Connector With Reinforcing Plate And Low-Rigidity Portion

A strain relief member is introduced as an intermediary component between the flat cable and the connection terminals. This member absorbs and distributes the pulling force, preventing it from being directly transmitted to the fixing parts. The strain relief member acts as a buffer that protects the connection interface while still allowing the cable to be pulled rearward, thus resolving the contradiction between reliability and force resistance.

The strain relief member is designed to provide cushioning protection before the pulling force can damage the connection terminals. By positioning this protective element in advance between the cable and the terminals, the system prepares for potential pulling forces and absorbs them before they reach the vulnerable fixing parts, preventing unstable connection states and detachment.

The strain relief member is integrated with the existing insulating sheet of the flat cable through lamination or bonding, merging two functional elements into a single composite structure. This approach provides both reinforcement and strain relief functionality without adding separate discrete components, thus improving strength while minimizing the increase in device complexity.

The insulating sheet is given multiple functions: it continues to provide electrical insulation while also serving as a substrate for the strain relief member, which provides both structural reinforcement and strain relief. This multi-functional design avoids adding unnecessary components and reduces overall device complexity while achieving the desired strength improvement.
