Abstract
Abstract A battery terminal post receives a split connector cap of compatible metal and the cap is firmly clamped to one end of a battery cable. A housing element for the battery terminal post and connector cap is sealed around the post in a fluid-tight manner. A threaded clamping or pressure sleeve is received in a threaded bore of the housing element and exerts pressure on a rear face of the connector cap. The cap and interior of the housing element are configured to cause firm clamping of the split cap on the battery terminal post in response to the pressure exerted by said sleeve.

Claim 3
Dependent Claim
232 words
A connector and housing for a storage battery terminal post comprising an electrically conducting connector cap for attachment to a battery terminal post, said connector cap having a through bore to receive said terminal post and having an arcuate forward end, the arcuate forward end having a slot communicating with said through bore, said connector cap having a rearward extension adapted for connection with a storage battery cable, said connector cap having a substantially flat rear end face surrounding said extension in a substantially semi-circular arc and said rear end face lying in a plane substantially parallel to the axis of said through bore, a non-conducting housing element for said connector cap and terminal post including a main chamber to receive the connector cap and having a bottom wall opening to receive said post, said main chamber having an arcuate forward wall engageable with said arcuate forward end of the connector cap, said housing element having a rearward screw-threaded sleeve extension, and a screw-threaded pressure sleeve adapted to be coupled with said screw-threaded extension and having a forward end face lying in a plane parallel to said flat rear end face and abutting the same fully around said semi-circular arc in a region opposite to said terminal post, whereby tightening of said pressure sleeve relative to the housing element will force said connector cap into firm gripping engagement with said terminal post.
Claim 4
Dependent Claim
232 words
A connector and housing for a storage battery terminal post comprising an electrically conducting connector cap for attachment to a battery terminal post, said connector cap having a through bore to receive said terminal post and having an arcuate forward end, the arcuate forward end having a slot communicating with said through bore, said connector cap having a rearward extension adapted for connection with a storage battery cable, said connector cap having a substantially flat rear end face surrounding said extension in a substantially semi-circular arc and said rear end face lying in a plane substantially parallel to the axis of said through bore, a non-conducting housing element for said connector cap and terminal post including a main chamber to receive the connector cap and having a bottom wall opening to receive said post, said main chamber having an arcuate forward wall engageable with said arcuate forward end of the connector cap, said housing element having a rearward screw-threaded sleeve extension, and a screw-threaded pressure sleeve adapted to be coupled with said screw-threaded extension and having a forward end face lying in a plane parallel to said flat rear end face and abutting the same fully around said semi-circular arc in a region opposite to said terminal post, whereby tightening of said pressure sleeve relative to the housing element will force said connector cap into firm gripping engagement with said terminal post.
