Description

Technical Field

[0001] This utility model belongs to the field of busbar connector technology, specifically, it relates to a waterproof busbar connector. Background Technology

[0002] Busbars connect the various current-carrying branch circuits in a power distribution system, playing a role in collecting, distributing, and transmitting electrical energy. Based on their shape and structure, busbars are broadly classified into three categories: rigid busbars, including rectangular busbars, circular busbars, and tubular busbars. Busbar joints are mostly connected by plug-in connections. Bus trunking is also very common in daily life; it is a closed metal device made of copper or aluminum busbar columns, used to distribute larger amounts of power to various components in a distributed system.

[0003] Publication No. CN218633241U discloses a waterproof busbar trunking connector, including mounting plates. A first waterproof hemisphere is movably mounted on the outer surface of one mounting plate, and a second waterproof hemisphere is movably mounted on the outer surface of the other mounting plate. Two drainage plates are installed on the upper and lower ends of both the first and second waterproof hemispheres. This invention, through the cooperation of the first and second waterproof hemispheres, allows the device to be used such that, after the mounting plate and conductive copper plate are installed between the copper busbars on both sides, a fixing rod can be inserted into the mounting rod, causing the first and second waterproof hemispheres to be mounted on the outer surface of the mounting plate. This, in turn, provides a blocking effect through the first and second waterproof hemispheres, thus isolating the connection between the copper busbars and the conductive copper plate, thereby achieving a waterproof function.

[0004] Many existing busbar connections are exposed to the outside environment. Although some busbar connections are waterproof, they are still susceptible to rainwater erosion over time, which can affect their service life and even cause short circuits.

[0005] To address the aforementioned issues, this application proposes a waterproof busbar connector. Utility Model Content
