This material provides a superior base.
Each connector features a double U-shaped design, intended for parallel wire insertion and crimping. The dimensions provided, such as 15mm length, 5.8mm width, and 6.4mm height for one variant, and 14.8mm length, 4.4mm width, and 4.3mm height for another, indicate a compact form factor suitable for various applications. The U-shape is distinct.
This double U-shaped geometry is specifically designed to provide enhanced wire retention and strain relief. When properly crimped, the terminal securely grips the conductor and often the insulation, preventing accidental disconnections due to vibration or tension. This design minimizes stress on the wire itself.
Compared to single-crimp spade terminals, the double U-design offers a more encompassing grip on the wire. This reduces the likelihood of the wire pulling out, a common failure point with less robust terminal designs. It is a more secure method.
