JPH0230198A - Lid mechanism of optional connection window - Google Patents

Abstract

PURPOSE:To eliminate a need that blades of nippers are inserted into an apparatus when a rib is cut, to make a gap between a case and a lid narrow and to prevent the inside of the apparatus from being damaged by a method wherein a plurality of ribs linking the lid filling a large part of a connection window with the case around the window are formed so as to protrude from an outer face of the lid and the like. CONSTITUTION:The following are constituted collectively: a case 2, of an electronic apparatus or the like, having a connection window 3 of an option or the like; a lid 4 which fills a large part of said window 3 and whose outer face is nearly on a face identical to an outer face of the case 2 around the window; a plurality of ribs 5 which link the lid 4 with the case 2 around it so as to protrude from the outer face of said lid 4 and the like. When the option is used, the ribs 5 are cut and the lid 4 is removed. For example, said case 2, said lid 4 and said ribs 5 are manufactured collectively by a plastic molding operation. When a person using an option cuts the ribs 5 by using nippers or the like, a part between an outer face 4a of the lid 4 and an inner face 5a of the ribs 5 is cut as a cutting face 6, the lid 4 is separated and removed; a window 3 is opened; the option can be connected.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a connection window for an option, etc. having an integrally formed lid in advance in a case of an electronic device, etc. This relates to an optional connection window cover mechanism that allows the cover to be cut out according to the requirements.

(Prior Art) Conventionally, this type of optional connection window cover mechanism has been constructed as shown in FIGS. 5 and 6.

In FIG. 5, 1 is an electronic device housing, 2 is a lower case of the electronic device, and 3 is an optional connection window with a lid formed in the lower case 2 in advance.

FIG. 6 shows the details of this optional connection window, and 11 is a lid arranged to fill most of the window 3;
Reference numeral 12 denotes a plurality of ribs that connect the lid 11 and the case 2 around the window, and the ribs 12 hold the lid 11 to the case 2. Case 2. The lid 11 and the ribs 12 are integrally manufactured, for example, by plastic molding, and their outer surfaces are flush. Therefore, the person using the option cuts the rib 12 with nippers or the like at any time, thereby removing the lid 11 and completing g3.
Options can be connected.

(Problem to be Solved by the Invention) However, in such a conventional structure, the blade of the nipper when cutting the rib 12 easily enters the gap between the case 2 and the lid 11. It was necessary to widen both sides of the rib 12 and to widen the gap width. Furthermore, in order to cut the ribs 12, the blades of the nippers must be inserted into the inside of the device, which may cause damage to the inside of the device.

The present invention solves these conventional problems,
To provide an optional connection window cover mechanism that does not require inserting nipper blades into the inside of the device when cutting ribs, can narrow the gap between the case and the lid, and does not damage the inside of the device. purpose.

(Means for solving the problem) In order to achieve the above purpose, a plurality of ribs are formed to protrude from the outer surface of the lid, etc., connecting the lid that fills most of the optional connection window and the case around the window. This is what I did.

(Function) According to this configuration, when removing the lid, the blade of the nipper is moved in a direction parallel to the outer surface of the lid, etc., and the protruding ribs are cut. There is no need to make a wide gap, and the inside of the device will not be damaged.

(Example) Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is an electronic device housing, 2 is a lower case of the electronic device, and 3 is an optional connection window with a lid pre-formed in the lower case 2. .

Figures 2 and 3 show the details of this optional connection window. 4 is a lid arranged to fill most of the window 3, and 5 is the lid 4 and the case 2 around the window. The lid 4 is held in the case 2 by a plurality of ribs 5 that connect the lid 4 to the case 2. The case 2, the lid 4, and the rib 5 are integrally manufactured, for example, by plastic molding, and the outer surfaces of the case 2 and the lid 4 are on the same plane. The feature of the present invention is that the ribs 5 are provided to protrude from the outer surface of the lid 4, etc., as shown in FIG.

Therefore, when a person using the option cuts the rib 5 with nippers or the like, he or she cuts the outer surface of the lid 4 as shown in FIG.
By cutting a cut surface 6 between the inner surface 5a of the rib 5 and the inner surface 5a of the rib 5, the lid 4 is separated and removed, the window 3 is opened, and an option can be connected.

In this embodiment configured as described above, the blades of the nippers for cutting the ribs 5 are operated only on the outside of the outer surfaces of the case 2 and the lid 4, so there is no need to insert them into the inside of the device.
Therefore, there is no need to widen the gap between the case 2 and the lid 4, and the inside of the device will not be damaged.

(Effects of the Invention) As explained above, according to the present invention, the gap between the case and the lid can be narrowed, which is preferable in terms of appearance and also prevents dust from entering. . Further, the ribs can be easily cut, and the inside of the device will not be damaged.
