JP 2010-165501 A

  By the way, the conventional short-circuit member is not limited to one in which adjacent terminal blocks are continuously short-circuited, but there is also one in which terminal blocks are short-circuited every other unit or every other unit. For example, in the short-circuit member 1c shown in FIG. 19, the interval between the connecting legs 4 is twice the thickness of the terminal block 51. When the short-circuit member 1c is mounted on the collective terminal block 50, the collective terminal block 50 is formed. Every other terminal block 51 is short-circuited.

  Here, as shown in FIG. 20, when the conventional short-circuit member 1 c is attached to the collective terminal block 50, each connection leg is inserted into each terminal block 51 and becomes invisible. In the example of FIG. 20, two short-circuit members 1c are mounted on the collective terminal block 50 so that the connecting legs are staggered, and the terminal blocks 51 of the collective terminal block 50 are alternately A and B poles. However, since the connection leg portion is not visible, it is difficult to distinguish which terminal block 51 is short-circuited by the short-circuit member 1c. In the collective terminal block 50, as shown in FIG. 20, the attribute of each terminal block 51 is printed on the name plate B attached to the upper portion, and the terminal blocks having the same description on the name plate B are short-circuited to each other. However, it is difficult to grasp at a glance the terminal blocks 51 that are short-circuited with each other in the description on the name plate B, and it is difficult to understand the circuit configuration of the collective terminal block 50.

  The present invention has been made in view of the present situation, and an object of the present invention is to provide a configuration in which the terminal block short-circuited by the short-circuit member can be easily identified in the short-circuit member of the collective terminal block.

  The present invention includes a conductive piece formed by juxtaposing a plurality of downwardly extending connecting legs on the lower edge side of the connecting base portion extending in the width direction, and an insulating resin piece covering at least the upper portion of the conductive piece. Insert a connection leg into the short-circuit member insertion part of each terminal block, and connect each connection leg to the terminal block. In the short-circuit member of the collective terminal block that is short-circuited between the conductive brackets of the plurality of terminal blocks by the conductive piece by being electrically connected to the bracket, an identification portion having an uneven shape is formed on the upper surface of the insulating resin piece. And the identification part is configured by a first identification shape formed in an upper part of the connecting leg part and a second identification shape formed in a part other than the formation part of the first identification shape. Connection by the difference between the shape of the identification shape and the second identification shape Parts is a short-circuit member of the set terminal block, characterized in that it made possible the identification of the terminal block to be connected from above.

  In such a configuration, which terminal block is short-circuited by the short-circuit member can be grasped by the identification unit of the short-circuit member. That is, the terminal block of the portion corresponding to the formation part of the first identification shape in a state of being attached to the collective terminal block is a terminal block that is short-circuited by connecting to the connection leg, and the second identification shape The terminal block corresponding to the formation site is not connected to the connection leg and is not short-circuited. Since this identification part is formed in the upper surface of a short circuit member, there exists an advantage that the position of a connection leg part can be grasped | ascertained easily. In addition, the identification portion having a concavo-convex shape can be easily manufactured as compared with painting and printing, and has excellent resistance to wear and dirt.

  In the present invention, at least one of the first identification shape and the second identification shape constitutes a tool fitting portion having a concavo-convex shape that can be fitted to the tip of the tool, and the tip of the tool is inserted into the tool fitting. It is proposed that it is configured to be fitted into the joint and pressed downward.

  With this configuration, the short-circuit member can be easily attached to the collective terminal block. That is, when mounting the short-circuit member on the collective terminal block, it takes a force to insert the connecting leg portion into the short-circuit member insertion portion of the terminal block, which may take time, but according to such a configuration, the tool Thus, the short-circuit member can be pushed down with a strong force, so that the connecting leg can be easily inserted into the short-circuit member insertion portion as compared with the conventional configuration. Moreover, in this structure, since the uneven | corrugated shape of an identification part comprises the tool fitting part fitted with the front-end | tip of a tool, the effort which forms a tool fitting part on the upper surface of an insulating resin piece can be saved.

  Further, in the above configuration, the lead wire is used in a collective terminal block including a screw type terminal block that fixes the end portion of the lead wire with a mounting screw having a cross hole, and the tool fitting portion is a cross-shaped concave portion. A configuration is proposed.

  In such a configuration, since the driver for rotating the mounting screw can be used as a tool for pushing down the short-circuit member, it is not necessary to separately prepare a tool for pushing down the short-circuit member.

  Moreover, in the said structure, the structure with which the tool fitting part is provided in the both sides of the insulating resin piece is proposed.

  In such a configuration, the short-circuit member can be pushed down one side at a time using a tool, so that the short-circuit member can be attached to the collective terminal block with a weaker force than when the short-circuit member is pushed down at a time.

  As described above, according to the present invention, it is possible to easily grasp which terminal block of the collective terminal block is short-circuited by the short-circuit member by confirming the uneven shape of the identification portion of the short-circuit member. Here, since an identification part is formed in the upper end of a short circuit member, there exists an advantage that the terminal block short-circuited by the said short circuit member can be understood intuitively. Further, the uneven shape of the identification part is easy to manufacture, and there is an advantage that visibility is less likely to deteriorate due to dirt or wear.

  Embodiments of the present invention are described according to the following examples.

  As shown in FIGS. 1-4, the short circuit member 1 of a present Example has comprised the comb-tooth plate shape. The short-circuit member 1 is formed by covering an upper part of a comb-like metal conductive piece 2 with an insulating resin piece 3. The conductive piece 2 includes six connection legs 4, and the short-circuit member 1 shorts between the six terminal blocks 51 by connecting the connection legs 4 to the terminal blocks 51 constituting the collective terminal block 50. To do. Here, as shown in FIG. 9, the connection legs 4 are arranged at intervals of twice the thickness of the terminal block 51, whereby each connection leg 4 is connected to the terminal block 51 of the collective terminal block 50. Legs 4 are configured to connect every other unit. Moreover, the insulator rod through-hole 10 used when extracting from the terminal block 51 penetrates the upper part of the short circuit member 1 in the thickness direction, and the identification part 30 according to the present invention is formed on the upper surface of the short circuit member 1. Is formed.

  As shown in FIGS. 4 and 5, the conductive piece 2 is formed by laminating two metal plates 20 a and 20 b in the thickness direction, and extends downward on the lower edge of the connecting base portion 5 extending in the width direction. It has a comb-teeth shape in which the connecting leg portions 4 of the book are juxtaposed. The connection leg portion 4 is branched into two branch leg portions 6 and 6 by a notch groove 7 in the vertical direction. Each branch leg 6, 6 can bend in the width direction. As will be described later, the connection leg 4 has a short-circuit opening 60 (see FIG. 8)). In addition, extending portions 11 that extend upward are formed at three locations on both sides and the central portion of the connecting base portion 5. Each extending portion 11 is provided with a substantially rectangular through hole 10a that forms the insulator rod through hole 10 in the thickness direction. Further, locking claws 9 for engaging with the insulating resin piece 3 are formed on both sides of the upper portion of each extending portion 11.

  The insulating resin piece 3 is manufactured as a single part by molding an insulating resin such as nylon. As shown in FIGS. 4 and 6, the insulating resin piece 3 is formed with a coupling groove 17 that opens downward. The coupling groove 17 has such a shape that the base end side of the connecting base portion 5 and the connecting leg portion 4 of the conductive piece 2 can be closely fitted, and when the conductive piece 2 is fitted into the coupling groove 17 of the insulating resin piece 3. The locking claw 9 formed on the coupling base 5 bites into the inner wall of the coupling groove 17 and is assembled inseparably so that the short-circuit member 1 is completed. In addition, a substantially rectangular through hole 10b is formed in the thickness direction on the insulating resin piece 3. The through-hole 10b is formed so as to overlap with the through-hole 10a of the connecting base 5 in the thickness direction in a state in which the conductive piece 2 is closely fitted to form the lever rod through-hole 10.

  Moreover, the identification part 30 which consists of uneven | corrugated shape is formed in the upper surface of the insulating resin piece 3, as shown in FIGS. This identification part 30 is provided with the 1st identification shape 31 comprised by the circular convex part, and the 2nd identification shape 32 comprised by the parallel double line-shaped convex part along the width direction. The first identification shape 31 is formed at a portion of the identification portion 30 that is directly above the connecting leg portion 4, and the second identification shape 32 is formed at all portions except the formation portion of the first identification shape 31.

  Here, as shown in FIGS. 3 and 6, a concave groove 34 in a direction perpendicular to the width direction is formed on the parallel double-line convex portion of the second identification shape 32, and the concave groove 34 is A cross-shaped concave portion 33 is formed in the second identification shape 32 by being orthogonal to the concave groove 35 formed between the parallel two-line-shaped convex portions. The cross-shaped concave portion 33 constitutes a tool fitting portion that is fitted to the tip of a driver (tool).

  7 and 8 show a terminal block (screw type terminal block) 51 that is short-circuited by the short-circuit member 1. The terminal block 51 has a symmetrical resin substrate 52 formed in a plate shape by an insulating resin material such as a modified PPO resin as a main part, and as shown in FIG. 9, a metal installation rail A The collective terminal block 50 is formed in a plurality of rows. A plate-shaped conductive metal 53 is mounted on the resin substrate 52 in a transverse manner. Flat connection pieces 61 and 61 for connecting the lead wires L are formed on both sides of the conductive metal 53. A movable washer member 54 is held on each connecting piece 61 so as to be movable up and down, and a mounting screw 55 having a cross hole 58 in the head is inserted into and attached to the movable washer member 54. Specifically, as shown in FIGS. 10 and 11, the terminal block 51 is mounted on the resin substrate 52 after the movable washer member 54 and the mounting screw 55 are assembled on both sides of the conductive metal 53, and each movable block is further movable. Assembling is performed by mounting a compression coil spring 56 that urges the movable washer member 54 upward between the lower end of the washer member 54 and the bottom of the resin substrate 52.

  As shown in FIG. 10, the resin substrate 52 of the terminal block 51 has a seating groove surface on which the conductive metal 53 and the movable washer member 54 are mounted by projecting a defined wall 82 having a predetermined thickness from the back plate 81. 83 or the like is formed open on the front side. Further, at the bottom of the resin substrate 52, connecting pieces 84, 84 that engage with the upper portion of the installation rail A are formed.

  As shown in FIG. 11, the conductive metal fitting 53 is made of a long strip of metal strip that is not easily worn or deformed. The conductive metal piece 53 is formed by connecting a pair of left and right flat plate-like connecting pieces 61, 61 without any step, and has a symmetrical shape. A drawing process is applied downward at a position near the end of the connection piece 61, and a screw hole 62 that is screwed into the attachment screw 55 is formed in the processed part. A rectangular washer opening 64 through which the guide piece 72 of the movable washer member 54 passes is formed in the vicinity of the inside of the screw hole 62, and the short-circuit member 1 is connected in the vicinity of the inside of the washer opening 64. A rectangular short-circuiting opening 60, 60 into which the leg 4 is fitted is formed.

  As shown in FIG. 11, the movable washer member 54 is formed by bending a punched metal plate piece so that the flat washer piece portion 71 and the hook-like guide piece portion 72 are substantially orthogonal to each other. It has an L shape that is coupled. In the center of the washer piece 71, a screw insertion hole 74 through which the attachment screw 55 is inserted is provided. In addition, a press-contact protrusion 75 that strongly presses the crimp terminal T is raised around the screw insertion hole 74 on the lower surface of the washer piece portion 71. On the other hand, the guide piece 72 has a straight shape with no irregularities and hangs down from the edge of the washer piece 71 in a direction perpendicular to the washer piece 71. The lower end of the guide piece 72 is narrower than the center so that only the lower end of the guide piece 72 can be fitted into the compression coil spring 56. Further, the movable washer member 54 is formed with an engagement piece portion 73 that protrudes upward from the edge of the washer piece portion 71 and engages with the resin substrate 52.

  As shown in FIGS. 7 and 8, the terminal block 51 is formed with one vertical short-circuit member insertion portion 57 opened in the upper part, one at a left-right symmetrical position. Each short-circuit member insertion portion 57 has a width dimension in which the connection leg portion 4 of the short-circuit member 1 can be inserted, and a short-circuit opening 60 of the conductive metal 53 is located in a deep portion thereof. Further, a support wall portion 87 is erected on the side of the opening of each short-circuit member insertion portion 57. The wall surface of the support wall portion 87 is continuous with the inner wall surface of the short-circuit member insertion portion 57 and functions as a guide when the short-circuit member 1 is attached and detached.

  When connecting the lead wire L to the terminal block 51, the crimp terminal T at the end of the lead wire L is connected to the movable washer member 54 with the movable washer member 54 raised as shown on the left side of FIG. Then, the movable washer member 54 is lowered against the urging force of the compression coil spring 56, and a mounting screw 55 is screwed onto the connection piece 61 using a screwdriver. The crimp terminal T is clamped between the member 54 and the connection piece 61 so as not to fall off.

  When releasing the connection of the crimp terminal T, the attachment screw 55 may be loosened using a screwdriver. When the mounting screw 55 is removed from the screw hole 62, the movable washer member 54 is automatically raised by the compression coil spring 56. Therefore, the crimp terminal T can be extracted without lifting the movable washer member 54.

  When the short-circuit member 1 is mounted on the collective terminal block 50 including the terminal block 51, the connection legs 4 of the short-circuit member 1 are inserted into the short-circuit member insertion portion 57 from above as shown in FIG. When the connecting leg 4 is inserted to some extent, the tip of the connecting leg 4 reaches the short-circuit opening 60 of the conductive metal 53 (see FIG. 12A). Then, when the short-circuit member 1 is further inserted, the connecting leg 4 is press-fitted into the short-circuit opening 60 while bending each branch leg 6 inward (see FIG. 12B). In this way, when the connection leg portion 4 is inserted to the back of the short-circuit member insertion portion 57, the branch leg portion 6 is in elastic contact with the inner edge of the short-circuit opening 60, so that the conductive piece 2 and the conductive metal piece 53 are electrically connected. While being connected, the short-circuit member 1 is held difficult to pull out from the terminal block 51.

  Here, in this embodiment, as shown in FIG. 14, the short-circuit member 1 can be strongly pushed down using the driver D by fitting the tip of the driver D to the tool fitting portion 33 on the upper surface of the short-circuit member 1. Therefore, there is an advantage that the connecting leg 4 can be easily press-fitted into the short-circuit opening 60. In particular, since the tool fitting portions 33 are formed at equal intervals along the longitudinal direction of the identification portion 30 and are also formed on both sides of the insulating resin piece 3, the entire short-circuit member 1 is pushed down by the driver D at once. Instead, as shown in FIG. 14, the short-circuit member 1 can be pushed in twice on one side.

  When the short-circuit member 1 is mounted on the collective terminal block 50, the six terminal blocks 51 to which the connection legs 4 are connected are connected to each other via the conductive piece 2. Here, when the short-circuit member 1 is mounted, the connecting leg 4 inserted into the terminal block 51 is not visible from the outside, but as shown in FIG. 15, the identification portion 30 of the short-circuit member 1 is visible from above. Since this is possible, it is possible to know which terminal block 51 is connected to the connection leg 4 by the identification unit 30. That is, in the identification unit 30, the terminal block 51 where the first identification shape 31 exists is the terminal block 51 to which the connection leg 4 is connected, and the terminal block 51 where the second identification shape 32 exists is the connection leg. This is a terminal block 51 to which the unit 4 is not connected. Thus, in this embodiment, which terminal block 51 is short-circuited by the short-circuit member 1 can be confirmed by the identification unit 30 of the short-circuit member 1.

  Further, when removing the mounted short-circuit member 1 from the collective terminal block 50, as shown in FIG. 16, the driver D is inserted into the lever rod through hole 10 from the inside, and the tip of the driver D is brought into contact with the support wall portion 87. If the inner side of the lever rod through hole 10 is pressed upward by the tip of the driver D by lever action with the upper edge of the support wall 87 on the other side as a fulcrum while being in contact with each other, each connection leg 4 is opened to the short-circuit opening. The short-circuit member 1 can be extracted from the short-circuit member insertion portion 57 by dropping from the short-circuit member 60.

  As described above, the short-circuit member 1 according to the present embodiment can identify the formation part and the non-formation part of the connection leg 4 by the identification part 30 formed on the upper surface. Even in a state where the portion 4 is not visible, it is possible to grasp at a glance which terminal block 51 is short-circuited by the short-circuit member 1 and which terminal block 51 is not short-circuited. For example, in the collective terminal block 50 shown in FIG. 17, the short-circuit members 1 and 1 are mounted on both sides. In the collective terminal block 50, since the terminal block 51 of the portion having the first identification shape 31 is the terminal block 51 short-circuited by the short-circuit member 1, in the example shown in FIG. It is short-circuited by the short-circuit member 1 so that every other terminal block 51 becomes the A pole, and the short-circuit member 1 on the near side in the drawing is short-circuited so that every other terminal block 51 becomes the B-pole. Easy to grasp. As described above, in the short-circuit member 1 of the present embodiment, which terminal block 51 is short-circuited and which terminal block 51 is short-circuited due to the difference in the uneven shape of the identification unit 30 without understanding the description of the name plate B. There is an advantage that it can be grasped at a glance from above.

  In particular, since the identification part 30 of the short-circuit member 1 has an uneven shape formed on the insulating resin piece 3, when compared with the name plate B, there is an advantage that visibility is hardly deteriorated due to dirt or wear. Moreover, since the identification part 30 only needs to form an uneven | corrugated shape at the time of the shaping | molding of the insulating resin piece 3, there exists an advantage that it can form easily compared with printing and coating to the insulating resin piece 3. FIG. . Moreover, since the identification part 30 is formed in the upper surface of the short circuit member 1, compared with the name plate B, there exists an advantage that the formation site | part of the connection leg part 4 can be understood intuitively.

  Further, since the short-circuit member 1 of the present embodiment is configured so that the tip of the driver D can be fitted to the tool fitting portion 33 formed in the identification portion 30 and pressed downward, the short-circuit member 1 is There is an advantage that it can be pushed into the collective terminal block 50 with a strong force. In particular, in the present embodiment, since the tool fitting portion 33 is a cross-shaped recess, there is an advantage that the driver D that rotates the mounting screw 55 can be used as a tool for pressing the short-circuit member 1. Moreover, since the tool fitting part 33 is formed in the both sides of the short circuit member 1, and the short circuit member 1 can be press-fitted into the collection terminal block 50 one side at a time using the driver D, the short circuit member 1 is press-fitted at a time. Compared with the case where it does, there also exists an advantage that the force which pushes down the short circuit member 1 may be weak.

  In addition, the short circuit member in this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention.

  For example, in the above-described embodiment, the first identification shape 31 of the identification unit 30 is formed at a position directly above the connection leg 4, but the first identification shape according to the present invention is the direct identification of the connection leg. It is not limited to the above, and it is sufficient if the terminal block is disposed above the connection leg so that the terminal block to which the connection leg is connected can be identified. Moreover, in the said Example, although the 1st identification shape 31 has a circular convex part, and the 2nd identification shape 32 becomes a structure which has a parallel double linear convex part, a 1st identification shape and a 2nd identification shape are comprised. The uneven shape of the shape should just differ to such an extent that both can be distinguished. For example, like the identification part 30a of the short-circuit member 1a shown in FIG. 18A, the first identification shape 31a has a cross-hole-shaped tool fitting part 33a, and the second identification shape 32a has a flat shape. It may be. Moreover, you may comprise so that the 1st identification shape 31b may be dented one step | paragraph with respect to the 2nd identification shape 32b like the identification part 30b of the short circuit member 1b shown in FIG.18 (b).

  Moreover, although the short circuit member 1 of the said Example is the structure provided with the six connection leg parts 4, the short circuit member which concerns on this invention should just be provided with two or more connection leg parts. Moreover, although the connection leg part 4 is arrange | positioned by the space | interval which short-circuits every other terminal block 51, the short circuit member 1 of the said Example exists in the short circuit member of this invention, and arrangement | positioning of a connection leg part The intervals can be changed as appropriate, and the arrangement intervals need not be equal. Also, the configuration of the connecting leg can be variously changed.

  Moreover, in the said Example, although the conduction | electrical_connection piece 2 was comprised by the two metal plates 20a and 20b, the metal plate which comprises a conduction | electrical_connection piece may be one sheet, and three or more sheets may be sufficient as it.

  Moreover, in the said Example, the terminal block 51 which mounts the short circuit member 1 only illustrated the well-known terminal block, and the short circuit member of this invention is not limited to said terminal block 51, but various types of terminals. Can be mounted on a table. For example, the terminal block 51 is a screw-type terminal block that fixes the crimp terminal T with the mounting screw 55. However, the short-circuit member of the present invention is not limited to such a screw-type terminal block, and the crimp terminal and the lead wire are spring-loaded. It can also be applied to terminal blocks that are fixed with Further, the number of lead wires connected to the terminal block is not limited to two, and the number of short-circuit member insertion portions can be changed as appropriate.
