Abstract
Abstract A method of making an intercell connection in a storage battery comprising connecting a pair of connectors to two cell element assemblies respectively on opposite sides of a battery partition wall, providing a connecting projection of one of the connectors so that it extends through an opening in the partition wall into an aperture in the other connector, pressing these two connectors against the partition wall, and welding the connecting projection to the inner wall of the aperture in the other connector by carrying out inert gas shielded arc welding on one side of the partition wall.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A method of making intercell connection in a storage battery comprising arranging a pair of connectors integral with respective conductive straps of battery cell element assemblies on opposite sides of a battery partition wall having an opening, providing a connecting projection on one of said connectors so that it can extend through said opening in said partition wall into an aperture in the other said connector, pressing said connectors against said partition wall by a pair of pressure applying means while inserting said projection through said opening in said partition wall into said aperture in the other said connector, and welding the surface portion of said inserted projection to the inner wall of said aperture of the other connector by an arc substantially surrounded, cooled and concentrated by an injected inert gas on one side of said partition wall thereby connecting said connectors with each other.
Claim 2
Independent Claim
146 words
A method of making intercell connection in a storage battery comprising arranging a pair of connectors integral with respective conductive straps of battery cell element assemblies on opposite sides of a battery partition wall having an opening, providing a connecting projection on one of said connectors so that it can extend through said opening in said partition wall into an aperture in the other said connector, pressing said connectors against said partition wall by a pair of pressure applying means while inserting said projection through said opening in said partition wall into said aperture in the other said connector, and welding the surface portion of said inserted projection to the inner wall of said aperture of the other connector by an arc substantially surrounded, cooled and concentrated by an injected inert gas on one side of said partition wall thereby connecting said connectors with each other.
Claim 3
Dependent Claim
22 words
A method of making an intercell connection as claimed in claim 1, in which said connectors are welded together by plasma welding.
Claim 4
Independent Claim
145 words
A method of making an intercell connection in a storage battery comprising arranging a pair of connectors integral with respective conductive straps of battery cell element assemblies on opposite sides of a battery partition wall having an opening, providing a columnar connecting projection on one of said connectors at the face opposite to said partition wall so that it can extend through said opening in said partition wall into an aperture in the other said connector, bringing said connectors into intimate contact with said partition wall by pressing said connectors against said partition wall by a pair of pressure applying means so as to maintain the engagement between said projection and said aperture, and heating the engaging portions of said projection and said aperture with a plasmatic arc shielded by an inert gas thereby welding said projection to the inner wall portion of said aperture.
Claim 5
Independent Claim
145 words
A method of making an intercell connection in a storage battery comprising arranging a pair of connectors integral with respective conductive straps of battery cell element assemblies on opposite sides of a battery partition wall having an opening, providing a columnar connecting projection on one of said connectors at the face opposite to said partition wall so that it can extend through said opening in said partition wall into an aperture in the other said connector, bringing said connectors into intimate contact with said partition wall by pressing said connectors against said partition wall by a pair of pressure applying means so as to maintain the engagement between said projection and said aperture, and heating the engaging portions of said projection and said aperture with a plasmatic arc shielded by an inert gas thereby welding said projection to the inner wall portion of said aperture.
Claim 6
Dependent Claim
71 words
A method of making an intercell connection as claimed in Claim 3, in which at least one of said connectors is provided with an annular projection having an inner diameter larger than the diameter of said opening in said partition wall at the face opposite to said partition wall, and said annular projection is forced into said partition wall by the pressure applied to said connector by said pressure applying means.
Claim 7
Dependent Claim
91 words
A method of making an intercell connection as claimed in Claim 3, in which a plurality of alternate convexities and concavities are formed in the peripheral wall of said aperture in the other said connector which receives therein said connecting projection extending through said opening in said partition wall so that such convexities and concavities are readily fluidized by the heat of the arc thereby connecting the end portion of said connecting projection on one of said connectors with the inner wall portion of said aperture in the other said connector.
Claim 8
Dependent Claim
73 words
A method of making an intercell connection as claimed in claim 3, in which a sealing packing is interposed between said partition wall and one of said connectors having said connecting projection extending through said opening in said partition wall, and said connecting projection is welded to the inner wall portion of said aperture in the other said connector while maintaining said packing compressed by the pressure applied by said pressure applying means.
Claim 9
Dependent Claim
63 words
A method of making an intercell connection as claimed in claim 3, in which a pair of sealing packings is interposed between said partition wall and each of said connectors, and said connecting projection is welded to the inner wall portion of said aperture in the other said connector while maintaining said packings compressed by the pressure applied by said pressure applying means.
