BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal block with a movable portion for fixing a main bar and a branch bar in a distribution board at right angles.

[0002]

2. Description of the Related Art A main bar and a branch bar connected to a circuit breaker of a distribution board are loosely heated due to vibration, generate heat, are displaced by external force, damage a coating, or are short-circuited by contact with equipment. Usually, it is fixed in the panel using a clamp terminal block so as not to cause an accident. As a pressing terminal block of this type, for example, a technique shown in FIG. 4A is conventionally known. 4A is a perspective view showing a conventional clamping terminal block, FIG. 4B is an explanatory view showing how to attach the clamping terminal block, a main bar and a branch bar, and FIG. 4C is the clamping after the attachment. It is sectional drawing of a terminal block.

[0003] A conventional clamping terminal block 10 comprises a base member 1.
1 and a tightening screw 12 screwed to the base member 11
The main body bar 14 is inserted through insertion windows 13, 13 formed in advance at both lower ends of a required number of base members 11, and the main bar 14 is divided by a fixture (not shown). Stick to the board. Then, as shown in FIG.
After inserting the branch bar 15 into the space defined by the base member 11 and the main bar 14, as shown in FIG.
2, the main bar 14 and the branch bar 15 are tightly fixed.

[0004]

[Problems to be Solved by the Invention] However, according to the above-mentioned clamping terminal block, it is necessary to insert the necessary number of trunk bars in advance. In addition to the work of removing the fixture from each fixture, it is not only time-consuming, but also the main bar provided below the already fixed branch bar has to be removed to the branch bar.

An object of the present invention is to provide a pressing terminal block which can be easily fixed to a main bar and a branch bar fixed inside a distribution board.

[0006]

In order to solve the above-mentioned problems, a pressing terminal block with a movable portion according to the present invention has a screw hole for hanging a holding portion and screwing a fastening screw on a top surface and a bottom surface. A main body provided with a support portion that penetrates and rotatably supports the movable piece on the side surface, a tightening screw screwed on the upper surface of the main body, a spring nut screwed to the tightening screw, and the support portion. It has a rotating shaft to be supported, and a movable piece from which the holding portion hangs down from the rotating shaft, and a protruding piece is provided opposite to a tip of the holding portion of the main body and the movable piece. Things.

[0007]

In the pressing terminal block with a movable portion according to the present invention, the movable piece is rotated to fit the pressing terminal block into the intersection of the main bar and the branch bar, and the intersection of the bars is clamped by the projection of the holding portion. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. FIG. 1 is a front view showing a use state of a movable terminal clamping terminal block. FIG. 2 is an exploded perspective view of the movable terminal clamping terminal block shown in FIG. FIG. 3 is an explanatory view showing a state in which the annular member of the pressing terminal block with movable portion in FIG. 1 is mounted on the main bar and the branch bar.

As shown in FIG. 2, a pressing terminal block with a movable portion according to this embodiment includes a main body 20 made of a synthetic resin material.
A tightening screw 30 screwed into a screw hole 24 formed in the upper surface of the main body 20, a spring nut 31 screwed to the tightening screw 30, and a movable synthetic resin supported by the main body 20. It is composed of five parts including a piece 40.
The lower surface of the main body 20 supports the main bar 14 from below.
The holding portions 21, 21 having a character-like shape are hung down,
A support portion 22 that rotatably supports the movable piece 40 is provided on a side portion of the main body 20 in a direction parallel to the L-shaped projection pieces 23 of the first and second L-shaped. The holding portion 21 may be provided not only on the lower surface of the main body 20 but also on the side surface of the main body. The support part 22
The spring nut 31 has a concave cross section and is screwed to the tightening screw 30. The movable piece 40 has a rotating shaft 41 supported by the support portion 22 and L-shaped holding portions 42, 42 that support the main bar 14 from below at both ends of the rotating shaft 41. . At the tip of the holding portions 42, 42, a projecting piece 43 opposed to the projecting piece 23 of the holding portion 21 of the main body 20 is protruded, and the both projecting pieces 23, 43 face each other. A fastening portion 44 is provided between the holding portions 42 of the rotating shaft 41 to prevent the spring nut 31 detached from the fastening screw 30 from jumping out of the main body.

In the pressing terminal block with a movable portion, first, a spring nut 31 is inserted into the support portion 22, and is slightly screwed by a tightening screw 30 screwed into the screw hole 24 so as not to fall. Next, the movable piece 40 is supported on the support portion 22 to complete the clamped terminal block with a movable portion. No extra member is required other than the clamped terminal block with the movable portion. In the present invention,
The pressing terminal block with a movable part is not limited to being made of synthetic resin, but may be made of aluminum die-cast or sheet metal. In addition, the spring nut 31 may be not only an integrated picket but also a spring washer and a nut separately.

In the case of fixing by using the pressing terminal block with the movable portion constructed as described above, first, the main bar 14 and the branch bar 15 are appropriately fixed to a circuit breaker (not shown). Next, as shown in FIG. 1, while lifting the movable piece 40 of the pressing terminal block with a movable part,
The main body 20 is placed on the intersection of the main bar and the branch bar so that the branch bar 15 is supported between the main bar 1 and the main bar 14 so that the holding portions 21 support the main bar 14 from below. By lowering the movable piece 40 that has been lifted, the branch bar 15 is placed between the holding portions 42, 42 of the movable piece 40,
Sandwiches the main bar 14 and crosses the main bar 1 below.
4 is supported by the projecting pieces 23 and 43. Next, FIG.
When the tightening screw 30 is tightened as shown in (1), the tip presses the branch bar 15 on the intersection, and the intersection of the main bar 14 and the branch bar 15 is gradually fixed by the action of the spring nut 31. Is done.

[0012]

As described in detail above, the clamping terminal block with a movable portion according to the present invention can be easily attached to the intersection of the main bar and the branch bar fixed in advance, and the main bar and the branch bar can be attached. Even after fixing, the spring terminal has the excellent effect that the clamping terminal block with movable part can be retrofitted.In addition, the spring nut is slightly screwed into the tightening screw, and comes off in the main body by the fastening part of the movable piece. The nut can be prevented from popping out, and the main bar and the branch bar can always be tightly fixed without losing the spring nut, and the benefit is enormous.
