Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the U.S. provisional application No. 63 / 397,949 filed on August 15, 2022, and all the invention contents of the related application are incorporated herein by reference in their entirety.

[0003] background

[0004] The present invention generally relates to cable connection tamper resistance. More particularly, the present invention relates to a system for tamper resistance of cable connections, such as terminal connectors on coaxial cables.

[0005] Sometimes, a provider's customers will disconnect a modem (or other device) from a wall connector and take the modem to the customer's next residence or other service location. The provider wants to discourage this practice by securing the modem to the wall connector. Conventional patch cords can be tightened and loosened by hand and / or can be tightened and loosened with a wrench.

[0006] It may be desirable to provide a system that increases the difficulty associated with disconnecting a cable from a connection. For example, it may be desirable to provide a connector that: snaps together but cannot be disassembled; is designed not to be engaged with a wrench; and allows tightening without the use of tools but is configured to be loosened using a tool, wherein the type of tool to be used is not readily apparent. Summary of the invention

[0007] Examples of the present invention provide a two-part security sleeve system that snaps together around a cable connector (e.g., a coaxial cable connector) allowing the connector to be tightened to a mating connector by hand, but cannot be removed from the mating connector unless a tool is used. For example, an Internet service provider provides a device (e.g., a modem) that is connected to a wall connector by a length of cable. Sometimes, the provider's customers disconnect the modem (or other device) from the wall connector and take the modem to the customer's next residence or other service location. The provider wants to prevent this practice by securing the modem to the wall connector.

[0008] An exemplary embodiment of the present invention includes two safety portions that are joined together from opposite ends of a connector and snap together to surround the connector. An inner portion or body has a hexagonal cutout that is sized to surround and engage a hexagonal nut of the connector. This engagement allows the connector to be tightened to a mating connector when the inner portion is rotated in a tightening direction (e.g., clockwise). In an embodiment, an outer portion or body has a plurality of recesses in an inner surface that are configured to engage a plurality of lobes on an outer surface of the inner portion when the outer portion is rotated in a tightening direction. In an embodiment, the lobes are located at the ends of the flexible fingers and are therefore structurally configured to bend inwardly (toward a central axis of the connector and safety sleeve) when subjected to an inward force generated by the lobes contacting the inner surface of the outer portion at various locations rather than the recesses. As the outer portion is rotated in a direction opposite to the tightening direction (the "loosening direction") (e.g., counterclockwise), the convex corners are pressed inwardly (through the interaction of the convex corners with the inner surface of the outer portion) so that the convex corners do not engage with the recesses, thereby allowing the outer portion to rotate relative to the inner portion. This relative rotation prevents the rotation applied to the outer portion from being transferred to the inner portion, which in turn prevents the connector from rotating and thus preventing the connector from disconnecting from the mating connector. In an embodiment, once the inner portion and the outer portion are snapped together, they cannot be separated from each other without damaging one or both parts or using special tools.

[0009] In an embodiment, the inner portion and the outer portion have a plurality of holes extending in a direction perpendicular to the central axis of the connector and offset from the central axis. In an embodiment, in order to enable the connector to be rotated in the loosening direction, a tool (e.g., a paper clip) is inserted into the hole. The tool engages a flat surface or other surface of, for example, a hexagonal nut of the connector so that the hexagonal nut is rotationally locked to the outer portion, and thus, the connector is rotated in the loosening direction. This allows the connector to be disconnected from the mating connector. Unless a knowledgeable user uses the tool, this embodiment prevents the connector from being disconnected from the mating connector.

The safety sleeve system may include: an inner portion that may be structurally configured to engage a tightening portion of a cable connector; and an outer portion that may be structurally configured to receive the inner portion.

[0050] Embodiments of the present invention provide a two-part security sleeve system that snaps together around a cable connector (e.g., a coaxial cable connector) allowing the connector to be tightened to a mating connector by hand, but cannot be removed (or easily removed) from the mating connector unless a tool is used, thereby preventing unauthorized disconnection of the connector. In embodiments, this provides a functional result of a tamper-resistant security sleeve system that prevents removal of the coaxial connector from a mating connector or port unless the user knows the removal process and the removal process uses a tool that is easily made from a household item (e.g., a paper clip).

[0051] Figure 1 An exemplary safety sleeve system 100 is shown attached to a coaxial cable connector, which is attached to a coaxial cable 10. In this example, the safety sleeve system 100 includes a second portion (eg, outer portion 200) and a first portion (eg, inner portion 300). Figure 2 FIG. 1 shows a safety sleeve system 100 whose components are separated, and shows a coaxial connector 60 and a coaxial cable 10. In this example, the coaxial cable 10 includes an outer jacket 20, a ground braid 30, a dielectric insulator 40, and a center conductor 50. The coaxial connector 60 has compression sections 64, 68 that are compressed when the coaxial connector 60 is attached to the coaxial cable 10 (e.g., Figure 3 and Figure 4), these compression sections slide relative to each other. In this example, the coaxial connector 60 has a hexagonal nut 62 including a protrusion 63. The hexagonal nut 62 also includes a thread 61, which is structurally configured to connect to a mating connector. The coaxial connector 60 has a rear body 68 at its rear end.

[0052] like Figure 2 and Figure 3 As shown, the outer portion 200 has a grip portion 210, which in this example is a plurality of flat areas that facilitate the user to rotate the outer portion 200. The outer portion 200 has a plurality of engagement protrusion engagement portions 240 protruding from the inner surface of the outer portion 200. In this example, the engagement protrusion engagement portions 240 are ledges that extend radially toward the central axis of the outer portion 200. The inner surface 220 of the outer portion 200 transitions outward to form an adjacent surface 230, thereby creating the engagement portion 240. The outer portion 200 also has a plurality of tool receiving holes 280, which will be discussed in detail below.

[0053] Figure 2 and Figure 3 An inner portion 300 is shown having a body 320 from which a plurality (in this case, three) of rotational engagement portions (e.g., rotational engagement fingers 340) and a plurality (in this case, three) of axial engagement fingers 330 extend. Each rotational engagement finger 340 has an inclined portion (e.g., a ramp 345 having a face 346 at one end of the ramp 345) at its end. The face 346 is structurally configured to engage with the engagement portion 240 of the outer portion 200 when the outer portion 200 is rotated in a tightening (in this case, clockwise) direction, so that the rotational movement of the outer portion 200 is transmitted to the inner portion 300. As described below, this clockwise rotation of the inner portion 300 is transmitted to the hexagonal nut 62 of the coaxial connector 60 to enable the coaxial connector 60 to be threadedly connected to a mating connector (e.g., a coaxial port). In this example, the inner portion 300 has a radially extending flange 310 that prevents the inner portion 300 from passing through the outer portion 200. In this example, the inner portion 300 is prevented from passing through the outer portion 200 by the rear surface 312 of the flange 310 contacting the ledge 222 on the outer portion 200 (see Figure 4 ). In this example, the inner portion 300 has a plurality of tool receiving holes 380, which will be discussed in detail below.

[0054] As mentioned above, Figure 3 1 shows the connector 60 in a compressed state, which is the state the connector 60 will be in when attached to the coaxial cable 10. It should be noted that while the coaxial cable 10 will be connected in this state, Figure 3 , the safety sleeve system is shown separated from the coaxial cable 10 to help illustrate the features of the safety sleeve system 100.

[0055] Figure 4 The safety sleeve system 100 is shown in an installed state on the coaxial connector 60. Figure 4 As shown, the inner portion 300 and the outer portion 200 are engaged with each other around the coaxial connector 60 . Figure 4 The inner part 300 is shown inserted into the outer part 200 so that the rear surface 312 of the flange 310 contacts the ledge 222 of the outer part 200. One or more of the axial engagement fingers 330 have an engagement protrusion 335 at their end. The engagement protrusion 335 has an engagement face 336 that extends radially outward toward the inner surface of the outer part 200. In an embodiment, in the embodiment shown in FIG. Figure 4 In the mounted state shown, one or more of the engagement surfaces 336 engage the ledge 250 on the inner surface 260 of the outer portion 200. Figure 4 In the mounted state shown, one or more of the engagement surfaces 336 are positioned further toward the rear of the outer portion 200 than the ledge 250 (in the embodiment shown in FIG. Figure 4 250) so that the engagement surface 336 does not contact the ledge 250, but limits the movement of the outer part 200 relative to the inner part 300 in the separation direction. In an embodiment, the interaction of the engagement surface 336 and the ledge 250 prevents the outer part 200 from separating from the inner part 300. In an embodiment, assembling the safety sleeve system 100 to the coaxial connector 60 includes (after connecting the coaxial connector 60 to the coaxial cable 10): sliding the outer part 200 on the inner part 300 so that one or more engagement surfaces 336 engage the ledge 250 and lock the outer part 300 to the inner part 200; and sliding the outer part 200 and the inner part 300 (engaged with each other) on the coaxial connector 60 from the front end (the end with the exposed center conductor 50) until the tightening part engagement portion (e.g., the inner face 301 of the inner part 300) engages the tightening portion (e.g., the outer surface of the hexagonal nut 62 of the coaxial connector 60). In an embodiment, the inner portion 300 is connected to the hex nut 62 by one or more interacting features such that the inner portion 300 cannot move axially relative to the hex nut 62. Figure 4 In the example shown, the inner portion 300 has a plurality (in this case, three) of ridges 390 that interact with one or more grooves 65 in the hexagonal nut 62 .

[0056] Figure 5 and Figure 6 The outer portion 200 is shown in more detail. Figure 7 and Figure 8 The inner portion 300 is shown in more detail. Figure 7 and Figure 8 A ramp 345 is shown that transitions from a larger end terminating at a face 346 to a smaller end 347. As described above, when the outer portion 200 is rotated in the tightening direction, the face 346 of the ramp 345 engages the engagement portion 240 of the outer portion 200. Because the face 301 of the body 320 of the inner portion 300 engages the protrusion 63 (or other portion of the hex nut 62), any rotation applied to the inner portion 300 is transferred to the hex nut 62 (and therefore to the threads 61). As a result, the rotation of the outer portion 200 in the tightening direction is transferred to the threads 61 and causes the coaxial connector 60 to be tightened onto the mating connector or port.

[0057] However, the structure of the inner part 300 and the outer part 200 prevents the transmission of rotation in the loosening direction. The ramp shape of the ramp 345 will not transmit the rotation in the loosening direction from the outer part 200 to the inner part 300 because there is no engagement portion for transmitting such rotation. After being installed on the coaxial connector 60, the rotation of the outer part 200 in the loosening direction will cause the inclined surface 220 (located on the inner surface of the outer part 200) to slide on the ramp 345 and push the ramp 345 radially inward (thereby pushing the axial engagement finger 330). Continued rotation of the outer part 200 will eventually cause the face 346 of the axial engagement finger 330 (on the inner surface of the outer part 200) to pass through the engagement portion 240 without engaging with the engagement portion 240. As a result, the rotation of the outer part 200 in the loosening direction will not be transmitted to the inner part 300, and therefore will not be transmitted to the hexagonal nut 62. In this manner, the safety sleeve system 100 inhibits or prevents the coaxial connector 60 from being removed from the mating connector or port except with the use of a tool, as will be described below.

[0058] Figures 9 to 12 4 shows how to use the tool 400 to remove the coaxial connector 60 from the mating connector or port. As described above, the outer portion 200 has a plurality of tool receiving holes 280 and the inner portion 300 has a plurality of tool receiving holes 380. Fig.11 As shown, the tool receiving hole 380 is adjacent to the side (or protrusion 63) of the hexagonal nut 62. The outer portion 200 can be rotated relative to the inner portion 300 so that the tool receiving hole 280 is aligned with the tool receiving hole 380, as shown in FIG. Fig.11 As shown. Fig.11 In the aligned position shown, tool 400 can be inserted into tool receiving hole 280 and tool receiving hole 380, as shown in FIG. Fig.12 As shown. Fig.12In the position shown, the straight portion 410 of the tool 400 contacts the hexagonal nut 62, causing the hexagonal nut 62 to rotate with the outer portion 200 in both the tightening direction and the loosening direction. As described above, without the tool 400 in place, rotating the outer portion 200 in the loosening direction will not rotate the hexagonal nut 62. As a result, Fig. 9 and Fig.12 Use of the tool 400 shown enables a user to remove (unscrew) the coaxial connector 60 from a mating connector or port while the safety sleeve system 100 is in place on the coaxial connector 60 .

[0059] Fig.10 The example of the tool 400 shown in the embodiment includes two straight portions 410, a center portion 430, and two corner portions 420 connecting the straight portions 410 to the center portion 420. This is just one example of a tool that can be used to rotationally fix the outer portion 200 to the hexagonal nut 62. Other embodiments include tools of different shapes, but include a portion similar to the straight portion 410, which is structurally configured to be received by the tool receiving holes 280, 380, thereby preventing the hexagonal nut 62 from rotating relative to the outer portion 200. An example of a tool according to an embodiment of the present invention is a common paper clip that is bent to form the straight portion 410. By configuring the inner portion 300 and the outer portion 200 as described above, the paper clip can be used as a tool that allows the hexagonal nut 62 to rotate in a loosening direction. This provides a functional result of an anti-tampering safety sleeve system that prevents the coaxial connector from being removed from a mating connector or port unless the user knows the removal process and the removal process uses a tool that is easily made from household items (e.g., a paper clip).

[0060] In an embodiment, when the ramp 345 is in its outermost position, the tool receiving hole 380 is aligned with the tool receiving hole 280. In other embodiments, when the ramp 345 is partially or completely pushed radially inward, the tool receiving hole 380 is aligned with the tool receiving hole 280, which makes it more difficult to align the tool receiving hole 380 with the tool receiving hole 280. This more difficult alignment can improve safety by increasing the difficulty of operating the tool.

[0061] Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawings, it will be understood that the invention is not limited to those precise embodiments, and that various other changes and modifications may be made therein by those skilled in the art without departing from the scope or spirit of the invention.

[0062] Various modifications to the foregoing described and illustrated structures will now be apparent to those skilled in the art. Accordingly, the detailed inventive scope of the present invention is set forth in the following claims.
