Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a package mounting device for mounting a package such as a marine sensor in a watertight container.

(Prior art) Conventionally, this type of device was
It had a package mounting structure that was easy to install and remove without using screws.

FIG. 3 is a perspective view showing such a conventional package mounting device, and FIG. 4 is a sectional view of the mounting portion thereof.

In the figure, 1 is a package cage (hereinafter simply referred to as a package cage) in which a plurality of holes 1a are drilled along one edge and components are mounted on a flat plate or board;
Reference numeral 2 denotes a base having a vertical part 2a and a horizontal part 2b, which is provided inside the case to attach this package. 3 is a holding block fixed to the lower part of the vertical part 2a of this base 2, and 4 is implanted in the upper part of the vertical part 2a of this base 2 at a position corresponding to the hole 1a made in the package 1. 5 is a highly elastic wire spring that is entwined with this pin 4 in a zigzag pattern.
Further, the holding block 3 has a receiving groove 3 having a wedge-shaped cross section for holding one end of the package 1, that is, the end opposite to the end where the hole 1a is formed.
Further, the pin 4 is provided with a flange 4a at its head for locking the wire spring 5 entangled in the zigzag pattern described above.

To attach and fix the package cage with this structure, insert the end of the package cage 1 on the side where the hole 1a is not made into the receiving groove 3a, place the package cage 1 so that the hole 1a fits into the pin 4, and then attach the wire spring 5 to the pin. 4, the pin 4 has an enlarged part 4b, which positions the package 1, and also has an enlarged part 4b.
Since the wire spring 5 has a tapered portion 4c that extends from the flange 4a to the flange 4a, the wire spring 5 is pressed against the package cage 1 side along this taper, so that the package cage 1 can be fixed without play.

(Problem that the invention aims to solve) However, with the above structure, when the package cage is to be installed in a watertight container such as a marine sensor, the base that stops the package cage is attached integrally to the flange of the container in a cantilevered manner. A package cage is installed on this base, but in order to increase the number of components to be mounted, it was necessary to attach them to both sides of the base, or to extend the base and attach a long package cage. If the packages are attached separately to both sides of the base, it is necessary to wire between the packages, which increases costs and reduces work efficiency for attaching and removing. In addition, when attaching a long package cage to a long base, the long base has the disadvantage that the structural strength of the base itself decreases, the holding power of the package cage decreases, and the ocean sensor becomes vulnerable to vibrations and shocks. .

The present invention eliminates the increase in cost, decrease in work efficiency, and decrease in package installation strength when trying to install an expanding package as described above,
It is an object of the present invention to provide a package mounting device that can securely attach a package at low cost.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a package mounting device for a marine sensor, etc., which includes a case, a lower flange provided at the bottom of the case, and a lower flange having a guide groove. an upper flange provided at the upper part of the case and having a guide groove; and an upper flange arranged at the center of the case to form a holding part, and a portion of the inner surface of the case has elastic force at multiple locations. A part made of foamed foam having a shape such that they come into contact with each other is provided, a package is disposed between the upper flange and the lower flange, and the central part of the part is held between the clamping parts of the part. It is something.

(Function) According to the present invention, since it is configured as described above,
The package is installed between the upper and lower flanges of the watertight container, and its vertical position is determined. The package can be firmly and easily fixed by positioning and holding down the package and sandwiching the package.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a package mounting device showing an embodiment of the present invention, and FIG. 2 is a top sectional view of the package mounting device.

As shown in these figures, the watertight container of the marine sensor has a lower flange 12 and an upper flange 1.
3. It consists of case 14, and although it is not shown in the figure, O
Each is fitted and joined using a sealing material such as a ring, and the package 11 is connected to the lower flange 12.
Although not shown in the figure, the upper flange 13 is inserted into the guide groove (same as the guide groove 12a) and positioned, and the bottom surfaces of the lower flange 12 and the upper flange 13 are aligned in the vertical direction. It can be suppressed by The center portion of the package 11 is clamped and fixed by a clamping portion 15a of a pad 15 made of styrofoam.

Next, the method of fixing the package using this device will be explained. The package 11 is held down in the vertical direction by the bottom surfaces of the lower flange 12 and the upper flange 13. In the direction perpendicular to the surface of the package 11, the guide grooves of the upper flange 12 and the lower flange 13 position and restrain the package. Furthermore, the central part of the package 11 is fixed between parts 15 to prevent vibrations, shakes due to shocks, and resonances applied to the ocean sensor. This part 15 is made of styrofoam,
Its outer shape is such that a part of it contacts the inner surface of the case 14 with elastic force at multiple points. Contact portions 15b, 15c, and 15d are formed that contact the inner surface of 14.
The external dimensions of these abutting parts 15b, 15c, and 15d are larger than the inner diameter of the case 14, and when they are inserted into the case 14, they shrink due to the force of insertion within the elasticity of the polystyrene foam, and the case 14
The dimensions match the inner diameter of the In addition, Pattu 15
There is a clamping part 15 that matches the shape of the package cage 11.
a, which directly contacts the package 11 and clamps the package 11 with the clamping portion 15a by elastic force due to contraction during insertion. in this way,
The shape of the pad 15 reliably and firmly fixes the package 11. Furthermore, since the parts are made of styrofoam, they are light, and even if subjected to vibration or impact, they will not shake because of their small mass and will not cause damage to the package cage 11. It goes without saying that the Styrofoam material can serve the purpose of any light foam material.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the invention) As explained in detail below, according to the invention, the central part of the package cage is held down with a styrofoam pad, so long package cages can be easily fixed to vibrations without using fastening parts such as screws. It is now possible to securely secure the product to withstand shock. Moreover,
Since screws and the like are not used, there is no need for a pedestal for a screw, a prepared hole, or a screw processing, and the cost of parts can be reduced. Furthermore, installation and removal during assembly and maintenance become easier, and assembly costs can be significantly reduced.
