DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a repeater used in a fire alarm system to a repeater panel or the like.

[0002]

2. Description of the Related Art A fire alarm system is usually mounted on a ceiling or the like and monitors the occurrence of a fire. When a fire occurs, a fire signal is received from the fire sensor to notify the occurrence of the fire. It is composed of a fire receiver, a district sound device that is provided for each district and notifies the occurrence of a fire by sounding, and a smoke exhaust device that discharges smoke to the outside.

[0003] The fire alarm system described above includes:
Further, a repeater is provided, and this repeater is exposed from the case and is provided with a signal line and a power supply line (hereinafter, referred to as an electric wire) from the fire receiver as shown in Japanese Utility Model Laid-Open No. 2-126299. A primary terminal group to be connected, a secondary terminal group to which wires from terminal devices such as fire detectors and smoke exhaust devices are connected, and a signal processing unit that is housed in a case and processes signals from these are provided. It is installed between a fire receiver and a fire detector, district sound equipment, smoke exhaust equipment, etc., and relays the exchange of signals between them. The address can be set by a switch or the like. When installing the repeater at a site or the like, usually, a plurality of repeaters are collectively mounted in a housing called a repeater panel, and the repeater panel is mounted on a wall surface or the like.

[0004]

In the repeater constructed as described above, when the cover is attached to the case, the cover is fixed to the holding plate and the secondary terminal group with screws, so that many screws are required. As a result, the cost increases, and attaching and detaching the cover is troublesome and takes a lot of time. Further, since the electric wires are connected to the secondary terminal group by screws, not only the connection takes time but also there is a risk of erroneous wiring.

Further, since the repeater itself is mounted on a repeater panel or the like with four screws, it is very troublesome to attach and detach a large number of repeaters. Further, since the primary terminal group and the secondary terminal group are provided close to each other, there are various problems such as erroneous wiring easily occurring, and furthermore, it is difficult for the wires to be entangled and hardly connected at the time of connection.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is easy to manufacture a repeater, attach it to a repeater panel or the like, and connect wires to a terminal group. The purpose is to obtain a mounting structure for a repeater of equipment.

It is assumed that an electric circuit is formed on the printed circuit board 30, and connectors 31a and 31b, a terminal block 32, and the like are attached. (1) The printed circuit board 30 is inserted into the case body 10 from the opening on the rear surface side of the case body 10, and the printed board insertion portions 26 a are provided at both front corners of the front end of the case body 10. , 26b, and the printed circuit board 30 is mounted on the mounting table 23. (2) Next, the screw insertion holes 34a,
34b is aligned with the screw holes 24a and 24b of the case body 10, the screws 35a and 35b are inserted and screwed in, and the printed circuit board 30 is fixed to the case body 10.

(3) Next, the fitting pieces 43a of the cover 40,
43b is fitted into the fitting portions 18a, 18b of the case body 10, and the rear surface side is pressed down. As a result, the locking pieces 47a and 47b provided on the cover 40 are lowered, and the locking claws 48 are provided.
a, 48b are engaged with the engaging portions 16a, 16b of the case body 10, the fitting portions 46a, 46b are fitted with the projections 15a, 15b of the case body 10, and the cover 40 is integrated with the case body 10. Are combined. At this time, the connectors 31a and 31b are inserted into the notches 41 of the cover 40.
In addition, the terminal block 32 is located in the notch 44,
The rotary dip switch 33 is located in the display window 49.

When disassembling the repeater for maintenance, inspection, etc., first, the notch 17 formed in the case body 10 is used.
a and 17b are rotated by inserting a flathead screwdriver or the like.
As a result, the rear surface of the cover 40 rises to
The cover 40 can be easily removed from the case body 10 by lifting the rear surface of the cover 40 and pulling the cover 40 rearward because the a and b are disengaged from the locking portions 16a and 16b. Thereafter, if it is detached in the reverse order of assembling, it is disassembled into the state of FIG.

In the repeater configured as described above,
To attach the printed circuit board 30 to the case body 10, one end of the printed circuit board 30 is inserted into the printed circuit board insertion portions 26a, 26b provided on the case body 10, and the other side is screwed.
Since it is only fixed at 5a and 35b, the number of screws can be reduced, and furthermore, the mounting is easy and the mounting time can be shortened. The cover 40 also has fitting portions 43a and 43b provided at one end thereof, and a fitting portion 18 provided at the case main body 10.
a, 18b, the other end is pressed down, and the locking claws 48a, 4
8b is engaged with the engaging portions 16a and 16b of the case main body 1 so as to be connected by one-touch, so that no screw is required, the operation is simple, and the fixing can be securely performed.

Further, a large number of electric wires of the fire receiver and terminal equipment are connected to the repeater, and the terminals to which these electric wires are connected are a front side (primary terminal group) and a rear side (secondary side). Terminal group), for example, two mounting arms 19
a, the terminal of the fire receiver is connected to the terminal provided with 19b (primary terminal group), and the wire of the terminal device is connected to the terminal provided with one mounting arm 21 (secondary terminal group). By connecting, there is no possibility of erroneous wiring, the wires can be securely connected, and the wires do not get entangled. Further, since the plug-in type terminal block is used, the attachment / detachment of the electric wire is extremely easy, and the attachment / detachment time can be greatly reduced.

Since the number of electric wires connected to the secondary terminal group varies depending on the number and types of terminal equipment to be connected, the desired number of terminal blocks 3 can be easily changed as described above.
2 are used. On the other hand, the number of electric wires of the fire receiver connected to the primary terminal group is basically determined (four in the embodiment). Usually, a plurality of such repeaters are installed collectively, and the electric wires from the fire receiver are connected so as to be feed wirings. Therefore, if the connector type terminal blocks 31a and 31b are used for the primary terminal group, the connection work can be easily performed.

Next, the rail 8 will be described. FIG. 4 is a perspective view showing a main part of the repeater panel 1, 2 is a housing, and 5 is a bottom plate thereof. Reference numeral 8 denotes a rail, and a main body 81 having a substantially U-shaped section
