Description

CABLE MOUNTING CLAMPS Field of Invention This description refers in general to cable mounting clamps, such as for mounting cables in cabinets. Background of the Invention Secure cable management during installation is essential in various environments. One such environment is fiber optic cabling, particularly in office environments. In these settings, fiber optic distribution boxes are used to manage fiber optic cable distribution. A box typically houses one or more fiber trays, each containing one or more cassettes. Within a cassette, an incoming fiber can be spliced, split, or otherwise modified, and outgoing fibers can be connected to the cassette and the incoming fibers to provide fiber optic connections within the office environment. The incoming cables containing the incoming fibers must be secured to the boxes to ensure safe and reliable connections. Current cable assembly techniques require the use of cable ties, self-adhesive fasteners, hose clamps, support clamps, etc. In many cases, the assembly performance with these devices is inferior to that of bQCfrnn / eznz / e / YiAi Ref. 345510 is desirable, and / or the ability to remove and replace these devices to relocate or adjust the associated cable is limited. Furthermore, while some quick-release solutions exist, these require an additional mounting plate that must be attached inside the enclosure. In addition, currently available mounting solutions do not alleviate torsional or bending stresses on the associated cables. This is particularly concerning when multiple mounting points are required. For example, in some cases, it may be necessary to divide large cables into smaller subassemblies. Both the larger cable and the subassemblies may need to be mounted and secured, thus requiring multiple mounting assemblies in different locations. Therefore, it can be difficult to provide secure mounting at all necessary locations without incurring torsional or bending stress problems. Therefore, improved cable mounting clamps are desirable. For example, it would be advantageous to have cable mounting clamps that can be easily and efficiently disassembled and reassembled in their respective environments, such as in electrical boxes. Furthermore, cable mounting clamps that include features to relieve torsional or bending stress on the cables would be beneficial. Brief Description of the Invention The aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through the practice of the invention. According to one embodiment, a cable mounting clamp is provided. The cable mounting clamp can be provided for mounting a cable to a surface. The cable mounting clamp includes a detachable base attachable to the surface. The base includes an outer body that defines an inner channel and a support ramp disposed within the inner channel, the inner channel extending along a longitudinal axis. The cable mounting clamp further includes a roller tube disposed within the inner channel and movably mounted on the support ramp; the roller tube is displaceable along the longitudinal axis relative to the support ramp. According to another embodiment, a cable assembly is provided. The cable assembly can be surface-mounted. The cable assembly includes a cable and a cable mounting clamp. The cable mounting clamp includes a detachable base that attaches to the surface. The base includes an outer body that defines an inner channel and a support ramp disposed within the inner channel, the inner channel extending along a longitudinal axis. The cable mounting clamp further includes a roller tube disposed within the inner channel and movably mounted on the support ramp. The roller tube is offset along the longitudinal axis relative to the support ramp. The cable is inserted through the roller tube and extends through the inner channel, such that the cable moves with the roller tube along the longitudinal axis. These and other features, aspects, and advantages of the present invention will be better understood with reference to the following description and the appended claims.

Detailed Description of the Invention The embodiments of the invention will now be discussed in detail, one or more examples of which are illustrated in the figures. Each example is provided by way of explanation of the invention, not to limit it. In fact, it will be evident to those skilled in the art that various modifications and variations of the present invention may be made without departing from the scope or spirit of the invention. For example, features illustrated or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover modifications and variations that fall within the scope of the appended claims and their equivalents. Referring now to FIG. 1, one embodiment of a fiber optic distribution box 10 is provided. Fiber optic distribution boxes 10 are generally used to manage fiber optic distribution, typically in office environments. The box 10 includes one or more walls 12, as shown, which define an interior 14 of the box. Within the box, one or more trays 16 can be housed. Each tray 16 can contain one or more cassettes 18. In general, an incoming fiber optic cable comprising a plurality of optical fibers may enter the interior 14 of the box 10 through a rear opening 20 defined by the walls 12. The optical fibers of the incoming fiber optic cable may extend from the cable inside 14. These optical fibers may be routed through the incoming fiber optic cable. These optical fibers may be routed to one or more of the cassettes 18, and spliced, split, etc. within the cassettes 18. The outgoing optical fibers may also be routed to one or more of the cassettes 18, and spliced, split, etc. within the cassettes 18. The outgoing optical fibers may also be directed to the cassettes 18 and connected to the incoming optical fibers by splicing, splitting, etc.These outgoing optical fibers can be directed from cassettes 18, and can exit from inside box 10 through a front opening 22 of box 10. The incoming fiber optic cable must be secured to box 10 to facilitate safe and reliable connections of the incoming optical fibers and to prevent the risk of breaking or damaging them. Accordingly, this description is intended for cable assemblies 50 that can be surface-mounted, such as the walls 12 of boxes 10, as described herein. More specifically, a cable assembly 50 according to the present description includes a cable 52 and one or more cable mounting clamps 54. The cable mounting clamp(s) 54 securely and detachably mount the cable 52 to an associated surface, such as, in exemplary embodiments, a wall 12 of a box 10. Such a secure and detachable mount is a direct mount, with direct contact between the cable 52 and the wall 12. This secure and detachable mount is a direct mount, with direct contact between the clamp and the surface (such as the wall 12), thereby eliminating the need to install additional mounting plates, etc. (as in the box 10). The cable mounting clamps 54 according to the present description advantageously facilitate the efficient assembly and disassembly of the cables 52, and furthermore, advantageously facilitate the relief of torsional or bending stresses in the cables 52.Cable mounting clamps 54, as described herein, are particularly advantageous when multiple mounting locations are required for a cable 52 (and / or smaller furred subassemblies thereof). The use of such cable mounting clamps 54 can significantly reduce problems of cable torsional stress or bending, and can also advantageously improve ease of assembly by providing greater tolerances for the cable mounting clamp 54 locations relative to the others. Referring now to Figures 2 to 15, several embodiments of cable assemblies 50 and cable mounting clamps 54 are provided according to the present description. In general, a cable mounting clamp 54 according to the present description may include a base 100 and a roller tube 104. In some embodiments, as illustrated in Figures 1-5, 8-9, and 11, a cable mounting clamp 54 may further include a cap 102. In other embodiments, as illustrated in Figures 12 to 15, no cap is required. The base 100 can generally be removably attached to a surface (such as a wall 12) to securely and removably mount the clamp 54 to the surface. The roller tube 104 can generally be mounted on the base 100, such as positioned between the base 100 and the cover 102 and / or detachably attached to the base 100.The roller tube 104 can be advantageously moved along an axis of the clamp 54 relative to the base 100, and can facilitate the movement of a cable 52 arranged therein. Furthermore, in some embodiments, the roller tube 104 can be rotated about the axis of the clamp 54, and can facilitate the rotation of a cable 52 arranged therein. The cable 52 can extend through the roller tube 104 and between the base 100 and the cover 102, and can be advantageously moved (and, optionally, rotated) relative to the base 100 with the roller tube 104. The base 100 generally includes an outer body 110 that defines an inner channel 112. The inner channel 112 extends along an axis 56 of the clamp 54. In exemplary embodiments, the axis 56 is a longitudinal axis 56 of the clamp 54. A support ramp 114, which may be or include an inner surface of the base 110, may be disposed within the inner channel 112 and partially define it. The support ramp 114 may have an arcuate shape around the axis 56, and thus, for example, be an arcuate surface as shown. The support ramp 114 may, in some embodiments, include an internal central surface 115, as illustrated in FIGS. 5, 12, and 13. Furthermore, in exemplary embodiments, the support ramp 114 may include first and second rails 116 and 118, respectively. Rails 116 and 118 may extend from the ramp 114 into the inner channel 112 and be spaced apart from each other along axis 56, acting as edges of the support ramp 114. For example, in some embodiments as illustrated in FIGS. 5, 12, and 13, rails 116, 118 can extend from the central inner surface 115 and therefore each can form a step at the intersection with the central inner surface 115. Alternatively, in some embodiments, as illustrated in FIGS.14 and 15, it is not necessary to provide a central interior surface 115, and instead a gap 119 can be defined between rails 116, 118. The base 100 may further include one or more tabs 120 and one or more fasteners 122. The tabs 120 generally position the base 100 on a surface (such as a wall 12) for a secure connection to it. The tabs 120 generally position the base 100 on a surface (such as a wall 12) for a secure connection to it, and the fasteners 122 releasably connect the base 100 (and therefore the clamp 54) to the surface (such as the wall 12). For example, each tab 120 may be removably insertable into an opening 60, which may, for example, be defined in a lance or a fastener, as discussed herein, of the surface. Each closure 122 can be releasably connected to the surface (such as the wall 12). Referring, for example, to FIGS. 4, 5, 8, 9, and 11, in some embodiments the base 100 includes a plurality (such as two as shown) of tabs 120 and a latch 122 that is separate from the tabs 120. In these embodiments the tabs 120 are positioned inside the base 100 and aligned along axis 56. In these embodiments, the tabs 120 are placed inside the base 100, and are aligned along axis 56. The latch 122 is a lever that includes a tab 120 and a latch 122. The latch 122 is a lever that includes a handle 130, a pivot point 132, and a contact face 134. The pivot point 132 is disposed on the top of the latch 122. The pivot point 132 is arranged between handle 130 and contact face 134, such that contact face 134 is opposite handle 130 in relation to pivot point 132. bQCfrnn / eznz / e / YiAi To mount the base 100 (and therefore the clamp 54) to a surface (such as a wall 12), the tabs 120 can be inserted through openings 60, which, as illustrated, can be defined in protrusions 62 formed from the surface. The contact face 134 can come into contact with one of the protrusions 62, thereby removably locking the base 100 (and therefore the clamp 54) in place, mounted to the surface. Such a locking position is illustrated, for example, in the figures. 8 and 11. To remove the base 100, the handle 130 can be pressed by a user, and this force can cause the contact face 134 to rotate around the pivot point 132 in such a way that the contact face 134 no longer makes contact with the spear 62. Such an unlocked position is illustrated, for example, in FIGS 8 and 11. Such an unlocked position is illustrated, for example, in FIG. 9.This lack of contact then allows the user to slide the tabs 120 from inside the openings 60, thereby removing the base 100 from being mounted on the surface. It should be understood that the present description is not limited to the base 100 components described above for the removable connection of the base 100 (and by extension, the clamp 54) to a surface (such as a wall 12). Rather, any suitable component that bQCfrnn / eznz / e / YiAi can provide for such a detachable connection is within the scope and spirit of the present description. Additional exemplary embodiments are provided in, for example, U.S. Patent Application Serial No. 15 / 862,225, the description of which is incorporated herein by reference in its entirety. Referring again to FIGS. 2 to 15, and as discussed earlier, a clamp 54 further includes a roller tube 104 and, in some embodiments, a cap 102. As illustrated in FIGS. 1-5, 8-9, and 11, the cap 102 can generally be connected to (and, when assembled, connected to) the base 100 to further define the inner channel 112 between them. In exemplary embodiments, the cap 102 may have an inner surface that is arcuate about the axis 56, and may therefore, for example, be an arcuate cap 102 as shown. In other embodiments, as illustrated in FIGS. 12 to 15, no cover may be used. For example, the support ramp 114 may include a central ramp portion 220, which may include portions of the central inner surface 115 or gap 119 and / or the rails 116, 118, as shown. The central ramp portion 220 may be included in embodiments where cover 102 is used or not used. However, in embodiments where a lid is not used, the support ramp 114 may further include opposing cantilever wings 222, each one of which extends from the central ramp portion 220. Each wing 222 may include opposing cantilever wings 222, each of which extends from the central ramp portion 220. Each wing 222 may include cantilevered portions of the central inner surface 115 or gap 119 and / or rails 116, 118, as shown.The wings 222 can generally extend above the central ramp portion 220 and can continue the arched shape of the support ramp 114, and can further define the inner channel 112. In exemplary embodiments, the wings 222 can be strongly skewed to selectively secure the roller tube 104 within the support ramp 114. For example, to mount the roller tube 104 on the support ramp 114, the roller tube 104 can be moved in a transverse direction and through the cantilevered ends 224 of the wings 222 within the inner channel 112. As the roller tube 104 moves in such a direction, it can come into contact with the wings 222 (such as their ends 224) and cause the wings 222 to flex outward, allowing the roller tube 104 to pass through. By being strongly skewed, the roller tube 104 can be moved in a transverse direction. Being heavily skewed, the 222 wings can return to their original position after the roller tube 104 has passed, so that the roller tube 104 is secured inside.Roller tube 104 can be removed in a similar manner. In some embodiments, clips 226 may be provided at the ends 224 of the wings 222, such as at the ends of the rails 116, 118. The clips 226 may provide additional security for the roller tube 104 when it is arranged within the support ramp 114. As shown in FIGS. 2-5, 8-9, and 11-15, the roller tube 104 can be placed inside (and, when assembled, arranged inside) the inner channel 112. Furthermore, the roller tube 104 can be movable while mounted on the support ramp 114, as in the exemplary embodiments. Additionally, the roller tube 104 can be movable while mounted on the support ramp 114, as in exemplary embodiments, and can be displaced along axis 56 relative to the support ramp 114. For example, the roller tube 104 can be movable along axis 56 relative to the support ramp. 114. For example, the roller tube 104 can be placed in the inner channel 112 such that the roller tube 104 extends along axis 56. Furthermore, the roller tube 104 can be in contact with the support ramp 114. The displacement along axis 56 can be relative to both the base 100 and the cap 102 (if used). For example, as discussed, the support ramp bQCfrnn / eznz / e / YiAi 114 may include first and second rails 116 and 118, respectively. In some embodiments, as shown in FIGS. 3, 5-9, and 12-15, the roller tube 104 may include a single external flange 180, which may be an annular flange as shown. The single external flange 180 may, for example, be positioned generally at a longitudinal center point (e.g., along axis 56). When only a single outer flange 180 is used, the roller tube 104 can be displaced in such a way that the single outer flange 180 can float between and selectively contact one of the first rail 116 or the second rail 118. For example, the roller tube 104 can slide along axis 56 in one direction until flange 180 makes contact with the first rail 116, and it can slide along axis 56 in the opposite direction until flange 180 makes contact with the second rail 118.Such arrangement of the outer flange 180 floating between the rails 116, 118 also advantageously reduces or prevents the risk of the roller tube 104 becoming disengaged from the base 100. In other embodiments, as illustrated in FIGS. 10 and 11, the roller tube 104 may include a plurality of external flanges 180, each of which may be an annular flange as shown. The external flanges 180 may, for example, be spaced apart from each other along the axis 56. Furthermore, in some embodiments as shown, the cap 102 bQCfrnn / eznz / e / YiAi may be used, and one or more grooves 182 (each of which may be an annular groove) may be defined on an inner surface of the cap 102. The roller tube 104 may be movable, so that a different external flange 180 may be in selective contact with each of the first rail 116 and the second rail 118 at various positions along the axis 56.Furthermore, in the exemplary embodiments when using the cap 102, the roller tube 104 can be slidable such that each of the plurality of grooves 182 can selectively accommodate one or more of the plurality of external flanges 180. Consequently, in several different positions of the roller tube 104 along the axis 56, a different external flange 180 can be in contact with each of the rails 116 and 118, and, if a cap 102 is used, a different external flange 180 can be accommodated in each groove 182, or the groove 182 can be empty, depending on the position of the roller tube 104 along the axis 56. In other exemplary embodiments, the roller tube 104 can be rotatably mounted on the support ramp 114 and rotatable about axis 56 (e.g., relative to the support ramp 114). For example, the roller tube 104 can be positioned in the inner channel 112 such that the roller tube 104 extends along axis 56. Furthermore, the roller tube 104 can be in contact with the support ramp 114. The rotation about axis 56 can be relative to both the base 100 and the cap 102 (if used). Referring again generally to FIGS. 1-15, in some embodiments, the roller tube 104 may include a center portion 190, a first end portion 192, and a second end portion 194. The first and second end portions 192, 194 extend in opposite directions from the center portion 190, such as in opposite directions along the axis 56. In some embodiments, the outer flange(s) 180 may be arranged on the center portion 190. In some embodiments, the first and second end portions 192, 194 may include one or more ribs 196, which may be annular ribs as shown. In addition, in some embodiments, the clamp 54 may include one or more heat-shrink tubes 200. Each heat-shrink tube 200 may be connected to the roller tube 104. For example, in some embodiments as shown, one heat-shrink tube 200 may be connected to and extend from the first terminal portion 192, and one heat-shrink tube 200 may be connected to and extend from the second terminal portion 194. In some embodiments, the ribs 196 may contact the heat-shrink tube(s) 200 and help maintain the position of the heat-shrink tube(s) 200 by preventing the heat-shrink tube(s) 200 from slipping off the roller tube 104 (such as the terminal portions). 192, 194 of the same). As discussed, cable assemblies 50 according to the present description include a cable 52 and one or more cable mounting clamps 54. The clamps 54 may be user-installed on a cable 52 or may be factory-installed on the cable 52. In the exemplary embodiments shown, the cable 52 is an optical fiber cable 52 comprising a plurality of optical fibers 70 arranged within an outer sheath 72. Mounting a clamp 54 to a cable 52 can be accomplished by means of a clamp 54. Mounting a clamp 54 on a surface can, in exemplary embodiments, further mount the associated cable assembly 50 and the cable 52 thereof, thereby efficiently, securely, and removably positioning the cable 52 on the surface. When installed, a cable 52 can be inserted through a roller tube 104. Additionally, in some embodiments as shown, the cable 52 can be inserted through the heat-shrink tube(s) 200 that is connected to the roller tube 104, such that the heat-shrink tube(s) 200 is also connected to the cable 52. In these embodiments, the heat-shrink tube(s) 200 can be shrunk over the cable 52 and the roller tube 104. Because the roller tube 104 is arranged in the inner channel 112, the cable 52 can extend further through the inner channel 112, such as along the axis 56.The cable 52 can generally be fixed relative to the roller tube 104, as in some embodiments due to contact by the heat-shrink tube(s) 200 and / or epoxy or other suitable binder disposed between the cable 52 and the roller tube 104, and can therefore generally be non-movable relative to the roller tube 104. However, advantageously, the cable 52 can be displaced with the roller tube 104 along the longitudinal axis 56 and, in some embodiments, rotatable with the roller tube 104 along the longitudinal axis 56. This written description uses examples to describe the invention, including the best way, and also to enable anyone skilled in the art to practice the invention, including making and using any device or system and performing any embodied method. The patentable scope of the invention is defined by the claims and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims. It is hereby stated that, as of this date, the best method known to the applicant for putting the aforementioned invention into practice is the one that is clear from the present description of the invention.
