Abstract
The utility model discloses a miniature vibration sensor, comprising a PCB board and a plurality of electronic elements arranged on the PCB board, wherein a plurality of electronic elements are SMD components. The miniature vibration sensor has the advantages of small volume, high resistance to bad environment, long service life and the like.
Description
Technical field
The utility model relates to the electric anti-thief device field of automobile, especially relates to the vibrating sensing apparatus of car alarm.
Background technology
Vibration transducer in the automotive electronics anti-theft device is owing to will be installed on the vehicle, and must adapt to environment such as vibration, high temperature, humidity, therefore require miniaturization, high-performance, long-life, used a large amount of hand plug-in resistances in traditional vibration transducer, the electrochemical capacitor equal-volume is big, the element of anti-adverse environment ability, can not reach miniaturization, high-performance, long-life requirement.
The utility model content
The purpose of this utility model is: provide that a kind of volume is little, strong, the long-life micro-vibration sensor of anti-adverse environment ability.
The purpose of this utility model is achieved in that
A kind of micro-vibration sensor comprises: a pcb board and some electronic components of being located on this pcb board is characterized in that: described some electronic components are surface mount elements.
Because surface mount elements takies less pcb board area, be convenient to the pcb board layout-design, it is little therefore to have a volume, and the ability of anti-adverse environment is stronger, longer service life.
As the improvement of technique scheme, further technical scheme of the present utility model is as follows:
Further, above-mentioned electronic component comprises resistance.
Further, above-mentioned electronic component comprises electric capacity.
Further, above-mentioned pcb board is a single sided board.
Further, above-mentioned pcb board is a dual platen.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
As shown in Figure 1, because prior art has adopted a large amount of hand plug-in units such as electrochemical capacitor, therefore, the area of pcb board is bigger.
As shown in Figure 2, present embodiment comprises: a pcb board 1 and some electronic components of being located on this pcb board 2, some electronic components 2 are surface mount elements.
Because surface mount elements takies less pcb board area, be convenient to the pcb board layout-design, it is little therefore to have a volume, and the ability of anti-adverse environment is stronger, longer service life.
The electronic component of present embodiment comprises resistance, electric capacity etc.
The pcb board of this enforcement can be a single sided board, also can be dual platen.
Be a kind of embodiment that provides in conjunction with particular content as mentioned above, can not assert that concrete enforcement of the present utility model is confined to these explanations.All approximate, identical with the utility model structure, device etc., or, all should be considered as protection domain of the present utility model for making some technology deduction or replace under the utility model design prerequisite.
