DETAILED DESECRIPTION

[0013] This disclosure relates to a MLT assembly including a cushioning component to provide an integrated compliant element, thus allowing for application across non-compliant bundles. With the rapid growth and global implementation of 5G infrastructure, there is a need to install data and antenna enclosures to both greenfield and brownfield vertically mounted poles. The MLT assembly including the cushioning component may, for example, now be used to secure such bundle components in the installation of the 5G infrastructure.

[0014] FIG. 1 shows the MLT assembly 100 in an assembled state according to an exemplary embodiment. The MLT assembly 100 includes a body 20 and a head assembly 30. The body 20 is an elongated strap member made from, for example, a metal, polymer, or other material with a sufficient tensile strength for bundling components. The head assembly 30 is made, for example, from a metal material. As shown in FIG. 2, the head assembly 30 includes a housing 31 shaped to hold one or more metal balls within an inner housing. The metal balls are configured to move bi-directionally with the tension and anti-tension movements, as described in more detail with reference to FIGS. 4A-4B.

[0015] The MLT assembly 100 also includes a cushioning component 40, where the cushioning component 40 is configured to fit over the head assembly 30. As shown in FIG. 2, the cushioning component 40 is a molded component that is molded to take on a shape (e.g., sleeve shape) that allows it to slide over the head assembly 30 in the direction A, and conform to the geometry of the head assembly 30 when attached. The cushioning component 40 is made from a flexible/pliable material such as a polymer, elastomer, or rubberized compound, where the selection of the material may be dependent on the compression required for the desired tensile strength, load, and/or environmental aspects relating to the installation scenario. A thickness of the cushioning component 40 (e.g., portion below the head assembly) may be directly proportional to a size of the body 20, or otherwise related to an intended application size of the bundle around which the MLT assembly 100 is intended to be secured around. In other embodiments, the thickness of the cushioning component 40 may be a predetermined thickness selected according to an intended application of the MLT assembly 100.

[0016] With the attachment of the cushioning component 40 to the head assembly 30 of the MLT assembly 100, the MLT assembly 100 may be applied to secure a non-compliant bundle and the cushioning component 40 will compress to provide the necessary compliance, allowing for the tension and anti-tensioning movements for locking the ball elements inside the housing 31 of the head assembly 30.

[0017] FIG. 3A shows a front perspective view of the cushioning component 40, showing a view of a front stop member 41. The front stop member 41 is included to assist in preventing the cushioning component 40 from sliding past a front portion of the head assembly 30 more than intended in an assembled position (e.g., assembled position shown in FIG. 1). FIG. 3B shows a back perspective view of the cushioning component 40, showing a view of a back stop member 42. The back stop member 42 is included to assist in preventing the cushioning component 40 from sliding past a back portion of the head assembly 30 more than intended in the assembled position.

[0018] FIG. 4A shows a side view of the MLT assembly 100 during an operation of the MLT assembly 100. When a front portion of the body 20f (i.e., portion of the body 20 that has been routed through the head assembly 30) is pulled in the tensioning movement, a tension is applied to the MLT assembly 100 as it secures around the exemplary bundle 50 (e.g., the bundle 50 may be representative of one or more cables, pipes, or other conduit components). During the tensioning movement of the front portion of the body 20f, the metal balls within the housing 31 are allowed to freely move inside the housing.

[0019] With the tension applied, the cushioning component 40 is compressed to conform, at least partially, around the bundle 50 as shown in FIG. 4B. The compression of the cushioning component 40 allows for further travel of the body 20 in the tensioning movement than if the cushioning component 40 was not present or if the cushioning component 40 was made from a more rigid material that did not allow for compression. Then with the release of the tension on the front portion of the body 20f, the cushioning component 40 is allowed to expand and thus provide an opposite tension for moving the body 20 in the anti-tensioning movement, which causes the metal balls within the housing 31 to adjustably abut against an inner surface of the housing 31 and results in the locking of the MLT assembly 100. Thus the release of the compression from the cushioning component 40 allows for enough anti-tension movement to engage the locking mechanism of the metal balls within the housing 31, while still keeping a tight and secure grip on the bundle 50.

[0020] According to alternative embodiments, the cushioning component 40 may be a molded component that slides directly onto the head assembly 30. The cushioning component 40 may also be overmolded directly onto the head assembly 30 or adhered to the bottom surface of the head assembly 30 using an adhesive or tape. In these alternative embodiments, the shape of the cushioning component 40 may take on the form of a pad of polymer, elastomer, or rubberized compound adhered to the bottom surface of the head assembly 30.

[0021] The MLT assembly 100 offers a quick, easy, and effective solution for securing bundles in a variety of environments that were not possible using other typical metal ball locking ties. The MLT assembly 100 provides a more efficient installation process that only requires a short compression and expansion to allow the metal ball locking mechanism of the MLT assembly 100 to travel from the tensioning position to the locking position while maintaining a secure grip on the bundle being secured.

[0022] Furthermore, while the particular embodiments described herein have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the teachings of the disclosure. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as limitation. The actual scope of the disclosure is intended to be defined in the following claims when viewed in their proper perspective.
