Description

DETAILED DESCRIPTION [Overview] A device for connecting a high-speed signal transmission fracquet cable to a connector, in which a locator is sandwiched by a locator support and an insulator is locked by an insulator support that moves up and down. When the insulator support portion is lowered toward the locator support portion to mount the locator on the insulator, the locator holding means provided in the insulator locking means is configured to slide down from the locator, thereby insulating the locator. This is an easy task to insert into the body.

[Industrial application field]

The present invention relates to a crimping device for connecting a fracquet cable to a connector.

A high-speed signal transmission fracquet cable is a fracquet cable in which a plurality of cables each having one ground wire on each side of one signal line are connected in parallel, and generally between the signal lines with a pitch of 1.27 mm. Two ground lines are provided.
