Description

technical field

[0001] The present invention relates to a power supply cable and a power supply cable with a connector.

[0002] This application claims priority based on Japanese Patent Application No. 2016-149405 for which it applied to Japan on July 29, 2016, and uses the content here. Background technique

[0003] In recent years, along with the popularization of electric vehicles and the like, for example, a power supply cable capable of carrying a large current of about 250 A has been demanded. In such a power supply cable, a temperature rise in the interior of the power supply cable and on the surface of the power supply cable (hereinafter, simply referred to as "inside and outside the power supply cable") is a problem due to energization of a large current. In order to prevent deterioration of components and comply with standards (for example, IEC62196-1-16.5, etc.), the temperature inside and outside the power supply cable needs to be kept below a predetermined tem...

Examples

no. 1 approach

[0035] Below, refer to figure 1 , figure 2 The structure of the power supply cable according to the first embodiment will be described. In each drawing used in the following description, the scale and dimensions are appropriately changed for easy understanding.

[0036] Such as figure 1 As shown, the power supply cable 1 is provided with a plurality of power lines 10 , an inclusion 2 , a plurality of auxiliary lines 3 , and a sheath 4 . In the present embodiment, the power supply cable 1 includes two (even-numbered) power lines 10 .

[0037] The power supply cable 1 is, for example, a power supply cable conforming to the CHAdeMO standard capable of fast charging an electric vehicle battery. When the cable 1 is used, a large current of, for example, about 250 A flows in the power line 10 . When the cable 1 is used, the user may directly contact the surface of the sheath 4 , so it is necessary to keep the temperature of the surface of the sheath 4 within a predetermined ra...
