How to make the car camera airtight?It is the first quality factor for cameras. So how to ensure the air tightness pass rate? You can use the air tightness tester of Hirays. The Hirays air tightness test is an emerging high-tech air tightness tester, which is very suitable for the air tightness test of cameras.

In order to do a good job in air tightness testing of the camera, we must first understand the structure of the camera and its sealing process.

• 1. The mainstream sealing methods for vehicle cameras are sealing rings, tightening screws, and ultrasonic welding. If the air tightness results are like this, it is not difficult to use Hirays' air tightness tester to detect it.

• 2. For air tightness testing of mainstream car cameras, the test pressure of IPX7 waterproof is theoretically simulated by the pressure of one meter of water depth, which is about 10kpa. However, the camera industry generally uses 60KPA pressure to test the air tightness of car cameras.

• 3. Camera leakage points, sealing rings, screw holes, wires (wires without waterproof function), and the glued parts of the wire and the housing.They are all places that require air tightness tester testing.

• 4. The camera test was ok and the result was that it was soaked in water. It may be that water penetrated through the wire.

• 5. How to test the air tightness if the camera does not have an inflation hole?Make a sealed mold similar in appearance to the camera, place the camera inside the mold, and inflate the mold.You can check it by connecting it to the air tightness tester of Hai Ruisi.

• 6. How long does a test last?It takes about 20 seconds to use the air tightness tester of Hai Ruisi.This is a very efficient air tightness test, and air tightness testers from many manufacturers may not be able to do it.

• 7. What is the testing method?Do you want to soak in water?Did you put it in water to pressurize it?, the air tightness tester uses the compressed air detection method, which has completely replaced the use of water immersion to detect the air tightness of the camera. This is a new air tightness detection technology, which is widely used in air tightness testing in various industries: such as mobile phone waterproof testing, wire air tightness testing, audio air tightness testing, connector air tightness and other testing fields.
