Description

Technical Field

[0001] This utility model relates to a charging stand, and more particularly to a CCS2 modular charging stand. Background Technology

[0002] In existing CCS2 electric vehicle charging sockets, the low-voltage and high-voltage wires are mostly crimped or soldered to the charging socket terminals and then spun out. This makes the wiring harness assembly complex, time-consuming, and has poor assembly processability. In particular, the charging socket needs to be equipped with temperature sensors to monitor the temperature of the electrical terminals. The wiring harness ends are connected to the temperature sensors, and a large number of temperature sensors are used, each with its own spun wire. This makes the wiring harness end assembly complex, further complicating the assembly process. Moreover, the products flow from disassembled parts to the next production site, making it impossible to test the performance of the product assembly. There are many materials to control for the wiring harness terminals, making management inconvenient, resulting in high product production costs and long product production cycles.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0036] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 A CCS2 modular charging base includes a main body 2, with a plug-in cavity 16 at the front end for matching with a charging gun, and a stepped hole 13 axially opened inside for accommodating electrical terminals. The plug-in end of the electrical terminals is located inside the plug-in cavity 16, and a control unit 9 for measuring the temperature of the electrical terminals is also provided inside.

[0037] The low-voltage plug-in 4 is detachably located at the rear end of the main body 2 and is connected to the control unit 9 to output signals to the outside, thereby reducing the use of temperature detection wires, simplifying the assembly process, and facilitating the testing of the product assembly performance when the product flows from the disassembled parts to the next production site. The wiring harness control materials are less, management is convenient, the product production cost is reduced, and the product production cycle is shortened.

[0038] In this embodiment, as Figure 4 As shown, a PE terminal 10 is disposed inside the main body 2, and the PE terminal 10 is accommodated in a grounding hole 14 axially opened inside the main body 2. The plug end of the PE terminal 10 is located in the plugging cavity 16. The PE terminal 10 can be kept inside the main body 2 by a rear cover that is detachably disposed at the rear end of the main body 2. The connection end of the PE terminal 10 is connected to a copper busbar outside the main body 2 for grounding.

[0039] In this embodiment, as Figure 6 As shown, the control unit 9 is connected to the PP terminal 12 and the CP terminal 11 respectively, and the PP terminal 12 and the CP terminal 11 are respectively housed in the signal holes 15 axially opened inside the main body 2. The plug-in ends of the PP terminal 12 and the CP terminal 11 are located in the plug-in cavity 16. When the charging gun is plugged into the main body 2, the CP terminal 11 will send a wake-up signal to the vehicle to activate the vehicle's control circuit and put the vehicle into the charging state. The CP signal will change due to the change in the resistance inside the gun. The vehicle controller determines whether the charging gun and the charging socket are reliably connected by detecting the change in the CP signal, and controls the state of the charging indicator light accordingly. The PP terminal 12 makes the current parameters between the charging device and the device being charged match each other, ensuring the safety and stability of the current charging process and avoiding problems such as overheating and open circuit caused by current mismatch.

[0040] In this embodiment, as Figure 6 , Figure 7 , Figure 10 The control unit 9 includes a PCB board, and the PCB board is equipped with a temperature sensor that can detect the temperature of electrical terminals.

[0041] In a further implementation, such as Figure 7As shown, thermally conductive silicone 17 is provided between the temperature sensor and the electrical terminal so that the thermally conductive silicone 17 can contact both the temperature sensor and the electrical terminal simultaneously, indirectly conducting heat to achieve temperature monitoring. The temperature sensor will have different resistance values ​​at different temperatures, and the vehicle body identifies the temperature of the temperature sensor by identifying different resistance values. The temperature of AC terminal 6 and DC terminal 7 is very important. Excessive temperature will affect the conductivity and contact performance of AC terminal 6 and DC terminal 7, increasing the contact resistance, which will lead to increased voltage, reduced transmission efficiency, and affect the normal operation of the equipment. Prolonged high temperature will also accelerate the aging and damage of the terminals, shorten their service life, and increase the maintenance cost and replacement frequency of the equipment. The thermally conductive silicone 17 has good thermal conductivity, tight adhesion, insulation and shock resistance, and has achieved good results in practical applications.

[0042] In this embodiment, as Figure 7 As shown, the electrical terminals include a DC terminal 7 and an AC terminal 6. The DC terminal 7 is used for the transmission of direct current, and the AC terminal 6 is used for the transmission of alternating current.

[0043] In a further implementation, Figure 11 , Figure 12 and Figure 13 The DC terminal 7 includes a flat body 701 and a cylindrical body 702. A protrusion 704, connecting to the end of the cylindrical body 702, is radially provided at one end of the flat body 701. The protrusion 704 ensures complete connection with the end of the cylindrical body 702. A circular hole 703 is formed at the free end of the cylindrical body 702, allowing an insulating cap to be installed within it. The cylindrical body 702 is formed using a cold forging process. The protrusion 704 and the cylindrical body 702 are connected by friction welding. Compared to fully machined terminals, this significantly reduces waste and terminal costs while maintaining terminal performance, making it highly competitive. The DC terminal 7 is cold-forged using a copper rod. The initial extrusion process forms an 8mm male pin structure on one end and a flat structure on the other. The width of the flat structure can be adjusted to accommodate different wire diameters by flattening it into different widths, resulting in strong product versatility. After the 8mm male pin end of the terminal is formed using a cold forging process, a 703 round hole needs to be machined to assemble the insulating cap of the European standard DC terminal 7. The flat structure is made into a T-shaped profile using a stamping process, and then directly stamped into flat structures of different widths to accommodate different wire diameters, further enhancing product versatility. The machined 8mm male pin end and the stamped flat structure are then connected together using a friction welding process, and the welding slag is removed by machining. The final product's appearance and performance are consistent with the machined terminal.

[0044] In a further embodiment, the free end of the columnar body 702 abruptly changes forward to form an arc-shaped portion 705. This structure facilitates the insertion of the DC terminal 7, and the arc-shaped portion 705 serves as a guide.

[0045] In a further embodiment, the columnar body 702 abruptly changes radially to form a thrust relief protrusion 706, which serves as a limiting element.

[0046] In this embodiment, as Figure 1 As shown, the rear end of the main body 2 is detachably provided with a sealing back cover 5 for fixing the wiring of the electrical terminals. The sealing back cover 5 can keep the wiring fixed inside the connector, avoid loosening and poor contact, and prevent damage to the wiring caused by external pulling. In a further improvement, the sealing back cover 5 is provided with a sealing ring 8 for wrapping the wiring, and the sealing ring 8 is located inside the main body 2. By configuring the sealing ring 8, it can play the roles of dustproof, waterproof, airtight protection and vibration buffer.

[0047] In this embodiment, as Figure 1 , Figure 8 and Figure 9 As shown, the front end of the main body 2 is equipped with a dust cover 1 to seal the insertion cavity 16. By embedding the dust cover 1 into the insertion cavity 16 for sealing, if the interface of the charging dock is exposed to the outside for a long time, dust is easy to accumulate. Dust entering the interior of the charging dock may affect the performance of the charging dock, which may lead to poor contact of the charging interface, intermittent charging, or even failure to charge normally. The dust cover 1 can effectively block dust, keep the interface clean, and ensure the normal use of the charging dock. The charging dock interface may be damaged by collision, friction, etc. The dust cover 1 can play a buffer role to a certain extent, reduce the direct impact of external factors on the interface, thereby extending the service life of the charging dock interface. In addition, in a humid environment, moisture is not easy to enter the charging interface.

[0048] In this embodiment, to prevent accidental disconnection when the main body 2 is connected to the charging gun, and to ensure personal safety and anti-theft protection, such as Figure 1 As shown, the main body 2 is provided with an electronic lock 3 for self-locking when the charging gun is docked.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
