CONNECTING STRUCTURE OF MODULE CASE

摘要

A connecting structure of module case has a circuit board (2), a jack (31) and a pin (41). The jack has a shaft at one end fixedly-connected to the circuit board. A spring leaf (32) is set in the plug jack. The pin is plugged into the jack, and connected to the spring leaf continuously. A slot (42) for a module case (6) is set at the end of the pin. As the module case is plugged into the slot, the pin moves ahead by overcoming the elastic force of the spring, so as to make the pin plug into the jack more deeply and increase the contact area of the pin and the spring leaf. This structure ensures effective contact of the pin and the spring leaf. Accordingly, the module case switches on the circuit board effectively, and guarantees the steady working of the module.
