Description

Technical Field

[0001] This utility model relates to the field of power socket technology, and in particular to an AC socket and its water ingress detection system. Background Technology

[0002] Power sockets generate alternating current when in operation. During daily use, especially outdoors, power sockets are susceptible to rain or water immersion. If water enters a power socket while it is energized, there is a significant risk of damage to the socket and other safety hazards such as sparking. Currently, when AC sockets are submerged in water or water enters the wiring holes, the detection method typically only involves detecting the direct current between the electrode pins inside the AC socket. However, if the water ingress does not simultaneously affect both electrode pins, this method is insufficient for accurately and effectively determining the extent of water damage. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 The first aspect of this utility model provides an AC socket, including a housing 12, a live wire pin 1, a neutral wire pin 2, a ground pin 3, and at least one water ingress detection pin 4;

[0034] The live wire pin 1, the neutral wire pin 2, the grounding pin 3, and the water ingress detection pin 4 are all assembled inside the housing 12. The water ingress detection pin 4 is positioned close to the live wire pin 1, the neutral wire pin 2, or the grounding pin 3, and there is a gap between the water ingress detection pin 4 and the live wire pin 1, the neutral wire pin 2, or the grounding pin 3.

[0035] Specifically, typically, the distance between the live wire pin 1, neutral wire pin 2, and ground pin 3 in an AC socket is relatively large. Therefore, when the AC socket experiences water ingress, especially a small amount, the water may not simultaneously reach both pins, preventing the formation of a conductive circuit. This can lead to the assumption that no water has entered the AC socket, resulting in inaccurate and ineffective water ingress detection. Therefore, this embodiment places a water ingress detection pin 4 near the live wire pin 1, neutral wire pin 2, or ground pin 3 within the AC socket. Compared to the distance between different pins, the distance between the water ingress detection pin 4 and the nearest pin is smaller, making it easier to form a conductive circuit when water ingress occurs. This allows for more accurate and effective water ingress detection of the AC socket. For example, the number of water ingress detection pins 4 in this embodiment can be 1, 2, 3, or 4, etc. This embodiment does not impose a specific limitation; the water ingress detection pin 4 can be placed near one of the pins.

[0036] As a preferred embodiment, the housing 12 is provided with a first accommodating cavity 6 for assembling the live wire pin 1, a second accommodating cavity 7 for assembling the neutral wire pin 2, and a third accommodating cavity 8 for assembling the grounding pin 3; the water ingress detection pin 4 is disposed in the first accommodating cavity 6, the second accommodating cavity 7, or the third accommodating cavity 8.

[0037] It is worth noting that, in this embodiment, the live wire pin 1, neutral wire pin 2, and ground pin 3 are located in different accommodating cavities. As a result, the distance between the live wire pin 1, neutral wire pin 2, and ground pin 3 is not only relatively large, but also separated from each other due to the internal structure of the AC socket. This makes it difficult to easily form a conductive circuit between the two electrode pins when water ingress occurs. Therefore, in this embodiment, the water ingress detection pin 4 is further located in the first accommodating cavity 6, the second accommodating cavity 7, or the third accommodating cavity 8, so that the water ingress detection pin 4 and one of the electrode pins are in the same accommodating cavity. This not only ensures that the distance between the water ingress detection pin 4 and one of the electrode pins is small, but also that they are not separated from each other. Thus, when water ingress occurs, it is easy to form a conductive circuit between the water ingress detection pin 4 and one of the electrode pins, thereby enabling more accurate and effective water ingress detection of the AC socket.

[0038] In one alternative embodiment, such as Figure 2 As shown, there is one water ingress detection pin 4, which is installed in the first accommodating cavity 6. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the live wire pin 1, thereby enabling effective detection of water ingress.

[0039] In one alternative embodiment, such as Figure 3 As shown, there is one water ingress detection pin 4, which is installed in the second accommodating cavity 7. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the neutral wire pin 2, thereby enabling effective detection of water ingress.

[0040] In one alternative embodiment, such as Figure 4 As shown, there is one water ingress detection pin 4, which is installed in the third accommodating cavity 8. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the grounding pin 3, thereby enabling effective detection of water ingress.

[0041] In one alternative embodiment, such as Figure 5 As shown, there are two water ingress detection pins 4, one of which is installed in the first accommodating cavity 6 and the other is installed in the second accommodating cavity 7. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the live wire pin 1, and between the water ingress detection pin 4 and the neutral wire pin 2, thereby enabling effective detection of water ingress.

[0042] In one alternative embodiment, such as Figure 6As shown, there are two water ingress detection pins 4, one of which is installed in the first accommodating cavity 6 and the other is installed in the third accommodating cavity 8. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the live wire pin 1, and between the water ingress detection pin 4 and the grounding pin 3, thereby enabling effective detection of water ingress.

[0043] In one alternative embodiment, such as Figure 7 As shown, there are two water ingress detection pins 4. One of the water ingress detection pins 4 is installed in the second accommodating cavity 7, and the other water ingress detection pin 4 is installed in the third accommodating cavity 8. When water ingress occurs, a conductive loop can be easily formed between the water ingress detection pin 4 and the neutral wire pin 2, and between the water ingress detection pin 4 and the grounding pin 3, thereby enabling effective detection of water ingress.

[0044] In one alternative embodiment, such as Figure 8 As shown, there are 3 water ingress detection pins 4, and these 3 water ingress detection pins 4 are respectively installed in the first accommodating cavity 6, the second accommodating cavity 7 and the third accommodating cavity 8. When water ingress occurs, it is easy to form a conductive circuit between the water ingress detection pin 4 and the live wire pin 1, between the water ingress detection pin 4 and the neutral wire pin 2, and between the water ingress detection pin 4 and the grounding pin 3, so as to achieve effective detection of water ingress.

[0045] As a preferred embodiment, the housing 12 has at least one cavity 5, which is located near the live wire pin 1, the neutral wire pin 2 or the ground pin 3, and the water ingress detection pin 4 is located in the cavity 5.

[0046] It is worth noting that, in this embodiment, the housing 12 has at least one cavity 5 located near the live wire pin 1, neutral wire pin 2, or ground pin 3. This is to prevent the water ingress detection pin 4 and the electrode pin from being located in the same cavity, which could lead to easy contact and cause the AC socket to malfunction. At the same time, it is necessary to ensure that a conductive circuit can be easily formed between the water ingress detection pin 4 and one of the electrode pins when water ingress occurs. In this embodiment, the water ingress detection pin 4 is located in the aforementioned cavity 5. Since these cavities 5 are located near at least one electrode pin, the distance between the water ingress detection pin 4 and the electrode pin is obviously smaller than the distance between different electrode pins, making it easier to form a conductive circuit with one of the electrode pins when water ingress occurs in the AC socket.

[0047] In one alternative embodiment, such as Figure 9As shown, there is one water ingress detection pin 4, which is installed in the cavity 5 near the live wire pin 1. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the live wire pin 1, thereby enabling effective detection of water ingress.

[0048] In one alternative embodiment, such as Figure 10 As shown, there is one water ingress detection pin 4, which is installed in the cavity 5 near the neutral pin 2. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the neutral pin 2, thereby enabling effective detection of water ingress.

[0049] In one alternative embodiment, such as Figure 11 As shown, there are two water ingress detection pins 4, one of which is installed in the cavity 5 near the live wire pin 1 and the other is installed in the cavity 5 near the neutral wire pin 2. When water ingress occurs, a conductive circuit can be easily formed between the water ingress detection pin 4 and the live wire pin 1, and between the water ingress detection pin 4 and the neutral wire pin 2, thereby enabling effective detection of water ingress.

[0050] It is worth noting that when the number of water inlet detection pins 4 is greater than one, some water inlet detection pins 4 and electrode pins may be located in the same accommodating cavity, while some water inlet detection pins 4 may be located in a cavity 5 near one of the electrode pins. This embodiment does not uniformly limit the setting method of each water inlet detection pin 4.

[0051] As a preferred embodiment, the distance between the water inlet detection pin 4 and the live wire pin 1, the neutral wire pin 2, and the grounding pin 3 is greater than or equal to 0.5 mm.

[0052] Specifically, to prevent the AC socket from malfunctioning due to contact between the water ingress detection pin 4 and the electrode pins, this embodiment further limits the distance between the water ingress detection pin 4 and the live wire pin 1, neutral wire pin 2, and ground pin 3 to be greater than or equal to 0.5mm. For example, the distance can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, etc. This embodiment does not make a specific limitation here, thereby ensuring that the distance between the water ingress detection pin 4 and each electrode pin is large enough to effectively prevent the water ingress detection pin 4 from contacting any of the electrode pins.

[0053] As a preferred embodiment, the outer shell 12 is provided with a first drain hole 9 that connects to the first accommodating cavity 6, a second drain hole 10 that connects to the second accommodating cavity 7, and a third drain hole 11 that connects to the third accommodating cavity 8.

[0054] Specifically, such as Figure 12As shown, this embodiment further provides a first drain hole 9, a second drain hole 10, and a third drain hole 11 in the first accommodating cavity 6, the second accommodating cavity 7, and the third accommodating cavity 8, respectively. It can be understood that the first drain hole 9, the second drain hole 10, and the third drain hole 11 are all connected to the outside, so that when water enters, the water inside the AC socket can be quickly discharged through the first drain hole 9, the second drain hole 10, or the third drain hole 11, avoiding the continuous immersion of water inside the AC socket and causing serious damage.

[0055] As a preferred embodiment, the outer shell 12 is provided with a fourth drainage hole that communicates with the cavity 5.

[0056] Specifically, in this embodiment, a fourth drain hole is provided in the cavity 5 near the electrode pin. When the AC socket is exposed to water, the water will not only flow into the cavity where the electrode pin is located, but may also flow into the nearby cavity 5. If it is not drained in time, it will cause safety hazards. Therefore, the fourth drain hole can drain the water flowing into the cavity 5 in time when water is exposed, and further prevent the AC socket from being continuously soaked in water and causing serious damage.

[0057] As a preferred embodiment, the housing 12 includes a base 101 and a rear cover 102; the live wire pin 1, the neutral wire pin 2, the grounding pin 3, and the water ingress detection pin 4 are all assembled inside the base 101, and the base 101 is provided with a first socket corresponding to the live wire pin 1, a second socket corresponding to the neutral wire pin 2, and a third socket corresponding to the grounding pin 3; the rear cover 102 is located at the bottom of the base 101, and the rear cover 102 is provided with a plurality of through holes for the live wire pin 1, the neutral wire pin 2, the grounding pin 3, or the water ingress detection pin 4 to pass through.

[0058] Specifically, such as Figure 12 and Figure 13 As shown, the outer casing 12 in this embodiment specifically includes a base 101 and a rear cover 102. The base 101 has a first accommodating cavity 6 for mounting the live wire pin 1, a second accommodating cavity 7 for mounting the neutral wire pin 2, and a third accommodating cavity 8 for mounting the grounding pin 3. The rear cover 102 is located at the bottom of the base 101, and the rear cover 102 has several through holes for the live wire pin 1, neutral wire pin 2, grounding pin 3, or water ingress detection pin 4 to pass through. Thus, one end of the live wire pin 1, neutral wire pin 2, grounding pin 3, and water ingress detection pin 4 will protrude from the rear cover 102, which facilitates the connection of AC power supply with the live wire pin 1, neutral wire pin 2, and grounding pin 3, and facilitates the connection of the controller used to detect water ingress with the live wire pin 1, neutral wire pin 2, grounding pin 3, and water ingress detection pin 4.

[0059] As a preferred embodiment, the first socket is provided with a first movable component, the second socket is provided with a second movable component, and the third socket is provided with a third movable component.

[0060] Specifically, in this embodiment, a first movable component, a second movable component, and a third movable component are respectively provided at the first socket, the second socket, and the third socket. When the load plug is not inserted into the AC socket, the first movable component, the second movable component, and the third movable component will block the first socket, the second socket, and the third socket respectively, thereby preventing external water from entering the first socket, the second socket, and the third socket. When the load plug is inserted into the AC socket, the first movable component, the second movable component, and the third movable component will move and expose the first socket, the second socket, and the third socket, so that the load plug can be inserted into the AC socket and connected to the live wire pin 1, the neutral wire pin 2, and the ground pin 3.

[0061] As a preferred embodiment, the water inlet detection pin 4 is made of metal.

[0062] The AC socket provided in this embodiment of the utility model has at least one water ingress detection pin 4 in the outer casing 12, and the water ingress detection pin 4 is set close to the live wire pin 1, neutral wire pin 2 or ground pin 3. So when the AC socket encounters water ingress, the live wire pin 1, neutral wire pin 2 or ground pin 3 will form a conductive circuit with the water ingress detection pin 4 through the water. By injecting an electrical signal, the water ingress status of the current AC socket can be accurately and effectively determined.

[0063] Please see Figure 14 The second aspect of this utility model provides a water ingress detection system for an AC socket, including an AC power supply 14, a controller 13, and an AC socket as described in any embodiment of the first aspect;

[0064] The output terminal of the AC power supply 14 is connected to the live wire pin 1, neutral wire pin 2 and ground pin 3 of the AC socket respectively. The live wire pin 1, the neutral wire pin 2, the ground pin 3 and the water inlet detection pin 4 are connected to the signal port of the controller 13. The control terminal of the controller 13 is connected to the controlled terminal of the AC power supply 14.

[0065] Specifically, in this embodiment, the output terminal of the AC power supply 14 is connected to the live wire pin 1, neutral wire pin 2, and ground pin 3 of the AC socket, respectively, so that the load can be powered when the load plug is inserted into the AC socket. In addition, by connecting the live wire pin 1, neutral wire pin 2, ground pin 3, and water ingress detection pin 4 to the signal port of the controller 13, the water ingress status of the AC socket can be determined by injecting an electrical signal. It can be understood that when it is necessary to detect whether there is water ingress, the controller 13 can apply an independent detection signal to one of the electrode pins (live wire pin 1, neutral wire pin 2, or ground pin 3) or the water ingress detection pin 4 through the signal port. For example, an isolated DC electrical signal can be applied. If there is water ingress, there must be at least one conductive loop between the water ingress detection pin 4 and its nearby electrode pin. The controller 13 can determine whether there is a conductive loop in the AC socket by judging whether it can receive the independent detection signal from the signal port. If so, it is determined that there is water ingress in the AC socket. For example, suppose a water ingress detection pin 4 is set near the live wire pin 1. In order to detect whether there is water ingress in the current AC socket, the controller 13 applies an independent detection signal to the live wire pin 1 (or water ingress detection pin 4) and detects whether the independent detection signal is received from the water ingress detection pin 4 (or live wire pin 1). If so, it is determined that a conductive loop has been formed between the current live wire pin 1 and the water ingress detection pin 4, that is, there is water ingress in the AC socket.

[0066] Furthermore, the control terminal of the controller 13 is connected to the controlled terminal of the AC power supply 14, so that when the controller 13 detects water ingress in the AC socket, the controller 13 can send a stop power supply signal to the controlled terminal of the AC power supply 14 through the control terminal, so that the AC power supply 14 stops supplying power to the AC socket; when the controller 13 detects that there is no longer water ingress in the AC socket, the controller 13 sends a restore power supply signal to the controlled terminal of the AC power supply 14 through the control terminal, so that the AC power supply 14 resumes supplying power to the AC socket.

[0067] The water ingress detection system for AC sockets provided in this embodiment of the invention has at least one water ingress detection pin 4 inside the housing of the AC socket, and the water ingress detection pin 4 is located close to the live wire pin 1, neutral wire pin 2 or ground pin 3. When the AC socket encounters water ingress, the live wire pin 1, neutral wire pin 2 or ground pin 3 will form a conductive circuit with the water ingress detection pin 4 through the water. By injecting an electrical signal, the water ingress status of the current AC socket can be accurately and effectively determined.

[0068] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
