Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to an intelligent distribution box using a flexible connection. Background Technology

[0002] As the core equipment for power distribution and control, intelligent distribution boxes generally use rigid copper busbars to connect their internal circuit breakers and copper busbars.

[0003] Because the rigid copper busbar is rigidly connected to the circuit breaker, there is no buffer adjustment space. During the transportation of the intelligent distribution box, external forces such as vehicle bumps and vibrations can be directly transmitted to the circuit breaker's terminals through the rigid copper busbar, causing the internal contacts of the circuit breaker to loosen, the terminals to deform, and even damage to the core components of the circuit breaker, increasing product transportation losses and after-sales maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent distribution box with flexible connection to solve the problems existing in the prior art, reduce product transportation losses and after-sales maintenance costs, and improve product delivery reliability.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an intelligent distribution box with flexible connection, including a box body; multiple horizontal copper busbars are arranged vertically at intervals within the box body; multiple circuit breakers are arranged horizontally at intervals within the box body, and each circuit breaker is located below the lowest horizontal copper busbar; each circuit breaker is electrically connected to each horizontal copper busbar through a flexible connector; the flexible connector is flexibly deformable, one end of the flexible connector is electrically connected to the horizontal copper busbar, and the other end of the flexible connector is electrically connected to the terminal of the corresponding circuit breaker.

[0007] Preferably, a high-temperature resistant insulating sleeve is fixedly installed inside the housing at the position corresponding to each of the flexible connectors, and the flexible connector passes through the high-temperature resistant insulating sleeve and has a gap with the inner wall of the high-temperature resistant insulating sleeve.

[0008] Preferably, the high-temperature resistant insulating sleeve is a transparent tube.

[0009] Preferably, the high-temperature resistant insulating sleeve is provided with different markings corresponding to different terminals of the circuit breaker.

[0010] Preferably, the flexible connector is a busbar expansion joint.

[0011] Preferably, the two ends of the flexible connector are detachably connected to the horizontal copper busbar and the wiring terminals of the circuit breaker, respectively.

[0012] Preferably, an upper waist beam and a lower waist beam are fixedly installed inside the box; in the vertical direction, the lower waist beam is located below the upper waist beam; each circuit breaker is detachably fixedly installed on the upper waist beam and the lower waist beam respectively.

[0013] Preferably, the plurality of circuit breakers includes at least one main circuit breaker and at least two branch circuit breakers.

[0014] Preferably, each of the horizontal copper busbars is fixedly installed inside the box by at least one insulator.

[0015] Preferably, the number of horizontal copper busbars is four.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This utility model provides an intelligent distribution box with flexible connections. It features multiple horizontal copper busbars arranged vertically at intervals within the box, and multiple circuit breakers arranged horizontally at intervals below the lowest horizontal copper busbar. Flexible connectors are used to connect the circuit breakers to the horizontal copper busbars, significantly reducing transportation losses and after-sales maintenance costs, and improving product delivery reliability. During transportation, the flexible connectors absorb external forces generated by bumps and vibrations through their elastic deformation, blocking the transmission of rigid forces to the circuit breakers and preventing damage such as loose contacts and terminal deformation. They also adapt to installation deviations to eliminate secondary damage caused by stress accumulation, greatly reducing the circuit breaker transportation damage rate. The flexible connectors compensate for minor deformations of the copper busbars, ensuring on-site installation without secondary processing. They also absorb dimensional changes caused by thermal expansion and contraction of the copper busbars, preventing stress fatigue damage during long-term operation and ensuring convenient installation and long-term operational stability.
