Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a housing used for communal television reception, etc., which houses an electronic circuit having functions necessary for communal television reception, mainly an amplification function, 1 branching, distribution, and mixing functions. The present invention relates to a mounting device for a casing.

BACKGROUND OF THE INVENTION Currently, a TV community reception casing is used in a state where it is fixed to the top of a pillar installed on the ground or on the roof of a house with screws parallel to the pillar.

Problems to be Solved by the Invention However, with the above-mentioned conventional configuration, if the support is tilted due to wind and rain, etc., and the fixed casing is tilted accordingly, rainwater etc. will enter through the joint between the casing and its sliding lid. There is.

Means for Solving the Problem Therefore, in the present invention, in order to install the mounting state on the support obliquely at an angle that will prevent rainwater from entering even if the support is tilted, the end face of the mounting part on the back side of the housing is made into an inclined surface. This is what I did.

Effect: The above configuration makes it possible to prevent rainwater and the like from entering the inside of the housing.

Embodiment Hereinafter, a case mounting device according to an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 are diagrams showing the configuration of a mounting device for mounting an amplifier for common television reception on a support pole, showing an embodiment of the present invention.

The housing 1 of this amplifier for common television reception is made of plastic material, and inside it there is a transmission line 3 from the antenna.
It has an electronic circuit that amplifies the signal sent through the transmission line 3 and sends the amplified signal to a television receiver or the like through another transmission line 3. This housing 1 consists of a case body part 1a and a lid part 1b. On the bottom surface of the case body part 1a, one end is connected to an internal electronic circuit, and the other end is connected to a plurality of transmission channels connected to an antenna, a television receiver, etc. A hole IC is provided through which the wire 3 passes. The number of holes IC can be changed as required. The support 2 to which the housing 1 is attached is usually a metal pipe, installed on the ground or on the roof of a house, and has an antenna attached to its upper end.

Now, in Figures 1 to 4, 4 is the case body 1a.
A mounting part 5 is integrally molded on the outer surface of the support column 2, and 5 is a 7-shaped abutting part with a contact surface 6 for the support column 2. The thickness of each wall is adjusted to be lower in the direction. 7
is a groove provided with a rib 9 for temporarily fixing a U-shaped tightening bolt 8 in the mounting part 4, and there is an entrance to the groove toward the bottom of the housing, from which the tightening bolt 8 is inserted, and the rib 9 is used to temporarily fix the tightening bolt 8. stop it.

On the outer surface of the mounting part 3 there is a rib 10.11 formed integrally with the mounting part 4, which prevents the tightening bolt 8 from falling down when the housing 1 is installed on the support column 2. Reference numeral 12 denotes a presser metal fitting provided opposite to the mounting portion 4, which is formed by bending a metal plate, and includes a U-shaped abutment portion 13 that is in contact with the support column 2, and collar portions 14 provided on both sides of the U-shaped abutment portion 13. It consists of 15. Reference numeral 16 designates a hole through which the tightening bolt 8 provided on the collar portion 14 passes, and reference numeral 17 indicates a notch formed in the collar portion 15 into which the tightening bolt 8 is inserted.

In addition, 18.19 is a threaded portion 20 of the tightening bolt 8.
．． The wing nut screwed onto 21 is shown.

The operation of the television communal reception amplifier housing mounting device configured as described above will be described below.

First, to temporarily tighten the housing 1 to which the transmission line 3 is attached, raise the bolt 8, place the support 2 against the figure 7-shaped contact part 5 of the mounting part 4, and rotate the presser metal fitting 12 to make the cut. 1
7 to insert the threaded portion 21 of the tightening bolt 8. In this state, tighten the wing nuts 18 and 19, and
The support 2 is sandwiched and fixed between the letter-shaped abutment part 5 and the U-shaped abutment part 13 of the presser metal fitting 12. At this time, the tightening bolt 8 tends to become perpendicular to the column 2. When the tightening bolt 8 becomes perpendicular to the support 2, the housing 1 also becomes perpendicular, making it impossible to mount it diagonally. Therefore, the rib 1 formed on the outer surface of the mounting part 3
1, the tightening bolt 8 is raised diagonally and the tightening bolt 8 is prevented from becoming perpendicular to the column 2. Further, as described above, the mounting portion 4 is made higher in the lower direction and lower in the upper direction, thereby making it possible to attach the housing 1 to the support column 2 diagonally.

Note that the angle P of the housing 1 with respect to the support column 2 is 10 degrees at maximum. If you tilt it any further, you will have to route the transmission line 3.
Furthermore, rainwater or the like is transmitted through the transmission line 3 and enters the inside of the casing 1 through the seam 22.

Effects of the Invention According to the present invention, even if the support column to which the casing is attached is tilted in a predetermined direction, the seam between the case body and the lid does not face upward, which prevents rainwater and the like from entering. Therefore, the life of the internal electronic circuit is extended and performance deterioration is prevented.Also,
When the support is installed vertically on the ground or on the roof of a house, it is attached diagonally to the support with the lower part of the casing protruding toward you, which has the effect of making it easier to operate the internal electronic circuit.
