Ugreen UG- 70683 Crimping Tool
The UGREEN UG-70683 is a professional-grade multi-function crimping tool engineered for terminating network and telecommunication cables. This precision instrument combines three essential functions in a single tool body: crimping, cutting, and wire stripping. The device accommodates both RJ45 and RJ11 connectors, making it suitable for Ethernet and telephone cable installations.
Multi-Connector Crimping Capability
The UG-70683 features dedicated crimping dies for multiple connector types. The tool crimps 8P8C (RJ45) connectors used in Cat5, Cat5e, Cat6, and Cat6a Ethernet cables. Additionally, it handles 6P6C (RJ11), 6P4C, and 6P2C connectors commonly found in telephone systems. The crimping mechanism applies uniform pressure across all contact points, ensuring reliable electrical connections.
The ratcheting mechanism prevents premature release during the crimping cycle. This feature guarantees complete compression of connector pins onto conductors before the tool releases. Consequently, each termination achieves consistent contact resistance and mechanical stability. The ratchet system also reduces hand fatigue during repetitive crimping operations.
Integrated Wire Processing Functions
Built-in cutting blades slice through twisted pair cables cleanly without fraying individual conductors. The hardened steel blades maintain sharpness through thousands of cuts. Moreover, the cutting section handles cable diameters up to 6mm, accommodating standard Cat5e and Cat6 cables with various jacket thicknesses.
Dedicated wire stripping slots remove cable jackets at two common positions. The stripping section features precisely sized openings that cut through outer insulation without damaging inner conductor pairs. Furthermore, the tool includes separate stripping notches for individual wire gauges, enabling clean removal of conductor insulation when necessary.
Ergonomic Construction and Durability
The UGREEN UG-70683 incorporates high-carbon steel construction in critical load-bearing components. The crimping dies undergo heat treatment to achieve hardness ratings suitable for professional-grade applications. This metallurgical treatment prevents die deformation even after thousands of crimping cycles.
Non-slip rubber grips cover approximately 60% of the handle surfaces. These cushioned areas distribute hand pressure evenly, reducing operator fatigue during extended use. The ergonomic handle design positions the operator’s hand at an optimal angle for maximum leverage with minimum effort.
The tool measures approximately 200mm in overall length, providing sufficient leverage for complete crimping force without excessive size. The compact dimensions allow storage in standard tool pouches while maintaining comfortable two-handed operation. Additionally, the tool weighs approximately 280 grams, balancing substantial construction with portable handling.
Precision Alignment System
A built-in connector positioning guide ensures proper alignment before crimping begins. This guide centers RJ45 and RJ11 connectors within the crimping dies, preventing off-axis compression that could damage connector housings or create unreliable pin contact. The transparent positioning window allows visual verification of wire insertion depth before crimping.
Wire sequence verification becomes simpler through the clear connector holder. Technicians can confirm proper color code arrangement (T568A or T568B standards) before committing to the crimp. This visual inspection step reduces termination errors and minimizes waste of connectors and cable.
