Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a rear window plate mounting structure for a personal computer, and more particularly to a rear window plate mounting structure that can be easily and easily detached without using screws.

[0002]

[Prior art]

 As shown in FIG. 4, the relationship between the rear plate 101 and the back window plate 2 in the conventional computer housing 1 is mainly that a window 102 is provided at a portion of the rear plate 101 facing a motherboard connection port (not shown). The back window plate 2 is attached to the window 102. The rear side plate 101 is provided with two screw holes 103 on the periphery of the window 102, and a plurality of through-holes 201 for exposing the connection ports to the outside are respectively formed in portions of the back window plate 2 corresponding to the connection ports, In addition, a through hole 202 is formed at a position corresponding to the screw hole 103, and the rear window plate 2 is fixed to the inside of the rear side plate 101 by being screwed into the screw hole 103 through the screw 203.

[0003]

[Problems to be solved by the invention]

 Although the above structure can fix the back window plate 2, there are still the following problems when actually replacing the constituent members. As computer technology advances day by day, computers are being renewed at a surprisingly high rate, and in addition to the DIY (Do it yourself) concept and the demands of personal use, computers are being rebuilt by themselves. Although the number of users who purchase and assemble is increasing, the arrangement of connection ports on the motherboard of each manufacturer is not always uniform, and the mounting position of the rear window plate 2 may need to be changed according to different connection ports. Therefore, in the method of screwing with the screw 203 as described above, every time the back window plate 2 is removed or attached, it is necessary to repeat the operation of removing and tightening the screw 203. Further, the rear window plate 2 is screwed with at least two screws 203, and loosening and tightening operations of the screws 203 are often hindered by surrounding mounting members in the housing 1, so that the operation is smooth. Inconvenience is not a problem.

[0004] In view of the problems of the above conventional example, an object of the present invention is to provide a rear window plate mounting structure that has a simple structure and allows easy mounting and dismounting of the rear window plate.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a motherboard provided in an airframe housing, a window is provided on a rear side plate of the housing at a portion facing a connection port of the motherboard, and a back window plate is attached to the window. A back window plate engaging mechanism provided with a plurality of through holes for exposing the connection port to the outside at portions corresponding to the connection port of the back window plate, wherein a plurality of holes are provided at a lower edge near a window of a rear plate of the housing. Are provided at the lower end edge side of the rear window plate at positions corresponding to the insertion holes of the housing, and are respectively fitted into the insertion holes so as to be fitted into the insertion holes, and the upper edge of the rear window plate is provided. In addition, a horizontal fixing piece that can be placed on the upper end surface of the window is formed.

A plurality of raised ears are provided on the upper end surface of the window on the rear plate of the housing, and locking holes are respectively formed in portions of the fixing piece of the back window plate corresponding to the raised ears. It is more preferable that the engaging hole engages with the engaging hole, or that the engaging projection of the back window plate has an outward bending angle.

In the present invention configured as described above, the engaging projection is inserted into the insertion hole of the rear side plate, and the engaging projection is engaged with the engaging hole. The rear window plate can be localized by frictional resistance with the insertion hole. Alternatively, if the rear window plate is pulled upward, the engaging projection and the locking hole are respectively disengaged from the insertion hole and the convex ear, and the rear window plate can be easily removed from the rear side plate.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described based on an embodiment, but the present invention is not limited to this example. As shown in FIGS. 1 and 2, a relatively preferred embodiment of the present invention is mainly provided with a window 12 on a rear plate 11 of a computer housing 10, a back window plate 20 attached to the window 12, and a back window plate. Reference numeral 20 designates a through hole 21 at a position corresponding to a connection port (not shown) of the motherboard, so that the connection port is exposed to the outside through the through hole 21.

The housing 10 is provided with three vertically oriented insertion holes 13 at the lower edge near the window 12 of the rear side plate 11, and a bi-convex ear 14 is formed at the upper end surface of the window 12 of the rear side plate 11. It has been done.

The rear window plate 20 is provided with an engagement projection 22 having an appropriate curved angle outward at a position corresponding to the insertion hole 13 of the housing 10 on the lower end edge side. A fixing piece 23 is formed on the upper end face of the fitting hole 13 so that the fixing piece 23 can be placed on the upper end face of the window 12 so that the fixing piece 23 can be placed and put out. A locking hole 231 is formed so as to be able to engage with the convex lug 14.

The above is the description of the structure, features and positioning of the preferred embodiment of the present invention, and the assembling method is as follows, as shown in FIGS. The corresponding insertion holes 13 in the side plate 11 are inserted into the corresponding insertion holes 13 to generate frictional resistance with the inner peripheral wall of the insertion holes 13 by using the bending angle of the engagement projections 22 themselves. The fixing piece 23 of 20 is pressed against the upper end face of the window 12, the fixing piece 23 is placed on the upper end face of the window 12 and placed, and the locking hole 231 and the convex lug 14 are engaged with each other. 20 is fixed to the rear side plate 1.

Conversely, when the rear window plate 20 is to be removed, the rear window plate 20 is pulled upward, and the engaging projection 22 and the locking hole 231 of the rear window plate 20 are inserted into the insertion hole of the rear side plate 11. The rear window plate 20 can be detached from the rear side plate 11 smoothly because the rear window plate 20 can be detached from the rear ear 13 and the convex ear 14.

[0013]

[Effect of the invention]

 As described above, according to the present invention, if the engagement protrusion 22 is simply inserted into the insertion hole 13 of the rear side plate 11 and the engagement hole 231 and the protrusion 14 are engaged, the engagement protrusion is formed. The rear window plate 20 can be localized by the frictional resistance between the insertion hole 22 and the insertion hole 13, and when the rear window plate 20 is pulled upward, the engagement protrusion 22 and the locking hole 231 are inserted. The back window plate 20 can be easily removed by detaching from the holes 13 and the convex ears 14, and it is convenient to replace the members.
