Abstract: A connector and circuit board suitable for multiple transmission interfaces, which can be applied to storage devices or computer devices is disclosed. The connector device includes a connector case, and two transmission interfaces respectively disposed on upper and lower sides of the connector case. One end connector case serves to electrically connect with the circuit board, and another end serves as the transmission interfaces complying with at least two different specifications. Thus, the users may select suitable transmission interface according to actual needs.

Abstract: A connector adaptor suitable for various transmission protocols is disclosed. The connector includes a hollow case, two positioning sets, two terminal sets. The two positioning sets are formed on the upper side and a lower side of said hollow case. The two terminal sets are connected to the positioning sets respectively, and said terminal sets are respectively connected to a flat face of said positioning set for an electrical connection. The hollow case is made in a plastic injection process.

Abstract: A connector assembly and an adaptor for various transmission protocols are disclosed. The connector assembly comprises a hollow casing including terminal sets connected at the upper and lower inner part thereof. The hollow casing is connected to a housing with the fool-proof protrusion positioned respectively at the right and the left side thereof. The housing surrounds the hollow casing. The upper and the lower end of the housing have the elastic plate respectively. The adaptor has a hollow casing with a slot, and the slot has a positioning set. The hollow casing is surrounded by a housing. The positioning set respectively includes the terminal set at the upper and the lower side thereof. Thus one single connector assembly and the adaptor can be applied in various transmission protocols.
