[0002] Electrical installation projects are an important part of engineering construction, and cable laying is an important part of electrical engineering construction. Generally, pipes will be pre-buried in the wall, and then the cables will pass through the pipes, which play a role in protecting the cables.

[0003] There is a large gap between the existing cable and the conduit, which is prone to leakage. Therefore, some people will set a layer of rubber plug between the conduit and the cable to prevent leakage. For example, the Chinese utility model patent with announcement number CN212114679U specifically discloses a cable conduit leakage plugging device.

[0004] However, when the above-mentioned cable pipe leak-proof device is actually used, people will find that the device is to first pass the cable through the pipe and then insert the rubber plug into the leak-proof plug at the end of the pipe. However, since the rubber plug itself is soft and elastic, it is difficult to insert the rubber plug into the leak-proof plug during actual installation, and it is difficult to squeeze the rubber plug to fit the cable, which greatly reduces its sealing effect.
