Description

The disclosure of the present specification relates to an electronic device.

For example, in an electronic device such as the printing device described in Patent Document 1 that converts an alternating current supplied from a commercial power source into a direct current and is used, the electronic device is connected to a DC (Direct Current) plug of an AC (Alternating Current) adapter. DC jack is provided. When the DC jack is provided on the surface of the housing of the electronic device, when the DC plug is connected to the DC jack, the DC plug largely protrudes from the surface of the housing. Such a configuration is not preferable not only in terms of design, but also in terms of practical use because the installation space for electronic devices is restricted.

JP, 2008-161839, A

As a method for suppressing the protruding amount of the DC plug, for example, as shown in FIG. 1, a method of forming a recess 102 in a housing 101 of an electronic device 100 and providing a DC jack 103 in the recess 102 can be considered. In this case, as shown in FIG. 2A, by configuring the DC plug 200 as a right angle connector in which the main body portion 201 and the bush portion 202 are orthogonal to each other, the protrusion amount of the DC plug 200 can be effectively suppressed. it can.

When the power cord 203 extending from the DC plug 200 is routed, the DC plug 200 may rotate with respect to the DC jack 103 with the axial direction of the center electrode as the rotation axis. When the DC plug 200 is configured as a right-angle connector, as shown in FIGS. 2A to 2D, when the DC plug 200 rotates about the axis of the center electrode as the rotation axis, the DC plug 200 is rotated. When the bush portion 202 of the device 200 runs on the surface of the housing, a force may be applied to the DC plug 200 in the axial direction of the center electrode, and the DC plug 200 may come off the DC jack 103.

In the above description, the combination of the DC plug and the DC jack has been described as an example, but the same phenomenon may occur in all connectors of electronic devices.

In view of the above circumstances, an object of one aspect of the present invention is to provide a technique for avoiding unplugging of a connector of an electronic device that the user does not intend.

An electronic device according to an aspect of the present invention includes a recess formed in a housing of the electronic device, a connector provided on a bottom surface of the recess, a main body portion, and a bush portion provided orthogonal to the main body portion. And a rotation range of the right angle connector in which the body portion is connected to the connector, and a rotation range of the right angle connector with the connection direction of the right angle connector as a rotation axis direction is regulated by abutting on the bush portion. And a restriction portion that is raised from at least one of the bottom surface and the side surface of the recess. The peripheral portion of the recess includes a region whose height with respect to the bottom surface is higher and lower than that of the bush portion in a state where the right angle connector is connected to the connector. The restricting part abuts on the bush part so that the rotation range restricted by the restricting part falls within the low region.

An electronic device according to another aspect of the present invention includes a recess formed in a casing of the electronic device, a connector provided on a bottom surface of the recess, and a rotation range of a right-angle connector connected to the connector. And a restriction portion that restricts the rotation range with the connection direction of the right angle connector as the rotation axis direction and that is protruded from at least one of the bottom surface and the side surface of the recess. The restriction portion is connected to the connector at a position where the height difference between the bottom surface and the surface of the housing is larger than the height difference between the bottom surface and the surface of the housing at the central position of the connector. The right angle connector is provided at a position where it abuts against the right angle connector when the right angle connector rotates about the rotation axis.

According to the above aspect, it is possible to prevent the connector of the electronic device that is not intended by the user from being disconnected.

Hereinafter, the electronic device 300 according to the embodiment of the present invention will be described. The electronic device 300 is, for example, a label printer, and operates with electric power supplied via an AC adapter (not shown). The electronic device 300 may include a battery, and may be used by switching between an internal power supply and an external power supply.

FIG. 3 is an example of a perspective view of the electronic device 300. FIG. 4 is an example of a side view of the electronic device 300. FIG. 5 is an example of a plan view of the electronic device 300. Hereinafter, the outer shape of the electronic device 300 will be described with reference to FIGS. 3 to 5. The XYZ Cartesian coordinate system shown in FIGS. 3 to 5 is for convenience of referring to directions. The electronic device 300 is generally installed and used such that the XY plane is horizontal.

As shown in FIGS. 3 to 5, the shape of the housing 301 of the electronic device 300 is an approximately columnar body having an oval-shaped bottom surface. As shown in FIG. 5, of the surface of the housing 301, the portion corresponding to the side surface of the column is composed of two planes parallel to the Y direction and two curved surfaces having a cross section of a substantially semicircular shape. ing. Further, recesses (recesses 302 and 310) are formed in the two curved surface portions.

As shown in FIGS. 3B, 4A, and 4B, the electronic device 300 has a recess 310 formed in the front portion of the housing 301. The recess 310 is provided with a paper discharge port 311 for discharging the printed label printed in the electronic device 300. The paper discharge port 311 is an opening parallel to the X direction.

As shown in FIGS. 3A and 4A, the electronic device 300 has a recess 302 formed in the rear portion of the housing 301. The recess 302 is formed at a position eccentric with respect to the symmetry axis AX1 of the two oval-shaped symmetry axes (AX1, AX2) shown in FIG. 5 which is parallel to the Y direction. That is, it is formed at a position decentered from the center of the housing 301 in the X direction. As a result, as shown in FIG. 4, the concave portion 302 is invisible when viewed from one side of the side surface, so that it is possible to enjoy a design advantage such as realizing a neat appearance. The recess 302 is a recess provided to prevent the DC plug 200 connected to the electronic device 300 from significantly protruding from the surface of the electronic device 300.

The DC plug 200 is a DC plug of an AC adapter. As shown in FIG. 3A, the DC plug 200 is a right angle connector and includes a main body portion 201 and a bush portion 202. The DC plug 200 and an AC adapter (not shown) are connected by a power cord 203. The main body 201 connected to the DC jack (see FIG. 6) has a columnar shape and includes a center electrode. The bush portion 202 extending from the main body portion 201 is provided orthogonal to the main body portion 201. More specifically, the bush portion 202 extends from the main body portion 201 in the direction orthogonal to the center electrode.

FIG. 6 is an enlarged view of the recess 302 of the electronic device 300. FIG. 7 is an example of a cross-sectional view taken along the line AA of the electronic device 300. FIG. 8 is a diagram showing a range in which the rotation of the DC plug 200 is restricted by the restriction unit 304. FIG. 9 is a diagram for explaining the peripheral portion 306. FIG. 10 is a diagram for explaining the height of the bush portion 202. FIG. 11 is a diagram showing how the DC plug 200 connected to the electronic device 300 rotates about the axis of the center electrode as the axis of rotation. Hereinafter, the recess 302 of the electronic device 300 will be described in more detail with reference to FIGS. 6 to 11. The XYZ orthogonal coordinate system shown in FIGS. 6 to 11 is for convenience of direction reference, and is similar to the XYZ orthogonal coordinate system shown in FIGS. 3 to 5.

As shown in FIG. 6, the recess 302 has a bottom surface 302a parallel to the XZ plane and a side surface 302b. A DC jack 303, which is a connector for connecting to the DC plug 200, is provided on the bottom surface 302a of the recess 302. As shown in FIGS. 6 and 7, the DC jack 303 has a center electrode 303a and has a symmetrical shape with respect to the center electrode 303a. The side surface 302b is a surface that connects the bottom surface 302a and the front surface 301a of the housing 301.

As shown in FIG. 6, the concave portion 302 is provided with ribs 304a and ribs 304b that are raised from the bottom surface 302a and the side surfaces 302b of the concave portion 302. The rib 304 a and the rib 304 b are a regulation unit 304 that regulates the rotation range of the DC plug 200 connected to the DC jack 303. This rotation range is a rotation range with the connecting direction of the DC plug 200 as the rotation axis direction. The connection direction of the DC plug 200 is the axial direction of the center electrode of the DC plug 200, which is the Y direction in this example.

The restriction part 304 restricts the rotation range by coming into contact with the bush part 202. As shown in FIG. 8, the rib 304a, which is the first restriction portion, has a contact surface 305a that restricts the rotation range of the DC plug 200 by contacting the bush portion 202 of the DC plug 200. Similarly, as shown in FIG. 8, the rib 304b, which is the second restriction portion, has a contact surface 305b that restricts the rotation range of the DC plug 200 by contacting the bush portion 202 of the DC plug 200. .. That is, the restricting portion 304 is located at a position where it comes into contact with the DC plug 200 when the DC plug 200 connected to the DC jack 303 rotates about the center electrode of the DC plug 200, more specifically, the bush portion 202. It is provided at the position where it abuts.

A regulation range 400 shown in FIG. 8 indicates a rotation range regulated by the regulation unit 304, that is, a range in which the DC plug 200 can rotate in the electronic device 100. Hereinafter, the regulation range 400 will be described in more detail.

The peripheral portion 306 of the recess 302 is a part of the surface 301a of the housing 301, and includes a region 306a and a region 306b as shown in FIG. The region 306a is a region whose height with respect to the bottom surface 302a is lower than that of the bush portion 202 when the DC plug 200 is connected to the DC jack 303. The region lower than the bush portion 202 is a region lower than the center height H1 of the bush portion 202 shown in FIG. Further, the area 306b is an area having a height with respect to the bottom surface 302a higher than that of the bush portion 202 when the DC plug 200 is connected to the DC jack 303.

As shown in FIG. 9, in the restricting portion 304, the bush portion 202 abuts on the restricting portion 304 (the rib 304a, the rib 304b) so that the restricting range 400 is contained in the region 306a. As a result, in the electronic device 100, the bush portion 202 of the DC plug 200 can be prevented from moving from the region 306a to the region 306b. When the bush portion 202 moves from the region 306a to the region 306b, the axial force (in this example, the positive direction in the Y direction) that causes the DC plug 200 to be pulled out is DC depending on the height of the peripheral portion 306. It joins the plug 200. By preventing this, the removal of the DC plug 200 can be avoided.

The contact surface 305 of the restricting portion 304 forms a right angle with the bottom surface 302a, as shown in FIG. The angle formed by the contact surface 305 and the bottom surface 302a is not limited to a right angle, but may be 90° or less. That is, the contact surface 305 may form a right angle or an acute angle with the bottom surface 302a.

The reason why the contact surface 305 is 90 degrees or less with respect to the bottom surface 302a is to prevent the bush portion 202 from riding on the regulation portion 304. If the bush portion 202 comes into contact with the regulation portion 304 and rides on the regulation portion 304, the bush portion 202 moves beyond the regulation range 400. By setting the contact surface 305 to be 90 degrees or less with respect to the bottom surface 302a, it is possible to avoid generation of upward force (positive direction in the Y direction) on the bush portion 202 contacting the contact surface 305. Therefore, it is possible to reduce the possibility that the bush portion 202 gets on the regulation portion 304.

The height H2 of the contact surface 305 of the restriction portion 304 is higher than the central height H1 of the bush portion 202, as shown in FIG. That is, in the electronic device 300, at least a part of the contact surface 305 is provided at a position higher than the central height H1 of the bush portion 202.

The reason why the height H2 of the contact surface 305 is made higher than the center height H1 of the bush portion 202 is to prevent the bush portion 202 from riding on the restriction portion 304. When the height H2 of the contact surface 305 is lower than the central height H1 of the bush portion 202, the central portion in the height direction of the bush portion 202 does not contact the contact surface 305 and is above the regulating portion 304. Will move up to. Therefore, as the rotation of the DC plug 200 progresses, the restriction portion 304 also digs into the lower side of the bush portion 202, and the bush portion 202 rides on the restriction portion 304. When the bush portion 202 rides on the regulation portion 304, the bush portion 202 moves beyond the regulation range 400. By making the height H2 of the contact surface 305 higher than the center height H1 of the bush portion 202, the center of the bush portion 202 moves to above the restriction portion 304 without contacting the contact surface 305. You can avoid that. For this reason, it is possible to reduce the possibility that the bush portion 202 will run over the regulation portion 304.

In the electronic device 300 configured as described above, the rotation of the DC plug 200 is appropriately restricted when the power cord 203 extending from the DC plug 200 is routed. Therefore, for example, even if the DC plug 200 rotates clockwise as shown in FIGS. 11A to 11C, it does not rotate further than the state shown in FIG. 11C. This prevents the bush portion 202 of the DC plug 200 from riding on the surface 301a of the housing 301, and as a result, the axial force of the center electrode can be prevented from being applied to the DC plug 200.

Therefore, according to the electronic device 300, even when the installation space is reduced by using the angle connector, it is possible to avoid the angle connector from being unplugged by the user.

In the above, the attention was paid to what range the regulation range 400, which is the rotation range regulated by the regulation unit 304, but the position of the regulation unit 304 itself is characterized as follows.

As shown in FIG. 8, the restriction portion 304 has a height difference between the bottom surface 302a and the front surface 301a of the housing 301 that is larger than a height difference between the bottom surface 302a and the front surface 301a at the center position of the connector (DC jack 303). It is provided. Here, the height difference between the bottom surface 302a and the front surface 301a is the height difference in the direction (Y direction) orthogonal to the bottom surface 302a, and in this example, the center height H1 shown in FIG. In the electronic device 300, the height difference between the bottom surface 302a and the front surface 301a increases in the positive direction in the X direction, and thus the restricting portion 304 is provided on the positive side in the X direction with respect to the DC jack 303. That is, the restriction portion 304 is provided at a position between the DC jack 303 and the symmetry axis AX1 parallel to the Y direction shown in FIG.

In this example, the restricting portion 304 is provided so as to come into contact with the bush portion 202 when the bush portion 202 is in a position that changes from a position smaller than the height difference at the center position of the DC jack 303 to a position larger than the height difference. ing.

The reason why the restriction portion 304 is provided at a position where the height difference between the bottom surface 302a and the front surface 301a at the center position of the DC jack 303 is larger is that the DC plug 200 (particularly, the bush portion 202) is provided at the position where the height difference is large. ) To prevent the movement. When the bush portion 202 moves to a position where the height difference between the bottom surface 302a and the surface 301a at the center position of the DC jack 303 is larger, the bush portion 202 rides on the surface 301a of the housing 301 and the DC plug 200 An axial force that causes the plug to be pulled out is applied to the DC plug 200. Since the restriction portion 304 exists at a position where the height difference between the bottom surface 302a and the front surface 301a at the center position of the DC jack 303 is larger, even if the DC plug 200 is rotated, the position where the restriction portion 304 exists is provided. The bush portion 202 cannot move. Therefore, it is possible to prevent the bush portion 202 from moving to a position where the height difference is larger than the height difference between the bottom surface 302a and the front surface 301a at the center position of the DC jack 303 where the restricting portion 304 exists.

Further, since the restricting portion 304 includes the ribs 304a and 304b, it is possible to prevent the bush portion 202 from moving to a region between the two ribs. Thereby, the movement of the bush portion 202 can be restricted over a range wider than the range spatially occupied by the restriction portion 304. In this example, as shown in FIG. 9, the central axis of the bush portion 202 can be restricted from moving beyond the restriction range 400, and the rotation range can be restricted to about 180 degrees.

The above-described embodiments are specific examples for facilitating the understanding of the invention, and the present invention is not limited to these embodiments. Various modifications and changes can be made to the electronic device without departing from the scope of the claims.

In the above-described embodiment, the example in which the electronic device 300 is the label printer has been shown, but the electronic device 300 is not limited to the label printer and may be another electronic device. Further, although an example in which the DC jack 303 and the DC plug 200 that may be pulled out due to rotation are connected has been shown, it is possible to use a connector that has an axisymmetric structure and can rotate relative to a connector of a connection partner. Other connectors may be used as long as they are available.

In the above-described embodiment, an example is shown in which the restricting portion 304 is raised from both the bottom surface 302a and the side surface 302b, but the restricting portion may be raised from at least one of the bottom surface and the side surface of the recess. As long as the structurally necessary strength can be secured, the electronic device 300 may have a restricting portion 314 protruding from only the bottom surface 302a instead of the restricting portion 304 as shown in FIG. 12, and as shown in FIG. In addition, instead of the restricting portion 304, a restricting portion 324 protruding only from the side surface 302b may be provided.

In the above-described embodiment, the example in which the restricting portion 304 is composed of two ribs (rib 304a and rib 304b) has been shown, but the restricting portion 304 may be composed of a single element. As long as sufficient space is provided in the recess 302 for inserting a finger when the DC plug 200 is inserted/removed, the electronic device 300 may include a single element instead of the restricting portion 304, as shown in FIG. The restriction unit 334 may be included.

In the above-described embodiment, the DC plug 200 and the AC adapter (not shown) have been described as devices different from the electronic device 300, but the electronic device 300 may include the DC plug 200 and the AC adapter connected to the housing 301. ..
