[0003] However, for some scenarios, such as in-vehicle applications in special environments or industry applications, the cost of using customized charging and data transmission cables is too high; if general cables are used, the compatibility between the cable plug and the interface on the host is generally poor, and the cable plug is prone to loosening or falling off, affecting the performance.

[0004] Therefore, in view of the above-mentioned technical problems, how to improve the fixed connection effect between the plug of the general cable and the host interface is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a cable assembly fixing device that can press the plug of the cable assembly into the interface to ensure that the plug is not easily loosened or detached.

[0006] To achieve the above objectives, this application provides a cable assembly fixing device, including a fixing block. The fixing block has a receiving groove with an opening on one side. The cable assembly enters the receiving groove through the opening. The receiving groove includes a first receiving groove for accommodating a plug of the cable assembly. One end of the first receiving groove passes through the fixing block. The plug extends out of the first receiving groove and is inserted into the interface of the host. The other end of the first receiving groove has a protrusion. In the insertion direction of the plug, the protrusion abuts against the plug and limits its movement. The fixing block is fixedly connected to the host. After the two are fixedly connected, the protrusion provides a clamping force to press the plug against the interface.

[0007] Preferably, the receiving groove further includes a second receiving groove disposed on the protrusion, one end of the second receiving groove communicating with the first receiving groove, and the other end of the second receiving groove passing through the protrusion, and the second receiving groove is used to receive the wire of the cable assembly.

[0008] Preferably, the opening covers the first receiving groove and the second receiving groove, and the width of the opening is greater than or equal to the wire diameter of the wire body, but less than the width of the plug.

[0009] Preferably, the first receiving groove is adapted to the outer contour of the plug.

[0010] Preferably, the fixing block has a fixing hole, and the fixing block is detachably connected to the main unit through a screw inserted in the fixing hole.

[0011] Preferably, the number of fixing blocks is at least two, the two fixing blocks having the opening side fit together, and the two first receiving slots are correspondingly combined to wrap the plug.

[0012] Preferably, the first fixing block is provided with a limiting block that protrudes towards the second fixing block, the second fixing block is provided with a limiting groove corresponding to the limiting block, and the second fixing block is provided with a fixing hole that penetrates the limiting block.

Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, in this embodiment, a cable assembly fixing device is provided. The cable assembly 3 includes a plug 31 and a wire 32 connected to the plug 31. Generally, the size of the plug 31 is larger than the size of the wire 32. The fixing device of this application can be used for various general-purpose cable assemblies 3 that meet the above requirements. The fixing device includes a fixing block 1, which has a receiving groove with an opening 14 on one side. The cable assembly 3 can enter the receiving groove through the opening 14. Since the cable assembly 3 is a general-purpose cable, no customized modification is required. It can cooperate with the fixing device of this application. The fixing block 1 fastens the plug 31, thereby achieving a stable connection between the plug 31 and the interface on the host. Of course, when the cable assembly 3 does not need to be connected to the host, the cable assembly 3 can also be removed from the fixing block 1 through the opening 14, making disassembly convenient.

[0031] Please refer to Figure 2 The receiving groove includes a first receiving groove 11 for accommodating the plug 31. One end of the first receiving groove 11 passes through the fixing block 1, and the plug 31 extends out of the first receiving groove 11 through the passing end, thereby correspondingly plugging into the interface of the host. A protrusion 13 is provided at the other end of the first receiving groove 11. The protrusion 13 can abut against the end of the plug 31. Specifically, in the insertion direction of the plug 31, the protrusion 13 abuts against the root of the plug 31, so that after the fixing block 1 is fixedly connected to the host, the protrusion 13 can provide a clamping force to press the plug 31 against the host, thereby ensuring that the plug 31 is stably plugged into the interface and is not easy to loosen or fall off. Here, the end of the plug 31 refers to the end that is plugged into the interface; the root of the plug 31 refers to the end that is connected to the wire 32.

[0032] In summary, this application provides a receiving groove with an opening 14 on the fixing block 1. The cable assembly 3 can enter the receiving groove through the opening 14. Without requiring customized modifications to the general cable, the fixing block 1 can be used to achieve a stable connection between the plug 31 and the interface on the host. Specifically, the receiving groove includes a first receiving groove 11. After the cable assembly 3 enters the receiving groove, the plug 31 of the cable assembly 3 can also enter the first receiving groove 11. One end of the plug 31 extends out of the first receiving groove 11 and is inserted into the interface of the host. A protrusion 13 is provided at the other end of the plug 31 in the first receiving groove 11. In the insertion direction of the plug 31, the protrusion 13 can limit and abut against the plug 31. Thus, after the fixing block 1 is fixed to the host, the protrusion 13 can provide pressure on the plug 31 against the host, thereby ensuring that the plug 31 is stably installed at the interface. The fixing device of this application has a simple structure and is easy to use. It is applicable to various cable assemblies 3 with plugs 31 and wires 32, has a wide range of applications, and provides good fixing effect.

[0033] In some embodiments, since the root of the plug 31 is connected to the wire 32, in order to avoid interference between the protrusion 13 and the wire 32 at the root of the plug 31, a second receiving groove 12 can be provided on the protrusion 13. Please refer to... Figure 2 and Figure 3 One end of the second receiving groove 12 is connected to the first receiving groove 11, which satisfies the requirement that the receiving groove can simultaneously accommodate the plug 31 and part of the wire 32, so that the cable assembly 3 can be smoothly matched with the fixing block 1; the other end of the second receiving groove 12 passes through the protrusion 13, ensuring that the wire 32 can be smoothly exited on the fixing block 1.

[0034] In one embodiment, the fixing device of this application can be as follows: Figure 2 The integrated fixing device shown, namely a single fixed block 1, can fix the plug 31 and can easily insert or remove the cable assembly 3. Specifically, the opening 14 on one side of the receiving groove can cover the first receiving groove 11 and the second receiving groove 12. At the same time, the width of the opening 14 is greater than or equal to the wire diameter of the cable body 32 and less than the width of the plug 31. Since the opening 14 is greater than or equal to the diameter of the wire 32, when placing the cable assembly 3 into the receiving groove, the wire 32 can first be placed into the first receiving groove 11 and the second receiving groove 12 through the opening 14. With one end of the first receiving groove 11 through, the wire 32 can be pulled to make the plug 31 slide into the first receiving groove 11. The plug 31 gradually slides into the receiving groove through the through end of the first receiving groove 11 along the pulling direction of the wire 32 until it slides until the plug 31 abuts against the protrusion 13. Furthermore, since the width of the opening 14 is less than the width of the plug 31, the first receiving groove 11 can limit the plug 31 in the radial direction to prevent the plug 31 from accidentally coming out of the first receiving groove 11.

[0035] It should be noted that the shape of the first receiving groove 11 is not subject to many restrictions and can be a cylindrical groove, a square groove, an irregular groove, etc., so it can be incorporated into the plug 31 of various general-purpose cable assemblies 3. In some embodiments, the first receiving groove 11 can be adapted to the outer contour of the plug 31, and when the plug 31 is located in the first receiving groove 11, the outer wall of the insulating sheath of the plug 31 can fit against the groove wall of the first receiving groove 11, so that the plug 31 can be more stably set in the first receiving groove 11.

[0036] Furthermore, the material of the fixing block 1 is not limited. For example, it can be made of soft materials such as plastic or rubber, or harder materials such as glass fiber, metal, or composite materials. Its processing methods, such as 3D printing, injection molding, or machining, are all acceptable, without excessive restrictions. The surface finish, shape, and size of the fixing block 1 are not limited, as long as it has a receiving groove to enclose the plug 31 and provides a clamping force for the plug 31 to press against the host, all of which fall within the protection scope of this application.

[0037] It should be noted that for fixing blocks 1 made of softer materials, the size of the opening 14 will change due to compression. That is, when the width of the opening 14 is slightly smaller than the width of the plug 31, the plug 31 can be pressed directly into the first receiving groove 11 through the opening 14 by pressing. During the process of pressing the plug 31 into the opening 14, the plug 31 will compress the opening 14 to a certain extent, and after being pressed into the first receiving groove 11, the size of the opening 14 will return to its initial state. In the initial state, the first receiving groove 11 can still radially limit the plug 31, preventing the plug 31 from accidentally coming out of the first receiving groove 11 from the opening 14. The above method is only applicable to fixing blocks 1 made of softer materials. Because rigid fixing blocks 1 do not have elastic deformation properties, the plug 31 cannot be directly pressed into the first receiving groove 11 through the opening 14 by pressing, as this may easily damage the plug 31 or the fixing block 1.

[0038] In addition, fixing holes 15 are provided on fixing block 1, please refer to Figure 2 The fixing block 1 can be detachably connected to the main unit via a screw 2 passing through the fixing hole 15. The main unit has screw holes corresponding to the fixing hole 15. The size and depth of the screw holes are not limited, and the method of screw holes being tapped or embedded is not limited. Their function is to provide a force point so that the fixing block 1 can be fixed to the main unit. The number of screw holes is also not limited; one, two, three, or more are all acceptable, as long as they can be aligned with the fixing hole 15 on the fixing block 1. The size of the fixing hole 15 is also not limited. The end of the fixing hole 15 may have an enlarged hole to facilitate the insertion of the screw 2 or the placement of a spring washer on the screw 2, or it may not have an enlarged hole.

[0039] As for screw 2, its quantity is the same as that of fixing block 1, and its material and thread length are not limited. There are no restrictions on the additions to screw 2 (e.g., via...). Figure 5 The spring in Figure 6 (With auxiliary materials such as washers), after all the necessary accessories for screw 2 are assembled, screw 2 obtains a force pointing towards the host through the thread of the screw hole on the host. This force is transmitted to the fixing block 1 through the nut. If there is a spring or washer, it is transmitted to the fixing block 1 through the spring and washer. The protrusion 13 on the fixing block 1 then transmits the force to the plug 31 of the cable assembly 3, so the plug 31 obtains a force towards the host, thereby achieving a stable plug-in effect. The clamping force provided by the protrusion 13 can be adjusted according to the tightening of screw 2, so as to obtain different preloads according to the actual situation of plug 31, ensuring that different types of plugs 31 can be adapted to the fixing device.

[0040] In another embodiment, the fixing block 1 may also be a fixing device composed of two or more components, please refer to Figure 4 Two or more fixing blocks 1 are brought close together and fitted together on one side of the opening 14. For example, when two fixing blocks 1 are joined together, they enclose the cable assembly 3. When separated, the cable assembly 3 can be released. After the fixing blocks 1 are fitted together, the positions of the first receiving grooves 11 on the fixing blocks 1 are aligned accordingly, and the positions of the second receiving grooves 12 are aligned accordingly, so that the two first receiving grooves 11 form a groove structure to enclose the plug 31. Similarly, the two second receiving grooves 12 also form a groove structure to enclose the cable 32.

[0041] Based on this, a limiting block 16 is provided on the first fixing block 1, which protrudes towards the second fixing block 1. Please refer to... Figure 4 The second fixing block 1 is provided with a limiting groove corresponding to the limiting block 16. The second fixing block 1 is provided with a fixing hole 15 that passes through the limiting block 16. The two fixing blocks 1 are detachably connected to the main unit through screws 2 passing through the fixing holes 15. The screws 2 here are set in the same way as the screws 2 mentioned above, without too many restrictions. The first fixing block 1 and the second fixing block 1 can be equivalently interchanged, or both can be provided with limiting blocks 16 and limiting grooves to ensure that the screws 2 can be connected to the main unit after passing through the two fixing blocks 1 in sequence. All of these fall within the protection scope of this application.

[0042] After the screw 2 passes through the second fixing block 1 and the limiting block 16 of the first fixing block 1, the two fixing blocks 1 can be connected in a limiting manner. The screw 2 is fixed to the host, so that the two fixing blocks 1 are relatively fixed and finally fixed on the host. The protrusions 13 on the two fixing blocks 1 simultaneously limit and squeeze the end of the plug 31, so that the plug 31 is stably plugged into the interface.

[0043] It should be noted that, based on the combination of the two fixing blocks 1 to form the fixing device, the opening 14 can still cover the first receiving groove 11 and the second receiving groove 12, and the opening 14 includes a first opening segment with a width greater than or equal to the width of the plug 31 and a second opening segment with a width greater than or equal to the wire diameter of the wire body 32. The plug 31 can be directly put into the first receiving groove 11 through the first opening segment. Similarly, the wire body 32 can also be put into the second receiving groove 12 through the second opening segment. The two fixing blocks 1 are combined to form a receiving groove that wraps the cable assembly 3.

[0044] Similarly, after the two fixing blocks 1 are combined, the groove structure formed by the two corresponding first receiving grooves 11 on the two fixing blocks 1 is adapted to the outer contour of the plug 31, preventing the plug 31 from shaking randomly in the groove structure and improving the stability of the plug 31; the groove structure formed by the two corresponding second receiving grooves 12 on the two fixing blocks 1 is adapted to the outer contour of the cable 32, preventing the cable 32 from shaking randomly in the groove structure, thereby improving the overall stability of the cable assembly 3 on the fixing blocks 1 and ensuring the stable plug-in effect of the plug 31 and the structure.

[0045] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0046] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
