Berg connector
Berg connector is a brand of electrical connector used in computer hardware. Berg connectors are manufactured by Berg Electronics Corporation of St. Louis, Missouri, now part of Amphenol.
Overview
Berg connectors have a pitch of. Pins are square, and usually come as single or double row connectors.Many types of Berg connectors exist. Some of the more familiar ones used in IBM PC compatibles are:
- the four-pin polarized Berg connectors used to connect 3½-inch floppy disk drive units to the power [supply unit], usually referred to as simply a "floppy power connector", but often also referred to as LP4. This connector has a pitch.
- the two-pin Berg connectors used to connect the front panel lights, turbo switch, and reset button to the motherboard.
- the two-pin Berg connectors used as jumpers for motherboard configuration.
Floppy drive power connector
The power connector on the 3½-inch floppy drive, informally known as "the Berg connector", is 2.50 mm pitch.The power cable from the ATX power supply consists of 20 AWG wire to a 4-pin female connector. The plastic connector housing is most often white, as shown, but black is also common. Other colours are rarer. The part numbers used for the female contact pins depends on the detailed design, the surface coating and the form of supply. Example part numbers are any of TE Connectivity / AMP 170204-* or 170262-*, where * is 1 or 2 or 4.
The male PCB connector on the 3½-inch floppy drive is normally a polarized right-angle male header, which is a TE Connectivity / AMP 171826-4, the straight model is AMP 171825-4.
The shape of the connector housing makes it very easy to determine the pin number allocations by visual inspection.
