Description

Technical Field

[0001] This application relates to the technical field of cable fixing, and particularly to a leaky cable clamp. Background Art

[0002] A leaky coaxial cable (Leaky Coaxial Cable, abbreviated as LCR or Leaky Coax) is a specially designed coaxial cable. Its characteristic is that periodic slots or gaps are opened on the outer conductor. These slots allow the electromagnetic wave energy transmitted inside the cable to radiate outward, and at the same time, allow the external electromagnetic wave energy to be received by the cable. This two-way electromagnetic wave energy exchange ability enables the leaky coaxial cable not only to be used as a signal transmission medium but also to act as a distributed antenna. Therefore, leaky cables are commonly used in some special environments - such as providing communication coverage in places where wireless signals are difficult to reach, like in subways, railway tunnels, highway tunnels, mines, elevator shafts, and inside large buildings.

[0003] In the above special environments, the installation and fixing of leaky cables may have difficulties different from those in general environments. Taking operation as an example, different environments may lead to a reduction in the installation work efficiency. Even when installed through existing clamps - such as the Chinese patent "A Leaky Cable Clamp" with the publication number CN221201988U, the use of fixing methods such as screws will reduce the efficiency and cannot meet the fixing requirements of more points. Summary of the Utility Model

[0004] The main purpose of this application is to provide a leaky cable clamp, aiming to solve the technical problem that the installation of existing leaky cable clamps is cumbersome and leads to low efficiency.

[0005] To achieve the above object, at least one embodiment of this application proposes a leaky cable clamp, which includes: a mounting base, a sealing plate, and a clamping plate;

[0006] The mounting base is configured with an opening, including two first mounting ends located at both ends of the opening respectively. The sealing plate seals the opening and includes two second mounting ends respectively connected to the first mounting ends. The clamping plate includes two third mounting ends respectively corresponding to the positions of the second mounting ends; and,

[0007] One first mounting end of the mounting base is pin-connected to the corresponding second mounting end of the sealing plate, and the other first mounting end is connected to the other second mounting end of the sealing plate through a threaded member. One end of the threaded member is rotatably connected to one third mounting end of the clamping plate, and the end of the clamping plate far from the end connected with the threaded member is snap-connected to the corresponding second mounting end of the sealing plate.

[0008] For example, in the leaky cable clamp provided in at least one embodiment of the present application, a third mounting end of the clamping plate is pinned to one end of the threaded member, and the clamping plate rotates relative to the threaded member with the pinned position as the center of the circle, so that the other third mounting end of the clamping plate is close to or away from the corresponding second mounting end of the sealing plate.

[0009] For example, in the leaky cable clamp provided in at least one embodiment of the present application, the clamping plate is provided with a buckle at one end away from the threaded member, and the second mounting end of the sealing plate pinned to the first mounting end is provided with a slot for the buckle to be inserted into.

[0010] For example, in the leaky cable clamp provided in at least one embodiment of the present application, a pressing piece is disposed on a side of the sealing plate close to the opening.

[0011] For example, in the leaky cable clamp provided in at least one embodiment of the present application, the clamping member is configured as two separate and symmetrical fixing spring pieces.

[0012] For example, in the leaky cable clamp provided in at least one embodiment of the present application, the second mounting end of the sealing plate connected to the mounting seat via a threaded member is provided with a notch for the threaded member to pass through.

[0016] For example, in the leaky cable clamp provided in at least one embodiment of the present application, the connecting member is connected to the mounting seat by screws.

[0017] Any embodiment of the leaky cable clamp of the present application can at least achieve simple and fast installation by coordinating the structural forms of the mounting seat, the sealing plate and the clamping plate with the respective installation and connection methods, thereby improving efficiency.

[0025] The drawings in the present utility model are not strictly drawn according to the actual ratio, and the specific dimensions and quantities of each structure can be determined according to actual needs. The drawings described in the present utility model are only schematic diagrams of the structure.

[0026] As Figure 1 shown in the figure, an embodiment of the leaky cable clamp 100 provided by the present utility model is presented. In the reference direction Figure 1 shown in the figure, the leaky cable clamp 100 sequentially includes a mounting base 10, a sealing plate 20, and a clamping plate 30 from bottom to top; among them, the mounting base 10 is configured as an arc segment with an opening, including two first mounting ends 11 respectively located at the ends of the arc segment. The sealing plate 20 seals the opening of the arc segment and includes two second mounting ends 21 respectively connected to the first mounting ends 11. The clamping plate 30 includes two third mounting ends 31 respectively corresponding to the positions of the second mounting ends 21; in this embodiment, the arc segment of the mounting base 10 is not limited to Figure 1 the opening angle or length shown in the figure and can be selected according to needs. For example, a large opening with a central angle of the arc segment less than 90° may accommodate more leaky cables, while a small opening with a central angle of the arc segment greater than 180° can reduce the possibility of the leaky cable slipping out of the mounting base 10; on the other hand, the mounting base 10 is designed as an arc segment with an opening to match the cylindrical structure form of the leaky cable. This embodiment does not exclude the equivalent replacement of the mounting base 10 in this embodiment by other forms of mounting bases 10 without bringing substantial effect gains, such as a U-shaped mounting base 10. Similarly, the same applies to the sealing plate 20 and the clamping plate 30.

[0027] Specifically, one first mounting end 11 of the mounting base 10 is pin-connected to the corresponding second mounting end 21 of the sealing plate 20, and the other first mounting end 11 is connected to the other second mounting end 21 of the sealing plate 20 through a threaded member 40. One end of the threaded member 40 is rotatably connected to one third mounting end 31 of the clamping plate 30, and the end of the clamping plate 30 far from the end connected to the threaded member 40 is snap-connected to the corresponding second mounting end 21 of the sealing plate 20.

[0028] Specifically, one first mounting end 11 of the mounting base 10 is pin-connected to the corresponding second mounting end 21 of the sealing plate 20, and the other first mounting end 11 is connected to the other second mounting end 21 of the sealing plate 20 through a threaded member 40. One end of the threaded member 40 is rotatably connected to one third mounting end 31 of the clamping plate 30, and the end of the clamping plate 30 far from the end connected to the threaded member 40 is snap-connected to the corresponding second mounting end 21 of the sealing plate 20.

[0029] See Figure 1 and Figure 2Taking the illustrated direction as a reference, the first mounting end 11 on the right side of the mounting base 10 and the second mounting end 21 on the right side of the sealing plate 20 are pinned together. The sealing plate 20 can rotate relative to the mounting base 10 around the pinned joint to open the arc-shaped opening of the mounting base 10, place the leaky cable. After placement, the opening is sealed by rotating the sealing plate 20. In the sealed state, the first mounting end 11 on the left side of the mounting base 10 is aligned with the second mounting end 21 on the left side of the sealing plate 20 and fixed by a threaded member 40, such as a screw. It should be noted that using the threaded member 40 to connect and fix different components is common knowledge, and it can be understood that through holes or screw holes must exist on the corresponding components. Although this part of the feature is not explicitly pointed out in this embodiment, according to the implemented connection and fixing method and common knowledge, it should be regarded as an implicit disclosure of this part of the feature. More specifically, in this embodiment, in addition to providing through holes or screw holes for the installation of the threaded member 40, the second mounting end 21 on the left side of the sealing plate 20 can also achieve the same effect in the form of a notch 60 extending to the end edge. And this structure can avoid or reduce the difficulty of aligning the screw holes, which is more conducive to quickly installing the threaded member 40.

[0030] After the arc-shaped opening of the mounting base 10 is sealed and fixed by the sealing plate 20, in the above embodiment, the cable clamp and the installed leaky cable are further secondarily fixed by the clamping plate 30 located above the sealing plate 20. For the clamping plate 30 to effectively secondarily fix the cable clamp (and the installed leaky cable), it naturally needs to rely on the external support of the cable clamp basic system (i.e., the mounting base 10 + the sealing plate 20) - the threaded part 40. For example, both third mounting ends 31 of the clamping plate 30 are connected to the second mounting end 21 of the sealing plate 20, and it is still in internal force balance within the cable clamp basic system, so the fixing effect is actually ineffective. Specifically, the third mounting end 31 on the left side of the clamping plate 30 is rotatably connected to the top of the threaded part 40. For example, a pin hole is integrally formed or assembled at the cap end of the screw. The first mounting end 11 on the left side of the clamping plate 30 is also configured as a pin hole and is connected to the threaded part 40 through a common pin, enabling the clamping plate 30 to rotate relative to the threaded part 40 with the pin-connected position as the center of rotation, so that the other third mounting end 31 of the clamping plate 30 approaches or moves away from the corresponding second mounting end 21 of the sealing plate 20. This connection method can avoid the rotation block of the threaded part 40 caused by the clamping plate 30 during the process of sealing the mounting base 10 by the sealing plate 20, or provide a torque application point for convenient operation. In addition, the third mounting end 31 on the right side of the clamping plate 30 is connected to the second mounting end 21 on the right side of the sealing plate 20 in a snap-fit connection form. For example, the third mounting end 31 on the right side of the clamping plate 30 is configured with an inverted buckle 90, and a matching card slot is configured on the second mounting end 21 on the right side of the sealing plate 20 to achieve the snap-fit connection; of course, the snap-fit connection can also be completed in other forms. For another example, the third mounting end 31 on the right side of the clamping plate 30 is configured with an inverted buckle 90, and a redundant opening is left at the pin-connected part between the second mounting end on the right side of the sealing plate 20 and the first mounting end 11 on the right side of the mounting base 10 for the inverted buckle 90 to directly snap in.

[0031] It should be noted that in this embodiment, the clamping plate 30 is snap-fitted onto the sealing plate 20 to form a re-fixation of the overall cable clamp. It can be understood that the snap-fit fixation is a connection and fixation method achieved through micro-deformation to generate stress balance. Therefore, in the above embodiment, preferably, the material of the clamping plate 30 can be selected from aluminum alloy, stainless steel or other composite materials to ensure repeated and effective use.

[0032] When using the cable clamp of this embodiment to install and fix the leaky cable, only one threaded part 40 needs to be operated to complete the preliminary installation, and then with the help of the clamping plate 30 under external support, the basic installation system formed by the sealing plate 20 and the mounting base 10 is re-fixed in a snap-fit manner. This structural setting is simple and fast, and can effectively enhance the fixing and installation effect, improving the assembly efficiency of the cable clamp and the leaky cable.

[0033] In the leaky cable clamp 100 provided in some other embodiments of the present application, optionally based on the foregoing embodiments, a pressing member 50 is disposed on one side of the sealing plate 20 close to the arc segment. When assembling multiple bundles of leaky cables through the leaky cable clamp 100, the pressing member 50 can compact and fasten the multiple bundles of leaky cables to avoid loosening. Specifically, refer to Figure 1 or Figure 2 , the pressing member 50 is configured as two split and symmetric fixing elastic sheets in a V shape, or the pressing member 50 can also be arranged on the sealing plate 20 in a closed polygon. To achieve the pressing and fixing effect, the pressing member 50 is preferably made of an elastic material that meets certain elastic modulus requirements, and this embodiment does not limit this.

[0034] In some other embodiments of the present application, optionally based on any of the foregoing embodiments, a groove 70 or a protrusion (the protrusion is not shown) is disposed on one side of the mounting seat 10 close to the sealing plate 20. The groove 70 or the protrusion can be disposed at the bottom, side or other positions of the arc segment of the mounting seat to prevent the leaky cable from twisting, moving or even being misaligned in the clamp, and enhance the fixing performance of the clamp.

[0035] In some other embodiments of the present application, for example, optionally based on any of the foregoing embodiments, as Figure 1 or Figure 2 shown, a reinforcing member 80 is disposed on the arc segment on the side of the mounting seat 10 away from the sealing plate 20; the reinforcing member 80 arranged along the outer side of the arc segment of the mounting seat 10 is realized in the form of a reinforcing rib, forming a continuous lateral stress support, enhancing the structural strength of the arc segment, and being more durable in the scenario of installing multiple bundles of leaky cables.

[0036] For example, in the leaky cable clamp 100 provided in at least one embodiment of the present application, the leaky cable clamp 100 further includes a connecting member 200 disposed at the bottom of the mounting seat 10, and the connecting member 200 fixes the mounting seat 10 at the mounting position. Specifically, the connecting member 200 is detachably connected to the mounting seat 10 by screws.

[0037] The connecting member 200 can be used for installation and fixation in some special environments. For example, in a concrete installation environment where a hole has been drilled or a mounting position has been configured on some equipment, quick connection can be achieved through the connecting member 200. The simplest connection form of the connecting member 200 can be threaded installation.

[0038] The above are only optional embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made using the description and drawings of the present application under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
