Coaxial Connector Pin Trim Markings for Consistent RF Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate trimming of coaxial connector center pins is challenging due to the lack of precise markings, leading to inconsistent radio frequency performance, especially at higher frequencies, as users rely on adapters' width for trimming, which can result in incorrect pin lengths and performance issues.
Innovation Solution
The introduction of markings on the connector pin, such as laser-etched trim marks, indicating specific cut locations to ensure consistent radio frequency performance when connected to adapters, eliminating the need for users to rely on adapters' width for trimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If trim length marks are included on the adapter body, then users can identify trim locations, but the trimming process becomes less accurate because users must hold the connector pin up to the adapter and mark with their fingers, which may move during cutting
Solution Approach 1:
Instead of placing trim marks on the adapter body and requiring users to reference them externally, the patent inverts the approach by placing the trim marks directly on the connector pin itself. This allows the pin to serve as its own measurement reference, eliminating the need to hold the pin against the adapter and preventing finger movement during cutting. The pin's own structure provides the trimming reference, resolving the accuracy problem.
2Device complexity
If no trim markings are provided on the connector pin, then the connector structure remains simple, but users cannot accurately determine the correct cut location, leading to inconsistent RF performance
Solution Approach 1:
The patent applies local quality by adding trim markings only to specific locations on the connector pin where they are most needed - on the pin itself rather than on the entire connector assembly. The markings are placed at specific positions (such as at the end of the pin or at predetermined distances from the pin tip) to provide localized trimming guidance. This minimal addition of markings maintains overall structural simplicity while providing the necessary information for accurate trimming and consistent RF performance.
3Ease of operation
If the pin is trimmed too short without proper markings, then the connector cannot be installed, but users have no visual guidance to prevent this, resulting in waste of the entire connector
Solution Approach 1:
The patent applies preliminary action by providing trim markings on the pin before the trimming operation begins. These markings indicate the correct cut location in advance, allowing users to trim the pin to the proper length on the first attempt. By having the reference marks预先 prepared on the pin itself, users can accurately determine where to cut without risking trimming the pin too short and wasting the entire connector.

AI summary
A cable connector structurally configured to facilitate accurate trimming of a connector conductor of the connector to provide consistent radio frequency performance of the connector, including: a connector portion structurally configured to connect to an adapter; and a connector conductor structurally configured to extend from the connector portion. The connector conductor comprises a marking; the connector conductor is structurally configured to electrically connect to a conductor of a cable; the connector conductor is structurally configured to be received by the adapter; and the marking is structurally configured to indicate a cut location of the connector conductor so as to provide consistent radio frequency performance of the cable connector when connected to the adapter.
