Description

[Detailed Description of the Invention] This invention relates to a terminal block in which a mark plate is stopped and fixed to the terminal block by using an end plate that closes an opening of the terminal block attached to the terminal end.

Usually, in a terminal block, a mark plate is inserted into a mark plate insertion groove opened on the top surface of the terminal block to display the terminal block. Conventionally, when installing this mark plate, the mark plate was cut in advance according to the connection length of the terminal block and then installed, which often resulted in variations in cut dimensions due to measurement errors, etc. For this reason, the mark plate may become longer or shorter than the predetermined length after being attached to the terminal block, resulting in an unsightly disadvantage.
In addition, after the mark plate is installed, it is necessary to fix the mark plate on the terminal block to prevent it from shifting or coming off due to vibrations, etc. For this purpose, it is necessary to attach the mark plate or install it separately. It was also complicated in terms of workability, as it required fixing with a fixed fixture.

This idea was developed in consideration of the above points, and uses the end plate used to close the opening of the terminal block to enable easy attachment and fixation of the mark plate. .

FIG. 1 shows a perspective view of the terminal block according to this invention, FIG. 2 shows a longitudinal sectional front view of the main parts of the terminal block according to this invention, and FIG. 3 shows an end plate used in this invention, FIG. 3A shows a front view, and FIG. 3B shows a rear view.

Reference numeral 1 denotes a single terminal block, which has a structure in which a separator 12 is erected on one side of an insulating stand 11, and a terminal 13 is held horizontally on the insulating stand 11. In addition, 1
4 is a mounting portion to the rail 2; An appropriate number of such terminal blocks 1 are sequentially connected in the same direction as necessary to form a connected terminal block as shown in FIG. 2. Each terminal block 1 is formed with a mark plate fitting groove 15 having an opening on its upper surface.
A mark plate 16 is fitted and disposed at 5. Reference numeral 3 denotes an end plate according to this invention. On its front side, as shown in FIG. A recess 34 that forms the stopper 32 and that can fit into the connecting projection 17 of the terminal block 1 is formed at a corresponding portion of the connecting projection 17 . Also on the back side there is a third
As shown in FIG. 2B, a substantially rectangular recess 35 is formed, and the end piece of the mark plate 16 is sandwiched between this recess 35 and the separator 12 of the terminal block 1. To install the mark board with something like this, first,
As shown in FIG. 2, the end plate 3
Fit the terminal block A with its front side facing the terminal block A.
After that, insert the mark plate 16 into the groove 15 at its tip 16.
While inserting the mark plate 16 to the position where it contacts the stopper 32 of the end plate 3, bend the other end 16b of the mark plate 16 along the separator 12 of the end terminal block B opposite to the terminal block A, and then Place the mark plate 1 with the back side of the end plate 3 facing the separator 12 of the terminal block B.
The other end 16b of 6 is clamped and attached between the separator 12 and the recess 35 of the end plate 3. Note that 4, 4 is a rail fixing device that is sandwiched between both ends of the connecting terminal block.

According to this invention, it is sufficient to cut the mark plate 16 in advance to a size that is slightly wider than the length of the connecting terminal block, so that the conventional drawbacks caused by variations in cut size can be eliminated. In addition, since the end portion 16b of the mark plate 16 is clamped and fixed between the terminal block and the end plate 3, there is no need to attach a mark plate, and there is no need to prepare a special fixing device. Since there is no need to do this, it has practical effects such as good workability and economy.
