Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a branch cable used as a trunk cable for buildings such as buildings and condominiums.

[0002]

2. Description of the Related Art Conventionally, a cable with a branch used for a building such as a building or a condominium has been prepared after a specification has been prepared in accordance with the specification of the building and the consent of a customer has been obtained. Specifically, the customer receives a wiring diagram from the customer, creates a detailed branching diagram that matches the wiring diagram, submits specifications to the customer, checks for changes, confirms consent, etc. There was a process, and the construction company, distribution and technical departments exchanged information in their respective roles.

[0003]

According to the conventional method described above, at the stage of specification creation, each person in charge of a construction company, a distribution company, and a technical department needs to exchange information related to the acceptance of specifications. Then, it was necessary to design and specify the factory according to the specifications, which required much administrative work and many problems such as mistakes. Furthermore, since the materials cannot be prepared in advance, a lead time for the delivery date is required, and there is a case where it is difficult to request a short delivery date. The present invention has been made in view of the above-described circumstances, and provides a method of manufacturing a cable with a branch, which does not require the creation of a specification sheet, facilitates a manufacturing instruction, and can be manufactured and delivered in a short time. is there.

[0004]

In order to solve the above-mentioned problems, in the present invention, a plurality of types of branched cables are provided in which branch lines of a predetermined length are drawn out at standardized intervals. And the branch interval of the cable with branch,
Select the cable size, specify the number of branches, the length of one or both ends of the cable with branch, select the cable with branch that can satisfy the above conditions from the above multiple types of cables with branch, and satisfy the specified conditions The cable is cut to a predetermined length as described above, and a cable of a specific length satisfying the above conditions is connected to one end or both ends. One end is assumed to be a long cable reaching the cubicle. Also, the cable to be added may be slightly modified, for example, by using a branch cable.

[0005] By manufacturing a cable with a branch as described above, it is not necessary to prepare a trunk line of a predetermined length according to the specification every time and connect the branch line. Can be manufactured. In general, a cable with a branch comprises a main cable carrying power and a ground wire supported alongside the main cable. In addition, standardize the branch interval and cable size of the cable with branch, standardize the method of specifying the number of branches and the length of one or both ends of the cable with branch, and specify the branch cable by specifying the model number and number. By doing so, it is possible to extremely easily issue a production instruction without creating a specification or the like. Furthermore, by giving a symbol that can easily imagine the cable size and the branch interval to the above-mentioned model number, or by specifying a number that allows the shape to be easily imagined, mistakes during ordering and production can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, branched cables having the following shapes and various cable sizes are prepared in advance. Also, a combination of trunk line and branch line sizes is set in advance, and the cable size is selected from combinations prepared in advance. As the configuration of the trunk line, the power cable and the ground line can be of different types. The distance between branches is 2.8m, 2.9m The direction of taking out the branch line is constant. The length of the branch line is 3m. The length of the trunk cable prepared in advance is equal to or longer than the required cable length, and the number of branch points can be set to an arbitrary number by cutting the prepared cable with branch.

FIG. 1 is a view showing an example of a cable with a branch manufactured according to the present invention. FIG. 1A shows a branch cable with a branch interval of 2.8 m, and FIG. 1B shows a branch cable with a branch interval of 2.9 m.
3 shows an example of a branch cable. In the figure, 1 is a trunk line, 2 is a branch line, a cable with a branch is molded insulated, and the trunk line 1 and the branch line 2 (vinyl insulated wire) are of a predetermined size as shown in FIG. Of the cable CVT and the ground line IV. A hanging net 3 is attached to the upper end of the branch cable. In the present embodiment, a cable with a branch can be specified by designating a model number and a number. The cable with a branch has a model number configuration, the number of branches, an A dimension,
It can be specified by the L dimension and the trunk line number. Table 1 shows an example of model number-numerical designation when specifying a cable with a branch, and the meaning of symbols and numerals.

[0008]

[Table 1]

In this embodiment, the branch cable shown in FIG. 1 is manufactured as follows. (1) Select a cable with branch according to the specified model number from the cables with branch prepared in advance. (2) Cut the cable with the branch so that the specified number of branches is reached. At this time, if the branch interval is equal to or longer than the A dimension, the cable is cut such that the length of the cable from the center of the branch portion becomes the A dimension. Also, if the branch interval is A
If it is smaller than the dimension, after cutting the cable with branch, a new cable is prepared and a new cable is connected so that the distance from the branch to the upper terminal is A dimension. (3) Attach the hanging net 3 to the end of the cut or newly added cable. (4) A new cable 4 is connected to the other end of the cut-off branch cable, if necessary, as in (2), so that the specified L dimension is obtained.

[0010]

As described above, according to the present invention, a plurality of types of branched cables in which predetermined lengths of branch lines are drawn out at standardized intervals are prepared, and the branch intervals of the branched cables are determined. Select the cable size, and according to the number of branches and the length of one or both ends of the cable with branch,
Since the cable with branch is cut to a predetermined length and a cable of a specific length satisfying the above conditions is connected to one end or both ends, the following effects can be obtained. (1) Branch cables required in a short time can be manufactured and delivered to customers. (2) If the number of branches of a cable with a branch, the branch interval, the cable size, and the specification method of one end or both ends of the cable with a branch are standardized, the branch cable can be specified by specifying the model number and number. It is possible to extremely easily issue a production instruction without preparing a specification sheet or the like. (3) A mistake in ordering or manufacturing can be reduced by adding a symbol to the model number to easily imagine the cable size or branch interval or by specifying a number to easily imagine the shape.
