Spring Lock Connector Interface for Cross-Thread-Free Cable Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interface devices for securing and locking electrical connectors in a common frame face challenges with cross-threading and contamination, particularly when using multi-start Acme lead screws, which require lubrication and have limited compatibility with larger wire bundles.
Innovation Solution
A test adapter assembly with a collar support plate angled at 40-50° relative to the frame, a locking mechanism featuring a spring lock nut and multi-start Acme lead screw for secure engagement, and a cover to prevent contamination, allowing for larger wire bundles and eliminating cross-threading risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-start Acme lead screw is used for engagement, then consistent low torque engagement is achieved, but cross-threading risk and lubrication contamination occur
Solution Approach 1:
The spring-loaded collar applies preliminary radial force to the lead screw threads before engagement, pre-aligning the multi-start Acme threads and eliminating cross-threading risk while maintaining consistent low torque operation throughout the engagement process
2Adaptability or versatility
If standard collar angle is used, then simple structure is maintained, but larger wire bundles cannot be accommodated
Solution Approach 1:
The collar support plate is angled at 45 degrees relative to the frame face, changing the geometric parameter to create a wider opening angle in the collar. This allows larger wire bundles to pass through while the spring mechanism maintains adequate clamping force on the cables
3Ease of operation
If open collar design is used, then easy cable access is achieved, but contamination of electrical components occurs
Solution Approach 1:
The collar assembly is segmented with a removable cover that can be opened during cable installation and closed during operation. The spring-loaded collar remains accessible for cable management while the closed cover protects electrical components from contamination when not in use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, low-torque engagement system that prevents cross-threading and contamination, accommodating larger wire bundles while ensuring consistent and reliable connections between electrical connectors.
Implementation Method 1
the use of a multi start Acme lead screw provides a, consistent, low torque means of engagement
Implementation Method 2
Because the present invention allows the ACME threads to be 'meshed' at all times, it also eliminates the possibly of cross-threading
Implementation Method 3
the lube is contained in a sealed environment. This eliminates the risk of contamination to electrical components

AI summary
A test adapter assembly for an interface. The test adapter assembly has a test adapter frame having a first pair of opposing sides, a second pair of opposing sides and an engagement mechanism support member, the second pair of opposing sides being shorter than the first pair of opposing side, the first and second pairs of opposing sides forming a test adapter face; and a collar support member, the collar support member having plate portion mounted to one of the second pair of opposing sides of the test adapter frame and a collar mounting portion extending from the plate portion at an angle of 40-50° relative to the face of the test adapter frame.
