Description

  The present invention relates to a charging unit configured by connecting a main copper bar and a branched copper bar in a distribution board in which electric devices such as breakers are arranged.

The main copper bar 31 constituting the charging part of the distribution board connected the thin copper bar 31a and the thick copper bar 31b in parallel. If the upper copper bar and the lower copper bar are each bent, the adhesion between the copper bars is lowered, and the quality may be lowered. Therefore, a lug terminal is provided at the lowermost part of the main copper bar 31. Could not be established.

  The lug terminal could not be provided on the distribution board, the electric wire could not be connected to the main copper bar, and the configuration content of the distribution board was limited.

  SUMMARY OF THE INVENTION Accordingly, the present invention has an object to provide a charging part of a distribution board that has a simple structure and can expand the diversity of the distribution board using the same member, and the structure of the main copper bar is a thin copper sheet. Since the lug terminal for connecting the electric wire is provided at the end of the main copper bar of the distribution board, a thin copper bar or a thick copper bar of the main copper bar is used. One of the copper bars is extended from the other copper bar, and the lug terminal is formed by bending only the extended copper bar.

  In the distribution part of the distribution board according to the present invention, the main copper bar has a double structure of a thin copper bar and a thick copper bar, and a lug for connecting an electric wire to the lowermost part of the main copper bar of the distribution board To provide a terminal, either the thin copper bar or the thick copper bar of the main copper bar is extended from the other copper bar, and only the extended copper bar is bent to form lug terminals. Therefore, the interconnection from the lug terminal can be formed, and the distribution board configuration can be varied.

  The purpose of providing diversity in the distribution board configuration was achieved without increasing the number of parts.

  A charging part of a distribution board according to the present invention will be described with reference to the attached drawing of FIG.

  The distribution board 1 is configured by arranging electrical devices such as a breaker 2. The breakers 2 are connected by a main copper bar 3 and a branched copper bar 4. The main copper bar 3 has a double structure in which a thin copper bar 3a and a thick copper bar 3b are in close contact with each other. In FIG. 1, the lower thick copper bar 3 b of the double copper bar is extended at the bottom of the charging unit, and the tip is bent to form the lug terminal 3 c.

  The lug terminal 3c is formed by extending the thick plate copper bar 3b and bending the tip thereof, and by connecting an electric wire or the like to the lug terminal, a wide variety of distribution boards can be manufactured according to the purpose.

  FIG. 2 shows a second embodiment of the charging part of the distribution board according to the present invention.

  The distribution board 5 is configured by arranging electrical devices such as a breaker 6. The breakers 6 are connected by a main copper bar 7 and a branched copper bar 8. The main copper bar 7 has a double structure in which a thin copper bar 7a and a thick copper bar 7b are in close contact with each other. In FIG. 2, the upper thin copper bar 7 a of the double copper bars is extended at the lowermost part of the charging unit, and the tip is bent to form the lug terminal 7 c.

  The lug terminal 7c is formed by extending the thin copper bar 7a and bending the tip thereof, and connecting a wire or the like to the lug terminal 7c, thereby making it possible to produce a wide variety of distribution boards according to the purpose.

  The distribution board 9 is configured by arranging electric devices such as a breaker 10. The breakers 10 are connected by a main copper bar 11 and a branched copper bar 12. The main copper bar 11 has a double structure in which a thin copper bar 11a and a thick copper bar 11b are in close contact with each other. In FIG. 3, not only the lowermost part but also the uppermost part of the charging part, one of the double copper bars 11 is extended, and the tip thereof is bent to form the lug terminal 11c.

  The main copper bar of the charging part of the distribution board has a double structure and one of the copper bars is extended, and the tip is bent to form a lug terminal. Since it can be bent as it is and the lug terminal can be connected, the distribution panel can be made in a variety of ways and a wide variety of distribution boards can be manufactured.

It is explanatory drawing which showed the charging part of the distribution board which concerns on this invention. Example 1 It is explanatory drawing which showed the charging part of the distribution board which concerns on this invention. (Example 2) It is explanatory drawing which showed the charging part of the distribution board which concerns on this invention. (Example 3) It is explanatory drawing which showed the charging part of the conventional distribution board.
