer wall surface of the docking area 14, and the contact portion 18 of the conductive terminal is arranged on the inner wall surface of the docking area. The upper long side 24a is provided with a locking arm 32 at the side area 34 on both sides of the recessed area, and the end of the locking arm protrudes from the upper surface of the side area 34. From the perspective of the top view, the locking arm 32 falls within the range of the inclined side 28, and the conductive terminal 12 is located between the inner sides of the two inclined sides 28, so as to minimize the number of terminals of the plug connector, and at the same time, the conductive terminal The arrangement direction is beyond the sides of the recessed area 30.

The receptacle connector 50 is then surrounded by a shield housing 60. The upper long side 64a of the shield housing 60 is provided with a recessed area 70, the front edge of which is provided with a leading edge 76 which is aligned with the recessed area. In the process in which the plug connector 70 is inserted into the receptacle connector 50, the leading edge 76 is inserted into the recessed portion 30 for guiding, and is shielded after the recessed portion 70 is fully inserted into the recessed portion 30 of the plug connector.

Referring to the fifth and sixth figures, the socket connector of the second embodiment is shown. The structure of the socket connector is substantially the same as that of the first embodiment except for the leading edge and the light guiding tube 80. The socket connector can be inserted into the plug connector of the first embodiment, so the socket connector will be described in detail herein, and the same reference numerals are used for the same structure as the first embodiment. The socket connector 50 includes an insulative housing 52, a plurality of conductive terminals 56 disposed on the insulative housing, and a shield housing 60. The insulative housing has a forward abutment tab 54 that includes a contact portion 58 that is exposed to the mating tongue 54. The shield housing 60 surrounds the mating tongue 54 to collectively form a receptacle opening 62 for insertion of the plug connector. The shield housing 60 of the receptacle connector has a contour that is substantially similar to the shield housing 20 of the plug connector. Viewed from the docking direction, the shield housing 60 includes two opposite long sides 64 and opposite short sides 66 that are connected to each other and perpendicular to each other. The lower side long side 64b forms a slanted edge 68 at its two corners, and the upper side long side 64a forms a recessed area 70 protruding toward the socket opening at the center thereof, so that the shielding case 20 of the plug connector can be tightly received, The butt tongue 54 is held between the docking zone 14 and the lower long side 24a of the plug connector 10. The upper long side 64a is provided with a locking hole 72 in the side area 74 on both sides of the recessed area. Referring to the first and second figures, the front edge of the shield housing 60 of the receptacle connector is provided with a guiding edge 76 which is aligned with the recessed area for guiding and shielding. Referring to the fifth and sixth figures, the shielding shell is not provided with a guiding edge, and the recessed area is provided with a pair of light guiding tubes 80, and the light guiding tube 80 extends along the recessed area, together with the outer side.

Referring to the seventh and eighth figures, the plug connector 10' has a docking cavity 90' in the middle, and the insulative housing has two opposite and separated first butt regions 14a and 14b, and the conductive terminals respectively There are contact portions 18a', 18b' arranged in the first and second docking regions. In the vertical direction, the two rows of conductive terminals are respectively located on both sides of the docking cavity. The two opposite long sides of the shielding case are closely attached to the outer wall surfaces of the first and second docking areas, respectively, and the contact portions of the conductive terminals are arranged on the inner wall of the docking area.
