Description

[Detailed description of the invention] Industrial application field The present invention relates to a terminal block, and in particular to a terminal block formed by arranging a required number of terminal block units in series and sandwiching them from both sides with side blocks. Regarding improvements.

BACKGROUND OF THE INVENTION It would be very convenient if the type of wiring each terminal of a terminal block, which serves as a relay point for a large number of wiring lines, relates to is clearly indicated on the terminal block, since the wiring work can be done quickly and without errors.

Therefore, in the conventional terminal block, a cutout is formed on the upper side of the partition wall of each terminal block unit, a rectangular name plate is inserted into the cutout, and a description regarding each terminal is written on the name plate.

However, in the terminal block having the above structure, the name plate inserted into the notch can slide in the longitudinal direction of the terminal block, but cannot slide in the width direction of the terminal block. Therefore, when wiring or the like is to be applied to the relay terminal, it is necessary to perform the complicated work of once removing the name plate, wiring, and then reattaching the name plate after wiring.

On the other hand, if you want to make the name plate slidable in the width direction of the terminal block, for example, as in the invention described in Japanese Utility Model Publication No. 55-3656, it is necessary to have a plurality of terminal connection parts,
It has a terminal block main body with a partition wall between each connection part, a cover formed of an elastic material covering each of the terminals, and facing the partition walls located at both ends of the terminal block main body with a predetermined gap between the end faces of the main body. The end of the cover is inserted into the gap between the protrusion and the partition wall so that it can slide freely and be pressed against the partition wall by the protrusion, thereby locking the cover to the main body and attaching it to a part of the cover. There is a terminal block with a cover that is provided with a protrusion that comes into contact with the protrusion and restricts the amount of sliding of the cover.

Problems to be solved by the invention However, in the invention, the width of the cover is approximately equal to the width of the terminal block body. Therefore, when the cover is slid in the width direction, approximately half of the width of the cover protrudes outside the terminal block body. Such protrusion of the cover naturally limits the arrangement of components around the terminal block.

Yet another problem is that the overall structure of the device is very complex. For example, the locking means for the cover terminal block body is complicated and quite complicated. For example, taking the terminal block body as an example,
The shape of the partition wall and the protrusion (the structure of the entire protrusion) must be complicated, and sliding the name plate requires tools such as a screwdriver, as well as parts such as screws.

Therefore, the present invention eliminates the need for tools such as screwdrivers when sliding the name plate, which simplifies handling and reduces the number of parts such as screws. The purpose of this invention is to provide a terminal block that can completely prevent the name plate from protruding by improving the sliding of the plate so that it only slides within the width of the terminal block unit. There is.

Means for Solving the Problems The terminal block of this invention consists of a plurality of terminal block units, a side block that holds both sides of the connected terminal block units, and a side block cut into the inner surface of the side plate of the side block. The terminal block is equipped with a name plate having both ends slidably fitted into a horizontal groove, and the terminal block unit includes a relay terminal and a partition wall separating the relay terminal, and the horizontal groove of the side block is The partition wall has two horizontal surfaces and an inclined surface between the horizontal surfaces, and the upper side of the partition wall is formed to correspond to the same shape as the lateral groove at the same height position as the lateral groove, and the width of the name plate is It is half the width of the terminal block unit.

Function When the name plate is inserted into the horizontal groove of the side plate of the terminal block, the name plate is hung horizontally on the terminal block. A portion of the name plate hooks onto the inclined surface of the horizontal groove and is held in that position by the elasticity of the name plate. This name plate can be slid to the right or left. In this case, the name plate is slidable in the area of the transverse groove.

Embodiments Hereinafter, embodiments of the terminal block according to the present invention will be described.

FIG. 1 is a perspective view schematically showing the appearance of an embodiment of the terminal block according to the present invention. In the figure, 10 is a terminal block unit that includes one relay terminal 11 and is integrally formed with insulating resin, and 30 is a terminal block unit that is integrally formed with insulating resin that holds the connected terminal block units 10 from both sides like a so-called book end. This is the formed side block. Therefore, the terminal block shown in FIG. 1 is composed of four terminal block units 10 and two side blocks 30.

The relay terminal 11 is a metal plate 1 which is a rectangular conductor.
2 and a screw 15 screwed onto both ends of the metal plate 12 via a washer 13 and a spring washer 14. The terminal block unit 10 has each relay terminal 1.
1 and a partition wall 16 for separating the relay terminals 1 and 1.
The cross section is "C", which is erected on both sides of one side of the partition wall 16 with the opening facing inward to support the partition wall 16.
An arm 17 in the shape of a square, a locking piece 18 installed along the curved surface of the arm 17 and whose terminal portion is connected to the bottom plate 19, and a shaft insertion tube installed in the center of the upper surface of the bottom plate 19. 20, provided on the side surface of the partition wall 16;
A hook-shaped member 22 is included on the upper surface of the shaft insertion tube 20 to work with a support base 21 to sandwich the metal plate 12 and to maintain the interval between the partition walls 16. The upper surface of the partition wall 16 has two horizontal surfaces 16A and 16B and an inclined surface 16C formed between the horizontal surfaces 16A and 16B.
It is formed from. Further, pins 23 are provided upright at the end portions of the side surfaces of the arms 17, respectively.

On the other hand, the side block 30 includes a side plate 31 and a base plate 32 which are connected and formed in an "L" shape. A lateral groove 33 is cut into the inner surface of the side plate 31 so as to face the upper surface of the partition wall 16 . The position of this lateral groove 33, that is, the height from the bottom of the base plate 32 is set to be equal to the height from the bottom of the terminal block unit 10. Further, the shape of the lateral groove 33 corresponds to the horizontal surfaces 16A, 16B and the inclined surface 16C.
are formed respectively. Therefore, when the side block 30 is attached to the terminal block unit 10, a slight gap is created between the horizontal groove 33 and the top surface of the partition wall 16, and the name plate 40 can be inserted into this gap. There is.

A locking portion 34 is provided on the outside of the side block 30 integrally with the side plate 31. Then, the side plate 3 is placed coaxially with the shaft rod insertion tube 20 of the terminal block unit 10.
A through hole 35 is formed in the locking portion 1 and the locking portion 34.
A screw 36 is inserted into the locking portion 34 from above so as to pass through the through hole 35.
6 is screwed into a metal piece 37 inserted from the outer surface of the locking part 34.

A U-shaped stepped notch 38 is formed in the center of the outer surface of the base plate 32.

40 has name plates at both ends and is formed into a rectangular shape. The name plate 40 has a length that fits into the horizontal grooves 33, 33 of the two side blocks 30, a width that is half the width of the horizontal grooves 33, and is made of a thin plate of elastic insulating resin.

The shaft rod 50 is inserted into the shaft rod insertion tube 20 of the terminal block unit 10 having the above-described structure, and the side blocks 30 are fitted into both ends of the shaft rod 50. Then, by inserting the pins 23 of the terminal block unit 10 into the corresponding small holes (not shown in the figure) drilled in the partition wall 16 or side plate 31, and tightening the screws 36 of the side block 30, the terminals can be assembled. The base unit 10 and the side block 30 are fixed to each other. By slidably fitting both ends of the name plate 40 into the side plate 33 of the terminal block assembled in this way, the name plate 40 is horizontally hung on the terminal block. FIG. 1 shows a state in which the name plate 40 is fitted into the horizontal groove 33. In this figure, the name plate 40 is located on the left side of the drawing, most of the name plate 40 is on the horizontal surface 16A, and a part is on a part of the inclined surface 16C, so the name plate 40
remains stable at that position unless an external force is applied in the width direction. In this case, the wiring or wiring can be removed from the right side of the terminal block unit 10. When performing wiring on the left side, it is sufficient to slide the name plate 40 to the right side. In this case, the name plate 40 hits the horizontal surface 16B and the inclined surface 16C and stops at that position.

In addition, in the above embodiment, the terminal block unit 1
0 and the side block 30 have been described as being fixed by being inserted into the shaft rod 50.
These can also be applied to a terminal block of the type in which the locking pieces 18 shown in the embodiment are fixed by, for example, having a rail inserted into the inner curved portion thereof.

Effects of the Invention As is clear from the description of the embodiments above, the terminal block according to the present invention is achieved by slidably fitting both ends of the name plate into the horizontal groove cut into the inner surface of the side plate of the side block. Since the name plate is horizontally mounted on the top surface of the terminal block, tools such as a screwdriver are not required when sliding the name plate, making handling easier and reducing the number of screws and other parts. . Furthermore, when the name plate is slid, it is improved so that this sliding can be performed only within the width area of the terminal block unit, so that it is possible to completely prevent the name plate from protruding. Another effect is that since a portion of the name plate hits (catches) the inclined surface, the name plate does not slip off even when the terminal block is mounted vertically, for example.
