As shown in FIGS. 2 to 4, the holding body 2 is made up of a bottom plate 4 and upper plates 6 and 6 formed so as to be continuous on both sides of the bottom plate 4, and is made of resin or the like in a direction orthogonal to the chassis 1. It is formed integrally.

As shown in FIGS. 2 and 3, a window frame 3 having an opening 3a smaller than the relay port 1a of the chassis 1 is formed in the holding body 2 between the front and back of the chassis 1. As shown in FIG. 1, the holding body 2 has a substantially C-shaped holding portion 2 a formed on one end side (front side) of the chassis 1.
The holding portion 2a positions and holds the relay board 8.

One end (right side) is attached to the tip of the holding portion 2a.
The guide 2b is connected only to This guide part 2b
Is for guiding and holding the insertion of the relay board 8 into the holding section 2a. That is, the relay board 8 is guided to the holding section 2a by sliding in a state substantially corresponding to the guide section 2b.

The guide portion 2b is formed with a convex locking portion 5 on the upper surface of the bottom plate 4 of the holder 2. This locking part 5
As shown in FIGS. 1 to 3, a plurality of (two in this example) are formed in a row near the entrance and exit of the holder 2. The locking portion 5 engages with an engagement hole 9 of the relay board 8 described later to lock the relay board 8 to the holder 2.

Further, as shown in FIG. 1, FIG. 3, and FIG. 4, the pair of upper plates 6 of the holder 2 have tapered portions 7 at their tip sides (the entrance and exit sides of the holder 2). Formed. The tapered portion 7 is formed such that the thickness of the upper plate 6 decreases from the base end side to the distal end side of the upper plate 6.

1, 3 and 4 are provided on the upper plate 6. As shown in FIG.
As shown in FIG. 5, a regulating surface 6a connected to the tapered portion 7 is formed on the base end side thereof in a substantially parallel shape with the bottom plate 4. This regulatory surface 6
The distance between a and the bottom plate 4 is set to be slightly larger depending on the thickness of the relay board 8.

As shown in FIG. 4, the inclination of the tapered portion 7 and the height and position of the locking portion 5 are set so that the relay substrate 8 can be stored in the holding portion 2a when the relay substrate 8 is mounted on the holder 2. Is set. 2d is a reinforcing rib for reinforcing the support of the holder 2 (see FIG. 3).

A relay board (substrate) 8 for relaying wiring between the front and back of the chassis 1 is integrally formed of resin or the like. As shown in FIG. 1, the relay board 8 is formed in a thin plate shape, and is substantially L-shaped so that its planar shape substantially corresponds to the shape of the holder 2. As shown by the two-dot chain line in FIGS. 2 and 3, the thickness and the width of the relay board 8 are set slightly smaller than those of the holder 2.

As shown in FIG. 1, an engagement hole 9 having a diameter slightly larger than the engagement portion 5 of the holder 2 is formed in the relay substrate 8 at its rear end side.
Is formed. The engagement holes 9 are respectively formed at positions where the engagement holes 9 engage with the locking portions 5 when the relay board 8 is mounted on the holder 2 as shown by the two-dot chain lines in FIGS. 2 and 3. . Solder portions 8a and 8b are formed on one surface of the relay board 8 at both ends in the short direction, and these solder portions 8a and 8b are formed.
The conductor 8c is formed between them.

As shown in FIG. 1, the relay board 8 is formed with a tapered surface 8d at the corner at the tip. The tapered surface 8d is formed to facilitate insertion of the relay board 8 into the holder 2.

In order to mount the relay board 8 on the holder 2, as shown in FIG. 1, the relay board 8 is inserted with the tip of the relay board 8 facing the entrance of the holder 2. At this time, the relay board 8 is inserted along the bottom plate 4. When the relay board 8 is moved along the guide portion 2b, the relay board 8 is naturally guided to the holding portion 2a. In other words, the tapered surface 8d of the relay board 8 and the end face 2c of the holder 2 are in contact with each other, and the tip of the relay board 8 is regulated so as to face the entrance of the holder 2.

Subsequently, when the relay board 8 is inserted, as shown in FIG. 4, the relay board 8 is restricted by the tapered portion 7 (or the locking portion 5), and the tapered portion 7 and the locking portion 5 are connected to each other. Move between. Further, when the relay board 8 is inserted to a position where the engagement hole 9 and the locking portion 5 correspond to each other, that is, a position near the insertion end position (a position shown by a solid line in FIG. 4), the relay board 8 is Due to the regulation of the regulating surface 6a, the elastic deformation slightly in the clockwise direction.

When the relay board 8 is inserted to the insertion end position, as shown by the two-dot chain line in FIG. 2 and the solid line in FIG. 3, the relay board 8 is moved by the elastic force as shown by the solid line in FIG. And the engaging hole 9 and the engaging portion 5 are engaged. Thereby, the relay board 8 is held by the holder 2.

The relay board 8 at the insertion end position is shown in FIG.
As shown by the dotted line and the solid line in FIG. 3, the rear end slightly protrudes from the holder 2. That is, the position of the locking portion 5, the shape of the relay board 8, and the like are set such that the rear end of the relay board 8 slightly projects from the holder 2 when the relay board 8 is mounted on the holder 2.

The reason why the rear end of the relay board 8 is projected from the holder 2 when the relay board 8 is mounted is that the rear end can be hooked with a finger or the like when the relay board 8 is removed, so that the relay board 8 can be easily pulled. This is so that it can be pulled out.

Further, as shown by the two-dot chain line in FIG. 2, the end of the relay board 8 at the insertion end position is slightly apart from the window frame 3. This is because, when the relay board 8 is attached or detached, as shown in FIG. 4, the tip of the relay board 8 is inclined and the tip of the relay board 8 in the inclined state is released.

For example, an unillustrated relay wire soldered to the soldering portion 8a is led out from the opening 3a of the window frame 3. Then, for example, a head wire (not shown) soldered to the soldering portion 8b is connected to a head (not shown) provided on the front side of the chassis 1, and a relay wire is connected to an amplifier (not shown) provided on the back side of the chassis 1, respectively.

To remove the relay board 8 from the holder 2,
Perform the installation in the reverse order. That is, the locking portion 5 and the locking hole 9
In order to release the engagement from the state in which is engaged (the state shown in FIG. 3), the rear end of the relay board 8 protruding from the holding body 2 is moved to the tapered portion 7 side (see FIG. 4). ).

When the relay board 8 is pulled out in this state, the state shown in FIG. 4 is changed from the solid line state in FIG. 4 to the state shown in FIG. On this occasion,
The relay board 8 is pulled out along the tapered portion 7 while escaping to the tapered portion 7 side. That is, the tapered portion 7 guides when the relay board 8 is mounted, and also, when the relay board 8 is pulled out.
Is to make a miss.

According to this embodiment, since the tapered portion 7 guides when the relay board 8 is mounted and escapes the relay board 8 when pulling out, the relay board 8 is inserted into the holder 2 only by inserting the relay board 8 into the holder 2. The engagement portion 5 integrally formed with the connector 2 engages with the engagement hole 9 of the relay substrate 8, and the relay substrate 8 is held by the holder 2.
Therefore, according to this example, a screw or the like for fixing the relay board 8 to the chassis 1 is not required, and the relay board 8 can be quickly and easily attached to and detached from the chassis 1. Also, since the bottom plate 4 is formed between the upper plates 6 and 6,
At the time of insertion, the relay substrate 8 can be placed along the upper surface of the bottom plate 4 anywhere between the upper plates 6 and 6, and the relay substrate 8 can be reliably and easily inserted into the holder 2.

Further, according to the present embodiment, since the retaining portion 5 for retaining the relay board 8 is formed on the holding body 2, the relay substrate 8 is inserted along the tapered portion 7 so that the retaining portion is naturally formed. 5, the relay board 8 is positioned on the holding portion 2a, and the positioning of the relay board 8 at the time of mounting can be facilitated.

Further, according to the present embodiment, since the relay port 1a is formed in the chassis 1 and the holder 2 is disposed in the relay port 1a, the relay board 8 can be accommodated inside the chassis 1 and the tape recorder can be accommodated. And the like can be miniaturized. Further, according to the present embodiment, since the relay board 8 is disposed inside the chassis 1, it is possible to prevent the head wires, the relay wires, and the like from slipping on the end surface of the chassis 1 or being damaged by being hooked on other parts, The yield can be improved.

In the above-described embodiment, the holder 2 is molded (outsert molded) on the chassis 1 in advance, but the attachment of the holder to the chassis is not limited to this. Further, the shapes, positions, and the like of the locking portion and the tapered portion are not limited to those in the above-described embodiment. In this case, the relay board can be locked to and detached from the holder by the locking portion and the tapered portion.

Further, in the above embodiment, the relay board for relaying wiring between the front and back of the chassis is shown as the board, but the board is not limited to this.

[0038]

According to the invention, the tapered portion is formed near the entrance of the holder for holding the substrate and the like so as to face the tapered portion. It is possible to escape when removing the substrate or the like. Therefore, according to the present invention, a screw or the like for fixing the board or the like to the chassis is not required, so that the board or the like can be quickly and easily attached to or detached from the chassis. In addition, since the bottom plate is formed between the upper plates, when inserting, the substrate etc. can be placed along the upper surface of the bottom plate as long as it is between the upper plates, and the substrate etc. can be securely and easily inserted into the holder. can do.

Further, according to the present invention, since the board or the like is inserted along the tapered portion of the holding body and naturally locked to the locking portion, the board or the like is positioned on the holding body and can be positioned at the time of mounting.
