CLASS 439,	ELECTRICAL CONNECTORS
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This is the generic class for a pair of mated conductors comprising at least two electrically conducting elements which are interconnected to permit relative motion of such conducting elements during use without a break in electrical conductivity therebetween (see Subclass References to the Current Class, below).

Also, this is the generic class for a device constituting an electricity conducting contact between conductors of electricity; wherein the joint is of a type which may be readily made and broken, repeatedly by attachment and detachment of contact supporting structure on each conductor.

(1) Note. A soldered joint or joint formed by twisting together a pair of conductors and any of various other splices that is more or less permanent in nature is not generally provided for in this class. See the reference to Class 174 below for location of a device relating to such a splice joint. Also, see below for the scope of this class with regard to general utility and the lines with respect to other classes providing for a joint, per se.

(2) Note. Included under this class definition is a device known in the art as a contact plug, an outlet receptacle, a lamp socket, a vacuum tube socket, a connection block, a cable terminal, a cable joint, a binding post, a cube tap, a grounding strap, etc.

(3) Note. This class also includes a device specialized for use with an electrical connector and not elsewhere classifiable. Such a device may be, for example, any of certain types of mounting or supporting means, a locking device, a shield or cover, a strain relieving device, etc.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

COMBINATION OF AN ELECTRICAL CONNECTOR WITH ANOTHER DEVICE

With respect to a combination of an electrical connector with an art device, no absolutely uniform rule of classification can be set forth. Disposition of such combination depends on factors such as the nature of the combined art device, the manner in and extent to which such art device, per se, and in other combinations have been classified, the relationship of other classes to this class as regards superiority, and the manner in which the combination is claimed. Generally, the combination of an electrical connector with an art device is classifiable in the appropriate art class. Also, an electrical connector limited to arrangement or use with an art device is generally classified in the appropriate art class. Two or more different electrical devices combined with an electrical connector will be found in the class providing for the combined electrical devices, even though they are broadly recited.

CONNECTOR, PER SE, ELSEWHERE CLASSIFIED

Since any mechanical joint, coupling or connector, when made of metal or other material capable of conducting an electrical current may be said to "electrically" connect, only such structure as are specially designed for and/or disclosed for electrical use have been placed in this class (Class 439).

A patent disclosing a connector having utility both as an electrical connector and as a mechanical coupling wherein the claims do not limit the connector function as an electrical connector is classified in the appropriate class providing for the mechanical joint.

A patent claiming a limitation of structure, composition, or arrangement utility in an electrical installation and not generally applicable to a class providing for the mechanical joint is classified in this class (Class 439). Reference to electrical insulation features is considered to establish electrical utility in an electrical installation.

As stated in the Class Definition, (2) Note, above, the connector of this class (Class 439) is generally of the type wherein an electrical joint can be readily made or broken and reused. Generally an electrical joint of a more permanent nature (e.g., molded, soldered, twisted or crimped connection) is not provided for in this class.

See the notes at the beginning of this section for the general rule of classification. However, certain specific types of electrical connectors are excepted from the general rule, as follows:

Electrode Joints - See Class 313 class definition, Lines With Other Classes, "Electrodes and Shields with Joints Therebetween" for the line between Class 403 and this class (439) with respect to electrode joints.

Rail Bonds - See Class 238, subclass 14.05, (6) Note for the line between the various classes with respect to rail bonds.

METHOD OR APPARATUS FOR MANUFACTURING OR APPLYING AN ELECTRICAL CONNECTOR

A patent including a claim to an electrical connector structure of this class (439) and another claim to a process or an apparatus for manufacture of such an electrical connector is originally classified in this class (439) with a mandatory cross-reference in the appropriate manufacturing class. See References to Other Classes, below.

Note however, that such a device may be found in this class (Class 439) if the coupling of the housings is ancillary to making electrical connection. An electrical connector of class (Class 439) can be distinguished from a circuit maker or breaker of Class 200 in that an electrical connector is physically separated from a distinct mating connector each time the circuit is broken; whereas, a circuit maker or breaker comprises a "permanent" assemblage of parts including both a movable contact and its mating contact wherein there is a positive physical connection between the contacts such that a contact is restricted to move with respect to the mating contact along a prescribed path each time the circuit maker or breaker operates. (1) Note. An electrical connector, per se, may include movable contacts and be in this class (438), the class of electrical connectors. For example, search Class 439, for an electrical connector with a selectable circuit wherein no details of the circuit structure are set forth; for an electrical connector with a coupling separator; for an electrical connector detachable from a mating connector by snap or quick-break action; for a connector with a contact moved laterally into engagement with a mating contact in a "zero insertion force device"; for an electrical connector with coupling movement-actuating means or retaining means in addition to the contact, especially for a retaining means with distinct movement-actuating means to move a coupling part axially; and for an electrical connector with guiding means for mating of a coupling part.

SECTION V - GLOSSARY

Terms or phrases used in definitions either repeatedly or in a special or limited sense are set forth below with the meaning each is to have in this class. For economy of space, an asterisk (*) following a word or phrase indicates that reference should be made to this glossary for the specific meaning thereof.

CABLE

An elongated, flexible assembly of two or more elongated conductors intended to transmit electricity from one end to the other, the conductors being electrically insulated from one another but physically held together in association with one another.

(1) Note. The two or more physically associated but mutually insulated conductors are usually further enclosed within an outer protective or insulating covering or sheath.

(2) Note. A stranded, wire-type conductor is considered to be a single conductor.

CONDUCTOR

A member intended to transmit electricity from one portion or end thereof to another portion or end thereof, and to which electricity-transmitting member the electricity-conducting part of an electrical connector is intended to be electrically joined or attached.

(1) Note. A conductor may include such diverse members as an electrical cable, a wire (either stranded or solid), a grounding plate, an inductive shield, a bus bar, or an electricity-transmitting path formed of a conductive film deposited on an insulating plate or panel, etc.

CONNECTOR

A device for forming an electricity-conducting joint between conductors of electricity, wherein the device either (1) consists solely of an electricity-conducting element having a contact surface for forming the joint or (2) comprises an assembly which includes an electricity-conducting element having a contact surface for forming the joint and further includes any structure necessary to support, carry, or encase the conductive element; and wherein the joint is of a type which may be readily made and broken, repeatedly, either (a) by engaging or disengaging the conductive element or (b) by engaging or disengaging the conductive element with a conductor.

CONTACT

An electricity-conducting component of an electrical connector, including a contact surface intended to form a readily made and broken electricity-conducting joint by directly engaging either a conductor or a corresponding surface of a cooperating joint-forming conductive component, so as to permit the passage of electricity through the joint from one component to the other.

COUPLING PART

An electrical connector comprising a contact and additional supporting structure specially adapted to mate with a specific complementary electrical connector.

(1) Note. A "specific complementary electrical connector" is also a "coupling part" in this class, but may be referred to as a "mating part" in order to distinguish it from the first mentioned coupling part. Also, such a "counterpart" and the complementary contact thereof may be referred to as the "counter-contact".

(2) Note. A relatively short, generally stationary rodlike connector is not considered to be a "coupling part" even though it otherwise meets the limitations of this definition, because such structure has not been so considered in the past. Similarly, a connector for interfitting with such a short rodlike connector is not considered to be a "coupling part". Such a connector may commonly be used on an automobile electrical energy battery. Note further that this restriction does not apply to a generally fixed socket and a cooperating short rodlike connector.

(3) Note. A bare wire (or cable) making electrical contact is not a coupling part; nor is a connector for making direct engagement with such a wire. Also, neither a threaded stud nor a ring for fitting over such a stud is considered to be a coupling part.

MATING PART

A coupling part for electrically connecting with a specific coupling part. Actually a coupling part and a mating part are structurally the same, the distinct terminology is used in this class as an aid to expression.

PRINTED CIRCUIT BOARD

A relatively thin, flat insulating sheet, panel, or plate having two or more circuit elements or conductors deposited, adhered, or otherwise formed on a planar surface thereof, the circuit elements or conductors being electrically insulated from one another or being, during use, at electrical potentials different from one another.

(1) Note. The art of this subclass (and those subclasses intended hereunder) is somewhat different from that of the remainder of the class in that the indented function of the art of this area is to permit relative movement of two electrically connected members; whereas, the other areas of the class are to provide for disconnection of two parts which do not move with respect to each other during electricity transmitting use. (2) Note. The design and intent of the connector of this subclass is to allow movement of the two members during use as distinguished from adjustment made incidental to a coupling or uncoupling as in screwing a plug into a socket is not included herein. Also, separable couplings which due to the physical disposition of the contacts (e.g., concentric contacts) theoretically might allow relative movement of the members but are excluded from this subclass unless there is a specific disclosure that such relative movement during use is intended.

(1) Note. A second or intermediate conductor may be pivotally connected to the first conductor for movement about a first axis with respect thereto and may be pivotally connected to a third conductor for movement with respect thereto about a second axis transverse to the first axis to allow resultant "universal" movement. (2) Note. The pivotal movement of this subclass is controlled; e.g., a pliable connecting rod allowing similar movement is not included herein. (3) Note.
