A reliable power supply connection to a printed circuit board. A canted coil spring in a channel is coupled to a printed circuit board. The individual chips, electrical components and other circuits on the printed circuit board have their respective power supply terminals connected to the canted coil spring channel member. The printed circuit board can be easily slid into, and removed from a frame assembly with a high degree of reliability in making the electrical connection having a low impedance each time the circuit board is placed into the frame of the computer. Furthermore, as the board is slid into the computer, the coil spring rubs against the electrical surface to which it is going to make contact, abrading the surface and removing any debris, or buildup which may have occurred both on the power supply pad and on the spring itself. A fresh, clean metal connection is therefore made each time the printed circuit board is placed into, or removed from the computer frame. According to one embodiment, the canted coil spring is retained in a preset sloped position to ensure that it does not snag or otherwise connect to other portions of the frame when it is being removed or inserted into the system. |
