Description

Technical Field

[0001] The present invention relates to a communication device formed by removably housing a communication unit such as a media converter in a housing, and more particularly to a communication device capable of simply and firmly fixing the communication unit.

[0002] A media converter, as a communication unit, has a function of converting and connecting different media (such as metal cables and optical fiber cables) to each other for data, and with the development of communication technology, its applications have been rapidly expanding. Communication units such as media converters are housed in a housing of an integrated chassis according to specifications required by users and used as an entire communication device.

[0003] Such a communication device is required to be able to smoothly insert and remove a communication unit such as a media converter into and out of a slot, and at the same time, firmly and stably fix it.

[0004] In conventional communication devices, efforts have been made to improve the ease of fixing and the fixing strength of communication units such as media converters to be housed.

[0005] For example, a conventional communication device is a storage device capable of housing a plurality of communication devices connected to a transmission medium, and includes a support portion fixed to an external frame, and a mounting portion that removably houses the communication device and is movable with respect to the support portion. The mounting portion has a first surface and a second surface different from the first surface, and the transmission medium can be connected to the communication device through the first and second surfaces of the mounting portion. There is a storage device in which mechanical engagement such as fitting and fixing to a screw hole on the bottom surface of the media converter or fitting the media converter between opposing bridge portions biased in the left-right direction is shown (see Patent Document 1).

[0006] Furthermore, as an example of a conventional communication device, there is an assembled chassis having a chassis housing having a plurality of slots for storing card modules, the chassis housing is provided with a fixing part for fixing the card module which can be moved from a position in which the card module stored in the slot is fixed to a position in which the card module can be removed from the slot, a screw attached to the fixing part which is detachably screwed into the chassis housing and fixes the fixing part itself to the chassis housing in the position in which it is fixed, and a spring which applies a biasing force in the retraction direction between the chassis housing and the fixing part when the screw attached to the fixing part is screwed into the chassis housing, and the fixing part is moved to a position in which the card module can be removed from the slot by the biasing force of the spring when the screw attached to the fixing part is detached from the chassis housing (see Patent Document 2).

[0008] However, conventional media converters, such as those described in Patent Document 1, are fixed by screwing them into screw holes on the bottom surface of the media converter. However, screwing requires cumbersome work such as using a screwdriver, which places a heavy burden on the operator. In addition, some media converters, as described in Patent Document 1, are fitted between opposing bridge sections that are biased in the left-right direction. However, it is difficult to confirm whether the media converter is properly fitted, and stable strength cannot be obtained because the fixing relies on the biasing force of the bridge section.

[0009] Furthermore, some conventional media converters, as shown in Patent Document 2, include a screw attached to the fixing part and a spring that applies a biasing force in the retraction direction between the chassis housing and the fixing part when the screw attached to the fixing part is screwed into the chassis housing. However, this requires complicated work such as screwing, which is burdensome. In addition, the complex configuration using multiple parts that combine screws and springs results in high manufacturing costs and repair costs in the event of a malfunction.

[0010] The present invention was made to solve the aforementioned problems, and aims to provide a communication device with a simple configuration that can easily and securely fix communication units such as media converters. [Means for solving the problem]

[0011] The communication device according to the present application comprises a housing portion formed in the shape of a rectangular parallelepiped and having an opening on the front surface of the rectangular parallelepiped, and a communication unit portion formed from a rectangular parallelepiped container in which communication components are housed, and which is slidably inserted into at least the upper and lower inner surfaces of the housing portion and mounted inside the housing portion, wherein the communication unit portion has a projection that can be extended and retracted from the upper surface of the container, and is provided with an operating part for operating the extension and retraction of the projection, and the housing portion is provided with a locking part disposed at a position corresponding to the projection of the operating part when the communication unit portion is mounted inside the housing.

[0012] As described above, the communication device according to the present invention comprises a housing portion formed in the shape of a rectangular parallelepiped and having an opening on the front surface of the rectangular parallelepiped, and a communication unit portion formed from a rectangular parallelepiped container in which communication components are housed, and which is slidably inserted into at least the upper and lower inner surfaces of the housing portion and mounted inside the housing portion, wherein the communication unit portion has a projection that can be extended and retracted from the upper surface of the container and is provided with an operating portion for operating the extension and retraction of the projection, and the housing portion is provided with a locking portion disposed at a position corresponding to the projection of the operating portion when the communication unit portion is mounted inside the housing, so that the operating portion of the communication unit portion is made of an elastic material, the communication unit portion including the projection of the operating portion can be smoothly inserted into the housing portion, and because the projection of the operating portion is biased upward, the communication unit portion is securely locked to the locking portion on the upper surface of the container of the communication unit portion and mounted inside the housing portion, the communication unit portion can be easily and firmly attached and detached with a simple configuration.

[0013] The communication device according to the present invention is configured such that, if necessary, the operating section is formed from a long elastic body, one end of the elastic body is bent into a hook shape to form a handle, and a projection is formed in the middle of the elastic body, the handle is exposed on the front of the container, and the other end of the elastic body is fixed to the back of the container.

[0014] As described above, the operating part is formed from a long elastic body, with one end of the elastic body bent into a hook shape to form a handle, and a projection is formed in the middle of the elastic body, exposing the handle to the front of the container, and the other end of the elastic body fixed to the back of the container. With the communication unit installed inside the housing, pushing the handle downwards causes the projection of the operating part to move downwards in conjunction with the other end of the fixed elastic body acting as a fulcrum, and as a result the projection of the operating part separates from the locking part, releasing the locking by the locking part. With the lock released, the communication unit can be easily removed by pulling the handle forward, and the communication unit can be easily and securely attached and detached by a simple operation using the handle.

[0015] The communication device according to the present invention is configured such that the elastic body is formed from a plate containing a leaf spring or a spring spring, as necessary. Since the elastic body is formed from a plate containing a leaf spring or a spring spring, the operating part is made of a single plate with a biasing force, so that when the handle is pushed downward, it becomes the point of force application, and in conjunction with this, the other end of the elastic body fixed to the back of the container becomes the fulcrum and supports it, and in conjunction with this, the operating part becomes the point of action and separates the elastic body from the locking part, and the locking by the locking part is easily released, so that the communication unit can be attached and detached easily and firmly using a simple pushing operation with the handle, more efficiently.

[0016] The communication device according to the present invention has a handle that, if necessary, has a cross-section that is U-shaped upwards or arc-shaped downwards. In this way, because the handle has a cross-section that is U-shaped upwards or arc-shaped downwards, the communication unit can be removed from the housing by a downward pushing operation using the handle and a pulling operation that pulls the communication unit out from the housing towards the front, and the communication unit can be stored inside the housing by a pushing operation in the depth direction using the handle. Thus, with a simple configuration and simple operation using the handle, the communication unit can be easily and securely attached and detached.

[0017] In the communication device according to the present invention, the communication unit is a media converter as needed. Since the communication unit is a media converter, the attachment and detachment of the media converter, which is used by attaching and detaching it, can be performed simply and smoothly by locking the operation unit and the locking unit together, and the communication unit, which is a media converter, can be attached and detached and fixed easily and securely.

Mode for Carrying Out the Invention

[0019] (Embodiment) As shown in FIGS. 1(a) and (b), the communication device according to the embodiment of the present invention includes a housing portion 1 formed in a rectangular parallelepiped shape and having an opening 11 on the front surface of the rectangular parallelepiped shape, and a rectangular parallelepiped-shaped container in which communication components 23 are housed. The communication unit portion 2 is formed by a rectangular parallelepiped-shaped container and is slidably inserted into at least the upper and lower surfaces of the inner surface of the housing portion 1 and is mounted inside the housing portion 1. The communication unit portion 2 has a protruding piece 21a that can protrude and retract from the upper surface of the container, and includes an operation portion 21 for operating the protrusion and retraction of the protruding piece. The housing portion 1 includes a locking portion 14 disposed at a position corresponding to the protruding piece 21a of the operation portion 21 when the communication unit portion 2 is mounted inside the housing.

[0020] Also, the materials of the housing portion 1 and the communication unit portion 2 are not particularly limited, but it is preferable that they be made of metal. Although this metal is not particularly limited, for example, a material made of a magnetic shielding material can be used. Although this magnetic shielding material is not particularly limited, for example, iron or aluminum can be used.

[0021] As shown in FIG. 1(a), the front surface of the housing portion 1 is in a state where the opening 11 is open. As shown in FIG. 1(b), the communication unit portion 2 is inserted into the opening 11. As shown in FIG. 1(c), a communication device in which the communication unit portion 2 is mounted inside the housing portion 1 is formed. Also, it is possible to take out the communication unit portion 2 from the housing portion 1 as necessary, such as when replacing the communication unit portion 2.

[0022] Furthermore, a locking portion 14 is provided on the upper surface of the inner surface of the housing portion 1. The method of providing the locking portion 14 is not particularly limited. For example, it may be directly provided on the upper surface of the inner surface of the housing portion 1. Alternatively, as shown in Figure 2(a), a metal plate-like intermediate plate 1a may be provided on the upper surface of the inner surface of the housing portion 1, and the locking portion 14 may be provided as a through-hole that penetrates the intermediate plate 1a. The shape of the locking portion 14 is not particularly limited as long as it is a shape that can lock onto the projection 21a that protrudes from the upper surface of the container of the communication unit portion 2. For example, it may be a hole. The shape of this hole is not particularly limited, but it may be configured not to penetrate the upper surface of the housing portion 1. For example, even when the locking portion 14 is provided as a through-hole using the intermediate plate 1a described above, the upper surface of the housing portion 1 can be formed by covering the upper surface of the intermediate plate 1a with a metal top cover 1b, as shown in Figures 2(a) and (b). As a result, the locking portion 14 is not exposed to the outside of the housing portion 1, allowing for a simple, uncluttered, and flat appearance.

[0023] When the communication unit 2 is installed inside the housing 1 through the opening 11, as shown in Figure 1(b), a locking portion 14, for example, having a hole shape, locks onto the projection 21a of the operating portion 21 on the upper surface of the inner surface of the housing 1. In other words, neither the locking portion 14 nor the projection 21a of the operating portion 21 is exposed to the outside, and a simple and uncluttered appearance is maintained regardless of whether the communication unit 2 is inserted or removed.

[0024] The number of openings 11 in the housing 1 is not particularly limited, but may be one or multiple depending on the application. For example, it can be configured to have two openings 11 side by side.

[0025] This communication unit 2 can be inserted into one of the two openings 11 of the housing 1, for example, as shown in Figure 1(c) above. The opening 11 of the housing 1 into which the communication unit 2 is not inserted can be used as an empty slot, and a dummy communication unit can be inserted there. Alternatively, for example, it can be inserted into both of the two openings 11 of the housing 1.

[0026] Depending on the application, the communication unit 2 may include, for example, a cable terminal 23a disposed on the front of the container so as to be connectable to an optical cable, as shown in Figure 3(a), and a metal magnetic shielding section 22a disposed on the top and sides of the container.

[0027] The material of the magnetic shielding section 22a is not particularly limited, but for example, metallic copper can be used. When the communication unit section 2 is inserted and supported and fixed, the entire device exhibits a magnetic shielding function, and without requiring any extra external components, it is possible to block external magnetic noise and block the emission of internal magnetic noise, thereby creating a higher quality communication environment.

[0028] As shown in Figure 3(a), the communication unit 2 includes a projection 21a made of an elastic material on the upper surface of the container. The type of elastic material is not particularly limited, but for example, a spring can be used. There may be one projection 21a or multiple projections 21a. For example, two projections 21a can be arranged side by side on the upper surface of the container.

[0029] The communication unit 2 is not particularly limited as long as it is a removable communication device, but for example, it can be a media converter. The operation of attaching and detaching the media converter, which is used by attaching and detaching it, can be performed simply and smoothly by locking the operation unit 21 and the locking unit 14 together, and the media converter can be attached and detached and fixed easily and securely without using a complex fixing mechanism like in the past.

[0030] As shown in Figure 3(a), the operating unit 21 is attached to the inner surface of the top surface of the communication unit case 22, which is composed of the top surface and left and right sides of the container that constitutes the communication unit section 2. The communication unit section 2 is formed by housing the communication component 23 inside the communication unit case 22.

[0031] As shown in Figure 3(a), the communication unit case 22 includes a through hole 22b disposed on the inner surface of the top surface through which the projection 21a passes, a screw hole 22c disposed on the inner surface of the top surface that can be screwed into the operating part 21, a cable terminal 23a disposed on the front side that can be connected to an optical cable or the like, and a metal magnetic shield part 22a disposed on the outer surface of the top and side.

[0032] More preferably, as shown in Figures 3(b) and (c), the operating section 21 is formed from an elongated elastic body, with one end 21A of the elastic body bent into a hook shape to form a handle 21b, and the projection 21a is formed in the middle of the elastic body, so that the handle 21b is exposed on the front of the container, and the other end 21B of the elastic body is fixed to the back of the container.

[0033] The elongated elastic body constituting this operating section 21 is not particularly limited, but for example, it can be formed from a leaf spring or a plate containing a spring.

[0034] A leaf spring is a metal plate-like body with spring properties. It can be formed with a simple structure using a single metal plate, and it is also easy to shape the protrusion 21a and the handle 21b into a hook-like bend, making it more suitable in terms of cost and maintenance. A plate containing a spring is a plate containing a coil-shaped spring.

[0035] At one end 21A of the operating section 21, the handle 21b is exposed on the front of the container. The operator can use this handle 21b as a grip when inserting or removing the communication unit. Its shape is not particularly limited as long as it is bent in a hook shape, but more preferably, as shown in Figure 3(b), the handle 21b has an upward-facing U-shape, or as shown in Figure 3(c), it has a downward-facing arc-shaped cross section.

[0036] Thus, the handle 21b, having an upward-facing U-shape or downward-facing arc-shaped cross-section, allows the operator to pull the communication unit from the front towards them, push it away from them, and even push it downwards. All of these operations can be performed with a single shape, resulting in a compact design and simple operation.

[0037] In other words, by using the handle 21b to push downwards and pulling out the communication unit 2 from the housing towards the front, the communication unit 2 can be removed from the housing, and by using the handle 21b to push in depth into the housing, the communication unit 2 can be stored inside the housing. Thus, with a simple configuration and simple operation using the handle 21b, the communication unit can be easily and securely attached and detached.

[0038] In the middle section of the operating section 21, a projection 21a made of an elastic material is provided on the upper surface. As shown in Figure 4(a), this projection 21a is formed as a protruding body, and it moves in and out by passing through the hole 22b of the communication unit case 22 in the vertical direction. The shape of this projection 21a is not particularly limited, but for example, it is preferable that the height of one end 21A of the operating section 21 is higher than the height of the other end 21B. As a result, when the projection 21a is locked into the locking section 14, the height of the one end 21A of the elastic material functions as a stopper, preventing the communication unit, once fixed inside the housing section 1, from flying out the opening 11 of the housing section 1 to the front, and allowing the communication unit to be fixed inside the housing section 1 more stably.

[0039] At the other end 21B of the operating section 21, as shown in Figure 4(b), the operating section 21 is fixed to the rear side of the communication unit case 22. This fixing is not particularly limited, but for example, it can be fixed by screwing it into the screw hole 22c of the communication unit case 22. With this fixing, the operating section 21, which is made of a leaf spring or the like, has its upper surface fixed at the other end 21B of the operating section 21, and thus has an upward biasing force. There may be one projection 21a or multiple projections 21a.

[0040] As shown in Figure 5(a), the projection 21a of the communication unit 2 is made of an elastic body having an upward biasing force F. Therefore, when not subjected to external forces, the projection 21a remains in a state of protruding through the through hole 22b due to the upward biasing force F.

[0041] On the other hand, as shown in Figure 5(b), when a downward pressing force F1 is applied from the handle 21b, the elastic force causes the fixing portion 21c to act as a fulcrum, and with the downward pressing force A as the point of application, the projection of the protruding piece 21a is pushed downward as the point of application, sinking downward from the through hole 22b and transitioning to a flat state where it does not protrude from the through hole 22b.

[0042] Subsequently, when the downward pressing force F1 from the handle 21b ceases to be applied, only the constantly acting upward biasing force F remains on the operating part 21. The projection of the protrusion 21a is then pushed back upward by its elastic force, passing through the through hole 22b upward and protruding, restoring it to its original state as shown in Figure 5(a).

[0043] The shape of the projection 21a is not particularly limited, but for example, as shown in Figure 6(a), it can be configured to have an upright portion 21C that stands upright at one end 21A of the operating portion 21, a sloping portion 21D that inclins toward the other end 21B, and a second upright portion 21E that stands upright at the other end 21B. In this case, once the projection 21a is fixed by the locking portion 14 of the housing portion 1, the height of the upright portion 21C functions as a stopper, preventing it from protruding out to the front side from the opening 11 of the housing portion 1. At the same time, the sloping portion 21D facilitates insertion and removal from the locking portion 14, and the second upright portion 21E can provide stable fixing as a stopper in the depth direction when the locking portion 14 is fixed.

[0044] Furthermore, as shown in Figure 6(b), for example, the shape of the projection 21a can be configured to have an upright portion 21C that stands upright at one end 21A of the operating portion 21, and a sloping portion 21D that slopes toward the other end 21B and reaches the upper surface of the operating portion 21. In this case, once the projection 21a is fixed in place by the locking portion 14 of the housing portion 1, the height of the upright portion 21C acts as a stopper, preventing it from protruding outwards from the opening 11 of the housing portion 1, while the sloping portion 21D facilitates insertion and removal from the locking portion 14.

[0045] Furthermore, as shown in Figure 6(c), the shape of the projection 21a can be configured to have an upright portion 21C that stands up at an acute angle θ1 at one end 21A of the operating portion 21, a slanted portion 21D that slopes toward the other end 21B until it reaches an acute angle θ2, and a second upright portion 21E that stands up at the other end 21B. In this case, once the projection 21a is fixed by the locking portion 14 of the housing portion 1, the upright portion 21C's slanted shape facilitates insertion and removal, and the height of the upright portion 21C acts as a stopper, preventing it from protruding forward from the opening 11 of the housing portion 1. Additionally, the slanted portion 21D facilitates insertion and removal from the locking portion 14, and the upright position of the second upright portion 21E provides a firm stopper in the depth direction when the locking portion 14 is fixed.

[0046] The insertion and removal operations of the communication unit 2 using the projection 21a of the communication unit 2 and the locking portion 14 of the housing 1 will be described below.

[0047] (Putting on) As shown in Figure 7(a), the projection 21a of the communication unit 2 is constantly subjected to an upward biasing force F as the communication unit 2 is inserted into the opening 11 of the housing 1. When the projection 21a enters the interior of the housing 1, it is pressed from the inner upper surface 12 of the housing 1 and sinks downward through the through hole 22b, transitioning to a flat state where it does not protrude from the through hole 22b, that is, a state where the projection 21a has no height.

[0048] While maintaining this state, the communication unit 2 can further penetrate the inside of the housing 1, using the inner upper surface 12 and inner lower surface 13 of the housing 1 as sliding surfaces C and D, respectively. As shown in Figure 7(b), on this sliding surface C, the projection of the protruding piece 21a of the communication unit 2 is constantly subjected to an upward biasing force F, but is also subjected to a downward pressing force A from the inner upper surface 12 of the housing 1, which is a greater force than the upward biasing force F, causing it to bend due to its elastic force. As a result, it sinks downward through the through hole 22b and maintains a flat state without protruding from the through hole 22b, allowing the communication unit 2 to slide and rub against the inside of the housing 1, moving from the front side to the back side.

[0049] When the projection 21a penetrates the depth of the interior of the housing 1 and reaches the locking portion 14 of the housing 1, as shown in Figure 7(c), the projection 21a separates from the sliding surface C and is no longer subjected to the downward pressing force A that it had been receiving from the sliding surface C. In this state, an upward biasing force F is always acting, and due to the elastic force of the operating portion 21, the upward biasing force F acts as an upward pressing force B on the projection of the projection 21a, causing the projection of the projection 21a to penetrate upward through the through hole 22b and protrude, restoring it to its original protruding state. The projection of the projection 21a, restored to its original state, fits into the hole shape of the locking portion 14 of the housing 1 and becomes locked, and the communication unit 2 is mounted inside the housing of the housing 1 and firmly fixed.

[0050] (Ejecting operation) To remove the communication unit 2 installed inside the housing 1, first, as shown in Figure 8(a), the operator applies a downward pressing force F1 to the handle 21b of the communication unit 2 installed inside the housing 1. This action causes the operating part 21 to bend due to its elastic force, as shown in Figure 5(b), and the protruding part of the projection 21a sinks downward through the through hole 22b, transitioning to a flat state where it no longer protrudes from the through hole 22b. In other words, this is the unlocking operation.

[0051] While pressing down on the handle 21b, the operator pulls the communication unit 2 forward from the opening 11 of the housing 1, allowing it to slide along the inside of the housing 1, using the inner upper surface 12 and inner lower surface 13 as sliding surfaces C and D, respectively, as shown in Figure 8(b). On sliding surface C, the projection 21a of the communication unit 2 is constantly subjected to an upward biasing force F, but is continuously subjected to a greater force than the upward biasing force F, namely the pressing force A from the inner upper surface 12 of the housing 1. As a result, the projection of the projection 21a sinks downward from the through hole 22b, maintaining a flat state where it does not protrude from the through hole 22b. Furthermore, on the inner lower surface 13, sliding surface D also enables the communication unit 2 to be stably removed from inside the housing 1 without wobbling.

[0052] When the communication unit 2 is removed from the front of the housing 1 and separated from the housing 1, it is physically separated from the sliding surface C, and as shown in Figure 8(c), it no longer receives the downward pressing force A that it previously received from the sliding surface C. On the other hand, the elastic force of the operating part 21 causes an upward biasing force F to act as an upward pressing force B on the projection of the protruding piece 21a, causing the projection of the protruding piece 21a to penetrate upward through the through hole 22b and protrude, restoring it to its original protruding state.

[0053] Thus, the operating section 21 is formed from a long elastic body, with one end 21A of this elastic body bent into a hook shape to form a handle 21b, and a projection 21a is formed in the middle of this elastic body, exposing the handle 21b on the front of the container, while the other end 21B of this elastic body is fixed to the back of the container. Therefore, with the communication unit 2 installed inside the housing, by pushing the handle 21b downward, the fixed other end 21B of this elastic body acts as a fulcrum. As a result, the projection 21a of the operating part 21 moves downward in conjunction with the point of action, separating the projection 21a of the operating part 21 from the locking part 14, thereby releasing the locking by the locking part 14. In this unlocked state, the communication unit 2 can be easily removed by pulling the handle 21b towards the front. Thus, the communication unit can be easily and securely attached and detached by a simple operation using the handle 21b.

[0054] Furthermore, since this elastic body is formed from a leaf spring or a plate containing a spring, the operating part 21 can be made of a single plate with a biasing force. Also, because the operating part 21 flexes due to its elastic force, the handle 21b becomes the point of force when pushed downward, and in conjunction with this, the other end 21B of the elastic body fixed to the back of the container becomes the fulcrum and supports it. In conjunction with this, the operating part 21 becomes the point of action and separates the elastic body from the locking part 14, and the locking by the locking part 14 is easily released, resulting in an unlocked state. This allows the communication unit to be attached and detached easily and securely using a simple pushing operation with the handle 21b, more efficiently. [Explanation of Symbols]
