A plug-in power supply structure for a busbar bridge

Abstract

This utility model discloses a plug-in power supply structure for a busbar bridge, belonging to the field of compact busbar trunking. The plug-in power supply structure includes a compact busbar trunking unit one and a compact busbar trunking unit two. The compact busbar trunking unit one includes a protective shell, inside which several identical busbars are fixedly installed. Each busbar has a C-shaped plug-in end and a U-shaped plug-in end at both ends. This structure achieves this by integrally bending the square structure at both ends of a traditional busbar into a C-shaped plug-in end and a U-shaped plug-in end. This allows for direct plug-in connection between the two compact busbar trunking units when they are joined, completing the initial fixing and limiting at the connection point. This facilitates subsequent positioning and installation work and improves the stability of the connection structure.

Description

Technical Field

[0001] The utility model relates to the field of intensive bus ducts, and more specifically, to a plug-in power-taking structure of a bus bridge. Background Art

[0002] A busbar bridge is usually a bridge-shaped power transmission structure composed of several dense busbar ducts connected end to end. Therefore, in order to facilitate the end-to-end connection between several dense busbar ducts, the busbars at both ends of the existing dense busbar ducts are usually set to a square structure with a relatively simple shape and structure, and the square structure is provided with through holes for convenient bolt connection. When plugging in and taking power, the busbars between the two adjacent dense busbar ducts overlap, and then the bolts are penetrated and tightened to complete the installation and plug-in power process. Although such a structure is relatively convenient to install, after the busbars between the two adjacent dense busbar ducts overlap, there is a lack of corresponding limiting structure between the ends of the corresponding two plug-in busbars, which is not conducive to the smooth docking and installation of the corresponding two busbars. Therefore, we propose a plug-in power-taking structure for a busbar bridge to solve the above-mentioned problems. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a plug-in power supply structure for a busbar bridge, which bends the square structures at both ends of the traditional busbar row into a C-shaped C-type plug-in end and a U-shaped U-shaped plug-in end, so that when the two corresponding dense busbar ducts are docked, the ends can be directly plugged in through the C-shaped plug-in end and the U-shaped plug-in end, completing the initial fixed limit of the connection, thereby facilitating the subsequent positioning and installation work and improving the stability of the connection structure; and the connection between the C-shaped plug-in end and the U-shaped plug-in end is further supported by expansion bolts, so that the arc-shaped portion of the C-shaped plug-in end is firmly stuck inside the arc-shaped portion of the U-shaped plug-in end, thereby improving the stability of the connection structure and reducing the risk of poor contact or false connection.

Several busbars 5 with the same structure are fixedly installed inside the protective shell 4. The busbars 5 are respectively provided with C-shaped plug-in terminals 6 and U-shaped plug-in terminals 7 at both ends. The compact busbar duct 1 and the compact busbar duct 2 are connected through the corresponding U-shaped plug-in terminals 7 and C-shaped plug-in terminals 6. Expansion bolts 3 are clamped inside the C-shaped plug-in terminals 6 at the connection between the U-shaped plug-in terminals 7 and the C-shaped plug-in terminals 6.

[0027] The installation process of the plug-in power supply structure of this busbar bridge is as follows:

[0028] First, fix the dense bus duct 1 on the wall, and then use the C-type plug-in end 6 to insert the dense bus duct 2 into the U-type plug-in end 7 of the dense bus duct 1. At this time, fix the dense bus duct 2 on the wall to form a complete plug-in power supply structure of the bus bridge. Then insert the expansion bolts 3 into the C-type plug-in end 6 at the connection of several C-type plug-in ends 6 and U-type plug-in ends 7, and then use a wrench to tighten the locking nuts 304 on the corresponding expansion bolts 3, so that it drives the expansion rod 302 to be pulled out, and then gradually pushes it into the inside of the expansion tube 301 through the conical convex end 303, thereby achieving the effect of expanding the expansion tube 301 and expanding the arc-shaped part of the C-type plug-in end 6, so that the arc-shaped part of the C-type plug-in end 6 can be firmly stuck in the arc-shaped part of the U-shaped plug-in end 7, thereby improving the stability of the connection structure and reducing the phenomenon of false connection at the connection.

[0031] By fixing a group of conical convex ends 303 at one end of the expansion rod 302, a group of supporting structures are provided inside the expansion tube 301, thereby increasing the expansion support area of ​​the expansion tube 301, thereby increasing the support area of ​​the inner wall of the arc portion of the C-shaped plug end 6, and making the arc portion of the C-shaped plug end 6 more evenly contacting the inner arc portion of the U-shaped plug end 7.
