Description

Technical Field

[0001] This utility model relates to the field of USB TYPE-C connectors, and in particular to a novel waterproof structure for a USB TYPE-C connector female socket that provides better sealing and waterproofing, while also preventing adhesive deterioration. Background Technology

[0002] As application areas continue to expand, the requirements for waterproofing and strength of products are constantly increasing. USB Type-C connectors are mainly used in 5G mobile phones, communication equipment, network equipment, routers, laptops, e-cigarettes, and more. These increasingly diverse applications place ever-higher demands on the waterproofing and strength of connectors. Therefore, the waterproofing structure and stability of existing USB Type-C connectors need to be strengthened. For example, they are difficult to position during panel assembly, prone to over-insertion during insertion, and susceptible to adhesive core delamination, failing to meet the new and higher requirements of next-generation USB Type-C connectors. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel waterproof structure for a USB TYPE-C connector female socket that differs from the common design of combining a rubber sealing ring and a V-shaped groove, adds a baffle for positioning and stopping, and adds a barb for adhesive removal.

[0004] The technical solution provided by this invention is: a novel socket connection structure, comprising: an iron outer shell, an inner iron shell, a rubber core, and a glue sealing ring.

[0005] Specifically, the outer iron shell has a receiving space inside; the receiving space is open at both ends; the receiving space is for assembling the inner iron shell; the inner iron shell has an assembly space; the assembly space is open at both ends, with one end being larger than the other; the rubber core is inserted into the assembly space through the smaller opening, with its tail end protruding outside the assembly space. Side baffles are provided on both sides of the outer iron shell; a fixing plate is provided on the top of the outer iron shell; the edge of the opening at one end of the outer iron shell is bent outward, and the bent part forms a V-shaped groove with the outer wall of the inner iron shell; the glue sealing ring is sealed in the V-shaped groove, and part of the glue sealing ring is exposed in the V-shaped groove; the glue sealing ring is used to seal and waterproof when the product is assembled with the panel; the upper and lower inner walls of the inner iron shell are recessed inward near the small opening, reducing the height of the upper and lower inner walls and forming a stop structure to prevent over-insertion during use. The bottom of the inner iron shell has barbs that bend towards the assembly space on both sides near the small opening; the glue core has a groove near its tail end; when the glue core is inserted into the assembly space, the barbs are locked in the groove to prevent the glue core from coming off.

[0006] In the further optimized design, the side baffle and the iron shell are L-shaped; the side baffle is used for positioning and stopping the panel during assembly.

[0007] In the further optimized design, the side baffle is made by hollowing out and bending the side of the iron shell, and is integrally formed with the iron shell during the forming process.

[0008] In a further optimized design, the fixing plate and the top of the iron shell are L-shaped and integrally formed with the iron shell during molding.

[0009] In a further optimized design, the fixing plate has a screw hole in the middle, which is used for positioning and fixing.

[0010] In a further optimized solution, the adhesive sealing ring material is adhesive, preferably UV adhesive, silicone, epoxy resin adhesive, and underfill adhesive.

[0011] In a further optimized design, the adhesive sealing ring is shaped like a semi-circular head, which is more advantageous for assembling the product with the panel.

[0012] In a further optimized design, the thickness of the adhesive sealing ring before and after the adhesive sealing ring is 0.50 mm to 1.0 mm. This thickness serves to seal against interference between the adhesive sealing ring and the panel during assembly.

[0013] In a further optimized design, the V-shaped groove is used to hold the adhesive when the adhesive sealing ring is applied.

[0014] In a further optimized design, after the inner iron shell is assembled into the receiving space of the outer iron shell, the front end of the inner iron shell is exposed outside the receiving space.

[0015] Compared to previously disclosed technical solutions, the innovative aspect of this novel waterproof USB Type-C connector female socket structure lies in its use of a fixture and a metal shell to apply adhesive and shape it, achieving a sealing and waterproof structure between the USB Type-C connector and the panel. Different fixture specifications and dispensing methods are designed for different structural products to meet various customer needs for different shapes and functions. When using a V-shaped groove for dispensing, the adhesive is supported, and the height of the upper and lower inner walls is reduced at the tail of the inner metal shell, forming a stop structure. This prevents over-insertion and provides a stop. A barbed structure is added to the tail of the inner metal shell, which, after assembling the adhesive core, secures it and prevents the core from slipping back. A baffle plate is added for positioning and stopping, controlling the relative assembly position of the USB Type-C connector and the panel. A bent fixing plate structure with screw holes is added to the outer metal shell for product positioning. This achieves a more sealed and waterproof effect, while also providing a stop and preventing adhesive slippage. Attached Figure Description

Detailed Implementation

[0017] 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

[0018] As attached Figure 1 and 4 As shown, a novel waterproof structure for a USB TYPE-C connector female includes an outer iron shell 1, an inner iron shell 2, a rubber core 3, and a rubber sealing ring 4. The outer iron shell 1 has an internal receiving space with openings at both ends. The receiving space is for assembling the inner iron shell 2 within it. The inner iron shell 2 has an assembly space with openings at both ends, one large and one small. The rubber core 3 is inserted into the assembly space through the smaller opening, with its tail end protruding outside the assembly space. As attached Figure 5 As shown, the iron outer shell 1 has side baffles 11 on both sides; a fixing plate 12 is provided on the top of the iron outer shell 1, and the edge of the opening at one end of the iron outer shell 1 is bent outwards. The side baffles 11 are L-shaped with the iron outer shell 1. The side baffles 11 are used for positioning and stopping the panel during assembly. The side baffles 11 are hollowed out and bent from the side of the iron outer shell 1 and are integrally formed with the iron outer shell 1 during molding. The fixing plate 12 is L-shaped with the top of the iron outer shell 1 and is integrally formed with the iron outer shell 1 during molding. The fixing plate 12 has a screw hole 121 in the middle, which is used for positioning and fixing.

[0019] As attached Figure 6 and 9As shown, the inner iron shell 2 has its upper and lower inner walls recessed inward near the small opening in the assembly space, reducing the height of the upper and lower inner walls and forming a stop structure to prevent over-insertion during use. The bottom of the inner iron shell 2 has barbs 21 that bend towards the assembly space on both sides near the small opening. The glue core 3 has a groove 31 near its tail end; when the glue core 3 is inserted into the assembly space, the barbs 21 engage in the groove 31 to prevent the glue core 3 from coming off.

[0020] like Figure 4 As shown, after the inner iron shell 2 is assembled into the receiving space of the outer iron shell 1, the front end of the inner iron shell 2 is exposed outside the receiving space. The outward bending of the opening edge of one end of the outer iron shell 1 forms a V-shaped groove 13 with the outer wall of the inner iron shell 2; wherein the glue sealing ring 4 is sealed at the V-shaped groove 13, and part of the glue sealing ring 4 is exposed outside the V-shaped groove 13; the glue sealing ring 4 is used to seal and waterproof when the product is assembled with the panel; the V-shaped groove 13 is used to hold the glue when the glue sealing ring 4 is applied.

[0021] like Figure 3 and 4 As shown, the adhesive sealing ring 4 is made of adhesive, preferably UV adhesive, silicone, epoxy resin adhesive, or underfill adhesive. The adhesive sealing ring 4 has a semi-circular head shape, which is more advantageous for assembly between the product and the panel. The thickness of the adhesive sealing ring 4 is 0.50 mm to 1.0 mm, which serves to seal against interference with the panel during assembly.

[0022] As attached Figure 1 and 4As shown, a novel waterproof structure for a USB Type-C connector female socket is described. The specific implementation involves assembling the core 3 into the assembly space of the inner metal shell 2, with a barb 21 engaging the groove 31 to prevent adhesive slippage. The assembled core 3 and inner metal shell 2 are then assembled into the receiving space of the outer metal shell 1. The top portion of the inner metal shell 2 protrudes outside the receiving space, forming a V-shaped groove 13 with the outwardly bent edge of the outer metal shell 1. Adhesive is applied to the V-shaped groove 13 to form an adhesive sealing ring 4. The adhesive is applied and shaped to achieve a sealing and waterproof structure between the USB Type-C connector and the panel. Different specifications of fixtures and different dispensing methods are designed for different structural products to meet various customer needs for different shapes and functions. When applying adhesive using the V-shaped groove 13, the adhesive is supported, reducing the height of the upper and lower inner walls at the tail of the inner metal shell 2, forming a stop structure. This prevents over-insertion and provides a stop. The barb 21 structure added to the tail of the inner metal shell 2, after assembling the core 3, serves to lock the core 3 in place, preventing it from slipping out. Adding baffles 11 to both sides of the metal casing 1 serves as positioning and stopping mechanisms, controlling the relative assembly position of the USB Type-C connector and the panel. A bent fixing plate 12 with screw holes 121 is added to the metal casing 1 for product positioning. This achieves a more sealed and waterproof finish, while also providing stopping and preventing adhesive deterioration.

[0023] 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.
