Premolded suppressor sleeve

A preformed noise suppressor for engagement over a cable, comprising:

• a cylindrical ring shaped core having a core passage extending from one end of the core, to an opposite end thereof, the core passage being adapted to receive a cable extending through the core, the core being made of electrical noise absorbing material;
• a one piece cylindrical preformed sleeve of resilient insulating material covering the core, the sleeve extending beyond both ends of the core and having a sleeve passage to accommodating a cable extending through the core passage;
• and
• securing means formed as one piece with the sleeve and engageable with a cable extending through the core for securing the sleeve at a selected position along the cable;
• the sleeve comprising a main cylindrical portion extending around the core and having an inside diameter defining part of the sleeve passage, a cylindrical projection having a smaller inside and outside diameter than the main portion, extending outwardly from the main portion, the sleeve passage extending through the projection, the securing means comprising the projection for frictionally engaging a cable extending through the core, and a circular thick wall portion of the sleeve extending on an opposite side of the main portion from the projection, the thick wall portion having a thicker wall thickness than the projection and a smaller inside and outside diameter than the main portion, the projection being longer than the thick wall portion.
