Formed individually as terminals The resistance connection portions of the second and third terminal fittings are formed as pressure contact slit portions for pressure contact connection of the lead wire terminals of the resistance, and are connected to the resistors connected to the pressure contact slit portions. This is because the insulation cover is attached to prevent it from coming off.

[0011]

[Action]

 When the connection terminal portions of the first and second terminal fittings are arranged adjacent to each other to form the connector terminal portion, the mating connectors can be connected together.

Further, when each resistance connecting portion of the second and third terminal fittings is a pressure contact slit portion, each lead wire terminal of the resistance can be pressure contact connected without using solder.

Therefore, it is possible to efficiently perform any connection work.
