Moreover, while the subject disclosure will now be described in detail with reference to the Figures, it is done so in connection with the illustrative embodiments. It is intended that changes and modifications can be made to the described embodiments without departing from the true scope and spirit of the subject disclosure as defined by the appended paragraphs.

DETAILED DESCRIPTION OF THE DISCLOSURE

[0028] The present disclosure details a cable jacket, and a manufacturing method thereof, wherein the cable jacket is capable of repeated assembly and disassembly, which allows for manipulation of the inner cables, while allowing the jacket to sufficiently protect the inner cables by preventing any exposure of the inner surface of the jacket to the environment.

[0029] As provided earlier, the current art in the field has several shortcomings associated with cable jackets. Namely, reassembled jackets are prone to separation when the jacket is manipulated and bent, thus exposing the delicate inner cables the jacket was designed to protect. As seen in FIG. 1, the prior art depicts a common jacket having two channels for accommodating two inner cables. The jacket is prone to separation, especially when the cable jacket is bent with the opening element configured on or near the outer periphery of the bend.

[0030] The above mentioned problems can be resolved by using the cable jacket disclosed in the present innovation. As provided in FIGS. 3a-c and 4a-c, the subject cable jacket 10 features two internal channels 12a and 12b and a resealable closure 14 configured for repeated sealing. In one embodiment, the closure may be made by extruding a flexible elastomeric material such as polyurethane, silicone, or a similar material. The internal channels 12a and 12b may be configured to accept desired sub-cables, as well as other lines/wires which may benefit from a protective jacket. The resealable closure 14 comprises of two non-connected flaps, inner flap 16 and outer flap 18, which overlap to seal the internal channels 12a and 12b. In the present embodiment, the inner flap 16 and outer flap 18 are tapered, but may incorporate other shapes as specified. The overlapping inner flap 16 and outer flap 18 are configured to remain in contact even if the cable jacket 10 is manipulated. In one embodiment, manipulation of the cable jacket 10 may lead to the inner flap 16 sliding along the outer flap 18 to retain the sealed jacket 10.

[0031] The inner flap 16 may be molded or otherwise configured to be resiliently urged towards the center 20 of the cable jacket 10, while the outer flap 18 may be molded or otherwise configured to be resiliently urged away from the center 20 of the cable jacket 10. Accordingly, and as seen in FIG. 3b, in the assembly configuration, the inner flap 16 is inside the outer flap 18 and urged towards the center 20 the jacket 10, while the outer flap 18 is outside the inner flap 16 and urged away from the center 20 of the jacket 10. This assembly configuration may create a gap 22 between the inner flap 16 and outer flap 18, thus allowing for easier access into the jacket 10 for addition and/or removal of a cable.

[0032] In the sealed configuration, and as seen in FIG. 3c, the inner flap 16 is outside the outer flap 18 and urged towards the center 20 the jacket 10, while the outer flap 18 is inside the inner flap 16 and urged away from the center 20 of the jacket 10. This sealed configuration urges the inner flap 16 and outer flap 18 together, thus urging the inner flap 16 and outer flap together to create a seal.

[0033] In the assembly configuration of FIG. 3c, the sub-cables 24a and 24b are inserted into corresponding channels 12a and 12b, and then the inner flap 16 and outer flap 18 are reversed so the corresponding contact surfaces 26 and 28, respectively, are facing and contacting each other. The resiliently deformed inner and outer flaps 16 and 18 will exert return forces on each other leading to positive closure of the cable jacket 10 through friction between contact surfaces 26 and 28.

[0034] Alternatively, only one of the two flaps, 16 and 18, may be resiliently deformed to create the return force necessary to urge the flaps together in the sealed configuration, as well as to create the gap 22 between the inner flap 16 and outer flap 18 in the assembly configuration.

[0035] As provided in FIGS. 4a-4c, and depending on the design, intent, and cable bending requirements, the contact surfaces 26 and 28 may be supplanted with additional features to further enhance closure opening and/or ease of manipulation of sub-cables 24a and 24b. In addition, the additional features may contribute to jacket 10 resilience during cable bending. For example, the contact surfaces 26 and 28 may be configured with ribbing or teeth 30, both symmetric (FIGS. 4b and 4c) and asymmetric self-locking, adhesive, either temporary or permanent, applied to one or both surfaces, zip-lock type closure, or other frictional means to further secure the contact surfaces 26 and 28 to secure the jacket 10.

[0036] Additional embodiments on the subject jacket are detailed in FIG. 5a, 5b, 6a and 6b, wherein side and cut-away views, of the cable jacket are provided in the open (5a, 5b) and closed (6a, 6b) configuration. In these examples of the jacket 10, the two flaps, 16 and 18, may be resiliently deformed to create the return force necessary to urge the flaps together in the sealed configuration. In this embodiment, the two flaps, 16 and 18, have additional curves to increase the contact surface area between the two flaps, thus further ensuring the jacket 10 remains sealed when the jacket 10 is manipulated. As before, the flaps 16 and 18 are configured to create the gap 22 between the inner flap 16 and outer flap 18 in the disassembly configuration, in order to facilitate easier insertion and/or removal of the cables (not shown— 24a and 25b). The urging of the flaps, 16 and 18, further ensures the jacket 10 remains sealed in the closed configuration, thus protecting the cables from the outer elements.

[0037] Although a hook and loop type orientation has been detailed in FIGS. 5a, 5b, 6a and 6b, this disclosure is intended to include various different shapes and patterns which may be configured for various advantages, as the situation may deem necessary. By way of example only, a tongue and groove orientation may be utilized, or a “S” pattern may be utilized, as well as bevy of other known closure techniques.
