Outer Conductor Threading Mechanism for Accurate Coaxial Cable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronized crimping and cutting-off process of the outer conductor in coaxial cable processing leads to displacement and affects the accuracy of the threading position.
Innovation Solution
An outer conductor cutting-through device with a feeding and cutting-off mechanism, moving and threading mechanism, and gripping and supporting mechanism, which separates the cutting-off operation from the threading operation, ensuring accurate positioning and threading by first cutting off the outer conductor from the terminal strip and then threading it onto the central pin.

Engineering Contradiction Analysis
1Productivity
If crimping and cutting-off are performed synchronously, then processing efficiency is improved, but threading accuracy deteriorates due to displacement caused by cutting-off tool interference
Solution Approach 1:
The patent divides the outer conductor processing into two separate operations: cutting-off operation performed by the feeding and cutting-off mechanism, and threading operation performed by the moving and threading mechanism. This segmentation eliminates interference between cutting and threading tools, ensuring threading accuracy while maintaining processing efficiency through sequential automated operations.
Solution Approach 2:
The cutting-off operation is performed as a preliminary action before threading. The outer conductor is first cut to the correct length and positioned on the holding seat, then the threading operation is performed separately. This preliminary cutting ensures that the outer conductor is properly prepared and positioned before threading begins, eliminating displacement issues.
2Ease of manufacture
If cutting-off tool is used during crimping, then outer conductor is separated from terminal strip, but displacement occurs affecting threading position accuracy
Solution Approach 1:
The patent extracts the cutting-off function into a separate feeding and cutting-off mechanism that operates independently from the threading mechanism. The cutting-off tool is removed from the threading area, and the outer conductor is cut and positioned separately before threading begins, eliminating the harmful interference effect on threading position accuracy.
Solution Approach 2:
The holding seat serves as an intermediary component that receives the cut outer conductor and holds it in the correct position before threading. This intermediary structure ensures proper positioning and prevents displacement during the transition from cutting to threading operations.

AI summary
The present invention relates to the technical field of cable processing, and in particular to an outer conductor cutting-through device and method. The device includes: a feeding and cutting-off mechanism, including a feeding assembly for moving a terminal strip, a cutting-off assembly arranged in a terminal strip movement direction, and a holding seat arranged in a direction opposite the cutting-off assembly for holding an outer conductor; a moving and threading mechanism arranged on a side of the feeding and cutting-off mechanism, the moving and threading mechanism including a sliding seat capable of reciprocating in a direction parallel to the terminal strip movement direction, a threading driver for driving the sliding seat to move, a gripper arranged on the sliding seat, and a rotation driver connected to the gripper for driving the gripper to change in direction; and a gripping and supporting mechanism arranged on a distal end relative to a gripper movement direction, the gripping and supporting mechanism including a cable gripper for gripping a cable. In such an arrangement, the present invention achieves the separation between the cutting-off operation and the subsequent threading operation for the outer conductor, such that the cutting-off operation and the subsequent threading operation do not interfere with each other, thereby improving the accuracy in threading the outer conductor.
