Description

  The present invention relates to a modular jack cover for preventing unauthorized use of a modular jack formed on an electronic device such as a hub.

  Some electronic devices include a plurality of modular jacks such as a hub. A modular plug can be attached to each of these modular jacks. However, in such an electronic device including a plurality of modular jacks, a modular jack that is not used may be generated, and the modular jack is likely to be used, and the security of the electronic device is low.

  Therefore, as in Patent Document 1 below, a connection protection cap that guards against unauthorized use of a modular jack that has not been used in an electronic device including a plurality of modular jacks has been proposed.

JP 2010-182689 A

  However, the conventional connection protection cap is formed in a band shape and is disposed on the front side of the modular jack via a gap. Since the band-shaped connection protection cap is arranged on the front side of the modular jack through a gap in this way, it is easy to make fingers contact with the modular jack, and the connection protection cap is easily deformed or damaged due to mischief, etc. In that case, the unused modular jack is easily used illegally, and the security of the electronic device cannot be improved.

  Therefore, an object of the present invention is to provide a cover for a modular jack that can improve the security of an electronic device equipped with the modular jack.

The present invention is a cover for a modular jack that is attached to an electronic device having a side-by-side surface in which a plurality of modular jacks are arranged side by side through a mounting structure, and is formed in an inner space and protrudes from the side-by-side surface. A box-shaped main body with a narrow opening formed in the main body. The narrow opening allows the cord connected to each modular plug attached to the modular jack to be inserted and prevents the modular plug from being inserted. The main body is configured by a combination of a plurality of divided members that divide the narrow mouth portion, and is attached to an electronic device so as to cover at least one of the plurality of modular jacks. . In addition, the modular jack cover of the present invention can be configured such that the divided members are assembled by being attached to the electronic device in a state where the divided members are combined.

  The cover for the modular jack configured as described above is such that the box-shaped main body is put on the modular jack, and the narrow opening is sized so that the cord connected to the modular plug can be inserted and the modular plug cannot be inserted. Since it is set, it is impossible to access a modular jack that is not in use, and it is not possible to insert a modular plug into a modular jack that is not in use.

  The modular jack cover having the above-described configuration is attached to the electronic device so as to cover the modular jack with the modular plug inserted into the modular jack of the electronic device. That is, in a state where the divided members are not combined, the cord connected to the modular plug inserted into the modular jack is aligned with a corresponding portion of the narrowed portion of the divided member, and then the narrowed portion is formed. The divided members are combined to form a main body, which is attached to an electronic device.

  In the modular jack cover of the present invention, the main body can be configured to cover all of the plurality of modular jacks provided in the electronic device. According to this configuration, the modular plug cannot be removed from the modular jack in which the modular plug is inserted and used, and the modular plug cannot be inserted into the unused modular jack.

  In the cover for modular jacks of the present invention, it is possible to adopt a configuration in which the main body projects forward from the parallel surface in a state of being covered with the modular jack, and the narrow opening portion is disposed at the front portion of the main body. According to this configuration, since the distance from the narrow opening portion to the modular jack is increased by the amount that the main body projects forward from the side-by-side surface, it is difficult to access the unused modular jack.

  In the modular jack cover of the present invention, it is possible to adopt a configuration in which the main body is narrowed toward the narrow opening. According to this configuration, it is possible to suppress an increase in the size of the entire modular jack cover, and it is possible to suppress an increase in manufacturing cost by suppressing the amount of material used for manufacturing.

  According to the cover for a modular jack of the present invention, the thing covered on the modular jack is a box-shaped main body, and the narrow opening portion allows the cord connected to the modular plug to be inserted, and prevents the modular plug from being inserted. Since it is set to a size, it is impossible to access a modular jack that is not used, and it is impossible to insert a modular plug and use it, so that the security of the electronic device can be improved.

  Hereinafter, the cover for modular jacks of the present invention will be described with reference to the drawings. First, a modular jack cover (hereinafter simply referred to as “cover”) 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7. As shown in FIG. 1, the cover 1 is an electronic device (in this case, a “hub”) 3 including a plurality of modular jacks 2A, 2B, 2C, 2D, 2E, 2F, 2G, and 2H arranged in parallel. Are attached (fixed) to the electronic device 3 so as to cover the modular jacks 2A to 2H (modular jack portions). The cover 1 covers the modular jacks 2A to 2H so that the modular jacks 2A to 2H that are not used in the electronic device 3 cannot be used illegally.

  In the present embodiment, the electronic device 3 is formed in a rectangular parallelepiped shape. The electronic device 3 includes a parallel surface 3A in which modular jacks 2A to 2H are provided in parallel. Since the juxtaposed surface 3A is a front surface in which the modular jacks 2A to 2H are juxtaposed, the juxtaposed surface 3A is hereinafter referred to as a front surface 3A. The front surface 3A is formed in a rectangular shape when viewed from the front. The modular jacks 2 </ b> A to 2 </ b> H are collectively arranged near one side of the front surface 3 </ b> A of the electronic device 3. In the present embodiment, eight modular jacks 2A to 2H are arranged side by side on the front surface 3A.

  The cover 1 is configured to cover all of the modular jacks 2A to 2H. The cover 1 includes a main body, and the main body includes a mounting portion 4 and an extension portion 5. The cover 1 is formed in a box shape as a whole. Specifically, the cover 1 is formed in the shape of an empty square frustum. The cover 1 is made of a hard synthetic resin.

  As shown in FIGS. 1 and 6, the mounting portion 4 is a portion that is mounted in direct contact (contact) with the electronic device 3 (in this case, the front surface 3 </ b> A). The mounting portion 4 has a shape corresponding to the edge shape of the front surface 3A. In this case, as shown in FIGS. 1 and 2, the mounting portion 4 is formed in a rectangular frame shape as a whole from an upper frame portion, a lower frame portion, and a pair of left and right horizontal frame portions. In the mounting portion 4, the outer surfaces of the upper frame portion, the lower frame portion, and the pair of left and right horizontal frame portions are formed as flat surfaces.

  The vertical height of the mounting portion 4 is set substantially equal to the vertical height of the front surface 3 </ b> A of the electronic device 3. The left-right width of the mounting portion 4 is set to a width including at least all of the modular jacks 2A to 2H. In other words, the left-right width of the mounting portion 4 is set so as to include the left-right width of the region where the modular jacks 2A to 2H are formed. In this case, the left and right widths of the mounting portion 4 are set so as not to cover a power jack (not shown) located on one side of the front surface 3A of the electronic device 3.

  As shown in FIGS. 1, 2, and 5, the extension portion 5 is formed to extend from the mounting portion 4. Specifically, the extension portion 5 is extended forward from the mounting portion 4 (toward the direction away from the modular jacks 2A to 2H) and is formed in a quadrangular frustum shape. The extension 5 includes a flat upper wall 6, a lower wall 7, and left and right side walls 8 and 9. The extension 5 further includes a front wall 10.

  The upper wall 6 is formed to be inclined downward toward the front. The lower wall 7 is formed so as to be inclined upward toward the front. The side walls 8 and 9 are inclined so as to approach each other toward the front. The front wall 10 is surrounded on all sides by front end portions of the upper wall 6, the lower wall 7, and the side walls 8 and 9. The front wall 10 is parallel to the front surface 3 </ b> A of the electronic device 3 in a state where the cover 1 is attached to the electronic device 3. By these walls, the extension portion 5 is formed in a quadrangular frustum shape that is narrowed toward the tip.

  As shown in FIGS. 1, 3, and 4, a narrow opening 13 is formed in the front wall 10. The narrow opening 13 is set to a size that allows the cord 12 connected to the modular plug 11 to be inserted and prevents the modular plug 11 from being inserted (prevents the user's fingers from being inserted). Further, the modular plug 11 cannot be inserted into the narrow opening 13 regardless of the direction of the modular plug 11. The narrow opening 13 is formed so as to pierce a part of the front wall 10 instead of the entire front wall 10.

  In the present embodiment, the narrow opening 13 is distributed to the left and right of the front wall 10 and is formed in an elongated elliptical shape having a major axis in the left-right direction. The space between the narrow mouth portions 13 is a separation portion 14 of the front wall 10. The side portions and the upper and lower portions of each narrow mouth portion 13 are the edge portions 15 of the front wall 10. As shown in FIGS. 2, 4, and 5, a reinforcing rib 16 is formed at a position corresponding to the back side of the separating portion 14.

  As shown in FIGS. 2, 3, 4, and 6, the side walls 8 and 9 are formed with a screw hole 18 through which a screw 17 that is a fixture is inserted, and a guide path 19 that guides the screw 17 to the screw hole 18. Yes. Boss portions 20 for forming screw holes are formed on the inner surfaces of the side walls 8 and 9, and the screw holes 18 are formed in the boss portions 20. The screw hole 18 is formed in the side walls 8 and 9 along the front-rear direction. The guide path 19 is formed on the surfaces of the side walls 8 and 9. Since the side walls 8 and 9 are inclined, the substantial distance through which the screw 17 is inserted can be shortened.

  As shown in FIG. 7, the main body is configured by combining (assembling) a plurality of divided members. In the present embodiment, the two divided members are integrally formed by combining one divided member and the other divided member. In this case, the dividing member includes an upper dividing member 21 and a lower dividing member 22. As shown in FIGS. 1 and 7, the split surfaces 23, 24, and 25 of the upper split member 21 and the lower split member 22 are continuously formed across the mounting portion 4, the side walls 8 and 9, and the front wall 10. ing.

  The dividing surface 23 of the mounting portion 4 has a stepped surface shape in which horizontal surfaces arranged in front and back are continuous with each other on a vertical surface. As shown in FIGS. 2, 4, and 7, on the back surface of the mounting portion 4, the contact portion 26 is formed so as to be in contact with the boss portion 20 from behind to constitute a part of the screw hole 18 (18 a). ing. The back surface of the contact portion 26 is flush with the back surface of the mounting portion 4 (the back surface of the contact portion 26 is a part of the back surface of the mounting portion 4). The dividing surface 23 of the mounting portion 4 is formed following the side surface shape of the contact portion 26.

  The dividing surfaces 24 of the side walls 8 and 9 are horizontal surfaces in the front-rear direction. Since the dividing surface 24 is continuous with the front horizontal surface of the dividing surface 23 of the mounting portion 4, the dividing surface 24 is formed at a position below the side walls 8 and 9. The dividing surface 25 at the edge 15 of the front wall 10 is formed by a combination of a horizontal plane arranged on the left and right and a vertical plane that is continuous between the horizontal planes. The dividing surface 25 in the separation portion 14 of the front wall 10 is a horizontal plane arranged at the center in the vertical direction. The narrow opening 13 is arranged at the center position in the vertical direction of the front wall 10. That is, the dividing surface 25 is also a surface that divides the narrow opening 13 at the center position in the vertical direction.

  As shown in FIGS. 4 and 5, the reinforcing rib 16 is composed of a combination of an upper rib 27 formed on the upper divided member 21 and a lower rib 28 formed on the lower divided member 22. The reinforcing rib 16 is positioned at the center in the left-right direction of the cover 1. The upper rib 27 is integrally provided with an upper rib main body 29 and a protrusion 30 that is a fitting portion. The upper rib body 29 is formed on the back surface (inner surface) of the upper wall 6 of the upper split member 21 in a wall shape protruding downward in the front-rear direction along the inclined direction of the back surface. However, the upper rib main body 29 does not reach the mounting portion 4. The protrusion 30 is formed near the lower surface of the back surface of the front wall 10 and protrudes rearward from the back surface. The protrusion 30 is formed in a cylindrical shape.

  The lower rib 28 is integrally provided with a lower rib main body 31 and a hole that is a fitted portion that is fitted to the protrusion 30. The lower rib main body 31 is formed on the back surface (inner surface) of the lower wall 7 of the lower dividing member 22 in a wall shape protruding upward in the front-rear direction along the inclined direction of the back surface. However, the lower rib body 31 does not reach the mounting portion 4.

  The lower rib body 31 is set to be higher than the height of the upper rib body 29 from the back surface of the upper wall 6 and the height of the lower rib body 31 from the back surface of the lower wall 7. The hole portion is formed on the back surface of the front wall 10, and an extension portion 33 extending upward from the lower rib body 31 and a fitting hole 34 extending further upward from the extension portion 33 and fitting into the protrusion 30 are formed. A perforated piece 35. The perforated piece 35 is a portion that is fitted to the protrusion 30 from behind. The front-rear direction length of the fitting hole 34 is set longer than the front-rear direction length of the protrusion 30.

  As shown in FIGS. 1 and 6, the cover 1 and the electronic device 3 are attached to each other via an attachment structure. The mounting structure is provided separately on the cover 1 side and the electronic device 3 side. Specifically, the attachment structure includes a screw hole 18 on the cover 1 side, a screw 17 inserted into the screw hole 18 from the front to the rear, and an attachment hole 36 on the electronic device 3 side.

  The mounting hole 36 is formed further outside the modular jacks 2A and 2H at the left and right outer ends. The mounting hole 36 is disposed substantially at the center in the vertical direction of the front surface 3 </ b> A. Thus, the electronic device 3 is provided with the mounting hole 36 as a mounting structure of the cover 1.

  The electronic device 3 and the cover 1 having the above-described configuration are preferably sold as a set product at a store such as a mass retailer, or used for mail order sales. As shown in FIG. 1, the cover 1 having the above-described configuration covers the modular jacks 2A to 2H in a state where the modular plug 11 is inserted into the modular jacks 2A to 2H (for example, the modular jack 2A to be used) of the electronic device 3. In this way, the electronic device 3 is attached.

  That is, as shown in FIG. 7, the cord 12 connected to the modular plug 11 inserted into the modular jack 2 </ b> A in a state where the upper divided member 21 and the lower divided member 22 are not yet assembled is connected to the upper divided member. 21, the upper divided member 21 and the lower divided member 22 are assembled together so that the narrow mouth portion 13 is formed after being aligned with a corresponding portion (see reference numeral 13A) of the narrow mouth portion 13 in the lower divided member 22. This is attached to the electronic device 3.

  More specifically, in a state where the modular plug 11 is inserted into the modular jack 2A, the cord 12 is aligned with the corresponding portion 13A of the narrow portion 13 of the upper divided member 21 and the lower divided member 22, and the upper divided member The abutment portion 26 of the lower division member 22 abuts the boss portion 20 of the upper division member 21 from the rear so that the division surface 21 and the division surface of the lower division member 22 abut, and the screw hole 18 (18a). Further, the upper divided member 21 is further divided from the rear side so that the fitting holes 34 of the perforated pieces 35 of the lower divided member 22 are fitted to the protrusions 30 of the upper divided member 21 so that the communication is established. The member 22 is assembled.

  When the protrusion 30 and the fitting hole 34 are fitted, the upper divided member 21 and the lower divided member 22 are assembled and configured as the cover 1. When the upper divided member 21 and the lower divided member 22 are assembled to form the cover 1, the narrow opening 13 is formed in the front wall 10 of the cover 1, and only the cord 12 is inserted into the narrow opening 13.

  The cover 1 is attached to the electronic device 3 on the front surface 3A of the electronic device 3 using an attachment structure. Specifically, the screw 17 is inserted into the screw hole 18 on the cover 1 side from the front to the rear, and this is screwed into the mounting hole 36 on the electronic device 3 side, whereby the cover 1 is attached to the electronic device 3. It can be firmly and firmly attached to the front surface 3A without any gap (can be fixed). That is, the cover 1 can be removed from the front surface 3 </ b> A of the electronic device 3 only by loosening the screw 17.

  The vertical height of the mounting portion 4 is set substantially equal to the vertical height of the front surface 3 </ b> A of the electronic device 3. The left and right width of the mounting portion 4 is set so as to include all of the modular jacks 2A to 2H and to include the left and right widths of the region portion where the modular jacks 2A to 2H are formed. For this reason, when the cover 1 is attached to the front surface 3A of the electronic device 3, the cover 1 is put on all the modular jacks 2A to 2H.

  When the modular plug 11 is inserted only into the modular jack 2A and the modular plug 11 is not inserted into the other modular jacks 2B to 2H, the other modular plug 11 is inserted into the modular jacks 2B to 2H. There is a possibility of wearing.

  However, the cover 1 covers all the modular jacks 2A to 2H, and the narrow mouth portion 13 can insert the cord 12 connected to the modular plug 11 and cannot insert the modular plug 11 (the finger of the user's finger). The size is set to prevent insertion. For this reason, even if the modular jacks 2B to 2H into which the modular plug 11 is not inserted exist, the modular plug 11 cannot be inserted into the modular jacks 2B to 2H. Therefore, it is possible to prevent the modular plug 11 from being inserted into the modular jacks 2B to 2H and used illegally.

  The cover 1 is formed in a box shape from a hard synthetic resin, and a reinforcing rib 16 is formed at a position corresponding to the back side of the separation portion 14. Further, the cover 1 is inserted into the screw hole 18 on the cover 1 side from the front to the rear, and is screwed into the mounting hole 36 on the electronic device 3 side, so that the cover 1 is attached to the front surface 3A of the electronic device 3. It is tightly and firmly installed without any gaps.

  According to such a configuration, the cover 1 itself can sufficiently resist an external force, so that it is difficult to be broken or damaged, and it is not easy to remove the cover 1 from the electronic device 3. Accordingly, even if there are modular jacks 2B to 2H into which the modular plug 11 is not inserted, the cover 1 cannot be destroyed or removed, and the modular plug 11 cannot be inserted into the modular jacks 2B to 2H. Therefore, it can suppress that the modular plug 11 is inserted in modular jack 2B-2H and used illegally.

  In addition, the distance from the narrow opening 13 to the modular jacks 2B to 2H is increased by the amount that the main body protrudes forward from the juxtaposed surface 3A. For this reason, it is difficult to access the modular jacks 2B to 2H which are not used.

  Further, the narrow opening 13 formed in the front wall 10 of the cover 1 is sized to prevent the insertion of a human finger. For this reason, the modular plug 11 already inserted into the modular jack 2A cannot be removed from the modular jack 2A.

  The extension part 5 is formed in a truncated pyramid shape, and the front side is concave. The area of the front wall 10 is smaller than that of the mounting part 4, and the periphery of the narrow part 13 is an edge part 15. In such a form, the edge 15 becomes very strong from the relationship between the area and thickness (because the ratio of area to thickness is close). For this reason, it is difficult to pry open so that the narrow mouth part 13 becomes wide, and also in this respect, the modular plug 11 can be prevented from being used illegally by being inserted into the modular jacks 2B to 2H.

  In the cover 1 of the present embodiment, the cord 12 is held by the narrow opening 13 (the edge of the narrow opening 13) while being inserted through the narrow opening 13. The narrow opening 13 is at the tip of the extension 5. That is, the cord 12 is held at a position separated from the modular plug 11 by substantially the front and rear width of the cover 1, and the movable range of the cord 12 in the vertical and horizontal directions is an area (range) of the narrow mouth portion 13. Therefore, since the connection part with the modular plug 11 in the cord 12 can be largely bent (extremely bent), the connection part with the cord 12, particularly the modular plug 11, can be protected from damage.

  Further, the cover 1 is attached to the electronic device 3 so as to cover the modular jacks 2A to 2H. For this reason, it is possible to prevent surrounding dust from adhering to the modular jacks 2A to 2H (modular jacks not particularly used).

  In the above-described method of using the cover 1, an example has been described in which the modular plug 11 is inserted only into the modular jack 2 </ b> A and the cord 12 is inserted and held through the narrow opening 13. However, the cover 1 in which the modular plug 11 is inserted into each of the modular jacks 2 </ b> A to 2 </ b> H and the cords 12 (a plurality of cords 12) of the modular plug 11 are inserted and held in the narrow portion 13. Usage is also possible. In such a case, the modular plug 11 can be distributed and inserted into each narrow opening 13.

  If the modular plug 11 is inserted into the plurality of modular jacks 2A to 2H without attaching the cover 1 according to the present embodiment, the cords 12 are likely to be messy. However, in the cover 1 according to the present embodiment, the cords 12 are collected in a limited area called the narrow opening 13. For this reason, it can prevent that the several code | cord | chord 12 becomes a messy state.

  Next, with reference to FIG. 8 and FIG. 9, the cover 1 which concerns on 2nd embodiment of this invention is demonstrated. The parts of the cover 1 according to the second embodiment that are different from the cover 1 according to the first embodiment are the shape of the narrow opening 13, the height of the entire cover 1, and the reinforcing rib 16. About the structure of another part, the code | symbol same as 1st embodiment is attached | subjected and description is not repeated.

  The narrow opening 13 formed in the cover 1 of the second embodiment is distributed to the left and right, and each edge is formed in a zigzag shape with the left-right direction as the longitudinal direction when viewed from the front. A separation portion 14 is formed between the narrow mouth portions 13, and an edge portion 15 is formed around the narrow mouth portion 13. Each narrow opening 13 is set to a width that allows the cord 12 to be inserted and the modular plug 11 not to be inserted. A plurality of pointed portions 13a are formed at predetermined intervals on the upper edge and the lower edge of each narrow mouth portion 13. Even if the edge is formed in a zigzag shape with the left-right direction as the longitudinal direction, the modular plug 11 cannot be inserted into the narrow opening 13 regardless of the direction of the modular plug 11.

  The height of the cover 1 in the second embodiment is set higher than the height of the cover 1 in the first embodiment. This is because the height of the electronic device 3 to which the cover 1 is attached in the second embodiment is higher than the height of the electronic device 3 in the first embodiment.

  In the first embodiment, the lower rib body 31 is set to be higher than the upper rib body 29 between the height of the upper rib body 29 of the upper rib 27 and the height of the lower rib body 31 of the lower rib 28 in the reinforcing rib 16. Has been. On the other hand, in the second embodiment, as shown in FIG. 9, the height of the upper rib body 29 of the upper rib 27 and the height of the lower rib body 31 of the lower rib 28 are set to be substantially equal. ing. This is because the height of the cover 1 in the second embodiment is set higher than the height of the cover 1 in the first embodiment. Even if the protrusions 30 are provided, the height of the upper rib body 29 can be increased by the height of the cover 1. The strength of the entire cover 1 can be ensured by the height of the upper rib body 29.

  Since the narrow mouth portion 13 of the cover 1 in the second embodiment is formed in a horizontally long zigzag shape, if a finger is to be inserted into the narrow mouth portion 13, the finger is placed on the sharp end portion 13 a of the narrow mouth portion 13. In this case, it is difficult to insert fingers into the narrow mouth portion 13, and the modular plug 11 can be prevented from being used illegally by being inserted into the modular jacks 2B to 2H.

  Next, with reference to FIG. 10 thru | or FIG. 12, the cover 1 which concerns on 3rd embodiment of this invention is demonstrated. The portion of the cover 1 according to the third embodiment that is different from the cover 1 of the first embodiment is the configuration of the left and right width of the entire cover 1, the narrow mouth portion 13, and the reinforcing rib 16. For this reason, the other components are denoted by the same reference numerals, and description thereof will not be repeated.

  The left-right width of the cover 1 in the third embodiment is set longer than the left-right width of the first cover 1 as a whole. This is because the left-right width of the electronic device 3 to which the cover 1 is attached in the third embodiment is longer than the left-right width of the electronic device 3 in the first embodiment. Specifically, on the front surface 3A of the electronic device 3 in the present embodiment, although not shown, twelve modular jacks arranged in the left-right direction are arranged in two upper and lower stages, for a total of 24 modular jacks. It has.

  As shown in FIGS. 10 and 11, three narrow mouth portions 13 are formed on the front wall 10. Since the shape of each narrow opening 13 is the same as that of the narrow opening 13 in the cover 1 of the second embodiment, the same reference numerals are given and description thereof is not repeated. A separation portion 14 is formed between the narrow openings 13, and an edge 15 is formed around the narrow openings 13.

  In the cover 1 according to the third embodiment, two reinforcing ribs 16 are formed as shown in FIG. These reinforcing ribs 16 are arranged at positions that divide the left-right width of the cover 1 into approximately three equal parts. The basic configuration of each reinforcing rib 16 is the same as that of the first embodiment. However, as shown in FIG. 12, the upper rib main body 29 of the upper rib 27 is similar to the second embodiment in the cross-sectional shape. And the height of the lower rib body 31 of the lower rib 28 are set substantially equal.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, in each of the above embodiments, the cover 1 is shown as an example of a truncated pyramid shape that sags toward the tip side. However, as shown in FIGS. 13 and 14, the extension 5 may be formed in a rectangular parallelepiped box shape protruding forward from the mounting portion 4. In this case, the narrow opening 13 is set to such a size that the cord 12 can be inserted and the modular plug 11 and fingers cannot be inserted.

  The attachment structure of the cover 1 and the electronic device 3 is not particularly limited. In the cover 1 shown in FIGS. 13 and 14, the mounting portion 4 is formed at the base end portion of the extension portion 5 in a rectangular frame shape that protrudes outside the extension portion 5, and the screw 17 is formed at the mounting portion 4. Alternatively, the screw hole 18 may be inserted and screwed into a mounting hole (not shown) formed in the front surface 3A of the electronic device 3. Further, although not shown, the mounting structure may be a fitting hole in which the convex portion and the screw hole are fitted instead of the screw 17 and the screw hole 18.

  As yet another embodiment, the mounting holes are formed on the upper and lower surfaces of the electronic device, not on the front surface of the electronic device, and the screw holes are arranged rearward so that the upper and lower portions of the mounting portion are not the side walls of the cover and reach the upper and lower surfaces The cover can be attached to the electronic device by extending and forming the extension portion, and inserting and screwing the screw into the screw hole and the attachment hole. Even in this case, the cover is covered with the parallel arrangement surface (modular jack) of the electronic device, but the direct mounting surface of the cover is the upper surface and the lower surface of the electronic device. That is, the cover may be configured to be attached to the other surface of the electronic device on the condition that the cover is placed on one or a plurality (including all) of modular jacks that are not used.

  In each of the above embodiments, the cover (main body) is formed in a box shape protruding forward from the front surface of the electronic device. However, although not shown, the cover may be formed in a box shape in which the tip side (narrow mouth side) is extended upward or sideward. In each said embodiment, although the narrow opening part was formed in the front end side of an extension part, a narrow opening part can also be formed in the front-back direction middle part (for example, upper wall and lower wall) of an extension part, for example. The cover 1 is not limited to a combination of split members that divide the narrow opening 13 in the horizontal direction, and may be configured by a combination of split members that split the narrow opening 13 in the vertical direction.

  The electronic device is not limited to a rectangular parallelepiped shape, and can be applied to an electronic device whose front surface is a curved surface, for example. In this case, if the mounting portion is shaped to follow the curved surface, the same effects as those of the above embodiments can be obtained. And such an electronic device is not limited to a hub, The cover of this invention is applicable if it is an electronic device provided with the modular jack arranged in parallel by two or more.

  Further, a covering member that covers the narrow mouth portion so as to be freely opened and closed can be provided. Specifically, the covering member is formed of a deformable material such as synthetic rubber, and when the cord is passed through the narrow opening, the covering member is elastically deformed by being pushed by the cord and partially opens the narrow opening. The other parts can also be configured to be closed. According to this configuration, since most of the narrow mouth portion is closed, it is possible to effectively prevent dust from adhering to the modular jack.
