Problems solved by technology

[0003] The upper and lower two groups of conductive terminals respectively include a pair of ground terminals located on the outermost side and a pair of power terminals located in the middle. At present, in the case of realizing fast charging, the ground terminals and power terminals are required to allow a large current to pass through, but adding Thickening the power terminals will easily lead to a short circuit with the metal middle plate, while widening the power terminals is limited by the small spacing between terminals, making it difficult to effectively realize the passage of large currents

Embodiment 1

[0045] The following will combine Figure 1-Figure 15 The technical solution and technical principle of the first embodiment of this application are introduced in detail.

[0046] See Figure 1 to Figure 4 As shown, the high-current USB Type C socket of the present application includes a metal middle plate 40, a first terminal group 50 located on the upper and lower sides of the metal middle plate 40, a second terminal group 70, and the first terminal group 50 and The metal middle plate 40 is formed into an integrated first insulator 60, and a second insulator 80 formed on the second terminal set 70 (such as Picture 12 As shown), a third insulator 90 formed by forming the first insulator 60 and the second insulator 80 into a whole, a grounding member 30 sleeved on the third insulator 90, and surrounded by the third insulator The metal shell 10 outside the insulator 90 and the fourth insulator 20 integrally formed at the rear end of the metal shell 10 to eliminate the gap between ...

Embodiment 2

[0069] See Figure 16 , Figure 17 Compared with the first embodiment, the second embodiment shown in the second embodiment of the present application differs in that: the strip hole 42 on the metal middle plate 40 is penetrated in the insertion direction, so that the metal middle plate It is divided by 40 times into a completely independent middle main body 41b and two side main bodies 41a. At this time, the front ends of the first and second power terminals 50b, 70b do not need to be provided with a groove structure, and there is no risk that the first and second power terminals 50b, 70b are too close to the metal middle plate 40 .

[0070] But at this time, what needs to be changed is that during the forming process of the metal middle plate 40, the middle main body portion 41b and the two sides of the main body 41a are separately connected to the front strip of the metal middle plate 40. 48 can solve the problem of connecting the material belt caused by the separation of the...

Embodiment 3

[0072] See Figure 18 to Figure 20 Compared with the first embodiment, the third embodiment shown in the present application differs from the first embodiment in that the front end connecting portion 44 of the strip hole 42 of the metal middle plate 40 is cut off, and only the rear end connecting portion 43 is retained. The rear connecting portion 43 does not need to be thinned to form a recessed portion.

[0073] The first power terminal 50b is bent upward at the rear connecting portion 43 and then extends in parallel. The first power terminal 50b is located in front of the rear connecting portion 43 to form an upward fold. A bent portion 57 and a parallel extending portion 58 extending from the upward bent portion 57. The upward bending portion 57 and the parallel extending portion 58 are located on the holding portion 52. As a result, the distance between the parallel extending portion 58 and the rear connecting portion 43 will be increased, and the upper portion of the hold...

Abstract

The invention relates to a high-current Type C socket, which comprises a metal medium plate, a first terminal group, a second terminal group and an insulating body, wherein the metal medium plate is provided with a main body portion, the first terminal group and the second terminal group are respectively located at the upper side and the lower side of the metal medium plate in a symmetrical manner, and the first terminal group, the second terminal group and the metal medium plate are molded into an integral whole by the insulating body. The first terminal group and the second terminal group respectively comprise two first grounding terminals, two second grounding terminals, a plurality of first signal terminals, two first power supply terminals, a plurality of second signal terminals and two second power supply terminals, wherein the two first grounding terminals and the two second grounding terminals are located at the outmost side, the plurality of first signal terminals and the two first power supply terminals are located between the two first grounding terminals, the plurality of second signal terminals and the two second power supply terminals are located between the two second grounding terminals, the thickness of the first power supply terminals and the second power supply terminals is greater than the thickness of the first signal terminals and the second signal terminals, and the main body portion of the metal medium plate is provided with strip-shaped holes at the positions corresponding to the first power supply terminals and the second power supply terminals. The high-current USB Type C socket can effectively support high-current charging.

Description

Technical field [0001] The present application relates to an input / output type electrical connector, in particular to a high-current USB Type C socket and a manufacturing method thereof. Background technique [0002] The USB3.1 Type C interface is a new interface standard launched by the USB-IF Association in 2014. This standard takes both size and performance into consideration, adapting to applications on smart terminals, but it is not backward compatible. It generally includes a metal middle plate, two sets of conductive terminals arranged on the upper and lower sides of the metal middle plate, and an insulating material that holds the metal middle plate and the conductive terminals as a whole. The metal middle plate is used to shield the high-frequency interference of the upper and lower sets of conductive terminals, limited to the size limit, the distance between the two sets of conductive terminals and the metal middle plate is very small, in the case of a terminal thicknes...
