Description

Technical Field

[0001] The utility model relates to the technical field of data cables, in particular to a telescopic data cable and an electronic product. Background Art

[0002] Data cables are used for connection and communication between electronic products. For example, USB data cables are used for connection and communication between computers and external devices. More popularly, they are used for transmitting data and charging. Data cables are widely used in various occasions. The common data cable has a straight strip-shaped wire body, and its length is not adjustable.

[0003] Later, telescopic data cables appeared. For example, CN215579295U discloses a fracture-proof and durable mobile phone data cable, which relates to the technical field of electronic accessories. The data cable body includes a connecting wire, a USB interface part and a Type-c interface part. The USB interface part and the Type-c interface part are respectively arranged at both ends of the connecting wire. The connecting wire, the USB interface part and the Type-c interface part are the conventional configuration structures of mobile phone data cables. The connecting wire is in a telescopic spiral structure, and reinforcing bosses are arranged at the joints of the USB interface part and the Type-c interface part and the connecting wire. Since its connecting wire is in a telescopic spiral structure, the length of the wire body of the data cable is adjustable.

[0004] However, in actual use, as Figure 9 shown, when a longer wire body length is required, the wire body C of the telescopic spiral structure will be stretched. After unplugging the first interface A and the second interface B, the wire body C will reset under the action of spiral elasticity. When the wire body C of this telescopic spiral structure is used for a long time, especially when the pulling force is large, it is easy to cause local plastic deformation, resulting in a longer length of the wire body C when it is in the retracted state, a larger local turn pitch, and the wire body C cannot maintain a regular shape and appears messy; moreover, when the pulling force is too large, it is easy to affect the connection stability between the two ends of the wire body C and the first interface A and the second interface B, and may cause the wire body C to become loose from the first interface A or / and the second interface B, thereby causing the data cable to be scrapped.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0033] A telescopic data cable includes a cable body 10 and connectors 20 (respectively referring to the first connector and the second connector) connected to both ends of the cable body 10.

[0034] The wire body 10 includes an elastic wire 11 and a telescopic spiral wire 12; the telescopic spiral wire 12 is spirally extended around a set axis, so that an inner hole extending along the set axis is formed inside the telescopic spiral wire 12, and the elastic wire passes through the inner hole and extends out of both ends of the inner hole; both ends of the elastic wire 11 are respectively connected to the first connector and the second connector, and both ends of the telescopic spiral wire 12 are respectively electrically connected to the first connector and the second connector. In the natural retraction state, the length of the elastic wire 11 is equal to the length of the telescopic spiral wire 12; in the stretched state, the pitch between adjacent turns of the telescopic spiral wire 12 becomes larger, and the elastic wire 11 elongates and deforms, being in an elastic energy storage state. Preferably, the maximum elongation of the elastic wire 11 is less than the maximum elongation of the telescopic spiral wire 12. The telescopic spiral wire 12 includes a plurality of sub-wires 121, and the plurality of sub-wires 121 are all spirally extended around the set axis and are alternately arranged in sequence along the set axis. In this embodiment, four sub-wires 121 are provided. A first SR is provided at the tail end of the first connector, a second SR is provided at the tail end of the second connector, straight portions extend outwards from both ends of the telescopic spiral wire 12, and at least the straight portions at both ends are entirely buried inside the corresponding first SR and the second SR, and the telescopic spiral wire 12 is located between the tail ends of the first SR and the second SR. For the plurality of sub-wires 121, straight portions extend outwards from both ends of each sub-wire 121, and the plurality of straight portions are arranged at equal circumferential intervals around the elastic wire 11.

[0035] Generally, the elastic wire 11 includes an elastic soft rubber strip, which has elasticity itself, can undergo elastic deformation, generally does not undergo plastic deformation, and can also refer to an elastic band, an elastic rope, etc. A braided layer can be wrapped outside the elastic soft rubber strip, or some thinner high-strength rubber bands can be added during spinning to form an elastic rope. During actual production, a first wire buckle can be provided on the elastic wire 11, and / or the tail claws of the metal shielding cases 22 of the first connector and the second connector are respectively clamped and fixed to both ends of the elastic wire 11; correspondingly, the SRs 23 of the first connector and the second connector are injection-molded and wrapped and fixed to the first wire buckle and / or the tail claws.

[0036] There is no restriction on the type of the connectors 20 at both ends. During actual design and production, different connector types can be freely combined according to the product requirements. For example, among the first connector and the second connector, one can be any one of a TYPE-C connector, a USB-A connector, a MICRO USB connector, a Lighting connector, and an RJ connector, and the other can be any one of a TYPE-C connector, a USB-A connector, a MICRO USB connector, a Lighting connector, and an RJ connector.

[0037] In this embodiment, the connectors at both ends are a USB-A connector and a TYPE-C connector (plug connector) respectively.

[0038] The first connector is a USB-A connector, which includes a core body 21, a metal shielding shell 22, an SR 23, and an insulating outer mold 24. Generally, the metal shielding shell 22 is wrapped outside the core body 21, then one end of the wire body 10 is welded to the corresponding welding feet at the tail end of the core body 21, and then the SR 23 is injection-molded. The SR 23 is used to wrap and position the welding part, the metal shielding shell 23, and one end of the wire body 10, and then the insulating outer mold 24 is obtained by secondary injection molding. The insulating outer mold 24 wraps around the respective partial positions of the SR 23 and the metal shielding shell 22, so that the tail end of the SR 23 and the head end of the metal shielding shell 22 are exposed outside the insulating outer mold 24.

[0039] The second connector is a TYPE-C connector, which includes a core body 21, an insulating inner mold 211, a metal shielding shell 22, an SR 23, and an insulating outer mold 24. First, the other end of the wire body 10 is welded to the welding feet at the tail end of the core body 21 or the pads on the PCB board, and then the insulating inner mold 211 is obtained by one-time injection molding. The insulating inner mold 211 is used to wrap and position the welding part, or the welding part and the other end of the wire body 10. Then, the two halves of the metal shielding shell 22 are spliced and wrapped outside the core body 21 and the insulating inner mold 211 and welded and fixed; then the SR 23 is injection-molded. The SR 23 is used to wrap and position the insulating inner mold 211, the metal shielding shell 23, and the other end of the wire body 10, and then the insulating outer mold 24 is obtained by three-time injection molding. The insulating outer mold 24 wraps around the respective partial positions of the SR 23 and the metal shielding shell 22, so that the tail end of the SR 23 and the head end of the metal shielding shell 22 are exposed outside the insulating outer mold 24.

[0040] If there are no other accessories covering the outside of the telescopic spiral wire 12, the wire body 10 mainly presents the appearance decoration effect of the wire body with the telescopic spiral wire 12. Of course, the elastic wire 11 inside can also penetrate through the gaps between adjacent turns of the telescopic spiral wire 12, playing an appearance decoration effect to a certain extent. In actual design, several sub-wires of the telescopic spiral wire 12 can be of the same color or different colors. The sub-wires of different colors are convenient for identifying welding wiring and also play the role of enriching colors to present different decoration effects.

[0041] As Figure 7 and Figure 8 shown, it shows the specific structure of the second embodiment, which is basically the same as the structure of the first embodiment. The main difference is that:

[0042] The wire body 10 further includes an elastic braided sleeve 13. The elastic braided sleeve 13 is wrapped around the outer periphery of the telescopic spiral wire 12 to hide both the elastic wire 11 and the telescopic spiral wire 12 inside. In this way, the elastic wire 11, the telescopic spiral wire 12, and the elastic braided sleeve 13 are arranged from the inside out; both ends of the elastic braided sleeve 13 are respectively connected to the first connector and the second connector. Through the setting of the elastic braided sleeve 13, on the one hand, it can play a role in protecting and dust-proofing the elastic wire 11 and the telescopic spiral wire 12, and on the other hand, it is also convenient to present a diverse appearance decoration effect of the wire body through the elastic braided sleeve 13. During production, the tail claws of the metal shielding cases 22 of the first connector and the second connector are respectively clamped and fixed at both ends of the elastic braided sleeve 13. Correspondingly, the SR23 of the first connector and the second connector is injection-molded and wrapped and fixed on the tail claws. The first connector and the second connector of the second embodiment have the same structure as those of the first embodiment, that is: the first connector is a USB-A connector, which includes a core body 21, a metal shielding case 22, SR23, and an insulating outer mold 24; the second connector is a TYPE-C connector, which includes a core body 21, an insulating inner mold 211, a metal shielding case 22, SR23, and an insulating outer mold 24.

[0043] Moreover, there is provided an electronic product, which includes an electronic product main body and a data cable connected to the electronic product main body. The data cable is a telescopic data cable, which includes a wire body and a connector connected to one end of the wire body; the wire body includes an elastic wire and a telescopic spiral wire; the telescopic spiral wire spirally extends around a set axis, so that an inner hole extending along the set axis is formed inside the telescopic spiral wire, and the elastic wire passes through the inner hole; one end of the elastic wire is connected to the connector, and one end of the telescopic spiral wire is electrically connected to the connector.

[0044] The retractable data cable may have connectors at both ends, for example, in the forms shown in Embodiment 1 and Embodiment 2. In this way, one end of the retractable data cable forms a pluggable connection with the main body of the electronic product, and the other end of the retractable data cable is used to connect other electronic products; in other design forms, one end of the retractable data cable may also be fixedly connected to the main body of the electronic product, and the other end serves as a freely pluggable connection end.

[0045] The design focus of the present utility model is that it mainly realizes the retractable function of the data cable by designing the wire body to include an elastic wire and a retractable spiral wire, saves the space occupied by the wire body, and avoids the problems of wire body entanglement and mess. The retractable spiral wire will not cause plastic deformation due to excessive pulling, and has good anti-bending ability; the protection of the elastic wire makes the connection between the retractable spiral wire of the wire body and the connector stable and reliable during actual use, and avoids loosening and falling off.

[0046] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
