[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0036] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0037] In addition, the terms "installed", "set", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be directly connected, or indirectly connected through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0039] In mobile terminals such as mobile phones and tablets, Cable usually refers to cables used for charging or data transmission. For charging, Cable is a power cable used to transfer electrical energy from a power source to mobile devices such as mobile phones to provide power to the devices. This type of cable usually has a high current transmission capacity to ensure that it can provide sufficient power to the device. For data transmission, Cable is a data cable used to connect mobile devices such as mobile phones and computers or other devices. It can transfer data from one device to another, such as when synchronizing mobile phone data or backing up photos and videos. This type of cable usually has a faster transmission speed and can efficiently transfer large amounts of data.

[0040] In the related art, the cable (hereinafter referred to as the cable) is usually arranged in a wire groove of the mobile terminal housing, and a protrusion is arranged on a side wall of the wire groove to clamp the cable. However, in this way, the cable is easy to be warped or partially protrude from the wire groove, resulting in limited cable clamping, affecting the assembly between the mobile terminal housings, resulting in poor assembly between the mobile terminal housings, and further affecting the quality of the final mobile terminal.

[0041] Based on this, the present application discloses a cable fixing structure and a mobile terminal having the cable fixing structure. The cable fixing structure is provided with a first protrusion on the first side wall of the wire groove, and the first protrusion extends to the bottom surface of the wire groove and is connected to the bottom surface, and a second protrusion protruding toward the first protrusion is provided on the second side wall, so that a space for clamping the cable can be formed between the second protrusion and the first protrusion. In this way, since there is a gap between the side of the second protrusion facing the bottom surface and the bottom surface, the first protrusion can clamp the cable in the first direction Y of the wire groove, and the second protrusion can clamp the cable in the second direction of the wire groove, thereby clamping the cable from different directions, so that the cable can be firmly clamped in the wire groove, avoiding the situation that the cable falls out of the wire groove or is pushed out during the assembly process, effectively improving the installation reliability of the cable, and thus facilitating the improvement of the assembly yield of the shell of the mobile terminal.

[0042] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0043] See also Figure 1 The embodiment of the present application discloses a cable fixing structure 100, which can be used for a mobile terminal 200. Specifically, the mobile terminal 200 may include a housing 201, and the housing 201 is connected to the cable fixing structure 100. It can be understood that the mobile terminal 200 may include but is not limited to a mobile phone, a tablet computer, etc. Taking the mobile terminal 200 as a mobile phone as an example, the housing 201 may include a front housing, a rear housing, and a middle frame, etc. When the housing 201 includes a middle frame, the cable fixing structure 100 may be connected to the middle frame.

[0044] The specific structure of the cable fixing structure 100 of the present application will be described in detail below with reference to the accompanying drawings.

[0045] Please also read Figures 2 to 4 The cable fixing structure 100 comprises: a fixing body 1, a first protrusion 2 and a second protrusion 3. The fixing body 1 is provided with a wire groove 11 extending along the length direction of the fixing body 1, and the wire groove 11 comprises a first side wall 12, a second side wall 13 and a bottom surface 14, the first side wall 12 is arranged opposite to the second side wall 13, and the bottom surface 14 is connected to the first side wall 12 and the second side wall 13. The first protrusion 2 is arranged on the first side wall 12, and extends to the bottom surface 14 and is connected to the bottom surface 14. The second protrusion 3 is arranged on the second side wall 13, and protrudes in the direction toward the first protrusion 2 to form a space 18 for accommodating the cable between the first protrusion 2, and a side of the second protrusion 3 facing the bottom surface 14 is spaced from the bottom surface 14, the first protrusion 2 is used to clamp the cable in the first direction Y, and the second protrusion 3 is used to clamp the cable in the second direction X.

[0046] The first direction Y is the protruding direction of the first protruding portion 2, and the second direction X is the direction of the second protruding portion 3 toward the bottom surface 14 (eg Figure 3 shown).

[0047] The first protrusion 2 and the second protrusion 3 provide four constraints for the cable in the space 18. Specifically, the first protrusion 2 limits the translation of the cable along the first direction Y and the rotation around the second direction X, and the second protrusion 3 limits the translation of the cable along the second direction X and the rotation around the first direction Y, wherein the "rotation around the second direction X" is manifested in the flexible cable as a certain section of the cable protruding from the opening of the cable groove 11. In addition, the first protrusion 2 also has a clamping effect on the cable, making it difficult for the cable to move or rotate in the direction in which it extends, so that the cable can be more firmly fixed in the cable groove 11, reducing the possibility of the cable protruding, warping or falling out of the cable groove 11 during the assembly process of the mobile device, thereby effectively improving the installation reliability of the cable, and further facilitating the improvement of the assembly yield of the shell 201 of the mobile terminal 200.

[0048] Optionally, the first protrusion 2 can be a long strip-shaped block, the number of the first protrusions 2 can be set to multiple, and the multiple first protrusions 2 are arranged at intervals along the extension direction of the wire groove 11. Correspondingly, the second protrusion 3 can also be a long strip-shaped block, the number of the second protrusions 3 can also be set to multiple, and the multiple second protrusions 3 are arranged at intervals along the extension direction of the wire groove 11, and the second protrusions 3 and the first protrusions 2 are staggered in the extension direction of the wire groove 11. Since the length of the cable that can be fixed by a pair of first protrusions 2 and second protrusions 3 is limited, multiple first protrusions 2 and multiple second protrusions 3 work together to fix a longer length of cable. In a mobile device, this can fix the entire cable, which is conducive to improving the reliability of cable installation.

[0049] Exemplarily, the number of the first protrusions 2 may be two, three, four or more, and correspondingly, the number of the second protrusions 3 may be two, three, four or more, which can be selected in practice according to the specific length of the cable and the fixing effect.

[0050] Optionally, the second protrusion 3 is located between two adjacent first protrusions 2. In this way, the cable located between the two first protrusions 2 will fit more closely to the second protrusion 3 due to its own elastic force, thereby improving the fixing effect of the second protrusion 3 on the cable, which is beneficial to improving the reliability of cable installation.

[0051] In an optional manner, the first protrusion 2 includes a first end 23 and a second end 24 opposite to each other, the first end 23 is connected to the bottom surface 14, and the second end 24 has a first inclined surface 21, and the first inclined surface 21 is inclined from the second end 24 to the first end 23, so that the protruding thickness of the first protrusion 2 gradually increases from the second end 24 to the first end 23. In this way, it can play a guiding role when the cable is clamped by the first protrusion 2 during installation.

[0052] In another optional manner, the second protrusion 3 includes a third end and a fourth end opposite to each other, the third end is arranged opposite to the bottom surface 14, and the fourth end has a second inclined surface 31, and the second inclined surface 31 is inclined from the third end to the fourth end, so that the protruding thickness of the second protrusion 3 gradually increases from the fourth end to the third end. In this way, it can play a guiding role when the cable is clamped by the second protrusion 3 during the installation process.

[0053] Of course, in another optional method, the second end 23 can also have a first slope 21 and the fourth end can have a second slope 31, so that the first slope 21 and the second slope 31 make the width of the opening of the cable trough 11 along the first direction Y greater than the width of the bottom surface 14 along the first direction Y. The first slope 21 and the second slope 31 can play a guiding role in the process of installing the cable from the opening of the cable trough 11 to the space 18, which is conducive to simplifying the cable installation process.

[0054] Optionally, the first protrusion 2 further includes a first clamping surface 22, which is connected to the bottom surface 14 and the first inclined surface 21, respectively. The first clamping surface 22 is inclined, and the inclination direction is the same as the inclination direction of the first inclined surface 21, so that the width of the space 18 along the first direction Y gradually increases from the first end 23 to the second end 24, and the first clamping surface 22 is used to work together with the second side wall 13 to clamp the cable. In this way, when multiple cables with different diameters need to be installed in the space 18, the multiple cables with different diameters can be arranged from small to large according to the cable diameter along the direction from the first end 23 to the second end 24. Since the width of the space 18 formed by the first protrusion 2 and the second protrusion 3 along the first direction Y gradually increases from the first end 23 to the second end 24, each cable can be fixed more firmly by the first clamping surface 22.

[0055] Optionally, the number of the cables may be two, three, four or more, and in practice, the number may be flexibly selected according to specific needs.

[0056] Optionally, the second raised portion 3 further includes a first surface 32 and a second surface 33, wherein the first surface 32 is disposed at the first end 23 and is disposed opposite to the bottom surface 14, and the second surface 33 is respectively connected to the first surface 32 and the second inclined surface 31, and the connection between the second surface 33 and the first surface 32 is an arc transition. Since the cable needs to pass through the connection between the first surface 32 and the second surface 33 during installation in the space 18, if the connection between the first surface 32 and the second surface 33 is not provided with an arc transition, the cable may be scratched, resulting in the cable's energy transmission or information signal transmission function being affected. The use of an arc transition at the connection between the first surface 32 and the second surface 33 reduces the possibility of scratching the cable, thereby improving the yield rate of cable installation.

[0057] Furthermore, the second surface 33 and other surfaces of the second protruding portion 3 connected to the second surface 33 may also be transitioned by arcs, which can further reduce the possibility of the cable being scratched during the installation process.

[0058] See also Figure 2 Optionally, the fixed body 1 includes a first body part 15 and a second body part 16, the first body part 15 and the second body part 16 are connected to form a wire groove 11 therebetween, the first body part 15 has a first side wall 12, the second body part 16 has a second side wall 13, and the connection between the first body part 15 and the second body part 16 forms a bottom surface 14, and the first body part 15 and the second body part 16 are made of different materials. In this way, the first body part 15 and the second body part 16 can be manufactured separately and then assembled. The first body part 15 and / or the second body part 16 are usually manufactured using a mold for injection molding or die casting. When a large number of products are manufactured, the size of the mold itself may become larger, resulting in unstable size of the first body part 15 and / or the second body part 16 produced, affecting the fixing effect of the fixed body 1 on the cable. Therefore, manufacturing the first body part 15 and the second body part 16 separately is conducive to controlling the size of the first body part 15 and the second body part 16, thereby improving the fixing effect of the fixed body 1 on the cable.

[0059] For example, the second body part 16 may be formed by aluminum alloy die casting, and the first body part 15 may be injection molded on the basis of the second body part 16. In this way, since the second body part 16 is used as a reference, the dimensional stability of the first body part 15 may be improved.

[0060] It is understandable that the first main body 15 and the second main body 16 can also be manufactured using other materials, such as steel, non-ferrous metals, resins, engineering plastics, etc. The first main body 15 and the second main body 16 can also be manufactured using other processes, such as various cutting processes, three-dimensional printing, etc. In practice, the selection should be made according to specific needs, and this embodiment does not limit this.

[0061] Optionally, the first main body 15 and / or the second main body 16 are provided with a connecting portion 17, and the connecting portion 17 is used to connect the cable fixing structure 100 and the housing 201. In this way, after the mobile terminal 200 is transferred, the fixing body 1 and the housing 201 of the mobile terminal 200 can be well connected. When the mobile terminal 200 is vibrated or impacted, the fixing body 1 can better protect the cable, which is conducive to improving the reliability of the mobile terminal 200.

[0062] Optionally, the connecting portion 17 includes a plurality of slots 171 and a plurality of tenons 172, the plurality of slots 171 and the plurality of tenons 172 extend along the length direction of the fixed body 1, and the slots 171 and the tenons 172 are alternately arranged along the length direction of the fixed body 1. The slots 171 are arranged on the outer wall surface of the wire groove 11, and the tenons 172 are arranged on the side wall of the wire groove 11, and at least partially protrude from the opening of the wire groove 11. Taking the tenons 171 and the slots 172 arranged on the first sub-portion 15 as an example, the slots 172 are arranged on the outer wall surface of the first sub-portion 15 opposite to the first side wall 12, and are recessed toward the first side wall 12, the tenons 171 are arranged on the first side wall 12, and at least partially protrude from the edge of the first side wall 13 along the second direction X, and the tenons 171 and the slots 172 are alternately arranged. In addition, the tenon 171 and the slot 172 can also be arranged on the second sub-section 16, and the arrangement method is similar to that when they are arranged on the first sub-section 15. The housing 201 of the mobile terminal 200 can also be provided with corresponding connecting tenons and connecting slots corresponding to the slot 171 and the tenon 172 of the connecting portion 17, so that the connection between the fixed body 1 and the housing 201 will be more firm and not easy to be disengaged, which is conducive to further improving the stability of the mobile terminal 200.

[0063] Optionally, the second side wall 13 protrudes at a position corresponding to the connection portion 17 to form a second clamping surface 131, and the second clamping surface 131 is used to cooperate with the tenon 172 to assist in clamping the cable. In this way, the tenon 172 can be structurally reused to improve the utilization efficiency of the tenon 172. At the same time, although the overly dense arrangement of the first protrusion 2 and the second protrusion 3 can improve the reliability of cable fixation, it will increase the difficulty of the process of installing the cable into the space 18. The use of the tenon 172 and the second clamping surface 131 for auxiliary fixation will not only not reduce the fixing effect of the cable, but also help to reduce the difficulty of cable assembly. Based on this, with the cooperation of the tenon 172 and the second clamping surface 131, the number of the first protrusion 3 and the second protrusion 3 can be reduced, and the distance between two adjacent first protrusions 1 can be extended.

[0064] The following is a brief description of the process of fixing the cable by the cable fixing structure 100 of the present application and the process of fixing the cable fixing structure to the housing. The following description takes the cable fixing structure 100 fixing two cables of different diameters as an example:

[0065] S1: Push one end of the cable with the smaller diameter from the first inclined surface 21 to the bottom surface 14 or completely clamped by the first protrusion 2;

[0066] S2: Starting from the fixed end, the cable described in S1 is fixed to the cable duct 11 section by section in the manner described in S1 until the cable is completely fixed to the cable duct 11;

[0067] S3: Push one end of another cable into the cable groove 11 from the second inclined surface 31 toward the bottom surface 14 until the cable segment is fixed by the first protrusion 2 and the second protrusion 3;

[0068] S4: Starting from the fixed end, the cable in S3 is fixed to the cable trough 11 section by section in the manner described in S3 until the cable is completely fixed to the cable trough 11;

[0069] S5: Connect the tenon 171 of the cable fixing structure 100 with the connecting groove of the shell 201 , and connect the slot 172 of the cable fixing structure 100 with the connecting tenon of the shell 201 .

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
