Connector Fastening Structure Preventing Looseness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors tend to deteriorate and become loose over time due to repeated use, leading to unreliable connections.
Innovation Solution
A connector design featuring a main body and connecting body with a plugging pin and snap ring groove mechanism, where the plugging pin is inserted through a plugging hole and clamped within snap ring groove, providing enhanced securing and preventing looseness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional direct-depressing connectors are used, then the structure is simple, but the connection becomes loose and unreliable after repeated plugging
Solution Approach 1:
The connector is divided into distinct functional components: a plugging pin with clamping points, a plugging hole, and a snap ring groove. This segmentation allows each component to perform its specific function - the plugging pin provides insertion and clamping, the plugging hole guides alignment, and the snap ring groove provides secure retention - thereby improving connection reliability while maintaining reasonable structural complexity
Solution Approach 2:
The plugging pin is nested within the connecting body structure, with the clamping points positioned to engage with the clamp positions inside the connecting body. The snap ring groove is formed on the outer periphery of the cable connecting tube, creating a nested arrangement where the plugging pin inserts through the plugging hole and secures in the groove, providing reliable connection without excessive complexity
2Duration of action of stationary object
If conventional direct-depressing connectors are used, then the manufacturing process is simple, but the connector deteriorates over time with repeated use
Solution Approach 1:
The plugging pin is pre-formed with clamping points at its top portion, and the connecting body is pre-equipped with clamp positions and the snap ring groove. This preliminary preparation of clamping and securing features allows the connector to withstand repeated plugging operations without deterioration, extending service life while keeping manufacturing processes straightforward
Solution Approach 2:
The plugging pin automatically engages with the clamp positions and secures in the snap ring groove through its own insertion motion, without requiring additional fastening operations or complex assembly steps. This self-securing mechanism extends the connector's service life through repeated use while maintaining ease of manufacture and assembly

AI summary
The connector comprises a main body and a connecting body, the rear end of the main body and the front end of the connecting body are clamped. A plugging needle is disposed in the front shell and the cable connecting tube. A snap ring groove is disposed at the front end of the periphery of the connecting tube and is located below the plugging hole when the main body and the connecting body are connected together. A plugging hole is located on the outer periphery of the connecting body. The plugging pin is an arc plate and includes two clamping points, located on one of the ends of the top portion of the plugging pin. When the main body and the connecting body are connected, the plugging pin may be plugged through the plugging hole and stuck in the groove, and the clamping points of the plugging pin are clamped.
