In harsh environments such as industrial automation, rail transit and new energy, circular connectors serve as core components for signal transmission and power connection. Thread locking is a critical factor that determines connection stability and service life.
During on-site installation, many users face the same issue: over-tightening threads for higher fastening force causes housing cracking, internal core displacement and insulation damage, eventually leading to poor contact, failed IP protection, or even direct product scrapping.
This problem is rarely caused by operational errors, but by uneven stress distribution of traditional locking structures. Local stress concentration will be transmitted to precision internal cores once over-tightened, resulting in permanent damage.
To solve this industry pain point, Octopusconn equips the full series of industrial circular connectors with a balanced thread locking structure. It effectively avoids damage caused by excessive tightening at the design level, balancing locking firmness and product safety.
Conventional circular connectors adopt simple thread engagement designs with obvious defects during locking:
Uneven circumferential force: Stress concentrates on one side of the housing, easily causing deformation and cracking;
Unprotected internal cores: Locking force directly impacts conductive cores and causes terminal misalignment;
Degraded protection: Core displacement breaks sealing structure and weakens IP67 waterproof and dustproof performance;
Shortened service life: Repeated improper installation reduces long-term industrial reliability.
With 13 years of connector R&D experience and a professional R&D team of over 20 experts, Octopusconn has optimized the thread locking system, focusing on uniform stress distribution and internal core protection:
Full-series models including M5, M8, M9, M12, M16 and 7/8 adopt standardized precision thread profiles to ensure uniform circumferential engagement, eliminate local stress and prevent housing compression deformation.
The connector housing is made of high-strength engineering plastic or metal with reinforced stress areas, distributing locking torque evenly across the shell and isolating impact force from internal insulation components.
The built-in limiting structure stops rotation at standard torque to eliminate over-tightening. Even untrained operators can complete installation without damaging housings or internal cores.
Certified by EN60529 (IP67), EU LVD, FCC and other authoritative standards, our connectors deliver stable structural strength and industrial-grade safety for long-term operation.
The balanced thread locking structure is fully applied to Octopusconn mainstream circular connectors to meet diversified industrial installation demands:
Core Series: M12/M16 connectors (ideal for Industrial Ethernet, PROFINET and EtherCAT systems);
Compact Series: M5/M8/M9 connectors (for miniature automation equipment and sensors);
High-Current Series: 7/8 circular connectors (for energy management and power transmission);
Full Product Coverage: Overmolded plugs, field-assemblable plugs, sockets and custom harness assemblies.
Widely applied in automated production lines, rail transit, new energy, medical equipment, food & beverage and other industries, our connectors enable worry-free installation and long-term stable connection performance.
The value of industrial connectors lies not only in basic connection, but in long-term stability and durability.
