Abstract
Abstract A battery holder for a coin cell provided with a casing which receives the coin cell against its bottom and laterally constrains the cell by a peripheral barrier wall. One pole of the cell is engaged by an electrical contact extending across the casing bottom, and the other pole of the cell is engaged by another electrical contact extending across the cell in resilient contact with the other pole thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, and comprises at least one projecting member on the bottom of said casing disposed for insertion into a matching hole of a support means to secure the battery holder thereupon.
Claim 2
Dependent Claim
108 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, and comprises at least one projecting member on the bottom of said casing disposed for insertion into a matching hole of a support means to secure the battery holder thereupon.
Claim 3
Dependent Claim
104 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing is generally circular to accomodate holding a circular coin cell, and including a transversely projecting portion that receives and holds said second contact.
Claim 4
Dependent Claim
104 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing is generally circular to accomodate holding a circular coin cell, and including a transversely projecting portion that receives and holds said second contact.
Claim 5
Dependent Claim
103 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing bottom has an aperture and said first contact extends across said aperture to allow flexure of the first contact into said aperture.
Claim 6
Dependent Claim
103 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing bottom has an aperture and said first contact extends across said aperture to allow flexure of the first contact into said aperture.
Claim 7
Dependent Claim
93 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing bottom has a recess that receives and laterally constrains said first contact.
Claim 8
Dependent Claim
93 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said casing bottom has a recess that receives and laterally constrains said first contact.
Claim 9
Dependent Claim
144 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said peripheral barrier means has a top surface which is configured to match the circumference of a standard coin cell whereby no electrical contact can be made to said first electrically conductive contact by said standard coin cell if it is inserted into said holder with a pole of opposite polarity to that of said first electrically conductive contact facing said first electrically conductive contact.
Claim 10
Dependent Claim
144 words
A battery holder for a coin cell, which comprises a casing having a bottom and a peripheral barrier means disposed to receive a coin cell against the bottom and laterally constrained by the peripheral barrier means; a first electrically conductive contact extending along said bottom of the casing to engage one pole of the coin cell, and a second electrically conductive contact extending above the bottom of the casing to engage the other pole of the coin cell, wherein said peripheral barrier means has a top surface which is configured to match the circumference of a standard coin cell whereby no electrical contact can be made to said first electrically conductive contact by said standard coin cell if it is inserted into said holder with a pole of opposite polarity to that of said first electrically conductive contact facing said first electrically conductive contact.
