Abstract

A battery spacer includes: a storage case having a bottomed cylindrical shape in which a battery is stored; a lid part which closes an opening of the storage case; and a positive electrode relay terminal which is provided to the lid part, a part of which protrudes from a top surface of the lid part, and which abuts on a positive electrode terminal of the battery in the storage case. The lid part has a protruding section formed which protrudes further to the battery side than a terminal contact surface at which the positive electrode terminal of the battery abuts on the positive electrode relay terminal. The protruding section has a protruding length h, in the axial direction of the battery, from the terminal contact surface, shorter than the length H of the positive electrode terminal of the battery, and has an annular shape having a diameter R that is larger than the diameter r of the positive electrode terminal of the battery and is smaller than the diameter S of the battery in the radial direction of the battery.

First claim

The invention claimed is:

1. A battery spacer comprising:
a battery storage part having a bottomed cylindrical shape in which a battery is stored;
a lid part which closes an opening of the battery storage part; and
a positive electrode relay terminal which is provided to the lid part, a part of which protrudes from a top surface of the lid part, and which abuts on a positive electrode terminal of the battery in the battery storage part, wherein
the lid part has a protruding section formed which protrudes further toward a battery side than a surface of the positive electrode relay terminal to abut on the positive electrode terminal of the battery, and
the protruding section has a protruding length, in an axial direction of the battery, from the surface of the positive electrode relay terminal to abut on the positive electrode terminal of the battery, shorter than a length of the positive electrode terminal of the battery, and is formed in a range outside the positive electrode terminal of the battery but inside an outer circumferential surface of the battery in a radial direction of the battery, wherein
the protruding section has an annular shape having a diameter that is larger than a diameter of the positive electrode terminal of the battery and is smaller than a diameter of the battery, and radially surrounds the surface of the positive electrode relay terminal to abut on the positive electrode terminal of the battery.

2. The battery spacer according to claim 1 , further comprising:
a negative electrode relay terminal which is provided on a bottom section of the battery storage part, a part of which is exposed from an outer bottom surface of the battery storage part, and which abuts on a negative electrode terminal of the battery in the battery storage part, wherein
the battery storage part has a recess section formed in the outer bottom surface, and
the part of the negative electrode relay terminal exposed from the outer bottom surface of the battery storage part is located in the recess section.
