Description

Technical Field

[0001] The utility model relates to the technical field related to terminal production and processing, and in particular to a semi-automatic terminal shell positioning and twisting jig. Background Art

[0002] During the production and processing of electrical wires, data cables and optical fiber cables, it is necessary to use a shell twisting jig to install the terminal on the outer end of the wiring to facilitate the installation, connection and protection of the wiring. However, the existing shell twisting jig has a relatively simple positioning method when installing the terminal shell, and mainly adopts a more traditional card slot structure to position the terminal and the shell. Obviously, this positioning method cannot guarantee its positioning effect on the shell and the terminal. When the outer diameter of the terminal and the shell changes, the jig will have difficulty in positioning the shell and the terminal. For this reason, we propose a semi-automatic terminal shell positioning and shell twisting jig. Utility Model Content
