[0010] As shown in FIGS. 1 and 9, the ultra-thin waterproof structure of the USB Type-C female socket includes an iron outer shell 1, a female socket body 2, and a UV adhesive sealing ring 3. Among them, the iron outer shell 1 covers the female socket body 2. The iron outer shell 1 includes side plates 11, a top surface 12, and a side surface 13. The top surface 12 is a rectangular surface. The side plate 11 has a rectangular surface. The side surface 13 is a square surface, and there are at least two such side surfaces 13. The side surfaces 13 are respectively arranged at both ends of the top surface 12. The connection angles between both ends of the top surface 12 and the side plate 11 are arc angles. The upper side of the side plate 11 is connected and fixed to one side of the top surface 12. Both side edges of the side plate 11 are respectively connected and fixed to the side surface 13. Thus, the side plate 11, the top surface 12, and the side surface 13 are combined to form an internal space 14 with three sides. Welding platforms 141 are respectively provided at both ends of the internal space 14.

[0011] On both of the side surfaces 13, fixing screw hole plates 15 perpendicular to the side surfaces 13 are respectively provided. The fixing screw hole plates 15 are square in shape. The width of the fixing screw hole plates 15 is narrower than the width of the side surfaces 13. One side of the fixing screw hole plates 15 is parallel to one side of the side surfaces 13. Both corners of the fixing screw hole plates 15 are arc-shaped. An oblong elliptical hole 111 is provided at the central part of the side plate 11. A convex platform 112 is provided on its outer edge. There is a groove 113 that fits exactly to the edge on the outer edge of the convex platform 112. The groove 113 is formed 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 pasted and fixed in the groove 113. This UV adhesive sealing ring 3 is used to form an annular sealing and waterproof structure when inserted into the cabinet panel. The female seat body 2 is provided with a protruding insertion plate 21. A fitting platform 211 is provided at the bottom end of the insertion plate 21. The fitting platform 211 coincides with the inside of the oblong elliptical hole 111. The insertion plate 21 is inserted and extended from the oblong elliptical hole 111. The fitting platform 211 at the bottom end of the insertion plate 21 is firmly fixed inside the oblong elliptical hole 111.

[0012] Welding plates 22 are provided at both ends of the female socket body 2. The welding plates 22 are square in planar shape, and the width of the welding plates 22 is narrower than the width of both ends of the female socket body 2. The welding plates 22 are used to fix the female socket body 2 to the welding platform 141 in the inner cavity by spot welding. The iron outer shell 1 is manufactured by powder metallurgy and die-casting processes, and the groove 113 is integrally formed when the iron outer shell 1 is formed. A screw hole 151 is provided at the center of the fixed screw hole plate 15. The screw hole 151 penetrates the fixed screw hole plate 15 and is used to fix the connector. Threads 152 are provided inside the screw hole 151, and the threads 152 are reverse threads. There are no threads inside the screw hole 151, and the screw hole 151 is used to facilitate fixation during assembly. Welding points 221 are provided on the welding plates 22. The welding points 221 fix the female socket body 2 and provide the strength of the female socket body 2. A terminal structure 23 is provided on the female socket body 2. The terminal structure 23 is fixed to the female socket body 2. The terminal structure includes a terminal patch board leg structure, and this terminal patch board leg structure is a spring piece type structure. The fixing method of the terminal patch board leg is a pressure welding method. The terminal structure 23 further includes terminals 231. The terminals 231 are made of a highly conductive material, and their thickness is 0.10 mm to 0.30 mm. The UV adhesive sealing ring 3 is a UV drop adhesive material. Half of the UV adhesive sealing ring 3 is fixed in the groove 113, and the other half is exposed outside the groove 113. The optimal height of the iron outer shell 1 is 1 to 4 mm, and the optimal length from one side of the upper surface 12 of the iron outer shell 1 to the top end of the insertion plate 21 is 5 to 10 mm.

[0013] As shown in FIGS. 1 and 9, in a specific embodiment of the ultra-thin waterproof structure of the USB Type-C female socket of the present invention, a groove 113 is formed around the outer edge of the oblong elliptical hole 111 provided on the side plate 11 of the iron outer shell 1, and the UV drop adhesive of the UV adhesive sealing ring 3 is applied on the groove 113. Next, the female socket body 2 is fixed to the iron outer shell 1 by spot welding using the welding points 221 of the welding plate 22 to strengthen the overall product strength, and the terminal structure 23 is directly fixed to the female socket body 2 by a pressure welding method. The UV adhesive is dropped on the groove 113 to form the UV adhesive sealing ring 3. Since the adhesive is in a liquid state, it is difficult to fix its shape in the normal state. However, the groove 113 is used to fix the UV adhesive to create a good fixing state before the UV adhesive solidifies. After solidification, it provides a certain adhesive force and enhances the bonding force of the adhesive. Thereby, a special waterproof structure is formed, the adhesiveness and fixability of the UV adhesive before and after solidification are improved, the waterproof sealing property is strengthened, and a reliable waterproof effect is provided.

[0014] As shown in FIG. 9, when the ultra-thin waterproof structure of the USB Type-C female socket of the present invention is actually used, when the insertion plate 21 is inserted into the chassis panel and the side plate 2 of the iron outer shell 1 contacts the chassis panel, the UV adhesive sealing ring 3 closely contacts the top of the hypotenuse of the contact surface of the chassis panel to form an annular sealed waterproof structure. Thereby, the waterproof sealing property of the whole product is realized and the waterproof reliability is provided. The iron outer shell 1 is manufactured by powder metallurgy and die-casting processes, and the iron outer shell 1 can be made to correspond to different heights of the product. For example, products of different heights are possible from a 3.40 mm plate to a -3.40 mm sunken plate. Threads are added inside the screw holes at both ends of the iron outer shell 1. By using reverse threads, two options of with screw and without screw are provided as options when assembling screws into the screw holes, which simplifies the assembly work and makes it easier for customers to use and assemble the product. By spot welding at both ends of the female socket body 2, the female socket body 2 is fixed, providing the strength of the whole product and also fulfilling the positioning function. The terminal structure 23 has a spring piece type structure, and its connection with the female socket body 2 is a press-fit type structure. Different from the conventional SMT (Surface Mount Technology) soldering, the replacement of terminals can be done simply and quickly. Also, the defective rate by the SMT method is reduced. The terminal 231 is made of a high-conductivity material, and its material thickness is 0.10 mm to 0.30 mm. Terminals of different thicknesses are used for the synchronous signal terminals (TXRX Pin) and the power supply terminals (VBUS & GND Pin), and it can satisfy the requirements of high frequency and large current simultaneously.

[0015] The whole product can be made thinner and shorter, and the thickness from the insertion plate 21 at one end to the edge of the iron outer shell 1 can reach 5 to 10 mm. The height of the iron outer shell 1 can reach 1 to 4 mm. From common technical knowledge, it can be seen that this technical solution can be realized by implementation solutions that do not deviate from its spiritual essence and necessary features. Therefore, the above-disclosed embodiments are merely examples and not the only ones. All changes within the scope of this invention or within the scope equivalent to this invention are included in the utility model defined by this invention.
