Abstract
Abstract An electrical connector is provided for an electrode having a headed stud thereon in which a slot is provided between electrical contact plates mounted on the connector. The headed stud of the electrode fits within this slot and a slidable locking bar having a cam surface thereon is moved to a locking position wherein the headed stud is forced into a narrowed portion of the slot and is locked in contact with the electrical contact means.

Claim 1
Independent Claim
210 words
In combination, an electrode including a stud having an enlarged head thereon, an electrical connector comprising a base plate, a slot in said base plate, a slidable locking element disposed in said slot, a cam surface disposed on said locking element, a recess in said base extending normally with respect to said slot, a pair of electrical contact elements, one of said electrical contact elements being fixed to said base plate on each side of said recess in said base plate whereby edge surfaces of said contact elements are in spaced relation to receive the electrode stud therebetween, an enlarged spacing portion between the contact elements to receive the head of the stud and adjacent thereto a reduced spacing portion between the contact elements of insufficient width to pass the head of the stud therebetween whereby when the electrode and connector are to be attached the headed stud is placed within the recess within the enlarged spacing portion between the contact element and the locking element is moved to bring the cam surface into engagement with the headed stud to force the headed stud to a position within the recess within the reduced spacing portion between the contact elements and to maintain the headed stud in a locked position therein.
Claim 2
Dependent Claim
