Description

Technical Field

[0001] The utility model relates to a telescopic wire structure, in particular to a telescopic wire pull-out identification component and an electronic device. Background Art

[0002] In order to facilitate storage, existing data cables are usually designed to have a telescopic structure installed in the housing. When the data cable is in use, the data cable is pulled out of the housing, and when it is not needed, the data cable is retracted into the housing.

[0003] In pursuit of a higher quality of life, people are increasingly seeking more diverse data cables. For example, the housing often includes a display screen and speakers electrically connected to a circuit board, enabling display and voice notifications. This makes the cable more playable and adds to the product's appeal. However, existing retractable data cables lack a trigger function during the extension process. This means there's no way to determine if the cable has been extended, and turning on the display requires pressing an additional button, making operation cumbersome and lacking in intelligence.

[0004] Therefore, there is an urgent need to develop a retractable wire structure with a data line pull-out trigger circuit. Utility Model Content

[0005] The purpose of the utility model is to provide a retractable wire pull-out identification component and an electronic device that are not only easy to operate but also can realize a power-on triggering function.

The several conductive terminals are respectively and circumferentially slidably connected to the conductive slip rings, and the conductive contacts are circumferentially slidably corresponding to the trigger terminal.

[0012] When the data cable is in a contracted state, the conductive contact and the trigger terminal do not contact each other. When the data cable is pulled to drive the first circuit board on the coiling reel to rotate until the conductive contact contacts and is electrically connected to the trigger terminal, the processor on the second circuit board is triggered and enters the initial working state.

[0013] Furthermore, the telescopic cable pulling-out recognition assembly further includes a second cover covering the first cover. The second cover and the first cover enclose a cavity. The coiling reel, the data cable, and the first circuit board are located in the cavity, and one end of the data cable extends out of the cavity.

[0014] Furthermore, the second circuit board is arranged on the outer side of the second cover. The second cover is provided with an avoidance hole corresponding to the first connector, and the first connector passes through the avoidance hole and extends into the cavity.

[0015] Furthermore, one end of the data cable is connected with a first electrical connector. A limiting block is arranged at one end of the data cable close to the first electrical connector. The first electrical connector and the limiting block are located outside the cavity. When the data cable is tightened, the limiting block abuts against the outer surface of the first cover and / or the second cover to prevent the first electrical connector from entering the cavity.

[0016] Furthermore, a rotating shaft is arranged on the first cover. The coiling reel is provided with a shaft hole, and the rotating shaft is arranged in the shaft hole. The coiling reel can rotate around the rotating shaft.

[0018] Furthermore, the conductive slip ring and the conductive contact are in a gold finger structure.

[0019] Further, at least one second connector is electrically connected to the side of the second circuit board facing the first circuit board. The second connector is provided with several conductive terminals at intervals. The conductive terminals are arranged in one-to-one correspondence with the conductive slip rings, and several conductive terminals are slidably connected to several conductive slip rings in a circumferential manner.

[0020] Further, a second electrical connector is also provided on the second circuit board. The second electrical connector is at least one of the types of USB-A, MicroUSB, Type-C, and Lightning.

[0021] An electronic device includes the above-mentioned telescopic cable pulling-out recognition component. The electronic device further includes a housing. The telescopic cable pulling-out recognition component is installed in the housing, and one end of the data cable protrudes out of the housing.

[0022] For the telescopic cable pulling-out recognition component provided by the present invention, when the data cable is pulled to drive the first circuit board on the cable reel to rotate around the rotating shaft until the conductive contact point contacts and is electrically connected to the trigger terminal and the conductive slip ring and the conductive terminal always remain in conductive connection, the processor on the second circuit board is triggered and enters the initial working state. The present invention not only has simple operation, but also can realize the trigger power-on function, making it more intelligent in use. Moreover, functions such as startup animation and voice broadcast can be added by setting a display screen, a speaker, etc., greatly increasing the interest. Description of the Drawings

[0046] Please refer to Figure 8, Circuit diagram of the telescopic wire pulling recognition component of the present utility model. In this embodiment, the component J1 in area A of the circuit diagram is composed of the conductive slip ring and the conductive contact 41.
