Description

Technical Field

[0001] This utility model relates to a retractable data cable with an integrated terminal block, and belongs to the technical field of retractable data cable devices. Background Technology

[0002] Data cables are essential charging devices for modern electronic devices. Conventional data cables have a fixed length, which is inconvenient to store and carry. Therefore, some retractable data cables can meet people's needs for carrying and charging.

[0003] Existing retractable data cables typically consist of two data cable segments connected to a turntable, with length positioning via a locking mechanism. The turntable houses a PCB board, conductive connectors, and terminals. Spring contacts on the terminals engage with conductive discs on the PCB board for conductivity, facilitating use. However, existing retractable data cables often have separate conductive connectors and terminals. Assembly requires first installing the terminals onto the conductive connector, then the connector onto the conductive PCB board, and finally soldering the data cable to the conductive PCB board and connecting it to the conductive terminals. The PCB power supply board is connected to the conductive disc via wires and then soldered to the other data cable segment. This complex structure involves numerous components, requiring an additional PCB board for circuit input control before connecting to the PCB power supply board, making assembly cumbersome and costly. Furthermore, existing terminals are often small-area structures, resulting in high overall voltage drop after multiple connections, impacting performance. Therefore, this paper proposes a retractable data cable with integrated terminals to address these issues. Utility Model Content

Detailed Implementation

[0027] See Figures 1-9As shown, the technical solution adopted in this specific embodiment is as follows: It includes a data cable storage housing 1 and a take-up rotating disk 2. The take-up rotating disk 2 is movably disposed inside the storage housing 1. The take-up rotating disk 2 winds up a data cable 5 connected to the user device. A rotating PCB board 3 is provided at the bottom of the rotating disk 2. The rotating PCB board 3 is soldered to the data cable 5. A terminal block 4 is provided below the rotating PCB board 3. The terminal block is a fixed structure. The connection between the take-up rotating disk and the rotating PCB board is also a rotating structure. The terminal block 4 includes an integrated connector 41 and a connector 42. The end of the connector 42 is soldered to a wire 9, and the front end of the connector 42 is electrically connected to the bottom of the rotating PCB board 3. This embodiment provides a semi-finished structure for a retractable data cable. A charging connector matching the power supply end needs to be connected to the wire according to production and demand requirements. For electrical ports, the connectors used in traditional rotating structures for conductive parts are mostly separate structures, including a terminal mounting mold and a power input PCB board. The wires need to be soldered to the PCB board first, and then the PCB board is connected to the conductive terminals on the connector through connecting wires. After that, the connector contacts the conductive pad to achieve electrical connection. This not only involves a lot of structure, but also requires the power supply wires to pass through the PCB board before connecting to the connector, resulting in greater losses. Therefore, in this embodiment, an integrated connector and connecting terminal are set up. The two constitute a terminal block, and the connecting terminal directly completes the electrical connection with the rotating PCB board. After the wires are soldered to the terminal block, the electrical connection with the rotating PCB board can be achieved without the need for a transitional connection through a PCB board. This not only reduces the overall structural components, but also reduces the current path by ≥40% and the voltage drop by 15%~20%.

[0028] More specifically, the bottom of the rotating PCB board 3 is concentrically provided with five gold-plated conductive rings 31. The edge of the rotating PCB board 3 opposite to the gold-plated conductive rings 31 is provided with an output conductive connecting piece 32, and the output conductive connecting piece 32 extends toward the gold-plated conductive rings 31 and is electrically connected to them. In this embodiment, the gold-plated conductive rings are directly embedded into the bottom of the rotating PCB board, which can reduce the overall thickness. The rotating PCB board completes the electrical connection with the terminal block through the gold-plated conductive rings.

[0029] More specifically, the connector 41 has symmetrical conductive grooves 411 in the middle, and a terminal fixing groove 412 is provided between the two conductive grooves 411. The lower end of the connector 41 has several solder pads 413, which are mainly used for soldering wires on them. A fixing buckle 414 is provided on the side of the top center of the connector 41 away from the rotating PCB board 3. In the traditional structure, the connector is usually fixed to the housing by dispensing glue, which has low installation efficiency. However, in this embodiment, a fixing buckle structure is used. By fixing the connector to the data cable housing, the installation efficiency can be effectively improved and the production cost can be reduced.

[0030] More specifically, the connecting terminal 42 is an integral conductive copper sheet, including a contact spring end 421 and a connecting piece end 422. The top of the contact spring end 421 is bent into an arc shape and extends out of the conductive groove. The top of the arc-shaped surface contacts the gold-plated conductive ring. There are ten contact spring ends 421 in total, arranged symmetrically from the center to both sides in pairs, for a total of five groups. Each group of contact spring ends 421 is connected through the connecting piece end 422. In this embodiment, in order to flatten the terminal block and improve transmission efficiency, the connecting terminal is set as an integral conductive copper sheet structure, while the traditional structure usually has the contact spring end at the end of the wire. The direct soldering of the terminal block structure to the PCB board on which it is mounted results in a smaller conductive area and a higher voltage drop due to multiple connections. In this embodiment, ten contact springs are arranged in five groups, enabling each signal channel to be dual-channel, which can effectively improve output efficiency. At the same time, the contact springs directly contact the gold-plated conductive ring for electrical connection, and the connecting plate is soldered to the wire, thereby realizing the electrical connection of wire → connecting terminal → gold-plated conductive ring. The power supply connection components are fewer than those in the traditional structure, thus effectively reducing the voltage drop. Combined with the dual-channel structure, it ensures stable and efficient transmission of signals and power, which is more conducive to the implementation of fast charging solutions.

[0031] More specifically, the innermost set of bottom contacts of the contact spring end 421 is connected by a transverse connecting piece end 422, and the transverse connecting piece end 422 extends upward near the innermost contact spring end 421, and then connects again at the top to extend laterally to the outermost side and finally bends downward. The innermost contact spring end and its matching connecting piece end form a separate signal path, and the connection wires of the data power supply end are connected according to the specific functional requirements, which is conducive to distinguishing it from other path functions.

[0032] A hollow connecting post 425 is provided between the innermost group of contact spring ends 421 and is connected to the upward extension of the contact spring end 421 and is sleeved with the fixing groove 412. In order to ensure the tightness of the connection terminal and the connection seat and to facilitate the rotation of other components during integrated production, the hollow connecting post and the fixing groove are provided to cooperate.

[0033] More specifically, the other four groups of contact spring ends 421 are connected to inclined connecting plate ends 422 at their bottoms, forming a Y-shape. The bottom of the Y-shape is the welding end 423, which is connected to the solder pad 413 and welded to the wire 9. In this embodiment, in order to arrange the connecting terminals in a compact space, the connecting plate ends are arranged in a Y-shape, and the contact spring ends of the same group cooperate to form a Y-shape. The bottoms of the non-adjacent connecting plate ends of the same group are horizontally connected to form a welding end for welding to the wire. Since the spacing between the different groups of connecting plate ends is different, it has a high degree of identification and can better weld the corresponding wires as needed.

[0034] More specifically, the contact spring end 421 and the connecting piece end 422 are spaced apart. A support plate 424 is provided at the transition position between the contact spring end 421 and the connecting piece end 422. A support plate 424 is also provided between adjacent connecting piece ends 422. The support plate is an insulating structure to prevent different sets of contact spring ends from contacting the connecting piece ends and avoid short circuits.

[0035] More specifically, the take-up rotary disk 2 has a take-up cavity 23 on the side away from the rotating PCB board 3. A wire groove 24 is provided on the side wall of the take-up cavity 23, communicating with the interior. A rotating spring 6 is provided inside the take-up cavity 23 for taking up the data cable and providing take-up restoring force. The rotating spring 6 is wound within the take-up cavity 23, and one central end of the rotating spring 6 is bent to form a fixed end 61. This fixed end is connected to the data cable storage housing and is a non-rotating part. The outer end of the rotating spring 6 is the take-up end 62, which is engaged in a locking groove 25 provided inside the take-up cavity 23. The grooves work together to allow the take-up rotating disc to be pulled, causing the rotating spring to unfold and the fixed end to be fixed. This allows the rotating spring to rewind around the fixed end. A data cable 5 is arranged around the outside of the take-up cavity 23. One end of the data cable 5 is provided with a connection end for connecting to the device charging port, and the other end is an electrical connection end. The electrical connection end passes through the wire groove 24 and is fixed therein. The conductive wire of the electrical connection end passes downward through the take-up rotating disc 2 and is welded to the output conductive connection piece 32. The data cable is fixed in the wire groove and can pull the take-up rotating disc to rotate. The wire part is welded to the output conductive connection piece.

[0036] More specifically, the data cable storage housing 1 includes an upper housing 11 and a lower housing 12, which are snapped together. A rotating column 111 is centrally located on the upper housing 11, passing through a rotating spring 6, a take-up rotating disk 2, a rotating PCB board 3, and a terminal block 4, and finally inserts into a mating groove centrally located on the lower housing 12. The rotating column serves as a rotation limiter for the take-up rotating disk and the rotating PCB board, and also as a positioning element for the rotating spring and the terminal block. A spring fixing groove 112 for mounting a fixed end 61 is axially formed at the bottom center of the rotating column 111. The fixed end snaps into the fixing groove, allowing the rotating spring to unfold and rewind due to rotation within the take-up cavity. A friction plate 8 is fitted onto the top of the rotating column 111, contacting the rotating spring 6. In existing structures, this structure is generally not present, resulting in significant noise during rotation and wear on the housing contact parts due to friction. In this embodiment, with the friction plate, the rotating spring does not directly contact the upper housing; the bottom surface of the friction plate is smooth, and it interacts with the rotating spring. When friction occurs during contact, noise can be reduced, and the upper housing is also protected. The lower housing 12 is provided with a snap-fit ​​fixing groove 122 that cooperates with the fixing snap 414. In traditional structures, connectors are usually fixed with glue, which is cumbersome and takes a long time. However, the method of using the snap-fit ​​and the snap-fit ​​fixing groove can quickly install and fix the connecting terminal without glue, which not only improves the assembly speed but also saves production costs. The lower housing 12 is provided with a terminal mating groove 123 corresponding to the wire 9. After the connecting terminal is engaged with the lower housing, the lower part enters the terminal mating groove for circumferential limitation. The limiting effect of the rotating column can effectively prevent the connecting terminal from moving. A fixing post 121 is provided on one side of the inner edge of the lower housing 12. A locking block 7 is movably provided on the fixing post 121. A guide protrusion 71 is provided on the side of the locking block 7 facing the take-up rotating disk 2. The locking block is the main locking structure for the extension and retraction of the data line in this embodiment. It achieves the extension and positioning of the data line by cooperating with the take-up rotating disk.

[0037] More specifically, the bottom of the take-up rotary disk 2 is provided with two adjacent layers of guide grooves 21, making the guide grooves a multi-layered structure. This allows the guide protrusion to move within the guide grooves of different layers. A conical guide block 22 is provided at the opening of the guide groove 21, and it is a conical structure inclined towards the center. The wide end of the guide block faces the opening of the guide groove. This opening is the meeting point of two different layers of guide grooves, and there are two such openings. One opening facing the wide part of the guide block is a narrow opening, and the other opening is located at the narrow opening of the guide block, i.e., its conical tip, which is a wide opening. The first opening on the outer side of the guide groove widens at the wide part of the guide block, while the second opening narrows along the direction of the conical tip of the guide block. Block 22 has a slot 221 at the opening of the guide groove 21 that cooperates with the guide protrusion 71. When the data cable is stretched, the guide protrusion moves circumferentially from the narrow part of the guide block to the wide part, and moves within the inner guide groove. When it contacts the narrow part of the guide block, it is pushed outward by the inclined wide part and moves to the outer guide groove. After the data cable is released, it moves in the opposite direction under the action of the rotating spring. Because it is blocked by the slot during the reverse movement, it is stuck in the slot. The slot has a partition structure that divides the guide groove into layers. Its end is provided with an inclined surface towards the inner guide groove. Therefore, when the data cable is stretched again, the guide protrusion will be guided to the inner layer of the guide groove. This method realizes the positioning of the data cable after stretching. The overall structure is simple and the positioning effect is good.

[0038] The working principle of this utility model is as follows: This retractable data cable is a semi-finished product. Depending on actual production needs, a power supply port for connection to the power supply equipment needs to be welded to the end of the wire. During normal use, stretching the data cable 5 causes the winding spring 6 to unfold, thereby obtaining a winding recovery force. During this process, the guide protrusion 71 on the locking block 7 moves within the guide groove 21. When the data cable 5 is released, the winding spring rewinds, causing the data cable 5 to rewind as well. At this time, the guide protrusion 71 returns along its original path. When passing through the opening of the guide groove 21, because the guide block 22 corresponds to the opening position, the guide protrusion 71 engages in the slot 221, achieving locking. During the entire rotation... During the process, the contact spring end 421 always maintains close contact with the gold-plated conductive ring 31 at the bottom of the rotating PCB board 3 to achieve electrical connection. Since the connection terminal 42 adopts a wide-plate dual-channel structure, the overall conductive transmission area is large. After the wire 9 is directly connected to the connection terminal 42 and soldered, it is electrically connected to the gold-plated conductive ring 31 and the rotating PCB board 3, which reduces the need for a transition PCB board structure in the traditional structure. This can effectively reduce voltage drop and thus obtain better power supply and data transmission effects. In addition, the wide-plate integrated structure makes the overall structure thinner, which is conducive to the flattening design of the winding mechanism and improves the user experience.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
