Description

Technical Field

[0001] The invention belongs to the technical field of junction boxes, and in particular relates to a junction box for an energy-saving electric power supply device. Background Art

[0002] The junction boxes currently used in the market for power supply lines usually do not have a good heat dissipation structure. The heat dissipation method of the junction box mainly depends on the heat dissipation structure inside the junction box shell. This type of heat dissipation structure is usually composed of a motor and fan blades, and does not have a good energy-saving effect. When the motor drives the fan blades to work, external air can enter the inside of the junction box. When the external air absorbs the heat inside the junction box, the fan blades drive the air inside the junction box to be discharged;

[0003] However, the size of the junction box is small, and the electrical structures inside the junction box are densely distributed. When the motor drives the fan blades to work, it can only drive part of the heat inside the junction box to be discharged, and it is difficult to achieve complete volatilization of the heat inside the junction box. When the fan blades drive the outside air into the interior of the junction box, the dust in the outside air is also easy to contact the electrical structures inside the junction box. Therefore, the staff needs to maintain the junction box regularly. In order to facilitate the installation of the junction box, the junction box is usually not equipped with a wire bracket. The wires installed on the junction box need to be fixed with the help of an external line. The external line support structure can indeed have a good fixing effect on the wires, but the external line support structure is not convenient for use with the junction box, which can easily cause the connection between the wires and the junction box to shake, resulting in poor contact at the connection end of the wires, and it is also easy to cause the connection part of the junction box to heat up.

[0004] Therefore, the existing junction box cannot meet the needs in actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the invention

[0032] When the staff installs the first plate seat 5 and the second plate seat 10 at the appropriate position, the outside air can enter the interior of the air guide hole 22, and the paddles 16 can transport the outside air to the interior of the exhaust duct 23. At this time, the outside air can flow on the surface of the first plate seat 5 and the second plate seat 10, so that the heat on the first plate seat 5 and the second plate seat 10 can be quickly evaporated. Since the paddles 16 are evenly spaced inside the air guide hole 22, and the exhaust ducts 23 are distributed on the outside of the first plate seat 5 and the second plate seat 10 close to the paddles 16, the heat on the first plate seat 5 and the second plate seat 10 can be evenly dissipated, so that the junction box can have a better energy-saving and heat dissipation effect.

When the exhaust motor 32 draws external air into the interior of the air guide hole 22 through the exhaust fan blades 27, the blades 16 can transport the external air to the interior of the exhaust duct 23. At this time, the external air flows on the first plate seat 5 and the second plate seat 10, which can achieve the first The heat on the first plate seat 5 and the second plate seat 10 evaporates quickly, so that the junction box has a better energy-saving and heat dissipation effect.
