AI Technical Summary
Existing cable tie fasteners have low clamping strength and lack a three-layer interlocking structure, resulting in insufficient stability and reliability in complex environments. They are prone to loosening and wear, increasing maintenance costs.
A three-layer stable locking tongue structure was designed, including a cable tie body, a locking tongue, an inner body, a tongue buckle, a snap fastener, a filling block, and an inner locking block. The three-layer design enhances the locking effect. The snap fastener and the tongue buckle interlock with each other, and the inner locking block and the tongue buckle fit tightly together, providing additional support to prevent loosening.
It improves the overall strength and impact and vibration resistance of the locking tongue, ensures a tight connection between the cable tie and the locking tongue, prevents loosening or detachment due to vibration or impact, and enhances the stability and reliability of the wire harness system.
