DESCRIPTION
Reference will now be made in detail to the preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Whenever possible, like reference numbers will be used to refer to like components or parts.
FIGS. 2 and 3 show different views of a preferred embodiment of a device 20 for receiving a subassembly, such as, for example, a furcation plug or a furcation adaptor, assigned to an optical fibre cable and for fastening the subassembly received on the device 20 to a mounting, such as, for example, a wall of a distribution panel or distribution cabinet, via the device.
The device 20 according to FIGS. 2, 3 has a bar-shaped basic body 21 with a topside 22 and with an underside 23. On the topside 22 of the bar-shaped basic body 21, a guide element 24 is formed which is designed to receive a subassembly, such as a furcation plug or a furcation adaptor, assigned to an optical fibre cable. Such a subassembly can be pushed into the guide element 24 in the direction of the arrow 25.
At mutually opposite ends of the bar-shaped basic body 21, anchoring elements 26 and 27 are formed, via which the device 20 can be fastened to a mounting, in particular a wall of a distribution panel or distribution cabinet.
The device 20 can be fastened to a mounting in such a way that the anchoring elements 26, 27 can be introduced in a barb-like manner into recesses of the mountings and thus project into the recesses of the mounting. The anchoring element 27 positioned at the front end of the bar-shaped basic body 23, as seen in the push-in direction 25, is formed as part of an element 28 having U-shaped cross section.
The element 28 being U-shaped is designed in such a way that a closed portion 29 of the latter is formed on the underside 23 of the bar-shaped basic body 21 or projects with respect to the underside 23 of the bar-shaped basic body 21. When the device 20 together with a subassembly received on the latter and assigned to the optical fibre cable, is to be fastened to a mounting, the element 28 being U-shaped engages with the closed portion 29 into a recess of the mounting. When a force is exerted on the element 28 in the push-in direction 25 the element 28 is subjected to a deformation in a way that the bar-shaped body 21 ultimately arches and the anchoring elements 26, 27 of the latter are clamped in the region of the recesses of the mountings. There is then no risk that the anchoring elements 26, 27 jump out of the recesses of the mountings inadvertently and the device 20 comes loose from the mounting inadvertently.
The guide element 24 of the device 20 comprises a bottom wall 30 formed by said bar-shaped basic body 21 and two opposite side walls 31, 32 running perpendicular to said bottom wall 21. Said walls 30, 31 and 32 of the guide element 24 define an interior 33 of the guide element 24. A subassembly, such as a furcation plug or a furcation adaptor, assigned to an optical fibre cable can be pushed into the interior 33 of guide element 24 in the push-in direction 25.
The guide element 24 for receiving the subassembly comprises at least two protrusions 34 forming latching elements which engage with shoulders or recesses formed in the subassembly to be received by the guide element 24 when the subassembly is pushed into said guide element 24.
FIGS. 4 and 5 both show the device 20 together with a subassembly, namely a furcation plug 36, received by the device 20. The protrusions 34 forming said latching elements which engage with shoulders 37 formed in the furcation plug 36.
Said protrusions 34 forming said latching elements are assigned to the opposite side walls 31, 32 of the guide element 24 in a way that they extend into said interior 33 of said guide element 24 so that they engage into said shoulders or recesses formed in side walls of the subassembly to be received by the interior of said guide element 24.
The protrusions 34 forming the latching elements run in parallel to said bar-shaped basic body 21, whereby the distance d (see FIG. 2) between the protrusions 34 assigned to the opposite side walls 31, 32 of the guide element 24 is decreasing as seen in the push-in direction 25 of the subassembly into the interior of said guide element 24. At the rear end of the basic body 21, as seen in the push-on direction 25, the distance d between the protrusions 34 is larger than at the front end of the basic body 21. The protrusions 34 from a lead-in taper helping to start the insertion of the subassembly in the device 20. In the shown embodiment, the distance d between the protrusions 34 decreases only in a portion of the protrusions 34, namely in a rear end portion, as seen in the push-on direction 25, in which the protrusions 34 from said lead-in taper. The width w (see FIG. 2) of said protrusions 34 assigned to said opposite side walls 31, 32 is increasing as seen in the push-in direction 25 of the subassembly into the interior of said guide element 25. Said increase of the width w of the protrusions 34 corresponds to said decrease of the distance d between the protrusions 34.
The thickness t (see FIG. 2) of the protrusions 34 assigned to said opposite side walls 31, 32 is decreasing toward the interior 33 of the guide element 24 as seen in a direction 35 running perpendicular to the push-in direction 25 of the subassembly into the interior 33 of said guide element 24.
When a subassembly, such as a furcation plug or a furcation adaptor, assigned to an optical fibre cable is inserted or pushed in the interior 33 of the guide element 24 in the push-in direction 25, the protrusions 34 forming the latching elements flex outwardly to receive the subassembly and then the protrusions 34 spring back and engage with the shoulders or recesses formed in the side walls of the subassembly in order to secure the subassembly within the device 20. The protrusions 34 are resiliently attached cantilever arms. With an increased insertion of the subassembly into the interior 33 of the guide element 24 the clamping force provided by protrusions 34 having the distance d, the width w and the thickness t to the subassembly is increasing. This allows an easy, durable and safe installation of the subassembly to the device 20.
