[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] According to the first aspect of the present utility model, Figure 1-Figure 2 As shown, an electrical connection assembly is provided, including a control box housing 1 and a plug assembly, the plug assembly is used to electrically connect to a power supply, the plug assembly includes a plug socket and a plug terminal 3 and a quick-plug terminal 5 that are partially arranged in the plug socket and electrically connected to each other, the plug assembly also includes a sensor 7 arranged in the plug socket and a signal terminal 6 that is partially arranged in the plug socket, the signal terminal 6 is electrically connected to the sensor 7, the plug socket is detachably connected to the outer wall of the control box housing 1, the control box housing 1 contains an electronic device 8, the quick-plug terminal 5 and the signal terminal 6 are both electrically connected to the electronic device 8, and the plug terminal 3 is partially exposed outside the control box housing 1.

[0035] With the rapid development and popularization of new energy vehicles, the research and development of charging guns for electric vehicles is particularly important. The charging gun includes a control box and a charging gun head and a charging plug connected to the two ends of the control box by cables. The existing charging gun is electrically connected to the charging plug through a cable that is at least partially exposed outside the control box. The cable and the charging plug occupy a large space, and the conductive part of the cable is fixedly connected to the conductive terminal in the control box by welding or crimping, and cannot be disassembled, so that the cable and the charging plug connected to the cable end cannot be removed from the control box housing 1, resulting in the charging gun can only adapt to its fixedly connected charging plug, and the power supply type that the charging plug can connect to will also be fixed, and it cannot obtain power supply from more types of power sources.

[0036] The utility model makes the plug end of the control box in the form of a plug assembly, and the plug assembly is integrally connected to the control box housing 1 in a detachable manner. The plug assembly occupies a small space and can be quickly removed from the control box housing 1, so that the control box housing 1 can be replaced and connected to different plug assemblies. When the plug socket of the plug assembly is installed and manufactured, different plug terminals 3 are installed, so that the control box housing 1 can be electrically connected to different plug terminals 3. Different plug terminals 3 can be adapted to different power supply types, thereby allowing the control box housing 1 to be electrically connected to different power supplies through the plug assembly to provide them with electrical energy.

[0037] In some embodiments, Figure 2 As shown, it also includes a cable arranged in the plug socket, and the plug terminal 3 and the quick-plug terminal 5 as well as the signal terminal 6 and the sensor 7 are electrically connected through the cable.

[0038] The plug terminal 3 is electrically connected to the quick-connect terminal 5 through a cable. The quick-connect terminal 5 can transmit the electric energy received by the plug terminal 3 from the power supply to the control box housing 1. The sensor 7 is electrically connected to the signal terminal 6. The sensor 7 can detect the temperature signals of various components in the control box through the signal terminal 6.

[0039] Alternatively, if Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the side wall of the control box housing 1 is provided with an installation position 11 which is connected to the bottom wall and is recessed from the outside to the inside. The plug assembly can be detachably installed in the installation position 11.

[0040] The plug socket includes a protective shell 2 and a terminal bracket 4, the plug terminal 3 and the sensor 7 are connected to the protective shell 2, the quick-plug terminal 5 and the signal terminal 6 are arranged in the terminal bracket 4, the protective shell 2 is sleeved on the outside of the terminal bracket 4, and the protective shell 2 is fixed to the mounting position 11 by a snap-fit ​​structure.

[0041] The protective shell 2 is sleeved on the outside of the terminal bracket 4 and is clamped on the installation position 11 through a clamping structure. The quick-plug terminals 5 and the signal terminals 6 in the terminal bracket 4 can be protected at the installation position 11 of the control box housing 1, and the terminal bracket 4 and the control box housing 1 can be relatively fixed, which is also convenient for the installation and arrangement of the plug terminals 3 and the sensor 7. Such a structural design simplifies the structure of the plug end, reduces the occupied space, and is also convenient for assembly.

[0042] In some embodiments, Figure 5-Figure 6 As shown, the snap-fit ​​structure is one of the slots or buckles provided on the protective shell 2, and the other of the slots or buckles provided on the mounting position 11. When the protective shell 2 and the mounting position 11 are snapped and connected, the slots and the buckles are snap-fitted and connected.

[0043] The card slot and the snap-on connection allow the protective shell 2 to be fixed on the mounting position 11 of the control box housing 1, preventing the plug terminal 3 from being disconnected from the quick-plug terminal 5 and the signal terminal 6 from being disconnected from the sensor 7. The fixed protective shell 2 fixes the quick-plug terminal 5 and the signal terminal 6 in the terminal bracket 4 relative to the control box housing 1, thereby ensuring the stability of the electrical connection between the quick-plug terminal 5 and the electronic device 8 and between the signal terminal 6 and the electronic device 8, thereby ensuring the safety of electricity use.

[0044] In some embodiments, Figure 3 As shown, the installation position 11 and the protective shell 2 are provided with mutually matching guiding structures (not shown in the figure), and the plug assembly enters the installation position 11 under the guidance of the guiding structures.

[0045] The provision of the guide structure can guide the plug assembly into the installation position 11 more quickly, thereby increasing the installation speed of the plug assembly and the control box housing 1 .

[0046] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the terminal bracket 4 includes a mounting surface 41, a connecting plug extending vertically from the mounting surface 41, and a reinforcing portion 42 extending from the mounting surface 41 toward the connecting plug and wrapping the connecting plug, and a sealing ring 9 is provided between the outer wall of the reinforcing portion 42 and the protective shell 2.

[0047] The provision of the sealing ring 9 can prevent water vapor and impurities from entering between the terminal bracket 4 and the protective shell 2, affecting the electrical connection between the plug terminal 3 and the quick-connect terminal 5 and between the signal terminal 6 and the sensor 7, causing electrical risks.

[0048] In some embodiments, Figure 7 As shown, the connecting plug includes a plurality of parallel-axis plug-in barrels 43 extending vertically on the mounting surface 41 , and the quick-connect terminals 5 and the signal terminals 6 are arranged in the plug-in barrels 43 .

[0049] The quick-plug terminals 5 and the signal terminals 6 are arranged in the plug-in barrel 43 . The arrangement of the plug-in barrel 43 can fix and protect the quick-plug terminals 5 and the signal terminals 6 .

[0050] In some embodiments, Figure 8 As shown, the terminal bracket 4 is made of hard rubber, the sealing ring 9 is made of soft rubber, and the sealing ring 9 is injection-molded on the outer wall of the reinforcement portion 42 by a two-color injection molding process.

[0051] Double-color injection molding refers to injecting the hard rubber material of the terminal bracket 4 and the soft rubber material of the sealing ring 9 into the same set of molds, and injecting the terminal bracket 4 and the sealing ring 9 into an integrated form, thereby improving the aesthetics and assembly performance of the product and making assembly more convenient.

[0052] In some embodiments, Figure 2 As shown, the plug terminal 3 and the sensor 7 are formed on the protective shell 2 by injection molding.

[0053] The plug terminal 3 and the sensor 7 are formed on the protective shell 2 by an injection molding process, and the three are integrated. The integrated structure is easier to assemble. Fixing the plug terminal 3 and the sensor 7 on the protective shell 2 also facilitates the electrical connection between the plug terminal 3 and the quick-plug terminal 5, and the electrical connection between the signal terminal 6 and the sensor 7.

[0054] In some embodiments, Figure 3 As shown, the protective shell 2 includes a side wall and a bottom wall, and the plug terminal 3 is at least partially exposed outside the side wall of the protective shell 2 or outside the bottom wall of the protective shell 2 .

[0055] The purpose of exposing part of the plug terminal 3 outside the protective shell 2 is to connect the exposed plug terminal 3 to a power source.

[0056] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
