[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1 The embodiment of the present invention provides a cable bracket, which includes a bracket body 2, and a cable groove 1 is provided on the bracket body 2, which penetrates one side of the bracket body 2; so that the cable groove 1 is through-shaped on the side of the bracket body 2, and the side of the bracket body 2 is a cable inlet. The two side groove walls of the cable groove 1 are connected to the groove bottom at the opening respectively; that is, the first clamp arm 11 is arranged toward the groove bottom of the cable groove 1. The spacing between the two first clamp arms 11 gradually decreases from the opening of the cable groove 1 to the groove bottom; that is, the first clamp arm 11 is inclined toward the middle, so that the two first clamp arms 11 are in an inverted "eight" shape as a whole, and the two first clamp arms 11 form a space that decreases from top to bottom. The two first clamp arms 11 form a first claw structure as a whole, which is used to facilitate the insertion of the cable and the cable is not easy to pass out. A fixing groove 13 for matching with the cable is provided on the groove bottom of the cable groove 1. The fixing groove 13 is connected with the cable groove 1. The size of the fixing groove 13 matches the cable, so that the cable can be placed in the fixing groove 13 to form a cable fixing position.

[0026] A cable bracket provided in this embodiment, by setting a first clamping arm 11, makes it easy for the cable to be placed in the cable groove 1 and the cable is not easy to pass through the cable groove 1, thereby achieving an anti-falling effect; and a fixing groove 13 is set to fix and limit the cable, which can reduce the deviation and movement of the cable to a certain extent, which is conducive to better achieving the anti-falling effect.

[0027] Furthermore, the minimum distance between the two first clamp arms 11 should be smaller than the outer diameter of the cable. The first clamp arm 11 has an elastic deformation amount, which facilitates the smooth insertion of the cable into the cable slot 1. The bracket body 2 and the first clamp arm 11 can be plastic parts.

[0028] On the basis of the above embodiment, further, a guide groove 14 having a size larger than the size of the cable is formed between at least one first clamp arm 11 and the groove wall on the corresponding side of the cable groove 1. That is, the cable can be placed in the space formed by the first clamp arm 11 and the groove wall on the corresponding side. The groove wall on the corresponding side is the groove wall of the cable groove 1 on one side connected to the first clamp arm 11.

[0029] refer to Figure 2 This arrangement makes it possible for the cable to preferentially enter the guide groove 14 when it pops out of the fixing groove 13 due to factors such as elasticity, deformation or vibration, because the distance between the two first clamping arms 11 is small, and the space between at least one first clamping arm 11 and the corresponding side groove wall is relatively large. Because the upper part of the guide groove 14 is closed, it is more difficult for the cable to escape from the cable groove 1, thereby achieving a better anti-falling effect.

[0030] On the basis of the above embodiment, further, the bottoms of the two first clamp arms 11 are respectively connected to the second clamp arms 12, and the bottoms of the second clamp arms 12 are inclined toward the groove wall on the corresponding side of the cable groove 1. That is, the two second clamp arms 12 are arranged downwardly and back to back, and the distance between the two second clamp arms 12 gradually increases from top to bottom; the two second clamp arms 12 are in an "eight-shaped" shape as a whole, forming a second clamping claw structure. The setting of the second clamp arm 12 can limit the size of the entrance of the guide groove 14. When the cable enters the guide groove 14, the second clamp arm 12 can prevent the cable from escaping from the guide groove 14, so that the cable is not easy to escaping from the guide groove 14, and it is even more difficult to fall off from the cable bracket, thereby improving the anti-falling effect.

[0031] On the basis of the above embodiment, further, the bottom of the second clamp arm 12 is the end of the second clamp arm 12 facing the bottom of the cable trough 1. The bottom of the second clamp arm 12 and the groove wall on the corresponding side of the cable trough 1 form the entrance of the guide groove 14. The distance between the bottoms of the two first clamp arms 11 is the shortest distance between the two first clamp arms 11, which is the entrance of the entire cable support. The minimum distance between the bottom of the second clamp arm 12 and the groove wall on the corresponding side of the cable trough 1 is set to be greater than the distance between the bottoms of the two first clamp arms 11 and less than the outer diameter of the cable.

[0032] First, the entrance size of the guide groove 14 and the overall entrance size of the cable groove 1 are both smaller than the outer diameter of the cable, that is, the cable is not easy to fall off when it enters the guide groove 14 or does not enter the guide groove 14; secondly, the entrance size of the guide groove 14 is larger than the overall entrance size of the cable groove 1, so that when the cable detaches from the fixed groove 13 under the condition of vibration, it will preferentially enter the guide groove 14 instead of detaching from the cable groove 1, thereby ensuring the anti-detachment effect.

[0033] Here, the groove wall on the corresponding side refers to the groove wall connected to the second clamp arm 12. That is, the entrance size of the guide groove 14 is larger than the entrance size of the entire cable groove 1 and smaller than the outer diameter of the cable. Further, the minimum distance between the bottom of the second clamp arm 12 and the groove wall on the corresponding side of the cable groove 1 is the horizontal spacing between the bottom of the second clamp arm 12 and the groove wall on the corresponding side of the cable groove 1.

[0034] Furthermore, the vertical distance between the bottom of the second clamp arm 12 and the bottom of the cable trough 1 is set to be greater than the outer diameter of the cable. In this way, when the cable is separated from the fixing groove 13, it is easier to move to both sides, and then overcome the elastic force of the second clamp arm 12 under the action of elastic force or inertial force, and enter the guide groove 14. The bottom of the cable trough 1 is the upper surface of the fixing groove 13.

[0035] On the basis of the above embodiment, further, the groove walls on both sides of the cable groove 1 are inclined, and the distance between the groove walls on both sides gradually decreases from the opening of the cable groove 1 to the groove bottom. That is, the groove walls on both sides of the cable groove 1 are inclined outwardly from the groove bottom. The guide groove 14 is inclined, which can facilitate the cable to enter the guide groove 14, better guide the cable into a space that is less likely to fall off, and ensure the anti-falling effect.

[0036] On the basis of the above embodiment, further, the connection between the first clamp arm 11 and the groove wall of the cable groove 1 and the connection between the groove wall of the fixed groove 13 and the groove bottom of the cable groove 1 are respectively set as rounded structures. Specifically, the inner side of the connection between the first clamp arm 11 and the groove wall of the cable groove 1 is a rounded structure. That is, the top of the guide groove 14 is arc-shaped and smooth; it is beneficial to improve the stability of the cable in the guide groove 14. The connection between the groove wall of the fixed groove 13 and the groove bottom of the cable groove 1 is the opening of the fixed groove 13. This connection is set as a rounded structure, which can facilitate the cable to enter the guide groove 14 and avoid damage to the cable during the movement of the cable.

[0037] Furthermore, the outer side of the connection between the first clamp arm 11 and the groove wall of the cable groove 1, the connection between the first clamp arm 11 and the second clamp arm 12, and the connection between the groove wall and the groove bottom of the cable groove 1 can be respectively set as rounded structures, which can improve the smoothness of the cable moving path and avoid damage to the cable.

[0038] On the basis of the above embodiments, further, referring to Figure 3, this embodiment provides a magnetic ring fixing device, the magnetic ring fixing device includes the cable bracket described in any of the above embodiments, the magnetic ring fixing device also includes a magnetic ring groove 3 for matching with the magnetic ring, and the bracket body 2 of the cable bracket is arranged at one end of the magnetic ring groove 3. The magnetic ring groove 3 is used to place and fix the magnetic ring. The shape and size of the magnetic ring groove 3 match the corresponding magnetic ring, and are used to achieve good fixation of the magnetic ring and prevent it from moving. In this embodiment, the cable bracket provided by the above embodiment is applied to the magnetic ring fixing device, and the cable bracket is arranged at one end of the magnetic ring groove 3 to fix the magnetic ring outlet, which can better prevent the magnetic ring outlet from falling off.

[0039] On the basis of the above embodiment, further, an opening 6 is provided on the bottom of the magnetic ring groove 3. Because the surface of the magnetic ring is generally not a plane, but mostly an arc surface. The opening 6 is provided on the bottom of the magnetic ring groove 3 so that the outer surface of the magnetic ring can partially extend out of the opening 6, which can not only achieve better fixation of the magnetic ring, but also avoid the gap between the surface of the magnetic ring and the bottom of the groove when there is no opening 6 at the bottom of the groove, which is conducive to saving space.

[0040] refer to Figure 5 The inner wall of the magnetic ring groove 3 is connected with a limiting structure 5 for limiting and fixing the magnetic ring. The limiting structure 5 can be a limiting rib, a limiting bump, etc., which is used to abut against the surface of the magnetic ring to fix the magnetic ring. Specifically, the specific location and number of the limiting structure 5 on the inner wall of the magnetic ring groove 3 are not limited in order to achieve good fixation of the magnetic ring.

[0041] Furthermore, the inner shapes of the bottoms of the groove walls on both sides of the magnetic ring groove 3 match the magnetic ring and can be arc-shaped respectively, thereby better fixing the magnetic ring.

[0042] On the basis of the above embodiments, further, referring to Figure 4 An L-shaped wire inlet groove 4 is provided on the end surface of the magnetic ring groove 3 opposite to the bracket body 2. The L-shaped wire inlet groove 4 includes a vertical section and a horizontal section that are connected, wherein the vertical section passes through the top of the end surface of the magnetic ring groove 3 opposite to the bracket body 2. Thus, the magnetic ring wire can enter from the vertical section, and then enter the horizontal section for fixing and preventing it from falling off. Preferably, the width of the vertical section gradually decreases from top to bottom. That is, the opening of the vertical section is wider, which can facilitate the smooth entry of the magnetic ring wire.

[0043] On the basis of the above embodiment, further, multiple magnetic ring grooves 3 are connected side by side, and the sizes of multiple magnetic ring grooves 3 are the same or different. Because there is generally more than one magnetic ring in the electrical box, a corresponding number of magnetic ring grooves 3 can be set according to actual needs, and the magnetic ring grooves 3 correspond to the magnetic rings one by one and match accordingly. Further, the lengths of multiple magnetic ring grooves 3 can be the same, and the widths can be the same or different. The length of the magnetic ring groove 3 is the distance between the end face of the cable bracket and the end face of the L-shaped inlet groove 4; the width is the distance between the two groove walls. The lengths of multiple magnetic ring grooves 3 are set to be the same, and magnetic rings of different sizes are matched by different widths, so that magnetic rings of different sizes can be adapted, and multiple magnetic ring grooves 3 are arranged in order, and the incoming and outgoing lines are neat and not easy to be confused. Further, multiple magnetic ring grooves 3 can be connected side by side on the mounting plate, so that the magnetic rings are arranged in order; and can be fixed at the required position by the mounting plate.

[0044] On the basis of the above embodiments, further, this embodiment provides an air-conditioning outdoor unit, which includes the magnetic ring fixing device described in any of the above embodiments, and also includes an electrical box, and the magnetic ring fixing device is connected to the electrical box.

[0045] Further, refer to Figure 4 The mounting plate of the magnetic ring can be used as the side wall of the electrical box and can be formed integrally with the electrical box. The specific installation position and application environment of the magnetic ring groove 3 are not limited, and can be used in any environment where a magnetic ring is required, not limited to electrical boxes and air conditioners.

[0046] On the basis of the above embodiments, this embodiment further provides a magnetic ring fixing device to solve the problem that the magnetic ring wire harness is easy to fall out of the claw when the magnetic ring of the air conditioner outdoor unit computer board is fixed. The existing computer board with magnetic ring has too thick and too hard magnetic ring outlet wire, which causes the wire to fall out of the buckle easily. The general buckle is designed in the form of a hook to prevent the wire from falling off, but the hook also makes the wire difficult to install. This embodiment uses the structural design of the "eight" symmetrical claws and the additional guide groove 14 to achieve easy installation and difficult removal of the wire.

[0047] The magnetic ring fixing device mainly includes a magnetic ring groove 3 and a cable bracket arranged on one end surface of the magnetic ring groove 3. A wire inlet groove is arranged at the entrance end surface of the magnetic ring groove 3. The wire inlet groove is L-shaped, and the groove is in an inverted "eight" shape to facilitate the wire to slide in. The state of the wire after sliding in is as follows Figure 5 As shown. The cable holder provided in this embodiment is designed with symmetrical "eight" shaped claws, additional guide slots 14 and fixing slots 13, so that the wires can be easily installed and not easily removed. The two claws are symmetrically arranged to form an opening that gradually decreases from top to bottom. When it is slightly smaller than the diameter of the wire (for example, 1-1.5mm smaller), it gradually expands. In this way, when the wire is inserted, it is inserted to the smallest opening and the claws are squeezed open by the elasticity of the claws to fall into the fixing slot 13. Figure 2The claw of the right magnetic ring groove 3. When the wire pops out from the fixed groove 13 due to elasticity, deformation, vibration and other factors, it will enter the guide groove 14 along the edge of the guide groove 14. The upper end of the guide groove 14 is closed, so that the wire will not be ejected. Figure 2 The card slot of the left magnetic ring slot 3.

[0048] The cable bracket has a symmetrical figure-eight claw structure (i.e., a first claw structure and a second claw structure formed by a first arm 11 and a second arm 12); a cable groove 1 structure composed of a fixing groove 13, a guide groove 14, and a symmetrical figure-eight claw; in addition, the entrance of the magnetic ring groove 3 adopts an L-shaped wire inlet groove, and the outlet adopts a magnetic ring fixing device designed for the cable groove 1 as described above, which can better achieve an anti-falling effect.

[0049] Furthermore, the present embodiment provides an electrical box body, which can be provided with corresponding magnetic ring grooves 3 according to the number of magnetic rings of the computer board. The present embodiment enables the electrical box body to fix the wires easily and not easily fall off, thus effectively avoiding line faults caused by the wires falling out of the claws.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
