Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable pressure welding device for forming slits in recesses between conductors of a flat multi-conductor cable and inserting and press-welding the cable into a pressure welding connector.

Normally, when a flat multi-conductor cable 1, which is made by arranging a large number of conductors 11 in parallel and integrally molded with an insulating material as shown in FIG. I needed to. Here, in conventional cable pressure welding equipment, it was common to use a mechanical press, so if a die set for slitting and a die set for connector pressure welding are incorporated into this mechanical press,
These die sets occupy a limited space, and the space for attaching and detaching the flat multiconductor cable 1 becomes narrow, resulting in a disadvantage that work efficiency is significantly reduced. Therefore, in general, the slit processing station and the connector pressure welding station are separated, and the flat multiconductor cable 1 with the slits 13 formed in the slit processing station is transferred to the connector pressure welding station using a mechanical transfer mechanism. There, they were inserted into pressure-welding connectors and pressure-welded. Therefore, due to the total error caused by the accumulation of tolerances of each component of the mechanical transfer mechanism, the insulation-coated conductor portion 1 of the flat multi-conductor cable 1 is attached to the insulation displacement contact portion of the insulation displacement connector.
4 was not fixed, which caused poor pressure contact.

The present invention has been made to eliminate these drawbacks, and after a flat multi-conductor cable is placed and fixed on a single station, slitting and connector pressure welding are sequentially performed at the same station. This method improves work efficiency, shortens processing time, prevents the occurrence of pressure welding defects, and improves pressure welding quality.The gist of this is that the fixed die member and intermediate member are The fixed die member has a cable mounting base on its upper surface having a groove corresponding to the conductor pitch of the flat multi-conductor cable, a groove on its upper surface that is connected to the groove of the cable mounting base, and a side surface thereof. It is equipped with a movable table that has comb-like protrusions corresponding to the groove and is slidably attached in the direction of the groove, and a connector holder that receives the pressure-welding connector supplied from the connector supply means and applies pressure when the cable is pressure-welded. The intermediate member has a cable grip holder for gripping the flat multi-conductor cable placed on the cable mounting table, and a comb tooth-like protrusion connected to the comb tooth-like protrusion of the movable table. It is equipped with a cable holding holder that holds down a flat multi-conductor cable, and a punch holder that has a comb-toothed blade that engages the comb-toothed protrusion tube of this cable holding holder, each of which can be freely slid vertically and is movable. A slit was formed by lowering the punch holder into the recess between the conductors at the tip of the flat multi-conductor cable, which was held down by the table and cable holding holder so that the convex part of the conductor fit into the groove. The tip of the flat multi-conductor cable is held down by a cable holding holder, the pressure welding connector received in the connector holder is pressed, and the conductor of the flat multi-conductor cable is inserted into the pressure contact portion of the pressure welding connector and pressure welded. Located in cable pressure welding equipment. A detailed explanation will be given below with reference to the drawings.

This is a connector holder that applies pressure to the received press-connecting connector 4. The fixed die member 2 has a clip 25 for temporarily holding the flat multi-conductor cable placed outside these, and a stopper 2 for positioning the flat multi-conductor cable when it is placed.
6 and its drive mechanism 261.

Further, 3 is an intermediate member, 31 is a guide attached to this intermediate member 3, and 32 is a guide having a V groove opposite to the V groove 211 of the cable mounting table 21 on the lower surface thereof.
A cable grip holder is provided with a groove 321 and holds the flat multi-conductor cable placed on the cable mounting table 21, and 33 is a cable that is held against the flat multi-conductor cable on the movable table 22 during slit processing and connector pressure bonding. The presser foot holder has a V groove 331 connected to the V groove 321 on its lower surface.
Further, the end side surface thereof corresponds to the V-groove 331 and the comb-like protrusion 222 of the movable table 22.
The lower surface of this comb-like protrusion 332 has the shape of a cable receiving recess at the top of the pressure welding connector, and the conductor portion 14 of the flat multi-conductor cable 1 is welded during pressure welding. It is designed so that it can be guided deep into the pressure contact of the connector. Further, numeral 34 denotes a punch holder having comb-tooth-like blades 341 arranged to mesh between the comb-tooth-like protrusions 332 of the cable holding holder 33 . These cable grip holder 32, cable press holder 33 and punch holder 34
is housed in the guide 31, and its protrusion 311
They are held so as to be able to slide vertically without wobbling, and are independently controlled to rise and fall by link mechanisms 322, 333, and 342 using, for example, air cylinders as driving sources. The intermediate member 3 equipped with these various holders has a toggle mechanism 35
It is installed so that it can be raised and lowered freely.

Next, the pressure welding process of the pressure welding connector by the cable pressure welding device of the present invention will be explained using FIG.

First, the movable table 22 is moved to a position where it contacts the stopper 26 placed in a fixed position, and the flat multiconductor cable 1 is placed thereon so that its tip is in contact with the stopper 26, and then the cable 22 is held in place by the clip 25. Then, temporarily stop it on the cable mounting stand 21. Then,
After confirming that each conductor convex portion 15 of the flat multiconductor cable 1 is fitted into the V grooves 211 and 221 of the cable mounting table 21 and the movable table 22, the apparatus is started.

As a result, the intermediate member 3 first descends to a predetermined position, and at the same time the stopper 26 retreats. When the intermediate member 3 stops lowering, the cable grip holder 32 lowers and grips the flat multi-conductor cable 1 between it and the cable mounting table 21. In this way, the flat multiconductor cable 1 is accurately positioned and held by the V-grooves 211 and 321, and some bends in the cable are corrected. This grip on the flat multi-conductor cable 1 is not released until the pressure welding operation of the pressure welding connector is completed. Next, the cable holding holder 33 descends, and the movable table 22 and cable holding holder 33 hold down the tip of the flat multiconductor cable 1. When the flat multi-conductor cable 1 is securely held down, the punch holder 34 is subsequently lowered, and the comb-like blades 341 housed between the comb-like protrusions 332 of the cable holding holder 33 release the flat multi-conductor cable 1. The inter-conductor recess 12 of the cable 1 is broken and the comb-like protrusion 222 of the movable table 22 is also fitted. FIG. 4A is a side view and a sectional view of the main parts showing this state. As a result, a desired slit 13 is formed in the interconductor recess 12 of the flat multiconductor cable 1. The chips generated at this time are discharged to the chip receiver 223 and retained there.

When punching is completed, the punch holder 34
is returned to its original position, and then the cable presser holder 33 is also temporarily returned to its original position. Once the cable presser holder 33 returns, the movable table 22 becomes free and begins to move backward by the drive mechanism 224. When the retraction of the movable table 22 is completed, the connector supply device 23
The pressure welding connector 4 is attached to the connector holder 24 by
It protrudes directly above and stops. Here, the connector holder 24 rises from the through hole 241 of the fixed die member 2 and receives the pressure contact connector 4 at the top of its head. FIG. 4b is a side view and a sectional view of the main part showing this state.

Next, the cable holding holder 33 descends again to hold down the flat multi-conductor cable 1. In this case, the conductor portion 14 of the flat multi-conductor cable 1 which is held down by the comb-like projections 332 of the cable holding holder 33
The bottom part is a space. Here, the connector holder 24 receives the pressure welding connector 4 on the top of its head.
further rises, and presses the pressure connector 4 against the conductor portion 14 of the flat multiconductor cable 1, which is held only by the comb-like protrusions 332 of the cable holding holder 33, as described above. Since the lower surface of the comb-like protrusion 332 of the cable holding holder 33 has the shape of the cable receiving recess at the top of the pressure welding connector 4 as described above, the conductor portion of the flat multi-conductor cable 1 is removed by this pressure welding operation. 14 is guided deep into the insulation displacement connector 4. As a result, the conductor portion 14 has its sheath broken by the pressure contact of the pressure contact connector 4, and is electrically connected to the corresponding pressure contact. FIG. 4c is a side view and a sectional view of the main parts showing such a state.

In this way, when the pressure welding of the pressure welding connector 4 to the flat multi-conductor cable 1 is completed, first the connector holder 24 is attached, and then the cable holding holder 33 is attached.
is restored, and then the cable grip holder 32 is returned to its original position and the intermediate member 3 is raised, thereby making it possible to easily take out the flat multi-conductor cable 1 to which the insulation displacement connector 4 has been pressed. Thereafter, by moving the stopper 26 to a predetermined position, the device returns to its initial state.
