Consequently, when the wire elements that are joined together twisted to form a strand occurs as the twisting the linear metal objects further twisted at the connecting portion is, no unwinding, and thus the connection state be reliably maintained by twisting.

Preferably, when the linear metal objects are wires passing through Twisting a variety of wire elements are formed the twisting direction, wherein the end portions are connected to each other, set to match the twisting direction of the wire elements. Consequently, when the linear metal objects that communicate with each other Twisting can be linked as the twist between two strands is further twisted, unfurling occurs between the Leads do not open, and thus the twisting state can be on the Connection section can be reliably maintained.

Preferably after the linear metal objects are drilled together are connected, at least one extra length of the End sections that are not twisted together, by cutting off away. Consequently, the linear metal objects in a connection state without leaving an unnecessary extra length section are arranged.

Preferably becomes at least one of the end portions that are not twisted together are, in the direction opposite to an insertion direction for a subsequent step is bent, and an extra length section is cut off a portion of it as a curved training cutout to leave. Hence, if the linear metal objects that make up the Having connecting portion, in a subsequent step as a Intermediate introduced, a difficulty can be reliable be avoided, wherein the cut end portion somewhere gets stuck on a path for a subsequent step and then cut off.

Preferably after the twisting is performed, the connecting portion plastically deformed by applying a compressive force. consequently The degree of plastic deformation can be maintained by twisting and a winding in the diameter direction can be suppressed.

Further is a connection device for connecting linear metal objects according to the present invention, which are the above Solve problems, a connecting device for connecting of linear metal objects facing each other, comprising: a pair of second rotators rotatable about the same axial center are provided, each having a pair of holding portions, which are able to hold the linear metal objects, and um the axial center are arranged around; a pair of first rotators, those with teeth running along the perimeters of the second Rotators are arranged, are engageable; driven Bevel gears with the corresponding first rotators to turn; and a drive bevel gear that is driven with the two Bevel gears is engaged, wherein by means of rotation of the Drive bevel gear the driven bevel gears in opposite Directions are rotated, with the rotations thereof to the second Transfer rotators via the first rotators and the second rotators in the opposite directions be rotated, whereby end portions of the linear metal objects, which are held by the holding sections, between the second Rotators are twisted.

Furthermore, the above-described Connecting means further comprising: a pair of second rotators, which are engaged with the corresponding first rotators, which are provided for rotation about the same axial center, and wherein each of which has a pair of retaining elements which are around the axial Center are arranged around and are capable of, the linear metal object to hold so that among the linear metal objects a linear Metal object used as a main wire nearby a center of rotation, compared to a linear metal object, which is used as a secondary wire, and so that the linear metal objects are suspended in such a way that the Environments of the end portions thereof overlap each other in the axial direction; and a constraint element of the linear object for constraint the linear objects that are between the pair of second rotators are suspended, in the diameter direction outwards to move. Further, by means of rotation of the drive bevel gear the driven bevel gears in the opposite directions rotated, with the rotations thereof to the second rotators via the first rotators are transmitted, and the second Rotators are rotated in opposite directions, causing the end portions of the linear metal objects are twisted together while these are from the constraint element of the linear object are limited in the diameter direction to move outward between the second rotators.

According to the Connecting device for connecting linear metal objects, which has the structure described above become the environments the end portions of the main wire and the sub wire accordingly held by the holding sections and hung in between, to overlap in the axial direction, and in the As described above, the drive wheel is rotated. consequently the second rotators become relatively in opposite directions through the driven bevel gears, the discs, and the rotated first rotators, and between these second rotators The connection can be made by twisting the sub wire around the main wire be done. Furthermore, as a simple structure without use a particular mechanism or the like is applied the installation costs are significantly reduced.

Further, since the restricting member of the linear object for restricting the main wire and the sub wire suspended between the pair of second rotators to move outward in the diameter direction, when the main wire and the sub wire are twisted together, the main wire and the sub wire are clamped to move outward in the diameter direction, and can be stably fixed along the twisting rotational axis, and thus, while avoiding winding and decentering, the main wire and the sub wire can become uniform and be twisted together. In this step, since the main wire is disposed near the center of rotation side, as compared with the by-wire, the main wire and the sub wire are neither uniformly nor evenly overlapped, screwed and twisted together, and thus a connection is made so that the sub wire around the Main wire is wound. Consequently, it can be suppressed that the strength of the connection portion deteriorates. That is, the main wire 3 may be responsible as a central conduit for an anti-traction load, and the sub-wire 4 may be responsible as a lateral or lateral line for anti-slip properties.

Preferably Furthermore, an electric heating means is provided which only heats the connecting portion after the end portions of the linear Metal objects are twisted together. Consequently, after the Compound is performed while the linear Metal objects are set in the connection device, can Steps involving heating or annealing are performed become.

Consequently, by simply introducing the linear metal objects in the slots the linear metal objects by means of the holding sections, which are formed as slots, being held.

Preferably opens each of the slots between teeth, the outer Circumference side of each second rotator are arranged with engage those of the corresponding first rotator are. As described above, since the slots, which the holding sections are for holding the linear metal objects, between the teeth that open to the outside Circumferential sides of the second rotators are provided, which with those the corresponding first rotators are to be engaged, can, compared to the case in which the slot on a position is formed at which a tooth is provided, the teeth of the second rotator reliably with which are brought into engagement with the corresponding first rotator. It can also reduce the life of the teeth and a power transmission failure from the first one Rotator be suppressed.

Preferably are the first rotators with the corresponding driven bevel gears united. Consequently, a reduction in the number of components and a simplification of the structure are carried out and costs can be further reduced.

Preferably are the first rotators with the corresponding driven bevel gears with a space in between or concentrically united.

Preferably is between the second rotators an intermediate piece, the has a predetermined length extension provided. Consequently, the linear metal objects can be a predetermined Length are twisted together, and further, the Twisting can be carried out more uniformly.

Preferably the intermediate piece is a restriction element of the linear object. As described above, when the restriction member of the linear object and the intermediate piece as an element are formed, the number of components can be reduced, and the structure of the device can be simplified.

Preferably the number of teeth of each first rotator is smaller as the number of teeth of each driven bevel gear. Consequently, since the rotational force of the first rotator, the smaller one Number of teeth has the driven bevel gear, is transmitted to the corresponding second rotator, can by increasing the transmission torque the twisting torque can be increased.

advantages

According to the present invention, since the vicinities of the end portions of the linear metal objects are held by the holding portions of the rotators to be suspended therebetween so as to overlap the vicinities of the end portions of the linear metal objects in the axial direction, and because the rotators are relatively in opposite directions Directions between the holding sections of the rotators as a rotation center around it, the linear metal objects are twisted together as if screwed together, making the connection easy. Further, the linear metal objects, which are uniformly twisted together, are firmly bonded together by a frictional force generated therebetween. Further, since the connection can be made by simply rotating the rotators having the holding portions in the opposite directions, a joining operation can be easily performed at a low cost. Further, since the diameter shape forming rate of the twisted portion can be brought to about 100% by annealing, the connection can be made firmly by means of a frictional force generated therebetween.

At this connection section 2 are the linear metal objects 1 twisted equivalently to each other and at this twisted section are the linear metal objects 1 plastically deformed and united together.

The linear metal objects 1 which are equivalently twisted together are strongly connected by a frictional force generated therebetween by the twisting.

Further, as it is in 1 (b) is shown in the case where after forming a bent portion 1 (b) by bending the end section 1 (a) of the linear metal object 1 at an insertion direction side of the connection portion 2 is arranged, in the direction opposite to the insertion direction, an extra length section removed by cutting, to a part of the end portion 1a having a length of 3 to 10 mm, which is used as a bent forming portion, removed by cutting, and this linear metal object 1 is introduced as an intermediate for a subsequent step in a path (in the direction shown by the arrow in the figure), whereby a difficulty can be reliably avoided, in which the connecting portion 2 is separated when the cut end portion 1 (a) gets stuck somewhere and creates an excessive load on it.

In the upper case 23 are on a side plate 23a and the other side plate 23b transmission gears 51a and 51b provided correspondingly at positions facing each other, and these transmission pinions 51a and 51b are designed to make waves 52a and 52b of it accordingly at the side plates 23a and 23b by means of bearings 53a and 53b are rotatably mounted.

Each of these transmission pinions 51a and 51b has a first spur gear 54 and a driven bevel gear 55 on, and the first spur gears 54 are designed to work with the second spur gears 41a and 41b to be engaged.

Further, on a roof plate 23c of the upper case 23 a drive bevel gear 56 provided, and this drive bevel gear 56 stands with the driven bevel gears 55 the transmission pinion 51a and 51b engaged. In this drive bevel gear 56 becomes a wave 57 of which rotatable from a bearing 59 stored, that at the roof plate 23c is provided, and at an end portion of the shaft 57 located on the upper surface side of the roof panel 23c protrudes, opposite the drive bevel gear 56 , is a handle 58 intended. Further, by holding and turning this handle 58 the drive bevel gear 56 turned. In this embodiment, the driven bevel gears 55 and the drive bevel gear 56 Spiral bevel gears.

The number of teeth of the drive bevel gear 56 For example, is 20, the number of teeth of the bevel gear 55 and the first spur gear 54 from each of the transmission sprockets 51a and 51b for example, each 40, and the number of teeth of the second spur gears 41a and 41b for example, each 24, and the number of teeth of freewheeling pinion 31a and 31b are, for example, each 12. In this case, if the drive bevel gear 56 is rotated twice, the transmission pinions rotate 51a and 51b once. Furthermore, if the transmission pinion 51a and 51b are rotated three times, rotate the second spur gears 41a and 41b five times.

Next, a method for connecting the linear metal objects 1 using the above connection means 11 described.

First, from the two sides of the connection device 11 the end sections 1a the linear metal objects 1 in the corresponding slots 44 the second spur gears 41a and 41b in the case 41 introduced and these extend outwardly by a predetermined length through the through holes 43 the second spur gears 41a and 41b which are arranged on the opposite sides.

Alternatively, after the second spur gears 41a and 41b from the case 21 the connection device 11 are removed, the linear metal objects 1 placed in the spur gears, and the wheels are again at the predetermined positions in the housing 21 arranged.

In the state described above becomes the handle 58 the connection device 11 held and turned. Consequently, the drive bevel gear becomes 56 rotated and by means of this rotation, the transmission pinions 51a and 51b turned in opposite directions. Further, the rotations of the transmission pinion 51a and 51b to the second spur gears 41a and 41b transferred, and the second spur gears 41a and 41b are turned in opposite directions.

Consequently, the linear metal objects become 1 passing through the through holes 43 and the slots 44 the second spur gears 41a and 41b be limited or clamped, twisted in between. In this step, the linear metal objects 1 to the connection section 2 pulled by twisting, and a force that is the distance between the second spur gears 41a and 41b reduced, is generated; however, since the intermediate piece 45 interposed, the second spur gears become 41a and 41b maintained at the predetermined positions, and thus, a uniform twisting can be performed.

Further, since the intermediate piece 45 at the position in the vicinity of the outside of the linear metal objects 1 is arranged between the two spur gears 41a and 41b In the diametric direction, when a twist is performed, the linear metal objects are constrained to move outward in the diameter direction. That is, even if the linear metal objects 1 tend to spiral (or decenter) during twisting, become the linear metal objects 1 is brought into contact with the inner peripheral surface of the intermediate piece 40, and by means of this contact resistance become the linear metal objects 1 along the twist axis (along the rotation shaft of the second spur gears 41a and 41b ) stably fixed. Consequently, the linear metal objects can 1 be twisted uniformly and firmly together. Further, after the twisting is performed by a predetermined number, the handle 58 stopped to stop the twisting.

Next, as it is in 4 is shown in the state in which the connecting portion 2 by twisting together the linear metal objects 1 is formed, the terminals h1 and h2 of a heater H, which is used as an electric heating means, in the connecting device 11 is provided, with the end sections 1a the linear metal objects 1 connected. Thereafter, by setting at the switch of the heater H, electricity is supplied between the terminals h1 and h2, and by the electrical resistance of the connecting portion 2 itself, the twisted portion is heated to 250 to 500 ° C, and preferably to about 400 ° C, and maintained for at least 10 seconds or more and preferably for about 20 seconds for annealing. Consequently, a diameter performing percentage of the connection portion 2 be brought to about 100%.

Next, turn the upper case 23 using the joint 24 the upper portion of the lower housing 22 opened and the second spur gears 41a and 41b in the lower case 22 be brought out.

The second spur gears 41a and 41b are moved in the directions to be apart, and the end portions 1a the linear metal objects 1 be from the passages 43 the second spur gears 41a and 41b pulled out. Further, the linear metal objects become 1 out of the slots 44 the second spur gears 41a and 41b further pulled out, and the intermediate piece 45 is done by extracting the linear metal objects 1 from the notch section 46 removed from it.

Thereafter, non-twisted portions of the end portions 1a extending from the connecting section 2 extend, cut off by means of a pair of pliers, a clipper or the like.

Consequently, the linear metal objects 1 uniform with each other at their end portions 1a twisted and are by means of plastic deformation of the twisted connection section 2 united so that a tight connected state can be obtained.

Further, without performing annealing, the connecting portion 2a after twisting with a soft metal of low melting temperature 12 be firmly fixed as it is in 2 is shown. Consequently, unwinding of the connecting portion 2 can be avoided, and further, a close connection state can be obtained.

As described above, according to this embodiment, the surroundings of the end portions become 1a the linear metal objects 1 held by holding portions, which from the through holes 43 and the slots 44 the second spur gears 41a and 41b are formed and intervene so as to overlap each other in the axial direction, and the second spur gears 41a and 41b are rotated relatively in opposite directions. Consequently, between the second spur gears 41a and 41b the linear metal objects 1 simply and uniformly twisted together and plastically deformed at low cost, so that a firm connection is achieved.

Further, since the through holes 43 and the slots 44 the second spur gears 41a and 41b as the holding sections for the linear metal objects 1 can be used by introducing the linear metal objects 1 in the slots 44 the linear metal objects 1 simply by means of the holding sections that come out of the slots 44 are trained to be held. Further, if the linear metal objects 1 by being incorporated into the passages 43 The outer perimeters of the linear metal objects can be held 1 Reliable by means of the inner peripheries of the through holes 43 be held, elect the linear metal objects 1 can be twisted together, and a uniform twist can also be achieved.

Furthermore, the intermediate pieces serve 45 as the constraint element of the linear object, and in the state in which the linear metal objects 1 that are suspended between a pair of rotators are constrained to move outward in the diametric direction, and the linear metal objects 1 are twisted together. Consequently, the linear metal objects can 1 along the twist axis are stably fixed, and while unstable moving and swinging is avoided, the linear metal objects can 1 be twisted uniformly and firmly together.

Further, by supplying electricity and using the heater H between the end portions 1a of the connection section 2 By means of co-twisting the linear metal objects 1 is formed, the connecting portion 2 heated in the connecting device, heated to a temperature of 250 to 500 ° C and maintained for 10 seconds or more for annealing. Consequently, the diameter shape forming rate of the connection portion 2 be brought to about 100% by the simple heater, so that the contact resistance of the connection portion can be improved.

Further, since the connection means 11 which are the linear metal objects 1 interconnected, has a simple structure that does not use any special mechanism or the like, the installation costs can be significantly reduced. Further, since the restricting element of the linear object and the intermediate piece 45 As an element, the number of components can be reduced, and the device structure can be simplified. Furthermore, the intermediate piece 45 and the restriction element of the linear object may be provided separately.

In particular, because the slots 44 acting as the holding sections for holding the metal linear objects 1 used to be open between teeth, on the outer peripheral sides of the second spur gears 41a and 41b are provided, which with those of the first spur gears 54 the transmission pinion 51a and 51b can be engaged, compared to the case in which the slots are formed at the tooth positions, the teeth of the second spur gears 41a and 41b Reliable with those of the first spur gears 54 be engaged. Further, a reduction in the tooth life and a transmission defect of power from the transmission pinions 51a and 51b be suppressed.

Because the transmission pinion 51a and 51b each of which is the first spur gear 54 and the driven bevel gear 55 can be used, a reduction in the number of components and a simplification of the structure can be achieved, and also a cost reduction can also be achieved.

Further, as the pairs of freewheeling pinions 31a and 31b on the sides opposite the transmission pinions 51a and 51b are provided, and with the second spur gears 41a and 41b are engaged so that these rotatably the second spur gears 41a and 41b store or support, can by means of freewheeling pinion 31a and 31b along with the transmission pinions 51a and 51b the second spur gears 41a and 41b be worn rotatably and releasably without the use of bearings or the like.

Further, since the intermediate piece 45 having a predetermined length between the second spur gears 41a and 41b is provided, the linear metal objects can be twisted with a predetermined length for connection, and further, the twisting can be further uniformly performed.

Furthermore, because the linear metal objects 1 firmly by means of the soft metal low melting temperature 12 at the connecting portion 2 fixed to each other or fixed, can be a unwinding of the linear metal objects 1 can be suppressed and further, the contact resistance of the connecting portion 2 be improved.

In this embodiment, although the case in which the linear metal objects 1 each formed of a single wire being connected together as the linear metal objects 1 which have been described by way of example, twisted wires, each formed by twisting a plurality of wire elements, may also be used. In the case described above, the twisting direction becomes when the end portions 1a are connected together, preferably set so as to coincide with the twisting direction of the wire elements. Consequently, further, if the linear metal objects 1 twisted to the connection, a twist of two ver Twisted wires performed, and thus the connection condition can be reliably maintained by the twisting.

Further, in the case where a plurality of linear metal objects 1 which are twisted in advance, twisted for connection to form a twisted wire, the twisting direction when the end portions 1a connected to each other, preferably set to coincide with the twisting direction when the twisted wire is formed. Consequently, if a variety of linear metal objects 1 twisted together, the state of the connecting portion 2 the linear metal objects 1 be reliably maintained.

Further, like the above connection method, although the case where the end portions 1a a pair of linear metal objects 1 can be interconnected, described by way of example, even if the linear metal object 1 having a circular shape, the above method of course also for connecting two end portions 1a of the linear metal object 1 be applied.

Further, in a circular metal rope, by means of twisting the linear metal objects 1 are formed while being wound in a circle when end portions of a metal linear object 1 interconnected, linear metal objects 1 that are not connectable, different from the linear metal object 1 which is to be connected, hooked by means of a plurality of pins, and these pins are moved in the direction to move from the linear metal object to be connected 1 to be away. Consequently, the compound is preferably performed in the state where the linear metal object 1 To connect from linear metal objects 1 that are not connected to, is located remotely.

Next, referring to the 5 to 7 A preferred second embodiment of the present invention is described.

As it is in 5 (a) is shown in a linear metal object 10 a main wire 3 which is a base wire screwed by a small twist having a long wavelength period, and a sub wire 4 which is a winding wire that connects to the main wire 3 twisted by a large twist, which has a shorter wavelength period than that of the main wire 3 has, with each other at the end portions 5 and 6 of which at a connecting section 7 connected. At this connection section 7 while the main wire 3 and the side wire 4 twisted together, the twisting is done so that the secondary wire 4 around the main wire 3 is wound. At the twisting section become the main wire 3 and the side wire 4 mutually plastically deformed and firmly connected to each other by means of a frictional force generated therebetween.

Further, as it is in 5 (b) is shown in the case where, after a bend portion 5a by bending the end section 5 of the linear metal object 10 at an insertion direction side of the connection portion 7 is arranged, is formed in the direction opposite to the insertion direction side, an extra length section is removed by cutting to a part of the end portion 5 having a length of 3 to 10 mm used as a bent forming portion, and this linear metal object 10 is introduced as an intermediate in a route for a subsequent step (in the direction shown by the arrow in the figure), a difficulty can be reliably avoided in which the connecting section 7 is separated when the cut end portion 5 somehow hooked and generates an excessive load that rests against it.

The main wire 3 For example, it is formed of a plastically deformable material, such as steel, copper or aluminum. Further, as in the case of the main wire 3 , is also the secondary wire 4 formed using a plastically deformable material, such as steel, copper or aluminum. As a result, a twisted shape of the main wire becomes 3 and the sub wire 4 maintained, and even if a tensile force or the like on the linear metal object 10 is applied, the connection state can be firmly maintained. Further, like the linear metal object 10 For example, various types of linear objects such as a single wire element, a twisted wire (stranded wire), and a multi-twisted strand (rope) formed by twisting together twisted wires may be used.

Further, in the linear metal object 10 the main wire 3 and the side wire 4 at the connecting portion 7 by means of a soft metal of low melting temperature 8th firmly attached to each other. As a soft metal low melting temperature 8th For example, it is preferable to use a copper-tin alloy be used (Lot). In 5 are the individual edge sections between the twisted head wire 3 and secondary wire 4 with a soft metal of low melting temperature 8th soldered by wetting, leaving the main wire 3 and the side wire 4 are firmly fixed together; however, the entire connecting section may be 7 with a soft metal of low melting temperature 8th be covered for a firm fixation or attachment.

As described above, since the main wire 3 and the side wire 4 with the soft metal low melting temperature 8th are firmly fixed to each other, can be a unwinding of the main wire 3 and the sub wire 4 at the connecting portion 7 can be suppressed, and further, the contact resistance of the connecting portion 7 be improved. Further, as a fixing means for the main wire 3 and the side wire 4 instead of the soft metal of low melting temperature 8th also a bonding agent can be used.

Next, referring to the 6 and 7 a connector that is used to connect the linear metal object 10 is used described.

As it is in 6 and 7 is shown contains this connection means 60 primarily a housing 61 , a drive bevel gear 62 , a pair of driven bevel gears 63 and 64 , a pair of slices 65 and 66 , first spur gears 67 and 68 which are a pair of first rotators, second spur gears 69 and 70 which are a pair of second rotators having a small diameter and two pairs of free-running pinions 71 and 72 that are free-running rotators. Further, in this embodiment, the drive bevel gear 62 and the driven bevel gears 63 and 64 straight bevel gears.

The housing 61 is from a lower case 73 and an upper housing 74 formed above the lower housing 73 is provided, and the lower housing 73 and the upper case 74 are pivotable with a joint 75 connected with each other. In the lower case 73 are the second spur gears 69 and 70 and the freewheeling pinions 71 and 72 recorded, and in the upper case 74 are the drive bevel gear 62 , the driven bevel gears 63 and 64 and the discs 65 and 66 and the first spur gears 67 and 68 added.

In the drive bevel gear 62 is a wave 76 on a roof tile 78 of the upper case 74 about a camp 77 stored. The drive bevel gear 62 is by turning a handle 79 attached to an end portion of the shaft 76 is provided, turned. The number of teeth of the drive bevel gear 62 is for example 20 (20T). The drive bevel gear 62 stands with the driven bevel gears 63 and 64 engaged.

The driven bevel gears 63 and 64 have waves 80 and 81 correspondingly perpendicular to the shaft 66 of the drive bevel gear 62 on, being the wave 80 these waves on a side plate 83 of the upper case 64 by means of a warehouse 82 is rotatably supported, and the other shaft 81 on the other side plate 85 of the upper case 74 about a camp 84 is rotatably mounted. The number of teeth of each driven bevel gear 63 and 64 is for example 40 (40T).

The disks 65 and 66 are correspondingly integral and concentric with the driven bevel gears 63 and 64 each having a predetermined thickness dimension T1 and about the same diameter as that of each driven bevel gear 63 and 64 on. Further, after separately forming, the discs may 65 and 66 on the driven bevel gears 63 and 64 fixed accordingly fixed.

The first spur gears 67 and 68 are correspondingly integral and concentric with the discs 65 and 66 connected. Because the first spur gears 67 and 68 outside the driven bevel gears 63 and 64 with the discs 65 and 66 having a thickness dimension T1 interposed therebetween becomes a relatively large space dimension L1 between the first spur gears 67 and 68 educated. The numbers of the first bevel gears 67 and 68 For example, each is 32 (32T).

The second spur gears 69 and 70 are with the space dimension L1, between the first spur gears 67 and 68 is formed, arranged, and stand with the first spur gears 67 and 68 according to engaged.

At an eccentric position in the vicinity of the center of each of the second spur gears 69 and 70 is a passage opening 86 which has a diameter slightly larger than that of the sub-wire 4 is formed as a kind of a holding portion, and this through hole 86 is designed to the side wire 4 to allow to step through.

Further, in each of the second spur gears 69 and 70 a slot 78 which is used as the other type of holding portion that opens between the teeth provided on the outer circumference of each of the upper pinions, formed by cutting at a position located slightly outside of the rotation center, the position as a bottom portion of the slot is used. The slot 78 has a width dimension slightly larger than the diameter of the main wire 3 is and is designed to be the main wire 3 from the open portion provided on the outer peripheral side can be inserted therein. Further, though this slot 87 is formed such that a part thereof is slightly angled in the vicinity of the bottom portion, this angled direction is changed according to the twisting direction when a connection is made, and is formed such that the main wire inserted in the vicinity of the bottom portion, can hardly be offset in the diameter direction to the outside. Ie. the design is such that the main wire 3 simply at the bottom portion of the slot 87 is held. In this case, the amount of eccentricity of the center of the bottom portion of the slot is 87 from the center of rotation of the second spur gears 69 and 70 smaller than the eccentricity amount of the center of the through hole 86 from the center of rotation of the second spur gears 69 and 70 ,

The passage openings 86 , the slots 87 and the surrounding area of the second spur gears 69 and 70 are by means of concave sections 90 and 91 exposed along the upper edges of the two side panels 88 and 89 of the lower case 73 are formed.

Furthermore, between the two spur gears 69 and 70 a hollow cylindrical intermediate piece 62 used as a holding portion having the space dimension L1 formed so that the rotation center thereof is coaxial with the second spur gears 69 and 70 is. The intermediate piece 92 has a notch section 93 which is formed in a part of the circumference thereof along the axis direction.

The second spur gears 69 and 70 have protrusions 94 and 95 which face each other at the rotational center position thereof, and these projections 94 and 95 are in the intermediate piece 92 fitted. Furthermore, by means of this intermediate piece 92 the second spur gears 69 and 70 arranged at predetermined positions with the space dimension L1 therebetween.

Further, since the inner diameter of the intermediate piece 92 is designed to be slightly larger than the dimension that is obtained when the main wire 3 and the side wire 4 bundled together, serves the intermediate piece 92 as a restricting element of the linear object for restricting the main wire 3 and the sub wire 4 that between the pair of second spur gears 69 and 70 hang to move outward in the diameter direction. The inner diameter of the intermediate piece 92 For example, it is 2.2 times the outer diameter of the main wire 3 or the sub wire 4 ,

In the free-running pinions 71 and 72 is a pair of waves 96 and a pair of waves 97 rotatable on the two side plates 88 and 98 of the lower case 73 over camp 98 and 99 rotatably mounted accordingly, and a pair of free-running pinions 71 and a pair of freewheeling sprockets 72 Each pair is provided with a space therebetween, corresponding to the second spur gears 71 and 72 engaged. Because every free-running pinion 71 . 72 a number of teeth of, for example, 12 (12T) and in the lower housing 73 is arranged store the freewheeling pinion 71 and 72 the second spur gears 69 and 70 rotatable.

The connection device 60 Forms a pinion brake mechanism, by means of the drive bevel gear 62 , the driven bevel gears 63 and 64 that with the drive bevel gear 62 engaged, the first spur gears 67 and 68 that with the driven bevel gears 63 and 64 are coupled and the second spur gears 69 and 70 that with the first spur gears 67 and 80 are engaged. In this case, as the number of teeth of the drive bevel gear 63 20 is the number of teeth of the driven bevel gears 63 and 64 40 is the number of first spur gears 67 and 68 32 is and the number of second spur gears 69 and 70 32, a rotational force is applied to the drive bevel gear 62 is applied, so to the driven bevel gears 63 and 64 transmit that the rate slows down and the torque is increased. Consequently, a relatively higher torque is applied to the first spur gears 67 and 68 that with the driven bevel gears 63 and 64 are engaged, and to the second spur gears 69 and 70 transferred with the first spur gears 67 and 68 are engaged.

Next, a joining method for producing the linear metal object 10 using the connection device 60 described.

First, the main wire 3 in the slot 87 of the second spur gear 69 by opening the upper housing 74 the connection device 60 or through the concave section 90 of the lower case 73 without opening the upper housing 74 introduced, and the end portion 5 of the main wire 3 is through the passage opening 86 the other second spur gear 70 over the intermediate piece 92 pulled out by a predetermined length.

Next is from the side opposite to the direction of insertion of the main wire 3 the secondary wire 4 in the slot 87 the other second spur gear 70 introduced and the end section 6 of the sub-wire 4 is through the passage opening of the second spur gear 69 over the intermediate piece 92 pulled out by a predetermined length.

Then the handle becomes 79 the connection device 60 rotated by applying a torque. The rotational force is applied by a hand or a power source, not shown in the figure. If the handle 79 starts to turn, as the drive bevel gear 62 is rotated by means of this torque, the driven bevel gears 63 and 64 turned in opposite directions. In this step, the slices 65 . 66 and the first spur gears 67 and 68 in the same directions as the corresponding driven bevel gears 63 and 64 turned, and the second spur gears 69 and 70 are turned in the opposite directions.

Because the second spur gears 69 and 70 turned in the opposite directions becomes the main wire 3 that of the second spur gear 69 to the other second spur gear 70 passes through and at the bottom portions of the slots 87 is arranged, by means of a small twist, which has a long wavelength period, screwed and at the same time is the sub-wire 4 from the other second spur gear 70 to the second spur gear 69 passes through and in the through holes 68 is arranged to the main wire 3 with a large twist, which has a short wavelength period screwed. In this step, there is a pulling force on the main wire 3 by means of a tension applying roller, not shown in the figure, and the sub-wire 4 a tensile force from the resistor to the intermediate piece 92 is the tensile load ratio of the main wire 3 to the secondary wire 4 set to the range of 10: 3 to 10: 6. Consequently, the main wire 3 and the side wire 4 by twisting each other to the connecting portion 7 drawn.

In this step, although the force acts, the distance between the second spur gears 69 and 70 to decrease, since the intermediate piece 92 is provided between, while the second spur gears 69 and 70 maintained at predetermined positions, the twisting performed.

Further, since the intermediate piece 92 at the position in the vicinity of the outside of the main wire 3 and the sub wire 4 is arranged between the second spur gears 69 and 70 hang, when the twisting is done, are the main wire 3 and the side wire 4 limited in the diameter direction with respect to the movement in the diameter direction to the outside. Ie. even if the main wire 3 and the side wire 4 These tend to curl (or decenter) during twisting, becoming with the inner circumferential surface of the intermediate piece 92 brought into contact, and by this contact resistance become the main wire 3 and the side wire 4 along the twist axis (along the rotation shafts of the second spur gears 69 . 70 ) stably fixed. Consequently, the main wire can 3 and the side wire 4 be twisted firmly together. Further, after the twisting is performed with a predetermined number, the handle 79 stopped to stop the twisting.

Next, as it is in 7 is shown in the state in which the connecting portion 7 by twisting the main wire 3 and the sub wire 4 which is the linear object 10 is formed, the terminals h1 and h2 of the heater H, which is used as an electric heating means, in the connecting device 60 is provided, with the end sections 5 and 6 of the linear metal object 10 connected. Thereafter, by setting at the switch of the heater H, electricity is supplied between the terminals h1 and h2 and by means of the electrical resistance of the connecting portion 7 itself, the twisted sections are heated to 250 to 500 ° C and preferably 400 ° C and maintained for at least 10 seconds or more and preferably for about 20 seconds for annealing. Consequently, the diameter shape forming rate of the connection portion 7 can be brought to about 100%, and the contact resistance of the connection portion can be improved.

Next, by means of loosening the upper housing 74 from the lower case 73 over the joint 75 the upper portion of the lower housing 73 opened, and it becomes a construction of the intermediate piece 92 and the second spur gears 69 and 70 in the lower case 73 released.

The twisted linear metal object 10 is then passed through the notch section 93 of the intermediate piece 92 released. Thereafter, the non-twisted portions of the end portions 5 and 6 extending from the connecting section 7 extend, cut off by means of a pair of pliers, a clipper or the like. As a result, the end portions become 5 and 6 of the linear metal object 10 twisted together and plastically deformed and so on the connecting portion 7 united that a tight or fixed connection state can be obtained.

Further, without performing annealing after twisting the connection portion 7 using a soft metal of low melting temperature 8th firmly fixed or fastened. Consequently, unwinding of the connecting portion 7 can be suppressed, and further the connection resistance thereof can be improved, whereby a fixed connection state is obtained.

As described above, according to this embodiment, the vicinity of the end portion of the sub wire becomes 4 in the passageways 86 held, the environment of the end portion of the main wire 3 gets through the slots 87 held, the main wire 3 and the side wire 4 are suspended so that the vicinities of the end portions thereof overlap with each other in the axial direction and the second spur gears 69 and 70 are rotated relatively in opposite directions around, between the passage opening 68 and the slot 87 as the center of rotation. Consequently, between the second rotators 69 and 70 if the side wire 4 twisted as if this is around the main wire 3 is screwed, the connection can be easily made or completed, and the main wire 3 and the side wire 4 which are twisted together in this way are firmly connected to each other due to a frictional force generated therebetween. Further, because the connection by simply rotating the second rotators 69 and 70 can be performed, which the through holes 86 and the slots 87 in opposite directions, the connection operation can be easily performed at a low cost.

Furthermore, because the side wire 4 in the state around the main wire 3 in which the main wire is wound 3 and the side wire 4 that between the pair of second rotators 69 and 70 hang, with respect to the movement in the diameter direction are limited to the outside, the main wire 3 and the side wire 4 along the twist axis of rotation can be stably fixed, and while unstable movement and swinging is avoided, the main wire 3 and the side wire 4 be twisted firmly together. In this step, because the main wire 3 near the turning center side, compared to the side wire 4 , arranged, become the main wire 3 and the side wire 4 neither uniform nor evenly overlapped, screwed and twisted together and the connection is made so that the secondary wire 4 around the screwed main wire 3 is wound. Consequently, a reduction in the strength of the connection portion 7 be suppressed. Ie. the main wire 3 acting as a central conduit may be responsible for an anti-traction load and the sub-wire 4 acting as a lateral conduit may be responsible for anti-slip properties.

Further, since the tensile load ratio of the main wire 3 to the secondary wire 4 may be set in the range of 10: 3 to 10: 6, the sub-wire may be 4 more reliable around the screwed main wire 3 be twisted.

Further, by supplying electricity from the heater H between the end portions 5 and 6 of the twisted connection section 7 of the linear metal object 10 the connecting section 7 heated at a temperature of 250 to 500 ° C and maintained for 10 seconds or more for annealing. As a result, the diameter-shape forming rate of the connection portion 7 be brought to about 100% by the simple heater, so that the connection resistance of the connection portion can be improved.

Furthermore, by introducing the main wire 3 in the slots 87 the main wire 3 simply by means of the holder sections coming out of the slots 87 are made to be kept. Further, after the main wire 3 and the side wire 4 interconnected, the linear metal object 10 just from the slots 87 be removed.

Further, since the other holding portions of the through holes 86 are made, if the side wire 4 by passing through the through holes 86 is held, the outer circumference of the sub wire 3 by means of the inner peripheries of through-holes 86 held while the main wire 3 and the side wire 4 Further, twisting can be reliably performed on the connecting portion 7 be performed.

Further, at the connecting portion 7 the main wire 3 and the side wire 4 firmly twisted together by means of a plastic deformation, so that an excellent connection state can be obtained. Furthermore, unwinding of the main wire 3 and the connection wire 4 at the connecting portion 7 can be suppressed, and further, the strength of the connecting portion 7 be improved. Furthermore, without leaving an extra length of the main wire 3 and the side wire 4 be arranged in a connection state.

Further, in the case where the linear metal object 10 is introduced into a path (line) as an intermediate for a subsequent step, a difficulty can be reliably avoided in which the connecting section 7 is separated when the cut end portion 5 hooked somewhere and creates an excessive load that is applied to it.

Further, the main wire becomes 3 in the slots 87 held. Consequently, the main wire can 3 just in the slots 87 and the linear metal object 10 can of the holding sections, which are out of the slots 87 are made to be kept.

Further, since the heater H for heating only the connecting portion 7 is provided while this in the connecting device 60 can be performed, steps that contain the annealing can be performed.

Furthermore, the slots open 87 which are the holding sections which the main wire 3 hold, between teeth, on the outer peripheral sides of the second spur gears 69 and 70 are provided, which with those of the first spur gears 67 and 68 are to be engaged. Consequently, as compared with the case where the slit is formed at the tooth position, the teeth of the second spur gears can 69 and 70 Reliable with those of the first spur gears 67 and 68 can be engaged, and thus a reduction in the tooth life and a transmission defect of the power from the first spur gears 67 and 68 be suppressed.

Furthermore, since the first spur gears 67 and 68 and the driven bevel gears 63 and 64 concentric with each other are associated with an intermediate space, the length of the intermediate piece 92 for twisting the sub wire 4 around the main wire 3 be large, and further, when the number of teeth of the first spur gears 67 and 68 that with the second spur gears 69 and 70 are smaller than those of the driven bevel gears 63 and 64 is set, the twisting torque can be relatively increased. Further, a reduction in the number of components and a simplification of the structure can be achieved, and hence costs can be further reduced.

Further, the connection may be by twisting predetermined lengths of the main wire 3 and the sub wire 4 and further, the twisting can be performed more uniformly.

Further, because the rotational force of the first spur gears 67 and 68 which have a smaller outer diameter than the discs 65 and 66 have, to the second spur gears 69 and 70 , is transmitted, the number of teeth of the first spur gears 67 and 68 and the second spur gears 69 and 70 be set smaller than that of the driven bevel gears 63 and 64 , and by increasing the transmission torque, the twisting torque can be increased.

The above connection method has been described by way of example using the housing in which the main wire 3 and the side wire 4 be connected to each other; however, the connection method can of course also be applied to a housing in which, after a linear metal object 10 is wound to form an annular shape, the end portions 5 and 6 be connected with each other.

Further, as with the first rotators and the second rotators, instead of the first spur gears 67 and 68 and the second spur gears 69 and 70 Also, power transmission means such as spiral wheels or rollers may be used.
