[Detailed description of the invention] (Field of industrial application) This invention enables a terminal bracket, on which connection terminals are arranged, to be firmly fixed to the housing of an audio equipment, etc. with a simple structure and with high mounting accuracy. This invention relates to a terminal bracket mounting structure.

(Prior Art) In conventional large-scale audio equipment such as karaoke equipment, a terminal bracket has been fixed to the back of the chassis of the equipment with screws or the like. In addition, in small audio equipment, a terminal bracket is fixed to the back of the bracket of a magnetic recording/reproducing mechanism built into the housing of the equipment.

(Problems to be Solved by the Invention) In the above-described conventional terminal bracket mounting structure for large-sized audio equipment, the terminal bracket is directly fixed to the chassis, so it has excellent mounting accuracy and mechanical strength. However, the chassis must be large enough to have the depth of the casing, and the cost of materials, molds, etc. is unavoidable. In addition, the conventional mounting structure for terminal brackets of small audio equipment has a simple structure and can be manufactured at low cost, but the terminal brackets tend to move up and down.
Installation accuracy and mechanical strength are insufficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a terminal bracket mounting structure that has a simple structure and can be firmly fixed with high mounting accuracy.

(Means for Solving the Problem) In order to solve the problem, the terminal bracket mounting structure of the present invention includes a rod-shaped support fixed inside the side wall of the housing and extending to the edge of the side wall. A member, a shelf board whose one end is supported by the support member and has an L-shaped notch formed at a corner of the one end on the edge side of the side wall, and a shelf plate which is slidable on the support member facing the notch. A terminal bracket is provided with a guide that fits by movement and a guide that fits by sliding on the side of the notch on both sides, and an opening corresponding to the terminal bracket is bored and fixed to the housing. and a panel member that prevents the terminal bracket from coming off in the sliding direction.

(Function) Since one side of the terminal bracket is supported and positioned by fitting one of the guides provided on both sides to a rod-shaped support member fixed inside the side wall of the housing, at least one side of the terminal bracket is attached to the support member. It is supported with mechanical strength corresponding to the mechanical strength of , and with high positional accuracy. In addition, since the other guide is fitted into the side of the notch formed at the corner of the shelf board whose one end is supported by this support member, the terminal bracket can be secured with mechanical strength commensurate with the mechanical strength of the shelf board. The other side of is also supported.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is an exploded perspective view of essential parts of an embodiment of the terminal bracket mounting structure of the present invention, and FIG. 2 is a cross-sectional view of an audio device using the terminal bracket mounting structure shown in FIG. FIG. 3 is a diagram showing an example in which the terminal board of the terminal bracket used in the terminal bracket mounting structure of FIG. 1 and the amplification board of the magnetic recording/reproducing mechanism are integrated.

In FIG. 1, 1 is a terminal bracket;
A connecting terminal 3 is provided on the surface 2, a guide 5 having a U-shaped cross section is provided on one side 4, and a guide 5 having a U-shaped cross section is provided on the other side 4.
A notched guide 6 is formed in each of the terminal brackets 1 from the back side to the front side. The connection terminal 3 is electrically connected to a terminal board 7 provided on the terminal bracket 1 as appropriate. On the other hand, inside the side wall of the housing 8 of the audio equipment,
A rod-shaped support member 10 extending from the front panel 9 in the depth direction to the edge of the side wall on the back side of the casing 8 is fixed, and one end of a shelf board 11 is supported and fixed to this support member 10. An L-shaped cutout 12 that matches the width and depth of the terminal bracket 1 is formed at the corner of one end of the side wall of the shelf board 11 on the edge side.
Then, using the side 13 of this notch 12 as one guide, one guide 5 of the terminal bracket 1 is inserted and fitted, and the tip of the support member 10 exposed facing the notch 12 of the shelf board 11 is inserted. The terminal bracket 1 is configured so that the other guide 6 of the terminal bracket 1 can be inserted into the terminal bracket 1 by using the terminal bracket 1 as the other guide. Furthermore, a panel member 1 fixed to the back side of the housing 8
7 is provided with an opening 18 for the connecting terminal 3 of the terminal bracket 1. Note that 14 is a magnetic recording/reproducing mechanism disposed facing the front panel 9, and the amplification board 15 provided in this magnetic recording/reproducing mechanism 14 and the terminal board 7 of the terminal bracket 1 are connected to each other by lead wires 16 as appropriate. electrically connected to.

The terminal bracket mounting structure of the present invention has the above-mentioned configuration, and is assembled as follows.
First, remove the guides 5 and 6 on both sides of the terminal bracket 1.
are inserted and fitted into the side 13 of the notch 12 of the shelf board 11 and the tip of the support member 10. This results in
The terminal bracket 1 is positioned in the vertical and horizontal directions, and also in the insertion direction by the depth of the notch 12. Next, the housing 8
A panel member 17 is fixed to the back side of the. By fixing the panel member 17, movement of the terminal bracket 1 in the direction opposite to insertion and removal is restricted, and the terminal bracket 1 is fixed to the housing 8.

In this way, the terminal bracket 1 is attached to the shelf board 1.
1 side edge 13 of notch 12 and support member 10
Positioning is performed by the tip of the by the way,
The support member 10 is formed with relatively high mechanical strength to support the shelf board 11, and the shelf board 11 also generally has high mechanical strength to support other components. Therefore, one side of the terminal bracket 1 is
It is directly fitted into the support member 10 and is supported with great mechanical strength and has high positional accuracy. Also,
The other side of the terminal bracket 1 is fitted into the side 13 of the notch 12, and this side 13 is connected to the support member 1.
Since the distance from the terminal bracket 1 is relatively short and the deflection of the shelf board 11 is small, the other terminal bracket 1 is also supported with great mechanical strength and high positional accuracy. Therefore, compared to the conventional method of forming a U-shaped notch in the board and supporting both sides of the terminal bracket on both sides of the U-shaped notch, the terminal bracket of the present invention has advantages. The mounting structure is strong in terms of strength and has excellent positional accuracy. Furthermore, according to the mounting structure of the present invention, no screws or the like are used to fix the terminal bracket 1, which simplifies the effort required for fixing it.

In this way, FIG. 2 shows a cross-sectional view taken along the arrow direction of the casing of an audio equipment using the terminal bracket mounting structure of the present invention shown in FIG.

FIG. 3 shows an example in which the terminal board 7 of the terminal bracket 1 and the amplification board 15 of the magnetic recording/reproducing mechanism 14 used in the terminal bracket mounting structure of the present invention are integrated. As shown in FIG. 3, the terminal board 7 and the amplifier board 15 are integrally formed as a single board that can be divided by perforations, etc., and both boards 7 and 15 are electrically connected as appropriate by lead wires 16. ing. The terminal board 7 and the amplification board 15 are fixed to the terminal bracket 1 and the magnetic recording/reproducing mechanism 14, respectively. The magnetic recording/reproducing mechanism 14 to which both the substrates 7 and 15 in the state before division are fixed is first fixed to the front panel 9 and the shelf board 11. Next, the terminal board 7 and the amplifier board 15 are separated, the terminal bracket 1 is inverted as shown in FIGS. 1 and 2, and the terminal bracket 1 is inserted into the notch 12. Furthermore, the panel member 17 is fixed. If the terminal bracket 1 and the magnetic recording/reproducing mechanism 14 are integrated in this manner, parts management during assembly is easy.

Note that in the assembly shown in FIG. 3, the terminal bracket 1 was inverted due to the difference in the mounting height of the terminal bracket 1 and the magnetic recording/reproducing mechanism 14, but the terminal bracket 1 was not inverted and the notch 1 was
Terminal bracket 1 may be inserted into 2.

(Effect of the invention) As explained above, according to the terminal bracket mounting structure of the invention, one side of the terminal bracket
Since it is directly fitted into the support member fixed to the side wall of the housing, it can be supported with great mechanical strength and high positional accuracy. In addition, the side of the notch in the shelf board into which the other side of the terminal bracket fits is short in distance from the support member, and the shelf board does not bend much, so it is supported with great mechanical strength and high positional accuracy. .
Therefore, the terminal bracket can be supported with great mechanical strength and high positional accuracy. Furthermore, since the terminal bracket itself is fixed without using screws or the like, the assembly effort can be simplified and it is suitable for mass production.
