Electrical Connector Tool-Free Installation via Bump Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of electrical connectors on electronic devices is complicated and time-consuming due to the need for small components like pins and screws, which are easy to lose and require tools, affecting productivity.
Innovation Solution
An electrical connector design featuring an insulation body, seat, and positioning plug with a sliding block and rib mechanism that allows rapid installation without tools, using a tunnel, slit, and bumps to secure the connector in place, eliminating the need for external fixing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pins or screws are used to fix the electrical connector on the back plate, then the connector can be securely fixed, but the installation becomes complicated and time-consuming requiring tools and multiple small components
Solution Approach 1:
The patent integrates the fixing function directly into the connector body by incorporating a positioning plug with bumps that engage with corresponding structures on the back plate. This merging of the connector and fixing mechanisms eliminates the need for separate pins or screws, allowing secure attachment while simplifying the installation process to a single integrated component.
Solution Approach 2:
The positioning plug is designed to be manually inserted and pushed into place without requiring any external tools. The sliding block mechanism allows the plug to move along the insertion direction and automatically engage with the back plate structure, enabling tool-free installation while maintaining reliable fixation.
2Reliability
If pins or screws are used for fixing, then secure connection is achieved, but small components are easy to fall and lose
Solution Approach 1:
The fixing structure is merged into the connector body as an integrated positioning plug. The bumps on the positioning plug engage directly with corresponding features on the back plate, eliminating separate small components like pins or screws that could be lost. This integration ensures that the fixing mechanism remains with the connector throughout the assembly process.
3Reliability
If traditional fixing methods with separate components are used, then connection is achieved, but installation requires tools and correct specifications
Solution Approach 1:
The positioning plug is designed for tool-free installation by manual insertion. The sliding block mechanism allows the plug to move smoothly along the insertion direction and engage automatically with the back plate structure. This self-service design eliminates the need for tools and reduces requirements for specific component specifications, making installation more accessible and easier to perform.

AI summary
An electrical connector includes an insulation body, a seat, and a positioning plug. The seat is disposed on an outer peripheral surface of the insulation body. The seat includes a tunnel defined through the seat to form an inlet and an outlet. The outlet and a front surface of the insulation body face the same side. The seat further includes a slit and one or more first bumps disposed on an inner wall of the slit. The positioning plug includes a sliding block and rib. The sliding block movably disposed in the tunnel via the inlet with the rib movably disposed in the slit. The positioning plug further includes a second bump disposed on a lateral side of the rib facing the first bump. When the sliding block moves to an installation position, the first bump stops the second bump to fix the sliding block at the installation position.
