Clarksville, Ind. - Ranoda Electronics Inc. says its insulation displacement connector (IDC) for terminating discrete wires or multiconductor ribbon cables connects in 10 seconds.
On the bottom side of the circuit board, the IDC uses Ranoda's Electrically Encircled Compression (Eecom) connector technology to eliminate the need for female receptacles. A simple plastic assembly terminates discrete wires and ribbon cables of up to 40 wires on 0.05-inch centers to printed-circuit boards via plated through-holes, without the need for a second connector part, Ranoda said. This slashes parts count and assembly-time costs for a number of electronic products including home appliances, office equipment, industrial controls, telecommunications gear and automobiles, according to the company.
On the top side, a simple hand tool terminates a ribbon cable to its connector in just 10 seconds. On the bottom, another 5 seconds is required for mating the entire assembly to its circuit board, the company said. The cost of connecting ribbon cable to a circuit board thus involves one low-cost part and 15 seconds of labor.
In operation, the top side of the Eecom-IDC uses a V-shaped knife contact to terminate the ribbon cable. A hand tool or automated termination tool forces the wire into the wedge, displacing its insulation as it enters the gap. The wire strands force the jaws apart, making a secure connection on both sides of the wire, which is held captive by the IDC contact. The benefit is there is no need for wire preparation.
The IDC connection is said to withstand mechanical shock up to 50 g's in all three axes. Contact resistance is 10 milliohms or better. Contact voltage rating is 250 Vac minimum, per-line current rating is 1 amp and insulation resistance is specified at 500 Megohms minimum. Dielectric-withstanding voltage is 1,500 Vac for a minute. Contacts on both the top and the bottom are tin-lead plating over copper alloy. Mate-demate lifetime is rated at 500 cycles for the bottom Eecom pins.
Pricing for Ranoda's Eecom-IDC connectors is 3.5 cents per line in quantity. Delivery is quoted at two to three weeks ARO.
