A cable connector is a widely used accessory in the field of computers and electronics. Besides the two fields mentioned above, the said accessory also has a major role to play in many other applications. Some commonly used cable and connector confirmations are available commercially and off the shelf, as ready to use cable assemblies.     
It is well worth knowing, that a cable connector, besides doing its primary job of connecting external cables to any sort of allied equipment, also possesses the potential to be fitted internally to certain specific equipment, if and when required. This is done to facilitate the removal of certain trouble shooting sub assemblies such as PCBs etc for repairs, without disturbing the main set up.
There are many permutations to a cable connector, and a connector which is contrived to be attached to the end of a cable, is termed as a ‘Free connector’. This breed of connector contains some aspect of strain relief to hold the cable mechanically, so that tautness in the cable is not transmitted to electrical joints inside the cable connector. Another kind of connector is the ‘Fixed Connector’. This variety of connector, which falls within the ambit of a cable connector, is designed for mounting on a PCB or panel.
A vast majority of cable connectors are designed to be user friendly. In that, one should be able to easily disconnect and or reconnect the same, from any sort of electronic equipment etc, that it is being used in tandem with. The list of different cable connectors available today is near endless, and some of the products which form a part of this list include, the ‘SM10-240/50 cable connector’ from YUEQING SMICO of China, and the ‘20 pin Flat Cable Connector’ from SUNROM Technologies.
