[0002] As an important component for electric energy transmission, when cables are used inside power equipment, cable fixing structures are often installed at the cable interfaces of the equipment to fix and lock the cables, prevent them from moving, and enhance the safety of cable laying. However, previous cable fixing structures are only suitable for fixing cables with small and medium cross-section sizes.

[0003] Since there is often no suitable cable fixing structure available for laying large-sized cables, in order to connect cables with larger cross-sections to power equipment with higher power, cable protection sleeves or wire loops are usually used to install cables, but there are problems such as insufficient locking force, low firmness, weak impact resistance, and poor safety and stability. At the same time, the wiring ports of cables with multiple specifications and large cross-sections lack suitable fixing structures. Changes in cable specifications can easily lead to reprocessing and reselection of wiring ports and related fixing structures of power equipment, resulting in low production efficiency and waste of resources.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] In order to solve the problem that the existing cable fixing device cannot meet the cable fixing problem at the wiring port when laying cables of multiple specifications and large cross-sections in the power box, according to the embodiment of the utility model, a cable fixing device is provided. The cable fixing device of the utility model will be described in detail below with reference to the accompanying drawings.

[0042] See also Figures 1 to 7 As shown, according to a first embodiment of the present invention, a cable fixing device is provided. The cable fixing device includes a first locking member 10 , a second locking member 20 and an elastic locking portion 30 .

[0043] The first locking member 10 includes a fixing portion 11 and a first receiving portion 12 disposed on the fixing portion 11, and the fixing portion 11 is used to fix the first locking member 10 on the predetermined structure 51. The second locking member 20 includes a second receiving portion 22, and the second receiving portion 22 is detachably connected to the first locking member 10 through a connecting member 40, and the second receiving portion 22 and the first receiving portion 12 are surrounded to form a wire-passing hole 13. The elastic locking portion 30 is disposed in the wire-passing hole 13, and the elastic locking portion 30 includes a plurality of elastic locking rings 31, and the plurality of elastic locking rings 31 are nested and detachable.

[0044] In the present invention, the first locking member 10 is fixed to the predetermined structure 51 through the fixing portion 11. The fixing portion 11 and the predetermined structure 51 can be connected by welding, bolt connection, snap connection and other connection methods. The first embodiment of the present application shows the situation that the fixing portion 11 and the predetermined structure 51 are connected by welding. When using the cable fixing device, first, the first locking member 10 is fixed to the predetermined structure 51 through the fixing portion 11. Then the second locking member 20 is installed on the first locking member 10, so that the first accommodating portion 12 on the first locking member 10 and the second accommodating portion 22 on the second locking member 20 can be surrounded to form a wire passing hole 13. Finally, the elastic locking portion 30 composed of a plurality of elastic locking rings 31 is installed in the wire passing hole 13, and the cable (not shown in the figure) can pass through the elastic locking ring 31. Finally, the cable is clamped and fixed to the predetermined structure 51 by the first locking member 10 and the second locking member 20. Since the elastic locking portion 30 is composed of a plurality of detachable elastic locking rings 31 , it is applicable to cables with different cross-sectional sizes.

[0045] That is to say, compared with the cable fixing device in the prior art, the cable fixing device in this embodiment is suitable for the installation and fixing of cables with different large cross-sectional sizes during the laying process.

[0046] Further, see Figure 5 As shown, the fixing portion 11 includes a first arc portion 113 and fixing brackets disposed at both ends of the first arc portion 113. The fixing bracket includes a first fixing bracket 111 and a second fixing bracket 112. The first arc portion 113 is connected between the first fixing bracket 111 and the second fixing bracket 112. The first arc portion 113 has a first arc groove, and the first arc groove forms a first accommodating portion 12.

[0047] Specifically, the first fixing bracket 111 and the second fixing bracket 112 are respectively located at the two ends of the first arc-shaped portion 113 and connected to the first arc-shaped portion 113. The first fixing bracket 111, the first arc-shaped portion 113 and the second fixing bracket 112 can be welded or can be formed by cutting and bending a whole piece of material to form a whole, that is, the first locking member 10. Compared with the prior art, such an integrated molding structure makes the first locking member 10 more durable when in use, and also makes the processing more convenient. The first arc-shaped groove on the first arc-shaped portion 113 forms the first accommodating portion 12. The first accommodating portion 12 adopts an arc-shaped structure design in order to better fit the outer surface of the cable when in use, so as to better fix the cable when laying the cable. This embodiment shows the situation when the first accommodating portion 12 is arc-shaped. For some special occasions, the structure of the first accommodating portion 12 can be adjusted according to the outer surface structure of the cable, and can be a rectangular, wavy, etc. structure. As for the other structural designs of the first accommodating portion 12, as long as they are designed to make the first accommodating portion 12 fit more closely with the outer surface of the cable, they are also within the scope of protection required by the present application.

[0048] Further, see Figure 1 and Figure 5 As shown, the first fixed bracket 111 and the second fixed bracket 112 each include a fixed plate 1111, a support plate 1112 and a connecting plate 1113 which are vertically connected in pairs. The first fixed bracket 111 and the second fixed bracket 112 are symmetrically arranged at both ends of the first arc-shaped portion 113, and the connecting plate 1113 is connected to the first arc-shaped portion 113. The fixed plate 1111 is used to be fixedly connected to the predetermined structure 51.

[0049] Specifically, the first fixed bracket 111 and the second fixed bracket 112 are symmetrical about the first arc-shaped portion 113, and the fixed plate 1111, the support plate 1112 and the connecting plate 1113 are vertically connected to each other to form an unclosed cavity. The fixed plate 1111 and the support plate 1112 can be manufactured separately and then welded to the connecting plate 1113, or can be obtained by bending the extended portion of the connecting plate 1113. The present application shows the case where the fixed plate 1111 and the support plate 1112 are obtained by bending the extended portion of the connecting plate 1113. The fixed plate 1111 and the support plate 1112 can be connected or not connected. When the fixed plate 1111 and the support plate 1112 are connected, the fixed plate 1111 and the support plate 1112 can be connected by welding or clamping. The present application shows the case where the fixed plate 1111 and the support plate 1112 are connected by welding. The reason why the fixing plate 1111, the supporting plate 1112 and the connecting plate 1113 are designed to be perpendicular to each other is to make the structure of the fixing part more stable and more able to withstand force when in use.

[0050] Further, see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown in FIG. 1 , a first connection hole 1114 is provided on the connection plate 1113, a second connection hole 214 is provided on the second locking member 20, and a connection member 40 is detachably inserted into the first connection hole 1114 and the second connection hole 214 to fix the first locking member 10 and the second locking member 20. The connection member 40 can be a screw and nut connection with a threaded connection, or a bolt and nut connection with a threaded connection, or a structure with locking and anti-loosening functions similar to a cable tie, so that the distance between the first locking member 10 and the second locking member 20 can be adjusted to adapt to cables with different cross-sectional sizes.

[0051] Furthermore, the first connection hole 1114 and the second connection hole 214 include waist-shaped holes, which extend from the first fixing bracket 111 to the second fixing bracket 112. The directions of the waist-shaped holes are perpendicular to the axes of the first arc-shaped portion 113 and the second arc-shaped portion 212 (not shown in the figure), and the waist-shaped holes can be set as one or more groups. One or more groups of waist-shaped holes must meet the requirements that when the first locking member 10 and the second locking member 20 fix the cable, the first locking member 10 and the second locking member 20 will not tilt to the other side, thereby causing unreliable fixation.

[0052] Further, see Figure 4 , Figure 6 as well as Figure 7 As shown, the second locking member 20 includes a second arc-shaped portion 212 and connecting portions arranged at both ends of the second arc-shaped portion 212, the connecting portions include a first connecting portion 211 and a second connecting portion 213, the second arc-shaped portion 212 is connected between the first connecting portion 211 and the second connecting portion 213, and the second arc-shaped portion 212 has a second arc-shaped groove, and the second arc-shaped groove forms the second accommodating portion 22.

[0053] Specifically, the first connection part 211 and the second connection part 213 are respectively located at the two ends of the second arc-shaped part 212 and connected to the second arc-shaped part 212. The first connection part 211, the second connection part 213 and the second arc-shaped part 212 can be manufactured separately and then welded into a whole, or they can be stamped from a whole plate. This embodiment shows the situation where the first connection part 211, the second connection part 213 and the second arc-shaped part 212 are stamped into a whole. The second arc-shaped groove on the second arc-shaped part 212 forms the second accommodating part 22. The second accommodating part 22 adopts an arc-shaped structure design to better fit the outer surface of the elastic locking ring 31 when in use, and the elastic locking ring 31 is sleeved on the outer surface of the cable, so as to better fix the cable when laying the cable. The first embodiment of the present application shows the situation when the second accommodating part 22 is an arc. For some special occasions, the structure of the second accommodating part 22 can be adjusted according to the outer surface structure of the cable, which can be a rectangular, wavy and other structures. As for the structural designs of the remaining second accommodating portions 22 , as long as they are designed to make the second accommodating portions 22 fit more closely to the outer surface of the cable, they are also within the scope of protection required by the present application.

[0054] Further, see Figures 6 to 11 As shown, the second embodiment of the present application shows another situation of the cable fixture. Among them, the cable fixture shown in the second embodiment has most of the same technical features as the cable fixture shown in the first embodiment. The difference is that: a notch 221 is provided on the side wall of the first accommodating portion 12 and / or the second accommodating portion 22, and when the cable fixture is fixed on the first side wall 511 of the predetermined structure 51, the notch 221 is located on the side of the cable fixture close to the first side wall 511. The elastic locking ring 31 has an annular outer flange 311, which is at least partially inserted into the notch 221 and is pressed and fixed by the first locking member 10 and / or the second locking member 20.

[0055] Specifically, the second embodiment shows that the side walls of the first accommodating portion 12 and the second accommodating portion 22 are both provided with a notch 221. In addition, the cable fixing device shown in the second embodiment is suitable for using an elastic locking ring 31, and the elastic locking ring 31 has an annular outer flange 311. When the cable fixing device is installed on the first side wall 511 of the predetermined structure 51, the first locking member 10 and the second locking member 20 cooperate to form an annular notch 221. When the elastic locking ring 31 is inserted between the first locking member 10 and the second locking member 20, the annular outer flange 311 can cooperate with the annular notch 221, and the elastic locking ring 31 can be pressed and fixed by the first locking member 10 and the second locking member 20 through the annular outer flange 311, and then when the cable is inserted into the elastic locking ring 31, the elastic locking ring 31 can be pressed and fixed to the predetermined structure 51.

[0056] Further, see Figure 6 and Figure 7 As shown, in the cable fixing device shown in the first embodiment of the present application, for cables of multiple specifications, the elastic locking portion 30 further includes a plurality of coaxially arranged elastic locking rings 31, and in two adjacent elastic locking rings 31, the inner periphery of the end of the elastic locking ring 31 located on the outer side is provided with an annular limiting groove 312, and the annular limiting groove 312 is coaxially arranged with the elastic locking ring 31, and the outer periphery of the end of the elastic locking ring 31 located on the inner side is provided with an annular outer flange 311, and the annular outer flange 311 is coaxially arranged with the elastic locking ring 31 and is adapted to the annular limiting groove 312. Among the plurality of elastic locking rings, the elastic locking ring located on the outermost side has an annular outer flange 311, and a through hole is provided on the predetermined structure, the elastic locking ring located on the outermost side is penetrated in the through hole, and the annular outer flange 311 is stopped on the second side wall of the through hole opposite to the first side wall.

[0057] Specifically, when the cable fixing device is used to fix the cable, since the elastic locking ring 31 is designed as a nested structure, and the annular limiting groove 312 and the annular outer flange 311 are cleverly designed, the axial movement and circumferential movement between the elastic locking rings 31 can be effectively prevented. When the cable is inserted into the elastic locking ring 31, the cable can be further prevented from moving in the circumferential and axial directions. When the outermost elastic locking ring 31 is inserted into the cable fixing device by the second side wall 513 of the predetermined structure, the annular outer flange 311 on the outermost elastic locking ring 31 can limit the elastic locking ring 31 from entering the predetermined structure through the through hole 512. In the cable fixing device of the present application, the elastic locking ring 31 can be a single or multiple nested design. The first embodiment of the present application shows the situation when three elastic locking rings 31 are nested with each other.

[0058] Furthermore, the side wall thickness of the elastic locking ring 31 is 3 mm to 10 mm. Because the elastic locking ring 31 needs to meet the requirements of cables with different cross-sectional sizes, if the side wall thickness is too thin, the number of elastic locking rings 31 will increase, which will reduce the stability of the elastic locking rings 31 when they are nested. In addition, the elastic locking ring 31 with too thin side wall thickness is easily damaged and is not conducive to the processing of the structure of the elastic locking ring 31 of the present application. The elastic locking ring 31 with too thick side wall thickness will not be able to better adapt to the installation of cables with different cross-sectional sizes. At the same time, the elastic locking ring 31 with too thick side wall thickness will also make the overall size of the cable fixing device larger. After actual experiments and inquiries about the changes in the cross-sectional size of the cable, the side wall thickness of the elastic locking ring 31 is set to 3 mm to 10 mm, such as 3 mm, 5 mm, 7 mm, 9 mm, 10 mm, etc.

[0059] On the other hand, see Figure 1 , Figure 2 , Figure 8 as well as Fig. 9 As shown, the present application also provides a power box 50, which includes the cable fixing device mentioned in the present application. After the cable fixing device is installed inside the power box 50, when laying cables in the power box 50, the cables can be clamped and fixed to prevent the cables from moving circumferentially and axially relative to the power box 50.

[0060] Further, see Figure 1 , Figure 2 , Figure 6 , Figure 8 as well as Fig. 9 As shown, the power box 50 includes a box body, which forms a predetermined structure 51 , a through hole 512 is provided on a first side wall 511 of the box body, and a cable fixing device is provided inside the box body, and the through hole 512 corresponds to the wire hole 13 .

[0061] Specifically, after the cable fixing device is installed on the first side wall 511 of the box, the through hole 512 can correspond to the wire hole 13, and the arc surface of the first arc portion 113 is flush with the hole edge of the through hole 512, so that the through hole 512 can be utilized to the maximum extent.

[0062] Further, see Figures 1 to 3 As shown, in the first embodiment of the present application, the power box 50 also includes a baffle 52, which is arranged on the outside of the box body, and a wire passing opening 53 is provided on the baffle 52, and the wire passing opening 53 corresponds to the wire passing hole 13, and the baffle 52 stops at the end of the annular outer flange 311 and the annular outer flange 311 of the elastic locking ring 31.

[0063] Specifically, the baffle 52 is installed on the second side wall 513 of the box body, and the baffle 52 and the second side wall 513 can be connected by screw connection, snap connection, welding and other methods. This embodiment shows the situation when the baffle 52 and the second side wall 513 are connected by screws. In this case, multiple screw holes can be set on the outer periphery of the baffle 52 for installing screws and nuts. Correspondingly, screw holes are also provided at positions corresponding to the screw holes on the second side wall 513 of the box body, so that the baffle 52 can be fixed on the second side wall 513 of the box body. In this way, the elastic locking rings 31 nested in layers can be prevented from falling off from the through holes 512 on the second side wall 513 of the box body. The shape of the baffle 52 can be regular shapes such as square, rectangular and circular, or irregular shapes, as long as the elastic locking rings 31 nested in layers can be prevented from falling off from the through holes 512 on the second side wall 513 of the box body. The first embodiment shows the case where the baffle 52 is a square. Other regular or irregular shapes of the baffle 52, such as rectangles and circles, are all within the scope of protection claimed in the present application.

[0064] From the above statements, it can be known that: the present application relates to the technical field of installing and laying cable harnesses for chassis, cabinets and other products in the power industry, specifically a cable fixing device and a power chassis, including a cable fixing device composed of a first locking member 10, a second locking member 20 and an elastic locking portion 30. First, the first locking member 10 is fixed to the through hole 512 of the second side wall 513 of the box body by welding, and then the second locking member 20 is installed on the first locking member 10 and forms a wire hole 13 together with the first locking member 10, and the second locking member 20 is pressed and locked on the first locking member 10 through the connecting member 40. Finally, the nested elastic locking rings 31 are installed in the through hole 512 of the box body, and the baffle 52 is installed on the second side wall 513 of the box body to compress the elastic locking ring 31. The cable can pass through the elastic locking ring 31 and be fixed on the box. Since the elastic locking ring 31 is elastic, the cable can be firmly fixed on the box by reducing the distance between the first locking member 10 and the second locking member 20, and the outer skin of the cable can be protected from being cut. In addition, since the elastic locking ring 31 is designed to be nested in layers, cables with different cross-sectional sizes can be accommodated by increasing or decreasing the number of elastic locking rings 31, thereby realizing that the cable fixing device of the present application can fix cables with different large cross-sectional sizes.

[0065] The present application can realize the fixation of cables of different large cross-sectional sizes, and has the advantages of simple structure, easy processing, convenient installation, high flexibility, strong holding force, high reliability, high production efficiency, and resource saving.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
