PRESENTATION ON CONNECTORS
INTRODUCTION
CONNECTORS ARE U.S.B OR SLOTS ON THE BACK OR
FRONT SIDE FO THE CABINET OR COMPUTER OR
ANY OTHER ELECTRONIC DEVICE
THESE ARE USED TO CONNECT ONE DEVICE TO
ANOTHER VIA WIRES

CONNECTORS
The part of a cable that plugs into a part or interface to connect
one device to another.
Most connectors are either male (containing one or more exposed
pins) or female(containing sockets in which the male
connector can be inserted).
A connector may be temporary, as for portable equipment, or
may be a permanent electrical joint between two wires or
devices.
There are hundreds of types of electrical connectors.
In computing, an electrical connector can also be known as
physical interface.

Connectors may refer to:-
8P8C connectors
D-subminiature connectors
USB connectors
Power connectors
Radio frequency connectors
Audio & Video connectors
Plug and socket connectors

8P8C Connector
8P8C is short for "eight positions, eight
conductors", and so an 8P8C modular connector
(plug or jack).
The 8P8C modular plugs and jacks look very similar to the plugs
and jacks used for FCC's registered jack RJ45 variants.
It neither uses all eight conductors (but only two of them for
wires plus two for shorting a programming resistor) nor does it
fit into 8P8C.
The connector is probably most famous for its use in Ethernet
and widely used on CAT5 cables.

D-subminiature connectors:-
The D-subminiature electrical connector is commonly used for the
RS 232 serial port on modems and IBM compatible computers.
The D-subminiature connector is used in many different
applications, for computers, telecommunications, and test and
measurement instruments.
A few examples are monitors (MGA, CGA, EGA), the
Commodore 64, MSX, Apple II, Amiga and Atari joysticks and
mice, and game consoles such as Atari, Sega and Amiga.

USB Connector
The Universal Serial Bus is a serial bus standard to interface devices, founded
in 1996. There are several types of USB connectors, and some have been added
as the specification has progressed.
The most commonly used is the (male) series "A" plug on peripherals, when
the cable is fixed to the peripheral.
If there is no cable fixed to the peripheral, the peripheral always needs to have a
USB "B" socket. In this case a USB "A" plug to a USB "B" plug cable would
be needed.
USB "A" sockets are always used on the host PC and the USB "B" sockets on
the peripherals. It is a 4-pin connector, surrounded by a shield.

USB
CONNECTORS
The Type A plug typically connects a cable to a desktop or laptop
computer. The end is a wide, flat rectangle.
The Type B plug generally goes into a for larger, typically
stationary devices such as a printer or MIDI keyboard.
Mini-USB and micro-USB is most often used to a portable device
such as a camera or digital audio player. The end looks like a wide
grin.

USB CONNECTORS
A USB system has an asymmetric design, consisting of a host, a multitude
of downstream USB ports, and multiple peripheral devices connected in a
tiered-star topology.
Additional USB hubs may be included in the tiers, allowing branching into
a tree structure, subject to a limit of 5 levels of tiers.
USB host may have multiple host controllers and each host controller may
provide one or more USB ports.
Up to 127 devices, including the hub devices, may be connected to a single
host controller

DIFFERENT TYPES OF USB CONNECTORS
This type of connector was designed to connect with mobile
devices. This one can be used without a computer and it can
be used with most mobiles.

DIFFERENT TYPES OF USB CONNECTORS
This type is known as the host connector and it is also
sometimes referred to as the downstream connector.
This is the one that you usually plug into the ports on
your computer’s USB port or into a USB hub. It's
usually rectangular in shape.

DIFFERENT TYPES OF USB CONNECTORS
This connector is mainly used for the different devices
that can be plugged into a port.
This one is also known as the upstream connector.
It is used to attaches directly to the end of a device
(that be a digital camera, a printer, a mouse or
keyboard, etc). A Type B connector is usually box
shaped.

DIFFERENT TYPES OF USB CONNECTORS
This connector was designed when the "USB creators" found
out the original connector for USB 2.0 ports was too big for
certain devices such as a PDA or a cell phone.
So, in the end, this one was created for those who wanted to
take advantage of the USB PC connectivity that is available
with these smaller devices

Power Connector
A power connector is an electrical connector designed to
carry a significant amount of electrical power, usually as DC
or low-frequency AC.
Some types of RF connector may also carry large amounts of
power, but are considered as a separate category.
Connectors carrying small amounts of power are known as
signal connectors

POWER CONNECTOR
A power connector is an electrical connector designed to carry a significant
amount of electrical power, usually as DC or low-frequency AC.
LOVELY PROFESSIONAL UNIVERSITY
DC Connector
A DC connector is an electrical connector for supplying direct current
(DC) power. DC connectors are poorly standardized, compared to
domestic AC power plugs and sockets.
DC plug is a common name used for one common type of cylindrical
two-conductor plug available in a range of sizes and used to power small
pieces of electronic equipment.

R.F CONNECTOR
An RF connector is an electrical connector designed to work
at radio frequencies in the multi-megahertz range.
LOVELY PROFESSIONAL UNIVERSITY
Radio Frequency Connector
RF connectors are typically used with coaxial cables and
are designed to maintain the shielding that the coaxial
design offers.
Mechanically they provide a fastening mechanism (
thread, bayonet, braces, push pull) and springs for a low
ohmic electric contact and allowing above 1000
reconnects and reducing the insertion force.
Research activity in the area of radio-frequency (RF)
circuit design has surged in the last decade for
inexpensive, high data rate wireless transceivers.

Optical fibers connectors
• An optical fiber connector
terminates the end of an
optical fiber, and enables
quicker connection and
disconnection.

Audio and video connector
Audio connectors and video connectors are electrical connectors for
carrying an audio signal or video signal, either in an analog or digital
format.
Audio connectors are electrical connectors designed and used for
audio frequencies. They can be analogue or digital.
Video connectors carry only video signals.

Plug and socket connectors:-
A male plug made by Amphenol
Plug and socket connectors are usually made up of a male plug and a female
socket.
Plugs generally have one or more pins or prongs that are inserted into openings
in the mating socket.
The connection between the mating metal parts must be sufficiently tight to
make a good electrical connection and complete the circuit.
