Description

TECHNICAL FIELD

[0001] The utility model relates to bus duct technical field more specifically, the utility model relates to a kind of connecting structure of high-efficiency heat dissipation type bus duct. BACKGROUND

[0002] Bus duct is a kind of closed metal device formed by copper and aluminum bus column, used to distribute large power for each element of dispersion system. In the indoor low-voltage power transmission trunk line engineering project, it has been more and more replaced by wire and cable. The existing bus duct is mostly provided with barbs on the cover plate and the bottom plate during insertion, and then the connecting plate is inserted into the inside of the barbs. The side plate of the bus duct is pressed by screws on the connecting plate to prevent it from falling off. The process is complicated, which increases unnecessary labor burden for users. At the same time, the contact resistance and temperature rise at the insertion part are generally high, and the heat dissipation performance is often difficult to guarantee.

[0003] In order to solve the above problems, through retrieval, a bus duct connecting structure with publication number CN210041239U is disclosed. The bolt column structure of two half edges is used to form a complete bolt column structure, and then the connecting part of the bus duct is fixed by the lock nut and the connecting box, which strengthens the connection strength and facilitates installation. The cross-sectional shape of the connecting box is matched with the bus duct, and the side surface is provided with a reinforcing plate, which enhances the mechanical strength and increases the heat dissipation area, thereby reducing the temperature rise of the connecting part.

[0004] For the above-mentioned bus duct connecting structure, the applicant found that the bolt column structure of two half edges can be fixed by screwing the nut after assembling a complete bolt column, but in actual application, the strength of the half-edge bolt column structure is not good. Even if the half-edge bolt column is fixed by welding, deformation or collapse may occur during transportation after manufacturing. Even slight deformation can cause the bolt to be unable to match and install, affecting the connection. Therefore, a replaceable bus duct connecting structure needs to be designed to solve this problem. UTILITY MODEL CONTENTS
