Description

Technical Field

[0001] The utility model belongs to the technical field of electronic accessories, and in particular relates to a single-pull telescopic data cable with multi-directional outlets. Background Art

[0002] One definition of a data cable is a channel tool that connects mobile devices and computers. It is mainly used for communication, data transmission or both between devices. As the name suggests: a data cable is a channel tool that connects computers and mobile devices to transmit audio, video, pictures, text and other data. It can also power mobile devices and connect chargers to charge mobile devices. With the development of electronic technology, technicians in the electronic field refer to the extension method of tape measures to design data cables that can be retracted in sections, making them easy for users to carry and requiring little storage space, allowing traditional data cables to automatically retract freely.

[0003] Existing retractable data cables are mainly divided into double-pull and single-pull retractable data cables. For a double-pull data cable, the middle part of a complete data cable is fixed on the central column of a take-up reel, and the data cables at both ends are respectively wound in the take-up reel. This retractable data cable is prone to overlapping and interlacing the windings at both ends, which may cause the take-up reel to be entangled. For a single-pull data cable, one end of a complete data cable close to the input interface is fixed on the central column of the take-up reel, and the other end is wound in the take-up reel. This retractable data cable is prone to single-end pulling out, causing damage to the take-up box. Based on the above reasons, Chinese utility model patent CN207518002U discloses a single-pull retractable charging data cable, including a bottom shell, a front shell, a wire collection mechanism, a positioning track plate, a positioning steel ball, a fixing screw and a decorative cover installed on the upper surface of the front shell, the bottom shell includes a bottom shell body, a center column arranged at the center of the bottom shell body, four ring circuits arranged on the periphery of the center column, a USB PR arranged at the upper left end of the bottom shell body, and a wire connecting line connected between the four ring circuits and the USB PR, which overcomes the technical defects of the existing charging data cable that is easy to overlap the chuck and pull out with a single head. However, this technical solution still has many defects. One is that it needs to be operated with both hands, and it takes at least two stretches to pull the two ends of the data cable apart. The retractable data cable is usually long, and it is easy to make mistakes in operation, which affects the normal extension; the second is that there is only a single corresponding outlet on the shell and the portable single-pull retractable data cable is easily damaged by collision with foreign objects, and once damaged, it must be replaced, which seriously affects the service life of the product.

[0004] Therefore, a single-pull retractable data cable with multi-directional output is proposed to solve the above problems. Utility Model Content

The rotating shaft passes through the rotating installation hole of the rotating assembly, and is inserted into the plug and plugged into the plugging groove through the shell fastening hole. The upper shell positioning installation mechanism and the lower shell positioning installation mechanism are connected by the arc-shaped protrusion and the arc-shaped groove, and are fixed by the plug and the jack. The technical solution increases the number of input terminal outlets by setting circuit board mounting grooves in at least three directions on the upper shell; the upper shell positioning installation mechanism and the lower shell installation positioning mechanism are respectively set on the upper shell and the lower shell, and the number of output terminal outlets is increased while the connectivity between the upper shell and the lower shell is strengthened; by setting a fixed installation hole on the lower shell positioning installation mechanism, the retractable data cable can be fixed as a whole on an object close to the socket, realizing the convenience of single-handed single-pull, and when the outlet is hit, different outlets can be manually maintained and switched, effectively extending the service life of the product.

At the same time, when the stop column moves again, the stop switching groove switches the stop column from the outer stop groove to the inner stop groove to continue moving; the function of the stop switching block is to be set between the inner and outer switching grooves and the stop switching groove to form a switching and stopping structure. The winding reel includes a notch limit block and an arc limit block. At least three notches are set in the middle of the notch limit block to form a wire body passage with the arc limit block.

[0025] like Figure 5 - Fig. 9As shown, the rotating assembly 2 includes a rotating disk 20 and a first circuit board 21. The first circuit board 21 is installed on the fixing column 203 of the rotating disk 20 through a fixing hole 211, and is electrically connected to the second circuit board 12 through a contact 210; wherein the first circuit board 21 is used to connect with the output end wire body, and the second circuit board 12 is used to connect with the input and output end wire body. The electrical connection between the first circuit board 21 and the second circuit board 12 is beneficial to the data transmission of the entire data line or the formation of current directional transmission. The rotating disk 20 includes a stopper disk 20A, a winding disk 20B, and a rotating installation hole 207 and a wire body connection hole 208 that penetrate the rotating disk 20. The stopper disk 20A is mainly used to stop the rotating disk 20 during the rotation process, and the winding disk 20B is mainly used for the retraction winding of the output end wire body after stretching. The stop disk 20A is provided with a stop outer circular groove 201 and a stop inner circular groove 202, wherein the stop outer circular groove 201 and the stop inner circular groove 202 are connected through the inner and outer switching grooves 203 and the stop switching groove 205, and a stop switching block 204 is provided between the inner and outer switching grooves 203 and the stop switching groove 205, wherein the stop outer circular groove 201, the stop inner circular groove 202, the inner and outer switching grooves 203 and the stop switching groove 205 are all the movement trajectories of the stop column 110 on the stop member 11. When the stop post 110 moves, the inner and outer switching grooves 203 function to switch the stop post 110 from the inner stop groove 202 to the outer stop groove 201, and the stop switching groove 205 functions to stop the movement of the stop post 110, realizing the function of segmented line stopping. At the same time, when the stop post 110 moves again, the stop switching groove 205 switches the stop post 110 from the outer stop groove 201 to the inner stop groove 202 to continue moving; the stop switching block 204 functions to be arranged between the inner and outer switching grooves 203 and the stop switching groove 205 to form a switching and stopping structure. The winding reel 20B includes a notch limit block 209a and an arc limit block 209b. At least three notches are arranged in the middle of the notch limit block 209a, and a line body passage is formed between the notch limit block 209a and the arc limit block 209b. The line body connection hole 208 is used to electrically connect the output end line body with the first circuit board 21. The upper housing 10 is provided with an operation hole 108 penetrating the circuit board mounting slot 106 at the rear end of the circuit board mounting slot 106, which facilitates the operation of penetrating the wire body when the wire is output. The rear end of the second circuit board 12 passes through the input terminal outlet 102 to electrically connect the input connector, and the rear end of the first circuit board 21 passes through the output terminal outlet 103 to electrically connect the output connector, thereby increasing the diversity of the connection between the input terminal and the output terminal connector.

[0026] In actual use, the single-pull telescopic data cable with multi-directional outlets provided by the utility model is a fixed single-pull telescopic data cable, so it will be installed on a socket or an object next to a computer through the fixed installation hole 301. Then, the output end wire is pulled with one hand. When stretching, the stop post 110 starts to move from the stop inner circular groove 202 of the stop disk 20A, and switches from the inner and outer switching grooves 203 from the stop inner circular groove 202 to the stop outer circular groove 201. When the output end wire is stretched without stopping, the stop post 110 will make a circular motion in the stop outer circular groove 201. When the wire is fully stretched, the stop post 110 will enter the stop switching groove 205 from the stop outer circular groove 201 and get stuck, stopping stretching and stopping movement; when the wire needs to be retracted, lightly pull the wire and release it, the stop post 110 will enter the stop inner circular groove 202 from the stop switching groove 205 and start a circular motion, driving the entire rotating disk 20 to rotate, and the wire is automatically retracted. When it is fully retracted, the stop post 110 enters the stop outer circular groove 201 from the stop inner circular groove 202 and then enters the stop switching groove 205 to stop moving. When the output end of the stretched wire body is paused according to the desired length, the stop post 110 enters the stop inner groove 202 from the stop switching groove 205 and moves one circle, and then enters the stop outer groove 201 from the stop inner groove 202 through the inner and outer switching grooves 203. When the stretching is continued, the stop post 110 is always in the state of moving in the stop outer groove 201. When the stretching stops, the stop post 110 enters the stop switching groove 205 from the stop outer groove 201 and stops moving. When the stretching is repeated again, the above-mentioned initial state is repeated to achieve the effect of segmented stretching of the stretched wire body. When the segmented recovery is performed, as above, just pull the wire body lightly and release it, the stop post 110 will enter the stop inner groove 202 from the stop switching groove 205 and start a circular motion, driving the entire rotating disk 20 to rotate, and the wire body is automatically retracted. When it is fully retracted, the stop post 110 enters the stop outer groove 201 from the stop inner groove 202 and then enters the stop switching groove 205 to stop moving. When charging or transferring data, simply connect the extended wire connector to the device, and then plug the connector on the input end of the wire into a socket or computer to start data transfer or charging.

[0027] In summary, the utility model increases the number of input terminal outlets 102 by arranging circuit board mounting grooves 106 in at least three directions on the upper shell 10; by respectively arranging an upper shell positioning mounting mechanism and a lower shell mounting positioning mechanism on the upper shell 10 and the lower shell 3, the number of output terminal outlets 103 is increased while strengthening the connectivity between the upper shell 10 and the lower shell 3; by arranging a fixed mounting hole 301 on the lower shell positioning mounting mechanism 30, the retractable data cable can be fixed as a whole on an object close to the socket, realizing the convenience of one-handed single-pull, and when the outlet is hit, different outlets can be manually maintained and switched, effectively extending the service life of the product.
