[Problem that the idea aims to solve]

Among the above-mentioned conventional means, the cable cores 3 are colored differently depending on the number of cable cores 3. Insulating material must be prepared. In addition, when changing the color of the insulator 2 of the ground color, the color Clean the inside of the extrusion coating machine and replace extrusion parts each time to prevent mixing. It takes time to change colors, poor productivity, and poor insulation. There is also a lot of wasted material. Although the above method somewhat reduces the time loss when changing the coloring, There are almost the same difficulties as the case. Since the above means displays the number 7, the number of cable cores 3 is large. A different number can be assigned even if the number is different. For this reason, many cable cores 3 are Although it is suitable, if the number 7 is the same color and the number of cable cores 3 increases. Unless the number of digits is increased, identification becomes impossible. For this purpose, a printing roll for printing numbers is required. In addition, numbers with many digits may be difficult to read or may be misread. This makes it difficult to identify. Therefore, if you do not want to increase the number of digits, By changing the color of the insulator 2 of the ground color of the cable core 3, it is the same for each cable core 3 of a different color. Display numbers (for example, 10 for insulators with a red background color, 10 for insulators with a blue background color) ) methods are being adopted. However, in this case, the color of insulator 2, which is the ground color, is It has the same drawbacks as the previous method because it has to be changed.

[Purpose of invention]

The purpose of this invention is to create an identification code that can be easily identified even when the number of cable cores is large. Providing multi-core cables that can be easily displayed and reduce waste of insulating material. It's about doing.

[0005]

[Means to solve the problem]

The multi-core cable according to claim 1 of the present invention has a ground on the outer periphery of the core wire 1 as shown in FIG. A multicore cable having two or more cable cores 3 coated with a colored insulator 2 Then mark the identification symbols 4 such as numbers and codes on the surface of the insulator 2 with the same ground color as the cable wire. Each three cores is displayed in a different color. The multi-core cable of claim 2 of the present invention is characterized by the identification of numbers, codes, etc. in claim 1. Separate symbols 4 are displayed at appropriate intervals in the longitudinal direction of the cable core 3, and furthermore, the identification symbol 4 In between, stripes 5 are displayed in different colors for each cable core 3.

[0006]

[Effect]

In the multi-core cable according to claim 1, since the ground-colored insulators 2 themselves have the same color, the ground-colored insulators 2 themselves have the same color. There is no need to worry about changing the color of the insulator 2. Also, on the surface of the ground-colored insulator 2, Since the color of the displayed identification symbols 4 such as numbers and codes is different for each cable core 3, the cable Even if the number of blue wire cores 3 increases, an unlimited number of different color identification symbols 4 can be displayed. . In the multi-core cable according to claim 2, identification of numbers, codes, etc. displayed on the ground-colored insulator 2 In addition to making the color of the symbol 4 different for each cable core 3, the identification symbol 4 is It is displayed at appropriate intervals in the longitudinal direction of the cable core 3, and in addition, it is displayed at appropriate intervals in the longitudinal direction of the cable core 3. Since stripes 5 are displayed in different colors, more cable cores 3 can be identified. I can do it.

[0007]

【Example】

As an embodiment of the multi-core cable of the present invention, the cable shown in FIG. Make all the insulators 2 of the reversed ground color the same color, and attach a cable to the surface of each insulator 2 of the ground color. Identification symbols 4 such as numbers and codes in different colors are displayed for each core 3. In this case, knowledge Separate symbols 4 are displayed in pairs with the top and bottom upside down as shown in Figure 5, and The pairs of identification symbols 4 are displayed at regular intervals in the longitudinal direction of the cable core 3. In the present invention, between the identification symbols 4 displayed at regular intervals in the longitudinal direction of the cable core 3, , display the stripes 5, and change the color of each stripe 5 for each cable core 3. You can also If the number of cable cores 3 in a multi-core cable is large, all cable cores 3 It is not necessary to make the ground color of the insulator 2 the same color, and in some cases many cable wires Divide the core 3 into groups of multiple cores (for example, if the cable core 3 is made up of 60 multi-core cables) (divided into 3 groups of 20 wires each), and set the color of the insulator 2 of the ground color for each cable core 3 of each group. (for example, 30 pieces in one set are red, 30 pieces in another set are blue, and 30 pieces in another set are red) A book is white), and each cable core 3 in a set of different colors has a different color. The identification symbol 4 may also be displayed. For example, if the ground-colored insulators 2 of the 12 cable cores 3 are all white, For example, to display the identification symbol 4 on the insulator 2 of the same background color, do as follows. ．． Prepare rolls No. 1 to 6 for number printing. ．． Two colors, black and red, are prepared as color printing ink. ．． Using the above roll on the insulator 2 with a white base color, numbers 1 to 6 (identification) are marked in black. Separate symbol) Print 4. ．． Use the roll to insulate the insulator 2, which has a white base color, and mark the numbers 1 to 6 in red. Separate symbol) Print 4. If identification symbol 4 is printed as described above, numbers 1 to 6 are used to mark the cable core. The discernible range of 3 is 12 lines. In addition, in this invention, rolls with many numbers (for example, rolls No. 1 to 10) are used, If you print it in multiple colors (for example, 3 colors), you can print more cable cores 3 (in this example). 30 lines) can be identified.

[0008]

[Effect of the idea]

The multi-core cable of the present invention has the following effects. ．． Color of printing ink for identification symbol 4 displayed on ground-colored insulator 2 of cable core 3 By changing the color for each cable core 3, the coloring of the ground color of the insulator 2 itself can be changed. Therefore, a large number of cable cores 3 can be identified. ．． The number of printing rolls required to print identification symbol 4 has also been significantly reduced, making printing easier. Roll handling and management become easier. ．． Since the only change is the color of the printing ink for identification symbol 4, it is necessary to change the printing ink. This reduces waste of time and colored insulating material when coloring. ．． If the stripe 5 is displayed in a different color for each cable core 3, fewer identification marks will be required. 4, more cable cores 3 can be identified. ．． Due to a printing defect in identification symbol 4, an identification failure may occur in cable core 3. Even if the material is exposed to the surface of the ground-colored insulator 2 without changing the covering of the ground-colored insulator 2, Since it is only necessary to reprint the indicated identification symbol 4, the modification becomes easy.
