JP5759870B2 - Electric wire terminal positioning jig and electric wire terminal processing method using the same - Google Patents

Description

  The present invention relates to an electric wire terminal positioning jig for allowing an operator to detect the tip position of an electric wire in an electric wire terminal processing step and an electric wire terminal processing method using the same.

  Conventionally, various positioning means have been proposed for positioning the end (tip) of the electric wire.

  For example, in Patent Document 1 (not shown), the tip of the electric wire is cut (trimmed) in a radial direction with a pair of upper and lower cutters while the electric wire is held by a clamp, and the tip of the cut electric wire is imaged. It describes that it is determined whether or not the distance (cutting length) from the tip of the cut electric wire to the clamp is a specified value by taking an image with a sensor and processing the imaged data.

  The electric wire determined to have a cut length of OK is held by the clamp, the terminal insulation coating is peeled off to expose the core portion, and sent to the terminal crimping device in the next step. The insulation coating is peeled by cutting the insulation coating in the radial direction with a pair of upper and lower V-shaped blades, and then moving the insulation coating in the direction of the electric wire tip together with the insulating coating cutting portion in a state where the pair of blades are closed.

  As other wire end positioning means, the end of the wire is abutted against an electrical stroke sensor and the position of the end of the wire is detected by the amount of displacement of the stroke sensor, or the end of the wire is between a pair of optical sensors. It is known that the position of the tip of the electric wire is detected by the amount by which the tip of the electric wire blocks the light.

Japanese Patent Laying-Open No. 2005-80393 (FIGS. 12 to 15)

  However, each of the conventional wire terminal positioning means described above requires a power source and wiring for operating the image sensor, the stroke sensor, and the optical sensor. For example, the use of the wire terminal positioning means overseas (in Japan) The voltage and the like change outside), and there are problems that it is not suitable for use in the electric wire terminal positioning means for the purpose of energy saving, and that the tuning of the sensor is troublesome.

  In view of the above points, the present invention eliminates the need for troublesome operations such as power supply, wiring, and tuning, can be used in foreign countries where the usage environment such as voltage is different, and can also be used to save energy. An object is to provide a tool and an electric wire terminal processing method using the tool.

  In order to achieve the above object, an electric wire terminal positioning jig according to claim 1 of the present invention is provided with a substrate portion that runs along the longitudinal direction of the electric wire, and is rotatably supported on the substrate portion side. A stopper plate that abuts the tip and a visual plate on the fixed side that enters the hole of the stopper plate rotated in the electric wire abutting direction, and the visual plate rotates in the electric wire abutting direction of the stopper plate It has the marking part for visual confirmation exposed from this hole part according to an angle, It is characterized by the above-mentioned.

  With the above configuration, the electric wire is supplied (sent) toward the stopper plate while being in sliding contact with the substrate portion, the tip of the electric wire comes into contact with the stopper plate, the stopper plate is rotated in the electric wire feeding direction, and the stopper plate The tip of the viewing plate on the fixed side (fixed on the substrate side) is inserted into the hole of the plate, and the marking formed on the tip protrudes from the hole of the stopper plate in the direction opposite to the stopper plate rotation (exposed) ) The operator visually recognizes the color of the marking portion and recognizes whether or not the tip of the electric wire is completely (normally) abutted against the stopper plate.

  For example, if the color of the marking part is arranged side by side in the protruding direction of the visual plate, the visual plate will be used when the tip of the electric wire contacts the stopper plate incompletely (when the electric wire feed is insufficient). The second color of the visual plate when the color of the protruding tip side (NG indication) is recognized by the operator and the tip of the wire is completely in contact with the stopper plate (when the wire feed is sufficient) (OK display) is recognized by the operator. It is also possible to omit the color of NG display and arrange only the color of OK display (one or more marking portions are provided). If the tip of the electric wire is separated from the stopper plate along the substrate portion, the stopper plate is rotated in the electric wire separation direction by an urging means such as its own weight and returned to the initial position.

  An electric wire terminal positioning jig according to a second aspect is the electric wire terminal positioning jig according to the first aspect, wherein the stopper plate is urged by an elastic member in a direction opposite to the electric wire abutment.

  With the above configuration, when the tip of the electric wire is separated from the stopper plate along the board portion from the state where the tip of the electric wire is abutted against the stopper plate, the stopper plate is moved in the electric wire separation direction (electric wire) by the urging force of the elastic member (biasing means). It rotates reliably in the direction opposite to the abutment) and returns to the initial position. For example, the initial position of the stopper plate is regulated by a stopper portion such as a stopper member, and the stopper plate abuts against the stopper portion by the urging force of the elastic member to prevent further rotation in the wire separation direction.

  An electric wire terminal positioning jig according to claim 3 is the electric wire terminal positioning jig according to claim 1 or 2, wherein an electric wire guide cover for covering and inserting the electric wire is provided on the substrate portion over the stopper plate. Features.

  With the above configuration, the electric wire is smoothly and reliably sent by the operator along the electric wire guide cover (along the space surrounded by the electric wire guide cover and the substrate portion) straight to the stopper plate and without being caught.

  According to a fourth aspect of the present invention, there is provided a method for processing an end of an electric wire using the electric wire end positioning jig according to any one of the first to third aspects, in a state where the tip of the electric wire is normally abutted against the stopper plate. The terminal processing is performed.

  With the above configuration, the end of the electric wire is processed in a state where the end of the electric wire is abutted against the stopper plate and the position of the end of the electric wire is properly positioned (a state in which the OK display of the marking portion is confirmed). The end processing of the electric wire is, for example, a process in which the insulating coating of the electric wire is cut in the longitudinal direction of the electric wire with a cutter, or the insulating coating of the electric wire is cut in the circumferential direction of the electric wire with another cutter, and the insulating coating is peeled off. is there. Since the tip of the electric wire is abutted against the stopper plate and accurately positioned, the length of the wire in the longitudinal direction of the insulation coating and the position from the wire tip to the circumferential cut are accurately defined.

  According to the first aspect of the invention, the stopper plate is rotated by the abutting operation of the tip of the electric wire by the operator, and the marking portion of the visual plate is visually observed by the operator to detect the tip position of the electric wire. In addition, troublesome work such as tuning is not required without using a power source and wiring, and it can be used even in foreign countries where the usage environment such as voltage is different, and energy saving can be dealt with.

  According to the invention described in claim 2, when the tip of the electric wire is detached from the stopper plate, the stopper plate can be reliably returned to the initial position.

  According to the third aspect of the present invention, the electric wire can be inserted straight into the space surrounded by the electric wire guide cover and the substrate portion, and the electric wire can be sent straight and smoothly and surely toward the stopper plate. The positioning of the tip of the electric wire can be performed smoothly and reliably.

  According to the fourth aspect of the invention, in the state where the tip of the electric wire is positioned, for example, the length of the longitudinal incision of the insulating coating and the position of the circumferential incision in the end processing of the electric wire (peeling of the insulating coating) are accurately determined. Can be specified.

The vertical flange 5a of the substantially horizontal L-shaped viewing plate 5 is fixed to the upper part of the front surface of the vertical main body 4b of the support plate 4 so that the viewing plate 5 is substantially horizontal (exactly the protruding tip, ie, forward). The main body 5b (slightly downward as it goes) protrudes forward.

  Two-color marking portions (display portions) 12 and 13 for NG display and OK display are formed in parallel at the front and rear at the front end (front end) portion of the main body portion 5b of the viewing plate 5. In this example, the color of the marking portion 12 on the front end side (front side) is red, and the color of the marking portion 13 on the rear side is yellow. The colors of the marking parts 12 and 13 can be set as appropriate (for example, the color of the marking part 13 on the rear side is blue). Since yellow is conspicuous, the visibility of the worker is good.

  It is also possible to omit the front red marking part 12 for NG display and form only the rear OK display yellow marking part 13 (in this case, the operator can use the yellow marking part 13). NG is judged if it is not visible, OK is judged if the yellow marking portion 13 is visible). Moreover, it is also possible to call the viewing plate 5 including the support plate 4 (the support plate 4 is called a support plate portion of the viewing plate 5).

  The front marking portion 12 is formed on a substantially vertical front end surface (front end surface) 12a of the main body portion 5b of the viewing plate 5 and upper, lower, left and right surfaces (outer peripheral surfaces) of the main body portion 5b, and the rear marking portion 13 is visually observed. The main body 5b of the plate 5 is formed in a rectangular ring shape on the upper, lower, left and right surfaces (outer peripheral surfaces).

Also good. The marking parts 12 and 13 are formed wide in the horizontal direction so that they can be seen from a distance by an operator. The visual plate 5, the support plate 4, the substrate unit 3, and the sub plate 11 are made of a metal material.

  A bolt 14 (as a stopper) for abutting against the stopper plate 10 is projected horizontally in the middle in the height direction of the vertical main body 4b of the support plate 4, and the bolt 14 is formed on the support plate main body 4b. The nut 15 penetrates the female screw hole and is fastened and fixed so that the protruding length can be adjusted.

  The stopper plate 10 is formed in a substantially T-shape when viewed from the front as shown in FIG. 2, and includes a vertically long plate portion 10a and a horizontally long plate portion 10b orthogonal to the upper end of the vertically long plate portion 10a. A horizontal slit-shaped hole 9 for inserting (penetrating) the front end portions (marking portions) 12 and 13 of the viewing plate 5 is provided at the center in the longitudinal direction. The horizontally long plate portion 10b is formed to be sufficiently longer in the left-right direction than the slit-shaped hole portion 9, and the marking portion of the visual plate 5 is viewed from obliquely forward with the visual plate 5 of FIG. 12 and 13 cannot be viewed (erroneously detected) by the operator.

  The vertically long plate portion 10a of the stopper plate 10 vertically penetrates the opening 11a inside the U-shaped sub-plate 11 in plan view and the hole portion 8 of the substrate portion 3 so as to form the substrate portion 3 as shown in FIG. It is fixed by bolting or the like to the front side portion in the center in the longitudinal direction of the horizontal shaft portion 7 rotatably supported by a pair of lower left and right bearing blocks 6. The stopper plate 10 can rotate (swing) in the front-rear direction as indicated by an arrow B integrally with the shaft portion 7. The rotation angle of the stopper plate 10 in this example is about 10 °.

  The lower end portion of the vertically long plate portion 10a of the stopper plate 10 is pulled (biased) backward by a tension coil spring (elastic member) 16, and the stopper plate 10 is moved forward by the tension coil spring 16 as shown in FIG. In a state of rotating and being disengaged forward from the viewing plate 5, the forward tilting posture of FIG. 1 is maintained by contacting a stopper portion (not shown). The tension coil spring 16 is for returning the stopper plate 10 to the initial position tilted forward, and the force of the tension coil spring 16 is weak enough not to absorb the abutting force of the electric wire 2 against the stopper plate 10. is there.

  It should be noted that both ends of the shaft portion 7 are not rotatably supported by the pair of left and right bearing blocks 6 but fixedly fixed, and a bearing, a bush or the like fixed to the stopper plate 10 is rotatably fitted to the shaft portion 7. It is also possible to combine them. Further, instead of the tension coil spring 16 on the rear side of the stopper plate 10, a compression coil spring or a leaf spring is arranged on the front side of the stopper plate 10, or instead, a torsion coil spring is arranged around the shaft portion 7. It is also possible. Further, by removing these spring members (elastic members) 16, the stopper plate 10 is returned to the initial position of FIG. 1 by its own weight in the forward tilt direction of the stopper plate 10 that is eccentrically arranged and fixed to the front end of the support shaft 7. Is also possible.

  The front surface of the middle portion in the longitudinal direction of the vertically long plate portion 10 a of the stopper plate 10 acts as a contact surface with respect to the tip surface (tip) 2 a of the electric wire 2. The electric wire 2 is sent (supplied) toward the vertically long plate portion 10a of the stopper plate 10 in a sliding manner along the upper surface of the substrate portion 3 in the electric wire longitudinal direction as shown in FIG.

  As shown in FIG. 2, a horizontal horizontally long (long in the front-rear direction) wire guide cover 17 having an inverted concave cross section is provided on the upper surface of the substrate portion 3, and the wire 2 (FIG. 1) is a wire guide. The guide is smoothly and reliably guided to the stopper plate 10 straight along the inner surface (inner peripheral surface) of the cover 17 and the upper surface of the substrate portion 3.

  The wire guide cover 17 is composed of left and right vertical side walls 17a and upper horizontal wall portions 17b, and distal end portions 17a 'of the left and right side walls 17a are extended on the left and right sides of the vertically long plate portion 10a of the stopper plate 10, The upper wall 17b is cut out in a rectangular shape, and a vertically long plate portion 10a is inserted into the cutout portion 17c. The left and right side walls 17a enter and engage between the left and right plate portions 11b along the left and right plate portions 11b of the U-shaped sub-plate 11 in a plan view.

  As shown in FIG. 2, the substrate unit 3 is fixed to a horizontal base plate 19 of a lower thick plate via a vertical support column 18. The front end of the tension coil spring 16 (FIG. 1) is hooked and fixed in a small hole (not shown) of the stopper plate 10, and the rear end of the tension coil spring 16 is a first not shown that is erected on the upper surface of the base plate 19. It is hooked and fixed on the pin. A horizontal space is disposed between the substrate unit 3 and the base plate 19.

  A stopper plate (not shown) protrudes substantially horizontally on the front surface of the vertically long plate portion 10a of the stopper plate 10 below the substrate portion 3, and a second pin portion (not shown) that abuts the lower surface of the front end of the stopper plate. Standing on the upper surface of the base plate 19, the stopper plate is brought into contact with the second pin portion to maintain the forward inclined posture (angle) of the stopper plate 10.

  Instead of a stopper plate (not shown) and the second pin part, the front end of the hole 8 of the board part 3 or the front end of the notch part 17c of the wire guide cover 17 is used as a stopper part for contacting the stopper plate 10. It is also possible to do. The “stopper plate” means a plate that acts as a stopper for receiving the front end surface 2a of the electric wire 2, and may be called an electric wire abutting plate.

  By moving (sending or supplying) the electric wire 2 backward toward the stopper plate 10 from the state of FIG. 1 as shown by an arrow A, the front end surface (front end) of the electric wire 2 as shown in FIGS. 2a contacts the front surface of the vertically long plate portion 10a of the stopper plate 10, resists the biasing force of the tension coil spring 16, and rotates the stopper plate 10 backward with the shaft portion 7 as a fulcrum. The tip of the rear viewing plate 5, that is, the marking portions 12, 13 enters the slit-shaped hole 9 of the horizontally long plate portion 10 b (the moving-side hole 9 is the marking portion 12 of the stationary viewing plate 5, 13 is extrapolated). The tension coil spring 16 contracts in FIG. 1 and extends in FIG.

  As shown in the enlarged explanatory diagram in the frame line of FIG. 3, when the abutment of the electric wire 2 to the stopper plate 10 is insufficient (the feeding stroke of the electric wire 2 is insufficient), the stopper plate 10 The rearward rotation becomes insufficient, and the red marking portion 12 on the front end side (front side) of the visual plate 5 is located in the slit-like hole portion 9 of the stopper plate 10 and in front of the hole portion 9. Recognizing that the feeding stroke of the electric wire 2 was insufficient by looking at only the red marking portion 12 in a standing state (diagnosis of the yellow marking portion is slightly obliquely downward as shown by arrow C). it can.

  In that case, by pushing the electric wire 2 toward the stopper plate 10 again, the stopper plate 10 is pushed by the front end surface 2a of the electric wire 2 and further rotated backward, and the solid line in the enlarged explanatory diagram in the frame line. As shown, the yellow marking portion 13 following the red marking portion 12 is exposed (projected) forward from the hole portion 9 of the stopper plate 10, and the operator can see the yellow marking portion 13 (the red marking portion 12 and the yellow marking portion 12). The marking portion 13) is visually observed in the direction of arrow C, and it is recognized that the position of the tip 2a of the electric wire 2 has reached the specified (normal) position (that the positioning of the electric wire tip 2a has been accurately performed). be able to.

  In a normal operation, the operator urges the electric wire 2 against the stopper plate 10 along the electric wire guide cover 17 (FIG. 4), so that it is rare that only the red marking portion 12 indicated by NG is exposed. 10 vigorously rotates backward to expose both the red marking portion 12 indicated by NG and the yellow marking portion 13 indicated by OK and the position of the tip 2a of the electric wire 2 reaches the specified position. (The positioning of the wire tip 2a has been accurately performed) is detected.

  In a state where both the front and rear marking portions 12 and 13 protrude from the hole portion 9 of the stopper plate 10, the rear surface of the vertically long plate portion 10 a abuts against the head portion 14 a of the stopper bolt 14, and further stoppers are provided. The rearward rotation of the plate 10 is prevented. The stopper plate 10 is positioned vertically in FIGS. 3 and 4 so as to be in contact (contact) with the entire surface of the vertical tip end surface 2 a of the electric wire 2. The front-rear direction position of the head 14a of the stopper bolt 14 can be adjusted. Instead of the stopper bolt 14, for example, a short vertical flange (not shown) for a stopper that abuts the rear surface of the horizontally long plate portion 10 b of the stopper plate 10 on the horizontal main body portion 5 b of the viewing plate 5. It is also possible to provide it.

  The main body portion 5b including the marking portions 12 and 13 of the visual plate 5 enters smoothly into the hole portion 9 without being caught along the rotation locus of the hole portion 9 of the stopper plate 10 with the support shaft 7 as a fulcrum. It is inclined slightly downward from the horizontal.

  In a state where the position of the tip 2a of the electric wire 2 is defined as shown in FIG. 3, for example, by performing an operation of cutting the longitudinal direction of the electric wire with an unillustrated cutter into an insulating coating (sheath) 2b on the outer peripheral side of the electric wire 2 The length of the cut in the longitudinal direction (from the distal end 2a of the electric wire 2 to the longitudinal intermediate portion) is accurately defined. Alternatively, in the state where the position of the tip 2a of the electric wire 2 is defined as shown in FIG. 3, it is possible to make a circumferential cut in the insulating coating (sheath) 2b on the outer peripheral side of the electric wire 2. In this case, the electric wire 2 The length from the tip 2a to the circumferential cut is accurately defined. For example, after those operations, by pulling the electric wire 2 forward from the state of FIG. 3, the stopper plate 10 is rotated forward by the force of the tension coil spring 16 and restored to the initial position of FIG.

  FIG. 5 shows one form of the electric wire used. This electric wire 2 has an oval cross section in which the outer side of two small-diameter electric wires 20 is wound with a braid 21 made of conductive metal for shielding, and the outer side of the braid 21 is wound with an insulating coating (sheath) 2b made of synthetic resin. It is a high-voltage two-core wire. The two small-diameter electric wires 20 are composed of a large number of conductive strands 20a and an insulating coating 20b made of synthetic resin that covers the outside of the numerous strands 20a.

In the wire guide cover 17 of FIG. 2, the width of the upper wall 17b is set longer than the height of the left and right side walls 17a in accordance with the cross-sectional shape of the high-voltage two-core electric wire 1. When a single-core electric wire (not shown) having a circular cross section is used, the width of the upper wall 17b of the wire guide cover 17 in FIG. 2 is set to be equal to the height of the left and right side walls 17a.

  FIG. 6 shows an embodiment of a wire end processing jig 22 including the wire end positioning jig 1 of FIGS. 1 to 4 and a wire end processing method using the wire end positioning jig 1.

A substantially inverted C-shaped wire guide wall 23 is disposed in the rear half 3 ′ of the extended substrate portion 3, and a wire clamp 24 is fixedly provided on the front upper surface 19 ′ of the extended base plate 19. Is.

  The electric wire guide wall 23 has a pair of left and right tapered walls (substitute with reference numeral 23) that open outward as it goes upward, and a groove 25 between the pair of tapered walls 23. Reference numeral 25 denotes a space inside the wire guide cover 17 through a rectangular opening 26 a of a reverse concave-shaped partition wall 26 between the wire guide wall 23 and the wire guide cover 17. The electric wire clamp 24 has a horizontal electric wire insertion groove 28 between the left and right gripping blocks 27 on the extension of the board portion 3 ′, and the right and left grips while the width of the electric wire insertion groove 28 is reduced by pulling up the lever 29. The electric wire 2 is clamped in the radial direction by the block 27.

  For example, the operator inserts the distal end portion of the high-voltage two-core electric wire 2 of FIG. 5 (substitute with reference numeral 2b ′) into the inner side of the electric wire guide cover 17 while guiding it along the electric wire guide wall 23, 2a (consisting of the tip of the outer insulation coating 2b, the tip of the braid 21, the tip of the insulation coating 20b of the small-diameter electric wire 20 and the tip of the core portion 20c) is abutted against the stopper plate 10 of the wire terminal positioning jig 1. 1 to 4, the marking portions 12 and 13 of the visual plate 5 are visually observed to confirm the positioning OK, and then the electric wire 2 is held and fixed by the electric wire clamp 24.

  As an example, in a state where the electric wire 2 is held and fixed by the electric wire clamp 24, a cutter (not shown) is abutted against the outermost insulating coating (sheath) 2b of the electric wire 2 in FIG. Is pulled forward to cut the insulating coating 2b in the longitudinal direction of the electric wire to make a straight cut in the insulating coating 2b. Alternatively, in the state where the electric wire 2 is held and fixed by the electric wire clamp 24, the outermost insulating coating (sheath) 2b of the electric wire 2 is cut in the circumferential direction with a pair of cutters (not shown) to make an annular cut in the insulating coating 2b. . These cutters and the pair of cutters are arranged using a jig or the like that accurately positions the electric wires 2 in the electric wire radial direction. A cutter for cutting in the longitudinal direction may be provided inside the wire clamp 24. Since the cutting of the insulating coating 2b is proposed separately, the description thereof is omitted in this specification.
