[0028] Specifically in this embodiment, the outer shell 1 includes a first outer shell 101 and a second outer shell 102 that are engaged with each other. The first outer shell 101 is provided with a first connecting column 103, and the central island block 204 of the cover plate is provided with an avoidance groove 209 corresponding to the first connecting column. The first connecting column 103 passes through the avoidance groove 209 to connect one end of the spiral spring steel coil 11, and the other end of the spiral spring steel coil 11 is provided with a second connecting column 210 in the accommodating groove of the middle shell body corresponding to the spiral spring steel coil 11.

[0029] Specifically, a buckle 211 is provided at the lower end of the middle shell 2 , and a slot 603 is provided on the contact fixing plate 6 corresponding to the buckle 211 . The middle shell 2 is fixedly connected to the contact fixing plate 6 through the engagement of the buckle 211 with the slot 603 .

[0030] In this embodiment, the contact fixing plate 6 includes an upper plate 601 and a lower plate 602 that are snapped together, the metal contact 7 is arranged on the lower plate 602, and a pad block 604 is arranged at the lower end of the upper plate 601 and on the outer side of the lower plate. The upper plate 601 is supported on the circuit board 8 by the pad block 604, and a guide limit block 605 is arranged on the inner side of the pad block 604. The lower plate 602 is snapped together with the upper plate 601 through the guide limit block 605, and a limit column 607 is arranged at the lower end of the upper plate 601, and a limit notch 608 is arranged on the lower plate 602 for the limit column 607 to avoid relative displacement between the upper plate and the lower plate.

[0031] In addition, a limit block 606 is further provided on the lower plate, and a limit groove 212 is provided at the bottom of the middle shell 2 corresponding to the limit block, so that the connection between the middle shell and the contact fixing plate is more reliable and no relative rotation occurs.

[0032] In this embodiment, the network cable 3 is a flat cable, which is more convenient to store.

[0033] The telescopic network cable of the present invention has a middle shell body arranged in the outer shell body which can rotate synchronously with the network cable, and the middle shell body is connected to the spiral spring steel coil. When the network cable is pulled out, the spiral spring steel coil is tightened synchronously with the pulling out of the network cable, and when the network cable is loosened, the spiral spring steel coil is reset, driving the network cable to be recovered into the outer shell body. In addition, in order to ensure that the pulled-out network cable can be used normally and will not be immediately retracted due to the reset of the spring steel coil, the telescopic network cable of the present invention has a guide groove arranged on the cover plate of the middle shell body, and the guide groove is divided into an inner ring of the guide groove and an outer ring of the guide groove, and a non-return slider is also arranged. The non-return slider is limited by the limit groove on the outer shell body, and the non-return slider can slide along the limit groove. When the network cable is pulled out, the guide groove rotates under the drive of the middle shell body, so that the clamping column of the non-return slider can rotate in the inner ring of the guide groove or the outer ring of the guide groove relative to the inner ring of the guide groove or the outer ring of the guide groove. , at this time, the rotation direction is opposite to the opening direction of the limit slot, so that the post will not contact the limit slot during the rotation process, and when the network cable is recovered under the action of the spiral spring steel coil, the guide slot rotates under the drive of the middle shell, and the post of the non-return slider can rotate relative to the inner ring of the guide slot or the outer ring of the guide slot. At this time, the rotation direction is opposite to the opening direction of the limit slot. When the network cable is recovered under the action of the spiral spring steel coil, even if the network cable is only recovered for a short section, in fact, the post of the non-return slider has rotated many times around the inner ring of the guide slot or the outer ring of the guide slot. During this process, there is a certain probability that the post is stuck in the limit slot, thereby limiting the rotation of the middle shell, and then limiting the retraction of the network cable under the action of the spiral spring steel coil, so that the network cable will be stuck and will not be automatically recovered; pulling the network cable outward again will cause the post to fall out of the limit slot;

[0034] When the network cable is released, the network cable will continue to be recovered under the action of the spiral spring steel coil. When the network cable is completely released and free, the relative rotation speed between the guide groove of the middle shell and the clamping column is faster, and the clamping column is not easily stuck in the limit clamping groove, which makes it convenient to retract the network cable. When the network cable is pulled during recovery, which makes the recovery of the network cable relatively slow, the relative rotation speed between the guide groove of the middle shell and the clamping column is slower. When the clamping column moves between the inner circle of the guide groove and the outer circle of the guide groove, the clamping column is easily stuck in the limit clamping groove under the guidance of the gap between the inner circle of the guide groove and the outer circle of the guide groove. In this way, the network cable can be limited after being pulled out, which makes it convenient to use the telescopic network cable of the present invention.

[0035] The telescopic network cable of the present invention is provided with a wound network cable in an outer shell, one end of the network cable extends out from the outer shell and is connected to a crystal head, so that the network cable can be pulled out of the outer shell, so that a longer network cable can be accommodated in a smaller outer shell, which is convenient for storing and arranging the network cable; the core wire at the other end of the network cable is connected to a contact fixing plate, and the metal contact on the contact fixing plate contacts with a gold finger on a circuit board; a network module connected to the gold finger is also provided on the circuit board, so that the other end of the telescopic network cable can be connected to the network module, thereby realizing the integration of the network module into the telescopic network cable, which can be stretched when in use and retracted when not in use, has a reasonable structure, is convenient for stretching and recycling the network cable, is no longer loose and tangled, and can be easily arranged.

[0036] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
