Description

  The present invention relates to a rail-mounted outlet with a power supply simple connection type terminal portion.

  Conventionally, in order to maintain various devices such as a control panel for sequence control, various devices are tested and measured at a predetermined time using a portable computer in which a maintenance program is installed.

  In this case, a power outlet for supplying commercial power to the portable computer is required. However, although it is not uncommon for commercial power outlets to be pre-arranged on the pillars and walls of the office room adjacent to the maintenance work site, commercial power outlets are pre-arranged on the pillars and walls of the maintenance work site. In many cases, there is nothing.

  Therefore, a long electric wire with a plug inserted into the outlet of the office is prepared, and the electric wire is routed to the maintenance work site to be connected to the portable computer. However, this takes time to connect the power supply cable to the portable computer, and the progress of the maintenance work is delayed.

  Therefore, normally, an outlet for commercial power is installed in a place where the multi-stage equipment mounting rails where various devices are installed side by side in the control panel are installed, and the commercial power cable is connected to this outlet. To put.

  In this way, when a worker opens the control panel door for maintenance work, immediately find the outlet for commercial power in front of him and plug the electric wire drawn from the portable computer into the outlet. Since the power can be supplied immediately, the work progresses and is convenient.

  Originally, such an outlet for commercial power has been useless for the control panel itself for sequence control. However, in recent years, for the reasons described above, along with the original various devices, In such a place, an outlet for such a commercial power supply is attached for the convenience of the maintenance worker.

Such an outlet is called a service outlet or a temporary outlet for the purpose of use, and may be called an exposed outlet for its shape. (For example, refer nonpatent literature 1 and 2.)
FIG. 8 (a) is an external perspective view showing an example of the conventional outlet as described above, and FIG. 8 (b) is a perspective view seen from the back side thereof. As shown in FIGS. 1A and 1B, the outlet 1 is generally provided with a base 2 made of an insulating material such as a hard resin and a base protection lid 3. The base 2 is a raised bottom type, and a notch hole 4 for drawing a power supply wire is formed in one place around the base 2.

  In the raised bottom 5 of the base 2, two branch wiring drawing holes 6 for drawing two electrode wires branched from the two integrated power supply wires drawn from the notch hole 4 onto the base are in front. Two set screw through holes 7 are formed on both sides of the center.

  In addition, two blade receiving holes 8 into which plug blades are inserted are formed in the center of the base protection lid 3, and a set screw through hole 9 is formed in the vicinity thereof. A set screw 11 is inserted into the set screw through hole 9.

  The set screw 11 is fastened to a female screw of a screw seat (not shown) that protrudes at a position corresponding to the set screw through hole 9 of the base protective cover 3 of the base 2, so that the base protective cover 3 Is fixed to the base 2.

  On the base 2 covered with the base protection lid 3, although not particularly shown, two blade receiving portions each provided with electrode wire connection terminals are provided on the base protection lid 3. It is erected at a position corresponding to the blade receiving hole 8.

  When this outlet is attached to a place where the device mounting rail of the control panel is not attached, first, the set screw 11 is loosened and extracted, and the base protection lid 3 is removed from the base 2. Next, in a state where the base 2 is pressed to an appropriate position on the inner panel of the control panel, a hole is drilled from the front side of the base 2 (with a shape that is slightly shortened as a set tool with a flat head screwdriver and a flat head screwdriver). A tool) is inserted into the set screw through-hole 7, and the mark on the inner plate of the control panel is marked (also referred to as an injury).

  Subsequently, these members are set aside, and a hole is drilled at the place of the mark just made. Here, the method is divided into two. One method uses a cutting blade tool to cut the female thread into the fool hole. One other method leaves the fool holes open.

  Next is the same work. That is, the tip of the power supply wire is branched into two electrode wires, and only the covering is removed, and the contents of the conductive wires are stripped naked. Subsequently, these two conducting wires are respectively drawn through the branch wiring drawing hole 6 and onto the base 2 and connected to the electrode wire connecting terminals of the two blade receiving portions, respectively.

  The following work follows the above two methods. That is, when the female screw is cut in the fool hole, the base 2 is pressed to the same position as when the mark on the inner plate of the control panel is scratched. The set screw through hole 7 is aligned with the female screw hole cut earlier, and the set screw is tightened into the female screw hole with a screwdriver through the set screw through hole 7. Thus, the base 2 is fixed to the control panel inner plate.

  If the hole is left open, the base 2 is pressed to the same position as above, and a long bolt is passed through the set screw through hole 7 and the hole. A nut is screwed onto the bolt tip that comes out, the rotation of the bolt is suppressed with the fingertip of one hand turned to the back side of the inner panel of the control panel, and the bolt is tightened to the nut with the wrench held on the other hand. Thus, the base 2 is fixed to the control panel inner plate.

Then, the removed base protection cover 3 is put on the base 2 again, the removed set screw 11 is again inserted into the set screw through hole 9, and the set screw 11 is screwed into the internal screw seat with a Phillips screwdriver. The base protection lid 3 is fixed to the base 2 again. Thus, the outlet 1 can supply commercial power via a plug to the portable computer for maintenance work.

By the way, the outlet 1 is provided with a rail mounting portion that can be fitted and locked to the rail in the panel on the outer surface on the back side of the base 22.

  3 (a) is a perspective view showing the configuration of the rail mounting portion, FIG. 3 (b) is a partial perspective view of the outlet 1 of FIG. 1 (a) viewed from the front side, and FIG. It is a figure which shows the state which attached the electrical outlet to the rail in a panel by the rail attaching part.

  In FIG. 3 (a), the same components as in FIGS. 1 and 2 are given the same reference numerals as in FIGS. 1 and 2, and FIGS. 3 (b) and 3 (c) are used for explanation. The numbering is omitted except for the necessary components. 3 (a), (b), and (c), the diagonally lower right direction of FIG. 2 is shown upward, and the diagonally upper left direction of FIG. 2 is shown downward.

As shown in FIG. 3 (a), on the outer surface of the back side of the base 22 of the outlet 1, a groove portion 41, which is only numbered in FIGS. Is formed.
In this groove portion 41, a fixed mold arranged to be engaged with one side portion (upper portion in FIG. 3 (c)) of the in-board rail 42 fitted into the groove portion 41 as shown in FIG. 3 (c). A claw portion 43 and a slide-type claw portion 44 arranged to be engaged with the other side portion (the lower side portion in FIG. 3C) of the in-board rail 42 are also provided. These groove portion 41, fixed claw portion 43 and sliding claw portion 44 constitute a rail attachment portion.

Further, the sliding claw portion 44 is fitted into a claw engagement groove 45 which is formed in two upper and lower portions below the groove portion 41 on the back surface of the base 22. The urging member 46 is interposed between the base 22 and the fixed claw portion 43 at the engaging portion with the upper claw engaging groove 45.

  Thus, the sliding claw portion 44 is always urged by the urging member 46 in the direction of the locking position with the in-panel rail 42. In this biased state, the sliding claw portion 44 is positioned by the lower claw engaging groove 45.

  Further, the sliding claw portion 44 resists the urging force of the urging member 46 by an external force, and is in a direction opposite to the locking position direction with respect to the rail 42 in the panel (examples shown in FIGS. 3A and 3C). Is configured to be slidable downward).

  The above external force is obtained by inserting the tip of an appropriately sized flat screwdriver into the hooking hole 47 formed at the lower end on the front side of the sliding claw 44 shown in FIG. With the lower end of the front face as the fulcrum of the lever, the handle of the screwdriver is gently lifted upward to slide the sliding claw 44 downward, and the upper claw is engaged with the rail 42 in the panel. Can be released from the match.

In this state, the outlet 1 can be easily detached from the in-panel rail 42 by lifting the whole while pulling the lower part of the outlet 1 forward.
There are two methods for attaching the outlet 1 to the in-panel rail 42. One is to fit a groove 41 shown in FIG. 4A from the open end of the rail 42 in the panel as indicated by an arrow a in FIG.

  In another method, the upper fixed claw portion 43 is first hooked on the upper portion of the in-panel rail 42, and then the lower portion of the outlet 1 is connected to the in-panel rail 42 as shown by the arrow b in FIG. Press from the front.

  Thereby, since the inclined surface 48 is formed in the upper claw portion of the sliding claw portion 44, the inclined surface 48 slides on the lower side portion of the inner rail 42, and the urging force of the urging member 46 is applied. The lower part of the inner rail 42 is inserted into the groove 41. Therefore, since there is no object blocking the claw part of the sliding claw part 44, the sliding claw part 44 is raised by the urging force of the urging member 46, and the claw part is locked to the rail 42 in the board.

  Note that the urging member 46 is a push-urging spiral spring in the example shown in FIG. 5A, but the urging member 46 is not limited to this, and may be a leaf spring, for example, a torsion spring. A wirework spring or the like may be used.

  However, it goes without saying that the shape and configuration of the engagement portion between the sliding claw portion 44 and the claw engagement groove 45 should be changed according to the type of the spring.

  FIG. 4 is a perspective view showing another configuration example of the rail mounting portion of the outlet according to the second embodiment.
