electrical connectors Electronic symbols for male-ended and
female-ended connectors     Properties of electrical
connectors[edit]  Electrical connectors are characterised by
their pinout and physical construction, size, contact
resistance, insulation between pins, ruggedness and resistance
to vibration, resistance to entry of water or other
contaminants, resistance to pressure, reliability, lifetime
(number of connect/disconnect operations before failure), and
ease of connecting and disconnecting.  They may be keyed to
prevent insertion in the wrong orientation, connecting the wrong
pins to each other, and have locking mechanisms to ensure that
they are fully inserted and cannot work loose or fall out. Some
connectors are designed such that certain pins make contact
before others when inserted, and break first on disconnection;
