Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive busbars, and in particular to a copper-aluminum composite conductive busbar. Background Technology
[0002] Chinese patent CN219979760U discloses a copper-aluminum composite connecting busbar, including a main aluminum busbar and a connector copper busbar. The connector copper busbar is plugged into and welded to the main aluminum busbar. At the plugging point of the main aluminum busbar and the connector copper busbar, one is provided with a slot and the other is provided with a plug block adapted to the slot. The slot and the plug block form a plugging structure. The connector copper busbar has a through-hole for installing bolts.
[0003] In the above structure, the copper busbar of the connector and the aluminum busbar of the main body are connected to each other by first plugging and then welding. If the above connecting busbar is used in a place where vibration is frequently generated, the weld between the copper busbar of the connector and the aluminum busbar of the main body will be gradually damaged due to vibration because the copper busbar of the connector is directly connected to the aluminum busbar of the main body by welding. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies where the welded joint between the copper busbar and the main aluminum busbar is rigidly connected by welding, and the welded joint gradually becomes damaged due to vibration. It provides a copper-aluminum composite conductive busbar with a buffer structure.
[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0006] A copper-aluminum composite conductive busbar includes a main aluminum busbar and connecting copper busbars respectively disposed at both ends of the main aluminum busbar. A flexible connecting section with conductivity and buffering vibration force is fixed between the main aluminum busbar and the connecting copper busbars.
[0007] By adopting the above solution, the main aluminum busbar and the connecting copper busbar are connected by a flexible connecting section. This allows the conductive busbar to absorb the vibration generated during use in environments where vibration is frequent, thereby reducing the vibration at the fixing points between the flexible connecting section and the main aluminum busbar, and between the flexible connecting section and the connecting copper busbar. This makes the connection between the flexible connecting section and the main aluminum busbar, and between the flexible connecting section and the connecting copper busbar, more stable. At the same time, when the position of the component connected to the connecting copper busbar shifts, the flexible connecting section can drive the position of the connecting copper busbar relative to the main copper busbar, allowing the connecting copper busbar to still be connected to the component to be connected, thus improving the applicability of the guide busbar.
[0008] Preferably, the flexible connection segment is a copper conductor.
[0009] Preferably, protective components are provided at the connection points between the copper conductor and the main aluminum busbar, as well as between the copper conductor and the connecting copper busbar, to reduce the probability of electric shock.
[0010] Preferably, the protective component includes an insulating sleeve fitted at the connection between the copper conductor and the main aluminum busbar, and a protective sleeve fitted at the connection between the copper conductor and the connecting copper busbar. The protective sleeve extends to cover the surface of the connecting copper busbar, and the protective sleeve is provided with a socket that is aligned with the mounting hole on the connecting copper busbar and allows bolts to pass through.
[0011] By adopting the above solution, the insulating sleeve installed at the connection between the copper conductor and the main aluminum busbar can wrap the connection between the two, thereby reducing the probability of the user coming into contact with the connection and reducing the risk of electric shock. The protective sleeve installed at the connection between the copper conductor and the connecting copper busbar can reduce the probability of the user coming into direct contact with the connection between the copper conductor and the connecting copper busbar, reducing the risk of electric shock. The protective sleeve extending to the surface of the connecting copper busbar can reduce the probability of the user connecting to the connecting copper busbar, thereby further reducing the risk of electric shock.
[0012] Preferably, the protective cover includes an upper snap-fit cover, a lower snap-fit cover, and a snap-fit assembly for snapping the two together.
[0013] Preferably, the fastening assembly includes at least one fastening protrusion on the two side walls of the upper fastening cover and fastening grooves on the two side walls of the lower fastening cover for the fastening protrusion to be inserted.
[0014] With the above solution, the fastening protrusions on both sides of the upper fastening cover can be inserted into the fastening grooves on both sides of the lower fastening cover when the lower fastening cover is fastened onto the upper fastening cover, thereby achieving the fastening between the upper and lower fastening covers, which facilitates the installation of the protective sleeve onto the connecting copper busbar and copper wire.
[0015] Preferably, the end of the fastening protrusion away from the upper fastening cover is provided with an inlet ramp to facilitate its insertion into the fastening groove.
[0016] Using the above solution, the guide slope set on the fastening protrusion can abut against the side wall of the lower fastening cover when the lower fastening cover is fastened to the upper fastening cover, thereby driving the side wall of the lower fastening cover to deform, so that the fastening protrusion can be inserted into the fastening groove more easily.
[0017] This utility model, by adopting the above technical solution, has significant technical effects: By connecting the main aluminum busbar and the connecting copper busbar with a flexible connecting section, the conductive busbar absorbs the vibrations generated during use in environments where vibration is frequent. This reduces the vibration at the fixing points between the flexible connecting section and the main aluminum busbar, and between the flexible connecting section and the connecting copper busbar, making the connection between the flexible connecting section and the main aluminum busbar, and between the flexible connecting section and the connecting copper busbar, more stable. Furthermore, when the position of the component connected to the connecting copper busbar shifts, the flexible connecting section can move the connecting copper busbar relative to the main copper busbar, allowing the connecting copper busbar to still connect to the required component, thereby improving the applicability of the guide busbar.
