In the conventional terminal structure, the cover-side terminal is housed in a housing cylinder, and one end of the cover-side terminal is connected to a circuit board provided in the cover device. An energizing terminal is inserted into the other end of the cover-side terminal and is electrically connected.

[0005] However, in the conventional example, the cover-side terminal is only accommodated in the accommodating cylinder, and there is no particular support. For this reason, when inserting an energizing terminal into the cover side terminal, the insertion load of the energizing terminal is supported at a place where the cover side terminal and the circuit board are connected. As a result, the cover side terminal and the circuit There is a possibility that connection failure with the substrate may occur.

The present invention has been devised in view of the above-mentioned conventional circumstances, and has as its object to provide a terminal structure capable of preventing a connection failure between a cover-side terminal and a circuit board from occurring.

Is provided in a direction in which the current-carrying terminal is inserted, and the cover-side terminal is locked to the housing cylinder by the terminal stopper and the spring.

According to a second aspect of the present invention, in the configuration of the first aspect, the terminal stopper and the spring are formed integrally with the cover-side terminal.

In such a configuration, the cover-side terminal is housed in a housing cylinder formed in the cover device, and one end of the cover-side terminal is connected to a circuit board provided in the cover device. In this case, the cover-side terminal is inserted into the housing cylinder, and is locked to the housing cylinder by the terminal stopper and the spring. At this time, the relative position between the cover-side terminal and the housing cylinder is adjusted by bending of the spring, and the terminal stopper correctly positions the cover-side terminal. by this,
The cover-side terminal is locked to the housing cylinder by a terminal stopper and a spring.

[0010] One end of the cover-side terminal is connected to a circuit board in a state where the cover-side terminal is locked in the housing cylinder. Note that solder is used to connect the cover-side terminal to the circuit board.

The cover-side terminal is housed in a housing cylinder,
With one end of the cover side terminal connected to the circuit board,
A current-carrying terminal is inserted into the other end of the cover-side terminal, so that the cover-side terminal and the current-carrying terminal are electrically connected.

At this time, the cover-side terminal is locked to the housing cylinder by a terminal stopper and a spring, and the insertion load of the energizing terminal is supported by the terminal stopper. It does not act on the connection with the substrate. For this reason, it is advantageously possible to prevent a connection failure between the cover-side terminal and the circuit board.

Therefore, a terminal structure capable of preventing a connection failure between the cover-side terminal and the circuit board can be obtained.

According to the second aspect of the present invention, since the terminal stopper and the spring are formed integrally with the cover-side terminal, the number of parts does not increase.
