Abstract A battery box of high reliability wherein a leaf spring terminal does not readily suffer from settling even if external forces such as vibrations or impacts are applied. The battery box comprises a leaf spring terminal secured to an inner wall of a battery accommodating case for contacting with an electrode of a battery received in the cavity of the battery accommodating case. The leaf spring terminal has a resilient supporting portion having a substantially U-shape and is secured at the opposite end portions thereof to the inner wall of the battery accommodating case. The leaf spring terminal further has a resilient tongue which is folded over itself and a base portion which extends from the bottom of the U-shape of the resilient supporting portion in the same plane as and in parallel to the opposite sides of the U-shape of the resilient supporting portion with a pair of slits left therebetween. The inner wall of the battery accommodating case has a recess formed at a portion opposite to the base portion of the resilient tongue of the leaf spring terminal to allow the base portion of the resilient tongue to be deflected therein.
A battery box comprising: a battery accommodating case having a cavity defined for removably receiving battery therein; and a leaf spring terminal secured to an inner wall of said battery accommodating case for contacting with an electrode of a battery received in said cavity of said battery accommodating case, said leaf spring terminal having a resilient supporting portion with an overall, substantially U-shape, wherein said leaf spring terminal is secured at the opposite end portions of the U-shape of said resilient supporting potion thereof to said inner wall of said battery accommodating case; said leaf spring terminal further having a resilient tongue which is folded over itself, said resilient tongue having a base portion extending in the form of a cantilever from the bottom of said U-shape of said resilient supporting portion in the same plane as and in parallel to the opposite sides of said resilient supporting portion with a pair of slits left therebetween; said inner wall of said battery accommodating case having a recess formed at a portion opposite to said base portion of said resilient tongue of said leaf spring terminal to allow said base portion of said resilient tongue to be deflected therein.

A battery box comprising: a battery accommodating case having a cavity defined for removably receiving battery therein; and a leaf spring terminal secured to an inner wall of said battery accommodating case for contacting with an electrode of a battery received in said cavity of said battery accommodating case, said leaf spring terminal having a resilient supporting portion with an overall, substantially U-shape, wherein said leaf spring terminal is secured at the opposite end portions of the U-shape of said resilient supporting potion thereof to said inner wall of said battery accommodating case; said leaf spring terminal further having a resilient tongue which is folded over itself, said resilient tongue having a base portion extending in the form of a cantilever from the bottom of said U-shape of said resilient supporting portion in the same plane as and in parallel to the opposite sides of said resilient supporting portion with a pair of slits left therebetween; said inner wall of said battery accommodating case having a recess formed at a portion opposite to said base portion of said resilient tongue of said leaf spring terminal to allow said base portion of said resilient tongue to be deflected therein.
Claim 3
Dependent Claim
52 words
A battery box according to claim 1, wherein said base portion of said resilient tongue of said leaf spring terminal extends to a folded portion wherein said resilient tongue is folded over itself such that said folded portion is level with the opposite ends of the U-shape of said resilient supporting portion.
Claim 4
Dependent Claim
38 words
A battery box according to claim 1, wherein the opposite end portions of the U-shape of said resilient supporting portion of said leaf spring terminal are secured to said inner wall of said battery accommodating case by caulking.
Claim 5
Dependent Claim
52 words
A battery box according to claim 1, wherein the opposite end portions of the U-shape of said resilient supporting portion of said leaf spring terminal are inserted in a pair of slits formed in said wall of said battery accommodating case to secure said leaf spring terminal to said battery accommodating case.
