Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection device for a composite device that uses a combination of a parent device and a child device that are used independently.

Conventionally, composite audio equipment has been configured to be used as a tape recorder with a radio, for example, by combining a radio main unit as a parent device, or a tape recorder main unit as a parent device and a radio main unit as a child device. Yes, when combining both devices that can be used independently in the composite audio device,
Electrical connections were made to a connector section consisting of multiple pin jacks and pin plugs.

The present invention aims to provide a composite device connection device that takes up a small space and can reliably connect both devices even if a slight positional shift occurs between the parent device and the child device when they are combined, in place of the conventional connector section. Another object of the present invention is to provide a connection device for a composite device that prevents the connection portion from picking up external induced noise, dielectric hum, etc. when the child device is used separately from the parent device.

In the figure, 1 is a radio main unit (i.e., the main device) having a storage recess 2 in the center and speakers 3, 3', etc. on the left and right sides of the radio main unit, and 4 is stored in the storage recess 2 of the radio main unit 1. The main body of the tape recorder (i.e., slave device) can be used independently. In the tape recorder main body 4, a plurality of connection conductive patterns 6 are formed at predetermined pitches on a printed circuit board 5 inside the tape recorder main body 4, and a housing 7 (in this case, the back A plurality of slits 8 are formed in the lid portion in correspondence with the respective connection conductive patterns. In addition, the radio main body 1 has a plurality of electrically connected conductive patterns 6 for connection, which are exposed to the outside of the tape recorder main body housing 7 through the slits 8 in the storage recess 2. Connecting elastic tongue pieces 9 are provided. Furthermore, 10,1
0' is a guide protrusion provided in the storage recess 2 of the radio main body 1, and when the tape recorder main body 4 is stored in the storage recess 2, the tape recorder main body 4 is They are fitted into guide grooves 11 and 11' formed on the side surfaces, respectively, and serve as guides so that the tape recorder main body 4 is reliably accommodated.

Therefore, according to the connection device of the present invention, when the tape recorder main body 4 is stored in the storage recess 2 of the radio main body 1, each of the connection conductive patterns 6... and connecting elastic tongue piece 9...
The circuit parts of the radio body 1 and the tape recorder body 4 can be electrically connected to each other through electrical and elastic contact with the tape recorder, allowing the tape recorder to function as a radio-equipped tape recorder.

In addition, in the present invention, as shown in FIG. 4, a comb-shaped shielding printed circuit board is formed with a shielding conductive pattern 12 on the upper surface and a plurality of slits 13 corresponding to each of the connection conductive patterns 6. 14 is superimposed on the printed circuit board 5 in the tape recorder main body 4, and when the tape recorder main body 4 is used separately from the radio main body 1, the shield print 14 can be used to cover the casing. It is constructed so that external dielectric noise through each slit 8 of the body absorbs dielectric hum and the like. The shielding printed circuit board 14 is attached to the printed circuit board 5 by caulking using eyelets 15, 15, and the shielding conductive pattern 12 connects the printed circuit board 5 to the ground conductive pattern through the eyelets 15, 15. It is electrically connected to a pattern (not shown).

Therefore, when the tape recorder main body 4 is separated and used as a portable device, even if, for example, a finger or the like faces the connection conductive patterns 6 through the slits 8 of the housing 7, the human body It is possible to prevent dielectric noise, dielectric hum, etc. caused by the above-mentioned connection conductive patterns 6 from being induced and affecting the audio signals, etc. Further, according to the present invention, when the shielding printed circuit board 14 is superposed on the printed circuit board 5, each slit 13 of the shielding printed circuit board 14 is
Since each of the conductive patterns for connection 6 is made to look through the upper surface through the conductive pattern for connection, there is no risk of interfering with the connection with the elastic tongue-like piece for connection 9, and furthermore, the conductive pattern for shielding is 12 is formed inside the outer periphery of each slit 13, so there is no risk that each of the connecting elastic tongues 9 will inadvertently come into contact with the shielding conductive pattern 12. Furthermore, according to the present invention, the shielding printed circuit board 14
There is also the additional effect that the thickness of the plate serves to restrict the position of each of the connecting elastic tongues 9.

In this embodiment, the tape recorder main body has been described as a slave device, but conversely, the radio main body can be removed or assembled with the tape recorder main body as a parent device.

As described above, according to the connecting device of the present invention, when used in combination with a parent device, the plurality of connection conductive patterns formed on the internal printed circuit board are connected to the outside of the casing in order to electrically connect with the parent device. Since the shielding printed circuit board is separately superposed and provided on the printed circuit board of the child device facing the main device, when the child device is used separately from the parent device, the shielding printed circuit board can be used to separate each part of the casing. It is possible to absorb external induced noise, dielectric hum, etc. through the slit, and prevent such induced noise, dielectric hum, etc. from being directly guided to each of the connection conductive patterns and affecting the audio signals, etc. The effect is of high practical value.
