Description

Technical Field

[0001] The utility model relates to the field of data cables, in particular to a telescopic data cable module. Background Art

[0002] With the development of retractable data cables, the combination of retractable data cable modules and corresponding adapters has also developed, such as a car charging head and a retractable data cable module, a power strip and a retractable data cable module, or an adapter and a retractable data cable module, which not only meets the charging needs of the data cable, but also facilitates storage and has a smaller overall size.

[0003] In the existing retractable data cable module, such as Chinese patent CN202323142747.4, the bottom wall of the winding drum is provided with a PCB board, and the winding drum is fixed to the PCB board after passing through the winding drum, thereby realizing the electrical connection of the data cable. However, it is found in actual use that the head end of the data cable is easily worn out during the reciprocating pulling process, thereby affecting the stability of the electrical connection (such as data transmission, charging transmission, etc.).

[0004] In particular, in order to reduce the thickness of the existing winding drum, the top wall is generally removed, so the head end of the data cable will be more worn, thus affecting the service life of the product and further affecting the customer experience. Utility Model Content

[0005] The main purpose of the utility model is to provide a telescopic data cable module, aiming to improve the existing telescopic data cable module, which can not only ensure the rotation and winding stability of the data cable, but also reduce the wear of the end of the data cable, thereby effectively improving the stability of the module.

[0006] To achieve the above object, the utility model provides a retractable data line module, comprising:

[0007] A housing, wherein the housing is provided with an inner cavity;

[0008] A wire winding drum, the wire winding drum is pivotally mounted in the inner cavity, the wire winding drum comprises a base and a surrounding portion extending upward from an upper wall surface of the base, the surrounding portion divides the base into an inner area and an outer area;

[0009] The surrounding part is provided with a positioning part covering the head end of the data line, and when the winding drum rotates, the positioning part is in contact with the inner wall of the shell.

[0010] In the actual design, a positioning portion with a smaller thickness is provided to cover the head end of the data cable. Therefore, when the winding drum rotates relatively, the head end of the data cable will not rub against the shell. Even if the data cable is pulled to the position of the head end, even if the data cable swings in the thickness direction, the protection of the head end of the data cable can be effectively guaranteed, reducing the wear of the head end of the data cable and the PCB board or the wire board, and effectively improving the service life of the telescopic data cable module.

[0031] like Figures 1 to 6 As shown, a retractable data line module includes:

[0032] A housing 1, wherein the housing 1 is provided with an inner cavity 10;

[0033] A wire winding drum 2, the wire winding drum 2 is pivotally mounted in the inner cavity 10, the wire winding drum 2 comprises a base and a surrounding portion 20 extending upward from an upper wall surface of the base, the surrounding portion 20 divides the base into an inner area 21 and an outer area 22;

[0034] The surrounding portion 20 is provided with a positioning portion 3 for covering the head end of the data cable. When the cable winding drum 2 rotates, the positioning portion 3 fits against the inner wall of the housing 1 .

[0035] In the actual design, a positioning portion 3 with a smaller thickness is provided to cover the head end of the data cable. Therefore, when the winding drum 2 rotates relatively, the head end of the data cable will not rub against the shell 1. Even if the data cable is pulled to the position of the head end, even if the data cable swings in the thickness direction, the protection of the head end of the data cable can be effectively guaranteed, reducing the wear of the head end of the data cable and the PCB board or the line board, and effectively improving the service life of the telescopic data cable module.

[0036] The inner area 21 is used to install the torsion spring, and the outer area 22 is used to wind the data line. The bottom wall in the middle of the winding drum 2 is provided with a plurality of first electrodes arranged in concentric circles 4, and the bottom wall of the shell 1 is provided with a second electrode matched with the first electrode, so as to realize electrical connection while the data rotates; the matching mode of the first electrode and the second electrode can also refer to the electric coupler of the concentric circle 4.

[0037] Specifically, the surrounding portion 20 is in a non-circular shape, such as an ellipse or a non-standard ellipse.

[0038] In the embodiment of the utility model, the surrounding part 20 is provided with an escape groove 30 at a position of the positioning part 3 away from the head end of the data line, and the escape groove 30 is arranged through the surrounding part 20 and forms a notch 301. The notch 301 can reduce the friction of the side wall of the data line, thereby reducing the force on the head end, and transferring the force fulcrum to the side wall of the surrounding part 20 opposite to the positioning part 3, thereby reducing the force wear on the head end and effectively improving the stability of use.

[0039] Specifically, a through slot 302 penetrating the base wall is provided at the position of the notch 301. Through the provision of the through slot 302, the upper and lower walls of the head and tail ends of the data line are suspended, thereby reducing wear at the head end of the data line.

[0040] At the same time, the cooperation between the notch 301 and the through slot 302 also facilitates the first end of the data line to be clamped in the positioning portion 3 .

[0041] In the embodiment of the utility model, the winding drum 2 is provided with a concentric circle 4 with its axis as the base point, and the end of the surrounding portion 20 opposite to the notch 301 of the positioning portion 3 is provided with an inner recess 41, and the inner recess 41 is inclined inwardly relative to the concentric circle 4. With the concentric circle 4 as the reference line, the inner recess 41 is inclined inwardly, so that the data cable uses the inner recess 41 as the fulcrum, so the contact area of ​​the fulcrum is larger, which can be understood as the plastic opening bending, which can protect the wire from being crushed.

[0042] Specifically, the positioning portion 3 includes a first side wall 31 and a second side wall 32 that are relatively arranged, and a top wall 33 arranged at the top end of the first side wall 31 and the top end of the second side wall 32, and a clamping groove is formed between the first side wall 31 and the second side wall 32, wherein the rear ends of the first side wall 31 and the second side wall 32 can be closed or can be a through structure, and the head end of the data cable can be covered and fixed by the setting of the clamping groove, thereby effectively reducing the wear of the head end of the data cable caused by the winding reel 2 when it rotates.

[0043] In the embodiment of the utility model, the bottom wall of the winding drum 2 is provided with a first limiting portion 51, a second limiting portion 52 and a third limiting portion 53 which are arranged in sequence from the outside to the inside. The first limiting portion 51 and the second limiting portion 52 form a first track 61, and the second limiting portion 52 and the third limiting portion 53 form a second track 62.

[0044] The second track 62 is provided with an open slot 7, and the second track 62 is provided with a first clamping portion 71 and a second clamping portion 72 on both sides of the open slot 7.

[0045] The guide portion is extended from the first track or is a separate individual

[0046] A guide portion 70 extends from the upper portion of the first clamping portion 71 toward the second clamping portion 72, and an end portion of the guide portion 70 extends toward the first limiting portion 51 and is provided with a spacing. The inclined first limiting portion 51 allows the locking block 8 to be more accurately inserted into the second track 62 from the first track 61, thereby achieving the locking of the winding reel 2 at a predetermined angle of the shell 1.

[0047] Specifically, the housing 1 includes an upper shell 11 and a bottom shell 12, the bottom shell 12 is provided with a swinging locking block 8, and the locking block 8 is provided with a positioning column 80 extending into the first track 61 or the second track 62. Through the swinging setting of the locking block 8 and the positioning column 80, the locking block 8 is provided with a spring, thereby realizing its swing in a single direction. When rotating in the opposite direction, the locking block 8 drives the positioning column 80 to disengage from the open slot 7, thereby realizing locking. The principle thereof can refer to the structure of a one-way ratchet.

[0048] In the embodiment of the utility model, the bottom shell 12 is provided with a pivot column 81, the locking block 8 is provided with a pivot hole 82 matched with the pivot column 81, and the locking block 8 is in a triangular shape, so that the swing is smoother, and of course the triangular structure can also increase the diameter of the pivot column 81, thereby ensuring the stability of the rotation.

[0049] Specifically, the upper shell 11 is provided with a positioning shaft 9 passing through the winding drum 2, the bottom shell 12 is provided with at least two limiting protrusions 91, and the positioning shaft 9 is provided with a limiting groove 92 matched with the limiting protrusion 91. Through the cooperation of the limiting protrusion 91 and the limiting groove, the force exerted on the housing 1 by the winding drum 2 during rotation is reduced. The existing housing 1 is generally designed to be non-circular, and although it can also achieve better limiting, there is still a problem of unstable combination of the bottom shell 12 and the upper cover due to wear of the positioning shaft 9 or wear of the screws.

[0050] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
