Description

  The present invention relates to a terminal block cover mechanism that covers a terminal mounting portion of a terminal block to which end portions of various conductive wires are screwed.

  In various types of electronic devices, switchboards, control panels, and the like, a terminal block is usually used in order to make electrical connection between each device incorporated inside and each device provided outside. That is, this terminal block is used as a relay part for connecting various conductive wires drawn from each device. In general, this type of terminal block has a plurality of terminal mounting portions to which terminals of conductive wires are screwed to a base formed of an insulator. In addition, a partition wall formed integrally with the terminal block is provided between the terminal mounting portions. Thereby, each terminal attachment part is in the state each divided, and it is considered so that the conductive wire screwed by each terminal attachment part may not short-circuit.

  In order to further enhance safety, a cover for preventing the conductive parts, fingers, and the like from being accidentally touched to each terminal mounting portion is mounted on the normal terminal block. There are several methods for mounting the cover, but generally, the terminal block or a mounting surface to which the terminal block is attached is screwed. As a method other than screwing, the cover is once bent into a U shape, and the claws formed at both ends of the cover are inserted into the grooves formed in the terminal block, and then the cover is uncurved and the claws are released. A method of engaging the groove with the groove is also known.

However, the method of screwing the cover requires a tool every time the cover is removed, so that it takes time and effort and causes a reduction in work efficiency. In addition to this, if the removed screw is accidentally brought into contact with the terminal mounting portion, the terminal mounting portion may be short-circuited. Furthermore, the removed screw may be lost.
On the other hand, since the method of attaching the cover once bent does not require a tool or a screw, the above-mentioned problem does not occur. However, since the cover needs to be bent, the cover itself needs to be made of a soft material. For this reason, the rigidity of the cover itself is lowered, and the reliability as the cover is poor. Therefore, a terminal block that does not require a tool and does not require elastic deformation of the cover is provided (see Patent Document 1).

However, the conventional terminal block still has the following problems.
That is, in the terminal block described in Patent Document 1, in order to fix the cover, a groove for slidingly inserting the cover into the terminal block side, or a protrusion shape for engaging with an engagement hole formed in the cover. It is necessary to process the engaging part. Therefore, a general terminal block that is widely used cannot be used as it is. Therefore, when a problem occurs in the terminal block, it is necessary to prepare a dedicated one again, which requires a running cost.

  The present invention has been made in view of such circumstances, and its purpose is to cover the terminal mounting portion of a generally used terminal block with a simple manual operation without using a tool. It is providing the cover mechanism for terminal blocks which can do.

In addition, the fixing bracket 20 is fixed to the terminal block 5 using the screws 4 while being accommodated in the notch 2c.

As shown in FIG. 8, the cover member 21 is formed in a substantially rectangular shape as shown in FIG. 8, and an insertion hole 21a through which the spacer portion 20a is inserted is formed on one end side. The cover member 21 is prevented from being removed by the washer 8 and the screw 4 in a state where the spacer portion 20a is inserted into the insertion hole 21a. As a result, the cover member 21 is rotatably connected to the one spacer portion 20a. As shown in FIG. 7, the cover member 21 rotates about the axis L and is closed as described above. And the open position P2 can be displaced.
Further, on the other end side of the cover member 21, when the cover member 21 is positioned at the closed position P1, the fitting groove 21b is fitted to the other spacer portion 20a to hold the cover member 21 at the closed position P1. Is formed. Furthermore, a bent portion 21 c that is bent at a substantially right angle is formed on one side of the cover member 21. When the cover member 21 is held at the closed position P1, the bent portion 21c abuts against the side surface of the base 2 to form a gap between the cover member 21 and the base 2 as shown in FIG. It is designed to shield.

Next, the operation of the terminal block cover mechanism 1 configured as described above will be described.
First, before attaching the terminal block 5 to the mounting surface S using the screws 4 provided at both ends of the base 2, the fixing bracket 20 is accommodated in the notch 2c. At this time, the spacer portions 20 a of the pair of fixing brackets 20 are arranged at positions farther from the base 2 than the terminal mounting portions 3 at both ends of the base 2. Further, the insertion hole 21 a of the cover member 20 is inserted into the spacer portion 20 a of one fixing bracket 20. Next, using the screws 4 to which the terminal block 5 is attached, the pair of fixing brackets 20 are fixed to the base 2 while being fixed, and the base 2 is fixed to the mounting surface S. Thereby, the cover member 21 will be in the state connected rotatably with respect to one spacer part 20a.

  Next, as shown in FIG. 7, the cover member 21 is rotated around the axis L to be positioned at the open position P2. Thereby, the upper part of the some terminal attachment part 3 will be in the open state. Therefore, the worker can connect the conductive wire W without being obstructed by the cover member 21. In the present embodiment, the case where the conductive wire W is connected by pressing the terminal T crimped to the end of each conductive wire W against the conductive plate 7 with the washer 3b and the terminal screw 3a is taken as an example. Yes. Thereafter, by connecting an end portion of a conductive wire (not shown) to the other terminal mounting portion 6, the terminal block 5 functions as a relay part that connects the conductive wire and the conductive wire W.

  Then, after the connection work of the conductive wires W is completed, the cover member 21 is rotated from the open position P2 to the closed position P1, and the upper portions of the plurality of terminal attachment portions 3 are covered with the cover member 21. At this time, the fitting groove 21b formed on the other end side of the cover member 21 is pushed into the other spacer portion 20a to be fitted. Thereby, as shown in FIG.1 and FIG.2, the cover member 21 can be reliably hold | maintained in the closed position P1, and the state which covered the upper part of the some terminal attachment part 3 can be maintained.

Therefore, it is possible to prevent a plurality of terminal mounting parts 3 from being accidentally brought into contact with some conductive parts, fingers, etc., and to prevent a short circuit of the plurality of terminal mounting parts 3. Safety can be increased.
Moreover, when the cover member 21 is held at the closed position P1, as shown in FIG. 2, the bent portion 21c comes into contact with the side surface of the base 2 to shield the gap between the cover member 21 and the base 2. . Therefore, even if dust or the like enters between the terminal block 5 and the cover member 21 from the side of the terminal block 5, it can be shielded by the bent portion 21c. Therefore, it is possible to prevent dust and the like from adhering to the plurality of terminal mounting portions 3 as much as possible. Therefore, the possibility of a short circuit due to the adhesion of dust and the like can be reduced, and safety can be further improved.

Further, when removing the conductive wire W from the terminal mounting portion 3, the cover member 21 is rotated from the closed position P1 to the open position P2 after releasing the fitting between the fitting groove 21b and the other spacer portion 20a. Thereby, since the upper part of the some terminal attachment part 3 will be in the open state, the conductive wire W can be easily removed after that.
The other end side of the cover member 21 is formed to protrude outward from the terminal block 5 so that the operator can easily rotate the cover member 21.

  As described above, since the terminal mounting portion 3 can be covered by a simple manual operation by simply rotating the cover member 21 between the open position P2 and the closed position P1, a tool is not required and work efficiency is reduced. There is nothing. Further, since the cover member 21 is rotatably connected to the spacer portion 20a of the fixing bracket 20, there is no possibility of losing the cover member 21 during connection or removal of the conductive wire W. Further, since it is not necessary to bend the cover member 21 as in the prior art, the rigidity can be increased and the reliability as the cover can be increased.

In particular, since the pair of fixing metal fittings 20 are fixed using the screws 4 to which the terminal block 5 is attached, there is no need to process the terminal block 5 as in the prior art. Therefore, it can be used in combination with a general terminal block 5 that is widely used. Therefore, even if a failure occurs in the terminal block 5 itself, a general-purpose product can be used, and the running cost can be suppressed.
Further, since the cover member 21 is transparent, the connection state between the terminal mounting portion 3 and the conductive wire W can be confirmed through the cover member 21.

(Second Embodiment)
Next, a second embodiment of the terminal block cover mechanism according to the present invention will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the second embodiment and the first embodiment is that, in the first embodiment, the cover member 21 is connected to the fixing bracket 20, but in the second embodiment, the cover member 31 is detachable. It is a point.

That is, the terminal block cover mechanism 30 of this embodiment includes a cover member 31 having a pair of through portions 31a and fitting grooves 31b as shown in FIGS. The pair of penetrating portions 31a are formed at both ends of the cover member 31, respectively. When the cover member 31 is positioned at the closed position P1 covering the plurality of terminal mounting portions 3, the pair of spacer portions 20a are respectively penetrated. ing. In this embodiment, one through portion 31a is a through hole, and the other through portion 31a has a notched cutout groove tapered.

  Also, the cover member 31 of the present embodiment has a bent portion 31c formed on one side, as in the first embodiment. Furthermore, a bent portion 31d is formed on the other side, which is bent approximately 90 degrees by a slight length.

When using the terminal block cover mechanism 30 having the cover member 31 configured as described above, first, the terminal block with the pair of fixing brackets 20 attached to the base 2 as in the first embodiment. 5 is fixed to the mounting surface S. Next, a connection operation for connecting the conductive wires W to the plurality of terminal attachment portions 3 is performed. After this connection work is completed, the cover member 31 is overlaid on the terminal block 5. At this time, as shown in FIG. 11, the cover member 31 is overlapped with the penetrating portions 31 a formed at both ends in a state where the spacer portion 20 a is penetrated. Thereby, the upper part of the some terminal attachment part 3 can be covered with the cover member 31. FIG. Then, the cover groove 31 is slid in one direction along the longitudinal direction of the cover member 31 (the direction of the arrow A shown in FIG. 11) from the position where the cover member 31 is overlapped, and the fitting groove formed integrally with the through portion 31a. Each 31b is pushed into the spacer portion 20a to be fitted. Thereby, as shown in FIG.12 and FIG.13, the cover member 31 can be reliably hold | maintained in the closed position P1 which covers the some terminal attachment part 3, and the state which covered the upper part of the some terminal attachment part 3 is covered. Can be maintained.
In FIGS. 11 to 13, the conductive lines W are not shown in order to make the drawings easy to see.

Further, when removing the conductive wire W from the terminal attachment portion 3, the cover portion is slid in the reverse direction to release the fitting between the fitting groove 31 b and the spacer portion 20 a, and then the cover member 31 is removed. Thereby, since the upper part of the some terminal attachment part 3 will be in the open state, the conductive wire W can be easily removed after that.
Note that the cover member 31 of the present embodiment is also formed so that the other end protrudes outward from the terminal block 5 so that the operator can easily perform a slide operation, as in the first embodiment.

  As described above, also in the terminal block cover mechanism 30 of the present embodiment, as in the first embodiment, the terminal mounting portion of the terminal block 5 that is generally used by a simple manual operation without using a tool. 3 can be reliably covered. In particular, since the cover member 31 of the present embodiment has the bent portion 31d formed on the opposite side in addition to the bent portion 31c, the rigidity can be further increased and the reliability as the cover is higher. Further, it is possible to cope with a situation where it is difficult to rotate the cover member 31.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in each of the above-described embodiments, the terminal block 5 having the notch portions 2 c at both ends of the base 2 is taken as an example. However, the terminal block 5 is not limited to this. In addition, although the terminal block 5 in which the three terminal mounting portions 3 are arranged in the base 2 is taken as an example, the number of the terminal mounting portions 3 is not limited to three.

Further, in the second embodiment, the case where one through portion 31a is a through hole and the other through hole is a cut-out groove has been described as an example. However, both through portions 31a may be formed as through holes.
Moreover, when sliding the cover member 31, the case where it moved to the direction along the longitudinal direction of the cover member 31 was taken as an example, However, It is not limited to this direction. By changing the forming direction of the fitting groove 31b, it is possible to slide in a free direction. In this case, the bent portions 31c and 31d are not formed, and the flat cover member 31 may be used. However, the bent portions 31c and 31d can be formed in the cover member by forming the fitting groove 31b so as to be slidable in the direction along the longitudinal direction as in the present embodiment, so that the rigidity of the cover member 31 is increased. Is more preferable.
