Description

Technical Field

[0001] This utility model relates to the field of touch screen connection devices, and more particularly to a capacitive touch screen cable that is resistant to electromagnetic interference. Background Technology

[0002] Capacitive touchscreen technology works by sensing the electrical current of the human body. To achieve multi-touch, capacitive touchscreens rely on adding mutual capacitance electrodes. Simply put, the screen is divided into sections, and a set of mutual capacitance modules is set up in each area, each working independently. Therefore, the capacitive touchscreen can independently detect the touch situation in each area, process it, and easily achieve multi-touch. Capacitive touchscreens usually need to be used with a dedicated touchscreen cable. The touchscreen cable is a conductive wire mainly used to convert the touch signals on the touchscreen into electrical signals for processing. Touchscreen cables are widely used in various devices, especially in industrial control and production line monitoring.

[0003] For example, patent number (CN208538518U) discloses an EDP screen cable for touch screens, including a wire with connectors at both ends. The wire surface is injection-molded with a waterproof layer, and waterproof connectors are provided at both ends of the waterproof layer. The waterproof connectors and the waterproof layer are integrally injection-molded, and both the waterproof layer and the waterproof connectors are made of soft plastic material. The wire includes a core and a heat-shrink tubing. The heat-shrink tubing is fitted onto the core, which is wrapped with a shielding layer composed of a conductive material. The core is an enameled wire, and the shielding layer is copper foil. The core serves as the main material for electrical connection, and the conductive material wrapped around it acts as a shielding layer, providing electromagnetic interference protection. The heat-shrink tubing is fitted onto the core with the conductive material wrapped around it. Heating the heat-shrink tubing causes it to shrink, thus tightening the core to ensure the minimum wire diameter. The outermost layer uses an integrally injection-molded waterproof connector and waterproof layer, providing 100% waterproof protection.

[0004] Currently, capacitive touchscreen cables are susceptible to electromagnetic interference due to limitations in their circuit structure. Furthermore, the cables themselves are often messy and difficult to organize, further impacting their performance and ease of use.

[0005] Therefore, considering that the aforementioned capacitive touchscreen cables are susceptible to electromagnetic interference during use and that the cables themselves are messy and difficult to manage, further affecting the normal use and convenience of the capacitive touchscreen cables, a capacitive touchscreen cable that is resistant to electromagnetic interference and easy to manage can be designed.

The braided layer is made of tin-plated copper wire, which forms a tight metal mesh and also has a good shielding effect. The insulating shielding layer is made of cross-linked conductor shielding material, which can improve the electric field on the conductor surface. The adjustable strap wraps around the neatly stacked wires and can be used with the connecting sleeve to achieve binding and fixation. The connecting sleeve can pass through the adjustable strap. The return spring can drive the connecting plate and the squeezing block to fit tightly against the adjustable strap. The anti-slip texture can improve the friction between the squeezing block and the adjustable strap.

[0009] As a preferred option, the circuit protection sleeve is made of PVC polyvinyl chloride, and the braided layer is made of tin-plated copper wire.

[0010] Preferably, the anti-interference layer is made of aluminum foil shielding material, and the insulating shielding layer is made of cross-linked conductor shielding material.

[0014] Preferably, the connecting rod is slidably connected to the movable cavity, and the connecting plate is slidably connected to the movable cavity.

[0015] The beneficial effects of this utility model are:

[0016] This electromagnetic interference-resistant capacitive touchscreen cable utilizes an aluminum foil shielding layer, which has excellent conductivity and reflectivity, and is particularly effective at shielding against high-frequency electromagnetic interference. The braided layer, made of tin-plated copper wire, forms a tight metal mesh that also provides good shielding, preventing electromagnetic interference during use and ensuring the cable's proper functioning. After arranging the cable neatly, the adjustable strap is wrapped around the folded cable, allowing it to be easily threaded through the connecting sleeve. A return spring then causes the connecting plate and the pressing block to tightly hold the adjustable strap in place, securing the cable and improving the ease of use and maintenance of the capacitive touchscreen cable.
