Description

[Detailed description of the invention] This invention relates to outdoor public listening equipment, and is applicable to CATV.
When wiring a power feed line from a receiving antenna to each television receiver, etc., a display means is provided to indicate whether or not equipment such as an amplifier connected between the feed lines is operating normally. It provides outdoor public listening equipment.

Generally, such outdoor public listening equipment is attached to a telephone wire stretched over a utility pole, and is located at a considerably high position above the ground, so it is necessary to check whether the outdoor public listening equipment is working properly. When doing this, workers had to climb up high pillars and open the lids of the equipment, making the work both difficult and dangerous.

For this reason, if outdoor public listening equipment is provided with display means that can be seen from the outside to indicate its operation, operation can be easily checked from the ground without having to climb the pole, and only the equipment that is displaying an abnormality can be placed on the pole. All you have to do is climb up and do the work, which greatly improves your work efficiency.

The present invention provides an outdoor public listening device equipped with an operation display means as described above, and the display means is of a waterproof type, so that the device is well protected from rainwater.

An example of an underground tree design will be described using drawings.

Referring to Fig. 1, 1 is the case body of the outdoor public listening equipment, which consists of a container 2 and a lid 3 that covers it, and is installed at a high place such as above a telephone pole, and inside is equipped with an amplifier circuit, a branch circuit, etc. It is sealed and watertight to prevent snow, rain, and moisture from penetrating inside.

FIG. 2 is an enlarged sectional view of FIG. 1, in which a through hole 4 is formed on the side surface of the lid 3 (or the container 2), and a step 5 provided in an annular shape around the outer circumference of the through hole 4 is used to maintain watertightness. An O-ring 6 made of rubber or the like is inserted, a transparent plate 7 is inserted into the front of the OIJ ring 6, and a hollow screw 8 for holding down the transparent plate 7 is screwed into the frontmost part. .

On the other hand, inside the lid 3, a lamp 10 is provided on a mounting bracket 9 in parallel with the through hole 4.

This lamp 10 is connected to a circuit within the case body 1 and is provided so as to be inspected only when this circuit is in normal operation.

Therefore, if this lamp 10 is off, it can be seen at a glance that the circuit is abnormal.

Note: The lamp 10 may be turned on only when the circuit is in an abnormal state.

7. As mentioned above, according to the present invention, the outdoor public listening equipment is equipped with a display means that can display the internal circuit operation. It is possible to easily determine whether a circuit is operating normally or abnormally just by looking at it from the ground, and it saves the trouble of climbing up a utility pole.

Moreover, since the display means is of a waterproof type, there is no risk of rainwater or the like intruding, and the internal circuitry can be safely protected.

Furthermore, in this invention, a lamp is provided inside the case, a through hole is provided in the case body, and the display is visible from the outside using an O-ring and a transparent plate. There is no need to remove the lamp and its wiring from the case body each time, greatly improving work efficiency.
