Detailed Implementation

[0021] In this embodiment, refer to Figures 1-5 The keychain-type data cable device includes a cable 7 and a housing. The cable 7 is connected to a first connector 5 and a second connector 6. The housing includes an inner shell 1 and an outer shell 2, which are movably assembled with the inner shell 1 to form a relatively sliding structure. An elastic component is installed in the inner shell 1. In this embodiment, the elastic component is a spring 4, but other alternatives with a rebound function, such as rubber or soft rubber, can also be used. The spring 4 presses against the outer shell 2 to form a reset drive structure for the outer shell 2. The first connector 5 has a first connector shell 51, and the second connector 6 has a second connector shell 61. A latching groove 8 is provided on the outer side wall of the first connector shell 51 and the second connector shell 61, respectively. A latching hook 12 is provided along the side wall of the inner shell 1. The length of the latching hook 12 is not very large, just enough to latch the latching groove 8, so that the cable 7 can be pulled out with little effort. After the first connector 5 and the second connector 6 are inserted into the inner shell 1, the latching hook 12 latches the latching groove 7 to fix the first connector 5 and the second connector 6, so that the cable 7 is wound into a closed loop, that is, to form a structure similar to a keychain.

[0022] Notches are provided along both sides of the inner shell 1, and vertical positioning strips 11 are provided in the notches. Hooks 12 are provided at the beginning of the positioning strips 11. This allows the hooks 12 to retract outward when subjected to outward pulling force, making it easier and more convenient to pull out the wire 7.

[0023] A limiting sleeve 23 is provided on the inner wall of the outer casing 2, aligned with the positioning strip 11. The limiting sleeve 23 fits around the limiting strip 11 near the hook 12. This ensures that the wire 7 will not push open the hook 12 under slight force, thus guaranteeing the stability of the connector when inserted into the inner casing 1.

[0024] A stop cover 21 is provided inside the outer shell 2. The stop cover 21 is connected to the outer shell 2 as an integral structure through the connecting arm 22. One end of the spring 4 abuts against the inner shell 1, and the other end abuts against the stop cover 21. When the outer shell 2 is released, the spring 4 pushes the outer shell 2 back to its original position, thus realizing the reset of the outer shell 2.

[0025] The connecting arm 22 has a notch, and the positioning strip 11 passes through the notch to form a guide structure for the extension and retraction of the stop cover 21 and the outer shell 2, so that the outer shell 2 and the inner shell 1 will only perform relative extension and retraction movements, and will not perform rotational movements.

[0026] The first connector 5 and the second connector 6 are of different types; each connector can be a TYPE-C connector, a LIGHTNING connector, a MIRCO-USB connector, or a USB-A male connector. For example, the first connector 5 can be a LIGHTNING connector, and the second connector 6 can be a TYPE-C connector. The appropriate connector can be selected based on the specific needs.

[0027] It also includes a cover 3, which is fixed to the opening end of the inner shell and covers the first connector 5 together with the first connector shell 51 and the second connector 6 together with the second connector shell 61 in the inner shell 1.

[0028] Two guide feet 32 ​​are provided on each side of the bottom surface of the cover 3, opposite to the positioning strip 11. Two hooks 31 are also provided on each side of the bottom surface of the cover 3, with the hooks 31 and the guide feet 32 ​​staggered. A latch 13 is provided on the side wall of the inner shell 1, aligned with the hooks 31. When the cover 3 is fixed to the inner shell 1, the guide feet 32 ​​interlock with the positioning strip 11, and the hooks 31 engage with the latch 13, forming a guiding and fixing structure for the cover 3. Covering the cover 3 improves the product's aesthetics and reduces the entry of dust and other debris into the inner shell 1.

[0029] A buckle 14 is provided at the tail end of the inner shell 1, which can be used to hang other items.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
