[0006] Furthermore, the limiting component includes a moving part and a guide channel. The guide channel is located on the side of the adapter plate away from the spring and is distributed around the circuit board. One end of the moving part is fixed to the housing, and the other end is inserted into the guide channel. When the adapter plate rotates under the pull of the user's external force, the moving part can move within the guide channel. A limiting component is provided within the guide channel. When the adapter plate rotates in the opposite direction under the pull of the spring, the limiting component is used to limit the reverse movement of the moving part within the guide channel.

[0007] Furthermore, the moving component includes a fixing component and a moving rod. The fixing component is fixed inside the housing and has a strip-shaped limiting groove. One end of the moving rod is inserted into the limiting groove and can move along the limiting groove, while the other end is inserted vertically into the guide channel and can move along the guide channel.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1As shown, a telescopic cable structure includes a housing 100. An adapter plate 200, rotatable within the housing 100, is disposed within the housing 100. A spring 210 and a data cable 220 are disposed on one side of the adapter plate 200. The spring 210 is fixed to one side of a connecting plate 400. One end of the data cable 220 is connected to the spring 210, and the other end extends out of the housing 100. A circuit board 300 and a connecting plate are disposed on the side of the adapter plate 200 away from the spring 210. 400, the circuit board 300 is electrically connected to the data cable 220, the circuit board 300 is fixed on the adapter plate 200 and rotates synchronously with the adapter plate 200, the connecting plate 400 is fixed inside the housing 100 and forms a rotational electrical contact with the circuit board 300, a limiting component is provided between the adapter plate 200 and the housing 100, the limiting component is used to limit the retraction stroke of the data cable 220 when the data cable 220 retracts inside the housing 100.

[0032] In the working state of this embodiment, the data cable 220 is coiled on the adapter plate 200, with one end connected to the spring 210 and the other end extending from the housing 100. Therefore, when the user pulls the data cable 220 outward, it overcomes the tension of the spring 210 and drives the spring 210 to rotate, thereby driving the adapter plate 200 to rotate. Since a circuit board 300 electrically connected to the data cable 220 is provided on its other side, and when the circuit board 300 rotates synchronously, a rotational contact is formed between the circuit board 300 and the connecting plate 400, the electrical contact between the data cable 220 and the connecting plate 400 can still be ensured when the data cable 220 is stretched inside the housing 100. At the same time, when the user releases the hand, and the data cable 220 retracts into the housing 100 under the action of the spring 210, the limiting component can also limit the retraction stroke of the data cable 220, so that it can be stabilized at a certain retraction length.

[0033] Compared to existing technologies, this application, by providing a circuit board 300 and a connecting plate 400 in the adapter and maintaining rotational electrical contact between them, ensures that the data cable 220 can still maintain electrical contact with the connecting plate 400 when it is stretched within the housing 100. In addition, this application, by setting a limiting component, limits the retraction stroke of the data cable 220, so that the data cable 220 can be stably kept at a certain retraction length, thereby facilitating consumer use.

[0034] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2As shown, a receiving cavity 230 is formed on one side of the adapter plate 200. The spring 210 is disposed in the receiving cavity 230 and can rotate synchronously with the adapter plate 200. The data cable 220 is coiled on the outer wall of the receiving cavity 230. A first through groove 110 is provided on the side wall of the housing 100. One end of the data cable 220 extends into the receiving cavity 230 and is connected to the spring 210. The other end extends out of the housing 100 from the first through groove 110. Therefore, when the user pulls the data cable 220 outward, it will overcome the pulling force of the spring 210 and drive the spring 210 to rotate, thereby driving the adapter plate 200 to rotate.

[0035] Furthermore, based on the above embodiments, such as Figure 2 As shown, a second through groove 231 is provided at the bottom of the receiving cavity 230. The data cable 220 is electrically connected to the circuit board 300 through the second through groove 231. Since the circuit board 300 and the connecting plate 400 form a rotational contact, the data cable 220 can still be electrically connected to the connecting plate 400 when it is stretched inside the housing 100.

[0036] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, the limiting component includes a moving part 510 and a guide channel 520. The guide channel 520 is disposed on the side of the adapter plate 200 away from the spring 210 and is distributed around the circuit board 300. One end of the moving part 510 is fixed to the housing 100, and the other end is inserted into the guide channel 520. When the adapter plate 200 rotates under the pull of the user's external force, the moving part 510 can move within the guide channel 520. A limiting part 521 is provided in the guide channel 520. When the adapter plate 200 rotates in the opposite direction under the pull of the spring 210, the limiting part 521 is used to limit the reverse movement of the moving part 510 within the guide channel 520, thereby limiting the retraction stroke of the data cable 220 and stabilizing it at a certain retraction length.

[0037] Furthermore, based on the above embodiments, combined with Figure 3 and Figure 8As shown, the moving component 510 includes a fixing component and a moving rod 512. The fixing component 511 is fixed inside the outer shell, and a strip-shaped limiting groove 511a is provided on the fixing component. One end of the moving rod 512 is inserted into the limiting groove 511a and can move along the limiting groove 511a, and the other end is vertically inserted into the guide channel 520 and can move along the guide channel 520. In this way, when the moving rod 512 moves up and down in the guide channel 520, the limiting groove 511a can limit the movement range of the moving rod 512.

[0038] Furthermore, based on the above embodiments, combined with Figures 4 to 7 As shown, the guide channel 520 includes at least a first ring channel 522 and a second ring channel 523. The first ring channel 522 surrounds the outside of the second ring channel 523. The limiting member 521 is disposed between the first ring channel 522 and the second ring channel 523. The limiting member 521 includes a first guide portion 521a and a second guide portion 521b. A receiving groove 521c is provided between one end of the first guide portion 521a and the second guide portion 521b. The other ends of the first guide portion 521a and the second guide portion 521b meet and connect.

[0039] The following describes in detail, with reference to the above embodiments, how the guide channel 520 and the limiting member 521 limit the moving member 510, such as... Figure 4 As shown, when an external force pulls the data cable 220, the adapter plate 200 rotates counterclockwise, as shown in direction A in the figure. The data cable 220 is continuously lengthened. In this state, one end of the moving rod 512 moves within the first annular channel 522 (it should be noted that the direction of movement of the moving rod 512 is opposite to the direction of the adapter plate 200). Figure 5 As shown, when the external force disappears, the tension of the spring 210 causes the adapter plate 200 to rotate clockwise, as shown in direction B in the figure. The data cable 220 continuously retracts. In this state, one end of the moving rod 512 is embedded in the receiving groove 521c, thereby preventing the adapter plate 200 from rotating, which in turn causes the retraction of the data cable 220 to stop, allowing it to stabilize at a certain retraction length. Based on this state, as... Figure 6 As shown, when the external force continues to pull the data cable 220, the adapter plate 200 rotates counterclockwise, as shown in direction A in the figure. The data cable 220 continues to grow. In this state, one end of the moving rod 512 enters the second ring channel 523 and moves. When one end of the moving rod 512 passes the intersection of the first guide part 521a and the second guide part 521b, it enters the first ring channel 522, thus repeating the above process. Figure 7As shown, when one end of the moving rod 512 does not pass through the intersection of the first guide part 521a and the second guide part 521b, the external pulling force disappears, and the tension of the spring 210 causes the adapter plate 200 to rotate clockwise, as shown in direction B in the figure. One end of the moving rod 512 moves continuously within the second ring 523, and the data cable 220 retracts continuously until it is coiled back onto the outer wall of the receiving cavity 230.

[0040] Furthermore, based on the above embodiments, such as Figure 8 As shown, a third through groove 120 is provided on the bottom surface of the housing 100, and a protrusion 511b is provided on the fixing member 511. The protrusion 511b is embedded in the third through groove 120, thereby ensuring that the fixing member 511 can be fixed in the housing 100 when the adapter plate 200 is rotated.

[0041] Furthermore, based on the above embodiments, such as Figure 9 As shown, the connecting plate 400 has a plurality of conductive springs 410 on the side facing the circuit board 300. The conductive springs 410 are used to maintain electrical contact with the circuit board 300 when it rotates. This is a common technology, and its principle will not be elaborated here. A fourth through groove 130 is provided on the bottom surface of the housing 100. A connecting end 420 is provided on the connecting plate 400. The connecting end 420 extends out from the fourth through groove 130, thereby facilitating electrical connection with other devices (such as battery compartments).

[0042] Furthermore, based on the above embodiments, such as Figure 1 As shown, an end cap 232 is provided on the receiving cavity 230 to prevent the mainspring 210 from coming out of the receiving cavity 230.

[0043] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
