(Prior art) To prevent radio wave interference, leakage radio waves from electronic devices are
It is particularly required that the high frequency range of 30 MHz = l O00M II z be kept low (below 30 dB). To achieve this, it is essential to strengthen the frame ground.Especially in electronic equipment that handles high-frequency pulses, the shield coating of external interface cables and the power supply circuit built into the equipment and various units such as Fronbi disk drives are strengthened. It is necessary to connect the metal case etc. to the shield frame which is mainly grounded with low impedance.

In the conventional structure, the metal case and connector mounting bracket of each unit are fixed to the shield frame with screws, and the cover plate that covers the opening of the shield frame is simply fixed to the main frame with screws. In order to reduce assembly man-hours, the structure uses as few fixing screws as possible. However, such a structure cannot satisfy the noise shielding effect against high frequency components, and in order to obtain a sufficient shielding effect, it is necessary to adopt a multi-point contact structure between the metal case or connector mounting bracket and the shield frame. be.

Therefore, as a structure to realize multi-point contact between the connector mounting bracket and the shield frame, there are two ways to achieve multi-point contact between the connector mounting bracket and the shield frame. Structures that realize multi-point contact by contacting the shield frame are known.

(Problem to be solved by the invention) However, with the structure in which the connector mounting bracket is fixed to the shield frame with multiple screws, when the number of printed boards increases, it becomes extremely troublesome to attach and remove the printed boards during assembly and maintenance. In addition, the structure in which the contact spring is provided on the connector mounting bracket has the disadvantage that the connector mounting bracket becomes large and the distance between the printed boards arranged in parallel increases, making it difficult to operate the device with a large number of printed boards. There are drawbacks that impede miniaturization.
