Abstract

-- A first cover includes: a cover body portion that covers a wire insertion portion, a first engaging portion that extends from the cover body portion to a case body side, and is engaged with a first engagement portion of the case body, and a second engaging portion that extends from the cover body portion to the case body, and is engaged with a second engagement portion of the case body. A length in an extending direction of the first engaging portion is set longer than a length in an extending direction of the second engaging portion. Moreover, the case body includes a first regulation portion that abuts against a leading end portion in the extending direction of the first engaging portion when the first engaging portion is about to be engaged with the second engagement portion, and regulates displacement of the first engaging portion in an attachment direction.

First claim

1 . A battery wiring module to be attached to a secondary battery, comprising:
an electric wire to be electrically connected to the secondary battery; and a case that houses the electric wire, wherein the case includes a case body that has a wire insertion portion through which the electric wire is passed, and a cover that covers the wire insertion portion, the cover is formed separately from the case body, the case body includes a first engagement portion and a second engagement portion, the cover includes a cover body portion that covers the wire insertion portion, a first engaging portion that extends from the cover body portion to the case body side, and is engaged with the first engagement portion, and a second engaging portion that extends from the cover body portion to the case body side, and is engaged with the second engagement portion, a length in an extending direction of the first engaging portion is set longer than a length in an extending direction of the second engaging portion, and the case body includes a regulation portion that abuts against a leading end portion in the extending direction of the first engaging portion when the first engaging portion is about to be engaged with the second engagement portion, and regulates displacement of the first engaging portion in an attachment direction.

2 . The battery wiring module according to claim 1 ,
wherein the case body includes a third engagement portion, the cover includes a third engaging portion that extends from the cover body portion to the case body side, and is engaged with the third engagement portion, the length of the first engaging portion is set longer than a length of the third engaging portion in a direction that lies along an insertion direction of the electric wire, with the regulation portion being defined as a first regulation portion, the case body includes a second regulation portion on a lateral side of the third engagement portion in a direction that lies along the insertion direction of the electric wire, and when the first engaging portion is about to be engaged with the third engagement portion, the second regulation portion abuts against the first engaging portion, and regulates displacement of the first engaging portion in the attachment direction.

3 . The battery wiring module according to claim 1 ,
wherein the wire insertion portion includes a bottom wall portion and a pair of side wall portions extending from the bottom wall portion,
a slit is provided in the side wall portions, and
the cover includes a protrusion portion fitted into the slit.
