Anti-slip conductive copper foil conductive tape

Abstract

This utility model belongs to the field of conductive tape and discloses an anti-slip conductive copper foil conductive tape, including: a roll of conductive tape, and a first abutment and a second abutment. The first abutment and the second abutment are detachably installed on the outer sides of the two end faces of the conductive tape. The first abutment and the second abutment are used to cover the end faces of the conductive tape to form a physical barrier between the end faces and the external environment. The first abutment and the second abutment are installed on the exposed ends of the conductive tape on both sides, thereby forming a physical barrier between the side walls of the conductive tape and the outside air. This facilitates continuous dust protection for the exposed end faces of the side walls of the conductive tape. After the conductive tape is used, the relative position of the conductive tape and the first abutment and the second abutment remains unchanged. Therefore, continuous dust protection can still be provided for the sides of the conductive tape even after a portion of the conductive tape has been used.

Description

Technical Field

[0001] This disclosure pertains to the field of conductive tapes, specifically relating to conductive copper foil conductive tapes for anti-slip applications. Background Technology

[0002] Copper foil tape is a type of metal tape primarily used for electromagnetic shielding. It comes in two types: electrical signal shielding and magnetic signal shielding. Electrical signal shielding relies mainly on the excellent conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" on the adhesive surface of the copper foil tape to achieve the magnetic shielding effect. Therefore, it is widely used in mobile phones, laptops, and other digital products.

[0003] Currently available double-sided conductive copper foil tapes mainly consist of release paper, a conductive adhesive layer, and a copper foil layer. When rolled, both ends (i.e., the cross-section) of the tape roll are completely exposed. Because the conductive adhesive layer on the ends is directly exposed to the air and has strong adhesion, it easily attracts dust, fibers, and other impurities from the environment during storage and transportation, resulting in noticeable black marks on the ends. This not only severely affects the product's appearance but may also affect its critical conductivity and shielding effect due to contaminant migration.

[0004] For example, a tear-resistant double-sided conductive copper foil tape with publication number CN222647288U uses disposable dustproof strips to cover the ends of the tape roll. However, once these strips are removed, they cannot be restored, and their dustproof function is limited to the first use after the product leaves the factory. They are insufficient to provide continuous protection for the tape roll during use, especially for the newly exposed ends after use. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a conductive copper foil conductive tape for anti-slip applications. This solves the problem of easy contamination caused by the continuous exposure of the tape roll end face in existing technologies, as well as the problem that the diameter of the conductive tape changes continuously after use, and that if the dustproof device is directly fixed to the side wall of the conductive tape, it will interfere with the pulling out of the open end of the conductive tape.

[0006] The objective of this disclosure can be achieved through the following technical solutions:

[0007] The conductive copper foil conductive tape for anti-slip purposes includes: a roll of conductive tape, and a first abutment and a second abutment. The first abutment and the second abutment are respectively installed on the outer sides of the two end faces of the conductive tape in a detachable manner. The first abutment and the second abutment are used to cover the end faces of the conductive tape to form a physical barrier between the end faces and the external environment.

[0008] In some publicly available designs, a support cylinder penetrating the middle of the conductive tape is provided in the middle of the second blocking part.

[0009] In some disclosures, the disassembly method is a snap-fit ​​connection, the end of the support cylinder is provided with a slot, and the first abutment part is provided with an elastic claw that cooperates with the slot.

[0010] In some disclosures, the disassembly method is a magnetic connection, with a magnetic suction element provided at the end of the support cylinder, and a metal part on the second abutment part that cooperates with the magnetic suction element.

[0011] In some disclosures, the disassembly method is a threaded connection, with a threaded groove through which the conductive tape passes through the middle of the first abutment, and a threaded protrusion on the second abutment that mates with the threaded groove.

[0012] In some disclosures, the support cylinder has a countersunk hole at one end near the second abutment, and the threaded groove is formed inside the countersunk hole. After the threaded protrusion engages with the threaded groove, the inner wall diameter of the support cylinder is equal to the outer wall diameter of the threaded protrusion.

[0013] In some disclosures, the diameters of the first and second blocking portions are larger than the maximum diameter of the conductive tape when it is not in use.

[0014] In some disclosures, a contact assembly is provided between the first blocking part and the second blocking part, and the lower end of the contact assembly is attached to the outer end face of the conductive tape.

[0015] In some disclosures, the contact assembly includes a support frame, an elastic element, and a slider. The support frame is fixed to the side of the first abutment near the conductive tape, and an elastic element pointing towards the center of the conductive tape is provided on the inner side of the support frame. A slider is fixed to the lower end of the elastic element, and the lower section of the slider contacts the hinged outer wall.

[0016] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0017] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0018] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0019] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0020] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0021] The beneficial effects of this disclosure are:

[0022] The first and second blocking parts are installed on the exposed ends of the conductive tape on both sides, thereby forming a physical barrier between the side walls of the conductive tape and the outside air. This facilitates continuous dust protection for the exposed end faces of the side walls of the conductive tape. After the conductive tape is used, the relative positions of the conductive tape and the first and second blocking parts remain unchanged. Therefore, continuous dust protection can still be provided for both sides of the conductive tape even after a portion of the conductive tape has been used.

[0023] Meanwhile, the first and second blocking sections can be detachably installed on the outside of the conductive tape. For users who need to use conductive tape in large quantities and for extended periods (such as electronics manufacturers and repair shops), a one-time investment in a few protective structures can provide continuous protection for all their tape rolls. This helps reduce the need to repeatedly pay for dust protection for each new roll of conductive tape. Attached Figure Description

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0032] Please refer to Figures 1 to 5 The conductive copper foil conductive tape for anti-slip purposes includes: a roll of conductive tape 1, and a first blocking part 2 and a second blocking part 3. The first blocking part 2 and the second blocking part 3 are respectively installed on the outer side of the two end faces of the conductive tape 1 in a detachable manner. The first blocking part 2 and the second blocking part 3 are used to cover the end faces of the conductive tape 1 to form a physical barrier between the end faces and the external environment.

[0033] By providing a first blocking part 2 and a second blocking part 3 on the outer sides of both ends of the conductive tape 1, with the first and second blocking parts attached to the side walls of the conductive tape 1, a physical barrier is formed between the side walls of the conductive tape 1 and the outside air, thus providing continuous dust protection for the exposed end faces of the side walls of the conductive tape 1. Furthermore, both the first blocking part 2 and the second blocking part 3 are made of rigid materials, such as plastic or metal shells, which helps protect the conductive tape 1 during transportation. The first blocking part 2 and the second blocking part 3 are detachable; after purchase, if the user intends to carry it with them or use it for a short period, the first blocking part 2 and the second blocking part 3 can be detached to reduce the weight of the conductive tape 1. Additionally, when a roll of conductive tape 1 is used up, the user can install the first blocking part 2 and the second blocking part 3 onto a subsequently purchased roll of conductive tape 1 for reuse, saving costs and increasing the practicality of the first blocking part 2 and the second blocking part 3.

[0034] Please refer to Figures 3 to 4 A support cylinder 31 that penetrates the middle of the conductive tape 1 is provided in the middle of the second blocking part 3.

[0035] The support cylinder 31 is coaxially mounted on the inner side of the conductive tape 1, and the distance between the first abutment 2 and the second abutment 3 is greater than the width of the conductive tape 1. This makes it possible for external forces to press the conductive tape 1 along the axial direction of the conductive tape 1 when the conductive tape 1 is piled up. The pressure on the first abutment 2 and the second abutment 3 on the conductive tape 1 will concentrate the pressure on the support cylinder 31, thereby reducing the squeezing force on the conductive tape 1. The support cylinder 31 increases the stability of the paper tube in the middle of the conductive tape 1.

[0036] First Embodiment

[0037] Please refer to Figures 1 to 3The disassembly method is a snap-fit ​​connection. The end of the support cylinder 31 is provided with a slot 41, and the first abutment part 2 is provided with an elastic claw 42 that cooperates with the slot 41.

[0038] The elastic claw 42 is made of plastic. When the elastic claw 42 on the first stop part 2 is aligned with the end of the support cylinder 31 and axial pressure is applied, after the elastic claw 42 is inserted into the slot 41, the elastic claw 42 first deforms and then elastically recovers, so that the end of the claw is embedded in the slot 41, thereby connecting the first stop part 2 and the second stop part 3. In addition, the conductive tape 1 itself acts as a guide structure, which helps to improve the coaxiality of the first stop part 2 and the second stop part 3 during installation, and further improves the ease of installation.

[0039] Second Embodiment

[0040] Please refer to Figure 5 The disassembly method is magnetic connection. The end of the support cylinder 31 is provided with a magnetic suction component 51, and the second abutment part 3 is provided with a metal part 52 that cooperates with the magnetic suction component 51.

[0041] When the user needs to assemble the first stop 2, the second stop 3, and the conductive tape 1, they only need to roughly align the first stop 2 and the second stop 3 with the hollow center of the conductive tape 1. After the magnetic attractor 51 and the metal part 52 enter the effective magnetic force range, the strong magnetic attraction generated between them will automatically guide the second stop 3 to move to the accurate position and complete the adsorption and fixation. The magnetic force between the metal part 52 and the magnetic attractor 51 connects and fixes the first stop 2 and the second stop 3.

[0042] Third Embodiment

[0043] Please refer to Figure 4 The disassembly method is a threaded connection. The first abutment 2 has a threaded groove 61 that passes through the conductive tape 1 in the middle, and the second abutment 3 has a threaded protrusion 62 that cooperates with the threaded groove 61.

[0044] When assembling the protective structure, the user aligns the threaded protrusion 62 on the second stop 3 with the threaded groove 61 on the support cylinder 31 of the first stop 2. By rotating the second stop 3, the threaded protrusion 62 is tightened inside the threaded groove 61. This continues until both sides of the conductive tape 1 are in contact with the side walls of the first stop 2 and the second stop 3. To disassemble, simply rotate the second stop 3 in the opposite direction. The threaded connection allows for a tighter connection between the first stop 2 and the second stop 3. Furthermore, when replacing conductive tape 1 with different widths, the user can stop tightening before the threaded protrusion 62 reaches the bottom of the threaded groove 61, thus accommodating conductive tapes 1 of varying widths.

[0045] Please refer to Figure 4The support cylinder 31 has a countersunk hole 63 at one end near the second abutment 3, and a threaded groove 61 is formed inside the countersunk hole 63. After the threaded protrusion 62 engages with the threaded groove 61, the inner wall diameter of the support cylinder 31 is equal to the outer wall diameter of the threaded protrusion 62.

[0046] When the threaded protrusion 62 is screwed down to the lowest position, the end of the threaded protrusion 62 fits against the inner wall of the countersunk hole 63. At this time, it can increase the axial force resistance of the support cylinder 31 and the threaded protrusion 62, so as to reduce the stress concentration at the threaded connection caused by excessive axial pressure, thereby causing thread damage. This is beneficial to the service life of the threaded connection under high pressure.

[0047] The diameters of the first blocking part 2 and the second blocking part 3 are greater than the maximum diameter of the conductive tape 1 when it is not in use.

[0048] It is beneficial to fully wrap the side wall of the conductive tape 1. The first blocking part 2 and the second blocking part 3 are like a "protective skirt" for the conductive tape 1. This not only prevents external dust from entering the side wall of the conductive tape 1 and causing the conductive tape 1 to turn black, but also reduces the direct scratches of the conductive tape 1 by sharp objects, which is beneficial to further improve the protection of the conductive tape 1.

[0049] A contact assembly 7 is provided between the first blocking part 2 and the second blocking part 3, and the lower end of the contact assembly 7 is attached to the outer end face of the conductive tape 1.

[0050] Under the action of the internal elastic element, the lower end of the contact assembly 7 is always subjected to radial pressure perpendicular to the outer wall of the conductive tape 1, thereby maintaining continuous and tight elastic contact with the outer circumferential surface of the conductive tape 1.

[0051] As the conductive tape 1 is pulled out and consumed, the outer diameter of the conductive tape 1 gradually decreases. Driven by the pressure of the elastic element 72, the contact assembly 7 will automatically and continuously move towards the center. When the end of the conductive tape 1 cannot be found, it can help the user quickly and accurately locate the position of the end of the conductive tape 1 and make it easy to lift it up.

[0052] The contact assembly 7 includes a support frame 71, an elastic element 72, and a slider 73. The support frame 71 is fixed on the side of the first abutment 2 near the conductive tape 1, and the elastic element 72 pointing to the center of the conductive tape 1 is provided on the inner side of the support frame 71. The lower end of the elastic element 72 is fixed with a slider 73, and the lower section of the slider 73 contacts the hinged outer wall.

[0053] In use, the support frame 71 is installed on the side wall of the first stop part 2 in a fixed or sliding manner. The elastic restoring force of the elastic element 72 drives the slider 73 to move closer to the conductive tape 1, and the bottom edge of the slider 73 is always in contact with the outer end face of the conductive tape 1. If the contact assembly 7 is fixedly connected to the first stop part 2, the conductive tape 1 is rotated so that the contact assembly 7 rotates around the conductive tape 1 with the central axis of the conductive tape 1 as the center. This allows the end of the slider 73 to fit tightly against the outside of the conductive tape 1. When the slider 73 has obvious damping or stops, the slider 73 is located near the end of the conductive tape 1, which makes it easy to find the end of the conductive tape 1, similar to finding the end of the conductive tape 1 with a fingernail. The trigger component 7 is equivalent to the fingernail part.
