ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical adapter, and particularly to an electrical adapter for joining two electrical connectors having different designs and configurations.
2. Description of the Prior Art
A computer mainframe and its periphery device, for example, a monitor is usually electrically connected together by a cable connector assembly, wherein the cable connector assembly has two connectors at its two ends with one connector being used to mate with an electrical connector of the monitor and the other being used to mate with an electrical connector of the computer mainframe.
As the computer technology evolves, new type monitors (for example, digital monitors) with advanced functions are developed which are equipped with connectors having a different configuration in comparison with that of the old ones. To connect the computer mainframe with the new type monitor, an adapter is necessary whereby the cable in the present use can be utilized. The adapter includes two connectors in both ends wherein one is configured suitably for mating with the connector in the new type monitor, and the other is so configured that it can mate with the cable connector assembly.
The connectors of the conventional adapter are usually interconnected using a flat cable, a single printed circuit board (PCB), or discrete conducting wires. The conductors of the flat cable and the discrete conducting wires for interconnection need to be connected with terminals of the connectors by soldering, respectively, thereby decreasing production efficiency and complicating production procedure.
When one of the connectors of the adapter has more than two rows of terminals, to mount such terminals onto a single board having two circuit faces is relatively difficult.
Therefore, an improved adapter is desired.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide an adapter wherein one of the connectors which has more than two rows of terminals can be easily and economically connected to another connector having terminals arranged in less rows.
An adapter in accordance with the present invention comprises two connectors and an adapting device. The adapting device comprises two PCBs and a plurality of conducting pins. The two connectors have terminals being arranged in rows of different numbers and having different configurations.
The PCBs each have a plurality of through holes. The through holes of one PCB are aligned with the through holes of the other PCB and the conducting pins are inserted through and retained in the aligned through holes.
The two PCBs register each other on one end thereof and are contacted with three-row terminals of one of the two connectors on three surfaces of these ends thereof. The other end of one of the PCBs is straddled by and contacted with two rows of terminals of the other one of the two connectors on two surfaces thereof.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
