The case may include a first case 110 and a second case 120 so as to be disassembled, and may include a side cover that is detachably provided in the side direction.

The side cover may include a first side cover 130 and a second side cover 140.

When the first case 110 and the second case 120 are assembled, the first supply connector 200, the second supply connector 300 (310), and the third supply connector 400 can be provided therein. and may be provided to protrude from one side of the case.

One or more primary supply connectors 200 may be provided, and may be variably provided as one or more depending on the power supply capacity. The primary supply connector 120 is connected to a busbar so that external power can be supplied.

The secondary supply connector 300 can supply power to each power device by branching the external power supplied from the primary supply connector 200.

The multi-connector module 100 is supplied with a separate external power source through the tertiary supply connector 400, and supplies power to a storage unit provided in a plurality of drawers in the MCC (Motor Control Center) main body and various indicator lights provided in the MCC main body. We can supply it.

The second case 120 contains a primary connection port 510, a secondary connection port 520, and a tertiary connection port 530 that store various electrical devices such as circuit breakers and are connected to storage units that enter and exit the MCC. can be formed.

Referring to FIG. 9, the primary connection port 510 and the secondary connection port 520 can be provided by injection molding, and a plurality of connection holes 511 and 521 are formed, and the connection holes 511 and 521 are formed. Frames 512 and 522 are formed to protrude around the circumference, and the plurality of connection holes 511 and 521 are spaced apart at intervals, and thus, the plurality of connection holes 511 and 521 are formed to be spaced apart from each other. Guide paths 513 and 523 may be formed between the .

A power cable is inserted into the assembled first case 110 and the second case 120, and the built-in power cable is formed on the side of the first case 110 and the second case 120. The power cable is drawn out through the first outlet hole 131 and/or the second outlet hole 132, and the power cable is connected to a plurality of guides formed in the primary connection port 510 and the secondary connection port 520 (513) (523). ) can be drawn out to the outside through the first outlet hole 131 and/or the second outlet hole 132.

Accordingly, the power cable drawn out of the case can maintain straightness without being bent inside the case, and thus the generation of electrical resistance heat due to bending of the power cable can be prevented.

In an embodiment of the present invention, the primary connection port 510 and the secondary connection port 520 may be formed with four connection holes 511 and 521, and each of the R, S, T lines and the neutral line having different phase differences may be formed. The N line can be connected. If necessary, connect only the R, S, and T lines, and the N line may not be used depending on the type.

Therefore, in the present invention, the blocking member 150 can be detachably coupled to the second case 120 corresponding to the connection holes 511 and 512 used for N-line connection.

The second case 120 has a first through hole 121, a second through hole 122, and a third through hole through which the first connection port 510, the second connection port 520, and the third connection port 530 are coupled. Each ball 123 may be formed.

The blocking member 150 forms the fitting protrusion 151 to protrude, and penetrates the first through hole 121 and the second through hole 122 formed in the second case 120 to form the primary connection port 510 and the second through hole 122. The N line formed in the secondary connection port 520 may be detachably coupled to the connection holes 511 and 521 to which it is connected.

The first case 110 has a primary through hole 111 through which the primary supply connector 200 protrudes, and a plurality of secondary through holes 112 through which the primary supply connector 300 protrudes (112a). ) and a tertiary through hole 113 through which the tertiary supply connector 400 protrudes may be formed.

A plurality of outlet holes may be formed in the first side cover 130, and in an embodiment of the present invention, a first outlet hole 131 and a second outlet hole 132 may be formed.

Additionally, a cutout portion 131a may be formed in a portion of the first outlet hole 131 of the first side cover 130. The first outlet hole 131 may not be completely closed but may have an opening formed by the incision 131a.

The cut portion 131a can eliminate the inconvenience of pulling out the power cable through a narrow hole when drawing out the power cable through the first outlet hole 131. That is, if the power cable is inserted from the side through the cut portion 131a, it can be easily inserted into the first outlet hole 131.

The power cable drawn out through the first outlet hole 131 may be thicker than the power cable drawn out through the second outlet hole 132, so it may not be easy to handle. Therefore, since it is not easy to penetrate the first outlet hole 131, it can be more easily inserted by inserting a thick power cable from the side of the first outlet hole 131.

Accordingly, the power cable passing through the second outlet hole 132 has a thinner thickness and can easily pass through the second outlet hole 132.

Insulating members may be provided in the first outlet hole 131 and the second outlet hole 132 of the first side cover 130, respectively. That is, the first insulating member 133 may be fitted into the first outlet hole 131, and the second insulating member 134 may be fitted into the second outlet hole 132.

The first insulating member 133 and the second insulating member 134 may each have passing holes 133a and 134a formed through which a power cable can pass.

The first insulating member 133 and the second insulating member 134 prevent damage caused by contact when the power cable drawn out through the first outlet hole 131 and the second outlet hole 132 contacts. At the same time, it can exert an insulation function to prevent electrical shorts.

Since the power cable is an electrically conductive wire, it is possible to prevent in advance the phenomenon of the first insulating member 133 and the second insulating member 134 being peeled off and conducting electricity to the first side cover 130, thereby reducing the electrical Safety accidents can be prevented.

The first outlet hole 131 may be formed to be longer in the vertical direction in the drawing than the second outlet hole 132, and therefore, the first insulating member 133 is longer than the second insulating member 134. It may have a formed length, and the first insulating member 133 may have a structure in which a cut portion 133a is formed in which a portion of the first insulating member 133 is cut. The second insulating member 134 may have a structure without any cut portions.

Since the power cable in contact with the first insulating member 133 has a thick structure, this power cable is inserted into the first outlet hole 131 through the cut part 131a, and the cut part of the first insulating member 133 is inserted into the first outlet hole 131. The power cable can be easily inserted or separated using (133a), and the first insulating member 133 inserted into the power cable can be assembled by inserting it into the edge of the first outlet hole 131 of the first side cover 130. You can.

Protective covers 160 may be removably provided in the secondary through-holes 112 and 112a formed in the first case 110, respectively.

The protective cover 160 may have a structure having three sides to surround the secondary supply connectors 300 and 310 protruding through the secondary through holes 112 and 112a. Specifically, the protective cover 160 may have a first side 161, a second side 162, and a third side 163, and may have an opening 164 formed therein.

The first surface 161 of the protective cover 160 forms the upper surface, and the second surface 162 and the third surface 163 extend in orthogonal directions from both ends of the first surface 161, respectively. It can be done on the side. One or more locking holes 161a may be formed on the first surface 161 forming the upper surface, and one or more locking pieces 114 may be formed to protrude at corresponding positions of the first case 110.

The protective cover 160 is transparent or opaque and can be made of, for example, acrylic material.

This protective cover 160 can protect the protruding secondary supply connectors 300 and 310. In other words, the secondary supply connectors 300 and 310 have a structure in which the connecting conductors 301 and 311 protrude from the connecting ports 302 and 312, so that work tools or various items fall and collide during repair work, etc. In this case, damage or an electrical safety accident may occur, and therefore, if the protective cover 160 is wrapped on the outside, it can protect the secondary supply connectors 300 and 310 from such safety accidents.

The connecting conductors 301 and 311 of the secondary supply connectors 300 and 310 may be provided in plurality, and when arranged in plurality, two are arranged in the vertical direction to prevent insulation and unexpected contact between them. A diaphragm 320 may be provided to prevent this.

An electric wire (E) is connected to the connecting conductors (301) (311). When connecting the electric wire (E), a bolt (305) is inserted into the coupling hole (304) formed in the connecting conductors (301) (311), and the bolt (305) is connected to the connecting conductor (301) (311). It can be assembled by inserting a crimp terminal formed at the end of the electric wire (E) between the head portion of (305) and the connecting conductors (301) (311). At this time, since the bolt 305 must be combined with the nut 306 and tightened, a seating member 308 connected to the connection ports 302 and 312 is provided at the lower part of the connecting conductors 301 and 311, and the seating member 308 ) A seating groove (308a) is formed inside the seating groove (308a), and the nut (306) can be inserted into the seating groove (308a) and then the bolt (305) can be coupled.

Referring to FIG. 8, connecting pieces 308b may be formed to extend on both sides of the seating member 308, and a locking protrusion 308c may be formed to protrude from an end of the connecting piece 308b.

The seating member 308 can be detachably coupled to the connection ports 302 and 313 through connection pieces 308b, and locking protrusions 308c are inserted into both sides of the connection ports 302 and 313 to enable locking. It may have a structure in which a locking groove 314 is formed to do so.

Since the nut 306 is previously inserted into the seating groove 308a of the seating member 308, when connecting the electric wire E, the bolt 305 is connected to the coupling hole 304 formed in the connecting conductor 301 (311). It can be connected to the nut 306 at the bottom of the nut 306, and the nut 306 has an angled shape, and the seating groove 308a is also made of an angled groove to match it, so it does not spin around in the seating groove 308a. It can be maintained in a fixed state, and can be easily combined by turning only the bolt (305). Accordingly, the work of connecting the wires (E) can be performed very easily, and the work time of connecting the wires can be significantly reduced.

If the nut 306 is not inserted into the seating member 308 as in the present invention, but is separately combined with the bolt 305, it may take a lot of work time.

The worker holds the nut 306, which is relatively small in size, with one hand and tightens the bolt 305 with the other hand using a power tool, etc., while inserting the crimp terminal of the wire E into the bolt 305. When combining, the nut 306 may be missed due to carelessness, and then it may be difficult to find the nut 306 again, and work may have to be done with another nut 306 provided in advance. Therefore, in situations where a lot of assembly is required, work time can significantly increase and efficiency can decrease. However, in the present invention, the nut 306 is inserted into the seating groove 308a of the seating member 308 in advance, and the bolt 305 is passed through the connecting conductors 301 and 311 without losing the nut 306. It can be easily combined with the nut (306).

In particular, when the working space of the workshop is narrow, connecting wires may be more difficult when the bolt, wire, and nut combination method is common. However, the present invention can perform the work quickly and accurately even in such a narrow place. Because this work time is shortened and a large number of wires can be connected, the overall manufacturing cost can be lowered.

Additionally, a safety cover 410 may be detachably coupled to the lower or upper portion of the tertiary connector 400. The safety cover 410 includes a protective plate 411 that prevents falling objects, a connecting piece 412 extending from both ends of the protective plate 411, and a coupling protrusion 413 protruding from the inner surface of the end side of the connecting piece 412. ) may include.

The ends of the secondary connection busbar 630 may be bent and coupled through the primary connection port 510 and the secondary connection port 520, respectively.

Of course, the second support plate 620 includes a plurality of supports 631 that support a plurality of secondary connection busbars 630. Passing holes 632 and 633 through which the bent end of the secondary connection busbar 630 protrudes may be formed.

When assembling the first case 110 and the second case 120, as a means for easier assembly, a post guide member 170 is attached to either the first case 110 or the second case 120. Can be combined.

A coupling hole 171 may be formed in the post guide member 170, and a fastening member such as a screw may be coupled to the coupling hole 171 from the first case 110 and the second case 120, respectively. The coupling hole 171 may have a structure other than a threaded hole, and when the fastening member is coupled while rotating on both sides of the coupling hole 171, the coupling hole 171 may be screwed to the fastening member while threads are formed.

In other words, the first screw 181, which is a fastening member, can be coupled from the first case 110 side through the coupling hole 171, and the second screw 182, which is a fastening member, can be coupled from the second case 120 side. there is.

The outer peripheral surface of the post guide member 170 may be formed in an angled shape to enable secure grip during assembly.

Since the post guide member 170 has a structure that protrudes from the first case 110 or the second case 120, it can guide the first case 110 and the second case 120 when they are combined. That is, when the post guide member 170 is coupled to the upper and/or lower inner surface of the second case 120, when assembling the first case 110 to the second case 120, the protruding post guide member ( The first case 110 can be coupled to the second case 120 while facing the upper surface of 170, and therefore, the first case 110 and the second case 120 can be coupled without shaking during assembly. It can be done.

An assembly hole 115 for screwing the first screw 181 into the coupling hole 171 of the post guide member 170 may be formed in the first case 110.

Likewise, an assembly hole 125 for screwing the first screw 182 into the coupling hole 171 of the post guide member 170 may be formed in the second case 120.

On the other hand, when assembling the post guide member 170, the first screw 181 or the second screw 182 must be coupled while holding the outer peripheral surface of the post guide member 170 with a tool, etc., and conversely, when dismantled, Even while holding the outer peripheral surface of the post guide member 170 with a tool, etc., the first screw 181 or the second screw 182 must be loosened.

Therefore, in order to assemble or disassemble more efficiently, the present invention, as another embodiment, forms an extension piece 173 extending in a perpendicular direction (for example, downward direction) from one side of the post guide member 170, and extends the post guide member 170. A stop protrusion 174 may be formed to protrude on the end side of the piece 173.

The stop protrusion 174 can be formed in a circular or square shape, and when first assembled in the second case 120, the insertion hole 126 is formed in the second case 120, and then the stop protrusion 174 is inserted into the second case 120. It can be inserted and fixed. By doing this, when the post guide member 170 is coupled, the post guide member 170 can be maintained in a stopped state by the stop protrusion 174 even if the post guide member 170 is not held, so the operator can use the first screw ( 181) and the second screw 182 can be conveniently screwed together by inserting them through the assembly holes 115 and 125 formed in the first case 110 and the second case 120, respectively.

The stop protrusion 174 may be coupled to the first case 110 or the second case 120 to prevent the post guide member 170 from spinning when screwed.
