A cable tie comprises a strap having a plurality of spaced parallel racks of teeth extending along the length thereof and a head for receiving the strap. A reinforcing median strip extends along the length of the strap between the racks of teeth to add material thickness, and mechanical strength to the strap. A bifurcated pawl is included in the head so that a separate pawl engages each rack of teeth. The teeth in each rack are in substantial, contiguous alignment. The teeth in the pawls are also in substantial, contiguous alignment for engaging the teeth of the strap. The median strip guides and directs the pawls as they ratchet over and come to rest in a locked position against said rocks of teeth.

Cable tie

A cable tie has a plurality of spaced parallel racks of teeth extending along the length thereof. A reinforcing median strip extends down the strap between the racks of teeth in order to add material thickness, and therefore a mechanical strength to the strap. The pawl is bifurcated so that a separate pawl engages each rack of teeth. The teeth in each rack are offset from each other so that no deep notch extends more than approximately half way across the strap at any given transverse location. The teeth in the pawls are offset in a similar manner.

A printed circuit board guide rail has one or more detents projecting far enough into the area traversed by the board to apply a horizontal holding and an antivibration pressure thereto. A notch window is formed in the part of the rail under the detent to give it a fixed-fixed suspended leaf spring quality for minimumizing vibration. The unnotched remainder of the rail enables a printed circuit board to slide freely thereover. The rail is arched to give vertical stability.
