technical field

The present invention relates to an electrical connection structure, in particular to a seamed electrical connection structure which uses a sewing method to achieve electrical connection.

Background technique

With the advancement of technology and the changes in people's expectations for textiles, the traditional textile industry must not only pursue technological innovation from time to time, but also gradually strengthen its technological integration with other industries. Among them, with the vigorous development of the electronics industry, the combined application of textiles and electronic products is the main development trend of the textile industry in recent years. People's requirements for textiles are not only the original functions such as simple coverage and warmth preservation, but also hope to further integrate electronic products on textiles to increase life entertainment, convenience and portability. However, limited by the fact that electronic products are not as soft and washable as fabrics, and it is difficult to achieve aesthetics in visual design, many bottlenecks have formed the difficulties faced by the combination of these two industries.

Generally speaking, the method of combining electronic components (such as LED) or circuit boards with fabrics is nothing more than embedding metal wires in the fabrics, and electrically connecting the metal wires with the fabrics, electronic components and power sources. The combination of the metal wire and the electronic component can be soldered or matched with a female connector. However, in this design, whenever the user washes the fabric, it is necessary to remove the electronic components, so as to prevent the electrical connection between the pins of the electronic components and the metal wires from being broken or short-circuited after repeated washing or pulling, or even poked. Piercing the outer surface of the fabric.

To sum up, providing a structure that uses textile methods to achieve electrical connections, and applying it to textiles, increasing the elasticity of the combination of fabrics and electronic components, and further improving the beauty and practicality of clothing is a relevant technology industry. urgently needed goal.
