Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a universal junction box box. Background Technology

[0002] Cranes typically connect power lines, control lines, communication lines, sensor lines, and lighting lines. Some lines may contain multiple types; for example, sensors used on cranes include tension sensors, pressure sensors, strain gauge sensors, dynamic weighing sensors, load sensors, and height sensors. In addition, there are specific types of sensors such as pin sensors, pressure-side sensors, bearing seat sensors, and fishback sensors. Junction boxes are needed to distribute the wiring. However, cranes have numerous connectors requiring branching, and there are multiple installation methods, necessitating the fabrication of junction boxes of different specifications to meet these requirements. (See attached diagram.) Figure 1 The currently used universal junction box has multiple interfaces on the box, and then multiple partitions are set to separate and reinforce the box. Finally, it is sealed by filling with sealant. However, it has been found in use that the universal junction box can be used normally at room temperature, but in high temperature and low temperature environments, the sealant expands and contracts significantly, causing cracks and loss of sealing, resulting in product quality problems. Utility Model Content
