Cable Insertion Device and Connector Manufacturing Device

A cable insertion device, comprising:

• a first block having a top surface and a bottom surface opposite the top surface in a vertical direction, and a front side and a rear side opposite the front side in a first horizontal direction, a row of slots is formed on the top surface of the first block;
• a second block assembled onto the top surface of the first block, a bottom surface of the second block is against the top surface of the first block, a row of upper semicircular holes corresponding to the row of slots is formed on the bottom surface of the second block;
• a third block assembled onto the front side of the first block, a row of lower semicircular holes corresponding to the row of slots is formed on a top surface of the third block, one of the upper semicircular holes and one of the lower semicircular holes are combined into a guide hole for guiding a cable into a cable hole of a connector housing;
• and
• a locking component clamped between the first block and the third block, the locking component has a row of elastic cantilevers corresponding to the row of slots, each of the elastic cantilevers extends into one of the slots and rests against the cable inserted into the cable hole to prevent the cable from being pulled out of the cable hole of the connector housing.
