Description

[Detailed description of the invention] This invention relates to an improvement in the structure of the recorder body of an underwater detector such as an echo sounder or a fish finder.

Conventionally, the structure of a recorder case for an underwater detector is
As shown in the figure, a box-shaped case body A;
It consists of a box-shaped lid B that covers and closes the opening of the case body, the case body A and the lid B.
The structure is such that the opening surfaces of the two sides face each other and are sealed with a waterproof gasket C or the like interposed therebetween. As for the operating mechanical parts and the like housed inside, an electronic component D is attached to the case body A, and an underwater detection signal recording device F is attached to the inner surface of the lid B.

However, when manufacturing the housing of the above structure,
It is necessary to mold both the main body A and the cover B separately, which has the disadvantage that the manufacturing costs are very high. In addition, if the case is made of synthetic resin, which has poor thermal conductivity, it is necessary to drill separate ventilation holes for dissipating heat from the internal machinery or to embed a heat sink within the thickness of the case body, which makes manufacturing cumbersome.

In view of the above-mentioned drawbacks, this invention was devised for the purpose of providing a structure for an underwater detector recorder that is very easy to manufacture and has good heat dissipation properties for internal equipment. It consists of a metal substrate that can be attached to the substrate, and a box-like case body that is attached to cover the surface of the substrate, one side of the substrate is folded diagonally along a fold line parallel to the edge, and the surface of the substrate is In addition to having circuit components attached thereto, the box-like case body is characterized in that a recording device for underwater detection signals and a window hole for viewing the recording of the recording device are provided on the side surface of the box-like case body.

This invention will be explained below using examples.

Figure 2 is an exploded perspective view of an embodiment of this invention;
The figure is a sectional view of the embodiment.

The enclosure structure (hereinafter simply referred to as "enclosure structure") of the underwater detector recorder of this invention is a metal substrate that can be attached to the supporting wall surface W with fastening members 1, 1, etc. such as bolts, nuts, and screws. 2, and a box-shaped case body 3 attached to cover the surface of the board 2, the metal board 2 has one side 2A folded up diagonally along a fold line 2B parallel to the edge, and Electronic circuit components 4 are attached to the surface of the board 2, and the side surface 3A of the box-shaped case body 3
is provided with a window hole 3B for viewing the recording device 4A.

Note that, as is well known, the electronic circuit component 4 has necessary circuit elements arranged on a printed circuit board, and the printed circuit board is mounted on the metal substrate 2, but this will be omitted.

Furthermore, the metal substrate 2 and the box-like case body 3 are fixedly attached to each other by screwing screws 6 into the columnar member 5 attached to the metal substrate 2, as shown in FIG. It is constructed so that it can be opened and closed by being attached by a hinge 7 and connected by a hinge 7.

In FIG. 3, reference numeral 8 denotes an arm with a stopper for adjusting the opening angle so that the box-shaped case body 3 does not open too tightly.

In addition, the structure of the enclosure of this invention is suitable for mounting on a flat wall surface W as shown in Figures 2 and 3.
As shown in Fig. 4, a wall surface W having a storage recess W'
It can also be installed on.

In this case, it is convenient to integrally form flange-like projecting edges 9, 9 on the front side edge of the box-like case body 3, since the gap H of the storage recess W' can be hidden.

When a recording device, electronic circuit components, etc. are attached using the structure of the housing of this invention, a gap P is created between the power cord, signal cord 10, etc. and the wall surface created by the folded portion of the metal substrate 2. Insert and connect.

In this case, even if the wall surface W is arranged horizontally as shown in FIGS. 3 and 4, a gap P is created, so that cords can be easily connected. Note that, as shown in FIG. 5, if the window hole 3B is made freely openable and closable so that the internal display device 4A can be taken out, it will be convenient to replace the recording paper and the like.

This idea is structured as above, so
When molding the case, only one box-shaped case body needs to be molded, and the manufacturing effort is about half that of the conventional case, making it possible to manufacture it at a very low cost. In addition, since the electronic circuit component 4 is mounted on the metal substrate 2, it has good heat dissipation properties, and does not require any special means for heat dissipation unlike conventional methods. It has various practical effects, such as being easy to manufacture because it only needs to be bent.
