Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wiring box having a fixing device using an elastic force,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring box equipped with a fixing device using an elastic force.

In a wiring box used in wiring work, most wiring boxes are not directly attached to a ceiling or a floor, but are not provided with a fixing member, and are directly connected to the installation site using fixing means such as bolts.

However, since such a fixing means such as a bolt is required to be installed on the wall surface of the installation site or to install another installation member, not only the operation time is long, but also a separate member is required, .

In addition, there is a problem that it is difficult to attach to a structure to be installed separately at the installation site for wiring work.

Therefore, in the past, a technique has been proposed in which a fixing member, which is detachable to a structure previously installed in a wiring box, is provided.

However, although the above-described conventional techniques can be fixed to various structures using elastic force, they can be applied only to a round bar (for example, a reinforcing bar) having a small diameter. However, the structure in which the wiring box is fixed as described above can not be widely used for various bar-shaped structures such as, for example, M-shaped open top, C-open and T-shaped open.

Therefore, conventionally, there has been a problem that the construction is cumbersome and the cost is increased because a separate structure is added or the shape of the wiring box is modified depending on the shape of the supporting structure in which the wiring box is installed.

Here, the first spacing means 332 may include a washer for strengthening the fixing force between the guide plate 311 and the wiring box 100.

Alternatively, the first fixing means 331 and the first spacing means 332 may be applied with rivets. That is, in the present invention, the first fixture 330 can be applied to any structure in which the guide plate 311 can be fixed in a state of being separated from the outer surface of the wiring box 100.

The elastic part 320 is made of spring steel having an elastic force and is fastened through the slit 312 of the first guide part 310. A more detailed configuration will be described with reference to Fig.

4 is a front view showing the elastic part 320 in the present invention.

1 to 4, the elastic part 320 includes a head 321 slidably inserted between the first guide part 310 and the lower surface of the wiring box 100, And a pressing plate 322 for pressing the wall surface of the pressing plate 322 by an elastic force.

The head 321 is extended in one direction or both directions so as to slide between the lower surface of the wiring box 100 and the spaced space between the first guide portions 310. [

The pressure plate 322 extends in one direction from the head 321 and presses the other wall surface of the support 200 in the opposite direction to the support bent plate 313 described above.

That is, in the elastic part 320, the pressure plate 322 is inserted into any one of the slits 312 selected in accordance with the distance between both side walls of the support table 200. The head 321 is slid between the first guide part 310 and the lower surface of the wiring box 100. The pressing plate 322 presses the wall surface of the support table 200 with an elastic force as the head 321 is pulled through the open upper surface of the support table 200 in a state of being held in the outer peripheral surface of the slit 312.

Preferably, the pressure plate 322 may further include at least one friction protrusion (not shown) so as to generate a frictional force at an outer surface which is in close contact with the supporter 200.

The wiring box 100 is formed in a box shape that receives the connector portion 140 for branching the main wiring A drawn in one direction. A detailed description will be given with reference to Fig.

1 to 5, the wiring box 100 includes a main body 110 formed of wall surfaces erected at respective sides of a bottom plate and forming a space at an inner side thereof, a main wiring A connected to at least one branch wiring A wiring support portion 120 for fixing the main wiring A and / or the branch wiring B to the main body 110 and a second wiring fixing portion 120 for fixing the wiring supporting portion 120 Includes a fastener (130).

The main body 110 is closed at its upper portion by a cover (not shown) and is formed as an upright wall surface from each side of the bottom surface, thereby forming a space in which the connector portion 140 is accommodated.

The main body 110 includes a cutout 111 cut out from the wall surfaces so as to allow the main wiring A and the at least one branch wiring B to be drawn in and out and at least one fixing And a hole 112.

The number of the cutouts 111 varies depending on the number of the main wirings A and the branch wirings B drawn out to the main body 110. Here, the incision opening 111 is formed by cutting a wall surface of the main body 110 in a U-shape so that when a wiring tube (not shown) in the form of a metal corrugated tube such as an ACF is mounted, ) Can be fixed by using the concave portion of the corrugated tube. That is, the corrugated tube may be hooked on the end face of the incision opening 111 because the concave groove is formed on the surface of the corrugated tube. Therefore, when the wiring connected to the wiring box of the present invention is applied to a corrugated pipe, it is possible to prevent the connection state from being released even if an abnormal situation such as an external shock is generated.

The wire supporting portion 120 is characterized in that the diameter of the incision opening 111 is adjusted to correspond to the distance between the incision opening 111 and the wires A and B by the difference in diameter. That is, the wire supporting portion 120 is installed to prevent the flow tube, the diverging tube, and all other wires from being flowed or separated without a separate bush-shaped fixing connector or the like.

Thus, the wire supporting portion 120 is movably fixed to the wall surface so as to adjust the diameter of the cut- To this end, the wire support 120 includes at least one slot 121 cut in one direction.

The wire support 120 is fixed to the wall surface of the cutout 111 by the second fixture 130. Here, the second fastener 130 is inserted through the slot 121 and fastened to the fastening hole 112. At this time, the wire support part 120 is movable along the slot 121 when the second fastener 130 inserted through the slot 121 is not completely fixed but is simply fastened.

Therefore, if the diameter of the main wire A drawn through the cutout 111 is smaller than the diameter of the cutout 111, the wire support 120 moves to the cutout 111 side, And is in close contact with one side. Then, the wiring support portion is completely fixed at the current position by the second fixture 130.

The connector 140 includes a main wiring connection terminal 141 to which a plurality of electric wires drawn from the drawn-in main wiring A (for example, a cable) are connected, A connector 143, and a board 142 for supporting the main wiring connection terminal 141 and the branching connector 143.

The main wiring connection terminal 141 is electrically connected to the branching connector 143 through the substrate 142. [

The main wiring connection terminal 141 and the branching connector 143 are connected to the main wiring A through the substrate without removing the outer conductor of the electric wire drawn out from the main wiring A and the branch wiring B, (Not shown) that can be electrically connected between the branch wiring (B) and the branch wiring (B).

The non-dissipative connection connector (not shown) strips only the contoured corrugated outer jacket of the wiring box 100 from the mutually opposing faces of the wiring box 100, thereby making it possible to connect the wires.

For example, the non-dissipative wire connector is configured such that a blade provided so as to energize a connection terminal of the electric wire and the substrate 142 is intruded into the wire and closely attached to the wire. Therefore, the electric wire drawn out from the main wiring A and the electric wire drawn out from the branch wiring B are connected to be energized with the substrate.

Therefore, the wiring box of the present invention further includes the non-dissipative connection connector, so that the wiring operation can be facilitated.

The first embodiment of the present invention includes the above-described structure. Hereinafter, the process of fixing the wiring box 100 to the support table 200 will be described. The M-type support table 200) is applied will be described first.

First, the worker inserts and fixes the first fastener 330 on the lower surface of the wiring box 100 into the fastening hole 314 of the first guide part 310. At this time, the operator places the first spacing means 332 between the lower surface of the first guide portion 310 and the lower surface.

The operator fixes the first guide part 310 to the lower surface of the wiring box by connecting the first fixing part 330 with the fastening hole 314 and the first spacing part 332. Accordingly, the first guide part 310 is fixed in a state of being separated from the lower surface of the wiring box 100 by the first spacing means 332.

Then, the operator confirms the distance between both side walls of the support table 200 (for example, the distance between the both side ends 220 of the support table 200 in Fig. 2). The operator selects any one of a plurality of slits 312 so that the distance between the support bending plate 313 and the elastic portion 320 is longer than the distance between both side walls of the support 200.

The operator inserts the elastic part 320 into the selected slit 312 to slide the head 321 between the lower surface of the wiring box 100 and the first guide part 310 to move the pressure plate 322 to a predetermined position.

The operator presses the pressing plate 322 and the supporting bending plate 313 through the opened upper surface of the supporting table 200 when the pressing plate 322 and the supporting bending plate 313 are positioned to face each other. Therefore, the pressure plate 322 and the support bending plate 313 are fixedly attached to both side walls (or both ends 210) of the support table 200, respectively.

Here, since the pressure plate 322 and the support bending plate 313 are provided with a plurality of friction protrusions, respectively, the frictional force can be increased and the binding force can be doubled.

In addition, the present invention is characterized in that, in addition to the M-type support table 200 having the top surface opened, the C-type support table 200 'and the T-shaped support table 200' Lt; / RTI > This will be described with reference to FIG. 6 and FIG.

6 is a view showing an example in which a wiring box equipped with a fixing device using an elastic force according to the present invention is fastened to a C type support.

Therefore, the pressure plate 322 is formed in a plurality of slits 312 so that the distance between the pressure plate 322 and the support bent plate 313 is longer than the gap between the upper and lower ends of the C-shaped support base 200 ' And is fastened to any one selected.

That is, the pressure plate 322 and the support bend plate 313 are assembled so as to have a longer distance than the length between the upper end and the lower end of the open side of the C-shaped support base 200, It is forced on the side.

7 is a view showing an example in which a wiring box equipped with a fixing device using an elastic force according to the present invention is fastened to a T-shaped support 200.

Referring to Fig. 7, the T-shaped support 200 '' is composed of a standing plate 202 standing upright at the lower center of the flat upper plate 201. Therefore, the present invention can be fixed by closely contacting the support bending plate 313 to one side of the upper plate 201 and the other side of the upper plate 201 with the pressure plate 322.

To this end, the gap between the pressure plate 322 and the support bending plate 313 is set to be shorter than the distance from one side of the upper plate 201 to the other side. That is, the pressing plate 322 and the supporting bent plate 313 are formed to be spaced from each other by less than the length of the upper plate 201, and fixed to both sides of the upper plate 201, respectively.

As described above, the present invention does not require a separate configuration depending on the shape and size of the supports 200, 200 ', 200' ', and thus can be used for general purposes.

In addition, the present invention can be applied to various supports 200 by using elastic springs 430 in the first embodiment using the first guide part 310 and the elastic part 320 having elasticity as described above But may further include other embodiments. This will be described below with reference to Figs. 8 to 10 attached hereto.

Other embodiments of the present invention include the above configuration, and the operation of another embodiment will be described below with reference to the accompanying drawings. Another embodiment of the present invention is described using an M-type support 200 having an opened top, but the present invention is not limited to this, but a C-type support 200 'having the open side described above and a T- 200 ").

FIG. 10 is a view showing a state of being fastened to a support of another embodiment of the present invention. FIG.

10, a worker stacks a sliding plate 421 on an upper surface of a fixed guide plate 411 and attaches a first supporting rod 413 and a second supporting rod 422 to a fixed bent plate 412 and a moving bent plate 422, Respectively. At this time, the elastic spring 430 is positioned between the fixed bending plate 412 and the movable bending plate 412.

The elastic spring 430 is fastened to the threaded rods 413b and 423b of the first and second support rods 413 and 423 on both sides.

Further, the fixed bending plate 412 and the movable bending plate 422 are fixed at mutually facing positions.
