Finally, carry out the 4th injection mo(u)lding at described metal shell 10 and described 3rd insulator end after 90s and form the 4th
Insulator 20, described 4th insulator 20 is combined fixing with the pore structure 14 of described metal shell 10.
Embodiment two
Referring to the application the second embodiment shown in Figure 11, Figure 12, compared to embodiment one, the difference of embodiment two exists
In: according to the standard criterion of USB-IF association, described first, second ground terminal 50a, 70a and first, second power supply terminal
The length of 50b, 70b front end is more than described first, second signal terminal 50c, the length of 70c front end, length difference away from for 0.5mm,
So, cause described metal medium plate 40 must be cut completely through two independent parts of formation by embodiment one.
In embodiment two, by described first, second ground terminal 50a, 70a and first, second power supply terminal 50b, before 70b
The length that end extends is reduced to the only described first, second signal terminal 50c of ratio, the state of the long 0.2mm of 70c, then by described metal
The front end of middle plate 40 arranges connecting portion 47, two metal medium plate 40 structures independent in embodiment one is connected as a single entity, to strengthen
The intensity of described metal medium plate.The corresponding described first, second power supply terminal 50b in the inner side of the most described connecting portion 47,70b position
Place is provided with the relief portion 48 of depression to prevent described first, second power supply terminal 50b, the end of 70b from described connecting portion too close to
And produce risk.
Compared to prior art, the positive anti-plug USB socket of the application is by the terminal by first, second terminal group 50,70
Thickness thickeies to reduce impedance, and then reduces the temperature-rise effect of terminal, meanwhile, for ensureing described first, second terminal group 50,70
Will not cause because thickness increases and the short circuit of described metal medium plate 40, by described first, second signal terminal 50c, 70c with described
First, second power supply terminal 50b, the metal medium plate 40 between 70b excises, and makes described metal medium plate 40 exist only in described
One, the second ground terminal 50a, between 70a, to ensure to cause producing between terminal short circuit because of the increase of terminal thickness
Problem.
