[0048] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0049] like Figure 1-Figure 6 As shown, the present invention provides a cable holder, which includes a first cable winding portion 1, a second cable winding portion 2, a mounting portion 3 and a casing 4, wherein the first cable winding portion 1, the second cable winding portion 2 and the mounting portion 3 are distributed along a first direction, the mounting portion 3 is a mounting base for the other three, the first cable winding portion 1, the second cable winding portion 2 and the casing 4 are all connected to the mounting portion 3, and the casing 4 and the first cable winding portion 1 are located on the same side of the mounting portion 3, so that in the process of using the cable holder, the entire cable holder can be installed or fixed on an installation base such as a wall or an inner wall of an electrical appliance housing with the help of the mounting portion 3, thereby completing the assembly of the entire cable holder.

[0050] In order to ensure that multiple cables 10 can form a reliable connection and fixing relationship with the cable holder, the size of the first winding part 1 can be smaller than the size of the second winding part 2 in at least one second direction perpendicular to the first direction, so that a certain size difference is formed between the first winding part 1 and the second winding part 2, so that when the cable 10 is wound on the first winding part 1, the cable 10 will not slide along the first direction. Accordingly, the second winding part 2 is connected to the mounting part 3. When the cable 10 is wound on the second winding part 2, since the cable 10 is also wound on the first winding part 1 and under the joint action of the limiting part of the mounting part 3, the cable 10 on the second winding part 2 will basically not slide. Therefore, it can be basically ensured that the multiple cables 10 respectively wound on the first winding part 1 and the second winding part 2 can form a reliable relative fixed relationship with the entire cable holder.

[0051] At the same time, the present invention prevents the cable 10 from being loosened by means of the casing 4 arranged on the outside of the second winding part 2 along the third direction around the first direction, and in any second direction, a wire accommodating gap is formed between the casing 4 and the first winding part 1 and the second winding part 2, so that the cable 10 installed in the aforementioned wire accommodating gap can be clamped between the casing 4 and the first winding part 1, and between the casing 4 and the second winding part 2. Accordingly, in order to ensure that the cable 10 can pass through the casing 4 and extend into the aforementioned wire accommodating gap, at least one opening 411 can be formed on the side wall of the casing 4 along the second direction, so that during the process of assembling the cable 10 and the wire fixer, the cable 10 can be inserted into the wire fixer by means of the opening 411, and the cable 10 can also extend from the wire fixer through the opening 411 and be connected to the electrical component. Among them, the opening 411 can be provided with multiple, such as two, three or four, etc., and different cables 10 can be extended into the cable holder from the openings 411 at different positions on the casing 4, and extend from the cable holder from the openings 411 at other positions on the casing 4; in order to reduce the difficulty of threading, preferably, as Figure 2 , Figure 3 and Figure 4 As shown, the casing 4 may be provided with only one opening 411 , and the size of the opening 411 may be relatively large, so that a plurality of cables 10 may extend into the cable holder through the opening 411 , and extend out of the cable holder through the opening 411 .

[0052] Specifically, the first winding part 1, the second winding part 2, the shell 4 and the mounting part 3 can all be formed by integral injection molding of hard materials such as plastic. Of course, the aforementioned four can also be formed by separate molding, and then connected as a whole by hot melting or other methods. Optionally, the aforementioned four can also be made of materials with good insulation properties, so as to prevent the formation of a passage between the cable holder and the cable 10 when the cable 10 is scratched, which will have an adverse effect on the safe use of electricity. In addition, according to the number of cables 10, the structure for winding can be flexibly increased. For example, the winding device provided by the present invention can also include a third winding part, a fourth winding part, a fifth winding part...etc. The arrangement and connection method of the aforementioned parts are similar to the first winding part 1 and the second winding part 2. By changing the respective dimensions in the second direction, different parts can provide winding functions for different cables 10 respectively, which will not be described in detail here.

[0053] The mounting portion 3 may be a plate-shaped or block-shaped structure, and its shape and size may be determined according to factors such as the specific shapes and sizes of the enclosure 4 , the first winding portion 1 , and the second winding portion 2 .

[0054] The approximate shapes of the first winding part 1 and the second winding part 2 can be different or the same. Preferably, the overall shapes of the first winding part 1 and the second winding part 2 can be similar, such as both can be cubes or triangular prisms. On the one hand, it is convenient to process the entire wire fixer. On the other hand, this makes the size of the entire first winding part 1 in any second direction smaller than the size of the second winding part 2, thereby further ensuring that the cable 10 wound on the first winding part 1 is not easy to slide off the first winding part 1, and improving the fixing effect of the wire fixer provided by the present invention on multiple cables 10. More specifically, the size difference between the first winding part 1 and the second winding part 2 in the second direction can be determined according to the actual situation of the cable 10 to be fixed, and is not limited here.

[0055] The enclosure 4 may be a flat plate structure, and a blocking structure may be provided at a position of the enclosure 4 opposite to the mounting portion 3 along the first direction, so as to provide a blocking effect for the cable 10 by means of the blocking structure to prevent the cable 10 from sliding off from the other side of the enclosure 4 away from the mounting portion 3; or Figure 2 , Figure 3 and Figure 4 As shown, the blocking structure may not be provided at the position where the enclosure 4 and the mounting portion 3 are opposite, that is, the enclosure 4 has a cable 10 installation opening on the side away from the mounting portion 3 along the first direction. In the process of installing the cable 10 into the cable holder, the cable 10 can be installed into the wire accommodation gap by means of the aforementioned cable 10 installation opening, which can greatly reduce the difficulty of assembling the cable 10 and the cable holder. Accordingly, the size of the wire accommodation gap between the enclosure 4 and the first winding portion 1 and the second winding portion can also be selected according to actual conditions, and is not limited here.

[0056] It should be noted that the first direction can be Figure 4 The second direction may be direction W, and the third direction may be direction Q. Of course, the aforementioned three are all specific implementations of this embodiment, and the first direction, the second direction and the third direction may also be adjusted accordingly according to actual conditions.

[0057] As can be seen from the above, in the cable holder provided by the present invention, the size of the first winding part 1 in at least one second direction is smaller than the size of the second winding part 2, and in any second direction, there is a wire accommodating gap between the shell 4 and the first winding part 1 and the second winding part 2, so that in the process of fixing the cable 10 with the help of the cable holder, different cables 10 can be wound around the first winding part 1 and the second winding part 2 respectively, and multiple cables 10 are all located in the wire accommodating gap. By fixing different cables 10 at different positions, it can be ensured that multiple cables 10 can form a reliable relative fixed relationship with the entire cable holder. Therefore, the cable holder provided by the present invention can provide a better fixing effect for multiple cables 10.

[0058] Further, as mentioned above, if Figure 2 , Figure 3 and Figure 4 As shown, a cable 10 installation opening can be provided on one side of the casing 4 away from the installation portion 3 along the first direction, so as to facilitate the installation of the cable 10; in order to further prevent the cable 10 from sliding off from the other side of the casing 4 away from the installation portion 3, that is, the cable 10 installation opening, preferably, the cable holder provided by the present invention may also include a positive pressure plate 5, by adding a positive pressure plate 5 at the aforementioned cable 10 installation opening, and forming a detachable connection relationship between the positive pressure plate 5 and the first winding portion 1, in this case, a first wire fixing cavity can be formed between the positive pressure plate 5, the casing 4 and the first winding portion 1, and the cable 10 is accommodated in the first wire fixing cavity, and is limited by the positive pressure plate 5, the casing 4 and the first winding portion 1, so as to prevent the cable 10 from sliding off from the cable 10 installation opening.

[0059] Specifically, the positive pressure plate 5 can also be made of materials such as plastic, and it can be a flat plate structure. Its shape and size can be selected according to the shape of the enclosure 4 and the size of the enclosure 4 in the corresponding direction, so as to ensure that the positive pressure plate 5 can basically cover the wire-accommodating gap between the enclosure 4 and the first winding part 1, so as to further ensure the stability of the relative fixed relationship between the cable 10 and the wire holder without affecting the installation of the cable 10. Optionally, the positive pressure plate 5 and the first winding part 1 can form a relatively fixed relationship through a detachable connection method such as a snap-on, plug-in or threaded connection. Specifically, the positive pressure plate 5 and the first winding part 1 can be respectively provided with corresponding matching snap-on or plug-in structures, so that a relatively fixed relationship can be formed between the positive pressure plate 5 and the first winding part 1; or, the positive pressure plate 5 can also be provided with an external thread (or internal thread), and the corresponding part of the first winding part 1 can be provided with an internal thread (or external thread), which can also ensure that a relatively fixed relationship can be formed between the positive pressure plate 5 and the first winding part 1.

[0060] Preferably, if Figure 1 and Figure 2 As shown, both the positive pressure plate 5 and the first winding part 1 may be provided with threaded holes 51. During the process of assembling the positive pressure plate 5 and the first winding part 1, additional screws 6 may be inserted into the threaded holes 51 on both the positive pressure plate 5 and the first winding part 1, so as to fix the positive pressure plate 5 and the first winding part 1 together. Specifically, the threaded holes 51 on the positive pressure plate 5 and the first winding part 1 may be formed by milling or tapping, and the size of the threaded holes 51 may be adapted according to the size of the screws 6, which is not limited here.

[0061] In order to make the multiple cables 10 in the cable holder form a relatively high fixed relationship with the cable holder, further, as Figure 2 , Figure 5 and Figure 6 As shown, the cable holder provided by the present invention may further include a side pressure plate 7, which is connected to the outer edge of the positive pressure plate 5 along the aforementioned third direction, and a avoidance opening 71 is further provided at the position of the side pressure plate 7 facing the opening 411, so that the cable 10 passes through the avoidance opening 71 and extends into the cable holder; during the process of assembling the cable holder, the side pressure plate 7 is extended into the wire accommodating gap between the first winding part 1 and the surrounding shell 4, at this time, a second wire fixing cavity can be formed between the side pressure plate 7, the second winding part 2 and the surrounding shell 4; at the same time, a relatively closed chamber is formed between the side pressure plate 7, the first winding part 1 and the second winding part 2, and in this embodiment, the aforementioned chamber can be the above-mentioned first wire accommodating cavity, and both the first wire accommodating cavity and the second wire fixing cavity can provide accommodation and fixation for the cable 10.

[0062] Specifically, the shape of the side pressure plate 7 and the size of the side pressure plate 7 in the third direction can be determined according to actual factors such as the shape and size of the enclosure 4 and the shape and size of the first winding part 1. The size of the side pressure plate 7 in the first direction can be determined according to the size of the first winding part 1 in the aforementioned direction, thereby ensuring that in the second direction perpendicular to the first direction, the size of the gap between the side pressure plate 7 and the first winding part 1 meets the use requirements. The side pressure plate 7 and the positive pressure plate 5 can be formed of the same material in an integrally formed manner, which can improve the connection strength and connection reliability between the two. After the positive pressure plate 5 and the side pressure plate 7 form a relatively fixed relationship with the first winding part 1, the side pressure plate 7 can simultaneously provide a limiting effect for the multiple cables 10 wound on the first winding part 1 and the second winding part 2, thereby further improving the matching stability between the multiple cables 10 and the entire cable holder.

[0063] More specifically, the shapes of the enclosure 4 and the side pressure plate 7 can be determined according to the specific shape of the first winding part 1. For example, the shape of the first winding part 1 is a cube, such as a triangular prism, a quadrangular prism or a pentagonal prism. In this case, the enclosure 4 and the side pressure plate 7 can be a broken line structure. Preferably, the first winding part 1 can be a cylindrical structure, which can reduce the probability of damage to the cable 10 by the surface of the first winding part 1 during the winding process of the cable 10. At this time, the enclosure 4 and the side pressure plate 7 can be cylindrical side structures. On the one hand, it can ensure that the enclosure 4 and the side pressure plate 7 have a high degree of tightness when they are matched. On the other hand, it can also ensure that the spacing between the side pressure plate 7 and the first winding part 1 at any corresponding position is basically equal, so as to facilitate the installation of the cable 10. In this case, the centers of the enclosure 4, the side pressure plate 7 and the first winding part 1 can be located on the same straight line to further optimize the matching relationship between the three.

[0064] Optionally, the casing 4 may include multiple parts, one of which may be a baffle 41, and the baffle 41 may be a cylindrical side structure. The opening 411 is arranged on the baffle 41, so as to ensure that the cable 10 can be inserted into the cable holder and extend out of the cable holder; the center of the baffle 41 is on the same line as the center of the first winding part 1, and the baffle 41 is arranged on the outside of the side baffle 41, and the side baffle 41 is wound on the outside of the first winding part 1. In order to prevent the cable 10 from extending out of the opening 411 from the wire clearance gap and causing damage to the enameled wire of the cable 10 due to the large pressure exerted on the cable 10 by the end of the baffle 41, preferably, the casing 4 may also include a guide plate 42, which is an arc-shaped structure and is connected to the end of the baffle 41. By extending the guide plate 42 in a direction away from the first winding portion 1, the guide plate 42 can provide guidance for the cable 10 extending out of the opening 411, and since the guide plate 42 is an arc-shaped structure, the entire wire holder can be prevented from damaging the cable 10.

[0065] Specifically, the baffle 41 and the guide plate 42 can be formed by integral molding using the same material, and the guide plate 42 can be a circular arc structure, or can also be an elliptical arc structure. The degree of curvature of the guide plate 42 can be determined according to actual conditions, and along the first direction, the size of the guide plate 42 can be equal to the size of the baffle 41, and the size of the baffle 41 can be slightly larger than the sum of the sizes of the first winding part 1 and the second winding part 2 in the first direction, so that after the positive pressure plate 5 is installed, the surface of the positive pressure plate 5 can be basically flush with the upper surface of the baffle 41 to prevent foreign objects from hitting the positive pressure plate 5 and destroying the fixed relationship between the positive pressure plate 5 and the first winding part 1. In addition, the enclosure 4 can also include other parts, such as the other end of the guide plate 42 can be connected to a flat plate structure. During the actual use of the cable holder, the installation direction and position of the cable holder can be changed according to the direction of the cable 10, so as to guide the cable 10 with the help of the guide plate 42 and the aforementioned flat plate structure, and further improve the fixing effect of the cable 10.

[0066] In order to increase the friction between the cable 10 and the first winding part 1 and the second winding part 2 and prevent the cable 10 from moving along the surfaces of the first winding part 1 and the second winding part 2 when an external force is applied, preferably, anti-slip protrusions 11 are provided on the surfaces of the first winding part 1 and the second winding part 2 along the third direction. During the use of the cable holder, the cable 10 is assembled into the cable accommodating gap, and a certain force is applied to the cable 10 to make it contact with the anti-slip protrusions 11, so that under the action of the anti-slip protrusions 11, the stability of the relatively fixed relationship between the cable 10 and the cable holder is further improved.

[0067] Specifically, the anti-slip protrusion 11 can be a point-shaped structure, or the anti-slip protrusion 11 can also be a strip-shaped structure, which can extend along the first direction or other directions inclined relative to the first direction. The anti-slip protrusion 11 with a strip-shaped structure can provide a more comprehensive anti-slip effect for the cable 10. The protruding size of the anti-slip protrusion 11 can be determined according to actual conditions, and its size should not be too large to prevent the cable 10 from exerting too much force on the anti-slip protrusion 11 and damaging the anti-slip protrusion 11. In addition, the protruding size of the anti-slip protrusion 11 should not be too small to prevent the anti-slip protrusion 11 from losing its basic function.

[0068] Preferably, a plurality of anti-skid protrusions 11 may be provided on both the first winding portion 1 and the second winding portion 2, and the plurality of anti-skid protrusions 11 may be uniformly and spaced apart along the third direction, thereby further improving the fixing effect of the cable 10 with the aid of the plurality of anti-skid protrusions 11. The structures and sizes of the plurality of anti-skid protrusions 11 may be the same, and the plurality of anti-skid protrusions 11 may be integrally formed during the formation process of the first winding portion 1 and the second winding portion 2.

[0069] In order to further improve the fixing effect of the cable 10, preferably, the cable holder provided by the present invention may also include a limit plate 8, which is connected to the outer edge of the second winding part 2 along the third direction, and the limit plate 8 extends relative to the second winding part 2 along the first direction in a direction away from the mounting part 3, so that the limit plate 8 and the first winding part 1 can form a wire accommodating space, and the cable 10 can be limited and set in the aforementioned wire accommodating space, and in any second direction, the limit plate 8 and the first winding part 1 can provide a limiting effect on the limited position; and, in order to prevent the existence of the limit plate 8 from having an adverse effect on the insertion and extension of the cable 10, a notch 81 is further provided at the position of the limit plate 8 facing the opening 411, and during the installation of the cable 10, the cable 10 can extend into the cable holder from the notch 81, and can extend from the cable holder through the notch 81.

[0070] Specifically, the limit plate 8 can be formed integrally with the first winding part 1 and the second winding part 2, and the size of the limit plate 8 in the first direction can be determined according to actual conditions, and the size of the notch 81 in the third direction can be determined according to the size of the opening 411 in the third direction. For example, when the baffle 41 and the side pressure plate 7 are both cylindrical side structures, the limit plate 8 can also be a cylindrical side structure. If the angle corresponding to the opening 411 is 60°, the angle corresponding to the notch 81 can also be 60°, and the position of the notch 81 corresponds to the opening 411, thereby forming a stable matching relationship between the cable 10 and the wire holder.

[0071] Furthermore, the cable holder provided by the present invention may also include an anti-rotation portion 9. Along the first direction, the anti-rotation portion 9 is connected to the side of the positive pressure plate 5 facing the first winding portion 1, and the anti-rotation portion 9 also extends into the notch 81. After the positive pressure plate 5 and the first winding portion 1 form a relatively fixed relationship, the positive pressure plate 5 can be prevented from rotating when subjected to external force by means of the limiting matching relationship formed by the anti-rotation portion 9 and the limiting plate 8, thereby further ensuring a relatively high fixed relationship between the positive pressure plate 5 and the first winding portion 1, and thereby maintaining a good fixed relationship between the cable 10 installed in the cable accommodating space and the entire cable holder.

[0072] Specifically, the anti-rotation portion 9 can be integrally formed during the formation process of the positive pressure plate 5, and the anti-rotation portion 9 can also be interconnected with the side pressure plate 7, and it is located at the position of the avoidance opening 71 on the side pressure plate 7. The anti-rotation portion 9 can be a plate-like structure, which can be connected to the two ends of the side pressure plate 7, and a through structure is provided relative to the avoidance opening 71, thereby ensuring that the cable 10 can still be extended into the wire holder through the avoidance opening 71, and the cable 10 can also be extended from the wire holder.
