However, in scenarios where installation space is limited, it is difficult to constrain the two parts of the split-type connector at the same time, resulting in difficulty in locking the two parts and low assembly efficiency.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] According to the first aspect of this application, referring to Figures 1 to 3 This application provides a cable fixing device 100, configured to fix a cable to a device housing 210. The cable fixing device 100 includes a first connector 110, a second connector 120, and a mounting component 130. It should be understood that the device housing 210 mentioned in this embodiment is not limited to the housing of a machine casing. For example, it can also be the wall of a box, the wall of a cabinet, or the wall of a frame. As long as it is the housing of the device, it is acceptable.

[0022] The first connector 110 has an internal channel 111 for accommodating the cable, which can guide and constrain the cable; the second connector 120 is coupled to the first connector 110 so that the first connector 110 and the second connector 120 are integrally connected to the equipment housing 210, thereby fixing the cable to the equipment housing 210; the mounting member 130 is configured to be fixedly connected to the equipment housing 210.

[0023] Mounting member 130 includes a limiting structure P. The limiting structure P cooperates with the second connecting member 120 to stop the second connecting member 120 from moving relative to the mounting member 130.

[0024] It should be noted that during the engagement of the first connecting member 110 and the second connecting member 120, under the action of the first connecting member 110, the second connecting member 120 may rotate with the first connecting member 110 or move under the push of the first connecting member 110. The stop engagement in this embodiment can be understood as follows: the limiting structure P acts as a stop for the second connecting member 120 in at least one direction of rotation and movement. More specifically, the limiting structure P can abut against the second connecting member 120 to completely limit the second connecting member 120; or, a predetermined gap can be provided between the limiting structure P and the second connecting member 120 to restrict the rotation and movement of the second connecting member 120 within a certain range of motion, thereby ensuring that the first connecting member 110 and the second connecting member 120 can be smoothly engaged.

[0025] By adopting the above solution, the mounting part 130, which can be connected to the equipment housing 210, is fixed relative to the equipment housing 210. The mounting part 130 is provided with a limiting structure P, which forms a stop with the second connecting part 120 to prevent the second connecting part 120 from moving relative to the mounting part 130, thereby effectively constraining the second connecting part 120. In this way, operating the first connecting part 110 can lock the first connecting part 110 and the second connecting part 120, improving the assembly efficiency in installation space-constrained scenarios.

[0026] In some specific implementations, the first connector 110 and the second connector 120 can be connected by screws or snaps, which can be selected according to application requirements and is not limited here.

[0027] In one example of this application, the first connector 110 and the second connector 120 have compatible threaded structures. When assembled with the device housing 210, the two are screwed together to fix the first connector 110 to the device housing 210.

[0028] It should be noted that the first connector 110 and the second connector 120 can also achieve cable fastening and sealing. Fastening can be understood as locking the cable to prevent axial displacement and radial rotation, while sealing can be understood as dustproof and waterproof performance. The specific structures for fastening and sealing can be selected according to design and application requirements, and will not be elaborated here. In one example of this application, the first connector 110 and the second connector 120 together constitute a waterproof connector (i.e., a gland head), wherein the first connector 110 can be the gland head body, and the second connector 120 can be a nut.

[0029] In some embodiments of this application, the mounting component 130 may be made of metal materials such as aluminum or copper, or it may be made of insulating materials such as epoxy resin.

[0030] In some embodiments of this application, the mounting component 130 can be installed to the device housing 210 by fasteners (screws, bolts, etc.), or the mounting component 130 can be fixed to the device housing 210 by a snap-fit ​​method (e.g., a snap-fit). The choice can be made according to design and application requirements, and is not limited here.

[0031] In some embodiments of this application, reference is made to Figures 4 to 6 The outer periphery of the second connector 120 has a slit edge 121. The limiting structure P includes a first limiting portion 131. At least a portion of the first limiting portion 131 is disposed on the rotation path of the slit edge 121 to limit the rotation of the second connector 120 relative to the mounting member 130.

[0032] Understandable, refer to Figure 7 The cut edge 121 constitutes at least a portion of the peripheral sidewall of the second connector 120. The vertical distance between at least a portion of the cut edge 121 and the central axis C of the second connector 120 is less than the maximum radial dimension Rm of the second connector 120. The maximum radial dimension Rm can be the maximum value of the vertical distance between the peripheral sidewall of the second connector 120 and the central axis C, such as the radius.

[0033] It should be noted that on the projection plane perpendicular to the central axis C, the projection of the central axis C is O, and the projection of any target position point in space on the projection plane is M. The perpendicular distance between the target position point and the central axis C can be the length of the line connecting point O and point M. Specifically, the perpendicular distance between the target position point on the second connecting member 120 (e.g., the cut edge or peripheral sidewall) and the central axis C, and the perpendicular distance between the target position point on the first limiting part 131 and the central axis C can both be determined using the above method.

[0034] The rotation path of the tangent 121 can be understood as the spatial positions that the tangent 121 can rotate around the central axis C when the limiting structure P is removed. The first limiting part 131 is arranged in these spatial positions to prevent the second connector 120 from rotating around the central axis C.

[0035] By adopting the above solution, the first limiting part 131 and the cutting edge 121 can restrict the rotation of the second connecting part 120 relative to the mounting part 130, thereby preventing the second connecting part 120 from rotating. This allows for the rapid locking of the first connecting part 110 and the second connecting part 120, improving installation efficiency.

[0036] In one example of this application, the cut edge 121 can be one or a combination of two of the following: a planar structure, an arc structure, or a bent structure. The choice can be made according to design and application requirements, and is not limited here.

[0037] In one example of this application, the side of the first limiting part 131 near the cut edge 121 can also be one or a combination of two of the following: a planar structure, an arc surface structure, or a bent structure. The choice can be made according to design and application requirements and is not limited here. More specifically, the side of the first limiting part 131 near the cut edge 121 has the same shape as the cut edge 121.

[0038] In some embodiments of this application, reference is made to Figures 5 to 7 The cut edge 121 is parallel to or intersects the central axis C of the second connector 120. The first limiting part 131 is parallel to or intersects the central axis C of the second connector 120. It should be noted that the design of the cut edge 121 and the first limiting part 131 can be selected according to design and assembly requirements.

[0039] In one example of this application, reference is made to Figures 5 to 7 The cut edge 121 is parallel to the central axis C of the second connector 120, and the first limiting part 131 is parallel to the central axis C of the second connector 120, so that the first limiting part 131 and the cut edge 121 have a large contact area, thereby improving the reliability of the first limiting part 131 in limiting the cut edge 121.

[0040] In another example of this application, the cut edge 121 intersects the central axis C of the second connector 120, and the first limiting part 131 is parallel to the central axis C of the second connector 120. This can reduce the contact area between the first limiting part 131 and the cut edge 121, and reduce the resistance of the first limiting part 131 when the second connector 120 is assembled with the mounting part 130.

[0041] In another example of this application, the cut edge 121 is parallel to the central axis C of the second connector 120, and the first limiting part 131 intersects the central axis C of the second connector 120. This facilitates the cooperation between the first limiting part 131 and the cut edge 121, reduces the contact area between the first limiting part 131 and the cut edge 121, and reduces the resistance of the first limiting part 131 encountered when the second connector 120 is assembled with the mounting part 130.

[0042] In another example of this application, the cut edge 121 intersects the central axis C of the second connector 120, and the first limiting part 131 also intersects the central axis C of the second connector 120. In this example, the cut edge 121 and the corresponding first limiting part 131 can be parallel or intersecting. The contact area of ​​the first limiting part 131 with the second connector 120 can be flexibly adjusted according to different intersection angles to meet different limiting requirements.

[0043] In some embodiments of this application, reference is made to Figure 7The distance between the cut edge 121 and the central axis C is defined as L1, the distance between the first limiting part 131 and the central axis C is defined as L2, and the maximum radial dimension of the second connecting member 120 is Rm. L2 is greater than or equal to L1, and L2 is less than Rm.

[0044] It can be understood that the distance between the cutting edge 121 and the central axis C can be the shortest perpendicular distance between the cutting edge 121 and the central axis C, or it can be the average of the perpendicular distances between each point on the cutting edge 121 and the central axis C. The distance between the first limiting part 131 and the central axis C can also be determined in a similar manner.

[0045] The maximum radial dimension of the second connector 120 can be the maximum value of the vertical distance between the peripheral sidewall of the second connector 120 and the central axis C.

[0046] When L2 equals L1, the first limiting part 131 contacts and engages with the cutting edge 121. While restricting the rotation of the second connecting member 120, the first limiting part 131 can also clamp the second connecting member 120 to prevent it from being pushed and moved. When L2 is greater than L1, there is a gap between the first limiting part 131 and the cutting edge 121.

[0047] By adopting the above solution, by limiting L2 to be greater than or equal to L1, interference between the first limiting part 131 and the cutting edge 121 can be avoided, ensuring the assemblability of the first limiting part 131 and the second connecting member 120; at the same time, by limiting L2 to be less than Rm, it can be ensured that the first limiting part 131 is located on the rotation path of the cutting edge 121 around the central axis C, effectively ensuring that the first limiting part 131 provides reliable limiting for the cutting edge 121.

[0048] In some embodiments of this application, the number of first limiting portions 131 that mate with the same second connector 120 is defined as N1, and the number of cut edges 121 in the same second connector 120 is defined as N2. N1 is less than or equal to N2.

[0049] Using the above scheme, when N1 equals N2, each cut edge 121 corresponds to a first limiting part 131 that engages with it. This design ensures that each cut edge 121 is precisely limited, improving the stability and reliability of the second connector 120. When N1 is less than N2, assembly can be achieved by having a portion of the cut edges 121 engage with the first limiting part 131. This reduces the assembly accuracy requirements of the second connector 120, improves assembly efficiency, and reduces the number of first limiting parts 131, thus reducing the processing difficulty of the mounting part 130.

[0050] In one example of this application, the number of cut edges 121 in the same second connector 120 is greater than or equal to 2, and the number of first limiting portions 131 that cooperate with the same second connector 120 is greater than or equal to 1.

[0051] In some embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 9 At least two first limiting portions 131 are spaced apart along the circumference of the same second connector 120.

[0052] By adopting the above solution, and with at least two first limiting parts 131 spaced apart, the stability of the second connector 120 in the circumferential direction can be further enhanced, avoiding loosening or deformation of the connection due to uneven local stress. At the same time, the arrangement of at least two first limiting parts 131 also ensures that even if one first limiting part 131 fails to limit, the other first limiting parts 131 can still play an effective limiting role, thereby improving the reliability of the mounting part 130.

[0053] In one example of this application, at least two first limiting portions 131 are evenly spaced along the circumference of the second connector 120, thereby improving the uniformity of the resistance experienced by the second connector 120. For example, when an even number of first limiting portions 131 are provided along the circumference of the same second connector 120, the first limiting portions 131 are arranged opposite each other in the circumference (i.e., two first limiting portions 131 are arranged at a 180° interval). When an odd number (greater than one) of first limiting portions 131 are provided along the circumference of the same second connector 120, the odd number of first limiting portions 131 are evenly spaced; for example, three first limiting portions 131 are provided along the circumference of the same second connector 120, with adjacent first limiting portions 131 arranged at a 120° interval in the circumference.

[0054] In one example of this application, reference is made to Figure 5 and Figure 6 The number of cut edges 121 in the same second connector 120 is 6, and the number of first limiting parts 131 that mate with the same second connector 120 is 2. In this example, the second connector 120 can be a hexagonal nut.

[0055] In some embodiments of this application, the first limiting part 131 that cooperates with the same second connector 120 is defined as a limiting group U, and at least two limiting groups U are distributed along a preset direction X2.

[0056] It is understood that the mounting component 130 can be equipped with at least two limit groups U, thereby enabling the mounting component 130 to limit at least two second connecting components 120; the number of limit groups U can be flexibly adjusted according to the installation space and actual needs, and there is no limitation on this.

[0057] By adopting the above scheme and setting at least two limit groups U, in actual operation, it is not necessary to limit and disassemble each of the second connectors 120 individually, thereby realizing the one-time disassembly and assembly of multiple second connectors 120, which improves the efficiency of equipment installation and maintenance.

[0058] In one example of this application, at least two limit groups U are arranged at intervals along a preset direction X2, and each limit group U includes an independent first limit part 131.

[0059] In another example of this application, at least two limit groups U are arranged along a preset direction X2, and two adjacent limit groups U can share at least one first limit part 131.

[0060] In some embodiments of this application, reference is made to Figure 5 and Figure 6 The limiting structure P further includes a second limiting portion 132. In the engagement direction X1 perpendicular to the first connector 110 and the second connector 120, the second limiting portion 132 is located on the axial side of the second connector 120. On a projection plane perpendicular to the engagement direction X1, the projection of the second limiting portion 132 at least partially coincides with the projection of the second connector.

[0061] It can be understood that the engagement direction X1 of the first connector 110 and the second connector 120 can be the direction of relative movement when the first connector 110 and the second connector 120 are engaged, and the engagement direction X1 can be parallel to the axis of the second connector 120; while the second limiting part 132 limits the second connector 120 on the axis of the second connector 120.

[0062] By adopting the above solution, by limiting the second limiting part 132 to be located on the axial side of the second connector 120 and the projection relationship between the two, the second limiting part 132 can block the second connector 120, thereby restricting the movement of the second connector 120 in the engagement direction X1, and ensuring that the first connector 110 and the second connector 120 are effectively engaged.

[0063] In some embodiments of this application, reference is made to Figure 5 and Figure 6 The second limiting part 132 is arranged to intersect with the central axis C of the second connecting member 120.

[0064] It is understandable that the central axis C of the second limiting part 132 and the second connecting part 120 can be inclined to intersect or set perpendicularly.

[0065] By adopting the above scheme, the arrangement of the second limiting part 132 and the second connecting member 120 is limited, which can further enhance the limiting effect of the second limiting part 132 on the second connecting member 120, ensure that the second connecting member 120 will not deviate in the joint direction X1, and thus improve the stability and reliability of the joint between the first connecting member 110 and the second connecting member 120.

[0066] In one example of this application, reference is made to Figure 5 and Figure 6 The second limiting part 132 is set perpendicular to the central axis C of the second connecting part 120, which helps to optimize the overall structural layout and make the overall structure of the mounting part 130 and the second connecting part 120 more compact.

[0067] In some embodiments of this application, reference is made to Figure 5 and Figure 6 The first limiting part 131 is connected to the second limiting part 132, and the first limiting part 131 and the second limiting part 132 are intersecting.

[0068] It is understandable that the first limiting part 131 and the second limiting part 132 can be inclined to intersect or set perpendicularly.

[0069] By adopting the above scheme, the limiting system formed by the first limiting part 131 and the second limiting part 132 improves the structural compactness of the mounting part 130, while the first limiting part 131 can work in coordination with the second limiting part 132 to achieve a more comprehensive limiting of the second connecting part 120 by the mounting part 130.

[0070] In some embodiments of this application, reference is made to Figure 8 and Figure 9 The second limiting part 132 has a through hole 132a; the diameter D1 of the through hole 132a is smaller than the outer diameter D2 of the second connector 120.

[0071] It is understood that the through hole 132a penetrates the second limiting part 132 along the joining direction X1, and the through hole 132a is connected to the internal channel 111 of the first connector 110 so that the cable can pass through the mounting part 130.

[0072] By adopting the above solution, by limiting the diameter of the through hole 132a to be smaller than the outer diameter of the second connector 120, the first connector 110 can be blocked from passing through the through hole 132a, thereby ensuring reliable positioning of the second connector 120.

[0073] In one example of this application, the outer diameter of the second connector 120 may be twice the maximum radial dimension Rm of the second connector 120.

[0074] In some embodiments of this application, reference is made to Figure 8 and Figure 9The diameter D1 of the through hole 132a is greater than or equal to the inner diameter D3 of the internal channel 111.

[0075] By adopting the above solution, the diameter of the through hole 132a is limited to be greater than or equal to the inner diameter of the internal channel 111, so as to avoid affecting the passage of the cable at the through hole 132a.

[0076] In one example of this application, the second connector 120 has an inner hole that mates with the first connector 110, and the diameter of the through hole 132a is greater than or equal to the diameter of the inner hole.

[0077] In one example of this application, the diameter of the through hole 132a is smaller than the outer diameter of the second connector 120, and the diameter of the through hole 132a is greater than or equal to the inner diameter of the internal channel 111.

[0078] In some embodiments of this application, reference is made to Figure 6 At least two first limiting parts 131 are arranged at intervals around the same through hole 132a.

[0079] By adopting the above solution, by limiting the positional relationship between the first limiting part 131 and the through hole 132a, the first limiting part 131 can not only block the rotation of the second limiting member, but also make the second connecting member 120 aligned with the through hole 132a, thus ensuring the reliable limiting of the second connecting member 120 by the second limiting part 132.

[0080] In some specific embodiments, based on the second limiting part 132 forming a through hole 132a, the first limiting part 131 can be formed by partially bending the second limiting part 132; this design makes the connection between the first limiting part 131 and the second limiting part 132 more stable and can effectively save material costs. At the same time, this structural form is also easy to process and manufacture, improving production efficiency.

[0081] In one example of this application, reference is made to Figure 6 and Figure 9 The second limiting portion 132 also has a bending space 132b. The bending space 132b is located at the edge of the through hole 132a and communicates with the through hole 132a; the first limiting portion 131 is located on the side of the bending space 132b away from the through hole 132a. It can be understood that the size of the bending space 132b is similar to the size of the first limiting portion 131, and the second limiting portion 132 is located in the bending space 132b before the first limiting portion 131 bends to intersect with the second limiting portion 132.

[0082] In some embodiments of this application, reference is made to Figure 5 , Figure 6 and Figure 9At least two through holes 132a are spaced apart along a preset direction X2, and the first limiting part 131 is inclined relative to the preset direction X2.

[0083] It is understood that the preset direction X2 intersects with the coupling direction X1, and at least two through holes 132a are provided through the second limiting part 132 so that the same mounting part 130 can simultaneously adapt to the limiting of at least two second connecting parts 120.

[0084] By adopting the above scheme, based on setting at least two through holes 132a, the first limiting part 131 is tilted relative to the preset direction X2. While ensuring the structural strength of the second limiting part 132, the two adjacent through holes 132a can be set to a smaller distance, thereby reducing the size of the mounting part 130 in the preset direction X2.

[0085] In one example of this application, two first limiting portions 131 are spaced apart around the same through hole 132a, and the first limiting portions 131 on the same mounting member 130 are parallel to each other.

[0086] In some specific implementation methods, refer to Figure 9 The angle α between the first limiting part 131 and the preset direction X2 ranges from 48° to 72°.

[0087] In one example of this application, two first limiting parts 131 are arranged at intervals around the through hole 132a, and the angle α between the first limiting part 131 and the preset direction X2 is in the range of 60°.

[0088] In some embodiments of this application, reference is made to Figure 6 and Figure 10 Mounting component 130 has: mounting surface 133.

[0089] Mounting surface 133 is configured to contact the device housing 210; in the engagement direction X1 of the first connector 110 and the second connector 120, the distance H1 between the second limiting part 132 and the mounting surface 133 is greater than or equal to the thickness H2 of the second connector 120.

[0090] It is understood that the mounting component 130 contacts the equipment housing 210 through the mounting surface 133, thereby improving the stability of the connection between the mounting component 130 and the equipment housing 210.

[0091] By adopting the above solution, by limiting the distance between the second limiting part 132 and the mounting surface 133 to be greater than or equal to the thickness of the second connector 120, this design ensures that the second connector 120 can be accommodated between the second limiting part 132 and the mounting surface 133, and avoids the second connector 120 protruding from the mounting surface 133 and affecting the assembly of the mounting part 130 and the equipment housing 210.

[0092] According to the second aspect of this application, referring to Figure 3 and Figure 13 An electrical device 10 is provided, which includes a housing 210 and a cable fixing device 100 as described above; the cable fixing device 100 is mounted on the housing 210. The electrical device 10 has all the beneficial effects of the cable fixing device 100 described above, which will not be repeated here.

[0093] It should be noted that the cable fixing device 100 in this application embodiment can be applied to all scenarios where cables need to be introduced into the equipment housing 210. For example, the electrical equipment 10 can be equipment in the new energy field such as inverters, combiner boxes, energy storage cabinets, and charging piles; municipal building equipment such as junction boxes for outdoor lighting, traffic lights, surveillance cameras, building exterior wall sensors, and outdoor low-voltage boxes; marine equipment such as ship engine room equipment, deck lighting, and underwater detection equipment; or industrial equipment such as valve control boxes, explosion-proof instruments, ventilation equipment, PLC control cabinets, servo motors, and sensors. This application does not specifically limit it in this regard.

[0094] In some embodiments of this application, the mounting member 130 is fixed to the device housing 210, and at least a portion of the first connector 110 passes through the device housing 210.

[0095] It is understood that at least a portion of the first connector 110 passes through the device housing 210 so that the cable passes through the device housing 210; after the first connector 110 and the second connector 120 are combined, the first connector 110 and the second connector 120 are locked together with the device housing 210, thereby fixing the cable on the device housing 210.

[0096] By adopting the above solution, by fixing the mounting part 130 connected to the stop of the second connector 120 to the equipment housing 210, for example, by fixing the mounting part 130 connected to the stop of the second connector 120 to the inner wall of the equipment housing 210, the mounting part 130 and the second connector 120 can adapt to the limited space inside the equipment housing 210. The second connector 120 can be fixed without manual assistance. The connection between the first connector 110 and the second connector 120 can be achieved by operating the first connector 110. The operation is simple and the assembly efficiency is improved.

[0097] This application exemplarily describes at least a portion of the assembly process of electrical equipment 10: Refer to Figure 11 The second connector 120 is placed between at least two first limiting portions 131, such that the cut edge 121 of the second connector 120 mates with the first limiting portions 131; refer to Figure 12 The mounting piece 130, on which the second connector 120 is installed, is fixed to the equipment housing 210 using fasteners (bolts, screws, etc.); refer to Figure 13 The first connector 110 is passed through the equipment housing 210 and locked with the second connector 120, thus completing the installation of the first connector 110 and the second connector 120 on the equipment housing 210.
