Abstract
The invention discloses an elastic sheet used on a fire hazard detector, which is characterized in that the elastic sheet comprises a U-shaped elastic sheet body, wherein the side part of the elastic sheet body is pairwise provided with symmetrical first connecting parts, the bottom of the elastic sheet body is provided with third connecting parts which bend and extend towards the outside, second connecting parts which bend and extend towards the inside are arranged at any side part of the elastic sheet body, and the third connecting parts are provided with saw tooth-shaped tin coating layer end parts embedded into a circuit board. The third connecting parts arranged on the fire hazard detector of the invention are provided with the saw tooth-shaped end parts which can be made into sharp tip angles for ensuring to be pierced into the tin coating layer of contacts of the circuit board, and the reliable electricity supply can be realized. Because the elastic sheet is connected with the circuit board and circuits through the first connecting parts, the second connecting parts and the third connecting parts, a contact connection or insertion connection mode is adopted, the assembly technology is simplified, the welding is avoided, the work efficiency is improved, at the same time, the dismounting and the installation of the circuit board are convenient, and the maintenance is convenient.
Description
Technical field
The present invention 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 through 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.
Summary of the invention
In view of this, the technical problem that the present invention will solve is to provide a kind of shell fragment that is used on the fire detector, and this shell fragment is supplied power to wiring board through 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; Technical scheme of the present invention is achieved in that a kind of shell fragment; It comprises U-shaped shell fragment main body, and the sidepiece of said shell fragment main body is provided with the first paired and symmetrical connecting portion, and the bottom of said shell fragment main body is provided with the 3rd connecting portion of outwardly-bent extension; And curve inwardly to extend at the sidepiece of said arbitrary shell fragment main body and be provided with second connecting portion, said the 3rd connecting portion is provided with the zigzag end that is coated with the tin layer that embeds wiring board.
Said first connecting portion is square.
Said second connecting portion is a crotch shape.
The zigzag end of said the 3rd connecting portion is two.
The technique effect that the present invention reaches is following: the 3rd connecting portion on the fire detector of the present invention 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 through 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 present invention is used for the 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, and the 3rd 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 731.And curve inwardly to extend at the sidepiece of arbitrary shell fragment main body 74 and be provided with second connecting portion 72, in the present embodiment, second connecting portion 72 is a crotch shape, the zigzag end 731 of the 3rd connecting portion is two.
As shown in Figure 2, in the fire detector cutaway view, can find out the mounted configuration figure of shell fragment 7, 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 zigzag end 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 supply power to wiring board.Because shell fragment 7 embeds interfaces with wiring board 5, and wiring board 5 dismantle easily, is convenient to keep in repair.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
Claims (4)
1. shell fragment that is used on the fire detector; It is characterized in that; It comprises U-shaped shell fragment main body; The sidepiece of said shell fragment main body is provided with and first connecting portion of symmetry in pairs, and said first connecting portion is connected in the middle buckle structure of detector, in buckle and offer the slot that adapts with the first connecting portion shape and structure; The bottom of said shell fragment main body is provided with the 3rd connecting portion of outwardly-bent extension, and curves inwardly to extend at the sidepiece of said shell fragment main body and be provided with second connecting portion, and said second connecting portion touches conducting mutually with binding post, and binding post connects power line again; Said the 3rd connecting portion is provided with the zigzag end that is coated with the tin layer that embeds wiring board, and the sawtooth of said the 3rd connecting portion embeds being coated with in the tin layer of wiring board, thereby makes power line, binding post, shell fragment, wiring board form path, can supply power to wiring board.
