Description

  The present invention relates to a panel structure of an electronic device, and more particularly to a structure of a cable outlet provided in a panel constituting a decorative board in an electronic device that can accommodate one or a plurality of optional units.

  As a typical medical electronic device, there is an ultrasonic diagnostic apparatus (see Patent Documents 1 and 2). A large number of electronic boards are accommodated in the main body of the ultrasonic diagnostic apparatus. They include a transmission / reception substrate, an image forming substrate, a backplane (main substrate), and the like. From the apparatus main body, a power cable, an operation panel cable, a display cable, and the like constituting the basic set are drawn out of the apparatus main body. Specifically, they are pulled out via a dedicated cable outlet provided on the panel (exterior cover or decorative panel) of the main body of the device, and the amount and number of cables do not change afterwards. Basically, there is no need to make the size and shape of the cable outlet variable. It is sufficient to design the outlet according to the cable passing through.

  On the other hand, in the apparatus main body, one or a plurality of optional units are incorporated as an electronic substrate or an electronic unit as necessary. Examples of such an optional unit include a recording device, a printing device, a communication device, a measuring device (for example, an electrocardiograph), and the like. A signal cable and a power cable are pulled out from each optional unit. That is, when the optional unit is incorporated in the apparatus main body, it is necessary to draw out one or more cables from the apparatus main body. The number and quantity vary depending on the number and configuration of installed optional units. In some cases, no optional unit is provided. Under such circumstances, it can be said that a large opening (cable passage) should be formed in advance in the panel of the main body of the device when taking out the cable, but in such a case, the number of cables to be pulled out is small or the quantity Is small, there is a large gap in the opening, which not only looks bad, but also makes it easier for foreign objects to enter the apparatus. If there is no optional cable, there will be a meaningless opening. On the other hand, according to the configuration of the optional cable, designing a cable outlet (or other type of concealment part) suitable for the configuration is complicated and causes a problem of increased manufacturing costs.

Therefore, the necessary opening amount and an appropriate concealment amount can be secured by changing the form of the cable passage after the fact.

  Further, according to the above configuration, when one segment is separated and removed by breaking the connecting strip between the segments, the staying piece as a part of the connecting strip is the bottom of the recess in the other segment, that is, both sides Since it can be prevented from touching the surface of the cable, basically the residual piece can be prevented from being damaged, and the fingertip can touch the residual piece. To prevent and increase safety. It is desirable to set the depth (height of both walls) and width (especially the opening width) of the recess so that the cable and fingers do not touch the remaining piece. In addition, although a residual piece also arises on the convex portion side, it is removed together with the segment to be separated and removed. That is, there is no problem even if there is a residual piece at the tip of the convex portion. It is desirable that the segments are configured in a shape that can be closely arranged with each other. When the separation priority is set stepwise, the shape of the uppermost segment is preferably a rectangle having four sides, but may be a circle, a semicircle, or the like.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows a perspective view of an ultrasonic diagnostic apparatus according to the present invention. An ultrasonic diagnostic apparatus is an apparatus that forms an ultrasonic image based on a received signal obtained by transmitting / receiving ultrasonic waves to / from a living body, in the medical field. The present invention mainly features a cable outlet structure described in detail below, and the electronic apparatus according to the present invention is not limited to the ultrasonic diagnostic apparatus. However, in the ultrasonic diagnostic apparatus, since various optional units are provided in the apparatus main body, the cable outlet structure according to the present invention is particularly preferably provided in the ultrasonic diagnostic apparatus.

  In FIG. 1, the ultrasonic diagnostic apparatus has a main body 10. A plurality of electronic boards are accommodated in the main body 10. These include a transmission / reception substrate, an image forming substrate, and the like. A power source and the like are also provided in the main body 10. Further, one or more optional units are incorporated in the main body 10 as necessary. Such optional units are recording units, printing units, measuring units and the like. A signal cable and a power cable are drawn from each optional unit. There may be no optional unit, or there may be a large number of optional units.

  The main body 10 has four side surfaces as shown in the figure, and a panel is provided on each side surface. In the figure, a side panel 10B and a back panel 10C are shown. A top panel 10D is also shown. The lower part of the main body 10 is a base 10A, on which four casters 12 are provided. The operation unit 16 is supported by the support column 14 so as to be movable up and down, and a display 18 is mounted on the back side of the operation unit 16 via an arm mechanism. The operation unit 16 includes a keyboard, a trackball, and the like, and the user can input and operate using the operation unit 16.

  As described above, the main body 10 has a plurality of decorative plates or panels as exteriors. In the back panel 10C, in addition to a plurality of cable connectors, in this embodiment, a cable outlet structure described in detail below. 20 is provided. Such a cable outlet structure 20 may be formed in the side panel. In FIG. 1, the cable outlet structure 20 is provided on the upper left side of the back panel 10 </ b> C, but its position can be changed as necessary.

  FIG. 2 shows the entire cable outlet structure 20. The cable outlet structure 20 is formed in the back panel 10 </ b> C, and includes an opening 24 and a blind cover 26 that closes the opening 24. The blind cover 26 is divided into an upper part 26A, an intermediate part 26B and a lower part 26C from the upper side to the lower side.

  The intermediate portion 26B is constituted by a base segment 28 as a single segment in the present embodiment. As will be described later, the base segment 28 is detachably attached to the back panel 10C. The base segment 28 is basically a segment that is not separated and removed when the aperture size is variable.

  The upper part 26A and the lower part 26C have a line-symmetric configuration. The upper part 26A is composed of a segment 30 provided at the center of the upper part and two segments 32 and 34 provided so as to surround three sides among the four sides of the segment 30. The two segments 32 and 34 are connected to the base segment 28 and are supported only by the base segment 28. The segment 30 is connected to and supported by the two segments 32 and 34. The upper side of the segment 30 is close to the edge of the opening 24, but there is no connection relationship there. The same applies to the two segments 32 and 34. That is, a hierarchical structure is constructed in terms of support, or a separation priority is set. The highest segment with the highest separation priority is segment 30, the segment with the middle separation priority is segments 32 and 34, and the segment with the lowest separation priority (or non-separation) is base segment 28. is there. In this embodiment, three levels of hierarchies are set as described above, but the number of levels can be set arbitrarily.

  In the present embodiment, the segment 30 has a substantially rectangular shape, and the three sides excluding the upper side thereof are surrounded by the two segments 32 and 34. In the case where the segment 30 has a semicircular shape, for example, the shape of the segments 32 and 34 is set according to the shape.

  As described above, the lower portion 26 </ b> C has a structure symmetrical with the upper portion 26 </ b> A, that is, the lower portion 26 </ b> C has a segment 36 and two segments 38 and 40. The hierarchical relationship described above is also established in the lower portion 26C.

  In the upper portion 26A, one or a plurality of segments are separated and removed as necessary, so that a cable insertion area is freely set. The maximum passage opening can be obtained by removing all of the three segments 30, 32, and 34 at the upper part, and if necessary, the necessary segments can be similarly removed from the lower part. In the present embodiment, a plurality of segments are two-dimensionally arranged in a plane, and are connected to each other with a hierarchical relationship as described above. In the above embodiment, for example, the segment 30 is held by the two segments 32 and 34 of the next order, but the segment 30 and the opening 24 may be connected. In any case, by adopting the configuration of this embodiment, each segment can be easily removed according to the separation priority.

  In the present embodiment, the blindfold cover 26 has a size of about 70 mm in the vertical direction and a size of about 38 mm in the horizontal direction. The blindfold cover 26 has a quadrangular shape, but of course it may be circular or polygonal.

  Next, the detailed structure of the blindfold cover will be described in detail with reference to FIGS. FIG. 3 shows an enlarged view between the middle part and the upper part shown in FIG. A fixed gap is formed between the blindfold cover 26 and the opening 24, and the size G of the gap is about 0.5 mm. Of course, you may comprise so that both may fit exactly. The base segment 28 has an upper side 28A, and four concave portions 42 are formed along the upper side 28A in the upper part of the base segment 28. The horizontal width X1 of the recess 42 is approximately 3.5 mm, and the vertical height Z1 of the recess 42 is approximately 2.8 mm.

  The segment 32 has a lower side 32A, and the segment 32 has two convex portions 44 protruding from the lower side 32A toward the base segment 28, that is, downward. The segment 34 has a lower side 34 </ b> A, and the segment 34 also has two convex portions 46. The vertical height of each of the convex portions 44 and 46, that is, the protruding amount Z2 is about 2.8 mm, and the width X2 is about 2.1 mm.

  As shown in FIG. 3, four uneven meshing structures are formed between the base segment 28 and the two segments 32, 34 in the horizontal direction, and each meshing structure receives the convex portions 44, 46 and receives them. It consists of a recess 42. When the contact strip 48 described below is excluded, the convex portions 44 and 46 and the concave portions 42 are in a non-contact relationship. The center of the tip of each convex part 44, 46 and the center of the bottom of each concave part 42 are connected by a connecting strip 48. The connecting strip 48 has a width and thickness that can be easily cut. However, it has sufficient rigidity to support each segment. By bending one or both of the segments 32 and 34 by the user's artificial force, the stressed connecting strip 48 is broken. As a result, burrs are generated as residual pieces. However, the burr exists on the bottom side of the concave portion on the remaining segment side as will be described in detail later, and there is basically no cable surface or finger surface reaching there. That is, the depth and width of the recess 42 are set from the viewpoint of cable protection and biosafety, and the length of the connecting strip 48 is set.

  In addition, as shown in FIG. 2, a number of concave and convex meshing structures are formed between the segments constituting the blindfold lid 26, and each meshing structure has the same form as each other, but they are different from each other. It is also possible.

  In FIG. 4, the upper part of the blindfold cover is shown as an enlarged view. A segment 30 is provided at the upper center of the opening. Two segments 32 and 34 are provided so as to surround the three sides excluding the upper side, that is, the left side 30A, the lower side 30C, and the right side 30B, or close the area other than the segment 30 at the upper part. The segment 32 has a right side 32B and a step side 32C in contact with the segment 30 side. Similarly, the segment 34 has a left side 34B and a step side 34C that are in contact with the segment 30 side. The left side 30A of the segment 30 and the right side 32B of the segment 32 are close to each other, and the right side 30B of the segment 30 and the left side 34B of the segment 34 are close to each other. Furthermore, the lower side 30C of the segment 30 and the step sides 32C and 34C of the segments 32 and 34 are close to each other.

  A convex portion 58 is formed as protruding from the left side 30 </ b> A of the segment 30 in the left direction, and a convex portion 62 is formed as protruding from the right side 30 </ b> B of the segment 30. Further, two convex portions 60 and 64 are formed so as to protrude downward from the lower side of the segment 30. On the other hand, in the segment 32, a recess 50 is formed as a form retracted from the left side 32B to the back side, and a recess 52 is formed with a form retracted from the step side 32C to the back side. Similarly, in the segment 34, the recessed part 54 is formed with the form retracted from the left side 34B to the back side, and the recessed part 56 is formed with the form retracted from the step side 34C to the back side. The convex portion 58 and the concave portion 50 constitute an uneven mesh structure, and similarly, the convex portion 60 and the concave portion 52, the convex portion 64 and the concave portion 56, and the convex portion 62 and the concave portion 54 constitute an uneven mesh structure. In each structure, the convex part and the concave part are connected by a connecting strip 48. It is a plate-like part having a certain width and thickness. In the present embodiment, as shown in the drawing, two middle segments 32 and 34 are supported by the base segment 28, and the upper segment 30 is supported by them.

  Whether or not to separate or remove segments according to the presence / absence or number of optional units installed in the main unit at the time of shipment of the device or after shipment, specifically the number or quantity of optional cables The number of separations is appropriately set, so that a necessary amount of cable passage opening can be secured. This will be exemplified below with reference to FIGS.

  In FIG. 5, only the uppermost segment 30 has been removed, thereby forming a passage 66 in the center of the upper portion of the opening 24. The size of the passage 66 is small. As shown, two cables 68 and 70 are inserted there. The two cables are accommodated in a rectangular space surrounded by the sides 32B, 32C, 34C, 34B and the upper side of the opening 24. In that case, a residual piece 48A generated as a result of the breaking of the connecting strip is generated in each recess 50, but it is prevented from contacting the surfaces of the cables 68 and 70. That is, the width and height of the recess 50 are set under the condition that the cable surface does not come into contact with the residual piece 48A as a burr. Of course, not only the cable but also a finger or the like is prevented from coming into contact with the residual piece 48A.

  In the example shown in FIG. 6, the uppermost segment and the middle one segment are removed, thereby forming a medium level passage 72. Cables 74 to 82 are inserted there. Even in this case, even if a burr is generated in the remaining segment or the base segment 28, it does not contact the surface of the cable.

  Furthermore, in FIG. 7, all the three segments existing at the top are removed. As a result, a large passage 84 is formed. Cables 86 to 98 are inserted in the inside. As a result, even when many optional units are mounted, it is possible to ensure a sufficient opening. Further, if necessary, it is possible to secure more cable passages by expanding the opening area even under the blind cover.

  FIG. 8 shows a cross section at a position indicated by A in FIG. That is, FIG. 8 shows a cross-sectional view of the base segment mounting structure. Ribs 102 are formed on the back panel 10C. The base segment 28 has a hook 100 on the left end side thereof, which extends in the depth direction, and a claw portion 100A is provided at the tip thereof. The claw portion 100 </ b> A has a form that is hooked on the back side surface of the rib 102. On the right end side of the base segment 28, an insertion piece 104 having a stepped shape that is recessed to the back side is provided, and the insertion piece 104 is inserted into the back side of the back panel 10C. That is, the base segment 28 can be detachably attached to the back panel in such a form. Of course, the structure shown in FIG. 8 is an example, and various mounting structures can be employed. The base segment itself may have a separable structure. In this embodiment, since the blindfold cover 26 itself is detachable, after the number of cables is determined, the necessary number of segments is removed in the detached state of the blindfold cover 26, and then the lowered It is possible to perform an operation of mounting the blindfold lid 26 on the opening, and it is possible to improve the workability.

  In the present embodiment, when a cable passage is formed by removing a segment and a gap is generated between the cable and the periphery of the cable passage, rubber packing or the like may be arranged there. . In the above-described embodiment, each segment is basically composed of a vertical side and a horizontal side. However, for example, any of the segments can be configured in a hexagonal shape or a circular shape. In the embodiment shown in FIG. 2, a concentric arrangement is formed around the segment 30, that is, the cable passage can be gradually expanded outward.
