Description

  The present invention relates to a cover mounting structure used in an electronic device.

  Some electronic devices have a sub-cover attached to obscure the connection cable and adjustment volume.

For example, what is shown in (Patent Document 1) is a main device of a telephone device, and includes a device main body 1 and a cover 2 covering the device main body 1 as shown in FIG. The cover 2 includes a main cover 3 that covers the upper part of the front surface of the apparatus main body 1 and a sub cover (sub cover) 4 that covers the lower part. The sub cover 4 is a construction part of the apparatus main body 1. 5
Here, the construction portion 5 is a portion provided with a connection portion with a cable, such as a wiring portion of the main apparatus, and an adjustment volume.

  As shown in FIG. 9, the sub-cover 4 is provided with locking claws 6 and 7 and an engaging ring member 8 on the upper end (back side). Here, the locking claws 6, 7 are composed of a main claw 6 provided at the center of the upper end and subclaws 7 provided on the left and right of the main claw 6. Further, the ring members 8 provided on the left and right of the upper end have a shape in which a constricted insertion portion is provided in the middle.

  On the other hand, in the construction section 5 of the apparatus main body 1, the first and second insertion holes 9 and 10 for the main claw 6, the fitting opening 11 and the locking rib 12 for the sub claw 7, An operating shaft 13 for fitting the ring member 8 is provided. Here, the operation shaft 13 is composed of a pair of left and right shafts provided with a gap in the middle. By passing the constricted portion of the ring member 8 of the sub cover 4 through the gap of the operation shaft 13, the sub cover 4 can be removed.

  The sub-cover 4 attached to the operating shaft 13 by the ring member 8 is supported so as to be freely opened and closed. The sub-cover 4 thus attached has claws 6 and 7 at the upper end inserted into the insertion holes of the construction part. 9 or the fitting opening 11 allows the sub-cover to be held in an open state or maintained in a closed state.

That is, when opening the sub cover 4, as shown in FIG. 8, the top of the main claw 6 of the sub cover 4 is pushed from the surface of the main cover 3, and the back of the main claw 6 and the first insertion hole 9 (the main cover 3 Release the engagement with the rib provided on the inner side, and slide the sub cover downward. Then, the sub cover 4 is opened, and the main claw 6 is inserted into the second insertion hole 10. At the same time, the sub-claw 7 is brought into contact with the rib 12 so as to be fitted into the fitting port 11 to maintain the opened state. On the other hand, when the sub cover 4 is held in a closed state, the sub cover 4 is closed and slid upward. Then, the main claw 6 may be fitted into the first insertion hole 9 and engaged with the rib inside.
Thus, the sub-cover 4 can be kept open or closed without being screwed.

  However, in the above-described sub-cover mounting structure, since the rib, the fitting port, the operating shaft, and the like must be provided in the construction portion, the construction portion needs to be exposed from the main cover. Moreover, there is a problem that an extra sbase for providing a rib, a fitting port, an operation shaft, and the like must be secured in the construction section.

  In addition, since the operation shaft is provided in the construction section, there is a problem that when the sub cover is opened, the opened sub cover covers the construction section and it is difficult to work.

  Further, when the sub-cover is used after removing, a part of the mounting mechanism such as the rib and the operating shaft is exposed, which is unsightly, and the exposed rib and the operating shaft are sharp, which is dangerous.

  In addition, the holding of the sub cover is a method in which the main claw and the sub claw are engaged with the insertion hole and the insertion opening. For this reason, the force required for engagement is determined by the dimensions and manufacturing accuracy of the main claw, sub claw, insertion hole, and insertion opening, so adjustment is difficult, and it must be held in an open or closed state. There is a problem that fails.

  Accordingly, an object of the present invention is to allow a sub cover to be attached regardless of the presence or absence of a construction part, and in that case, to eliminate the need for extra space for attaching the sub cover to the construction part. It is to be able to be opened so that it does not get in the way, to prevent the attachment mechanism from being exposed when the sub cover is removed, and to be able to adjust the force required for opening and closing.

  In order to solve the above-described problems, the present invention comprises a main cover that covers the chassis, and a sub-cover that can be opened and closed by an arm on the open portion of the chassis excluding the cover of the main cover, A gap for inserting the arm of the sub cover is formed between the main cover and both ends of the open portion of the chassis, a screw hole is provided on the chassis side of the gap, and a through hole facing the screw hole is provided. A contact portion provided on the main cover and in contact with the arm is formed around the through hole, and a protrusion or groove extending outward from the through hole is formed in the contact portion, while the sub cover is The arm is provided at both ends, a through hole is provided at the tip of the arm, and when the arm is inserted into the gap at the tip provided with the through hole, The sliding portion is provided with a groove or a ridge extending outward from the through hole, and the sub cover arm is inserted into a gap formed at both ends of the opening portion, Match the screw holes on the chassis, the through holes in the arm, and the through holes in the main cover, insert screws through the through holes in the main cover, and fix them. A configuration is adopted in which the sub-cover is opened and closed by engaging the protrusions or grooves of the contact portion.

  By adopting such a configuration, the sub cover is attached by inserting a hook-like arm into the gap between the chassis and the main cover at both ends of the open portion. For this reason, it can be attached regardless of the presence or absence of a construction section. Further, as described above, since the sub cover is attached to the gap between the chassis and the main cover at both ends of the open part, no extra space is required for attaching the sub cover to the construction part. At this time, if the sub cover is lifted on the main cover by the arm, the sub cover can be held open so as not to interfere with the work. Moreover, since the sub cover is screwed, it can be easily removed by removing the screw. At this time, the attachment mechanism is not exposed because it is formed in the gap between the chassis and the main cover at both ends of the opening. In addition, the sub cover has a structure in which the screw hole of the chassis, the through hole of the arm, and the through hole of the main cover are aligned and screwed, so that the force required for opening and closing can be adjusted by determining the amount of engagement by tightening the screw . At this time, the arm and the main cover are locked by engaging the groove of the abutting portion and the protrusion of the sliding portion, so that the sub cover is not screwed in the opened state or the closed state. Can hold firmly. Furthermore, it can be securely fixed by tightening the screw.

  At this time, a configuration in which the sub cover is used as a protective cover for protecting the cable can be employed.

  Since the present invention is configured as described above, the attachment mechanism can be realized in a small space regardless of the presence or absence of the construction portion, and the appearance can be prevented. In addition, the force required for opening and closing can be easily adjusted and fixed in the opened and closed state.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment shown in FIG. 1, the cover mounting structure of the present application is applied to a wireless LAN access point.

  The access point has a structure in which the main cover 21 is attached to the front of the chassis 22, and an open portion (here, the side of the chassis 22) 23 excluding the covering of the main cover 21 is connected to the sub-point as shown in FIG. The cover 20 is attached.

The main cover 21 and the sub cover 20 in this form are made of resin, and the main cover 21 has a shape that covers the front surface (upper surface in the drawing) of the chassis 22 and the side surface except the opening 23 as shown in FIG. .
The open portion 23 is a portion provided with a cable terminal, a reset switch, and the like except for the covering of the main cover 21 and is a portion corresponding to a place called a construction portion in the conventional example.

As shown in FIG. 3A and FIG. 3B, gaps 24 are formed at both ends of the opening 23. The gap 24 is formed between the chassis 22 and the main cover 21, and the size of the gap 24 is set such that an arm 25 of the sub cover 20 described later can be inserted.
Further, as shown in FIG. 1, the chassis 22 is bent to form a support portion 26 on the chassis 22 side where the gap 24 is formed, and a screw hole 27 is provided in the support portion 26. On the other hand, on the main cover 21 side, a through hole 28 is provided in a portion of the support portion (on the chassis 22 side) facing the screw hole 27, and a contact portion 29 is formed around the through hole 28.
Further, the abutting portion 29 is a portion in contact with an arm 25 of the sub-cover 20 described later, and is a semi-elliptical pedestal as shown in FIG. A protrusion 30 is formed on the contact portion 29. The protrusion 30 has a rectangular parallelepiped shape formed outward from the through hole 28 (forward direction with respect to the chassis), and when attached to the chassis 22, the protrusion 30 is perpendicular to the chassis 22 as shown in FIG. 4. Become.

On the other hand, the sub-cover 20 has a configuration in which arms 25 are provided at both ends of a cover main body formed to have the same width as the opening 23. The arm 25 is provided at the upper end of the bent portion of the cover body formed in a substantially “U” shape. The arm 25 has a hook shape with a “K” shape. When the sub cover 20 is attached to the opening 23, the hook opening is located at the front of the chassis 22 as shown in FIG. 5. It is provided on the (surface) side. The arm 25 has a through hole 31 at the tip of the hook, and a sliding portion 32 around the through hole 31.
The sliding portion 32 is formed on the side of the main cover 21 that contacts the contact portion 29 as shown in FIGS. 3A and 3B when the arm 25 is inserted into the gap 24 of the opening portion 23. It is. That is, the outer side of the arm 25 is cut away as shown in FIG. 1 to reduce the thickness, and the reduced sliding portion 32 is engaged with the contact portion 29. By doing so, when the sliding portion 32 and the abutting portion 29 are engaged, the thickness is prevented from increasing and the gap 24 is prevented from becoming larger, thereby achieving a compact size.

  The sliding portion 32 is provided with two grooves 33a and 33b. The grooves 33a and 33b have a rectangular parallelepiped shape for engaging with the protrusion 30 of the contact portion 29 of the main cover 21, and the two grooves 33a and 33b are spaced from the through hole 31 by 90 °. Is provided. That is, one groove 33 a is formed to extend outward (forward) from the through hole 31 when the sub cover 20 is attached to the opening 23, and the other groove 33 b is 90 ° from the through hole 31. It is formed to extend outward (lateral direction) at intervals.

  Incidentally, the lower end of the sub-cover 20 is curved inward in order to ensure the shielding effect and prevent the end from becoming sharp. As will be described later, the size of the arm 25 is such that it is connected to the main cover 21 with the sub-cover 20 closed and positioned on the main cover 21 as shown in FIG. The size is formed and is appropriately determined according to the main cover 21. In addition, the code | symbol 35 is a hole for cable penetration, and the shielding board with a notch is attached.

  This embodiment is configured as described above, and the wireless LAN access point of this embodiment has the sub cover 20 attached to the chassis 22 with the main cover 21 attached thereto as shown in FIG.

  The sub cover 20 is attached to the open portion 23 from which the main cover 21 is removed. At this time, the sub cover 20 directs the side on which the arm 25 is provided to the opening 23, and slides the arm 25 into the gap 24 at both ends of the opening 23. Next, as shown in FIGS. 3A and 3B, the sliding portion 32 of the arm 25 that has been slid in is inserted between the support portion 26 of the chassis 22 and the abutting portion 29 of the main cover 21, The screw hole 27 of the support portion 26 of the chassis 22, the through hole 31 of the sliding portion 32 of the arm 25, and the through hole 28 of the main cover 21 are matched. Then, screws 36 are inserted into the holes 28, 29, and 31 that are made to coincide with each other and fixed with screws. At this time, the tightening amount of the screw 36 may be adjusted while moving the sub cover 20.

When the sub-cover 20 attached in this manner is in a closed state, the groove (one side) 33a of the sliding portion 32 of the arm 25 is formed on the protrusion 30 of the contact portion 29 of the main cover 21 as shown in FIG. Is temporarily fixed. Further, when opened, the other groove 33b of the sliding portion 32 is fitted into the protrusion 30 of the contact portion 29 of the main cover 21 and temporarily fixed. In this way, the grooves 33a, b of the contact portion 29 and the protrusions 30 of the sliding portion 32 are engaged and locked, so that the sub cover 20 can be opened or closed without being screwed. Can hold firmly.
At this time, when the grooves 33a and b are fitted into the protrusion 30, a click feeling and a click sound are emitted, so that the locked state can be reliably grasped.

  Further, as shown in FIG. 6, the opened sub-cover 20 can be lifted on the main cover 21 by forming the arm 25 in the shape of a “K” -shaped hook, so that it does not disturb the work. , Connecting work can be done easily. After the work, when the sub-cover 20 is closed and firmly fixed, if the screw 36 is tightened with the protrusion 30 of the sliding portion 32 fitted in the grooves 33a and 33b of the contact portion 29, the sub-cover 20 is firmly fixed. The book can be fixed.

  That is, the main cover 21 and the sub cover 20 are both made of resin. The main cover 21 is screwed to the chassis 22 with the arm 25 of the sub cover 20 interposed therebetween. At this time, since the main cover 21 and the sub cover 20 are both made of resin, the protrusions 30 of the main cover 21 are formed in the grooves 33a and 33b of the arm 25 in a temporarily fixed state where the screws 36 are loosely tightened. Even in the engaged state, the sub cover 20 can be opened and closed by bending the arm 25 inward and the main cover 21 outward. For this reason, the strength of tightening the screw 36 can adjust the final fixed state where the sub cover 20 cannot be opened and closed and the temporarily fixed state where the sub cover 20 can be opened and closed.

  At this time, the main cover 21 and the sub cover 20 are both made of resin. Even if the protrusion 30 fits in or disengages from the grooves 33a and 33b, the protrusion 30 and the grooves 33a and 33b do not wear significantly.

On the other hand, the sub-cover 20 is attached by inserting hook-like arms 25 into the gaps 24 at both ends of the opening 23. For this reason, it can be attached regardless of the presence or absence of a construction section. Therefore, an extra space for attaching the sub cover 20 to the construction part 5 is not required.
The sub cover 20 can be easily removed by removing the screw 36. At that time, the mounting structure is not exposed because it is in the gap 24 at both ends of the opening 23. The sub-cover 20 has a structure in which the screw hole 27 of the support portion 26 of the chassis 22, the through-hole 31 of the arm 25, and the through-hole 28 of the main cover 21 are aligned with each other and fixed with screws 36. Therefore, if the amount of engagement between the contact portion 29 and the sliding portion 32 is adjusted by tightening the screw 36, the force required for opening and closing can be determined. At this time, the arm 25 and the main cover 21 can be firmly held because the groove 33b of the contact portion 29 and the protrusion 30 of the sliding portion 32 are engaged and screwed together.

In this embodiment, grooves 33 a and b are formed in the sliding portion 32 of the arm 25, and the protrusions 30 are provided in the contact portion 29 of the main cover 21. However, the grooves 33 a and b are formed in the sliding portion 32 of the arm 25. Even if two ridges 30 are provided in place of b, and one groove 33a is provided in the contact portion 29 of the main cover 21 in place of the ridge 30, the same effect can be obtained.
In this embodiment, the sliding portion 32 is provided with two grooves 33a and 33b. However, the present invention is not limited to this. For example, if a groove is provided between the two grooves 33a and 33b, the sub-cover 20 can be held at a plurality of angles (multistage) between the grooves. Similarly, by providing a plurality of protrusions 30, the sub-cover 20 can be held at a plurality of angles.

  In the first embodiment, when the construction portion 5 protrudes from the main cover 20, the mounting structure of the present application is applied.

As shown in FIG. 7, the sub-cover 20 has a structure in which a hook-like arm 25 is inserted and attached between the gap 24 at both ends of the opening 23, that is, between the chassis 22 and the main cover 21. Therefore, it is attached even when the construction part 5 protrudes as shown in FIG.
Thus, regardless of the presence or absence of the construction section 5. The sub cover 20 can be attached.
