Description

Technical Field

[0001] This application relates to the field of electrical installation components, and more particularly to a cable fixing device. Background Technology

[0002] During cable laying, if the distance between cables is insufficient, magnetic field coupling may exacerbate the imbalance of three-phase current, increase line loss and voltage fluctuation, and may also cause partial discharge due to insulation aging. Long-term accumulation may break down the insulation and reduce heat dissipation efficiency.

[0003] For buried cables, the lack of cable fixation during burial causes the distance between cables to change due to the compression of the filling material, making the cable spacing uncontrollable. Utility Model Content

[0032] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0034] like Figures 1 to 4 As shown in the figure, this application embodiment provides a cable fixing device, which includes a fastening structure 1 and a connecting structure 2. The fastening structure 1 has at least two components, each including an upper fastener 11 and a lower fastener 12, which are connected to form a cable clamping cavity for securing the cable 10. The connecting structure 2 has at least one component, and its length is adjustable. The connecting structure 2 connects between two fastening structures 1, and the fastening structure 1 can connect to at least one connecting structure 2.

[0035] Understandably, this cable fixing device, by setting at least two fastening structures and at least one connecting structure, can fix the cable through the fastening structures, and can adjust the spacing between the two cables through the connecting structure between the two fastening structures, thereby flexibly adjusting the cable spacing and making the cable spacing controllable during laying.

[0036] When the aforementioned fastening structure 1 can connect to a single connecting structure 2, two cables 10 can be fixed using two fastening structures 1 and one connecting structure 2. If the fastening structure 1 can connect to two or more connecting structures 2, multiple cables 10 can be fixed using fastening structures 1 and connecting structures 2. For example, for three cables 10, three fastening structures 1 and two connecting structures 2 are provided, with the middle fastening structure 1 connecting two connecting structures 2.

[0037] Both the upper fastener 11 and the lower fastener 12 have locking grooves. After the upper fastener 11 and the lower fastener 12 are connected, the two locking grooves form the cable locking cavity. The locking grooves are matched with the shape of the cable 10. For example, if the cable 10 is a round cable, then the locking groove is a semi-circular groove.

[0038] In some embodiments, the upper fastener 11 and the lower fastener 12 are detachably connected.

[0039] Understandably, by making the upper fastener 11 and the lower fastener 12 detachable, it is convenient to remove the upper fastener 11 and the lower fastener 12 when the cable 10 is subsequently inspected, thereby releasing the fastening structure 1 from fixing the cable 10.

[0040] Specifically, one of the upper fastener 11 and the lower fastener 12 is provided with a pin 3, and the other is provided with a locking hole 42 for the pin 3 to be inserted or removed.

[0041] The aforementioned pin 3 includes a pin body 31 and an arc-shaped protrusion 32. One end of the pin body 31 is connected to the upper fastener 11 or the lower fastener 12 along its length, and the other end is provided with the arc-shaped protrusion 32. The insertion hole 4 includes a communicating insertion hole 41 and a locking hole 42 perpendicular to the insertion hole 41 and used to engage the arc-shaped protrusion 32.

[0042] When the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is pressed, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 is engaged in the socket 42 and protrudes from the socket 42.

[0043] Understandably, when the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is restricted by the insertion hole 41, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 and the locking hole 42 are aligned. At this time, the arc-shaped protrusion 32, which is released from restriction, extends into the locking hole 42 under the elastic force of the pin body 31 returning to its original shape, thus realizing the locking of the pin 3 and the socket 4. Moreover, since the arc-shaped protrusion 32 is exposed from the locking hole 42 when it is locked in, during disassembly, the arc-shaped protrusion 32 is pressed through the locking hole 42 to make the arc-shaped protrusion 32 exit the locking hole 42, thereby realizing the disassembly of the upper fastener 11 and the lower fastener 12.

[0044] It should be noted that when the aforementioned arc-shaped protrusion 32 is inserted into the card hole 42, part of the arc-shaped protrusion 32 may protrude from the card hole, or the entire arc-shaped protrusion 32 may be located inside the card hole 42, that is, the arc-shaped protrusion 32 does not protrude from the card hole 42.

[0045] Furthermore, multiple pins 3 and sockets 4 are provided, and each corresponds to the other. By providing multiple pins 3 and multiple sockets 4, the connection stability between the upper fastener 11 and the lower fastener 12 is improved.

[0046] Furthermore, one of the upper fastener 11 and the lower fastener 12 is provided with a positioning post 111, and the other is provided with a positioning hole 121 for the positioning post 111 to be inserted. Thus, the positioning of the upper fastener 11 and the lower fastener 12 can be achieved through the cooperation of the positioning post 111 and the positioning hole 121.

[0047] For example, refer to Figure 2 and Figure 3 The upper fastener 11 is provided with a pin 3, and the lower fastener 12 is provided with a socket 4. Alternatively, the upper fastener can be provided with a socket, and the lower fastener can be provided with a pin. The pin 3 can be integrally formed with the upper fastener 11 or the lower fastener 12.

[0048] Reference Figures 1 to 3 The aforementioned upper fastener 11 and / or lower fastener 12 are detachably connected to the connecting structure 2.

[0049] Understandably, by configuring the upper fastener 11 and / or the lower fastener 12 to be detachably connected to the connection structure 2, it is convenient to disassemble the fastening structure 1 and the connection structure during subsequent maintenance of the cable 10.

[0050] Specifically, the upper fastener 11 and / or the lower fastener 12 are provided with pins 3, and the connecting structure 2 is provided with sockets 4 for the pins 3 to be inserted or removed.

[0051] The aforementioned pin 3 includes a pin body 31 and an arc-shaped protrusion 32. One end of the pin body 31 is connected to the upper fastener 11 or the lower fastener 12 along its length, and the other end is provided with the arc-shaped protrusion 32. The insertion hole 4 includes a communicating insertion hole 41 and a locking hole 42 perpendicular to the insertion hole 41 and used to engage the arc-shaped protrusion 32.

[0052] When the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is pressed, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 is engaged in the socket 42 and protrudes from the socket 42.

[0053] Understandably, when the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is restricted by the insertion hole 41, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 and the locking hole 42 are aligned. At this time, the arc-shaped protrusion 32, which is released from restriction, extends into the locking hole 42 under the elastic force of the pin body 31 returning to its original shape, thus realizing the locking of the pin 3 and the socket 4. Moreover, since the arc-shaped protrusion 32 is exposed from the locking hole 42 when it is locked in, during disassembly, the arc-shaped protrusion 32 is pressed through the locking hole 42 to make the arc-shaped protrusion 32 exit the locking hole 42, thereby realizing the disassembly of the upper fastener 11 or the lower fastener 12 from the connecting structure 2.

[0054] It should be noted that when the aforementioned arc-shaped protrusion 32 is inserted into the card hole 42, part of the arc-shaped protrusion 32 may protrude from the card hole 42, or the entire arc-shaped protrusion 32 may be located inside the card hole 42, that is, the arc-shaped protrusion 32 does not protrude from the card hole 42.

[0055] Furthermore, the upper fastener 11 and / or the lower fastener 12 may each be provided with a pin 3 on opposite sides, so that the fastening structure 1 can connect two connecting structures 2, thereby enabling the fixing of more than three cables 10.

[0056] For example, refer to Figure 1 Both the upper fastener 11 and the lower fastener 12 are provided with pins 3, and the connecting structure 2 is provided with holes 4. In this way, both the upper fastener 11 and the lower fastener 12 are connected to the connecting structure 2, which can improve the connection stability between the fastening structure 1 and the connecting structure 2.

[0057] In some embodiments, refer to Figure 4 The aforementioned connection structure 2 includes a first connecting portion 21, a second connecting portion 22, and a fixing component 23. The first connecting portion 21 has an insertion rod 211, the second connecting portion 22 has a receiving hole 221 for the insertion rod 211 to extend into, and the fixing component 23 can fasten or loosen the insertion rod 211 relative to the second connecting portion 22. Both the first connecting portion 21 and the second connecting portion 22 are provided with the aforementioned insertion hole 4.

[0058] Understandably, the length of the insertion rod 211 extending into the receiving hole 221 can be adjusted by fixing component 23, thereby adjusting the overall length of the connecting structure 2. In this way, the distance between the two fastening structures 1, that is, the spacing between the two cables 10, can be adjusted according to actual needs.

[0059] Furthermore, the second connecting portion 22 is provided with a strip-shaped hole 222 that communicates with the receiving hole 221 and extends along the depth direction of the receiving hole 221, and two strip-shaped holes 222 are provided opposite to each other.

[0060] The fixing component 23 includes a connecting rod 231 and limiting members 232 disposed at both ends of the connecting rod 231 and threadedly connected to the connecting rod 231.

[0061] The connecting rod 231 passes through the inserting rod 211, and two strip holes 222 extend from both ends of the connecting rod 231. The limiting member 232 can rotate relative to the connecting rod 231 to tighten or loosen the second connecting part 22.

[0062] Understandably, the limiting member 232 and the connecting rod 231 are designed so that when the overall length of the connecting structure 2 needs to be adjusted, turning the limiting member 232 loosens the second connecting part 22, allowing the connecting rod 231 and the extension rod 211 to move, thereby adjusting the length of the extension rod 211 extending into the receiving hole 221. After adjustment, turning the limiting member 232 makes both limiting members 232 press against the second connecting part 22, thus fixing the extension rod 211 and the second connecting part 22 relatively. At this time, the extension rod 211 cannot move, ensuring the stability of the length of the connecting structure 2.

[0063] Furthermore, the aforementioned extension rod 211 is provided with scale lines. This allows the user to easily determine the adjustment length of the connecting structure 2 by observing the scale lines. For example, when there are multiple connecting structures 2, the scale lines can ensure that the lengths of multiple connecting structures 2 are adjusted to be the same.

[0064] For example, refer to Figures 1 to 4 The cable fixing device includes a fastening structure 1 and a connecting structure 2. The fastening structure 1 has at least two components, each including an upper fastener 11 and a lower fastener 12, which connect to form a cable clamping cavity for securing the cable 10. The connecting structure 2 has at least one component, and its length is adjustable. The connecting structure 2 connects between two fastening structures 1, and each fastening structure 1 can connect to at least one connecting structure 2.

[0065] There are two fastening structures 1. One fastening structure 1 can connect to one connecting structure 2, and the other fastening structure 1 can connect to two connecting structures 2.

[0066] The upper fastener 11 and the lower fastener 12 are detachably connected. The upper fastener 11 is provided with a pin 3, and the lower fastener 12 is provided with a socket 4 for the pin 3 to be inserted or removed.

[0067] The aforementioned pin 3 includes a pin body 31 and an arc-shaped protrusion 32. One end of the pin body 31 is connected to the upper fastener 11 along its length, and the other end is provided with the arc-shaped protrusion 32. The insertion hole 4 includes a communicating insertion hole 41 and a locking hole 42 perpendicular to the insertion hole 41 and used to engage the arc-shaped protrusion 32.

[0068] When the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is pressed, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 is engaged in the socket 42 and protrudes from the socket 42.

[0069] Multiple pins 3 and multiple sockets 4 are provided, and they correspond one-to-one. By providing multiple pins 3 and multiple sockets 4, the connection stability between the upper fastener 11 and the lower fastener 12 is improved.

[0070] The upper fastener 11 and the lower fastener 12 are both detachably connected to the connecting structure 2.

[0071] Specifically, both the upper fastener 11 and the lower fastener 12 are provided with pins 3, and the connecting structure 2 is provided with a socket 4 for the pins 3 to be inserted or removed.

[0072] The aforementioned pin 3 includes a pin body 31 and an arc-shaped protrusion 32. One end of the pin body 31 in the length direction is connected to the upper fastener 11 or the lower fastener 12, and the other end is provided with the arc-shaped protrusion 32. The insertion hole 4 includes a communicating insertion hole 41 and a locking hole 42 perpendicular to the insertion hole 41 and used to engage the arc-shaped protrusion 32.

[0073] When the pin 3 is inserted into the socket 4, the arc-shaped protrusion 32 is pressed, causing the pin body 31 to undergo elastic deformation. When the pin 3 is inserted to the preset position, the arc-shaped protrusion 32 is engaged in the socket 42 and protrudes from the socket 42.

[0074] Multiple pins 3 and multiple holes 4 are provided, and each one corresponds to the other. By providing multiple pins 3 and multiple holes 4, the connection stability between the fastening structure 1 and the connecting structure 2 is improved.

[0075] The aforementioned connecting structure 2 includes a first connecting portion 21, a second connecting portion 22, and a fixing component 23. The first connecting portion 21 has an insertion rod 211, the second connecting portion 22 has a receiving hole 221 for the insertion rod 211 to extend into, and the fixing component 23 can fasten or loosen the insertion rod 211 relative to the second connecting portion 22. Both the first connecting portion 21 and the second connecting portion 22 are provided with the aforementioned insertion hole 4.

[0076] The second connecting part 22 is provided with a strip hole 222 that communicates with the receiving hole 221 and extends along the depth direction of the receiving hole 221. There are two strip holes 222 arranged opposite to each other.

[0077] The fixing component 23 includes a connecting rod 231 and limiting members 232 disposed at both ends of the connecting rod 231 and threadedly connected to the connecting rod 231.

[0078] The connecting rod 231 passes through the inserting rod 211, and two strip holes 222 extend from both ends of the connecting rod 231. The limiting member 232 can rotate relative to the connecting rod 231 to tighten or loosen the second connecting part 22.

[0079] The aforementioned extension rod 211 is provided with scale lines.

[0080] Thus, during cable 10 laying, the cable fixing device can be placed horizontally, the cable 10 is secured by the fastening structure 1, and the spacing between the two cables 10 is adjusted by the connecting structure 2. When there are two cables 10, two fastening structures 1 are selected, and one connecting structure 2 is selected. In this case, the fastening structure 1 can be set to connect only one connecting structure 2. When the number of cables 10 exceeds two, the number of fastening structures 1 is the same as the number of cables 10, and the number of connecting structures 2 is one less than the number of cables 10. In this case, the fastening structure 1 can be set to connect two connecting structures 2.
