Abstract

The present disclosure relates to a distributing board having a position lock device and, more specifically, having a position lock device which can hold or release, at a specific position, an electric power device unit. The distributing board having a position lock device, according to one embodiment of the present disclosure, comprises an external case and an electric power device unit drawn into and out of the external case, and further comprises: a position setting bracket which is fixed to the external case and has convex-concave parts for setting the position of the electric power device unit; and a lock device which moves with the electric power device unit by being coupled to a portion of the electric power device unit, and which restricts or allows movement of the electric power device unit by being hooked into or released from the positions of the position setting bracket.

First claim

The invention claimed is:

1. A distributing board having a position lock device comprising:
an enclosure and an electric device unit configured to be drawn in and out of the enclosure,
a positioning bracket having;
a concave and convex part fixed to the enclosure and configured to set a position of the electric device unit, the concave and convex part includes a plurality of convex portions and concave portions formed alternately, wherein the plurality of concave portions and concave portions include a first convex portion, a first concave portion, a second convex portion, a second concave portion, a third convex portion, and a third concave portion sequentially formed from one end of the positioning bracket, and wherein the first concave portion, the second concave portion, and the third concave portion correspond to a disconnect position, a test position, and a service position of the electric device unit, respectively, and wherein adjacent ones of the convex and concave portions of the plurality of concave portions and concave portions are connected by an inclined surface, and
a test position looking groove corresponding to the test position and a service position locking groove corresponding to the service position are formed on an upper surface of the positioning bracket; and

a locking device coupled to a portion of the electric device unit to move together with the electric device unit, and configured to be locked or unlocked to or from each position of the positioning bracket so as to inhibit or allow movement of the electric device unit.

2. A distributing board having a position lock device comprising:
an enclosure and an electric device unit configured to be drawn in and out of the enclosure,
a positioning bracket having a concave and convex part fixed to the enclosure and configured to set a position of the electric device unit; and
a locking device coupled to a portion of the electric device unit to move together with the electric device unit, and configured to be locked or unlocked to or from each position of the positioning bracket so as to inhibit or allow movement of the electric device unit, wherein the locking device includes:
a case;
an upper locking member installed at the case to be movable up and down, so as to slide along an upper surface of the positioning bracket when the electric device unit is drawn in and out of the enclosure;
a lower locking member rotatably installed at the case to slide along a lower surface of the positioning bracket when the electric device unit is drawn in and out of the enclosure; and
a release plate installed on the case to move linearly in a direction orthogonal to a movement direction of the upper locking member, so as to release locking of the upper locking member,
wherein an indicator hole having an arcuate shape is formed on a side surface of the case, the indicator hole configured for viewing an indicator of the lower locking member; and

an operation member that provides a force for operating the release plate, wherein operation holes are formed on upper and lower surfaces of the case, respectively, so as to allow a portion of the upper locking member to move up and down.

3. The distributing board of claim 2 , wherein the upper locking member includes:
a body plate having a vertical portion and a horizontal portion;
a spring hole defined in the vertical portion;
a first spring installed in the spring hole;
a stopping portion protruding from a portion of the vertical portion; and
a locking protrusion fixed to a portion of the horizontal portion.

4. The distributing board of claim 3 , wherein the first spring has an upper end portion caught on an upper surface of the case to provide an elastic force for causing the upper locking member to move downward.

5. The distributing board of claim 3 , wherein a first stopping protrusion that limits movement of the lower locking member or the upper locking member is provided at one side of the vertical portion in a protruding manner.

6. The distributing board of claim 5 , wherein upper and lower grooves are respectively formed on upper and lower portions of the vertical portion adjacent to the first stopping protrusion.

7. The distributing board of claim 5 , wherein the lower locking member includes:
a stopping plate;
a rotating shaft provided at one portion of the stopping plate; and
an indicator provided at another portion of the stopping plate.

8. The distributing board of claim 7 , wherein the stopping plate is formed as a flat plate having a first corner, a second corner, and a third corner, and
wherein a second stopping protrusion that is brought into contact with or separated from the first stopping protrusion and the rotating shaft that serves as a rotation center of the lower locking member are provided at the first corner.

9. The distributing board of claim 8 , wherein a spring fixing hole in which a second spring providing an elastic force for causing the lower locking member to move upward is formed at the second corner.

10. The distributing board of claim 9 , wherein a lift prevention portion that limits upward movement of the lower locking member is formed at the third corner.

11. The distributing board of claim 9 , wherein another end of the release plate extends to define an extended portion, and a stopper that limits downward movement of the stopping plate is provided at one side of the extended portion in a protruding manner.

12. The distributing board of claim 11 , wherein a release portion formed as an inclined surface is provided on an upper surface of the release plate so that the upper locking member is moved upward when the release portion is brought into contact with the stopping portion.

13. The distributing board of claim 12 , wherein an insertion groove is formed on the upper surface of the release plate adjacent to the release portion to prevent interference of the stopping portion.

14. The distributing board of claim 2 , wherein one end portion of the release plate is bent to define a coupling portion to which the operation member is coupled.
