Abstract

A battery connector includes: a plurality of terminals, each of which is to be connected to each electrode of a plurality of batteries; a plurality of voltage detection terminals, each of which is connected to respective one of the terminals, and includes a wire connection part to be connected to an electric wire; and a case which contains the plurality of terminals and the plurality of voltage detection terminals therein. Adjacent terminals of the terminals are fixed in the case to be spaced from each other, and an individual wire path of a wire routing part is provided between the adjacent terminals. Each of the voltage detection terminals is fixed so as to incline the wire connection part with respect to the individual wire path and to locate the wire connection part more interiorly than an edge of the case.

First claim

What is claimed is:

1. A battery connector, comprising:
a plurality of terminals configured to connect a plurality of batteries;
a plurality of voltage detection terminals, each of which is connected to one of the plurality of terminals, each of the voltage detection terminals comprising a wire connection part configured to be connected to an electric wire; and
a case which contains the plurality of terminals and the plurality of voltage detection. terminals therein, wherein
the plurality of terminals are fixed in the case to be spaced from each other such that an individual wire path of a wire routing part is provided between adjacent terminals, and of the plurality of terminals, and
each of the plurality of voltage detection terminals is fixed such that the wire connection part is slanted with respect to the individual wire path.

2. The battery connector according to claim 1 , wherein an angle between the wire connection part and the individual wire path is 45 degrees.

3. The battery connector according to claim 1 , comprising:
a plurality of covers, of which adjacent covers are closely disposed, wherein
a face of the case in which the each of the plurality of terminals and the voltage detection terminals are disposed is covered by the plurality of covers, and
each of the covers is provided with a rib which protrudes toward the case from a side end of an inner surface of each of the covers.

4. The battery connector according to claim 1 , comprising:
a connector fixing part to which a connector is to be fixed, wherein
the wire routing part includes a bundle wires path, an end of which is connected to the connector fixing part, and the bundle wires path is connected to the respective individual wire paths to guide electric wires extended from respective wire connection parts to the connector fixing part.

5. A battery connector, comprising:
a plurality of terminals configured to connect a plurality of batteries;
a plurality of voltage detection terminals, each of which is connected to one of the plurality of terminals, each of the plurality of voltage detection terminals comprising a wire connection part configured to be connected to an electric wire; and
a case which contains the plurality of terminals and the plurality of voltage detection terminals therein, wherein
the case is provided with a plurality of terminal fixing parts on which the plurality of terminals are fixed, such that the plurality of terminals are aligned in an alignment direction and spaced from each other, and
each of the plurality of voltage detection terminals is fixed on a corresponding one of the plurality of terminal fixing parts such that the wire connection part is slanted with respect to the alignment direction.

6. The battery connector according to claim 5 , wherein
each of the plurality of terminal fixing parts has a rectangular shape with a long side in the alignment direction and a short side in a direction orthogonal to the alignment direction, and
the wire connection of each of the plurality of voltage detection terminals is disposed at a corner part of the terminal fixing part at which the long side of the terminal fixing part intersects with the short side.

7. The battery connector according to claim 5 , wherein
the case includes a wire routing part comprising a plurality of individual wire paths disposed between the plurality of terminal fixing parts and a bundle wires path disposed along the alignment direction and connecting the plurality of individual wire paths, and
each of the plurality of voltage detection terminals is fixed so that the wire connection part is directed toward a side of one of the plurality of individual wire paths.

8. The battery connector according to claim 7 , wherein the plurality of wire paths are perpendicular to the bundle wires path.
