[0003] In everyday use, Type-C charging sockets inevitably come into contact with moisture, such as in humid bathroom environments, during rainy weather, or after accidentally spilling water. However, many existing Type-C charging sockets have significant flaws in their waterproof design. Some sockets rely solely on a simple outer shell structure to block moisture, lacking effective waterproof sealing measures. When moisture enters the socket, it can easily corrode critical components such as internal electrical connectors and terminals, leading to problems such as short circuits and oxidation. This severely affects the normal use of the socket and may even damage connected electronic devices, causing economic losses and inconvenience to users. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waterproof TYPE-C side-plug charging socket, solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A waterproof TYPE-C side-plug charging socket includes:

[0007] The outer casing has a plug at one end, a first adhesive groove at the other end, and a second adhesive groove at the bottom;

[0008] A metal bracket is mounted to the outside of the housing by means of a slot on the housing.

[0009] An electrical connector is located inside the housing, with its front end extending into the plug and having an upper row of terminals, and its bottom having a lower row of terminals;

[0010] The rear cover is located behind the electrical connector and is connected to the housing.

[0011] The sealing ring is installed in the limiting groove on the outside of the plug;

[0012] The first glue tank is located between the outer shell and the back cover. Waterproof glue is poured into the first glue tank and the second glue tank. The bottom of the metal bracket is provided with a limiting card for insertion into an external circuit board.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the second glue tank has pads at both ends, and the pads have limiting posts. The outer shell is inserted into the circuit board through the limiting posts. The height of the waterproof glue poured into the second glue tank is adapted to the thickness of the pads.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The pads and limiting posts at both ends of the second adhesive groove provide initial positioning and installation foundation for the connection between the outer casing and the circuit board, allowing the outer casing to be accurately and stably placed on the circuit board. The height of the waterproof adhesive poured into the second adhesive groove is matched with the thickness of the pads, ensuring that the waterproof adhesive fully fills the second adhesive groove, effectively preventing moisture from entering the interior from the bottom of the outer casing and providing a good waterproof seal. At the same time, it avoids excessive waterproof adhesive overflow, which could affect the normal installation of other components or cause unnecessary material waste. This approach ensures waterproof performance while also taking into account the convenience and economy of installation.

[0017] Furthermore, the metal bracket has a through hole, and the outer shell has a retaining clip in its slot; the metal bracket is engaged and limited by the retaining clip through the through hole.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] The metal bracket engages with the retaining clips within the outer casing via through holes, ensuring a more secure and reliable fixation. Compared to simpler installation methods, this interlocking mechanism effectively prevents the metal bracket from loosening or shifting during use, enhancing the overall stability of the socket structure. It provides more reliable external support and protection for internal electrical connectors and other components, ultimately extending the socket's lifespan.

[0020] Furthermore, the limiting post of the pad is interference-fitted with the circuit board to form a mechanical fixation in the vertical direction.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The retaining post of the socket block has an interference fit with the circuit board, creating a strong mechanical fixing force in the vertical direction. This fixing method ensures a tight connection between the outer shell and the circuit board, preventing easy separation due to external vibrations or shaking of the socket, greatly improving the installation stability of the socket on the circuit board. Even in harsh operating environments, it ensures reliable electrical connection between the socket and the circuit board, reducing problems such as poor contact and signal interference caused by loose connections, thus improving the overall performance and reliability of the product.

[0023] Furthermore, the sealing ring has an O-ring structure in cross-section, which tightly covers the outer circumferential surface of the plug. When the plug is connected to the charging device, it is sealed by the sealing ring.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] The O-ring seal has excellent elasticity and sealing performance, tightly covering the outer circumferential surface of the plug. When the plug is connected to a charging device, the seal deforms elastically under the connection pressure, filling the tiny gaps at the connection point and forming a reliable sealing barrier. This effectively prevents moisture, dust, and other foreign matter from entering the socket from the connection point, protecting internal electrical connectors and terminals from damage. It ensures the socket functions properly in various environments, improving the product's waterproof and dustproof rating and overall safety.

[0026] Furthermore, the upper and lower terminals are electrically connected through a circuit board inside the electrical connector.

[0027] The beneficial effects of adopting the above-mentioned further solutions are:

[0028] The upper and lower rows of terminals are electrically connected via a circuit board inside the connector. This design makes the connection lines between the terminals more organized and orderly. The circuit board provides a stable conductive path for signal transmission between the terminals, reducing signal interference and resistance, and ensuring stable current and signal transmission. At the same time, this internal connection method facilitates manufacturing and quality control, improves product production efficiency and consistency, helps reduce production costs, and enhances the product's market competitiveness.

[0029] This utility model provides a waterproof TYPE-C side-plug charging socket. It has the following advantages:

[0030] The outer casing features a first and a second adhesive groove, both filled with waterproof adhesive. The first groove, located between the outer casing and the back cover, effectively prevents moisture from seeping into the interior through the seam between the two. The second groove, at the bottom, prevents moisture from entering from the bottom of the casing. This double protection significantly enhances the overall waterproof capability of the socket. The height of the waterproof adhesive poured into the second groove is matched to the thickness of the spacer. This design ensures that the waterproof adhesive fully fills the second groove for a good waterproof effect, without overflowing and affecting the installation of other components or causing material waste due to excessive adhesive. This demonstrates a reasonable compatibility between structural design and manufacturing process.

[0031] A sealing ring with an O-ring structure is installed in the limiting groove on the outside of the plug. This sealing ring tightly covers the outer circumferential surface of the plug. When the plug is connected to the charging device, the sealing ring can fit tightly against the connection point, forming a reliable sealing barrier that effectively prevents moisture from entering from the connection between the plug and the device, further enhancing the waterproof effect.

[0032] The metal bracket is mounted on the outside of the outer casing via a slot on the casing, and a through hole is provided on the metal bracket to engage with the fixing clip inside the slot on the casing for further positioning. This double-positioning method ensures that the metal bracket is firmly and stably installed on the casing, preventing loosening and providing a good external support structure for the entire socket. The second groove has pads at both ends, with limiting posts on the pads. The casing is inserted into the circuit board via these limiting posts, and the limiting posts and circuit board are interference-fitted. This interference fit creates a vertical mechanical fixation, allowing the casing to be securely mounted on the circuit board, preventing loosening due to socket shaking or external impact, and ensuring the stability of the electrical connection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A waterproof TYPE-C side-plug charging socket includes:

[0045] The outer casing 1 has a plug 108 at one end, a first adhesive groove 102 at the other end, and a second adhesive groove 105 at the bottom;

[0046] The metal bracket 2 is mounted on the outside of the housing 1 by means of the slot 101 on the housing 1;

[0047] An electrical connector 110 is located inside the housing 1, with its front end extending into the plug 108 and having an upper row of terminals 109, and its bottom having a lower row of terminals 104.

[0048] The rear cover 111 is located behind the electrical connector 110 and is connected to the housing 1;

[0049] The sealing ring 107 is installed in the limiting groove on the outside of the plug 108;

[0050] The first glue tank 102 is located between the outer shell 1 and the back cover 111. Waterproof glue is poured into the first glue tank 102 and the second glue tank 105. The bottom of the metal bracket 2 is provided with a limit card 201 for insertion into the external circuit board.

[0051] Example 2

[0052] To further optimize the waterproof performance, installation stability, and electrical connection reliability of this TYPE-C charging socket, for example, such as Figures 1 to 4As shown, this utility model also includes:

[0053] The second glue groove 105 has pads 103 at both ends, and the pads 103 have limiting posts. The outer shell 1 is inserted into the circuit board through the limiting posts. The height of the waterproof glue poured into the second glue groove 105 is adapted to the thickness of the pads 103. The pads 103 and their limiting posts at both ends of the second glue groove 105 provide the initial positioning and installation foundation for the connection between the outer shell 1 and the circuit board, so that the outer shell 1 can be accurately and stably placed on the circuit board. The matching height of the waterproof glue poured into the second glue groove 105 with the thickness of the pads 103 ensures that the waterproof glue fully fills the second glue groove 105, effectively preventing water from entering the interior from the bottom of the outer shell 1, thus providing a good waterproof seal. It also avoids excessive waterproof glue overflow, which could affect the normal installation of other components or cause unnecessary material waste. This ensures waterproof performance while taking into account the convenience and economy of installation.

[0054] The limiting post of the spacer 103 is interference-fitted with the circuit board, forming a vertical mechanical fixation. This interference fit creates a strong mechanical fixing force in the vertical direction. This fixing method ensures a tight connection between the outer shell 1 and the circuit board, preventing easy separation due to external vibrations or shaking of the socket, greatly improving the installation stability of the socket on the circuit board. Even in harsh operating environments, it ensures reliable electrical connection between the socket and the circuit board, reducing problems such as poor contact and signal interference caused by loose connections, thus improving the overall performance and reliability of the product.

[0055] The sealing ring 107 has an O-ring structure in cross-section, tightly covering the outer circumferential surface of the plug 108. When the plug 108 is connected to the charging device, the sealing ring 107 provides a seal. The O-ring structure of the sealing ring 107 has good elasticity and sealing performance, enabling it to tightly cover the outer circumferential surface of the plug 108. When the plug 108 is connected to the charging device, the sealing ring 107 undergoes elastic deformation under the connection pressure, filling the tiny gaps at the connection point between the plug 108 and the charging device, forming a reliable sealing barrier. This effectively prevents moisture, dust, and other foreign objects from entering the socket from the connection point between the plug 108 and the device, protecting the internal electrical connector 110 and terminals from damage, ensuring the socket functions normally in various environments, and improving the product's waterproof and dustproof rating and safety.

[0056] The upper row of terminals 109 and the lower row of terminals 104 are electrically connected via a circuit board inside the electrical connector 110. This design makes the connection lines between the terminals more organized and orderly. The circuit board provides a stable conductive path for signal transmission between the terminals, reducing signal interference and resistance, and ensuring stable transmission of current and signals. At the same time, this internal connection method facilitates manufacturing and quality control, improves product production efficiency and consistency, helps reduce production costs, and enhances the product's market competitiveness.

[0057] Example 3

[0058] To enhance the overall structural stability of the TYPE-C charging socket, ensure the safety of internal components, and improve product durability, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0059] The metal bracket 2 has a through hole 202, and the outer casing 1 has a retaining clip 106 in the slot 101. The metal bracket 2 is engaged and limited by the retaining clip 106 through the through hole 202, and the metal bracket 2 is engaged and limited by the retaining clip 106 in the slot 101 of the outer casing 1. This installation method makes the metal bracket 2 more securely and reliably fixed to the outer casing 1. Compared with a single installation method, the engagement and limiting mechanism can effectively prevent the metal bracket 2 from loosening or shifting during use, enhance the stability of the entire socket structure, provide more reliable external support and protection for internal components such as the electrical connector 110, and help extend the service life of the socket.

[0060] Working principle:

[0061] The metal bracket 2 is engaged with the fixing clip 106 in the slot 101 of the outer shell 1 through the through hole 202, thus completing the installation of the metal bracket 2 on the outside of the outer shell 1. At the same time, the outer shell 1 is inserted into the external circuit board through the limiting post on the pad 103, and the limiting post of the pad 103 is interference-fitted with the circuit board to form a vertical mechanical fixation, ensuring the initial stable installation of the outer shell 1 on the circuit board.

[0062] Waterproof adhesive is injected into the first adhesive groove 102 between the outer shell 1 and the back cover 111 and the second adhesive groove 105 at the bottom of the outer shell 1. The height of the waterproof adhesive injected into the second adhesive groove 105 is adapted to the thickness of the pad 103. Waterproof seal is achieved between the outer shell 1 and the back cover 111 and between the bottom of the outer shell 1 and the circuit board through the waterproof adhesive.

[0063] A sealing ring 107 with an O-ring cross-section is installed in the limiting groove on the outside of the plug 108, so that the sealing ring 107 tightly covers the outer circumferential surface of the plug 108. When the plug 108 is connected to the charging device, the sealing ring 107 seals the connection and prevents moisture from entering from the connection between the plug 108 and the charging device. When the waterproof TYPE-C side-plug charging socket is connected to the charging device, the upper row of terminals 109 and the lower row of terminals 104 are electrically connected to the charging device to charge the device. At the same time, the waterproof structure ensures that the internal circuitry will not be damaged by moisture during the charging process.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
