Connector structure for signal line and crimping tool thereof

A crimping tool of a connector structure for a signal line comprises:

• a first and a second clippers axially connected together by using a pivotal member;
• a press mechanism defined between the first and the second clippers and including a holder installed onto the first clipper, and including a positioning recess to receive a connector, and including a coupling plate connected with the second clipper in response to a guide member of a connector, such that as the first and the second clippers are pressed, the coupling plate is actuated to press the guide member of the connector;
• a cutting mechanism defined between the first and the second clippers and including a stopping member to contact with the front end of the body so that the cores of the signal line are arranged on the stopping member after extending out of the front end of the body, and the second clipper being in response to a blade above the stopping member, hence as pressing the first and the second clippers, the blade and the stopping member cut the extended cores evenly.
