The reinforcing plate 45 connects the connecting plate 121 and the two side plates 124.

[0080] The two rows of terminals 20 are 7 in the upper row and 5 in the lower row. Each terminal 20 is a metal plate sheet with an extension portion 21 and a fixing portion 22 formed by stamping and bending the plate surface. The two rows of terminals 20 are respectively assembled and fixed to a row of terminal slots 14 of the upper and lower base bodies 101 and 102 in the upper and lower directions.

At this time, the fixed portion 22 of each terminal 20 is subjected to pressure to be flush with the terminal groove 14, so that the middle section abutment point 211 of the extension portion 21 is pressed tightly against the bottom surface of the terminal groove 14 of the connecting plate 121. In this way, the two rows of terminals 20 can use the middle section abutment point 211 as a reference to make the contact portion 24 protrude from the connecting surface 12 with the same protrusion height.

[0082] The contact portions 24 of the two rows of terminals are arranged according to the contact circuit number of the USB TYPE-C, but not in a continuous arrangement of the contact circuit number, so they are arranged at unequal intervals. In terms of design, the upper and lower rows of terminals 20 are arranged to make the best use of the area of ​​the joint surface 19 of the upper and lower seats 101 and 102 to allow the fixing portion 22 and the pin 23 to have a wider board surface.

The groove 18 of the upper base body 101 is assembled with a conductive sheet 28. The abutment points 281 bent and protruding at both ends of the conductive sheet 28 are respectively connected to the fixed portions 22 of A4 and A9. In this way, the power terminals A4 and A9, B4 and B9 are electrically connected. Only the pin 23 of A9 extends backward to the rear section 17 of the platform to form a standard connection pin position. The pins 23 of the remaining A4, B4 and B9 are shorter and are only located at the front section of the platform.
