Abstract

PURPOSE:To prevent positional shift of cable by holding a cable in the holding space of a case enclosing a split ferrite core, temporarily stopping the cable by means of a stopper and a stop hook, stretching a tie-wrap tag and then hooking the ratchet thereof to a tie-wrap hook. CONSTITUTION:A fastening tie-wrap tag 7 having a ratchet 7a is suspended integrally from the side face of a rotary half case body 1b and a tie-wrap hook 8 to be hooked with the ratchet 7a of the tie-wrap tag 7 is provided integrally on the side face of a fixed half case body 1b. A cable 3 emitting spurious radio wave is then held in a holding space 4 provided between the fixed half case body 1a and the rotary half case body 1b of a split core case 1. A stop hook 6 is then pulled down and engaged with a stopper 5 thus temporarily stopping the cable 3. Thereafter, the tie-wrap tag 7 is stretched and the ratchet 7a thereof is hooked to the tie-wrap hook 8.

A tie wrap hook 8 for locking is integrally provided.

Fixed half case body 1 of the above split core case 1
The cable 3 emitting unnecessary radio waves is sandwiched in the sandwiching space 4 between the rotating half-case body 1b and the cable 3, and the cable 3 that is emitting unnecessary radio waves is pulled down to lock the cable 3 to the stopper 5 for temporary locking, and then the tie-wrap tag 7 Tense and that ratchet 7a
Secure it to the tie wrap hook 8. Note that the tip of the remaining tie wrap tag 7 may be removed. FIG. 2 is an enlarged perspective view of the main locking part. FIG. 6 is a perspective view of a modified example in which a plurality of tie-wrap tags 7 and tie-wrap hooks 8 are provided, and by doing so, it can be held even more firmly.

Example 2. FIG. 3 is a perspective view showing the whole of another ferrite split core case 1 according to the present invention, FIG. 4 is a side view showing the tied state, and FIG.
is a perspective view showing a bound state. The same parts and corresponding parts as in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted here.

In this embodiment, one end of the tie wrap tag 7 having a ratchet 7a is fixed to the outside of the cable insertion hole 4a of the split core case 1, and the ratchet 7a of the tie wrap tag 7 wound around the cable 3 is further fixed. A tie wrap hook 8 for locking is provided.

Fixed half case body 1 of the above split core case 1
The cable 3 emitting unnecessary radio waves is sandwiched in the sandwiching space 4 between the rotating half-case body 1b and the cable 3, and the cable 3 that is emitting unnecessary radio waves is pulled down to lock the cable 3 to the stopper 5 for temporary locking, and then the tie-wrap tag 7 is wound around the cable, and its ratchet 7a is permanently secured to the tie wrap hook 8.
