DETAILED DESCRIPTION

The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

Please refer toFIG.1, which depicts an application schematic view of the cable strain relief structure in this disclosure. A cable strain relief structure1in this disclosure is used to connect an electronic device2or a connector, etc. In this embodiment, the electronic device2is a power supply, but it is not limited thereto. The cable strain relief structure1includes a conducting seat a cable20, a supporting element30and an insulating sleeve40. The cable20is electrically connected to the conducting seat10. The supporting element30covers the cable20. The insulating sleeve40is connected with the conducting seat10and covers the supporting element30to configure the cable strain relief structure1.

Please further refer toFIG.2andFIG.3, which depict a perspective view of the cable strain relief structure without being covered by the insulating sleeve and a side view of the cable strain relief structure in this disclosure. The conducting seat10includes an insulating body11and a conducting element12disposed in the insulating body11. Furthermore, the conducting element12includes a plug, a connector, or a plurality of conducting wires. In this embodiment, the conducting element12includes a plurality of conducting wires.

The cable20passes through the insulating body11and is electrically connected to the conducting element12. In some embodiments, the cable20includes a plurality of twisted pairs or a copper coaxial cable, etc.

Moreover, the supporting element30includes a plurality of ridges31arranged spacedly and annularly on the outer periphery of the cable20. The ridges31are extended in the direction along the cable20and away from the insulating body11. In one embodiment of this disclosure, each ridge31is an elongated rib and has a claw311disposed on the end thereof. Additionally, the ridges31are disposed parallelly and annularly on the surface of the cable20.

In this embodiment, the supporting element30further includes an inner annular plate32. The inner annular plate32is disposed between the insulating body11and the ridges31. One side of the inner annular plate32is connected to the insulating body11, and another side of the inner annular plate32is connected to the ends of the ridges31. In some embodiments, the ridges31and the inner annular plate32are formed as one piece (or integrally formed).

Furthermore, the insulating sleeve40covers the supporting element30and is extended along the cable20. In some embodiments of this disclosure, the insulating sleeve40includes a conical opening41defined relatively to one side of the conducting seat10.

Please further refer toFIG.4andFIG.5, which depict a perspective schematic view and a side view of another embodiment of the cable strain relief structure in this disclosure. This embodiment is similar to the previous embodiment. The cable strain relief structure1aincludes a conducting seat10a, a cable20a, a supporting element30aand an insulating sleeve40a. The structures of the conducting seat10a, the cable20aand the insulating sleeve40aare the same as the previous embodiment. The difference between this embodiment and the previous embodiment is the structure of the supporting element30a.

The supporting element30aincludes a plurality of ridges31aand an inner annular plate32a, and the ridges31aare disposed spacedly and annularly. In this embodiment, the width of each ridge31ais gradually decreased from one side of the inner annular plate32atoward the direction away from the conducting seat10a.

Please refer toFIG.6andFIG.7, which depict a perspective schematic view and a side view of still another embodiment of the cable strain relief structure in this disclosure. This embodiment is similar to the previous embodiment. The cable strain relief structure1bincludes a conducting seat10b, a cable20b, a supporting element30band an insulating sleeve40b. The structures of the conducting seat10b, the cable20band the insulating sleeve40bare the same as the previous embodiment. The difference between this embodiment and the previous embodiment is the structure of the supporting element30b.

The supporting element30bincludes a plurality of ridges and an inner annular plate32b, and the ridges31bare disposed spacedly and annularly. In this embodiment, each ridge31bincludes a supporting section311b, a necked section312band an extension section313bin different widths. The supporting section311bis connected to the inner annular plate32b. The necked section312bis disposed between the supporting section311band the extension section313b. Specifically, a supporting distance314bis defined between the supporting sections311bof any two ridges31badjacent to each other. Moreover, an extension distance315bis defined between the extension sections313bof any two ridges31badjacent to each other. In this embodiment, the supporting distance314bis smaller than the extension distance315b.

Please further refer toFIG.8andFIG.9, which depict a perspective schematic view and a side view of another embodiment of the cable strain relief structure in this disclosure. This embodiment is similar to the previous embodiment. The cable strain relief structure1cincludes a conducting seat10c, a cable20c, a supporting element30cand an insulating sleeve40c. The structures of the conducting seat10b, the cable20band the insulating sleeve40bare the same as the previous embodiment. The difference between this embodiment and the previous embodiment is the structure of the supporting element30c.

The supporting element30cincludes a plurality of ridges31cand an inner annular plate32c, and the ridges31care disposed spacedly and annularly. In this embodiment, the width of each ridge31cis gradually decreased toward the direction away from the conducting seat10c. It is worth noticing that the ridges31cand the inner annular plate32cmay be made of different materials (heterogeneous materials) to increase the gradient of stress transition. When the injection molding is performed for the inner annular plate32c, the ridges31care put into the mold for injection molding together with the inner annular plate32c.

Please further refer toFIG.10andFIG.11, which depict a perspective schematic view and a side view of another embodiment of the cable strain relief structure in this disclosure. This embodiment is similar to the previous embodiment. The cable strain relief structure1dincludes a conducting seat10d, a cable20d, a supporting element30dand an insulating sleeve40d. The conducting seat10dincludes an insulating body11dand a conducting element12ddisposed in the insulating body11d.

In this embodiment, the conducting element12dincludes a plug element. The supporting element30dincludes a plurality of ridges31dand an inner annular plate32d, and the ridges31dare disposed spacedly and annularly. The plurality of ridges31dare disposed in a jagged shape. It should be noted that the insulating sleeve40dcovers the insulating body11d, part of the conducting element12dand the supporting element30d. The insulating sleeve40dis extended in the direction along the cable20d. Specifically, the insulating sleeve40dis disposed in an L-shape.

While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
