Dielectric component with electrical connection

摘要

The dielectric component, for a laminated heater mat for an ice protection system for an aircraft, comprises a dielectric layer (50) comprising thermoplastic material or a stack of such layers with first and second main surfaces and a hole (505) extending between the first and second main surfaces. A first sprayed metal coating (501) comprises a first portion (503) deposited on the fist main surface (502) adjacent to the hole (505) and a second portion (5014) which projects into the hole. A second sprayed metal coating (5013) comprises a thud portion deposited on the second main surface (506) adjacent to the hole (505) and a fourth portion (5015) which projects into the hole (505). The second portion (5014) is overlapped by the fourth portion (5015) to form a continuous conductive path between the first main surface and the second main surface. This provides a cheap, neat and thin connection through the dielectric layer or the stack of dielectric layers.
