  The present invention relates to a rail coupling member and a rail coupling structure for coupling, for example, rails to which instrumentation equipment or the like can be attached in an electric panel.

  Conventionally, in an electric panel, an instrument such as a signal converter is attached to, for example, a DIN (German Industrial Standard) rail (see, for example, Patent Document 1). When renewing and adding this instrumentation, many of them are downsized, so the current wiring may not be usable depending on the mounting position.

  In addition, since the DIN rail for device installation is only linear, if there is an obstacle such as another instrument at the position where the DIN rail is to be installed, the installation location is limited and the arrangement of the instrumentation is changed. May be necessary and current wiring may not be usable. Therefore, as instrumentation equipment is updated, the position of the DIN rail is shifted to a position where obstacles can be avoided, the wiring is changed (replacement of cables in the panel), and the DIN rail mounting support member (support) It is necessary to carry out in-panel modifications such as additional machining.

  As shown in FIG. 1, the rail coupling structure 1 of this embodiment is arranged in an electric panel 2, and DIN rails 3, 4, and 5 that can be attached to instrumentation equipment (equipment) are rail couplings. The arrangement direction is adjusted by the metal fittings 6a and 6b, and they are combined to form a schematic structure.

  For example, one end is supported by a support member (support) 7a, and the DIN rail 3 disposed along the horizontal direction and the DIN rail 4 disposed along the vertical direction are coupled by the rail coupling metal 6a. The DIN rail 5 and the DIN rail 4 which are supported at one end by the support member 7b and are arranged in the horizontal direction are coupled by the rail coupling bracket 6b, and thereby the obstacle 8 such as a meter is connected to the Interference is avoided. The DIN rails 3, 4, 5 and the rail coupling brackets 6a, 6b are made of, for example, aluminum. By attaching the instrumentation equipment to the DIN rails 3, 4, and 5, it is possible to attach and remove from the front side.

It has part 3a (4a, 5a), flange part 3b, 3b (4b, 4b, 5b, 5b), and collar part 3c, 3c (4c, 4c, 5c, 5c). The DIN rails 3 and 5 have a length of, for example, 250 mm and 500 mm, and the DIN rail 4 has a length of, for example, 100 mm and 150 mm, and are used for gap adjustment. Instrumentation equipment such as a signal converter Cannot be installed.

  As shown in FIGS. 2 to 4, the rail coupling bracket 6 a (6 b) is attached to the first mounting member 13 mounted on one DIN rail 3 (4, 5) and the other DIN rail 3 (4, 5). A second mounting member 14 to be mounted is schematically configured by being coupled using a fixing tool 15 such as a male screw.

  The first attachment member 13 (second attachment member 14) includes a web portion 13a (14a) in which a long hole 13r (14r) is formed, flange portions 13b and 13b (14b and 14b), and flange portions 13c and 13c ( 14c, 14c) and a coupling piece 13d (14d) extending from the web portion 13a (14a). The web portion 13a (14a), the flange portions 13b and 13b (14b and 14b), and the flange portions 13c and 13c (14c and 14c) are the web portions 3a (4a and 5a) of the DIN rail 3 (4 and 5).

It can be mounted in a state of being stacked from the front side.

  The first take-up member 13 and the second attachment member 14 are in a state in which the coupling pieces 13d and 14d are overlaid and in a state in which the angle formed between the lengthwise directions is adjusted. The posture is fixed by the fixture 15 arranged at 14d. For example, as shown in FIG. 2, when the adjusted angle is set to approximately 0 degrees, as shown in FIG. 5, both DIN rails 3 (4, 5) are used by using the rail fittings 6a (6b). Are coupled so that the angle in the lengthwise direction thereof is approximately 0 degrees.

In addition, as shown in FIG. 4, when the adjusted angle is set to approximately 90 degrees, as shown in FIG. 7, both DIN rails 3 (4, 5) are used by using the rail fittings 6a (6b). Are coupled so that the angle in the longitudinal direction thereof is approximately 90 degrees.

  In FIG. 1, one end of the DIN rail 3 is fixed to the support member 7a using a fixing plate 9 and a fixture 11 such as a male screw, bolt, or nut, and the other end is approximately 90 degrees. The rail coupling bracket 6a is bent to the first mounting member 13 by using the fixing plate 9 and the fixture 11. Further, one end of the DIN rail 4 is fixed to the second mounting member 14 of the rail coupling bracket 6a by using the fixing plate 9 and the fixing tool 11, and the other end is bent at approximately 90 degrees. It is fixed to the first mounting member 13 of the rail coupling bracket 6b using the fixing plate 9 and the fixture 11. Also, one end of the DIN rail 5 is fixed to the second mounting member 14 of the rail coupling bracket 6b using the fixing plate 9 and the fixture 11, and the other end is fixed to the support member 7a. 9 and a fixing tool 11 are used. Thus, as shown in FIG. 8, if the DIN rail 3 extends in the horizontal direction as it is, the obstacle 8 can be easily removed by changing the route even when the DIN rail 12 interferes with the obstacle 8. Therefore, it is not necessary to dispose the support member 7c in the intermediate portion.

  Thus, according to the configuration of this embodiment, for example, one end portion of the DIN rail 3 is fixed to the support member 7a, and the other end portion of the rail coupling bracket 6a bent at about 90 degrees. 1 is fixed to the mounting member 13, one end of the DIN rail 4 is fixed to the second mounting member 14 of the rail coupling bracket 6a, and the other end of the rail coupling bracket 6b bent approximately 90 degrees. The first mounting member 13 is fixed, one end of the DIN rail 5 is fixed to the second mounting member 14 of the rail coupling bracket 6b, and the other end is fixed to the support member 7a. The DIN rails 3, 4, and 5 are freely arranged to easily avoid the obstacle 8.

  Therefore, the instrumentation equipment attached to the DIN rails 3 and 5 can be updated easily and at low cost in the electric panel 2. That is, since the remodeling in the panel can be minimized, the operation cost can be reduced. Furthermore, in the case of replacement of an electric device, since it can be adjusted to the same position as the existing equipment, wiring change or the like is not necessary, and the possibility of maintaining the current situation is increased.

  In addition, since there is no need to change the wiring, the risk of erroneous wiring and the like can be reduced, and the instrumentation device can be reliably updated. Moreover, since additional processing of the support member (support) in the electric board 2 is unnecessary, there is no possibility of adversely affecting other devices in the electric board 2. Further, since the DIN rails 3, 4, and 5 can be arranged in different directions, the space in the electric panel 2 can be utilized to the maximum and the device can be attached.

  Next, a method for assembling the rail coupling bracket 17 will be described. First, the first mounting member 18 is assembled by screwing the male screw portion 18g into the female screw portion 18e of the support 18d and attaching the coupling portion 18f. Here, the male screw portion 18g is screwed into the female screw portion 18e to a predetermined depth, and the length of the entire first mounting member 18 is adjusted. Next, the male screw portion 19n is screwed into the female screw portion 19e of the support body 19d, and the coupling portion 19f is attached to assemble the second attachment member 19.
