Therefore, it is possible to prevent the inflow of external moisture, thereby ensuring stable performance even in a harsh environment To the connector assembly.

In recent years, various types of buildings such as high-rise buildings and underground commercial facilities have been developed in urban areas due to urban development and construction technology development. These buildings are equipped with various interior facilities for the convenience of living, and the danger to the fire is increasing because many people use them.

When a fire occurs in these buildings, the internal structure of the building is complicated and the scale of the building is so large that it is difficult for people to evacuate quickly and the fire suppression is also very difficult, which can greatly increase the fire damage.

Particularly, firefighters entering the building for fire suppression or rescue activities are also facing difficulties such as being in danger or being injured during the fire fighting process.

The threat to the safety of firefighters has recently become very socially appealing, and in recent years, various devices have been provided to enable firefighters to perform safety and device activities more efficiently.

For example, in the event of a disaster such as a fire, a rescue activity plan has been established in which a separate electronic communication equipment is installed inside the building so as to grasp the structure inside the building and grasp the location of firefighters.

In this case, a plurality of electronic communication equipments must be installed at the disaster site, which can be achieved by installing a plurality of electronic communication equipments inside the building in the process of entering the building. In this process, in order to connect a plurality of electronic communication equipments to each other, a connector is generally required. In the case of a general connector, there is a limit to use in a disaster environment.

That is, in a general disaster environment, it is difficult to secure the visibility because the power supply is cut off due to the power supply cut-off, and the installation environment is very poor such as exposure to water such as fire water. Is a very difficult situation.
