The present invention relates to an electrical connector, and more particularly to an electrical connector that connects a wafer module to a printed circuit board.

Electrical connectors are widely used in the electronics field. They are used in components and components, components and systems, systems and systems in electronic devices. Electrical connections and signal transmission are essential components for a complete system. The electrical connector for receiving the wafer module generally includes a base, a cover plate assembled on the base, and a lever for driving the cover plate to slide on the base. The lever includes an operating rod and a driving rod. The operating rod and the driving rod are perpendicular to each other, and the operating rod drives the driving rod to rotate by a lever. The base is provided with a conductive terminal, and the cover plate is provided with a through hole for receiving the stitch of the wafer module. As the cover plate reciprocates relative to the base, the pins of the wafer module and the conductive terminals can be electrically connected and separated. The base is provided with a receiving slot for receiving the driving rod, and the operating rod is located on the other side of the base. A stopper is provided on the base on the same side as the operating lever to prevent the operating lever from being over-pushed. In practical applications, when the wafer module is mounted, the lever needs to be driven to 90 degrees. However, in this case, the lever is easily dropped to a position less than 90 degrees, and then inserted into the wafer module. This can result in inaccurate insertion of the wafer module or ectopic terminal of the wafer module, thereby affecting the stability of the electrical connection. Improvements have fixed the lever to 90 degrees, but the use of hard interference fixing makes the operation of the lever difficult and affects the service life of the electrical connector.
