(1) A coil spring 9 that presses the terminal shaft 1 against the terminal plate of the device body, a guide plate 4 (horizontal lip) that holds the terminal shaft 1 movably up and down, the terminal shaft 1 and the lead wire 7
The lug plate 6 that connects the lug plate 6 and the solder connection between the lug plate 6 and the lead wire 7 are configured to form a straight line in the vertical direction, and these parts are connected to the battery case. In order to store the battery inside the battery case, it was necessary to increase the thickness of the entire battery case 2. In addition, since the bottom panel 10 of the battery case 2 is often formed of a metal plate, when the lug plate 6 to which the lead wire 7 is soldered is pushed downward, this lug plate 6
There is a possibility that the bottom panel 1o may come into contact with the bottom panel 1o, and some may come into contact with each other depending on the size variation. Therefore, in order to prevent this, an insulating sheet 11 had to be attached to the inner surface of the bottom panel. As a result, many dimensions had to be allocated in the above-mentioned vertical direction, resulting in an increase in the thickness of the battery case.

(a) Also, since the terminal shaft 1 must be fitted into the horizontal lip 4 of the cabinet 3, in the case of a battery case 2 that requires two or three terminal shafts 1, when assembling the battery case 2, This requires a large amount of man-hours, and it is necessary to assemble the terminal shaft 1 together with the battery to be assembled into the battery case 2, which is a complicated work.

The parts that make up the connection terminal are also included in the song.
There is a coil spring (not shown) that holds the bushing 5 facing upward, and these must be assembled when inserting the top cover 12 into the battery case 2, so the detailed assembly work can be done in the battery case. There was the complexity of having to do this during the blood-staining process.

The present invention aims to solve these problems and realize a structure that reduces dimensions, and also to eliminate the need to assemble connection terminals at the same time during the final process of assembling the battery into the battery case. It is something to do.

It was placed in the opening. Furthermore, the recesses provided on both sides of the connection terminal are engaged with two protrusions of the cabinet provided corresponding to the recesses, and the tip of the connection terminal is movably engaged with the opening inscribed in the opening. This is a terminal mounting structure.

Function: Since the connecting terminal according to the present invention is integrated into a single unit, the individual parts constituting the connecting terminal do not have to be assembled when the battery is assembled, and the connecting terminal can be installed by simply mounting the connecting terminal in a predetermined position. The tip of the bushing of the connection terminal is movably fitted into the opening provided in the top cover, the bottom part is placed against the inner surface of the bottom panel, and the top surface is held between the inner surface of the top cover to easily hold the connection terminal. It is something that can be done.
