On the other hand, as shown in FIGS. 1 and 2, inside the box-shaped body 1a, there are provided four storage portions 7a to 7d which are partitioned by a side wall, a partition wall 5 and a partition wall 6. Among them, the first and second storage portions 7 on both sides separated by the isolation wall 5 provided upright along the longitudinal direction of the body 1a.
a and 7b respectively have a ground side blade receiving spring block 10,
The locking springs 40, 40 and the release button 41, the voltage side blade receiving spring block 20, the locking spring 40 and the release button 41 are housed. Here, by forming a part of the center of both side surfaces along the longitudinal direction of the body 1a to bulge outward, it is formed to be wider than the other parts of the first and second storage parts 7a, 7b. The ground side terminal plate 12, the locking spring 40 and the release button 41, the voltage side terminal plate 22, the locking spring 40 and the release button 41 are housed in the wide portion. As described above, since the housing portion for housing the lock springs 40, 40 and the release button 41 is formed by bulging a part of the body 1a in the width direction, the body 1a and the housing 1 can be downsized. There is an advantage that space can be saved.
In addition, the opening surface of this wide portion is closed by the projecting pieces 8 which are projected outward from the substantially central portions of both side surfaces of the cover 1b.
