Plug-Socket Connector Buckle Assembly for Stable Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors, particularly cable plugs, are prone to being pulled off easily due to lack of supporting structures, leading to instability and potential damage during plugging and unplugging, which affects signal transmission.
Innovation Solution
A combination of an electrical plug connector with a sliding seat, draw belt, and buckle assembly, featuring a holder base with an insulating colloid to secure the circuit board and wires, and a housing that maintains a stable connection through elastic deformation of supporting spring leaves and hook portions, preventing peeling or shaking during plug insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electrical plug connector is made small in size, then the device compactness is improved, but the connector becomes prone to peeling or shaking during plugging and unplugging
Solution Approach 1:
The connector is divided into distinct functional components: a holder base for structural support, a circuit board with contacts for electrical connection, and a housing for protection. This segmentation allows each part to be optimized independently while maintaining overall stability despite the compact size.
Solution Approach 2:
The insulating colloid is pre-formed and integrated into the holder base before final assembly. This preliminary preparation ensures that the circuit board is securely positioned and fixed in advance, preventing peeling or shaking during subsequent plugging and unplugging operations.
2Stability of the object's composition
If supporting or fixing structures are added to prevent peeling or shaking, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into single components: the insulating colloid simultaneously provides electrical insulation, mechanical fixation of the circuit board, and structural support. The housing integrates protection, positioning, and support functions. This merging reduces the number of separate parts while maintaining connection stability.
Solution Approach 2:
The holder base is formed as a composite structure integrating the insulating colloid with supporting ribs and positioning features. This composite design provides enhanced mechanical strength and stability without requiring additional separate fixing components, thus avoiding increased complexity.
3Volume of moving object
If the plug connector is made thin and small, then the device compactness is improved, but the housing, circuit board or wires become prone to peeling or shaking
Solution Approach 1:
The insulating colloid extends in multiple dimensions within the holder base, creating a three-dimensional fixed structure that anchors the circuit board and wires from various directions. This multi-dimensional fixation provides comprehensive structural support and prevents peeling or shaking despite the overall compact size of the connector.
Solution Approach 2:
The insulating colloid is pre-formed and integrated into the holder base structure before final assembly, providing beforehand cushioning and support. This pre-prepared structural reinforcement ensures that the thin and small connector maintains sufficient strength and prevents peeling or shaking of internal components during use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures accurate and stable electrical connections by preventing the housing, circuit board, and wires from separating, thus maintaining signal integrity and preventing damage to the connector.
Implementation Method 1
When the pressing surface is pressed, the supporting spring leaves are elastically deformed and the hook portions of the two support arms are shifted downward by a distance at the perforations
Implementation Method 2
When the draw belt is pulled, it pulls the sliding seat to make the elastic portions elastically deform and also link the hook portions of the two support arms to elastically deflect downward at the perforations

AI summary
A combination of electrical plug connector and matching electrical socket connector includes a plug connector, a sliding seat, a buckle assembly, a draw belt, and a socket connector. When the plug connector is docked with the socket connector, the supporting spring leaves of the buckle assembly support down to the holder base of the plug connector, so that the hook portions of the buckle assembly are hooked in the hook holes of the socket connector. When pressing the buckle assembly or pulling the draw belt, the supporting spring leaves are elastically deformed, and the hook portions are disengaged from the hook holes for separation between the plug connector and the socket connector. An insulating colloid is formed on the holder base to fix the circuit board of the plug connector, thereby firmly combining the plug connector with the holder base.
