Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial cable connectors face challenges in miniaturization, leading to insufficient engagement strength and ease of detachment due to low contact height and area, and manual assembly difficulties exacerbated by small connector sizes, which complicates automation and increases production costs.
Innovation Solution
A coaxial cable connector assembly utilizing a lateral insertion method with a receptor connector featuring a lateral insertion opening, a cable end connector with clamps for secure crimping, and engagement structures to enhance electrical connections and prevent detachment, along with a guiding structure for easier alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the connector size is scaled down to meet miniaturization requirements, then the height of the connector is reduced, but the contact height and area become insufficient leading to weak engagement strength
Solution Approach 1:
The patent transitions from a top-down engagement method to a lateral insertion method. The cable end connector is inserted horizontally into the receptor connector from the side rather than from above, changing the engagement dimension. This allows the connector to achieve sufficient engagement strength through lateral contact surfaces while maintaining reduced overall height, effectively resolving the contradiction between miniaturization and engagement strength.
Solution Approach 2:
The connector structure is divided into distinct functional components: a cable end connector with engagement protrusions and a receptor connector with corresponding engagement grooves. The engagement interface is segmented into multiple contact points including lateral engagement surfaces and bottom contact surfaces, distributing the engagement force across multiple areas to enhance overall engagement strength despite reduced connector height.
2Volume of moving object
If the connector size is reduced, then the connector becomes more compact, but manual assembly becomes difficult due to blocked line of sight and improper alignment
Solution Approach 1:
By changing from vertical top-down assembly to horizontal lateral insertion, the patent improves operator visibility and alignment capability. The lateral approach allows operators to clearly see the engagement interface from the side without fingers blocking the line of sight, making manual assembly of miniaturized connectors feasible and accurate.
Solution Approach 2:
The patent introduces guiding structures including engagement grooves and protrusions that act as mechanical intermediaries to align the cable end connector with the receptor connector. These guiding features automatically position the connectors correctly during lateral insertion, eliminating the alignment difficulties faced in manual top-down assembly of small connectors.
3Ease of manufacture
If top-down engagement method is used, then the connector can be assembled, but the engagement strength is insufficient and connectors can be easily detached under external impact
Solution Approach 1:
The patent replaces the vertical top-down engagement with horizontal lateral insertion. This dimensional change creates broader lateral engagement surfaces and multiple contact points that distribute mechanical stress, preventing easy detachment under external impact forces while maintaining manufacturing simplicity through the straightforward insertion motion.
Solution Approach 2:
The connector design incorporates pre-formed engagement protrusions and grooves that are built into the connector structures during manufacturing. These preliminary engagement features are positioned to automatically engage when lateral insertion occurs, ensuring reliable connection before the connector is subjected to any external forces during use.

AI summary
A coaxial cable connector assembly and a receptor connector are provided. The coaxial cable connector assembly is composed at least of one cable end connector and the receptor connector. The receptor connector is formed of an insertion space with a lateral insertion opening to allow one portion of the cable end connector to be inserted into the insertion space through the lateral insertion opening such that the cable end connector and the receptor connector are in electrical connection. The cable end connector will be constrained such that it cannot be detached from the receptor connector in the direction other than the lateral insertion opening.
