Description

This disclosure relates to cables. Patent Document 1 discloses a connector in which a braided copper wire is provided on the outer circumference of a high-voltage cable as a countermeasure against electromagnetic noise. In this technology, the braided copper wire is crimped to a bracket for grounding. Japanese Patent Publication No. 2023-165259 Figure 1 is a cross-sectional view showing a schematic configuration of a cable according to one embodiment of the present disclosure. The following description will focus on cables comprising the embodiments of this disclosure, with reference to the drawings. Note that the components in the following embodiments include those that are easily substituted or substantially identical to those that are easily substituted by those skilled in the art. Furthermore, the figures referenced in the following description are merely schematic representations of the shapes, sizes, and positional relationships to the extent necessary to understand the content of this disclosure. In other words, this disclosure is not limited to the shapes, sizes, and positional relationships illustrated in the figures. [Outline configuration of a wire harness] Figure 1 is a cross-sectional view showing a schematic configuration of a cable according to one embodiment of the present disclosure. The cable 1 (wire harness) shown in Figure 1 comprises a connector 2, a shielded wire 3, a bracket 4, a braided copper wire 5, a metal band 6, a pipe 7, a rubber boot 8, and a rubber ring 9. Connector 2 is connected to the end of the shielded wire 3 and is also fixed to the body 100 of the vehicle to which it is attached. The shielded wire 3 is composed of a core wire and an insulating sheath covering the outer circumference of the core wire. The shielded wire 3 is constructed using at least one core wire. Bracket 4 is made of a plate material and is formed to cover a portion of the outer circumference of the connector 2 and the shielded wire 3. The braided copper wire 5 is formed to cover a portion of the outer circumference of the end of the bracket 4 and the outer circumference of the shield wire 3. The braided copper wire is a braided wire in which conductive strands of copper alloy or aluminum alloy are woven together in a tubular shape. The metal band 6 is ring-shaped to cover the outer surface of the braided copper wire 5, and is crimped and secured to the end of the bracket 4 and the braided copper wire 5 towards the center. This secures the braided copper wire 5 to the outer surface of the bracket 4. Pipe 7 is constructed from a cylindrical pipe material. Pipe 7 is formed by applying expansion (widening) or contraction (reducing) processes to a metal pipe material of a constant diameter. A shielded electric wire 3 is inserted inside pipe 7. The rubber boot 8 is cylindrical and is fixed in place with the bracket 4 and pipe 7 inserted inside, covering at least the outer circumference of the metal band 6. This prevents water from entering from the outside, thus preventing corrosion of the metal band 6. As a result, cannibalization can be prevented. The rubber ring 9 is ring-shaped and is provided between the bracket 4 and the connector 2. This prevents water from entering the gap between the bracket 4 and the connector 2 from the outside. In this configuration, the rubber boot 8 prevents water from entering the cable 1 from the outside, thus preventing corrosion of the metal band 6. As a result, cannibalistic corrosion of the cable 1 can be prevented. According to the embodiment described above, since the rubber boot 8 is fixed with the bracket 4 and pipe 7 inserted inside so as to cover the outer circumference of the metal band 6, water intrusion from the outside is prevented, thus preventing corrosion of the metal band 6. As a result, cannibalistic corrosion can be prevented. Furthermore, in one embodiment, since the rubber ring 9 is provided in the gap between the bracket 4 and the connector 2, it is possible to prevent water from entering from the outside. Further effects and modifications can be readily derived by those skilled in the art. Broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents. Although several embodiments of this application have been described in detail above with reference to the drawings, these are illustrative examples, and the present invention can be implemented in various modified and improved forms based on the knowledge of those skilled in the art, starting with the embodiments described in the disclosure section of the present invention.
