Description

Technical Field

[0001] This utility model relates to the field of aluminum substrate edge protection, specifically an aluminum substrate edge protection structure with an insulating buffer layer. Background Technology

[0002] Aluminum substrates are widely used in critical components such as circuit boards and heat dissipation modules due to their excellent thermal conductivity and lightweight properties. However, the edges of aluminum substrates are easily damaged by external forces such as collisions and friction during processing, transportation, or use, leading to problems such as edge warping and exposure of the conductive layer. This not only affects the structural stability of the equipment but may also cause electrical faults such as short circuits. Therefore, a special edge protection structure is required.

[0003] In existing technologies, edge protection of aluminum substrates often employs simple adhesive strips. However, traditional adhesive strips suffer from the following problems: poor adhesion between the strip and the aluminum substrate edge. Due to potential shape differences such as protrusions or curvatures at the aluminum substrate edge, gaps easily form due to poor fit. These strips are prone to detachment after prolonged use or exposure to vibration, failing to provide continuous and effective protection. Furthermore, due to the limited cushioning capacity of the strip, it easily transfers energy directly to the aluminum substrate edge upon impact, failing to effectively reduce the risk of damage. These problems severely impact the lifespan of the aluminum substrate and the reliability of the equipment. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an edge protection structure for an aluminum substrate with an insulating buffer layer, so as to solve the technical problems of poor edge protection of aluminum substrates due to poor adaptability of the adhesive strip and poor buffering effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an edge protection structure for an aluminum substrate with an insulating buffer layer, used for the protection of the edge of a circular or rectangular aluminum substrate, comprising an adhesive strip disposed on the outer periphery of the circular or rectangular aluminum substrate, wherein the end of the adhesive strip is provided with a plug-in component for locking the shape formed by the adhesive strip.

[0006] The plug-in assembly includes a female connector and a plug, both of which have assembly slots for inserting adhesive strips.

[0007] Preferably, the adhesive strip is made of insulating material, and two snap-fit ​​flexible strips are symmetrically arranged on the side of the adhesive strip.

[0008] When the two snap-fit ​​strips are joined together, they form a snap-fit ​​connection with the edge of the circular or rectangular aluminum substrate.

[0009] Preferably, an adapter groove is provided between the two snap-fit ​​strips to form a combination with a circular or rectangular aluminum substrate with different raised edges.

[0010] Preferably, the adhesive strip has at least two strip-shaped buffer cavities and a plurality of rectangular buffer cavities.

[0011] Preferably, when the rubber strip is impacted, the strip-shaped buffer cavity and the rectangular buffer cavity are in a compressed state.

[0012] Preferably, the connecting female is provided with a plug groove, and a plurality of pressure strips made of elastic material are rotatably provided in the connecting female.

[0013] When the pressure bar is squeezed, it is in a compressed state and has the potential to spring outward.

[0014] Preferably, the connector plug has a plug strip fixed to its exterior to form a plug slot, and a pressure plate is provided at the top of the connector plug, with a locking block fixed at the top of the pressure plate.

[0015] The pressure plate is made of elastic material, and the top of the inner part of the connecting female seat is provided with a slot for the locking block to engage.

[0016] When the plug strip and the plug slot are in the plugged state, the pressing strip abuts against the bottom end of the connector plug, and the locking block engages with the locking slot in the connector socket.

[0017] In summary, the present invention has the following main advantages: 1. This utility model uses strip-shaped and rectangular buffer cavities set inside the adhesive strip to absorb impact energy through compression deformation, directly reducing the risk of damage to the edge of the aluminum substrate by external force. At the same time, the adhesive strip made of insulating material can block current conduction, preventing short circuits caused by the edge of the circular or rectangular aluminum substrate coming into contact with conductive materials, thus achieving dual protection of mechanical protection and electrical safety.

[0018] 2. This utility model can adapt to circular or rectangular aluminum substrates with different raised edges through the adapter groove of the snap-fit ​​strip, which has high adaptability and can ensure that the strip is tightly attached to the edge of the aluminum substrate. The plug-in assembly firmly fixes the shape of the strip by the bidirectional locking of the pressing strip and the locking block, preventing the strip from falling off or shifting during use and improving the long-term stability of the protective structure. When it is necessary to disassemble or replace the strip, simply press the pressure plate to disengage the locking block from the locking groove, then slide the plug-in strip to disengage the connector from the connector socket, and then disengage the strip from the snap-fit ​​of the circular or rectangular aluminum substrate.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Example 1 Please see Figure 1 and combined Figures 3-6 This utility model provides a technical solution: an edge protection structure for an aluminum substrate with an insulating buffer layer, used for protecting the edge of a circular aluminum substrate 11. It includes an adhesive strip 2 disposed on the outer periphery of the circular aluminum substrate 11, and an insertion component 3 at the end of the adhesive strip 2 for locking the circle formed by the adhesive strip 2. By locking the circle formed by the adhesive strip 2 with the insertion component 3, the adhesive strip 2 is prevented from falling off or shifting during use, ensuring that the protective structure continuously adheres to the edge of the circular aluminum substrate 11.

[0024] The plug-in assembly 3 includes a female connector 31 and a plug connector 32. Both the female connector 31 and the plug connector 32 are provided with assembly slots for inserting the adhesive strip 2, which facilitates the assembly operation.

[0025] Furthermore, the adhesive strip 2 is made of insulating material, and two snap-fit ​​flexible strips 21 are symmetrically arranged on its side. When the two snap-fit ​​flexible strips 21 are joined together, they form a fastening connection with the edge of the circular aluminum substrate 11. The adhesive strip 2, made of insulating material, can block current conduction, and the snap-fit ​​flexible strips 21 fastening the edge of the circular aluminum substrate 11 can provide a basis for subsequent insertion and locking.

[0026] Furthermore, an adapter groove 22 is provided between the two snap-fit ​​strips 21 to form a combination with the circular aluminum substrate 11 with different raised edges. The adapter groove 22 can adapt to different raised edges, ensuring that the adhesive strip 2 fits tightly with the edge of the circular aluminum substrate 11, avoiding protective gaps caused by differences in edge shape, and improving versatility.

[0027] Furthermore, two strip-shaped buffer cavities 23 are formed in the adhesive strip 2, and several rectangular buffer cavities 24 are formed in the adhesive strip 2. The strip-shaped buffer cavities 23 and the rectangular buffer cavities 24 absorb impact energy through compression deformation, reducing the direct effect of external force on the edge of the circular aluminum substrate 11.

[0028] Furthermore, when the adhesive strip 2 is impacted, the strip-shaped buffer cavity 23 and the rectangular buffer cavity 24 are compressed. This directly dissipates the impact energy and prevents the energy from being transferred to the edge of the circular aluminum substrate 11.

[0029] Furthermore, the connector 31 has a insertion slot 311, and several pressure strips 312 made of elastic material are rotatably disposed in the connector 31. When the pressure strips 312 are squeezed, they are in a compressed state and have the potential energy to spring outward. After being squeezed and compressed, the elastic pressure strips 312 have the potential energy to spring outward, which can form a continuous abutment force with the bottom end of the connector 32 to prevent the connection from becoming loose.

[0030] Furthermore, a connector strip 321 is fixed to the outside of the connector plug 32 to form a connection with the connector groove 311. A pressure plate 322 is provided at the top of the connector plug 32, and a locking block 323 is fixed at the top of the pressure plate 322. The pressure plate 322 is made of elastic material, and a locking groove for the locking block 323 to engage is opened at the top of the inside of the connector female 31. When the connector strip 321 and the connector groove 311 are in the plugged state, the pressure strip 312 abuts against the bottom end of the connector plug 32, and the locking block 323 engages with the locking groove in the connector female 31. The elastic pressure plate 322 drives the locking block 323 to engage in the slot, forming a bidirectional lock with the abutting force of the pressure strip 312. This ensures that the plug-in assembly 3 remains firmly connected under vibration or external force. When it is necessary to disassemble or replace the adhesive strip 2, simply press the pressure plate 322 to disengage the locking block 323 from the slot, then slide the plug-in strip 321 to disengage the connector plug 32 from the connector female 31, and then disengage the adhesive strip 2 from the snap-fit ​​of the circular aluminum substrate 11.

[0031] Example 2 Please see Figure 2 and combined Figures 3-6Furthermore, in conjunction with Embodiment 1, an edge protection structure for an aluminum substrate with an insulating buffer layer is obtained for protecting the edge of a rectangular aluminum substrate 12. This structure includes an adhesive strip 2 disposed around the outer periphery of the rectangular aluminum substrate 12, with a locking assembly 3 at the end of the adhesive strip 2 to lock the rectangle formed by the adhesive strip 2. By locking the rectangle enclosed by the adhesive strip 2 with the locking assembly 3, the adhesive strip 2 is prevented from falling off or shifting during use, ensuring that the protective structure continuously adheres to the edge of the rectangular aluminum substrate 12 and improving the reliability of the protection.

[0032] The plug-in assembly 3 includes a female connector 31 and a plug connector 32. Both the female connector 31 and the plug connector 32 are provided with assembly slots for inserting the adhesive strip 2.

[0033] Furthermore, the adhesive strip 2 is made of insulating material, and two snap-fit ​​flexible strips 21 are symmetrically arranged on its side. When the two snap-fit ​​flexible strips 21 are joined together, they form a snap-fit ​​with the edge of the rectangular aluminum substrate 12. The adhesive strip 2, made of insulating material, can block current conduction and prevent the edge of the rectangular aluminum substrate 12 from contacting conductive materials and causing a short circuit; the snap-fit ​​flexible strips 21 snap onto the edge of the aluminum substrate, initially fixing the position of the adhesive strip 2 and providing a basis for subsequent insertion and locking.

[0034] Furthermore, an adapter groove 22 is provided between the two snap-fit ​​strips 21 to form a combination with rectangular aluminum substrates 12 with different raised edges. The adapter groove 22 can adapt to different raised edges, ensuring that the adhesive strip 2 fits tightly with the edge of the rectangular aluminum substrate 12, avoiding protective gaps caused by differences in edge shape, and improving versatility.

[0035] Furthermore, the adhesive strip 2 has two strip-shaped buffer cavities 23 and several rectangular buffer cavities 24. The strip-shaped buffer cavities 23 and the rectangular buffer cavities 24 absorb impact energy through compression deformation, reducing the direct effect of external force on the edge of the rectangular aluminum substrate 12, and achieving effective buffering of mechanical impact.

[0036] Furthermore, when the adhesive strip 2 is impacted, the strip-shaped buffer cavity 23 and the rectangular buffer cavity 24 are compressed. This prevents energy from being transferred to the edge of the rectangular aluminum substrate 12, thus providing active protection for the rectangular aluminum substrate 12 from a mechanical perspective.

[0037] Furthermore, the connecting female 31 has a insertion groove 311, and several pressure strips 312 made of elastic material are rotatably disposed in the connecting female 31. When the pressure strips 312 are squeezed, they are in a compressed state and have the potential energy to spring outward. After being squeezed and compressed, the elastic pressure strips 312 have the potential energy to spring out, which can form a continuous abutment force with the bottom end of the connecting plug 32, preventing the plug from becoming loose and improving the locking strength of the plug assembly 3.

[0038] Furthermore, a connector strip 321 is fixed to the outside of the connector plug 32 to form a connection with the connector slot 311. A pressure plate 322 is provided at the top of the connector plug 32, and a locking block 323 is fixed at the top of the pressure plate 322. The pressure plate 322 is made of elastic material, and a slot for the locking block 323 to engage is provided at the top of the inside of the connector female 31. When the connector strip 321 is in the plugged state with the connector slot 311, the pressure strip 312 abuts against the bottom end of the connector plug 32, and the locking block 323 engages with the slot in the connector female 31. The elastic pressure plate 322 drives the locking block 323 to engage in the slot, forming a bidirectional lock with the abutment force of the pressure strip 312, ensuring that the connector assembly 3 remains firmly connected under vibration or external force, further improving the stability of the protective structure.

[0039] The working principle of this utility model is as follows: First, an adhesive strip 2 made of insulating material is wrapped around and attached to the outer periphery of a circular aluminum substrate 11 or a rectangular aluminum substrate 12. Two snap-fit ​​flexible strips 21 symmetrically arranged on the side of the adhesive strip 2 are merged and form a snap-fit ​​with the edge of the circular aluminum substrate 11 or the rectangular aluminum substrate 12. At this time, the adapter groove 22 opened between the two snap-fit ​​flexible strips 21 can adapt to the circular aluminum substrate 11 and the rectangular aluminum substrate 12 with different protruding edges, ensuring that the adhesive strip 2 is tightly attached to the edge of the aluminum substrate.

[0040] Subsequently, both ends of the adhesive strip 2 are inserted into the assembly slots of the connector 31 and connector 32 in the plug assembly 3, respectively, to complete the initial positioning of the shape formed by the adhesive strip 2. When the plug strip 321 of the connector 32 is inserted into the plug slot 311 of the connector 31, the several elastic pressure strips 312 rotatably arranged inside the connector 31 are compressed. Since the pressure strips 312 have the potential energy to spring outward, they can press against the connector 32, thereby ensuring the stability of the connection. At the same time, the elastic pressure plate 322 at the top of the connector 32 drives the locking block 323 to engage with the locking groove inside the connector 31, forming a two-way locking, and finally firmly fixing the shape formed by the adhesive strip 2.

[0041] When the edge of the aluminum substrate is impacted by an external force, the strip-shaped buffer cavity 23 and the rectangular buffer cavity 24 inside the adhesive strip 2 are compressed and absorb the impact energy through cavity deformation, thereby achieving buffer protection for the edge of the aluminum substrate.

[0042] When it is necessary to disassemble or replace the adhesive strip 2, simply press the pressure plate 322 to disengage the clip 323 from the slot, then slide the connector strip 321 to disengage the connector plug 32 from the connector female 31, and then disengage the adhesive strip 2 from the snap-fit ​​between the circular aluminum substrate 11 or the rectangular aluminum substrate 12.
