[0001] This utility model relates to the field of charging dock technology, and specifically to a charging dock that is waterproof and has a stable connection. Background technology:

[0002] Charging docks are used to charge electronic devices and are among the most common electronic peripherals. They are used very frequently in work and daily life, and with the rise of various types of electronic products, the styles of charging docks have also increased. However, due to the enhanced functionality of electronic products and the significantly shortened battery life, most manufacturers, when iterating on charging docks, usually prioritize fast charging performance and size reduction, thus neglecting other performance aspects.

[0003] However, in practical use, the connection stability, waterproofing, and dustproofing of charging docks are particularly important when used in different environments. Therefore, some charging docks on the market currently have significant limitations in their use due to weaknesses or deficiencies in certain performance aspects. For example, Chinese utility model patent application CN209730378U discloses a charging and discharging connector, which includes: a charging dock, a discharging plug, and a charging plug; the charging dock includes: a base body, multiple spring pins disposed in a first inner cavity of the base body, a second inner cavity located on both sides of the first inner cavity, and a charging female terminal disposed in the second inner cavity; the discharging plug includes: a body, signal pins disposed on the top surface of the body corresponding to the distribution of the spring pins, a discharging terminal disposed on the top surface of the body and distributed on both sides of the spring pins, and a power pin disposed on the side of the body, with the portion of the power pin embedded in the body making electrical contact with the portion of the discharging terminal embedded in the body; the charging plug includes: a housing and a charging male terminal disposed at one end of the housing. It has both charging and discharging functions, and the discharging plug has a small size through structural optimization design. In addition, the charging socket for the above-mentioned charging and discharging connection has spring pins, which help to provide cushioning during insertion and avoid damage.

[0004] However, this existing charging and discharging connector still has the following shortcomings:

[0005] In this technical solution, a charging plug and a discharging plug are set up so that the connector has both charging and discharging functions. However, the connector does not have a design to enhance its waterproof performance, which results in insufficient waterproof and dustproof performance. In addition, its small size and lack of hole structure for stable connection lead to poor connection stability.

[0006] In view of the above, the inventors propose the following technical solution. Utility model content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waterproof and stable charging dock.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a waterproof and stable charging base, comprising: a housing having an external connection hole and a mating groove formed thereon, the mating groove having a protruding irregular hole for mating with an external electrical socket; a protective layer vertically distributed within the accommodating space to prevent foreign matter from flowing into the interior; a PCB board disposed within the protective layer, the PCB board having an interface exposed through the external connection hole for connecting with an external terminal; a magnetic ring disposed in the mating groove and surrounding the irregular hole, the outer wall of the magnetic ring abutting against the inner wall of the mating groove; at least two spring pins passing through the irregular hole, one end of the spring pin extending outward from the outer surface of the irregular hole and protruding outward, the other end of the spring pin passing through the protective layer and fixed to the PCB board.

[0009] Furthermore, in the above technical solution, the spring pin includes: a shaft section, a plug section integrally formed with the shaft section and used for plugging into the PCB board, and a conductive section integrally formed with the shaft section and used for communicating with the outside. The size of the conductive section is smaller than the size of the shaft section, and the size of the plug section is also smaller than the size of the shaft section.

[0010] Furthermore, in the above technical solution, the shaft segment also has a ring of blocking parts protruding from its periphery for axially limiting the spring pin.

[0011] Furthermore, in the above technical solution, at least two through holes corresponding to the spring pin are provided on the irregular hole position, and the through holes pass through the shell and lead to the protective layer.

[0012] Furthermore, in the above technical solution, a sub-groove for assisting in docking stability is also provided in the docking groove, and both the sub-groove and the irregular hole are semi-circular.

[0013] Furthermore, in the above technical solution, the PCB board has several mounting holes for mounting the interface, and the mounting holes are arranged at the lower end of the PCB board.

[0014] Furthermore, in the above technical solution, the interface includes: a USB mounting bracket connected to the PCB board and a USB interface board disposed on the USB mounting bracket for communication with the outside.

[0015] Furthermore, in the above technical solution, the USB mounting bracket is formed with several pins for matching and mounting with the mounting hole, and the USB mounting bracket is also formed with several limiting protrusions recessed inward for locking and limiting the USB interface board, and the limiting protrusions are distributed on both sides of the USB mounting bracket.

[0016] Furthermore, in the above technical solution, the USB mounting bracket wraps around the USB interface board in a circumferential manner, and an inwardly tapering connecting strip is also formed on the USB mounting bracket. Correspondingly, an avoidance groove is recessed on the USB interface board, and the connecting strip is inserted into the avoidance groove to limit the position of the USB interface board.

[0017] Furthermore, in the above technical solution, the protective layer has at least two through holes corresponding to the perforations, and the through holes lead to the PCB board.

[0018] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In summary, in this utility model, the spring pin passes through the irregular hole and is fixed to the PCB board by welding. During charging, the contact pressure is strong, effectively reducing impedance and enhancing charging efficiency. Simultaneously, by setting a low-pressure molded protective layer on the outside of the PCB board, it can effectively prevent water and dust, improving the product's rigidity. While ensuring charging efficiency, it also has good waterproof and dustproof performance, effectively enhancing product strength. Furthermore, unlike existing structures, this utility model also sets a magnetic ring in the docking groove to attract the external socket during charging, effectively preventing accidental detachment of the charging base, further strengthening the connection stability during charging, and is suitable for various types of charging plugs, with a wide range of applications and strong market competitiveness.

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] See Figures 1 to 3As shown, a waterproof and stable charging dock includes: a housing 1 with an external connection hole 11 and a mating groove 12 formed thereon, the mating groove 12 having a protruding irregular hole 121 for mating with an external electrical socket; a protective layer 2 vertically distributed within the receiving space to prevent foreign objects from entering the charging dock; a PCB board 3 disposed within the protective layer 2, the PCB board 3 having an interface 31 exposed through the external connection hole 11 for connecting with an external terminal; a magnetic ring 4 disposed in the mating groove 12 and surrounding the irregular hole 121, the outer wall of the magnetic ring 4 abutting against the inner wall of the mating groove 12; and at least two spring pins 5 passing through the irregular hole 121, one end of the spring pin 5 extending outward from the outer surface of the irregular hole 121, the other end of the spring pin 5 passing through the protective layer 2 and fixed to the PCB board 3.

[0024] In this invention, the spring pin 5 passes through the irregular hole 121 and is fixed to the PCB board 3 by welding. During charging, the strong contact pressure effectively reduces resistance and enhances charging efficiency. Simultaneously, by setting a low-pressure molded protective layer 2 on the outside of the PCB board 3, it effectively provides waterproofing and dustproofing, improving the product's rigidity. While ensuring charging efficiency, it also possesses excellent waterproof and dustproof performance, effectively enhancing product strength. Furthermore, unlike existing structures, this invention also includes a magnetic ring 4 in the docking groove 12 for attraction with the external socket during charging, effectively preventing accidental detachment of the charging base and further strengthening connection stability during charging. It is applicable to various types of charging plugs, has a wide range of applications, and is highly competitive in the market.

[0025] The spring pin 5 includes: a shaft section 51, a plug-in section 52 integrally formed with the shaft section 51 for insertion into the PCB board 3, and a conductive section 53 integrally formed with the shaft section 51 for external communication. The conductive section 53 is smaller than the shaft section 51, and the plug-in section 52 is also smaller than the shaft section 51. Here, the conductive section 53 is smaller than the shaft section 51 but larger than the plug-in section 52, and its end has a curved surface to facilitate insertion and communication with an external socket.

[0026] The shaft section 51 also has a protruding ring of blocking portion 510 for axially limiting the spring pin 5. Here, when the spring pin 5 is installed on the PCB board 3, the blocking portion 510 will abut against the PCB board 3 to avoid over-insertion or poor contact of the spring pin 5.

[0027] At least two through holes 1210 corresponding to the spring pin 5 are provided on the irregular hole 121. The through holes 1210 pass through the housing 1 and lead to the protective layer 2. Here, the size of the through hole 1210 is larger than the size of the blocking part 510; and the end of the conducting section 53 extends beyond the opening of the through hole 1210 and protrudes outward to better connect with the external socket.

[0028] The docking groove 12 also includes a docking sub-groove 122 for assisting in docking stability. Both the docking sub-groove 122 and the irregularly shaped hole 121 are semi-circular. Experiments have shown that, compared to conventionally shaped holes, the irregularly shaped docking sub-groove 122 and irregularly shaped hole 121 offer superior docking stability, effectively preventing accidental disengagement, and are adaptable to more extreme operating environments, demonstrating excellent applicability.

[0029] The interface 31 includes: a USB mounting bracket 311 connected to the PCB board 3 and a USB interface board 312 disposed on the USB mounting bracket 311 for communication with the outside.

[0030] The PCB board 3 has several mounting holes 32 for mounting the interface 31, and these mounting holes 32 are arranged at the lower end of the PCB board 3. The USB mounting bracket 311 has several pins 3110 formed on it for mating with the mounting holes 32. The USB mounting bracket 311 also has several recessed protrusions 3111 formed on its sides for locking and limiting the USB interface board 312. Here, the USB mounting bracket 311 is fixedly connected to the PCB board 3 via the pins 3110, and the limiting protrusions 3111 further limit its movement, effectively increasing its service life and enhancing its waterproof performance.

[0031] The USB mounting bracket 311 wraps around the USB interface board 312 in a circumferential manner. The USB mounting bracket 311 also has an inwardly tapering connecting strip 3112. Correspondingly, the USB interface board 312 has a recessed clearance groove 313, in which the connecting strip 3112 is inserted to limit the position of the USB interface board 312. The protective layer 2 has at least two through holes 23 corresponding to the perforations 1210, and these through holes 23 lead to the PCB board 3.

[0032] In summary, in this invention, the spring pin 5 passes through the irregular hole 121 and is fixed to the PCB board 3 by welding. During charging, the strong contact pressure effectively reduces resistance and enhances charging efficiency. Simultaneously, by setting a low-pressure molded protective layer 2 on the outside of the PCB board 3, it effectively provides waterproofing and dustproofing, improving the product's rigidity. While ensuring charging efficiency, it also possesses excellent waterproof and dustproof performance, effectively enhancing product strength. Furthermore, unlike existing structures, this invention also includes a magnetic ring 4 in the docking groove 12 for attraction with the external socket during charging, effectively preventing accidental detachment of the charging base and further strengthening connection stability during charging. It is applicable to various types of charging plugs, has a wide range of applications, and is highly competitive in the market.
