"Conventional technology and its problems" Audio equipment such as tape decks and CD players
As shown in the figure, it is general that the deck 1 on which a drive mechanism such as a tape or a CD is mounted is assembled to the chassis 2. Then, a pair of connectors 4a and 4b are attached to both the printed circuit board 3 fixed to the chassis 2 and the deck 1, and the connectors 4a and 4b are connected at the same time when the deck 1 is assembled to the chassis 2 and the printed circuit board 3 and It is designed to be electrically connected to the deck 1.

That is, a plurality of chassis 2 (4 in the illustrated example)
Studs 5 are provided and mounting holes 6 are formed in the deck 1 so as to correspond to the studs 5, and the positions of the connectors 4a and 4b are as shown in FIG. 6 (a). After aligning the positions of the stud 5 and the mounting hole 6, the deck 1 is pushed down and the lower surface of the deck 1 is placed on the tip of the stud 5 as shown in FIG. 6 (b), and at the same time the connectors 4a and 4b are connected. Then, the screw 7 is screwed into the mounting hole 6 and the stud 5 from the upper surface side of the deck 1 to fix them.

However, when the deck 1 is assembled to the chassis 2 as described above, both connectors 4 to be connected are to be connected.
Since the a, 4b and the studs 5 are hidden under the deck 1, it is difficult to confirm their positions. Therefore, it is not always easy to align the studs 5 with the mounting holes 6 and the connectors 4a, 4b. It was not something that could be done easily and the workability was not good.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an audio device capable of easily performing a work of assembling a deck to a chassis and a work of connecting a connector which is performed at the same time.

[Means for Solving the Problems] The present invention is designed to fix a deck equipped with a drive mechanism to the tips of a plurality of studs provided on a chassis so that the deck can be assembled to the chassis. An audio device configured such that when the deck is assembled to the chassis, a pair of connectors attached to both the printed circuit board attached to the chassis and the deck are connected. Of at least one of the studs is fitted into a mounting hole provided in the deck, and the pair of connectors is connected when they are fitted together. It is characterized by becoming.

[Operation] In the present invention, the chassis and the deck are aligned by fitting the tip of the stud provided on the chassis and the mounting hole provided on the deck, and are mounted on both of them. Since the pair of connectors are aligned, it is possible to easily perform the alignment and connection without confirming the position of the connectors.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

First, the first embodiment will be described with reference to FIGS. 1 to 3. The parts common to those of the conventional audio equipment shown in FIG. Omit it.

In this embodiment, one stud 10 of the plurality of studs provided on the chassis 2 is provided in a position close to the connector 4a attached to the printed circuit board 3 and is attached to the deck 1. The attached connector 4b has the upper end (tip) of the stud 10 described above.
The guide portion 12 is formed integrally with a mounting hole 11 that can be fitted to the stud 10.
When fitted to the upper end of the connector, the positions of the connectors 4a and 4b are naturally aligned with each other so that they can be connected.

The stud 10 is formed in a tapered shape such that the outer diameter thereof gradually decreases from the lower end to the upper end, and the inner diameter of the mounting hole 11 formed in the guide portion 12 is the outer diameter of the upper end of the stud 10. Corresponding to the above, the size is gradually increased from the upper part to the lower part, so that the upper end of the stud 10 can be easily inserted into the mounting hole 11.

When assembling the deck 1 to the chassis 2 in the audio equipment of this embodiment, if the deck 1 is placed on the chassis 2 and their positions are substantially matched, the upper end of the stud 10 is shown in FIG. As shown in FIG. 2 (b) and FIG. 3 (b), the axis of the stud 10 and the guide part are inserted into the lower part of the mounting hole 11 of the guide part 12 by itself, and therefore only the deck 1 is pushed down. 12 axes are aligned,
At the same time, the positions of the connectors 4a and 4b are naturally and accurately matched to connect them. Then, as shown in FIG.
As shown in FIG. 3B, the screw 7 is screwed into the stud 10 and the other studs 5 are also similarly screwed to complete the assembly of the deck 1 to the chassis 2.

As described above, in this embodiment, the stud 10 provided in the position close to the connector 4a and the mounting hole 11 of the guide portion 12 formed integrally with the connector 4b are fitted to each other, so that the deck 1 and the chassis 2 can be connected. Since the alignment is automatically performed and the connectors 4a and 4b to be connected are automatically aligned at the same time, it is possible to easily perform the connection work even if the positions of the connectors 4a and 4b cannot be confirmed. The workability can be greatly improved.

In the first embodiment, the stud 10 is provided at a position close to the connector 4a and the guide portion 12 is provided integrally with the connector 4b. However, this is not always the case, and the stud 10 is not necessarily provided. The guide portion 12 may be provided at a position distant from the connector 4a and provided at a position corresponding to the stud 10 on the lower surface of the deck 1 as a separate body from the connector 4b. Even in such a case, the connectors 4a and 4b are automatically aligned by fitting the stud 10 and the guide portion 12, but in that case, the deck 1
When there is room for relative rotation between the chassis 2 and the chassis 2 about the stud 10, the cross-sectional shape of the upper end of the stud 10 and the shape of the mounting hole 11 of the guide portion 12 that fits with the stud 10 are, for example, square, and the deck 1 and The deck 1 is fitted to the chassis 2 by fitting them in a state where relative rotation with the chassis 2 is impossible, or by providing at least two sets of the stud 10 and the corresponding guide portions 12 as described above and fitting them at the same time. It is desirable to configure so as to regulate the relative rotation.

The first embodiment has been described above. Next, the second embodiment will be described with reference to FIG.

In this embodiment, the upper end portion (tip portion) of the stud 20 provided at a position close to the connector 4a is fitted into the mounting hole 21 formed in the deck 1 to align the connectors 4a and 4b and The connection is made. As shown in FIG. 4 (a), the stud 20 has an outer diameter dimension at its upper end smaller than that of the other portions, and the upper end thereof is formed in the deck 1 as described above. When the connector is fitted into the connector 21, the connectors 4a and 4b are automatically aligned.

Also in this second embodiment, when the deck 1 is overlaid on the chassis 2 and the upper end of the stud 20 is inserted into the mounting hole 21 as shown in FIG. 4B, the connectors 4a and 4b are automatically aligned. Therefore, as shown in FIG. 4C, the connectors 4a and 4b are connected only by pushing down the deck 1 as it is, and even if the positions of the connectors 4a and 4b cannot be confirmed as in the case of the first embodiment, the connectors 4a and 4b are not connected. The connection can be made easily.

Also in this second embodiment, the stud 20 may be provided at a position far from the connector 4a as in the case of the first embodiment, and the stud 20 and the mounting hole 21 may not rotate relative to each other. It goes without saying that they may be fitted together or a plurality of similar studs 20 may be provided.

[Advantage of the Invention] As described in detail above, according to the present invention, the tip of at least one stud of the plurality of studs provided on the chassis is fitted into the mounting hole provided on the deck. Since it is configured so that the paired connectors are connected when they are fitted together, it is possible to easily align the deck and chassis, align the paired connectors, and connect them. Thus, the workability can be greatly improved.
