Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection structures, in particular to a multi-connection combined board. Background Art

[0002] In modern industrial production, the normal operation of operating machines usually depends on the coordinated work of hydraulic and electrical systems. However, connecting the hydraulic pipes and electrical lines on the operating machines with the corresponding external pipes and lines has always been a challenging problem. Especially when it comes to the operation and maintenance of complex mechanical equipment, such as construction machinery, automated production lines, heavy equipment and other fields, hydraulic systems and electrical control systems are two key components to ensure the efficient and safe operation of equipment. These systems are usually composed of a large number of hydraulic pipes and electrical lines, which are responsible for transmitting power, control signals and data communications. The stability and reliability of their connections are directly related to the working performance and safety of the entire equipment.

[0003] In traditional ways, the connection of hydraulic pipelines and electrical lines often relies on on-site customized installation, which is often complicated in operation and requires professional personnel to install and debug. Not only is the installation process cumbersome and time-consuming, but once the equipment is upgraded or repaired, it is time-consuming and laborious to re-layout the pipelines and lines, which can easily lead to production interruptions and increase maintenance costs. At the same time, there are differences in operating machines of different models and specifications and the corresponding external pipelines and lines. The existing connection devices have poor versatility and cannot meet the connection requirements of various machines and lines. In addition, due to the dense and complex layout of hydraulic pipelines and electrical lines, incorrect connections or cross-interference may cause system failures or even safety accidents, seriously affecting production efficiency and safety. Traditional connection methods have many defects. For example, the connection of hydraulic pipelines may not be strong enough, which is prone to leakage and affects the performance of the hydraulic system; the connection of electrical lines may not be stable enough, which can easily lead to poor contact or line failure.

[0004] In summary, in order to improve the efficiency, reliability and versatility of the connection between the operating machine and the external hydraulic and electrical pipelines, it is particularly important to develop a multi-connection combination plate. This combination plate should be able to achieve fast and firm connection, and at the same time have good versatility and scalability to adapt to different operating machines and working environments. The multi-connection combination plate can connect multiple quick connectors of various specifications, and can simultaneously realize the rapid connection or disconnection of multiple groups of hydraulic connectors, avoiding the operator's passive manual connection alone, which can effectively save time and avoid the risk of the operator mistakenly connecting the wrong pipeline, especially for the agricultural field, construction field, industrial equipment and vehicles, etc. Utility Model Content
