Unit case with assembly structure of mold part and straight part

The present invention relates to a unit case, and more particularly to the front frame and the rear frame by the assembly of the mold part and the linear part manufactured by the profile manufactured by die casting, the lower frame is the front frame and side frame by the sliding engagement It is configured to fasten and reduce the manufacturing cost and manufacturing time, but can more stably support the load of the components provided therein, and as each part is separated from each other, repair and inspection of the internal parts more easily It relates to a unit case having an assembly structure of the mold portion and the linear portion.

 In general, the unit case is used in the enclosure or cabinet of the electronics, or used independently.

In other words, various electronic products or printed circuit boards (PCBs) and the like are mounted inside the unit case to form a single product, which is used by mounting on a shelf or a cabinet.

As a prior art for such a unit case, registered utility model publication No. 20-0388760 is disclosed.

In the prior art, a pair of connecting rods facing each other on both sides of the left and right frames are connected to form a rectangular frame having an open opening, and the opening is coupled to a panel, and the unit case can be assembled with a cover up and down. A groove formed in the left and right frame parts to fasten the connection with the left and right frames up and down with a minimum height of the connecting rod of the connecting rod, and formed along the longitudinal direction of the pair of connecting bars so that the upper and lower covers are easily inserted. It is characterized by having a part.

That is, the prior art allows the internal parts to be repaired or inspected by removing the top cover or the front and rear panels without removing the side plate or the connecting portion of the unit case.

In this case, various parts such as a frame, a connecting table, and a handle constituting the unit case are manufactured by a profile or die casting according to a shape.

The profile is produced by processing aluminum and the like in a straight line and cutting it to a predetermined length. Die casting is a molding method using a die, and is used to mold various curved shapes that are difficult to manufacture with a profile.

In the prior art, the handle, the rear metal member, etc., because the curvature has a curved portion, it is not manufactured by the profile, it is generally manufactured by die casting, in the case of die casting, the shape of the article to be manufactured Therefore, since a mold is required, there is a limit that a lot of cost and time are required to produce a variety of specifications.

In addition, since various parts are installed inside the unit case, a considerable load is applied to the lower plate. In the prior art, the lower plate and the side plate are simply fastened by bolts, and the lower plate stably distributes the load. Failure to support it may cause problems with twisting or bending.
