Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cover panel connecting structure and a case manufactured by using the cover panel, and more particularly, to a cover panel connecting structure and a cover panel connecting structure capable of completely connecting cover panels to each other with a small number of tightening points. Regarding cases manufactured by utilizing.

[0002]

[Prior art]

 Electrical and electronic devices such as computer-related devices are generally used with a cover panel to protect their main devices and elements from physical shock, water droplets, dust, dirt, etc. is there. This cover panel is usually made of metal plate fixed with screws, but many screws are required, and there were problems that the water resistance and water drop resistance of the screwed parts were not very good. . In addition, since many screws are used, workability is poor, and at the same time, aesthetics are impaired.

[0003]

[Problems to be solved by the device]

 Therefore, there has been a demand for providing a cover panel connecting structure that can reliably connect the cover panels without using many screws, has excellent water drop resistance, and has an excellent design. .

[0004]

[Means for Solving the Problems]

 As a result of research on the method of joining the cover panel, the present inventor has found that the above problems can be solved by using a joining piece and a joining groove and performing the joining by using pressure welding with a tapered screw. completed.

That is, the present invention comprises a panel having a coupling groove at the tip and a coupled panel having a coupling piece at the tip, the coupling groove having an engaging concave surface for engaging one end of the coupling piece and a screw receiving plate. And a screw receiving surface of the coupling groove and a screw receiving surface of the coupling piece. It provides a cover panel connection structure that forms a screw hole.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment of the present invention. FIG. 1 is a view showing a state in which a front panel (not shown) of a case assembled by using a cover panel connecting structure of the present invention is removed, and FIG. 2 is an enlarged sectional view showing only a cover panel connecting structure. Is.

In the drawings, A is a panel, B is a panel to be joined, a is a joining groove, b is a joining piece, c is an engaging concave surface, d is a screw receiving surface, e is an engaging convex surface, and f is a screw receiving surface. Surfaces and g indicate screw holes (voids), respectively.

In FIG. 1, a panel A is a side cover panel having coupling grooves a opened at the upper and lower ends in the depth direction. On the other hand, the to-be-joined panel B is a nadir cover panel in which the joining pieces b which can be inserted into a of A are formed at both ends thereof. As shown in FIG. 2, an engaging concave surface c is formed on the left inner side surface of a, and a screw receiving surface d is formed on the right inner side surface. On the other hand, an engaging convex surface e is provided on the left side of b, and a screw receiving surface f is provided on the right side of b.

When these A and B are combined, a screw hole (gap) g formed by f and d is generated. This gap of g is a gap at which the opposing c and e can be pressure-welded with a necessary and sufficient force by inserting a screw while keeping a slight gap. Then, when a taper tapping screw having a sufficient diameter and length is screwed into g, b of FIG. 2 is pressed to the left as the screw enters, and part or all of c and e are strongly pressed, As a result, the side cover panel A and the nadir cover panel B are connected and fixed. That is, in the cover panel coupling structure shown in FIG. 2, A and B are sufficiently connected and fixed by the combination of the concave arc surface of c and the convex arc surface of e.

Since A and B are coupled by such a mechanism, a of A is sufficiently long with respect to the length of the screw to be screwed into the front surface portion and the rear surface portion of the case. It is also required that the length of b of B be a sufficient length in the depth direction of the case relative to the length of the screw to be screwed.

When the above-mentioned connecting and fixing operation is carried out at four positions on the front surface and four positions on the rear surface of the case of FIG. 1, the nadir and both side cover panels are completely connected to each other to assemble a case of which front and rear surfaces are open. In addition, if the screw-threaded portion on the cover panel side is a countersink hole, a countersunk screw can be used as a screw used for connecting and assembling. To attach the front and rear panels, position the stop holes of the front and rear panels at the same position as g of the case shown in Fig. 1 so that the screws for connecting and assembling the nadir cover panel and both side cover panels are attached to the front 4 You can fasten both the book and the 4 rear panels in common.

FIG. 3 is a view showing a combined structure of cover panels in which a and b are turned upside down with respect to FIG. Thus, even if the positions of a and b are interchanged, the two panels A and B can be connected and fixed by the same principle as described above.

FIG. 4 shows another embodiment of the present invention, in which both side cover panels and bottom cover panel of the case are integrally formed, and the connecting and fixing method according to the present invention is provided only at two upper and right sides. It is sectional drawing of the case to which is applied. In the case of this embodiment, it is sufficient to screw in the screws for connecting the panels to each of the two front and rear surfaces.

5 and 6 are views showing an engagement concave surface c and an engagement convex surface e which are different from those shown in FIG. In FIG. 2, c and e are a combination of a concave arc surface and a convex arc surface, but the invention is not limited to this, and a screw is screwed into the screw hole g formed by the screw receiving surfaces d and f. , C and e may be engaged with each other. For example, as shown in FIG. 5, a part or all of them have a fitting relationship at the time of pressure contact, or as shown in FIG. It may have a shape.

[Effect of the invention]

 INDUSTRIAL APPLICABILITY The cover panel connection structure of the present invention can be advantageously used for assembling a case formed of a material having elasticity and strength to some extent, such as metal, plastic, and wood. Since the number of surfaces requiring screws is limited to two, it is possible to provide a case with an elegant design in which the screws are not exposed on the nadir or both side surfaces, for example.

Further, since the joint structure of the present invention is joined by pressure contact, it is difficult for water and the like to enter from this joint portion, and by considering the direction of use, it is possible to provide a case that is drip-proof and waterproof. Furthermore, if extruded molds are used for the members, it is possible to save labor in the work, only screws for two faces are required, and screws for mounting front and rear panels are not required separately. There is also a great effect in the work process.
