Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, and more particularly to a waterproof and efficient heat dissipation junction box. Background Art

[0002] Junction boxes are essential components in power systems and electronic equipment, and are widely used in the power industry. They protect, secure, and connect wires, ensuring the safe transmission and distribution of electrical energy. Existing junction boxes have poor waterproofing during use. Because the boxes have wire holes on both sides, one end of the wire to be connected must be inserted through the holes into the box and then secured to the terminal blocks. When water enters the box between the holes and the wires, it can easily cause a short circuit, increasing safety risks. Secondly, when current passes through the terminals and connecting wires during use, the conductor's inherent resistance and the resistance at the connection point convert energy into heat, generating significant heat within the box. When the temperature inside the box rises, the insulation performance of the wires may degrade, increasing the risk of failure. Prolonged exposure to high temperatures can accelerate the aging of wires, reducing their service life. Utility Model Content

[0031] In this embodiment, one end of the wire to be connected is passed through the wire threading hole 4 and then fixed to the terminal 3 in the lower shell 1 to complete the connection of the wire.

The two first sealing strips 11 form a sealing ring, thereby sealing between the clamping plate 10 and the wire. At the same time, the two clamping plates 10 drive the two second sealing strips 12 to move, so that the two second sealing strips 12 form a sealing ring, thereby sealing between the clamping plate 10 and the lower shell 1 and between the connecting wire and the wire threading hole 4.

[0032] More specifically, by turning the handle 7, the two first sealing strips 11 seal between the two clamping plates 10 and the wires, while the second sealing strip 12 seals between the clamping plates 10 and the lower housing 1, and between the connecting wires and the threading holes 4. Throughout the use of the junction box, heat generated internally is directed to the two heat sinks 13 and the multiple heat dissipating fins 14, thereby achieving efficient heat dissipation.

[0034] Specifically, when the upper shell 2 is installed on the lower shell 1, the heat-conducting cover 16 will cover the terminal block 3. During the entire use of the junction box, the heat generated at the terminal block 3 will be introduced into the multiple first heat-conducting bars 15 through the heat-conducting cover 16, and then introduced into the heat dissipation plate 13 and the heat dissipation fins 14 of the upper shell 2 for dissipation. The heat at the lower end of the terminal block 3 will be introduced into the heat-conducting plate 17, and then introduced into the heat dissipation plate 13 and the heat dissipation fins 14 of the lower shell 1 through the multiple second heat-conducting bars 18 for dissipation.

[0035] See also Figure 1-5 , as an implementation method for sealing the upper shell 2 and the lower shell 1: a sealing ring 19 is fixedly provided at the lower end of the upper shell 2, and a sealing groove 20 that cooperates with the sealing ring 19 is provided on the lower shell 1; a plurality of mounting tubes 21 are fixedly provided on the upper shell 2, and each mounting tube 21 has a movable hole 22 at the upper and lower ends thereof respectively; a fixing bolt 23 is movably provided in the mounting tube 21, and the lower end of the fixing bolt 23 is threadedly connected to a mounting seat 24 through the movable hole 22; and the mounting seat 24 is fixedly provided on the outer side of the lower shell 1.

Turn the screwdriver so that the screwdriver drives the fixing bolt 23 to rotate.

[0037] In summary, when the overall equipment is in use:

[0038] When it is necessary to use a junction box to connect the wires to be connected, one end of the wire to be connected is passed through the wire hole 4 and then fixed to the terminal 3 in the lower shell 1 to complete the connection of the wires. The two turning handles 7 are rotated in sequence. The turning handle 7 drives the turning rod 6 to rotate, and the turning rod 6 drives multiple bidirectional threaded areas 8 to rotate. The bidirectional threaded areas 8 drive the two movable seats 9 of the threaded connection to move, and the movable seat 9 drives the clamping plate 10 to move. The clamping plate 10 drives the first sealing strip 11 and the second sealing strip 12 to move. With the cooperation of the two clamping plates 10, the connected wire is clamped between the two first sealing strips 11 between the two clamping plates 10. The two first sealing strips 11 form a sealing ring, thereby sealing between the clamping plate 10 and the wire. At the same time, the two clamping plates 10 drive the two second sealing strips 12 to move, so that the two second sealing strips 12 form a sealing ring, thereby sealing between the clamping plate 10 and the lower shell 1 and between the connecting wire and the wire hole 4.

[0039] When it is necessary to fix the upper shell 2 to the lower shell 1, place the upper shell 2 on the lower shell 1, and insert the sealing ring 19 into the sealing groove 20, insert one end of the screwdriver into the movable hole 22 above the mounting tube 21 and into the fixing bolt 23, turn the screwdriver so that the screwdriver drives the fixing bolt 23 to rotate, and the lower end of the fixing bolt 23 passes through the movable hole 22 at the lower end of the mounting tube 21 and is threadedly connected to the mounting seat 24, thereby fixing the mounting tube 21 and the mounting seat 24 together, and the upper shell 2 can be fixed to the lower shell 1.

[0040] When the junction box is in use and needs to be cooled, the heat shield 16 covers the terminal blocks 3 during the installation of the upper shell 2 onto the lower shell 1. During the entire use of the junction box, the heat generated at the terminal blocks 3 is directed through the heat shield 16 to the multiple first thermally conductive bars 15, and then to the heat sink 13 and heat fins 14 of the upper shell 2 for dissipation. The heat at the lower end of the terminal blocks 3 is directed to the heat shield 17, and then to the heat sink 13 and heat fins 14 of the lower shell 1 for dissipation. The heat sink 13 and heat fins 14 are made of copper and have extremely high thermal conductivity. The first thermally conductive bars 15, heat shield 16, heat shield 17, and second thermally conductive bars 18 are all made of ceramic, which is resistant to high temperatures, has good chemical stability, and excellent insulation properties.
