ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a radio frequency (RF) connector assembly for attaching to a printed circuit board (PCB), and particular to an RF connector assembly having a back cover and an insert-molded lead frame assembly firmly mounted at a rear thereof.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 6,053,744 utilizes a two-step moulded interconnect device (MID) molding process where radio frequency (RF) connectors are connected to the PCB with plated plastic. The adapter in this prior patent comprises a plastic body which has a plated body area, a plated through hole and solder tabs connecting the plated body area to be directly connected to traces on a PCB. An electrical contact attains an interference fit with the plated through hole, providing a first electrical signal path communicating between the contact and the plated through hole to the solder tab. An outer shell of the RF connector mates with a connector interface of the adapter, providing a second electrical signal path communicating between the outer shell of the RF connector and solder tabs via the plated body area and the connector interface. The first and second signal paths could then be connected to the PCB by the solder tabs, respectively.
However, this is a very complicated and expensive product, which will produce large amount of production scrap and long lead time.
Hence, an improved RF connector is needed to overcome the above-mentioned deficiencies of current RF connectors.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a Radio Frequency (RF) connector assembly having a back cover to reliably secure contacts.
Another object of the present invention is to provide a RF connector assembly having a back cover which firmly retains a lead frame assembly in position.
An RF connector assembly in accordance with the present invention comprises a die cast housing, a plurality of RF coaxial contacts, two insert-molded lead frame assemblies and a back cover with a pair of arms. The die cast housing includes a pair of side walls each defining a slot therein, a front wall and a rear wall defining a plurality of inner and outer passageways. The lead frame assemblies are made by insert-molding lead contacts into an insulative portion. The lead frame assemblies are installed in the inner and outer passageways of the die cast housing. The arms of the back cover are latched in the corresponding slots of the side walls. The back cover has two pairs of inner and outer ribs, each outer rib defining a pair of pits for accommodating the inner conductors of the coaxial contacts.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
