Technical Field
[0001] This utility model relates to the field of connectors, and in particular to connectors with a sealed and shock-absorbing integrated structure. Background Technology
[0002] Connectors are crucial components in the new energy field. They are typically composed of mating plug and socket modules. To prevent foreign objects from entering the connector components, the mating interface requires a sealed structure. Simultaneously, to ensure safe and stable operation, a shock-absorbing structure is also needed. Currently, connectors employ two structures to achieve both sealing and shock absorption functions. However, this approach has several drawbacks: First, the current structure requires numerous components to perform both functions, increasing manufacturing costs. Second, both structures necessitate corresponding mounting structures on the connector housing, complicating the overall design and requiring more space. Third, the assembly process is complex and cumbersome, resulting in low efficiency and a high risk of assembly defects, further increasing assembly costs. Utility Model Content
