Description
Technical Field
The present invention relates to an electrical connector assembly, and more particularly to a connector assembly having an adapter for connecting two circuit boards.
Background
In the prior art, a PCB (printed circuit board) to PCB radio frequency coaxial connector combination generally includes two sockets and one adapter. Each receptacle generally includes a cylindrical outer terminal, a cylindrical center terminal, an insulator, and an insulating housing. The center terminal is disposed in the external terminal, and the insulator is disposed between the center terminal and the external terminal for supporting the center terminal and isolating the center terminal from the external terminal. The external terminal is accommodated and positioned in the insulating housing. The adapter generally includes a cylindrical outer conductor, a cylindrical center conductor, and an insulator. The center conductor is disposed in the outer conductor, and the insulator is disposed between the center conductor and the outer conductor for supporting the center conductor and isolating the center conductor from the outer conductor.
The two ends of the adapter are adapted to interface with two sockets, respectively. In the prior art, one end of the adapter is in locking engagement with one receptacle and the other end of the adapter is in sliding engagement with the other receptacle. In order to lock one end of the adapter into engagement with a receptacle, in the prior art, there are generally two solutions:
(1) One solution is to assemble the insulator of the adapter with the insulator of one of the sockets in an interference fit, thereby locking one end of the adapter with one of the sockets. A disadvantage of this solution is that the strength of the bond between the insulators is insufficient to provide sufficient mechanical retention so that one end of the adapter is easily separated from the socket.
(2) Another solution is to assemble the cylindrical outer conductor (or metal housing) of the adapter with the outer terminal of one socket in an interference fit or in a snap-fit manner, thereby locking one end of the adapter with one socket. A disadvantage of this solution is that the contact area between the cylindrical outer conductor of the adapter and the outer terminal of the socket is too large, affecting the intermodulation performance of the connector combination.
