[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0026] Please see Figure 1-10This utility model provides an embodiment of a multifunctional DC charging dock, comprising a housing 1, a charging terminal assembly 3 on one side of the housing 1, and a separator 2 on the other side of the housing 1, wherein two identical power cords 4 are fitted inside the separator 2; the charging terminal assembly 3 includes a housing 30, and a support plate 35 is provided inside the housing 30; one side of the support plate 35 has a wiring portion 37, and the other side of the support plate 35 has a socket 38; the separator 2 includes a support frame 20, and a fastener 22 is provided inside the support frame 20, which is connected to the housing 1 to cause the fastener 22 to fasten to the outside of the power cords 4, thereby fixing power cords 4 of different diameters. Specifically, the fastener 22 is also provided with a claw 21; when the support frame 20 moves toward the housing 30, the claw 21 causes the claw 21 to wrap around the outside of the power cords 4.

[0027] In summary, the power cord 4 is secured by the support frame 20 and the fastener 22, thus ensuring its reliable fixation. Furthermore, since the diameter of the claw 21 can vary with the support frame 20 (i.e., the diameter of the claw 21 can increase or decrease), and the fastener 22 is replaceable, manufacturers can easily select a suitable separator 2 for the outer diameter of the power cord 4 to ensure reliable fixation, thereby expanding the functionality of the charging dock.

[0028] Based on the above solution, the two power cords are separated by the separator 2, with one power cord 4 located on the upper surface of the connector 37 and the other on the lower surface of the connector 37. This improves the conductivity of the charging dock. In particular, the support plate 35 has two connectors 37, allowing the device to connect four power cords 4 simultaneously. This ensures rapid current flow while reducing overheating of the charging dock. Specifically, the connector 37 is plate-shaped, and the end of the power cord 4 is connected to the connector 37 via a copper plate. Bolts are then used to pass through the copper plate and the connector 37 to fix the power cord 4 to the connector 37. Therefore, it facilitates both connecting and inserting the power cords 4. Connecting multiple power cords 4 together further increases the current-carrying capacity, reducing overheating during device use.

[0029] Specifically, the fastener 22 is also provided with a claw 21; when the support frame 20 moves toward the housing 30, the claw 21 enters into the conical hole 25 provided on the support frame 20. After the support frame 20 is connected to the housing 1, the conical hole 25 causes the claw 21 to retract and surround the outside of the power cord 4. The separator 2 also includes a pad 23, and the pad 23 is provided with a round hole 24 for easy insertion of the power cord. The round hole 24 has a spiral protrusion inside. The pad 23 is made of rubber. Therefore, when the two ends of the separator 2 are connected to the connecting buckle 7 on the housing 1, the pad 23 causes the separator 2 to achieve a seal between the separator 2 and the housing 1. At the same time, the protrusion inside the round hole 24 can also be used to seal the outer wall of the power cord 4 to improve the sealing performance of the device.

[0030] To facilitate real-time acquisition of device information, the charging terminal assembly 3 also includes a signal terminal 34, which is provided with pins 311. Additionally, a grounding terminal 310 is provided on the signal terminal 34 for grounding purposes. Specifically, the pins 311 pass through the housing 1 and connect to the provided connector 5 to facilitate communication between the charging dock and external components. The low-voltage signal pin is used to transmit weak electrical signals, ensuring precise circuit control. It plays a crucial role in signal interaction and command transmission in electronic devices. It enables stable low-power signal transmission between different modules and accurately transmits the minute signals collected by sensors to the processing chip.

[0031] Meanwhile, one end of the grounding terminal 310 is exposed outside the housing 1 to facilitate the connection of the grounding wire. In specific applications, a copper lug is used to connect to the grounding terminal 310. Based on this, the device can obtain the charging dock information in real time while increasing the current flow rate. In particular, the grounding terminal 310 makes it simple and convenient for users to ground the charging dock.

[0032] In order to ensure that the electrodes inside the plug are smoothly inserted into the socket 38, one end of the socket 38 passes through the sleeve 312 provided in the housing 30 and is connected to the locking ring 36. The locking ring 36 abuts against the end face of the sleeve 312 to support and fix one end of the socket 38.

[0033] Furthermore, since the locking ring 36 has a barb 315 on the side facing the socket 38, and the barb 315 is adapted to be connected to the hook groove 316 on the socket 38, when the locking ring 36 hooks into the hook groove 316, it can support the end of the socket 38 while preventing the socket 38 from moving backward under force.

[0034] Furthermore, since the sleeve 312 is also provided with a notch 313, and the locking ring 36 is adapted to be connected to the notch 313 through the provided protrusion 314, when the locking ring 36 is connected to the socket 38, the notch 313 can also be used to connect with the protrusion 314 to prevent the locking ring 36 and the socket 38 from rotating axially.

[0035] Based on the above solution, since the outer shell 1 is provided with a slot 8 on the side facing the housing 30, and the housing 30 is inserted into the slot 8 through the provided plug-in part 318, one end of the housing 30 can extend into the interior of the outer shell 1, and the slot 8 is used to wrap the plug-in part 318 to improve the stability of the connection between the housing 30 and the outer shell 1.

[0036] Furthermore, since the outer end face of the slot 8 is also provided with a buckle 6, and the buckle 6 is adapted to be connected with the buckle pin 320 provided on the outer wall of the housing 30, the stability of the outer shell 1 and the housing 30 after connection can be further enhanced. Conversely, pushing the buckle 6 outwards facilitates the disassembly of the outer shell 1 and the housing 30.

[0037] To improve the sealing performance of the outer casing 1 and the housing 30 after connection, a mounting groove 317 is provided on the outer circumferential surface of the insertion part 318, and a groove 319 is provided on the side of the housing 30 away from the insertion part 318. Furthermore, a sealing ring 31 is installed in the mounting groove 317, and a sealing gasket 32 ​​is installed in the groove 319. Based on this, the sealing ring 31 and the sealing gasket 32 ​​are used to seal the front and rear sides of the housing 30.

[0038] In addition, the charging terminal assembly 3 also includes a mounting plate 33, which is connected to the housing 30, and a cover 39 is provided on the mounting plate 33. Therefore, when the plug is unplugged, the cover 39 can be used to cover the charging dock to reduce the entry of dust. At the same time, the mounting plate 33 is connected to the housing 30 by bolts, and the sealing gasket 32 ​​can be used to complete the seal between the mounting plate 33 and the housing 30.

[0039] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
