Description

Technical Field

[0001] The utility model relates to the field of wire trough connection accessories, in particular to a wire trough connection accessory. Background Art

[0002] Cabling is a technology that combines multiple wires to form modular, highly flexible information transmission channels within a building or between buildings. It connects various voice and data communication devices, switching equipment, and other information management systems to each other and connects these devices to external communication networks, thereby supporting the transmission of voice applications, data, and video.

[0003] The cabling system is the foundational infrastructure for the development of digital information systems in intelligent buildings. It is a structured cabling system that unifies the planning and design of all voice, data, and other systems. It provides the building's information-based and intelligent material medium and supports future integrated applications such as voice, data, graphics, and multimedia. Therefore, ensuring the security of the cabling system is particularly important during construction and routine maintenance.

[0004] When installing wire troughs, construction workers often encounter wires crossing each other in different directions. When dealing with wires crossing in different directions, the traditional solution is to use wire trough cross connectors or bridge bend accessories to connect them.

[0005] However, the traditional cross-connect fittings have a simple internal structure, which causes wires in different directions to come into contact and cross-extrude with each other when connected to the cable duct, which can easily cause line overload, wire temperature rise, and lead to short circuit and fire.

[0006] At the same time, another traditional bridge bend accessory connection will have the problem of unsealed connection with the cable trough and poor structural strength. Long-term use will not only make it easy for mosquitoes to enter and damage the wires, which may cause short circuits and fires, but also the poor internal structure strength will make it easy to be squeezed or damaged by collision, causing the risk of leakage. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wire trough connection accessory, which can avoid cross-extrusion of wires inside the accessory and reduce the risk of leakage caused by pressure resistance or collision damage.

[0008] An embodiment of the present invention provides a wire trough fitting, comprising a base, the base being provided with a cavity capable of accommodating wires, and characterized in that the base further comprises at least one partition layer;

[0009] The separation layer is arranged in the cavity of the base, and divides the cavity into at least two independent wiring spaces.

[0010] Compared with the existing technology, by setting up a separation layer, the internal wiring space is divided into several independent and unconnected wiring spaces, which can avoid the problem of line overload caused by cross-extrusion of wires, the increase of wire temperature and the resulting short circuit and fire caused by wires, thereby improving the safety of circuit construction.

[0011] Furthermore, the cavity is a cross-shaped cavity, and the one partition layer is arranged in the cavity of the base to separate the cavity into a first wiring space and a second wiring space that are independent of each other.

[0012] Furthermore, the cavity is a petal-shaped cavity, comprising two partition layers, and the two partition layers are arranged in the cavity of the base to divide the cavity into three independent wiring spaces.

[0013] Furthermore, the cavity is a 'M'-shaped cavity, and four partition layers are arranged in the cavity of the base to divide the cavity into three independent wiring spaces.

[0014] Compared with the prior art, the wire trough connector provided by the present invention is adaptively provided with different numbers of separation layers according to the different shapes of the cavities formed by the base, which can greatly improve the practicality of the present invention.

[0015] Furthermore, the separation layer is provided at the intersection area of ​​the wiring space.

[0016] Furthermore, the separation layer is an arched structure, and the separation layer (3) separates the cavity (7) into mutually independent wiring spaces.

[0017] Compared to the prior art, the present invention provides an arched partition layer at the cross-section of the base of the wire trough fitting, which can divide the internal wiring space. For example, it can be divided into two layers, the first wiring space and the second wiring space, which are not connected to each other. As a result, in actual wiring construction scenarios, crossing wires in different directions do not contact or interfere with each other, avoiding the problem of line overload caused by cross-extrusion of wires, the increase in wire temperature, and the resulting short circuit fire, thereby improving the safety of circuit construction.

[0018] Preferably, guide reinforcement bones are provided on both sides of the arch edge of the separation layer.

[0019] Compared with the prior art, the guide reinforcement frames provided on both sides of the partition layer of the wire trough connection accessories provided by the present invention are not only conducive to the orderly wiring of wires, but also can enhance the internal structural strength and reduce the risk of leakage caused by pressure resistance or collision damage.

[0020] Furthermore, the top of the base is fixedly connected to an upper cover.

[0021] Compared with the prior art, the wire trough fittings provided by the present invention form a closed internal wiring space by providing an upper cover and interlocking the upper cover with the base, which can protect the wires from being invaded by small animals such as mosquitoes outside, and prevent small animals such as mosquitoes from entering the wire trough to damage the wires and cause a short circuit and fire.

[0022] Preferably, the upper cover is fixedly connected to the top of the base through a snap-fit ​​structure;

[0023] A plurality of male buckles are provided on the side wall of the base, and a plurality of female buckles are correspondingly provided on the side wall of the upper cover. The upper cover is fixed to the base by engaging the plurality of female buckles with the plurality of male buckles of the base.

[0024] Compared with the prior art, the wire trough connection accessories provided by the utility model can make the installation of accessories more flexible through the snap-on connection setting, so that the cross-connection accessories can be repeatedly assembled and disassembled in actual work, and are also convenient for construction personnel to install wiring and conduct subsequent maintenance.

[0025] Preferably, the side walls of the upper cover and the base are both provided with a plurality of screw holes or through holes, and screws or rivets pass through the screw holes or through holes to fix the upper cover to the base.

[0026] Compared with the prior art, the wire trough fitting provided by the utility model rivets the upper cover and the base to each other, which can make the fit between the two more secure, and further improve the sealing and safety of the internal wiring space.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) Separation and protection of wires: By setting up a separation layer, the wiring space on the base is formed into two layers of space, namely longitudinal and transverse, which are used to separate the cross wires in different directions in the interior, thereby preventing the wires from being short-circuited and causing fire due to overload and temperature rise caused by cross-extrusion of wires;

[0029] (2) Strong structural compressive resistance: The internal structural design of the guide frame and the separation layer frame realizes the separation of the cross wires in different directions inside, which is not only conducive to orderly wiring, but also enables construction workers to quickly install and connect, and can strengthen the internal structural strength while reducing the risk of leakage caused by pressure resistance or collision damage.

[0034] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting this patent;

[0035] It is understandable to those skilled in the art that some well-known structures and descriptions thereof may be omitted in the drawings.

[0036] The technical solution of the present utility model is further described below with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1 , is a structural diagram of a wire trough connection accessory provided by an embodiment of the present invention, comprising a base 1, the base 1 is provided with a cavity 7 capable of accommodating wires, and further comprising at least one partition layer 3;

[0038] The separation layer 3 is disposed in the cavity 7 of the base 1 , and divides the cavity 7 into at least two independent wiring spaces.

[0039] Compared with the existing technology, the wire trough fittings provided by the present invention form a separation layer to form several layers of space in different directions in the wiring space on the base, which is used to separate the crossing wires in different directions inside, and can avoid the line overload and wire temperature increase caused by the cross-extrusion of wires, which may lead to short circuit and fire.

[0040] Furthermore, the cavity 7 is a cross-shaped cavity, and the partition layer 3 is disposed in the cavity 7 of the base 1 to separate the cavity 7 into a first wiring space 8 and a second wiring space 9 that are independent of each other.

[0041] In a preferred embodiment, referring to Figure 2 , is a schematic diagram of a usage scenario when a wire trough connector provided by an embodiment of the present invention is used in combination with a wire trough. Figure 2 As can be seen, during wiring, the horizontal and vertical wires are distributed in the first and second wiring spaces 8 and 9, respectively, which are not interconnected. Therefore, the horizontal and vertical wires do not touch each other, preventing cross-extrusion of wires, which could cause line overloads, heat rise, and potentially short circuits and fires, thereby improving circuit construction safety.

[0042] Furthermore, the cavity 7 is a petal-shaped cavity, including two partition layers 3. The two partition layers 3 are arranged in the cavity 7 of the base 1 to divide the cavity 7 into three independent wiring spaces.

[0043] Furthermore, the cavity 7 is a 'M'-shaped cavity, and four partition layers 3 are arranged in the cavity 7 of the base 1 to divide the cavity 7 into three independent wiring spaces.

[0044] In a preferred embodiment, depending on the shape of the cavity 7 formed by the base 1, construction personnel can adaptably set different numbers of separation layers 3 on the base 1 to meet the requirements of separating wires in different directions. This flexible arrangement can greatly improve the practicality of the wire trough connector provided by the utility model.

[0045] Furthermore, the separation layer 3 is provided on the base 1 and specifically comprises:

[0046] The separation layer 3 is provided at the intersection region of the wiring spaces.

[0047] Furthermore, the separation layer 3 is an arched structure, and the separation layer 3 separates the cavity 7 into independent wiring spaces.

[0048] In a preferred embodiment, Figure 2 It can be seen that the separation layer 3 is arranged in the middle part of the base 1, that is, the cross-intersection area of ​​the base 1.

[0049] The separation layer 3 is an arched structure. When the cross connector provided by the present invention is used in combination with a wire duct, the separation layer 3 is arranged in a cross-intersection area on the base 1, thereby being able to separate the horizontal wires from the vertical wires.

[0050] Preferably, guide reinforcement frames 6 are provided on both sides of the arch edge of the separation layer 3 .

[0051] In a preferred embodiment, referring to Figure 1 The arched sides of the separation layer 3 are both provided with guide reinforcement frames 6. This arrangement is not only conducive to wiring the wires but also can strengthen the internal structure strength, and can also reduce the risk of leakage caused by pressure resistance or collision damage.

[0052] Furthermore, the top of the base 1 is also fixedly connected to the upper cover 2.

[0053] In a preferred embodiment, referring to Figure 1The wire trough fitting provided by the utility model is provided with an upper cover 2, and the upper cover 2 and the base 1 are interlocked to form a closed internal wiring space, which can protect the wires from being invaded by small animals such as mosquitoes outside, and prevent small animals such as mosquitoes from entering the wire trough to damage the wires and cause a short circuit and fire.

[0054] Furthermore, the upper cover 2 is fixedly connected to the top of the base 1 through a snap-fit ​​structure;

[0055] A plurality of male buckles 4 are provided on the side wall of the base 1 , and a plurality of female buckles 5 are correspondingly provided on the side wall of the upper cover 2 . The upper cover 2 is fixed to the base 1 by engaging the plurality of female buckles 5 with the plurality of male buckles 4 of the base 1 .

[0056] In a preferred embodiment, referring to Figure 1 To improve the sealing of the cross joint and prevent small animals such as mosquitoes from entering the fitting and damaging the wires, causing a short circuit and fire, this preferred embodiment has male buckles 4 and female buckles 5 on the side walls of the base 1 and the upper cover 2, respectively. These buckles are used to secure the upper cover 2 and the base 1 to each other through a snap-fit ​​connection after the upper cover 2 and the base 1 are engaged, forming a sealed space (i.e., the internal wiring space). The snap-fit ​​connection allows for more flexible installation of the fitting, allowing the cross joint to be repeatedly assembled and disassembled in actual operation, and also facilitates wiring installation and subsequent maintenance by construction personnel.

[0057] In actual use, the positions of the male buckle 4 and the female buckle 5 are not fixed, and the male buckle 4 can also be set on the side wall of the upper cover 2, and in this case the female buckle 5 is set on the side wall of the base 1.

[0058] In another embodiment provided by the present invention, a plurality of screw holes or through holes are provided on the side walls of the upper cover 2 and the base 1, and screws or rivets pass through the screw holes or through holes to fix the upper cover 2 to the base 1.

[0059] As another preferred embodiment, a plurality of through-holes are provided on the sidewalls of the base 1 and the upper cover 2, and the base 1 and the upper cover 2 are riveted together. This cross-connect assembly also forms a closed internal wiring space, protecting the circuit from damage by small animals such as mosquitoes. Riveting is safer and more reliable than snap-on connections, but is less flexible for repeated assembly and disassembly. Construction personnel can choose the appropriate method based on actual conditions.

[0060] Furthermore, the cross-intersection area of ​​the upper cover 2 is bulged upward, and the height of the bulge is not less than a preset height threshold.

[0061] In a preferred embodiment, referring to Figure 3, is a cross-sectional view of a usage scenario when a wire duct connection accessory provided by an embodiment of the present invention is used in combination with a wire duct. Figure 3 As can be seen, to accommodate the structure of the separator layer 3, the cross-section of the upper cover 2 is raised upward. Furthermore, to provide sufficient wiring space for the wires, the height of the raised section should not be less than the wire diameter. Similarly, the arch height of the separator layer 3 should not be less than the wire diameter.

[0062] Furthermore, the base 1 , the upper cover 2 and the separation layer 3 are all formed by injection molding.

[0063] In summary, the present invention provides a novel wire trough connector. The cross connector structure is formed by an injection mold and consists of a base 1 and an upper cover 2.

[0064] The base 1 and the upper cover 2 are connected by a snap-on connection, which not only facilitates wiring installation and subsequent circuit maintenance, but also forms a sealed space after being connected to the wire trough, protecting the wires from small animals such as mosquitoes outside.

[0065] In addition, the internal wiring space formed by the mutual interlocking of the base 1 and the upper cover 2 is formed by cleverly designing the frame position, so that the internal wiring space forms two layers of space, namely the first wiring space and the second wiring space, thereby avoiding the short circuit and fire caused by the line overload and the increase of the wire temperature due to the cross-extrusion of the wires.

[0066] Finally, the internal structural frame layering of the wire trough cross-connection accessories provided by the present invention can not only be used to separate the crossing wires in different directions inside to avoid cross-extrusion of the wires, but also strengthen the internal structural strength and reduce the risk of leakage caused by pressure resistance or collision damage.

[0067] In summary, the wire duct fitting provided by the present invention has the following advantages over the prior art:

[0068] Advantage 1: Large space and easy installation and maintenance: The cross connector provided by this utility model is connected by a base and a top cover with a snap-on connection. The internal design has a guide bone position, which is conducive to orderly wiring, can be quickly installed and connected, and can be repeatedly assembled and disassembled. Compared with traditional cross connectors and bridge bends, the cross connector provided by this utility model not only has sufficient internal wiring space, but also can greatly improve the efficiency of engineering wiring installation and construction and the convenience of subsequent wire maintenance.

[0069] Advantage 2: Separation and protection of wires: The internal structural design of the base and the upper cover forms an internal space consisting of two layers of space, namely longitudinal and transverse, which are used to separate the crossed wires in different directions in the interior, and can avoid the overload of the line and the increase of the temperature of the wires caused by the cross-extrusion of the wires, which may lead to short circuit and fire.

[0070] Advantage 3: Strong Sealing: Compared to traditional cross-connect fittings, which have open bottoms and poor sealing, this cross-connect fitting easily allows small animals such as mosquitoes to enter and damage wires, which can easily cause short circuits and fires. The cross-connect fitting provided by the utility model has a closed cover structure, which provides better sealing, preventing small animals such as mosquitoes from entering and damaging wires, which could cause short circuits and fires.

[0071] Advantage 4: Strong structural pressure resistance: The internal structural design of the base and upper cover with guide bones and separation layer bones not only separates the cross wires in different directions inside, which is not only conducive to orderly wiring, but also enables construction workers to quickly install and connect, and can enhance the internal structural strength while reducing the risk of leakage caused by pressure or collision damage.

A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
