Description

Technical Field

[0001] The utility model belongs to the technical field of cable processing, in particular to a clamping and positioning structure for cable crimping. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. During the processing of cables, the terminals on the raised parts of the mother tape need to be crimped to the top of the wire. Now, during the crimping process, the operator puts the wire on the crimping table, controls the pressure head to press down through the telescopic cylinder, and completes the crimping of one wire. The mother tape is manually pulled forward to position the terminals on the mother tape and the crimping interface on the crimping table, and then the next wire is replaced and the cylinder is started to press down. The crimping often deviates due to manual positioning, causing the processed cable to be unusable, wasting resources and increasing costs. After searching, the patent with application number 202320639714.1 discloses a clamping and positioning structure for cable crimping, which is characterized by including a base, a support rod, a cylinder, a lower pressure rod, a pressure head, a crimping table, a guide plate, and a positioning part. The base is fixedly connected to the crimping table, the rear side of the crimping table is fixedly connected to the support rod, the upper end of the support rod is fixedly installed with a cylinder, the push rod end of the cylinder is connected to the lower pressure rod, one side of the lower pressure rod is connected to the positioning part, the bottom end of the lower pressure rod is connected to the pressure head, and one end of the crimping table is connected to the guide plate.

[0003] However, during actual use, the applicant found that when crimping the cable, the lower pressure rod moves downward, driving the rocker and the push block to rotate clockwise, and when the lower pressure rod moves upward to reset, the raised terminal on the mother tape is pushed forward by the reset rotation of the rocker and the push block. In the process of the push block pushing the mother tape forward, since the rocker and the push block are pendulum-like reset movements and the resistance encountered by the mother tape during each movement is not exactly the same, the distance the mother tape is pushed forward each time will be not exactly the same, which makes the cable compression positioning not accurate enough. In view of this, we propose a clamping and positioning structure for cable crimping. Utility Model Content
