JPH0927372A - Noise reduction structure of electronic apparatus connector board - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce a leak of electric wave noise generated in a device toward the outside from an opening portion without deteriorating workability at a cable connection time by blocking an opening portion through turning a connector board for cable connection. SOLUTION: In the case of connecting an external cable 4 to a connector board 1 of a housing 2, the board 1 is in a vertically standing-up state against an opening portion 6 of a bottom face 5 so that a worker can easily connect the cable 4 to the board 1. On a termination of the cable 4 connection, a worker turns the board 1 around a hinge 9 so as to fix the board to a bottom surface by a screw 11. At that time, a conduction packing 12 provided on the periphery of the opening portion 6 of the bottom face 5 is flattened so that the gap produced between the bottom face 5 and the board 1 is eliminated. Thereby, it is possible to reduce a leak of electric wave noise generated inside the housing 2 toward the outside from the opening portion 6 of the bottom face 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noise resistance structure for an electronic equipment connector board.

[0002]

2. Description of the Related Art In conventional electronic equipment, a large opening is provided on the bottom surface of the device in order to introduce an external cable into the device, but radio noise generated from the inside of the device is radiated to the outside from the opening. In order to prevent it, it was necessary to surround the opening with a shielding plate.

[0003]

In the above-mentioned conventional technique, it is necessary to surround the opening with a shielding plate in order to prevent noise from being radiated to the outside from the opening for receiving the external cable. However, there was a problem that the external cable could not be completely enclosed due to the difficulty of connecting the external cable, and the radio noise generated inside the device was leaking from the opening toward the outside.

[0004]

In a noise reduction structure for an electronic device connector board according to the present invention, a connector capable of closing the opening by providing an opening provided with a conductive packing and a hinge on an end face and rotating the same. A board and a spiral for performing extra length processing when the connector board is rotated are provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1A and 1B are a schematic side view and a perspective view showing an embodiment of the present invention. The structure of this embodiment has an opening 6 in which a conductive packing 12 is provided around the bottom surface 5 of a housing 2 of an electronic device in order to receive an external cable 4.
And a connector board 1 capable of closing the opening 6 by providing a hinge 9 on the end face and rotating around the hinge 9.

The internal connector 7 provided at the tip of the internal cable 8 of the housing 2 is fixed to the connector board 1 and the external connector 3 provided at the tip of the external cable 4.
The external cable 4 and the internal cable 8 are connected by inserting the connector into the internal connector 7 of the connector board 1.

Further, the external cable 4 is provided with a spiral 10 for performing extra length treatment when the connector board 1 rotates about the hinge 9, and when the connector board 1 is standing up, the spiral 10 is extended and the connector is extended. When the board 1 is closed, the spiral 10 is contracted.

Next, the usage of the above structure will be described. When the external cable 4 is connected to the connector board 1 of the housing 2, the connector board 1 stands upright with respect to the opening 6 of the bottom surface 5 and a worker easily connects the external cable 4 to the connector board 1. be able to.

When the connection of the external cable 4 is completed, the operator rotates the connector board 1 around the hinge 9 to move the bottom surface 5
Secure with screws 11. At that time, the conductive packing 12 provided around the opening 6 of the bottom surface 5 is crushed to eliminate the gap between the connector boards 1 of the bottom surface 5 and the radio noise generated inside the housing 2 is reduced. It is possible to reduce leakage of moisture from the opening 6 of the bottom surface 5 to the outside of the housing 2.

In this embodiment, the conductive packing is used, but any elastic member having elasticity like a spring made of a metal plate and having electrical conductivity may be used.

[0012]

As described above, according to the present invention, the connector board for connecting the cables is rotated to close the opening, so that the working time at the time of connecting the cables is not increased and the working time is extended. It is possible to reduce the leakage of the radio noise generated in the device from the opening to the outside without the need.
