Electrical connectors do not usually contain

hazardous materials. They contain conduct-

ing and non-conducting materials and can

be divided into two groups.

a) Printed circuit types and low cost audio

types which employ all plastic insulators and

casings.

b) Rugged, Fire Barrier and High Reliability

types with metal casings and either natural

rubber, synthetic rubber, plastic or glass

insulating materials. Contact materials vary

with type of connector and also application

and are usually manufactured from either:

Copper, copper alloys, nickel, alumel,

chromel or steel. In special applications,

other alloys may be specified.

g.. Heat

dissipation is greater at maximum resistance

in a circuit. Hot spots may occur when resist-

ance is raised locally by damage, e.g. cracked

or deformed contacts, broken strands of

wire. Local overheating may also result from

the use of the incorrect application tools or

from poor quality soldering or slack screw

terminals. Overheating may occur if the rat-

ings in the product Data Sheet/Catalog are

exceeded and can cause breakdown of insu-

lation and hence electric shock. If heating is

allowed to continue it intensifies by further

increasing the local resistance through loss

of temper of spring contacts, formation of

oxide film on contacts and wires and leakage

currents through carbonization of insulation

and tracking paths. Fire can then result in

the presence of combustible materials and

this may release noxious fumes. Overheating

may not be visually apparent. Burns may

result from touching overheated compo-

nents.

Care must be taken to avoid damage

to any component parts of electrical connec-

tors during installation and use. Although

there are normally no sharp edges, care

must be taken when handling certain com-

ponents to avoid injury to fingers. Electrical

connectors may be damaged in transit to the

customers, and damage may result in cre-

ation of hazards. Products should therefore

be examined prior to installation/use and

rejected if found to be damaged.

Incineration of certain materials may release

noxious or even toxic fumes.

PLLIIC

TIIO

Connectors with exposed contacts should

not be selected for use on the current supply

side of an electrical circuit, because an elec-

tric shock could result from touching

exposed contacts on an unmated connector.

Voltages in excess of 30 V ac or 42.5 V dc are

potentially hazardous and care should be

taken to ensure that such voltages cannot be

transmitted in any way to exposed metal

parts of the connector body. The connector

and wiring should be checked, before mak-

ing live, to have no damage to metal parts or

insulators, no solder blobs, loose strands,

conducting lubricants, swarf, or any other

undesired conducting particles. Circuit

resistance and continuity check should be

made to make certain that there are no high

resistance joints or spurious conducting

paths. Always use the correct application

tools as specified in the Data Sheet/Catalog.

Do not permit untrained personnel to wire,

assemble or tamper with connectors. For

operation voltage please see appropriate

national regulations.
