Problems solved by technology
Since the assembly of the insulating terminal and the terminal board must meet the technical indicators of sealing and insulation, it will cause many disadvantages such as difficult manufacturing, cumbersome installation, low production efficiency, and long manufacturing period. Every time a new machine is shipped, it is almost time to do an airtight test. Many hydrogen leakage points were found, and the terminal assembly had to be replaced repeatedly to meet the technical requirements, often failing to meet the delivery date
More importantly, when the hydrogen leakage of the unit reaches a certain concentration during operation, it is easy to explode, which brings hidden dangers to the life safety of users.
The original terminal structure, due to the narrow space, the wiring operation is extremely difficult

Embodiment
[0021] Such as figure 1 The present invention shown is a kind of electrical connector for the temperature signal of a steam turbine generator. The terminal board 4 is connected to the joint surface of the unit by bolts 8 and washers 9, and the socket 2 is closed by bolts 7 and washers 5 and 6. To the wiring board 4, seal it with an "O"-shaped sealing ring 3, insert the plug 1 into the socket 2, weld the other end of the socket 2 with several temperature signal wires 10 drawn from the unit, and the other end of the plug 1 The temperature signal line leads to the main control room for real-time monitoring of the temperature signal in the unit.

Description
technical field [0001] The invention relates to the technical field of sealed electrical connectors, in particular to an electrical connector for a temperature signal sealed wiring device of a steam turbine generator. Background technique [0002] Since the generator operates under the internal hydrogen pressure of 0.3-0.5Mpa, the original design structure opens 300-550 holes on the generator temperature signal wiring board, and installs on the wiring board with insulated wire posts equal to the holes. The temperature signal inside the generator leads out to monitor the operating condition of the generator. Since the assembly of the insulating terminal and the terminal board must meet the technical indicators of sealing and insulation, it will cause many disadvantages such as difficult manufacturing, cumbersome installation, low production efficiency, and long manufacturing period. Every time a new machine is shipped, it is almost time to do an airtight test. Many hydrogen ...
