Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a power connector for charging electric vehicles. Background Technology

[0002] With the increasing popularity of electric vehicles, the safety and reliability of charging equipment are receiving growing attention. As a key component in the electric vehicle charging process, the performance of the power connector directly affects charging efficiency and user safety. During the charging process, due to factors such as high current transmission, increased contact resistance, poor connection, or high temperatures, abnormal temperature rises may occur at the contact points between the plug on the power connector and the electric vehicle charging dock. If the temperature is too high, it will not only accelerate material aging but may also cause serious accidents such as fires.

[0003] Therefore, it is necessary to design a power connector for electric vehicle charging that can promptly disconnect when an abnormal temperature is detected at the connection point between the plug and the charging dock to avoid accidents caused by overheating. Utility Model Content

[0004] To overcome the drawback of abnormal temperature rise at the contact point between the plug and the charging dock of an electric vehicle during charging due to factors such as high current transmission, increased contact resistance, poor connection, or high temperatures, which can accelerate material aging and potentially cause serious accidents such as fires, this invention provides a power connector for electric vehicle charging that can promptly disconnect when an abnormal temperature is detected at the connection point between the plug and the charging dock, thus preventing accidents caused by overheating.

[0005] The technical implementation scheme of this utility model is as follows: a power connector for charging electric vehicles includes a power cord, a connector, a slot, a plug, a charging dock, an insulating component, and a disconnecting component. The power cord has two parts, left and right. The right side of the left power cord is connected to the connector. The front and rear sides of the connector are connected to slots. The right side of the connector is connected to the plug. The left side of the right power cord is connected to the charging dock. The charging dock is provided with an insulating component that can provide insulation protection when the plug is connected to the charging dock. The insulating component is provided with a disconnecting component that can disconnect in time when an abnormal temperature is detected at the docking position.

[0006] Optionally, the connector has anti-slip texture on the upper side.

[0007] Optionally, the insulating assembly includes a connecting frame, a mounting plate, a protective sleeve, a guide rod, and a return spring. The connecting frame is connected to both the upper and lower sides of the charging dock, and the mounting plate is connected between the left sides of the connecting frame. The protective sleeve is sleeved on the outside of the charging dock. The connecting frame is connected to the mounting plate with a guide rod, and the guide rod is slidably connected to the protective sleeve. The connecting frame is connected to the protective sleeve with a return spring.

[0008] Optionally, the protective cover is made of polyvinyl chloride.

[0009] Optionally, it also includes a detachment assembly, which includes a temperature sensor, an electric push rod, a locking head, a rotating frame, and a torsion spring. The temperature sensor is connected inside the charging dock. The rotating frame is rotatably connected to both the front and rear parts of the mounting plate. The electric push rod is connected to the left side of the rotating frame. The electric push rod is electrically connected to the temperature sensor. The locking head is connected to the telescopic end of the electric push rod. The torsion spring is connected between the rotating frame and the mounting plate.

[0010] Optionally, it also includes indicator lights, with indicator lights connected to the left sides of both the upper and lower parts of the mounting plate.

[0011] The present invention has the following advantages: 1. When the temperature sensor detects an abnormal temperature, the present invention will provide an audible and visual warning through an indicator light. At the same time, the electric push rod will drive the locking head to move to the left, and the locking head will push the connector to move to the left, so that the plug will disengage from the charging dock. This achieves the effect of timely disengagement when an abnormal temperature is detected at the docking position between the plug and the charging dock, thus avoiding accidents caused by overheating.

[0012] 2. This utility model uses the connector to move and squeeze the protective sleeve, causing the protective sleeve to move to the right on the guide rod. The return spring is compressed and contracts. The protective sleeve blocks the connection between the plug and the charging dock, and the power is supplied through the power cord. This achieves the effect of blocking the connection between the plug and the charging dock, preventing electric arcs caused by personnel contact. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0020] A power connector for charging electric vehicles, such as Figures 1-3 As shown, it includes a power cord 1, a connector 2, a slot 3, a plug 4, a charging dock 5, an insulating component, and a disengagement component. The power cord 1 has two parts, left and right. The right side of the left power cord 1 is connected to the connector 2. The upper side of the connector 2 has anti-slip texture for easy gripping. The front and rear sides of the connector 2 are connected to the slot 3. The right side of the connector 2 is connected to the plug 4. The left side of the right power cord 1 is connected to the charging dock 5. The charging dock 5 is equipped with an insulating component, and the insulating component is equipped with a disengagement component.

[0021] like Figures 2-5 As shown, the insulating assembly includes a connecting frame 7, a mounting plate 8, a protective sleeve 9, a guide rod 10, and a return spring 11. The charging docking seat 5 is connected to the connecting frame 7 on both the upper and lower sides. The mounting plate 8 is connected between the left sides of the connecting frame 7. The protective sleeve 9 is sleeved on the outside of the charging docking seat 5. The protective sleeve 9 is made of polyvinyl chloride and has good insulation performance. The connecting frame 7 is connected to the mounting plate 8 by a guide rod 10. The guide rod 10 is slidably connected to the protective sleeve 9. The connecting frame 7 is connected to the protective sleeve 9 by a return spring 11.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, it also includes a detachment assembly, which includes a temperature sensor 6, an electric push rod 12, a locking head 121, a rotating frame 13, a torsion spring 14, and an indicator light 15. The temperature sensor 6 is connected inside the charging dock 5. The rotating frame 13 is rotatably connected to both the front and rear parts of the mounting plate 8. The electric push rod 12 is connected to the left side of the rotating frame 13. The electric push rod 12 is electrically connected to the temperature sensor 6. The locking head 121 is connected to the telescopic end of the electric push rod 12. The torsion spring 14 is connected between the rotating frame 13 and the mounting plate 8. The indicator light 15 is connected to the left side of both the upper and lower parts of the mounting plate 8.

[0023] When using this device, first install the mounting plate 8 onto the electric vehicle charging docking point, then insert the plug 4 on the connector 2 into the charging docking seat 5, allowing the plug 4 to pass through the protective sleeve 9. During the docking process, the movement of the connector 2 will squeeze the protective sleeve 9, causing it to move to the right on the guide rod 10. The return spring 11 is compressed and contracts, thus shielding the connection between the plug 4 and the charging docking seat 5 through the protective sleeve 9. Power is supplied through the power cord 1, thereby providing shielding when the plug 4 connects to the charging docking seat 5 and preventing electric arcs caused by personnel contact. As the protective sleeve 9 moves to the right, it will contact and squeeze the rotating frame 13, causing the rotating frame 13 to rotate. The torsion spring 14 deforms, causing the locking head 121 to contact the locking slot 3. During the charging process... Temperature sensor 6 detects the temperature between plug 4 and charging dock 5. When temperature sensor 6 detects an abnormal temperature, it will provide an audible and visual warning via indicator light 15. At the same time, electric push rod 12 drives the locking head 121 to move to the left. The locking head 121 pushes connector 2 to move to the left, causing plug 4 to disengage from charging dock 5. This allows for timely disengagement when an abnormal temperature is detected at the docking position between plug 4 and charging dock 5, preventing accidents caused by overheating. As connector 2 moves to the left, reset spring 11 gradually returns to its original position, causing protective sleeve 9 to move to the left and reset. When protective sleeve 9 no longer contacts rotating frame 13, torsion spring 14 returns to its original position, causing rotating frame 13 to rotate and reset, so that locking head 121 no longer contacts slot 3.
