A concentration of the aqueous PVA solution is 10-15 %.
Abstract:
A wiring harness 1 includes: an electric wire 2; and a connector 3. The electric wire 2 includes: a conductive core wire 21; and an insulating cover 22 for covering the core wire 21. The connector 3 is attached to an end 2a of the electric wire 2, and receives the end 2a of the electric wire 2. A first marker 6 and a second marker 7 are formed on an outer surface 22a of the cover 22 of the electric wire 2. The first marker 6 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 received in the connector 3 in a color A. The second marker 7 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 exposed to an outside of the connector 3.
Abstract:
There is provided an electric wire 1 comprising an electrically-conductive conductor portion and an insulating cover portion 11 covering the conductor portion. A colored marker 13 is provided on an end portion of the cover portion 11. The colored marker 13 indicates that the electric wire is a manually-incorporated wire. A circuit identifier 12 is provided on an intermediate portion of the cover portion 11. The circuit identifier 12 is made by printing or provided in the form of a mark and indicative of a connection destination of the electric wire 1. The colored marker in the end portion is made by an ink inferior to that of the circuit identifier on the intermediate portion in at least one property selected from among adhesiveness, weatherability, heat resistance, and chemical resistance.
Abstract:
A method and a system of manufacturing electric wires by ordering, possible to save the cost and materials, is provided. A system includes an order-receiving section, a manufacturing section and a coloring/cutting section. The order-receiving section receives orders of electric wires, and outputs a first datum of amount of electric wires DT1, informing a length of a monochromatic electric wire, and outputs a second datum of amount of electric wires DT2, informing lengths for respective colors of electric wires. The manufacturing section manufactures a monochromatic electric wire according to the first datum DT1 and conveys the electric wire to the coloring/cutting section. The coloring/cutting section colors and cuts the electric wire according to the second datum DT2.
Abstract:
The present invention provides a marking ink for a covered electrical conductor utilized for a wire harness of a motor vehicle. The marking ink is printed on the covered conductor formed with polyolefin such as polyethylene and provides a high adherence (coloring), high wear resistance, high productivity, fast drying, and moderate spreading. The marking ink for the covered electrical conductor contains an acrylate resin with molecular weight of 10,500-93,000.
Abstract:
This invention intends to provide a method and apparatus for manufacturing an electric wire, capable of easily changing a color applied to the electric wire. The electric wire manufacturing apparatus intends to manufacture an electric wire composed of a core and a cladding. In step S1, the core is supplied from a supply unit. In step S2, in an extrusion cladding unit, the outer periphery of the core is coated with non-color synthetic resin by extrusion cladding to form the cladding. In step S3, the outer surface of the cladding is colored by a coloring unit. The coloring unit includes a plurality of sprayers 15 and 16. In step S3, the sprayers 15 and 16 are exchanged to operate as necessary. In step S4, in a take-up unit, the electric wire is cut into segments each having a desired length, which are wound around a drum.
Abstract:
The invention provides an electrical cable reuse method which reduces a long time stock of cables. For assembling a wiring harness, step S1 reuses special electrical cables stocked in an electrical cable storehouse, and the cables having been colored in a first color are coated with a second color. Step 2 cuts ordinary cables and special cables each in a desired length, removes a part of a cable sheath of each cable, and fits a terminal piece to the exposed part. Step 3 connects ordinary cables and the special cables with each other. Step 4 inserts the terminal piece into a connector housing.
Abstract:
An object of this invention is to provide a connector housing which can be prevented a terminal-receiving chamber from receiving a wrong metal terminal.A connector housing 1 comprises a plurality of terminal-receiving chambers 20 and a plurality of marks 21. The terminal-receiving chamber 20 receives a male terminal 3. Electric wire 2 is attached to the male terminal 3. A mark 6 is formed on an outer surface 5a of the electric wire 2. A color of the mark 6 of one electric wire 2 is a first color R. A color of the mark 6 of the other electric wire 2 is a second color G. The first color R is different from the second color G. The mark 21 corresponds to each terminal-receiving chamber 20. A color of one mark 21 is the first color R, which is the same as the color of the mark 6 of the one electric wire 2. A color of the other mark 21 is the second color G, which is the same as the color of the mark 6 of the other electric wire 2. By forming the mark 21 in a same color as the mark 6 of the electric wire 2 attached to the male terminal 3 which is to be inserted into the terminal-receiving chamber 20 corresponding to the mark 21, the mark 21 indicates the male terminal 3 to be received by the terminal-receiving chamber 20 corresponding to the mark 21.

The device 1 includes first and second spouting means 311, 321, encoder 33 and control device 34. The first spouting means 311 spouts a specific amount of a first coloring agent toward the outer surface 3a of the electric wire 3. The second spouting means 312 spouts a specific amount of a second coloring agent toward the outer surface 3a of the electric wire 3. The encoder 33 detects a transfer speed of the electric wire 2 which is transferred in a direction of arrow K. The control device 34 makes the first and second spouting means 311, 312 spout the coloring agent according to a pattern predetermined in advance in response to the transfer speed of the wire 3 detected by the encoder 33.
