[0030] Reference Figures 1-6 The image shown is a preferred embodiment of the present invention.
[0031] The high-current dual-channel high-speed Type-C connector provided by this utility model includes a terminal plastic shell assembly 100 and a main shell 200. The main shell 200 surrounds and forms a shell cavity with openings on both sides. The front end of the terminal plastic shell assembly 100 is embedded in the shell cavity, and the main shell 200 is fixedly connected to the front end of the terminal plastic shell assembly 100 to form a Type-C interface.
[0032] The terminal housing assembly 100 includes an upper row of terminal housing assemblies 110 and a lower row of terminal housing assemblies 120 arranged vertically. The upper row of terminal housing assemblies 110 includes an upper row of first terminal groups 111 made of a first thickness material and an upper row of second terminal groups 112 made of a second thickness material. The upper row of first terminal groups 111 and upper row of second terminal groups 112 are arranged in a row. The upper row of first terminal groups 111 includes an upper row of VBUS terminals, an upper row of GND terminals, and an upper row of CC terminals.
[0033] The lower terminal housing assembly 120 includes a lower first terminal group 121 with a first thickness and a lower second terminal group 122 with a second thickness. The lower first terminal group 121 and the lower second terminal group 122 are arranged in a row. The lower first terminal group 121 includes a lower VBUS terminal, a lower GND terminal and a lower CC terminal. The first thickness is greater than the second thickness.
[0034] The aforementioned upper row terminals VBUS, lower row terminals VBUS, upper row terminals GND, lower row terminals GND, upper row terminals CC, and lower row terminals CC use a first thickness of material, while the other pin terminals (upper row second terminal group 112 and lower row second terminal group 122) use a second thickness of material. This allows for a thicker material for current-carrying terminals and a thinner material for the upper and lower row second terminal groups of communication terminals, enabling high-speed signal transmission under high current conditions while reducing electromagnetic interference between pins.
[0035] Specifically, the other pin terminals (second terminal group 112 in the upper row and second terminal group 122 in the lower row) include: SSTxp1, SSTxn1, Dp1, Dp2, SBU1, SBU2, SSPRxp1, SSPRxn1, SSPRxn2, SSPRxp2, SSTxn2, SSTxp2, Dn1, and Dn2 pin terminals. These are signal-type pin terminals, enabling dual-channel high-speed transmission.
[0036] Reference Figure 2 As shown, the terminals with greater thickness are the upper first terminal group 111 and the lower first terminal group 121. The terminals with less thickness are the upper second terminal group 112 and the lower second terminal group 122.
[0037] Reference Figure 2 As shown, along the left-to-right direction, the terminals on the upper row of terminal housing assembly 110 include: GND, SSPRxp2, SSPRxn2, VBUS, SBU1, Dn1, Dp1, CC1, VBUS, SSTxn1, SSTxp1, and GND terminals.
[0038] Reference Figure 2 As shown, along the left-to-right direction, the terminals on the lower row of terminal housing assembly 120 include: GND, SSTxp2, SSTxn2, VBUS, CC2, Dp2, Dn2, SBU2, VBUS, SSPRxn1, SSPRxp1, and GND terminals.
[0039] In a preferred embodiment, the rear of the terminal housing assembly 100 arches upward, giving the terminal housing assembly 100 a Z-shaped appearance. This effectively saves space on the back of the molded product.
[0040] In this embodiment, the front ends of the upper row of VBUS terminals and the lower row of VBUS terminals are respectively inserted into the housing cavity to form a front section, and the front section has an inwardly recessed groove.
[0041] The rear end of the main housing 200 is formed by stretching to create a rolled edge structure that curls towards the housing cavity. The rolled edge structure has a surrounding enclosure wall 210. The front end of the terminal housing assembly 100 passes through the enclosure wall 210 and is fixedly connected to it. A groove is correspondingly provided at the position of the enclosure wall 210. In this way, the groove design increases the distance between the power terminal and the main housing 200, avoiding the risk of short circuit between the terminal and the main housing under withstand voltage.
[0042] The main housing 200 adopts a stretched integrated structure, resulting in high overall structural strength. Furthermore, the enclosing wall 210 and the side walls of the main housing 200 are sealed, providing shielding against external signal interference.
[0043] The terminal housing assembly 100 also includes an injection-molded outer peripheral housing 130, which wraps around the upper row of terminal housing assemblies 110 and the lower row of terminal housing assemblies 120. The space between the enclosing wall 210 and the groove is fixedly filled with the outer peripheral housing 130. In this way, the injection-molded outer peripheral housing 130 achieves isolation, avoids short circuits, and also achieves better fixation.
[0044] The upper row terminal housing assembly 110 has multiple vertically penetrating upper row through holes 113 at its rear, and the lower row terminal housing assembly 120 has multiple vertically penetrating lower row through holes at its rear. The upper row through holes 113 and the lower row through holes partially overlap and are connected. The outer peripheral housing 130 fills the multiple upper row through holes 113 and the multiple lower row through holes. This effectively increases the bonding strength between the upper row terminal housing assembly 110 and the lower row terminal housing assembly 120.
[0045] In a preferred embodiment, an outer shell 300 is fastened to the outer periphery of the main housing 200. The outer shell 300 is fixedly connected to the main housing 200 by riveting. The front part of the outer shell 300 is connected to the main housing 200, and the rear part of the outer shell 300 wraps around the outer periphery of the terminal plastic shell assembly 100. The front and rear parts of the outer shell 300 are arranged in a vertical Z-shape. In this way, the design of the outer shell 300 protects the entire terminal plastic shell assembly 100 and fixes the main housing 200, thus providing protection.
[0046] The rear end of the housing 300 has a downwardly extending baffle 310, which is spaced apart from the rear end of the terminal housing assembly 100. In this way, by making a baffle 310 at the rear of the housing 300, a metal shielding layer is provided for the solder feet of each terminal, reducing strong interference from high-speed signals.
[0047] Specifically, the upper row terminal housing assembly 110 also includes an upper row of housing components, which fix the upper row first terminal group 111 and the upper row second terminal group 112. The lower row terminal housing assembly 120 also includes a lower row of housing components, which fix the lower row first terminal group 121 and the lower row second terminal group 122.
[0048] The upper row of first terminal group 111 and upper row of second terminal group 112 are arranged in a row to form an upper row of terminals, and the lower row of first terminal group 121 and lower row of second terminal group 122 are arranged in a row to form a lower row of terminals. The upper row of terminals and the lower row of terminals are arranged vertically at intervals, and an upper row of plastic shell components and a lower row of plastic shell components are provided between the upper row of terminals and the lower row of terminals. In this way, the upper row of terminal plastic shell assembly 110, the lower row of terminal plastic shell assembly 120, and the terminal plastic shell assembly 100 are formed by injection molding, which are divided into separate processes to facilitate the subsequent three injection molding processes to form the terminal plastic shell assembly 100.
[0049] Preferably, the first thickness is 0.25 mm and the second thickness is 0.10 mm.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
