1.Dual-Spring Contact Mechanism
The KF550H employs a dual-spring clamping structure to establish the electrical connection with the conductor:When a wire is inserted into the terminal, the upper and lower sets of springs make contact with the conductor and generate a clamping force, thereby creating a multi-point contact;
This structure enhances contact reliability and vibration resistance, while also helping to minimize fluctuations in contact resistance;
Once the connection is established, the internal springs within the terminal maintain a stable clamp on the conductor; under normal operating conditions, no secondary crimping or soldering is required.
2.Is Tool-Free Wiring Supported?
Regarding the “tool-free” wiring stage: Typically, no soldering is required; the connection is completed simply by stripping the wire according to specifications and inserting it directly into the terminal entry.
3.Do Tools Are Required for Unlocking or Wire Removal?
When wire removal or maintenance is required:
The terminal typically requires an unlocking action to release the clamping force of the spring clip.
Unlocking methods include: pressing, inserting a tool into the unlocking port, or using a dedicated unlocking tool.
It is strongly advised against forcibly pulling out the wire without first unlocking the terminal, to prevent damage to the spring clip or the conductor.
