Therefore, when the transmission module is connected to the insulating body, the press-contacting portions of the adapting terminals can be elastically contacted with the connecting ends of the plurality terminals, so that the transmission module is electrically connected to the terminals of the insulating body.
However, the wireless transmission module of the above wireless transmission apparatus has a circuit unit in the transmission module electrically connected to the signal transmission portion and the signal processing portion. And the circuit unit has a plurality of welding portion for the adapting terminals welded thereto. Thus, the adapting terminals need to be additionally manufactured and then welded to the circuit unit. Such a process is inconvenient and the cost thereof can not be decreased. In addition, since the adapting terminals need to be arranged to contact against the adapting terminals on the insulating body, the adapting terminal needs to be bent and forms a press-contacting surface, such that the thickness of the wireless transmission module can not be decreased.
Therefore, a novel stacked connector apparatus is needed, it can be composed of a plurality of connectors and wireless module as wall as the types of the wireless module can be arbitrary changed and the usability can be increased. Besides, the manufacturing cost can be lowered and the dimensions of the product can be downsized.
