Cable Connector Assembly Locking Structure for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies lack a secure method to stabilize the housing and metal shell, leading to potential instability during high-speed signal transmission.
Innovation Solution
A cable connector assembly with a locking structure that includes a housing with a first and second base, conductive pads, a pulling mechanism, and a metal shell, where locking pieces are inserted into grooves on the second base and bent to secure the first base, and the metal shell is secured using bolts and U-shaped hooks to enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and bolts are used to assemble the first base, second base, and metal shell, then the assembly is simple to manufacture, but the stabilization of the cable connector assembly is insufficient
Solution Approach 1:
The housing is divided into a first base and a second base that are assembled together to form a receiving room. This segmentation allows for modular assembly while maintaining structural integrity through the locking mechanism.
Solution Approach 2:
Locking pieces are pre-installed on the first base and extend into through grooves on the second base before final assembly. This preliminary positioning ensures proper alignment and stabilization without requiring complex assembly procedures.
Solution Approach 3:
Locking pieces serve as intermediary elements between the first base and second base, providing a mechanical interlock that enhances stabilization. These locking pieces engage with the through grooves to prevent separation while maintaining assembly simplicity.
2Reliability
If long bolts are used to run through the first base, second base, and metal shell, then the assembly is secured, but the device complexity increases
Solution Approach 1:
The locking function is extracted from the bolt assembly and implemented through dedicated locking pieces that engage with through grooves. This separation of functions allows for simpler fastening while maintaining assembly security.
Solution Approach 2:
Locking pieces act as intermediary components that provide the securing function without requiring long bolts to traverse all components. The locking pieces engage locally at critical interfaces to prevent separation.

AI summary
A cable connector assembly includes a housing including a first base and a second base coupled with the first base, at least a circuit board received in the housing and defining two rows of conductive pads located at two opposite sides thereof, at least a cable including a plurality of conductors electrically connecting with one row of the conductive pads of the circuit board, a pulling mechanism movably fixed to an outside face of the housing and separating the cable connector assembly from a complementary cable connector, and a metal shell partially shielding the pulling mechanism. The second base defines through grooves. The first base includes locking pieces inserted into the through grooves with free ends extending out of the through grooves from the outside face and bended to abut against the outside face of the housing.
