Abstract
Description
Technical Field
[0001] This utility model relates to the field of plug technology, and in particular to a plug with an indicator light. Background Technology
[0002] A plug is the connector for electronic products and the pin for electrical appliances. During the use of an appliance, in order to obtain a normal power supply, the appliance's plug must be connected to a power outlet. Currently, there are plugs on the market with indicator lights. When the plug is inserted into the power outlet, the indicator light on the plug lights up, allowing for a more intuitive observation of whether the plug is connected to the power source. The indicator light consists of an LED and two pins connected to the LED. These two pins are respectively connected to the positive and negative power lines on the outlet (e.g., ...). Figure 1 As shown in the diagram, the plug can directly power the LED and make it light up after being inserted into the socket. However, the pins are small, making it difficult to connect to the power cord. The pins are also difficult to fix. In addition, after the connection is completed, the power cord, LED and plug need to be wrapped with injection molding. During the injection molding process, the material can easily break the pins and power cord apart or knock the indicator light off course. Positional deviations can easily lead to short circuits and other risks, increasing the risk of use. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] like Figures 2 to 6 As shown, a plug with an indicator light includes a housing 1, on which a power cord 2 is connected. The power cord 2 has three wires: a neutral wire, a live wire, and a ground wire. Inside the housing 1, there is a plug mounting plate 3, on which plugs 4 are fixedly mounted. Similarly, there are three plugs 4 arranged in a triangular structure. One end of each plug 4 is located inside the housing 1 and connected to the power cord 2. The three plugs 4 are respectively connected to the neutral wire, the live wire, and the ground wire. The other end of each plug 4 extends to the outside of the housing 1 and is connected to an external socket. The plug mounting plate 3 also has an indicator light circuit board 5, on which an indicator light 6 is provided. The indicator light 6 is an LED surface mount lamp bead. The indicator light circuit board 5 has a terminal block, which is connected to the plug 4.
[0028] In this invention, the indicator light 6 is first installed on the indicator light circuit board 5. As is common knowledge in the circuit board field, circuit boards have busbars for current flow. Therefore, the busbars on the indicator light circuit board 5 can connect to the indicator light 6, providing conductivity. The insert 4 is inserted into the insert mounting plate 3, which is made of PVC using injection molding. During the injection molding process, the insert 4 is placed in the injection mold. After the insert mounting plate 3 cools, the insert 4 is fixedly inserted onto it, with both ends of the insert 4 located on either side of the insert mounting plate 3. Then, the indicator light circuit board 5, on which the indicator light 6 is installed, is placed on the insert mounting plate 3, and the indicator light circuit board 5 and the insert 4 are fixedly connected by solder. Soldering is a simpler and more convenient method, facilitating the connection between the insert 4 and the indicator light circuit board 5. The solder is conductive and can cover the pins of the indicator circuit board 5. After the plug is inserted into the power supply, the current can be conducted from the pin 4 through the solder to the pins of the indicator circuit board 5 and finally to the indicator light 6, making the indicator light 6 light up. The solder can also firmly fix the indicator circuit board 5 to the pin mounting plate 3. Then the pin 4 is connected to the power cord 2. Finally, the housing 1 is made by injection molding. The housing 1 is made of PVC material and is transparent or semi-transparent after injection molding, so that the light can be transmitted to the outside. The injection-molded housing 1 can completely cover the pin mounting plate 3 and the indicator circuit board 5. The indicator circuit board 5 and the pin 4 are fixed by solder. Therefore, the housing 1 is not easily displaced by material impact during injection molding, which can avoid short circuits and improve the safety of the plug.
[0029] Furthermore, such as Figure 2 As shown, the side wall of the indicator circuit board 5 is provided with a positioning slot 7, and the insert 4 is inserted into the positioning slot 7. There are two positioning slots 7, so the two inserts 4 can be located in the two positioning slots 7 respectively. The two inserts 4 are respectively connected to the positive and negative terminals of the power line 2, thereby generating a current loop so that the indicator light can light up normally.
[0030] Furthermore, the indicator circuit board 5 is provided with a connecting piece 8, which covers the indicator circuit board 5 and is connected to the wire bar on the indicator circuit board 5. The connecting piece 8 is connected to the plug 4 by soldering. There are two connecting pieces 8, which are respectively connected to the wire bar on the indicator circuit board 5 that is connected to the positive and negative terminals of the indicator light 6. The two connecting pieces 8 are also connected to the plug 4 that connects to the positive and negative terminals of the power cord 2 by soldering. Therefore, after the plug is connected and inserted into the power socket, the power can be transmitted to the indicator light 6 in sequence through the plug 4, the connecting piece 8 and the wire bar on the indicator circuit board 5, so that the indicator light lights up. At the same time, the current can also be transmitted to the power cord 2 through the plug 4 to power the home appliance.
[0031] Furthermore, the indicator circuit board 5 is also provided with a surface mount resistor 9, which is located on the wire bar between the terminal block 8 and the indicator light 6. The surface mount resistor 9 can protect the indicator light 6 and prevent the indicator light from being damaged.
[0032] Furthermore, such as Figure 4 As shown, the insert 4 includes a plug-in portion 10 and a riveting portion 11 located at the upper end of the plug-in portion 10. The insert mounting plate 3 is connected to the plug-in portion 10. The upper end of the plug-in portion 10 extends above the upper surface of the insert mounting plate 3, and the lower end of the plug-in portion 10 extends below the lower surface of the insert mounting plate 3. The indicator light circuit board 5 is fixedly connected to the plug-in portion 10 of the insert 4 by soldering. The riveting portion 11 is connected to the power cord 2. The horizontal cross-section of the riveting portion 11 is a C-shaped structure. After the power cord 2 is inserted into the riveting portion 11, it is pressed and riveted so that the riveting portion 11 can clamp the power cord 2 and prevent the power cord 2 from falling off.
[0033] Furthermore, the insertion part 10 is provided with a first connection hole 12, which is located inside the insert mounting plate 3. The insert mounting plate 3 is provided with a plurality of second connection holes 13. Since both the insert mounting plate 3 and the housing are made by injection molding, during the injection molding process, a part of the insert mounting plate 3 can enter the first connection hole 12 to prevent the insert 4 from separating from the insert mounting plate 3. Similarly, a part of the housing 1 can enter the second connection holes 13 to prevent the insert mounting plate 3 from shaking inside the housing 1.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
