Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a terminal board unit for a receiver that is installed in a receiver housing of a fire alarm system or the like and connects an outside line and an extension line.

[Prior Art] Conventionally, in the case of receivers for fire alarm equipment, etc., as shown in, for example, Japanese Utility Model Application No. 59-11389, etc.
A plurality of terminal board units are installed inside the housing, each equipped with a terminal board for connecting external lines and a printed circuit board for mounting circuit components and connecting internal lines, to increase the packaging density within the receiver housing and to facilitate wiring work for external lines and internal lines. We make it possible to do this efficiently.

By the way, there are two types of receivers for fire alarm equipment: a wall-mounted receiver 10 shown in FIG. 7 and a self-supporting receiver 12 shown in FIG. 8, and each has a different installation scale and environment.

That is, the wall-mounted receiver 10 is relatively small-scale and requires a small installation environment such as a manager's room, and as a result, a thin receiver is required. On the other hand, the stand-alone receiver 12 is intended for large-scale equipment, has a large installation environment such as a disaster prevention center, and is required to simply increase the packaging density rather than being thin.

[Problems to be solved by the invention] However, since the requirements of a wall-mounted receiver and a free-standing receiver are different for conventional terminal board units, it is necessary to create a dedicated terminal board unit that meets the requirements of the receiver. Since the terminal board units are prepared individually, there are problems in terms of parts management and productivity because two types of terminal board units are required, and there is also a problem in terms of cost.

The present invention was devised in view of these conventional problems, and aims to provide a terminal board unit for a receiver that can commonly meet the different demands of thinning and increasing packaging density.

[Means for Solving the Problem] First, the present invention is installed inside the casing of a receiver of fire alarm equipment, etc., and is equipped with a terminal board for connecting external wires and a printed circuit board for mounting electric components and for connecting internal wires. The target is the terminal board unit of the receiver.

As described above, the terminal board unit of the receiver according to the present invention has a book-shaped unit main body having at least two sides, a back surface and a side surface, and the terminal board and the printed circuit board on the back surface and the side surface of the unit main body. Mounting holes for mounting with screws are provided in the housing at positions that do not interfere with the mounting of the terminal card, and a terminal card pasting stand to be mounted on the terminal board is movable so as to face the front or side of the unit body. be.

[Function] The terminal board unit of the receiver according to the present invention having such a configuration is adapted to both wall-mounted receivers that require a thin profile and free-standing receivers that require high packaging density. The direction of the book-shaped unit body can be changed and installed using screws, and the same terminal board unit can be used for both the wall-mounted type and the free-standing type.

Additionally, the orientation of the unit changes between the wall-mounted type and the free-standing type, and as a result, the orientation of the terminal card affixing stand provided on the terminal board also changes, making it difficult to see from the outside. Since it is movable so that it faces the front or side of the terminal, the direction of the terminal card attachment base can be adjusted depending on the installed state of the unit, and when connecting external wires to the terminal board, the correct position can be determined without error based on the terminal card display. You can connect an outside line to.
