Description

Technical Field

[0001] This utility model relates to the field of junction boxes, specifically a leaky cable junction box. Background Technology

[0002] During use, especially outdoors or in harsh environments, the surface of the leaky cable is an uneven cylindrical shape with two grooves. Existing junction boxes use layers of tape to wrap around the cable for waterproofing, but the waterproofing effect is not good in actual applications. If the waterproofing is not long enough, water will seep into the joints. This will not only affect the normal use of the cable, but may also damage the electrical components inside the cable, thereby affecting the stability and safety of the entire system. Therefore, we provide a leaky cable junction box to solve the above problems. Utility Model Content

Two mounting bolts are installed on the outer surface of the heater.

[0006] As a further embodiment of this utility model: a sensor box is installed on the inner wall of the wire box body, and the end of the sensor probe away from the IoT smart temperature and humidity controller extends through the sensor box and into the interior of the sensor box.

[0007] As a further improvement of this utility model: the input end of the vacuum pump is connected to an input pipe, and the end of the input pipe away from the vacuum pump passes through the sensor box and extends into the interior of the sensor box.

[0008] As a further improvement of this utility model: two sealing gaskets are installed on the outer surface of the junction box body, and two leaky cable bodies are provided inside the junction box body.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] This invention utilizes an IoT-based intelligent temperature and humidity controller and sensor probe to detect when the humidity inside the connector exceeds a set threshold. When this occurs, a heater is activated to transfer heat into the connector, raising the dew point and increasing the evaporation rate of any liquid water present. This helps prevent condensation caused by excessive humidity and avoids standing wave problems. A vacuum pump, in conjunction with a one-way normally closed solenoid valve, extracts high-humidity air to ensure the leaky cable maintains a normal operating environment. This helps keep the leaky cable dry, preventing corrosion or short circuits of electrical components and improving overall stability and safety. Attached Figure Description

[0022] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0023] A leaky cable junction box includes a box body 1. A fixing plate 9 and a connecting plate 16 are installed inside the box body 1. A one-way pressure valve is provided on the outer surface of the box body 1 to release pressure outwards and maintain a relatively stable internal air pressure. Multiple fixing screws 10 are installed on the outer surface of the fixing plate 9, and multiple connecting screws 17 are installed on the outer surface of the connecting plate 16. A switching power supply 11 is installed on the outer surface of the fixing plate 9. Terminal blocks 12 are installed on the outer surface of the switching power supply 11. An IoT smart temperature and humidity controller 13 is installed on the outer surface of the switching power supply 11. A transmission... A vacuum pump 18 is mounted on the outer surface of the sensor probe 14 and the connecting plate 16. The output end of the vacuum pump 18 passes through the junction box body 1 and is fitted with a one-way airtight valve 7. The one-way airtight valve 7 can release pressure to maintain a relatively stable internal air pressure. This one-way pressure release prevents moisture and dust from the external environment from being drawn into the enclosure. A heater 24 is installed inside the junction box body 1. The junction box body 1 is made of polycarbonate material. Boxes made of this material have excellent electrical insulation, thus providing high waterproof and dustproof capabilities. Furthermore, compared to ordinary plastic materials, it has excellent resistance to corrosive liquids such as seawater, oil, and gasoline. In addition, the enclosure made of this material is high-strength, wear-resistant, high-temperature resistant, anti-aging, and low-temperature resistant.

[0024] In this embodiment, two mounting blocks 22 are installed on the inner wall of the junction box body 1. The outer surfaces of the two mounting blocks 22 are connected to the outer surface of the heater 24. Two mounting bolts 23 are installed on the outer surface of the heater 24. Through the cooperation of the mounting blocks 22 and the mounting bolts 23, the heater 24 can be supported and made more stable during use.

[0025] In this embodiment, a sensor box 15 is installed on the inner wall of the junction box body 1, and the end of the sensor probe 14 away from the IoT smart temperature and humidity controller 13 extends through the sensor box 15 and into the interior of the sensor box 15.

[0026] In this embodiment, the input end of the vacuum pump 18 is connected to an input pipe 19, and the end of the input pipe 19 away from the vacuum pump 18 passes through the sensor box 15 and extends into the interior of the sensor box 15.

[0027] In this embodiment, two sealing gaskets 8 are installed on the outer surface of the junction box body 1, and two leaky cable bodies 5 are provided inside the junction box body 1. The sealing gaskets 8 can fit tightly with the grooves on the surface of the leaky cable body 5, which has the advantage of better sealing effect.

[0028] In this embodiment, the outer surface of the leaky cable body 5 is engaged with the outer surface of the sealing gasket 8 through a groove, and the outer surface of the junction box body 1 is provided with two locking bolts 6.

[0029] In this embodiment, the two leaky cable bodies 5 are installed with a leaky cable connector 21 at their close ends. The outer surface of the leaky cable connector 21 is connected to a connecting pipe 20. The end of the connecting pipe 20 away from the leaky cable connector 21 passes through the sensor box 15 and extends into the interior of the sensor box 15.

[0030] In this embodiment, a plurality of mounting pads 3 are installed on the outer surface of the junction box body 1, and mounting screws 4 are installed on the outer surface of each mounting pad 3. A sealing door 2 is installed on the outer surface of the junction box body 1. The mounting pads 3 and mounting screws 4 enable the device to be wall-mounted. The screw holes are relatively independent from the interior to ensure its sealing.

[0031] Working principle: When the sensor probe 14 detects that the humidity is greater than the preset humidity value or the temperature is lower than the preset temperature value, the heater 24 starts to work. This prevents the internal temperature from being too low or the humidity from being too high, which would cause condensation and affect the normal operation of the leaky cable, resulting in standing wave problems. When the humidity reaches the set humidity threshold while the heater 24 is heating, in order to prevent the humidity from exceeding the threshold again in a short period of time and to prevent the equipment from being repeatedly started in a short period of time, thus reducing its service life, the heater 24 will continue to heat until the humidity is lower than the set value. Similarly, when the temperature reaches the set temperature threshold, the heater 24 will continue to heat until the temperature is higher than the set value. Then, the vacuum pump 18 is started in conjunction with the one-way airtight valve 7 to extract the high humidity air, so as to ensure that the inside of the leaky cable body 5 reaches the normal working environment.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
