[0029] The following is in conjunction with the appendix Figure 1 and 9 The present invention will be described in detail with reference to specific embodiments, but this is not intended to limit the present invention. Example

[0030] As attached Figure 1 and 9 As shown, a novel ultra-thin waterproof structure for a USB TYPE-C female connector includes an iron outer shell 1, a female connector body 2, and a UV adhesive sealing ring 3; wherein the iron outer shell 1 covers the female connector body 2;

[0031] The iron outer shell 1 includes a side plate 11, a top surface 12, and side surfaces 13, wherein the top surface 12 is a rectangular surface; the side plate 11 is a rectangular surface; and the side surfaces 13 are square surfaces, wherein there are at least two side surfaces 13; the side surfaces 13 are respectively located at both ends of the top surface 12, and the connection angle between the two ends of the top surface 12 and the side surfaces 11 is an arc angle; the top edge of the side plate 11 is connected and fixed to one side of the top surface 12; the two sides of the side plate 11 are respectively connected and fixed to the two side surfaces 13; wherein the side plate 11, the top surface 12, and the side surfaces 13 are combined to form a three-sided inner cavity 14; the top two ends of the inner cavity 14 are respectively provided with welding stations 141;

[0032] Both sides 13 are provided with fixing screw plate 15 perpendicular to the side 13. The fixing screw plate 15 is square in shape. The width of the fixing screw plate 15 is smaller than the width of the side 13. One side of the fixing screw plate 15 is flush with one side of the side 13. The two corners of the fixing screw plate 15 are arc corners.

[0033] The side plate 11 has a flat oval hole 111 in the middle, and a boss 112 on the outer edge of the flat oval hole 111. The outer edge of the boss 112 has a groove 113 that fits tightly against the edge. The groove 113 is used to fix the UV adhesive sealing ring 3. The UV adhesive sealing ring 3 has adhesiveness and waterproofness. The UV adhesive sealing ring 3 is laid and bonded to the groove 113. The UV adhesive sealing ring 3 is used to form a ring-shaped closed waterproof structure when inserted into the housing panel.

[0034] The female body 2 is provided with a protruding insert plate 21, and the bottom end of the insert plate 21 is provided with a locking platform 211. The locking platform 211 matches the inner side of the flat elliptical hole 111. The insert plate 21 is inserted and extended from the flat elliptical hole 111; the locking platform 211 at the bottom end of the insert plate 21 is locked in the inner side of the flat elliptical hole 111.

[0035] The female connector body 2 has welding plates 22 at both ends. The welding plates 22 are square and flat, and their width is smaller than the width of the female connector body 2 at both ends. The welding plates 22 are used to spot weld the female connector body 2 onto the welding table 141 in the inner cavity. The iron shell 1 is made using powder metallurgy and die casting processes. The groove 113 is integrally formed during the molding of the iron shell 1. The fixing screw hole plate 15 has a screw hole 151 in the middle, which penetrates the fixing screw hole plate 15 and is used to fix it to the connector. The screw hole 151 has a thread 152 on its inner side, which is a reverse pull thread. The screw hole 151 has no thread on its inner side and is used to facilitate assembly and fixation. The welding plates 22 have weld points 221, which are used to fix the female connector body 2 and provide strength to the female connector body 2. The female connector body 2 is provided with a terminal structure 23, which is fixed to the female connector body 2. The terminal structure includes a terminal mounting plate structure, which is a spring-loaded structure, and the terminal mounting plate is fixed by a crimping method. The terminal structure 23 also includes a terminal 231, which is made of a highly conductive material with a thickness of 0.10mm to 0.30mm. The UV adhesive sealing ring 3 is made of UV adhesive material, with half of the UV adhesive sealing ring 3 fixed in the groove 113 and half exposed outside the groove 114. The optimal height of the iron shell 1 is 1 to 4mm, and the optimal length from one side of the top surface 12 of the iron shell 1 to the top of the insert plate 21 is 5 to 10mm.

[0036] As attached Figure 1 and 9 As shown, a novel ultra-thin waterproof structure for a USB Type-C female connector is implemented as follows: A groove 113 is made around the outer edge of the flat oval hole 111 on the side plate 11 of the iron shell 1. UV adhesive of the UV sealing ring 3 is applied to the groove 113. The female connector body 2 is fixed to the iron shell 1 by spot welding using the solder joints 221 on the welding plate 22, thereby enhancing the overall strength of the product. The terminal structure 23 is directly fixed to the female connector body 2 by crimping.

[0037] UV adhesive is applied to the groove 113 to form a UV seal ring 3. Since the adhesive is liquid, it is difficult to fix its shape under normal conditions. The groove 113 is used to fix the UV adhesive, providing a good fixation before the UV adhesive cures into the UV seal ring 3. After curing, it provides a certain degree of adhesion, improving the adhesive's bonding strength. This forms a special waterproof structure. It facilitates adhesion before and after UV adhesive curing, and the fixation of the UV adhesive before curing improves the waterproof sealing performance and provides reliable waterproofing.

[0038] like Figure 9As shown, when the new USB TYPE-C female connector ultra-thin waterproof structure is put into actual use, the plug plate 21 is inserted into the housing panel. When the iron outer shell 1 side plate 2 contacts the housing panel, the UV glue sealing ring 3 just abuts against the top of the inclined edge of the contact surface of the housing panel, forming a tight fit and forming a ring-shaped closed waterproof structure. This achieves the waterproof sealing of the entire product and provides waterproof reliability.

[0039] The metal casing 1 is manufactured using powder metallurgy and die casting processes. It can be made to accommodate products of varying heights, from 3.40mm on the plate to -3.40mm on the countersunk plate. Threads are added to the inner sides of the screw holes at both ends of the metal casing 1, allowing for reverse pull-out. Both threaded and unthreaded options are available, facilitating screw installation onto the connector during assembly and simplifying customer use and assembly. Spot welding at both ends of the female connector body 2 provides structural strength and a limiting function. The terminal structure 23 is a spring-loaded design, connecting to the female connector body 2 via a press-fit structure, unlike ordinary SMT soldering, allowing for quick and easy replacement. This also reduces the defect rate caused by SMT processes. Terminals 231 are made of highly conductive material with thicknesses ranging from 0.10mm to 0.30mm. Different thicknesses are used for the synchronous signal terminals (TXRX Pin) and power terminals (VBUS & GND Pin) to meet both high-frequency and high-current requirements.

[0040] The entire product can be thinner and shorter, with the thickness from the end plate 21 to the edge of the iron shell 1 reaching 5~10mm, and the height of the iron shell 1 reaching 1~4mm.

[0041] As is known from common technical knowledge, this technical solution can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
