DEFINITION

Classification: 439/709

Insulating body having plural mutually insulated terminals or contacts (e.g.., terminal block):

(under subclass 625) Electrical connector wherein two or more current-carrying terminals, contacts,* conductor-securing means, or other metallic connectors are carried by an electrically insulating body in a relatively fixed, spaced-apart relationship with one another and in electrical insulation from one another.

(1) Note. A connector included in this and the indented subclasses differs from a plural-contact coupling part (as found in subclasses 626+) in that a connector included herein is neither adapted nor in any other way intended to be coupled or mated to a single complementary insulating body carrying plural mutually insulated contacts.

(2) Note. One common type of connector included herein (usually known as a terminal block or board) has a first means to receive and electrically interconnect separate wire-type conductors or separate wire-type conductor end terminals and has a second means to receive and electrically interconnect another set of separate wire-type conductors or another set of separate wire-type conductor end terminals; the said another set of conductors remaining, however, electrically insulated from the first set of conductors.

(3) Note. Any of the metallic connectors, terminals, or conductor securing means carried by a terminal block or board included herein may simply be in the form of a screw or nut securing means around which a wire-type conductor is intended to be wound, or it may be in the form of a clip for receiving a complementary wire-type conductor or wire-type conductor end terminal, but in every case the wire-type conductors received by such terminal block or board are physically separate elements.

(4) Note. Also included herein (particularly in subclasses 710 and 712+) is a single insulating body (commonly known as a "modular" terminal block or board) which usually has a single current-carrying bus or commoning bar having two or more electrically interconnected terminals, contacts, or conductor-securing means thereon. This "modular" terminal block or board is particularly adapted and intended to be separably joined or assembled with or more other terminal blocks or boards which are substantially identical in structure to the first said block or board, so that an assembly composed of any desired number of identical terminal blocks or boards may be built up. The resultant assembly is thus comprised of a composite insulating body carrying a plurality of mutually insulated terminals, contacts, or conductor-securing means.
