In specific implementation process, in step 3, the material strip finally retained is not limited to material strip 56a and secondary signal end after the first signal terminal
Sub-76a, can be any one in material strip 55a and secondary signal after material strip 56a and the first power supply terminal after the first signal terminal
The combination of any one in material strip 75a after material strip 76a and second source terminal after terminal.After two kinds of combination in material strip at least
Need to by material strip bending after one of which so that after two kinds the position of material strip do not produce conflict.
Embodiment two
Referring to the application the second embodiment shown in Figure 16, Figure 17, compared to embodiment one, the difference of embodiment two is:
By the most through for the strip hole 42 on described metal medium plate 40, make described metal medium plate 40 be divided into again and be completely independent
Intermediate body portions 41b and two both sides main part 41a.Now, described first, second power supply terminal 50b, the front end of 70b without
Need to arrange groove structure again, the most there is not described first, second power supply terminal 50b, 70b is the nearest apart from described metal medium plate 40
Risk.
But at this time, it may be necessary to change, described metal medium plate 40 in punching course forming process, described intermediate body portions
41b and two both sides main part 41a is individually connected on the front material strip 48 of described metal medium plate 40 to solve middle master
Body 41b separates, with both sides main part 41a, the material strip connectivity problem caused.
Embodiment three
Referring to the application the 3rd embodiment shown in Figure 18 to Figure 20, compared to first embodiment, the difference of embodiment three exists
In: the front end connecting portion 44 in the strip hole 42 of metal medium plate 40 is excised, only retains rear connecting portion 43, and described rear end connects
Portion 43 is without thinning formation depressed part.
And described first power supply terminal 50b be positioned at use upwards bending at described rear connecting portion 43 after extending in parallel
Mode, the anterior position that described first power supply terminal 50b is positioned at described rear connecting portion 43 forms upwards bending part 57, and from
The parallel extensions 58 extended after described upwards bending part 57.Described upwards bending part 57 is positioned at institute with described parallel extensions 58
State on holding parts 52.Thus, described parallel extensions 58 will strengthen apart from the distance of described rear connecting portion 43, and described solid
Hold and all can be coated by an insulating material above portion 52, the condition extended after possessing bending.
And described second source terminal 70b downward bending, nothing when being positioned at described rear connecting portion 43 position
The structure design extended after need to carrying out bending.But in actual implementation process, if described second source terminal 70b needs to cross institute
State rear connecting portion 43, then can re-extend after downward bending in the way of employing is identical with the first power supply terminal 50b.
Compared to prior art, the big electric current USB Type c-type socket of the application is by by described first, second power supply
The terminal thickness of terminal 50b, 70b thickeies with reduction impedance enhancing electric current by property, simultaneously by corresponding for described metal medium plate 40 institute
Stating first, second power supply terminal 50b, 70b position cuts out in the strip hole 42 of terminal bearing of trend to avoid described thickening
First, second power supply terminal 50b, 70b and described metal medium plate cause the problem of short circuit to occur.
The terminal thickness of first, second terminal group 50,70 thickeies to reduce impedance, and then reduces the temperature-rise effect of terminal,
Meanwhile, for ensureing that 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 and described first, second power supply terminal 50b, the metal medium plate 40 between 70b
Excision, makes described metal medium plate 40 exist only in described first, second ground terminal 50a, between 70a, and will not be because of end with guarantee
The increase of sub-thickness and the problem that causes producing short circuit between terminal.
