Solution Overview
Problem
Current power sockets and patch boards lack effective safety measures to prevent accidental electric shocks, particularly from curious children inserting conductive objects into jacks.
Innovation Solution
A supported slide safety member is integrated into the upper cover of sockets and patch boards, featuring inclined surfaces, a slide block with a supporting shaft, and elastic components to prevent conductive objects from reaching power contacts during non-normal use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sockets and patch boards are used without safety members, then the device structure is simple and easy to manufacture, but users (especially children) are at risk of electric shock from inserting conductive objects
Solution Approach 1:
The patent introduces a safety member as an intermediary component between the conductive object and the power contact. This safety member includes a blocking portion that physically intercepts conductive objects, preventing them from reaching the power contact. The blocking portion acts as a mediator that stops harmful conductive objects while allowing normal plug insertion, thus resolving the contradiction between safety and structural simplicity.
Solution Approach 2:
The safety member is segmented into distinct functional portions: a blocking portion with inclined surfaces to intercept conductive objects, and a guiding portion to guide normal plugs. This segmentation allows each portion to perform its specific function efficiently while keeping the overall structure relatively simple and manufacturable.
2Object-affected harmful factors
If a safety member with blocking portion is added to prevent conductive objects, then safety against electric shock is improved, but the device structure becomes more complex
Solution Approach 1:
The safety member merges multiple functions into a single integrated component: the blocking function (blocking portion), the guiding function (guiding portion), and the elastic actuation (elastic component). By combining these functions into one safety member rather than separate components, the structure remains relatively simple while achieving comprehensive protection against conductive objects.
Solution Approach 2:
The safety member incorporates an elastic component that enables dynamic movement of the blocking portion. The blocking portion can move between a blocking position (when no plug is inserted) and a retracted position (when a plug is inserted). This dynamic characteristic allows the safety member to adapt to different situations automatically, providing protection when needed and allowing normal operation when appropriate, without requiring complex control mechanisms.
3Object-affected harmful factors
If inclined surfaces are added to the blocking portion to guide conductive objects, then the effectiveness of preventing electric shock is improved, but manufacturing complexity increases
Solution Approach 1:
The inclined surfaces on the blocking portion change the geometric parameters of the safety member to achieve effective deflection of conductive objects. By optimizing the inclination angles and surface shapes, the design achieves effective guidance and deflection of conductive objects while keeping the manufacturing process relatively simple. The inclined surfaces are integrated into the blocking portion as a continuous feature rather than separate components, facilitating easier manufacturing.

Function Achieved in This Case
Ensures safety by preventing conductive objects from passing through the slide block and cover plate windows, thereby preventing electric shocks.
Implementation Method 1
An elastic component is connected between the slide block and the upper cover, and an action direction of an elastic force of the elastic component is in the direction of the head end of the slide block.

AI summary
A supported slide safety member. A slide block disposed on the inner side of an upper cover of a socket, includes two inclined surfaces in the same direction disposed on the outer side of the slide block with a slide block window respectively disposed on a lower side of each inclined surface, and a protruding supporting shaft disposed on the inner side of the slide block. A cover plate with two cover windows is disposed on the inner side of the slide block, and the outer side of the cover plate is in contact with the supporting shaft. An elastic component is connected between the slide block and the upper cover. A stop surface is disposed on both the inner side and the outer side of a tail end of the slide block, stopped by and upper stop rib and a lower stop rib.
