Specific embodiment
The utility model is described in further detail below with reference to test example and specific embodiment.But it should not be by this
The range for being interpreted as the above-mentioned theme of the utility model is only limitted to embodiment below, all to be realized based on the content of the present invention
Technology belongs to the scope of the utility model.
As shown in Figure 1 to 4, the through-flow detection sensor structure of the utility model comprising upper housing 1,2 and of lower case
Detection unit 6.
Wherein, after upper housing 1 and lower case 2 are docked, form a seal cavity 10 in centre and respectively in right end and
Left end forms necking section 20 and necking section 30.Moreover, cable 40 is located at neck when cable 40 is clamped in necking section 20 and necking section 30
Being partially accommodated in seal cavity 10 between contracting portion 20 and necking section 30, and by detection unit 6 to one in seal cavity 10
Section cable is detected.
In the through-flow detection sensor structure of the utility model, waterproof connector 3 is provided in lower case 2, detection unit 6
