Connectors: A History of Their Technology?

dpbsmith asks: "It seems like a simple engineering problem--construct a device for easily and safely connecting several dozen wires at the same time--but the variety and creativity in their design over the years has been amazing, and, clearly there have been trends, fashions, and styles. In the fifties and sixties, virtually all connectors were roughly similar to the D-Sub design used for RS-232. A stiff, straight pin engaged a springy socket that contacted and bore against it on all sides. There were minor variations in shape and placement; the Amphenol Blue Ribbons (think Centronics), the connectors into which circuit boards engaged, but they were all variations on a theme. I was absolutely astounded the first time I saw a modular RJ-11 connector. Cheap, effective, and utterly unlike anything I'd ever seen before. Who invented these? Western Electric? Recently, we have the USB connector and the Firewire connector, obviously members of the same family (and a cheap-and-cheesy-seeming family it seems); on the other hand, my telephone and my digital camera have connectors that are very small and snap in with a positive lock that must be released with a squeeze, obviously yet another fundamentally different design. What do people know about the design, history, and engineering behind connectors over the years? Is it all hidden away, trade secrets of the connector companies, or is their a story that can be told?"

    I was six when i first heard of the term "male" and "female" connectors. Even though I keep pestering my dad about
    1) which one is male / female, and
    2) why they name it something stupid like that

    he just kept "umm... ahhh"-ing and never answered.

    I was like 17 when it finally dawned on me why they named it that way. ha! then it all made sense.

    moral of the story are:
    a) who says electrical engineers / connector designers are not perverted?
    b) to save yourself trouble, don't talk about male/femail connectors in front of little kids.

    It might be easier if we switched from 60Hz to something around 20kHz.

    You want to overclock the power lines?

    Your forgot one:
    • Human sex organs - 7. Nice, but it would be better if the male had it's own female connector slot and double-jointed-ness in the pin for the the times that male can't find an opposing connector.
