Abstract

This invention is an alternative to using a series of sheet metal individual contacts to transmit operating functions from a radio to a peripheral device. This is achieved by using a single molded elastomeric con- nector which carries fine, gold-plated metal conduc- tom arranged inside the dielectric material as shown in fig. 1. The connection is achieved in the z-axis only, and by using silicone as the carrying material it becomes an anisotropic conductor. This function is similar to W series elastomeric connectors already in use in the electronics industry.

MOLDED ELASTOMERIC CONNECTOR

  This invention is an alternative to using a series of sheet metal individual contacts to transmit operating functions from a radio to a peripheral device. This is achieved by using a single molded elastomeric con- nector which carries fine, gold-plated metal conduc- tom arranged inside the dielectric material as shown in fig. 1. The connection is achieved in the z-axis only, and by using silicone as the carrying material it becomes an anisotropic conductor. This function is similar to W series elastomeric connectors already in use in the electronics industry.

  The uniqueness of this molded connector is that it places the metal wires at predetermined locations within the silicone pad to match the locations of the mating contacts. The wires are placed inside the molded domes and the ends protrude slightly beyond the surface of the silicone material, as shown in fig. 2. The purpose for using molded domes is to ensure that the wires will go through the plastic bezel of the device, nesting the conductor within the bezel to hold it in place and to facilitate a proper alignment between

the interface of the radio and the peripheral device. During accessory operation, the molded connector is compressed behveen the radio contacts for accessories and the matching pads on the accessory circuit board, as depicted in fig. 3. This compression forces the wires to make co...
