Description

  The present invention relates to a cabinet structure of an electronic device including a lower case and an upper case.

  There are various types of electronic devices, and there are various designs. The cabinet is generally molded of plastic and contains a chassis configured with various electronic components attached. Although it is good if the cabinet is integrated, a gap may be generated between the upper and lower cases when the lower case and the upper case are combined. Each part of the cabinet, which has been thinned to save material, is easily deformed, which creates gaps in the joint surface. The gap can be seen from the outside and the appearance of the electronic device is impaired.

  As a conventional technique for preventing backlash between the lower case and the upper case in the cabinet constituted by the upper and lower cases as described above, a “plastic casing” according to Japanese Utility Model Laid-Open No. 3-25283 is known. That is, the first housing having an opening and a second housing having an opening into which a peripheral edge of the first housing on the opening side is fitted, the first housing A recess is formed in one of the first and second housing parts, and the first housing part engaged with the recess and fitted in the second housing part is formed on the other of the second housing part and the second housing part. In the plastic housing provided with a claw portion for preventing movement in the direction opposite to the insertion direction of the second housing portion, the second housing portion is provided in the vicinity of each of the opposing inner wall surfaces of the second housing portion. A guide portion that contacts the end surface of the peripheral edge portion that is fitted into the opening of the housing portion is provided, and the surface that contacts the end surface of the guide portion is the inner wall surface as the end surface moves in the insertion direction along the surface. Inclined to approach.

  Therefore, if the first casing portion is combined with the second casing portion, the peripheral portions provided in the first casing portion and the second casing portion are in close contact with each other, and no gap is generated between them. There is no rattling. However, this plastic housing has a structure in which the outer surface and the inner surface of the peripheral portion formed in the first housing portion and the second housing portion are in contact with each other without any gap. A gap is left between the side plates of the two housing parts.

A guide portion is provided to bring the peripheral portions of the first and second housing portions into contact with each other. If there is an error in the dimension of the inclined surface at the upper end of the guide portion, a gap is generated. The chassis will be loose. On the other hand, since the plastic housing has a connecting structure in which a concave portion and a claw portion are engaged with the concave portion, it is difficult to remove the first housing portion, which is troublesome during repair and maintenance.
“Plastic housing” according to 3-25283

That is, the height of the side plate is different depending on the position, and is a joining surface inclined in the front-rear direction. However, since the sum of the height dimensions of the lower case side plate and the upper case side plate at all positions is equal, the upper surface of the upper case is horizontal.

  A hook is provided on the inner side in the vicinity of the upper edge and the inner side in the vicinity of the lower edge of the side plates of the lower case and the upper case. The hooks engage with each other to form a joint surface that allows the upper and lower edges of both side plates to contact each other without a gap. Here, by placing the upper case on the lower case and sliding along the upper edge of the side plate, the hook on the upper case side plate can be engaged with the hook on the lower case side plate. On the hook, the upper and lower edges of the both side plates are in contact with each other without a gap, and a fitting portion is formed to prevent displacement to the inside and outside.

  At least two hooks are provided on one side plate of the upper and lower cases, but a guide is provided in order to prevent displacement between the hooks and other side plate portions. When a guide groove is formed inside one of the side plates and a guide piece is provided inside the other side plate, when the upper case is covered with the lower case, the guide piece fits into the guide groove so that the upper and lower edges of the side plate Misalignment is prevented.

  The cabinet according to the present invention is configured by a combination of the lower case and the upper case as described above, but the front panel may be configured as a separate member in addition to the lower case and the upper case. In the case of the two-piece structure of the upper and lower cases, the front panel is integrally formed with part of the lower case and the upper case.

  The cabinet of the electronic device of the present invention is configured by combining a lower case and an upper case, and the lower case side plate and the upper case side plate are curved as necessary to project outward, and the joint surface is inclined. . However, the lower plate and the upper plate are provided with hooks. By sliding the upper case along the upper edge of the lower plate of the lower case, the upper and lower hooks are engaged with each other and firmly combined, and the joint surface is misaligned. Without joining and without generating a gap.

  In addition to the hooks, guide portions and guide pieces that fit into guide grooves formed in the guide portions are provided on the upper and lower side plates. Therefore, displacement of the joining surfaces of the upper and lower plates is prevented, and the edges of the upper and lower plates are correctly joined without causing a step even at locations other than the hooks. Therefore, there is no backlash between the combined upper and lower cases.

  When removing the upper case, it can be easily separated by sliding it in the opposite direction, which is convenient for repair and maintenance. In this way, by providing hooks and guide portions and guide pieces on the upper and lower side plates, the strength and rigidity of the side plates are increased, and even if the upper and lower side plates protrude outward, especially in the cabinet shape of the present invention, the strength is increased. There is no problem. That is, the hook, the guide portion, and the guide piece can exhibit a function as reinforcement.

  On the other hand, in the case of a three-piece structure in which the front panel is configured as an independent member, since the front panel is provided with a locking claw, it can be easily attached to the front portion of the shield case.
