Description

The present disclosure relates to electronic devices.

When installing electronic equipment on a panel such as a control panel, there is a risk that the electronic equipment may fall from the panel due to the weight of the electronic equipment. Particularly in large equipment such as machine tools, the electronic equipment to be installed is relatively large, making it difficult for a single worker to install the electronic equipment while supporting the electronic equipment to prevent it from falling off the panel. In such a case, two workers are required: one to support the electronic device from outside the board and one to secure the electronic device from inside the board.

Regarding the attachment of the device to the panel, Patent Document 1 discloses a drop prevention member whose one end is housed inside the device during insertion, and whose one end protrudes outside the device and comes into contact with the back surface of the panel after insertion. A technique has been proposed that is provided on the outer periphery of the device to prevent the device from falling from the panel. In this case, the equipment can be temporarily fixed to the panel by pushing it from the outside to the inside of the panel, and the worker can go around the inside of the panel and fix the device while it is temporarily attached. The installation work can be done by one person.

However, in Patent Document 1, the operator cannot directly operate the fall prevention member from outside the board. In such a case, the device can be removed from the panel by pulling the device to release the fixation by the fall prevention member, but since a certain amount of force is required to pull the device, there is a risk that a load will be applied to the fall prevention member and it will be damaged. It is also possible to remove the fall prevention member first and then remove the equipment from the panel, but since the fall prevention member is located inside the panel, the operator must go around to the inside of the panel to remove the fall prevention member. There is.

The present disclosure has been made to solve the above problems, and aims to provide an electronic device that can be directly removed from the outside of the panel by an operator.

The electronic device according to the present disclosure includes a casing that is inserted into an opening of a board, with the surface where the entire surface is inserted as the back surface, the surface opposite to the back surface as the front surface, and the other insertion surface as the outside surface. It is provided on the outer surface as a part of the body, and the tip facing the front side is provided with a protrusion, the other end is along the outer surface, and the other end facing the back side is connected to the outer surface, All parts other than the end are separated from the outside through a hole, and when taking the case out of the opening, if you apply force to the protrusion in the direction of the inside of the case through the gap between the board and the outside, the other end will be used as a fulcrum and the inside will move. It is equipped with a movable rib that is displaced in the direction and returns to the state before the displacement when the application of force is finished.

The electronic device of the present disclosure can be directly removed from the outside of the panel by an operator.

Embodiment.
An electronic device in an embodiment will be described using FIGS. 1 to 9. Electronic devices are devices such as displays that are attached to panels such as control panels. As shown in FIG. 1, the external appearance of the electronic device 1 is composed of a housing 2 and movable ribs 3.

As shown in FIG. 2, the board 4 has an opening 4a, the left side of the board 4 is the inside of the board 4, and the right side of the board 4 is the outside of the board 4. Hereinafter, in FIGS. 4 to 9 as well, the left side of the board 4 is defined as the inside of the board 4, and the right side of the board 4 is defined as the outside of the board 4. Further, the electronic device 1 is inserted from the outside of the board 4 into the inside of the board 4 through the opening 4a. The casing 2 has a back surface 20 that is inserted into the inside of the board 4, a front surface 21 that is the opposite surface from the back 20, and an outer surface 22 that is the insertion surface of the casing 2 excluding the back 20 and front 21. . Here, the upper surface of the outer surface 22 when the casing 2 is inserted into the board 4 is the upper surface of the outer surface 22, and the lower surface is the lower surface of the outer surface 22. When inserting the electronic device 1 into the opening 4a, a portion of the outer surface 22 is inserted, but the front surface 21 is not inserted. In particular, when the electronic device 1 is a display device, the front surface 21 serves as a display surface and an operation surface of the display device.

As shown in FIGS. 1 and 2, the movable rib 3 is made of an elastic resin material and is provided on the upper part of the outer surface 22 of the housing 2 as a part of the housing 2. As shown in FIGS. As shown in FIG. 3, the movable rib 3 is provided with a locking pawl 30 as a protrusion at its tip, and the rest other than the locking pawl 30 is along the outer surface 22, and at the other end, the outer surface 22 and the movable rib 3 form a fulcrum 33. connected with. A portion of the movable rib 3 excluding the fulcrum 33 is separated from the outer surface 22 via the hole 32. This allows the movable rib 3 to move toward the inside of the housing 2 using the fulcrum 33 as a fulcrum. Further, as shown in FIG. 2, regarding the locking claw 30 and fulcrum 33 of the movable rib 3, the locking claw 30 is located on the front surface 21 side, and the fulcrum 33 is located on the back surface 20 side. Here, the locking pawl 30 has a shape that is inclined toward the back surface 20 with the front surface 21 side being the apex. By providing such an inclination, when inserting the housing 2 into the opening 4a of the panel 4, the contact between the locking pawl 30 and the panel 4 becomes smooth, and the movable rib 3 is moved toward the inside of the housing 2. Easier to displace. Further, the contact surface 31 is a recess provided in the locking claw 30. The contact surface 31 is provided to facilitate manipulation of the movable rib 3 with a jig such as a flat head screwdriver when displacing the movable rib 3 inward. Therefore, the contact surface 31 may have any shape and size as long as the movable rib 3 can be operated with a jig, and may not be provided if there is no problem with the operability of the movable rib 3.

The movable rib 3 prevents the housing 2 from falling off the board 4 by the locking claw 30. If the casing 2 is not provided with the movable rib 3, when the casing 2 is inserted into the opening 4a of the panel 4 and you release your hand, as shown in FIG. 4(a), the load on the casing 2 will be As a result, the casing 2 rotates clockwise and tilts significantly as shown in FIG. 4(b), and there is a risk that the upper part of the outer surface 22 may fall through the opening 4a and the casing 2 may fall. However, if the movable rib 3 is provided on the outer surface 22 of the housing 2 as shown in FIG. can be caught on board 4 and prevented from falling.

Next, the operation of attaching the electronic device 1 configured as described above to the panel 4 will be explained. First, as shown in FIGS. 6(a) and 7(a), the housing 2 is inserted into the opening 4a of the board 4 from the back side 20. When the housing 2 is pushed into the board 4 as it is, the locking claws 30 of the movable rib 3 come into contact with the board 4 as shown in FIGS. 6(b) and 7(b).

When the locking claw 30 of the movable rib 3 comes into contact with the board 4 and the housing 2 is further pushed into the board 4, the movable rib 3 will move as shown in FIGS. 6(c) and 7(c). When the locking pawl 30 comes into contact with the board 4, it is displaced toward the inside of the casing 2 about the fulcrum 33.

When the housing 2 is further pushed into the board 4 with the movable rib 3 displaced inward of the housing 2, the movable rib 3 becomes elastic as shown in FIGS. 6(d) and 7(d). Returns to the state before being displaced by force. If you release your hand in this state, the locking claw 30 will catch on the board 4 and the housing 2 will be temporarily fixed as shown in FIGS. 6(e) and 7(e). Even if the board 4 is pulled outward in this state, the locking pawl 30 will catch on the board 4, so the case 2 cannot be removed just by pulling the case 2 outward of the board 4.

Next, the operation of removing the electronic device 1 configured as described above from the panel 4 will be explained. First, with the housing 2 temporarily attached to the panel 4 as shown in FIG. 8(a), insert a flat head screwdriver 5 into the gap between the outer surface 22 of the housing 2 and the panel 4 as shown in FIG. 9(a). When the movable rib 3 is inserted and a force is applied inward to the housing 2 with a flat head screwdriver 5, the movable rib 3 will move around the fulcrum 33 as shown in FIGS. 8(b) and 9(b). , is displaced toward the inside of the housing 2.

When the movable rib 3 is displaced toward the inside of the casing 2, the locking claw 30 does not catch on the board 4, so when the casing 2 is pulled toward the outside of the board 4 in this state, FIGS. 8(c) and 9 As shown in (c), the housing 2 can be moved toward the outside of the board 4. Then, as shown in FIGS. 8(d) and 9(d), when the locking pawl 30 comes out to the outside of the board 4 and you stop applying force to the movable rib 3, the movable rib 3 is displaced due to the elastic force. Return to the previous state. If the housing 2 is pulled outward of the board 4 in this state, the housing 2 can be removed from the board 4 as shown in FIGS. 8(e) and 9(e). Further, as shown in FIG. 9, a taper 23 may be provided at the upper part of the outer surface 22 at a portion facing the tip of the movable rib 3 via the hole 32. By providing the taper 23, when operating the movable rib 3 with the flathead screwdriver 5, contact between the flathead screwdriver 5 and the outer surface 22 is reduced, making it easier to operate the movable rib 3.

In this way, in the electronic device 1 equipped with the movable rib 3, the housing can be opened by inserting a flathead screwdriver 5 into the gap between the outer surface 22 of the housing 2 and the panel 4 and pushing down the movable rib 3 that temporarily fixes the housing 2. The temporary fixing of the body 2 can be released. As a result, the casing 2 is pulled while being released from its temporary fixing, and the operator can directly remove the panel 4 from the outside.

In addition, in the electronic device 1 equipped with the movable rib 3, even if the movable rib 3 is displaced, when the force is removed, the elastic force returns to the state before the displacement, so the casing 2 can be simply pushed into the inside of the panel 4. Temporary fixing can be performed with the , and the temporary fixing to the board 4 can be easily done.

In addition, an example has been described in which only the movable rib 3 is provided on the upper part of the outer surface 22 of the casing 2 as a part of the casing 2. It may be provided at the bottom of 22. The shape of the immovable rib may be the same as or different from that of the movable rib 3 as long as the apex of the locking pawl is on the front surface 21 side like the apex of the locking pawl 30 of the movable rib 3. By providing the immovable ribs at the lower part of the outer surface 22 of the casing 2, the number of locking claws for fixing the casing 2 increases, so that the casing 2 can be temporarily fixed to the board 4 more reliably.

Even in the electronic device 1 configured in this way, the flow up to releasing the temporary fixing is the same as when only the movable rib 3 is provided, and the subsequent operation is to remove the casing 2 before pulling the casing 2. The only difference is that the immovable ribs are lifted so as not to come into contact with the board 4. Therefore, as in the case where only the movable ribs 3 are provided, there is an effect that the operator can directly remove the board 4 from the outside.

The present disclosure is capable of various embodiments and modifications without departing from the broad spirit and scope of the present disclosure. Further, the embodiments described above are for explaining the present disclosure, and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is indicated by the claims rather than the embodiments. Various modifications made within the scope of the claims and the meaning of the disclosure equivalent thereto are considered to be within the scope of the present disclosure.
