Abstract

An easily assembled, waterproof pin interconnect l- is shown in a cutaway side view of Figure 1. For con- venience of explanation, interconnect 10 is described in conjunction with a radio housing. Interconnect 10 com- prises an insert molded pin plate (for convenience 12 pins are used in this description) 12, a carbon pad array 14, and a universal connect flex 16.

EFFICIENTLY ASSEMBLED PIN ARRAY INTERCONNECT

by Loon Wan Chong

   An easily assembled, waterproof pin interconnect l- is shown in a cutaway side view of Figure 1. For con- venience of explanation, interconnect 10 is described in conjunction with a radio housing. Interconnect 10 com- prises an insert molded pin plate (for convenience 12 pins are used in this description) 12, a carbon pad array 14, and a universal connect flex 16.

  As shown, universal connector flex 16 is generally mounted on the inner surface of the radio housing. One end extends through an opening 18 of the housing and is secured to the wall of a recess 20 of the housing. The contacts of flex 16 in the recess align with the pin pat- tern in both carbon pad array 14 and pin plate 12. Car- bon pad array 14 is then placed into recess 20 abutting against flex 16 so that the pads on array 14 contact the contacts of flex 16. Pin plate 12 is then snapped into place against array 14 thus securing array 14 tightly against the radio housing.

  Carbon pad array 14 is made of a compressible sili- con rubber formed about the carbon pads in the desired pattern. Therefore, when pin plate 12 is snapped against array 14, the rubber silicon compresses against the radio housing resulting in a waterproof seal. ?

  Pin plate 12, shown with array 14 in an isometric view in Figure 2, utilizes a conventional snap-fit means to snap into place in the radio housing....
