Description

  The present invention relates to a housing that accommodates a circuit or the like of an electronic device, and more particularly to a housing that is provided with a blindfold so as to be cut off.

In electronic devices, etc., the electrical circuit is housed in a housing made of synthetic resin, for example, and the cable connection portion is covered with a blindfold so that it is not noticeable. A wire is connected to the connection terminal portion that is separated and exposed.
The blindfold is formed integrally with the housing at the connection portion so as to cover, for example, cable wiring openings provided at a plurality of locations on the surface of the housing containing the electronic device. It can be easily cut with a tool.

  For example, in the example shown in Patent Document 1, the blindfold plate is connected to the opening peripheral edge by a connecting part that can be easily cut, and the connecting part is cut with a cutting tool such as a nipper and removed.

FIG. 3 shows the structure for attaching the blindfold. 3A is a plan view, and FIG. 3B is a cross-sectional view in the direction of the arrow.
As shown in the figure, a plurality of blindfolding plates 110, here three connecting portions 111 are provided in the hole (opening) 109 in the cable wiring hole 109 that houses the electronic device and is provided on the surface of the casing (case) 102. Connect to the periphery. At that time, as shown in FIG. 3B, the connecting portion 111 is formed in, for example, an inverted U or V shape rising from the peripheral plane of the blindfold plate 110 and the hole 109, and the connecting portion 114 is formed with a tool such as a nipper. The blindfold plate 110 is cut off by cutting.
By configuring the connecting portion 111 in such a configuration, the uncut portion does not protrude and remain in the hole as in the case where the connecting portion 111 is disposed in the same plane as the blindfold plate 110. The covering portion of the cable inserted into 109 is prevented from being damaged or disconnected.

  Similarly, a support piece for integrally attaching the blindfold plate to the opening of the housing housing the electronic device is composed of a leg that rises from the peripheral edge of the opening and a leg that rises from the blindfold. It is configured so that the uncut portion does not protrude and remain in the hole, and one leg portion is formed to be narrower than the other width in plan view, and the portion is cut as a cut portion. The thing made easy is also known (refer patent document 2).

All of the above blindfolds are designed so that the uncut portion when cut off does not protrude into the opening (hole), so the cable cover will not be damaged or disconnected. If the part is cut carelessly, the cut blindfold may drop onto the part and then enter the inside of the housing from the gap between the part and the edge of the opening. In such a case, the blindfold plate that has fallen from a small gap must be collected, and the work is not only complicated. For example, in the case of grabbing with a tool and taking it out, the internal circuit part is inserted with a tool inserted into a narrow casing. Etc. may be damaged. To avoid this danger, you must open the front case and rear case of the closed casing and pick up the blindfold.
For this reason, the blind plate separated from the housing must be carefully separated so that it does not fall into the interior of the housing, which hinders improvement in work efficiency, particularly in field work.

Japanese Patent Laid-Open No. 11-186752 JP 2006-216592 A

  The present invention has been made in order to solve the above-mentioned problems of the conventional blindfold plate, and its purpose is to prevent the blindfold plate that has fallen on the component from entering the inside of the housing when the blindfold plate is separated. By preventing it, the cutting work can be performed quickly without considering entering the inside of the housing as in the conventional case, for example, to improve the work efficiency in the field.

According to the first aspect of the present invention, there is provided a housing including an opening formed facing a component housed therein, and an edge portion of the opening that covers the edge of the opening and is removed when the component is used. When the opening peripheral edge and the cutting member are connected to each other and have a protrusion on the upper surface thereof, the protrusion cuts the connection member and the blindfold is dropped onto the component. The blindfold functions as an intrusion prevention means for preventing the blindfold from further falling from the part in the housing.
According to a second aspect of the present invention, in the housing according to the first aspect, the protrusion is formed on an upper surface of the blindfold plate.
According to a third aspect of the present invention, in the housing according to the first or second aspect, the distance from the bottom surface of the blindfold plate to the upper end of the protrusion is smaller than the minimum distance between the inner peripheral surface of the opening of the housing and the upper surface of the component. Characterized by its long length.

(Function)
When the blindfold is cut out from the casing, the connecting portion is cut with a cutting tool such as a nipper that is held in one hand and held in the other hand. At this time, even if the blindfold plate falls from the opening onto the part, the protrusion is prevented from hitting the edge of the opening and entering the inside of the housing any more. In other words, since the blindfold plate stops in a state where it is caught on the corner of the opening on the part, it can be easily picked out or inverted and dropped outside.
Therefore, when removing the blindfold plate from the housing, the connecting portion is cut without worrying about entering the housing.

  ADVANTAGE OF THE INVENTION According to this invention, the removal operation | work of the blindfold board of the housing which accommodated components in the inside can be rapidly performed, without considering that the cut-out blindfold board penetrates into the inside of a housing. In particular, even if the blindfold is cut out by holding the casing by hand, the cutout blindfold does not enter the casing, so that the work at the site can be performed efficiently.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1A is a perspective view of a housing for electronic equipment showing one embodiment of a housing according to the present invention, and FIG. 1B is an enlarged perspective view showing a part surrounded by a circle in FIG.

  In FIG. 1, a housing 1 that stores an electronic circuit of an electronic device is composed of a front case 2 and a rear case 3 that can be divided, and is formed by combining both cases 2 and 3. A communication antenna AT connected to the housed electronic circuit is projected from the side of both cases 2 and 3 of the case 1. In the vicinity of the antenna AT, an opening 5 is provided on the rear surface side (attachment surface side) of the rear case 3, and a removable blindfold plate 6 is provided in the opening 5.

As shown in FIG. 1A and FIG. 1B, for example, an approximately rectangular cable opening 5 is provided on the bottom plate of the rear case 3 formed by molding a synthetic resin material. In the opening 5, a flat plate-like blind plate 6 is arranged with a slight gap from the inner peripheral surface, and two pieces of the blind plate 6 separated from each other by a predetermined interval on both sides thereof. It is connected with the inner periphery of the opening part 5 by the connection member 7 used as the cutting part.
2B, for example, the connecting member 7 has a substantially L-shaped cross-section and is thinner than the thickness of the blindfold plate 6, and is integrally formed on the upper surface of the blindfold plate 6 so as to extend flush with it. Therefore, it is curved at the edge of the opening 5 with a slight gap from the upper surface of the opening 5 and is integrally attached to the upper opening edge.
In addition, about a connection member, it is not limited only to the said form, For example, what was described in the said patent document 1 or 2 may be used.

Two protrusions 8 are integrally provided on the upper surface of the blindfold plate 6 in the width direction. The projection 8 cuts the connecting member 7 and falls onto a component 10 (here, a connector for wire attachment: see FIG. 2) in which the blindfold plate 6 is accommodated at the position of the opening 5 of the housing 1. Then, the blindfold plate 6 functions as an intrusion prevention means for preventing the blindfold plate 6 from entering the interior of the component 10 from the part 10.
Next, this point will be described with reference to FIG.

2 is a cross-sectional view of the housing according to the present embodiment, that is, FIG. 2A is a cross-sectional view taken along the line XX of FIG. 1A, and FIG. 2B is an enlarged view of the blindfold plate 6 of FIG. 2A. FIG.
As is apparent from FIG. 2B, there is a gap between the tip 10a of the wire attachment connector 10 which is an internal housing component of the housing and the peripheral portion 5a of the opening 5. Therefore, the connecting means 7 of the blindfold 6 When the cover is cut, the blindfold plate 6 may fall onto the connector 10 and further enter the housing 1 through the gap. As described above, when the blindfold plate 6 enters the inside of the housing 1, it is not easy to collect it.
Therefore, in the present embodiment, the protruding portion 8 is projected on the upper surface of the blindfold plate 6, and the distance (height) H of the protruding portion 8 from the lower surface of the blindfold plate 6 is the clearance, that is, the distal end portion 10 a of the connector 10. And it is comprised so that it may become longer than at least the minimum space | interval between the inner peripheral edge part 5a of the opening part 5. FIG.

  With this configuration, even when the blindfold plate 6 is separated, even if the blindfold plate 6 falls onto the connector 10 and further enters the housing 1, the protrusion 8 hits the inner peripheral edge 5a of the opening and enters there. Is blocked. That is, it is possible to prevent further intrusion of the blindfold plate 6 into the housing 1.

  When the connecting member 7 is cut and the blindfold plate 6 is removed, in this embodiment, since one end of the connecting member 7 is erected from the periphery of the opening, the root of the portion where the connecting member 7 rises from the upper edge of the opening. If the portion is cut, the uncut portion of the connecting member 7 does not remain in a state of protruding inward of the opening.

In the present embodiment, in particular, when the connecting member is cut and the operator removes the blindfold plate 6 from the housing 1 by a simple configuration in which the projection 8 is provided on the upper surface of the blindfold plate 6, the connecting member 7 is in any posture. Even if it cuts, since it does not penetrate | invade inside the housing 1, cutting work can be advanced in peace.
In particular, when the housing 1 is cut out by hand at the site, the posture of the housing 1 held in the hand is not constant, and if it is not cut carefully, a blindfold plate that does not have the protrusions 8 will drop onto the connector 10. Although it is difficult to recover by entering the inside of the container as it is, in the present embodiment, even if it falls into the housing 1, it is received on the connector 10 and never enters the inside of the housing.

  In this embodiment, two protrusions 8 are provided in parallel to the central portion of the upper surface of the blindfold plate 6, but the protrusion 8 is not limited to the central portion of the upper surface of the blindfold plate 6. Or provided on the lower surface of the blindfold plate 6 as long as a gap can be secured between the lower surface of the blindfold plate 6 and the upper end 10a of the component (connector) to be accommodated. In short, any position may be employed as long as the projection 8 does not allow the blindfold plate 6 to pass through the minimum gap between the edge of the opening and the upper end of the component (connector).

Moreover, when providing the projection part 8 in the upper surface side of the blindfold board 6, the height can be made high and it can also have a function as a knob for picking up when it falls on components.
Further, the recording protrusion 8 is not necessarily provided integrally with the blindfold plate 6, but may be formed as a separate body and then appropriately joined by a joining means such as adhesion.
