[0005]

According to the present invention, in a terminal device comprising a terminal block on which a plurality of terminals are arranged and a terminal cover for covering the exposed charging parts of these terminals, the terminal covers are provided on their side surfaces which are provided in the downward direction. A vertical pressing plate having a downward semi-arrowhead projection, a front-back pressing angular convex portion, and a horizontal pressing plate composed of plates provided on both sides of the terminal cover, for example, the terminal block, For example, it fits in the vertical fitting groove that fits in the semi-arrow-shaped projections of the vertical pressing plate provided on the inner walls that partition between the terminals arranged in parallel, and the angular convex portion in the front-back direction. A front-rear fitting groove and a left-right fitting portion that fits in the left and right holding plates, for example, a left-right fitting portion that separates both side surfaces of the plurality of terminals from the outside are provided. So
When the terminal cover is pushed in downward, the half arrow-shaped protrusions on the side surface of the vertical pressing plate move laterally due to the lateral bending of the vertical pressing plate, and then fall into the vertical fitting groove of the terminal block. To meet. At the same time, the front-rear direction pressing angular projection is fitted in the front-rear fitting groove, and the left-right pressing plate is fitted in the left-right fitting portion. In this way, the vertical, front-rear, and left-right three-directions are the half arrow-bottom protrusion and the vertical fitting groove of the vertical pressing plate, the longitudinal pressing angular convex portion and the front-back fitting groove, and the horizontal pressing plate, respectively. Since it is fixed by the left-right fitting portion, it is securely fixed.

When two terminals having different widths are arranged in parallel, the position of the inner wall partitioning the terminals deviates from the center line, and especially the arrangement order of these terminals is different. At this time, they are displaced from each other in opposite directions with respect to the center line, but in this case, one of the half arrowhead projections provided on both sides of the vertical pressing plate should fit in the vertical fitting groove provided on the inner wall. By doing so, the terminal covers having the same structure can be used regardless of the arrangement order of the terminals.

To remove the terminal cover, for example, the vertical pressing plate is bent with a screwdriver or the like, and the half arrowhead projection on the side surface is removed from the vertical fitting groove and pulled upward.
