Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screens, and in particular to an elastic conductive connection structure for anti-electromagnetic interference capacitive touch screens. Background Technology

[0002] A capacitive touchscreen is a technology that uses changes in the capacitance of the human body or other conductive bodies to achieve touch positioning. When a finger touches the screen, the human body itself carries an electrostatic field, which changes the electric field distribution on the touch panel. This change in electric field causes a change in the electric field at the touch location, thereby causing a change in capacitance.

[0003] The existing capacitive touchscreen elastic conductive connection structure typically uses a single conductive film as an assembly. When damaged, the entire assembly needs to be replaced, rather than replacing the damaged area individually. This results in high repair costs and unnecessary waste.

[0004] Therefore, the existing capacitive touchscreen elastic conductive connection structure typically uses a single, assembled conductive film. When damaged, the entire structure needs to be replaced, rather than replacing individual damaged areas. This results in high repair costs and unnecessary waste. An electromagnetic interference-resistant capacitive touchscreen elastic conductive connection structure can be designed. By incorporating movable films, a modular conductive connection structure can be formed. Each movable film and its surface components constitute a single module. When damaged, the individual movable film can be disassembled and replaced by peeling off the corresponding adhesive strip, eliminating the need to replace the entire structure and reducing repair costs. Utility Model Content

[0005] To overcome the problem that the existing capacitive touch screen's elastic conductive connection structure usually uses a single, assembled conductive film, which requires the entire assembly to be replaced when damaged, rather than replacing the damaged area individually, resulting in high repair costs and unnecessary waste.

[0006] The technical solution of this utility model is: an anti-electromagnetic interference capacitive touch screen elastic conductive connection structure, including a substrate; it also includes movable films, adhesive strips, slots, glue strips and conductive components. Multiple movable films are provided on the upper surface of the substrate. Adhesive strips are connected to both the front and rear ends of the movable films. Slots are provided on the upper surface of the substrate corresponding to the positions of the adhesive strips. Adhesive strips are provided on the bottom surface of the substrate at the side positions of multiple slots. The adhesive strips are bonded to the corresponding adhesive strips. Conductive components are provided on the upper surface of the movable films.

[0007] Preferably, by setting up movable films, a modular conductive connection structure can be formed. Each movable film and its surface components are a single module. When damage occurs, the individual movable film can be disassembled and replaced by peeling off the corresponding adhesive strip from the surface of the adhesive strip, without having to replace the whole thing. This reduces maintenance costs and solves the problem that in the existing capacitive touch screen elastic conductive connection structure, the conductive film is usually a whole assembly. When damage occurs, the whole assembly needs to be replaced, and it is not possible to replace the damaged point individually, resulting in high maintenance costs and unnecessary waste.

[0008] Preferably, the conductive component includes a socket and an elastic conductor. The upper surfaces of the substrate and the movable membrane are respectively provided with a plurality of arrayed sockets, and the interior of the socket is provided with an elastic conductor.

[0009] Preferably, the elastomeric conductor is made of silicone rubber.

[0010] Preferably, the outer surface of the elastomeric conductor is coated with a conductive coating by electroplating.

[0012] Preferably, the substrate is made of an insulating soft film material.

[0013] Preferably, the adhesive strip is bonded to the movable membrane with glue.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up movable films, a modular conductive connection structure can be formed. Each movable film and its surface components are a single module. When damage occurs, the corresponding adhesive strip can be peeled off from the surface of the adhesive strip to disassemble and replace the individual movable film without replacing the whole unit, thus reducing maintenance costs. This solves the problem that the existing capacitive touch screen elastic conductive connection structure usually uses a single, assembled conductive film. When damage occurs, the entire assembly needs to be replaced, and individual replacement of the damaged point is not possible, resulting in high maintenance costs and unnecessary waste.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of an anti-electromagnetic interference capacitive touchscreen elastic conductive connection structure, including a substrate 1; it also includes movable films 2, adhesive strips 3, slots 4, glue strips 5, and conductive components. Multiple movable films 2 are disposed on the upper surface of the substrate 1, and adhesive strips 3 are connected to both ends of the movable films 2. Slots 4 are provided on the upper surface of the substrate 1 corresponding to the positions of the adhesive strips 3. Adhesive strips 5 are disposed on the sides of the multiple slots 4 on the bottom surface of the substrate 1, and the adhesive strips 5 are bonded to the corresponding adhesive strips 3. Conductive components are disposed on the upper surface of the movable films 2. By setting the movable films 2, it is possible to... A modular conductive connection structure is formed, with each active film 2 and its surface components being a single module. When damage occurs, the individual active film 2 can be disassembled and replaced by peeling the corresponding adhesive strip 3 from the surface of the adhesive strip 5, without having to replace the entire structure. This reduces maintenance costs and solves the problem that the existing capacitive touch screen elastic conductive connection structure usually uses a single conductive film assembly. When damage occurs, the entire assembly needs to be replaced, and individual damaged points cannot be replaced, resulting in high maintenance costs and unnecessary waste.

[0023] Please see Figures 1-4 In this embodiment, the conductive component includes a socket 61 and an elastic conductor 62. A plurality of arrayed sockets 61 are correspondingly provided through the upper surfaces of the substrate 1 and the movable membrane 2. An elastic conductor 62 is disposed inside each socket 61. By providing the sockets 61, the elastic conductor 62 can be positioned and installed to form a complete induction array. The elastic conductor 62 is made of silicone rubber. Using silicone rubber to make the elastic conductor 62 provides a high degree of cushioning when compressed. The outer surface of the elastic conductor 62 is electroplated with a conductive coating. This conductive coating on the outer surface of the elastic conductor 62 enables it to possess excellent conductivity, thereby meeting the application requirements.

[0024] Please see Figures 1-4 In this embodiment, the movable membrane 2 and the substrate 1 are connected by thermosetting adhesive. By using thermosetting adhesive to fix the movable membrane 2 and the substrate 1, multiple movable membranes 2 can be positioned, preventing the position of the movable membrane 2 from shifting during use. The substrate 1 is made of insulating soft film material. By using rolled soft film material to make the substrate 1, the substrate 1 can have insulating properties, so as not to affect the normal use of the elastic conductor 62. The adhesive strip 3 is bonded to the movable membrane 2 with glue. By using glue to connect the adhesive strip 3 and the movable membrane 2, the fixing strength of the connection point can be improved, and loosening can be prevented.

[0025] During operation, the elastic conductor 62 can be positioned and installed by setting the socket 61 to form a complete induction array. By using silicone material to make the elastic conductor 62, the elastic conductor 62 can have a high buffering effect when squeezed. By setting a conductive coating on the outer surface of the elastic conductor 62, it can have excellent conductivity to meet the usage requirements. By using thermosetting adhesive to fix the movable membrane 2 to the substrate 1, multiple movable membranes 2 can be positioned to avoid the position of the movable membrane 2 shifting during use. By using rolled soft film material to make the substrate 1, the substrate 1 can have insulation properties, so as not to affect the normal use of the elastic conductor 62.

[0026] Through the above steps, a modular conductive connection structure can be formed by setting the active film 2. Each active film 2 and its surface components are a single module. When damage occurs, the corresponding adhesive strip 3 can be peeled off from the surface of the adhesive strip 5 to disassemble and replace the individual active film 2 without replacing the whole structure. This reduces maintenance costs and solves the problem that the existing capacitive touch screen elastic conductive connection structure usually uses a single conductive film assembly. When damage occurs, the entire assembly needs to be replaced, and individual replacement of the damaged point is not possible, resulting in high maintenance costs and unnecessary waste.
