Abstract
A noise suppressor for permanent engagement over a cable comprises first and second case halves which are connected to each other by a hinge. At least one female latch tab is mounted to the first case half near an interior surface of the first case half and a male latch tab is mounted on an interior surface of the second case half. With the first and second case halves closed over a cable, the male and female latch tabs are locked to each other and are inaccessible from outside the case. The case may not be opened except by destroying the case. End walls of the case portions have recesses for passage of the cable therethrough and each case portion contains a suppressor core having a passage for receiving the cable.
Claims12
A noise suppressor for permanent engagement over a cable, comprising:
- a first case portion with an interior surface, said first case portion having opposite end walls and at least one side wall;
- a second case portion with an interior surface, said second case portion having opposite end walls and at least one side wall;
- said first and second case portions having mating surfaces which are engagable with each other in a closed position over a cable and with said interior surfaces inaccessible from outside said case portions;
- a female latch lab connected to said first case portion, said female latch tab having a locking surface;
- a male latch tab connected to said second case portion, said male latch tab having a locking surface which, with said case portions in said closed position, engages said locking surface of said female tab for locking said case portions in said closed position, said male and female latch tabs, in said closed position of said case portion, being located adjacent said interior surfaces of said first and second case portions so that said male and female latch tabs are inaccessible from outside said case portions;
- each end wall of each case portion having a cable recess therein which, with said case portions in the closed position form ports in the end walls for receiving a cable therethrough;
- mounting means in each case portion for retaining a suppressor core portion in each case portion;
- a suppressor core portion mounted in each case portion, each core portion having a cable passage, said passages receiving a cable therein when said case portions are in the closed position;
- and
- a plurality of resilient fingers connected to each end wall of each case and extending into each respective cable recess, each of said fingers being inclined outwardly with respect to an interior of each respective case portion so that movement of said caw portions into the closed position engages said fingers onto a cable for engaging the cable and deforming said fingers outwardly with respect to the interior of said case portions of resist relative movement between said case portions and the cable in opposite axial directions along the cable, said male latch tab being mounted on the interior surface of said second case portion on said at least one side wall, said female latch tab extending outwardly from said at least one side wall of said first case portion, adjacent the interior surface of said first case portion, said locking surface being positioned in an opening through said female latch tab, each finger having inner and outer surfaces which are both inclined outwardly with respect to an interior of each respective case portion, each of said fingers being substantially triangular with a truncated apex for defining an opening in each portion with said case portions in the closed position, at least one finger in each cable recess being at a different position with respect to at least one other finger in said cable recess along an axis extending between said cable recesses of one of said case portions.
