Wire Cover With Notched Groove For Stable Binding Band Mounting
Solution Overview
Problem
Existing wire covers for connectors complicate the mounting and stabilization of binding bands, leading to insecure fastening of wires due to the need for inserting band portions through holes and lack of a pressing mechanism, resulting in unstable binding work.
Innovation Solution
A wire cover design featuring a hood with a notched groove and deficient portions that guide the binding band's flexible band portion through specific paths, allowing easy mounting and stable fastening by pressing the head portion against the groove, ensuring secure wire fixation without protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If insertion holes are provided in the electric-wire fixing portion for binding bands with head portions, then the binding band can be inserted and fastened, but the mounting work becomes complicated and the binding work becomes unstable
Solution Approach 1:
The invention removes the insertion hole from the electric-wire fixing portion, extracting the complicating element. Instead, a groove is formed on the outer peripheral surface of the fixing portion, allowing the binding band to be simply hooked without insertion operations, thereby simplifying the mounting process while maintaining secure fastening capability
Solution Approach 2:
Instead of providing holes for insertion (inward opening), the invention uses a groove structure (outward opening) on the outer peripheral surface. This inverts the traditional approach from insertion-based mounting to hooking-based mounting, eliminating the need for complex insertion operations through holes
2Reliability
If no pressing portion is provided for the head portion of the binding band, then the structure remains simple, but the binding work becomes unstable and the wire cannot be fixed securely
Solution Approach 1:
The invention merges the groove structure with the outer peripheral surface of the electric-wire fixing portion, combining the guiding function and the pressing function into a single integrated structure. The groove serves both to guide the binding band during mounting and to provide a pressing surface for stable fastening, eliminating the need for separate pressing portions
Solution Approach 2:
The groove on the outer peripheral surface serves multiple functions: it guides the binding band during mounting, provides a hooking surface for secure attachment, and acts as a pressing portion for stable fastening. This multi-functional design achieves reliable binding without increasing structural complexity

AI summary
A wire cover includes a hood top surface, a first hood side surface and a second hood side surface. A hood side notched groove is formed in the first hood side surface so as to be notched from a tip edge toward a base end of the first hood side surface while leaving the base end. A hood side deficient portion is formed in the second hood side surface. The hood side deficient portion is deficient extending from a tip edge to a base end of the second hood side surface. A hood top surface deficient portion is formed in the hood top surface and is partially deficient of the hood top surface positioned near the second hood side surface. The hood top surface deficient portion is adjacent to the hood side deficient portion.
