[0002] In modern electronic display touch devices, board-to-board connectors are important components for achieving electrical connections between circuit boards. However, existing board-to-board connectors have some problems in the design and manufacturing process. For example, the traditional connector terminal design may cause welding shorts or signal interference, and once a contact fails, the entire connector may not work properly. In addition, traditional connectors may be installed upside down during installation or the connector may be misaligned due to equipment vibration, which in turn affects the welding quality and contact performance.

[0034] As described in the background technology, for modern electronic display touch devices, board-to-board connectors are important components for achieving electrical connections between circuit boards. However, there are some problems in the design and manufacturing process of existing board-to-board connectors. For example, the traditional connector terminal design may cause welding short circuits or signal interference, and once a contact fails, the entire connector may not work properly. In addition, traditional connectors may be installed upside down during installation or the connector may be misaligned due to equipment vibration, thereby affecting welding quality and contact performance.

[0036] Through the above structural design, since the female connection spring piece 21 and the male connection spring piece 31 are arranged in a staggered manner, the positions between the feet are arranged to be opposite to each other, so as to avoid welding short circuit or signal interference, and effectively improve the reliability of plugging. In addition, since the female connection spring piece 21 adopts a pair of arc-shaped female contact protrusions 211, even if one female contact protrusion 211 fails, the other female contact protrusion 211 continues to conduct, so as to keep the product working normally.

[0037] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

In addition, since the female connection springs 21 use a pair of arc-shaped female contact protrusions 211, even if one of the female contact protrusions 211 fails, the other female contact protrusion 211 continues to conduct, thereby maintaining the normal operation of the product.
