Abstract
Abstract A battery comprising a row of individual cells each with positive and negative terminal posts and with connector straps between successive cells is provided with post-strap insulative caps which are pressed down in engagement with the post-strap connectors to provide protective sheaths against accidental shorting of one or more of the cells. In instances where it is desired to be able to make intermediate tap connections to the battery, a top wall section of one end portion of each cap is provided with a diaphragm thickness to enable it to be readily fractured and removed to provide access to the selected terminal post for a tap connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A battery comprising a plurality of individual cells having cases permitting the cells to be set side-by-side in rows and having upright terminal posts of positive and negative polarity, each with threaded end portions, said cells being arranged with the terminal post of one polarity of one cell adjacent to a terminal post of the opposite polarity of the next cell, post connectors between successive cells each comprising upper portions of a pair of said adjacent posts and a metal strap having apertured end portions fitted on said upper portions, nuts threaded on said posts to secure said straps thereto, and an insulative cap for each of said post connectors having a channelshaped central portion covering said metal strap and having hollow end portions covering the respective terminal posts connected to said strap, each of said hollow end portions of each of said caps having inteRnal elements releasably engaging the respective terminal posts to hold the cap in place over a post connector in response to pressing the cap thereon.
Claim 2
Dependent Claim
170 words
A battery comprising a plurality of individual cells having cases permitting the cells to be set side-by-side in rows and having upright terminal posts of positive and negative polarity, each with threaded end portions, said cells being arranged with the terminal post of one polarity of one cell adjacent to a terminal post of the opposite polarity of the next cell, post connectors between successive cells each comprising upper portions of a pair of said adjacent posts and a metal strap having apertured end portions fitted on said upper portions, nuts threaded on said posts to secure said straps thereto, and an insulative cap for each of said post connectors having a channelshaped central portion covering said metal strap and having hollow end portions covering the respective terminal posts connected to said strap, each of said hollow end portions of each of said caps having inteRnal elements releasably engaging the respective terminal posts to hold the cap in place over a post connector in response to pressing the cap thereon.
Claim 3
Dependent Claim
43 words
The battery set forth in claim 1 wherein said terminal posts have threaded center holes and said cap has an internal stud depending from the top wall thereof for engaging a center hole of a respective terminal post to retain the cap thereon.
Claim 4
Dependent Claim
32 words
The battery set forth in claim 2 wherein said stud is tapered to engage said threaded center hole with increasing interlocking engagement as the cap is pressed deeper onto said post connector.
Claim 5
Dependent Claim
79 words
The battery set forth in claim 2 wherein one end portion of said cap has a circular internal rib on the top wall thereof and depending therefrom for engaging the external threads of a respective terminal post, and wherein the top wall of said end portion within said circular rib has a diaphragm thickness permitting the wall to be readily fractured to enable a threaded tap connection to be made into the center hole of the respective terminal post.
Claim 6
Dependent Claim
129 words
The battery set forth in claim 1 wherein said terminal posts have threaded center holes and said end portions of said cap are cylindrically shaped and one end portion has a depending tapered stud for engaging the threaded center hole of one terminal post of the battery and the other end portion has a depending circular rib for engaging the exterior threads of the upper end portion of the next adjacent post both in response to pressing the cap downwardly onto the post connector, and wherein the top wall of said other cylindrical end portion within said circular rib has a diaphragm thickness permitting the same to be fractured to provide access for a screw-thread engagement of a connector tap into the center hole of the respective terminal post.
