  • Figures 4a through 4f illustrate additional forms of retention features 318 suitable for coupling the ratcheting retainer 102 with the component 110, including a W-type fastener 110a, a pin clip 110b, a box-prong fastener 110c (illustrated as a 2-legged box-prong fastener), a specialty clip assembly HOd (e.g., a CenterLokTM fastener, which is available from Deltar®), a clip assembly with four retaining legs 1 lOe, and a clip assembly with two snap-engaging seats 1 lOf.
  • the pin clip 110b can be provided to serve as a reusable fastener having a low insertion value that may be used with a grommet.
  • the pin clip 110b includes a retention feature having a pin head positioned at a distal end of the shank 314.
  • the pin clip 110b may be configured, for example, as a single position fastener or a multi-position fastener.
  • the clip assembly with four retaining legs 1 lOe, which is illustrated in Figure 4e as a cross sectional view, is further described in connection with commonly-owned U.S. Patent No. 10,385,901 to Jeffrey J. Steltz.

  • Figures 5a through 5f illustrate an example process for loading and installing the ratcheting retainer 102.
  • Figure 5a illustrates an initial step of assembly where, as illustrated, the ratcheting retainer 102 is in a relaxed, open position (i.e., the strap portion 204 is not yet inserted into the ring portion 206).
  • the first object 114a approaches the gap 502 between the distal end of the strap portion 204 and the ring portion 206 in the direction indicated by arrow 504.

Abstract

Un dispositif de retenue à cliquet (102) est divulgué, permettant de fixer un ou plusieurs objets (114a, 114b), tels que des faisceaux de fils, à un composant (110). Le dispositif de retenue à cliquet comprend un ensemble sangle à cliquet (104), un élément de fixation (106) et un attache-câble (108). L'ensemble sangle à cliquet, à diamètre réglable, circonscrit et fixe un premier objet (114a). L'élément de fixation est accouplé à l'ensemble sangle à cliquet et fixe le dispositif de retenue à cliquet au composant. L'attache-câble est accouplé à l'ensemble sangle à cliquet et fixe un second objet (114b) à l'ensemble sangle à cliquet.
