Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a bus duct end connector. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] As a "trunk-type tappable high-current conductor" that replaces traditional wires and cables for transmitting electrical energy, dense busbar ducts are widely used in places with huge load demands, such as industrial plants, high-rise buildings, commercial complexes and rail transit, helping users achieve long-term, safe and stable power supply.

[0004] The overall size of a dense bus duct is limited, and usually multiple dense bus ducts need to be connected during use to meet the needs. The performance of the end connectors of the dense bus duct directly affects the performance and safety of the entire dense bus duct. Therefore, those skilled in the art provide a bus duct end connector to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a bus duct end connector, including a protective assembly, a pull plate, and a telescopic rod. The top side walls of the protective assembly are both provided with telescopic rods, and the two telescopic rods include a pull rod and a fixed rod;

[0006] One end of the fixing rod is arranged inside the protection assembly, and the other end of the fixing rod extends out of the protection assembly and is connected to one end of the pull rod;

[0007] The other end of the pull rod is fixedly connected to the pull plate. The pull plate is set to be L-shaped, with the concave surface of the pull plate facing the inside of the protective assembly, and the width of the pull plate is smaller than the distance between the two protective plates. The pull plate can be placed between the protective plates.

[0008] Preferably, an insulating plate is provided in the middle of one end of the two pull plates, and the insulating plate is configured to be cuttable.

[0009] Preferably, the bottom of the protective component is provided with a plurality of through holes, and the plurality of through holes are symmetrically distributed along the longitudinal axis of the protective component.

[0010] Preferably, a fixing sleeve is provided at the bottom end of the protective component, and a fixing screw is provided on the fixing sleeve.

[0011] Preferably, the protection assembly is arranged at the upper end of the protection plate, and the protection plate is arranged on both sides of the bus duct body.

[0012] Preferably, a conductor plate is provided on the inner side of the protective plate, the conductor plates are provided on both sides of the bus duct body, and the two bus duct bodies are connected through the conductor plates, and a protective component is provided to protect the connection parts of the conductor plates.

[0013] Preferably: the bus duct body adopts a dense plug-in bus duct. The dense bus duct has a compact structure, occupies a small installation space, and is more energy-saving and power-saving than cables.

[0014] Preferably, the insulating plate is made of a rubber-type insulating material, which can effectively isolate the current and prevent the current from leaking through the surface of the material.

[0015] The technical effects and advantages of this utility model are:

[0016] The conductor plates are arranged on both sides of the bus duct body, and the conductor plates of the two bus duct bodies are connected. The protective plates are arranged on both sides of the bus duct body. The protective components are sleeved on the protective plates and wrap the entire protective plates. The insulating plates are arranged to protect the connection parts of the conductor plates. At the same time, the setting of the insulating plates can ensure that dust and debris from above are isolated to avoid entering the connection parts of the conductor plates and causing accidents such as short circuits and poor contact.

[0017] After the two conductor plates are connected, the length of the telescopic rod is adjusted according to the distance between the conductor plates after connection, thereby changing the distance between the pull plates. The appropriate length of the insulating plate is cut according to the distance between the pull plates to ensure that the insulating plate can fit the size of the connection part of the conductor plates with fewer gaps.
