Abstract: A method and assembly for protecting a device connected to a wiring harness is disclosed. The assembly includes a protective shield having a bore for receiving the device and a positioning device. An elongated wiring harness extends from the device being protected and through the bore of the protective shield. The positioning device is formed having a band that surrounds a central space. At least one flexible, resilient finger extends radially inwardly from the band into the central space. At least one of the fingers forcibly engages the harness sleeve to maintain the positioning device and the protective shield in a predetermined protection position along the harness sleeve at least partially surrounding the device being protected.

Abstract: An assembly for protecting a sensor connected to a wiring harness is disclosed. The assembly includes a heat shield having a bore for receiving the sensor. An elongated harness sleeve extends outwardly from the sensor and through the bore of the heat shield, the harness sleeve surrounding the wiring harness. A positioning device for holding the heat shield at a predetermined position along the harness sleeve engages both the harness sleeve and the heat shield. The positioning device is formed from an elongated band that surrounds a central space. A plurality of flexible, resilient fingers are positioned on the band and extend inwardly into the central space. The fingers forcibly engage the harness sleeve to hold the device and the heat shield with which it is engaged in a predetermined position along the harness sleeve surrounding the sensor.

Abstract: A heat shield is disclosed having a first layer with a reflective surface, a second, heat fusible layer, a third insulating and reinforcing layer, and a fourth layer formed of pressure sensitive adhesive. The edges of the layers align with one another to form a common perimeter to which heat and pressure are applied to fuse the heat fusible layer to the other layers and bond the layers to one another. The heat fusible layer forms a seal on the perimeter that prevents the diffusion of fluids between the layers.
