SUMMARY OF THE INVENTION According to the present invention, there is provided a connector for connecting a cable core wire by laying a cable core wire on each of a plurality of contacts of a connector body and then press-fitting and tightening a connector cover. In the mounting device, a sub-unit separation mechanism having a quad feed unit having a core wire guide and a core wire pickup unit, a core wire transport unit made of a screw, and a twisting part having a core wire transferred by the core wire transport unit, which is extremely twisted. Belt and core wire separation belt,
A core wire twisting / returning mechanism including a tension belt having a tension portion, and a single core wire stretched by the core wire twisting / returning / transporting mechanism, which is positioned by the coating color of the cable core wire in the core wire transfer path. A core wire press-cutting mechanism comprising: a core wire wiring mechanism for wiring a connector body; a pusher that engages and presses a connector cover to the wired connector body; and a cutter that cuts an excess length of the core wire. A connector mounting device comprising a core wire pull-out mechanism for detaching a core wire from a wire mechanism.

[0005]

[Function] When wiring a large number of core wires to the connector body, wire the core wires to the connector body containing a plurality of contacts, and then press-fit and tighten the connector cover to connect the cable core wires. Therefore, when the cut cable is inserted into the quad supply section of the sub-unit separation mechanism and the quad supply holder is turned and positioned at the core guide, the core pick-up section advances and receives the core, and rotates and chucks. After the core wire is moved and the core wire is inserted into the screw, the core wire pick-up part rotates backward and returns, the core wire is removed, and the core wire is conveyed downward by the screw, while the core wire is twisted in the process of being conveyed by the screw. It is squeezed with a twisting belt with a take-up part, and a plurality of twists return and are separated into single-core wires, while a tension belt with a tension portion is pulled further down and a single-core wire below Is transferred to the Kurio, it goes to transport as a single-core wire to wire cloth line mechanism. In other words, the twisting part in the twisting belt that is sandwiched between the twisting plates moves and squeezes the core wire, and after taking the twist, in the process of being conveyed with a screw from above downward while completely separated by a separating mechanism, The core wire is pulled back by the tension portion of the tension belt, and the core wire is untwisted. The wire is inserted into the single core wire screw one by one, transported and pulled, and further moved downward by the screw to be transferred to the core wire wiring mechanism. Next, in the core wire wiring mechanism, with the core wire pressing plate approaching the horizontally pulled core wire and being sandwiched between the pair of support rods, the inspection unit selects the wiring position of the chucked connector body and selects the color. When the drive unit is operated and the core pressing plate is moved and positioned in the horizontal direction, the core pressing plate is moved forward, and in the process, the connector held while rotating the core sandwiched between the pair of supporting rods by 90 degrees is held. When the core wire pressing plate is retracted after inserting it into the predetermined fixed comb teeth of the main body and then rotated back, the core wires are held in the fixed comb teeth, and this operation is sequentially repeated for each core wire to complete the wiring. . Then, at the core wire pressure contact cutting section, the handlebar is pushed out by pushing the connector cover which is clamped and set by the cover setting claws with a pusher, press-fitted and fitted to the wired connector body, and then the handle is returned. Next, push the push button to protrude and fix the core wire cutter, then turn the handle again, and the core wire cutter moves forward with the pusher to cut the extra length of each wired core wire at a time, and If the handle is returned and the core wire cutter is returned to the original position, it is prepared for the next core wire pressure welding cutting. Then, when removing the connector body, the core wire can be separated from the core wire fixing comb teeth by the core wire pulling mechanism and handled as a wired connector, and the inspection unit detects the color by color for each core and detects the wiring position. The connector can be wired to the connector body, and the connection and mounting work can be performed efficiently by crimping the connector cover.
