[0028] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0030] As described above, the positive and negative poles are easily connected in reverse during the installation of the socket, such as a DC socket, and the structures of the positive and negative ports on the DC socket are similar. Although the positive and negative ports are marked, it is still difficult to avoid the reverse connection of the positive and negative poles. Once the reverse connection occurs, if the electrical device does not have a protection circuit, the electrical device will be damaged when connected, causing property loss and even threatening personal safety. The embodiment of the present disclosure provides a socket 100 to at least partially solve the above problem. In the following, Figures 1 to 5 The principles of the present disclosure are described.

[0031] Figure 1 A cross-sectional view of a socket 100 is shown according to some embodiments of the present disclosure. Figure 2 A bottom view of a socket 100 is shown in accordance with some embodiments of the present disclosure. Figure 3 A top view of a socket 100 is shown according to some embodiments of the present disclosure. Figure 4 FIG. 1 shows a circuit diagram of a socket 100 according to some embodiments of the present disclosure. Figures 1 to 4 As shown, the socket 100 described herein generally comprises a base 1, a printed circuit board 2, a diode 3, a signal control circuit 4, a step-down circuit 5, an indicator light 6, a light guide 7 and a cover 8. The socket 100 is a DC socket.

[0032] Continue reading Figures 1 to 4In some embodiments, the cover 8 covers the base 1. The printed circuit board 2 is disposed in the base 1. The diode 3, the signal control circuit 4, the step-down circuit 5 and the indicator light 6 can all be integrated on the printed circuit board 2, so that the diode 3, the signal control circuit 4, the step-down circuit 5 and the indicator light 6 are all disposed in the base 1.

[0033] refer to Figure 2 In some embodiments, the base 1 may include a positive wiring port 11 and a negative wiring port 12. The positive wiring port 11 is used to connect the positive pole of the DC power supply, and the negative wiring port 12 is used to connect the negative pole of the DC power supply. If the positive wiring port 11 is mistakenly connected to the negative pole of the DC power supply and the negative wiring port 12 is mistakenly connected to the positive pole of the DC power supply, the socket 100 will have the positive and negative poles reversely wired as described above.

[0034] refer to Figure 4 In order to avoid the reverse connection of the positive and negative poles, the positive pole of the diode 3 can be coupled to the negative pole wiring port 12. The signal control circuit 4 is coupled to the negative pole of the diode 3, and the signal control circuit 4 is coupled to the positive pole wiring port 11 to output a control signal when the diode 3 is turned on. The indicator light 6 is coupled to the signal control circuit 4 to work when receiving the control signal output by the signal control circuit 4.

[0035] With the above arrangement, if the positive wiring port 11 and the negative wiring port 12 are normally wired (i.e. not reversely wired), the two-wire connection 3 will be cut off, so that the signal control circuit 4 cannot obtain the working power supply, and thus will not output the control signal. In this case, the indicator light 6 will not work. On the contrary, if the positive wiring port 11 and the negative wiring port 12 are reversely wired, the two-wire connection 3 will be turned on, so that the signal control circuit 4 can obtain the working power supply, and thus can output the control signal to control the indicator light 6 to work.

[0036] According to the embodiment of the present disclosure, when the two-tube 3 is turned on, the signal control circuit 4 can control the indicator light 6 to work, thereby alerting the customer. In this way, after the customer observes that the indicator light 6 is working, he can change the wiring mode in time, thereby avoiding damage to the equipment and ensuring personal safety.

[0037] In addition, in the case of normal wiring, the indicator light 6 is not working, so as to avoid the indicator light 6 working and affecting the appearance of the socket 100.

[0038] Continue to refer Figure 4 In some embodiments, the step-down circuit 5 can be coupled between the cathode of the diode 3 and the signal control circuit 4. The step-down circuit 5 is mainly used to reduce the voltage, thereby reducing the voltage to a level suitable for the signal control circuit 4 to work.

[0039] The step-down circuit 5 according to the embodiment of the present disclosure may be any type of step-down circuit currently known or available in the future, as long as it can reduce the level of the DC voltage, and the embodiment of the present disclosure is not limited to this. For example, in some embodiments, the step-down circuit 5 may include a linear step-down circuit. In other embodiments, the step-down circuit 5 may include a step-down conversion circuit (Buck circuit).

[0040] Continue to refer Figure 4 In some embodiments, the signal control circuit 4 can output a pulse width modulation (PWM) signal to control the indicator light 6 to flash, wherein a high level signal can control the indicator light 6 to light up, and a low level signal can control the indicator light 6 to turn off. By controlling the indicator light 6 to flash, the operator can be reminded in time in the case of reverse wiring.

[0041] In some embodiments, when the positive and negative poles are connected in reverse, instead of the indicator light 6 flashing, the signal control circuit 4 can control the signal to make the indicator light 6 always on, so as to remind the operator in this way.

[0042] It should be understood that the signal control circuit 4 according to the embodiment of the present disclosure can be various types of signal control circuits currently known or available in the future, as long as it can control the indicator light 6 to work in an appropriate manner to issue an alarm, and the embodiment of the present disclosure is not limited to this.

[0043] Figure 5 A circuit schematic diagram of a signal control circuit 4 according to some embodiments of the present disclosure is shown. Figure 5 The signal control circuit 4 shown is a 555 monostable circuit. The 555 monostable circuit can work when receiving a voltage provided via a diode 3 or a step-down circuit 5, thereby outputting a PWM signal.

[0044] Specifically, if Figure 5 As shown, when the positive and negative poles of the socket are reversely connected, the voltage VCC is provided through the diode 3 or the step-down circuit 5 and the capacitor C2 is charged through the resistors R5 and R6. When the voltage of the capacitor C2 rises to 2 / 3VCC, the RS trigger (reset / set trigger) built into the 555 monostable circuit is set to 0, the 555 monostable circuit can output a low-level signal, and the indicator light 6 is off. At this time, the capacitor C2 is discharged through the transistor and resistor R6 built into the 555 monostable circuit. When the voltage of the C2 capacitor drops to <1 / 3VCC, the RS trigger built into the 555 monostable circuit is set to 1, that is, the 555 monostable circuit can output a high-level signal, and the indicator light 6 is on. In this way, the indicator light 6 is controlled to flash in a cycle.

[0045] In addition, the signal control circuit 4 may further include a micro control unit (MCU). The MCU can work when receiving a voltage provided by the diode 3 or the step-down circuit 5, thereby outputting a PWM signal, which will not be described in detail.

[0046] Return to reference Figure 1 In some embodiments, the light guide 7 can be disposed in the base 1 adjacent to the indicator light 6 , and the light guide 7 can extend to a position adjacent to the surface of the base 1 to conduct the light of the indicator light 6 .

[0047] The light guide 7 according to the embodiment of the present disclosure can be made of various types of materials currently known or available in the future, as long as it can achieve the transmission of light, and the embodiment of the present disclosure does not limit this. For example, in some embodiments, the material of the light guide 7 can be acrylic.

[0048] Continue to refer Figures 1 to 3 In some embodiments, a light-transmitting groove 81 may be provided on the side of the cover 8 facing the base 1. The end of the light guide 7 facing away from the indicator light 6 may be located in the light-transmitting groove 81. Thus, the customer can observe the light of the indicator light 6 more intuitively, thereby avoiding the risk of reverse wiring.

[0049] The anti-reverse wiring design according to the embodiment of the present disclosure can be applied to various DC sockets to at least partially solve the above problems. It should be understood that the anti-reverse wiring design according to the embodiment of the present disclosure can also be applied to other electrical components, and the embodiment of the present disclosure is not limited to this.
