Description

The present invention relates to a tool used for stripping a coated electric wire, and particularly to an electric wire coating stripping tool capable of detecting contact of a blade with a core wire.

Communication-coated wires used in communication wiring boards such as power generation and substations and wireless relay stations have a thin wire diameter of about 0.5 mm. Nippers and a special peeler are used to peel off the coating of the communication coated wire, but the wire diameter is small and the lead wire (core wire) is easily damaged. Since there is a risk of disconnection of the covered wire for communication with a damaged core wire, after peeling off the coating, it is visually checked prior to laying, etc., but such work is very time-consuming.

The core wire is damaged when the coating of the coated wire is peeled off, and the problem is also pointed out in the conductor opening where the coating is peeled off after cutting the coated wire wound around the bobbin to a fixed length (for example). See Patent Document 1). In order to solve such a problem, in the conductor mouthing method of the coated electric wire wound around the bobbin, a coating stripping method and an apparatus capable of detecting whether or not the blade used for coating stripping has come into contact with the core wire have been developed. (See, for example, Patent Documents 1, 2 and 3).

In the method of squeezing a covered electric wire described in Patent Document 1, one end of the connecting electric wire is connected to the winding start end of the bobbin and the other end is connected to the cutter via an energization detector, and the cutter contacts the core wire when the coating is peeled off. Then, it is notified via the energization detector. In the core wire scratch detection device described in Patent Document 2, when a coated electric wire is inserted through the detection head and an AC voltage is applied to the mouthpiece cutter, a current flows between the covered wire and the detection head when the mouthpiece cutter comes into contact with the core wire. Based on this, it is detected that the mouth cutter has come into contact with the core wire.

The core wire contact detection device described in Patent Document 3 detects the vibration generated by the contact between the core wire and the strip blade, and detects the contact between the core wire and the strip blade from the detected vibration amplitude.

Since the method of squeezing the covered electric wire and the core wire contact detection device described in Patent Documents 1 to 3 are intended for squeezing the coated electric wire wound around the bobbin, they are applied to the coated electric wire that has already been wired. It's difficult. Further, the core wire contact detection device used in Patent Documents 1 to 3 is a stationary device, and it is structurally difficult to apply the technique used here to a handy type peeler or the like.

An object of the present invention is to provide an electric wire coating stripping tool that has a simple structure and is easy to use, and detects and notifies contact of a blade with a core wire.

The present invention includes a coating stripping tool main body provided with a pair of blades that bite into the coating of a coated electric wire, and a notification means for detecting and notifying when continuity occurs between the pair of blades. The wire coating stripping tool is characterized in that when both of them come into contact with the core wire of the coated electric wire, the notification means notifies the core wire.

In the electric wire coating stripping tool of the present invention, the alarm means includes an alarm and a battery for supplying power to the alarm, and the alarm and the battery are mounted on the coating stripping tool main body. And.

Further, in the electric wire coating stripping tool of the present invention, the pair of blades are attached to the coating stripping tool main body in a state of being electrically insulated from each other.

Further, in the electric wire coating stripping tool of the present invention, the coating stripping tool main body has a pair of handles whose tips are connected to each other so as to be openable and closable, and the pair of blades are provided at the tips of the handles. It is characterized by being.

Further, the electric wire coating stripping tool of the present invention is characterized by being a handy type.

Further, in the electric wire coating stripping tool of the present invention, the coating stripping tool main body is a stapler type peeler, a nipper, or a wire stripper.

FIG. 1 is an external view of the electric wire coating peeling tool 1 according to the first embodiment of the present invention, FIG. 2 is a configuration diagram of a notification means 55 of the electric wire coating peeling tool 1, and FIG. 3 is a usage state of the electric wire coating peeling tool 1. It is a figure which shows.

The electric wire coating stripping tool 1 of the first embodiment of the present invention is a tool used when peeling the covering material 103 of the coated electric wire 101, and includes a coating stripping tool main body 11 for peeling the covering material 103 of the coated electric wire 101. It includes a notification means 55 that is mounted on the coating stripping tool main body 11 and detects and notifies when the blade of the coating stripping tool comes into contact with the core wire 105.

The coating stripping tool main body 11 has a pair of handles 12a and 12b whose end portions are rotatably connected to each other via a connecting pin 13 and whose tip portions can be opened and closed. A torsion spring (not shown) is attached to the end portions of the pair of handles 12a and 12b so as to be inserted into the connecting pin 13, and the torsion spring is urged so that the tips of the pair of handles 12a and 12b open. ..

Blades (blades) 15a and 15b that bite into the covering material 103 are attached to the tips of the pair of handles 12a and 12b so as to be orthogonal to the longitudinal direction of the handles 12a and 12b, respectively. The distances of the blade body 15a and the blade body 15b from the connecting pin 13 are equidistant. Further, the tip portion of the handle 12a is provided with a stopper 16 for holding the blade body 15a and the blade body 15b at a predetermined interval when the handles 12a and 12b are closed. Therefore, even if the pair of handles 12a and 12b are completely closed, the blade body 15a and the blade body 15b do not come into direct contact with each other. However, the wire coating stripping tool of the present invention does not have to be provided with the stopper 16.

The blade body 15a is attached to the handle 12a, and the blade body 15b is attached to the handle 12b in a state of being electrically insulated. The handles 12a and 12b and the blades 15a and 15b are all made of a conductive metal material, and the blades 15a are fixed with an insulating plate 17a interposed between the handles 12a and 12b and the blades 15a and 15b. The blade body 15b is also fixed by interposing an insulating plate member 17b between the blade body 15b and the handle 12b. Further, an insulating plate member 19 is interposed between the blade body 15a and the stopper 16.

Ensuring the electrical insulation between the blade body 15a and the handle 12a, and the blade body 15b and the handle 12b is not limited to the above embodiment. Normally, metal materials are often used for the blades 15a and 15b from the viewpoint of sharpness and wear, but the handles 12a and 12b are plastic materials, or the handles 12a and 12b are coated with a synthetic resin material on the surface of the metal material. In such a case, even if the blade body 15a is directly attached to the handle 12a and the blade body 15b is directly attached to the handle 12b, electrical insulation is ensured.

Further, the coating stripping tool main body 11 of the present embodiment includes a distance adjusting plate 18 slidably attached to the handle 12a. The distance adjusting plate 18 is a member for adjusting the length of the covering material 103 to be peeled off, and the distance between the blade 15a and the distance adjusting plate 18 is the length of the covering material 103 to be peeled off. However, the distance adjusting plate 18 may not be provided in the electric wire coating stripping tool of the present invention.

The coating stripping tool body 11 is similar to a known peeler except that the blade 15a is attached to the handle 12a and the blade 15b is electrically insulated from the handle 12b. It is a composition.

The notification means 55 is a means for detecting and notifying when the blades 15a and 15b come into contact with the core wire 105 when the covering material 103 is peeled from the coated electric wire 101, and the light emitting element 56 and the light emitting element 56 which are notification devices (notifiers). It includes a sounding element 57 and a battery 58 that supplies power to the light emitting element 56 and the like. As shown in FIG. 2, the blade body 15a, the battery 58, the switch 59 for opening and closing the circuit, the sounding element 57, the light emitting element 56, and the blade body 15b are connected via electric wires 60, 61, 62 to inform the circuit. Is formed.

The light emitting element 56, the sounding element 57, the battery 58, and the like are not particularly limited, and an LED lamp can be used for the light emitting element 56, a buzzer can be used for the sounding element 57, and a button battery or the like can be used for the battery 58. The light emitting element 56 is attached to the tip end side of the upper surface of the handle 12b, and the sounding element 57 is attached to the end end side of the upper surface of the handle 12b. The mounting positions of the light emitting element 56 and the sounding element 57 are not limited to the positions of the present embodiment, but are positions that do not interfere with the use, and the light emitting element 56 is easy to see when lit. The position is good.

The battery 58 is fixed to the back surface of the handle 12b, and the switch 59 is fixed to the side surface of the handle 12b. The positions are not particularly limited as long as they do not interfere with the operation. If the notification circuit is not closed by the stopper 16 even if the handles 12a and 12b are closed as in the coating stripping tool main body 11 of the present embodiment, the switch 59 may be omitted.

In the notification means 55 including the above, the notification circuit is not closed even if the handles 12a and 12b are closed due to the presence of the stopper 16, but a conductive member such as a core wire 105 is interposed between the blade 15a and the blade 15b. When the blade body 15a and the blade body 15b are brought into contact with each other, the notification circuit is closed, the light emitting element 56 is turned on, and the sounding element 57 sounds. The notification circuit is not limited to the present embodiment as long as it can notify the conduction between the blade body 15a and the blade body 15b via a notification device such as a light emitting element 56.

A method of using the electric wire coating stripping tool 1 will be described. Prior to peeling of the covering material 103 of the covered electric wire 101, it is confirmed that the battery 58 is consumed, the notification circuit is disconnected, and the like. Specifically, with the switch 59 turned on, the core wire 105 of the coated electric wire 101 or another conductive member is sandwiched between the blade body 15a and the blade body 15b, the light emitting element 56 lights up, and the sounding element 57 rings. Make sure you do. If the light emitting element 56 does not light up and the sounding element 57 does not ring at this point, the battery 58 is suspected to be dead.

The covering material 103 of the coated electric wire 101 is peeled off as follows. As shown in FIG. 3, the electric wire coating stripping tool 1 is grasped with one hand 111, the coated electric wire 101 is inserted between the blades 15a and 15b with the handles 12a and 12b open, and the distance of the tip of the coated electric wire 101 is adjusted. It is brought into contact with the plate 18. Next, the handles 12a and 12b are closed, the blades 15a and 15b are made to bite into the covering material 103, and in that state, the coated electric wire 101 and the electric wire coating peeling tool 1 are separated to remove the covering material 103.

If the covering material 103 can be peeled off without bringing the blades 15a and 15b into contact with the core wire 105, the light emitting element 56 will light up and the sounding element 57 will not ring. On the other hand, when the light emitting element 56 lights up and the sounding element 57 rings, it means that both the blade body 15a and the blade body 15b are in contact with the core wire 105.

The blades 15a and 15b come into contact with the core wire 105 not only when the blades 15a and 15b bite into the covering material 103, but after that, the covered electric wire 101 and the electric wire coating stripping tool 1 are separated and coated. It can also occur when removing the material 103. In either case, if the blade body 15a and the blade body 15b come into contact with the core wire 105, the core wire 105 may be scratched. Therefore, it is preferable to cut this portion and peel off the new portion again.

In the wire coating stripping tool 1, when only one of the blade 15a and the blade 15b contacts the core wire 105 and the other does not contact the core wire 105, the notification circuit is not closed and the light emitting element 56 is not lit. , The sounding element 57 also does not sound. However, due to the structure of the coating stripping tool body 11, it is difficult to imagine a state in which only one of the blade 15a and the blade 15b is in contact with the core wire 105 and the other is not in contact with the core wire 105. It is difficult to peel off 103. Therefore, when the light emitting element 56 does not light up and the covering material 103 can be peeled off without the sounding element 57 ringing, it can be determined that neither the blade body 15a nor the blade body 15b is in contact with the core wire 105.

As described above, the electric wire coating stripping tool 1 of the first embodiment is a handy type tool, and the notification means 55 for detecting and notifying the contact of the blades 15a and 15b with the core wire 105 is also attached to the coating stripping tool main body 11. Because it is made, it can be used easily. When the blades 15a and 15b come into contact with the core wire 105, the notification means 55 detects and notifies the core wire 105. In other words, it can be said that the fact that the alarm does not operate ensures that the blades 15a and 15b are not in contact with the core wire 105, and it is easy to use, such as eliminating the need for visual inspection after peeling the covering material 103. Excellent.

FIG. 4A is an external view of the electric wire coating peeling tool 2 according to the second embodiment of the present invention, and FIG. 4B is a diagram for explaining the structure of the connecting portion of the electric wire coating peeling tool 2. FIG. 5 is a circuit diagram of the notification means 55 of the wire coating stripping tool 2, and FIG. 6 is a diagram showing a usage state of the wire coating stripping tool 2. The same configurations as those of the electric wire coating stripping tool 1 of the first embodiment shown in FIGS. 1 to 3 are designated by the same reference numerals, and the description thereof will be omitted.

The basic configuration of the electric wire coating stripping tool 2 is the same as that of the electric wire coating stripping tool 1 of the first embodiment, and is attached to the coating stripping tool main body 21 for peeling the covering material 103 of the coated electric wire 101 and the coating stripping tool main body 21. It includes a notification means 55 that detects and notifies when the blade of the coating stripping tool main body 21 comes into contact with the core wire 105.

The coating stripping tool main body 21 has substantially the same shape and structure as the nippers, and the blades 26a and 26b are provided on the tip portions 23a and 23b, and the connecting portions 24a and 24b and the grip portions 25a and 25b following the tip portions 23a and 23b are provided. A pair of handles 22a and 22b are rotatably connected to each other. The connecting portions 24a and 24b have a hinge structure, and the grip portions 25a and 25b and the tip portions 23a and 23b are rotatably configured around the connecting portions 24a and 24b, and the grip portions 25a and 25b are closed. The blade 26a and the blade 26b can be brought into contact with each other.

The connecting portion 24a of the handle 22a includes a disk 27a having a thickness half that of the grip portion 25a connected to the grip portion 25a, and a rotating pin 31 is erected at the center of the back surface of the disk 27a. The connecting portion 24b of the handle 22b includes a disk 27b having a thickness half that of the grip portion 25b connected to the grip portion 25b, and has a fitting hole 32 in the center of the disk 27b into which the rotating pin 31 is fitted.

The two connecting portions 24a and 24b are hinged by rotatably fitting the rotating pin 31 into the fitting hole 32. At this time, a cylindrical member 33 having electrical insulation is interposed between the fitting hole 32 and the rotating pin 31, and further, between the disc 27a and the disc 27b, and between the disc 27a and the tip portion 23b. A plate member 34 having electrical insulation is interposed between the disk 27b and the tip portion 23a.

The handles 22a and 22b are both made of a metal material as a whole, but the two handles 22a and 22b are electrically insulated by connecting the handles 22a and 22b with a member having electrical insulation as described above. Can be connected in a state of being. A covering material 35 having electrical insulation is also attached to the grip portions 25a and 25b.

What is important here is that the two blades 26a and 26b are electrically insulated from each other in a non-contact state, and the two blades 26a and 26b are electrically insulated from each other in a non-contact state. It is not limited to the above embodiment as long as it is in the above-mentioned state. For example, if the two tip portions 23a and 23b are made of a metal material and the connecting portions 24a and 24b are made of a plastic material, the two blades 26a and 26b can be in a non-contact state and electrically insulated from each other. ..

The coating stripping tool main body 21 has the same configuration as known nippers, except that the tip portions 23a and 23b including the blades 26a and 26b are configured to be electrically insulated from each other in a non-contact state. Is.

The notification means 55 that detects and notifies when the blades 26a and 26b come into contact with the core wire 105 when the covering material 103 is peeled from the coated electric wire 101 has the same configuration as that of the first embodiment, and is as shown in FIG. The same applies to the notification circuit.

In the electric wire coating peeling tool 2, the switch 59, the sounding element 57, and the light emitting element 56 are fixed to the upper surface of the connecting portion 24a in a laminated state. The battery 58 is built in the switch 59. The sounding element 57 and the light emitting element 56 are detachably attached to the switch 59 so that the battery 58 can be easily replaced.

The tip 23a is connected to one end of the battery 58 via the electric wire 60, and the tip 23b is connected to one end of the light emitting element 56 via the wire 61. The battery 58, the switch 59, the sounding element 57, and the light emitting element 56 are connected by an electric wire 62 (see FIG. 5). The electric wire 60 is attached so as to crawl on the upper surface of the tip portion 23a and is covered with a cover 36. Similarly, the electric wire 61 is attached so as to crawl on the upper surface of the tip portion 23b and is covered with the cover 37. The electric wires 60, 61, 62 and the covers 36, 37 are attached so as not to interfere with the opening and closing of the tip portions 23a, 23b.

When the handles 22a and 22b are closed, the blades 26a and 26b come into contact with the notification means 55, the notification circuit is closed, the light emitting element 56 is lit, and the sounding element 57 sounds.

A method of using the electric wire coating peeling tool 2 will be described. Prior to peeling of the covering material 103 of the covered electric wire 101, it is confirmed that the battery 58 is consumed, the notification circuit is disconnected, and the like. Specifically, with the switch 59 turned on, the handles 22a and 22b are closed and the blade 26a and the blade 26b are brought into contact with each other, and it is confirmed that the light emitting element 56 lights up and the sounding element 57 sounds. If the light emitting element 56 does not light up and the sounding element 57 does not ring at this point, the battery 58 is suspected to be dead.

The peeling of the covering material 103 of the coated electric wire 101 is the same as that of a normal nipper. The handles 22a and 22b are closed, the blades 26a and 26b are made to bite into the coated electric wire 101, and in that state, the coated electric wire 101 and the electric wire coating peeling tool 2 are separated to remove the covering material 103.

At this time, if the light emitting element 56 lights up and the sounding element 57 does not ring, it means that the covering material 103 could be peeled off without bringing the blades 26a and 26b into contact with the core wire 105. On the other hand, when the light emitting element 56 lights up and the sounding element 57 rings, it means that both the blade 26a and the blade 26b are in contact with the core wire 105.

The blades 26a and 26b come into contact with the core wire 105 not only when the blades 26a and 26b bite into the covering material 103, but after that, the covered electric wire 101 and the electric wire coating peeling tool 2 are separated to separate the covering material 103. It can also happen when removing. In either case, if the blade 26a and the blade 26b come into contact with the core wire 105, the core wire 105 may be scratched. Therefore, it is preferable to cut this portion and peel off the new portion again. This point is the same as that of the electric wire coating stripping tool 1 of the first embodiment.

In the electric wire coating peeling tool 2, even if only one of the blades 26a and 26b comes into contact with the core wire 105, the light emitting element 56 does not light up and the sounding element 57 does not ring, as in the electric wire coating peeling tool 1. On the other hand, judging from the structure of the coating stripping tool main body 21, it is difficult to assume that only one of the blade 26a and the blade 26b is in contact with the core wire 105 and the other is not in contact with the core wire 105. It is difficult to peel off the covering material 103. Therefore, when the covering material 103 can be peeled off without the light emitting element 56 lighting and the sounding element 57 not ringing, it can be determined that neither the blade 26a nor the blade 26b is in contact with the core wire 105. This point can be considered in the same manner as the electric wire coating stripping tool 1.

FIG. 7 is an external view of the wire coating stripping tool 3 according to the third embodiment of the present invention, and FIG. 8 is a diagram showing a usage state of the wire coating stripping tool 3. The same configurations as the electric wire coating peeling tool 1 of the first embodiment shown in FIGS. 1 to 3 and the electric wire coating peeling tool 2 of the second embodiment shown in FIGS. 4 to 6 are designated by the same reference numerals. Is omitted.

The basic configuration of the wire coating stripping tool 3 is the same as that of the wire coating stripping tools 1 and 2, and the coating stripping tool main body 41 for peeling the covering material 103 of the coated electric wire 101 and the coating stripping tool main body 41 attached to the coating stripping tool main body 41 are attached. It includes a notification means 55 that detects and notifies when the blade of the main body 41 comes into contact with the core wire 105.

The coating stripping tool main body 41 has substantially the same shape and structure as a wire stripper, which is a tool for stripping the coating material 103 of the coated electric wire 101, and has seven round hole shapes having different diameters to correspond to the wire diameter of the coated electric wire 101. Blades 46 (46a, 46b) are provided. The tip portion 43a of the handle 42a is provided with a groove 49a that is inclined from the surface (front surface) 47a of the tip portion 43a toward the back surface of the tip portion 43a, and the edge portion of the groove 49a is a blade 46a. .. The blade 46b is also formed in the same manner as the blade 46a.

The handle 42a and the handle 42b are rotatably and electrically insulated from each other via connecting portions 44a and 44b of a hinge structure located at the center thereof, respectively. A spring 53 that urges the tip portions 43a and 43b to open is attached between the grip portion 45a of the handle 42a and the grip portion 45b of the handle 42b.

The hinge structure is formed as follows. Each connecting portion 44a and connecting portion 44b is provided with a through hole (not shown) through which the connecting pin 51 is inserted, and the handles 42a and 42b are formed by connecting the connecting portion 44a of the handle 42a and the connecting portion 44b of the handle 42b. And are overlapped with each other, and the connecting pin 51 is inserted into the through hole to be connected.

Both the handles 42a and 42b, including the blades 46a and 46b, are entirely made of a metal material, but electrical insulation is ensured as follows. A cylindrical member having electrical insulation (not shown) is inserted through the connecting pin 51 that connects the connecting portions 44a and 44b, and the insulating property between the connecting pin 51 and the through hole (not shown) is ensured. Further, the handle 42b extends from the tip portion 43b to the connecting portion 44b, and the back surface 48b is coated with an electrically insulating coating 52. Similarly, the handle 42a extends from the tip portion 43a to the connecting portion 44a, and the back surface is coated with an electrically insulating coating 52. Here, the back surface refers to the surface of the connecting portions 44a and 44b on the side of contact. The coating 52 is indicated by dots in FIGS. 7 and 8.

A covering material 35 having electrical insulation is attached to the grip portions 45a and 45b, and the mounting seats 54a and 54b provided on the grip portions 45a and 45b to which the spring 53 is mounted are also electrically insulating. The coating 52 is applied.

When the grips 45a and 45b of the handles 42a and 42b of the coating stripping tool main body 41 as described above are closed, the tip portions 43a and 43b rotate from the connecting portions 44a and 44b so as to close, and the blades 46a and 46b are provided. The end portions 50a and 50b of the tip portions 43a and 43b are partially overlapped to form a round hole-shaped blade (see FIG. 8).

What is important here is that when the handles 42a and 42b are completely closed, the ends 50a and 50b of the tips 43a and 43b partially overlap each other, and at this time, there is electrical insulation between the blades 46a and 46b. It is secured. In the present embodiment, as described above, since the back surfaces of the tips 43a and 43b of the handles 42a and 42b are each coated with an electrically insulating coating 52, the electrical between the blades 46a and 46b is electrically formed. Insulation is ensured. However, ensuring the electrical insulation between the blades 46a and 46b is not limited to this embodiment.

The coating stripping tool main body 41 is a known wire stripper except that electrical insulation is ensured between the blades 46a and 46b even when the handles 42a and 42b are completely closed. It has a similar configuration.

The configuration of the notification means 55 that detects and notifies when the blades 46a and 46b come into contact with the core wire 105 when the covering material 103 is peeled from the coated electric wire 101, and the procedure for attaching the notification means 55 to the coating stripping tool main body 41. Since it is the same as the electric wire coating stripping tool 2 of the second embodiment, only the key points will be described.

The electric wire 60 connecting the tip 43a and the battery 58 is on the surface (front surface) 47a of the tip 43a, and the electric wire 61 connecting the tip 43b and the light emitting element 56 is on the surface (front surface) of the tip 43b. It is attached so as to crawl on the surface) and is covered with covers 36 and 37, respectively. Since the light emitting element 56 and the like are mounted on the connecting pin 51 on the surface (front surface) of the connecting portion 44a, the electric wire 61 and the cover 37 have the surface (front surface) of the tip portion 43b. ), It is attached so as to wrap around the surface (front surface) of the connecting portion 44a.
