Description

Technical Field

[0001] This utility model relates to the field of busbar trunking, and more particularly to a waterproof busbar trunking. Background Technology

[0002] Busbar trunking is a busbar system consisting of a metal plate as a protective shell, conductive bars, insulating materials, and related accessories. It can be made into a plug-in type enclosed busbar with plug-in junction boxes at intervals, or a feeder type enclosed busbar without junction boxes in the middle. In some special environments, such as humid places or outdoors, the waterproof performance of busbar trunking is crucial.

[0003] Currently, busbar trunking on the market has some shortcomings in terms of waterproofing. For example, some busbar trunking has poor sealing performance at the connection points, which can easily lead to water seepage. Some busbar trunking also lacks internal drying measures, so even if no water enters directly, the moisture in the air may affect the insulation performance of the busbar trunking.

[0004] Therefore, those skilled in the art have provided a waterproof busbar trunking to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof busbar trunking. Through the cooperation of the first clamping plate, the second clamping plate, and the waterproof cover, moisture can be effectively prevented from entering the busbar trunking, thus improving the waterproof performance of the busbar trunking. The waterproof cover is slidably connected to the busbar trunking body, and the cooperation between the movable block and the square groove makes the installation and disassembly of the waterproof cover convenient and quick.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A waterproof busbar trunking includes a busbar trunking body, one end of which is provided with a connector, and the other end of which is provided with a connector hole. A first vent hole is formed at the top of the busbar trunking body. A connecting plate is connected to the top of the busbar trunking body, and a rectangular groove is formed at the top of the connecting plate. A rectangular block is connected to the connecting plate, and a cover plate is connected to the rectangular block. Bolts are connected to the cover plate. A T-shaped groove is formed on one side of the connecting plate, and a desiccant placement box is connected to the T-shaped groove. A second vent hole is formed on the desiccant placement box. Two vents; a slot is provided at one end of the busbar trunking body; sliding grooves are provided on both sides of the busbar trunking body; a first locking plate is connected to one end of the busbar trunking body; a first spring is connected to one side of the first locking plate; a limit plate is connected to one end of the first spring; a second locking plate is connected to one end of the busbar trunking body; movable grooves are provided on both sides of the busbar trunking body; a second spring is connected inside the movable groove; a movable block is connected to one end of the second spring; a waterproof cover is connected to the busbar trunking body; and a square groove is provided on the waterproof cover.

[0008] Through the above technical solution, the cooperation of the first clamping plate, the second clamping plate, and the waterproof cover can prevent moisture from entering the busbar trunking.

[0009] Furthermore, the plug is fixedly connected to one end of the busbar trunking body, the plug hole is fixedly connected to the other end of the busbar trunking body, and the first vent hole is evenly distributed on the top of the busbar trunking body.

[0010] Through the above technical solution, the evenly distributed first vent holes can more effectively promote air circulation inside the busbar trunking, which helps to dissipate heat and maintain the stability of the internal air environment, preventing component aging or failure caused by poor air circulation.

[0011] Furthermore, the connecting plate is symmetrically fixedly installed on the top of the busbar trunking body, the rectangular block is fixedly connected to the cover plate, the rectangular block is consistent with the shape of the rectangular trunking and fits tightly, and the bolt is threadedly connected to the cover plate and the connecting plate;

[0012] Through the above technical solution, the symmetrically installed connecting plates make the installation of the cover plate more balanced and stable. The tight fit between the rectangular block and the rectangular groove, as well as the threaded connection of the bolts, can firmly fix the cover plate to the busbar trunking body, which can play a good protective role for the conductive components inside the busbar trunking, prevent foreign objects from entering and dust from accumulating, and also facilitate disassembly operations during inspection and maintenance.

[0013] Furthermore, the desiccant placement box has T-shaped ends, which correspond to the T-shaped groove. The desiccant placement box is slidably connected to the connecting plate, and the second vent holes are evenly distributed at the bottom of the desiccant placement box.

[0014] Through the above technical solution, the T-shaped design at both ends of the desiccant placement box allows it to fit tightly with the T-shaped groove and achieve a sliding connection, which facilitates the installation and replacement of the desiccant. The evenly distributed second vent holes allow the desiccant to fully contact the air inside the busbar trunking, effectively absorbing moisture and maintaining a dry environment inside the busbar trunking. This improves the insulation performance and service life of the busbar trunking and reduces the risk of electrical faults caused by moisture.

[0015] Furthermore, the card slot is symmetrically arranged on the left and right sides near the insertion hole, the sliding groove is symmetrically arranged on the left and right sides near the insertion hole, and a limit groove is formed on the right side of the sliding groove;

[0016] Through the above technical solution, the symmetrically arranged slots and sliding grooves provide precise positioning and guidance for the connection between busbar trunking, making the connection between the connector and the plug hole more accurate and convenient. The opening of the limiting groove can limit the components during the connection process, preventing them from sliding or misaligning, ensuring the stability and reliability of the busbar trunking connection structure, and helping to improve the overall electrical connection performance.

[0017] Furthermore, the first card plate is fixedly connected to the busbar trunking body, the first card plate is tightly fitted to the card slot, one end of the first spring is fixedly connected to the first card plate, the limiting plate is fixedly connected to the other end of the first spring, and the second card plate is fixedly connected to the busbar trunking body.

[0018] Through the above technical solution, the tight fit between the first card plate and the card slot, as well as the setting of the first spring and the limiting plate, can provide a certain elastic pressure when the busbar trunking is connected, making the connection tighter and preventing the connection from loosening due to vibration or other reasons. The second card plate further enhances the structural strength and stability of the connection part, ensuring the reliability of the busbar trunking connection during operation and reducing the possibility of electrical accidents caused by connection problems.

[0019] Furthermore, the movable slots are symmetrically arranged on both sides near the plug connector, one end of the second spring is fixedly connected to the busbar trunking body, and the movable block is fixedly connected to the other end of the second spring;

[0020] Through the above technical solution, the symmetrically arranged movable groove, second spring and movable block constitute an elastic structure, which provides elastic support for the installation and fixation of the waterproof cover. When the waterproof cover is installed, the movable block can be tightly matched with the corresponding structure on the waterproof cover under the action of the second spring to ensure the sealing effect of the waterproof cover. At the same time, when subjected to external impact or vibration, the elastic structure can play a buffering role, protect the waterproof cover and the busbar trunking body, and extend their service life.

[0021] Furthermore, the waterproof cover is slidably connected to the busbar trunking body, the square groove is symmetrically opened on both sides of the waterproof cover, and the shape of the movable block is consistent with the square groove;

[0022] Through the above technical solution, the sliding connection between the waterproof cover and the busbar trunking body makes the installation and disassembly of the waterproof cover simple and convenient. The square groove and the movable block have the same shape and cooperate with each other, which can accurately fix the waterproof cover on the busbar trunking body, ensuring the stability of the waterproof cover position, thereby effectively preventing water from entering the busbar trunking, improving the waterproof performance of the busbar trunking, and enabling it to operate safely and reliably in humid or rainy environments.

The second retaining plate 19 further enhances the stability of the connection, ensuring a reliable electrical connection during busbar trunking operation. When the internal air humidity of the busbar trunking is high, a desiccant is released through... The second vent 12 absorbs moisture, keeping the inside of the busbar trunking dry, improving insulation performance, and reducing the risk of electrical faults caused by moisture. The cover plate 8 and the connecting plate 5 are threaded together by bolts 9, thus forming a protective structure for the inside of the busbar trunking, preventing foreign objects from entering and dust from accumulating, and protecting the internal conductive components. When the waterproof cover 23 is installed, it slides along the busbar trunking body 1. The square grooves 24 symmetrically opened on both sides of the waterproof cover 23 are consistent with the shape of the movable block 22. During the sliding process, the movable block 22 gradually slides into the square groove 24 under the elastic action of the second spring 21 until the waterproof cover 23 reaches the appropriate position. At this time, the movable block 22 and the square groove 24 fit tightly together, firmly fixing the waterproof cover 23 on the busbar trunking body 1, effectively blocking moisture from entering the inside of the busbar trunking and improving waterproof performance.
