Abstract

A voltage detection unit includes a voltage detection terminal, a housing including a terminal accommodating concave and a cover to he attached to the housing and to cover the voltage detection terminal accommodated in the terminal accommodating concave. The cover includes an extension piece extending in a first direction. The housing includes an accommodating hole to accommodate the extension piece, and a guide portion including an inclined surface and a guide surface. The inclined surface has a first end in the first direction and a second end and is inclined with respect to the first direction such that the first end is provided closer to the accommodating hole than the second end in a second direction perpendicular to the first direction and being parallel to the housing. The guide surface is continuous with the inclined surface and an inner wall surface of the accommodating hole.

First claim

What ls claimed is:

1 . A voltage detection unit comprising:
a voltage detection terminal configured to be conductively connected to a detection target; a housing having a plate shape and including a terminal accommodating concave configured to accommodate the voltage detection terminal: and a cover configured to be attached to the housing and to cover the voltage detection terminal accommodated in the terminal accommodating concave, wherein the cover includes an extension piece extending in a first direction in which the cover is attached to the housing, and wherein the housing includes an accommodating hole configured to start accommodating the extension piece as the cover moves in the first direction for the cover to he attached to the housing, and a guide portion including an inclined surface and a guide surface, wherein the inclined surface has a flat shape and has a first end in the first direction and a second end opposite to the first end and is inclined with respect to the first direction such that the first end is provided closer to the accommodating hole than the second end in a second direction perpendicular to the first direction and being parallel to a plane in which the housing having the plate shape extends, and wherein the guide surface is continuous with the inclined surface and an inner wall surface of the accommodating hole.

2 . The voltage detection unit according to claim 1 ,
wherein the cover includes a locking portion configured to engage with a predetermined portion of the housing and to restrict movement of the cover along the first direction, and wherein the guide portion is disposed such that the extension piece is located between the predetermined portion and the guide portion.

3 . The voltage detection unit according to claim 1 .
wherein the extension piece has a rectangular shape in which an extended end portion of the extension piece is not chamfered.
