Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to an anti-slip structure for connecting wires and an electrical appliance. Background Technology

[0002] In existing technology, the indoor display panel box uses a single clip on the upper and lower covers to secure the leads extending from the circuit board. On one hand, the tightness of the clip is difficult to control precisely. If it's too tight, it will excessively compress the wires, causing wear and cracking of the wire sheath, and even breaking of the internal wire core, directly affecting circuit conductivity, shortening the lead's lifespan, and increasing maintenance and replacement costs. If it's too loose, the lead loses effective restraint, causing the connection point between the lead and the circuit board to loosen or detach, leading to poor contact, signal interruption, and other malfunctions. On the other hand, this single-clip design cannot form a tight seal; gaps exist between the upper and lower covers and the leads, allowing external dust, moisture, and other impurities to easily enter the display panel box. Utility Model Content

[0003] Therefore, it is necessary to provide a structure and electrical component that prevents the connection wires from sliding, addressing the issue of using a single fastener to fix the circuit board leads in the indoor unit display board box.

[0004] A structure for preventing connector slippage, characterized in that the structure comprises: a housing assembly having a receiving cavity; a first fixing component disposed on the housing assembly and located within the receiving cavity, the first fixing component having a first fixing space; a second fixing component disposed on the housing assembly and located at one end of the housing assembly, the second fixing component being adjacent to the first fixing component, the second fixing component having a second fixing space; and a circuit board assembly, a portion of which is disposed on the housing assembly and located within the receiving cavity, the remaining portion of which sequentially passes through the first fixing space and the second fixing space and abuts against the first fixing component and the second fixing component.

[0005] The above-disclosed structure provides an anti-slip structure for the connecting wire. Firstly, this structure effectively solves the problem of insecure wire fixation. Existing structures rely solely on a single clip, making it difficult to control the tightness. Excessive tightness can damage the wire, while insufficient tightness leads to slippage and increases the risk of damage. This structure employs a double-layer clamp design formed by a first and second fixing component. The first and second fixing spaces provide dual restraint for the wire, ensuring stable clamping. Simultaneously, the wire naturally deforms in a wave-like shape under the action of the first and second fixing spaces. The resulting reverse force further enhances the fixing effect, significantly reducing the possibility of wire slippage and ensuring connection stability. Secondly, this structure improves the lifespan of the wire. Existing single clips, due to improper tightness, can easily cause wear on the wire sheath or breakage of the internal core. The first and second fixing spaces of this structure, through reasonable spatial design, ensure fixing strength while avoiding excessive compression of the wire, reducing wire damage and extending the wire's service life. Thirdly, this structure enhances dust and water resistance. Existing structures rely solely on upper and lower cover clamping and a single snap-fit, which is insufficient to create a tight seal. This allows dust and moisture to easily damage the circuit board assembly, affecting normal circuit operation. In this structure, the circuit board assembly abuts against the first and second fixing components, and the double-layered snap-fit ​​space tightly wraps the leads, forming a double-sealed barrier at the lead exit points. This effectively prevents dust and moisture from intruding, providing more reliable protection for the internal circuit board assembly.

[0006] In one embodiment, the first fixing component includes a first upper fixing member, a first lower fixing member, and protrusions. The first upper fixing member and the first lower fixing member are both disposed on the housing assembly and located on two opposite sides of the housing assembly. Multiple protrusions are spaced apart on the first upper fixing member, and the remaining multiple protrusions are spaced apart on the first lower fixing member. The relative arrangement of the first upper and first lower fixing members forms a stable first fixing space foundation structure, providing a vertical clamping foundation for the leads. This vertically aligned layout can initially limit the passing leads from both sides, preventing significant deviation of the leads in a single direction. Secondly, the multiple spaced protrusions are key to enhancing the fixing effect. When the leads of the circuit board assembly pass through the first fixing space, the protrusions exert multi-point pressure on the leads. This design avoids excessive pressure that may result from a single clamping action and increases the friction between the leads and the fixing component through dispersed contact points, further limiting the sliding tendency of the leads. Meanwhile, the spacing of the bumps can guide the leads of the circuit board assembly to form local deformation within the first fixed space. When combined with the second fixed component, it can enhance the overall wavy bending effect of the leads and enhance the anti-slip ability by utilizing the stress generated by the deformation.

[0007] In one embodiment, the first upper fixing member and the first lower fixing member are disposed opposite to each other, with the center surfaces of the first upper fixing member and the first lower fixing member coinciding. The first upper fixing member and the first lower fixing member cooperate to form the first fixing space. A portion of the circuit board assembly passes through the first fixing space and abuts against the plurality of protrusions. The first upper fixing member and the first lower fixing member are disposed adjacent to the second fixing component. By disposing the first upper fixing member and the first lower fixing member opposite to each other with their center surfaces coinciding, the first fixing space is ensured to have a symmetrical structure in the vertical direction. This symmetrical layout allows the leads of the circuit board assembly passing through to be subjected to uniform clamping force, avoiding localized excessive compression or loosening of the fixing due to force offset, thus enhancing the reliability of the fixing and reducing asymmetrical damage to the leads. When the circuit board assembly passes through the first fixing space, it abuts against the plurality of protrusions on the upper and lower fixing members. The symmetrically distributed fixing members ensure that the protrusions can form a balanced multi-point compression on the leads from both the upper and lower sides. This design causes the lead wire to undergo regular localized deformation within the first fixed space, forming a stable frictional contact with the protrusion, further limiting the axial sliding of the lead wire. Simultaneously, it lays the foundation for subsequent overall wave-shaped deformation in conjunction with the second fixed component. The first upper and lower fixing components are arranged adjacent to the second fixed component, shortening the distance between the two fixed spaces and allowing the lead wire to pass through two consecutive limiting points within a short distance. This compact layout enhances the synergistic effect of the two fixed spaces, ensuring the stability of the wave-shaped deformation formed by the lead wire and preventing deformation recovery or increased sliding space due to excessive spacing, thereby improving the overall anti-slip effect.

[0008] In one embodiment, the second fixing component includes a second upper fixing member, a second lower fixing member, and transition members. The second upper fixing member and the second lower fixing member are both disposed on the housing assembly and located on two opposite sides of the housing assembly. Two transition members are disposed on the second upper fixing member and the second lower fixing member and located on the side away from the receiving cavity. The relative arrangement of the second upper fixing member and the second lower fixing member forms an upper and lower clamping structure corresponding to the first fixing component, providing a stable frame foundation for the second fixing space. This upper and lower distribution method, consistent with the first fixing component, ensures that the force direction is consistent when the lead wire passes through the two fixing spaces continuously, facilitating the formation of regular wave-shaped deformation and enhancing the overall anti-slip effect. Furthermore, the transition members adopt a rounded corner design. The rounded corner structure avoids the hard compression of the lead wires of the circuit board assembly by right angles or sharp edges, allowing the wire to maintain moderate deformation rather than excessive deformation. It also disperses stress through a smooth curved surface when the lead wire is pulled or swayed, preventing the wire insulation from being cut or worn.

[0009] In one embodiment, the second upper fixing member and the second lower fixing member are arranged opposite to each other, with the center surfaces of the second upper fixing member and the second lower fixing member coinciding. The first upper fixing member and the first lower fixing member cooperate to form the second fixing space. A portion of the circuit board assembly passes through the second fixing space and abuts against the second upper fixing member and the second lower fixing member. The second upper fixing member and the second lower fixing member are arranged adjacent to the first fixing component. By arranging the second upper fixing member and the second lower fixing member opposite to each other with their center surfaces coinciding, the formed second fixing space presents a symmetrical structure. This symmetrical layout allows the leads of the circuit board assembly passing through to receive a balanced clamping force, avoiding wire displacement or local damage caused by excessive force on one side. This ensures the reliability of the fixing and reduces asymmetrical pressure on the wires. When the circuit board assembly passes through the second fixing space, it directly abuts against the second upper fixing member and the second lower fixing member. Combined with the protrusion limiting of the first fixing component, a continuous double constraint is formed. Because the two fixed components are set up adjacent to each other, the lead wire will naturally form a regular wave-shaped deformation as it passes through two symmetrical fixed spaces in a short distance. The reverse stress generated by this deformation can effectively resist the sliding tendency of the lead wire and greatly improve the anti-slip effect.

[0010] In one embodiment, the cross-sectional area of ​​the first fixing space is smaller than that of the second fixing space. This is achieved by designing the cross-sectional area of ​​the first fixing space to be smaller than that of the second fixing space, with the long side of the first fixing space being slightly smaller than the diameter of the second fixing space by 0.5 mm. When the leads of the circuit board assembly pass sequentially through the smaller first fixing space and the slightly larger second fixing space, a controllable bending curvature naturally occurs due to the stepped change in space dimensions. The tight clamping of the first fixing space causes the leads to undergo inward contraction deformation at this point, while the moderately loose second fixing space provides space for the leads to extend outward. Together, they form a stable contraction-extension wave structure. This deformation generates a uniform stress distribution, which both prevents axial sliding of the leads through structural tension and avoids damage to the wires caused by excessive bending.

[0011] In one embodiment, the central axis of the first fixed space coincides with the central axis of the second fixed space. By designing the central axis of the first fixed space to coincide with the central axis of the second fixed space, the leads of the circuit board assembly remain on the same axis as they pass through the two fixed spaces sequentially, and the clamping force in the vertical direction can be evenly applied to both sides of the wire. This coaxial layout can prevent excessive friction between the leads and the fixed components on one side due to misalignment, reduce the risk of breakage caused by local wear of the wire sheath or uneven stress on the internal wire core, and extend the service life of the leads. Secondly, the coincidence of the central axes ensures that the positions of the two fixed spaces are precisely corresponding. When the leads enter the slightly larger second fixed space from the first fixed space with a smaller cross-sectional area, a symmetrical and controllable wavy bending shape can be formed.

[0012] In one embodiment, the first fixing space is elliptical in shape, with its major axis parallel to the horizontal plane and its minor axis perpendicular to the horizontal plane. By designing the first fixing space as an ellipse and setting the minor axis along the vertical direction, a moderate vertical clamping force can be formed on the lead wire, ensuring a solid foundation. The major axis extending horizontally avoids damage to the lead wire caused by excessive compression and provides lateral buffer space for the lead wire, accommodating minor deformations caused by slight shaking or temperature changes. When the first fixing space engages with the protrusion, it allows the protrusion to contact the lead wire surface more evenly from both the top and bottom, forming a multi-point clamping effect. This contact method increases friction to prevent slippage and disperses pressure to prevent excessive local pressure on the lead wire.

[0013] In one embodiment, the circuit board assembly includes a circuit board and leads. The circuit board is disposed on the housing assembly and located within the receiving cavity. One end of the lead is disposed on the circuit board, and the lead sequentially passes through the first fixed space and the second fixed space, abutting against the first and second fixed components. By fixing the circuit board leads within the receiving cavity, they serve as carriers for core circuit components, undertaking signal processing and functional control tasks. One end of the lead is connected to the circuit board leads, and the other end extends to the outside through the first and second fixed spaces, forming a physical connection channel between the internal and external circuits. This structure ensures the circuit continuity required for electrical functions and, through the cooperation of the leads and the fixed components, constrains the circuitry to a preset trajectory, avoiding poor circuit contact or functional failure due to loose leads. The leads sequentially pass through the first and second fixed spaces and tightly abut against the two fixed components, causing the wires to form a controllable wave-like deformation under dual constraints. The first fixing component forms an initial clamping by pressing the protrusions and the lead wire at multiple points, while the second fixing component achieves secondary positioning through symmetrical space. The two components work together to generate a synergistic force by utilizing the deformation of the lead wire, continuously resisting the tendency of the lead wire to slide.

[0014] In one embodiment, the housing assembly includes a main housing and an extension housing, the extension housing being disposed on the main housing, the first fixing component and the second fixing component being disposed on the extension housing, and a portion of the circuit board assembly being disposed on the main housing, the main housing having the receiving cavity. By utilizing the receiving cavity of the main housing to provide a stable mounting space for the main body of the circuit board assembly leads, the core circuit components are ensured to be in a relatively enclosed protective environment. The extension housing leads, as a functional extension structure, not only provide a basis for integrated mounting of the first fixing component leads and the second fixing component leads, making the double-layer fixing structure an independent and centralized constraint unit, but also, through connection with the main housing leads, construct a transition channel from the internal receiving cavity to the external wiring, guiding the circuit board assembly leads to smoothly extend from the main housing leads to the fixed space of the extension housing leads, forming a continuous circuit path. This structural division not only ensures the safety protection of the internal circuitry, but also makes the installation of fixed components and the constraint of leads more targeted. At the same time, through the cooperation of the main shell and the extension shell, the sealing and mechanical stability of the overall structure are enhanced, providing a basic support for the realization of functions such as anti-slip, dustproof and waterproof.

[0015] In one embodiment, the housing assembly further includes a display space for displaying information about the circuit board assembly. By providing a display space on the housing assembly, various data generated during circuit board operation, such as status parameters and fault prompts, can be presented intuitively, allowing users to easily understand the device's operating status in real time.

[0016] The second aspect of this application discloses an electrical appliance, which includes: the aforementioned anti-slip structure for connecting wires; and an electrical appliance body, wherein the anti-slip structure for connecting wires is disposed on the electrical appliance body.

[0017] The second aspect disclosed above discloses an electrical appliance that significantly improves the overall operational reliability and service life of the appliance by setting an anti-slip structure on the appliance body. The anti-slip structure, with its double-layer fixing structure and size-adapted fixing space, can effectively prevent poor contact or wire damage caused by slippage or loosening of the leads of the circuit board assembly, and reduce electrical failures caused by wiring problems. At the same time, its enhanced dustproof and waterproof performance can provide better protection for the internal circuit of the appliance. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the anti-slip structure and electrical appliance of this utility model.

[0038] Example 1

[0039] like Figures 1 to 12 As shown, this embodiment discloses an anti-slip structure for connecting wires, including: a housing assembly 1, which has a receiving cavity 101; a first fixing component 2, which is disposed on the housing assembly 1 and located in the receiving cavity 101, and has a first fixing space 201; a second fixing component 3, which is disposed on the housing assembly 1 and located at one end of the housing assembly 1, and is adjacent to the first fixing component 2, and has a second fixing space 301; and a circuit board assembly 4, which has a portion disposed on the housing assembly 1 and located in the receiving cavity 101, and the remaining portion of the circuit board assembly 4 passes through the first fixing space 201 and the second fixing space 301 in sequence and abuts against the first fixing component 2 and the second fixing component 3.

[0040] This application discloses an anti-slip structure for connector wires. First, this structure effectively solves the problem of insecure wire fixation. Existing structures rely solely on a single clip to hold the wire, making it difficult to control the tightness. Excessive tightness can damage the wire, while insufficient tightness leads to wire slippage, increasing the risk of damage. This structure employs a double-layer clamp design formed by a first fixing component 2 and a second fixing component 3. The first fixing space 201 and the second fixing space 301 provide dual restraint for the wire, ensuring stable wire clamping. Simultaneously, the wire naturally undergoes a wave-like deformation under the action of the first fixing space 201 and the second fixing space 301. The resulting reverse force further enhances the fixing effect, significantly reducing the possibility of wire slippage and ensuring connection stability. Second, this structure improves the lifespan of the wire. Existing single clips, due to improper tightness, can easily cause wear on the wire sheath or breakage of the internal core. The first fixing space 201 and the second fixing space 301 of this structure, through reasonable spatial design, ensure both fixing strength and avoid excessive compression of the wire, reducing wire damage and extending the wire's service life. Furthermore, this structure enhances dust and water resistance. Existing structures rely solely on upper and lower cover clamping and a single snap-fit, which is insufficient to create a tight seal, allowing dust and moisture to easily damage the circuit board assembly 4 and affect normal circuit operation. In this structure, the circuit board assembly 4 abuts against the first fixing component 2 and the second fixing component 3, and the double-layered snap-fit ​​space tightly wraps the leads, forming a double sealing barrier at the lead exit point. This effectively prevents dust and moisture from intruding, providing more reliable protection for the internal circuit board assembly 4.

[0041] like Figure 1 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the first fixing component 2 includes a first upper fixing member 21, a first lower fixing member 22, and protrusions 23. The first upper fixing member 21 and the first lower fixing member 22 are both disposed on the housing component 1 and are respectively located on two opposite sides of the housing component 1. There are multiple protrusions 23, which are spaced apart on the first upper fixing member 21 and spaced apart on the other multiple protrusions 23 on the first lower fixing member 22. By the relative arrangement of the first upper fixing member 21 and the first lower fixing member 22, a stable basic structure of the first fixing space 201 is formed, providing a clamping basis for the lead wire in the vertical direction. This vertically corresponding layout can initially limit the lead wire passing through from both sides, avoiding large deviation of the lead wire in a single direction. Secondly, the multiple spaced protrusions 23 are the core of enhancing the fixing effect. When the lead wire of the circuit board component 4 passes through the first fixing space 201, the protrusions 23 will form multi-point compression on the lead wire. This design avoids excessive pressure that may result from a single clamping mechanism, and increases the friction between the lead wire and the fixing component through dispersed contact points, further limiting the lead wire's tendency to slide. At the same time, the spaced distribution of the bumps 23 can guide the lead wire of the circuit board assembly 4 to form local deformation within the first fixing space 201. When combined with the second fixing component 3, it can enhance the overall wavy bending effect of the lead wire and use the stress generated by the deformation to enhance the anti-slip ability.

[0042] like Figure 1 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first upper fixing member 21 and the first lower fixing member 22 are arranged opposite to each other, and the center plane of the first upper fixing member 21 coincides with the center plane of the first lower fixing member 22. The first upper fixing member 21 and the first lower fixing member 22 cooperate to form a first fixing space 201. A portion of the circuit board assembly 4 passes through the first fixing space 201 and abuts against multiple protrusions 23. The first upper fixing member 21 and the first lower fixing member 22 are arranged adjacent to the second fixing assembly 3. By arranging the first upper fixing member 21 and the first lower fixing member 22 opposite to each other and having their center planes coincide, the first fixing space 201 is ensured to have a symmetrical structure in the vertical direction. This symmetrical layout enables the leads of the circuit board assembly 4 to be subjected to uniform clamping force, avoiding local excessive compression or loosening of the fixation due to force offset, which not only enhances the reliability of the fixation but also reduces asymmetrical damage to the wires. When the circuit board assembly 4 passes through the first fixing space 201, it abuts against multiple protrusions 23 on the upper and lower fixing members. The symmetrically distributed fixing members ensure that the protrusions 23 can form a balanced multi-point compression on the lead wire from both the upper and lower sides. This design causes the lead wire to produce regular local deformation within the first fixing space 201, forming a stable frictional contact with the protrusions 23, further limiting the axial sliding of the lead wire, and laying the foundation for subsequent overall wave-shaped deformation in conjunction with the second fixing assembly 3. The first upper fixing member 21 and the first lower fixing member 22 are arranged adjacent to the second fixing assembly 3, shortening the distance between the two fixing spaces, allowing the lead wire to pass through the limiting position twice in a short distance. This compact layout enhances the synergistic effect of the two fixing spaces, ensuring the stability of the wave-shaped deformation formed by the lead wire, avoiding deformation recovery or increased sliding space due to excessive spacing, thereby improving the overall anti-slip effect.

[0043] like Figure 2 , Figure 8 , Figure 9 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second fixing component 3 includes a second upper fixing member 31, a second lower fixing member 32, and a transition member 33. The second upper fixing member 31 and the second lower fixing member 32 are both disposed on the outer shell component 1 and are respectively located on two opposite sides of the outer shell component 1. There are two transition members 33, which are disposed on the second upper fixing member 31 and the second lower fixing member 32 and are located on the side away from the receiving cavity 101. By the relative arrangement of the second upper fixing member 31 and the second lower fixing member 32, an upper and lower clamping structure corresponding to the first fixing component 2 is formed, providing a stable frame foundation for the second fixing space 301. This upper and lower distribution method consistent with the first fixing component 2 can ensure that the force direction is consistent when the lead wire passes through the two fixing spaces continuously, which facilitates the formation of regular wave-shaped deformation and enhances the overall anti-slip effect. Secondly, the transition piece 33 adopts a rounded corner design. The rounded corner structure avoids the hard compression of the leads of the circuit board assembly 4 by right angles or sharp edges, so that the lead body maintains moderate deformation rather than excessive deformation. It can also disperse stress through the smooth curved surface when the lead is pulled or swayed, preventing the wire sheath from being cut or worn.

[0044] like Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second upper fixing member 31 and the second lower fixing member 32 are arranged opposite to each other, and the center plane of the second upper fixing member 31 coincides with the center plane of the second lower fixing member 32. The first upper fixing member 21 and the first lower fixing member 22 cooperate to form a second fixing space 301. A portion of the circuit board assembly 4 passes through the second fixing space 301 and abuts against the second upper fixing member 31 and the second lower fixing member 32. The second upper fixing member 31 and the second lower fixing member 32 are arranged adjacent to the first fixing assembly 2. By arranging the second upper fixing member 31 and the second lower fixing member 32 opposite to each other and having their center planes coincide, the formed second fixing space 301 presents a symmetrical structure. This symmetrical layout allows the leads of the circuit board assembly 4 to receive a balanced clamping force, avoiding wire displacement or local damage caused by excessive force on one side. This ensures the reliability of the fixation and reduces asymmetrical pressure on the wires. When the circuit board assembly 4 passes through the second fixing space 301, it directly abuts against the second upper fixing member 31 and the second lower fixing member 32. Combined with the limiting position of the protrusion 23 of the first fixing assembly 2, a continuous double constraint is formed. Since the two fixing components are arranged adjacently, the lead wire will naturally form a regular wave-shaped deformation as it passes through the two symmetrical fixing spaces in a short distance. The reverse stress generated by this deformation can effectively resist the sliding tendency of the lead wire and greatly improve the anti-slip effect.

[0045] like Figure 7 , Figure 8 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the first fixed space 201 is smaller than the cross-sectional area of ​​the second fixed space 301. By designing the cross-sectional area of ​​the first fixed space 201 to be smaller than the cross-sectional area of ​​the second fixed space 301, and the long side of the first fixed space 201 being slightly smaller than the diameter of the second fixed space 301 by 0.5 mm, when the leads of the circuit board assembly 4 pass through the smaller cross-sectional area of ​​the first fixed space 201 and the slightly larger cross-sectional area of ​​the second fixed space 301 in sequence, a controllable bending arc will naturally be generated due to the step-like change in space size. The tight clamping of the first fixed space 201 causes the leads to form an inward contraction deformation at this point, while the moderate looseness of the second fixed space 301 provides space for the leads to stretch outward. The two work together to form a stable contraction-stretching wave structure. The stress distribution generated by this deformation is uniform, which can prevent the axial sliding of the leads through structural tension and avoid damage to the wires caused by excessive bending.

[0046] like Figure 7 , Figure 8 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the central axis of the first fixed space 201 coincides with the central axis of the second fixed space 301. By designing the central axis of the first fixed space 201 to coincide with the central axis of the second fixed space 301, the leads of the circuit board assembly 4 remain on the same axis as they pass through the two fixed spaces in sequence, and the clamping force in the vertical direction can be evenly applied to both sides of the wire. This coaxial layout can prevent the leads from excessively rubbing against one side of the fixed assembly due to misalignment, reduce the risk of breakage caused by local wear of the wire sheath or uneven stress on the internal wire core, and extend the service life of the leads. Secondly, the coincidence of the central axes ensures that the positions of the two fixed spaces are precisely corresponding. When the leads enter the slightly larger second fixed space from the first fixed space with a smaller cross-sectional area, a symmetrical and controllable wavy bending shape can be formed.

[0047] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines the shape of the first fixing space 201 as an ellipse. The major axis of the elliptical first fixing space 201 is parallel to the horizontal plane, and the minor axis of the elliptical first fixing space 201 is perpendicular to the horizontal plane. By designing the first fixing space 201 as an ellipse with the minor axis set along the vertical direction, a moderate vertical clamping force can be formed on the lead wire to ensure the basic fixing effect; while the major axis extends along the horizontal direction, which not only avoids damage to the wire caused by excessive compression, but also provides a lateral buffer space for the lead wire to adapt to the slight deformation of the lead wire caused by slight shaking or temperature changes. When the first fixing space 201 cooperates with the protrusion 23, it can make the protrusion 23 contact the lead wire surface more evenly from the upper and lower sides, forming a multi-point clamping. This contact method increases the friction to prevent slippage and avoids excessive local pressure on the wire by dispersing the pressure.

[0048] like Figure 2 , Figure 11 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further defines: the circuit board assembly 4 includes a circuit board 41 and a lead wire 42. The circuit board 41 is disposed on the housing assembly 1 and located in the receiving cavity 101. One end of the lead wire 42 is disposed on the circuit board 41. The lead wire 42 passes through the first fixed space 201 and the second fixed space 301 in sequence, and abuts against the first fixed component 2 and the second fixed component 3. By fixing the circuit board lead wire 41 inside the lead wire 101 of the receiving cavity, it serves as a carrier for the core circuit element and undertakes signal processing and function control tasks. One end of the lead wire 42 is connected to the lead wire 41 of the circuit board, and the other end extends to the outside through the first fixed space 201 and the second fixed space 301, forming a physical connection channel between the internal and external circuits. This structure not only ensures the circuit continuity required for electrical functions, but also, through the cooperation of the lead wire 42 and the fixed components, constrains the circuit to a preset trajectory, avoiding poor circuit contact or functional failure caused by loose leads. Lead wire 42 passes sequentially through the first fixed space lead wire 201 and the second fixed space lead wire 301, and is tightly abutted against the two fixed components, causing the wire to form a controllable wave-shaped deformation under dual constraints. The first fixed component forms an initial clamping through the multi-point compression of the lead wire by the protrusions, and the second fixed component achieves secondary limiting through symmetrical space. The two components generate a synergistic force with the deformation of the lead wire, continuously resisting the tendency of the lead wire to slide.

[0049] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines: the outer casing assembly 1 includes a main casing 11 and an extension casing 12. The extension casing 12 is disposed on the main casing 11, the first fixing component 2 and the second fixing component 3 are disposed on the extension casing 12, and a portion of the circuit board assembly 4 is disposed on the main casing 11. The main casing 11 has a receiving cavity 101. By utilizing the lead wire 101 of the receiving cavity of the main casing 11 to provide a stable mounting space for the main body of the lead wire 4 of the circuit board assembly, it is ensured that the core components of the circuit are in a relatively closed protective environment. The lead wire 12 of the extension casing serves as a functional extension structure, not only providing a basis for the integrated installation of the lead wire 2 of the first fixing component and the lead wire 3 of the second fixing component, making the double-layer fixing structure an independent and centralized constraint unit, but also, through the connection with the lead wire 11 of the main casing, constructing a transition channel from the internal receiving cavity 101 to the external outgoing wire, guiding the lead wire 42 of the lead wire 4 of the circuit board assembly from the lead wire 11 of the main casing to the fixed space of the lead wire 12 of the extension casing, forming a continuous circuit path. This structural division not only ensures the safety protection of the internal circuitry, but also makes the installation of fixed components and the constraint of leads more targeted. At the same time, through the cooperation of the main shell and the extension shell, the sealing and mechanical stability of the overall structure are enhanced, providing a basic support for the realization of functions such as anti-slip, dustproof and waterproof.

[0050] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is also provided with a display space 103, which is used to display information of the circuit board assembly 4. By providing a display space 103 on the housing assembly 1, various data generated during the operation of the circuit board, such as status parameters and fault prompts, can be presented intuitively, making it convenient for users to understand the operating status of the equipment in real time.

[0051] Example 2

[0052] like Figures 1 to 12 As shown, this embodiment discloses an electrical appliance, including: the above-mentioned anti-slip structure for connecting wires; and an electrical appliance body, wherein the anti-slip structure for connecting wires is disposed on the electrical appliance body.

[0053] The second aspect of this application discloses an electrical appliance that significantly improves the overall operational reliability and service life of the appliance by incorporating an anti-slip structure on the appliance body. The anti-slip structure, with its double-layer fixing structure and size-adaptive fixing space, can effectively prevent poor contact or wire damage caused by slippage or loosening of the lead wire 42 of the circuit board assembly 4, thereby reducing electrical malfunctions caused by wiring problems. At the same time, its enhanced dustproof and waterproof performance provides better protection for the internal circuitry of the appliance.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
