Abstract
The utility model discloses a spring plate used on a fire detector, which is characterized by comprising a U-shaped spring plate main body, wherein the lateral part of the spring plate main body is provided with symmetrical first connecting parts in pairs; the bottom of the spring plate main body is provided with a second connecting part extending outwards in a bending mode; any one lateral part of the spring plate main body is bent inwards and extends to form a third connecting part; and the third connecting part is provided with a sawtooth-shaped end part embedded into a tin plating layer of a circuit board. The third connecting part on the fire detector of the utility model is provided with the sawtooth-shaped end part with sharper closed angle, so as to guarantee to be embedded into the tin plating layer of a contact point of the circuit board and reliably supply power the spring plate is connected between the circuit board and a circuit by the first, second and third connecting parts and adopts a touch or insertion mode so as to simplify the assembly process, be free from welding, improve the working efficiency and have the advantages of convenient assembly and disassembly of the circuit board and convenient maintenance.
Description
Technical field
The utility model relates to a kind of fire detector, especially the shell fragment on the fire detector.
Background technology
In existing fire detector, shell fragment is provided, and power supply has two kinds of connected modes usually to wiring board, and a kind of is welding manner; A kind of is by the screw fastening means, and this dual mode its technology when producing is all very complicated, if the product of producing in batches, production efficiency is very low, and the dismounting of wiring board is also inconvenient.
The utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of shell fragment that is used on the fire detector, and this shell fragment is powered to wiring board by the mode of pegging graft, and need not adopt the mode of welding, simplifies supply power mode.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of shell fragment that is used on the fire detector, it comprises U-shaped shell fragment main body, the sidepiece of described shell fragment main body is provided with the first paired and symmetrical connecting portion, the bottom of described shell fragment main body is provided with second connecting portion of outwardly-bent extension, and curve inwardly to extend at the sidepiece of described arbitrary shell fragment main body and be provided with the 3rd connecting portion, described the 3rd connecting portion is provided with the zigzag end that is coated with the tin layer that embeds wiring board.
Described first connecting portion is square.
The described second connecting portion crotch shape.
The sawtooth of described the 3rd connecting portion is two.
The technique effect that the utility model reaches is as follows: the 3rd connecting portion on the utility model fire detector is provided with zigzag end, wedge angle that can be sharper, and what can embed the wiring board contact point is coated with the tin layer, reliably power supply.Because shell fragment is connected by between first, second, third connecting portion and wiring board and the power supply, employing be the mode that touches or peg graft, packaging technology is simplified, and exempts to weld high efficiency.The wiring board easy accessibility is convenient to maintenance.

Fig. 2 is the cutaway view of fire detector.
Embodiment
As shown in Figure 1, for the utility model is used for shell fragment 7 on the fire detector 1, it comprises U-shaped shell fragment main body 74, the sidepiece of shell fragment main body 74 is provided with paired and symmetrical square first connecting portion 71, second connecting portion, 73, the three connecting portions 73 that the bottom of shell fragment main body 74 is provided with outwardly-bent extension are provided with zigzag end.And curve inwardly to extend at the sidepiece of arbitrary shell fragment main body 74 and be provided with the 3rd connecting portion 72, in the present embodiment, the sawtooth 731 of second connecting portion, 73 crotch shapes the 3rd connecting portion is two.
As shown in Figure 2, in the fire detector cutaway view, the mounted configuration figure of shell fragment 7 as can be seen, first connecting portion 71 is connected in middle button 6 structures of detector, offers the slot that adapts with first connecting portion, 7 shapes and structure (among the figure not view) on the middle button 6.Second connecting portion 72 touches conducting mutually with binding post 9, binding post 9 connects power line again, the sawtooth 731 of second connecting portion embeds being coated with in the tin layer of wiring board 5, thereby makes power line, binding post, shell fragment 7 and wiring board 5 just form path, can power to wiring board.Because shell fragment 7 and wiring board 5 embeds interfaces, and wiring board 5 dismantle easily, is convenient to keep in repair.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection range of the present utility model.
