[0026] Compared with the prior art, the technical solution of this utility model has the following advantages:

Therefore, it can improve the neatness of patch cord wiring and avoid tangling between different patch cords. Attached Figure Description

[0028] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of this application. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0029] Figure 1 This is a schematic diagram of the connection relationship of an optical fiber connection system according to an embodiment of the present invention;

[0030] Figure 2 This is a schematic diagram of the structure of a fiber optic distribution frame in one embodiment of the present invention. Detailed Implementation

[0031] As described in the background section, traditional fiber optic patching methods rely on manual operation, and there are many ports on the fiber optic distribution frame, resulting in different fiber optic patch cords being tangled and crossed.

[0032] Furthermore, in some application scenarios, the distance between different fiber optic distribution frames is relatively long, and the tangling and crossing of fiber optic patch cords will be more obvious.

[0033] To solve the above-mentioned technical problems, this utility model provides an optical fiber connection system, including a first optical fiber connection device and a second optical fiber connection device. Both the first and second optical fiber connection devices include at least one first type optical fiber distribution frame and at least one second type optical fiber distribution frame. For any one optical fiber connection device, by connecting the second type optical fiber distribution frame of the optical fiber connection device to the first type optical fiber distribution frame of the optical fiber connection device through a first type patch cord, and connecting it to the first type optical fiber distribution frame of another optical fiber connection device through a second type patch cord, a patch connection between any two optical fiber connection devices can be achieved.

[0034] In other words, this solution uses the second type of fiber optic distribution frame as a "bridge" to connect most of the patch cords, reducing the length of the first and second type patch cords and simplifying the patching process. This improves the neatness of the patch cord wiring and avoids tangling between different patch cords.

[0035] To enable those skilled in the art to better understand and implement this utility model, the following detailed description of the specific scheme, principle, advantages, and effects of this utility model is provided with reference to the accompanying drawings and specific embodiments.

[0036] See Figure 1 The diagram shown is a connection relationship diagram of an optical fiber connection system according to an embodiment of the present invention. Figure 1As shown, the fiber optic connection system may include a first fiber optic connection device CN1 and a second fiber optic connection device CN2.

[0037] It should be noted that the "first" and "second" in this scheme are not used to limit the number of fiber optic connection devices, but rather to indicate fiber optic connection devices connected by patch cords, and should not be construed as limitations on this utility model.

[0038] For example, the fiber optic connection system may also include a third fiber optic connection device, which is further connected to a second type of fiber optic patch panel in the first fiber optic connection device and / or the second fiber optic connection device via a third type of patch cord.

[0039] This allows a local area network to be formed by connecting multiple fiber optic connection devices.

[0040] In this embodiment, both the first optical fiber connection device CN1 and the second optical fiber connection device CN2 include: at least one first type optical fiber distribution frame and at least one second type optical fiber distribution frame.

[0041] In some embodiments, such as Figure 1 As shown, the first fiber optic connection device CN1 may include three first-type fiber optic distribution frames (e.g., Figure 1 The diagram illustrates a first type of fiber optic distribution frame (ODF11, ODF12, and ODF13) and a second type of fiber optic distribution frame (e.g., Figure 1 (Illustrated second type of fiber optic distribution frame ODF14).

[0042] Accordingly, the second fiber optic connection device CN2 may include three first-type fiber optic distribution frames (e.g., Figure 1 The diagram illustrates a first type of fiber optic distribution frame (ODF21, ODF22, and ODF23) and a second type of fiber optic distribution frame (e.g., Figure 1 (Illustrated second type of fiber optic distribution frame ODF24).

[0043] It should be noted that: First, this solution is illustrated using a first optical fiber connection device CN1 and a second optical fiber connection device CN2 as an example. In some other embodiments, more than three optical fiber connection devices may be included. Second, the terms "first type optical fiber distribution frame" and "second type optical fiber distribution frame" in this solution are merely illustrative examples, used to represent two different types of optical fiber distribution frames. In reality, the structure and purpose of each optical fiber distribution frame can be the same. This solution simplifies patch cord operations by dividing the optical fiber distribution frames and should not be construed as a limitation on this utility model. Third, the number of "first type optical fiber distribution frames" and "second type optical fiber distribution frames" is also illustrative, used to indicate that any optical fiber connection device can be composed of multiple optical fiber distribution frames. In some other embodiments, one first type optical fiber distribution frame and one second type optical fiber distribution frame may be included, and this should not be construed as a limitation on this utility model.

[0044] In this embodiment, for any one of the first optical fiber connection devices CN1 and CN2, the second type of optical fiber distribution frame in the optical fiber connection device is connected to the first type of optical fiber distribution frame in the optical fiber connection device through a first type of patch cord, and is also connected to the first type of optical fiber distribution frame of the other optical fiber connection device through a second type of patch cord.

[0045] More specifically, each type II fiber optic patch panel includes a first pre-connection area and a second pre-connection area, each of which includes at least one pre-connection port. Correspondingly, each type I fiber optic patch panel includes a third pre-connection area and a fourth pre-connection area, each of which includes at least one pre-connection port.

[0046] Therefore, the pre-connection port of the first pre-connection area in the second type of fiber optic distribution frame is connected to the pre-connection port of the third pre-connection area in the first type of fiber optic distribution frame of the same fiber optic connection device via a first type of patch cord.

[0047] As an optional example, see Figure 1 The pre-connection port on the first pre-connection area (not shown in the figure) of the second type fiber distribution frame ODF14 in the first fiber connection device CN1 is connected to the pre-connection port on the third pre-connection area of ​​the first type fiber distribution frame ODF11 in the first fiber connection device CN1 via the first type patch cord L11; it is connected to the pre-connection port on the third pre-connection area of ​​the first type fiber distribution frame ODF12 via the first type patch cord L12; and it is connected to the pre-connection port on the third pre-connection area of ​​the first type fiber distribution frame ODF13 via the first type patch cord L13.

[0048] Thus, by using the first type of patch cords L11 to L13, the patching between the fiber optic distribution frames inside the first fiber optic connection device CN1 is achieved.

[0049] Accordingly, the pre-connection port of the second pre-connection area in the second type of fiber optic patch panel of the first fiber optic connection device is connected to the pre-connection port of the fourth pre-connection area in the first type of fiber optic patch panel of the second fiber optic connection device via a second type of patch cord.

[0050] See next Figure 1 The pre-connection port of the second pre-connection area (not shown in the figure) in the second type of fiber distribution frame ODF14 in the first fiber connection device CN1 is also connected to the pre-connection port of the fourth pre-connection area (not shown in the figure) in the first type of fiber distribution frame ODF21 in the second fiber connection device CN2 via the second type of patch cord L24, connected to the pre-connection port of the fourth pre-connection area in the first type of fiber distribution frame ODF22 via the second type of patch cord L25, and connected to the pre-connection port of the fourth pre-connection area in the first type of fiber distribution frame ODF23 via the second type of patch cord L26.

[0051] Thus, by using the second type of patch cords L24 to L26, a patching connection between the first fiber optic connection device CN1 and the second fiber optic connection device CN2 was achieved, i.e., a patching connection across devices.

[0052] As an optional example, see Figure 1 The pre-connection port of the first pre-connection area in the second type of fiber optic distribution frame ODF24 in the second fiber optic connection device CN2 is connected to the pre-connection port of the third pre-connection area in the first type of fiber optic distribution frame ODF21 in the second fiber optic connection device CN2 via the first type of patch cord L14, to the pre-connection port of the third pre-connection area in the first type of fiber optic distribution frame ODF22 via the first type of patch cord L15, and to the pre-connection port of the third pre-connection area in the first type of fiber optic distribution frame ODF23 via the first type of patch cord L16.

[0053] Thus, by using the first type of patch cords L14 to L16, the patching between the fiber optic distribution frames inside the second fiber optic connection device CN2 was achieved.

[0054] See next Figure 1 The pre-connection port of the second pre-connection area in the second type of fiber optic distribution frame ODF24 in the second fiber optic connection device CN2 is also connected to the pre-connection port of the fourth pre-connection area in the first type of fiber optic distribution frame ODF11 in the first fiber optic connection device CN1 via the second type of patch cord L21, to the pre-connection port of the fourth pre-connection area in the first type of fiber optic distribution frame ODF12 via the second type of patch cord L22, and to the pre-connection port of the fourth pre-connection area in the first type of fiber optic distribution frame ODF13 via the second type of patch cord L23.

[0055] Thus, by using the second type of patch cords L21 to L23, a jumper connection between the first fiber optic connection device CN1 and the second fiber optic connection device CN2 was achieved, i.e., a jumper connection across devices.

[0056] In this embodiment, see Figure 1 In the case where both the first fiber optic connection device and the second fiber optic connection device include three first-type fiber optic distribution frames and one second-type fiber optic distribution frame, the first pre-connection area is divided into three sub-areas. Each sub-area is connected to a third pre-connection area of ​​a first-type fiber optic distribution frame of the same fiber optic connection device, and the number of each sub-area corresponds to the number of ports in the corresponding third pre-connection area.

[0057] In other words, a first pre-connected area of ​​a second type fiber optic distribution frame is simultaneously connected to a third pre-connected area of ​​three first type fiber optic distribution frames.

[0058] For example, see Figure 1 The first pre-connection area of ​​the second fiber optic connection device ODF14 is simultaneously connected to the third pre-connection areas of the first fiber optic connection devices ODF11, ODF12 and ODF13.

[0059] The first pre-connection area of ​​the second fiber optic connection device ODF24 is simultaneously connected to the third pre-connection areas of the first fiber optic connection devices ODF21, ODF22 and ODF23.

[0060] The second pre-connection area is divided into three sub-areas. Each sub-area is connected to a fourth pre-connection area of ​​a first-type fiber optic patch panel of another fiber optic connection device, and the number of each sub-area corresponds to the number of ports in the corresponding fourth pre-connection area.

[0061] In other words, a second pre-connected area of ​​a Type 2 fiber optic distribution frame is simultaneously connected to a third pre-connected area of ​​three Type 4 fiber optic distribution frames.

[0062] For example, see Figure 1 The first pre-connection area of ​​the second fiber optic connection device ODF14 is simultaneously connected to the third pre-connection areas of the first fiber optic connection devices ODF11, ODF12 and ODF13.

[0063] The first pre-connection area of ​​the second fiber optic connection device ODF24 is simultaneously connected to the fourth pre-connection areas of the first fiber optic connection devices ODF21, ODF22 and ODF23.

[0064] In this embodiment, the fiber optic patch panel selected as the second type of fiber optic patch panel satisfies the following condition: the total distance between this fiber optic patch panel and other fiber optic patch panels is minimized. This reduces the length of the patch cords used and achieves centralized connection of the patch cords, thereby further improving the neatness of the patch cord wiring and avoiding tangling between different patch cords.

[0065] Furthermore, during the actual patching process, the inventors discovered that if the first type of fiber optic patch panel ODF11 is directly connected to the first type of fiber optic patch panel ODF21, firstly, the distance between the two is too long, increasing the probability of different patch cords getting tangled, and if the distance is further increased, it may be impossible to find a patch cord of suitable length; secondly, under normal circumstances, the second fiber optic connection device CN2 and the first fiber optic connection device CN1 are placed in different computer rooms, and longer patch cords are not conducive to cabling.

[0066] Therefore, this solution uses the second type of fiber optic patch panel that is relatively close to each other as a "bridge", which can improve the neatness of patch cord wiring and avoid tangling between different patch cords.

[0067] It should be noted that, Figure 1 Only a portion of the patch cords are shown, and do not represent the actual wiring. They are only used to illustrate that different fiber optic patch panels can be connected via patch cords.

[0068] In this embodiment, the first type of fiber optic patch panel and the second type of fiber optic patch panel can adopt the same architecture.

[0069] In other words, the physical parameters (such as the number of ports, specifications, etc.) of the first type and the second type of fiber optic distribution frame are the same. This solution uses different identifiers only to distinguish the fiber optic distribution frame that serves as a "bridge".

[0070] For example, each of the fiber optic patch panels has a preset number of ports, including pre-connected ports.

[0071] Accordingly, both the first type of fiber optic distribution frame CN1 and the second type of fiber optic distribution frame CN2 include: multiple connection areas, with pre-connected ports distributed in the multiple connection areas.

[0072] In this embodiment, by performing a partitioning operation, the cabling can be further optimized so that each patch cord is distributed on the fiber optic patch panel; and by distributing the pre-connected ports in corresponding connection areas, wiring is facilitated.

[0073] Therefore, point-to-point (i.e., any to any) connections between any two ports can be achieved according to actual needs.

[0074] For ease of understanding and explanation, the ODFX fiber optic distribution frame is used as an example for illustration. The ODFX fiber optic distribution frame can be at least one of a first type of fiber optic distribution frame and a second type of fiber optic distribution frame. In this embodiment, the ODFX fiber optic distribution frame is used as an example of a first type of fiber optic distribution frame for illustration.

[0075] Combination Figure 1 See Figure 2 The diagram shown is a structural schematic of a fiber optic distribution frame according to one embodiment of the present invention. Figure 2 As shown, the ODFX fiber optic patch panel includes four connection areas.

[0076] Furthermore, these four areas are the first external connection area I, the second external connection area IV, the first optical cable access area II, and the second optical cable access area III.

[0077] In this embodiment, the first optical cable access area II and the second optical cable access area III are located between the first external connection area I and the second external connection area IV, and the order can be as follows: first external connection area I, first optical cable access area II, second optical cable access area III and second external connection area IV.

[0078] In this embodiment, for different fiber optic distribution frames, when divided into 4 areas, the positions of the first pre-connection area and the second pre-connection area, the second pre-connection area and the third pre-connection area can be different.

[0079] For example, see Figure 1 and Figure 2 For the first fiber optic connection device, the first external connection area I in the second type of fiber optic distribution frame serves as the first pre-connection area, the first optical cable access area II serves as the second pre-connection area, and the first external connection area I in the first type of fiber optic distribution frame serves as the third pre-connection area and the second external connection area IV serves as the fourth pre-connection area; while for the second fiber optic connection device, the second optical cable access area III in the second type of fiber optic distribution frame serves as the first pre-connection area, the second external connection area IV serves as the second pre-connection area, and the first external connection area I in the first type of fiber optic distribution frame serves as the fourth pre-connection area and the second external connection area IV serves as the third pre-connection area.

[0080] It should be pointed out that, firstly, Figure 2 The number of regions and their distribution are merely illustrative examples used to illustrate the functions of different regions of the fiber optic distribution frame and should not be construed as limiting the present invention. Secondly, the location of the pre-connected regions is also merely illustrative, used to illustrate the relative connection relationship between the second type of fiber optic distribution frame and the first type of fiber optic distribution frame.

[0081] In this embodiment, the number of ports in the first external connection area I is 96, the number of ports in the second external connection area IV is 96, the number of ports in the first optical cable access area II is 256, and the number of ports in the second optical cable access area III is 128.

[0082] In other words, any fiber optic patch panel has 576 ports.

[0083] It should be noted that the number of ports in each connection area can be adjusted in real time, as long as the number of ports on the fiber optic distribution frame remains consistent. For example, in some embodiments, the number of ports in the first external connection area is 96, the number of ports in the second external connection area is 48, the number of ports in the first optical cable access area is 288, and the number of ports in the second optical cable access area is 144.

[0084] In this embodiment, when the connection area includes a first external connection area, a second external connection area, a first optical cable access area, and a second optical cable access area, the specific connection relationship between the first optical fiber connection device CN1 and the second optical fiber connection device CN2, which have a connection relationship, can be as follows:

[0085] The first external connection area and the first optical cable access area of ​​one of the two type II fiber optic distribution frames are connected to all type I fiber optic distribution frames; the second external connection area and the second optical cable access area of ​​the other type II fiber optic distribution frame are connected to all type I fiber optic distribution frames.

[0086] In other words, the areas in the two connected Type II fiber optic distribution frames include these four areas, so that any one area of ​​any fiber optic distribution frame can be connected to the other three areas through the corresponding patch cord, thereby making use of the ports of other fiber optic distribution frames.

[0087] In this embodiment, see Figure 1 The pre-connection port on the first external connection area I of the second type fiber distribution frame ODF14 in the first fiber connection device CN1 is connected to the pre-connection port on the first external connection area I of the first type fiber distribution frame in the first fiber connection device CN1 through the first type of patch cord.

[0088] For example, the pre-connected port on the first external connection area I of the second type fiber optic distribution frame ODF14 is connected to the pre-connected port on the first external connection area I of the first type fiber optic distribution frame ODF11 via the first type jumper L11; it is connected to the pre-connected port on the first external connection area I of the first type fiber optic distribution frame ODF12 via the first type jumper L12; and it is connected to the pre-connected port on the first external connection area I of the first type fiber optic distribution frame ODF13 via the first type jumper L13.

[0089] The pre-connected port on the first optical cable access area II of the second type optical fiber distribution frame ODF14 in the first optical fiber connection device CN1 is connected to the pre-connected port on the first external connection area I of the first type optical fiber distribution frame in the second optical fiber connection device CN2 via the second type of patch cord.

[0090] For example, the pre-connected port on the first optical cable access area II of the second type of fiber distribution frame ODF14 is connected to the pre-connected port on the first external connection area I of the first type of fiber distribution frame ODF21 in the second fiber optic equipment ODF21 via the second type of patch cord L24; it is connected to the pre-connected port on the first external connection area I of the first type of fiber distribution frame ODF22 via the second type of patch cord L25; and it is connected to the pre-connected port on the first external connection area I of the first type of fiber distribution frame ODF23 via the second type of patch cord L26.

[0091] Correspondingly, the pre-connected port on the second external connection area IV of the second type of fiber optic distribution frame ODF24 in the second fiber optic connection device CN2 is connected to the pre-connected port on the second external connection area IV of the first type of fiber optic distribution frame in the first fiber optic connection device CN1 through the second type of patch cord.

[0092] For example, the pre-connected port on the second external connection area IV of the second type of fiber optic distribution frame ODF24 is connected to the pre-connected port on the second external connection area IV of the first type of fiber optic distribution frame ODF11 via the second type of patch cord L21; it is connected to the pre-connected port on the second external connection area IV of the first type of fiber optic distribution frame ODF12 via the second type of patch cord L22; and it is connected to the pre-connected port on the second external connection area IV of the first type of fiber optic distribution frame ODF13 via the second type of patch cord L23.

[0093] The pre-connected port on the second optical cable access area III of the second type of optical fiber distribution frame ODF24 in the second optical fiber connection device CN2 is connected to the pre-connected port on the second external connection area IV of the first type of optical fiber distribution frame in the second optical fiber connection device CN2 through the first type of patch cord.

[0094] For example, the pre-connected port on the second optical cable access area III of the second type of fiber distribution frame ODF24 is connected to the pre-connected port on the second external connection area IV of the first type of fiber distribution frame in the second fiber connection device CN2 via the first type of patch cord L14; it is connected to the pre-connected port on the second external connection area IV of the first type of fiber distribution frame ODF22 via the first type of patch cord L15; and it is connected to the pre-connected port on the second external connection area IV of the first type of fiber distribution frame ODF23 via the first type of patch cord L16.

[0095] See next Figure 1The second type of fiber optic distribution frame ODF14 and the second type of fiber optic distribution frame ODF24 act as a "bridge". They are not connected by patch cords, but are connected to each other through their respective first type of fiber optic distribution frames.

[0096] In this embodiment, each fiber optic patch panel also includes a patch port, and the patch ports can be distributed in various connection areas or in one of the areas. This utility model does not limit this.

[0097] Accordingly, for any first type fiber distribution frame and / or at least one second type fiber distribution frame, different patch ports in the same first type fiber distribution frame are connected by a fourth type patch cord, or different patch ports in the same second type fiber distribution frame are connected, and one of the patch ports connected is a port that is pre-connected to the pre-connected port.

[0098] For example, see Figure 2 This illustrates the connection of the jumper ports on the first optical access area II and the second optical access area III via a fourth type jumper L3X, with one of the jumper ports already pre-connected to a pre-connected port.

[0099] More specifically, the jumper ports include first-type jumper ports (e.g., Figure 2 Port A (as shown in the diagram) and second-class jumper ports (e.g., Figure 2 Port B is shown in the diagram. The second type of patch port is a port that is pre-connected to the pre-connected port. Furthermore, since the patch port being connected is pre-connected to the pre-connected port, port patching between different fiber optic distribution frames, i.e., any to any port connection, is achieved through the first type of patch cord and the second type of patch cord L3X.

[0100] In some embodiments, for the first type of fiber optic distribution frame, the pre-connection port can be set in the first external connection area I and the second external connection area IV. For the second type of fiber optic distribution frame, the pre-connection port can be set in the first optical cable access area II and the first external connection area I, or it can be set in the second optical cable access area III and the second external connection area IV. Thus, the connection between different distribution frames can be realized through the first type of patch cord and / or the second optical cable access area II.

[0101] Correspondingly, the patch ports can be set in the first optical cable access area II and the second optical cable access area III within the four areas, thereby connecting the patch ports in these two areas via a third type of patch cord.

[0102] More specifically, in one embodiment, when the jumper port includes a first type of jumper port and a second type of jumper port, such as Figure 2As shown, the first type of jumper port A can be set in the area indicated by the dashed box G1 in the first optical cable access area II, and the second type of jumper port B can be set in the area indicated by the dashed box G2 in the second optical cable access area III.

[0103] In one alternative embodiment, the number of patch ports (also known as spare ports) is one-third of the total number of ports. In other words, patch ports and pre-connected ports constitute a connection channel on a fiber optic patch panel.

[0104] It should also be noted that, firstly, the second type of fiber optic distribution frame can have more patch ports to facilitate connections between one second type fiber optic distribution frame and three first type fiber optic distribution frames; secondly... Figure 2 The examples shown, illustrating the connection of ports in different areas via the fourth type of jumper, are merely illustrative and should not be construed as limiting the scope of this invention. Third, when the first, second, and fourth types of jumpers are included simultaneously, each jumper occupies only one port at one end. Fourth, the distribution of jumper ports and pre-connected ports in the above examples is merely illustrative and is used to indicate their location. In actual operation, jumper ports and pre-connected ports can be distributed in any of these areas.

[0105] In this embodiment, each connection area includes an interface panel, and a preset number of ports (including pre-connected ports and / or jumper ports) are set on the interface panel, and the interface panel also has an identification code indicating the port.

[0106] In other words, the port is located on the interface panel, and the interface panel has an identification code indicating the location of the port. Therefore, by detecting the identification code, it can be determined whether the port is occupied.

[0107] As an example, see Figure 2 The ODFX fiber optic patch panel has an interface panel (MB), on which the ports for each area are located.

[0108] In this embodiment, in order to facilitate the fixing and installation of the interface panel and improve the stability of the interface panel during operation, the fiber optic connection device may further include: a mounting frame, in which the first type of fiber optic patch panel and / or the second type of fiber optic patch panel are placed.

[0109] In other words, the stability of the interface panel can be improved by configuring the installation framework.

[0110] It should be noted that in this embodiment, one fiber optic patch panel corresponds to one interface panel.

[0111] Furthermore, the fiber optic connection device may also include a movable bracket disposed inside the mounting frame, and a housing disposed outside the mounting frame, wherein the housing divides the mounting frame into a jumper cabinet and a base cabinet, and a power supply is disposed inside the base cabinet.

[0112] By installing a casing, dust or other particles can be prevented from dripping onto the ports, improving the cleanliness of the working environment.

[0113] Correspondingly, both the interface panel and the movable bracket are located inside the fiber jumper cabinet, and the interface panel can be detachably installed on the mounting frame.

[0114] In this embodiment, the outer casing is provided with a cabinet door, which is used to perform maintenance operations on the fiber optic distribution frame by opening and closing the cabinet door.

[0115] Correspondingly, the fiber optic connection device may also include an abutment portion disposed at the bottom of the housing and in contact with the cabinet door, a push rod abutting the cabinet door, and an elastic element connected at one end to the push rod and at the other end to the bottom of the housing. Thus, when the cabinet door is opened, the elastic element causes the push rod to move, thereby pushing the cabinet door open and reducing the difficulty of opening it; furthermore, when the cabinet door is closed, the abutment of the elastic element makes the closing process of the cabinet door relatively slow, thereby reducing the impact of opening and closing the cabinet door on the fiber optic distribution frame.

[0116] In this embodiment, the fiber optic connection device may further include: a clamping device electrically connected to the power supply and installed on the jumper cabinet, the clamping device being movable on a movable bracket to realize the plugging operation of the first type of jumper and / or the second type of jumper.

[0117] It is understood that the above description provides multiple embodiment solutions, and the optional methods described in each embodiment solution can be combined and cross-referenced with each other without conflict, thereby extending to a variety of possible embodiment solutions, all of which can be considered as the embodiment solutions disclosed in this disclosure.

[0118] Although the embodiments disclosed in this specification are as described above, this utility model is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
