The spring 152 is fixed to the shaft portion 151a of the support shaft 151 to elastically support the movement of the slider 130.

The fitting portion 120 includes a support plate 122 forming an upright cross-section on the opposite surface of the base frame 110, a locking end 121 that is bent downward from an upper side (or one side) of the support plate 122, and a support plate 122 ), including a fitting groove 123 into which the upper end 11 of the DIN rail 10 is fitted, and an insertion hole 124 in which the elastic part 150 is coupled at the end of the support plate 122 do.

The support plate 122 is supported by a support wall 112 that protrudes and extends from the opposite surface of the base frame 110 and is formed to extend in one direction.

The locking end 121 is bent at the support plate 122 to form a fitting groove 123 into which the upper end 11 of the DIN rail 10 is fitted. 3 and 4, the locking end 121 extends a certain length forward from the upper side of the extension plate 134 and is bent downward. A fitting groove 123 into which the bent top 11 can be inserted is formed.

One or more insertion holes 124 are formed inwardly at the end 122a of the support plate 122 so that the end of the support shaft 151 can be inserted.

The sliding groove 140 guides the movement of the slider 130 as a spaced apart space between the support plate 122 and the base frame 110.

The slider 130 has a slide plate 131 that protrudes and moves along the sliding groove 140, and an end pressing surface 132 that is bent at the slide plate 131 to which the end 122a of the support plate 122 is coupled. , The pressure protrusion 133 pressed by the lower end 12 of the DIN rail 10, the extension plate 134 extending downward from the pressure protrusion 133, and the shaft portion of the elastic part 150 ( It includes a through hole 135 through which 151a) passes, and a guide protrusion 131b for preventing a gap between the lower surface of the slide plate 131 and the sliding groove 140.

The slide plate 131 is formed in a plate shape extending from the lower end 12 of the end pressing surface 132 toward the sliding groove 140. That is, the slide plate 131 is moved along the sliding groove 140 by an elastic force. Here, the slide plate 131 may include a fitting protrusion 131a protruding rearward and a guide protrusion 131b protruding downward from both sides of the lower surface.

The fitting protrusion 131a protrudes from the rear wall surface (ie, the wall surface of the end pressing surface 132) of the slide plate 131 and is fitted to the stopper.

The guide jaw 131b is a pair of slide plates 131 spaced apart from each other and protrudes downward and extends in the front-rear direction. Here, the guide jaw 131b protrudes downward from both sides of the lower surface of the slide plate 131 and is adjacent to the side of the sliding groove. Accordingly, the guide jaw 131b guides the slide plate 131 while shielding the gap between the slide plate 131 and the sliding groove 140.

Therefore, the slide plate 131 can be moved without opening a gap between the sliding grooves 140 according to the shielding guidance of the guide protrusion 131b, so that it can be separated from the sliding groove 140 or be protected from the phenomenon of being trapped by foreign substances. have.

The pressing protrusion 133 is formed as an upward or downward locking protrusion 133a to transmit the pressure applied while being in close contact with the lower end 12 of the DIN rail 10 and to engage the lower end of the DIN rail. Perform. That is, the upward locking protrusion 133a of the pressing protrusion 133 forms an inclined surface so that the lower end can be latched and guided from one side, and forms an upright surface on the opposite surface bent from the wall surface of the end pressing surface 132 to form an end pressing surface ( 132).

Therefore, the lower end 12 of the din rail 10 presses the locking protrusion 133a of the pressing protrusion 133, and the slider 130 is pressed by the lower end of the din rail 10 by the pressure received by the locking protrusion. It is moved to the opposite side to form a space spaced between the end of the support plate 122 and the end pressing surface 132.

Therefore, the lower end 12 is guided along the inclined surface of the locking protrusion 133a and is inserted between the spaced space between the end of the support plate 122 and the end pressing surface 132 and is caught in the erect stepped jaw.

The end pressing surface 132 is formed as a wall surface extending horizontally between the slide plate 131 and the pressing protrusion 133, so that the slider 130 is the support plate 122 when it is returned to its original position by the elastic force of the elastic portion 150. To accommodate the end (122a) of.

At least one through hole 135 is formed through the wall surface forming the end pressing surface 132. Here, the through hole 135 guides the support shaft 151, but the diameter may be adjusted so that the spring 152 can be engaged.

The extension plate 134 extends downward from the pressure protrusion 133 to support the pressure applied to the pressure protrusion 133, but forms a space spaced between the base frame 110 and an elastic part positioned therebetween. Protect 150 from being exposed to the outside. In addition, the extension plate 134 may serve as a handle capable of moving the slider 130 by pulling by an operator by hand in order to release the coupling between the DIN rail 10 and the bracket 100.

The stopper 160 protrudes from the base frame 110 to prevent the slider 130 from moving. Specifically, the stopper 160, for example, as shown in Figure 4, the horizontal plane 161 extending from the opposite surface of the upright base frame 110 and the bent upward in the horizontal plane 161 It is formed in a'b' shape including the stage 162. The horizontal surface 161 and the bent end 162 allow the fitting protrusion 131a protruding from the wall surface forming the end pressing surface 132 of the slider 130 to be fitted.

That is, the stopper 160 may be formed to engage the rear surface of the end pressing surface 132 of the slider 130 or the fitting protrusion 131a protruding in the opposite direction to the slide plate 131.

In addition, the elastic portion 150 is located between the extension plate 134 and the bent surface. Accordingly, the bent surface of the stopper 160 may support the support shaft 151 from an impact applied through the extension plate 134.

According to the present invention, as the configurations described above are provided, mounting on the DIN rail 10 can be made very easily, which will be described with reference to FIGS. 5 to 7.

5 to 7 are views sequentially showing a process of mounting the bracket 100 according to the present invention to a DIN rail.

5, first, the bracket 100 is fixed to the rear surface of the object 20 by a fixing means 200 for inserting the fixing hole 111 of the base frame 110 in communication, and the slider 130 is a slide The plate 131 is supported by the elastic force of the spring 152 installed on the outer surface of the support shaft 151 while the plate 131 is fastened to the sliding groove 140.

In addition, the pressing protrusion 133 maintains a state spaced apart from the engaging end 121 at a position facing the upper and lower sides, and the end of the support plate 122 is in a state accommodated in the end pressing surface 132 of the slider 130 .

As described above, the operator moves the bracket 100 to the fixed wall surface of the DIN rail 10 in an upright position so that the locking end 121 is positioned at the upper side and the pressing protrusion 133 is positioned at the lower side. Thereafter, as shown in FIG. 5, the operator holds the upper end 11 of the DIN rail 10 inclined and lowers it. Accordingly, the upper end 11 of the DIN rail 10 fixed to the wall surface is fitted into the fitting groove 123 formed at the lower side of the locking end 121.

And the operator, as shown in Figure 6, the lower side of the bracket 100 so that the lower end 12 of the DIN rail 10 is fitted to the lower end 12 of the pressing protrusion 133, the lower side of the bracket 100 Rotate to the lower end (12) side of DIN RAIL) (10). Therefore, the lower end 12 is in close contact with the locking projection (133a) of the pressing protrusion (133).

At this time, the lower end 12 of the DIN rail 10 presses the locking protrusion 133a of the pressing protrusion 133. And the slider 130 is lowered by the pressure applied while the lower end 12 is in close contact with the locking projection (133a).

That is, referring to FIG. 7, the slide plate 131 of the slider 130 descends through the sliding groove 140 when a downward pressure is applied through the pressing protrusion 131, and forms the end pressing surface 132. The wall surface compresses the spring 152 while moving along the support shaft 151.

Therefore, the lower end 12 of the DIN rail 10 passes through the locking protrusion 133a of the pressing protrusion 133 and is inserted into the end pressing surface 132 and is locked. At this time, the pressure applied to the spring 152 is released as soon as the lower end 12 is inserted into the end pressing surface 132. Therefore, the spring 152 presses the slider 130 while being restored to its original shape. Therefore, the slider 130 returns to its original position.

Alternatively, in the separation of the object 20, when the operator holds the extension plate 134 of the slider 130 and descends, the slider 130 descends and compresses the spring 152. Therefore, as the position of the pressing protrusion 133 is lowered, the locking state of the lower end 12 of the DIN rail 10 is released.

Here, in the slide plate 131, a guide jaw 131b protruding downward from the lower surface is moved along the side end of the sliding groove 140. Therefore, a gap between the sliding groove 140 and the lower surface of the slide plate 131 is prevented by the guide jaw 131b.

And when the operator grabs the bracket 100 and/or the object 20 and rotates it to the outside and then lifts it upward, the top and bottom 12 of the DIN rail 10 press the fitting groove 123 and the end. It can be withdrawn from the surface 132.

In summary, in the present invention, when the operator first inserts the upper end 11 of the DIN rail 10 and then presses and rotates the lower end 12 of the bracket 100, the DIN rail 10 As the slider 130 is lowered by the pressure of the lower end 12, the lower end 12 is automatically fastened.

The fastening method of the DIN rail 10 using the slider 130 may shorten the working time of the operator and reduce the physical force, thereby improving workability.

Those of ordinary skill in the technical field related to the present embodiment will appreciate that it may be implemented in a modified form within a range not departing from the essential characteristics of the above-described substrate. Therefore, the methods of disclosure should be considered from an explanatory point of view rather than a limiting point of view. The scope of the present invention is shown in the claims rather than the above description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
