Description

Technical Field

[0001] This application relates to the field of electrical connection technology, and in particular to a connector and a power supply system. Background Technology

[0002] As energy storage devices become increasingly larger, they can be used as portable power sources both indoors and outdoors. These devices support charging and power supply functions, and some can even supply power to the grid. Energy storage devices typically connect to the grid via connectors, which usually include a socket and a plug. The socket connects to the power source, and the plug connects to the energy storage device. The connection between the energy storage device and the grid is achieved through the insertion and connection of the plug and socket.

[0003] However, when the power source and the energy storage device are electrically connected, if the current transmitted between the power source and the energy storage device is too large, it can easily cause the energy storage device to be damaged due to overload. Utility Model Content

[0004] This application provides a connector and power supply system that can prevent energy storage devices from being damaged due to overload, and better meet users' safety requirements for charging and discharging.

[0005] In a first aspect, this application provides a connector, comprising:

[0006] A socket includes a base and a male plug portion, an overload protection switch, and an electrical control component disposed on the base, wherein the electrical control component is electrically connected to the male plug portion;

[0007] The plug includes a female connector and a connecting wire harness, wherein the female connector is electrically connected to the male connector, and the connecting wire harness is electrically connected to the female connector via the overload protection switch;

[0008] The power transmission line is electrically connected to the electrical control component and is used to electrically connect the male connector to the power supply so as to transmit the power supply current between the male connector and the power supply.

[0009] A communication line is electrically connected to the overload protection switch. The communication line is used to transmit a current signal corresponding to the power supply current to the overload protection switch, so that the overload protection switch controls the connection between the connecting wire harness and the female connector according to the current signal.

[0010] Secondly, this application also provides an overload protection switch that can be opened and closed according to the current signal, thereby realizing the connection and disconnection between the connecting harness and the female connector, and thus realizing the connection and disconnection between the energy storage device and the power supply. This allows the overload protection switch to disconnect in time when the power supply current transmitted by the transmission line is too large, thereby disconnecting the energy storage device from the power supply and preventing the energy storage device from being damaged due to overload, thus better meeting the user's safety requirements for charging and discharging.

[0011] The beneficial effects of this application are as follows: the overload protection switch can be opened and closed according to the current signal, thereby realizing the connection and disconnection between the connecting harness and the female connector, and thus realizing the connection and disconnection between the energy storage device and the power supply. This allows the overload protection switch to disconnect in time when the power supply current transmitted by the transmission line is too large, thereby disconnecting the energy storage device from the power supply, thus preventing the energy storage device from being damaged due to overload, and better meeting the user's safety requirements for charging and discharging.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] This application provides a connector and a power supply system to solve the problem in the related art that when a power source such as the power grid is electrically connected to an energy storage device through a connector, if the current transmitted between the power source and the energy storage device is too large, the energy storage device is easily damaged due to overload.

[0024] Firstly, this application provides a connector 100, such as Figure 1 and Figure 2 As shown, connector 100 includes socket 10, plug 20, power line 30, and communication line 40.

[0025] The socket 10 includes a base 11, a male plug portion 12, an overload protection switch 13, and an electrical control assembly 14 disposed on the base 11. The electrical control assembly 14 is electrically connected to the male plug portion 12, which is used to connect the socket 10 to the power grid (e.g., electricity). Figure 7 The components that are electrically connected to the power supply 61, etc., and the electrical control component 14 can play a role in voltage stabilization and voltage conversion between the power grid and the male plug part 12.

[0026] The plug 20 includes a female connector 21 and a connecting harness 22. The female connector 21 is electrically connected to the male connector 12, and the connecting harness 22 is electrically connected to the female connector 21 via an overload protection switch 13. It is understood that the connecting harness 22 is used to electrically connect to an energy storage device 63 (such as a battery), thereby achieving an electrical connection between the energy storage device 63 and the socket 10, and further achieving an electrical connection between the energy storage device 63 and the power supply 61. The male connector 12 and the female connector 21 may have plug-in interfaces. By plugging the female connector 21 into the male connector 12, a detachable connection and electrical connection between the plug 20 and the socket 10 can be achieved, thereby achieving an electrical connection between the energy storage device 63 and the power supply 61. The energy storage device 63 may have a charging function and can also charge household appliances and other electrical devices 64 (such as...). Figure 7 In addition to its power supply function, the energy storage device 63 can also have the function of supplying power to the grid or other power sources 61 in reverse.

[0027] The transmission line 30 is electrically connected to the electrical control component 14, and is used to electrically connect the male connector 12 to the power supply 61, so as to transmit the supply current between the male connector 12 and the power supply 61. It can be understood that the transmission line 30 can be electrically connected to the power grid, etc., to realize the electrical connection between the power supply 61 and the male connector 12, thereby realizing the electrical connection between the power supply 61 and the energy storage device 63. When the power supply 61 charges the energy storage device 63, the supply current is transmitted from the power supply 61 to the energy storage device 63 through the transmission line 30; when the energy storage device 63 supplies power to the power supply 61, the supply current is transmitted from the energy storage device 63 to the power supply 61 through the transmission line 30.

[0028] Communication line 40 is electrically connected to overload protection switch 13. Communication line 40 is used to transmit a current signal corresponding to the supply current to overload protection switch 13, enabling overload protection switch 13 to control the connection between wiring harness 22 and female connector 21 based on the current signal. Communication line 40 can also connect to distribution panel 62 (e.g., ...). Figure 7 Electrical connection: The distribution panel 62 may include a smart meter. The power supply 61 is electrically connected to the transmission line 30 through the distribution panel 62. The power supply current transmitted between the power supply 61 and the energy storage device 63 flows through the distribution panel 62, enabling the distribution panel 62 to receive charging and discharging data of the power supply current between the power supply 61 and the energy storage device 63, and to transmit the current signal corresponding to the power supply current to the overload protection switch 13 through the communication line 40. This can add and enrich the user's cyclic power consumption scenarios and improve the user's use and experience.

[0029] It is understandable that the overload protection switch 13 is an electrically controlled switch. The overload protection switch 13 can be opened and closed according to the current signal, thereby realizing the connection and disconnection between the connecting harness 22 and the female plug part 21, and thus realizing the connection and disconnection between the energy storage device 63 and the power supply 61. This allows the overload protection switch 13 to disconnect in time when the power supply current transmitted by the transmission line 30 is too large, thereby disconnecting the energy storage device 63 from the power supply 61, thus preventing the energy storage device 63 from being damaged due to overload, and better meeting the user's safety requirements for charging and discharging.

[0030] In some embodiments of this application, the socket 10 further includes a housing 15, which is located on opposite sides of the base 11 along with the overload protection switch 13. The housing 15 is connected to the base 11 to form a receiving cavity, in which the electronic control component 14 is located. It should be noted that the receiving cavity formed by the housing 15 and the base 11 provides good sealing protection for the electronic control component 14, effectively preventing water and dust damage. This reduces the risk of short circuits caused by water and dust, further enhancing the safety of the connector 100 during use and better meeting users' safety requirements for charging and discharging.

[0031] It should also be noted that the socket 10 can be installed in various ways on the wall or other locations. Taking the socket 10 installed on the wall as an example, the housing 15 is connected to the wall, and the overload protection switch 13 is located on the side of the base 11 away from the wall, which makes it convenient for the user to connect the plug 20 to the overload protection switch 13, and also makes the maintenance and replacement of the overload protection switch 13 more convenient. When installing the socket 10, the housing 15 can be attached to the wall, and the socket 10 is installed on the wall surface. When installing the socket 10, the housing 15 can also be installed inside the wall, and the overload protection switch 13 is exposed outside the wall. Of course, in other embodiments, the socket 10 may not have a housing 15, and the socket 10 can be installed on the wall or other locations through devices such as a junction box.

[0032] In some embodiments, a sealing element 50 is provided between the base 11 and the housing 15. The base 11 is sealed to the housing 15 through the sealing element 50. The sealing element 50 is clamped and fixed between the base 11 and the housing 15, and its opposite sides contact the base 11 and the housing 15 respectively, thereby achieving a seal between the housing 15 and the base 11, and thus providing better sealing protection for the electronic control assembly 14. The sealing element 50 can be formed of plastic, rubber, metal or other materials.

[0033] In some embodiments, the housing 15 is provided with a first wire hole 151 for the transmission line 30 and the communication line 40 to run. The first wire hole 151 is provided with a sealing cover 16 to seal the first wire hole 151. The sealing cover 16 is detachably connected to the housing 15. Understandably, the first wiring hole 151 provides a routing channel for the power transmission line 30 and the communication line 40, facilitating their entry and exit from the housing cavity and connection with other components. When the socket 10 is not installed on a wall or other location, the power transmission line 30 and the communication line 40 do not need to be routed, and the sealing cover 16 is connected to the housing 15 to keep the first wiring hole 151 sealed, preventing water and dust from entering the housing cavity through the first wiring hole 151. When the socket 10 needs to be installed, the sealing cover 16 can be removed to open the first wiring hole 151, allowing the power transmission line 30 to pass through the first wiring hole 151 and connect to the electrical control component 14, and the communication line 40 to pass through the first wiring hole 151 and connect to the overload protection switch 13. In this case, the power transmission line 30 and the communication line 40 can seal the first wiring hole 151, thus ensuring that the housing cavity is always in a good sealed state.

[0034] In some embodiments, each side panel of the housing 15 has at least one first wire-passing hole 151, allowing the power transmission line 30 and the communication line 40 to be routed from any side of the housing 15, thereby making the routing of the power transmission line 30 and the communication line 40 more convenient according to actual needs. It is understood that the housing 15 includes multiple side panels located on different sides. When the housing 15 has n side panels, each of the n side panels has a first wire-passing hole 151, and at least n first wire-passing holes 151 are provided, where n is an integer; for example, as... Figure 2 As shown, the housing 15 is formed by connecting five side plates: bottom side plate 152, first side plate 153, second side plate 154, third side plate 155 and fourth side plate 156. Each of the five side plates of the housing 15 has a first wire hole 151, and at least five first wire holes 151 are provided.

[0035] like Figure 3 As shown, in some embodiments, the sealing cover 16 includes a sealing portion 161 and a connecting portion 162 disposed around the periphery of the sealing portion 161. The sealing portion 161 is connected to the inner wall of the first wire passage hole 151 through the connecting portion 162, and the thickness of the connecting portion 162 is less than the thickness of the sealing portion 161. It can be understood that the shape of the sealing cover 16 matches the shape of the first wire passage hole 151. Since the thickness of the connecting portion 162 is relatively thin, the connecting portion 162 is easier to separate from the housing 15. When wiring is required, the sealing portion 161 can be tapped to separate the connecting portion 162 from the housing 15, thereby removing the sealing cover 16 to open the first wire passage hole 151, making the removal of the sealing cover 16 more convenient and quick.

[0036] Furthermore, the connecting portion 162 is inclined from the sealing portion 161 in a direction away from or close to the sealing portion 161, so that the connecting portion 162 is inclined relative to the sealing portion 161, making the sealing portion 161 and the connecting portion 162 clearly distinguishable, making it easier for the user to select the tapping point when tapping, and when the sealing portion 161 is tapped, the inclined connecting portion 162 is more likely to be pulled and broken, thus making it easier to knock off the sealing cover 16.

[0037] In some embodiments, the diameter of the first wire hole 151 can be 22.5 mm, which is better suited for the 21.25 mm waterproof conduit used by North American users, making it easier for North American users to experience and use.

[0038] Continue to participate Figure 1 and Figure 2 As shown, in some embodiments, one end of the communication line 40 is connected to a connector 41, which is plugged into the overload protection switch 13 to electrically connect the communication line 40 to the overload protection switch 13. It can be understood that in this embodiment, the end of the communication line 40 connected to the overload protection switch 13 is directly connected to the overload protection switch 13 via the connector 41. The connector 41 can be an RJ45 connector or other types. Directly plugging the connector 41 into the overload protection switch 13 achieves both physical and electrical connection between the communication line 40 and the overload protection switch 13, making the connection between the communication line 40 and the overload protection switch 13 more convenient. The communication line 40 can be an 82 network cable or other types of network cable.

[0039] It should also be noted that when one end of the communication line 40 is connected to the overload protection switch 13, such as Figure 1 and Figure 2 As shown, the communication line 40 and the transmission line 30 can also be two sets of conductive wires in the same wire bundle. In this case, the communication line 40 can be routed through the first wire hole 151. Of course, the communication line 40 and the transmission line 30 can be two independent sets of conductive wires. The routing of the communication line 40 and the transmission line 30 does not interfere with each other. In this case, the communication line 40 can or cannot be routed through the first wire hole 151.

[0040] like Figure 4As shown, in some other embodiments, the electronic control component 14 is electrically connected to the overload protection switch 13, and one end of the communication line 40 can be connected to the electronic control component 14 so that the communication line 40 is electrically connected to the overload protection switch 13 through the electronic control component 14. It is understood that in this embodiment, the communication line 40 is directly connected to the electronic control component 14 and electrically connected to the overload protection switch 13 through the electronic control component 14. A 485 connection terminal or other type of connection terminal 42 can be installed on the electronic control component 14. By making a hole in the connection terminal 42, one end of the communication line 40 is inserted into the hole of the connection terminal 42, thus achieving a physical and electrical connection between the communication line 40 and the connection terminal 42. This achieves an electrical connection between the communication line 40 and the electronic control component 14, and further achieves an electrical connection between the communication line 40 and the overload protection switch 13. This eliminates the need for an additional connector 41 on the overload protection switch 13 and eliminates the need for a socket hole on the socket 10 for the connector 41 on the communication line 40 to pass through, thereby reducing the production cost of the socket 10. Among them, the communication line 40 can be an RS485 communication line or other types of communication lines.

[0041] It should also be noted that the communication line 40 and the transmission line 30 can be two sets of conductive wires in the same wire bundle. In this case, the communication line 40 can be routed through the same through hole and connected to the electrical control component 14. When installing the communication line 40 and the transmission line 30, only one through hole operation is required, making the installation and use of the communication line 40 and the transmission line 30 more convenient. In addition, the wire diameter of the communication line is usually smaller than that of the network cable, making it easier to perform through hole operation on the communication line 40.

[0042] Continue to participate Figure 4 As shown, in some embodiments, the communication line 40 can pass through the first wire hole 151 and be electrically connected to the electronic control component 14 so that the communication line 40 is electrically connected to the overload protection switch 13, and the first wire hole 151 provides a routing channel for the communication line 40.

[0043] like Figure 5 and Figure 6 As shown, in some embodiments, the electrical control component 14 and the overload protection switch 13 are located on opposite sides of the base 11. It is understood that when installing the socket, the housing 15 is typically mounted on the wall. In this case, the overload protection switch 13 is located on the side of the base 11 away from the wall, allowing for convenient manual operation by the user.

[0044] Furthermore, the base 11 is provided with a second cable pass hole 111 for the communication cable 40 to run. It is understood that the second cable pass hole 111 also provides a routing channel for the communication cable 40, allowing for more routing options and better meeting the usage needs, scenarios, and habits of different users. Users can choose the appropriate routing method according to their own needs and usage habits. In addition, when the housing 15 is installed inside a wall, the communication cable 40 can pass through the second cable pass hole 111 from the side of the base 11 away from the wall and connect to the electrical control component 14, making the routing of the communication cable 40 more convenient when the housing 15 is installed inside a wall. The number of second cable pass holes 111 can be one, two, or more.

[0045] Continue to participate Figure 1 and Figure 2 As shown, in some embodiments, the socket 10 further includes a waterproof cover 17, which forms a waterproof cavity with the base 11. The waterproof cover 17 is movable relative to the base 11 to open and close the waterproof cavity. The base 11 is provided with a limiting opening 112 communicating with the waterproof cavity, and the male plug portion 12 passes through the limiting opening 112. It should be noted that the waterproof cover 17 can be rotatably connected to the base 11, slidably connected, or connected in other movable ways. The waterproof cover 17 can also be detachably mounted on the base 11. The waterproof cover 17 can provide a sealed protection for the male plug portion 12, preventing water and dust from contacting the male plug portion 12, thereby further improving the safety of the connector 100 during use. In addition, the waterproof cover 17 can be moved to open the waterproof cavity, making it convenient for the user to operate the male plug portion 12 and the female plug portion 21 at any time.

[0046] In some embodiments, the socket 10 further includes a circuit breaker box 18, which is located on the same side of the base 11 as the waterproof cover 17 and spaced apart from the waterproof cover 17. The circuit breaker box 18 and the base 11 form a protective cavity. The circuit breaker box 18 can move relative to the base 11 to open and close the protective cavity. The overload protection switch 13 is located in the protective cavity. It should be noted that the circuit breaker box 18 can be rotatably connected to the base 11, slidably connected, or connected in other movable ways. The circuit breaker box 18 can also be detachably mounted on the base 11. The circuit breaker box 18 can provide a sealed protection for the overload protection switch 13, preventing water and dust from contacting the overload protection switch 13, thereby further improving the safety of the connector 100 during use. In addition, the circuit breaker box 18 can be moved to open the protective cavity, allowing the user to operate the overload protection switch 13 at any time.

[0047] Specifically, both the waterproof cover 17 and the circuit breaker box 18 have wiring openings for the plug 20 to run, thus providing a wiring channel for the plug 20.

[0048] In some embodiments, the waterproof cover 17 and the circuit breaker box 18 are arranged along the length of the base 11, and the electrical control component 14 is positioned opposite the waterproof cover 17, so that the base 11 does not need to have a large width, and the arrangement of the waterproof cover 17, the circuit breaker box 18 and the electrical control component 14 is more compact, which can make full use of the installation space on the base 11, thereby reducing the overall volume of the socket 10.

[0049] In some embodiments, the connecting harness 22 includes multiple conductive connecting wires 221. One end of each conductive connecting wire 221 is electrically connected to the overload protection switch 13, and the other end is electrically connected to the female connector 21. At least a portion of the conductive connecting wires 221 extend along the periphery of the overload protection switch 13 and are fixed to the overload protection switch 13, so that the overload protection switch 13 provides limiting constraints for the conductive connecting wires 221, preventing the multiple conductive connecting wires 221 from tangling. The conductive connecting wires 221 can also fix the overload protection switch 13, making the overload protection switch 13 more securely installed.

[0050] It should also be noted that only a portion of the conductive connecting wires 221 can be electrically connected to the female connector 21 through the overload protection switch 13, while the other portion of the conductive connecting wires 221 can be directly electrically connected to the female connector 21. The overload protection switch 13 only controls the on / off state of a portion of the conductive connecting wires 221, thereby controlling the on / off state of the connecting wire harness 22 and the female connector 21.

[0051] like Figure 2 and Figure 5 As shown, in some embodiments, the base 11 is provided with a plurality of limiting ribs 19 on the side near the overload protection switch 13. The plurality of limiting ribs 19 are arranged around the periphery of the overload protection switch 13 to form a limiting groove 191. The overload protection switch 13 is snapped into the limiting groove 191 to realize the installation of the overload protection switch 13 on the base 11 and prevent the overload protection switch 13 from separating from the base 11.

[0052] Secondly, based on the aforementioned connector 100, this application also provides a power supply system, such as... Figure 7 As shown, the power supply system includes a power supply 61, a distribution panel 62, an energy storage device 63, and a connector 100 as described in any of the above embodiments. The distribution panel 62 is electrically connected to the power supply 61, the power transmission line 30, and the communication line 40. The distribution panel 62 is used to transmit the power supply current through the power transmission line 30 and the male plug 12. The distribution panel 62 is also used to transmit a current signal corresponding to the power supply current to the overload protection switch 13 through the communication line 40. The energy storage device 63 is electrically connected to the connecting harness 22.

[0053] In some embodiments, the distribution panel 62 can also be electrically connected to electrical equipment 64 such as household appliances, so that the electrical equipment 64 can be powered by the power grid and energy storage device 63; the distribution panel 62 can also be electrically connected to solar generator 65, so that the solar generator 65 can power the power source 61 and energy storage device 63, thereby further adding and enriching the user's cycle power consumption scenarios and improving the user's use and experience.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
