Description

  The present invention relates to a cable used for, for example, a power supply line and various signal lines. More specifically, the present invention relates to a cable in which a cutting position can be easily specified and the remaining length can be easily determined even after cutting.

  For example, various cables such as electric wires and signal wires are generally shipped in a state of being wound on a reel or the like, and used by cutting out a necessary length. In addition to commercial use, these cables may be sold directly to consumers at general retail stores.

  In many cases, retail sales are usually carried out by measuring the cable ordered by the consumer using a measure and cutting it. However, this method is time-consuming and time-consuming because it is sold after measuring the length with a major each time.

  Therefore, for example, a cable as shown in Patent Document 1 is partially provided. As shown in FIG. 4, marks 2 are provided on the surface of the cable 1 at intervals of 1 meter. The mark 2 includes a linearly formed position mark 2a and a length mark 2b in which the length from the tip of the cable 1 to the position mark 2a is described adjacent to the position mark 2a.

  According to this, it is obvious how long the cable has been used so far. Therefore, by reversely using the mark 2 and cutting the cable with the mark 2, the cable can be cut with a certain length without using a ruler or the like.

  However, this type of mark 2 is provided only for determining the length from the tip of the cable 1, and there are the following problems when cutting and selling as described above. That is, in the conventional cable, the starting end of the cable is 0 (zero), and the numbers increase in order of 1 m, 2 m, 3 m,. It is not possible to accurately grasp whether it remains.

  Therefore, when the retailer performs inventory management or inventory, the remaining cable length can only be measured by hand, or it can be calculated by subtracting the length shown as the length mark 2b from the entire cable length. Eventually it took time and effort. Similarly, it was inconvenient because it was not possible to respond immediately to inquiries from consumers.

  Furthermore, since each mark 2 is provided only at one place, if the cable 1 is cut at the left side of the position mark 2a in FIG. When you do, you may be worried about whether you have been cut at a certain position.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cable that can not only easily determine the remaining length but also can be surely cut by a certain amount. It is in.

  In order to achieve the above-described object, the present invention has several features described below. The cable according to claim 1, wherein cutting marks for cutting are provided on the outer surface at regular intervals along the length direction, and each cutting mark has a length direction across the cutting reference point of the cable. Are provided with a predetermined width.

  According to a second aspect of the present invention, the cutting mark includes a pair of cutting auxiliary marks arranged symmetrically with a predetermined width around the cutting reference point.

  According to a third aspect of the present invention, the cutting mark is formed of a single thick line having an equal width centered on the cutting reference point.

  According to a fourth aspect of the present invention, the width of the cutting mark is 1 mm to 10 mm.

  According to a fifth aspect of the present invention, each of the cut marks is further provided with a remaining mark indicating the remaining length from the front end to the end of the cable.

  According to a sixth aspect of the present invention, the remaining amount mark is provided as a pair symmetrically with respect to the cut mark.

  According to the first aspect of the present invention, the cable is cut at the cutting reference point by being provided with a predetermined width symmetrically across the cutting reference point of the cable. A part of the cut mark remains, and it can be easily determined that the cable is reliably cut in the vicinity of the cut reference point.

  According to the second aspect of the present invention, the cutting auxiliary mark is provided by cutting the cable between the cutting auxiliary marks by providing two cutting auxiliary marks so as to sandwich the cutting reference point of the cable. The cutting position can be easily specified while leaving

  According to the third aspect of the present invention, it is possible to easily specify the cutting position by being a single thick line centered on the cutting reference point.

  According to the invention described in claim 4, it is possible to reliably leave the cut marks at both ends of the cut cable. That is, if the width of the cut mark is less than 1 mm, it may be difficult to determine whether or not the cut auxiliary mark remains on the cable when cut. On the contrary, if the width exceeds 10 mm, the cutting reference point is difficult to be determined, and the error of the cutting length becomes large.

  According to the invention described in claim 5 or 6, since the remaining mark is provided in the cut mark, not only can the remaining length of the cable be determined at a glance, but also the Since the remaining amount marks remain at both ends, it can be easily determined whether or not the cutting is performed at the correct position.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view and a partially enlarged view showing a cable according to an embodiment of the present invention. FIG. 2 is an enlarged view of a main part of the cable.

  In the present invention, the cable refers to a wire material in which a core wire such as an electric wire or various signal wires is covered with an outer sheath, and more specifically, various line cables for audio, speaker cables, video cables, various power cables, digital In addition to audio cables and optical cables, various harnesses such as automobiles are included. The basic structure and internal structure of the cable are arbitrary.

  The cable 10 has a core wire (not shown) inside and is a covered cable in which the core wire is covered with an outer cover made of synthetic resin, and is stored in a state of being wound around a reel R. In this embodiment, the cable 10 is wound around the reel R, but it is not necessary to be wound around the reel R and stored.

  On the outer surface of the cable 10, cutting marks 20 for cutting are provided at predetermined intervals L along the length direction in this example at intervals of 1 meter. The display interval of the cut marks 20 may be set as appropriate, such as 50 centimeters or 20 centimeters. In addition to the cutting mark 20 of the present invention, the cable 10 may be printed with various information such as a covering material, a power line capacity, a manufacturing model number, and a product name.

  Although the cutting marks 20 appear at predetermined intervals, as shown in the partial enlarged view of FIG. 1 and FIG. 2, the cutting marks 20 are arranged to face each other with a predetermined width x along the length direction of the cable 10. A pair of auxiliary cutting marks 21 and 22 are included.

  In this example, the width x between each of the auxiliary cutting marks 21 and 22 is 4 mm, but the auxiliary cutting marks 21 and 22 are provided at equal width positions around the cutting reference point P appearing every 1 meter. Is preferred. Further, a third auxiliary mark representing the cutting reference point P may be further provided between the cutting auxiliary marks 21 and 22.

  In this example, the width x of the auxiliary cutting marks 21 and 22 is set to 4 mm, but more preferably 1 mm to 10 mm (more preferably 3 mm to 8 mm). That is, it is not preferable that the width x is less than 1 mm because it is difficult to determine whether or not the cutting assist mark remains when the cable is cut. On the other hand, if the width x exceeds 10 mm, the cutting reference point P is difficult to be determined, and an error may occur in the cutting length.

  Each of the auxiliary cutting marks 21 and 22 is formed by arranging straight lines orthogonal to the length direction of the cable 10 in parallel to each other, but may be a dot shape or a striped pattern, etc. If the auxiliary marks 21 and 22 can be arranged as a pair, the shape thereof is arbitrary.

  Furthermore, the cutting mark 2 only needs to have a predetermined width around the cutting reference point P. For example, as shown in FIG. Good. That is, the cable 10 includes a rectangular cutting mark 20 having a predetermined width x (in this example, the width x is 4 mm) in the length direction. The line width x is also preferably 1 mm or more and 10 mm or less (more preferably 3 mm or more and 8 mm or less).

  According to this, the cutting auxiliary marks 21 and 22 remain at both ends of the cut cable 10 when a part of the thick line is cut, so that it can be determined at a glance whether or not the cable 10 has been cut at an allowable fixed position. Judgment can be made.

  In addition, as shown in FIG. 3B, there is a method in which the cut mark 20 is changed to a thick line and formed into a diamond shape. According to this, the rhombus diagonal can be used as the virtual cutting reference line P, and the cable 10 can be cut at a more accurate position.

  Referring to FIG. 2 again, the cutting mark 20 is provided with remaining amount marks a and a in which the remaining length from the front end 1a to the end of the cable is described. The remaining amount marks a and a are provided adjacent to the respective cutting assisting marks 21 and 22, and the numerical values become smaller toward the end side. In FIG. 2, the remaining amount mark a is arranged on the left side of the cutting assistance mark 21, and the remaining amount mark a is arranged on the right side of the cutting assistance mark 22.

  According to this, the space between the cutting auxiliary marks 21 and 22 (in this example, the remaining 33 meter points) is used as a cutting reference point, and the cable 10 is cut therefrom, whereby the end portion 10a of the cable 10 is Since the cutting auxiliary mark 22 and one remaining mark a remain, not only can the remaining length of the cable 10 be easily determined, but also the cable 10 is cut at a predetermined allowable range by the cutting auxiliary mark 22. You can see that

  Similarly, the cut assisting mark 21 and the other remaining amount mark a remain at the end 10b of the disconnected cable 10 (left side in FIG. 2), so that it is easy to be cut at a predetermined allowable range position. Can be determined. Moreover, since the remaining amount mark a at the time of previous cutting | disconnection remains in the edge part on the opposite side which is not shown in figure, the full length of the cable 10 cut | disconnected from now can be calculated | required.

  In this embodiment, the cutting mark 20 and the remaining amount marks a and a are printed on the surface of the cable 10. For example, the cable 10 and the seal on which the cutting mark 20 and the remaining number marks a and a are described. May be prepared separately, and a seal may be bonded to the cable 10 at a predetermined interval, and these various modifications are also included in the present invention.
