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

[0039] The following will combine Figure 1-Figure 15 The technical solution and technical principle of Embodiment 1 of the present application are introduced in detail.

[0040] 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 second terminal group 70. The metal middle plate 40 is formed on the integral first insulator 60, and the second insulator 80 formed on the second terminal group 70 (such as Figure 12 shown), the third insulator 90 formed by forming the first insulator 60 and the second insulator 80 as a whole, the grounding member 30 sleeved on the third insulator 90, and the third insulator 90 surrounding the third The metal shell 10 outside the insulator 90 and the fourth insulator 20 integrally formed at the rear end of the...

Embodiment 2

[0063] see Figure 16 , Figure 17Compared with the first embodiment, the second embodiment of the present application shown is different from the second embodiment in that: the strip-shaped hole 42 on the metal middle plate 40 is penetrated in the insertion direction, so that the metal middle plate The 40-fold division is divided into a completely independent middle body part 41b and two side body parts 41a. At this time, the front ends of the first and second power terminals 50b, 70b do not need to be provided with groove structures, and there is no risk that the first and second power terminals 50b, 70b are too close to the metal middle plate 40 .

[0064] But at this time, what needs to be changed is that during the stamping process of the metal middle plate 40, the middle body part 41b and the two side body parts 41a are separately connected to the front strip of the metal middle plate 40 48 can solve the problem of strip connection caused by the separation of the midd...

Embodiment 3

[0066] see Figure 18 to Figure 20 Compared with the first embodiment, the third embodiment of the present application shown is different from the third embodiment in that: the front connecting portion 44 of the strip hole 42 of the metal middle plate 40 is cut off, and only the rear connecting portion 43 is reserved. And the rear end connecting portion 43 does not need to be thinned to form a concave portion.

[0067] The first power terminal 50b is bent upwards 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 upwardly bent portion 57 and the parallel extending portion 58 are located on the holding portion 52 . Thus, the distance between the parallel extending portion 58 and the rear connecting portion 43 will be increased, and the upper part of the holdi...

Abstract

A large-current USB Type C socket comprises a metal medium plate which is provided with a body part, a first terminal group and a second terminal group which are respectively arranged at the upper and lower sides of the metal medium plate and are symmetrical, and an insulating body which integrally molds the first and second terminal groups and the metal medium plate. The first and second terminal groups comprise two first grounding terminals and two second grounding terminals at the outmost side, a plurality of first signal terminals and two first power terminals between the two first grounding terminals, and a plurality of second signal terminals and two second power terminals between the two second grounding terminals, wherein the first and second power terminals are thicker than the first and second signal terminals. The metal medium plate is provided with strip holes in positions corresponding to the first and second power terminals. The large-current USB Type C socket of the application can effectively support large-current charging.

Description

technical field [0001] The present application relates to an input and output electrical connector, especially a high-current USB Type C socket. 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 into account both size and performance, and is suitable for 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 two sets of conductive terminals, limited by the size, the distance between the two sets of conductive terminals and the metal middle plate is very small, and the terminal thickness is 0.12mm Next, the distance between the te...
