Terminal Supporting Device Lock Member Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal supporting devices for cables, such as control cables, face complications in preventing looseness of the cylindrical nut member during transportation and attachment to a bracket, requiring either complex structures or strong biasing forces that lead to difficult temporary fixation and potential detachment of the stopper.
Innovation Solution
A terminal supporting device with a tubular main body, a socket, a biasing member, and a lock member that includes a lock body with a fitting projection and sliding arm portions to prevent oscillation and ensure easy attachment to a bracket, allowing for quick and simple cable terminal fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the biasing force of the coil spring is strengthened to prevent loosening of the cylindrical nut member, then the loosening prevention is improved, but the temporary fixation becomes difficult and the stopper may detach during transportation
Solution Approach 1:
The invention divides the stopper into two separate functional parts: a lock member with locking protrusions for preventing loosening, and a stopper body for temporary fixation. This segmentation allows each part to perform its specific function independently - the lock member provides reliable loosening prevention through engagement with the socket member, while the stopper body provides easy temporary fixation without requiring strong biasing force.
Solution Approach 2:
The invention introduces a lock member as an intermediary component between the socket member and the stopper body. The lock member with its locking protrusions mediates the interaction between these components, providing the necessary locking function while allowing the stopper body to perform temporary fixation with reduced biasing force, thus resolving the contradiction between reliability and ease of operation.
2Device complexity
If the structure for preventing loosening is simplified by strengthening the biasing force, then the device complexity is reduced, but the stopper may detach during transportation due to oscillation
Solution Approach 1:
By segmenting the stopper into a lock member and stopper body, the invention maintains simple device complexity while improving stopper attachment reliability. The lock member with locking protrusions provides secure engagement that prevents detachment during transportation, while the overall structure remains simple and easy to understand.
Solution Approach 2:
The lock member is designed to be movable, allowing it to dynamically respond to oscillations during transportation. The locking protrusions can flexibly engage and disengage from the socket member, maintaining reliable attachment while accommodating dynamic movements, thus resolving the contradiction between device complexity and reliability.
3Stability of the object's composition
If a lock member is added to keep the distance between socket and stopper, then the stability is improved, but the device complexity increases
Solution Approach 1:
The invention merges the locking function and the distance-maintaining function into a single integrated lock member. The locking protrusions on the lock member simultaneously provide locking action and maintain the distance between the socket and stopper, thereby improving stability without significantly increasing device complexity.
Solution Approach 2:
The lock member is designed as a multi-functional component that performs multiple functions: it provides locking to prevent loosening, maintains the distance between socket and stopper, and works with the stopper body for temporary fixation. This universality allows the device to achieve improved stability without adding separate dedicated components for each function.

Function Achieved in This Case
The device enables quick and easy fixing of cable terminals with a simple configuration, reducing the risk of stopper detachment during transportation and eliminating the need for strong biasing forces, thereby improving workability and stability.
Implementation Method 1
a biasing member (30) having a biasing force which gives the socket (20) a torque in the direction approaching the stopper (40)
Implementation Method 2
the lock body (51) has a fitting projection (54), and the stopper (40) has a fitting depression (42a) which fits with the fitting projection of the lock body
Implementation Method 3
the frictional force between the cylindrical nut member 103 and the stopper 104 is strong due to the bias in the state where the attachment of the terminal supporting device 100 to the bracket 110 is not performed yet
