Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and in particular to an insulated shielded cable with compression resistance and buffering. Background Technology

[0002] A cable is a type of cable used to transmit electrical signals or conduct electricity. It is usually a rope-like cable made up of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables have the characteristics of being internally energized and externally insulated, and have good transmission performance. In addition, some cables may have external structures added to improve their adaptability according to actual use needs, such as compression resistance, insulation, and shielding. However, cables do not have the function of fixing and installing during use, and they do not have good sealing function when assembled.

[0003] A search revealed a Chinese patent document (authorization announcement number CN210606744U) describing a cable with compression resistance, comprising a polyethylene filler tape. A main conductor insulation layer is fixedly installed inside the polyethylene filler tape, and a control conductor insulation layer is fixedly installed on one side of the main conductor insulation layer inside the polyethylene filler tape. This cable with compression resistance can reflect most of the sunlight when the cable is exposed to the elements, thus providing good heat insulation protection, increasing the overall service life of the cable, and enabling it to withstand some external pressure. The release of pressure is buffered by a buffer strip, resulting in good compression resistance. While the cable in the aforementioned patent has good buffering and compression resistance, it lacks fixing and installation functions during use, and also lacks good sealing functions when assembled. Utility Model Content

[0004] The purpose of this invention is to provide an insulated shielded cable with compression resistance and buffering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-crushing and buffered insulated shielded cable, comprising multiple cable bodies, a reinforcing inner core between the multiple cable bodies for increasing strength, and a protective outer layer provided on the outer periphery of the multiple cable bodies;

[0006] The outer periphery of the protective outer layer is provided with two protective half tubes for sealing and protection. Both sides of the two protective half tubes are connected to side support plates. The sides of the four side support plates are provided with multiple round holes. The round holes of two adjacent side support plates are provided with fixing bolts with nuts for fixing. The inner wall of the protective half tube is bonded with two rubber gaskets for sealing. The rubber gaskets are arc-shaped, and one end of the rubber gasket is inside the other protective half tube. The sides of the two protective half tubes are connected with multiple pull straps. The two pull straps corresponding to the positions of the two protective half tubes are connected and fixed by adjusting buckles.

[0007] As a preferred embodiment, an insulating outer layer is provided on the inner side of the protective outer layer, an insulating inner layer is sleeved on the outer periphery of the cable body, and a filler is filled between the insulating inner layer and the insulating outer layer.

[0008] As a preferred embodiment, the protective outer layer, the insulating inner layer, the insulating outer layer, and the filler are all made of rubber.

[0009] As a preferred embodiment, a flame-retardant layer is provided on the inner side of the protective outer layer, and the flame-retardant layer is located between the protective outer layer and the insulating outer layer.

[0010] As a preferred embodiment, the inner side of the protective outer layer is bonded with a fire-retardant aramid yarn braided layer, and the outer periphery of the protective outer layer is provided with anti-slip texture.

[0011] As a preferred embodiment, both the inner insulating layer and the outer insulating layer are bonded with a shielding aluminum film that has a shielding function.

[0012] As a preferred embodiment, the outer diameter of the rubber pad is smaller than the inner diameter of the protective half-tube, and the two rubber pads of the protective half-tube are staggered.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This compression-resistant and buffered insulated shielded cable, when in use, uses two protective half-tubes with rubber pads to fix the outer protective layer around the cable body. After adjusting the pull strap, the pull strap can be hung or tied to a designated position to satisfy the fixing and installation functions. When it is necessary to assemble the cable, the two ends are processed and then connected. At this time, the protective half-tubes are used to fix it, and the rubber pads can achieve a seal. The two rubber pads are staggered to ensure the sealing performance.

[0015] In actual use, the protective outer layer, the inner insulation layer, the outer insulation layer and the filler are all made of rubber, which can play a multiple insulation role. The aramid fiber braided layer and the flame retardant layer can provide fire protection. The outer periphery of the inner insulation layer and the outer insulation layer are bonded with shielding aluminum film with shielding function to achieve double shielding protection.

[0016] This compression-resistant, buffered, insulated shielded cable can not only be fixed and installed, but also sealed in combination. Attached Figure Description

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] Please see Figures 1 to 3As shown, an anti-crushing buffer insulated shielded cable is provided in this embodiment, which includes multiple cable bodies 1, a reinforcing inner core 2 between the multiple cable bodies 1 for increasing strength, and a protective outer layer 3 provided on the outer periphery of the multiple cable bodies 1.

[0028] Two protective half-tubes 4 for sealing are provided on the outer periphery of the outer protective layer 3. Side support plates 5 are connected to both sides of each of the two protective half-tubes 4. Multiple round holes are opened on the sides of each of the four side support plates 5. Fixing bolts 6 with nuts are installed in the round holes of adjacent side support plates 5 for fixing. Two rubber gaskets 14 for sealing are adhered to the inner wall of the protective half-tube 4. The rubber gaskets 14 are arc-shaped, with their outer diameter shorter than the inner diameter of the protective half-tube 4. The two rubber gaskets 14 are staggered, with one end of each rubber gasket 14 located inside the other protective half-tube 4. Multiple pull straps 7 are connected to the sides of the two protective half-tubes 4. The two pull straps 7 corresponding to the positions of the two protective half-tubes 4 are connected and fixed by adjusting buckles. When it is necessary to assemble them, the two ends are processed and connected, and the protective half-tubes 4 are used to fix them. For positions that are not assembled, the two protective half-tubes 4, together with the rubber pads 14, can fix the outer protective layer 3 of the cable body 1. Rotate the fixing bolts 6 to fix the two side support plates 5, so that the protective half-tubes 4 are fixed and tightened. After adjusting the pull straps 7, the pull straps 7 are hung or tied to the designated position.

[0029] To meet practical needs, an insulating outer layer 8 is provided on the inner side of the protective outer layer 3, and an insulating inner layer 9 is sleeved on the outer periphery of the cable body 1. A filler 10 is filled between the insulating inner layer 9 and the insulating outer layer 8. The materials of the protective outer layer 3, the insulating inner layer 9, the insulating outer layer 8 and the filler 10 are all rubber, which can play a multiple insulation role.

[0030] A flame-retardant layer 11 is provided on the inner side of the protective outer layer 3. The flame-retardant layer 11 is located between the protective outer layer 3 and the insulating outer layer 8. An aramid fiber braided layer 12 with fire-retardant function is bonded to the inner side of the protective outer layer 3. Anti-slip texture is provided on the outer periphery of the protective outer layer 3. The aramid fiber braided layer 12 and the flame-retardant layer 11 can provide fire protection.

[0031] To provide shielding protection, shielding aluminum film 13 with shielding function is adhered to the outer periphery of both the inner insulating layer 9 and the outer insulating layer 8, thus achieving double shielding protection.

[0032] Working principle

[0033] When this anti-extrusion buffer insulated shielded cable needs to be assembled, the two ends are treated and then connected. The protective half tube 4 is used to fix it. For positions that are not assembled, the two protective half tubes 4, together with the rubber pads 14, can fix the outer protective layer 3 around the cable body 1. The two side support plates 5 are fixed by rotating the fixing bolts 6, so that the protective half tube 4 is fixed and tightened. Then, after adjusting the pull strap 7, the pull strap 7 is hung in the designated position or tied in the designated position.

[0034] In actual use, the protective outer layer 3, the insulating inner layer 9, the insulating outer layer 8 and the filler 10 are all made of rubber, which can play a multiple insulation role. The aramid fiber braided layer 12 and the flame retardant layer 11 can provide fire protection. The outer periphery of the insulating inner layer 9 and the insulating outer layer 8 are both bonded with a shielding aluminum film 13 with shielding function to achieve double shielding protection.
