Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A method of producing a battery terminal connector comprising the steps: a. moulding a part circular bifurcate ring of a lead based alloy, said ring having an inner contact frusto conical surface, b. positioning said ring in an injection moulding die which comprises a pair of die parts, a slot extending across the die parts when closed, a pair of oppositely aligned lug forming inserts in the slot and guided for movement by the walls of the slot, c. moving said lug forming inserts towards one another, d. injecting a resin based plastics material into said die to mould an outer casing around said bifurcate ring and form lugs in said slot between the lug forming inserts, e. withdrawing the inserts away from one another, and, f. opening the die parts and removing the connector therefrom.

Claim 3
Dependent Claim
92 words
Method of producing a battery terminal connector according to claim 1 further comprising moulding a hollow tail to extend outwardly from the part circular bifurcate ring, removing the end of the insulation of an insulated wire cable to expose a length of cable, inserting the exposed length of wire into the hollow tail and clamping the tail over the wire, and then effecting steps (b), (c), (d), (e) and (f) of claim 1 to mould said outer casing over said bifurcate ring and, at the same time, over portion of said insulation.
Claim 4
Dependent Claim
