Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.In the case where not conflicting, the feature in following embodiment and embodiment can be mutually combined.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.
It should be noted that in the utility model, when a component is considered as with another component " being connected ", it
Can be joined directly together with another component or be indirectly connected by component placed in the middle and another component.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model
The implication that the technical staff in domain is generally understood that is identical.It is simply in term used in the description of the present utility model herein
The purpose of description specific embodiment, rather than be intended to limit the utility model.
As shown in figure 1, the preferred embodiment of the utility model provides a kind of piezoelectric cable sensor 100, the piezoelectric electro
Cable sensor 100 is used to monitor human life signal, and by a shielded cable 200 by the induced signal monitored transmit to
One signal processing module 300（Such as a circuit board）Carry out follow-up signal transacting.
Such as Fig. 2, the piezoelectric cable sensor 100 includes an induction cable 10 and a shell 20.
In one embodiment, the induction cable 10 to an external force effect under produce an induced signal, the shell
20 are used to increase the lifting surface area of the induction cable 10 to improve the intensity of the induced signal of the induction cable 10.
Wherein, the length direction of shell 20 described in the interior edge of shell 20 is provided with an at least manhole 22, to pass through
State manhole 22 and coat the induction cable 10.The length direction of shell 20 is additionally provided with least one described in the interior edge of shell 20
Rhombus through hole 24, the side of each manhole 22 are equipped with the rhombus through hole 24.
When using the piezoelectric cable sensor 100, the rhombus through hole 24 in the shell 20 is in blank state.
In one embodiment, 2 manholes 22 and 4 rhombus through holes 24, described two circles are provided with the shell 20
Shape through hole 22 is disposed adjacent, and the both sides of described two manholes 22 are respectively equipped with two rhombus through holes 24.
In one embodiment, the manhole 22 and the rhombus through hole 24 are linearly arranged on same level direction
Cloth.
