Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described conventional USB hub, since the upper surface of the USB hub main body has a flat and level structure, when a user inserts and connects a connector such as a USB connector to the USB output port which is a connector port, or when disconnecting by pulling out the connector connected from the connector port, the user holds the connector with one hand and presses the upper surface of the USB hub main body housing portion with the other hand to insert or pull out the connector. However, due to the force applied from one hand, the other hand pressing the upper surface of the USB hub main body housing portion slips on the upper surface of the USB hub main body housing portion and is displaced with respect to the upper surface, resulting in a problem that it is difficult to insert or pull out the connector.

[0005] Therefore, the present invention solves the problems of the prior art as described above. That is, the object of the present invention is to provide a USB hub device that can avoid the hand pressing the upper surface of the USB hub main body housing from slipping or shifting on the upper surface of the USB hub main body housing, making it easier to insert and remove connectors.

Means for Solving the Problems

[0006] The invention according to claim 1 is a USB hub device, comprising a USB hub main body housing part and a cable with a USB connector extending from the USB hub main body housing part. The USB hub main body housing part has a plurality of connector ports on the side surface for inserting and removing connectors freely. When the installation surface is the lower surface, the upper surface on the opposite side of the lower surface has a flat portion, a concave portion recessed from the flat portion, a convex portion protruding, and at least one soft portion made of a softer material than other portions by two-color molding on the upper surface, and is integrally formed, thereby solving the above-mentioned problems.

[0007] The invention according to claim 2, in addition to the configuration of the USB hub device described in claim 1, at least one of the concave portion, convex portion, and soft portion on the upper surface of the USB hub main body housing part is provided at a position offset to the side surface side where the connector port is arranged with respect to the center on the upper surface, thereby further solving the above-mentioned problems.

[0008] The invention according to claim 3, in addition to the configuration of the USB hub device described in claim 2, at least one of the concave portion, convex portion, and soft portion on the upper surface of the USB hub main body housing part is provided in a range including at least the position corresponding to the connector port on the side surface on the upper surface, thereby further solving the above-mentioned problems.

[0009] The invention according to claim 4 further solves the above-described problems by providing at least one of the concave portion, convex portion, and soft portion on the upper surface of the USB hub main body housing portion only at a position corresponding to the connector port on the side surface on the upper surface, in addition to the configuration of the USB hub device described in claim 3.

[0010] The invention according to claim 5 further solves the above-described problems by providing, in addition to the configuration of the USB hub device described in any one of claims 1 to 4, a cable with a USB connector extending from a first side surface, which is one of the plurality of side surfaces of the USB hub main body housing portion, a connector port being disposed on a second side surface adjacent to the first side surface, a corner portion between the first side surface and the second side surface being formed in a chamfered shape, and a hole for an energization indicator lamp being provided on the chamfered surface of the corner portion.

Advantages of the Invention

[0011] The USB hub device of the present invention includes a USB hub main body housing portion and a cable with a USB connector extending from the USB hub main body housing portion, and thus can not only electrically connect to connectors of other devices such as other devices, but also exhibit the following specific effects.

[0012] According to the USB hub device of the invention according to claim 1, when a user inserts and connects a connector such as a USB connector into the connector port or pulls out the connected connector from the connector port to disconnect the connection, the user holds the connector with one hand and presses the concave portion on the upper surface of the USB hub main body housing portion, presses the vicinity of the convex portion, or presses the soft portion formed of a material such as soft rubber or silicone that fits the fingers of the hand. As a result, a grip force (frictional force) sufficient to counter the force applied from one hand is generated, avoiding the situation where the other hand pressing the upper surface of the USB hub main body housing portion slips on the upper surface of the USB hub main body housing portion or is displaced relative to the upper surface, and making it easier to insert and remove the connector. Furthermore, since at least one of a concave portion, a convex portion, and a soft portion is provided on the upper surface, a user can easily recognize the upper surface side of the USB hub main body housing even in a dark place. Also, even for a visually impaired user with poor eyesight or a blind user, since at least one of the concave portion, the convex portion, and the soft portion on the upper surface can be felt by touching it with a hand, the upper surface side of the USB hub main body housing can be easily recognized.

[0013] According to the USB hub device of the invention according to claim 2, in addition to the effects achieved by the invention according to claim 1, it becomes clear which side surface of the USB hub main body housing the connector port is provided on when viewed from the upper surface side (above). Therefore, a user can visually and easily understand the location of the connector port and insert and connect a connector to the connector port. Furthermore, even for a visually impaired user with poor eyesight or a blind user, an image of which side surface of the USB hub main body housing the connector port is provided becomes clear by the feeling of touching the upper surface with a hand without putting a finger into the connector port. Therefore, a user can sensually and easily understand the location of the connector port and insert and connect a connector to the connector port.

[0014] According to the USB hub device of the invention according to claim 3, in addition to the effects achieved by the invention according to claim 2, at least one of the concave portion, the convex portion, and the soft portion on the upper surface corresponding to (directly above) the connector port into which the connector is to be inserted is pressed, so that a gripping force (frictional force) acts linearly against the force received from the connector and a force that rotates the USB hub main body housing is not generated. Therefore, a user can insert and connect the connector straight and smoothly into the connector port. That is, when pressing a position deviated from the position on the upper surface corresponding to the connector port into which the connector is to be inserted on the side of the USB hub main body housing, a gripping force (frictional force) acts at a position deviated from the line of the vector of the force received from the connector, generating a force that rotates the USB hub main body housing, and there is a risk that the connector will be damaged without going straight into the connector port. However, since at least one of the concave portion, convex portion, and soft portion on the upper surface (directly above) corresponding to the connector port into which the connector is to be inserted is pressed, a force that rotates the USB hub main body housing is not generated, and thus the user can smoothly insert and connect the connector straight into the connector port.

[0015] According to the USB hub device of the invention according to claim 4, in addition to the effect achieved by the invention according to claim 3, since at least one of the concave portion, convex portion, and soft portion is provided at the position on the upper surface (directly above) corresponding to the connector port, the user can understand the location of the connector port by simply viewing or touching at least one of the concave portion, convex portion, and soft portion on the upper surface without directly seeing the connector port on the side.

[0016] According to the USB hub device of the invention according to claim 5, in addition to the effect achieved by the invention according to any one of claims 1 to 4, when the cable with a USB connector is inserted into the device and the USB hub device is in an energized state, the power-on indicator lamp lights up and its light is emitted to the outside through the hole for the power-on indicator lamp, and it can be visually recognized from a wide range of both the position facing the first side surface and the position facing the second side surface. Therefore, the user can easily confirm the power-on. Furthermore, when inserting the cable with a USB connector into the device, since the first side surface faces the user side, the user can confirm the power-on when inserting without changing the orientation of the USB hub device. In addition, when inserting a cable with a USB connector into a device, since the first side faces the user side and it becomes easier to check for power-on, there is no need to provide a light guide lens that protrudes from the USB hub main body housing part at the location of the power-on indicator lamp hole, so the number of components for the light guide lens can be reduced. That is, assembly can be simplified, and costs can be reduced due to the reduction in the number of components and the reduction in assembly man-hours.

Modes for Carrying Out the Invention

[0018] The USB hub device of the present invention includes a USB hub main body housing portion and a cable with a USB connector extending from the USB hub main body housing portion. The USB hub main body housing portion has a plurality of connector ports on its side surface where connectors can be inserted and removed freely. When the installation surface is the lower surface, the upper surface on the opposite side of the lower surface has a flat portion, a concave portion recessed from the flat portion, a convex portion protruding, and at least one of a soft portion made of a softer material than other portions, which is a part of the two-color molding on the upper surface, integrally formed. By this configuration, it is possible to avoid the other hand pressing the upper surface of the USB hub main body housing portion from slipping on the upper surface of the USB hub main body housing portion and shifting with respect to the upper surface, making it easier to insert and remove connectors. Even in a dark place or when the user has low vision or is blind, as long as the user can easily recognize the upper surface side of the USB hub main body housing portion, its specific implementation mode can be any.

[0019] For example, the shape of the USB hub main body housing portion in plan view can be any as long as it has connector ports on its side surface, such as circular, rectangular, triangular, quadrilateral, polygonal, etc. Also, regarding the type of the USB connector of the cable with a USB connector, it can be any USB connector such as Type A or Type C. Furthermore, the connector that can be inserted and removed freely into the connector port is not limited to a USB connector, and can be any such as a LAN connector or an HDMI connector (HDMI is a registered trademark). Also, regarding "integrally formed", it may be a configuration in which at least one of the flat portion on the upper surface of the USB hub main body housing portion and the concave portion recessed from the flat portion and the convex portion protruding is integrally formed, or a configuration in which a part of the upper surface of the USB hub main body housing portion is integrally formed by two-color molding so as to be made of a softer material than other portions. Furthermore, the "side surface" of the USB hub main body housing portion refers to the side surface with respect to the upper surface, and the "side surface" includes the front surface and the back surface.

Example

[0020] Hereinafter, the USB hub device 100 which is an embodiment of the present invention will be described with reference to FIGS. 1(A) to 6. Here, FIG. 1(A) is an upper perspective view showing the USB hub device 100 which is an embodiment of the present invention, FIG. 1(B) is a lower perspective view showing the USB hub device 100 which is an embodiment of the present invention, FIG. 2(A) is a plan view showing the USB hub device 100 which is an embodiment of the present invention as viewed from the reference numeral 2A in FIG. 1(A), FIG. 2(B) is a front view showing the USB hub device 100 which is an embodiment of the present invention as viewed from the reference numeral 2B in FIG. 1(A), FIG. 3(A) is a right side view showing the USB hub device 100 which is an embodiment of the present invention as viewed from the reference numeral 3A in FIG. 1(A), FIG. 3(B) is a bottom view showing the USB hub device 100 which is an embodiment of the present invention as viewed from the reference numeral 3B in FIG. 1(A), FIG. 4(A) is a cross-sectional view as viewed from the reference numerals 4A-4A in FIG. 2(A), FIG. 4(B) is a cross-sectional view as viewed from the reference numerals 4B-4B in FIG. 2(A), FIG. 5(A) is a plan view showing another form 1 of the USB hub device 100 which is an embodiment of the present invention, FIG. 5(B) is a plan view showing another form 2 of the USB hub device 100 which is an embodiment of the present invention, and FIG. 6 is an upper perspective view showing another form 3 of the USB hub device 100 which is an embodiment of the present invention. In addition, in FIGS. 4(A) and 4(B), in order to facilitate the understanding of the shape of the upper surface 112 of the USB hub main body housing portion 110, only the USB hub main body housing portion 110 is shown, and the illustration of the substrate and the connector port 130 inside the USB hub main body housing portion 110 is omitted.

[0021] As shown in FIGS. 1(A) to 4(B), the USB hub device 100 which is an embodiment of the present invention includes a USB hub main body housing portion 110 and a cable 120 with a USB connector extending from the USB hub main body housing portion 110. As an example, the shape of the USB hub main body housing portion 110 is a substantially rectangular shape with rounded corners in plan view. Also, as an example, the USB connector of the cable 120 with a USB connector is Type A.

[0022] Furthermore, the USB hub main body housing portion 110 has a plurality of connector ports 130 on the side surface 111 that allow connectors to be inserted and removed freely. As an example of the types of the connector ports 130, ports for USB connectors are provided at three locations on the front side surface 111 (front surface 111b) and one location on the left side surface 111c. There is at least one port for a USB connector, and the total number of the connector ports 130 may be two or more.

[0023] Also, in this embodiment, the USB hub main body housing portion 110 has a flat portion 112a on the upper surface 112 opposite to the lower surface when the installation surface is the lower surface, a concave portion 112b recessed from the flat portion 112a, a protruding convex portion, and a concave portion 112b as at least one of soft portions made of a softer material than other portions, which is a part of two-color molding on the upper surface, integrally formed. Here, the concave portion 112b is illustrated as an example, but it may be a convex portion, a soft portion made of a softer material than other portions, or a combination thereof, of course.

[0024] Thus, when the user inserts and connects a connector such as a USB connector to the connector port 130 or disconnects the connected connector from the connector port 130 by pulling it out, the user holds the connector with one hand and presses the concave portion 112b on the upper surface 112 of the USB hub main body housing portion 110, presses the vicinity of the convex portion, or presses a soft portion formed of a material such as soft rubber or silicone that fits the fingers of the hand, so that a gripping force (frictional force) sufficient to counteract the force applied from one hand is generated. As a result, it is possible to avoid the other hand pressing the upper surface 112 of the USB hub main body housing portion 110 from slipping on the upper surface 112 or shifting with respect to the upper surface 112, and to facilitate the insertion and extraction of the connector.

[0025] Furthermore, at least one of a concave portion 112b, a convex portion, and a soft portion is provided on the upper surface 112. As a result, even in a dark place, the user can easily recognize the upper surface 112 side of the USB hub main body housing portion 110. Also, even a visually impaired user with poor eyesight or a blind user can feel at least one of the concave portion 112b, the convex portion, and the soft portion on the upper surface 112 by touching it with their hand. As a result, the upper surface 112 side of the USB hub main body housing portion 110 can be easily recognized.

[0026] Furthermore, in the present embodiment, as shown in FIGS. 1(A) and 2(A), the concave portion 112b as at least one of the concave portion 112b, the convex portion, and the soft portion on the upper surface 112 of the USB hub main body housing portion 110 is provided at a position offset to the side surface 111 (front surface 111b) side on the side where the connector port 130 is arranged with respect to the center on the upper surface 112. Thereby, it becomes clear from above (from the upper surface 112 side) which side surface 111 of the USB hub main body housing portion 110 the connector port 130 is provided on. As a result, the user can visually and easily understand the location of the connector port 130 and insert and connect a connector to the connector port 130.

[0027] Furthermore, even for a visually impaired user with poor eyesight or a blind user, an image of which side surface 111 of the USB hub main body housing portion 110 the connector port 130 is provided on becomes clear from the feeling of touching the upper surface 112 with their hand without putting their finger into the connector port 130. As a result, the user can sensually and easily understand the location of the connector port 130 and insert and connect a connector to the connector port 130.

[0028] Here, the connector port 130 of the USB hub main body housing portion 110 is provided at three locations on the front side surface 111 (front surface 111b) and one location on the left side surface 111c. Therefore, as shown in FIG. 5(A), on the upper surface 112 of the USB hub main body housing portion 110, an "L"-shaped concave portion 112b that is displaced toward the left side surface 111c side and the front side surface 111b side with respect to the center may be formed.

[0029] As a result, it becomes immediately apparent from the upper surface 112 side (above) which side surface 111 of the USB hub main body housing portion 110 the connector port 130 is provided on. Furthermore, even for visually impaired users with poor eyesight or blind users, the image of which side surface 111 of the USB hub main body housing portion 110 the connector port 130 is provided on becomes even clearer by the feeling of touching the upper surface 112 with the hand without putting a finger into the connector port 130.

[0030] Also, in this embodiment, as shown in FIG. 5(A), the concave portion 112b, as at least one of the concave portion 112b, convex portion, and soft portion on the upper surface 112 of the USB hub main body housing portion 110, is provided in a range that at least includes a position corresponding to the connector port 130 on the side surface 111 on the upper surface 112. As a result, at least one of the concave portion 112b, convex portion, and soft portion on the upper surface 112 corresponding to (directly above) the connector port 130 into which the connector is to be inserted is pressed, so that a gripping force (frictional force) acts linearly against the force received from the connector, and a force that rotates the USB hub main body housing portion 110 is not generated. As a result, the user can insert and connect the connector straight and smoothly into the connector port 130.

[0031] That is, when pressing a position displaced from the position of the upper surface 112 corresponding to the connector port 130 where the connector is to be inserted on the side of the USB hub main body housing portion 110, a gripping force (frictional force) acts at a position displaced from the line of the vector of the force received from the connector, generating a force that rotates the USB hub main body housing portion 110, and there is a risk that the connector will not be inserted straight into the connector port 130 and will be damaged. However, when at least one of the concave portion 112b, convex portion, and soft portion of the upper surface 112 corresponding to the connector port 130 where the connector is to be inserted (the directly above position) is pressed, a force that rotates the USB hub main body housing portion 110 is not generated. As a result, the user can insert and connect the connector straight and smoothly into the connector port 130.

[0032] Furthermore, in this embodiment, as shown in FIG. 5(B), the concave portion 112b, which is at least one of the concave portion 112b, convex portion, and soft portion of the upper surface 112 of the USB hub main body housing portion 110, may be configured to be provided only at a position corresponding to the connector port 130 on the side surface 111 on the upper surface 112. That is, the position of the concave portion 112b corresponds to the position of the connector port 130 on the side surface 111, and the number of the concave portions 112b corresponds to the number of the connector ports 130 on the side surface 111. Thereby, at least one of the concave portion 112b, convex portion, and soft portion is provided at a position of the upper surface 112 corresponding to (the directly above position of) the connector port 130. As a result, the user can understand the location of the connector port 130 just by visually observing or touching at least one of the concave portion 112b, convex portion, and soft portion of the upper surface 112 without directly seeing the connector port 130 on the side surface 111.

[0033] Note that, as described above, the USB hub main body housing portion 110 may be integrally formed by two-color molding. In this case, among the USB hub main body housing portion 110, the soft portion, which is a part of the upper surface 112, is configured to be molded from a softer material than the other parts. For example, the USB hub main body housing portion 110 may be integrally formed by two-color molding such that a soft portion is located in the concave portion 112b. As a result, the soft portion is softer than other portions and is formed of a material such as rubber or silicone. When a user presses it with a hand, the fingers of the hand fit into the soft portion, making it difficult to slip. As a result, similar to the configuration having the concave portion 112b or the convex portion, it is possible to facilitate the insertion and extraction of the connector.

[0034] Also, in the present embodiment, as shown in FIGS. 1(A), 2(B), and 3(A), a cable 120 with a USB connector extends from the right side surface 111a, which is one of the plurality of side surfaces 111 of the USB hub main body housing portion 110. A connector port 130 is provided on the front surface 111b, which is the second side surface adjacent to the right side surface 111a, which is the first side surface. Furthermore, the corner portion between the right side surface 111a, which is the first side surface, and the front surface 111b, which is the second side surface, is formed in a chamfered shape. At the same time, an energization indicator lamp hole 113a is provided in the chamfered surface 113 of the corner portion.

[0035] As a result, when the cable 120 with a USB connector is inserted into the device and the USB hub device 100 is energized, the energization indicator lamp lights up, and the light is emitted to the outside from the energization indicator lamp hole 113a, making it visible from a wide range of positions on both the side facing the right side surface 111a, which is the first side surface, and the side facing the front surface 111b, which is the second side surface. As a result, it is possible for the user to easily confirm the energization. Furthermore, when inserting the cable 120 with a USB connector into the device, the right side surface 111a, which is the first side surface, faces the user side. As a result, the user can confirm the energization at the time of insertion without changing the orientation of the USB hub device 100.

[0036] Also, when inserting the cable 120 with a USB connector into the device, since the right side surface 111a, which is the first side surface, faces the user side and it becomes easier to check for power-on, there is no need to provide a light guide lens protruding from the USB hub main body housing portion 110 at the location of the power-on indicator lamp hole 113a. As a result, the number of components for the light guide lens can be reduced. That is, the assembly can be simplified, and the cost can be reduced due to the reduction in the number of components and the reduction in the assembly man-hours.

[0037] Regarding the chamfered surface 113 at the corner where the power-on indicator lamp hole 113a is provided, it is the chamfered surface 113 at the corner between the right side surface 111a, which is the first side surface, and the front surface 111b, which is the second side surface. However, it may also be the corner between the right side surface 111a, which is the first side surface, the front surface 111b, which is the second side surface, and the upper surface 112. As a result, it can be visually recognized from a wide range of three positions, namely, the position facing the right side surface 111a, which is the first side surface, the position facing the front surface 111b, which is the second side surface, and the position facing the upper surface 112. As a result, it becomes even easier for the user to check for power-on.

[0038] Also, in the above-described embodiment, the USB connector of the cable 120 with a USB connector has been described as being of type A as an example, but it is not limited to type A. For example, as shown in FIG. 6, the USB connector of the cable 120 with a USB connector may be of type C as an example.

[0039] The USB hub device 100, which is an embodiment of the present invention obtained in this way, includes a USB hub main body housing part 110 and a cable 120 with a USB connector extending from the USB hub main body housing part 110. The USB hub main body housing part 110 has a plurality of connector ports 130 on the side surface 111 where connectors can be inserted and removed freely. On the upper surface 112 opposite to the lower surface when the installation surface is the lower surface, there is a flat portion 112a, a concave portion 112b recessed with respect to the flat portion 112a, a protruding convex portion, and at least one soft portion made of a softer material than other portions, which is a part of two-color molding on the upper surface 112. By having such a configuration integrally molded, it is possible to avoid the other hand pressing the upper surface 112 of the USB hub main body housing part 110 from slipping on the upper surface 112 and shifting with respect to the upper surface 112, making it easier to insert and remove the connector. Even in a dark place or when the user has low vision or is blind, the user can easily recognize the upper surface 112 side of the USB hub main body housing part 110.

[0040] Furthermore, at least one of the concave portion 112b, the convex portion, and the soft portion on the upper surface 112 of the USB hub main body housing part 110 is provided at a position offset to the front side surface 111 (front surface 111b) side, which is the side where the connector port 130 is arranged with respect to the center on the upper surface 112. Thus, the user can visually and easily understand the location of the connector port 130 and insert and connect the connector to the connector port 130. Even for a user with low vision or a blind user, the user can sensually and easily understand the location of the connector port 130 and insert and connect the connector to the connector port 130.

[0041] Also, at least one of the concave portion 112b, the convex portion, and the soft portion on the upper surface 112 of the USB hub main body housing part 110 is provided in a range including at least the position corresponding to the connector port 130 on the side surface 111 on the upper surface 112. Thus, the user can insert and connect the connector straight and smoothly to the connector port 130.

[0042] Furthermore, at least one of the concave portion 112b, convex portion, and soft portion on the upper surface 112 of the USB hub main body housing portion 110 is provided only at a position corresponding to the connector port 130 on the side surface 111 on the upper surface 112. Thus, even without directly viewing the connector port 130 on the side surface 111, the user can understand the location of the connector port 130 just by viewing or touching at least one of the concave portion 112b, convex portion, and soft portion on the upper surface 112.

[0043] Also, among the plurality of side surfaces 111 of the USB hub main body housing portion 110, a cable 120 with a USB connector extends from a first side surface 111a which is one of the side surfaces 111, a connector port 130 is disposed on a second side surface 111b adjacent to the first side surface, a corner portion between the first side surface and the second side surface is formed in a chamfered shape, and an energization indicator lamp hole 113a is provided in a chamfered surface 113 of the corner portion. As a result, the user can easily confirm energization. When inserting, the user can confirm the energization without changing the orientation of the USB hub device 100. The number of components for the light guide lens can be reduced, assembly can be simplified, and the cost can be reduced due to the reduction in the number of components and the reduction in assembly man-hours. The effect is significant.
