It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0027] like Figures 1-9 The present invention provides a fire alarm controller housing structure, comprising a housing 1 and a circuit board 2. One end of the housing 1 is arrayed with windows 101. A mounting plate 3 is disposed within the housing 1, spaced apart from the end of the housing 1. A flange 301 is disposed on the surface of the mounting plate 3 facing the windows 101. The flange 301 extends along the array direction of the windows 101. One end of the circuit board 2 is plugged into the flange 301, and the other end of the circuit board 2 is embedded in the window 101.

[0028] Specifically, windows 101 are rectangular slots that mate with the ends of circuit board 2. Windows 101 are arranged in an array on the upper end panel of box body 1. Mounting plate 3 is positioned within box body 1, below windows 101. Its ends, extending along the sides of box body 1, are fixed to opposite sides of the interior of box body 1. Circuit board 2 is inserted into box body 1 along windows 101, where the end inserted into box body 1 engages with flange 301, securing circuit board 2.

[0029] Furthermore, guide grooves 102 are provided at opposite ends of the window 101, and a pair of guide grooves 102 are respectively fitted with two opposite edges of the circuit board 2. Inserting the circuit board 2 along the guide grooves 102 on both sides can prevent damage to the electronic components of the circuit board 2.

[0030] Furthermore, in order to facilitate the lead connection of the circuit board 2, a connection terminal 202 is provided at the other end of the circuit board 2, and the connection terminal 202 is located outside the window 101. The connection terminal 202 can realize the external connection of the circuit board 2.

[0031] Furthermore, in order to better fix the circuit board 2 , a mounting board slot 302 corresponding to each window 101 is arrayed on the flange 301 , and one end of the circuit board 2 is embedded in the mounting board slot 302 corresponding to the window 101 .

[0032] Specifically, in the present invention, a pair of flanges 301 are spaced apart on opposite sides of the mounting plate 3. Mounting plate slots 302 on the flanges 301 are spaced apart and opposite to each other. The two sides of the lower end of the circuit board 2 are respectively inserted into the corresponding mounting plate slots 302. The two sides of the upper end of the circuit board 2 are respectively embedded in the guide grooves 102.

[0033] As a preference, there can be one flange 301. When there is one flange 301, the flange 301 is arranged in the middle of the mounting plate 3, and the lower end of the circuit board 2 is plugged into the flange.

[0034] As a preferred embodiment, the number of flanges 301 can be three or more, and the multiple flanges 301 are arranged in parallel and spaced apart on the mounting plate 3. The number and arrangement of flanges 301 are selected appropriately according to actual needs to meet the installation requirements of circuit boards 2 of different specifications and sizes.

[0035] Furthermore, in order to achieve better insertion of the circuit board 2 and the mounting board slot 302, a notch 201 is provided at one end of the circuit board 2, and the notch 201 is embedded in the mounting board slot 302. The notch 201 and the mounting board slot 302 are plugged into each other to achieve limited installation of the circuit board 2.

[0036] Furthermore, in order to facilitate the insertion of the circuit board 2 into the mounting board slot 302 , chamfers are provided on both sides of the outer end of the mounting board slot 302 , and a pair of chamfers form a trumpet shape to facilitate the insertion of the lower end of the circuit board 2 .

[0037] Furthermore, in order to facilitate the fixation of the upper end of the circuit board 2 , a stop plate 4 is provided outside the window 101 , one side of the stop plate 4 is detachably connected to the box body 1 , and the other side of the stop plate 4 stops the other end of the circuit board 2 .

[0038] Specifically, one side of stop plate 4 is screwed to the surface of box body 1 on the side of window 101. At least one side of the upper end of circuit board 2 is located at the lower end of stop plate 4 and is blocked by stop plate 4. The other side of stop plate 4 is positioned opposite one side of terminal block 202. After circuit board 2 is inserted into box body 1, stop plate 4 is placed on window 101 and fixed to prevent circuit board 2 from moving out of window 101.

[0039] Preferably, a latch is provided on one side of the stop plate 4, and a slot is provided on the box body 1, with the latch and the slot being detachably connected. When fixing the stop plate 4, the latch is pressed into the slot. When removing the stop plate 4, the edge of the stop plate 4 at the latch end can be lifted with a flat-blade screwdriver or other tool.

[0040] Furthermore, in order to lighten the mounting plate 3, a strip-shaped slot 301 is provided on the mounting plate 3. This not only ensures the strength of the mounting plate 3, but also reduces the overall weight.

[0041] The present invention provides a fire alarm controller housing structure. During use, the lower end of the circuit board 2 is inserted into the flange 301 along the window 101. The upper end of the circuit board 2 is positioned within the window 101 and is substantially flush with the upper end of the window 101. The stop plate 4 is screwed to the housing body 1 on the side of the window 101. One side of the stop plate 4 abuts against the upper end of the circuit board 2. Finally, the external wiring of the circuit board 2 is connected. When the circuit board 2 needs to be removed or maintained, the housing body 1 does not need to be opened; the circuit board 2 can be removed by simply removing the stop plate 4.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
