Cables Connector

One or more optical fibers enclosed, with strength members, in a protective covering is called Cables Connector.

From the signal point of view, a cable connector can be viewed as a short, rigid cable. The cable connector usually has the same impedance as the related cable and probably has a similar cutoff frequency although its dielectric may be different. High-quality cable connectors are usually gold or rhodium plated, with lower-quality cable connectors using nickel or tin plating. Silver is occasionally used in some high-end cable connectors due to its excellent conductivity, but it usually requires extra plating of another metal since silver readily oxidizes in the presence of air.

One increasing development has been the wider adoption of micro-miniature coaxial cable in the consumer electronics sector in recent years. Wire and cable companies such as Tyco, Sumitomo Electric, Hitachi Cable, Fujikura and LS Cable all manufacture these cables connector, which can be used in cellular phones.

DIN Connector

DIN is an abbreviation for Deutsches Institut für Normung, or German Institute for Standardization, which is a German manufacturing industry standards group. There exist DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector"). In the context of consumer electronics, the term "DIN connector" commonly refers to a member of a family of circular connectors that were initially standardized by DIN for analog audio signals. Some of these connectors have later also been used in analog video applications and for digital interfaces such as MIDI or the IBM PS/2 computer keyboard and mouse cables. The original DIN standards for these connectors are no longer in print and have been replaced with the equivalent international standard IEC 60130-9.

DIN connectors are round, with pins arranged in a circular pattern. This type of connector was used widely for PC keyboards, MIDI instruments, and other specialized equipment. Another type of DIN connector is the mini-DIN. As the name suggests, mini-DIN connectors are smaller in size than a regular DIN. They are still round, but with the pins arranged in horizontal rows rather than in a circular pattern. Mini-DIN connectors are used for S-video connections, PS/2 mouse & keyboards, and some other applications. DIN and mini-DIN connectors are both held in place by the friction of the connector body and by pins.

The mini-DIN connectors are a family of multi-pin Electrical connectors used in a variety of applications. Mini-DIN is similar to larger, older DIN connector. Mini-DIN connectors are 9.5 mm in diameter and come in seven patterns with any number of pins from three to nine. Each "flavor" is keyed in such a way that a plug with one pattern cannot be mated with any plug of another pattern.

5-pin Din
5-pin Din Male
5-pin Din Female
Used for older AT-style computer keyboards. The 5 pins are arranged in a circular order.

4-pin Mini Din
4-pin Mini Din Male
4-pin Mini Din Female
The 4-pin mini-DIN connector is most often used for S-video applications. Older Apple computers also used it with the ADB mouse & keyboard interface. There are 4 pins arranged in 2 rows, and a keying block to make certain that the plug cannot be improperly inserted. Note that the male 4-pin mini-DIN plug can be inserted into the 7-pin mini-DIN socket commonly found on laptop computers.

6-pin Mini Din
6-pin Mini Din Male
6-pin Mini Din Female
6-pin mini-DIN connectors are often called PS/2 connectors. This interface was first used on the IBM PS/2 personal computer, and it soon became the industry standard for connecting keyboards & mouses.

8-pin Mini Din
8-pin Mini Din Male
8-pin Mini Din Female
This connection was commonly used with the serial interface on older Apple computers. Nowadays, it can sometimes be found on portable video devices. The 8-pin Mini-DIN features three rows of pins.

Speaker Connector

Speaker Connector is a type of cable connector commonly used in pro audio systems for connecting loudspeakers to amplifiers. A similar connector is available for mains power called the PowerCon.

Speaker Connector features a quick-locking system with options for soldered or screw-type solderless for easy repair in the field. Line connectors only mate with (male) panel connectors (not with other line connectors) and typically a cable will have identical connectors at both ends. If it is needed to join cables a coupler is used (which basically consists of two panel connectors mounted on the ends of a plastic tube).

The Speaker connector is an alternative to 1/4", two-pole twist lock, and XLR connectors for loudspeakers. Many consider Speaker to be superior to 1/4" jack because of its ability to lock the plug to the socket preventing the speaker from becoming disconnected by movement or other forces. Additionally, it provides a fully-insulated connection to equipment, eliminating electrical shock risks associated with high power audio amplifiers. Many European countries do not allow 1/4" or banana-type output connections on power amplifiers for this reason.

Another advantage is its unambiguous use in speaker cables: with jack and XLR connections, there's the risk of using low-current shielded microphone or instrument cables in a high-current speaker application. The main disadvantages are cost and dependence on a single manufaturer.

Speaker connectors are available in two-, four- and eight-pole configurations. The two-pole line connector will mate with the four-pole panel connector, connecting to +1 and -1; but the reverse combination will not work. The eight-pole connector is physically larger to accommodate the extra poles. The four-pole connector is the most common at least from the availability of ready-made leads, as it allows for things like Bi-amping (two of the four connections for the higher-frequency signal, with the other two for the lower-frequency signal) without two separate cables.
