Pull-Type Tripping Device for Electrical Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional button-type tripping devices for electrical connectors are inconvenient in tight spaces due to the increasing proximity of components on motherboards, making it difficult to press the tripping button and release the snap hook buckles.
Innovation Solution
A pull-type tripping device featuring a snap hook unit with a fixed and flexible arm, and a pull belt that allows the snap hooks to be released by pulling the belt, even in limited spaces, facilitating the unbuckling of electrical connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button type tripping device is used, then the snap hook buckles can be released, but the operation becomes difficult in tight spaces where components are closely spaced
Solution Approach 1:
The tripping mechanism transitions from a depth-based operation (pressing a button deep inside the connector) to a surface-based operation (pulling a belt from the outer surface). This dimensional shift allows the tripping action to be performed from the outside of the connector, making it accessible in tight spaces where fingers cannot reach deep inside.
Solution Approach 2:
The pull belt serves as an intermediary element that transmits the user's pulling force from the outer surface of the connector to the snap hook mechanism inside. This intermediary allows the user to operate the tripping mechanism without directly accessing the internal button, solving the accessibility problem in confined spaces.
2Productivity
If components on the motherboard are placed closer together, then the device density increases, but the tripping button becomes inaccessible for pressing
Solution Approach 1:
The solution moves the operational interface from the internal depth dimension to the external surface dimension. The pull belt is routed through the housing and accessible from the outside, allowing tripping operations to be performed without requiring finger access to the internal space, thus maintaining operability even when components are densely packed.
Solution Approach 2:
The critical tripping function is extracted from the deep internal location and brought to the outer surface through the pull belt mechanism. This extraction allows the essential operation to be performed from an accessible location while the actual snap hook release still occurs at the original internal position.

AI summary
A pull-type tripping device for an electrical connector has a housing unit and a connector body unit. The connector body unit is disposed inside the housing unit, the connector body unit has a board body and a frame body vertically coupled to each other, a plurality of contact terminals are formed inside the frame body, and each upper portion of two sides of the frame body is formed a hook opening thereon. The pull-type tripping device includes a snap hook unit and a pull belt. The snap hook unit includes a fix arm, a flexible arm, and two snap hook arms. Each of the snap hook arms is disposed inside the frame body, and each of the two snap hook arms is removably buckled at the hook opening.
