The reinforcement plate 45 is connected by the connecting plate 121 and the two side plates 124.

[0183] 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. The fixing portion 22 is provided with a fixing portion 221 to form a front and rear limit fixing with the terminal slot 14 of the base 11, and the plate surface of the fixing portion 22 is substantially flush with the joint surface 19.

The rear end of the fixing portion 22 of the partial terminal 20 is integrally connected to a pin 23 extending to the groove 172 of the platform 17.

[0184] like Fig. 9 As shown, when the two rows of terminals 20 are assembled and fixed to the row of terminal slots 14 of the upper and lower base bodies 101 and 102 in the vertical direction, the fixing portion 22 of each terminal 20 has an overflow pressure and protrudes obliquely from the terminal slot 14, as shown in FIG. Figure 8 As shown, after the upper and lower base bodies 101, 102 are joined and the metal shell 30 is sleeved and positioned, the fixed portion 22 of each terminal 20 is pressed flat against the joint surfaces 19 of the upper and lower base bodies 101, 102 and is fixed in a limited position in the up and down 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.

[0185] 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.
