Claims4
A triple sealing device for an electronics housing of smart instrumentation, the triple sealing device comprising:
- an electronic board;
- a first housing which has the electronic board disposed therein and comprises a first inlet port on a top wall to allow a cable to pass therethrough;
- a bottom wall of a second housing which is provided above the first inlet port of the first housing and coupled to the top wall of the first housing, and comprises a second inlet port to allow the cable to pass therethrough;
- an elastic block provided on an inner circumferential surface of the second inlet port;
- a cable which is connected to the electronic board and extends outward after passing through the first inlet port and the second inlet port, and
- a cable gland which comprises a hole to allow the cable to pass therethrough and is inserted into the first inlet port,
- wherein the second housing comprises a filler injection hole to allow a filler to be injected into the second housing,
- wherein the cable is connected to the electronic board, and the inside of the second housing is filled with the filler after the cable extends outward through the second inlet port,
- wherein the filler is blended with liquid and injected into the second housing, and the filler is coagulated inside the second housing, further comprising a filler injection hole cap configured to close the filler injection hole after the second housing is filled with the filler,
- wherein the second housing comprises a plurality of separable and assemblable body portions, and
- wherein the second housing is separably coupled to the first housing.
