[0002] An encoder is a device that encodes signals (such as bitstreams) or data and converts them into signal forms that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk, and the latter is called a code scale.

Therefore, a waterproof housing is often provided to wrap it. The existing waterproof housing of the encoder is usually assembled by bolts. When the encoder needs to be disassembled and repaired, the waterproof housing needs to be disassembled. Moreover, the bolts are exposed outside for a long time, and it is time-consuming and laborious to disassemble them after oxidation, and it also adds additional disassembly steps, affecting the repair efficiency of the encoder and increasing the labor intensity of workers.
