DEFINITION

Classification: 439/757

With clamp-to-post joint separator:

(under subclass 754) Electrical connector having some positive means to break the joint between the battery terminal post and clamp connector by causing movement of the connector or a part thereof with respect to the terminal post.

(1) Note. In these connectors the coupling is not removed completely from the battery post, nor need it be even electrically separated therefrom. The joint separating means in these connectors is intended primarily to break a "frozen" joint to permit further separation of the parts by other means. A connector which has means for separating one coupling part of a coupling from another coupling part may be found in subclasses 152+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

152+, and see (1) Note above.

180, for a connector having means to separate contacts by a snap or quick-break action.

258, for a coupling part with a latching means and tether or explosive to unlatch from a mating part.

266+, for a coupling part having a handle or means to move a contact laterally to permit uncoupling.
