Cable Connector Locking Portion Hollow Cross Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors experience durability issues due to wear of locking projections made of plastic engaging with metal support fitting members, leading to reduced operational durability and increased size to enhance strength, which compromises connector size and efficiency.
Innovation Solution
A cable connector with a housing featuring locking portions with a hollow cross-sectional shape, allowing stress dispersion without abrasion, enhancing locking portion strength, reducing thickness, and ensuring reliable FPC connection without unnecessary actuator posture changes, while maintaining a small size and high durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If locking projections made of plastic engage with metal support fitting members, then the connector can achieve a simple structure, but the operational durability is reduced due to wear of the locking projections
Solution Approach 1:
The invention changes the geometric parameter of the locking portion from a conventional solid cross-section to a hollow cross-section. This parameter change allows the locking portion to maintain sufficient strength while using less material, thereby preventing wear of the locked portion without requiring a more complex structure. The hollow structure optimizes the strength-to-weight ratio and reduces material consumption at the locking portion.
2Strength
If the locking portion is made thicker to improve strength, then the strength of the locking portion is enhanced, but the size of the housing and the entire cable connector must be increased
Solution Approach 1:
The invention changes the cross-sectional geometry parameter of the locking portion from solid to hollow. This parameter change enables the locking portion to achieve optimal strength characteristics without increasing the overall thickness or housing size. The hollow structure provides efficient material distribution that maximizes strength while minimizing space occupation.
Solution Approach 2:
The invention introduces a hollow interior dimension within the locking portion structure. This dimensional change allows the locking portion to maintain external dimensions suitable for compact housing while internally optimizing the material distribution for strength. The hollow structure creates an efficient cross-sectional geometry that resists bending and tensile forces without requiring increased external thickness.

AI summary
A cable connector (1) for receiving a flexible circuit member (101) includes an insulative housing (11) with a receptacle (13) for receiving the flexible circuit member therein. A plurality of terminals are provided in terminal receiving cavities (14a, 14b). The housing includes a pair of end portions located at opposite ends of said housing with the end portions having a pair of spaced apart walls (16, 35) to provide flexibility to at least one of said walls. Each the flexible wall has a locking member (30) thereon. An actuator i(21) is mounted on the housing and moveable between first and second operative positions. The flexible circuit member being insertable when the actuator is at the first open position and being engaged by the terminals in an operative manner when the actuator is at the second closed position. The actuator includes an actuator body generally extending along the receptacle when in the second closed position and a locking portion (26) disposed on opposite ends of the actuator body. Each of the housing locking members engaging one of the locking portions disposed on the actuator when the actuator is in the second closed position.
