Abstract: A crimping device for a cable terminal has a crimping base, a driving assembly, a die mount, and a connector. The connector connects the crimping base and the die mount. The die mount is driven by the driving assembly to linearly move back and forth. A mutual pulling force is formed between the crimping base and the die mount. When compressing, deformation of the crimping base can be effectively reduced, and a service life of the crimping base can be extended. Moreover, the die mount does not move laterally, thereby avoiding the situation that the driving assembly would be failed after long-term used.
