Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging socket technology, and specifically to a charging socket. Background Technology
[0002] As the number of new energy vehicles increases, the number of charging stations and charging piles also continues to increase, but it is still difficult to meet the charging demand. In order to improve charging efficiency and shorten charging time, it is necessary to achieve a larger charging current (such as 600A). However, high-current charging can easily lead to overheating, which affects charging efficiency. Therefore, conventional charging sockets can only support a maximum current of 250A, which is difficult to meet the high-current charging demand. Utility Model Content
[0003] The purpose of this invention is to provide a charging socket that meets the needs of high-current charging and improves charging efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a charging socket, including a socket assembly and a connector assembly, a power socket assembly, and a grounding socket assembly mounted on the socket assembly. The socket assembly includes a base and a power socket mounting position disposed on the base. The power socket assembly includes a power socket, a plurality of copper tube terminals connected to one end of the power socket, and a power wire connected to the free end of each copper tube terminal. The power socket assembly is installed in the power socket mounting position.
[0005] The aforementioned charging socket uses several copper tube terminals and connected power wires to distribute the charging current among multiple power wires and copper tube terminals, reducing the charging current on a single power wire and copper tube terminal, thereby avoiding overheating and enabling the charging socket to meet the needs of high-flow charging.
[0006] Furthermore, a power connection copper busbar is provided between the power socket and the copper tube terminal. The power socket is electrically connected to one end of the power connection copper busbar, and the copper tube terminal is electrically connected to the other end of the power connection copper busbar.
[0007] Furthermore, a waterproof ring is fitted onto the power cord. After the power socket assembly is installed, the waterproof ring is pressed into the gap between the power cord and the power socket mounting position by the first fixing member, thereby sealing the gap between the power cord and the power socket mounting position to achieve waterproofing.
[0008] Furthermore, the base is provided with a tail cover, which is detachably connected to the base, and the power socket mounting position is provided on the tail cover.
[0009] Furthermore, a waterproof ring is installed around the power socket. When the power socket assembly is installed, the waterproof ring is squeezed and deformed to seal the gap between the outer surface of the power socket and the base, thus achieving waterproofing.
[0010] Furthermore, a retaining ring mounting groove is provided around the power socket, and a retaining ring is installed in the retaining ring mounting groove. The retaining ring is a C-shaped retaining ring. After the power socket assembly is installed, one side of the retaining ring abuts against one end of the power socket mounting position to prevent the power socket assembly from becoming loose.
[0011] Furthermore, a power socket through hole is provided on the power socket mounting position. The inner diameter of the power socket through hole gradually decreases along the insertion direction of the power socket. The cross-sectional dimension of the retaining ring gradually decreases along the installation direction of the power socket. Moreover, the minimum inner diameter of the power socket through hole is smaller than the maximum outer diameter of the retaining ring.
[0012] Furthermore, the grounding socket assembly includes a grounding socket, a grounding wire connected to the grounding socket, a waterproof ring for the grounding wire disposed between the grounding wire and the tail cover, and a second fixing member that presses and fixes the waterproof ring for the grounding wire onto the tail cover.
[0013] Furthermore, the tail cap is provided with a locking claw. After the grounding socket assembly is installed, the locking claw limits the grounding socket assembly to prevent it from loosening.
[0014] In combination with the above technical solutions, compared with the prior art, this utility model has the following beneficial effects:
[0015] The charging socket provided by this utility model distributes the charging current across multiple sets of copper tube terminals and power wires, reducing the charging current on a single copper tube terminal and power wire to avoid overheating. This prevents overheating from affecting charging efficiency and enables the charging socket to meet high-current charging needs. Attached Figure Description

Detailed Implementation
[0026] To illustrate the technical features, objectives, and effects of this utility model in detail, the following description, in conjunction with the accompanying drawings and embodiments, provides a further detailed explanation. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0027] Please see the appendix Figure 1-9 A charging socket includes a socket assembly 1 and a connector assembly 4, a power socket assembly 2, and a ground socket assembly 3 mounted on the socket assembly 1. The socket assembly 1 includes a base 11 and a power socket mounting position 123 disposed on the base 11. The power socket assembly 2 includes a power socket 21, a plurality of copper tube terminals 23 connected to one end of the power socket 21, and a power wire 24 connected to the free end of each copper tube terminal 23. The power socket assembly 2 is mounted in the power socket mounting position 123.
[0028] In the above embodiments, the use of multiple copper tube terminals 23 and power wires 24 connected thereto can disperse the current of a single power wire 24 and copper tube terminal 23 during the charging process, avoiding overheating that would affect charging efficiency. The power wires 24 and copper tube terminals 23 are dispersed into several groups and installed with gaps, which also facilitates timely heat dissipation and further avoids overheating, enabling the charging socket to meet the needs of continuous high-current charging.
[0029] Based on the above embodiments, a power connection copper busbar 22 is provided between the power socket 21 and the copper tube terminal 23. One end of the power socket 21 is electrically connected to the power connection copper busbar 22, and the other end of the copper tube terminal 23 is electrically connected to the power connection copper busbar 22. The power connection copper busbar 22 connects multiple sets of copper tube terminals 23 and power wires 24 into one unit, enabling the power socket assembly 2 to achieve modular production and testing, thereby improving production and maintenance efficiency.
[0030] Based on the above embodiments, a waterproof ring 25 is provided on the power cord 24. After the power socket assembly 2 is installed, the waterproof ring 25 is pressed into the gap between the power cord 24 and the power socket mounting position 123 by the first fixing member 26, thereby sealing the gap between the power cord 24 and the power socket mounting position 123 and achieving waterproofing.
[0031] Based on the above embodiments, a tail cover 12 is provided on the base 11, and the tail cover 12 is detachably connected to the base 11. The power socket mounting position 123 is disposed on the tail cover 12. For example, the tail cover 12 and the base 11 are connected by a snap-fit connection to improve installation efficiency.
[0032] Based on the above embodiments, a waterproof ring 212 is installed around the power socket 21. When the power socket assembly 2 is installed, the waterproof ring 212 is squeezed and deformed to seal the gap between the outer surface of the power socket 21 and the base 11, thereby achieving waterproofing.
[0033] Based on the above embodiments, a retaining ring mounting groove 211 is provided around the power socket 21, and a retaining ring 27 is installed in the retaining ring mounting groove 211. The retaining ring 27 is a C-shaped retaining ring. After the power socket assembly 2 is installed, one side of the retaining ring 27 abuts against one end of the power socket mounting position 123 to prevent the power socket assembly 2 from loosening. Using the retaining ring 27 to limit the power socket assembly 2 makes the structure simpler and the cost lower.
[0034] Based on the above embodiments, a power socket through hole 122 is provided on the power socket mounting position 123. The inner diameter of the power socket through hole 122 gradually decreases along the insertion direction of the power socket 21, and the cross-sectional dimension of the retaining spring 27 gradually decreases along the installation direction of the power socket 21. Furthermore, the minimum inner diameter of the power socket through hole 122 is smaller than the maximum outer diameter of the retaining spring 27. During installation, the outer surface of the retaining spring 27 is elastically deformed by the pressure of the inner surface of the power socket through hole 122, allowing the retaining spring 27 to pass through the power socket through hole 122. After passing through the power socket through hole 122, the retaining spring 27 returns to its original position to prevent the power socket 21 from dislodging from the power socket through hole 122.
[0035] Based on the above embodiments, the grounding socket assembly 3 includes a grounding socket 31, a grounding wire 32 connected to the grounding socket 31, a grounding wire waterproof ring 33 disposed between the grounding wire 32 and the tail cover 12, and a second fixing member 34 that presses and fixes the grounding wire waterproof ring 33 to the tail cover 12. The grounding wire waterproof ring 33 is used to waterproof the connection between the grounding wire 32 and the socket assembly 1. For example, the second fixing member 34 and the tail cover 12 are connected by a snap-fit connection to improve installation efficiency.
[0036] Based on the above embodiments, the tail cap 12 is provided with a claw 121. After the grounding socket assembly 3 is installed, the claw 121 clamps the grounding socket assembly 3. For example, the outer circumference of the grounding socket 31 is provided with a step, and the claw 121 is elastic. After the grounding socket assembly 3 is installed, the free end of the claw 121 is engaged on the step on the outer circumference of the grounding socket 31 to prevent the grounding socket assembly 3 from becoming loose.
