A cable connection device includes a first holder, a second holder and a support. The first holder is configured to hold a tip part of an end of a cable. The second holder is configured to hold an intermediate part of the end. The support is configured to support the first holder. The second holder is fixed with respect to a power feed control device body. The first holder is supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable.

Cable connection device and power feed control device

A power feeding control apparatus includes a housing for accommodating at least a relay unit which opens and closes power feeding lines, a control circuit for controlling the relay unit, a leakage current detection circuit for detecting leakage current in the electric vehicle and a power supply circuit for generating a control electric power. The apparatus further includes a power source side connector and a vehicle side connector. The leakage current detection circuit includes a zero current transformer through which the power feeding lines extend and is configured to detect leakage current based on unbalanced currents flowing through the power feeding lines. Lead plates constitute a part of the power feeding lines and pass through a central opening of the zero current transformer, and the zero current transformer includes a positioning member molded within the central opening to fix the positions of the lead plates.

A feed control device includes a contact device, an output detector, a contact weld sensor, and an alarm device. The output detector is configured to detect the presence of power feeding into the side of an electrically-powered car from an external power supply. The contact weld sensor is configured to sense that the contact device is welded based on a detection result of the output detector if detecting the presence of power feeding from the external power supply to a feed line for the contact device when a state signal representing charge permission is not entered. The alarm device is configured, if the contact weld sensor senses that the contact device is welded, to indicate the occurrence of weld to the outside.

A power feeding control apparatus includes a housing for accommodating at least a relay unit arranged on power feeding lines to open and close the power feeding lines, a control circuit for controlling the relay unit, a leakage current detection circuit for detecting leakage current in an electric vehicle and a power supply circuit for generating a control electric power. The apparatus further includes a power source side connector removably connected to a socket of an external power source, a vehicle side connector removably connected to a power receiving connector of the electric vehicle and a first and a second board that the power supply circuit and the control circuit are mounted, respectively. A power feeding line block provided separately from the first and the second board and having metal plates constituting the power feeding lines. The metal plates are insertion-molded in the power feeding line block.

An electricity feeding control device is provided with an air hole () which is formed by penetrating a part of a peripheral wall of a body () constituting a part of a housing case (). The housing case () is provided in its inside with an inner pressure adjusting sheet (), formed with a breathable and waterproof member, and arranged so as to cover the air hole () from the inside of the housing case (). The air hole () comprises a long recess () formed in an outer surface of the body (), a communicating hole () consecutively formed in one end of a longi-tudinal direction of the recess () and communicated with an inner surface of the body (), and a shielding plate () attached in the outer surface of the body () so as to cover a region other than the other end of the longitudinal direction of the recess (), in a region of an opening section () of the recess (). That is, a channel of the air hole (), led from the inside to the outside of the housing case (), is formed into a nonlinear shape.
