Then woven electric wires 61 braid each is different due to the rotation of the intermediate rotor 64, for example, in such a state that the woven electric wire 61 on the side of the common clamp 62 is applied back tension (tension force). When this happens, because within an acceptable tolerance, there is a deviation in length, which should be cut woven electric wires 61, these woven electric wires 61 are twisted with each other so that the longer the electric wire 611a little slack, and the deviation of the length of woven electric wires 61 are reimbursed on a twisted plot, as shown in Fig.7(b). This reduces the accuracy of the step with which the rolled electric wires 61, and therefore it was not possible to verify that the condition of the twisted sections 61a same regardless of their positions along the length of finished cable 61' with twisted pairs. Because of this, the quality of the finished cable 61' with twisted pairs have to ensure by measuring bezprovodnogo gap and the characteristic impedance.

Description of embodiments

In Fig.1 to 3 shows one version of the implementation mechanism for the application of the inverse tension by twisting woven electric wires in accordance with this invention.

As shown in Fig.1, the mechanism 1 for the application of the inverse tension by twisting woven electric wires includes a pair of left and right clamps 2 electrical wires, a pair of left and right strip movable plates 3 of the grounds on which respectively set the clamps 2 electrical wires, rectangular General fixed plate 5 of the base, having a pair of left and right guide rails 4, to the th respectively introduced into sliding contact movable plate 3 of the base, and a pair of left and right long pneumatic cylinder 6, which are provided on left and right sides of the common stationary plate 5 of the base and in which the distal ends of the rods 6a are attached to the front ends of the respective movable plates 3 of the base by means of respective brackets 7.

Each element of the clamp 2, the movable plate 3 of the base, the guides 4, the pneumatic cylinder 6 and arms 7 are arranged symmetrically in the width direction. Each of the terminals 2 has a horizontal groove 9 for inserting electric wires having terminal end face (rear end face) 9a, which is located symmetrically in the width direction from a terminating end face (rear end face) 9a horizontal grooves 9 for inserting electrical wires in another clip 2 and with which the distal end 8a of each of the pair of left and right electric wire 8 is entered in the stop block section 10, in the upper surface of which is provided a groove 9 for inserting electric wires, section 10C of the recess provided in the inner vertical side wall 10b block section 10 in the anterior segment of the groove 9 for inserting electric wires, a vertically extending movable plate 11 to hold the electrical wires that goes to the site 10c cut so that still beats rivate distal end section of the electric wire 8 between the inner surface of the vertical inner wall 10d block section 10 and a, a cylindrical coil spring (spring member) 12, which deflects the plate 11 to hold the electrical wires to the inner wall 10d block of section 10, the operating lever 13, which can move forward and backward and which at its rear end attached to L-shaped and wedge-shaped sections 14 (see Fig.2), which are made as a unit with the operating lever 13 at its front part to clamp plate 11 to hold the electrical wires out of the opposition of the deflecting force of helical springs 12 so as to form a gap, which is equal to the diameter of the electric wire is greater than or between the plate 11 to hold the electric wire and the inner wall 10d block section 10.

The movable plate 3 of the base are positioned so that lie in the direction of width close to each other, and the terminals 2 are arranged such that they lie in the direction of width close to each other. As the movable plate 3 of the base, and the clamps 2 are separated in the width direction from each other relative to the Central narrow gap 15, as to the border. Terminal 2 is located on the front half of the corresponding movable plate 3 of the base, and one of the pair of left and right short pneumatic cylinder 16 is located on the rear half of the movable plate 3 grounds on which the question. A pair of pneumatic cylinders 16 are designed for automatic wound electrical wiring terminals 2. In the state shown in Fig.1, in which the electric wire is fixed (installed) in its place, the distal ends of the rods 16a short pneumatic cylinders 16 abuts the rear end faces 13a of the operating levers 13, which set aside. Pneumatic cylinders 16 are so located that they lie in the direction of width close to each other and separated in the width direction from each other with respect to the Central gap 17 as the border.

General fixed base plate 5 is made wider than the total width of the pair of left and right movable plates 3 of the base, and a pair of left and right guide rails 4 are arranged such that they pass from the rear end 5a to the position advanced further forward than the front end 5b of the total fixed plate 5 of the base (the front end sections of the rails 4 are as indicated by the position 4A). In addition, the respective rear surfaces of the movable plates 3 grounds provided input in sliding contact sections 18, which are inserted in sliding contact with the corresponding guide rails 4. On the rear end total fixed plate 5 installed base plate 20 of the braking, and the plate 20 braking Keitaro left and right braking lugs 20, in the emphasis with which entered the inhibitory projections 19 on the rear ends of the movable plates 3 of the base.

The main body 6b of the cylinder having a hollow cylindrical shape, a pair of left and right pneumatic cylinders 6 for the application of the inverse tension are still on the left and right sides of the front surface total fixed plate 5 of the base provisions that extended further outward in the width direction than the pair of moving plates 3 of the base so that these cylinders are from the rear end to the front end total fixed plate 5 of the base. The corresponding rods 6a pneumatic cylinders 6 are longitudinally forward, and then are connected respectively with the brackets 7, which act in the direction of the width at the respective front ends of the movable plates 3 grounds. In the state shown in Fig.1, in which the rods 6a pneumatic cylinder 6 is advanced to the electric wire 8 is not applied back tension, and therefore, the electric wire 8 SAG down. The clamps 2 are closed, holding the electric wire 8 side by side in the width direction at the same height.

In Fig.2 shows the state in which the terminals 2 are open. In the state shown in Fig.2, when the operator inserts one end parts of the electric wires 8 (see Fig.1) in ditches and 9 for inserting electrical wires in the terminals 2 and pulls the operating lever 13 back tapering wedge-shaped parts 14 are discharged together with the operating levers 13, so that the clearances between the inner walls 10d and the retaining plates 11 on block sections 10 are narrowed, leaving a gap equal to the diameter of the electric wire or smaller, and the electric wire 8 is still held between the inner walls 10d and the retaining plates 11 by means of the deflecting forces of the helical springs 12.

The corresponding rods 6a pneumatic cylinder 6 is disposed in a corresponding cylindrical main body 6b by means of respective pressure air pneumatic cylinder 6, as shown in Fig.3, from a state shown in Fig.1, whereupon the movable plate 3 of the base moving back along the corresponding guide rails 4 along with the corresponding rods 6a. Then the clamps 2 are moving back together with the corresponding movable plate 3 of the base, resulting in electric wires 8 are respectively applied back tension by appropriate clamps 2.

Even though the length of the electric wire 8 is changed, through the appropriate application of the reverse tension to the electric wire 8 as described above, the tension force applied to the electric wire 8 made of the same is (i.e., electric wires 8 are under tension the same forces), thereby preventing the formation of sagging due to the difference in length between the electric wires 8. Appropriate caps 6c pneumatic cylinder 6 can be connected with a common hose for compressed air. In Fig.3 shows that the corresponding rods 6a pneumatic cylinder 6 is not compressed completely, and still are, leaving a certain margin of the stroke, so that the electric wire 8, which is longer than expected, you can apply back tension.

In Fig.3 shows the state in which the electric wire 8 is installed on one of its ends. The other ends of the electric wire 8 is fixed individually by a pair of left and right cylindrical clamps 21 electrical wires or other electrical terminals), for example, as shown in the example in Fig.4. Each of the clamps 2, shown in Fig.4, includes a cylindrical wall 22, the groove 23 for inserting electric wires provided in the cylindrical wall 22 and having a surface 23a of the focus electric wires on the lead end holding section 24, which holds the tail part of the electric wire 8 is inserted into the groove for inserting the electric wire through otklonile the force of the spring, and the L-shaped operating lever 25, which passes at right angles to the cylindrical wall and which opens the holding area with resistance to deviating force of the spring. The terminals 2 are mounted to a common rotating plate 26, lying side by side in the width direction, and the rotating plate 26, in turn, is connected to the motor 27, so that the clamps 2 and the rotating plate 26 rotate together due to the excitation of the motor 27. The motor 27 is secured to the plate 28 of the base by a short rack 29.

In Fig.5(a) shows one mode of a method of manufacturing a cable with twisted pairs by applying a mechanism for the application of the inverse tension described above. As shown in Fig.5(a), the front and rear ends of long electric wire 81and short electric wires 82that, in the end, are cut with the achievement of different lengths that are within an acceptable tolerance cutting, respectively, are fastened in its place by the front and rear clamps 2, 21. The front (or other) clips 21 are arranged side by side in the direction from front to back, resulting position of the front ends of the electric wires 8 are equally governed by the clamps 21. The rear clamps 2 are forced to move by sliding back through the relevant paragraph is aumatically cylinder 6 (see Fig.3)and the rear clamp 2, holding a long electric wire 81and the rear clamp 2, holding short of the electric wire 82, are so located that they are separated from each other in the direction from front to back, with the first mentioned rear clamp 2 is back, and the last mentioned rear clamp 2 is in the front, resulting in a reverse tension is applied respectively to the electric wires 8, which are attached to the respective rear terminals 2.

In this state, for example, the rotor 30, which is located closer to the terminals 2 on the rear ends of the electric wire 8 is forced to move to the front clamps 21 at a constant speed, rotating in the same direction indicated by the arrow. The front clamps 21 are rotated by an electric motor 27 (see Fig.4) in the same direction and with the same speed as the rotor 31. Thus, the woven electrical wires 8 are twisted with each other between the rear clamps 2 and the rotor 30.

When twisting woven electric wires 8, as shown in Fig.5(b), the acceptable tolerance cutting between the woven electric wires 8 is compensated on the non-twisted section 8c on the side where the electric wire 8 is applied back tension (on the side of the rear end sections of electrical conductors 8). Then, pascalc the long electric wire 8 1has excess length L that is greater than what the short electric wires 82to the end, with steps between P twisted plots 8d woven electric wire 8 is made equal, and therefore is a ready-made cable with twisted pairs, which is then gently twisted through the same steps P on each twisted section 8d.

Thus, since the operating parameters of the product (cable 8' twisted pair) can be guaranteed only by measuring steps P operator, usually conducted measurement bezprovodnogo gap and the characteristic impedance becomes unnecessary. Position 31 in Fig.5(b) denotes the output of which is electrically connected with the front and rear ends of the electric wires 8 by means of the pressure contact.

In Fig.3 shows that although the length of the electric wires 8 are reduced by twisting woven electric wires 8, the value of (N) apply back tension can be controlled by regulating the pressure of air (control pressure air pneumatic cylinder 6 for the application of the inverse tension by means of a pneumatic regulator. The rods 6a pneumatic cylinder 6 is not moving, and is backward tension is regulated by means of pressure air. Air pressure applied to the stump the automatic cylinders 6, to realize the value of back tension, which is determined in advance depending on the diameter or type of electrical wires, and the adjustment is completed when it reaches the prescribed air pressure.

After twisting woven electric wires 8 as desired, the rods 6a pneumatic cylinders 6 nominated for the greatest distance, as shown in Fig.1, and retaining the electric wire clips 2 stops, as shown in Fig.2, so that the cable 8' twisted pairs can be extracted from the terminals 2. The clamps 2, you can decompress automatically, pushing short pneumatic cylinders 16, shown in Fig.1, to move the operating levers 13 forward.

In Fig.6 shows an example of a device 32 for the manufacture of cables with twisted pairs, is applied to the above-described mechanism for the application of the inverse tension.

Mechanism 1 for the application of the inverse tension executed the same on each of the three circumferential surfaces of one (rear) intermediate rotating element 33, which are provided in the circumferential direction at regular intervals. In Fig.6, item 2 refers to clamp the electric wire, position 16 denotes a cylinder for wound clamp, position 6 denotes a cylinder for the application of the inverse tension, position 3 indicates odijoo the base plate, and the position 5 indicates the total fixed the base plate. The three circumferential surface is formed by three General fixed plate 5 of the base.

A pair of clamps 21 electrical wires (other terminals of electric wires and a motor 27, similar to those shown in Fig.4, performed equally on three peripheral surfaces of the other (front) of the intermediate rotating element 34, which are arranged in the circumferential direction at regular intervals. The three circumferential surface is formed by three plates 28 of the base, similar to those shown in Fig.4. Intermediate rotating elements 33, 34 supported for rotation on the respective racks 35, 36 and together rotated one third of a full turn at a time by means of an intermediate driving device (for example, a pneumatic cylinder 37 and the means 38 braking torque). In each of the intermediate rotating elements 33, 34, circumferential surface located on the near side, attached to the plane 5, 28 installing electric wires circumferential surface located so that it is facing down, tied to the plane 52, 282curl woven electric wires, and the circumferential surface located on the far side, attached to the flat is 5 3, 283the release of woven wires.

Woven electric wire 8 (see Fig.3, 4) is fixed in its place by the front and rear clamps 2, 21 on the circumferential surfaces in planes 5, 28 installation of electrical conductors, and a reverse voltage is applied to woven electric wire 8 by means of a horizontal cylinder 6. Then, when the circumferential surface is rotated to the plane 52, 282curl woven electrical wires, rotor 30, which is cut so that it opens in a part of its circumferential surface, having an open area 30A of the recess, and which has a twisting shaft 30b mounted so that converts to an open area 30A of the recess, as shown in Fig.5(a), rises a vertical pneumatic cylinder (not shown) that is installed between the woven electric wires 8 (or woven electric wires 8 are inserted through the annular rotor 30). Then woven electric wires 8 are twisted with each other due to the simultaneous rotation of the rotor 30 and the electric motor 27. Then, when the circumferential surface is rotated to the plane 53, 283release cable with twisted pairs, automatically winding the tape around the front and rear ends of the cable 8' with twisted pairs (see Fig.5(b)), which is the production of ready-made cables with twisted pairs. This cycle is automatically repeated, resulting in the production of cables 8' twisted pairs occurs with acceptable efficiency.

Although an implementation option described as associated with the use of the rotor 30, you can borrow a configuration that does not involve the use of rotor 30, in which the terminals 21, shown in Fig.4, rotated by an electric motor 27 in such a state that one of the ends of the woven wires 8 are fastened in its place by the clamps 2, shown in Fig.3, and the other ends of the woven wires 8 are fastened in its place by clamps 21, shown in Fig.4, resulting woven electric wire 8 can be twisted between the terminals 2 and the clamps 21. The clamps 21, shown in Fig.4, refer to example retention woven electric wires 8, and therefore, can according to need to ask any shape or configuration, provided that there is a possibility respective stationary mounting woven electric wires 8' and the possibility of their rotation by an electric motor 27.

In addition, the clamping unit, which consists of terminals 2, 6 cylinder, 16 and plates 3, 5 bases, which are shown in Fig.3, that is, the mechanism 1 for the application of the inverse tension, can be rotated by an electric motor (not shown). In this case, the clamps 21, shown in Fig.4, the imp is a thread in the General form of clamp, which holds all the electrical wires 8. In addition, woven electric wire 8 can be braided with each other between the front and rear clamps 2, 21 by rotating only the intermediate rotor 30 without the use of an electric motor 27 on the side of the clamps. In addition, the clamps 3, shown in Fig.3, include for example holding woven electric wires 8, and therefore, can according to need to ask any shape or configuration, provided that there is a possibility respective fixed retention woven electric wires 8.

In addition, in Fig.1 shows that the main body 6b of the cylinder, available in pneumatic cylinders 6 for the application of the inverse tension, can be connected with the front ends of the movable plates 3 grounds, and rods 6a pneumatic cylinder 6 can be connected with the rear ends of the total fixed plate 5 of the base. In General, the pneumatic cylinder 6 may require only the connection of the movable plate 3 of the base with a total fixed plate 5 of the base.
