Description

The utility model relates to the field of alarm and can be used in addressable fire or fire alarm systems as a housing for accommodating various functional modules for addressing, monitoring, alerting and controlling actuators included in the system.

At present, addressable alarm systems are well known, which are most in demand among users, since they most fully meet the new regulatory requirements and are more effective in detecting controlled alarm situations. Such systems include dozens and even hundreds of addressing, monitoring, warning and control devices having a detachable case consisting of a base and a cover interconnected, inside which a circuit board with electronic elements and functionally necessary addressing, monitoring, warning and control modules are installed connected to power wires and an alarm loop.

However, the use for each type of device of a specially designed and manufactured case, different from other cases with various elements of communication between the base and the cover, with holes for the circuit board, which ensure that the circuit board is equipped with only a precisely defined size, increases the production cost of the cases, complicates the assembly and lengthens its time and makes it difficult to install at the facility even the minimum number of devices necessary to create a modern addressable alarm system and its hope Foot operation. It also prevents the timely modification of the system and reduces its reliability.

Known housing described in patent RU 142404 "the housing of the device for security systems" (published on 06.27.2014) IPC G08B 13/00, containing a base and a cover, detachably connected to each other by a pair of swivel joints on one side and mating a small locking protrusion with a reciprocal a recess on the opposite side of the housing, forming a complete volume. The base is box-shaped, with internal high mounting racks with stiffening ribs and low racks with holes for placing the circuit board with electronic elements and functional modules, with mounting holes for fixing on the mounting surface, cutouts for supplying power wires and an alarm cable. The cover is made in the form of a rectangular-shaped pallet with stiffening ribs and one large through rectangular hole with a front panel.

However, the above-described case is difficult to assemble, has a bulky base and an unreliable fixation of the cover, only a circuit board of strictly defined design documentation can be placed in it, while the high mounting racks of the base can easily be damaged when internal elements are installed in the case.

The housing described in patent RU 124513 “Housing for a fire alarm system” (published on January 27, 2013) IPC G08B 19/00, comprising a base and a cover detachably connected to each other as by pairing two locking latches and corresponding mating holes, and bolted, and forming the assembly volume to accommodate the circuit board with electronic elements and functional modules. The base is made in the form of a hollow quadrangular truncated pyramid with a bottom fixed on its upper base, stiffeners fixed by one of their lateral edges on the corresponding inner sections of the wall surface of the hollow quadrangular truncated pyramid, niches made on the corresponding sections of the inner surface of one of the side (upper) the surfaces of the side of the hollow quadrangular truncated pyramid and bounding mating holes for latches, a bolt hole the base with a cover on the lower side surfaces of the side of the hollow quadrangular truncated pyramid, as well as with internal mounting posts of various heights made on the bottom with holes for fixing the circuit board, additional nodes and blocks, upper and lower pair of mounting holes with external support protrusions for positioning the device when mounting on a mounting surface, cutouts for supplying power wires and an alarm loop. The lid is made in the form of a rectangular-shaped pallet with a front panel located in a through rectangular window, stiffeners and locking latches located on the inner side walls, as well as with a through hole on the corresponding section of the surface of the lower side of the cover for bolting it through the corresponding hole on basis.

However, such a structural implementation of the base complicates the assembly of the device. Many assembly steps are complex and long-term, as they include the mandatory use of bolted connections: when installing a circuit board, when mounting on the basis of additional nodes and blocks, when fixing the cover on the base. In addition, the size of the information display area on the front panel is strictly limited by the window and cannot be changed without an additional stage of design design, which increases the cost of the product and reduces the versatility of the housing, limiting the number of connected actuators or controlled zones of the fire or fire alarm system.

The inventors were faced with the task of creating a universal housing for accommodating various functional modules for addressing, monitoring, alerting and controlling the actuators of the alarm system, compact, inexpensive, technologically advanced in production, easy to assemble, convenient for installation and reliable in operation.

The problem is solved by the fact that the proposed housing, containing a base and a cover detachably connected to each other by pairing the locking latches and mating holes and forming an assembly volume for placement of the circuit board with electronic elements and functional modules. The base is made with internal low racks with holes for fixing the circuit board, upper and lower pair mounting holes for fixing the base, around which external support protrusions are formed for positioning on the mounting surface, and cutouts for supplying power wires and an alarm cable, and the cover is made with front panel and stiffeners on the inner side walls. New in the claimed case is that the base is made in the form of a rectangular plate, on the inner side of which at the corners perpendicularly made fixing latches and corresponding guiding stops, and on the periphery there is a support flange with installation locks for the circuit board, while on the front panel of the cover through holes are made for LEDs with internal flare restrictions, and the side surface of the cover is made with the corresponding locking latches of the base in response to versts in the form of slots and with protrusions for opening the housing located on its inner side.

The technical result of the claimed housing is to simplify the assembly.

The claimed technical result is achieved by the fact that the base is structurally made in the form of a thin rectangular plate, on the inside of which there are low racks with holes for fixing the circuit board, perpendicularly protruding locking latches and corresponding guide stops for smoothly fixing the cover are located at the corners, and around the periphery made a supporting collar with installation locks for the circuit board. The cover is made with through holes for the LEDs on the front panel, with internal protrusions to limit the illumination, with counter holes in the form of symmetrical slots in the side surface of the cover, corresponding to the locking latches of the base, and with protrusions for opening the housing on its inside. This arrangement of the locking latches and counter holes provides the ability to quickly and easily remove the cover from the base, which simplifies assembly / disassembly of the housing during installation at the facility, and also allows you to mount the housing next to the cable channel, which increases the choice of location options for the device in the claimed housing during installation in a specific room. The use in the base design for installing the circuit board of both low racks with holes and mounting locks allows you to quickly and reliably install various sizes of circuit boards on the basis, that is, the base is universal and does not need to be modified if you need to install a different size circuit board . Performing on the inner side of the side surface of the lid protrusions control the opening of the housing increases the reliability of the device. In addition, the implementation of the information display area on the front panel by means of LEDs mounted on the circuit board and placed in the through holes of the cover makes it easy to increase the number of actuators controlled by the device and / or protected areas (rooms), which extends the functionality of the case, and the through holes of the cover for the LEDs of the internal protrusions of the illumination restriction prevents the illumination of adjacent inactive LEDs from the switched on LED, which facilitates the visual ualny control and increases the reliability of the device.
