Background technique

An electronic card connector, which can be used to accommodate cards with digital content such as SIM cards or SD cards, which is installed on an electronic device, and the card and connector plugging methods can be divided into horizontal plugging and vertical plugging As well as oblique plug connection, in light and thin portable products, the oblique plug connection method is the most suitable, because the oblique plug-in structure is simple, the appearance is light and thin, and the oblique plug-in direction will not be blocked by the internal components of the device. This allows engineers to have a greater degree of freedom in design, and the oblique insertion is to prevent the card from being backed out by fixing the card between multiple elastic terminals and a housing through the interference force formed between them.

However, in order to ensure that the electronic card is not easy to fall off during use, the clamping force between the elastic terminal and the housing is usually too large. When the electronic card is withdrawn, it is easy to scratch the metal contact part on the electronic card. The electroplating coating with good conductivity on the terminal is scraped off, or the electronic card is deformed, resulting in poor contact. In addition, when installing or removing the electronic card, it is necessary to apply a force that resists friction. The problem causes discomfort in use, or the electronic card falls due to carelessness.

Therefore, in order to prevent the electronic card from being damaged due to excessive clamping force and to provide a better operating feel, it is necessary to provide an electronic card connector with a small clamping force and to ensure that the electronic card is not easy to fall off.
