Being additionally provided with flange on the lateral wall of described conductor terminal spacing, flange is spacing to be divided into conductor terminal
Epimere and hypomere, the terminal cavities opening part of upper shell is provided with terminal sealing circle, and the hypomere sleeve of conductor terminal enters terminal
Intracavity, and flange is spacing offsets with terminal sealing circle, the hypomere of conductor terminal is fixed in terminal cavities by wire lid;And
And, owing to the terminal sealing circle of terminal cavities opening is arranged, make the grafting between the hypomere of conductor terminal and terminal cavities coordinate,
Ensure there is good water-stop effect.
The beneficial effects of the utility model are as follows:
(1) this kind of pressure transducer, is arranged to fast connection rod structure, convenient with outside quick union simply by water inlet
Realize quickly connecting, and operate simple, quick.
(2) further, pass through to set up the conductor terminal that can be disassembled, it is achieved pressure transducer carries wire connecting ends
Son, (external) that both facilitated user uses, and ensures again the accurate induction monitoring of pressure transducer, and, its simple in construction, conjunction
Reason;It addition, by setting up tapped wire lid, wire lid has wire through-hole, the most effectively wire is connected
Terminal is fixed in terminal cavities, can constitute good sealing knot by the sealing ring of its flange spacing mating terminals chamber opening again
Structure, it is ensured that terminal cavities has good water-stop effect.
(3) being provided with induction cavity sealing ring in being additionally, since the storage tank of lower house, pressure sensitive mechanism is arranged on upper casing
In the storage tank of body, also pressure sensitive answers chamber sealing ring, and the water being effectively prevented in lower house storage tank enters in pressure sensitive mechanism
The electric control gear in portion, the water-stop making electric control gear is more preferable.
Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of pressure transducer with fast connection rod structure, including housing 1, described housing 1 is arranged
