Abstract

Included are a battery terminal connected to a battery post erected on a first surface of a battery, a battery connection unit provided with an electronic component connected to the battery terminal and to which ends of electric wires are connected, and a accommodating member that accommodates the battery terminal and the battery connection unit. The accommodating member has a through-hole through which the battery post is inserted, a terminal accommodating chamber in which a free end side of the battery post inserted through the through-hole is arranged and which accommodates the battery terminal connected to the free end side, and a butting portion that is projected from a periphery of the through-hole toward the first surface of the battery and made abut on the first surface.

Claims

1. A power source connection system comprising:

a battery terminal that is physically and electrically connected to a battery post erected on an outer wall surface of a battery;

a battery connection unit provided with an electronic component which is physically and electrically connected to the battery terminal and to which ends of electric wires drawn outward are physically and electrically connected; and

an accommodating member configured to accommodate the battery terminal and the battery connection unit, wherein

the accommodating member has a through-hole through which the battery post is inserted, a terminal accommodating chamber in which a free end side of the battery post inserted through the through-hole is arranged and which accommodates the battery terminal physically and electrically connected to the free end side, and a butting portion which is projected from a periphery of the through-hole toward the outer wall surface of the battery and made to abut on the outer wall surface.

2. The power source connection system according to claim 1, wherein

the butting portion is cylindrically formed to enclose an outer peripheral wall of the battery post with an inner peripheral wall of the butting portion and has an annular end portion in an axial direction made abut on the outer wall surface.

3. The power source connection system according to claim 1, wherein

the electronic component is a fuse circuit body.

4. The power source connection system according to claim 2, wherein

the electronic component is a fuse circuit body.
