Cable End Connector With Limiting Notch For Secondary Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable end connectors have a guiding member that only performs preliminary positioning, leading to increased size without effective limiting, resulting in a larger volume.
Innovation Solution
The cable end connector incorporates a guiding member with a limiting notch and two positioning bumps on the plugging surface, allowing for secondary guidance positioning and maintaining the surface area within the plugging surface's bounds, preventing excessive volume increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the guiding member is provided on the periphery of the connector body for preliminary positioning, then the connecting position between board end connector and cable end connector can be preliminarily positioned, but the size of the cable end connector increases
Solution Approach 1:
The patent combines the guiding member and limiting member into a single integrated component. The guiding member includes both a guiding portion for preliminary positioning and a limiting portion for final position limitation, merging two separate functions into one structure. This integration allows the connector to achieve both preliminary and final positioning without requiring separate components, thereby preventing volume increase while maintaining positioning precision.
Solution Approach 2:
The guiding member is designed to perform multiple functions: it provides preliminary positioning through its guiding portion and simultaneously provides final position limitation through its limiting portion. This multi-functional design eliminates the need for separate limiting members, resolving the contradiction between achieving precise positioning and maintaining compact connector size.
2Device complexity
If the guiding member only performs preliminary positioning without limiting function, then the structure is simple, but the connecting position cannot be effectively limited
Solution Approach 1:
The patent integrates the limiting function into the existing guiding member by adding a limiting portion to the guiding member. This combination allows the single component to perform both preliminary positioning and final position limitation, improving positioning precision without significantly increasing structural complexity.
3Reliability
If the surface area of mating exceeds the plugging surface area, then the connection can be more secure, but the volume of the cable end connector increases excessively
Solution Approach 1:
The patent applies local quality by concentrating the positioning and limiting functions at specific locations (the guiding member with its guiding portion and limiting portion) rather than expanding the overall mating surface area. This allows secure connection through localized precise positioning without increasing the overall connector volume.

AI summary
A cable end connector comprising a plugging member, a plurality of cables, an insulating body, a latch component, a guiding member, and two positioning bumps. The insulating body comprises a plugging surface, a first surface, and a connecting surface. The plugging member protrudes from the plugging surface. One ends of the plurality of cables protrude from the connecting surface. The first surface comprises a latch accommodating groove accommodating the latch component. The guiding member and the two positioning bumps are disposed on the plugging surface and is disposed on a side edge of the plugging surface. The guiding member comprises a limiting notch disposed on one side of the guiding member away from the plugging surface. The preliminary positioning and the secondary guidance positioning can be achieved by providing a limiting notch on the guiding member, which performs the function of limiting after being connected to the board end connector.
