Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
216 words
A connector device for connecting batteries comprising: a pair of single-pole connectors each of which has an insertion hole for receiving a contact finger of a mating terminal, the insertion hole being formed in an electrical contacting portion provided at the front end of a wire terminal provided on a wire suitable for connecting to a battery post of a battery so that said insertion hole is located substantially perpendicular to the axis of the wire terminal, .said wire terminal and said electrical contacting portion being mounted in an insulating housing which comprises a cylindrical portion accommodating said wire terminal and a raised collar which is substantially perpendicular to said cylindrical portion, said raised collar surrounding said insertion hole for receiving the contact finger; a connector case body for accommodating the pair of single-pole connectors substantially in parallel to each other; and a case cover which may be engaged with said connector case body and further may be locked thereto, said case cover including a pair of said contact fingers which are inserted into said insertion holes so as to be electrically connected to said electrical contacting portions when said connector case body is closed by said case cover, said pair of contact fingers being electrically connected to each other by means of a short-circuit terminal.
Claim 2
Dependent Claim
216 words
A connector device for connecting batteries comprising: a pair of single-pole connectors each of which has an insertion hole for receiving a contact finger of a mating terminal, the insertion hole being formed in an electrical contacting portion provided at the front end of a wire terminal provided on a wire suitable for connecting to a battery post of a battery so that said insertion hole is located substantially perpendicular to the axis of the wire terminal, .said wire terminal and said electrical contacting portion being mounted in an insulating housing which comprises a cylindrical portion accommodating said wire terminal and a raised collar which is substantially perpendicular to said cylindrical portion, said raised collar surrounding said insertion hole for receiving the contact finger; a connector case body for accommodating the pair of single-pole connectors substantially in parallel to each other; and a case cover which may be engaged with said connector case body and further may be locked thereto, said case cover including a pair of said contact fingers which are inserted into said insertion holes so as to be electrically connected to said electrical contacting portions when said connector case body is closed by said case cover, said pair of contact fingers being electrically connected to each other by means of a short-circuit terminal.
Claim 3
Dependent Claim
46 words
