Prefabricated Distribution Board {FABRICATED CABINET PANEL}

The present invention relates to an industrial prefabricated distribution panel used in factories, large buildings, large residential areas, etc. More specifically, the assembly of the busbar busbar and the branch-connected case can be simply assembled in a mutual fastening method without the need for a separate connection element. It relates to a prefabricated distribution board made to be.

In general, the assembled terminal board of the conventional terminal method is a bus bus bar (2) in the electrical connection between the bus bar (2), the bus bar (2) used and the branch connector 5, as illustrated in Figs. It is understood that R), S phase, T phase, N phase and the like are vertically arranged, and are connected to the bus busbar 2 using a terminal connector 5 of the terminal method.

As shown in FIG. 2, the branch connector 5 is formed in a bent form connected to the branch breaker 4 so as to be directly fastened by a terminal method on the side of the bus bar 2 arranged vertically. And the parts are branch connectors formed in the shape of "E" with a flame-retardant insulation which is wrapped, an upper terminal 11 coupled by a bolt to an upper end of the connector 14, and an end plate coupled with the branch connector 5. It consists of an end plate 13 and a color cap 9.

End plate (End Plate) after selecting the phase to be connected to the end of the branch connector 5, the upper terminal 11 and the connector 14 is completely sealed and insulated, the end plate 13 and the branch connector ( When 5) is fastened using the assembly bolt 10, the selected phase connector is bundled into one product.

On the other hand, the connector 14 can be selectively assembled to adjust the phase equilibrium because the connector shape of each phase is made so that only the necessary phase can be selected and fastened. (Example: Assemble single-phase breaker in R-N / S-N / T-N type)

And, an upper cap (Color Cap) having a color (9) in the upper portion to distinguish each phase. (R phase-black / S phase-red / T phase-blue / N phase-white / other-yellow)

Branch connector is made of “E” shaped flame retardant insulation to prevent fire accident and short circuit between phases and completely cover busbar busbar 2 and connector 14 to prevent electric shock or ground fault from foreign objects. Prevents.

In addition, it is possible to identify which phase is connected by inserting the upper and lower caps 9 whose colors are distinguished for each phase into the holes in the upper portion of the branch connector 5.

However, the branch connector 5 in such a prefabricated distribution board has a branch connector formed in the shape of an "E" shape with a flame-retardant insulator enclosing the parts, and a terminal method at the side of the bus bar 2 arranged vertically. The bolt 14 is formed of a bent connector 14 connected to the branch breaker 4 so as to be directly fastened, and an upper terminal 11 coupled to the upper end of the connector 14 by a bolt. A problem such as the loosening of the clamping force occurred, the electrical connection efficiency is lowered, and the reliability is lost.

The present invention was developed in order to solve the above problems, the object of the electric bolt is always at the same time by adopting the two-way elastic connecting means to electrically connect the busbar busbar and the connector by the elastic clipping tightening method to escape the conventional bolt fastening method It is to provide a prefabricated distribution panel to maintain the proper connection performance.

The present invention was developed to achieve the above object, the present invention, in the prefabricated distribution panel for electrically connecting to an electrical element such as a circuit breaker in a plurality of busbar modules arranged in parallel at a predetermined distance,

Formed in a shape having a plurality of connection ports open to one side with a flame-retardant insulator so that the busbar module can be inserted, a plurality of parallel arrangement branch connection type having a plurality of chambers partitioned into a predetermined space by a plurality of walls With the case,

A plurality of connectors inserted into the branched case so as to protrude from both sides of the branched case;

A first fastener for interconnecting one phase of the busbar bus bar and a second fastener formed to face the first fastener so as to be connected to one of the plurality of connectors protruding to be connected to the branch breaker primary side are elastically connected. And an elastic clamp adapted to engage the interconnect coupling function.

As described above, the present invention improves the economic efficiency by improving the reliability at the time of electrical connection. This is achieved by using an elastic clamp formed with a two-way fastener to maintain a state of elastic tightening force at all times in order to prevent the possibility of non-energization caused by the loosening of the bolt by repeated connection that may appear at the terminal clamping part. There is a very good effect such as to be able to maximize.

As described above, the present invention provides an elastic tightening force at all times in order to improve the economic efficiency by improving the reliability at the time of electrical connection, and to block the possibility of non-electrical generation by releasing the bolt by repeated connection that may appear at the terminal clamping part. By using the elastic clamp to keep the busbar bar and the connector in such a state, it is possible to simplify the assembly and to maximize the long-term power supply efficiency.

In the distribution panel according to the present invention, the case may be provided with a phase-division display on the front surface so as to distinguish between R phase, S phase, T phase and N phase neutral phase (pole) for three-phase (pole) alternating current. In order to provide a separate branch connection mechanism in the busbar bus bar, the work is easy and erroneous connection is minimized, thereby improving work productivity and reliability during manufacturing and installation, and requiring skilled workers to obtain unnecessary effects.

In the distribution panel according to the present invention, busbar bars are structured by being stacked with electrical insulation intervals in the vertical direction, so that the horizontal size of the distribution boards can be reduced compared to the horizontal arrangement of the busbar bars. have.

In the distribution panel according to the present invention, the branch busbar and the clip connector are simply connected and assembled by the bolt and the elastic clamp, and the contact pressure and the contact area can be effectively maintained, thereby increasing the electrical connection efficiency.

In the distribution panel according to the present invention, since it is stably elastically supported by the branch contact spring, the contact force is reliably maintained when the bus bus bar contacts, thereby preventing the instability of the energizing current and the heat generation phenomenon due to the contact failure.
