[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is in conjunction with the appendix Figures 1-7 The plug-in device of the present invention will be described in detail below.

[0030] The plug-in device of this utility model embodiment includes a plug, which has a first end and a second end. The first end includes a plug body 1 and a light-emitting element 2, and the second end includes either the plug body 1 or the plug body 1 and the light-emitting element 2. The first end is used to plug into and engage with a terminal to be charged. The second end is used to be electrically connected to an external power source to charge the terminal to be charged. The light-emitting element 2 is also electrically connected to the external power source to supply power to it. Alternatively, the second end can be electrically connected to a power-consuming body to supply power to it through the first end, and the light-emitting element 2 can be electrically connected to it to supply power when the power-consuming body is powered on.

[0031] In this embodiment of the plug-in device, when the light-emitting element 2 is electrically connected to an external power source, the external power source can charge the end to be charged through the plug and supply power to the light-emitting element 2, making the external power source stable and reliable. When the light-emitting element 2 is electrically connected to the power-consuming body, the end to be charged supplies power to the power-consuming body through the plug, and supplies power to the light-emitting element 2 after the power-consuming body is powered on. The end to be charged supplies power to the light-emitting element 2 through the power-consuming body, making the power supply method stable and reliable. It can be used to provide lighting or facilitate plug insertion, thereby improving the stability and reliability of the lighting provided by the light-emitting element 2.

[0032] Optionally, when the second end of the plug is electrically connected to an external power source, the external power source can simultaneously supply power to the light-emitting element 2. That is, the positive terminal of the light-emitting element 2 is connected to the positive terminal of the external power source, and the negative terminal of the light-emitting element 2 is connected to the negative terminal of the external power source. The light emitted by the light-emitting element 2 is used for illumination, facilitating the connection between the first end of the plug and the end to be charged, thus improving charging convenience. After charging is completed, the first end of the plug is separated from the end to be charged, i.e., the plug-in device is separated from the end to be charged, facilitating the storage of the plug-in device.

[0033] Optionally, depending on the application scenario of the plug-in device, the first end of the plug in the plug-in device may include a plug body 1 and a light-emitting element 2; the second end of the plug in the plug-in device may include a plug body 1 and a light-emitting element 2, or the second end of the plug may only include the plug body 1.

[0034] Optionally, the end to be charged can be a storage battery. When the ambient light is weak, the second end of the plug is electrically connected to an external power source. At this time, the light-emitting element 2 at the first end of the plug is energized and illuminates to facilitate the connection between the first end of the plug and the storage battery. The first end of the plug includes the plug body 1 and the light-emitting element 2, and the second end of the plug includes the plug body 1.

[0035] Optionally, when the second end of the plug is electrically connected to the power-consuming body, it is applicable to usage scenarios where the power-consuming body has one or more sockets, there are one or more terminals to be charged, and the power-consuming body and one or more terminals to be charged can be plugged in and detached respectively. The terminal to be charged is charged when the power-consuming body is separated from the terminal to be charged, i.e., the terminal to be charged is removed from the power-consuming body before charging (e.g., the terminal to be charged is placed in a charging cabinet for charging). After the terminal to be charged is finished charging, one terminal to be charged is first connected to one socket on the power-consuming body to supply power to the power-consuming body. After the power-consuming body is powered on, it supplies power to the light-emitting elements 2 of one or more plugs, and the one or more light-emitting elements 2 emit light, facilitating the subsequent plugging and mating of the terminal to be charged with the plugging device.

[0036] like Figure 3 As shown, the plug-in device includes a power-on module and a control module. The positive and negative terminals of the terminal to be charged are connected to the positive and negative terminals of the power-on module to supply power to the power-on module. When the power-on module is powered on, the power-on module sends a signal to the control module (for example, the signal is the output of the ignition switch). When the control module receives the signal, it controls the light-emitting element 2 to emit light.

[0037] Of course, in other embodiments, the main body of the power supply has one or more sockets, and there is one charging end. The charging end is connected to one socket on the main body of the power supply to supply power to the main body of the power supply. After the main body of the power supply is powered on, it supplies power to the light-emitting element 2 of one or more plug-in devices. The one or more light-emitting elements 2 emit light to realize the illumination of the surrounding environment.

[0038] In some embodiments, the plug-in device further includes a wire, with the second end of the plug connected to the wire. The wire is used for electrical connection to an external power source or a power-consuming entity. In this embodiment, the wire creates a certain distance between the plug and the external power source or power-consuming entity. The wire also facilitates moving the position of the light-emitting element 2 by pulling it, thereby enabling the flashlight function, increasing the illumination range of the light-emitting element 2, and achieving flexible lighting.

[0039] In some embodiments, the plug body 1 includes a base 11 and a plug terminal 12, with the plug terminal 12 disposed on the base 11 and the light-emitting element 2 disposed on the base 11. By disposing the plug terminal 12 and the light-emitting element 2 on the base 11, it is convenient to install and use the plug terminal 12 and the light-emitting element 2.

[0040] In some embodiments, such as Figure 1As shown, the base 11 has a receiving cavity 111, and the plug terminal 12 and the light-emitting element 2 are disposed within the receiving cavity 111. The receiving cavity 111 has an opening on the side adjacent to the plug, and the light-emitting element 2 is adjacent to the opening of the receiving cavity 111. By disposing of the plug terminal 12 and the light-emitting element 2 within the receiving cavity 111, the positions of the plug terminal 12 and the light-emitting element 2 can be fixed while protecting them. The proximity of the light-emitting element 2 to the opening of the receiving cavity 111 facilitates the diffusion of the light source emitted by the light-emitting element 2 outward from the base 11, thereby improving the illumination range of the light-emitting element 2.

[0041] In some embodiments, such as Figure 1 As shown, the plug in the connector also includes a switch module 3, which is connected in series with the light-emitting element 2. At least a portion of the switch module 3 is located within the receiving cavity 111. The base 11 has a through hole 112 that communicates with the receiving cavity 111, and a portion of the switch module 3 is located within the through hole 112. The switch module 3 is connected in series with an external power source; or, the switch module 3 is connected in series with the power-consuming component. By having at least a portion of the switch module 3 located within the receiving cavity 111 and a portion within the through hole 112, it is convenient to press the switch module 3 to turn the light-emitting element 2 on and off, thus meeting different usage scenarios.

[0042] In some embodiments, such as Figure 2 As shown, the plug in the connector also includes a switch protective cover 4, which is located at the through hole 112. The switch protective cover 4 can be pressed relative to the base 11 to activate and deactivate the switch module 3. The switch protective cover 4, located at the through hole 112, can effectively isolate external substances from the receiving cavity 111, improving the stability of the connector. Furthermore, by pressing the switch protective cover 4 to activate and deactivate the switch module 3, the light-emitting element 2 can be turned on and off.

[0043] In some embodiments, the plug-in device further includes a control module electrically connected to the switch module 3. The switch module 3 sends a signal to the control module when connected to an external power source or electrical appliance. The control module controls the light-emitting element 2 to emit light upon receiving the signal. The switch module 3 and the control module enable the light-emitting element 2 to be turned on and off.

[0044] Specifically, such as Figure 4 As shown, the positive and negative terminals of the external power supply are connected to the positive and negative terminals of the control module, respectively. The control module is connected to the positive terminal of the light-emitting element 2. One end of the switch module 3 is connected to the negative terminal of the light-emitting element 2, and the other end of the switch module 3 is connected to the negative terminal of the power supply. When the switch module 3 is closed, the light-emitting element 2 emits light; conversely, when the switch module 3 is open, the light-emitting element 2 does not light up.

[0045] In some embodiments, such as Figure 1As shown, the base 11 includes a housing 113 and a fixing plate 114. A receiving cavity 111 is formed on the housing 113, and the fixing plate 114 is disposed within the receiving cavity 111. The plug terminal 12 and the light-emitting element 2 are mounted on the fixing plate 114. During assembly, the plug terminal 12 and the light-emitting element 2 are first mounted on the fixing plate 114, and then the fixing plate 114 is installed in the receiving cavity 111. The fixing plate 114 helps to improve the stability and reliability of the plug-in device.

[0046] In some embodiments, such as Figure 1 As shown, the housing 113 includes an inner shell 1131 and an outer shell 1132. A receiving cavity 111 is formed on the inner shell 1131, and a fixing plate 114 is encapsulated in the receiving cavity 111. At least a portion of the inner shell 1131 is installed inside the outer shell 1132. The arrangement of the inner shell 1131 and the outer shell 1132 prevents the plug-in device from becoming loose during insertion and removal, thereby improving the stability of the plug-in device.

[0047] In some embodiments, the plug-in device further includes a control module, which is electrically connected to an external power supply and a light-emitting element 2, respectively. The control module includes a photosensitive device, which is electrically connected to the light-emitting element 2 to control the light-emitting element 2 to turn on and off.

[0048] Specifically, such as Figure 5 As shown, the positive and negative terminals of the external power supply are connected to the positive and negative terminals of the control module, respectively. The control module is connected to the positive terminal of the light-emitting element 2, and the photosensitive device is connected to the negative terminal of the light-emitting element 2. By utilizing the photosensitive characteristics of the photosensitive device, a voltage difference can be formed between the positive and negative terminals of the light-emitting element 2, thereby controlling the light-emitting element 2 to emit light.

[0049] In some embodiments, the plug-in device further includes a control module and a communication module. The communication module is connected to both an external power supply and the control module. The communication module sends a first signal to the control module when connected to the external power supply. The communication module has a serial port for sending a second signal to the control module. The control module controls the light-emitting element 2 to emit light upon receiving the first and second signals. The presence of the communication module and control module facilitates remote control of the light-emitting element 2's opening and closing.

[0050] Specifically, such as Figure 6 As shown, the positive and negative terminals of the external power supply are connected to the positive and negative terminals of the communication module to supply power to the communication module. When the communication module is powered on, it supplies power to the control module and sends a first signal to the control module. The serial port is located on the communication module and is used to send a second signal to the control module. When the control module receives the first signal and the second signal, it controls the light-emitting element 2 to emit light.

[0051] like Figure 7As shown, the plug-in device also includes a conversion module, which is connected to the external power supply and the light-emitting element 2 respectively. The conversion module is used to convert the voltage of the external power supply so that the light-emitting element 2 can adapt to the voltage of different external power supplies and improve compatibility.

[0052] In some embodiments, the plug-in device further includes a transformer, one end of which is electrically connected to the first end of the plug, and the other end of which is electrically connected to the second end of the plug. The second end of the plug is used to connect and cooperate with an external power source, facilitating the connection between the plug and the external power source.
