Insulation resistance - >1000 mega ohms RMC Connectors Withstanding voltage -– 1050 DC or AC peak The IDC connectors are usually found in PCs, low current circuit boards, telecoms devices etc. Thus the IDC connectors provide easy and highly reliable connection with a ribbon cable. It is actually a great advantage imagine how long it will take to strip all the separate wires in a thirty or forty wire ribbon cable. The following image might give you an idea about assembly of an IDC connector.įig. A crimping tool can be used for this purpose. The wires are inserted into the IDC connector and crimped carefully to ensure perfect connection. 11: Image showing sharpened blades in an IDC connector The IDC connector has selectively sharpened blade or blades each of them can pierce through the insulation of the corresponding wires in a cable.įig. 10: Image of Male and Female IDC connector Unlike other wire terminals there is no need to strip out the insulation of the wire before attaching it to the connector.įig. IDC connector is otherwise called referred to as Insulation Displacement Termination (IDT). Ribbon cable is also a kind of flat cable with many actual cables attached side by side forming a single flat wide and flexible cable. This connector is specifically designed to be used with ribbon type cables. Insulation Displacement Connector (IDC) is a connector which uses a method called insulation displacement to make the wires connected to the contacts of the connector perfectly. Withstanding voltage -– 150V AC/1 minuteĬontact resistance - 50m ohms IDC Connectors The FFC connectors find its application high end circuits, embedded system including mobile phones where this FFC connector is always used to connect the wires to the LCD screen. The SMD models are used in advanced board and most of them have very small mating cycles. The above image shows diagram of the bend and straight type FFC connectors in its through hole model and SMD models. 8: Image showing FFC through hole and FFC SMD connectors Similar to all other components, the FFC connectors are also available in through hole and SMD models.įig. Since FFC connectors are widely used in PCB, they can be considered as a component in the PCB design itself.

7: Image showing FFC connector connecting FFC to a PCB The following image shows a FFC cable connected to a circuit board using the FFC connector.įig. The FFC connectors are also referred to as Flat Panel Cable (FPC) connectors. 5: Image showing the FFC cables inserted into FFC connector All you need to do is to insert the FFC into the connector and press the lock down.įig. It has a lock like structure you can see it in the above image as a black plastic strip. Unlike other connectors there is no crimping or stripping required attaching the FFC to the connector. FFC connectors are specially designed connectors for connecting the FFC cables to the PCB. 3: Image of Flat Flexible Cables (FFC)įFCs are use in standard board design to carry data or signals from board to board or from one section of a board to other since 1970s. They are made of very flexible plastic with flat copper lines embedded between the plastic layersįig. Voltage rating - 300 V FFC Connectorsįlat Flexible Cables (FFC) is used in situations where there are a large number of wires to be connected between two boards or between two sections of a single board unit etc. The PCB Terminal Block as its name indicates finds its application in almost all kind of PCBs including microcontroller boards. Each wire has its entry slot into the connector. The wire is then safely fixed inside it by tighten down the screw. A small part of the insulation of the wire just enough to be fit into the slot is stripped out and can be inserted into the connector. The above image shows how wires can be connected to the PCB Terminal Block. 2: Image showing wires connected into PCB Terminal Block A PCB Terminal Block has at least two wire slots, and there are PCB Terminal Blocks available with more than 10 connection slots.įig. A single slot is normally used for connecting only a single wire, but one can easily connect multiple wires at also. One side of the PCB Terminal Block has slots available to insert wire into it and tighten by screws ensuring proper contact. They are little used for transferring signals. These connectors are used only for supply power to or from the PCB. PCB Terminal block is used to terminate the wire at the PCB. We will be discussing about the PCB Terminal Block, FFC connectors, IDC connectors and RMC connectors There are wide varieties of wire-to-board connectors available.

As the name indicates, these kinds of connectors are used to connect a wire or a bunch of wires to a circuit board.
