Description

Detailed Description of the Invention (1) Object of the Invention [Field of Industrial Application] The present invention relates to a flat cable pressure welding method and device, and particularly relates to a flat cable pressure welding method and an apparatus for pressure welding the flat cable. This invention relates to a pressure welding device for pressure welding large contact terminal fittings.

[Conventional technology]

In recent years, electronic devices and the like have become smaller and lighter, and the flat cables and connectors used therein have also become smaller and lighter. The spacing between the conductors of a flat cable can be reduced relatively easily (for example, to 2.54 mm), but the spacing between the contact terminal fittings of the contact terminal fitting band that is directly pressure-welded to the conductor of the flat cable is created by press processing from a metal sheet material. In order to ensure sufficient contact spring pressure, the spacing between the conductors of a flat cable was set to be larger (for example, 5.08 mm).

Conventionally, a pressure welding method and apparatus for directly pressure welding a contact terminal fitting of a contact terminal metal band to the end of a flat cable of this type have been disclosed, for example, in Japanese Patent Publication No. 1973-
36316, one contact terminal fitting is pressed against one conductor at the end of a flat cable, the flat cable is moved by the distance between the conductors, and one contact terminal fitting is again pressed against one conductor. Ta.

The present invention provides a press-connecting device for a flat cable, comprising press-connecting means for simultaneously press-contacting a plurality of the contact terminal fittings to the end portions while the terminal fittings are inserted into the contact terminal fittings.

Further, in the present invention, the contact terminal fittings of the contact terminal fitting band are arranged at intervals that are an integral multiple of the conductor spacing of the flat cable, and the conveyance distance of the contact terminal fitting band by the conveying sprocket changes each time by at least the conductor spacing of the flat cable.

Reference numeral 10 denotes a push roller which is opposed to the conveying sprocket 4 via the contact terminal fitting band 2. The pushing roller 10 is rotatably mounted on a shaft 12 fixed to a mounting bar 11, and the contact terminal fitting band 2 is connected to the guide groove. This prevents it from surfacing from 3. Mounting bar 1
1 has a base pivoted to a stand 13,
A coil spring 14 stretched between the free end and the stand 13 facilitates the rotational movement and prevents the push roller 10 from applying more pressing force to the contact terminal fitting band 2. . Mounting bar 1
A detector 15 is disposed near the free end of the contact terminal metal band 1, and detects whether or not the push roller 10 is in a state of pressing the contact terminal fitting band 2. Driving of the step motor 6 is prohibited unless the detector 15 detects that the mounting bar 11 is rotated and the contact terminal metal band 2 is pressed by the push roller 10. Reference numeral 16 denotes a guide roller, which is disposed near the supply end side of the guide groove 3 in order to ensure the supply of the contact terminal metal band 2 from a supply source (not shown) to the guide groove 3.

A base plate 21 is connected to one side of the contact terminal metal feed rail 1, and has a guide groove 22 extending in a direction perpendicular to the guide groove 3. A cable holder 24 is disposed in the guide groove 22 and is slidably movable by a lever 23. 2
Reference numeral 5 denotes a cable guide formed on one side of the cable holder 24 in the sliding direction, and by abutting one side edge of the flat cable 26, the guide groove 3 is positioned in the extending direction. Reference numeral 27 denotes a cable pushing member disposed by a hinge 28 on the other side of the cable holder 24 in the sliding direction, and rotates around the hinge 28 against a coil spring 29 stretched between the cable holder 24 The flat cable 26 is moved along the cable guide 25.
After being positioned and arranged, it rotates around the hinge 28 again to hold down the flat cable 26. As a result, an appropriate force is applied to the flat cable 26 by the coil spring 29, thereby preventing its displacement. A cable stopper 30 is located at the front end of the cable holder 24 and positions the front end of the flat cable 26 when the cable holder 24 is in the retracted position, that is, when it is furthest away from the contact terminal fitting feed rail 1. A position detection plate 31 is protruded from one side of the cable cradle 24, and when the cable pedestal 24 is in the retracted position, the detector 32 is activated and in the forward position, that is, the cable pedestal 24 is in the contact terminal metal feed rail. 1, the detector 33 is activated. 34 is a solenoid attached to the lower surface of the base plate 21, and a solenoid 34 is connected to the cable holder 2.
4 is advanced when the foot switch (not shown)
The cable stopper 30 is caused to fall by attracting one end of the link 36, which is turned into an excited state by the pressure of The excitation state is maintained until the presence of the position detection plate 31 is detected twice and the detector 32 detects the presence of the position detection plate 31. After removing the flat cable 26, the foot switch (not shown) is pressed again. By releasing one end of the link 36, the cable stopper 30 is returned to its original position by the return spring 37.

Reference numeral 51 denotes an upper pressure welding punch, which is moved by an electric press 52 toward the contact terminal metal band 2 disposed in the guide groove 3 of the contact terminal metal feed rail 1 and placed on the lower pressure welding punch 53. A plurality of protrusions are formed on the pressure contact surface of the upper pressure contact punch 51 for pressure contacting each contact terminal fitting to the front end of the flat cable 26, and a plurality of protrusions are formed on the pressure contact surface of the lower pressure contact punch 53. A plurality of other protrusions are formed that cooperate with the protrusions on the pressure contact surface to press the contact terminal fitting to the front end of the flat cable 26. A lower pressure welding punch 5 is provided near the rear edge of the pressure contact surface of the upper pressure welding punch 51 together with the upper pressure welding punch 51.
A positioning pin 51a that is moved toward 3 is provided. A movable part 54 is formed in a part of the lower pressing punch 53, and is moved relative to the remaining part while resisting the buffer spring 55 when the upper pressing punch 51 is pressed. A portion of the contact terminal metal feed rail 1 is removed near the front edge of the lower pressure welding punch 53, that is, the portion facing the cable holder 24, and a recess 56 is formed.
It is said that Rear end portion 57 of lower pressure welding punch 53
is at the same height as the bottom surface of the guide groove 3 of the contact terminal metal feed rail 1, and guides the base of the contact terminal metal band 2. A guide member 58 is disposed at the rear end 57 of the lower pressure welding punch 53 at a slight distance from the surface thereof and guides the positioning pin 51a and fixes the base, that is, the edge portion of the contact terminal metal band 2 during pressure welding. . That is, by advancing the cable holder 24 toward the front edge of the lower pressure welding punch 53, the front end of the flat cable 26 is pushed into each terminal of the contact terminal fitting band 2 on the lower pressure welding punch 53, and then the upper pressure welding punch 51 is moved forward. Then, the positioning pin 51a is moved toward the lower press punch 53 by the electric press 52. The positioning pin 51a is inserted into the guide hole 5 at the base of the contact terminal fitting band 2 via the guide hole 59 of the guide member 58. Since the movable part 54 of the lower pressure welding punch 53 moves toward the base plate 21 due to the pressure welding of the upper pressure welding punch 51, the rear edge of the rear half of the pressure contact surface of the upper pressure welding punch 51 and the rear end portion 57 of the lower pressure welding punch 53 are then moved. The leading edge cuts and separates the connecting portion between the base of the contact terminal fitting band 2 and each contact terminal fitting. Further, the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 move toward the base plate 21, so that each contact terminal A metal fitting is pressed against the front end of the flat cable 26. Reference numeral 60 denotes a push plate that prevents the contact terminal metal band 2 from floating up from the contact terminal metal feed rail 1 in the vicinity of the lower pressure welding punch 53.

Furthermore, the operation of the pressure welding device of the present invention will be explained in detail.

First, the contact terminal metal band 2 is pulled out from the supply source and placed in the guide groove 3 of the contact terminal metal feed rail 1 via the guide roller 16, and the guide hole 5 at the base of the contact terminal metal band 2 is inserted into the conveying sprocket 4. engage. After rotating the mounting bar 11 to place the push roller 10 on the contact terminal fitting band 2, a foot switch (not shown) is pressed to drive the step motor 6. The step motor 6 is operated intermittently depending on the number of times the foot switch is pressed, and the conveying sprocket 4 is rotated intermittently. As a result, the contact terminal fitting band 2 is intermittently moved toward the lower pressure welding punch 53. When the contact terminal metal band 2 reaches a predetermined position on the lower pressure welding punch 53, the operation of the foot switch is terminated.

Next, the cable pushing member 27 is attached to the coil spring 29.
The flat cable 26 is lifted up against the force and released, and the flat cable 26 is placed on the cable holder 24. The flat cable 26 is positioned by abutting one side edge against the cable guide 25 and abutting the front end against the cable stopper 30. The cable pushing member 27 is closed and the flat cable 26 is pressed and held by the spring force of the coil spring 29. Thereafter, pressing another foot switch (not shown) energizes the solenoid 34 and lowers the cable stopper 30. After the cable stopper 30 is lowered, the lever 23 is held and the cable holder 24 is moved forward toward the lower pressure welding punch 53. The front end of the flat cable 26 is pushed into the pressure contact portion of each contact terminal fitting of the contact terminal metal band 2 on the lower pressure contact punch 53. When this state is detected by the detectors 32 and 33, the electric press 52 is driven and the upper press punch 51 is moved toward the lower press punch 53. Positioning pin 51a
is inserted into the guide hole 59 of the guide member 58 and then into the guide hole 5 at the base of the contact terminal fitting band 2.
Next, the movable part 54 of the lower pressure welding punch 53 moves toward the base plate 21 due to the pressure welding of the upper pressure welding punch 51, so that the rear edge of the rear half of the pressure contact surface of the upper pressure welding punch 51 and the rear end 5 of the lower pressure welding punch 53
The leading edge 7 cuts and separates the connecting portion between the base of the contact terminal metal band 2 and each contact terminal metal fitting. Since the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 continue to move toward the base plate 21, each contact occurs between the front half of the upper pressure welding punch 51 and the front half of the lower pressure welding punch 53, that is, the non-movable part. A terminal fitting is pressed into contact with the front end of the flat cable 26. At this time, the pitch, that is, the spacing between each contact terminal fitting of the contact terminal fitting band 2 is normally 5.08 mm, and the pitch, that is, the spacing between each conductor of the flat cable 26 is 2.54 mm, so the flat cable 2
This means that the contact terminal fitting is pressure-welded to the conductor numbered 6. When the pressing operation is finished, the upper pressing punch 51 and the lower pressing punch 53 return to their original positions.

The cable holder 24 is moved backward by the lever 23. When the cable holder 24 is in the retracted position, the step motor 6 is automatically driven and rotated by a predetermined pitch while being counted by the detector 9. As a result, the contact terminal fitting band 2 is placed on the lower pressure welding punch 53 at a half pitch, that is, 2.54 mm, from the position at the previous pressure welding.
It is assumed that the position is displaced by Thereafter, the cable pedestal 24 is moved forward again toward the lower pressure welding punch 53, and the same pressure welding operation as the previous time is repeated.

After the pressure welding operation is completed, grasp the lever 23 to move the cable holder 24 backward, and then move the cable pushing member 2
7 to open it and remove the flat cable 26 from the cable holder 24.

By pressing the other foot switch to raise the cable stopper 30 and repeating the above operation, the contact terminal fitting can be pressed into contact with a new flat cable.

Although the above description has been made assuming that the number of conductors in the flat cable is constant, the present invention can also be applied to processing flat cables having different numbers of conductors. That is, at least the cable holder may be made movable along the contact terminal fitting feed rail according to the number of conductors of the flat cable. This will be explained in more detail with reference to FIG.

21A is a base plate, and the contact terminal metal feed rail 1 is mounted on another base plate 71 connected to one side of the contact terminal metal feed rail 1.
It is slidably mounted by an air cylinder 75 via a rod 74 on guide rails 72 and 73 arranged parallel to the guide groove 3, and a guide groove 22A extending in a direction perpendicular to the guide groove 3 is bored. has been done.
In the guide groove 22A, there is a cable holder 2 which can be slid by an air cylinder 23B via a rod 23A.
4A is installed. 25A is cable cradle 2
The cable guide 4A is disposed on one side in the sliding direction, and the guide groove 3 is positioned in the extending direction by abutting one side edge of the flat cable 26. The cable guide 25A is slidably disposed in guide grooves 24B and 24C that are bored in a direction perpendicular to the sliding direction of the cable holder 24A, and extends in the direction in which the guide grooves 24B and 24C extend. A positioning screw 25C whose shaft is inserted into the elongated hole 25B with an extended shaft and screwed into a positioning hole 24D drilled in the cable holder 24A at a predetermined interval, for example, at an interval of the long axis of the elongated hole 25B. Therefore, it is positioned appropriately. Reference numeral 27A denotes a cable pushing member disposed by a hinge 28A on the other side of the cable holder 24A in the sliding direction, and rotates around the hinge 28A against a coil spring 29A stretched between the cable holder 24A and the cable holder 24A. After moving to position and arrange the flat cable 26 along the cable guide 25A, it rotates again around the hinge 28A to hold down the flat cable 26. As a result, an appropriate force is applied to the flat cable 26 by the coil spring 29A, thereby preventing its displacement. 30A is a cable stopper which is located at the front end of the cable holder 24A when the cable holder 24A is in the retracted position, that is, when it is farthest from the contact terminal metal feed rail 1, and which stops the flat cable 26.
Position the front end of the A position detection plate 31A is protruded from one side of the cable holder 24A.
When the cable holder 24A is in the retracted position, the detector 32A operates, and when the cable holder 24A is in the forward position, that is, when the cable holder 24A is closest to the contact terminal metal feed rail 1, the detector 33A operates. A solenoid (not shown) is attached to the lower surface of the base plate 21A, and the cable holder 2
When 4A is moved forward, one end of a link (not shown), which is energized by pressing a foot switch (not shown) and rotates around a fulcrum (not shown), is pressed against a return spring (not shown). The cable stopper 30A is dropped by suction, until the detector 33A detects the presence of the position detection plate 31A twice and the detector 32A detects the presence of the position detection plate 31A. is in an energized state, and after removing the flat cable 26, it is de-energized by pressing the foot switch (not shown) again, and by releasing one end of the link, the return spring causes the cable stopper 30A to
to return to its original position.

For other configurations, those explained in FIGS. 1 to 6 may be adopted.

In addition, the operation of the embodiment shown in FIG. 7 will be described in detail.

First, the contact terminal metal band 2 is pulled out from the supply source and placed in the guide groove 3 of the contact terminal metal feed rail 1 via the guide roller 16, and the guide hole 5 at the base of the contact terminal metal band 2 is inserted into the conveying sprocket 4. engage. After rotating the mounting bar 11 to place the push roller 10 on the contact terminal fitting band 2, a foot switch (not shown) is pressed to drive the step motor 6. The step motor 6 is operated intermittently depending on the number of times the foot switch is pressed, and the conveying sprocket 4 is rotated intermittently. As a result, the contact terminal fitting band 2 is intermittently moved toward the lower pressure welding punch 53. When the contact terminal fitting band 2 reaches a predetermined position on the lower pressure welding punch 53, the pressing of the foot switch is finished.

Next, the position of the cable guide 25A on the cable holder 24A is determined according to the width of the flat cable 26. That is, loosen the positioning screw 25C, move the cable guide 25A along the elongated hole 25B and guide holes 24B, 24C to an appropriate position, and fix by screwing the positioning screw 25C into an appropriate positioning hole 24D. do. After that, cable push member 2
7A is lifted up against the coil spring 29A to release it, and the flat cable 26 is placed on the cable holder 24A. The flat cable 26 has one edge in contact with the cable guide 25A and the front end in contact with the cable stopper 3.
The position is determined by contacting 0A. The cable pushing member 27A is closed and the flat cable 26 is pressed and held by the spring force of the coil spring 29A. Thereafter, by pressing another foot switch (not shown), the solenoid is energized and the cable stopper 30A is lowered. After the cable stopper 30A is lowered, the air cylinder 23B is operated and the cable holder 24A is moved through the rod 23A.
automatically advances toward the lower pressure welding punch 53. The front end of the flat cable 26 is pushed into the pressure contact portion of each contact terminal fitting of the contact terminal metal band 2 on the lower pressure contact punch 53. This state is the detector 32
When detected by A, 32A, the electric press 52 is driven and the upper pressure welding punch 51 is moved to the lower pressure welding punch 5.
Moved towards 3. The positioning pin 51a is inserted into the guide hole 59 of the guide member 58 and then into the guide hole 5 at the base of the contact terminal fitting band 2. Next, the lower pressure welding punch 5 is pressed by the upper pressure welding punch 51.
As the movable part 54 of No. 3 moves toward the base plates 21A, 71, the rear edge of the rear half of the pressure contact surface of the upper pressure contact punch 51 and the front edge of the rear end portion 57 of the lower pressure contact punch 53 move the contact terminal metal band 2. The connecting portion between the base of the contact terminal and each contact terminal fitting is cut and separated.
Since the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 continue to move toward the base plates 21A and 71, there is a gap between the front half of the upper pressure welding punch 51 and the front half of the lower half pressure welding punch 53, that is, the non-movable part. Each contact terminal fitting is attached to a flat cable 26.
is pressed against the front end of the At this time, the pitch or spacing between each contact terminal fitting of the contact terminal fitting band 2 is normally 5.08 mm, and the pitch or spacing between each conductor of the flat cable 26 is 5.24 mm. This means that the contact terminal fitting is pressure-welded to the contact terminal fitting. When the pressing operation is finished, the upper pressing punch 51 and the lower pressing punch 53 return to their original positions.

The cable holder 24A is moved back by the air cylinder 23B and the rod 23A. When the cable holder 24A is in the retracted position, the step motor 6 is automatically driven and rotated by a predetermined pitch while being counted by the detector 9. As a result, the contact terminal metal band 2 is placed in the same position on the lower pressure welding punch 53 as compared to the previous pressure welding position. On the other hand, cable cradle 2
4A is automatically moved to the right by a half pitch, that is, 2.54 mm, along the contact terminal metal feed rail 1 by the action of the air cylinder 75 and the rod 74. Thereafter, the cable holder 24A is moved forward again toward the lower pressure welding punch 53, and the same pressure welding operation as the previous time is repeated.

After the pressure welding operation is completed, the cable holder 24A is moved backward by the action of the air cylinder 23B and the rod 23A, and the contact terminal metal feed rail 1 is moved back by the action of the air cylinder 75 and the rod 74.
The cable support member 27A is automatically moved to the left by a half pitch, that is, 2.54 mm, to the initial position, and then the cable holding member 27A is lifted and released.
Remove flat cable 26 from A.

By pressing the other foot switch to raise the cable stopper 30A and repeating the above operation, the contact terminal fitting can be pressed into contact with a new flat cable.

In the above description, the space between the contact terminal fittings in the contact terminal fitting band is twice the distance between the conductors of the flat cable, but the present invention is not necessarily limited to this. For example, the spacing between the contact terminal fittings of the contact terminal fitting band may be another integral multiple of the conductor spacing of the flat cable, or may be in any other suitable relationship.

It is also clear that the cable stopper may be moved in response to a detector for detecting the movement of the cable cradle or in response to the movement of the cable cradle.

(3) Effects of the Invention As is clear from the above, the present invention is capable of simultaneously inserting the end portions of a single flat cable into a plurality of contact terminal fittings of a contact terminal fitting band and press-connecting the plurality of contact terminal fittings in one operation. Therefore, it has the effect of increasing the efficiency of the press-fitting work of the contact terminal fitting to the flat cable. Further, in the present invention, the contact terminal fittings of the contact terminal fitting band are arranged at intervals that are an integral multiple of the conductor spacing of the flat cable, and the conveyance distance of the contact terminal fitting band changes at least by the conductor spacing of the flat cable for each conveyance. The distance is the same for each predetermined number of conveyances, and each time the contact terminal metal strip is conveyed, the pressure welding means performs pressure welding, and the cable cradle moves the flat cable forward and backward, so there are only two pressure welding operations. However, it has the effect of allowing contact terminal fittings to be pressure-bonded to all conductors of a flat cable.
