Precision Design for Robust Connections

WEIPU clamping-nut components are designed to lock cables firmly to circular, heavy-duty, and CEE-style connectors. Available in multiple thread sizes and materials, each nut focuses on repeatable torque control, consistent clamping force, and long-term wear resistance. Typical features include anti-rotation profiles, integrated sealing faces compatible with O-rings or gaskets, and tamper-resistant options for secure installations.

Material and Finish Options

Choose from engineered plastics, nickel-plated brass, and stainless steel to match electrical, mechanical, and environmental needs. Chemical-resistant polymers provide low-conductivity, lightweight solutions for medical devices, while metal variants offer superior mechanical strength for rail and heavy machinery. Surface treatments and corrosion-resistant finishes ensure long service life in IP-rated assemblies.

FAQ:

What should I pay attention to when installing the ST Series connectors?

When installing, first ensure that the cable outer diameter matches 5-8mm; second, when soldering, control the soldering temperature and time to avoid damaging the PPS insert due to high temperature; finally, ensure that the threaded coupling is fully tightened to ensure the IP67 waterproof and dustproof performance. It is recommended to follow the official installation manual for operation.

How to select the appropriate protection level for Weipu Combined Distribution?

It is recommended to select based on the actual application environment: 1) Indoor/semi-outdoor environments with general dust and splashing water: IP44-IP54; 2) Outdoor environments with heavy rain and strong dust: IP65-IP67; 3) Environments with long-term immersion or extreme corrosion: IP68. Our technical team can also provide customized selection suggestions based on specific scene details.

Is the TYPR-231-C connector compatible with other models of Weipu waterproof connectors?

The TYPR-231-C series has a standard interface size and locking mechanism. Under the premise of consistent rated parameters and pin configuration, it can be compatible with some universal industrial connectors of the same specification. For the best use effect, it is recommended to use Weipu original matching connectors.
