Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit testing connectors require complex, time-consuming assembly processes and are prone to wear and displacement due to positioning rings, affecting center alignment and potentially damaging the electronic product being tested.
Innovation Solution
A connector design featuring a mounting seat, extending seat, and central pin modules with integrated positioning rings and resilient elements allows for one-step locking onto a fixing jig, maintaining structural integrity and enabling automatic center correction in multiple directions, reducing wear and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the connector is locked onto the fixing jig using conventional multi-step assembly, then the connection can be established, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple assembly operations into a single integrated locking mechanism. The connector assembly includes a base portion with positioning rings and a fastening portion that can be locked onto the fixing jig in one operation, eliminating the need for separate positioning and fastening steps required by conventional connectors.
Solution Approach 2:
The connector is divided into distinct functional modules: a base portion containing positioning rings for automatic center alignment, a fastening portion for locking, and a fixing panel with test pins. This segmentation allows each module to perform its function independently while enabling one-step assembly of the complete unit.
2Ease of operation
If positioning rings are mounted on screws that rotate during assembly, then the connector can be fastened, but the positioning rings wear and displace, affecting center alignment
Solution Approach 1:
The positioning rings are extracted from the rotating screw components and mounted instead on the non-rotating base portion. This separation ensures that the positioning rings remain stationary and maintain their center alignment function without suffering from wear or displacement caused by rotational motion during fastening operations.
Solution Approach 2:
The base portion serves as an intermediary structure that holds the positioning rings in fixed positions. This mediator component transfers the alignment function from the rotating screws to a stable, non-rotating platform, ensuring reliable center alignment while allowing the screws to rotate freely for fastening.
3Manufacturing precision
If the connector requires precise locking torque control, then proper fastening can be achieved, but the operation becomes complex and attention-intensive
Solution Approach 1:
The fastening portion is designed with self-aligning features including positioning rings and complementary positioning structures on the fixing jig. These features guide the connector into the correct position automatically, eliminating the need for operators to control locking torque precisely. The structure itself performs the alignment function that would otherwise require skilled operation.
4Stability of the object's composition
If the stationary base is rigidly fixed, then structural stability is achieved, but automatic center correction capability is lost
Solution Approach 1:
The connector incorporates controlled flexibility through resilient elements and positioning rings that allow limited movement. The base portion can tilt and adjust its position within certain limits to achieve automatic center alignment with the fixing jig, while the fastening portion provides rigid fixation once aligned. This dynamic adjustment capability coexists with structural stability during operation.

AI summary
A connector for circuit testing includes a mounting seat, an extending seat, a fixing panel, and at least one central pin module. A rear end portion of the extending seat is mounted in a connecting hole of the mounting seat. At least one positioning ring is mounted around the rear end portion and is held between the extending seat and an inner sidewall that is defined around the connecting hole. Each of the at least one central pin module has a rear end held on the fixing panel and is mounted in the extending seat. The fixing panel is locked to a rear side surface of the mounting seat with multiple first fasteners. A whole of the connector can be locked to a fixing jig at once, which is simple and fast to assemble, without causing the at least one positioning ring to wear out.
