Abstract
The utility model discloses a trigger switch circuit board for a manual alarm device, which is applied to the manual alarm device and comprises a printed circuit board integrated with a trigger switchcircuit. At least two coating areas are arranged at the position close to the edge of the printed circuit board; the surface of each coating area is connected with a metal coating; the metal coatingof each coating area is in conducting communication with a corresponding circuit of the printed circuit board; a center hole for facilitating wiring and fixing penetrates through the printed circuit board and is disposed at the central position of each coating area. The trigger switch circuit board adopts the structure that the trigger switch circuit of the manual alarm device is integrated onto the printed circuit board, and the coating areas coated with the metal coatings are arranged on the circuit board; when in assembly, the printed circuit board is directly fixed onto a casing body of the manual alarm device, and an input/output conducting wire is fixed by employing the coating areas to match with screws; accordingly, the structure reduces the volume of circuit portions, simplifies installation, improves reliability, decreases the arrangement of wiring terminals and lowering cost.
Description
Technical field
The utility model relates to a kind of manual warning device, relates in particular to the trigger switch circuit in the manual warning device.
Background technology
Manually warning device is used for the fire alarm autoalarm of corridor and factory building more, and it generally includes the main body that is provided with push plate, has a breach on main body push plate is exposed, and is provided with the trigger switch circuit in main body; Just often, push plate is separated with the switch of trigger switch circuit, and circuit disconnects; When manually push plate being depressed, pressing plate is pushed down switch and is made the trigger switch circuit turn-on.Trigger switch circuit in the existing manual warning device is formed by connecting with lead by a plurality of electronic components usually, connects binding post at last, is connected by the input and the output lead of binding post with the outside again.The trigger switch circuit of this structure often needs to occupy big quantity space, thereby makes manual warning device overall volume bigger than normal, and the fixing/assembling of trigger switch circuit in manual warning device housing is cumbersome, occurs fault easily.
Summary of the invention
The utility model is in order to solve in the existing manual warning device, the bulky defective of trigger switch circuit, a kind of trigger switch circuit board that is used for manual warning device is provided, its at a printed circuit board upper set associated electronic components and binding post, not only dwindle volume, made things convenient for installation, improved the reliability of circuit simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of trigger switch circuit board that is used for manual warning device, comprise the printed circuit board (PCB) that is integrated with the trigger switch circuit, be provided with the coating district that at least two surfaces are connected with the coat of metal, the corresponding line conducting of the coat of metal in coating district and printed circuit board (PCB) by the printed circuit board edge place.Middle part, described coating district has the mesopore that penetrates printed circuit board (PCB) and makes things convenient for wiring, fixing.
Leave the slit between described per two adjacent coating districts.Prevent the electric circuit part short circuit that two coating districts connect.
Described coating district is the rectangular area on the printed circuit board (PCB), is equipped with the coat of metal in this regional front reverse side and mesopore.
In the housing of the manual warning device of fixed printed circuit board, have groove with corresponding position, coating district, the groove outside is embedded with nut, one penetrate mesopore screw cooperate with nut, and between screw and coating district, be provided with lead.Hence one can see that by with the cooperating of screw, the effect of splicing ear is promptly played in the coating district.
The utility model is by being integrated into printed circuit board (PCB) with the trigger switch circuit in the manual warning device, and the coating district be coated with the coat of metal is set on circuit board, printed circuit board (PCB) directly is fixed to manual warning device housing in the assembling, and fixes the I/O lead by coating district attachment screw; This structure makes the volume of circuit part reduce, install simplification, reliability improves, and has reduced the setting of binding post, reduces cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, a kind of trigger switch circuit board that is used for manual warning device, comprise the printed circuit board (PCB) 1 that is integrated with the trigger switch circuit, be provided with eight coating districts 3, the corresponding line conducting of the coat of metal in coating district 3 and printed circuit board (PCB) 1 by printed circuit board (PCB) 1 edge.Have the mesopore 2 that penetrates printed circuit board (PCB) 1 at 3 middle parts, coating district.Coating district 3 is the rectangular area on the printed circuit board (PCB) 1, is equipped with the coat of metal in this regional front reverse side and mesopore 2.Described eight coating districts 3 lay respectively at printed circuit board (PCB) 1 both sides, and close in twos, leave the slit between per two mutually close coating districts 3, with the electric circuit part short circuit that prevents that two coating, 3 districts from connecting.In the housing 5 of the manual warning device of fixed printed circuit board 1, have groove 6 with 3 corresponding positions, coating district, groove 6 outsides are embedded with nut 7, one penetrate mesopore 2 screw 9 cooperate with nut 7, and between screw 9 and coating district 3, be provided with lead 8, make the coat of metal circuit turn-on in lead 8 and coating district 3 by the screw 9 and the power that screws of nut 7.Hence one can see that by with the cooperating of screw 9, the effect that substitutes splicing ear is promptly played in coating district 3.
With reference to Fig. 1, according to actual needs, describedly be not limited to eight in coating district 3 quantity that are provided with by printed circuit board (PCB) 1 edge, also can be other suitable number.
Claims (4)
1, a kind of trigger switch circuit board that is used for manual warning device, comprise the printed circuit board (PCB) (1) that is integrated with the trigger switch circuit, it is characterized in that: be provided with the coating district (3) that at least two surfaces are connected with the coat of metal, the corresponding line conducting of the coat of metal of coating district (3) and printed circuit board (PCB) (1) by printed circuit board (PCB) (1) edge.
2, the trigger switch circuit board that is used for manual warning device according to claim 1 is characterized in that: middle part, described coating district (3) has the mesopore (2) that penetrates printed circuit board (PCB) (1).
